Letter to our shareholders

2006 was a tremendous learning opportunity for me as
State Auto Financialʼs new CEO.  During this past year I
spent most of my time on the road visiting with all of our
key stakeholders: State Auto associates, agency partners,
investors and regulators.  One of the many lessons I
learned is that all of us in the property and casualty 
insurance industry are essentially telling the same story.
We all seem to have the best people, the best products,
the best service, the best agents, the best systems and,
of course, the best prospects.  Itʼs becoming increasingly
difficult to become differentiated and distinguishable in a
crowded, competitive market.  As a super regional com-
pany, we compete with large, well-entrenched national
companies for people and shelf space within agencies.
Among our agents, we compete with a variety of aggres-
sive and increasingly automated regional and specialty
companies. Among investors, we compete for capital and
attention from investors who view our industry as frag-
mented, under-performing, volatile and risky.  

What has impressed me the most about State Auto is
that we just donʼt tell a good story,  we are a good story!
While others talk about how good they are going to be, we
have been very good for a very long time.  Through hard
markets and soft markets, weʼve consistently demonstrat-
ed superior underwriting profitability, predictable earnings
and a stable outlook.  The one common denominator to all
our past successes is the quality of our people and the
strength of our culture.  Thatʼs what defines and differenti-
ates a company in our business.  And thatʼs what makes
State Auto so successful - our people.

And once again our people produced a terrific result  
in 2006 despite increasing competition and unpredictable
weather.

(cid:2) The first quarter once again demonstrated the quality of 
our underlying earnings when we reported outstanding 
performance that resulted in quarterly net income of  
$0.97 per diluted share, second best in our history.

2006 witnessed the development of Web quoting and
application submission for business insurance and the
rollout of the successful CustomFit personal auto  
product to 18 additional states. STFC, along with Vice
President-Director of Business Insurance Paul Nordman,
left, and Vice President-Director Personal Insurance Joel
Brown, is working to become the company of choice for
even more agents and insureds.

(cid:2) Things changed in the second quarter, when we experi-  

enced the worst quarterly catastrophe results weʼve 
ever had.  Significant wind and hail events in the
Midwest produced $59.8 million in claims, affecting our 
combined ratio by 23.3 points and challenging our 
claims capabilities.

(cid:2) We saw a significant improvement in the third quarter,  
when we achieved a 90.9% combined ratio, the best 
result for any third quarter in our history as a public  
company.   Unquestionably, the lack of significant  
hurricane activity helped us, but our disciplined and 
consistent underwriting and claim practices were also 
big contributors. 

(cid:2) We finished the year with an exceptionally strong  
fourth quarter: a combined ratio of 83.5% and net 
income of $1.08 per diluted share, another new record 
for a quarter.

(cid:2) For the year, we reported $120.4 million in net income 
and a fine combined ratio of 91.4%.  While organic 
growth remains a challenge, we feel we have the  
strategies and plans in place to make progress on 
that front, as well.

Building on our solid foundation, Iʼm committed to 
continuing a legacy of success and creating a culture that:
(cid:2) empowers our people with the authority necessary to  
do our jobs and the accountability that ensures we do  
them well;

(cid:2) enables our people to do their best by ensuring that we 

have the best leaders, coaches and trainers;

(cid:2) equips our people with the right kind of technology, 

tools and training programs to help us do our best; and
(cid:2) energizes our people with the kind of sales and support 
programs that will stimulate organic growth and sustain 
our tradition of overwhelming service.

Weʼve made good progress in each area over the past
year.  We have a leadership team in place that is totally
focused on building an organization that will sustain supe-
rior underwriting results, preserve our tradition of risk
management and supplement internal growth with well-
integrated acquisitions and affiliations.  

Last year, we appointed Mark Blackburn executive vice
president and chief operating officer.  Mark is responsible
for creating the infrastructure of products, services and
systems that will continue our tradition of underwriting
profitability and sustain our top line growth.  A key first
step was to build integrated product teams responsible for
personal insurance and business insurance, respectively.
This change is intended to give us a competitive and prof-
itable product portfolio and promote better alignment with-
in our field marketing organization.  We also created a
new Program Management Office (PMO) to lead the
development of all strategic projects and ensure effective

Profitability and rational growth are more than just corporate
objectives for the State Auto Group’s nine branch and 
regional offices; they’re words to work by.  Now in 28 states,
State Auto is a super regional property and casualty insurer
and its success is dependent on the sum performance of
its line operations. The regional offices report to the
directors of regional and branch operations, Vice Presidents 
Cathy Miley and Steve Hazelbaker.

Vice President-Chief Financial Officer Steve English and
Vice President-Chief Accounting Officer/Treasurer Cindy
Powell lead the financial team that is working to grow
surplus, manage capital, and maintain the company's
outstanding track record of financial strength.

Letter to our shareholders

implementation.  Lastly, Mark and his team will ensure
that we continue State Autoʼs tradition of superior risk
management, sophisticated pricing and overwhelming  
service – all critical to our continued profitability.  

Last year we also announced the first acquisition the
State Auto Group has had in a while.  Mergers, acquisi-
tions and affiliations are critical to our long-term growth
and profitability. We will be very pleased to welcome the
Beacon Insurance Group based in Wichita Falls, Texas, to
the State Auto family. We intend to acquire Beacon
through State Auto Mutual, but plan to pool the results
with State Auto Financial once weʼve successfully com-
pleted integration. Beacon will be an important addition to
the group; it allows us to broaden our spread of risk, enter
a new and large market and establish a new growth plat-
form in the West.  

Steve English was critical to the Beacon transaction and

a vital part of our capital management success over the
years.  Iʼm very pleased to have Steve as our new chief
financial officer.  Working with Cindy Powell, chief
accounting officer and treasurer, we have a terrific 
financial team in place to grow surplus, manage capital
and continue to support State Autoʼs financial strength
and success.

I am also grateful that John Lowther, our general counsel
and corporate conscience, will work with us through 2007
as we identify and transition to a new general counsel.
Over the years, Johnʼs contributions to the companyʼs  
success have not always been well publicized, but are real
and well recognized within the company.  John has been a
part of every major decision and has contributed to every
significant success State Auto has enjoyed over the last
twenty plus years.  I look forward to continuing to work
with him as we transition State Auto to the next stage of
success.

The most challenging strategic issues we have are

always related to people.  How we recruit, retain, develop,
recognize and reward quality people is what enables flaw-
less execution and sustains success.  Iʼm very pleased
that Lori Siegworth has joined our leadership team as vice
president, strategy and organizational effectiveness.
Loriʼs immediate priorities are to:

(cid:2) Conduct a review of our strategic plan with the board 

and leadership team;

(cid:2) Develop a more robust talent management capability 

and more responsive total compensation programs; and

(cid:2) Assess our sales management capability.

Under the leadership of President, Chairman and CEO
Bob Restrepo and Executive Vice President and COO
Mark Blackburn, STFC is focused on building one of the
premier super regional property and casualty insurance
companies in the nation.

Recruiting, retaining and developing high-quality people
is critical to STFC's growth. Vice President-Director of
Administration Noreen Johnson, left, and Vice President-
Director of Strategy and Organizational Effectiveness
Lorraine Siegworth are working to make the company an
even more attractive employer, while putting in place a
comprehensive strategic plan.

156652_8pg:Annual Report 2005  3/14/07  4:38 PM  Page 5

Looking forward to 2007, our strategy remains consistent.
We will need to work even harder to sharpen and acceler-
ate our execution.  Simply put, our strategy is to achieve:
(cid:2) Underwriting profitability:  it will be increasingly difficult 
to produce combined ratios in the low 90% range given 
the competition we are seeing in both personal insur- 
ance and business insurance.  Despite that, we have 
consistently demonstrated the underwriting discipline, 
risk/rate balance and claim handling capability required  
to produce consistent and superior underwriting profits.

(cid:2) Rational growth:  we remain disappointed by our below- 
average organic growth rates.  We think we now have 
the product development capability, Web-based tech- 
nology, predictive modeling plans and people necessary  
to begin to grow our business equal to or slightly better  
than industry growth rates.  2007 will be a transitional 
year in our efforts to achieve such rational growth.

(cid:2) Enterprise risk management:  we will continue to allo- 
cate capital to markets and products that can achieve 
our financial targets of a 13-15% return on equity.  In 
addition, we remain conservative in our reserving,  
investments, reinsurance purchasing and business  
continuity practices.  This is what is required to grow  
surplus and enhance book value.

(cid:2) Capital management:  we will continue to explore ways 
to leverage STFCʼs strong capital position and build  
long-term value for shareholders.  Investing in the busi- 
ness remains our first priority.  Whether it is acquisi-
tions, affiliations or start-ups, we have a proven ability 
to make prudent investments in the business that pay 
off over the long term for all our stakeholders.

Vice President-Director of Information Technology Doug
Allen, left, and Vice President-Director of Claims John
Melvin guided the transition of the company's claim  
systems to a new technology platform and improved
claim-handling service with mobile broadband 
connections for State Auto’s field claims organization.

Vice President-Director of Marketing Jean Reynolds
heads the new Program Management Office (PMO), the
company's "control tower" for project delivery.  Program
managers, seated from the left, include State Auto
Mutual AVP’s  Ben Blackmon (business insurance  
marketing), Tim Reik (personal insurance marketing),
John Heffernan (services marketing) and Lester Brue
(acquisition integration).  The PMO’s 2007 focus on
commercial lines includes package policy enhancements
and Web-based processing for agents.

Letter to our shareholders

2006 was a terrific year!  2007 will be a year of transi-
tion, as we build out the infrastructure we think is neces-
sary to maintain profitability and increase our premium
base.  We are already off to a good start.  During the past
year we have:

(cid:2) Implemented our new CustomFit personal automobile 

product in 18 states accounting for 75% of our 
personal auto premium.  New business production is 
up 37% in the states in which we have implemented 
this new product.

(cid:2) Introduced new, integrated report ordering capability 
which streamlines the handling of personal insurance 
transactions.  We now have 93% of personal insurance 
new business transactions handled electronically and 
78% of policy changes.  

(cid:2) Moved our claim systems to a new technology platform 
which should improve our ability to manage vendors,  
increase productivity and better control claim costs.
Weʼve taken the first step by introducing new wireless 
technology and new business processes to our field 
claims organization, which will enhance day-to-day  
claim handling service and streamline our response 
to catastrophes.

(cid:2) Redesigned our Business Owners Product (BOP), 

increasing eligibility for larger “Main Street” businesses, 
broadening risk classifications and introducing new  
sophisticated rating techniques and Web-based
rate/quote tools for our agents.  We expect this  
new product will be ready for implementation by  
mid-year 2007. 

(cid:2) Reviewed and refined authority levels for all business
insurance and personal insurance field personnel to 
ensure the right balance between appropriate empow- 
erment and greater customer responsiveness.

(cid:2) Implemented a variety of billing and customer service 
enhancements including a wider array of electronic  
payment processing options.

(cid:2) Began writing business in Arizona, our 27th state, and 

Colorado, our 28th state.

We have our work cut out for us in 2007.  While our
strategy is simple, our execution must be flawless and
fast.  We will build out the infrastructure necessary to
stimulate organic growth and sustain our legacy of strong
earnings.  We will further develop our strong risk manage-
ment capability.  And we will review and assess the quali-
ty of our capital management strategies.  Iʼm confident
that we have the leadership capability, management
depth and quality people necessary to do the job – and
do it well!  We are building on a strong foundation.  And
we have a bright future.

Sincerely,

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

Item 1. Business

(a) General Development of Business

PART I

State Auto Financial is an Ohio domiciled super-regional property and casualty insurance holding company
incorporated in 1990. We are primarily engaged in writing both personal and business lines of insurance. 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. Our operations are headquartered in Columbus, Ohio.

1

Our parent company, State Auto Mutual, is an Ohio domiciled super-regional mutual property and casualty
insurance company organized in 1921. It owns approximately 65% of State Auto Financial’s outstanding
common shares. It also owns 100% of SA Florida and SA Wisconsin, each of which is a property and casualty
insurance company. It 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. 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 share ownership of 518 PML, which owns and leases property to affiliated
companies. The results of the operations of S.I.S. and 518 PML are not material to our total operations.

State Auto P&C has participated in a quota share reinsurance pooling arrangement with our parent company
since 1987 (the “Pooling Arrangement”). Since January 1, 2005, the participants in the Pooling Arrangement
have been State Auto P&C, State Auto 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 property insurance, through approximately 2,900 independent
insurance agencies in 28 states. Our Pooled Companies and SA National are rated A+ (Superior) by the A.M.
Best Company.

(b) Financial Information about Segments

During 2006, we continued to operate our business in two significant reportable segments: standard
insurance and nonstandard insurance. Financial information about our segments for 2006 is set forth in Note 15
to our Company’s Consolidated Financial Statements included in Item 8 of our Form 10-K. Additional
information regarding our Company’s insurance and noninsurance segments is provided in “Narrative
Description of Business.” Under the leadership of Robert P. Restrepo, Jr., our new Chairman, President and
Chief Executive Officer, 2006 became a transitional year for the State Auto Group as we undertook initiatives to
realign our internal organization, specifically our people, processes, internal reporting systems and compensation
reward programs to become more focused within the business and personal insurance markets. While 2007 will
continue to be a transitional year in certain areas of our Company, we have already implemented integrated
personal and business insurance teams with product, profit and production responsibilities for their respective
areas. As a result of these transitional efforts, beginning in 2007, our significant reportable segments will change
from standard and nonstandard insurance to personal insurance and business insurance along with a third
segment for investment operations, and we will begin reporting on those bases to our chief operating decision
makers.

(c) Narrative Description of Business

Property and Casualty Insurance

Pooling Arrangement

Our 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.” Since January 1, 2005,
the Pooling Arrangement has been governed by the reinsurance pooling agreement known as the “2005 Pooling
Agreement.” The Pooling Arrangement covers all the property and casualty insurance written by our Pooled
Companies except voluntary assumed reinsurance written by our parent company, State Auto Middle Market

2

Insurance (as defined in the 2005 Pooling Agreement) and intercompany catastrophe reinsurance written by State
Auto P&C. Under the Pooling Arrangement, each of our Pooled Companies cedes premiums, losses and
expenses on all of their business to State Auto Mutual, which in turn cedes to each of our Pooled Companies a
specified portion of premiums, losses and expenses based on each of their respective pooling percentages. State
Auto 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, 1996:

is not management’s current

In the aggregate, the pooling percentages for our Pooled Companies have remained at an 80% participation
level since 2001. It
to our Pooled
Companies’ aggregate participation percentage in the foreseeable future. Under applicable governance
procedures, if the 2005 Pooling Arrangement were to be amended, management would make recommendations
to the independent committees of the Board of Directors of both State Auto Mutual and STFC. The independent
committees review and evaluate such factors as they deem relevant and recommend any appropriate pooling
change to the Board of Directors of both State Auto Mutual and us. The Pooling Arrangement is terminable by
any of our Pooled Companies at any time after a 90-day notice or by mutual agreement of our Pooled
Companies. None of our Pooled Companies currently intends to terminate the Pooling Arrangement.

intention to recommend an adjustment

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

3

to produce more uniform and stable underwriting results for each of our Pooled Companies than any one
company would experience individually. One effect of the Pooling Arrangement is to provide each of our Pooled
Companies 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 our Pooled Companies in the amount of $100.0
million in excess of $135.0 million after June 30, 2006 ($120.0 million prior to July 1, 2006), 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 2006, 2005 or 2004. See “Narrative Description of
Business—Reinsurance” in this Item 1 for further information regarding the Catastrophe Assumption Agreement.

