STFC opens the market

On November 17, 2005, then Chairman and CEO Bob
Moone rang the ceremonial bell that opened the NASDAQ
stock market. More than fourteen years earlier, the fledgling
downstream holding company of the State Auto group had
been offered to the public at $13.50 per share (or $2.25,
adjusted for splits). As Jeff Singer, NASDAQ’s regional vice
president, stepped to the microphone to introduce Moone, a
blue screen high above the podium showed STFC's closing
price from the day before, $33.22, a nearly 1400% increase
over the IPO price.

The ceremony, for those who have never witnessed the event,
is carefully choreographed, tightly scheduled and full of energy.
Moone, who was joined at the podium by members of the
STFC management team, was given 150 seconds to tell the
STFC story. Speaking into the studio lights, his image project-
ed on the facade of NASDAQ’s seven story headquarters on
Times Square, Moone let the investment world in on the com-
pany’s “secret.”

“Our strategy for success is fairly straightforward. That is, we
intend to earn an underwriting profit in every line, every state,
every year. Needless to say, particularly in years with major
storm activity, that goal is not always met. But, this objective
has kept our people well enough focused on profit to have reg-
ularly outpaced both the industry as a whole and our peer
group over 14-plus years.

“As I’ve told our people countless times, only those insurance
companies that can deliver their products efficiently deserve to
stay in business. Thus, we look to become ever more efficient
through the use of technology and emphasis on controlling
costs. All in all, we are very proud of the company’s record of
success and the employees and independent agents who
made it happen.”

Someone noted that only a former underwriter could have
packed so many facts into a two and one-half minute speech.
As the small studio crowd cheered and the CNBC audience
watched at home, Moone autographed a glass screen and his
signature was then projected on NASDAQ’s facade. The mar-
ket was officially open. You know what they say about New
York…if you can make it there…

The STFC team that represented the company at the
NASDAQ market opening included Craig Segbers, 
senior IT architect; Win Logan, ASec communications 
officer; John Lowther, Sr VP and general counsel, 
Terrence Bowshier, VP investor relations; Mark Blackburn, 
Sr VP insurance operations; Steve English, AVP financial 
planning; Bob Moone; Cindy Powell, VP comptroller; and
Steve Johnston, Sr VP and CFO.  Behind them is
NASDAQ headquarters and the video screen that
welcomed STFC throughout the morning and broadcast
live the opening ceremony.

Letter to our shareholders

excellent 90.1%. We achieved this despite major cata-
strophe losses that plagued the country and our industry.
2005 will long be remembered as a year that set meteoro-
logical records in terms of hurricanes, the length of the
tropical storm season and the tragic severity of Hurricane
Katrina. Even though our company is not licensed to do
business in Louisiana, we do have clients in Mississippi
and Alabama who suffered from the ravages of Katrina.
While the damage in these states was horrific, I am

pleased to report that our claims staff responded quickly,
compassionately and effectively to the needs of our poli-
cyholders and agency partners. The fact that we
emerged with a strong underwriting profit despite the
unprecedented impact of Katrina and other wind and hail
events is strong testimony to the health of our core busi-
ness. Disciplined underwriting and responsive claim
capability remain hallmarks of State Auto’s past and
future.

Customer Focus

State Auto's most important partner remains the inde-
pendent agent. The independent agents who represent
us make virtually all purchasing decisions on behalf of our
policyholders – both current and prospective. Our job is
to provide them the products, systems and services that
will enable them to produce more profitable business for
us and satisfy the needs of their clientele.

We made good progress in 2005 in enhancing our cus-

tomer focus. Let me give you a couple of examples.

(cid:2) Last year we began the roll out of our internet-based
system, netXpress, which enables the submission of
personal lines new business and policy changes quickly
and electronically from our agency partners. By the
end of the year, 90% of these transactions were directly
communicated to our systems from the agents’ desktop.
This saves everyone time and money and allows us the
opportunity to increase our share of new business
activity. We have now begun the development of a 
similar capability for commercial lines.

(cid:2) We also began the roll out of a new private passenger 
automobile program – CustomFitSM. This new product 
allows us to use a wide variety of risk attributes to  
better predict losses, increase the number of price 
points and ensure better risk/rate balance. CustomFit 
allows us to not only be more competitive for a wider  
array of accounts, but also should enable us to both 
grow and maintain our legacy of consistent underwriting 
profitability.

Robert P. Restrepo Jr., chairman of the board, 
president and CEO

2005 was another outstanding year for State Auto

Financial Corporation. Once again we demonstrated our
ability to sustain strong underwriting performance and
build shareholder value, despite an increasingly competi-
tive market and unprecedented catastrophes.

The year represented both continuity in our excellent
results and an orderly transition in leadership. As you
know, Bob Moone announced his intention to retire during
last year’s Annual Meeting. The succession process
ended with my appointment in February 2006. I want to
thank the Board for its confidence in the company and my
ability to lead it.

I also want to acknowledge the significant contributions
Bob Moone has made to the company and its sharehold-
ers. During his 36-year career at State Auto, Bob has
either led or touched virtually every person and every
facet of the company’s operations. Our success has been
unusually influenced by Bob’s personality and leadership.
He has been a role model for all of us. His integrity, disci-
pline and caring nature has left a lasting imprint on the
company – both its character and its culture. Bob has
truly left State Auto a much better company than when he
joined us. We are in his debt and we wish him and his
wife, Anna, the very best in the future.

Over the past several months, I have had the opportuni-

ty to meet and discuss the company with many of our
employees, agents, regulators and investors. In addition,
I have reviewed our past accomplishments and plans to
sustain our track record of success in the future. Let me
share some of my observations with you.

Combined Ratio

Combined ratio and underwriting profit continue to be
our corporate credo. Our combined ratio for 2005 was an

4

(cid:2) Our claim organization continues to make rapid strides 
in improving our responsiveness. We have in place a 
goal of two-hour contact with claimants. Our goal is 
critical because speed ensures high quality service, fair  
claim settlements and reduced friction and cost – all of  
which are critical to customer focus and underwriting 
profitability. We expect even more success in the future 
as we redesign our claims business processes and   
introduce new technology.

Capital Management

Our corporate structure as a mutual insurance company
with a downstream publicly-held stock company remains a
distinctive competitive advantage. It gives us both the flex-
ibility and the time necessary to take a longer term view
of the business, manage our capital more effectively and
achieve better spread of risk. That we produced the kind
of underwriting profit we did, despite the unprecedented
catastrophe losses experienced by the industry in 2005,
showcases our ability to manage risk, allocate capital and
build equity. These attributes also provided us the oppor-
tunity to double the dividend last year and they will remain
a keystone to our strategies for the future.

Culture

Culture is a community of shared values, beliefs, behav-

In our business anyone can

iors and communications.
copy products, systems and services. It is virtually impos-
sible to copy culture. At State Auto we have a tradition of
dignity, respect and caring for one another and our
agency partners. This distinguishes us as an employer,
agency partner and insurance product provider, and rep-
resents a real, distinct competitive advantage. I am com-
mitted to preserving and building our strong culture, which
is our most important legacy.

In addition to achieving record-breaking financial results,
we also received a record number of awards and recogni-

tion as a leader in our industry. The most noteworthy of
which are:

(cid:2) Forbes names State Auto Financial Corporation the

Best Managed Insurance Company in America for 2006;

(cid:2) State Auto Mutual is one of only fourteen insurance
companies to be rated A+ by A.M. Best since 1954;

(cid:2) Recipient (for the third time) of the Mergent Award 

for ten or more years of dividend increases. Only 3% of 
public companies are so recognized;

(cid:2) Forbes Platinum 400 company;

(cid:2) State Auto was the only featured insurance company in 
the book Blueprint to a Billion by David G. Thomson;

(cid:2) Chosen to open the session on the NASDAQ 

Exchange; and

(cid:2) Strategic Insurance Software (an STFC affiliate) named 
Upload Vendor of the Year by the ACORD Organization.

2005 was truly a remarkable year for State Auto. While
my time with the company has been brief, I have already
seen that our people are smart, experienced, energetic
and totally committed to achieve success. I am thrilled to
have the opportunity to join this terrific organization and
help lead the company into what I know will be a distinc-
tive and distinguished future.

Sincerely,

Robert P. Restrepo, Jr.
Chairman of the Board
President and Chief Executive Officer

2005

The following commentaries on your company’s 2005 performance are provided by STFC’s Financial,
Underwriting, Sales, Claims, IT and Governance staffs.  Financial details are provided in the Form 10-K section 
that follows the summaries.

Financial

State Auto Financial Corporation (STFC) posted record
earnings in 2005 for the third consecutive year. The strong
performance was widely recognized as outstanding.
Probably most important to you as a shareholder was the
recognition by the stock market. STFC’s stock price rose
by 41% which far exceeded the return of the S&P 500
index.

The strong performance also positioned us to double the

quarterly dividend from $0.045 to $0.090 during 2005.
STFC has paid a dividend every quarter since the initial
public offering on June 28, 1991 and increased the divi-
dend every single year. This dividend performance was
recognized by Mergent, as it named us a “Dividend
Achiever” for the third straight year.

STFC has garnered several other prestigious awards in
2005. While relative prestige is in the eye of the beholder,
being named a “2005 Premium Player” by Sandler O’Neill
& Partners, L.P. best recognizes the consistency of a
company’s performance.

Sandler O’Neill, a well-respected Wall Street investment
firm, incorporates both recent and long term performance
into its ranking system. Specifically, the firm looks at:

1) One year earnings per share growth, 

2) Five year earnings per share growth, 

3) One year return on equity, 

4) Five year average return on equity and 

5) Five year average book value growth. 

As tough as it is to perform at a high level for even a
short time period, it is exponentially more difficult to sus-
tain consistently high performance for multiple years. As
the nearby charts describe in more detail, STFC has per-
formed strongly over virtually every time period since the
IPO in 1991. The highlights include:

Our challenge, of course, is to continue the record of per-
formance noted above. We recognize that we are operat-
ing in an increasingly competitive market place driven by
companies that have different underwriting performance
expectations from ours. Pressures and changes that we
believe we can foresee in the marketplace will require
sound business decisions, thoughtful judgments and a will-
ingness to stay focused on the fundamentals that got us to
this lofty perch. There’s nothing fancy about that strategy; it
simply requires discipline. We have plenty of that.

Underwriting

When we are asked what sets us apart as a company, we
generally begin with the comment, “We’re good underwrit-
ers.” How’s that for an exciting revelation?  But it’s amaz-
ing how many insurance companies have that further
down their list of “keys to success.”

We often say that good underwriting generates long-
term sales. It is an approach that focuses on both sides
of the insurance premium dollar – loss cost containment
and premium income.

The concept is simple. When we underwrite well, we
contain loss costs. When we contain loss costs, we con-
trol our base rate needs. When we limit base rates, we
position ourselves for long-term sales viability. A commit-

6

ment to strong underwriting requires discipline, which is
different from rigidity. Discipline means being committed
to – and empowered by – underwriting basics:

(cid:2) Fact finding. The more information we know about a 
risk, the better we can evaluate it for acceptability and 
pricing. The advancements of the information age  
leave our underwriters well-equipped for their next 
underwriting step.

(cid:2) Loss potential evaluation. Underwriters work hard at 

drawing accurate risk implications from the risk-related 
information we receive both from our application and 
third parties. And we work steadily in training our 
underwriters how to better evaluate accounts.

(cid:2) Risk treatment options. Knowing and evaluating risk 
information empowers underwriters with the flexibility 
needed to determine how best to handle an account.
Coverage conditions, loss control measures and pricing 
are among the tools an underwriter has to make an 
account acceptable to State Auto and, again, our under- 
writers work constantly in developing their risk treat- 
ment expertise.

The pricing side of underwriting goes far beyond the
notion of premiums exceeding costs. While rate adequa-
cy is certainly the top priority, winning in today’s insurance
environment requires more sophisticated rate modeling –
a greater ability to differentiate one account from another,
by pricing at a more granular level. Developed and imple-
mented well, finely tuned rate structures strengthen our
ability to recognize and compete for better accounts on
one hand, and also to generate a more appropriate rate
for higher-hazard risks.

In the past year, we implemented enhanced pricing

models, and we will continue our efforts to develop them
further. Pricing technology is a key component of our
ongoing underwriting success.

Sales

STFC’s sales numbers compare favorably to the indus-
try’s for 2005. This is not the same as suggesting that the
industry growth was “favorable.” Our commitment to prof-
itability has always come before our commitment to out-
grow the industry, something we have done anyway
thanks to acquisitions and the service and consistency
that agents have come to appreciate and reward.

When analysts and shareholders ask what we’re doing

to grow “organic sales,” we immediately point to our inter-
nal and external sales training and development pro-
grams. We enjoy the benefit of “owning” the premiere
agency training program in the country, called PaceSetter.
Coming up on its 10th anniversary in 2006, PaceSetter
features an in-depth, two-week classroom training session
– provided in the Home Office – over-viewing State Auto’s
underwriting philosophy and sales “best practices.” It
ends with the PaceSetter graduate being assigned a
PaceSetter coach for one year after the Home Office
training ends. The 2005 PaceSetter graduates wrote more
than $7.4 million in new premium for the State Auto com-
panies – an all-time high.

Internally, the Sales staff has an aggressive training

schedule for our underwriters that takes us to each
branch at least twice during the year. We have also
emphasized the use of the Principles of Ethical Influence,
developed by Dr. Robert Cialdini, in order to provide a
solid basis for positive interaction with our agency part-
ners and insureds. Almost one-third of all State Auto
associates have been involved in this training. In this
company we are fond of reminding each other that
Everybody Sells State Auto. We have found some
poignant, clever, serious and – yes – corny ways to bring
that home, but the fact is anyone who hangs around our
company for a period of time comes away impressed with
how friendly, dedicated, committed and informed we are.

Here are the other sales programs that will help lead to
our sales success:

(cid:2) Paying attention to retention. All companies lose busi- 

ness at the same time they find it (if you find more than 
you lose, sales increase). We decided to study why  
insureds would leave an agency and, when appropri- 
ate, what we could do to keep them. In 2005, over 50 
personal lines underwriters actively worked with over 
140 key agency partners to study the loss of desirable 
business, and already this effort is paying dividends.

(cid:2) Bucking the trend. Over the last decade or so, most of 
the companies STFC competes with have consolidated 
their operations and brought their field reps back 
inside. We feel this is exactly the opposite of what 
needs to be done. We know this is still a relationship  
business, and we realize our field presence gives us a 
leg up on developing – and maintaining – strong rela-
tionships with our agents.

(cid:2) Drafting blue-chippers. We have a disciplined, 

thorough due-diligence process we put all agency 
prospects through. Only the “best” survive. In 2005, 
our goal was to appoint 56 high quality agencies that  
would meet our demanding standards. We ended up 
appointing 58. These agencies should help your  
company grow in written premium and profits in the 
years ahead.

Claims

It may surprise some readers to learn that major cata-
strophes – as sad and terrifying and costly as they can be
– are not the litmus test of a company’s claims skills.
While we take great pride in our CAT team’s quick, com-
passionate and thorough handling of disaster-related
claims, insurance companies reflexively deploy inordinate
resources and expend amazing energy – as they should –
on concentrated losses. It is understood that every year
and every month and every day, our company and our
industry will have opportunities – some dramatic, most not
so dramatic – to demonstrate why this business was cre-
ated, why it buttresses and safeguards our economy and
why, until a loss occurs, an insurance policy is simply a
promise. How a company delivers on its promise deter-
mines in large measure how we are judged by con-
sumers, agents and shareholders.

There is no magic to our approach. Here is the claims

division’s commitment:

To pay what we owe, no more and no less, and to do so

with fair, fast and friendly service.

We want our people to be fair. They need to recognize

the coverages that are involved and make proper deci-
sions about what is to be paid and what does not get
paid.

We want our claims service to be fast. When insureds

suffer losses, they are, at the least, inconvenienced,
sometimes devastated. But whether the claim is large or
small, each claim is to be handled as quickly as fairness
allows.

We also want the service to be friendly. Policyholders
(and claimants) who require our help may be hurt, con-
fused or uncertain about what happens next. Our cus-
tomers should expect to work with confident, reassuring
and capable claims associates who treat each claim as if
it is the only one assigned to them.

We accomplish all of this by hiring intelligent and com-
passionate individuals and then training them thoroughly
in the fundamentals. And we keep training them through-
out their careers. We also are constantly reviewing the
tools we give them: everything from a safer step ladder to
smarter estimating software to advanced communication
systems.

In 2005, the Claims Division's Special Investigations Unit

(SIU) saved the companies $4 for each $1 in expense
incurred. The SIU is a resource to help insure the legiti-
macy of an insurance loss and to verify the dollar amount
claimed.

Information 
Technology

The lifeblood of State Auto is the strength of the relation-

ship with our independent agents, and information tech-
nology (IT) is the transport mechanism that nourishes
these relationships every day. State Auto has a track
record of creating and sustaining long-lasting, satisfying
customer experiences with our information technology.
The success of the company’s growing emphasis on

“ease of doing business” is measured largely by our
advancements in technology and how they are perceived
and utilized by agents and consumers. In 2005, IT can
point to the following accomplishments as a measure of
our performance:

(cid:2) AgentSite Dashboard, a new feature on the company’s 
state-of-the-art on-line business processing and data 
management system, allowed us to eliminate paper for 
the majority of our personal lines business transactions 
with agents.

(cid:2) State Auto averages 25,000 hits per month to AgentSite 
that are initiated directly from various agency manage- 
ment systems via Internet connections.

(cid:2) Apollo, our underwriting decision system, reviewed 
171,000 automobile and homeowners transactions.
Fifty-two percent (52%) of the new business transac- 
tions reviewed by Apollo were accepted and did not 
require underwriter review. Eighty-two percent (82%) 
of endorsement transactions were accepted and did 
not require underwriter review.

(cid:2) Agents uploaded 432,000 personal lines endorsements 
and 86,000 personal lines new business transactions.
Through netXpress, almost 87% of our personal lines 
new business was submitted electronically. (The goal 
was 80%.)

(cid:2) State Auto received the 2005 ACORD Certification 

Award for P&C Surety XML.

(cid:2) We now house over 500 million document images that 
are accessible for agents and company associates to 
view on demand. This earned State Auto the Best  
Application – Improving Customer Service award at the 
Mobius national user group meeting.

The common thread among all stakeholders is that they
expect State Auto information technology to be fast, reli-
able, and effective. Orchestrating these expectations is
something we work very hard at delivering.

Governance

Until a few years ago, one rarely heard the word gover-

nance in the context of business. Today, governance
includes within its scope issues like compliance, ethics,
“tone at the top” and the Sarbanes-Oxley Act of 2002
(SOX).

Our key accomplishments in the area of governance (in

addition to the absence of negative events) include:

(cid:2) The completion of SOX 404 compliance, which relates 
to the documentation of internal controls over financial 
reporting with no material weaknesses or significant 
deficiencies.

(cid:2) The establishment over two years ago of an 800 num-
ber “hotline” for any employee or other person to use
to confidentially report alleged or perceived wrongdoing
by any employee. Our Ethics line has received fewer
than 10 calls in the two plus years it has been in place
and none has involved financial matters.

(cid:2) The establishment of a Compliance Officer position, 

which oversees the creation and administration of an 
annual company-wide compliance questionnaire  
process in which every employee and director is 
required to complete and sign a form that solicits  
disclosure of violations of the Code of Business  
Conduct.

(cid:2) Ethics training for all employees, which we began to  
roll out in 2005 in the form of a computer based train- 
ing program that must be successfully completed.

(cid:2) The creation of the position of Chief Security 

Officer, whose duties include the establishment 
and monitoring of procedures designed to safe- 
guard company and consumer data and prepare 
our enterprise to recover from virtually any 
unplanned business interruption.

(cid:2) While we have always conducted our business in 
compliance with the letter and spirit of laws man- 
dating equal opportunity, the company’s Core 
Values were modified last year to make it clearer 
that State Auto appreciates the importance of 
diversity or inclusion.
In addition, diversity training 
has been completed by senior management and it 
is being extended to other levels of management.

Robert H. Moone, retired president, 
CEO, and chairman of the board.

As many of you know, at the 2005 Annual

Shareholders Meeting, I announced my decision to
retire from this wonderful organization at the end of
the meeting this year. As a consequence, the
independent directors of your board – in concert
with the independent directors of State Auto Mutual
– have concluded a well-planned and highly suc-
cessful search. As we went to press with this
report, it was announced that Robert P. Restrepo,
Jr. will assume the leadership of State Auto. I know
that I am leaving STFC and the State Auto Group
in very capable hands. Bob is bright, energetic
and talented. And he knows the insurance busi-
ness. He was selected from a long list of outstand-
ing candidates, and under his leadership, STFC
will remain focused on continuing to serve our cus-
tomers and build value.

For my part, merely let me close with a heartfelt
thanks to all of you and to your designees on the
board for allowing me the opportunity to be a part
of this enterprise. And to the thousands of employ-
ees and agents with whom I have had the privilege
to work over a 36-year career, thanks for your sup-
port and your friendship.

Sincerely,

A tribute to State Auto
Financial Corporation’s
greatest assets

This ad appeared in publications throughout the
Company's operating territories as a tribute to the
2,040 employees who made State Auto Financial
Corporation Forbes magazine's choice as the 2006
"Best Managed" insurance company in America.
The candidates are pulled from the Forbes Platinum
400 list.  

In the response to the magazine's question,
“What sets you apart,” the Company responded,
"We're caring, friendly, hard-working, open, people-
oriented, generous, thoughtful…But we also know
our business and our industry."  A proven acquisi-
tion strategy and the ability to focus on the funda-
mentals were two other submitted attributes.  

The numbers mattered, too.  Forbes noted that
"Every year since its public offering in 1991, State
Auto's combined ratio…has beaten the industry
average by a wide margin."

Governance
continued from page 9

(cid:2) Governance structures provide a framework for 

the interactions among our board of directors and 
executive management. These interactions are 
directed toward compliance with the rules imposed 
on us by third parties as well as those we choose 
to impose on ourselves. We have regular execu- 
tive sessions of directors, board retreats, and a 
lead director. We also have  board committee 
charters, governance guidelines, and a code of  
business conduct, all of which are posted at 
www.stfc.com. These are reviewed annually and 
modified as deemed appropriate by the directors.
We have sponsored continuing education for our 
directors for two straight years and are planning a
third session in 2006.

The other element of governance that merits com-
ment relates to the relationship between the compa-
ny’s parent and the company. Almost two-thirds of
STFC’s common shares are owned by State Auto
Mutual, an Ohio domiciled mutual insurer. STFC is
somewhat different from many other public compa-
nies because it is not the company at the top of the
organization chart, the ultimate controlling person. In
almost every case, the interests of State Auto Mutual
and STFC are aligned because STFC represents
State Auto Mutual’s biggest investment and the
underwriting operations of each are essentially inter-
twined. Practically speaking, neither could operate
as it does today without the other. Both sides of the
house have been able to preserve the collegial
nature of our boards, with open, honest, good faith
communications which focus on serving the interests
of the constituency each serves, while recognizing
the part each company plays in the effective opera-
tion of the entire enterprise. That we have achieved
this is perhaps the best evidence of the quality of our
governance.

IMPORTANT INFORMATION REGARDING FORWARD-LOOKING STATEMENTS

All statements, other than statements of historical facts, included in this Annual Report on Form 10-K (this
“Form 10-K”) of State Auto Financial Corporation (“State Auto Financial” or “STFC”) or incorporated herein by
reference, including, without limitation, statements regarding State Auto Financial’s future financial position,
business strategy, budgets, projected costs, goals and plans and objectives of management for future operations,
are forward-looking statements within the meaning of the Private Securities Litigation Reform Act of 1995.
Forward-looking statements generally can be identified by the use of forward-looking terminology such as
“may,” “will,” “expect,” “intend,” “estimate,” “anticipate,” “project,” “believe” or “continue” or the negative
thereof or variations thereon or similar terminology. Forward-looking statements speak only as the date the
statements were made. Although State Auto Financial believes that the expectations reflected in forward-looking
statements have a reasonable basis, it can give no assurance that these expectations will prove to be correct.
Forward-looking statements are subject to risks and uncertainties that could cause actual events or results to
differ materially from those expressed in or implied by the statements. For a discussion of the most significant
risks and uncertainties that could cause State Auto Financial’s actual results to differ materially from those
projected, see “Risk Factors” in Item 1A of this Form 10-K. Except to the limited extent required by applicable
law, State Auto Financial undertakes no obligation to update or revise any forward-looking statements, whether
as a result of new information, future events or otherwise.

PART I

Item 1. Business

(a) General Development of Business

State Auto Financial is an Ohio property and casualty insurance holding company primarily engaged in
writing both personal and commercial
is
headquartered in Columbus, Ohio. State Auto Financial owns 100% of State Auto P&C, Milbank, Farmers, SA
Ohio, and SA National, each of which is a property and casualty insurance company.

lines of insurance. Incorporated in 1990, State Auto Financial

1

Mutual is an Ohio mutual property and casualty insurance company organized in 1921. Mutual owns
approximately 65% of State Auto Financial’s outstanding common shares. Mutual also owns 100% of SA Florida
and SA Wisconsin, each which is a property and casualty insurance company. Mutual also owns 100% of
Meridian Insurance Group, Inc. (“MIGI”), an insurance holding company. MIGI owns 100% of Meridian
Security, a property and casualty insurance company. In 2001, Mutual merged with Meridian Mutual Insurance
Company (“Meridian Mutual”), with Mutual continuing as the surviving corporation, and in a substantially
concurrent transaction Mutual acquired the outstanding shares of MIGI. MIGI is also a party to an affiliation
agreement with Meridian Citizens Mutual, a mutual property and casualty insurance company. Meridian Security
and Meridian Citizens Mutual are hereafter referred to collectively as the “MIGI Insurers” and together with
MIGI, the “MIGI Companies.”

State Auto Financial owns 100% of Stateco, which provides investment management services to affiliated
insurance companies. State Auto Financial also owns 100% of S.I.S., a developer and seller of insurance-related
software. State Auto P&C and Stateco are members of 518 PML, which owns and leases real and personal
property to affiliated companies. The results of the operations of S.I.S. and 518 PML are not material to the total
operations of State Auto Financial.

State Auto P&C has participated in a quota share reinsurance pooling arrangement with Mutual since 1987
(the “Pooling Arrangement”). Since January 1, 2005, the participants in the Pooling Arrangement have been
State Auto P&C, Mutual, Milbank, SA Wisconsin, Farmers, SA Ohio, SA Florida, Meridian Security and
Meridian Citizens Mutual. See “Narrative Description of Business - Pooling Arrangement” in this Item 1 for
further information regarding the Pooling Arrangement.

The State Auto Group writes a broad line of property and casualty insurance, such as standard personal and
commercial automobile, nonstandard personal automobile, homeowners and farmowners, commercial multi-
peril, workers’ compensation, general liability and fire insurance, through approximately 22,100 independent
insurance agents associated with approximately 3,050 agencies in 27 states. The Pooled Companies are rated A+
(Superior) by the A.M. Best Company.

(b) Financial Information about Segments

The Company currently operates in three segments: standard insurance, nonstandard insurance and
investment management services. Beginning January 1, 2006, the investment management services segment will
no longer be reported as a separate segment as the results of this segment no longer meet the quantitative
thresholds for separate presentation as a reportable segment even with consideration of aggregation of other
segments with similar economic characteristics, among other factors. Financial information about all these
segments is set forth in Note 15 to the Company’s Consolidated Financial Statements included in Item 8 of this
Form 10-K. Additional information regarding the Company’s insurance and noninsurance segments is provided
in “Narrative Description of Business.”

Property and Casualty Insurance

Pooling Arrangement

The Pooled Companies are parties to the Pooling Arrangement. Prior to 2005, the Pooling Arrangement was
governed by the reinsurance pooling agreement known as the “2000 Pooling Agreement,” which had been
amended from time to time. Since January 1, 2005, the Pooling Arrangement has been governed by the
reinsurance pooling agreement known as the “2005 Pooling Arrangement.” The Pooling Arrangement covers all
the property and casualty insurance written by the Pooled Companies except voluntary assumed reinsurance
written by Mutual, State Auto Middle Market Insurance (as defined in the 2005 Pooling Agreement) and
intercompany catastrophe reinsurance written by State Auto P&C. Under the Pooling Arrangement, each of the

2

Pooled Companies cedes premiums, losses and expenses on all of its business to Mutual, and Mutual in turn
cedes to each of the Pooled Companies a specified portion of premiums, losses and expenses based on each of
the Pooled Companies’ respective pooling percentages. Mutual then retains the balance of the pooled business.

The following table sets forth a chronology of the participants and their participation percentage changes

that have occurred in the Pooling Arrangement since January 1, 1994:

Time period is for the year ended December 31, unless otherwise noted.

As a result of the changes made to the pooling percentages in 2001, which resulted in the STFC Pooled
Companies having their percentage participation changed to 80% in the aggregate, it is not management’s current
intention to recommend an adjustment to the STFC Pooled Companies’ aggregate participation percentage in the
foreseeable future. Under revised procedures, management of each of the Pooled Companies would make
recommendations to a standing independent committee of the Board of Directors of both Mutual and STFC.
These independent committees would review and evaluate such factors as they deem relevant and recommend
any appropriate pooling change to the Board of Directors of both Mutual and STFC. The Pooling Arrangement is
terminable by any Pooled Company at any time after a 90-day notice or by mutual agreement of the Pooled
Companies. None of the Pooled Companies currently intends to terminate the Pooling Arrangement.