Nonstandard Auto Insurance

We write nonstandard auto insurance through SA National. Nonstandard automobile programs provide
insurance for private passenger automobile risks which do not qualify for the standard or preferred automobile
insurance market. Typically, nonstandard risks have higher than average loss experience and an overall higher
degree of risk than standard or preferred automobile business. We do not include the business of SA National in
our Pooling Agreement. See “Narrative Description of Business—Marketing” and “Reportable Segments” in this
Item 1 for further information regarding our nonstandard auto insurance business.

Management Agreement

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

Each of the affiliated management and cost sharing agreements has a ten-year term, except for the SA
Florida cost sharing agreement, which has a five-year term. The SA Florida cost sharing agreement expires in
2007 and is renewed by mutual consent of the parties. The other cost sharing agreements automatically renew for
an additional ten-year period unless terminated sooner in accordance with their terms. If the 2005 Management
Agreement would be terminated for any reason, we would have to relocate our facilities to continue our
operations. However, we do not currently anticipate the termination of the 2005 Management Agreement.

Reportable Segments

See Note 15, Reportable Segments, of the Notes to our Consolidated Financial Statements included in

Item 8 of our Form 10-K and Item 7 of our Form 10-K.

Marketing

As of January 31, 2007, the State Auto Group marketed its standard products in 28 states (Colorado being
our 28th state of operation beginning January 2007) through approximately 2,900 independent
insurance
agencies. None of the companies in the State Auto Group has any contracts with managing general agencies. As
of January 31, 2007, SA National marketed its nonstandard auto products in 22 states exclusively through our
network of independent agents. We anticipate continued state expansion for our products during 2007.

4

Because independent insurance agents generally choose which products they recommend and provide their
customers, we view our independent insurance agents as our primary customers. We strongly support the
independent agency system and believe that maintenance of a strong agency system is essential to our present
and future success. As such, we continually develop programs and procedures to enhance our 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.

We actively help our agencies develop professional sales skills within their staffs. Our training programs
include both products and sales training conducted in our home office. Further, our training programs include
disciplined follow-up and coaching for an extended time. Other targeted training sessions are held in our branch
office locations from time to time.

We have made continuing efforts to use technology to make it easier for our agents to do business with us.
We offer internet-based (i) rating, (ii) policy application submission and (iii) execution of changes to policies for
certain products. In addition, we provide our 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 our agents and us to take advantage of electronic data submission. We believe that, since
agents and their customers realize better service and efficiency through automation, they value their relationship
with us. Automation can make it easier for an agent to do business with us, which attracts prospective agents and
enhances existing agencies’ relationships with us.

We share the cost of approved advertising with selected agencies. We provide our agents with defined travel
and cash incentives if they achieve certain sales and underwriting profit levels. Further, we recognize our 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 our Agent Stock Purchase Plan described below.

To strengthen agency commitment

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

We receive premiums on products marketed in Alabama, Arizona, Arkansas, Colorado, 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 2006, the seven states that contributed the greatest percentage of
our direct premiums written were as follows: Ohio (17.6%), Kentucky (11.2%), Indiana (7.6%), Tennessee
(6.7%), Minnesota (5.5%), Pennsylvania (5.0%) and Maryland (5.0%).

Claims

Insurance claims on policies written by us are usually investigated and settled by staff claims adjusters. Our
claims division emphasizes timely investigation of claims, settlement of meritorious claims for equitable
amounts, maintenance of adequate case reserves for claims, and control of external claims adjustment expenses.
Achievement of these goals supports our marketing efforts by providing agents and policyholders with prompt
and effective service.

5

Claim settlement authority levels are established for each adjuster, supervisor and manager based on his or
her level of expertise and experience. Our 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 our home office to be supervised by claims
division specialists. Branches with low volumes of large claims are assigned a lower dollar threshold for
referring claims to the home office. In territories in which there is not sufficient volume to justify having full-
time adjusters, we use independent appraisers and adjusters to evaluate and settle claims under the supervision of
claims division personnel.

We attempt to minimize claims adjusting costs by settling as many claims as possible through our 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.

Our claim representatives use third party, proprietary bodily injury evaluation software to help them value
bodily injury claims, except for the most severe injury cases. Our Claims Contact Centers allow us to improve
claims efficiency and economy by concentrating the handling of smaller, less complex claims in a centralized
environment. We provide 24 hour, seven days a week claim service, either through associates in our 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 we expect 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 results of our 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.

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 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,
changes in exposure units, 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 our 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. For additional information regarding our reserves, see
Item 7 of this Form 10-K, “Management, Discussion and Analysis of Financial Condition and Results of
Operations—Loss and Loss Expense Reserves.”

State Auto P&C’s December 31, 1990 liability for losses and loss expenses of $65.5 million has been
guaranteed by State Auto Mutual. Pursuant to the guaranty agreement, all ultimate adverse development of the
December 31, 1990 liability, if any, is to be reimbursed by State Auto Mutual to State Auto P&C in conformance
with pooling percentages in place at that time. Through December 31, 2006, there has been no adverse
development of the guaranteed liability. As of December 31, 2006, the remaining loss and loss expense liability
is estimated to be $0.9 million.

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. See discussion regarding the calendar year developments at Item 7 of our Form 10-K Management’s Discussion and
Analysis section at “2006 Compared to 2005—Expenses” and “2005 Compared to 2004 – Expenses.”
Includes amounts due from affiliates of $2.7 million, $5.5 million, and $5.7 million at end of year 2006, 2005, and 2004, respectively.

The following table sets forth our development of reserves for losses and loss expenses from 1996 through
2006. “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 us.

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, 2006, we have paid 90.0% of
the currently estimated losses and loss expenses that had been incurred, but not paid, as of December 31, 1997.

7

The amounts on the “cumulative redundancy (deficiency)” line represent the aggregate change in the
estimates over all prior years. For example, the 1997 calendar year reserve has developed a $23.2 million or
11.9% deficiency through December 31, 2006. 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
1999, but incurred in 1996, will be included in the cumulative redundancy or deficiency amounts for years 1997,
1998 and 1999. 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 1998, 1999, 2000 and 2001 the Pooling Arrangement was amended to increase our share of premiums,
losses and expenses and in 2005 to add the business of two companies within the State Auto Group, the MIGI
Insurers. An amount of assets equal to the increase in net liabilities was transferred to us from our parent
company in 1998, 1999, 2000 and 2001 in conjunction with each year’s respective pooling change and in 2005
from our subsidiaries, the MIGI Insurers. The amount of the assets transferred in 1998, 1999, 2000, 2001 and
2005 has been netted against and has reduced the cumulative amounts paid for years prior to 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 $3.0 million of each covered loss,
and the reinsurers are responsible for 100% of the excess over $3.0 million up to $20.0 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 95% 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 $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.

Members of the State Auto Group maintain property catastrophe reinsurance for catastrophic events
affecting at least two risks. On a combined basis, the members of the State Auto Group retain the first $55.0
million of catastrophe loss, each occurrence, with a 5% co-participation on the next $80 million of covered loss,
each occurrence. The reinsurers are responsible for 95% of the excess over $55.0 million up to $135.0 million of
covered losses, each occurrence. The rates for this reinsurance are negotiated annually.

Excess of the property catastrophe reinsurance described immediately above, the members of the State Auto
Group participate in an intercompany catastrophe reinsurance program (the “Catastrophe Assumption
Agreement”). Under the terms of the Catastrophe Assumption Agreement our subsidiary, State Auto P&C, acts
as the catastrophe reinsurer for the State Auto Group, and is responsible for up to $100.0 million of covered loss,
each occurrence in excess of $135.0 million of covered loss, each occurrence. Each reinsured company pays a
premium to our subsidiary, State Auto P&C, in exchange for the reinsurance coverage provided. There have been
no losses assumed under this agreement.

In 2005, we entered into a credit agreement with a financial institution and a syndicate of other lenders
which provides us with a $100.0 million five-year unsecured revolving credit facility referred to as the “Credit
Facility”. During the term of the Credit Facility, we have 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, we intend to use the Credit
Facility for catastrophe loss purposes. 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 Credit Facility.

As of July 1, 2005, SA National and State Auto Mutual terminated their reinsurance agreement. While this
reinsurance agreement was in effect, State Auto Mutual assumed up to $4.95 million of each liability loss
occurrence in excess of SA National’s $50,000 of retention and up to $450,000 of each catastrophe loss
occurrence in excess of SA National’s $50,000 of retention. State Auto 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 State Auto 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, State Auto Mutual continued to be liable, for up to one year, with respect to policies in force at
the termination date, for occurrences until the expiration, cancellation, or next anniversary of each such policy.

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 our 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 our 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 our holding company system, and require prior
notice and an opportunity to disapprove of certain “extraordinary” transactions, including, but not limited to,
extraordinary dividends to stockholders. Pursuant to these laws, all transactions within our 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 of our insurance
companies is subject to supervision and regulation in the states in which we transact 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

11

these companies’ 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.

We are required to file detailed annual reports with the supervisory agencies in each of the states in which

we do business, and our 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. Our insurance subsidiaries generally are restricted by the insurance laws of our respective states
of domicile as to the amount of dividends we may pay without the prior approval of our 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 $140.8 million is available for payment as a dividend from our subsidiaries, State Auto P&C, Milbank,
Farmers, SA Ohio and SA National during 2007, less dividend payments made in the previous twelve month
period without prior approval from our respective domiciliary state insurance departments. STFC received no
dividends in 2006 from its insurance subsidiaries. In 2005 and 2004, STFC received dividends of $40.5 million
and $12.0 million respectively, from its insurance subsidiaries.

Rates and Related Regulation. Except as discussed below, we are not aware of the adoption of any adverse
legislation or regulation in any state in which we conducted business during 2006 which would materially impact
our business.

During an emergency session in January 2007, the Florida legislature passed and the Governor signed into
law a bill known as “CS/HB-1A.” This new law makes fundamental changes to the property and casualty
insurance business in Florida and undertakes a multi-pronged approach to address the cost of residential property
insurance in Florida. First, the new law requires insurance companies to lower their Florida premium rates for
residential property insurance. The new law also authorizes the state-owned insurance company, Citizens
Property Insurance Corporation (“Citizens”), to reduce its premium rates and begin competing against private
insurers in the residential property insurance market and expands the authority of Citizens to write commercial
insurance. Previously, Citizens was the insurer of last resort for residential property insurance because its
required premium rates were higher than those generally available in the market place from private insurers. The
new law also empowers the State of Florida to assess Citizens’ underwriting losses against many lines of
property and casualty insurance written for Florida residents, including auto insurance. The State of Florida also
issued an order that essentially prevents insurance companies from non-renewing residential property insurance
policies until after the 2007 hurricane season. We are evaluating the ramifications of CS/HB-1A, specifically
regarding property insurance rates that we believe are inadequate to cover the related underwriting risk.
Additionally, we are concerned about competing against a state-owned insurance company and the expansion of
this possible type of solution to other states where the affordability and, in some instances, the availability of
coastal property insurance is an issue. When the cost or availability of insurance becomes a political issue, we
believe it can disrupt the marketplace and make underwriting results more volatile.

Several states where we write 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 us price our products more fairly and enhance our ability to compete for business
that we believe will be profitable. Such regulations would limit our ability, 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 to whether or not credit scoring has a
disparate impact on protected classes. The results of this study, which have not been published as of our filing of
this Form 10-K, could affect the industry’s use of this tool.

different lines of insurance, as well as investment risks that attend insurers’ operations, the National Association

requirements. As of
December 31, 2006, each insurer affiliated with us 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
unfavorably impact an insurer.

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, we intend, 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 multi-peril. In addition, TRIEA had the effect of increasing insurers’ deductible and
co-pay percentages under this federal program. Our current property reinsurance treaties exclude certified acts of
terrorism. If the Terrorism Acts expire at the end of 2007 those treaties may be revised to exclude acts of
terrorism as defined within the treaties. Likewise, if the Terrorism Acts expire, we may pursue changes to our
direct commercial policies to exclude acts of terrorism as defined within our policies.

An area of regulatory focus in recent years and which may continue to receive additional attention in 2007 is
“producer compensation arrangements.” The New York Attorney General as well as other states’ Attorneys
General undertook investigations and initiated lawsuits involving allegations of improper compensation
arrangements between brokers and insurance companies. These actions 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. Three state insurance departments delivered inquiries to us,
and we responded to each of the inquiries. It is our understanding that these inquiries were 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 we had done anything
improper with respect to our compensation arrangements with our agents. No action has been taken against us by
any of the states which made these inquiries.

Improper producer compensation arrangements generally involve insurance brokers, who are persons
retained and compensated by the insurance customer. We market our insurance products through independent
insurance agents who have been appointed to act on our behalf, and we, not the insurance customer, compensate
these agents pursuant
to contractual arrangements. Under our agency agreements, our compensation
arrangements with our agencies consist of commissions paid for the sale of our 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 and production volume generated by that

13

agency’s book of business placed with the State Auto Group. Like many other sales organizations, we also offer
sales incentives to our agencies. We believe that our agent compensation arrangements are in compliance with
the law and consistent with good business practices.

The Attorneys General of New York, Illinois and Connecticut settled producer compensation issues with
some insurers we compete against and these settlements included an obligation for these insurers to terminate
contingent commission compensation with their agents and brokers under certain circumstances. One such
circumstance was a determination by the Attorneys General party to these settlements that companies with at
least a 65% market share of property casualty insurance did not pay contingent commission. In the fall of 2006,
that threshold was passed and two major insurers we compete against, Travelers and Chubb, announced their
intention to terminate contingent commission compensation for agents and brokers in most lines of personal and
business insurance, respectively, in compliance with the terms of the settlement agreement described above. This
is a potentially significant development, the consequences of which cannot be fully foreseen at this time;
nevertheless, we continue to believe that our agent compensation programs comply with applicable law.

Investments

Our 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. Our investment portfolio is
managed separately from that of our parent company and its subsidiaries, and investment results are not shared
by our Pooled Companies through the Pooling Arrangement. Stateco performs investment management services
for us and our parent company and our subsidiaries, although investment policies implemented by Stateco
continue to be set for each company through the Investment Committee of our Board of Directors.

Our 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) our liquidity requirements at any given time; and (f) our current federal income tax position and relative
spread between after tax yields on tax-exempt and taxable fixed income investments. We have investment policy
guidelines with respect to purchasing fixed income investments for our insurance subsidiaries which preclude
investments in bonds that are rated below investment grade by a recognized rating service. Our 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 our 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 our investment portfolio.

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

Our Investment Policy and Guidelines permit investment in debt issues rated A or better by two major rating
services. Our 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, 2006 and 2005, our bond portfolio had a fair value
that totaled $1,647.4 million and $1,617.3 million, respectively.

At December 31, 2006 and 2005, our equity portfolio was classified as available-for-sale and carried at fair

value totaling $284.2 million and $255.6 million, respectively.

Competition

The property and casualty insurance industry is highly competitive. We compete with numerous insurance
companies, many of which are substantially larger and have considerably greater financial resources. In addition,
because our products are marketed exclusively through independent insurance agencies, most of which represent
more than one company, we face competition within each agency. See “Narrative Description of
Business—Marketing” in Item 1 and “Distribution System” and “Competition” included Item 1A of our Form
10-K. We compete through underwriting criteria, appropriate pricing, quality service to our policyholders and
our agents, and a fully developed agency relations program.

Employees

As of February 28, 2007, we had 2,060 employees. Our employees are not covered by any collective

bargaining agreement. Management considers the relationship with our employees to be excellent.

Item 1A. Risk Factors

Statements contained in our 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 our operating results to differ materially from those projected. The following
in some cases have affected, and in the future could affect, our actual financial
factors, among others,
performance.

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
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, tornadoes, windstorms, earthquakes, severe winter weather and fires, none of
which are within our control. Catastrophe losses can vary widely and could significantly impact our 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, earthquakes and other perils 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 and farmowners, other personal

17

lines, allied lines and commercial multi-peril coverages. The geographic distribution of our business subjects us
to catastrophe exposure from tornadoes, 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 three years, the largest catastrophe or series of catastrophes to affect STFC’s results of operations in any one
year were as follows: 2006 with losses that occurred in April from a series of tornadoes, hailstorms and
windstorms that caused damage in several of our Midwest operating states resulting in approximately $51.8
million in pre-tax losses; 2005 with losses from hurricanes Katrina and Wilma resulting in approximately $41.7
million in pre-tax losses; and 2004 with losses from hurricanes Charley, Frances, Jean and Ivan resulting in
approximately $39.6 million in pre-tax losses.

We believe that increases in the value and geographic concentration of insured properties 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 exposures 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 financial results depend 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, selection and application of appropriate rating formulae or other pricing
methodologies;

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;

18

•

•

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 PERSONAL LINES AUTO MARKET

The nonstandard personal lines auto market may be shrinking due to refined segmentation by key

competitors

In recent 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-variate rating models, which we believe has resulted in a shrinking 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
private passenger auto line 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 auto lines will not continue as a result of
the changes taking place in the nonstandard auto market and our own implementation of more inclusive
marketing and underwriting programs in the standard auto lines.

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 business insurance, 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 result in higher prices and more restrictive contract and/or coverage
terms. 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

19

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. Our Company and other personal lines insurers may be unable to increase premiums at the same pace as
coverage costs increase. Accordingly, profit margins generally decline in periods of increasing loss costs.

DISTRIBUTION SYSTEM

The independent agency system is the 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 techniques, the internet or “captive”
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, bankruptcies and agent retirements. We also recognize that
it will be
to expand the number of independent agencies representing us. If we are
progressively more difficult
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 prices 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 prices to grow top line sales. Consequently, we must remain focused on attracting and
retaining productive agents to market and sell our products. We compete 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.

We also expect that there will be consequences from certain of our competitors eliminating contingent
commissions to agents as a result of legal actions undertaken by certain states’ Attorneys General. It may be that
these or other Attorneys General will pursue other insurers who are continuing to pay contingent commissions or
it may be that these insurers will develop alternative compensation structures to replace contingent commissions
that may be perceived as more attractive to independent agents, thus driving the marketplace to move in that
direction. It may also be that these large insurers will seek to level the playing field for independent agent
compensation by lobbying for regulatory or legal changes to prohibit or restrict so-called contingent commissions
and other sales incentive compensation.

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 stockholders and other investors, and
limitations,
relates to authorization for lines of business, capital and surplus requirements,

investment

20

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. The NAIC and
state insurance regulators are constantly reexamining existing laws and regulations, generally focusing on
modifications to holding company regulations, interpretations of existing laws and the development of new laws.

From time to time, some states in which we conduct business have considered or enacted laws that may alter
or increase state authority to regulate insurance companies and insurance holding companies. In other situations,
states in which we conduct business have considered or enacted laws that impact the competitive environment
and marketplace for property and casualty insurance. For example, Florida recently enacted legislation that
requires us to charge rates for homeowners insurance that we believe are inadequate to cover the related
underwriting risk. This same legislation authorizes a state-owned insurance company to reduce its premium rates
and begin competing against private insurers in the Florida residential property insurance market.

Currently the federal government does not directly regulate the insurance business. However, in recent years
the state insurance regulatory framework has come under increased federal scrutiny. 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. In
addition, changes in federal legislation and administrative policies in several areas, including changes in the
Gramm-Leach-Bliley Act, financial services regulation and federal
the
insurance industry and us.

taxation, can significantly impact

We cannot predict with certainty the effect any enacted, proposed or future state or federal legislation or
NAIC initiatives may have on the conduct of our business. Furthermore, there can be no assurance that the
regulatory requirements applicable to our business will not become more stringent in the future or result in
materially higher costs than current requirements. Changes in the regulation of our business may reduce our
profitability, limit our growth or otherwise adversely affect our operations.

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. 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 making claims for an event that would otherwise not be covered by their
insurance policies. The principal focus of these lawsuits, including one lawsuit being brought by the attorney

21

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, reduced economic
activity, and additional disruptions to commerce. 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 stockholders’ 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. If the policyholder rejects coverage for 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. See “Narrative
Description of Business-Regulation” of this Item 1 for a discussion of the Terrorism Acts.

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 business insurance lines automated underwriting tools may not be successful or the

benefits may not be realized.

We are developing a business insurance lines automation system that will build upon the success we believe
we have achieved through our personal lines netXpress system. Our netXpress allows agents to obtain personal
lines rates for applicants on-line in real time and secure consumer reports required for rating or underwriting.
This report availability enables our agents to offer a firm quote to a customer in real time at the point of sale. It is
our intention to develop similar functionality for business insurance 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 business lines. We cannot be sure 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 and 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 cause the investments in our pension plans to decrease
below the accumulated benefit obligation, resulting in additional 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 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 our 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
facilities, a power outage, a pandemic, 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

23

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 infrastructure, 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 State Auto 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 State
Auto Mutual will continue to pursue acquisitions of other insurance companies in the future. In December 2006,
State Auto Mutual, through MIGI, announced its intent to acquire the Beacon Insurance Group of Wichita Falls,
Texas. A first quarter 2007 closing is anticipated, conditional upon regulatory approval.

Acquisitions involve numerous risks and uncertainties, such as:

•

•

•

•

•

•

•

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

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
agencies to insurers based upon factors that they believe are relevant to policyholders and creditors. Ratings are

24

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. Our Pooled Companies and
SA National 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 OUR PARENT COMPANY

Our parent company owns a significant interest in us and may exercise its control in a manner

detrimental to your interests.

As of December 31, 2006, our parent company owned approximately 65% of the voting power of our
Company. Therefore, State Auto Mutual has the power to direct our affairs and is able to determine the outcome
of substantially all matters required to be submitted to stockholders for approval, including the election of all our
directors. State Auto Mutual could exercise its control over us in a manner detrimental to the interests of other
STFC stockholders.

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 we. 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 and name or brand recognition. Our competitors sell through various distribution channels, including
independent agents, captive agents and directly to the consumer. We compete not only for business insurance
customers and personal insurance 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 1B. Unresolved Staff Comments

None.

Item 2. Properties

We share our operating facilities with State Auto Mutual pursuant to the terms of the 2005 Management
Agreement. Our corporate headquarters are located in Columbus, Ohio, in buildings owned by State Auto Mutual
that contain approximately 280,000 square feet of office space. Our Company and State Auto Mutual also own
and lease other office facilities in numerous locations throughout the State Auto Group’s geographical areas of
operation.

Item 3. Legal Proceedings

We are a party to a number of lawsuits arising in the ordinary course of our insurance business. Our
Management believes that the ultimate resolution of these lawsuits will not, individually or in the aggregate, have
a material, adverse effect on our financial condition.

Item 4. Submission of Matters to a Vote of Security Holders

None.

OVERVIEW

State Auto Financial is a property and casualty insurance holding company primarily engaged in writing
both personal and business lines of insurance. The State Auto Group writes a broad line of property and casualty
insurance products through approximately 2,900 agencies in 28 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 property to affiliated companies. S.I.S and 518 PML are not material to our total
operations.

State Auto Mutual owns approximately 65% of State Auto Financial’s outstanding common shares. State
Auto 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. State Auto 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 provide a broad line of property and casualty insurance, such as standard personal
and commercial automobile, homeowners and farmowners, commercial multi-peril, workers’ compensation,
general liability and property insurance. SA National provides nonstandard personal automobile insurance to the
nonstandard insurance market.

Our Pooled Companies and SA National are rated A+ (Superior) by the A.M. Best Company.

The STFC Pooled Companies participate in a quota share reinsurance pooling arrangement (the “Pooling
Arrangement”) with the Mutual Pooled Companies. The Pooling Arrangement covers all the property and
casualty insurance written by the Pooled Companies except voluntary assumed reinsurance written by State Auto
Mutual, State Auto Middle Market Insurance (as defined in the current pooling agreement among the Pooled
Companies) 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 State
Auto Mutual, and State Auto 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. State
Auto 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 MIGI Insurers as participants. In
conjunction with this amendment, the STFC Pooled Companies received $54.0 million in cash from the MIGI
Insurers which related to the additional net insurance liabilities assumed on January 1, 2005.

Time period is for the year ended December 31.

Prior to January 1, 2007, we operated in two significant reportable segments. State Auto P&C, Milbank,
Farmers and SA Ohio comprised the standard segment of our operations, and SA National comprised the
nonstandard segment. Under the leadership of Robert P. Restrepo, Jr., as our new Chairman, President and Chief
Executive Officer, 2006 became a transitional year for the State Auto Group as we undertook initiatives to
realign our internal organization, specifically our people, processes, internal reporting systems and compensation
reward programs, to become more focused within the business and personal insurance markets. While 2007 will
continue to be a transitional year in certain areas of our Company, we have now established integrated personal
and business insurance teams with product, profit and production responsibilities for their respective areas. As a
result of these transitional efforts, beginning in 2007, our significant reportable segments will be personal and
business insurance along with a third segment for investment operations, and we will begin reporting on these
bases to our chief operating decision makers. Financial information about our segments for 2006 is set forth in
Note 15 to the Company’s Consolidated Financial Statements included in Item 8 of the Form 10-K.

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 selecting and pricing risks in a manner that permits premium growth without adversely
affecting underwriting profits, and disciplined investment strategy. We also recognize that our results will be
periodically impacted, sometimes significantly, by the occurrence of catastrophic events, which are generally
beyond our control.

•

Premium Growth/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 result in
increased prices and more favorable underwriting terms. 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 long term underwriting profitability. Our strategy 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 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.

•

Investment Strategy: We have a disciplined approach to our investment strategy that emphasizes the
quality of our fixed income portfolio, which comprised 85% of our total portfolio at fair value at

30

•

•

December 31, 2006, and includes only investment grade securities. Our equity portfolio, which
comprised approximately 15% at fair value of our total portfolio at December 31, 2006, 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.

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,
circumstances and historical
trends then known. 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 level of adequacy and also minimizes the
impact that any required adjustment may have on our current operating results.

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. Many catastrophes are restricted to small geographic areas. However,
hurricanes, earthquakes and other perils 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, which include obtaining reinsurance. 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 28 states in 2007. In early 2007, we began writing personal
insurance in the state of Colorado, our 28th state of operation. 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 17.6% for the year ended December 31, 2006. We carefully
monitor writing insurance in states that we believe present difficult
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 and environmental claims. Our catastrophe
management strategies are designed to mitigate our exposure to earthquakes and hurricanes.

legislative,

In addition to our adherence to our cost-based pricing, investment and risk mitigation strategies, discussed
above, our management focuses on several other key areas with the intention of continually improving the results
of our operations and financial results, including the following:

•

•

Claims Service: We believe an important element of our success is our focus on claims service. We
expect our claim service to be fair, fast and friendly. The role of the claims division is to deliver the
promise that we and the independent agent made to the insured. 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 of a claim being assigned to a claims handler (except in
catastrophe loss situations).

Independent Insurance Agent Network: We offer our products through approximately 2,900 agencies
in 28 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,

31

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
incentives and agency
programs, an agent’s stock purchase program, profit-sharing and travel
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 agency relationship. Our senior management regularly makes themselves 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.

•

Technology: 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 which improves the agents “ease of doing business” with us.

Statistics for 2006 indicate that 94% (up from 84% in 2005) of our personal automobile and
homeowners new business applications were delivered to us electronically. This resulted in an
additional 19,000 policies being sent to us electronically in 2006 over 2005. In regards to policy change
requests, 78% were processed electronically by our agents in 2006 compared to 67% in 2005. This
represents 32,000 more policy changes done electronically by agents in 2006 over 2005.

The Apollo system allows us to be better able to make consistent underwriting decisions across
personal auto and homeowners products. In 2006, we expanded the use of this system to additional
states, additional products, and added the automated review of claims transactions. In 2006, more than
282,000 transactions (new business, endorsements, cancellations, and claims transactions) were
reviewed by Apollo. Of those, 174,000 of them were automatically accepted by business rules
established within Apollo.

Management continued to focus in 2006 on improving our 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 and third
party application tools that our agents use.

We added two new underwriting tools in 2006. Our youthful driver identification tool, which works to
identify youthful operators at the earliest possible point without the need to rely on agents or
policyholders, is now being used in nine of our nonstandard personal automobile insurance states and
11 of our standard personal automobile insurance states. Youthful operators, as inexperienced drivers,
tend to produce a disproportionate number of losses. Our ability to identify these drivers early and
charge the appropriate premium should improve our profitability on these accounts. We also introduced
a property protection class tool in 20 states. This tool verifies the accuracy of the fire protection class
for a given risk which will assist in providing more appropriate underwriting.

The “AgentSite Dashboard” was enhanced to provide agents with even quicker access to customer
information and their recent transactions. This new functionality has helped agents transition following
our decision to eliminate the printing and mailing of paper policy declarations to agents for personal
insurance.

In 2006, we upgraded our enterprise billing and claims systems. Both of these applications now utilize
browser- based technology which replaced older, hard to maintain technology. We also increased the
methods by which insureds can make premium payments. Insureds can now pay online via our website
portal and by credit and debit cards. All of these methods have resulted in increased flexibility and
more satisfied customers. We also now receive nearly 15% of our new claims via our website portal.

In 2006, we began work to develop business insurance automation systems that are intended to build
insurance. We
upon the success we have achieved through our netXpress system for personal

32

modernized our business insurance policy administration system to allow straight through processing
which now results in a real time update capability. In order to achieve our goal of commercial lines
functionality equivalent to that provided by netXpress in personal insurance, we are making necessary
and appropriate investments in people and systems. We believe developing such an internet-based
system is vitally important to our ability to compete for new business insurance accounts. The goal is to
enable agents to offer a firm quote to a customer in real time at the point of sale for three of our major
business insurance products.

CRITICAL ACCOUNTING POLICIES

Our significant accounting policies are more fully described in Note 1 of the Notes to our Consolidated
Financial Statements included in Item 8 of this Form 10-K. 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 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.
We have identified the policies and estimates described below as critical to our business operations and the
understanding of the results of our operations.

Investments

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.

We regularly monitor our 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 our investment
portfolio has been determined to have a decline in fair value that is other-than-temporary, we adjust 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. For a further discussion regarding our investments see “Other—Investments”
included herein.