Under the terms of the Pooling Arrangement, all premiums, incurred losses, loss expenses and other
underwriting expenses are prorated among the Pooled Companies on the basis of their participation in the pool.
By spreading the underwriting risk among each of the Pooled Companies, the Pooling Arrangement is designed

3

to produce more uniform and stable underwriting results for each of the Pooled Companies than any one
company would experience individually. One effect of the Pooling Arrangement is to provide each Pooled
Company with an identical mix of pooled property and casualty insurance business on a net basis.

The 2005 Pooling Agreement contains (and the 2000 Pooling Agreement contained) a provision excluding
catastrophic losses and loss adjustment expenses incurred by the Pooled Companies in the amount of $100.0
million in excess of $120.0 million, as well as the premium for such exposures. State Auto P&C reinsures each
insurer in the State Auto Group for this layer of reinsurance under a Catastrophe Assumption Agreement (defined
below). No losses were paid by State Auto P&C under the Catastrophe Assumption Agreement in 2005, 2004 or
2003. See “Narrative Description of Business—Reinsurance” in this Item 1 for further information regarding the
Catastrophe Assumption Agreement.

Nonstandard Auto Insurance

The Company writes nonstandard auto insurance through SA National. Nonstandard auto insurance covers
risks that are not considered “standard.” Nonstandard automobile programs provide insurance for private
passenger automobile risks that are typically rejected or cancelled by other insurance companies because the
risks have above average loss experience, a higher degree of hazard or a higher loss frequency potential than
standard risks. This business is not part of the Pooling Arrangement. See “Narrative Description of Business—
Marketing” and “Reportable Segments” in this Item 1 for further information regarding the Company’s
nonstandard auto insurance business.

Management Agreement

State Auto P&C’s employees provide all organizational, operational and management functions for all
insurance affiliates within the State Auto Group through management and cost sharing agreements. Mutual
provides facilities for all the insurance affiliates under the same management and cost sharing agreements. A
management and operations agreement, hereafter referred to as the “2005 Management Agreement,” is in place
among State Auto P&C, Mutual, State Auto Financial, Milbank, Farmers, SA Ohio, SA National, MIGI
Companies, Stateco, S.I.S. and 518 PML. The 2005 Management Agreement is a cost sharing agreement. A
management agreement, hereafter referred to as the “2000 Midwest Management Agreement” is in place among
State Auto P&C, Mutual and SA Wisconsin. For the performance of its services under the 2000 Midwest
Management Agreement, SA Wisconsin pays State Auto P&C a quarterly management and operations services
fee of 0.75% of direct written premium. A separate cost sharing agreement is in place among State Auto P&C,
Mutual and SA Florida.

Each of the affiliated management and cost sharing agreements has a ten-year term and automatically
renews for an additional ten-year period unless sooner terminated in accordance with its terms. If the 2005
Management Agreement would be terminated for any reason, the Company would have to re-locate its facilities
to continue its operations. However, State Auto Financial does not currently anticipate the occurrence of a
termination of the 2005 Management Agreement.

Reportable Segments

See Note 15, Reportable Segments, of the Notes to the Company’s Consolidated Financial Statements

included in Item 8 of this Form 10-K and Item 7 of this Form 10-K.

Marketing

Having recently commenced operations in Arizona, the State Auto Group markets its products in 27 states,
through approximately 22,100 insurance agents associated with approximately 3,050 independent insurance
agencies. None of the companies in the State Auto Group has any contracts with managing general agencies.

4

SA National markets nonstandard products in 22 states exclusively through the Company’s network of

independent agents.

Because independent insurance agents can significantly influence which insurance company their customers
select, management views the Company’s independent insurance agents as its primary customers. Management
strongly supports the independent agency system and believes that maintenance of a strong agency system is
essential for the Company’s present and future success. As such, the Company continually develops programs
and procedures to enhance agency relationships, including the following: regular travel by senior management
and branch office staff to meet with agents, in person, in their home states; training opportunities; travel
incentives related to profit and growth; sharing a portion of the underwriting profit generated by the agent’s book
of business; and an agent stock purchase plan.

The Company actively helps its agencies develop professional sales skills within their staffs. The training
programs include both products and sales training in concentrated programs conducted in the Company’s home
office. Further, the training programs include disciplined follow-up and coaching for an extended time. Other
targeted training sessions are held in the Company’s branch office locations from time to time.

The Company has made continuing efforts to use technology to make it easier for its agents to do business
with the Company. The Company offers internet-based (i) rating, (ii) policy application submission and
(iii) execution of endorsements for certain products. In addition, the Company provides its agents with the
opportunity to maintain policyholder records electronically, avoiding the expense of preparing and storing paper
records. Software developed by S.I.S. also enhances the ability of the Company and its agents to take advantage
of electronic data submission. The Company believes that, since agents and their customers realize better service
and efficiency through automation, they value their relationship with the Company. Automation can make it
easier for the agent to do business with the Company, which attracts prospective agents and enhances the existing
agencies’ relationships with the Company.

The Company shares the cost of approved advertising with selected agencies. The Company provides agents
with certain travel and cash incentives if they achieve certain sales and underwriting profit levels. Further, the
Company recognizes its very top agencies—measured by consistent profitability, achievement of written
premium thresholds and growth—as Inner Circle Agencies. Inner Circle Agencies are rewarded with additional
trip and financial incentives, including additional profit sharing bonus and additional contributions to their Inner
Circle Agent Stock Purchase Plan, a part of the Agent Stock Purchase Plan described below.

To strengthen agency commitment

to producing profitable business and further develop its agency
relationships, the Company’s Agent Stock Purchase Plan offers its agents the opportunity to use commission
income to purchase the Company’s stock. The Company’s transfer agent administers the plan using commission
dollars assigned by the agents to purchase shares on the open market through a stockbroker. The Company also
makes available to certain top performing agents the opportunity to vest grants of options in the Company’s
common shares provided the participants meet performance targets described in the Agent Stock Option Plan.

The Company receives premiums on products marketed in Alabama, Arizona, Arkansas, Florida, Georgia,
Illinois, Indiana, Iowa, Kansas, Kentucky, Maryland, Michigan, Minnesota, Mississippi, Missouri, North
Carolina, North Dakota, Ohio, Oklahoma, Pennsylvania, South Carolina, South Dakota, Tennessee, Utah,
Virginia, West Virginia and Wisconsin. During 2005, the seven states that contributed the greatest percentage of
the Company’s direct premiums written were as follows: Ohio (17.8%), Kentucky (11.0%), Indiana (7.6%),
Tennessee (6.7%), Minnesota (6.0%), Pennsylvania (5.1%) and Maryland (4.9%).

Claims

Insurance claims on policies written by the Company are usually investigated and settled by staff claims
adjusters. The Company’s claims division emphasizes timely investigation of claims, settlement of meritorious

5

claims for equitable amounts, maintenance of adequate case reserves for claims, and control of external claims
adjustment expenses. Achievement of these goals supports the Company’s marketing efforts by providing agents
and policyholders with prompt and effective service.

Claim settlement authority levels are established for each adjuster, supervisor and manager based on his or
her level of expertise and experience. The claims division is responsible for reviewing the claim, obtaining
necessary documentation and establishing loss and expense reserves of certain claims. Generally, property or
casualty claims estimated to reach $150,000 or above are sent to the home office to be supervised by claims
division specialists. Branches with small volumes of large claims report claims to the home office at a lower
dollar threshold. In territories in which there is not sufficient volume to justify having full-time adjusters, the
Company uses independent appraisers and adjusters to evaluate and settle claims under the supervision of claims
division personnel.

The Company attempts to minimize claims adjusting costs by settling as many claims as possible through its
internal claims staff and, if possible, by settling disputes regarding automobile physical damage and property
insurance claims (first party claims) through arbitration. In addition, selected agents have authority to settle small
first party claims, which improves claims service.

Claim representatives use third party, proprietary bodily injury evaluation software to help them value
bodily injury claims, except for the most severe injury cases. This software continues to be a valuable tool for the
Company. The Claims Contact Centers allow the Company to improve claims efficiency and economy by
concentrating the handling of smaller, less complex claims in a centralized environment. The Company provides
24 hour, seven days a week claim service, either through associates in the Claims Contact Centers, which are
located in Des Moines, Iowa and Columbus, Ohio, or, for a few overnight hours, through a third party service
provider.

Reserves

Loss reserves are management’s best estimates at a given point in time of what the Company expects to pay
in claims, based on facts, circumstances and historical trends then known. During the loss settlement period,
additional facts regarding individual claims may become known, and consequently it often becomes necessary to
refine and adjust the estimates of liability. The Company’s results of operations and financial condition could be
impacted, perhaps significantly, in the future if the ultimate payments required to settle claims vary from the
liability currently recorded.

The Company maintains reserves for the eventual payment of losses and loss expenses for both reported
claims and incurred claims that have not yet been reported. Loss expense reserves are intended to cover the
ultimate costs of settling all losses, including investigation, litigation and in-house claims processing costs from
such losses.

Reserves for reported losses are initially established on either a case-by-case or formula basis depending on
the type and circumstances of the loss. The case-by-case reserve amounts are determined based on the
Company’s reserving practices, which take into account the type of risk, the circumstances surrounding each
claim and policy provisions relating to types of loss. The formula reserves are based on historical paid loss data
for similar claims with provisions for trend changes caused by inflation. Loss and loss expense reserves for
incurred claims that have not yet been reported are estimated based on many variables including historical and
legal developments, storm loss estimates and
statistical
economic conditions. Case and formula basis loss reserves are reviewed on a regular basis. As new data becomes
available, estimates are updated resulting in adjustments to loss reserves. Generally, reported losses initially
reserved on a formula basis which have not settled after six months, are case reserved at that time. Although
management uses many resources to calculate reserves, there is no precise method for determining the ultimate
loss reserves for financial statement purposes. For additional
liability. The Company does not discount

information, changes in exposure units, inflation,

6

information regarding the Company’s reserves, see Item 7 of this Form 10-K, “Management, Discussion and
Analysis of Financial Condition and Results of Operations—Loss Reserves.”

Mutual has guaranteed the adequacy of State Auto P&C’s loss and loss expense reserves as of December 31,
1990. Pursuant to the guarantee, Mutual has agreed to reimburse State Auto P&C for any losses and loss
expenses in excess of State Auto P&C’s December 31, 1990 reserves ($65.5 million) that may develop from
claims that have occurred on or prior to that date. This guarantee ensures that any deficiency in the reserves of
State Auto P&C as of December 31, 1990, under the Pooling Arrangement percentages effective on
December 31, 1990 will be reimbursed by Mutual. As of December 31, 2005, there has been no adverse
development of these reserves. In the event Mutual becomes financially impaired, and subject to regulatory
restrictions, it may be unable to make any such reimbursement.

The following table presents one-year development information on changes in the reserve for loss and loss

expenses of the Company for each of the three years in the period ended December 31, 2005:

Includes amounts due from affiliates of $5.7 million, $5.7 million and $4.3 million in 2005, 2004 and 2003, respectively.
Includes net amounts assumed from affiliates of $296.9 million, $303.9 million and $304.0 million in 2005, 2004 and 2003, respectively.
This line item shows decreases in the current calendar year in the provision for losses and loss expenses attributable to claims occurring
in prior years. The decrease of $44.3 million, $22.2 million and $1.8 million in 2005, 2004 and 2003, respectively, for claims occurring
in prior years is well within normal expectations for reserve development and claim settlement uncertainty. See Note 4 to the Company’s
Consolidated Financial Statements included in Item 8 of this Form 10-K.
Includes amounts due from affiliates of $5.5 million in 2005 and $5.7 million in both 2004 and 2003.
Includes net amounts assumed from affiliates of $302.6 million, $296.9 million and $303.9 million in 2005, 2004 and 2003, respectively.

The following table sets forth the development of reserves for losses and loss expenses from 1995 through
2005 for the Company. “Net liability for losses and loss expenses payable” sets forth the estimated liability for
unpaid losses and loss expenses recorded at the balance sheet date, net of reinsurance recoverables, for each of
the indicated years. This liability represents the estimated amount of losses and loss expenses for claims arising
in the current and all prior years that are unpaid at the balance sheet date, including losses incurred but not
reported to the Company.

7

The lower portion of the table shows the re-estimated amounts of the previously reported reserve based on
experience as of the end of each succeeding year. The estimate is increased or decreased as more information
becomes known about the claims incurred.

The upper section of the table shows the cumulative amounts paid with respect to the previously reported
reserve as of the end of each succeeding year. For example, through December 31, 2005, the Company had paid
81.6% of the currently estimated losses and loss expenses that had been incurred, but not paid, as of
December 31, 1996.

The amounts on the “cumulative redundancy (deficiency)” line represent the aggregate change in the
estimates over all prior years. For example, the 1996 calendar year reserve has developed a $1.0 million or 0.5%
redundancy through December 31, 2005. That amount has been included in operations over the ten years and did
not have a significant effect on income in any one year. The effects on income caused by changes in estimates of
the reserves for losses and loss expenses for the most recent three years are shown in the foregoing three-year
loss development table.

In evaluating the information in the table, it should be noted that each amount includes the effects of all
changes in amounts for prior periods. For example, the amount of the redundancy related to losses settled in
1998, but incurred in 1995, will be included in the cumulative redundancy amount for years 1996, 1997 and
1998. The table does not present accident or policy year development data, which readers may be more
accustomed to analyzing. Conditions and trends that have affected the development of the liability in the past
may not necessarily occur in the future. Accordingly, it may not be appropriate to extrapolate future redundancies
or deficiencies based on this table.

In 1995, 1998, 1999, 2000 and 2001 the Pooling Arrangement was amended to increase the Company’s
share of premiums, losses and expenses and in 2005 to add the business of the Meridian Insurers. An amount of
assets equal to the increase in net liabilities was transferred to the Company from Mutual in 1995, 1998, 1999,
2000 and 2001 in conjunction with each year’s respective pooling change and in 2005 from the Meridian
Insurers. The amount of the assets transferred in 1995, 1998, 1999, 2000, 2001 and 2005 has been netted against
and has reduced the cumulative amounts paid for years prior to 1995, 1998, 1999, 2000, 2001 and 2005,
respectively.

Reinsurance

Members of the State Auto Group follow the customary industry practice of reinsuring a portion of their
exposures and paying to the reinsurers a portion of the premiums received. Insurance is ceded principally to
reduce net liability on individual risks or for individual loss occurrences, including catastrophic losses. Although
reinsurance does not legally discharge the individual members of the State Auto Group from primary liability for
the full amount of limits applicable under their policies, it does make the assuming reinsurer liable to the extent
of the reinsurance ceded.

Each member of the State Auto Group is party to working reinsurance treaties for property, casualty and
workers’ compensation lines with several reinsurers arranged through a reinsurance intermediary. Under the
property per risk excess of loss treaty, each member is responsible for the first $2.0 million of each covered loss,
and the reinsurers are responsible for 100% of the excess over $2.0 million up to $10.0 million of covered loss.
The rates for this reinsurance are negotiated annually.

The terms of the casualty excess of loss program provide that each company in the State Auto Group is
responsible for the first $2.0 million of a covered loss. The reinsurers are responsible for 90% of the excess over
$2.0 million up to $5.0 million of covered loss. Also, certain unusual claim situations involving bodily injury
liability, property damage, uninsured motorist and personal injury protection are covered by an arrangement that
provides for $10.0 million of coverage in excess of a $5.0 million retention for each loss occurrence. This layer
of reinsurance sits above the $3.0 million excess of $2.0 million arrangement. The rates for this reinsurance are
negotiated annually.

The terms of the workers’ compensation excess of loss program provide that each company in the State
Auto Group is responsible for the first $2.0 million of covered loss. The reinsurers are responsible for 100% of
the excess over $2.0 million up to $10.0 million of covered loss. Net retentions under this contract may be
submitted to the casualty excess of loss program, subject to a limit of $2.0 million per loss occurrence. The rates
for this reinsurance are negotiated annually.

In addition to the workers’ compensation reinsurance program described above, each company in the State
Auto Group is party to an agreement which provides an additional layer of excess of loss reinsurance for
workers’ compensation losses involving multiple workers. Subject to $10.0 million of retention, reinsurers are
responsible for 100% of the excess over $10.0 million up to $20.0 million of covered loss. This coverage is
subject to a “Maximum Any One Life” limit of $10.0 million. The rates for this reinsurance are negotiated
annually.

In addition, the State Auto Group has secured other reinsurance to limit the net cost of large loss events for
certain types of coverage. Included are umbrella liability losses which are reinsured up to a limit of $10.0 million
with a maximum $0.6 million retention. The State Auto Group also makes use of facultative reinsurance for
unique risk situations and participates in involuntary pools and associations in certain states.

The State Auto Group participates in an intercompany catastrophe reinsurance program (the “Catastrophe
Assumption Agreement”). Under this program, the members of the State Auto Group, on a combined basis,
retain the first $40.0 million of catastrophe losses that affect at least two individual risks. For catastrophe losses
incurred by the State Auto Group up to $80.0 million, in excess of $40.0 million, traditional reinsurance coverage
is provided with a co-participation of 5%. For catastrophe losses incurred by the State Auto Group up to $100.0
million, in excess of $120.0 million, in exchange for a premium paid by each reinsured company, State Auto
P&C acts as the catastrophe reinsurer for the State Auto Group under the terms of the Catastrophe Assumption
Agreement. There have been no losses assumed under this agreement.

In November 2005, State Auto Financial entered into a Credit Agreement (the “Credit Agreement”) with a
financial institution and a syndicate of other lenders to provide for a $100.0 million five-year unsecured
revolving credit facility (the “Credit Facility”). During the term of the Credit Facility, State Auto Financial has
the right to increase the total facility amount by $25.0 million, up to a maximum total facility amount of
$125.0 million, provided that no event of default has occurred and is continuing. The Credit Facility is available
for general corporate purposes, including working capital and acquisitions, and for catastrophic loss purposes. At
the present time, the Company intends to use the Credit Facility for catastrophe loss purposes. The Credit Facility

10

replaced a credit agreement (the “Old Credit Agreement”) between a STFC special purpose company and a
syndicate of lenders which expired on November 9, 2005. The Credit Facility provides the Company with greater
flexibility than the Old Credit Agreement. The Old Credit Agreement and related agreements were part of a
structured contingent financing arrangement which provided State Auto Financial with up to $100.0 million of
funding for reinsurance purposes if the State Auto Group incurred catastrophe losses in excess of $120.0 million.
See Item 7 of this Form 10-K, “Management’s Discussion and Analysis of Financial Condition and Results of
Operations—Liquidity and Capital Resources,” for additional information regarding the New Credit Agreement
and the Old Credit Agreement.

As of July 1, 2005, SA National and Mutual terminated their reinsurance agreement. While this reinsurance
agreement was in effect, Mutual assumed up to $4.9 million of each liability loss occurrence in excess of SA
National’s $50,000 of retention and up to $0.5 million of each catastrophe loss occurrence in excess of SA
National’s $50,000 of retention. Mutual also provided SA National with an 8.5% quota share within the $50,000
retention on liability coverages and a 20% quota share on physical damage coverages. SA National and Mutual
mutually agreed to terminate the reinsurance agreement because of SA National’s stronger surplus position,
relative to the commencement date of the agreement, which makes it more efficient for SA National to retain
such exposures rather than to reinsure them. Under the terms of the termination, Mutual will continue to be
liable, with respect to policies in force at the termination date, for occurrences until the expiration, cancellation or
next anniversary, not to exceed one year.

See “Narrative Description of Business—Regulation” of this Item 1 for a discussion of the Terrorism Risk
Insurance Act of 2002 (the “TRIA”) and its successor, the Terrorism Risk Insurance Extension Act of 2005
(“TRIEA”) (collectively, the “Terrorism Acts”).

Regulation

Most states, including all the domiciliary states of the State Auto Group, have enacted legislation that
regulates insurance holding company systems. Each insurance company in the holding company system is
required to register with the insurance supervisory agency of its state of domicile and furnish information
concerning the operations of companies within the holding company system that may materially affect the
operations, management or financial condition of the insurers within the system. Pursuant to these laws, the
respective insurance departments may examine any members of the State Auto Group, at any time, require
disclosure of material transactions involving insurer members of the holding company system, and require prior
notice and an opportunity to disapprove of certain “extraordinary” transactions, including, but not limited to,
extraordinary dividends to shareholders. Pursuant to these laws, all transactions within the holding company
system affecting any members of the State Auto Group must be fair and equitable. In addition, approval of the
applicable Insurance Commissioner is required prior to the consummation of transactions affecting the control of
an insurer. The insurance laws of all the domiciliary states of the State Auto Group provide that no person may
acquire direct or indirect control of a domestic insurer without obtaining the prior written approval of the state
insurance commissioner for such acquisition.

In addition to being regulated by the insurance department of its state of domicile, each insurance company
is subject to supervision and regulation in the states in which it transacts business. Such supervision and
regulation relate to numerous aspects of an insurance company’s business operations and financial condition. The
primary purpose of such supervision and regulation is to ensure financial stability of insurance companies for the
protection of policyholders. The laws of the various states establish insurance departments with broad regulatory
powers relative to granting and revoking licenses to transact business, regulating trade practices, licensing agents,
approving policy forms, setting reserve requirements, determining the form and content of required statutory
financial statements, prescribing the types and amount of investments permitted and requiring minimum levels of
statutory capital and surplus. Although premium rate regulation varies among states and lines of insurance, such
regulations generally require approval of the regulatory authority prior to any changes in rates. In addition, all of
the states in which the State Auto Group transacts business have enacted laws which restrict these companies’

11

underwriting discretion. Examples of these laws include restrictions on policy terminations, restrictions on
agency terminations and laws requiring companies to accept any applicant for automobile insurance. These laws
may adversely affect the ability of the insurers in the State Auto Group to earn a profit on their underwriting
operations.

Insurance companies are required to file detailed annual reports with the supervisory agencies in each of the
states in which they do business, and their business and accounts are subject to examination by such agencies at
any time.

There can be no assurance that such regulatory requirements will not become more stringent in the future

and have an adverse effect on the operations of the State Auto Group.

Dividends. STFC’s insurance subsidiaries generally are restricted by the insurance laws of their respective
states of domicile as to the amount of dividends they may pay to STFC without the prior approval of the
respective state regulatory authorities. Generally, the maximum dividend that may be paid by an insurance
subsidiary during any year without prior regulatory approval is limited to the greater of a stated percentage of
that subsidiary’s statutory surplus as of a certain date, or adjusted net income of the subsidiary for the preceding
year. Under current law, a total of $121.2 million is available for payment to State Auto Financial as a dividend
from State Auto P&C, Milbank, Farmers, SA Ohio and SA National during 2006, less dividend payments made
in the previous twelve month period without prior approval from their respective domiciliary state insurance
departments. State Auto Financial received dividends of $40.5 million and $12.0 million from its insurance
subsidiaries in 2005 and 2004, respectively.

Rate and Related Regulation. In general, the Company is not aware of the adoption of any adverse
legislation or regulation by any state where the Company did business during 2005 which would present material
obstacles to the Company’s overall business. However, several states where the Company does business have
passed or are considering more strict regulation of the use of credit scoring in rating and/or risk selection in
personal lines of business. Similarly, several states are considering restricting insurers’ rights to use loss history
information maintained in various databases by insurance support organizations. These tools help the Company
price its products more fairly and enhance its ability to compete for business that it believes will be profitable.
Such regulations would limit the ability of the Company, as well as the ability of all other insurance carriers
operating in any affected jurisdiction, to take advantage of these tools. Insurer use of credit scores is also being
studied by the Federal Trade Commission, as respects whether or not credit scoring has a disparate impact on
protected classes. The results of this study, which have not been published as of the filing of this Form 10-K,
could affect the industry’s use of this tool.

In an attempt to make capital and surplus requirements more accurately reflect the underwriting risk of
different lines of insurance, as well as investment risks that attend insurers’ operations, the National Association
requirements. As of
of
December 31, 2005, each insurer affiliated with the Company surpassed all standards tested by the formula
applying risk-based capital requirements.

Insurance Commissioners (“NAIC”) annually tests insurers’

risk-based capital

The property and casualty insurance industry is also affected by court decisions. In general, premium rates
are actuarially determined to enable an insurance company to generate an underwriting profit. These rates
contemplate a certain level of risk. The courts may modify, in a number of ways, the level of risk which insurers
had expected to assume, including eliminating exclusions, expanding the terms of the contract, multiplying limits
of coverage, creating rights for policyholders not intended to be included in the contract and interpreting
applicable statutes expansively to create obligations on insurers not originally considered when the statute was
passed. Courts have also undone legal reforms passed by legislatures, which reforms were intended to reduce a
litigant’s rights of action or amounts recoverable and so reduce the costs borne by the insurance mechanism.
These court decisions can adversely affect an insurer’s profitability. They also create pressure on rates charged
for coverages adversely affected, and this can cause a legislative response resulting in rate suppression that can
adversely affect an insurer.

12

The Terrorism Acts require the federal government and the insurance industry to share in insured losses up
to $100 billion per year resulting from future terrorist attacks within the United States. Under the Terrorism Acts,
commercial property and casualty insurers must offer their commercial policyholders coverage against certified
acts of terrorism, but the policyholders may choose to reject this coverage. If the policyholder rejects coverage
for certified acts of terrorism, the Company intends, subject to the approval of the state regulators, to cover only
such acts of terrorism that are not certified acts under Terrorism Acts and that do not arise out of nuclear,
biological or chemical agents. In December 2005, Congress enacted the TRIEA, which extended TRIA, with
some modifications, for two years beyond TRIA’s sunset date of December 31, 2005. This law removed the
mandate to offer terrorism coverage for five lines of business: commercial auto, burglary and theft, surety,
professional liability and farmowners multiple peril. In addition, TRIEA had the effect of increasing insurers’
deductible and co-pay percentages under this federal program. The Company’s current property reinsurance
treaties exclude certified acts of terrorism. If the Terrorism Acts expire in two years, those treaties may be
revised to exclude acts of terrorism as defined within the treaties. Likewise, if the Terrorism Acts expire at the
end of the current extension, the Company may pursue changes to its direct commercial policies to exclude acts
of terrorism as defined within its policies.

An area of regulatory focus in late 2004 and throughout 2005, and which may continue to receive additional
is “producer compensation arrangements.” The New York Attorney General undertook
focus in 2006,
investigations and initiated lawsuits involving allegations of improper compensation arrangements between
brokers and insurance companies. These actions have led several state insurance departments to initiate their own
surveys or inquiries into the activities of their domestic insurers with respect
to producer compensation
arrangements in their respective states. Two state insurance departments have delivered inquiries to the
Company, and the Company has responded to each of the inquiries. It is the Company’s understanding that these
inquiries are part of an overall fact-finding process initiated by these state insurance departments, and that similar
inquiries were made to a number of other domestic insurers in these states. The inquiries did not indicate or
imply that the Company had done anything improper with respect to its compensation arrangements with its
agents. The improper producer compensation arrangements generally involve insurance brokers, which are
persons retained and compensated by the insurance customer. The Company markets its insurance products
through independent insurance agents who have been appointed to act on the Company’s behalf, and the
Company, not the insurance customer, compensates these agents pursuant to contractual arrangements. Under its
agency agreements, the Company’s compensation arrangements with its agencies consist of commissions paid
for the sale of the Company’s insurance products, usually based upon a percentage of the premium paid by the
insurance customer, and a “contingent commission.” This “contingent commission” is based upon the
underwriting profit generated by that agency’s book of business placed with the State Auto Group. Like many
other sales organizations, the Company also offers sales incentives to its agencies. The Company believes that its
agent compensation arrangements are in compliance with the law and consistent with good business practices.

Investments

The Company’s investment portfolio is managed to provide growth of statutory surplus in order to facilitate
increased premium writings over the long term while maintaining the ability to service current insurance
operations. The primary objectives are to generate income, preserve capital and maintain liquidity. The
Company’s investment portfolio is managed separately from that of Mutual and its subsidiaries, and investment
results are not shared by the Pooled Companies through the Pooling Arrangement. Stateco performs investment
management services for
the Company and Mutual and its subsidiaries, although investment policies
implemented by Stateco continue to be set for each company through the Investment Committee of its Board of
Directors.

The Company’s decision to make a specific investment is influenced primarily by the following factors:
(a) investment risks; (b) general market conditions; (c) relative valuations of investment vehicles; (d) general
market interest rates; (e) the Company’s liquidity requirements at any given time; and (f) the Company’s current
federal income tax position and relative spread between after tax yields on tax-exempt and taxable fixed income

13

to purchasing fixed income
investments. The Company has investment policy guidelines with respect
investments for the insurance subsidiaries which preclude investments in bonds that are rated below investment
grade by a recognized rating service. The maximum investment in any single note or bond is limited to 5.0% of
statutory assets, other than obligations of the U.S. government or government agencies, for which there is no
limit. Investments in equity securities are selected based on their potential for appreciation as well as ability to
continue paying dividends. See Item 7 of this Form 10-K, “Management’s Discussion and Analysis of Financial
Condition and Results of Operations—Other—Investments, Market Risks,” for a discussion regarding the market
risks related to the Company’s investment portfolio.