Deferred Acquisition Costs

Acquisition costs, consisting of commissions, premium taxes and certain underwriting expenses relating to
the production of property and casualty business, are deferred and amortized over the same period in which the
related premiums are earned. 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.

Losses and Loss Expenses Payable

Losses and loss expenses payable are management’s best estimates at a given point in time of what we
expect 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 our reserving practices, which

33

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. 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.

Loss and loss expense reserves for incurred claims 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. The process for calculating IBNR is to develop an estimate of the ultimate
losses incurred, and then subtract all amounts already paid or held in tabular case reserves. Although
management uses many internal and external resources, as well as multiple established methodologies to
calculate IBNR, there is no method for determining the exact ultimate liability. See further discussion regarding
our losses and loss expense reserves and our reserving methods see “Other—Loss and Loss Expense Reserves”
included herein.

Pension and Postretirement Benefit Obligations

Pension and postretirement benefit obligations are long term in nature and require management’s judgment
in estimating the factors used to determine these amounts. Management reviews these factors annually, 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. For a further discussion regarding our pension and postretirement benefit obligations see
“Other—Employee Benefit Plans” included herein.

Share-Based Compensation

We have share-based compensation plans which authorize the granting of various equity-based incentives
including stock options, restricted stock and restricted share units to employees and non-employee directors and
agents. The expense for these equity-based incentives is based on their fair value at date of grant or each
reporting date and amortized over their vesting period. The fair value of each stock option granted is estimated
on the date of grant or each reporting date using the Black-Scholes closed-form pricing model. The pricing model
requires assumptions such as the expected life of the option and expected volatility of our stock over the expected
life of the option, which significantly impacts the assumed fair value. We use historical data to determine these
assumptions and if these assumptions change significantly for future grants, share-based compensation expense
will fluctuate in future periods. For a discussion regarding our adoption of SFAS 123(R), “Share-Based
Payment” (“SFAS 123(R)”), effective January 1, 2006, see “2006 Compared to 2005—Expenses” included
herein.

Other

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.

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 consistently profitable from an underwriting
standpoint. We have consistently focused on producing an underwriting profit and, therefore, we view our
underwriting results during all market cycles as the most important measure of our overall operating performance.

35

We monitor the performance of our 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. U.S. 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. For a discussion of
deferred policy acquisition costs see “Critical Accounting Policies—Deferred Acquisition Costs” 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 2006, 2005 and 2004,

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, 2006, our insurance segments attained an underwriting
profit while also incurring significant levels of catastrophe losses in terms of dollars. Despite these catastrophe
losses, our core results remained strong which was the direct result of our maintaining adequate cost-based rates
and monitoring risk selection.

2006 Compared to 2005

Income before federal income taxes decreased $10.3 million (6.0%) to $161.7 million in 2006 from 2005.
The most significant factors contributing to this decrease relate to a decline in our revenues, specifically our
premiums, an increased level of catastrophe losses, and the recognition of share-based compensation expenses
beginning in 2006. In the face of increased industry-wide price competition, we did not grow the top line in 2006.
Our earned premiums declined $26.5 million or 2.5%, in 2006 from 2005. Catastrophe losses in 2006 were $91.2
million compared to $72.7 million in 2005. Share-based compensation expense, which we began to recognize in
2006, was $6.6 million. Each of these components is discussed more fully below.

Revenues

We measure top-line growth for our insurance segments based on written premiums, which represent the
premiums on policies we have issued for a period, net of reinsurance. Net written premiums provide us with an
indication of how well we are doing in terms of revenue growth before it is actually earned. The following table
provides a summary by segment and line of business of our written premiums, net of reinsurance, for the years
ended December 31, 2006 and 2005:

(1) Amounts have been adjusted to exclude the unearned premium transferred in connection with the addition of the MIGI Insurers to the

Pooling Arrangement. The addition of the MIGI Insurers to the Pooling Arrangement was effective January 1, 2005.

Standard segment net written premiums for 2006 decreased $19.6 million (2.0%) compared to 2005. The
decrease in net written premiums in the standard segment was attributable primarily to personal and commercial
auto which had a combined decrease in net written premiums of $21.5 million or 4.5%.

Competitive pressures within the standard personal auto market are impacting the writing of new and
renewal business and putting downward pressure on our existing rates. Standard personal auto, which accounts

37

for 35.5% of our book of business, continues to be our most profitable line of business. As a result of the
competitive market, we reduced our rates approximately 2.7% during 2006 in order to remain competitive
without significantly compromising our profitability.

We continue to focus on attracting new business to our standard personal auto line of business. The primary
product contributing to new business in standard personal auto is our CustomFitSM product which uses a
multi-variate rating approach that broadens the underwriting and eligibility guidelines for new customers. Having
price points for a larger percentage of the personal
is expected to improve new business
opportunities. As of the end of 2006, we had implemented CustomFitSM in 19 states, which represented
approximately 80% of our standard personal auto written premium volume. Since introducing CustomFitSM in
December 2005, we have seen a significant improvement in our net written premium production trend for new
business.

lines market

We believe independent agents value “ease of doing business” and make it an important factor in their
choice of insurance companies when quoting personal auto products to their customers. To assist in this area, in
2006, we entered into agreements with two major comparative rating companies. These companies’ products
allow agents to receive rate quotes from multiple insurance companies by entering the rating information only
one time. We worked diligently in the fourth quarter with these two vendors with a launch date for
implementation expected in early 2007. We believe agents will quote and write more personal standard and
nonstandard auto with us as a result of a more efficient quoting process combined with more competitive rates
resulting from the ongoing introduction of CustomFitSM for standard auto and new policy discounts introduced in
2006 for nonstandard auto.

Homeowners net written premium grew 1.6% in 2006. We are undertaking new homeowners pricing and
product initiatives, such as a new home purchase discount and an expanded new home discount that will
complement our CustomFitSM rollout and should position us well for the future. The competitive pressures that
have impacted personal auto have also extended to homeowners. In general, our homeowner rate level was
impacted (2.0)% due to downward rate changes.

Farmowners net written premium was down 5.4% in 2006. To improve our farmowners production, we
introduced our farmowners insurance products in Pennsylvania during the second quarter of 2006. Our
farmowners business is now active in eleven of our operating states. In addition, a new on-line farmowners rating
program was introduced in all eleven states during 2006. The rating program is expected to produce more new
business opportunities because we think this new system makes it easier for farm insurance agents to do business
with us.

During 2006, we enhanced our personal lines point of sale portal, netXpressSM. This is the system our
agencies use to send us business electronically. We now have real time, on-line information access capabilities
that streamline the new business quote and issue process. Approximately 94% of our personal auto and
homeowner lines new business was submitted electronically in 2006 compared to 84% in 2005. In addition in
2006, 78% of all personal auto and homeowner lines policy changes came to us electronically from agents.

Our business insurance book of business continues to be impacted by rate competition as well as ease of
doing business issues. Commercial auto net written premiums decreased 3.4% in 2006. However, commercial
multi-peril and workers’ compensation net written premiums reflected positive growth. In general, during 2006
the overall impact to net written premiums from business insurance line rate changes was a slight decrease.

We are pursuing initiatives that we anticipate will generate additional business insurance premium
production over the long term. One of our current strategic priorities is to develop a web-based rating system for
the three products that generate the most new business submissions. In addition, we are developing more
sophisticated pricing models to further segment our business insurance accounts, which we anticipate will
improve our growth opportunities while still achieving our profit targets. We are also emphasizing a total account

38

underwriting approach in which we offer additional products to our existing accounts. We are developing product
enhancements that we believe will result in increased sales while pursuing process efficiencies to deliver product
and pricing developments to the market more quickly. During 2006, we focused on introducing a more
marketable pricing structure without forfeiting underwriting profits. Finally, we increased field underwriting
authority which quickens our response to our agents.

Net written premiums in our nonstandard personal auto segment decreased $6.5 million (13.3%) in 2006.
However, the nonstandard personal auto segment is beginning to stabilize; in the fourth quarter of 2006, new
business increased 14.6% compared to the same period in 2005. The impact of target rate decreases coupled with
the introduction of new discounts has produced what appears to be an improving premium situation.

However, we believe the personal auto market is changing quickly and dramatically. Many companies are
moving to a single auto product (such as our CustomFitSM) which can accommodate most personal auto risks. As
a result, the delineation between standard and nonstandard auto insurance is becoming blurred. The new auto
programs accepting a broader range of risks has limited and is expected to continue to limit the nonstandard auto
market for us and other insurers.

For all our products, we continue to emphasize that 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 agents by stressing the strengths we bring to the marketplace. These
strengths include stability, financial soundness, prompt and fair claims service, and user-friendly technology
which help agents do business with us and provide substantial value to our customers. Our Internet-based point
of sale agency portal for personal lines business, netXpressSM, and our automated intelligent underwriting
system, Apollo, are examples of standards-based technology which makes it easier for agents to submit personal
lines accounts to us. During 2006, we added functionality for agents to acquire underwriting information reports
within netXpressSM in real time, thus streamlining their new business submission processes. Apollo has also been
enhanced in several ways, including the ability to efficiently and quickly underwrite new and developing claims
activity on our existing book of business.

Our policies provide a fixed amount of coverage for a stated period of time, often referred to as the “policy
term.” As such, our written premiums are recognized as earned ratably over the policy term The unearned portion
of written premiums, called unearned premiums, is reflected on our balance sheet as a liability and represents our
obligation to provide coverage for the unexpired terms of the policy. The following table summarizes our earned
premium revenue by segment and line of business for the years ended December 31, 2006 and 2005:

Net investment income increased $4.4 million (5.6%) to $83.1 million in 2006 compared to the same 2005
period. Strong underwriting results in 2005 and 2006 contributed favorably to cash flows, which allowed us to
increase the amount of our invested assets during 2006. Total cost of invested assets at December 31, 2006 and
2005 was $1,940.7 million and $1,856.5 million, respectively. Also impacting our 2006 results was the fact that
STFC paid off its $45.5 million line of credit with State Auto Mutual at the end of 2005, which had the effect of
decreasing net investment income for the year by approximately $2.0 million. The annual investment yield based
on average invested assets at cost was 4.4% in 2006 and 4.3% in 2005. We continue to allocate new monies and
reinvestments to tax-exempt bonds, targeting an allocation of 70% of our total portfolio, in an effort to maximize
our after tax investment income. During the fourth quarter of 2006, the Investment Committee of the Board of
Directors of each of our insurers approved a $50.0 million repositioning of the current taxable and tax-exempt
holdings intending to reach the targeted 70% tax-exempt allocation at a quicker pace. At December 31, 2006,
tax-exempt bonds accounted for 62% of our total portfolio versus 58% at December 31, 2005. Our after tax net
investment income grew to $69.8 million (16.1% effective tax rate) in 2006 compared to $65.2 million (17.3%
effective tax rate) in 2005.

We recognized $5.4 million in other-than-temporary impairments in 2006 compared to $1.6 million in 2005.
In 2006, we recognized $3.8 million of other-than-temporary impairments related to our investment in certain
subordinate income notes and principal protected units representing purchased beneficial interests in securitized
financial assets. We reduced our estimate of future cash flows we expect to receive from these securities in light
of actual default rates of the underlying collateral securities in excess of assumed defaults. Our carrying value of
these securities at December 31, 2006 was $1.6 million. We also recognized $1.6 million of other-than-
temporary impairment related to four of our equity holdings within the consumer sector. All four of these equity
positions were sold during 2006. The other-than-temporary impairments recognized in 2006 were limited to these
securities, based on specific facts and judgments related to these particular issuers.

Most of the realized gains during 2006 were derived from the equity segment of the portfolio. Equity sales
were executed during this time for various reasons, including achieving our price target. The proceeds from these
sales were mostly reinvested into equity securities of other companies. The realized gains on the fixed income
portfolio were achieved by selling shorter-term municipal bonds and subsequently reinvesting those funds into
longer term municipal bonds.

Expenses

Our consolidated losses and loss adjustment expenses, as a percentage of earned premiums (the “GAAP loss
and LAE ratio” or “loss ratio points”), were 57.4% and 58.4% for the years ended December 31, 2006 and 2005,
respectively. Our auto and liability lines produced better loss results during 2006 while the property lines
deteriorated due mostly to catastrophes. Our standard personal and commercial auto lines continued to produce
favorable GAAP loss and LAE ratios benefiting from a combination of cumulative rate changes taken over the
past several years along with improvement in claim frequency and severity. In addition, our focus on rate
adequacy and monitoring our independent agency partners’ performance, in terms of both growth and profit, has
enabled the nonstandard personal auto segment to consistently generate a net underwriting profit over the last
several years.

Catastrophes added 8.9 points ($91.2 million) to the 2006 loss ratio compared to 6.9 points ($72.7 million)
for 2005. During 2006, catastrophe losses included $51.8 million (5.1 points) in losses relating to three major
Midwestern storms that occurred in April. In 2005, hurricanes accounted for $42.9 million (4.1 points) of total
catastrophe losses.

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, we have also included in these
figures those losses that arise from an event, or series of related events, that we have internally defined as a
catastrophic event resulting in ultimate losses to the State Auto Group in excess of $2.0 million.

Normal fluctuations and uncertainty associated with loss reserve development and claim settlement
contributed to favorable development in the respective calendar years. As shown in the table above, the favorable
development of $71.7 million in 2006 came primarily from accident years 2003-2005. The following are the
notable items contributing to the 2006 development:

• We hold ceded loss reserves in anticipation of transferring liabilities to reinsurers and other pools and
associations. In 2006, ceded loss reserves developed favorably by $23.7 million, meaning the actual
ceded losses were above anticipated levels. Historically, we have had less ceded loss activity because
our reinsurance retention levels are generally high enough to exclude most claims. This favorable
development occurred primarily in the auto and commercial multi-peril lines.

•

Favorable development at the product level is primarily from the personal auto and commercial auto
liability lines, where current loss projections using more mature claim data resulted in lower expected
is $24.7 million for these two lines
average claim severities than past projections. The impact
combined.

42

•

•

Adjusting and other expense reserves(1) accounted for approximately $13.5 million of prior year reserve
change. These expense reserves have a proportional relationship to the overall claim inventory and held
reserves by accident year, as they move up or down in relation to carried loss reserves. Since reserves
decreased for the prior accident years, the expense reserves declined in a similar fashion.

The remaining favorable development is spread across several lines of business and is generally the
result of having fewer claims emerge and lower claim severity, than anticipated in the estimates

“Adjusting and other expense” is that component of loss expenses (ALAE and ULAE (both defined below)) that relate to costs other than
defense, litigation, and medical cost containment. Allocated loss adjustment expenses (“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. Unallocated loss
adjustment expenses (“ULAE”) are those costs incurred in settling claims, such as in-house processing costs, for which no identification
can be made to specific claims.

See discussion regarding the 2005 calendar year development at “2005 Compared to 2004—Expenses”
the

section included herein. See additional discussion regarding loss and loss expense reserves at
“OTHER—Loss and Loss Expense Reserves” section included herein.

As of January 1, 2006, we began recognizing compensation expense associated with share-based awards
granted to employees and non-employee directors within our financial statements in accordance with SFAS
123(R). Consequently, our 2006 expenses include additional share-based awards of $6.6 million associated with
the adoption of SFAS 123(R). Prior to January 1, 2006, we accounted for these awards in accordance with
Accounting Principles Board Opinion No. 25, “Accounting for Stock Issued to Employees” (“APB 25”) and
related Interpretations. We adopted the guidance provided by SFAS 123(R) under the modified prospective
transition method. Under this transition method, share-based compensation expense in 2006 includes the portion
vesting in the period for (1) all share-based awards granted prior to, but not vested as of January 1, 2006, based
on the grant date fair value estimated in accordance with the original provisions of FASB Statement SFAS 123,
“Accounting for Stock-Based Compensation” (“SFAS 123”), and (2) all share-based awards granted subsequent
to January 1, 2006, based on the grant date fair value estimated in accordance with the provisions of SFAS
123(R). Results for prior periods have not been restated.

Prior to January 1, 2006, we provided pro-forma disclosures as required under SFAS 123. The reader is
referred to the complete disclosure on share-based awards in Note 12, Share-Based Awards, of the Notes to our
Condensed Consolidated Financial Statements included in this Form 10-K. Our 2005 pro-forma earnings, as
reported in December 31, 2005 Form 10-K, included $0.14 diluted per share of share-based compensation
expense. For the year ended December 31, 2006, the comparable share-based awards are $0.12 diluted per share.
The expense for our share-based awards is based on their fair value at date of grant and amortized over the
vesting period. At December 31, 2006, there was $5.6 million of total unrecognized share-based compensation
expense related to non-vested service based awards. This expense is expected to be recognized as follows: $3.5
million in 2007; $1.7 million in 2008; and $0.4 million in 2009. Unearned share-based compensation is
amortized over the vesting period for the particular grant and is recognized as a component of loss and loss
adjustment expenses and acquisition and operating expenses in a manner consistent with other employee
compensation in the accompanying Condensed Consolidated Statements of Income.

The fair value of each stock option granted is estimated on the date of grant using the Black-Scholes closed-
form pricing model. The pricing model requires assumptions such as the expected life of the option and expected
volatility of our stock over the expected life of the option, which significantly impacts the assumed fair value.
We use historical data to determine these assumptions and if these assumptions change significantly for future
grants, share-based compensation expense will fluctuate in future periods.

Acquisition and operating expenses, as a percentage of earned premiums (the “GAAP expense ratio” or
“expense ratio points”), were 34.0% and 31.7% for the years ended December 31, 2006 and 2005, respectively.
The increase in our 2006 expense ratio is due in part to lower premiums in 2006 compared to 2005, expenses
associated with share-based awards under SFAS 123(R) (see previous discussion above), as well as expenses

43

related to our incentive programs, both agency and employee. These incentive programs are directly related to
our loss experience. We do not anticipate meaningful reductions in our expense ratio during 2007 as it relates to
our incentive compensation programs as well as our investment in new technologies and products as we position
ourselves to be more competitive in the market place.

Interest expense in 2006 was $7.4 million compared to $8.8 million in 2005. The decrease in interest
expense was largely due to our repayment to State Auto Mutual of a $45.5 million note at the end of 2005. The
amount of interest expense related to this $45.5 million note was $1.6 million in 2005. For a further discussion of
our debt arrangements, see “Liquidity and Capital Resources Borrowing Arrangements” included herein.

The 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. For 2006, the effective tax rate was 25.5% compared to 26.8% for 2005. As previously
discussed, the effective tax rate on net investment income has declined to 16.1% in 2006 compared to 17.3% in
2005, primarily due to increasing our tax-exempt municipal bond holdings throughout 2006.

2005 Compared to 2004

Our income before federal income taxes 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 our loss experience from
2004 along with growth in earned premium and net investment income. Our 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
our history in terms of dollars. As discussed in more detail below, our 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 MIGI 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

44

the MIGI 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 ours. We remain committed to achieving our 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. We constantly pursue rate adequacy while also working
to address unprofitable agencies. For example, over the last year, we have been working with a number of our
larger and fast growing agencies in the state of Minnesota where experience has not resulted in an underwriting
profit. As a result, we have recently taken corrective action and have 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, we believe we are 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 our 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-variate rate models by many competitors, the definition of a nonstandard risk is becoming
more nebulous. As a result, what may have once been perceived as a nonstandard risk may now qualify within
the standard market. We are responding by continuing to research and develop pricing enhancements to fit with
the nonstandard auto markets which have a higher potential for underwriting profit.

Our biggest challenge in 2005 was top line growth in both the standard and nonstandard segments. As a
consequence, we implemented a number of initiatives to stimulate sales in personal lines new business and are
working with our 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 our goal of at least 1,000 program participants during 2005. Additionally, we
continually review our insurance programs in order to provide insurance to a broader segment in the markets in
which we operate. For example, we have expanded eligibility requirements for youthful operators within our
standard segment and, as noted, are selectively offering higher limits within the nonstandard segment. Most
recently we began to roll out a new standard private passenger auto multi-variate rating program called
CustomFitSM—a program that is more responsive to the risk characteristics of each driver, more accurately
matching price to risk, and is intended to facilitate our agency partners’ ability to sell this program to a broader
segment of its customer base. The objective is to preserve our 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, we appointed 58 new agency partners. Each year we terminate our relationship with some agencies.
On occasion we have had to either terminate or suspend several fast growing but unprofitable agencies, as has
been the case within our nonstandard segment, but for the most part, an overwhelming number of the terminated
agencies are usually those that have very little premium with us. The average premium for the agencies
terminated in 2005 was $16,000.

We continue to emphasize that 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 brings to the marketplace. These
strengths include stability, financial soundness, prompt and fair claims service, and technology which make it

45

easier for the agent to do business with State Auto and provide substantial value to their customers. 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.

Recent statistics indicate that approximately 87% of our 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 our efforts to compete on “ease of doing business” are achieving success. The Apollo system
allows us 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.

We are addressing ease of doing business in other ways as well, including 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 the agents’
transition following our decision to eliminate the printing and mailing of paper policy declarations to agents for
personal lines.

Recently, the State Auto Group began developing a business insurance line automation system that will
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. It is the intention of the State Auto Group to develop similar functionality in business insurance lines.
This represents a significant commitment of resources over the next 18 to 36 months. However, we believe
developing this functionality is vitally important to our ability to compete for new business insurance 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 our 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” 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. Our target allocation is 70% of the total portfolio. Tax-exempt bonds in
2005 accounted for 58% of our portfolio compared to 52% in 2004.

In 2005, the Investment Committee of the Board of Directors of each of our insurers 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. We target those equity securities that demonstrate a history of
dividend payment and potential for capital appreciation. During 2005, we 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 our 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 State Auto 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.

In 2005, we recorded $5.6 million in net realized investment gains as compared to $7.6 million in 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 our interest income.
Equity securities were sold due to changing fundamentals, mergers or acquisitions, and changes in future
prospects for the individual companies. The proceeds from these equity sales were almost entirely reinvested into
equity securities of other companies.

We 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 we continued to hold 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. At December 31, 2005, we no longer held this particular security. The
individual circumstances involving the other-than-temporary impairments recognized in 2005 were limited to
those securities.

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. The favorable development of $44.3
million in 2005 resulted in $23.8 million of favorable development occurring in the 2004 accident year, with
smaller amounts spread out over several accident years. The following are the notable items contributing to the
2005 development:

• We hold ceded loss reserves in anticipation of transferring liabilities to a reinsurer. In 2005, ceded loss
reserves developed favorably by $14.8 million, meaning the actual ceded losses were above anticipated
levels. Historically we have had less ceded loss activity because our reinsurance retention levels are
generally high enough to exclude most claims. However, several liability claims emerged due to higher
claim frequency and severity for our umbrella, commercial auto and other liability coverages than
originally estimated. The frequency and severity assumptions for loss activity in the ceded loss layers
have been increased for future periods.

•

•

•

Catastrophe losses also developed favorably in 2005, contributing $5.8 million in reserve decreases.
Better than expected claim severity on the four Florida hurricanes from 2004 was the main reason for
the change. We initially applied a similar claim average amount to all four storms, but found later that
there were differences in claim averages between each storm.

Adjusting and other expense reserves accounted for $13.7 million of prior year reserve change. These
expense reserves have a proportional relationship to the overall claim inventory and held reserves by
accident year, as they move up or down in relation to carried loss reserves. Since reserves for both
catastrophes and non-catastrophes decreased for the prior accident years, the expense reserves declined
in a similar fashion.

The remaining favorable development is spread across several lines of business and is generally the
result of having fewer claims emerge and small claim sizes, than was anticipated in the estimates
developed as of December 31, 2004

48

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.

During the third and fourth quarters of 2005, we 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, we intend to continue to adjust our
pricing projections in order to ensure premiums keep pace with market conditions.

We monitor all lines of business, paying particular attention to personal auto (standard and nonstandard) due
to the significance this line has on our profitability and the fact that it accounts for approximately 42% of our
total earned premium. 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 our 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, we do not consider this a major deviation from the expected long
term trend for the overall line. Nonetheless, we will continue to examine the auto trends by coverage and address
any problems with appropriate pricing and underwriting action.

49

Nonstandard personal auto’s GAAP loss and LAE ratio improved 6.1 loss ratio points from the same 2004
period. We continually monitor this segment’s risk selection and rate adequacy as this line of business tends to be
more volatile in terms of loss frequency than the standard segment. Our focus on rate adequacy and monitoring
our 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 our lines of business is that 2005 is the first year that we are
earning the rate changes implemented in 2004 and 2005. We are 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 our 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.

For a further discussion regarding loss and loss expense reserves see “Other—Loss and Loss Expense

Reserves” included herein.

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.
For a further discussion of our debt activity in 2005 and 2004, see “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 our decision to continue to increase in 2005 our
holdings of tax-exempt municipal bonds as previously discussed.

LIQUIDITY AND CAPITAL RESOURCES

General

Liquidity refers to our ability to generate adequate amounts of cash to meet our needs for both long-term
and short-term cash obligations as they come due. Our 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, we continually monitor our 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.

We maintain a portion of our 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, 2006 and 2005, we had
$73.4 million and $28.7 million, respectively, in cash and cash equivalents and $1,937.9 million and $1,879.9
million, respectively, of total investments at fair value. Substantially all of our fixed maturity and equity
securities are traded on public markets. For a further discussion regarding investments see “Investments” and
“Market Risk” included herein.

50

Our insurance subsidiaries must have adequate liquidity to ensure that their cash obligations are met.
However, because the STFC Pooled Companies 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, State Auto 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, State Auto 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 State Auto Mutual and allocated to the pool member
on the basis of pool participation. As a result, we have an off-balance sheet credit–risk related to the balances due
to State Auto Mutual from insureds, agents and reinsurers, which are 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 our 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 State Auto 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 our
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 State Auto 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 $93.5 million, $226.9 million and $147.6 million for 2006,
2005 and 2004, respectively. The significant sources of operating cash flows are derived from underwriting
operations and investment income. The positive cash flows over the three year period is largely due to favorable
underwriting and investment income cash flows, offset by increases in cash paid on estimated federal income
taxes, interest expense and cash contributions to our defined benefit pension plan (the “Pension Plan”). Cash
from operations for 2006 decreased from 2005 due to our decline in net written premiums as previously
discussed along with an increase in the amount of loss and loss expenses paid from the increased level of
catastrophe losses between the two years. 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 our operating needs while providing increased opportunities for investment.
However, should our written premium decline or paid losses increase significantly our cash flows from
operations could be impacted requiring us to liquidate investments. We utilize reinsurance to limit our loss
exposure and contribute to our liquidity and capital resources. For a discussion of our reinsurance arrangements,
see “Reinsurance Arrangements” included herein.

During 2006, 2005 and 2004, as permitted by regulations of the Internal Revenue Service, we made cash
contributions of $10.0 million, $7.5 million and $5.0 million, respectively, to the Pension Plan on behalf of our
employees. The actuarially determined contribution to the Pension Plan ranges from the minimum amount we
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 we currently expect to make a cash contribution to the Pension Plan of approximately
$12.0 million during 2007. For a further discussion regarding our Pension Plan see “Employee Benefit Plans”
included herein.

Net cash used in investing activities was $43.2 million, $212.5 million and $130.4 million for 2006, 2005

and 2004, respectively. The decline in 2006 versus 2005 is principally the result of:

•

•

•

a lesser amount of cash and cash equivalents available to invest at the beginning of 2006 versus 2005
($28.7 million in 2006 compared to $64.3 million in 2005);

$54.0 million in cash available from operations in 2005 from the January 1, 2005 Pooling Arrangement
amendment; and

a current year decline in cash provided by operating activities as described above.

The increase in net investing activities in 2005 over 2004 was 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 in cash available from operations from the January 1, 2005 Pooling Arrangement
amendment; and

an increase in cash provided by operating activities.

Our financing activities for 2006 and 2005 produced a net cash outflow of $5.6 million and $50.0 million,
respectively, whereas for 2004, we had a net cash inflow of funds of $7.1 million. The following contributed to
the fluctuations between years:

•

•

•

In December 2005, we repaid a $45.5 million line of credit loan from State Auto Mutual.

In 2004, we received $3.8 million associated with our termination of two separate fair value hedge
transactions, and

Dividends paid to shareholders totaled $15.4 million, $8.6 million and $2.3 million for 2006, 2005 and
2004, respectively.

The increase in dividends between the years is due to the following:

•

•

In July 2005, State Auto Mutual’s waiver of its receipt of STFC dividends expired and was not
renewed. State Auto Mutual was paid $12.4 million and $2.4 million in dividends for 2006 and 2005,
respectively and none in 2004; and

Dividends paid per common share increased over the three year period and were: $0.38 in 2006; $0.27
in 2005 and $0.17 in 2004.

On March 2, 2007, the Board of Directors of State Auto Financial declared a quarterly cash dividend of
$0.10 per common share, payable on March 30, 2007, to stockholders of record on March 16, 2007. This is the
63rd consecutive quarterly cash dividend declared by State Auto Financial’s Board since we had our initial public
offering of common stock on June 28, 1991. We have increased cash dividends to stockholders for fourteen
consecutive years.

Borrowing Arrangements

The following provides an overview of our borrowing arrangements during 2006 and outstanding at

December 31, 2006:

Credit Agreement

We have a Credit Agreement (the “Credit Agreement”) with a syndicate of lenders which provides for a
$100.0 million five-year unsecured revolving credit facility (the “Credit Facility”). During the term of the Credit
Facility, we have 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 catastrophe loss

52

purposes. However, we currently intend to keep the facility available in the event there is a need to fund losses
under the catastrophe reinsurance program with State Auto P&C. For a discussion of our catastrophe reinsurance
arrangements, see the “Reinsurance Arrangements” section included herein. 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 us 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. We have not borrowed any funds
under the Credit Agreement. As of December 31, 2006, we were in compliance with all of the covenants under
the Credit Agreement.

Senior Notes

In 2003, we issued $100.0 million of unsecured Senior Notes due November 2013. The Senior Notes bear
interest at a fixed rate of 6.25% per annum, which is payable each 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 our subsidiaries
and thereby are effectively subordinated to all our subsidiaries’ existing and future indebtedness. As of
December 31, 2006, we were in compliance with all covenants related to the Senior Notes.

Trust Securities

In 2003, our Delaware business trust subsidiary (the “Capital Trust”) issued $15.0 million liquidation
amount of capital securities due in 2033. In connection with the Capital Trust’s issuance of the capital securities
and the related purchase by us of all of the Capital Trust’s common securities (liquidation amount of $0.5
million), we have 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 January 2004 through December 31, 2006
ranged from 5.37% to 9.60%.