The Company’s fixed maturity investments are classified as available-for-sale and carried at fair market
value, according to the Financial Accounting Standards Board (“FASB”) Statement 115, “Accounting for Certain
Investments in Debt and Equity Securities” (“SFAS 115”).

The Company’s Investment Policy and Guidelines permit investment in debt issues rated A or better by two
major rating services. The Company’s fixed maturities portfolio is composed of high quality, investment grade
issues, comprised almost entirely of debt issues rated AAA or AA. As of December 31, 2005 and 2004, the bond
portfolio had a fair market value that totaled $1,617.3 million and $1,502.1 million, respectively.

At December 31, 2005 and 2004, the Company’s equity portfolio is classified as available-for-sale and

carried at fair market value that totaled $255.6 million and $193.6 million, respectively.

this Form 10-K,
“Management’s Discussion and Analysis of Financial Condition and Results of Operations—Other—
Investments.”

Competition

The property and casualty insurance industry is highly competitive. The Company competes with numerous
insurance companies, many of which are substantially larger and have considerably greater financial resources.
In addition, because the Company’s products are marketed exclusively through independent insurance agencies,
most of which represent more than one company, the Company faces competition within each agency. See
“Narrative Description of Business – Marketing” in Item 1 of this Form 10-K. The Company competes through
underwriting criteria, appropriate pricing, quality service to the policyholder and the agent, and a fully developed
agency relations program.

Employees

As of February 28, 2006, the Company had 2,087 employees. Employees of the Company are not covered
by any collective bargaining agreement. Management of the Company considers its relationship with its
employees to be excellent.

Item 1A. Risk Factors

Statements contained in this Form 10-K may be “forward-looking” within the meaning of the Private
Securities Litigation Reform Act of 1995. Such forward-looking statements are subject to certain risks and
uncertainties that could cause State Auto Financial’s operating results to differ materially from those projected.
The following factors, among others, in some cases have affected, and in the future could affect, State Auto
Financial’s actual financial performance. The terms “State Auto Financial,” “STFC,” “our company,” “we,” “us”
and “our” as used in this discussion refer to State Auto Financial Corporation and its consolidated subsidiaries.

RESERVES

If our estimated liability for losses and loss expenses is incorrect, our reserves may be inadequate to cover

our ultimate liability for losses and loss expenses and may have to be increased.

We establish and carry, as a liability, reserves based on actuarial estimates of how much we will need to pay
in the future for claims incurred as of the end of the accounting period. We maintain loss reserves to cover our
estimated ultimate unpaid liability for losses and loss expenses with respect to reported and unreported claims
incurred as of the end of each accounting period. Reserves do not represent an exact calculation of liability, but
instead represent estimates, generally using actuarial projection techniques at a given accounting date. These
reserve estimates are expectations of what the ultimate settlement and administration of claims will cost based on
our assessment of facts and circumstances then known, review of historical settlement patterns, estimates of
trends in claims severity and frequency, legal theories of liability and other factors. Variables in the reserve
estimation process can be affected by both internal and external events, such as changes in claims handling
procedures, trends in loss costs, economic inflation, legal trends and legislative changes. Many of these items are
not directly quantifiable, particularly on a prospective basis. Additionally, there may be a significant reporting
lag between the occurrence of an insured event and the time it is actually reported to the insurer. We refine
reserve estimates in a regular ongoing process as historical loss experience develops and additional claims are
reported and settled. We record adjustments to reserves in the results of operations for the periods in which the
estimates are changed. In establishing reserves, we take into account estimated recoveries for reinsurance and
salvage and subrogation.

Because estimating reserves is an inherently uncertain process, currently established reserves may not be
adequate. If we conclude the estimates are incorrect and our reserves are inadequate, we are obligated to increase
our reserves. An increase in reserves results in an increase in losses and a reduction in our net income for the
period in which the deficiency in reserves is identified. Accordingly, an increase in reserves could have a
material adverse effect on our results of operations, liquidity and financial condition.

CATASTROPHE LOSSES

The occurrence of catastrophic events could materially reduce our profitability.

Our insurance operations expose us to claims arising out of catastrophic events. We have experienced, and
will in the future experience, catastrophe losses that may cause substantial volatility in our financial results for

17

any fiscal quarter or year and could materially reduce our profitability or harm our financial condition. Our
ability to write new business also could be affected. Catastrophes can be caused by various natural events,
including hurricanes, hailstorms, windstorms, earthquakes, severe winter weather and fires, none of which are
within our control. Catastrophe losses can vary widely and could significantly exceed our recent unprecedented
results. The frequency and severity of catastrophes are inherently unpredictable.

The extent of losses from a catastrophe is a function of both the total amount of insured exposure in the area
affected by the event and the severity of the event. Most catastrophes are restricted to small geographic areas;
however, hurricanes and earthquakes may produce significant damage in larger areas, especially those that are
heavily populated. Although catastrophes can cause losses in a variety of our property and casualty lines, most of
our catastrophe claims in the past have related to homeowners, other personal lines, allied lines and commercial
multi peril coverages. The geographic distribution of our business subjects us to catastrophe exposure from
hailstorms and earthquakes in the Midwest as well as catastrophe exposure from hurricanes in Florida and the
Gulf Coast, southern coastal states and Mid-Atlantic regions. In the last five years, the largest catastrophe or
series of catastrophes to affect our results of operations in any one year occurred in: 2005 with losses from
hurricanes Katrina and Wilma resulting in approximately $41.7 million in pre-tax losses; 2004 with losses from
hurricanes Charley, Frances, Jean and Ivan resulting in approximately $39.6 million in pre-tax losses; and 2003
when tornadoes, hailstorms and windstorms caused damage in 17 of our operating states resulting in
approximately $39.2 million in pre-tax losses.

We believe that increases in the value and geographic concentration of insured property and the effects of
inflation could increase the severity of claims from catastrophic events in the future. In addition, states have from
time to time passed legislation that has the effect of limiting the ability of insurers to manage catastrophe risk,
such as legislation prohibiting insurers from withdrawing from catastrophe-prone areas. Although we attempt to
reduce the impact on our business of a catastrophe by controlling concentrations of values in catastrophe prone
areas and through the purchase of reinsurance covering various categories of catastrophes, reinsurance may prove
inadequate if a major catastrophic loss exceeds the reinsurance limit, or an insurance subsidiary incurs a number
of smaller catastrophes that, individually, fall below the subsidiary’s retention level.

UNDERWRITING

Our success depends primarily on our ability to underwrite risks effectively and to charge adequate rates

to policyholders.

Our financial condition, cash flows and results of operations depend on our ability to underwrite and set
rates accurately for a full spectrum of risks, across a number of lines of insurance. Rate adequacy is necessary to
generate sufficient premium to pay losses, loss adjustment expenses and underwriting expenses and to earn a
profit.

Our ability to underwrite and set rates effectively is subject to a number of risks and uncertainties,

including, without limitation:

•

•

•

•

•

•

the availability of sufficient, reliable data;

our ability to conduct a complete and accurate analysis of available data;

our ability to timely recognize changes in trends and to project both the severity and frequency of losses
with reasonable accuracy;

uncertainties which are generally inherent in estimates and assumptions;

our ability to project changes in certain operating expense levels with reasonable certainty;

the development,
methodologies;

selection and application of appropriate rating formulae or other pricing

18

•

•

•

•

•

•

•

•

•

•

our ability to innovate with new pricing strategies, and the success of those innovations on
implementation;

our ability to predict policyholder retention accurately;

unanticipated court decisions, legislation or regulatory action;

unanticipated changes in our claim settlement practices;

changing driving patterns for auto exposures; changing weather patterns for property exposures;

changes in the medical sector of the economy;

unanticipated changes in auto repair costs, auto parts prices and used car prices;

impact of inflation and other factors on cost of construction materials and labor;

our ability to monitor property concentration in catastrophe prone areas, such as hurricane, earthquake
and wind/hail regions; and

the general state of the economy in the states in which we operate.

Such risks may result in our rates being based on inadequate or inaccurate data or inappropriate assumptions
or methodologies, and may cause our estimates of future changes in the frequency or severity of claims to be
incorrect. As a result, we could under price risks, which would negatively affect our margins, or we could
overprice risks, which could reduce our volume and competitiveness. In either event, our operating results,
financial condition and cash flows could be materially adversely affected.

REINSURANCE

Reinsurance may not be available or adequate to protect us against losses.

We use reinsurance to help manage our exposure to insurance risks. The availability and cost of reinsurance
are subject to prevailing market conditions, both in terms of price and available capacity, which can affect our
business volume and profitability. Although the reinsurer is liable to us to the extent of the ceded reinsurance, we
remain liable as the direct insurer on all risks reinsured. As a result, ceded reinsurance arrangements do not
eliminate our obligation to pay claims. We are subject to credit risk with respect to our ability to recover amounts
due from reinsurers. Reinsurance may not be adequate to protect us against losses and may not be available to us
in the future at commercially reasonable rates. In addition, the magnitude of losses in the reinsurance industry
resulting from catastrophes may adversely affect the financial strength of certain reinsurers, which may result in
our inability to collect or recover reinsurance. Reinsurers also may reserve their right to dispute coverage with
respect to specific claims. With respect to catastrophic or other loss, if we experience difficulty collecting from
reinsurers or obtaining additional reinsurance in the future, we will bear a greater portion of the total financial
responsibility for such loss, which could materially reduce our profitability or harm our financial condition.

NONSTANDARD SEGMENT

The nonstandard auto market may be shrinking due to refined segmentation by key competitors.

Over the last two years, we have experienced significant declines in our nonstandard auto premium, in terms
of dollars and exposure units. While some of this decline was due to actions we undertook to improve the
profitability of this segment, we perceive that key competitors have refined their rating segmentation, including
increased utilization of multi-variant rating models, which we believe has resulted in a shrinkage of the
nonstandard auto market. With the introduction of sophisticated pricing tools by our competitors, and most
recently by us with the introduction of our CustomFit™ product, the criteria for qualifying for the standard auto
segment is much broader, so that the standard auto segment may accommodate some insureds who, to this point,
would have been nonstandard candidates only. Consequently, there is no assurance that the decline in revenues
and net underwriting profits within our nonstandard segment will not continue as a result of the changes taking

19

place in the nonstandard auto market and our own implementation of more inclusive marketing and underwriting
programs in the standard segment.

CYCLICAL NATURE OF THE INDUSTRY

The property and casualty insurance industry is highly cyclical, which may cause fluctuations in our

operating results.

The property and casualty insurance industry, particularly commercial lines businesses, has been historically
characterized by periods of intense price competition due to excess underwriting capacity, as well as periods of
shortages of underwriting capacity that allow for attractive premiums. The periods of intense price competition
may adversely affect our operating results, and the overall cyclicality of the industry may cause fluctuations in
our operating results. In response to periods of intense price competition, our strategy with respect to our
commercial lines business has been to adjust prices to allow for acceptable profit levels and to decline coverage
in situations where pricing or risk would not result in acceptable returns. Accordingly, our commercial lines
business tends to contract during periods of severe competition and price declines and expand when market
pricing allows an acceptable return.

The personal lines businesses are characterized by an auto underwriting cycle of loss cost trends. Driving
patterns, inflation in the cost of auto repairs and medical care and increasing litigation of liability claims are
some of the more important factors that affect loss cost trends. Inflation in the cost of building materials and
labor costs and demand caused by weather-related catastrophic events affect personal lines homeowners loss cost
trends. We and other personal lines insurers are generally unable to increase premiums unless permitted by
changes in insurance laws and regulations, typically after the costs associated with the coverage have increased.
Accordingly, profit margins generally decline in a period of increasing loss costs.

DISTRIBUTION SYSTEM

The independent agency system is our distribution system for our products, which may constrain our

ability to grow at a comparable pace to our competitors that utilize multiple distribution channels.

We market our insurance products through independent, non-exclusive insurance agents, whereas some of
our competitors sell their insurance products through direct marketing campaigns, the internet or insurance
agents who sell products exclusively for one insurance company. The State Auto Group has supported the
independent agency system as our sole distribution channel for the past 85 years. However, we recognize that the
number of independent agencies in the industry has dramatically shrunk over the past several years due to agency
purchases, consolidations, or bankruptcies and the retirement of agents. We also recognize that it will be
progressively more difficult to expand the number of independent agencies representing our company. If we are
unsuccessful in maintaining and increasing the number of agencies in our independent agency distribution
system, our sales and results of operations could be adversely affected.

The agents that market and sell our products also sell products of our competitors. These agents may
recommend our competitors’ products over our products or may stop selling our products altogether. Our strategy
of not pursuing market share at rates that are not expected to produce a combined ratio that meets our goal of
96% or better can have the effect of making top line growth more difficult. When price competition is intense,
this effect is exaggerated by the fact that our independent agent distribution force has products to sell from other
carriers that may be more willing to lower rates to grow top line sales. Consequently, we must remain focused on
attracting and retaining productive agents to market and sell our products. We compete with our competitors for
productive agents primarily on the basis of our financial position, support services, ease of doing business,
compensation and product features. Although we make efforts to ensure that we have strong relationships with
our independent agents and to persuade them to promote and sell our products, we may not be successful in these
efforts. If we are unsuccessful in attracting and retaining these agents, our sales and results of operations could be
adversely affected.

20

REGULATION

Our business is heavily regulated, and changes in regulation may reduce our profitability and limit our

growth.

We are subject to extensive regulation in the states in which we conduct business. This regulation is
generally designed to protect the interests of policyholders, as opposed to shareholders and other investors, and
relates to authorization for lines of business, capital and surplus requirements,
limitations,
underwriting limitations, transactions with affiliates, dividend limitations, changes in control, premium rates and
a variety of other financial and non-financial components of an insurance company’s business.

investment

In recent years, the state insurance regulatory framework has come under increased federal scrutiny, and
some state legislatures have considered or enacted laws that may alter or increase state authority to regulate
insurance companies and insurance holding companies. Further, the NAIC and state insurance regulators are
reexamining existing laws and regulations, specifically focusing on modifications to holding company
regulations, interpretations of existing laws and the development of new laws. In addition, Congress and some
federal agencies from time to time investigate the current condition of insurance regulation in the United States
to determine whether to impose federal regulation or to allow an optional federal charter, similar to banks. We
cannot predict with certainty the effect any proposed or future legislation or NAIC initiatives may have on the
conduct of our business. In addition, the insurance laws or regulations adopted or amended from time to time
may be more restrictive or may result in materially higher costs than current requirements. Although the federal
government does not directly regulate the insurance business, changes in federal legislation and administrative
policies in several areas, including changes in the Gramm-Leach-Bliley Act, financial services regulation and
federal taxation, can significantly harm the insurance industry and us.

CLAIM AND COVERAGE DEVELOPMENTS

Developing claim and coverage issues in our industry are uncertain and may adversely affect our

insurance operations.

As industry practices and legislative, judicial and regulatory conditions change, unexpected and unintended
issues related to claims and coverage may develop. These issues could have an adverse effect on our business by
either extending coverage beyond our underwriting intent or by increasing the number or size of claims. The
premiums we charge for our insurance products are based upon certain risk expectations. When the legislative,
judicial or regulatory authorities expand the burden of risk beyond our expectations, the premiums we previously
charged or collected may no longer be sufficient to cover the risk, and we do not have the ability to retroactively
modify premium amounts. Recent examples of these claims and coverage issues include:

•

•

•

changes in interpretation of the named insured provision with respect to the uninsured/underinsured
motorist coverage in commercial auto policies that broaden the definition of the named insured;

a growing trend of plaintiffs targeting property and casualty insurers, including us, in purported class
action litigation relating to claim-handling and other practices, particularly with respect to the handling
of personal lines auto and homeowners claims; and

increases in the number and size of water damage claims related to expenses for testing and remediation
of mold conditions.

Class action lawsuits relating to property and casualty losses arising out of hurricane Katrina have been filed
in Mississippi against several named insurers and dozens of unnamed insurers. To date, we have not been named
as a defendant or served with process in any of these lawsuits. However, that situation could change in the future.
Based on our understanding of the nature of these lawsuits, the plaintiffs are attempting to expand the scope of
coverage available under their insurance policies to secure claims for compensation for an event that would
otherwise not be covered by their insurance policies. The principal focus of these lawsuits, including one lawsuit

21

being brought by the attorney general of Mississippi, is to have the insurer-defendants’ policies cover flood
losses that are excluded under the typical property insurance policy. Because of the preliminary nature of these
lawsuits, it cannot be determined to what extent, if any, such lawsuits will impact us, or even if we will be named
as a defendant in these lawsuits.

Many of these issues are beyond our control. The effects of these and other unforeseen claims and coverage

issues are extremely hard to predict and could materially harm our business and results of operations.

TERRORISM

Terrorist attacks, and the threat of terrorist attacks, and ensuing events could have an adverse effect on us.

Terrorism, both within the United States and abroad, and military and other actions and heightened security
measures in response to these types of threats, may cause loss of life, property damage, additional disruptions to
commerce and reduced economic activity. Actual terrorist attacks could cause losses from insurance claims
related to the property and casualty insurance operations of the State Auto Group, as well as a decrease in our
shareholders’ equity, net income and/or revenue. The Terrorism Acts require the federal government and the
insurance industry to share in insured losses up to $100 billion per year resulting from certain future terrorist
attacks within the United States. Under the Terrorism Acts, we must offer our commercial policyholders
coverage against certified acts of terrorism. In addition to certified acts of terrorism, we intend, subject to the
approval of the state regulators, to cover only such acts of terrorism that are not certified acts under the Terrorism
Acts and that do not arise out of nuclear, biological or chemical agents.

In addition, some of the assets in our investment portfolio may be adversely affected by declines in the
equity markets and economic activity caused by the continued threat of terrorism, ongoing military and other
actions and heightened security measures. We cannot predict at this time whether and the extent to which
industry sectors in which we maintain investments may suffer losses as a result of potentially decreased
commercial and economic activity, or how any such decrease might impact the ability of companies within the
affected industry sectors to pay interest or principal on their securities, or how the value of any underlying
collateral might be affected.

TECHNOLOGY

Our development of commercial automated underwriting tools may not be successful or the benefits may

not be realized.

We are developing a commercial lines automation system that will build upon the success we believe we
have achieved through our personal lines netXpress system. netXpress allows agents to obtain rates for applicants
on-line in real time, secure consumer reports required for rating or underwriting, all of which combined enable
the agent to offer a firm quote to a customer in real time at the point of sale.

It is our intention to develop similar functionality in commercial lines as we have in personal lines through
netXpress. While this represents a significant commitment of resources over the next 18 to 36 months, we
believe it is vitally important to our ability to maintain our prospects in commercial lines. We cannot assure
shareholders that the development of this technology will be completed within the timeframe projected, or that it
will be successful upon implementation. Additionally, because some of our competitors have already
implemented or may be implementing similar
types of underwriting tools, we may be competitively
disadvantaged. A challenge during this development phase will be the utilization of today’s technology in face of
a constantly changing technological landscape. There can be no assurance that the development of today’s
technology for tomorrow’s use will not result in our being competitively disadvantaged, especially among the
larger national carriers that have greater financial and human resources than we.

22

INVESTMENTS

The performance of our investment portfolios is subject to investment risks.

Like other property and casualty insurance companies, we depend on income from our investment portfolio
for a significant portion of our revenues and earnings and are therefore subject to market risk, the risk that we
will incur losses due to adverse changes in equity, interest, commodity or foreign currency exchange rates and
prices. Our primary market risk exposures are to changes in interest rates and equity prices.

If the fixed-income or equity portfolios, or both, were to be impaired by market, sector or issuer-specific
conditions to a substantial degree, our liquidity, financial position and financial results could be materially
adversely affected. Under these circumstances, our income from these investments could be materially reduced,
and declines in the value of certain securities could further reduce our reported earnings and capital levels. A
decrease in value of our investment portfolio could also put our insurance subsidiaries at risk of failing to satisfy
regulatory minimum capital requirements. If we were not at that time able to supplement our subsidiaries’ capital
from STFC or by issuing debt or equity securities on acceptable terms, our business could be materially
adversely affected. Also, a decline in market rates could also cause the investments in our pension plans to
decrease below the accumulated benefit obligation, resulting in additional pension liability and expense and
increasing required contributions to the pension plan.

In addition, both the fixed-income and the common equity portfolios are subject to risks inherent in the
nation’s and world’s capital markets. The functioning of those markets, the values of the investments held by us
and our ability to liquidate investments on favorable terms or short notice may be adversely affected if those
markets are disrupted or otherwise affected by local, national or international events, such as power outages,
system failures, wars or terrorist attacks or by recessions or depressions, a significant change in inflation
expectations, a significant devaluation of governmental or private sector credit, currencies or financial markets
and other factors or events.

EMPLOYEES

Our ability to attract, develop and retain talented employees, managers and executives, and to maintain

appropriate staffing levels, is critical to our success.

Our success depends on our ability to attract, develop and retain talented employees, including executives
and other key managers in such a specialized industry. Our loss of certain key officers and employees or the
failure to attract and develop talented new executives and managers could have a materially adverse effect on our
business.

In addition, we must forecast the changing business environments (for multiple business units and in many
geographic markets) with reasonable accuracy and adjust hiring programs and/or employment levels accordingly.
Our failure to recognize the need for such adjustments, or the failure or inability to react appropriately on a
timely basis, could lead either to over-staffing (which would adversely affect our cost structure) or under-staffing
(impairing our ability to service its ongoing and new business) in one or more business units or locations. In
either event, our financial results could be materially adversely affected.

BUSINESS CONTINUITY

Our business depends on the uninterrupted operation of our facilities, systems and business functions,

including our information technology and other business systems.

Our business is highly dependent upon our ability to perform, in an efficient and uninterrupted fashion,
necessary business functions, such as Internet support and 24-hour claims contact centers, processing new and
renewal business, and processing and paying claims. A shut-down of or inability to access one or more of our

23

facilities, a power outage, or a failure of one or more of our information technology, telecommunications or other
systems could significantly impair our ability to perform such functions on a timely basis. In addition, because
our information technology and telecommunications systems interface with and depend on third party systems,
we could experience service denials if demand for such service exceeds capacity or a third party system fails or
experiences an interruption. If sustained or repeated, such a business interruption, systems failure or service
denial could result in a deterioration of our ability to write and process new and renewal business, provide
customer service, pay claims in a timely manner or perform other necessary corporate functions. This could
result in a materially adverse effect on our business results and liquidity.

A security breach of our computer systems could also interrupt or damage our operations or harm our
reputation. In addition, we could be subject to liability if confidential customer information is misappropriated
from our computer systems. Despite the implementation of security measures, including hiring an independent
firm to perform intrusion vulnerability testing of our computer systems, these systems may be vulnerable to
physical break-ins, computer viruses, programming errors, attacks by third parties or similar disruptive problems.
Any well-publicized compromise of security could deter people from entering into transactions that involve
transmitting confidential information to our systems, which could have a material adverse effect on our business.

We have established a business continuity plan in an effort to ensure the continuation of core business
operations in the event that normal business operations could not be performed due to a catastrophic event. While
we continue to test and assess our business continuity plan to ensure it meets the needs of our core business
operations and addresses multiple business interruption events,
there is no assurance that core business
operations could be performed upon the occurrence of such an event.

ACQUISITIONS

Acquisitions subject us to a number of financial and operational risks.

Since going public in 1991, we and Mutual have acquired other insurance companies, such as Meridian
Mutual, the MIGI Insurers, Milbank, Farmers and SA Wisconsin, and it is anticipated that we and Mutual may
continue to pursue acquisitions of other insurance companies in the future. Acquisitions involve numerous risks
and uncertainties, such as:

•

•

•

•

•

•

•

obtaining necessary regulatory approvals of the acquisition may prove to be more difficult
anticipated;

than

integrating the acquired business may prove to be more costly than anticipated;

integrating the acquired business without material disruption to existing operations may prove to be
more difficult than anticipated;

anticipated cost savings may not be fully realized (or not realized within the anticipated time frame);

loss results of the company acquired may be worse than expected;

losses may develop differently than what we expected them to; and

retaining key employees of the acquired business may prove to be more difficult than anticipated.

In addition, other companies in the insurance industry have similar acquisition strategies. Competition for
acquisitions may intensify or we may not be able to complete such acquisitions on terms and conditions
acceptable to us. Additionally, the costs of unsuccessful acquisition efforts may adversely affect our financial
performance.

FINANCIAL STRENGTH RATINGS

A downgrade in our financial strength ratings may negatively affect our business.

Insurance companies are subject to financial strength ratings produced by external rating agencies. Higher
ratings generally indicate financial stability and a strong ability to pay claims. Ratings are assigned by rating

24

agencies to insurers based upon factors that they believe are relevant to policyholders. Ratings are important to
maintaining public confidence in our company and in our ability to market our products. A downgrade in our
financial strength ratings could, among other things, negatively affect our ability to sell certain insurance
products, our relationships with agents, new sales and our ability to compete.

Although other agencies cover the property and casualty industry, we believe our ability to write business is
most influenced by our rating from A.M. Best. According to A.M. Best, its ratings are designed to assess an
insurer’s financial strength and ability to meet ongoing obligations to policyholders. The Pooled Companies
currently have a rating from A.M. Best Company of A+ (Superior) (the second highest of A.M. Best’s 15
ratings). We may not be able to maintain our current A.M. Best ratings.

CONTROL BY MUTUAL

Mutual owns a significant interest in us and may exercise its control in a manner detrimental to your

interests.

As of December 31, 2005, Mutual owned approximately 65% of the voting power of our company.
Therefore, Mutual has the power to direct our affairs and is able to determine the outcome of substantially all
matters required to be submitted to shareholders for approval, including the election of all our directors. Mutual
could exercise its control over us in a manner detrimental to the interests of other STFC shareholders.

COMPETITION

Our industry is highly competitive, which could adversely affect our sales and profitability.

The property and casualty insurance business is highly competitive, and we compete with a large number of
other insurers. Many of our competitors have well-established national reputations, and substantially greater
financial, technical and operating resources and market share than us. We may not be able to effectively compete,
which could adversely affect our sales or profitability. We believe that competition in our lines of business is
based primarily on price, service, commission structure, product features, financial strength ratings, reputation
including
and name or brand recognition. Our competitors sell
independent agents, captive agents and directly to the consumer. We compete not only for business and
individual customers, employer and other group customers but also for independent agents to market and sell our
products. Some of our competitors offer a broader array of products, have more competitive pricing or have
higher claims paying ability ratings. In addition, other financial institutions are now able to offer services similar
to our own as a result of the Gramm-Leach-Bliley Act.

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

OVERVIEW

State Auto Financial is a property and casualty insurance holding company primarily engaged in writing
both personal and commercial lines of insurance. The State Auto Group (defined below) writes a broad line of
property and casualty insurance products through approximately 22,100 independent insurance agents associated
with approximately 3,050 agencies in 27 states.

State Auto Financial’s subsidiaries are State Auto P&C, Milbank, Farmers, SA Ohio and SA National, each
of which is a property and casualty insurance company; Stateco, which provides investment management
services to affiliated insurance companies; S.I.S., a developer and seller of insurance-related software; and 518
PML, which owns and leases real and personal property to affiliated companies. State Auto Financial and these
subsidiaries are collectively referred to as the “Company.”

Mutual owns approximately 65% of State Auto Financial’s outstanding common shares. Mutual is one of
only 14 companies in the United States to have been rated A+ (Superior) or higher by A.M. Best Company every
year since 1954. Mutual’s subsidiaries and affiliates are SA Florida and SA Wisconsin, each of which is a
property and casualty insurance company; MIGI, an insurance holding company; Meridian Security, a property
and casualty insurance company; and Meridian Citizens Mutual, a mutual property and casualty insurance
company. Meridian Security and Meridian Citizens Mutual are collectively referred to as the “MIGI Insurers”
and, together with MIGI, the “MIGI Companies.”

The Pooled Companies (defined below) provide a broad line of property and casualty insurance, such as
standard personal and commercial automobile, homeowners, commercial multi-peril, workers’ compensation,
general liability and fire insurance. SA National provides nonstandard personal automobile insurance to the
nonstandard insurance market. The Pooled Companies and SA National are collectively referred to as the “State
Auto Group.”

State Auto P&C, Milbank, Farmers and SA Ohio (the “STFC Pooled Companies”) participate in a quota
share reinsurance pooling arrangement (the “Pooling Arrangement”) with Mutual, SA Wisconsin, SA Florida and
the Meridian Insurers (the “Mutual Pooled Companies” and, together with the STFC Pooled Companies, the
“Pooled Companies”). The Pooling Arrangement covers all the property and casualty insurance written by the
Pooled Companies except voluntary assumed reinsurance written by Mutual, State Auto Middle Market
Insurance (as defined in the 2005 Pooling Agreement) and intercompany catastrophe reinsurance written by State
Auto P&C. Under the Pooling Arrangement, each of the Pooled Companies cedes premiums, losses and expenses
on all of its business to Mutual, and Mutual in turn cedes to each of the Pooled Companies a specified portion of
premiums, losses and expenses based on each of the Pooled Companies’ respective pooling percentages. Mutual
then retains the balance of the pooled business. The participation percentage for the STFC Pooled Companies has
remained at 80% since October 1, 2001. As of January 1, 2005, the Pooling Arrangement was amended to add
the Meridian Insurers as participants. In conjunction with this amendment, the STFC Pooled Companies received
$54.0 million in cash from the Meridian Insurers which related to the additional net insurance liabilities assumed
on January 1, 2005. The following table presents the impact on the Company’s balance sheet relating to the
additional net insurance liabilities assumed on this date:

EXECUTIVE SUMMARY

The results of our operations from year-to-year and quarter-to-quarter are primarily driven by our ability to
generate revenue through premium growth, price and sell our insurance products at levels which will generate
underwriting profits, and establish appropriate loss reserves. In addition, our results are significantly impacted by
the occurrence of catastrophic events, which are generally beyond our control.

• Revenues/Underwriting Profitability: The property and casualty insurance industry is highly cyclical.
Our industry has been historically characterized by periods of intense price competition due to excess
underwriting capacity, as well as periods of shortages of underwriting capacity that allow for attractive
premiums. During periods of excess underwriting capacity, some property and casualty insurers attempt
to generate additional top line growth by setting their prices at levels inappropriate for the risk
underwritten. While in the short term this may result in additional revenues, this action compromises
their underwriting profitability. Our strategy, however, is to adhere to disciplined and consistent
underwriting principles. These principles include insistence on selecting and retaining business based on
the merits of each account and a dedication to cost-based pricing, where each line of business is priced
at a rate anticipated to generate a profit. It is our intention to set pricing levels so that no line of
business, or classification within major lines, subsidizes another line or classification. We are committed
to achieving our goal of a combined ratio of 96% or better through all market cycles, even at the
expense of periodic slowdowns in written and earned premiums. We will not compromise underwriting
profitability for top line growth. We believe that we can implement periodic rate changes in most states
and remain an attractive market to our policyholders and independent agency partners by stressing the
strengths we bring to the marketplace. These strengths include stability, financial soundness, prompt and
fair claims service, and technology which makes it easier for the agent to do business with the State
Auto Group and provide substantial value to our customers.

•

Loss Reserves: We maintain reserves for the eventual payment of losses and loss expenses for both
reported claims and incurred claims that have not yet been reported. Loss reserves are management’s
best estimates at a given point in time of what we expect to pay to claimants, based on facts,

29

circumstances and historical trends then known. During the loss settlement period, additional facts
regarding individual claims may become known, and consequently it often becomes necessary to refine
and adjust the estimates of liability. Loss expense reserves are intended to cover the ultimate costs of
settling all losses, including investigation, litigation and in-house claims processing costs from such
losses. Reserves for reported losses are initially established on either a case-by-case or formula basis
depending on the type and circumstances of the loss. The case-by-case reserve amounts are determined
based on our reserving practices, which take into account the type of risk, the circumstances surrounding
each claim and policy provisions relating to types of loss. The formula reserves are based on historical
paid loss data for similar claims with provisions for trend changes caused by inflation. Loss and loss
expense reserves for incurred claims that have not yet been reported are estimated based on many
variables including historical and statistical
information, inflation, legal developments, storm loss
estimates, and economic conditions. Case and formula basis loss reserves are reviewed on a regular
basis. As new data becomes available, estimates are updated resulting in adjustments to loss reserves.
Generally, reported losses initially reserved on a formula basis which have not settled after six months
are case reserved at that time. Although management uses many resources to calculate reserves, there is
no precise method for determining the ultimate liability. We do not discount loss reserves for financial
statement purposes. Our objective is to set reserves that are adequate such that the amounts that we
originally record as reserves reasonably approximate the ultimate liability for insured losses and loss
expenses. We then periodically review and adjust loss reserves on a timely basis. This ongoing periodic
review assures a consistent
that any required
adjustment may have on our current operating results.

level of adequacy and also minimizes the impact

• Catastrophic Events: We are exposed to claims arising out of catastrophic events. Catastrophe losses
can and do cause substantial volatility in our financial results for any fiscal quarter or year. Catastrophes
can be caused by various natural events, including hurricanes, hailstorms, tornadoes, windstorms,
earthquakes, severe winter weather and fires, none of which are within our control. The frequency and
severity of catastrophes are inherently unpredictable. The extent of losses from a catastrophe is a
function of both the total amount of insured exposure in the area affected by the event and the severity
of the event. Most catastrophes are restricted to small geographic areas. However, hurricanes and
earthquakes may produce significant damage in larger areas, especially those that are heavily populated.
Although catastrophes can cause losses in a variety of our property and casualty lines, most of our
catastrophe claims in the past have related to homeowners, other personal lines, allied lines and
commercial multiple peril coverages. We deploy specific strategies designed to mitigate our exposure to
catastrophe losses. We continually seek to diversify our business on a geographic basis. The number of
states we operate in has increased from 17 states in 1991 to 27 states in early 2006. The concentration of
gross written premiums for our property and casualty operations in our largest state, Ohio, has decreased
from 28% for the year ended December 31, 1991, to 17.8% for the year ended December 31, 2005. We
avoid writing insurance in states that we believe present difficult legislative, judicial and/or regulatory
environments for the insurance industry. Our underwriting guidelines are designed to limit exposures for
high risk insurance matters such as asbestos, workers’ compensation and environmental claims. Our
catastrophe management strategies are designed to mitigate our exposure to earthquakes and hurricanes.

In addition to our adherence to cost-based pricing and risk mitigation strategies, discussed above,
management of the Company focuses on several other key areas to improve the results of our operations and
financial results. The following are critical areas of management’s focus:

• Claims Service: We believe an important element of our success is our focus on claims service. The role
of the claims division is to deliver the promise that we and the independent agent made to the insured —
that we will strive to provide prompt and fair claims service. We have the capability of receiving claims
24 hours a day, seven days a week. Claims may be reported to our Claims Contact Center, to the
policyholder’s independent agent or via the Internet. We make a pledge to our policyholders to try and
make contact with them within two hours once the claim has been assigned to a claims handler (except
in catastrophe loss situations).

Independent Insurance Agent Network: We offer our products through approximately 22,100
independent insurance agents associated with more than 3,050 agencies in 27 states. We believe the
success of our independent insurance agent network, which is our only distribution channel, grows out
of our commitment to promote and foster close working relationships with our agents. We seek
relationships with agencies where we will be one of their top three insurers, measured on the basis of
direct premiums written, for the type of business we desire. Our agents’ compensation package includes
competitive commission rates and other sales inducements designed to maintain and enhance
relationships with existing independent agents as well as to attract new independent agents. We provide
our agents with a co-operative advertising program, sales training programs, an agent’s stock purchase
program, profit-sharing and travel incentives and agency recognition. We continually monitor our
agencies for compatibility with us, taking into account factors such as loss ratio, premium volume,
business profiles and relationship history. This allows us to be proactive in helping the agents to
enhance profitability and, thus, maintain the advantages of the State Auto affiliation. Our senior
management regularly makes itself available to the agency force to reinforce this partnership
commitment. We believe each of these elements creates a relationship that has resulted in our
independent insurance agents placing quality insurance business with us.

Investment Strategy: We have a conservative investment strategy that emphasizes the quality of our
fixed income portfolio, which comprised 86% of our total portfolio at December 31, 2005, and includes
only investment grade securities. We have a disciplined approach to the equity portion of our portfolio,
which comprised 13.6% of our
that emphasizes large
capitalization, dividend-paying companies. We select equity investments based on a stock’s potential for
appreciation as well as ability to continue paying dividends.

total portfolio at December 31, 2005,

Technology: Recent statistics indicate that approximately 87% of the Company’s personal automobile
and homeowners new business applications and 73% of change requests in these lines of business are
delivered and processed electronically. This increased utilization, specifically the new business
percentage representing a 20 point increase since the 2004 fiscal year, demonstrates our success and
focus with respect to competing on an “ease of doing business” factor. Our internet-based point of sale
agency portal for personal lines business, netXpress, and an automated intelligent underwriting system,
Apollo, are examples of standards-based, user-friendly technology, making it easier for agents to submit
personal lines accounts to us. The Apollo system allows us to make consistent underwriting decisions
across the standard and non-standard lines of business. In 2005, we continued to rollout this system to
additional states, resulting in 171,000 total underwriting decisions rendered. This reflected a 101%
transactions handled by our automated
increase from 2004 for new business and endorsement
underwriting systems. Management’s focus will continue on “ease of doing business” in other ways as
well, such as enhancements to our electronic portal for agents, called Agentsite, and creating ways for
our internet rating and underwriting systems to “talk” with more agency management systems. In 2005,
“Agentsite Dashboard” was added to provide agents with quicker access to customer information and
recent transactions. This new functionality helped agents transition following our decision to eliminate
the printing and mailing of paper policy declarations to agents for personal lines. We have recently
begun work to develop a commercial lines automation system that is intended to build upon the success
we have achieved through our netXpress system for personal lines. netXpress allows agents to obtain
rates for applicants on-line in real time and secure consumer reports required for rating or underwriting,
all of which combined enables the agent to offer a firm quote to a customer in real time at the point of
sale. In order to achieve our goal of commercial lines functionality, we will need to make a significant
commitment of resources over the next 18 to 36 months. However, we believe developing such an
Internet-based system is vitally important to our ability to compete for new commercial lines accounts.

CRITICAL ACCOUNTING POLICIES

The Company’s significant accounting policies are more fully described in Note 1 of the Notes to the
Company’s Consolidated Financial Statements included in Item 8 of this Form 10-K. In preparing the

31

consolidated financial statements, management is required to make estimates and assumptions that affect the
reported amounts of assets and liabilities as of the date of the balance sheet, revenues and expenses for the period
then ended and the financial entries in the accompanying notes to the financial statements. Such estimates and
assumptions could change in the future, as more information becomes known which could impact the amounts
reported and disclosed therein.

Losses and loss expenses payable are management’s best estimates at a given point in time of what the
Company expects to pay claimants, based on known facts, circumstances and historical trends. Reserves for
reported losses are established on either a case-by-case or formula basis depending on the type and circumstances
of the loss. The case-by-case reserve amounts are determined by claims adjusters based on the Company’s
reserving practices, which take into account the type of risk, the circumstances surrounding each claim and
policy provisions relating to types of loss. The formula reserves are based on historical data for similar claims
with provision for trend changes caused by inflation. Loss and loss expense reserves for incurred claims that have
not yet been reported are estimated based on many variables including historical and statistical information,
inflation, legal developments, storm loss estimates, and economic conditions. Case and formula basis loss
reserves are reviewed on a regular basis, and as new data becomes available, estimates are updated resulting in
adjustments to loss reserves. Generally, reported losses initially reserved on a formula basis and not settled after
six months are case reserved at that time. Although management uses many internal and external resources, as
well as multiple established methodologies to calculate reserves, there is no method for determining the exact
ultimate liability.

Acquisition costs, consisting of commissions, premium taxes and certain underwriting expenses relating to
the production of property and casualty business, are deferred and amortized ratably over the contract period. The
method followed for computing the acquisition costs limits the amount of such deferred costs to their estimated
realizable value. In determining estimated realizable value, the computation gives effect to the premium to be
earned, related investment income, losses and loss expenses expected to be incurred, and certain other costs
expected to be incurred as premium is earned. These amounts are based on estimates, and accordingly, the actual
realizable value may vary from the estimated realizable value.

Pension and postretirement benefit obligations are long term in nature and require management judgment in
estimating the factors used to determine these amounts. Management, along with its defined benefit consulting
actuary, reviews these factors, including the discount rate and expected long term rate of return on plan assets.
Because these obligations are based on management estimates which could change,
the ultimate benefit
obligation could be different from the amount estimated.

Fixed maturity and equity security investments are classified as available-for-sale and carried at fair value.
The unrealized holding gains or losses, net of applicable deferred taxes, are shown as a separate component of
stockholders’ equity as “accumulated other comprehensive income,” and as such are not included in the
determination of net income. Investment income is recognized when earned, and capital gains and losses are
recognized when investments are sold.

The Company regularly monitors its investment portfolio for declines in value that are other-than-
temporary, an assessment that requires significant management judgment. Among the factors management
considers are the nature of the investment, severity and length of decline in fair value, events impacting the
issuer, overall market conditions and its intent and ability to hold securities until the value recovers. When a
security in the Company’s investment portfolio has been determined to have a decline in fair value that is other-
than-temporary, the Company adjusts the cost basis of the security to fair value. This results in a charge to
earnings as a realized loss, which is not changed for subsequent recoveries in fair value.

Other items that could have a significant

impact on the financial statements include the risks and
uncertainties listed in Item 1A of this Form 10-K under “Risk Factors.” Actual results could differ materially
using different estimates and assumptions, or if conditions are significantly different in the future.

The reader is referred to the complete disclosure on reportable segments in Note 15, Reportable Segments,

of the Notes to the Company’s Consolidated Financial Statements included in Item 8 of this Form 10-K.

The investment management services segment reflects management of the investment portfolios of affiliate
companies. Its significant source of segment profit is the fee generated from providing this service. This
segment’s revenue is based on the average fair value of the portfolios managed. Beginning January 1, 2006, the
investment management services segment will be included in the all other category as the results of this segment
no longer meets the quantitative thresholds for separate presentation as a reportable segment even with
consideration of aggregation of other segments with similar economic characteristics, among other factors.

A critical measure of a successful property and casualty insurance company is whether or not it consistently
produces an underwriting profit during all market cycles. When underwriting is not profitable, insurance losses
and related acquisition and operating expenses exceed premiums. Sustained underwriting losses can place an
insurer at greater risk of insolvency than an insurer which is profitable from an underwriting standpoint. The
Company has consistently focused on producing an underwriting profit and, therefore, views its underwriting
results during all market cycles as the most important measure of its overall operating performance.

The Company monitors the performance of

its insurance segments by concentrating on segment
underwriting profit and combined ratio. Underwriting profit under Statutory Accounting Principles (“SAP”) is
determined by subtracting from earned premiums, losses and loss expenses and net underwriting expenses
incurred. SAP requires all underwriting expenses to be expensed immediately and not deferred over the same
period that the premium is earned. Generally Accepted Accounting Principles (“GAAP”), however, require the
recognition of acquisition costs as the premiums are earned. In converting SAP underwriting results to GAAP
underwriting results, acquisition costs are deferred and amortized over the periods the related written premiums
are earned. See the discussion of deferred policy acquisition costs under Critical Accounting Policies included
herein. The “GAAP Combined Ratio” is defined as the sum of the “GAAP loss and LAE ratio” (loss and loss
expenses, as a percentage of earned premiums) plus “GAAP expense ratio” (acquisition and operating expenses,
as a percentage of earned premiums). When the combined ratio is less than 100%, the insurer is operating at an
underwriting profit. When the combined ratio is greater than 100%, the insurer is operating at an underwriting
loss.

The following tables provides a summary of the insurance segments’ GAAP underwriting profit (in dollars),
GAAP Combined Ratio along with related segment net investment income, for the years 2005, 2004 and 2003,
respectively. The tabular information provided is net of adjustments for transactions with other segments.

Includes $24.0 million of unearned premium transferred to the Company in connection with the addition of the Meridian Insurers to the
Pooling Arrangement.

Written premiums are recognized as earned based upon the contract terms of the underlying policies. The
unearned premium represents the deferred revenues of the unexpired terms of coverage which are earned ratably
over the policy period.

During each of the three years ended December 31, 2005, the Company’s insurance segments attained then
record level net underwriting profit while also incurring then record level catastrophe losses in terms of dollars.
Absent these losses, the Company’s core results remained strong in 2005 in comparison to the same 2004 and
2003 periods. This core improvement over the three-year period is the direct result of the Company maintaining
adequate cost-based rates and monitoring risk selection. While written premium growth in 2005 was not at a rate
comparable to that achieved in 2004 and 2003, the Company maintained the focus that it has demonstrated since
its initial public offering in 1991—achieving premium growth without compromising underwriting profit.

2005 Compared to 2004

Income before federal income taxes for the Company increased $20.4 million (13.5%) to $172.0 million in
2005 from 2004. The most significant factors contributing to this increase were an improvement
in the
Company’s loss experience from 2004 along with growth in earned premium and net investment income. The
Company’s GAAP loss and LAE ratio reflected an improvement to 58.4 points from 61.5 points in 2004, despite
2005 being the largest catastrophe loss year in the Company’s history in terms of dollars. As discussed in more
detail below, the Company’s challenge has been to grow premiums without compromising profitability as
industry-wide price competition increased.

Consolidated earned premiums increased $43.5 million (4.3%) to $1,050.3 million in 2005 from 2004. This
increase was principally the result of the addition of the Meridian Insurers to the Pooling Arrangement,
previously discussed. During 2005, earned premiums within the standard segment increased $61.9 million
(6.6%) to $997.2 million from the same 2004 period, with $46.2 million of the increase (4.9 points) coming from
the addition of the Meridian Insurers to the Pooling Arrangement and $15.7 million (1.7 points) from internal
growth. Internal growth was primarily driven by more moderate base rate increases in most lines of business and
actual decreases in other lines. In addition, price competition in personal lines continues to be intense and is
having an adverse impact on new and renewal business. These developments are at least in part the result of an
increasingly competitive market place being driven by certain insurance companies who we believe may have
different underwriting performance expectations from those of the Company. The Company remains committed
to achieving its goal of a combined ratio of 96% or better, even at the expense of periodic slowdowns in earned
premiums.

Earned premiums within the nonstandard segment decreased $18.4 million (25.7%) to $53.1 million in 2005
from the same 2004 period. The nonstandard automobile market is highly price sensitive, which had and is
having an adverse impact on new and renewal business. The Company constantly pursues rate adequacy while
also working to address unprofitable agencies. For example, over the last year, the Company has been working
with a number of its larger and fast growing agencies in the state of Minnesota where experience has not resulted
in an underwriting profit. As a result, the Company has recently taken corrective action and has either terminated
or suspended several of these Minnesota agencies which will result in a loss of both written premium and policy
count in 2006 in this state. After having achieved an acceptable level of rate adequacy, the Company believes it is
positioned to make targeted pricing and underwriting changes designed to respond to market leaders in the
nonstandard auto market. Some of these changes include more competitive rate levels, including introducing
transfer credits on new business, enhancements to the Company’s classification plans and credit structures, and
expansion of the underwriting market to offer higher liability limits on a selective basis.

Also impacting this segment’s growth is the fact that many nonstandard auto insurers have chosen to reduce
rates, some substantially, in an effort to compete for market share. In addition, with the increased utilization and
refinement of multi-variant rate models by many competitors, the definition of a nonstandard risk is becoming
more ambiguous. As a result, what may have once been perceived as a nonstandard risk may now qualify within
the standard market. The Company is responding by continuing to research and develop pricing enhancements to
fit with the nonstandard auto markets it deems have a higher potential for underwriting profit.

36

The Company’s biggest challenge in 2005 was top line growth in both the standard and nonstandard
segments. As a consequence, the Company implemented a number of initiatives to stimulate sales in personal
lines new business and is working with its independent agency partners to strengthen personal lines sales
techniques and skills. Known by the acronym STAR, this Sales Training for Agency Representatives has now
been delivered to over 1,300 agency representatives, exceeding the Company’s goal of at least 1,000 program
participants during 2005. Additionally, the Company continually reviews its insurance programs in order to
provide insurance to a broader segment in the markets in which it operates. For example, the Company has
expanded eligibility requirements for youthful operators within its standard segment and, as noted, is selectively
offering higher limits within the nonstandard segment. Most recently the Company began to roll out a new
standard private passenger auto multi-variant rating program called CustomFit™—a program that is more
responsive to the risk characteristics of each driver, more accurately matching price to risk, and is intended to
facilitate the Company’s agency partners’ ability to sell this program to a broader segment of its customer base.
The objective is to preserve the Company’s Prime of Life product, which targets the 45 year and older market,
while also becoming more attractive to a broader range of personal lines accounts.

In 2005, the Company appointed 58 new agency partners. Each year the Company terminates its relationship
with some agencies. On occasion the Company has had to either terminate or suspend several fast growing but
unprofitable agencies, as has been the case within the Company’s nonstandard segment, but for the most part, an
overwhelming number of the terminated agencies are usually those that have very little premium with the
Company. The average premium for the agencies terminated in 2005 was $16,000.

The Company continues to emphasize that it will not compromise underwriting profitability for top line
growth. The Company believes that it can implement periodic rate changes in most states and remain an
attractive market to its policyholders and independent agency partners by stressing the strengths it brings to the
marketplace. These strengths include stability, financial soundness, prompt and fair claims service, and
technology which makes it easier for the agent to do business with State Auto and provide substantial value to
their customers. The Company’s Internet-based point of sale agency portal for personal lines business, netXpress,
and an automated intelligent underwriting system, Apollo, are examples of standards-based, user-friendly
technology, making it easier for agents to submit personal lines accounts to the Company.

Recent statistics indicate that approximately 87% of the Company’s personal auto and homeowners new
business applications and 73% of change requests in these lines are delivered and processed electronically. This
increased utilization, specifically the new business percentage representing a 20 point improvement since year
end 2004, demonstrates that the Company’s efforts to compete on “ease of doing business” are achieving
success. The Apollo system allows the Company to make consistent underwriting decisions across the standard
and nonstandard lines of business. In 2005, the rollout of this system to additional states continued, rendering
171,000 total underwriting decisions. This was an increase of 101% over 2004 for new business and endorsement
transactions.

The Company is addressing ease of doing business in other ways as well, including enhancements to its
electronic portal for agents, called Agentsite, and creating ways for the Company’s internet rating and
underwriting systems to “talk” with more agency management systems. In 2005, “Agentsite Dashboard” was
added to provide agents with quicker access to customer information and recent
transactions. This new
functionality helped the agents transition following the Company’s decision to eliminate the printing and mailing
of paper policy declarations to agents for personal lines.

Recently, the State Auto Group began developing a commercial lines automation system that will build
upon the success the Company has achieved through its netXpress system for personal lines. netXpress allows
agents to obtain rates for applicants on-line in real time and secure consumer reports required for rating or
underwriting, all of which combined enables the agent to offer a firm quote to a customer in real time at the point
of sale. It is the intention of the State Auto Group to develop similar functionality in commercial lines. This
represents a significant commitment of resources over the next 18 to 36 months. However, the Company believes
developing this functionality is vitally important to the Company’s ability to compete for new commercial lines
accounts.

Net investment income increased $6.9 million (9.6%) to $78.7 million in 2005 from the same 2004 period.
Strong underwriting results, which contributed positively to the Company’s cash flows during 2005, along with
the $54.0 million in cash received on January 1, 2005 from the Pooling Arrangement amendment, increased the
amount of investable assets from 2004. Total cost of invested assets at the end of 2005 and 2004 was $1,856.5
million and $1,682.7 million, respectively. See “Liquidity and Capital Resources” section included herein for a
discussion on cash flows from operations and financing activities.

The annualized investment yields based on average invested assets at cost decreased to 4.3% in 2005 from

4.5% in 2004. The following has contributed to the current year decline:

•

•

The continued allocation of new monies and reinvestments to tax-exempt municipal bonds in an effort
to maximize after tax profits. The Company’s target allocation is 70% of the total portfolio. Based on
amortized cost, in 2005, municipal bonds accounted for $1,097.3 million (68.7%) of the fixed maturity
portfolio versus $865.4 million (59.6%) in 2004.

In 2005, the Investment Committee of the Company’s Board of Directors approved management’s
recommendation to increase its target allocation for equity securities, which typically have an
investment yield less than fixed maturities, in an effort to mitigate inflation risk and increase the growth
potential of the portfolio. The Company targets those equity securities that demonstrate a history of
dividend payment and potential for capital appreciation. During 2005, the Company added $61.4
million, an increase of 37.6% from 2004, of new investments to the equity securities portfolio.

The combination of these portfolio actions resulted in after tax net investment income of approximately

$65.2 million in 2005 versus $57.9 million in 2004 for an effective tax rate of 17.3% and 19.4%, respectively.

With the shift in the Company’s investment portfolio towards lower yielding securities before tax, the
decrease in assets associated with the repayment of the $45.5 million line of credit with Mutual in December
2005 and increased dividend rate expected to be paid per common share in 2006 (discussed below), net
investment income in 2006 is not expected to increase at a rate comparable to that experienced in 2005.

2004. Most of the net realized gains in 2005 were in the fixed income segment of the portfolio. In many cases,
taxable bonds were sold at a profit with the proceeds being reinvested in the tax-exempt segment. These
transactions helped to further the goal of increasing the tax-exempt portion of the portfolio. In other cases, bonds
with lower coupons were sold with the proceeds reinvested in higher coupon bonds in order to increase interest
income for the Company. Equity securities were sold due to changing fundamentals, mergers or acquisitions, and

38

changes in future prospects for the individual companies. The proceeds from these equity sales were almost
entirely reinvested into equity securities of other companies.

The Company recognized a total of $1.6 million in other-than-temporary impairments in 2005 versus $0.2
million in 2004. Included in the 2005 realized losses of the fixed maturities above, was $0.6 million related to
other-than-temporary impairments on two fixed maturity securities, specifically within the other debt securities
investment category, which continue to be held by the Company at December 31, 2005. Included in realized
losses related to equity securities is $1.0 million related to an other-than-temporary impairment on one equity
position within the financial services sector of the portfolio. This particular security is no longer held by the
Company at December 31, 2005. The individual circumstances involving the other-than-temporary impairments
recognized in 2005 were limited to those securities.

section, included herein.

Expenses

Losses and loss expenses, as a percentage of earned premiums (the “GAAP loss and LAE ratio” or “loss
ratio”), were 58.4% and 61.5% for the years 2005 and 2004, respectively. Losses and loss expenses for a calendar
year represent the combined estimated ultimate liability for claims occurring in the current calendar year along
with development of claims occurring in prior years. The following table presents the provision for losses and
loss expenses for those claims occurring in the current calendar year and prior years, along with the respective
impact on the current calendar year GAAP loss and LAE ratio for the years 2005 and 2004, respectively:

Normal fluctuations and uncertainty associated with loss reserve development and claim settlement
contributed to favorable development in the respective calendar years. Also contributing to the 2005 favorable
development was $5.8 million favorable development of 2004 and prior catastrophe losses, discussed below,
approximately $14.4 million of favorable development on ceded claim reserves, along with lower cost
projections for ULAE reserves (defined below). See additional discussion at the “Other - Loss Reserves” section
included herein.

Catastrophe losses in 2005 totaled $72.7 million (6.9 loss ratio points) compared to $70.7 million (7.0 loss
ratio points) for the same 2004 period. Catastrophe losses occurring during 2005 were offset by net favorable
development of $5.8 million (0.6 loss ratio points) from weather related catastrophes that occurred primarily
during the third and fourth quarters of 2004. Catastrophe losses discussed herein include those which have been
designated as such by ISO’s Property Claim Services (“PCS”) unit, a nationally recognized industry service. PCS
defines catastrophes as events resulting in $25.0 million or more in insured losses industry wide and affecting
significant numbers of insureds and insurers. While not meeting PCS’ definition of an industry catastrophic
event, any event or series of related events resulting in ultimate losses to the State Auto Group in excess of $2.0
million have been included by the Company under its catastrophe losses.

39

During the third and fourth quarters of 2005, the Company experienced weather related catastrophe losses
that include losses from hurricanes Cindy, Dennis, Katrina, Ophelia, Rita and Wilma along with two north-
central states hail storms. The most significant losses were as follows: hurricane Katrina, totaling $32.0 million
or 3.1 loss ratio points, which includes reinsurance assessments, primarily from the Mississippi Windstorm
Underwriting Association, of approximately $7.9 million or 0.8 loss ratio points; two north-central states hail
storms totaling $14.8 million or 1.4 loss ratio points; and hurricane Wilma, totaling $9.7 million of losses or 0.9
loss ratio points. Collectively, these three weather related catastrophes accounted for $56.5 million in losses or
5.4 loss ratio points in 2005. The comparable 2004 period was impacted by catastrophe losses related to
hurricanes Charley, Frances, Jean and Ivan. Collectively, these hurricanes contributed $39.6 million in losses or
3.9 loss ratio points in 2004.

In today’s market, the cost of the goods and services purchased by insurance companies in settling property
claims has been steadily increasing at a rate higher than normal inflation. This increase has been driven largely
by the surge in demand for building materials both following the 2005 and 2004 hurricane losses as well as
foreign consumption of the same materials. As loss cost trends change, the Company intends to continue to
adjust its pricing projections in order to ensure premiums keep pace with market conditions.

The following table summarizes the consolidated GAAP loss and LAE ratio by segment and by line of

business for the years ended December 31, 2005 and 2004, respectively:

The Company monitors all lines of business, paying particular attention to personal auto (standard and
nonstandard) due to the significance this line has on the profitability of the Company and the fact that it accounts
for approximately 42% of total earned premium of the Company. The GAAP loss and LAE ratio of standard
personal auto increased to 59.3% in 2005 from 58.2% in 2004. An increase in both the frequency and severity of
losses within the bodily injury coverage of this line of business largely contributed to this increase. It is important
to note that the Company’s auto rate levels are reviewed each year in detail for each state to adjust for changing
claim patterns and claim costs. In most states, this has resulted in increasing liability rates and decreasing
physical damage rates. While these loss costs trends increased for bodily injury coverage over recent quarters, the
Company does not consider this a major deviation from the expected long term trend for the overall line.
Nonetheless, the Company will continue to examine the auto trends by coverage and address any problems with
appropriate pricing and underwriting action.

Nonstandard personal auto’s GAAP loss and LAE ratio improved 6.1 loss ratio points from the same 2004
period. The Company continually monitors this segment’s risk selection and rate adequacy as this line of

40

business tends to be more volatile in terms of loss frequency than the standard segment. The Company’s focus on
rate adequacy and monitoring its independent agency partners’ performance, in terms of both growth and profit,
has significantly improved this segment’s GAAP loss and LAE ratio from previous years, specifically 2003 and
2002.