Notes Payable Summary

At December 31, 2006, our notes payable are summarized as follows:

Related to our notes payable, our primary market risk exposure is to the change in interest rates and our
credit rating. For a discussion regarding our credit ratings see “Credit and Financial Strength Ratings” included
herein. Based upon the notes payable carrying value at December 31, 2006, we had $15.5 million notes payable
with variable interest and $102.9 million notes payable with interest fixed at 6.25%, which equated to
approximately 13.1% variable interest debt and 86.9% fixed interest debt. Our 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) our
currently existing notes payable fixed and variable interest rate position.

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.

For the first two quarters of 2006, there were no material changes in our reinsurance arrangements from
those in place as of December 31, 2005. However, as of July 1, 2006 we made revisions to our casualty excess of
loss, property per risk excess of loss, and property catastrophe excess of loss reinsurance programs through
treaties arranged through a reinsurance intermediary with several reinsurers.

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. Coverage under the casualty excess of loss program was
expanded as of July 1, 2006, so that reinsurers became responsible for 95% of a covered loss in excess of $2.0
million, up to $5.0 million of covered loss, compared to 90% under the previous program. 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 $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 property per risk excess of loss program was revised as of July 1, 2006, so that each company within
the our State Auto Group became responsible for the first $3.0 million of each covered loss, compared to the first
$2.0 million of each covered loss under the previous program. The previous retention of $2.0 million had been in
place for nine years. The State Auto Group’s capacity to retain more direct exposure has grown over that time,
and raising the retention under this program tempered the effect of higher property reinsurance rates in 2006.
Also as of July 1, 2006, coverage was expanded so that reinsurers became responsible for 100% of the excess
over the retention up to $20.0 million of covered losses, compared to up to $10.0 million of covered loss
previously. Increasing the amount of reinsurance limits purchased under this program allowed the State Auto
Group to reduce the amount of facultative reinsurance purchased for property limits between $10.0 million and
$20.0 million, resulting in a cost savings. The rates for this reinsurance are negotiated annually.

The property catastrophe excess of loss program was revised as of July 1, 2006, so that the State Auto Group
began to retain the first $55.0 million of catastrophe loss per occurrence, compared to the first $40.0 million of
catastrophe loss per occurrence under the previous program. The previous retention of $40.0 million had been in
place for 10 years. The State Auto Group’s capacity to retain more direct exposure has grown over that time, and
raising the retention under this program tempered the effect of higher property reinsurance rates in 2006. The
amount of reinsurance coverage did not change at July 1, 2006. Excess of the $55.0 million retention, this program
which provides traditional catastrophe reinsurance coverage continues to provide coverage for the next $80.0
million of covered loss with a 5% co-participation. The rates for this reinsurance are negotiated annually.

We also participate in an intercompany catastrophe reinsurance agreement by which State Auto P&C acts as
the catastrophe reinsurer for the State Auto Group. This agreement was revised as of July 1, 2006, so that the
coverage attaches at $135.0 million of catastrophe loss per occurrence, compared to the first $120.0 million of
catastrophe loss per occurrence under the previous program. This change is a direct result of the change in
retention under the property catastrophe excess of loss program discussed in the previous paragraph. The amount
of reinsurance coverage did not change at July 1, 2006. Excess of the $135.0 million retention, this program
continues to provide coverage for the next $100.0 million of covered loss. There have been no losses assumed
under this agreement.

54

In addition to the treaties described above, the State Auto Group is also party to treaties for workers’
compensation excess of loss and workers’ compensation catastrophe excess of loss. These treaties were renewed
July 1, 2006 with no material revisions. 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.

The workers’ compensation catastrophe excess of loss treaty 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.

The State Auto Group has also 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.

Regulatory Considerations

At December 31, 2006, 2005 and 2004, each of our 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 our 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 our insurance companies’ operating performance on a statutory
accounting basis (each of our insurance subsidiaries operates within the defined range for the other measures),
the net written premium to statutory surplus ratio (the “leverage ratio”) is monitored to ensure that each of our
insurance subsidiaries continue 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 our insurance subsidiaries at December 31, 2006, 2005 and 2004 were as

follows:

Our insurance subsidiaries pay dividends to State Auto Financial which in turn may be used by State Auto
Financial to pay dividends to stockholders or to make principal and interest payments on debt. Individual states
limit the amount of dividends that our insurance subsidiaries domiciled in those states can pay without prior
approval. The maximum amount of dividends that may be paid to State Auto Financial during 2007 by its
insurance subsidiaries without prior approval under current law is limited to $140.8 million, adjusted for
dividends paid by the insurance subsidiaries in the previous twelve months. State Auto Financial received no

56

dividends from its insurance subsidiaries in 2006 and $40.5 million and $12.0 million in 2005 and 2004,
respectively. We are required to notify the insurance subsidiaries’ applicable state insurance commissioner within
five business days after declaration of all such dividends and at least ten days prior to payment. Additionally, the
domiciliary state commissioner of each insurance 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 meet 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, 2006, the ratio of
total adjusted statutory capital to authorized control level of State Auto Financial’s insurance subsidiaries ranged
from 912% to 1,679%.

We are reviewed regularly by the independent rating agencies listed in the table above. Ratings provide a
meaningful way for policyholders, agents, creditors and stockholders to compare us to our competitors. The
published credit ratings on 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 our 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. State Auto 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 and the Mutual Pooled Companies are
collectively assigned a pool rating by A.M. Best while SA National is rated by A. M. Best as a part of the total
group.

Our 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, 2006, our
A.M. Best and Moody’s ratings were assigned stable outlooks while the Standard and Poor’s ratings were
assigned positive outlooks.

Overview

Stateco performs investment management services on our behalf and that of State Auto Mutual and its
subsidiaries. The Investment Committee of the Board of Directors of each of our insurers sets investment policies
to be followed by Stateco.

Our primary investment objectives are to generate income, preserve capital and maintain adequate liquidity
for the payment of claims. Our current investment strategy does not rely on the use of derivative financial
instruments. Our investment policy and guidelines permit investment in debt issues rated A or better by two
major rating services. Our fixed maturities portfolio is composed of high quality, investment grade issues,
comprised almost entirely of debt issues rated AAA or AA. We do not hold any mortgage loans.

We manage our 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. We invest only in stocks that currently pay a dividend. As of December 31, 2006, our equity
portfolio consisted of approximately 100 different stocks. The largest single position was 2.8% of the equity
portfolio based on fair value and the top ten positions were equal to approximately 20% of the equity portfolio.
The chart below shows the industry sector breakdown of our equity portfolio versus the S&P 500 Index based on
fair value as of December 31, 2006.

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

At December 31, 2006 and 2005, 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, specifically within “accumulated
other comprehensive (loss) income” and as such are not included in the determination of net income.

We regularly monitor our 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 our intent and ability to
hold securities until recovery. When a security in our investment portfolio has been determined to have a decline
in fair value that is other-than-temporary, we adjust 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.

Other than the impairment write downs previously discussed, a review of our investments at December 31,
2006 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,
2006, 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, 2006.

and losses, adjusted for investments with other-than-temporary impairment at December 31, 2006:

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.

In 2005 and part of 2006, we participated in a securities lending program whereby certain fixed maturity and
equity securities from our investment portfolio were loaned to other institutions for short periods of time. We
required collateral, equal to 102% of the market value of the loaned securities. The collateral was invested by the
lending agent, in accordance with our guidelines, generating investment income, net of applicable fees. We
accounted for this program as a secured borrowing and recorded the collateral held and corresponding liability to
return the collateral on our balance sheet. During the second quarter of 2006, we terminated our participation in
this program and there were no securities on loan or related collateral held as of September 30, 2006. At
December 31, 2005, the amount of collateral held was approximately $99.0 million and the amount of securities
lent was $96.0 million.

Market Risk

At December 31, 2006, total investments at fair value comprise approximately 86% of our total assets. Of
our total investments, 85.0% were invested in fixed maturities, 14.7% in equity securities, and 0.3% in other
invested assets. Cash and cash equivalents represented approximately 3.3% of our total assets at December 31,
2006.

Our 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) our liquidity requirements at any given time; and (f) our current federal income tax position and relative
spread between after tax yields on tax-exempt and taxable fixed income investments.

Our 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. Our fixed income securities are subject to interest
rate risk whereby the value of the securities varies as market interest rates change. We manage this risk by
closely monitoring the duration of the fixed income portfolio. The duration of the fixed maturity portfolio was
approximately 5.35 and 5.14 as of December 31, 2006 and 2005, respectively. The table below summarizes our
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, 2006:

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 our liabilities and possibly other financial assets.
We caution 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 us 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.

We believe 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. We do not intend to change our
investment policy on the quality of our 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. We also manage 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. We do not rely on the use of derivative financial instruments. To provide
us greater flexibility in order to manage our market risk exposures, we categorize our fixed maturities as
available-for-sale. We do not maintain a trading portfolio.

As of December 31, 2006, our equity portfolio had a beta of 1.00 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 us 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 we
hope to limit liquidity risk in the equity portfolio. The equity portfolio does not have any direct exposure to
exchange rate risk since we do not hold any foreign stocks. We constantly monitor the equity portfolio holdings
for any credit risk issues that may arise. We do not invest in any commodity futures or commodity oriented
mutual funds.

Some parameters have been set by the Investment Committee of the Board of Directors of each of our
insurers 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 Board of Directors of each of our insurers. 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
in timely special situations. Equity
portfolio may deviate from these requirements allowing us to invest
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, 2006, is presented in tabular form above.

Our total

investments, at fair value, grew approximately 3.1% during 2006 to $1,937.9 million at
December 31, 2006, from $1,879.9 million at December 31, 2005. This growth was generated primarily from net
cash flows provided by operations, along with an increase of $19.1 million in the cumulative net unrealized gains
on investments. The net unrealized gain on our equity portfolio increased $22.6 million to $53.4 million at
December 31, 2006, while our net unrealized gains on our fixed maturity portfolio declined $3.2 million to $16.8
million at December 31, 2006. Cumulative unrealized gains related to other invested assets decreased $0.3
million to $0.5 million at December 31, 2006.

Employee Benefit Plans

The State Auto Group has a defined benefit pension plan (“Pension Plan”) and a postretirement health care
plan covering substantially all employees (collectively “the benefit plans”). Several factors, which attempt to
anticipate future events, are used in calculating the expense and liability related to the benefit plans. Key factors
include assumptions about the expected rates of return on plan assets, discount rates, and health care cost trend
rates. We consider market conditions, including changes in investment returns and interest rates, in making these
assumptions. We use a measurement date of September 30 as currently permitted under SFAS No. 87
“Employers’ Accounting for Pensions” (“SFAS 87”) and SFAS No. 106 “Employers’ Accounting for
Postretirement Benefits Other than Pensions” (“SFAS 106”) when determining our liabilities at December 31.

To calculate the State Auto Group’s December 31, 2006 pension projected benefit obligation (“PBO”) we
used a discount rate of 6.0% based on an evaluation of the expected future benefit cash flows of the Pension Plan
used in conjunction with the Citigroup Pension Discount Curve at the measurement date. A lower discount rate
results in, all else equal, a higher present value of the benefit obligation. We selected an expected long-term rate
of return on our plan assets of 9.0% by considering the mix of investments and stability of investment portfolio
along with actual investment experience during the lifetime of the plan. To calculate the net periodic benefit cost
for the year ended December 31, 2006, a discount rate of 5.75% and an expected long-term rate of return on plan
assets of 9.0% were used.

The selected discount rate of 6.0% increased 0.25 points from the 5.75% rate used in 2005 which had the
effect of decreasing the 2006 PBO and related unrecognized net actuarial loss by approximately $7.8 million.
Cumulative unrecognized actuarial losses of approximately $77.4 million, which are now being recognized on
our balance sheet pursuant to SFAS 158 (defined below), are being systematically recognized as an increase in
net periodic cost 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.

The accumulated benefit obligation (“ABO”) of a defined benefit plan represents the actuarial present value
of benefits attributed by the pension benefit formula to employee service rendered prior to the measurement date
and based on current and past compensation levels, while the PBO is the ABO plus a factor for future
compensation levels. At December 31, 2006, the ABO and PBO were $190.9 million and $213.4 million,
respectively. The amount of PBO was reflected on our balance sheet at December 31, 2006 with our adoption of
the first phase of SFAS 158 (defined below) as measured against the Pension Plan assets. At December 31, 2006
the fair value of the Pension Plan assets was $197.3 million, which resulted in an underfunding status within our
balance sheet of $16.1 million. The State Auto Group has consistently targeted contributions to the Pension Plan
with the objective of maintaining a fully funded status on an ABO basis. Historically our plan assets have
exceeded our ABO. The ABO, which considers current compensations level only, provides information about the
obligation an employer would have if the plan were discontinued at the date of measurement date. This funding
objective has served our plan participants well knowing that we were fully funded on a current basis as well as
the fact that we have not had to recognize in 2006 or anytime prior an additional minimum liability as would
have been previously required under SFAS 87.

62

Key assumptions used in determining the amount of the benefit obligation and related periodic cost
recognized for postretirement benefits other than pensions under SFAS 106 include the discount rate and the
assumed health care cost trend rate. To calculate the State Auto Group’s 2006 benefit obligation for our health
care plan, we increased our selected discount rate by 0.25 points to 6.00% from the 2005 discount rate to match
the anticipated stream of future benefit payments. This change in the discount rate had the effect of decreasing
the benefit obligation and related unrecognized net actuarial loss by $4.9 million. We assume 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. For 2006 the expected rate of
increase in future health care costs was 10% for 2007, 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, our benefit
obligation for 2006 would have increased by $24.3 million and decreased by $19.4 million, respectively. The
benefit obligation under our health care plan was $122.7 million at December 31, 2006 which exceeded the fair
value of plan assets of $2.2 million, resulting in an underfunding status of $120.5 million in our balance sheet.

In September 2006, the FASB issued SFAS No. 158, “Employers’ Accounting for Defined Benefit Pension
and Other Postretirement Plans, an amendment of FASB Statements No. 87, 88, 106, and 132(R)” (“SFAS 158”)
which requires employers with defined benefit pension and other postretirement benefit plans, such as health
care, to recognize the funded status of its benefit plans on its balance sheet and measure the fair value of plan
assets and benefit obligations as of the date of the fiscal year-end balance sheet date thereby eliminating the use
of an earlier measurement date and to provide additional disclosures. The new measurement date requirement is
not effective until fiscal years ended after December 15, 2008. Adopting SFAS 158 required us to recognize the
funded status (i.e. the difference between the fair value of plan assets and the benefit obligations) on our balance
sheet, with a corresponding adjustment to accumulated other comprehensive income, net of tax. The adoption of
SFAS 158 at December 31, 2006 had the impact of decreasing accumulated comprehensive income by $63.9
million, net of tax, which was represented by the following:

•

•

For our Pension Plan: net unrecognized actuarial losses of $77.4 million ($50.3 million net of tax);
unrecognized prior service costs of $3.4 million ($2.2 million net of tax); unrecognized transition asset
remaining from the initial adoption of SFAS 87 of $3.0 million ($1.9 million net of tax), all of which
were previously netted against the plan’s funded status on our balance sheet pursuant to the provisions
of SFAS 87. These amounts will be subsequently recognized as a component of our net periodic cost
(benefit) pursuant to our historical accounting policy for amortizing and allocating such amounts. The
amount of amortization expected to be recognized during the fiscal year ending December 31, 2007 for
the State Auto Group is $3.9 million ($2.5 million net of tax), $0.5 million ($0.3 million net of tax),
and a benefit of $0.6 million ($0.4 million net of tax), respectively.