Largely impacting the improvement in many of the Company’s lines of business is that 2005 is the first year
that the Company is earning the rate changes implemented in 2004 and 2005. The Company is benefiting from
cumulative rate changes taken over the past four years.

Within the fire and allied lines, the 5.9 point increase in GAAP loss and LAE ratio from the same period in
2004 is due to the Company’s reinsurance assessment of $7.9 million related to hurricane Katrina, previously
discussed, which increased this line’s loss and LAE ratio by 9.4 points. The significant improvement in other and
products liability resulted from a decline in the number of large losses (in terms of both frequency and severity),
including umbrella losses, as compared to 2004. While still a profitable line of business, nonetheless, the increase
within the miscellaneous personal and commercial lines’ GAAP loss and LAE ratio in 2005 from 2004 is
attributable to two large surety bond losses that accounted for 4.3 points of the 2005 loss ratio for those lines.

Acquisition and operating expenses, as a percentage of earned premiums (the “GAAP expense ratio” or
“expense ratio points”), were 31.7% and 30.2% in 2005 and 2004, respectively. The 1.5 point increase is largely
due to lower than anticipated written premiums in combination with certain fixed expenses increasing.

Interest expense in 2005 was $8.8 million compared to $7.3 million in 2004. The increase in interest
expense was due to higher interest rates on variable debt in 2005 and the benefit of interest rate swaps in 2004.
See further discussion of the Company’s debt activity in 2005 and 2004 in the section “Liquidity and Capital
Resources—Borrowing Arrangements” included herein.

The consolidated effective tax rate is largely affected by the amount of underwriting profit or loss and net
realized investment gains or losses that are taxed at approximately 35% relative to the amount of net investment
income at its effective tax rate. The 2005 consolidated effective tax rate declined to 26.8% from 27.4% in 2004.
This was principally due to a decline in the 2005 effective tax rate on net investment income to approximately
17.3% versus 19.4% in 2004. Contributing to the decline was the decision by the Company to continue to
increase in 2005 its holdings of tax-exempt municipal bonds as previously discussed.

2004 Compared to 2003

Income before federal income taxes for the Company increased $68.3 million (82.0%) to $151.6 million in
2004 from 2003. The most significant factors contributing to this increase were an improvement
in the
Company’s loss experience from 2003 along with growth in earned premium. The Company’s GAAP loss and
LAE ratio reflected a 6.3 point improvement in 2004 from 2003, despite at that time, 2004 being the largest
catastrophe (in dollars) loss year in the Company’s history.

The following provides a summary of a stop loss reinsurance arrangement (the “Stop Loss”), which expired

on December 31, 2003, that will assist in the discussion of the Company’s related 2003 financial results:

For the period October 1, 2001 through December 31, 2003, Mutual entered into a stop loss reinsurance
arrangement (the “Stop Loss”) with the STFC Pooled Companies. Under the Stop Loss, Mutual agreed to
participate in the Pooling Arrangement’s quarterly underwriting losses and gains in the manner described. If
the Pooling Arrangement’s quarterly statutory loss and loss adjustment expense ratio (the “Pool loss and
LAE ratio”) was between 70.75% and 80.00% (after the application of all available reinsurance), Mutual
reinsured the STFC Pooled Companies 27% of the Pooling Arrangement’s losses in excess of a Pool loss
and LAE ratio of 70.75% up to 80.00%. The STFC Pooled Companies were responsible for their share of
the Pooling Arrangement’s losses over the 80.00% threshold. Also, Mutual had the right to participate in the

41

profits of the Pooling Arrangement. Mutual assumed 27% of the Pooling Arrangement’s underwriting
profits attributable to Pool loss and LAE ratios less than 69.25%, but more than 59.99%. The Stop Loss
arrangement expired at December 31, 2003, and was not renewed.

Consolidated earned premiums increased $46.2 million (4.8%) to $1,006.8 million in 2004 from 2003. The
Company’s standard segment contributed a 4.6% increase to consolidated earned premiums in 2004 from 2003,
while the nonstandard segment experienced a 1.1% decrease in the same period. The 2003 consolidated earned
premiums were affected by the Stop Loss. The STFC Pooled Companies ceded $12.8 million in earned premiums
to Mutual in 2003, which reduced the Company’s earned premiums in 2003 by 1.3%. The Stop Loss reinsurance
agreement expired December 31, 2003 and was not renewed.

As reflected in the table above, earned premiums increased from year to year across almost all lines of
business, with the exception of nonstandard auto, commercial multi-peril and workers’ compensation. Overall the
composition of the Company’s book of business did not change significantly from year to year, with the standard
auto – personal line continuing to be the Company’s most significant line of business.

Earned premiums within the standard segment increased $57.0 million (6.5%) in 2004 from 2003. During
2003 and 2002, the Company took necessary and in some cases significant base rate increases, particularly within
the Meridian book, in almost all lines of business. The impact of these base rate changes affects earned premium
growth in the years following the implementation of these changes. After a number of years of having attained a
healthy degree of rate adequacy, during 2004 the Company implemented more moderate base rate changes,
which was expected to slow earned premium growth. In an effort to address personal lines growth, the Company
introduced programs in 2004 focusing on increasing personal lines applications from its agency partners.
the Company introduced a specialized training program to its agency partners’ service
Additionally,
representatives that focuses specifically on sales techniques.

Earned premiums within the nonstandard segment decreased $10.8 million (13.1%) in 2004 from 2003. The
nonstandard automobile industry is highly price sensitive, which can have an adverse impact on renewal business
as well as new premium growth. In an effort to provide insurance to a broader segment of the nonstandard

42

market, the Company has modified the nonstandard program offering higher limits than have historically been
the case. The Company continues to take cost-based targeted rate increases; however, some nonstandard insurers
took rate decreases in 2004. This intense price competition, along with the Company’s termination or suspension
during 2003 and 2002 of certain fast growing, but unprofitable agencies, has resulted in a decrease in new and
renewal business, which in turn has negatively impacted the Company’s earned premiums.

Net investment income increased $7.2 million (11.1%) to $71.8 million in 2004 from 2003. This growth was
the result of an increase in invested assets generated by cash flow provided by operations and financing activities,
partly offset by a decline in the investment yield. Between April 1, 2003 and December 31, 2003, the Company
issued debt, net of repayments, of $85.5 million. Total cost of invested assets at December 31, 2004 and 2003
was $1,682.8 million and $1,530.1 million, respectively. Invested assets are comprised of total investments and
cash equivalents. Reflecting a decline in the interest rate environment, the annualized investment yields based on
average invested assets at cost decreased to 4.5% in 2004 from 4.6% in 2003. The Company manages its
investment portfolio to maximize after tax profits. With the Company’s improving loss experience throughout
2003, management began allocating a higher proportion of new monies and reinvestments to municipal bonds in
the fourth quarter of 2003 which continued throughout 2004. This reallocation is expected to result in lower
pre-tax investment yields but higher after tax investment income than if the Company continued with the
portfolio allocation of 2003.

Expenses

The GAAP loss and LAE ratios were 61.5% and 67.8% for the years 2004 and 2003, respectively. Losses
and loss expenses for a calendar year represents the combined estimated ultimate liability for claims occurring in
the current calendar year along with development of claims occurring in prior years. The following table presents
the provision for losses and loss expenses for those claims occurring in the current calendar year and prior years,
along with the respective impact on the current calendar year GAAP loss and LAE ratio for the years 2004 and
2003, respectively:

The development in the respective calendar year for claims occurring in prior years is well within normal

expectations for reserve development and claim settlement uncertainty.

For the years 2004 and 2003, catastrophe claims contributed 7.0 and 6.8 points, respectively, to the
consolidated GAAP loss and LAE ratio. During 2004, hurricanes Charley, Frances, Jeanne and Ivan contributed a
total of $39.6 million in catastrophe losses, or 3.9 GAAP loss and LAE ratio points. In 2003, high winds,
tornadoes, hail, lightning and resulting fires from one numbered catastrophe loss caused damage in 17 of the
Company’s 26 operating states (“CAT 88”). Claims resulting from CAT 88 totaled $39.6 million or 4.1 GAAP
loss and LAE points for the year 2003. In terms of dollars, CAT 88 remains the largest single catastrophe loss
event in State Auto history. As discussed below, each of the Company’s insurance operating segments was
impacted by these catastrophe losses.

For the year 2003, the STFC Pooled Companies ceded a total of $12.8 million in earned premium and $5.6
million in losses and loss adjustment expenses to Mutual under the Stop Loss. The net impact of this cession
increased the 2003 GAAP loss and LAE ratio by 0.3 points.

As noted in the above table, all lines of business contributed to the 6.3 point GAAP loss and LAE
improvement in 2004 from 2003, except for auto—commercial and other and products liability, which combined
represent 17.5% of total earned premiums in 2004. The Company monitors all lines of business paying particular
attention to auto—personal, homeowners and workers’ compensation due to the significance these lines have on
the profitability of the Company. The auto—personal line continues to be the most significant line of business
and therefore has the greatest influence on net income. The homeowners line of business is the Company’s
second largest (see earned premium table above) and has been most significantly impacted by weather-related
losses in the last two years by the apparent increased severity of storms. Improvement in the loss results in both
auto—personal and homeowners is the result of the Company’s efforts to obtain adequate rate increases,
maintain effective underwriting guidelines along with the discipline of adhering to these guidelines. Workers’
compensation continues to be the Company’s most volatile line of business due to the risks insured. Workers’
compensation results have been volatile both for the Company and the industry and can have a significant
adverse impact on earnings. The Company manages this exposure with conservative underwriting and rate levels
that are based on National Council of Compensation Insurance loss costs. As a result of the Company’s
conservative approach, workers’ compensation represents 3% of total earned premium.

The standard segment’s GAAP loss and LAE ratio improved 6.3 points in 2004 from 2003, despite being
impacted by the record level catastrophe losses described above. For the years 2004 and 2003, catastrophe losses
represent 7.5 and 7.3 points of this segment’s GAAP loss and LAE ratios, respectively. Hurricanes Charley,
Frances, Jeanne and Ivan accounted for 4.2 points of the 2004 total segment catastrophe loss points and CAT 88
accounted for 4.4 points of the 2003 total catastrophe points. Absent the impact of catastrophe losses in each
year, this segment’s GAAP loss and LAE ratio improved 6.4 points in 2004 from 2003.

The nonstandard segment’s GAAP loss and LAE ratio improved 5.1 points in 2004 to 70.5 from 75.6 in
2003. The 2004 and 2003 catastrophe losses represent 0.5 points and 1.4 points, respectively, of this segment’s
GAAP loss and LAE ratio. Absent the impact of catastrophe losses, this segment’s GAAP loss and LAE ratio
improved 4.2 points in 2004 from 2003. The nonstandard automobile segment typically is a more volatile line of
business in terms of higher loss frequency than the standard segment. The Company continually monitors this
segment’s underwriting performance paying particular attention to rate adequacy and risk selection in states and
agencies with unusually high written premium growth.

44

The GAAP expense ratios were 30.2% and 30.4% for the years 2004 and 2003, respectively. As noted
above, the Company ceded to Mutual in 2003 $12.8 million in earned premiums under the Stop Loss which
increased the GAAP expense ratio for 2003 by 0.4 points. For the years ended December 31, 2004 and 2003,
bonuses under the Quality Performance Bonus (“QPB”) Plan for employees accounted for 1.2 and 0.8 GAAP
expense ratio points, respectively. As of April 1, 2005, the QPB plan was amended to adjust the targeted
profitability requirement from a 100.0% statutory direct combined ratio to 98.0% and to implement an annual cap
in the amount of QPB bonus earned in any one year to 35.0% of an associate’s annual salary. Based on
improvement in the Company’s underwriting results in 2004 as compared to 2003, the Company increased its
expected 2004 Quality Performance Agreement (“QPA”) accrual as compared to 2003. QPA obligates the
Company to share a portion of the underwriting profit generated by the independent agencies’ State Auto book of
business. For the years ended December 31, 2004 and 2003, QPA bonuses accounted for 1.9 and 1.6 GAAP
expense ratio points, respectively.

Interest expense increased $3.6 million (97.3%) to $7.3 million in 2004 from 2003. This increase was the
result of an additional $85.5 million of debt, net of repayments, obtained during the last nine months of 2003. See
“Liquidity and Capital Resources—Borrowing Arrangements” for further discussion of the Company’s debt
activity in 2004 and 2003.

The consolidated effective tax rate for 2004 was 27.4% and for 2003 was 23.6%. The increase in the
effective tax rate was largely due to the increase in underwriting profit in 2004 versus 2003. Underwriting profit
is taxed at approximately 35%. The effective tax rate on net investment income in 2004 was 19.4% versus
approximately 20.0% in 2003. Late in 2003, the Company began shifting the investment portfolio to more tax
exempt investments.

LIQUIDITY AND CAPITAL RESOURCES

General

Liquidity refers to the ability of the Company to generate adequate amounts of cash to meet its needs for
both long-term and short-term cash obligations as they come due. The Company’s significant sources of cash are
premiums, investment income, investment sales and the maturity of fixed security investments. The significant
outflows of cash are payments of claims, commissions, premium taxes, operating expenses, income taxes,
dividends, interest and principal payments on debt and investment purchases. The cash outflows can vary due to
uncertainties regarding settlement of large losses or catastrophe events. As a result, the Company continually
monitors its investment and reinsurance programs to ensure they are appropriately structured to enable the
insurance subsidiaries to meet anticipated short and long-term cash requirements without the need to sell
investments to meet fluctuations in claim payments.

The Company maintains a portion of its investment portfolio in relatively short-term and highly liquid
investments to ensure the immediate availability of funds to pay claims and expenses. At December 31, 2005 and
2004, the Company had $28.7 million and $64.3 million, respectively, in cash and cash equivalents. See further
discussion regarding investments in the “Investments” and “Market Risk” sections included herein.

The Company’s insurance subsidiaries must have adequate liquidity to ensure that their cash obligations are
met. However, because the STFC Pooled Subsidiaries participate in the Pooling Arrangement, they do not have
the daily liquidity concerns normally associated with an insurance company. This is due to the fact that, under the
terms of the Pooling Arrangement, Mutual receives all premiums and pays all losses and expenses associated
with the insurance business produced by the pool participants and then settles the intercompany balances
generated by these transactions with the participating companies on a quarterly basis within 45 days following
each quarter end. When settling the intercompany balances, Mutual provides the pool participants with full credit
for the premiums written and net losses paid during the quarter and retains all receivable amounts from insureds
and agents and reinsurance recoverable on paid losses from unaffiliated reinsurers. Any receivable amounts that

45

are ultimately deemed to be uncollectible are charged-off by Mutual and allocated to the pool member on the
basis of pool participation. As a result, the Company has an off-balance sheet credit–risk related to the balances
due to Mutual from insureds, agents and reinsurers, which is offset by the unearned premium from the respective
policies. The State Auto Group’s reliance on ceded reinsurance is not significant in comparison to the State Auto
Group’s total statutory surplus or the Company’s total financial position. To minimize the risk of reinsurer
default, the State Auto Group cedes only to third-party reinsurers who are rated A- or better by A.M. Best and
also utilizes both domestic and international markets to diversify its credit risk. While the total amount due to
Mutual from policyholders and agents is significant, the individual amounts due are relatively small at the
policyholder and agency level. Based on historical data, this credit-risk exposure is not considered to be material
to the Company’s financial position, though the impact to income on a quarterly basis may be material. The State
Auto Group mitigates its exposure to this credit risk through its in-house collections unit for both personal and
commercial accounts which is supplemented by third party collection service providers. The amounts deemed
uncollectible by Mutual and allocated to the STFC Pooled Companies are included in Other Expenses in the
accompanying Statements of Income.

Net cash provided by operating activities was $226.3 million, $147.6 million and $138.0 million for 2005,
2004 and 2003, respectively. The significant sources of operating cash flows are derived from underwriting
operations and investment income. The increase in cash flows over the three year period is largely due to
improved underwriting and investment income cash flows, offset by increases in cash paid on estimated federal
income taxes, interest expense and cash contributions to the Company’s defined benefit pension plan (the
“Pension Plan”). In addition, 2005 benefited from the $54.0 million received from the January 1, 2005 Pooling
Arrangement amendment described above. Over the last three years, operating cash flows have been sufficient to
meet the operating needs of the Company while providing increased opportunities for investment. However,
should the Company’s written premium decline, the Company’s cash operating flows could be significantly
impacted requiring the Company to liquidate investments. The Company utilizes reinsurance to limit its loss
exposure and contribute to its liquidity and capital resources. See the discussion of “Reinsurance Arrangements”
included herein.

During 2005, 2004 and 2003, as permitted by regulations of the Internal Revenue Service, the Company
made cash contributions of $7.5 million, $5.0 million and $4.6 million, respectively, to the Pension Plan on
behalf of its employees. The actuarially determined contribution to the Pension Plan ranges from the minimum
amount the Company would be required to contribute to the maximum amount that would be tax deductible.
Amounts contributed in excess of the minimum are deemed voluntary while amounts in excess of the maximum
would be subject to an excise tax and may not be deductible for tax purposes. Amounts paid in each of these
three years were within the minimum and maximum funding amounts that would be deductible for tax purposes.
The actuarially determined funding amount to the Pension Plan is generally not determined until the second
quarter with respect to the contribution year, though the Company currently expects to make a cash contribution
of approximately $10.0 million during 2006 to the Pension Plan. See additional discussion regarding the
Company’s Pension Plan provided under the “Employee Benefit Plans” section included herein.

Net cash used in investing activities was $212.5 million, $130.4 million and $280.2 million for 2005, 2004

and 2003, respectively. The increase in net investing activities in 2005 over 2004 is primarily the result of:

•

•

•

a larger amount of cash and cash equivalents available to invest at the beginning of 2005 versus 2004
($64.3 million in 2005 compared to $40.0 million in 2004);

$54.0 million from the January 1, 2005 Pooling Arrangement amendment; and

the current year increase in cash provided by operating activities as described above.

A smaller amount of cash and cash equivalents available to invest at the beginning of 2004 versus 2003
($40.0 million in 2004 compared to $96.0 million in 2003), along with a decrease in cash provided by financing
activities, as compared to 2003, accounted for the decreased net investing activities during 2004. The 2003 cash
used in investing activities reflects the increase in cash flow provided by financing activities discussed below.

46

Net cash used in financing activities for 2005 was $49.4 million, which reflects:

•

State Auto Financial’s repayment of its $45.5 million line of credit with Mutual. See further discussion
provided under “Borrowing Arrangements” section included herein.

• An increase over 2004 in the Company’s payment of shareholder dividends of $6.3 million. Dividends
paid per common share for 2005 increased to $0.27 from $0.17 for the same 2004 period. Also
contributing to this increase was the expiration on July 31, 2005, of Mutual’s waiver of dividends that
would otherwise have been payable to it by State Auto Financial. Dividends paid by State Auto
Financial to Mutual in 2005 were $4.7 million versus none in 2004 and 2003. Beginning in the third
quarter of 2005, with the increased dividend rate along with Mutual’s receipt of its dividends, quarterly
dividend payments increased approximately $3.0 million.

Net cash provided by financing activities was $7.1 million and $86.2 million in 2004 and 2003, respectively.
The lower net financing activity during 2004 compared to 2003 was due to the absence of $85.5 million in net
proceeds the Company received in 2003 from the issuance of debt, discussed below. Positively impacting cash
flows during 2004 was the Company’s termination of two separate fair value hedge transactions for a cash
settlement of $3.8 million on future net swap payments. Impacting cash provided by financing activities during
2003 was State Auto Financial’s Board of Directors March 2002 decision to approve a plan to repurchase up to
1.0 million shares of its common stock from the public, which plan was extended through December 31, 2003.
During 2003, the Company repurchased 45,000 shares from the public for a total of $0.7 million.

On March 3, 2006, the Board of Directors of State Auto Financial declared a quarterly cash dividend of
$0.09 per common share, payable on March 31, 2006, to shareholders of record on March 15, 2006. This is the
59th consecutive cash dividend declared by State Auto Financial’s Board since State Auto Financial had its initial
public offering of common stock on June 28, 1991. State Auto Financial has increased cash dividends to
shareholders for thirteen consecutive years.

Borrowing Arrangements

Line of Credit with Mutual

In 1999, State Auto Financial entered into a line of credit agreement with Mutual for $45.5 million in
conjunction with its stock repurchase program in effect at that time. The entire principal amount was due no later
than December 31, 2005, which State Auto Financial repaid in its entirety on December 27, 2005. This
repayment was substantially funded through dividends from State Auto Financial’s insurance subsidiaries. The
interest rate under this line of credit was 3.50% and 2.25% for 2005 and 2004, respectively.

Credit Agreement

In November 2005, State Auto Financial entered into a Credit Agreement (the “Credit Agreement”) with a
syndicate of lenders. The Credit Agreement provides for a $100.0 million five-year unsecured revolving credit
facility (the “Credit Facility”). During the term of the Credit Facility, State Auto Financial has the right to
increase the total facility amount by $25.0 million, up to a maximum total facility amount of $125.0 million,
provided that no event of default has occurred and is continuing. The Credit Facility is available for general
corporate purposes, including working capital and acquisitions, and for catastrophic loss purposes. At the present
time, State Auto Financial intends to use the Credit Facility for catastrophe loss purposes. The Credit Facility
provides for interest-only payments during its term, with principal due in full at maturity. Interest is based on a
London interbank market rate or a base rate plus a calculated margin amount. In addition to requiring the
payment of a monthly fee to maintain availability of funds, the Credit Agreement contains certain covenants,
including financial covenants that require State Auto Financial to (i) maintain a minimum net worth, (ii) not
exceed a certain debt to capitalization ratio and (iii) not go below a certain fixed charge coverage ratio. State
Auto Financial did not borrow any funds under the Credit Agreement in 2005. As of December 31, 2005, State
Auto Financial was in compliance with all of its covenants under the Credit Agreement.

47

The Credit Facility replaced State Auto Financial’s structured contingent financing arrangement which
expired on November 9, 2005. State Auto Financial believes that the Credit Facility provides it with greater
flexibility than the structured contingent financing arrangement. Under this structured contingent financing
arrangement, State Auto Financial would have been provided with up to $100.0 million of funding for
reinsurance purposes if the State Auto Group incurred catastrophe losses in excess of $120.0 million. In the event
of an applicable catastrophe loss, State Auto Financial would have sold redeemable preferred shares to a special
purpose company (“SPC”), which would have borrowed the money necessary for such purchase from a syndicate
of lenders. State Auto Financial would then have contributed to State Auto P&C the funds received from the sale
of its preferred shares, thereby preserving the statutory surplus of State Auto P&C. State Auto P&C would have
used the contributed capital to pay its direct catastrophe losses and losses assumed under the intercompany
catastrophe reinsurance agreement. State Auto Financial was obligated to repay SPC (which would repay the
lenders) by redeeming the preferred shares in ten semiannual installments. In the event of a default by State Auto
Financial, the obligation to repay SPC was secured by a put agreement among State Auto Financial, Mutual and
the lenders, under which Mutual would be obligated to either purchase the preferred shares from SPC or repay
SPC for the loan(s) outstanding.

Senior Notes

In 2003, State Auto Financial issued $100.0 million of unsecured senior notes due November 2013 (the
“Senior Notes”). The Senior Notes bear interest at a fixed rate of 6.25% per annum. Proceeds from the Senior
Notes were used by State Auto Financial to fund cash capital contributions to certain of State Auto Financial’s
insurance subsidiaries, to repay bank debt and for general corporate purposes. Interest on the Senior Notes is
payable May 15 and November 15. The Senior Notes are general unsecured obligations ranking senior to all
existing and future subordinated indebtedness and equal with all existing and future senior indebtedness. The
Senior Notes are not guaranteed by any of the State Auto Financial subsidiaries and thereby are effectively
subordinated to all State Auto Financial subsidiaries’ existing and future indebtedness. As of December 31, 2005,
State Auto Financial was in compliance with all of its covenants related to the Senior Notes.

Trust Securities

State Auto Financial’s Delaware business trust subsidiary (the “Capital Trust”) issued $15.0 million
liquidation amount of capital securities in 2003, due 2033. In connection with the Capital Trust’s issuance of the
capital securities and the related purchase by State Auto Financial of all of the Capital Trust’s common securities
(liquidation amount of $0.5 million), State Auto Financial has issued to the Capital Trust $15.5 million aggregate
principal amount of unsecured Floating Rate Junior Subordinated Debt Securities due 2033 (the “Subordinated
Debentures”). The sole assets of the Capital Trust are the Subordinated Debentures and any interest accrued
thereon. Interest on the Capital Trust’s capital and common securities is payable quarterly at a rate equal to the
three-month LIBOR rate plus 4.20%, adjusted quarterly. The applicable interest rates for the periods from May
2003 through December 31, 2005 ranged from 5.32% to 8.61%.

Related to the Company’s notes payable, the Company’s primary market risk exposure is to the change in
interest rates and its credit rating. See discussion regarding the Company’s credit ratings included in the “Credit
and Financial Strength Ratings” section included herein. Based upon the notes payable carrying value at
December 31, 2005, the Company has $15.5 million notes payable with variable interest and $103.2 million
notes payable with interest fixed at 6.25%, which equates to approximately 13.1% variable interest debt and
86.9% fixed interest debt. The Company’s decision to obtain fixed versus variable interest rate debt is influenced
primarily by the following factors: (a) current market interest rates, (b) anticipated future market interest rates,
(c) availability of fixed versus variable interest instruments, and (d) its currently existing notes payable fixed and
variable interest rate position.

See the Company’s contractual obligations table in the “Contractual Obligations” section included herein.

Reinsurance Arrangements

Members of the State Auto Group follow the customary industry practice of reinsuring a portion of their
exposures and paying to the reinsurers a portion of the premiums received. Insurance is ceded principally to
reduce net liability on individual risks or for individual loss occurrences, including catastrophic losses. Although
reinsurance does not legally discharge the individual members of the State Auto Group from primary liability for
the full amount of limits applicable under their policies, it does make the assuming reinsurer liable to the extent
of the reinsurance ceded.

Each member of the State Auto Group is party to working reinsurance treaties for property, casualty and
workers’ compensation lines with several reinsurers arranged through a reinsurance intermediary. Under the
property per risk excess of loss treaty, each member is responsible for the first $2.0 million of each covered loss,
and the reinsurers are responsible for 100% of the excess over $2.0 million up to $10.0 million of covered loss.
The rates for this reinsurance are negotiated annually.

The terms of the casualty excess of loss program provide that each company in the State Auto Group is
responsible for the first $2.0 million of a covered loss. The reinsurers are responsible for 90% of the excess over
$2.0 million up to $5.0 million of covered loss. Also, certain unusual claim situations involving bodily injury
liability, property damage, uninsured motorist and personal injury protection are covered by an arrangement that
provides for $10.0 million of coverage in excess of a $5.0 million retention for each loss occurrence. This layer
of reinsurance sits above the $3.0 million excess of $2.0 million arrangement. The rates for this reinsurance are
negotiated annually.

The terms of the workers’ compensation excess of loss program provide that each company in the State
Auto Group is responsible for the first $2.0 million of covered loss. The reinsurers are responsible for 100% of
the excess over $2.0 million up to $10.0 million of covered loss. Net retentions under this contract may be
submitted to the casualty excess of loss program, subject to a limit of $2.0 million per loss occurrence. The rates
for this reinsurance are negotiated annually.

In addition to the workers’ compensation reinsurance program described above, each company in the State
Auto Group is party to an agreement which provides an additional layer of excess of loss reinsurance for
workers’ compensation losses involving multiple workers. Subject to $10.0 million of retention, reinsurers are
responsible for 100% of the excess over $10.0 million up to $20.0 million of covered loss. This coverage is
subject to a “Maximum Any One Life” limit of $10.0 million. The rates for this reinsurance are negotiated
annually.

In addition, the State Auto Group has secured other reinsurance to limit the net cost of large loss events for
certain types of coverage. Included are umbrella liability losses which are reinsured up to a limit of $10.0 million
with a maximum $0.6 million retention. The State Auto Group also makes use of facultative reinsurance for
unique risk situations and participates in involuntary pools and associations in certain states.

49

The State Auto Group participates in an intercompany catastrophe reinsurance program. Under this
program, the members of the State Auto Group, on a combined basis, retain the first $40.0 million of catastrophe
losses that affect at least two individual risks. For catastrophe losses incurred by the State Auto Group up to
$80.0 million, in excess of $40.0 million, traditional reinsurance coverage is provided with a co-participation of
5%. For catastrophe losses incurred by the State Auto Group up to $100.0 million, in excess of $120.0 million, in
exchange for a premium paid by each reinsured company, State Auto P&C acts as the catastrophe reinsurer for
the State Auto Group under the terms of an intercompany catastrophe reinsurance agreement. There have been no
losses assumed under this agreement.

The Company’s actuarial department derived expected payment patterns separately for the direct loss and ALAE reserves (ALAE
defined below). Amounts include the STFC Pooled Companies net additional share of transactions assumed from Mutual through the
Pooling Agreement (see reconciliation of management’s best estimate included in the Loss Reserves section included herein). These
patterns were applied to the December 31, 2005, loss and ALAE payable to generate estimated annual incremental loss and ALAE
payments for each subsequent calendar year. These amounts are based on historical payment patterns and do not represent actual
contractual obligations. The actual payment amounts and the related timing of those payments could differ significantly from these
estimates.

Lease and other purchase obligations are allocated to the Company through the Pooling Arrangement.
Excluded from the table above are pension and postretirement benefit obligations which are described in Item 8,
of the Company’s Consolidated Financial Statements, Note 9, “Pension and Postretirement Benefit Plans.”

Regulatory Considerations

At December 31, 2005, 2004 and 2003, each of the Company’s insurance subsidiaries was in compliance

with statutory requirements relating to capital adequacy.

The National Association of Insurance Commissioners (“NAIC”) utilizes a collection of analytical tools
designed to assist state insurance departments with an integrated approach to screening and analyzing the
financial condition of insurance companies operating in their respective states. One such set of analytical tools is
12 key financial ratios that are known in the insurance industry as the “IRIS” ratios. IRIS ratios are derived from
financial statements prepared on a statutory accounting basis, which are accounting practices prescribed or
permitted by the insurance department with regulatory authority over the Company’s insurance subsidiaries. A
“defined range” of results for each ratio has been established by the NAIC for solvency monitoring. While
management utilizes each of these IRIS ratios in monitoring its operating performance on a statutory accounting
basis, of which each of the respective insurance subsidiaries operates well within the defined range for the other

50

measures, the net written premium to statutory surplus ratio (the “leverage ratio”) is monitored to ensure that
each of the Company’s insurance subsidiaries continues to operate within the “defined range” of 3.0 to 1.0. The
higher the leverage ratio, the more risk a company bears in relation to statutory surplus available to absorb losses.
In considering this range, Management also considers the distribution of net premiums between property and
liability lines of business. A company with a larger portion of net premiums from liability lines should generally
maintain a lower leverage ratio.

The statutory leverage ratios for the Company’s insurance subsidiaries at December 31, 2005, 2004 and

2003 are as follows:

The Company uses the statutory leverage ratio as there is no comparable GAAP measure.

The Company’s insurance subsidiaries pay dividends to State Auto Financial which in turn are used by State
Auto Financial to pay dividends to shareholders as well as to make principal and interest payments on debt.
Individual states limit the amount of dividends that such subsidiaries domiciled in those states can pay without
prior approval. The maximum amount of dividends that may be paid to State Auto Financial during 2006 by its
insurance subsidiaries without prior approval under current law is limited to $121.2 million, adjusted for
dividends paid by the insurance subsidiaries in the previous twelve months. State Auto Financial received
dividends of $40.5 million and $12.0 million from its insurance subsidiaries in 2005 and 2004, respectively. The
Company is required to notify the insurance subsidiaries’ respective State Insurance Commissioner within five
business days after declaration of all such dividends and at least ten days prior to payment. Additionally, the
domiciliary Commissioner of each insurer subsidiary has the authority to limit a dividend when the
Commissioner determines, based on factors set forth in the law, that an insurer’s surplus is not reasonable in
relation to the insurer’s outstanding liabilities and adequate to its financial needs. Such restrictions are not
expected to limit the capacity of State Auto Financial to meet its cash obligations.

State Auto Financial’s insurance subsidiaries are subject to regulation and supervision by the states in which
they do business. The NAIC has developed Risk-Based Capital (“RBC”) requirements. RBC attempts to relate an
individual insurance company’s statutory surplus to the risk inherent in its overall operations. RBC requires the
calculation of a ratio of total adjusted statutory capital to Authorized Control Level. Insurers with a ratio below
200% are subject to different levels of regulatory intervention and action. At December 31, 2005, the risk-based
adjusted surplus of State Auto Financial’s insurance subsidiaries ranged from 711% to 1400%.

The Company is reviewed regularly by the independent rating agencies listed in the table above. Ratings
provide a meaningful way for policyholders, agents, creditors and shareholders to compare the Company to its
competitors. The published credit ratings on the State Auto Financial Senior Notes discussed above are opinions
as to the ability of State Auto Financial to meet its ongoing obligations under the terms of the Senior Notes.
Generally, credit ratings affect the cost, type and availability of debt financing. Higher rated securities receive
more favorable pricing and terms relative to lower rated securities at the time of issue. State Auto Financial’s
Senior Notes have been rated investment grade by each agency.

The published financial strength ratings on the insurance company subsidiaries of State Auto Financial are
opinions as to the ability of those companies to meet their ongoing obligations to their policyholders. The A.M.
Best financial strength ratings influence the Company’s ability to write insurance business as agents and
policyholders generally prefer higher rated companies. Lower rated companies may be required to compete for
agents and policyholders by offering higher commissions or lower premiums and expanded coverage, or a
combination thereof. Mutual is one of only 14 companies in the United States that have received A.M. Best’s A+
or higher rating every year since 1954. The STFC Pooled Companies collectively with the Mutual Pooled
Companies are assigned a pool rating by A.M. Best while SA National is rated as a part of the total group.

The Company’s ratings are influenced by many factors including operating and financial performance, asset
quality, liquidity, financial leverage, exposure to catastrophe risks and operating leverage. At December 31,
2005, the Company’s A.M. Best and Moody’s ratings were assigned stable outlooks while the Standard and
Poor’s ratings were assigned positive outlooks.

OTHER

Investments

Overview

Stateco performs investment management services, which comprise the investment management services
segment, on behalf of the Company and Mutual and its subsidiaries. The Investment Committee of each insurer’s
Board of Directors sets investment policies to be followed by Stateco.

The primary investment objectives of the Company are to generate income, preserve capital and maintain
adequate liquidity for the payment of claims. The Company’s Investment Policy and Guidelines permit
investment in debt issues rated A, or better, by two major rating services. The Company’s fixed maturities
portfolio is composed of high quality, investment grade issues, comprised almost entirely of debt issues rated
AAA or AA. At December 31, 2005, the Company had no fixed maturity investments rated below investment
grade, nor any mortgage loans.

Despite the volatility in the equity market during 2005 and 2004, the Company continued to moderately
increase its equity portfolio investments to enhance growth of statutory surplus over the long term. Gains and
losses on the sale of equity securities are computed using the first-in, first-out method. The Company’s current
investment strategy does not rely on the use of derivative financial instruments.

The Company manages its equity portfolio by investing in a large, but manageable, number of stocks from
many different industries. This diversification across companies and industries reduces volatility in the value of
the equity portfolio. The Company invests only in stocks that currently pay a dividend. As of December 31,
2005, the Company’s equity portfolio consisted of approximately 100 different stocks. The largest single position
was 2.2% of the equity portfolio based on fair value and the top ten positions were equal to approximately 16%
of the equity portfolio. The chart below shows the industry sector breakdown of the Company’s equity portfolio
versus the S&P 500 Index based on fair value as of December 31, 2005.

The Company’s equity portfolio tends to consist of large cap, value oriented stocks. Therefore, when large
cap stocks and/or value stocks perform well the Company’s portfolio typically performs well. Conversely, when
growth stocks outperform value and/or small to mid cap stocks outperform large cap, the Company’s portfolio
does not perform as well.

At December 31, 2005 and 2004, all investments in fixed maturity and equity securities were held as
available-for-sale and therefore are carried at fair value. The unrealized holding gains or losses, net of applicable
deferred taxes, are shown as a separate component of stockholders’ equity as “accumulated other comprehensive
income” and as such are not included in the determination of net income.

The following table provides the composition of the Company’s investment portfolio at December 31, 2005

and 2004, respectively:

The Company regularly monitors its investment portfolio for declines in value that are other-than-
temporary, an assessment which requires significant management judgment regarding the evidence known. Such
judgments could change in the future as more information becomes known which could negatively impact the
amounts reported herein. Among the factors that management considers are the nature of the investment, severity
and length of decline in fair value, events impacting the issuer, overall market conditions, and the Company’s
intent and ability to hold securities until recovery. When a security in the Company’s investment portfolio has
been determined to have a decline in fair value that is other-than-temporary, the Company adjusts the cost basis
of the security to fair value. This results in a charge to earnings as a realized loss, which is not changed for
subsequent recoveries in fair value. Future increases or decreases in fair value, if not other-than-temporary, are
included in other comprehensive income.

The Company reviewed its investments at December 31, 2005, and determined no additional other-than-
temporary impairment exists in the gross unrealized holding losses, as provided in the table below, due to the
evidence that exists indicating temporary impairment. At December 31, 2005, there were no investments
reflected in the table below with an unrealized holding loss that had a fair value significantly below cost
continually for more than one year. There are no individually material securities with an unrealized holding loss
at December 31, 2005.

Expected maturities may differ from contractual maturities as the issuers may have the right to call or

prepay the obligations with or without call or prepayment penalties.

The Company participates in a securities lending program whereby certain fixed maturity and equity
securities from the Company’s investment portfolio are loaned to other institutions for short periods of time. The
Company requires collateral, equal to 102% of the market value of the loaned securities. The collateral is
invested by the lending agent, in accordance with Company’s guidelines, generating investment income, net of
applicable fees. The Company accounts for this program as a secured borrowing and records the collateral held

54

and corresponding liability to return the collateral on its balance sheet. At December 31, 2005 and 2004, the
amount of collateral held was approximately, $99.0 million and $144.7 million, respectively, and the amount of
securities lent was $96.0 million and $140.4 million, respectively.

Market Risk

At December 31, 2005, total investments at fair value comprise approximately 82.6% of the Company’s
total assets. Of the Company’s total investments, 86.0% are invested in fixed maturities, 13.6% in equity
securities and 0.4% in other invested assets. Cash and cash equivalents represent approximately 1.3% of the
Company’s total assets at December 31, 2005.

The Company’s decision to make a specific investment is influenced primarily by the following factors:
(a) investment risks; (b) general market conditions; (c) relative valuations of investment vehicles; (d) general
market interest rates; (e) the Company’s liquidity requirements at any given time; and (f) the Company’s current
federal income tax position and relative spread between after tax yields on tax-exempt and taxable fixed income
investments.

The Company’s primary market risk exposures are to changes in market prices for equity securities and
changes in interest rates and credit ratings for fixed maturity securities. The Company’s fixed income securities
are subject to interest rate risk whereby the value of the securities varies as market interest rates change. The
Company manages this risk by closely monitoring the duration of the fixed income portfolio. The duration of the
fixed maturity portfolio was approximately 5.14 and 5.23 as of December 31, 2005 and 2004, respectively. The
table below summarizes the Company’s interest rate risk and shows the effects of a parallel change in interest
rates on the fair value of the fixed income portfolio (excluding other debt securities) as of December 31, 2005:

This table summarizes only the effects that a parallel change in interest rates could have on the fixed
income portfolio. This change in rates would also change the value of the Company’s liabilities and possibly
other financial assets. The Company cautions the reader that this analysis does not take into account nonparallel
changes in interest rates. It is likely that some rates would increase or decrease more than others depending upon
market conditions at the time of the change. This nonparallel change would alter the value of the fixed income
portfolio. The analysis is also limited in that it does not take into account any actions that might be taken by the
Company in response to these changes. As a result, the actual impact of a change in interest rates and the
resulting fixed income values may differ significantly from what is shown in the table.

The Company believes that the fixed income portfolio’s exposure to credit risk is minimal as greater than
99% of the bonds owned are rated AA or better with the remaining bonds being A rated. There are no fixed
securities owned rated less than A. The Company does not intend to change its investment policy on the quality
of its fixed maturity investments. The fixed maturity portfolio is managed in a laddered-maturity style and
considers business mix and liability payout patterns to ensure adequate cash flow to meet claims as they are
presented. The Company also manages liquidity risk by maintaining sufficient cash balances, owning some
agency and U.S. Treasury securities at all times, purchasing bonds of major issuers, and purchasing bonds that
are part of a medium or large issue. The fixed income portfolio does not have any direct exposure to either
exchange rate risk or commodity risk. The Company does not rely on the use of derivative financial instruments.
To provide the Company greater flexibility in order to manage its market risk exposures, the Company
categorizes its fixed maturities as available-for-sale. The Company does not maintain a trading portfolio.

55

As of December 31, 2005, the Company’s equity portfolio had a beta of 0.98 using the S&P 500 Index as a
benchmark. Beta estimates the degree the portfolio’s price will fluctuate based on a given movement in the
market index. The table below reflects what changes might occur in the value of the equity portfolio given a
change in the S&P 500 Index:

The above analysis is limited in that it does not take into account any actions that might be taken by the
Company in response to these changes. As a result, the actual impact of a change in equity market prices and the
resulting equity values may differ significantly from what is shown in the table. By investing in mostly large cap
issues the Company hopes to limit liquidity risk in the equity portfolio. The equity portfolio does not have any
direct exposure to exchange rate risk since the Company does not hold any foreign stocks. The Company
constantly monitors the equity portfolio holdings for any credit risk issues that may arise. The Company does not
invest in any commodity futures or commodity oriented mutual funds.

Some parameters have been set by the Investment Committee to help manage the risks associated with the
investment portfolio. For the insurance subsidiaries, the maximum investment in any single note or bond is
limited to 5.0% of statutory assets, other than obligations of the U.S. government or government agencies, for
which there is no limit. Investments in equity securities are selected based on their potential for appreciation as
well as ability to continue paying dividends. The equity portfolio is diversified across industries and
concentrations in any one company or industry are limited by parameters established by the Investment
Committee of the Company’s Board of Directors. The total holding of a specific stock should not exceed 2% of
the outstanding stock and based on market value at the time of purchase, no one equity holding should exceed
5% of the total equity portfolio. Up to 15% of the equity portfolio may deviate from these requirements allowing
the Company to invest in timely special situations. Equity investments will normally be targeted to no more than
40% of total assets or 50% of statutory surplus whichever is greater. Additional information regarding the
composition of investments, along with maturity schedules regarding investments in fixed maturities at
December 31, 2005, is presented in tabular form above.

The Company’s total investments, at fair value, grew approximately 10.6% during 2005 to $1,879.9 million
at December 31, 2005, from $1,699.1 million at December 31, 2004. This growth was generated primarily from
net cash flows provided by operations, $54.0 million received from the Meridian Insurers and financing activities
which were offset by a decline on the cumulative unrealized gains on investments. The net unrealized gain on the
Company’s equity portfolio increased $0.6 million to $30.8 million at December 31, 2005, while the Company’s
net unrealized gain on its fixed maturity portfolio declined $30.2 million to $20.0 million at December 31, 2005.
Unrealized gains related to other invested assets increased $0.6 million to $0.8 million at December 31, 2005.

Employee Benefit Plans

The State Auto Group has a defined benefit pension plan and a postretirement health care plan covering
substantially all employees. Key assumptions used to determine net periodic cost and the benefit obligation at the
measurement date include the discount rate and expected long term rate of return on plan assets among other
factors. Therefore, changes in the related costs may occur in the future due to changes in assumptions.

To calculate the State Auto Group’s pension benefit obligation as of December 31, 2005, the Company used
a discount rate of 5.75% based on an evaluation of the expected future benefit cash flows of the Pension Plan
used in conjunction with the Citigroup Pension Discount Curve (formerly Salomon Brothers Pension Discount
Curve) at the measurement date. A lower discount rate results in, all else equal, a higher present value of the
benefit obligation. The Company selected an expected long-term rate of return on its plan assets of 9.0% by
considering the mix of investments, stability of investment portfolio along with actual investment experience

56

during the lifetime of the plan. To calculate the net periodic pension cost for the year ended December 31, 2005,
a discount rate of 6.50% and an expected long-term rate of return on plan assets of 9.0% were used.

The selected discount rate of 5.75% is a reduction of 0.75 points from the 6.50% rate used in the previous
year which had the effect of increasing the pension benefit obligation at December 31, 2005 and related
unrecognized net loss by approximately $23.2 million. Unrecognized losses of approximately $82.4 million are
being recognized over approximately a 12 year period, which represents the average future service period of
active participants. Unrecognized gains and losses arise from several factors including expected to actual
demographic changes, assumption changes in the obligations and from the difference between expected and
actual returns on plan assets. These unrecognized losses will be systematically recognized as an increase in future
net periodic pension expense in accordance with FASB Statement 87, “Employers Accounting for Pensions”
(“SFAS 87”).

Key assumptions used in determining the amount of the benefit obligation and related periodic cost
recognized for postretirement benefits other than pensions under FASB Statement 106, “Employers Accounting
for Postretirement Benefits Other Than Pensions” (“SFAS 106”), include the discount rate and the assumed
health care cost trend rate. To calculate the State Auto Group’s benefit obligation as of December 31, 2005, the
Company decreased its selected discount rate by 0.75 points to 5.75% from the 2004 discount rate to match the
anticipated stream of future benefit payments. The Company assumes that the relative increase in health care
costs will generally trend downward over the next several years, reflecting assumed increases in efficiency in the
health care system and cost containment initiatives. At December 31, 2005, the expected rate of increase in future
health care costs was 10% for 2006, trending down 1% per year to 5% thereafter. If the assumed future health
care cost trend rate had been increased or decreased by one percentage point, the Company’s accumulated
obligation as of 2005 would have increased by $7.3 million and decreased by $6.3 million, respectively.

On December 8, 2003, the Medicare Prescription Drug, Improvement and Modernization Act of 2003 (the
“Act”) was signed into law. The Act expanded Medicare to include, for the first time, coverage for prescription
drugs. In May of 2004, the FASB issued FASB Staff Position 106-2 “Accounting and Disclosure Requirements
Related to the Medicare Prescription Drug, Improvement and Modernization Act of 2003” (“FSP 106-2”). FSP
106-2 provided guidance on accounting for the effects of the Act for employers that sponsor postretirement
health care plans that provide drug benefits. The Company and its actuarial advisors completed a review of its
plan provisions and concluded that the benefits provided by its plan are actuarially equivalent to Medicare Part D
and will be entitled to the subsidy. The Company determined that the enactment of the Act was not a significant
event and incorporated the effect of the Act in the most recent measurement date pursuant to FSP 106-2.

The actuarial assumptions used by the Company in determining its pension and postretirement benefit
obligations may differ materially from actual results due to changing market and economic conditions, higher or
lower turnover and retirement rates or longer or shorter life spans of participants. While the Company believes
that the assumptions used are appropriate, differences in actual experience or changes in assumptions may
materially affect the Company’s financial position or results of operations.

(1) December 31, 2004 reserve balances have been adjusted for comparison purposes to reflect the loss and loss expense reserves assumed

by the Company on January 1, 2005 from the Pooling Arrangement amendment discussed above.

(2) Calculated based on December 31, 2005 change from January 1, 2005.

As provided in the above table, total net losses and loss expenses payable increased 2.9% from January 1,
2005 to December 31, 2005. The reserve changes year-to-date are primarily attributable to property lines of
insurance, where the increases are driven by catastrophe losses. In particular, hurricane Katrina resulted in
unprecedented conditions impacting the logistics of adjusting and paying claims. Consequently, much of
Katrina’s losses remain in reserve status until the settlement process can move forward. In addition, hurricane
Wilma impacted fourth quarter results which also accounts for outstanding reserves in these same lines of
business. Outside of the property lines, the reserve level changes are consistent with the exposure level changes
at the product level. The current year development of the prior years’ ultimate liability does not reflect any
changes in the Company’s fundamental claims reserving practices.

The Company’s internal actuarial staff conducts quarterly reviews of projected loss development
information to assist management in making estimates of reserves for ultimate losses and loss expenses payable.
Several factors are considered in estimating ultimate liabilities including consistency in relative case reserve
adequacy, consistency in claims settlement practices, recent
legal developments, historical data, actuarial
projections, accounting projections, exposure growth, current business conditions, catastrophe developments, and
late reported claims. In addition, reasonableness tests are performed on measures of claim severity, loss ratio and
trend factors, all of which are implicit in the liability estimates.

Losses and loss expenses payable is management’s best estimate (“MBE”) at a given point in time of what
the Company expects to pay claimants, based on known facts, circumstances and historical trends. Reserves for
reported losses are established by the Company’s claim division on either a case-by-case or formula basis
depending on the type and circumstances of the loss. The case-by-case reserve amounts are determined based on
the Company’s reserving practices, which take into account the type of risk, the circumstances surrounding each
claim and policy provisions relating to types of loss. The objective of the claims division is to establish ultimate
case reserves that are sufficient, but not excessive. The formula reserves are based on historical data for similar
claims with provision for trend changes caused by inflation. Loss and loss expense reserves for incurred claims

58

that have not yet been reported (“IBNR”) are estimated based on many variables including historical and
statistical information, inflation, legal developments, storm loss estimates, and economic conditions. Case and
formula basis loss reserves are reviewed on a regular basis, and as new data becomes available, estimates are
updated resulting in adjustments to loss reserves. Generally, reported losses initially reserved on a formula basis
and not settled after six months are case reserved at that time. Although management uses many resources to
calculate reserves, there is no method for determining the exact ultimate liability.

Management establishes a reserve for loss adjustment expenses contemplating functions and costs that are
not attributable to a specific claim, which is called Unallocated Loss Adjustment Expense (“ULAE”). Historical
ratios of paid ULAE to paid losses are developed, and then imposed on the current outstanding reserves. The
method uses a traditional assumption that 50% of the expenses are realized when the claim is open, and the other
50% are incurred as the loss payments are made. The method also assumes that the underlying claims process
and mix of business do not change drastically over time.

MBE for SA National and the STFC Pooled Companies’ share of the Pooled Companies’ losses and
allocated loss expense reserve (“Loss and ALAE Reserve”) at December 31, 2005 is $748.4 million, compared
with an actuarial point estimate of $721 million that is within a projected range of $681 million to $763 million.
These values presented are on a direct basis, gross of salvage and subrogation recoverable, and before
reinsurance, except for the STFC Pooled Companies’ participation in the inter-company Pooling Arrangement.
Therefore, the Company cautions the reader that these values cannot be compared to other loss and loss expenses
payable tables included elsewhere within this Form 10-K. Reserve ranges provide a quantification of the
variability in the reserve projections, which is often referred to as the standard deviation or error term, while the
point estimates establish a mean, or expected value for the ultimate reserve. MBE of loss reserves considers the
actuarial point estimate and expected variation to establish an appropriate position within the range.

The potential impact of loss reserve variability on net income is quantifiable using the range end points and
carried reserve amounts listed above. For example, if ultimate losses reach the high point of $763 million, the
reserve increase of $15 million is an after-tax decrease of $9.8 million on net income. Likewise, should losses
decline to the low end of $681 million, the $67 million reserve decrease would add $43.6 million of after-tax net
income.

An important assumption underlying the reserve estimation methods for the major casualty lines is that the
loss cost trends implicitly built into the loss and ALAE patterns will continue into the future. To estimate the
sensitivity of reserves to an unexpected change in inflation, projected calendar year payment patterns were
applied to the December 31, 2005, other liability loss and ALAE payable to generate estimated annual
incremental loss and ALAE payments for each subsequent calendar year. Then, for purposes of sensitivity
testing, an additional annual loss cost trend of two percent was added to the trend implicitly embedded in the
estimated payment pattern, and revised incremental loss and ALAE payments were calculated. This type of
inflationary jump could arise from a variety of sources including tort law changes, development of new medical
procedures, social inflation, and other inflationary changes in costs beyond assumed levels.

The estimated cumulative impact that this additional, unexpected two percent increase in the loss cost trend
would have on our results of operations over the lifetime of the underlying claims in other liability is an increase
of $9.3 million on reserves, or a $6.1 million after-tax reduction (assuming a tax rate of 35%) to net income.
Inflation changes have much more impact on the longer tail commercial lines like other liability and workers’
compensation, and much less impact on the shorter tail personal lines’ reserves.

(1) ALAE are those costs that can be related to a specific claim, which may include attorney fees, external claims adjusters and investigation
costs, among others. ULAE are those costs incurred in settling claims, such as in-house processing costs, for which no identification can
be made to specific claims. ALAE and ULAE comprise the loss expense portion of the total loss and loss expenses payable.

The property and casualty industry has had significant loss experience from claims related to asbestos,
environmental remediation, product liability, mold and other mass torts. Asbestos reserves are $3.7 million, and
environmental reserves are $5.5 million, for a total of $9.2 million, or 1.3% of net losses and loss expenses
payable. Because the Company has insured primarily product retailers and distributors, not manufacturers,
incurred losses have not been significant from asbestos and environmental claims activity.

The risks and uncertainties inherent in the estimates include, but are not limited to, actual settlement
experience being different from historical data and trends, changes in business and economic conditions, court
decisions creating unanticipated liabilities, ongoing interpretation of policy provisions by the courts, inconsistent
decisions in lawsuits regarding coverage and additional information discovered before settlement of claims. The
Company’s results of operations and financial condition could be impacted, perhaps significantly, in the future if
the ultimate payments required to settle claims vary from the liability currently recorded.

New Accounting Standards

In September 2005, the Accounting Standards Executive Committee issued Statement of Position 05-1,
“Accounting by Insurance Enterprises for Deferred Acquisition Costs in Connection With Modifications or
Exchanges of Insurance Contracts” (“SOP 05-1”), which is to be effective for fiscal years beginning after
December 15, 2006, with earlier adoption encouraged. SOP 05-1 provides guidance on accounting for deferred
acquisition costs on internal replacements of insurance contracts that are modifications to product features that
occur by the exchange of a contract for a new contract. Insurance contracts issued by the Company include
nonintegrated contract features as defined in SOP 05-1, or those that provide coverage that is underwritten and
priced only for that incremental insurance coverage and do not result in reunderwriting or repricing of other
components of the contract. Nonintegrated contract features do not change the existing base contract and do not
require further evaluation under SOP 05-1. Given the nature of the policies written, the impact of SOP 05-1 upon
implementation is not expected to be material.

In May 2005, the FASB issued FASB Statement 154, “Accounting Changes and Error Corrections” (“SFAS
154”) which replaces APB Opinion 20, “Accounting Changes” (“APB 20”) and FASB Statement 3, “Reporting
Accounting Changes in Interim Financial Statements” (“SFAS 3”). SFAS 154 changes the requirements for the
accounting for and reporting of a change in accounting principle. SFAS 154 applies to all voluntary changes in
accounting principle. It also applies to changes required by an accounting pronouncement in the unusual instance
that the pronouncement does not include specific transition provisions. SFAS 154 requires voluntary changes in
accounting principles be recognized retrospectively to prior periods’ financial statements, rather than recognition
in the net income of the current period. Retrospective application requires restatement of prior period financial

61

statements as if that accounting principle had always been used. SFAS 154 carries forward without change the
guidance contained in APB 20 for reporting the correction of an error in previously issued financial statements
and a change in accounting estimate. The provisions of SFAS 154 are effective for accounting changes and
corrections of errors made in fiscal years beginning after December 15, 2005. The Company does not believe
SFAS 154 will have a material impact on the financial position or results of operations of the Company.

In December 2004, the FASB issued FASB Statement 123(R), “Share-Based Payment” (“SFAS 123(R)”),
which is a revision of SFAS 123. SFAS 123(R) supersedes APB 25 and amends FASB Statement 95, “Statement
of Cash Flows” (“SFAS 95”). SFAS 123(R) originally required adoption no later than July 1, 2005. In April
2005, the Securities and Exchange Commission (“SEC”) issued a release that amended the compliance dates for
SFAS 123(R). Under the SEC’s new rule, the Company will be required to apply SFAS 123(R) as of January 1,
2006.

Generally, the approach in SFAS 123(R) requires all share-based payments to employees, including grants
of employee stock options, to be recognized in the income statement based on their fair values. Pro-forma
disclosure is no longer an alternative. SFAS 123(R) provides two alternative methods of adoption: the modified
prospective transition or the modified retrospective transition. Under the modified prospective method, unvested
stock based awards, that were granted prior to adoption, will continue to be accounted for in accordance with
SFAS 123 except the compensation cost attributable to the unvested portion of the awards must be recognized in
the income statement. Awards that are vested will not be recognized in the income statement. Under the modified
retrospective method, prior periods are restated by recognizing compensation cost in the amounts previously
reported in the pro-forma footnote disclosures under SFAS 123. Effective January 1, 2006, the Company has
elected to adopt the fair-value-based method of accounting for share based payments using the modified
prospective method.

As permitted by SFAS 123, the Company currently accounts for share-based payments to employees using
APB 25’s intrinsic value method and, as such, generally recognizes no compensation cost for employee stock
options. Accordingly, the adoption of SFAS 123(R)’s fair value method will have a significant impact on the
Company’s result of operations, although it will have no impact on overall financial position. The impact of
adoption of SFAS 123(R) cannot be predicted at this time because it will be dependent on the levels and types of
share-based payments granted in the future (see Note 12 for a description of share-based awards eligible under
the Company’s Equity Incentive Compensation Plan and Outside Directors Restricted Share Unit Plan approved
by shareholders in 2005). However, had the Company adopted SFAS 123(R) in prior periods, the impact of that
standard would have approximated the impact of SFAS 123 as described in the disclosure of pro forma net
income and earnings per share in Note 1k. SFAS 123(R) also requires that the benefits of tax deductions in
excess of recognized compensation cost be reported as a financing cash flow, rather than as an operating cash
flow as required under current literature. This requirement will reduce net operating cash flows and increase net
financing cash flows in periods after adoption. While the Company cannot estimate what those amounts will be
in the future (because they depend on, among other things, when employees exercise stock options), the amount
of operating cash flows recognized in prior periods for such excess tax deductions were $1.8 million,
$2.3 million and $2.1 million in 2005, 2004 and 2003, respectively.