For our postretirement health care plan: net unrecognized actuarial losses of $23.6 million ($15.3
million net of tax); unrecognized prior service costs of $3.2 million ($2.1 million net of tax), all of
which were previously netted against the plan’s funded status in our balance sheet pursuant to the
provisions of SFAS 106. These amounts will be subsequently recognized as a component of our net
periodic cost (benefit) pursuant to our historical accounting policy for amortizing and allocating such
amounts. The amount of amortization expected to be recognized during the fiscal year ending
December 31, 2007 for the State Auto Group is $0.8 million ($0.5 million net of tax) and $0.5 million
($0.3 million net of tax), respectively.

With regard to the adoption of the new measurement guidelines, we are continuing to review the transition

alternatives available to us. The adoption of SFAS 158 did not have an impact on our debt covenants.

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. We and our 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. We determined that the enactment of the Act was not a significant event and
incorporated the effect of the Act in the 2005 measurement date pursuant to FSP 106-2.

The actuarial assumptions used by us in determining 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 we believe that the assumptions used are appropriate, differences in
actual experience or changes in assumptions may materially affect our financial position or results of operations.

Loss and Loss Expense Reserves

Our loss and loss expense reserves include the accumulation of unpaid individual case estimates for claims
that have been reported and estimates of claims that have been incurred but not reported (“IBNR”) as well as
estimates of the expenses associated with processing and settling all reported and unreported claims. Our loss and
loss expense reserves are not discounted to present value.

Losses and allocated loss expense reserves (“Loss and ALAE Reserve”) are management’s best estimates
(“MBE”) at a given point in time of what we expect 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 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 data for similar
claims with provision for trend changes caused by inflation. 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

64

reserves. Generally, reported losses initially reserved on a formula basis and not settled after six months are case
reserved at that time. The process for calculating the IBNR component of the Loss and ALAE Reserve is to
develop an estimate of the ultimate losses and allocated loss expenses incurred, and then subtract all amounts
already paid and held in case and formula reserves.

The ultimate determination of MBE integrates information and analysis provided by several disciplines
within our Company, including claims, actuarial and accounting. This assessment requires considerable judgment
in understanding how claims mature, which lines of business are the most volatile, and how trends change over
time. Loss and ALAE Reserves represent an estimate at a given point in time based on many variables including
historical and statistical
legal developments, storm loss estimates, and economic
conditions. Although we consider many different sources of information, as well as a number of actuarial
methodologies to estimate our Loss and ALAE Reserve, there is no single method for determining the exact
ultimate liability.

information,

inflation,

Our internal actuarial staff conducts quarterly reviews of projected loss development information to assist
management in making estimates of ultimate losses and loss expenses. 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 many of the assumptions underlying each reserving methodology, such as
claim frequency, claim severity and loss ratios. Nonetheless, changes, which are not contemplated, do occur over
time, and those changes are incorporated in subsequent valuations of the loss reserves.

We use a number of different methodologies to estimate the IBNR component of the Loss and ALAE
Reserves. Our reserves include amounts related to short tail and long tail lines of business. “Tail” refers to the
time period between the occurrence of a loss and the settlement of the claim. The longer the time span between
the incidence of a loss and the settlement of the claim, the more the ultimate settlement amount can vary. The
reserving methods and strengths and weaknesses of each are described below.

Short-Tail Business: For short-tailed contracts, the claims are typically settled within five years, and the
most common actuarial estimates are based on techniques using link ratio projections of incurred losses, paid
losses, claim counts and claim severities. Each of these methods is described below in detail. Separate
projections are made for catastrophes that are in the very early stages of development based on specific
information known through the reporting date.

Incurred Loss Development Method: The Incurred Loss Development Method is probably the most
common actuarial method used in projecting indicated IBNR reserves. This method uses paid loss experience as
well as the outstanding estimates (average & case reserves) for claims that have been reported and are still open.
The underlying assumption of the Incurred Loss Development Method is that case reserve adequacy remains
consistent over time. This method’s advantage is its responsiveness to changes in reported losses, which is
particularly valuable in the less mature accident years. The disadvantage of the Incurred Loss Development
Method is that case reserve adequacy changes will distort the IBNR projections.

Paid Loss Development Method: The Paid Loss Development Methods use calculations that are very
similar to the Incurred Loss Development Method. The key difference is that the data used in paid methods
excludes the case reserve estimates, so only paid losses are utilized. With these methods, a payment pattern is
estimated to project ultimate settlement values for each accident year, with the underlying assumption that claims
are settled at a consistent rate over time. Neither case reserves nor the rate at which claims are reported (except to
the extent that the reporting pattern might influence the payment pattern) is relevant to the results of this method.
This method’s advantage is the estimates of ultimate loss are independent of case reserve adequacy and are
unaffected by company changes in case reserving philosophy. The disadvantages are that the paid method does
not use all of the available information, and in some cases the liability payment patterns require the application of
very large development factors to relatively small payments in the immature years.

65

Claim Counts and Severities Methods: The Counts and Severities Method calculations are very similar to
the other methods. The incurred claim counts reported to date are projected to an ultimate value. Similarly, the
incurred loss severities are projected to ultimate. The ultimate incurred count is multiplied by the ultimate
incurred severity, for each accident year, to arrive at the ultimate incurred loss. Finally, as with the other loss
development methods, an estimate of the IBNR reserve is calculated by subtracting the reported losses from the
estimated ultimate losses.

Long-Tail Business: Reserve estimates for long-tailed contracts use the same methods listed above for
short-tailed lines, along with several other methods as determined by the actuary. For example, premium-based
methods may be used in developing ultimate loss estimates, including the Expected Loss Ratio, Bornhuetter-
Ferguson, and Least-Squares techniques as described below. We also use statistical models when the historical
patterns can be reasonably approximated.

Expected Loss Ratio Method: The Expected Loss Ratio Method generates indicated IBNR by multiplying
an expected loss ratio by earned premium, then subtracting incurred-to-date losses. For slower reporting lines of
business, new products, or data that is very immature, the actual claim data is often too thin for traditional
projections. With this method the premiums are used as a measure of loss exposure, and the loss ratios can be
derived from pricing expectations.

Bornhuetter-Ferguson Method: The Bornhuetter-Ferguson Method is a weighted average of the Expected
Loss Ratio Method and the Incurred Loss Development Method, using the percentage of losses reported as the
weight. This method is particularly useful where there is a low volume of data in the current accident period, or
where the experience is volatile. In general this method produces estimates that are very similar to the Incurred
Loss Development Method.

Least Square Loss Development Method: In the Least Squares Loss Development Method the statistical
technique of least squares regression is applied to a triangle of reported loss ratios to project the ultimate loss
ratio in each accident year. Using historical loss ratios puts the data for each time period on a more consistent
exposure basis, because premium levels generally correlate well with insured exposures. A by-product of the
regression function is an estimate of credibility for each stage of development. In cases where the regression
parameters fall outside of a reasonable range, the projection defaults to the incurred loss method.

Selection Process: In determining which reserving method to use for a particular line of business or
accident year, diagnostic tests of loss ratios and severity trends are considered, as well as the historic case reserve
adequacy and claim settlement rate. In general the Incurred Loss Development Method is used if the projections
are stable, the data is credible, historic case reserve adequacy is consistent, and the loss ratios and loss severities
are reasonable. Other reserving methods are considered as well for particular lines of business or accident years,
given supplementary information like open claim counts and prior period development. For example, if more
than one method provides a reasonable projection, the actuary may select an average of those methods. There is
considerable judgment applied in the analysis of the historical patterns and in applying business knowledge that
reflects our underwriting and claims risk.

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. The primary determinant in estimating the reserve range boundaries are the variances measured
within the historical reserving data for lines of business. Property lines typically have smaller variances, while
liability lines can experience significant variability. MBE of loss reserves considers the actuarial point estimate
and expected variation to establish an appropriate position within a range. MBE for SA National and the STFC
Pooled Companies’ share of the Pooled Companies’ Loss and ALAE Reserves at December 31, 2006 is $709.5
million, compared with an actuarial point estimate of $688.3 million that is within a projected range of $652.4
million to $726.1 million. (These values presented are on a direct basis, gross of salvage and subrogation

66

recoverable, and before reinsurance, except for the STFC Pooled Companies’ participation in the inter-company
Pooling Arrangement. Therefore, these values cannot be compared to other loss and loss expenses payable tables
included elsewhere within this Form 10-K.)

The potential impact of the 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 $726.1 million, the
reserve increase of $16.6 million is an after-tax decrease of $10.8 million on net income. Likewise, should losses
decline to the low end of $652.4 million, the $57.1 million reserve decrease would add $37.1 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, 2006, other liability Loss and ALAE Reserve 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 10% 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 10% 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
$56.1 million on reserves, or a $36.4 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.

In addition to establishing Loss and ALAE Reserves, as described above, we establish reserves 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. Consequently, this component of the loss
expense reserve has a proportional relationship to the overall claim inventory and held reserves by accident year,
as they move up or down in sync with carried 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 and
also assumes that the underlying claims process and mix of business do not change drastically over time.

Net losses and loss expenses payable at December 31, 2006 decreased $50.3 million (7.1%) from 2005 due

to a combination of the following:

•

•

•

•

Declining exposure base throughout 2006 on many lines of business, as previously discussed;

Improved claim severity trends, primarily on the liability lines, also previously discussed;

At the end of 2005, losses, primarily on the property lines, related to Hurricane Katrina remained in
reserve status due to the unprecedented conditions making the logistics of adjusting and settling claims
difficult;

Hurricane Wilma, which occurred in the fourth quarter of 2005, also accounted for outstanding
reserves at the end of 2005 in the same property lines as reserves relating to Hurricane Katrina.

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 $3.3 million, and
environmental reserves are $6.6 million, for a total of $9.9 million, or 1.5% of net losses and loss expenses
payable. Our environmental reserves increased approximately $1.0 million from 2005 primarily from the state of
Indiana where there was an adverse court ruling several years ago. Because we have insured primarily product
retailers and distributors, we do not expect to incur the same level of liability as companies that have insured
manufacturing risks.

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. Our
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. See additional discussion relating to
Losses and Loss Expense Reserves at Impact of Significant External Factors, included herein.

New Accounting Standards

For a discussion regarding our adoption of SFAS 158 at December 31, 2006 see “Employee Benefits Plans”

included herein.

Adoption of Recent Accounting Pronouncements

In September 2006, the FASB issued SFAS No. 158, “Employers’ Accounting for Defined Benefit Pension
and Other Postretirement Plans, an amendment of FASB Statements No. 87, 88, 106, and 132(R)” (“SFAS 158”)

69

which requires employers of defined benefit pension and postretirement benefit plans other than pensions
(collectively “benefit plans”) to recognize the funded status of their benefit plans in their balance sheet, measure
the fair value of plan assets and benefit obligations as of the date of the fiscal year-end balance sheet date thereby
eliminating the use of an earlier measurement date and provide additional disclosures. The new measurement
date requirement is not effective until fiscal years ended after December 15, 2008. On December 31, 2006, we
adopted the recognition and disclosure provisions of SFAS 158. The adoption of SFAS 158 had no effect on our
consolidated statement of income for year ended December 31, 2006, or for any prior period presented, and it
will not affect our operating results in future periods. Adopting SFAS 158 required us to recognize the funded
status (i.e. the difference between the fair value of plan assets and the benefit obligations) of our benefit plans in
the December 31, 2006 balance sheet, with a corresponding adjustment to accumulated other comprehensive
income, net of tax. The $63.9 million adjustment to accumulated other comprehensive income at adoption
represents the following:

•

•

For the defined benefit pension plan: net unrecognized actuarial losses of $77.4 million ($50.3 million
net of tax); unrecognized prior service costs of $3.4 million ($2.2 million net of tax); unrecognized
transition asset remaining from the initial adoption of SFAS 87 of $3.0 million ($1.9 million net of
tax), all of which were previously netted against the plan’s funded status in our balance sheet pursuant
to the provisions of SFAS 87. These amounts will be subsequently recognized as a component of our
net periodic pension cost (benefit) pursuant to our historical accounting policy for amortizing and
allocating such amounts. The amount expected to be recognized during the fiscal year ending
December 31, 2007 for the State Auto Group is $3.9 million ($2.5 million net of tax), $0.5 million
($0.3 million net of tax), and a benefit of $0.6 million ($0.4 million net of tax), respectively.

For the postretirement benefit plan other than pensions: net unrecognized actuarial losses of $23.6
million ($15.3 million net of tax); unrecognized prior service costs of $3.2 million ($2.1 million net of
tax), all of which were previously netted against the plan’s funded status in our balance sheet pursuant
to the provisions of SFAS 106. These amounts will be subsequently recognized as a component of our
net periodic pension cost (benefit) pursuant to our historical accounting policy for amortizing and
allocating such amounts. The amount expected to be recognized during the fiscal year ending
December 31, 2007 for the State Auto Group is $0.8 million ($0.5 million net of tax) and $0.5 million
($0.3 million net of tax), respectively.

At December 31, 2006, we continued to use the earlier measurement date of September 30, 2006, and are
currently reviewing the transition alternatives available. The adoption did not have an impact on our debt
covenants.

In December 2004, the FASB issued SFAS 123(R) which supersedes APB Opinion No. 25, “Accounting for
Stock Issued to Employees” (“APB 25”), and amends SFAS No. 95, “Statement of Cash Flows.” SFAS 123(R)
requires all share-based payments to employees, including grants of employee stock options, to be recognized as
expense based on their fair values. Pro forma disclosure is no longer an alternative. We adopted SFAS 123(R) on
January 1, 2006, using the modified prospective method and, accordingly, the financial statements for prior
periods do not reflect any restated amounts. In accordance with SFAS 123(R), we are required to record
compensation expense for all awards granted after the date of adoption and for the unvested portion or previously
granted awards that remain outstanding at the date of adoption. As a result of adopting SFAS 123(R) on
January 1, 2006, our income before income taxes and net income for the year ended December 31, 2006 are $6.6
million and $4.9 million lower, respectively, than if we had continued to account for share-based payments under
APB 25. Basic and diluted earnings per share for the year ended December 31, 2006 are $0.12 and $0.12 lower,
respectively, than if we had continued to account for share-based compensation under APB 25.

Pending Adoption of Accounting Pronouncements

In September 2006, the FASB issued FASB Statement 157, “Fair Value Measurements” (“SFAS 157”),
which is to be effective for fiscal years beginning after November 15, 2007, and interim periods within those
fiscal years. SFAS 157 establishes a single authoritative definition of fair value, sets out a framework for

70

measuring fair value, and requires additional disclosures about fair-value measurements. The statement imposes
no requirements for additional fair-value measures in financial statements. We are currently assessing the impact
of this new guidance, but do not believe it will be material. We plan to adopt this guidance effective January 1,
2008.