Currently, under SFAS 123 for pro-forma disclosure, the Company uses the Black-Scholes-Merton formula
to estimate the value of stock options granted to employees and will continue to use this acceptable option
valuation model upon the required adoption of SFAS 123(R) on January 1, 2006. Under SFAS 123, the Company
recognized compensation cost over the explicit service vesting period and will continue to do so for share-based
awards granted prior to the adoption of SFAS 123(R). Upon adoption of SFAS 123(R), the compensation cost
attributable to an award granted to an employee who becomes eligible to retire prior to the end of the vesting
period will be recognized over the period until the earliest date of eligible retirement. Had compensation expense
been accelerated due to retirement eligibility, pro-forma stock compensation expense, net of tax would have been
$4.2 million, $2.9 million and $2.3 million in 2005, 2004 and 2003, respectively.

Impact of Significant External Factors

Inflation can have a significant impact on property and casualty insurers because premium rates are
established before the amount of losses and loss expenses are known. When establishing rates, the Company
attempts to anticipate increases from inflation subject to the limitations of modeling economic variables. General
inflation, as measured by the CPI, has been relatively modest over the last several years; however, price inflation
on the goods and services purchased by insurance companies in settling claims has been steadily increasing. In
particular, repair costs for homes, autos, and commercial buildings, and medical care costs, have risen
disproportionately over the last few years. Costs for building materials typically rise dramatically following
substantial natural catastrophes such as the industry experienced in Florida and adjacent states in 2004 and in
Mississippi and Alabama in 2005. The Company continues to adjust its pricing projections as loss cost trends
change in order to ensure premiums keep pace with inflation in all lines of business.

The Company considers inflation when estimating liabilities for losses and loss expenses, particularly for
claims having a long period between occurrence and settlement. The liabilities for losses and loss expenses are
management’s best estimates of the ultimate net cost of underlying claims and expenses and are not discounted
for the time value of money. In times of high inflation, the normally higher yields on investment income may
partially offset potentially higher claims and expenses.

Included in the “Loss Reserves” section,

the Company has offered a description of certain factors
management considers in estimating the ultimate liability for losses and loss expenses. With respect to the auto
line of business, which represents almost half of the Company’s total reserves, perhaps the most significant
external variable is legal developments. Court decisions, as discussed below, have a significant impact on the
property and casualty insurance industry. Some of these decisions have a more prospective effect as, for
example, when contract provisions relating to third party coverages are construed in ways not anticipated by the
Company. Other court decisions may have more of a retroactive effect which may be seen more clearly in the
auto insurance line. Auto insurance tends to be a line of business more regulated by statutes; consequently, the
courts tend to have more of an opportunity to construe and apply those statutes to existing contracts. Uninsured
motorists and underinsured motorists (collectively “UM”) are statutory coverages in almost every state where the
Company does business. When courts of appeal construe UM statutes adversely to the Company and the
industry, the effect of that decision is typically retroactive, because, legally speaking, when the court interprets a
statute it is as though the statute was always construed in the manner that the court determined. This retroactive
effect is exacerbated in UM cases (and other first party coverage cases) because the statute of limitations
applicable to UM claims and other first party coverages can be as long as 15 years. Claims that had been closed
or not even presented, going back as long as fifteen years, can be re-born by an adverse court decision. The
Company considers the impact of adverse court decisions of which it has become aware when it sets ultimate loss
and LAE reserves for auto insurance as well as other lines to the extent those lines may be retroactively affected
by such matters.

The effect of court decisions is also apparent in the commercial lines of coverages such as commercial
multi-peril and other liability and products liability. Courts can expand coverage or void exclusions which can
increase the Company’s exposure to claims. Some of these third party claims may still be brought within the
statute of limitations applicable to such third party claims and expose the Company to some retroactive liabilities.
These liabilities are sought to be addressed by the ultimate loss and LAE reserve that is the Company’s estimate
of loss and loss expenses payable.

It is not feasible to quantify the impact of judicial decisions that may have retroactive effect because the
Company cannot foresee, among the range of issues that are litigated every day in courts in each state in which
the Company does business, which cases will be decided adversely and how such decisions will actually apply to
the Company.

63

The reserve estimates do not contemplate substantial loss from any mass torts, including those already listed
above, or others not known at this time. In addition, there is no provision in the reserves for a major retroactive
expansion of coverage through judicial interpretation. If these assumptions prove to be incorrect, ultimate
liabilities could increase substantially. The Company’s Claims, Underwriting and Actuarial staff track separately
all claims within the family of mass torts, and respond accordingly as information becomes known.

Premium rates are actuarially determined to enable an insurance company to generate an underwriting
profit. These rates contemplate a certain level of risk. The courts may modify, in a number of ways, the level of
risk which insurers had expected to assume including eliminating exclusions, multiplying limits of coverage,
creating rights for policyholders not intended to be included in the contract and interpreting applicable statutes
expansively to create obligations on insurers not originally considered when the statute was passed. Courts have
also undone legal reforms passed by legislatures, which reforms were intended to reduce a litigant’s rights of
action or amounts recoverable and so reduce the costs borne by the insurance mechanism. These court decisions
can adversely affect an insurer’s profitability. They also create pressure on rates charged for coverages adversely
affected, and this can cause a legislative response resulting in rate suppression that can adversely affect an
insurer. The Company may also be adversely affected by regulatory actions on matters within the jurisdiction of
the various insurance departments where the Company does business or has entities domiciled.

successor, the Terrorism Risk Insurance Extension Act of 2005 (“TRIEA”) (collectively, the “Terrorism Act”) in

Report of Independent Registered Public Accounting Firm

To the Board of Directors and Stockholders of
State Auto Financial Corporation

We have audited the accompanying consolidated balance sheets of State Auto Financial Corporation and
subsidiaries as of December 31, 2005 and 2004, and the related consolidated statements of income, stockholders’
equity and cash flows for each of the three years in the period ended December 31, 2005. Our audits also
included the financial statement schedules listed in the Index at Item 15(a)(2). These financial statements and
schedules are the responsibility of the Company’s management. Our responsibility is to express an opinion on
these financial statements and schedules based on our audits.

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

In our opinion, the financial statements referred to above present fairly, in all material respects, the
consolidated financial position of State Auto Financial Corporation and subsidiaries at December 31, 2005 and
2004, and the consolidated results of their operations and their cash flows for each of the three years in the period
ended December 31, 2005, in conformity with U.S. generally accepted accounting principles. Also, in our
opinion, the related financial statement schedules, when considered in relation to the basic financial statements
taken as a whole, present fairly in all material respects the information set forth therein.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board
(United States), the effectiveness of State Auto Financial Corporation’s internal control over financial reporting
as of December 31, 2005, based on criteria established in Internal Control—Integrated Framework issued by the
Committee of Sponsoring Organizations of the Treadway Commission, and our report dated March 1, 2006
expressed an unqualified opinion thereon.

Report of Independent Registered Public Accounting Firm

To the Board of Directors and Stockholders of
State Auto Financial Corporation

We have audited management’s assessment, included in the accompanying Management’s Annual Report
on Internal Control Over Financial Reporting, that State Auto Financial Corporation maintained effective internal
control over financial reporting as of December 31, 2005, based on criteria established in Internal Control—
Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (the
COSO criteria). State Auto Financial Corporation’s management is responsible for maintaining effective internal
control over financial reporting and for its assessment of the effectiveness of internal control over financial
reporting. 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 procedures as we considered necessary in the circumstances. We believe that our audit provides a
reasonable basis for our opinion.

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

Because of its inherent limitations, internal control over financial reporting may not prevent or detect
misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that
controls may become inadequate because of changes in conditions, or that the degree of compliance with the
policies or procedures may deteriorate.

In our opinion, management’s assessment that State Auto Financial Corporation maintained effective
internal control over financial reporting as of December 31, 2005, is fairly stated, in all material respects, based
on the COSO criteria. Also, in our opinion, State Auto Financial Corporation maintained, in all material respects,
effective internal control over financial reporting as of December 31, 2005, based on the COSO criteria.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board
(United States), the consolidated balance sheets of State Auto Financial Corporation as of December 31, 2005
and 2004, and the related consolidated statements of income, stockholders’ equity and cash flows for each of the
three years in the period ended December 31, 2005, and our report dated March 1, 2006 expressed an unqualified
opinion thereon.

b. Description of Business

The Company, through State Auto P&C, Milbank, Farmers and SA Ohio, provides standard personal and
commercial insurance to its policyholders. The Company’s principal lines of business include personal and
commercial automobile, homeowners, commercial multi-peril, workers’ compensation, general liability and fire
insurance. SA National provides nonstandard automobile insurance. State Auto P&C, Milbank, Farmers, SA
Ohio and SA National operate primarily in the central and eastern United States, excluding New York, New
Jersey and the New England states, through an independent insurance agency system. State Auto P&C, Milbank,
Farmers, SA Ohio and SA National are chartered and licensed as property and casualty insurers in the states of
South Carolina, South Dakota, Iowa and Ohio (SA Ohio and SA National), respectively, and are licensed in
various other states. As such, they are subject to the regulations of the applicable Departments of Insurance of
their respective states of domicile (the “Departments”) and the regulations of each state in which they operate.
These property and casualty insurance companies undergo periodic financial examination by the Departments
and insurance regulatory agencies of the states that choose to participate. A large portion of the Company’s
revenues are derived from a reinsurance pooling agreement with Mutual. The nature of the underlying policies
and geographical distribution of Mutual’s underwriting activity is similar to the Company.

Through State Auto P&C, the Company provides management and operation services under management

agreements for all insurance and non-insurance affiliates.

Through Stateco, the Company provides investment management services to affiliated companies.

The Company, through S.I.S., develops and sells software for the processing of insurance transactions,
database management for insurance agents and electronic interfacing of information between insurance

companies and agencies. S.I.S. sells services and products to insurance agencies and nonaffiliated insurers and
their agencies. S.I.S. also delivers services and sells products to affiliated entities.

518 PML, an Ohio limited liability company, was formed to engage in the business of owning and leasing

real and personal property to the Company’s affiliates.

c. Basis of Presentation

The consolidated financial statements have been prepared in conformity with accounting principles
generally accepted in the United States, which vary in certain respects from statutory accounting principles
followed by State Auto P&C, Milbank, Farmers, SA Ohio and SA National that are prescribed or permitted by
the Departments.

In preparing the consolidated financial statements, management

is required to make estimates and
assumptions that affect the reported amounts of assets and liabilities as of the date of the balance sheet, revenues
and expenses for the period then ended, and the accompanying notes to the financial statements. Such estimates
and assumptions could change in the future as more information becomes known which could impact the
amounts reported and disclosed herein.

Material estimates that are particularly susceptible to significant change in the near term relate to the
determination of losses and loss expenses payable. In connection with the determination of this estimate,
management uses historical data, current business conditions and assumptions about future conditions to
formulate estimates of the ultimate cost
to
uncertainties for various reasons. The Company’s results of operations and financial condition could be
materially impacted in future periods should the ultimate payments required to settle claims vary from the
amount of the liability currently provided.

to settle claims. These estimates by their nature are subject

Certain items in the prior period consolidated financial statements have been reclassified to conform to the

2005 presentation.

d. Investments

All investments in fixed maturity and equity securities are classified as available-for-sale and, therefore, are
carried at fair value. The unrealized holding gains or losses, net of applicable deferred taxes, are shown as a
separate component of stockholders’ equity as “accumulated other comprehensive income” and as such are not
included in the determination of net income. Realized gains and losses on the sale of investments are computed
using the first-in, first-out method.

The Company regularly monitors its investments that have fair values less than cost or amortized cost for
signs of other-than-temporary impairment. Among the factors that management considers are market conditions,
the amount, timing and length of decline in fair value, events impacting the issuer and the Company’s positive
intent and ability to hold the security until anticipated recovery or maturity. When a decline in value is deemed to
be other-than-temporary, the investment cost is written down to fair value on the date the determination is made
and a realized loss is recorded. The cost is not adjusted for any subsequent recovery in fair value.

e. Cash Equivalents

The Company considers all highly liquid debt instruments with a maturity of three months or less to be cash

equivalents.

f. Deferred Policy Acquisition Costs

Acquisition costs, consisting of commissions, premium taxes and certain underwriting expenses that relate
to and vary with the production of new and renewal property and casualty business, are deferred and amortized
ratably over the contract period. The method followed in computing deferred policy acquisition costs limits the
amount of such deferred costs to their estimated realizable value. In determining estimated realizable value, the
computation gives effect to the premium to be earned, related investment income, losses and loss expenses to be
incurred, and certain other costs expected to be incurred as premium is earned. These amounts are based on
estimates and accordingly, the actual realizable value may vary from the estimated realizable value. Net deferred
policy acquisition costs for the year ended December 31, are:

g. Federal Income Taxes

The Company files a consolidated federal income tax return, and pursuant to a written tax sharing
agreement, each entity within the consolidated group pays its share of federal income taxes based on separate
return calculations.

Income taxes are accounted for using the liability method. Using this method, deferred tax assets and
liabilities are determined based on differences between financial reporting and tax bases of assets and liabilities
and are measured using the enacted tax rates and laws that will be in effect when the differences are expected to
reverse.

h. Losses and Loss Expenses Payable

Losses and loss expenses payable are based on formula and case-basis estimates for reported claims and on
estimates, based on experience and perceived trends, for unreported claims and loss expenses. The liability for
unpaid losses and loss expenses, net of estimated salvage and subrogation recoverable of $28.3 million and $27.2
million at December 31, 2005 and 2004, respectively, has been established to cover the estimated ultimate cost of
insured losses. The amounts are necessarily based on estimates of future rates of inflation and other factors, and
accordingly, there can be no assurance that the ultimate liability will not vary materially from such estimates.
The estimates are continually reviewed and adjusted as necessary; such adjustments are included in current
operations (see Note 4). Anticipated salvage and subrogation is estimated using historical experience. As such,
losses and loss expenses payable represent management’s best estimate of the ultimate liability related to
reported and unreported claims.

i. Premium

Premiums are recognized as earned in proportion to the insurance protection provided using the monthly pro
rata method over the contract period. Unearned premiums represent the portion of premiums written relative to
the unexpired terms of coverage.

j. Other Comprehensive Income

Comprehensive income is defined as all changes in an enterprise’s equity during a period other than those
resulting from investments by owners and distributions to owners. Comprehensive income includes net income
and other comprehensive income. Other comprehensive income includes all other non-owner related changes to
equity and includes net unrealized gains and losses on available-for-sale fixed maturities, equity securities, other
invested assets and derivative instruments, adjusted for deferred federal income taxes.

k. Stock Compensation

The Company follows Accounting Principles Board Opinion 25, “Accounting for Stock Issued to
Employees” (“APB 25”) and related Interpretations in accounting for its employee and director share based
awards using the intrinsic value method to account for stock-based compensation. Had compensation cost for the
Company’s plans been determined based on the fair values at the grant dates consistent with the method of SFAS
123, “Accounting for Stock-Based Compensation” (“SFAS 123”), the Company’s pro-forma net earnings and net
earnings per share information would have been as follows:

l. New Accounting Standards

In September 2005, the Accounting Standards Executive Committee issued Statement of Position 05-1,
“Accounting by Insurance Enterprises for Deferred Acquisition Costs in Connection With Modifications or
Exchanges of Insurance Contracts” (“SOP 05-1”), which is to be effective for fiscal years beginning after
December 15, 2006, with earlier adoption encouraged. SOP 05-1 provides guidance on accounting for deferred

74

STATE AUTO FINANCIAL CORPORATION AND SUBSIDIARIES
(a majority-owned subsidiary of State Automobile Mutual Insurance Company)

Notes to Consolidated Financial Statements, Continued

acquisition costs on internal replacements of insurance contracts that are modifications to product features that
occur by the exchange of a contract for a new contract. Insurance contracts issued by the Company include
nonintegrated contract features as defined in SOP 05-1, or those that provide coverage that is underwritten and
priced only for that incremental insurance coverage and do not result in reunderwriting or repricing of other
components of the contract. Nonintegrated contract features do not change the existing base contract and do not
require further evaluation under SOP 05-1. Given the nature of the policies written, the impact of SOP 05-1 upon
implementation is not expected to be material.

In May 2005, the FASB issued FASB Statement 154, “Accounting Changes and Error Corrections” (“SFAS
154”) which replaces APB Opinion 20, “Accounting Changes” (“APB 20”) and FASB Statement 3, “Reporting
Accounting Changes in Interim Financial Statements” (“SFAS 3”). SFAS 154 changes the requirements for the
accounting for and reporting of a change in accounting principle. SFAS 154 applies to all voluntary changes in
accounting principle. It also applies to changes required by an accounting pronouncement in the unusual instance
that the pronouncement does not include specific transition provisions. SFAS 154 requires voluntary changes in
accounting principles be recognized retrospectively to prior periods’ financial statements, rather than recognition
in the net income of the current period. Retrospective application requires restatement of prior period financial
statements as if that accounting principle had always been used. SFAS 154 carries forward without change the
guidance contained in APB 20 for reporting the correction of an error in previously issued financial statements
and a change in accounting estimate. The provisions of SFAS 154 are effective for accounting changes and
corrections of errors made in fiscal years beginning after December 15, 2005. The Company does not believe
SFAS 154 will have a material impact on the financial position or results of operation of the Company.

In December 2004, the FASB issued FASB Statement 123(R), “Share-Based Payment” (“SFAS 123(R)”),
which is a revision of SFAS 123. SFAS 123(R) supersedes APB 25 and amends FASB Statement 95, “Statement
of Cash Flows” (“SFAS 95”). SFAS 123(R) originally required adoption no later than July 1, 2005. In April
2005, the Securities and Exchange Commission (“SEC”) issued a release that amended the compliance dates for
SFAS 123(R). Under the SEC’s new rule, the Company will be required to apply SFAS 123(R) as of January 1,
2006.

Generally, the approach in SFAS 123(R) requires all share-based payments to employees, including grants
of employee stock options, to be recognized in the income statement based on their fair values. Pro-forma
disclosure is no longer an alternative. SFAS 123(R) provides two alternative methods of adoption: the modified
prospective transition or the modified retrospective transition. Under the modified prospective method, unvested
stock based awards, that were granted prior to adoption, will continue to be accounted for in accordance with
SFAS 123 except the compensation cost attributable to the unvested portion of the awards must be recognized in
the income statement. Awards that are vested will not be recognized in the income statement. Under the modified
retrospective method, prior periods are restated by recognizing compensation cost in the amounts previously
reported in the pro-forma footnote disclosures under SFAS 123. Effective January 1, 2006, the Company has
elected to adopt the fair-value-based method of accounting for share-based payments using the modified
prospective method.

As permitted by SFAS 123, the Company currently accounts for share-based payments to employees using
APB 25’s intrinsic value method and, as such, generally recognizes no compensation cost for employee stock
options. Accordingly, the adoption of SFAS 123(R)’s fair value method will have a significant impact on the
Company’s result of operations, although it will have no impact on overall financial position. The impact of
adoption of SFAS 123(R) cannot be predicted at this time because it will be dependent on the levels and types of
share-based payments granted in the future (see Note 12 for a description of share-based awards eligible under

75

STATE AUTO FINANCIAL CORPORATION AND SUBSIDIARIES
(a majority-owned subsidiary of State Automobile Mutual Insurance Company)

Notes to Consolidated Financial Statements, Continued

the Company’s Equity Incentive Compensation Plan and Outside Directors Restricted Share Unit Plan approved
by shareholders in 2005). However, had the Company adopted SFAS 123(R) in prior periods, the impact of that
standard would have approximated the impact of SFAS 123 as described in the disclosure of pro forma net
income and earnings per share in Note 1k. SFAS 123(R) also requires that the benefits of tax deductions in
excess of recognized compensation cost be reported as a financing cash flow, rather than as an operating cash
flow as required under current literature. This requirement will reduce net operating cash flows and increase net
financing cash flows in periods after adoption. While the Company cannot estimate what those amounts will be
in the future (because they depend on, among other things, when employees exercise stock options), the amount
of operating cash flows recognized in prior periods for such excess tax deductions were $1.8 million, $2.3
million and $2.1 million in 2005, 2004 and 2003, respectively.

Currently, under SFAS 123 for pro-forma disclosure, the Company uses the Black-Scholes-Merton formula
to estimate the value of stock options granted to employees and will continue to use this acceptable option
valuation model upon the required adoption of SFAS 123(R) on January 1, 2006. Under SFAS 123, the Company
recognized compensation cost over the explicit service vesting period and will continue to do so for share-based
awards granted prior to the adoption of SFAS 123(R). Upon adoption of SFAS 123(R), the compensation cost
attributable to an award granted to an employee who becomes eligible to retire prior to the end of the vesting
period will be recognized over the period until the earliest date of eligible retirement. Had compensation expense
been accelerated due to retirement eligibility, pro-forma stock compensation expense, net of tax would have been
$4.2 million, $2.9 million and $2.3 million in 2005, 2004 and 2003, respectively.

2. Investments

During 2005, the Company recognized realized losses on other-than-temporary impairments of $0.6 million
on its fixed maturity portfolio and $1.0 million on its equity security portfolio, and in 2004, $0.2 million on its
fixed maturity portfolio. The Company reviewed its investments at December 31, 2005, and determined no
additional other-than-temporary impairment exists in the gross unrealized holding losses, as provided in the table
below, due to the evidence that exists indicating temporary impairment.

Realized and unrealized gains and losses for the year ended December 31, are summarized as follows:

See Note 1d for assessment of other-than-temporary impairments. The Company believes the above fixed
maturity and equity securities unrealized losses are temporary as the Company has the positive ability and intent
to hold the investments for a period of time sufficient for an anticipated market price recovery up to or beyond
the cost of the investment or maturity. Also, for declines in value that are not solely attributable to interest rate
movements, the Company considers positive evidence indicating that the cost of the investment is recoverable

Expected maturities may differ from contractual maturities because the issuers may have the right to call or

prepay the obligations with or without call or prepayment penalties.

Fixed maturities with fair values of approximately $52.5 million and $52.3 million were on deposit with

regulators as required by law or specific escrow agreement at December 31, 2005 and 2004, respectively.

The Company participates in a securities lending program whereby certain fixed maturity and equity
securities from the Company’s investment portfolio are loaned to other institutions for short periods of time. The
Company requires collateral, equal to 102% of the market value of the loaned securities. Market values are
determined as defined in Note 3 pertaining to investment securities. The collateral is invested by the lending
agent, in accordance with Company’s guidelines, generating investment income, net of applicable fees. The
Company accounts for this program as a secured borrowing and records the collateral held and corresponding
liability to return the collateral on its balance sheet. At December 31, 2005 and 2004, the amount of collateral
held was approximately, $99.0 million and $144.7 million, respectively, and the market value of securities lent
was approximately $96.0 million and $140.4 million, respectively.

The Company’s current investment strategy does not rely on the use of derivative financial instruments. See

Note 3 for additional fair value disclosures.

3. Fair Value of Financial Instruments

The following methods and assumptions were used by the Company in estimating its fair value disclosures

for financial instruments:

Investment securities: Fair values for investments in fixed maturities are based on quoted market prices,
where available. For fixed maturities not actively traded, fair values are estimated using values obtained
from independent pricing services. The fair values for equity securities are based on quoted market prices.

Cash and cash equivalents: The carrying amounts reported in the balance sheets for these instruments
approximate their fair value, because of their short-term nature.

Notes payable and interest swap: The Mutual note and Trust Preferred note (each as defined below)
carrying amounts reported in the consolidated balance sheets for these instruments approximate their fair
value as the interest rates adjust annually and quarterly, respectively. The $100.0 million, 6.25% Senior
Notes (defined below) have a fair value of $101.3 million and $108.0 million at December 31, 2005 and
2004, respectively. The fair value of the Senior Notes is based on the quoted market price at December 31,
2005 and 2004.

The Company recorded favorable loss reserve development in 2005, 2004 and 2003 of $44.3 million, $22.2
million and $1.8 million, respectively. Normal fluctuations and uncertainty associated with loss reserve
development and claim settlement contributed to the favorable development in the respective calendar years.
Impacting the 2005 development was favorable development of $5.8 million on 2004 and prior catastrophe
losses, approximately $14.4 million of changes in ceded claim reserves along with lower cost projections for
unallocated loss adjustment expense reserves.

5. Reinsurance

In the ordinary course of business, the Company assumes and cedes reinsurance with other insurers and
reinsurers and is a member in various pools and associations. See Note 6a for discussion of reinsurance with
affiliates. The voluntary arrangements provide greater diversification of business and limit the maximum net loss
potential arising from large risks and catastrophes. Most of the ceded reinsurance is effected under reinsurance
contracts known as treaties; the remainder is by negotiation on individual risks. Although the ceding of
reinsurance does not discharge the original insurer from its primary liability to its policyholder, the insurance
company that assumes the coverage assumes the related liability.

Amounts recoverable from reinsurers are estimated in a manner consistent with the claim liability associated
with the reinsured business. The recoverability of these assets depends on the reinsurers’ ability to perform under
the reinsurance agreements. The Company evaluates and monitors the financial condition and concentrations of
credit risk associated with its reinsurers under voluntary reinsurance arrangements to minimize its exposure to
significant losses from reinsurer insolvencies. The Company has reported ceded losses and loss expenses payable
and prepaid reinsurance premiums with other insurers and reinsurers as assets. All reinsurance contracts provide
for indemnification against loss or liability relating to insurance risk and have been accounted for as reinsurance.

Prior to the reinsurance transaction with Mutual under the Pooling Arrangement, as discussed in Note 6a,
the effect of the Company’s external reinsurance on its balance sheets and income statements, are summarized as

a. Reinsurance

Prior to 2005, State Auto P&C, Milbank, Farmers, SA Ohio (the “STFC Pooled Companies”), State Auto
Insurance Company of Wisconsin (“SA Wisconsin”) and State Auto Florida Insurance Company (“SA Florida”)
participated in a quota share reinsurance pooling arrangement (the “Pooling Arrangement”) with Mutual.
Effective January 1, 2005, the Pooling Arrangement was amended to add as participants Meridian Security
Insurance Company (“Meridian Security”) and Meridian Citizens Mutual Insurance Company (“Meridian
Citizens”), Indiana domiciled property and casualty insurers (collectively, the “Meridian Insurers”). Meridian
Security is a wholly-owned subsidiary of Meridian Insurance Group, Inc. (“MIGI”), which is wholly-owned by
Mutual. MIGI is party to an affiliation agreement with Meridian Citizens. SA Wisconsin and SA Florida are
wholly owned subsidiaries of Mutual.

In conjunction with the Pooling Arrangement amendment, the STFC Pooled Companies received $54.0
million in cash from the Meridian Insurers which related to the additional net insurance liabilities assumed on
January 1, 2005. The following table presents the impact on the Company’s balance sheet relating to the
additional net insurance liabilities assumed on this date:

Notes to Consolidated Financial Statements, Continued

Under the Pooling Arrangement, the STFC Pooled Companies, SA Wisconsin, SA Florida and the Meridian
Insurers cede to Mutual all of their insurance business and assume from Mutual an amount equal to their
respective participation percentages in the Pooling Arrangement. The STFC Pooled Companies’ pooling
participation percentage remained at 80% under the amended pooling arrangement effective January 1, 2005. All
premiums, losses and loss expenses and underwriting expenses are allocated among the participants on the basis
of each Company’s participation percentage in the Pooling Arrangement. The Pooling Arrangement provides
indemnification against loss or liability relating to insurance risk and has been accounted for as reinsurance.

The Pooling Arrangement does not relieve each individual pooled subsidiary of its primary liability as the
originating insurer; consequently, there is a concentration of credit risk arising from business ceded to Mutual.
As the Pooling Arrangement provides for the right of offset, the Company has reported losses and loss expenses
payable and prepaid reinsurance premiums to Mutual as assets only in situations when net amounts ceded to
Mutual exceed that assumed. The STFC Pooled Companies’ participation percentage was 80% for the years
2005, 2004 and 2003. All parties that participate in the Pooling Arrangement have an A.M. Best rating of A+
(Superior).

The following provides a summary of the reinsurance transactions on the Company’s balance sheets and

income statements for the Pooling Arrangement between the STFC Pooled Companies and Mutual:

agreement, the Company has assumed from Mutual and its affiliates premiums written and earned of $2.7
million, $2.7 million and $2.8 million for 2005, 2004 and 2003, respectively. There have been no losses assumed
under this agreement. The catastrophe reinsurance program with State Auto P&C has been excluded from the
Pooling Arrangement.

The Credit Facility (defined below) replaces a credit agreement dated in November 2003, (the “Old Credit
Agreement”), among SAF Funding Corporation, a special purpose company (“SPC”), a financial institution and a
syndicate of other lenders (the “Lenders”), which expired in accordance with its terms in November 2005. The
Credit Facility provides State Auto Financial with greater flexibility than this prior arrangement. The Old Credit
Agreement and related agreements were part of a structured contingent financing arrangement which provided
State Auto Financial with up to $100.0 million of funding for reinsurance purposes if the State Auto Group were
to incur catastrophe losses in excess of $120.0 million. In the event of an applicable catastrophic loss, this
structured contingent financing arrangement provided that State Auto Financial would sell redeemable preferred
shares to SPC which would borrow the money necessary for such purchase from the Lenders. State Auto
Financial would then contribute to State Auto P&C the funds received from the sale of its preferred shares,
thereby preserving the statutory surplus of State Auto P&C. State Auto P&C would use the contributed capital to
pay its direct catastrophe losses and losses assumed under the intercompany catastrophe reinsurance agreement.
State Auto Financial was obligated to repay SPC (which would repay the Lenders) by redeeming the preferred
shares in ten semiannual installments. In the event of a default by State Auto Financial, the obligation to repay
SPC was secured by a Put Agreement among State Auto Financial, Mutual and the Lenders, under which Mutual
would be obligated to either purchase the preferred shares from SPC or repay SPC for the loan(s) outstanding.

For the period October 1, 2001 through December 31, 2003, Mutual entered into a stop loss reinsurance
arrangement (“Stop Loss”) with the STFC Pooled Companies. Under the Stop Loss, Mutual agreed to participate
in the Pooling Arrangement’s quarterly underwriting losses and gains in the manner described. If the Pooling
Arrangement’s statutory loss and loss adjustment expense ratio (loss ratio) was between 70.75% and 80% (after
the application of all available reinsurance), Mutual reinsured the STFC Pooled Companies 27% of the Pooling
Arrangement’s losses in excess of a loss ratio of 70.75% up to 80.00%. The STFC Pooled Companies were
responsible for their share of the Pooling Arrangement’s losses over the 80% threshold. Also, Mutual had the
right
the Pooling
Arrangement’s underwriting profits attributable to loss ratios less than 69.25%, but more than 59.99%. During
2003, the STFC Pooled Companies ceded to Mutual, $5.6 million in losses and $12.8 million in premiums under
the Stop Loss. The Stop Loss ceased at December 31, 2003.

As of July 1, 2005, SA National and Mutual terminated a reinsurance agreement between the parties that
included excess of loss and quota share coverages. SA National and Mutual mutually agreed to terminate the
reinsurance agreement because of SA National’s stronger surplus position, relative to the commencement date of
the agreement, which makes it more efficient for SA National to retain such exposures rather than to reinsure
them. Under the terms of the termination, Mutual will continue to be liable, with respect to policies in force at the
termination date, for occurrences until the expiration, cancellation or next anniversary, not to exceed one year.

b. Intercompany Balances

Pursuant to the Pooling Arrangement, Mutual receives all premiums and pays all losses and expenses
associated with the insurance business produced by the pool participants and then settles the intercompany
balances generated by these transactions with the participating companies on a quarterly basis within 45 days
following each quarter end. No interest is paid on this balance. When settling the intercompany balances, Mutual
provides the pool participants with full credit for the premiums written and net losses paid during the quarter and
retains all receivable amounts from insureds and agents and reinsurance recoverable on paid losses from
unaffiliated reinsurers. Any receivable amounts that are ultimately deemed to be uncollectible are charged-off by
Mutual and allocated to the pool member on the basis of pool participation. As a result, the Company has an
off-balance sheet credit–risk related to the balances due to Mutual from insureds, agents and reinsurers, which is
offset by the unearned premium from the respective policies. The Company’s share of the premium balances due
to Mutual from agents and insureds at December 31, 2005 and 2004 is approximately $255.1 million and $214.2
million, respectively.

c. Notes Payable

In 1999, State Auto Financial entered into a line of credit agreement with Mutual for $45.5 million in
conjunction with its stock repurchase program. Principal payment was due on demand, but not later than
December 31, 2005. The interest rate was adjustable annually at January 1 to reflect adjustments in the then
current prime lending rate less 1.75% as well as State Auto Financial’s current financial position and for the
years 2005, 2004 and 2003 was 3.50%, 2.25% and 2.50%, respectively. On December 27, 2005, State Auto
Financial repaid its $45.5 million outstanding line of credit with Mutual.

On May 22, 2003, STFC Capital Trust I, State Auto Financial’s Delaware business trust subsidiary (the
“Capital Trust”), issued $15.0 million liquidation amount of its capital securities to a third party. In connection
with the Capital Trust’s issuance of the capital securities and the related purchase by State Auto Financial of all
of the Capital Trust’s common securities (liquidation amount of $0.5 million included in other invested assets),
State Auto Financial issued to the Capital Trust $15.5 million aggregate principal amount of Floating Rate Junior
Subordinated Debt Securities due 2033 (the “Subordinated Debentures”). The sole assets of the Capital Trust are
the Subordinated Debentures and any interest accrued thereon. Interest on the Capital Trust’s capital and

Notes to Consolidated Financial Statements, Continued

common securities (the “Trust Securities”) is payable quarterly at a rate equal to the three-month LIBOR rate
plus 4.20%, adjusted quarterly (total 8.61% at December 31, 2005). Prior to May 2008, the interest rate may not
exceed 12.5% per annum. The interest rate and interest payment dates on the Subordinated Debentures are the
same as the interest rate and interest payment dates on the Trust Securities. In January 2003, the FASB issued
FIN 46, Consolidation of Variable Interest Entities, effective for reporting periods beginning after June 15, 2003.
As a result of the Company’s adopting FIN 46 effective July 1, 2003, the financial statements of the Capital Trust
are not consolidated within the accompanying financial statements of the Company.

The Trust Securities are mandatorily redeemable on May 23, 2033, and may be redeemed at any time on and
after May 23, 2008, at 100% of the principal amount thereof plus unpaid interest. The Trust Securities may be
redeemed in whole, but not in part, at any time within 90 days following the occurrence of a “Tax Event” or
“Investment Company Event” (as defined in the declaration of trust) (a) if such Tax Event or Investment
Company Event occurs on or after May 23, 2008, at a redemption price equal to 100% of the principal amount
thereof plus unpaid interest, and (b) if such Tax Event or Investment Company Event occurs prior to May 23,
2008, at a redemption price equal to the greater of 100% of the principal amount thereof plus accrued interest and
a “make-whole” amount. The Subordinated Debentures are subject to these same redemption terms. The
obligations under the Subordinated Debentures and related agreements, taken together, constitute a full and
unconditional guarantee of payments due on the Trust Securities. No deferments have been made under the plan.

State Auto Financial has the right, at any time, to defer payments of interest on the Subordinated Debentures
for up to 20 consecutive quarterly payment periods. Consequently, distributions on the Trust Securities would be
deferred (though such distributions would continue to accrue with interest since interest would accrue on the
Subordinated Debentures during any such extended interest payment period). In no case may the deferral of
payments and distributions extend beyond the stated maturity dates of the respective securities. During such
deferments, State Auto Financial may not declare or pay any dividends on, or purchase any of, its capital stock,
make any principal or interest payments on debt securities that rank in all respects equally with or subordinated
to the Subordinated Debentures, or make any payment under guarantees that rank in all respects equally with or
subordinated to State Auto Financial’s guaranty of the Trust Securities.

The Subordinated Debentures are unsecured and subordinated to all of the Company’s existing and future
senior indebtedness. As sponsor of the Capital Trust, State Auto Financial incurred security issuance costs related
to the Trust Preferred Capital Securities and Subordinated Debentures of $0.5 million, which is recorded in other
assets and is being amortized into interest expense ($18,000 for 2005 and 2004) as the underlying interest
expense is recognized on the Trust Securities.

d. Management Services

Stateco provides Mutual and its affiliates investment management services. Investment management income
is recognized quarterly based on a percentage of the average fair value of investable assets and the equity
portfolio performance of each company managed. Revenue related to these services amounted to $2.3 million,
$2.5 million and $2.2 million in 2005, 2004 and 2003, respectively, and is included in other income (affiliates).

State Auto P&C provides management and operation services to certain of Mutual’s insurance affiliates for
a fee. Revenue relating to these services amounted to $0.3 million, $1.0 million and $1.1 million in 2005, 2004
and 2003, respectively, and is included in other income (affiliates).

STATE AUTO FINANCIAL CORPORATION AND SUBSIDIARIES

December 31, 1990 liability, if any, is to be reimbursed by Mutual to State Auto P&C in conformance with
pooling percentages in place at that time. As of December 31, 2005, there has been no adverse development of
the liability.

7. Notes Payable and Derivatives

In November 2003, State Auto Financial issued $100.0 million unsecured senior notes (“Senior Notes”)
bearing interest fixed at 6.25% due November 15, 2013. Interest on the Senior Notes is payable May 15 and
November 15 of each year beginning May 15, 2004. The Senior Notes are general unsecured obligations ranking
senior to all existing and future subordinated indebtedness and equal with all existing and future senior
indebtedness. The Senior Notes are not guaranteed by any of the Company subsidiaries and thereby are
effectively subordinated to all Company subsidiaries’ existing and future indebtedness. State Auto Financial may
redeem the Senior Notes in whole at any time or in part from time to time at State Auto Financial’s option, on at
least 30 but not more than 60 days’ prior written notice, at a redemption price equal to the greater of the principal
amount of such notes being redeemed on the redemption date or the make whole amount, based on U.S. Treasury
rates as defined by the Senior Notes, plus in each case, accrued and unpaid interest, if any, on the Senior Notes to
the redemption date. The Senior Notes issued contain certain covenants as defined in the notes, which among
other things, limit State Auto Financial and its subsidiaries ability to issue indebtedness secured by the capital
stock of certain State Auto Financial subsidiaries and sell the capital stock of certain State Auto Financial
subsidiaries. The Senior Notes also contain a covenant that requires State Auto Financial to take certain actions
in the event it engages in mergers, consolidations or sales of all or substantially all of the assets and prohibits
State Auto Financial from engaging in such transaction if the Company is in default under the Senior Notes. State
Auto Financial incurred $1.5 million in issuance costs related to the Senior Notes, which is recorded in other
assets and is being amortized into interest expense ($0.1 million for 2005 and 2004) as the underlying interest
expense is recognized on the Trust Securities.

In October 2003, State Auto Financial entered into an interest rate swap contract for a notional amount of
$25.0 million as a hedge on the ten year treasury rate in connection with the forecasted issuance of the Senior
Notes. The swap contract was designated as a cash flow hedge and settled in November 2003, the pricing date of
the Senior Notes, with the Company receiving $0.8 million. The gain has been recorded in accumulated other
comprehensive income and is being amortized as an offset to interest expense ($0.1 million for 2005 and 2004)
as the underlying interest expense is recognized for the Senior Notes.

In November 2003, State Auto Financial entered into an interest rate swap contract for a notional amount of
$50.0 million receiving semiannual payments at a fixed rate of 6.25% and making semiannual payments at a
variable rate equal to six month LIBOR plus 1.25 percent with LIBOR to be determined the last day of each
interest reset period (total 2.47% at December 31, 2003). The swap contract was designated as a fair value hedge
to protect against changes in fair value of the Senior Notes. Recorded in other assets at December 31, 2003, the
fair market value of the fixed to floating interest rate swap was $0.5 million of which $0.2 million related to net
accrued interest to be received and reduce reported interest expense in the period. During March 2004, State Auto
Financial terminated its interest rate swap contract entered into in November 2003 and received proceeds of $2.9
million. Of the $2.9 million received, $2.3 million settled future net swap payments and was deferred in notes
payable and will be amortized as an offset to interest expense over the life of the Senior Notes. The remaining
$0.6 million related to net swap payments from inception to termination and was recorded as an offset to interest
expense.

In May 2004, State Auto Financial entered into an interest rate swap contract for a notional amount of $50.0
million, receiving semiannual payments at a fixed rate of 6.25% and making semiannual payments at a variable

87

(a majority-owned subsidiary of State Automobile Mutual Insurance Company)

Notes to Consolidated Financial Statements, Continued

rate equal to the six month LIBOR plus 0.94% with LIBOR to be determined the last day of each interest reset
period. The swap contract was designated as a fair value hedge to protect against changes in fair value of the
Senior Notes. During August 2004, State Auto Financial terminated the interest rate swap contract entered into in
May 2004 and received proceeds of $1.8 million. Of the $1.8 million received, $1.5 million settled future net
swap payments and was deferred in notes payable and will be amortized as an offset to interest expense over the
life of the Senior Notes. The remaining $0.3 million related to net swap payments from inception to termination
and was recorded as an offset to interest expense. The amount of hedge ineffectiveness, in all periods presented,
was not material.

In November 2005, State Auto Financial entered into a Credit Agreement (the “Credit Agreement”) with a
financial institution and a syndicate of other lenders to provide for a $100.0 million five-year unsecured
revolving credit facility (the “Credit Facility”). During the term of the Credit Facility, State Auto Financial has
the right to increase the total facility amount by $25.0 million, up to a maximum total facility amount of
$125.0 million, provided that no event of default has occurred and is continuing. The Credit Facility is available
for general corporate purposes, including working capital and acquisitions, and for catastrophic loss purposes. At
the present time, the Company intends to use the Credit Facility for catastrophe loss purposes. The Credit Facility
provides for interest-only payments during its term, with principal due in full at maturity. Interest is based on
either a London interbank market rate or a base rate plus a calculated margin amount. In addition to paying a
quarterly fee to have these funds available, the Credit Agreement contains certain covenants, including financial
covenants that require State Auto Financial to (i) maintain a minimum net worth, (ii) not exceed a certain debt to
capitalization ratio and (iii) not go below a certain fixed charge coverage ratio. As of December 31, 2005, State
Auto Financial had no borrowings under the Credit Agreement and was in compliance with all its covenants.

The Company is required to establish a valuation allowance for any portion of the deferred tax asset that
management believes will not be realized. In the opinion of management, it is more likely than not that the
Company will realize the benefit of the deferred tax assets and, therefore, no such valuation allowance has been
established.

9. Pension and Postretirement Benefit Plans

The Company provides a defined benefit plan for its eligible employees. Substantially all Company
employees become eligible to participate the year after becoming 20 years of age and vest with 5 years of
credited service or attained age 65. The Company’s policy is to fund pension costs in accordance with the
requirements of the Employee Retirement Income Security Act of 1974. Benefits are determined by applying
factors specified in the plan to a participant’s defined average annual compensation.

In addition to the pension benefit plan, the Company provides a postretirement benefit plan including certain
health care and life insurance benefits for its eligible retired employees. Substantially all of the Company’s

89

STATE AUTO FINANCIAL CORPORATION AND SUBSIDIARIES
(a majority-owned subsidiary of State Automobile Mutual Insurance Company)

Notes to Consolidated Financial Statements, Continued

employees may become eligible for these postretirement benefits if they retire between age 55 and 65 with 15
years or more of service or if they retire at age 65 or later with 5 years or more of service.

On December 8, 2003, the Medicare Prescription Drug, Improvement and Modernization Act of 2003 (the
“Act”) was signed into law. The Act expanded Medicare to include, for the first time, coverage for prescription
drugs. In May of 2004, the FASB issued FASB Staff Position 106-2, “Accounting and Disclosure Requirements
Related to the Medicare Prescription Drug, Improvement and Modernization Act of 2003” (“FSP 106-2”). FSP
106-2 provided guidance on accounting for the effects of the Act for employers that sponsor postretirement
health care plans that provide drug benefits. The Company and its actuarial advisors completed a review of its
plan provisions and concluded that the benefits provided by its plan are actuarially equivalent to Medicare Part D
and will be entitled to the subsidy. The Company determined that the enactment of the Act was not a significant
event and incorporated the effect of the Act in the most recent measurement date pursuant to FSP 106-2.

The Company used September 30, 2005 and 2004, to determine the pension and postretirement benefit
measurements. The accumulated benefit obligation with respect to the pension benefit plan was $171.8 million
and $148.3 million as of December 31, 2005 and 2004, respectively.

The Company’s defined benefit plan obligations are long-term in nature and consequently the investment
strategies have a long-term time horizon. In establishing the long term rate of return assumption on plan assets,
management, along with its pension consulting actuary, reviews the historical performance of the plan assets and
the stability in mix of investment portfolio. The expected inflation rate and expected real rates of return of
applicable asset classes are then determined to assist in setting appropriate assumptions. The relatively stable
investment strategy between fixed maturities and equity securities has produced a 10 year average rate of return
on plan assets through September 30, 2005 of 9.51%.

The plan’s investment policy objective is to preserve the investment principal while generating income and
appreciation in fair value to meet the plans’ obligations. The plans’ investment strategy and risk tolerance is
balanced between meeting cash obligation requirements and a long term relatively high risk tolerance. Since the
nature and timing of the plans’ liabilities and cash requirements are predictable, the liquidity requirements are
somewhat moderate. Therefore, the Trustees of the plan have authorized that at least 75% of the plans’ assets
should be in public marketable securities. Bond investments will normally range from 10 to 20 years in maturity.
Debt instruments, convertible debt and preferred stock are rated “A” or better by two major rating services. The
equity portfolio is comprised primarily of large capitalization, high quality stocks with a strong earnings growth
and dividends payment history. Total holding of a specific stock cannot exceed 2% of the outstanding stock. No
one equity holding can be greater than 5% of the total equity portfolio. Total holdings of bonds and stocks of any
one corporation cannot exceed 5% of assets.

The actuarially prepared funding amount to the pension plan ranges from the minimum amount the
Company would be required to contribute to the maximum amount that would be deductible for tax purposes.
Contributed amounts in excess of the minimum amounts are deemed voluntary. Amounts in excess of the
maximum amount would be subject to an excise tax and may not be deductible for tax purposes. This range is
generally not determined until the second quarter with respect to the contribution year. The Company expects to
contribute approximately $10.0 million during 2006 to its pension plan, depending on the actuarially calculated
funding requirements of such plan. Postretirement and SERP plan payments are deductible for tax purposes when
paid.

The following benefit payments, which reflect expected future service, as appropriate, are expected to be

paid:

at December 31, 2005 and 2004 was $4.3 million and $4.1 million, respectively, that is included in the balance
sheet postretirement benefit liabilities amount.

The Company maintains a defined contribution plan that covers substantially all employees of the Company.
The Company matches the first 2% of contributions of participants’ salary at the rate of 75 cents for each dollar
contributed. Participant contributions of 3% to 6% are matched at a rate of 50 cents for each dollar contributed.
The Company’s share of the expense under the plan totaled $2.4 million, $2.2 million and $2.1 million for the
years 2005, 2004 and 2003, respectively.

10. Stockholders’ Equity

a. Treasury Shares

On March 1, 2002, the State Auto Financial’s Board of Directors approved a plan to repurchase up to
1.0 million shares of common stock from the public over a period extending to and through December 31, 2003.
Through December 31, 2003, State Auto Financial repurchased 0.5 million shares from the public under this plan
of which 0.1 million was purchased during 2003. Repurchases during 2003 were funded through dividends from
subsidiaries.

b. Dividend Restrictions and Statutory Financial Information

State Auto P&C, Milbank, Farmers, SA Ohio and SA National are subject to regulations and restrictions
under which payment of dividends from statutory earned surplus can be made to State Auto Financial during the
year without prior approval of regulatory authorities. Pursuant to these rules, approximately $121.2 million, less
any dividend payments in the preceding twelve month period, is available for payment to State Auto Financial in
2006 without prior approval. State Auto Financial received dividends of $40.5 million and $12.0 million from its
insurance subsidiaries in 2005 and 2004, respectively.

Reconciliations of statutory capital and surplus and net income (loss), as determined using statutory

11. Preferred Stock

State Auto Financial has authorized two classes of preferred stock. For both classes, upon issuance, the
Board of Directors has authority to fix and determine the significant features of the shares issued, including,
among other things, the dividend rate, redemption price, redemption rights, conversion features and liquidation
price payable in the event of any liquidation, dissolution, or winding up of the affairs of State Auto Financial.

The Class A preferred stock is not entitled to voting rights until, for any period, dividends are in arrears in

the amount of six or more quarterly dividends.

12. Stock Incentive Plans

The Company maintains stock-based compensation plans for

its key employees and outside, or
non-employee, directors. The stock-based compensation plan for key employees is the Amended and Restated
Equity Incentive Compensation Plan (the “Equity Plan”). In May 2005, the Company’s shareholders approved
amendments to, and a restatement of, the Equity Plan, which was formerly called the 2000 Stock Option Plan.
The stock-based compensation plan for outside directors is the Outside Directors Restricted Share Unit Plan (the
“Outside Directors RSU Plan”), which was approved by the Company’s shareholders in May 2005. The Outside
Directors RSU Plan replaced the 2000 Directors Stock Option Plan for outside directors (the “Outside Directors
Stock Option Plan”).

The 2000 Stock Option Plan provided only for the award of qualified and nonqualified stock options. The
Equity Plan now provides for the award of qualified and nonqualified stock options, restricted shares,
performance shares, performance units and other stock-based awards. The Company has reserved 3.5 million
common shares under the Equity Plan (5.0 million common shares under the 2000 Stock Option Plan). As of
December 31, 2005, a total of 1,821,211 common shares were available for issuance under the Equity Plan. The
Equity Plan provides that (i) no more than 33% of the common shares authorized for issuance under the Equity
Plan may be granted in the form of awards other than stock options, (ii) the maximum number of common shares
subject to awards of stock options, restricted shares and performance shares that may be granted in any calendar
year is equal to 1.5% of the total number of common shares of the Company outstanding as of December 31 of
the prior year, and (iii) the maximum number of common shares subject to awards of stock options, restricted
shares and performance shares that may be granted in any calendar year to any individual is 250,000 shares. The
Equity Plan automatically terminates on July 1, 2010.

STATE AUTO FINANCIAL CORPORATION AND SUBSIDIARIES
(a majority-owned subsidiary of State Automobile Mutual Insurance Company)

Notes to Consolidated Financial Statements, Continued

During both 2005 and 2004, options to purchase 0.4 million common shares were granted to key employees
under the Equity Plan. The Equity Plan provides that qualified stock options may be granted at an option price
not less than the fair market value of the common shares at date of grant and that nonqualified stock options may
be granted at any price determined by the Compensation Committee of the Board of Directors. Options granted
in 2005 and 2004 generally vest over a three-year period, with one-third of the options vesting on each
anniversary of the grant date, and must be exercised no later than ten years from the date of grant.

The Company also has a broad-based employee stock purchase plan with a dividend reinvestment feature,
under which employees of the Company may choose at two different specified time intervals each year to have
up to 6% of their annual base earnings withheld to purchase the Company’s common shares. The purchase price
of the common shares is 85% of the lower of its beginning-of-interval or end-of-interval market price. The
Company has reserved 2.4 million common shares under this plan. As of December 31, 2005, a total of
2.2 million common shares have been purchased under this plan.

Under the Outside Directors Stock Option Plan, following each annual meeting of shareholders outside
directors received non-qualified options to purchase 4,200 common shares at an option price equal to the fair
market value of the common shares at the close of business on the last trading day immediately prior to the date
of the annual meeting. These non-qualified options vested upon grant and are exercisable for 10 years from the
date of grant. On May 11, 2005 (the date of the Company’s 2005 annual meeting of shareholders), the Outside
Directors Stock Option Plan was amended to prohibit the grant of further options under the plan.

The Outside Directors RSU Plan is an unfunded deferred compensation plan which provides each outside
director with an award of 1,400 restricted share units (the “RSU award”) following each annual meeting of
shareholders. In 2005, a total of 9,800 RSU awards were made to outside directors. The RSU awards are fully
vested upon grant. RSU awards are not common shares of the Company and, as such, no participant has any
rights as a holder of common shares under the Outside Directors RSU Plan. RSU awards represent the right to
receive an amount, payable in cash or common shares of the Company, as previously elected by the outside
director, equal to the value of a specified number of common shares of the Company at the end of the restricted
period. The restricted period for the RSU awards begins on the date of grant and expires on the date the outside
director retires from or otherwise terminates service as a director of the Company. During the restricted period,
outside directors are credited with dividends, equivalent in value to those declared and paid on the Company’s
common shares, on all RSU awards granted to them. At the end of the restricted period, outside directors receive
distributions of their RSU awards either (i) in a single lump sum payment, or (ii) in annual installment payments
over a five- or ten-year period, as previously elected by the outside director. The administrative committee for
the Outside Directors RSU Plan (currently the Company’s Compensation Committee) retains the right to increase
the annual number of RSU awards granted to each outside director to as many as 5,000 or to decrease such
annual number to not less than 500, without seeking shareholder approval, if such increase or decrease is deemed
appropriate by the administrative committee to maintain director compensation at appropriate levels. The Outside
Directors RSU Plan automatically terminates on May 31, 2015.

The Company uses the intrinsic value based method of accounting for the RSUs, under which accumulated
compensation cost is equal to 100% of the total number of the RSUs awarded, plus any dividend equivalents,
multiplied by the quoted market price of the Company stock at each reporting date. The amount of the award is
recognized as compensation cost upon grant as vesting is immediate. Compensation cost charged to expense with
respect to RSUs was $0.4 million for 2005.

The Company has a stock option incentive plan for certain designated independent insurance agencies that
represent the Company and its affiliates. The Company has reserved 0.4 million shares of common stock under

this plan. The plan provides that the options become exercisable on the first day of the calendar year following
the agency’s achievement of specific production and profitability requirements over a period not greater than two
calendar years from the date of grant or a portion thereof in the first calendar year in which an agency
commences participation under the plan. Options granted under this plan have a ten year term. The Company has
accounted for this plan in its accompanying financial statements at fair value. Expenses associated with this plan
of $0.3 million, $0.2 million and $0.3 million were recognized in 2005, 2004 and 2003, respectively.

The fair value of the agent options granted was estimated at the reporting date or vesting date using the
Black-Scholes-Merton option-pricing model. The weighted average fair value and related assumptions are as

15. Reportable Segments

At December 31, 2005, the Company has three reportable segments: standard insurance, nonstandard
insurance, and investment management services. The reportable segments are business units managed separately
because of the differences in products or service they offer, type of customer they serve or because of
management considerations. The standard and nonstandard segments operate primarily in the central and eastern
United States, excluding New York, New Jersey, and the New England states, distributing products through the
independent insurance agency system.

The standard insurance segment provides personal and commercial insurance to its policyholders. Its
principal lines of business include personal and commercial automobile, homeowners, commercial multi-peril,
workers’ compensation, general
liability and fire insurance. The nonstandard insurance segment provides
personal automobile insurance to policyholders that are typically rejected or canceled by standard insurance
carriers because of various reasons deemed relevant to such carriers.

The investment management services segment manages the investment portfolios of affiliated insurance
companies. Beginning January 1, 2006, this segment will no longer be reported as a separate segment as its
results no longer meet the quantitative thresholds for separate presentation as a reportable segment, even with
consideration of aggregation of other segments with similar economic characteristics, among other factors.

The Company evaluates performance of its reportable segments and allocates resources thereon based on
profit or loss from operations, excluding net realized gains on investments on the Company’s investment
portfolio, before federal income taxes. The accounting policies of the reportable segments are the same as those
described in the summary of significant accounting policies.

Revenue from segments in the other category is attributable to three other operating segments of the
Company, which individually are not material: management and operations services segment, an insurance
software development and resale segment, and a property management and leasing segment.

litigation arising in the ordinary course of business. Additionally, the insurance subsidiaries may be impacted by

Item 9A. Controls and Procedures

Management’s Annual Report on Internal Control Over Financial Reporting

Management’s annual report on internal control over financial reporting required by Item 308(a) of
Regulation S-K follows. The attestation report of the independent registered public accounting firm required by
Item 308(b) of Regulation S-K is found under the caption “Report of the Independent Registered Public
Accounting Firm” in Item 8 of this Form 10-K.

The following report is provided by the Company’s management on the Company’s internal control over

financial reporting (as defined in Rule 13a-15(f) of the Exchange Act):

1.

2.

The Company’s management is responsible for establishing and maintaining adequate internal control
over financial reporting for the Company.

The Company’s management has used the Committee Of Sponsoring Organizations of the Treadway
Commission (COSO) framework to evaluate the effectiveness of the Company’s internal control over
financial reporting. Management believes that the COSO framework is a suitable framework for its
evaluation of the Company’s internal control over financial reporting because it is free from bias,
permits reasonably qualitative and quantitative measurements of the Company’s internal controls, is
sufficiently complete so that those relevant factors that would alter a conclusion about the effectiveness
of the Company’s internal controls are not omitted and is relevant to an evaluation of internal control
over financial reporting.

3. Management has assessed the effectiveness of the Company’s internal control over financial reporting
as of December 31, 2005, and has concluded that such internal control over financial reporting is
effective. There are no material weaknesses in the Company’s internal control over financial reporting
that have been identified by management.

Our management’s assessment of the effectiveness of the Company’s internal control over financial
reporting as of December 31, 2005, has been audited by Ernst & Young LLP, an independent registered public
accounting firm, as stated in their report which is included herein.

Disclosure Controls and Procedures

The Company carried out an evaluation, under the supervision and with the participation of the Company’s
management, including the Company’s Chief Executive Officer and Chief Financial Officer, of the effectiveness
of the design and operation of the Company’s disclosure controls and procedures (as defined in Exchange Act
Rule 13a-15(e)). Based upon that evaluation, the Company’s Chief Executive Officer and Chief Financial Officer
concluded that, as of the end of the period covered by this report, the Company’s disclosure controls and
procedures were effective in timely alerting them to material information relating to the Company (including its
consolidated subsidiaries) required to be included in the Company’s periodic filings with the Securities and
Exchange Commission.

Changes in Internal Control over Financial Reporting

There has been no change in the Company’s internal control over financial reporting that occurred during
the Company’s most recent fiscal quarter that has materially affected, or is reasonably likely to materially affect,
the Company’s internal control over financial reporting.

Item 9B. Other information

None.