In June 2006, the FASB issued FASB Interpretation No. 48, “Accounting for Uncertainty in Income Taxes”
(“FIN 48”), which is to be effective for fiscal years beginning after December 15, 2006. FIN 48 clarifies the
accounting for income taxes by prescribing the minimum recognition threshold a tax position is required to meet
before being recognized in the financial statements. FIN 48 also provides guidance on derecognition,
measurement, classification, interest and penalties, accounting in interim periods, disclosure and transition. We
are currently assessing the impact of this new guidance, but do not believe it will be material. We plan to adopt
this new guidance effective January 1, 2007.

In February 2006, the FASB issued FASB Statement 155, “Accounting for Certain Hybrid Financial
Instruments—an amendment of FASB Statements No. 133 and 140” (“SFAS 155”), which is to be effective for
all financial instruments acquired or issued after the beginning of an entity’s fiscal year that begins after
September 15, 2006. SFAS 155 permits fair value re-measurement for any hybrid financial instruments that
contain an embedded derivative that would otherwise require bifurcation, clarifies which interest only strips and
principal-only strips are not subject to the requirements of Statement 133, establishes a requirement to evaluate
interests in securitized financial assets in order to identify interests that are freestanding derivatives or that are
hybrid financial
instruments that contain an embedded derivative requiring bifurcation, clarifies that
concentrations of credit risk in the form of subordination are not embedded derivatives, and amends Statement
140 to eliminate the prohibition on a qualifying special-purpose entity from holding a derivative financial
instrument that pertains to a beneficial interest other than another derivative financial instrument. We have
assessed the impact of this new guidance, and it will not be material. We plan to adopt this guidance effective
January 1, 2007.

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. SOP 05-1 provides guidance on accounting for deferred acquisition costs associated with
modifications to or the internal replacement of insurance contracts. SOP 05-1 focuses on modifications to
contracts with integrated product features and internal replacement of contracts in which the new contract offers
product features not included in the old contract when both were priced together. Our insurance contracts include
only nonintegrated contract features as defined in SOP 05-1, which are contract features that provide coverage
that
in
incremental
re-underwriting or re-pricing 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 by us, the impact of SOP 05-1 upon implementation will not be material. We plan to adopt this guidance
effective January 1, 2007.

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, we attempt to
anticipate increases from inflation subject to the limitations of modeling economic variables. General inflation,
as measured by the Consumer Price Index, 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, 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. We continue to adjust our pricing projections as loss cost trends change in
order to ensure premiums keep pace with inflation in all lines of business.

71

We consider 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.

In “Loss and Loss Expenses Reserves,” we include a discussion 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 approximately 50% of our total reserves, perhaps the most significant external variable is legal
developments. Court decisions, as discussed below, have had significant impact on the property and casualty
insurance industry. Some of these decisions have a more prospective effect, for example, when contract
provisions relating to third party coverages are construed in ways not anticipated by us. 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 we do business. If a court
construes a UM statute adversely to us and the industry, the decision typically has a retroactive effect with the
court’s interpretation being applied as if the UM statute has always been interpreted that way. This retroactive
application 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 restored by an adverse court decision. We
consider the impact of adverse court decisions of which we have become aware when we set ultimate loss and
loss expense 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 our 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 us to some retroactive liabilities. These liabilities are
sought to be addressed by the ultimate loss and loss expense reserve that is our estimate of loss and loss expenses
payable.

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

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. Our 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. We may also be adversely affected by regulatory actions on matters within the jurisdiction of the various
insurance departments where we do business or have entities domiciled.

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, 2006 and 2005, and the related consolidated statements of income, stockholders’
equity and cash flows for each of the three years in the period ended December 31, 2006. 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, 2006 and
2005, and the consolidated results of their operations and their cash flows for each of the three years in the period
ended December 31, 2006, in conformity with U.S. generally accepted accounting principles. Also, in our
opinion, the related financial statement schedules, when considered in relation to the basic financial statements
taken as a whole, present fairly in all material respects the information set forth therein.

As discussed in Note 1 to the consolidated financial statements, the Company changed its method of
accounting for share-based compensation expense as of January 1, 2006,
to adopt Financial Accounting
Standards Board Statement No. 123(R), “Share-Based Payment.” As discussed in Note 9 to the consolidated
financial statements, the Company also changed its method of accounting for defined benefit pension and other
postretirement plans as of December 31, 2006, to adopt Financial Accounting Standards Board Statement
No. 158, “Employers’ Accounting for Defined Benefit Pension and Other Postretirement Plans.”

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, 2006, 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 2, 2007
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, 2006, 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, 2006, 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, 2006, 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, 2006
and 2005, and the related consolidated statements of income, stockholders’ equity and cash flows for each of the
three years in the period ended December 31, 2006 of State Auto Financial Corporation and our report dated
March 2, 2007 expressed an unqualified opinion thereon.

and its wholly-owned subsidiaries:

•

State Auto Property and Casualty Insurance Company (“State Auto P&C”), an Iowa corporation

• Milbank Insurance Company (“Milbank”), a South Dakota corporation

•

•

•

•

•

Farmers Casualty Insurance Company (“Farmers”), an Iowa corporation

State Auto Insurance Company of Ohio (“SA Ohio”), an Ohio corporation

State Auto National Insurance Company (“SA National”), an Ohio corporation

Stateco Financial Services, Inc. (“Stateco”), an Ohio corporation

The financial statements include the operations and financial position of 518 Property Management and

Leasing, LLC (“518 PML”), whose members are State Auto P&C and Stateco.

State Auto Financial, an Ohio corporation, is a majority-owned subsidiary of State Automobile Mutual
Insurance Company (“State Auto Mutual”), an Ohio corporation. State Auto Financial and subsidiaries are
referred to herein as the “Companies” or the “Company.” All significant intercompany balances and transactions
have been eliminated in consolidation.

b. Description of Business

The Company, through State Auto P&C, Milbank, Farmers and SA Ohio, provides standard personal and
business insurance to its policyholders. The Company’s principal lines of insurance 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 property and casualty insurers. 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 State Auto Mutual and its affiliates. The nature of the underlying policies and
geographical distribution of State Auto Mutual’s and its affiliates’ 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.

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

Notes to Consolidated Financial Statements, Continued

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

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 periods 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
to
formulate estimates of the ultimate cost
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 statement of cash flows have been reclassified to conform to

the 2006 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 a part of “accumulated other comprehensive (loss) income” and,
as such, are not included in the determination of net income. Realized gains and losses on the sales 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 years 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 $20.5 million and $28.3
million at December 31, 2006 and 2005, 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. Premiums

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. See New Accounting
Standards regarding the Company’s adoption of SFAS No. 158 (defined below) at December 31, 2006.

k. Share-Based Compensation

See Note 1I—New Accounting Standards regarding the Company’s adoption of SFAS No. 123 (revised
2004), “Share-Based Payment” (SFAS 123(R)) on January 1, 2006. The Company’s share-based compensation
plans authorize the granting of various equity-based incentives including stock options, restricted stock and
restricted share units to employees and non-employee directors and agents. The expense for these equity-based
incentives is based on their fair value at date of grant or each reporting date and amortized over their vesting
period. The fair value of each stock option is estimated on the date of grant or each reporting date using the
Black-Scholes closed-form pricing model. The pricing model requires assumptions such as the expected life of
the option and expected volatility of the Company’s stock over the expected life of the option, which
significantly impacts the assumed fair value. The Company uses historical data to determine these assumptions
and if these assumptions change significantly for future grants, share-based compensation expense will fluctuate
in future periods.

Prior to January 1, 2006, the Company accounted for share-based compensation plans for employees and
non-employee directors under the measurement and recognition provisions of Accounting Principles Board
Opinion 25, “Accounting for Stock Issued to Employees” (“APB 25”) and related Interpretations, as permitted by
Statement of Financial Accounting Standards 123, “Accounting for Stock-Based Compensation” (SFAS 123”).
Had compensation cost of the employee and non-employee directors plans for 2005 and 2004 been determined
based on the fair values at the grant dates consistent with the method of SFAS 123, the Company’s pro-forma net
earnings and net earnings per share information would have been as follows:

l. New Accounting Standards

Adoption of Recent Accounting Pronouncements

In September 2006, the FASB issued SFAS No. 158, “Employers’ Accounting for Defined Benefit Pension
and Other Postretirement Plans, an amendment of FASB Statements No. 87, 88, 106, and 132(R)” (“SFAS 158”)
which requires employers of defined benefit pension and postretirement benefit plans other than pensions
(collectively “benefit plans”) to recognize the funded status of their benefit plans in their balance sheet, measure
the fair value of plan assets and benefit obligations as of the date of the fiscal year-end balance sheet date thereby
eliminating the use of an earlier measurement date and provide additional disclosures. The new measurement
date requirement is not effective until fiscal years ended after December 15, 2008. On December 31, 2006, the
Company adopted the recognition and disclosure provisions of SFAS 158. The adoption of SFAS 158 had no
effect on the Company’s consolidated statement of income for year ended December 31, 2006, or for any prior
period presented, and it will not affect the Company’s operating results in future periods. Adopting SFAS 158
required the Company to recognize the funded status (i.e. the difference between the fair value of plan assets and
the benefit obligations) of its postretirement plans in the December 31, 2006 balance sheet, with a corresponding
adjustment to accumulated other comprehensive income, net of tax. The $63.9 million adjustment to accumulated
other comprehensive income at adoption represents the following:

•

•

For the defined benefit pension plan: net unrecognized actuarial losses of $77.4 million ($50.3 million
net of tax); unrecognized prior service costs of $3.4 million ($2.2 million net of tax); unrecognized
transition asset remaining from the initial adoption of SFAS 87 of $3.0 million ($1.9 million net of
tax), all of which were previously netted against the plan’s funded status in the Company’s balance
sheet pursuant to the provisions of SFAS 87. These amounts will be subsequently recognized as a
component of the Company’s net periodic pension cost (benefit) pursuant to the Company’s historical
accounting policy for amortizing and allocating such amounts. The amount expected to be recognized
during the fiscal year ending December 31, 2007 for the State Auto Group is $3.9 million ($2.5 million
net of tax), $0.5 million ($0.3 million net of tax), and a benefit of $0.6 million ($0.4 million net of tax),
respectively.

For the postretirement benefit plan other than pensions: net unrecognized actuarial losses of $23.6
million ($15.3 million net of tax); unrecognized prior service costs of $3.2 million ($2.1 million net of
tax), all of which were previously netted against the plan’s funded status in the Company’s balance
sheet pursuant to the provisions of SFAS 106. These amounts will be subsequently recognized as a
component of the Company’s net periodic pension cost (benefit) pursuant to the Company’s historical
accounting policy for amortizing and allocating such amounts. The amount expected to be recognized
during the fiscal year ending December 31, 2007 for the State Auto Group is $0.8 million ($0.5 million
net of tax) and $0.5 million ($0.3 million net of tax), respectively.

Notes to Consolidated Financial Statements, Continued

At December 31, 2006, the Company continues to use the earlier measurement date of September 30, and is
currently reviewing the transition alternatives available. The adoption did not have an impact on the Company’s
debt covenants.

In December 2004, the FASB issued SFAS 123(R) which supersedes APB Opinion No. 25, “Accounting for
Stock Issued to Employees” (“APB 25”), and amends SFAS No. 95, “Statement of Cash Flows.” SFAS 123(R)
requires all share-based payments to employees, including grants of employee stock options, to be recognized as
expense based on their fair values. Pro forma disclosure is no longer an alternative. The Company adopted SFAS
123(R) on January 1, 2006, using the modified prospective method and, accordingly, the financial statements for
prior periods do not reflect any restated amounts. In accordance with SFAS 123(R), the Company is required to
record compensation expense for all awards granted after the date of adoption and for the unvested portion or
previously granted awards that remain outstanding at the date of adoption. As a result of adopting SFAS 123(R)
on January 1, 2006, the Company’s income before income taxes and net income for the year ended December 31,
2006 are $6.6 million and $4.9 million lower, respectively, than if the Company had continued to account for
share-based payments under APB 25. Basic and diluted earnings per share for the year ended December 31, 2006
are $0.12 and $0.12 lower, respectively,
than if the Company had continued to account for share-based
compensation under APB 25.

Pending Adoption of Accounting Pronouncements

In September 2006, the FASB issued FASB Statement 157, “Fair Value Measurements” (“SFAS 157”),
which is to be effective for fiscal years beginning after November 15, 2007, and interim periods within those
fiscal years. SFAS 157 establishes a single authoritative definition of fair value, sets out a framework for
measuring fair value, and requires additional disclosures about fair-value measurements. The statement imposes
no requirements for additional fair-value measures in financial statements. The Company is currently assessing
the impact of this new guidance, but does not believe it will be material. The Company plans to adopt this
guidance effective January 1, 2008.

In June 2006, the FASB issued FASB Interpretation No. 48, “Accounting for Uncertainty in Income Taxes”
(“FIN 48”), which is to be effective for fiscal years beginning after December 15, 2006. FIN 48 clarifies the
accounting for income taxes by prescribing the minimum recognition threshold a tax position is required to meet
before being recognized in the financial statements. FIN 48 also provides guidance on derecognition,
measurement, classification, interest and penalties, accounting in interim periods, disclosure and transition. The
Company is currently assessing the impact of this new guidance, but does not believe it will be material. The
Company plans to adopt this new guidance effective January 1, 2007.

In February 2006, the FASB issued FASB Statement 155, “Accounting for Certain Hybrid Financial
Instruments—an amendment of FASB Statements No. 133 and 140” (“SFAS 155”), which is to be effective for
all financial instruments acquired or issued after the beginning of an entity’s fiscal year that begins after
September 15, 2006. SFAS 155 permits fair value re-measurement for any hybrid financial instruments that
contains an embedded derivative that would otherwise require bifurcation, clarifies which interest only strips and
principal-only strips are not subject to the requirements of Statement 133, establishes a requirement to evaluate
interests in securitized financial assets in order to identify interests that are freestanding derivatives or that are
instruments that contain an embedded derivative requiring bifurcation, clarifies that
hybrid financial
concentrations of credit risk in the form of subordination are not embedded derivatives, and amends Statement
140 to eliminate the prohibition on a qualifying special-purpose entity from holding a derivative financial
instrument that pertains to a beneficial interest other than another derivative financial instrument. The Company
assessed the impact of this new guidance, and it will not be material. The Company plans to adopt this guidance
effective January 1, 2007.

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. SOP 05-1 provides guidance on accounting for deferred acquisition costs associated with
modifications to or the internal replacement of insurance contracts. SOP 05-1 focuses on modifications to
contracts with integrated product features and internal replacement of contracts in which the new contract offers
product features not included in the old contract when both were priced together. The Company’s insurance
contracts include only nonintegrated contract features as defined in SOP 05-1, which are contract features that
provide coverage that is underwritten and priced only for that incremental insurance coverage and that do not
result in re-underwriting or re-pricing 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 by the Company, the impact of SOP 05-1 upon implementation will not be material. The
Company plans to adopt this guidance effective January 1, 2007.

2. Investments

The Company recognized realized losses on other-than-temporary impairments of $3.8 million, $0.6 million
and $0.2 million on its fixed maturity portfolio in 2006, 2005, and 2004, respectively. The Company recognized
realized losses on other-than-temporary impairments of $1.6 million and $1.0 million in 2006 and 2005,
respectively on its equity security portfolio. There were no realized losses on other-than-temporary impairments
on the Company’s equity portfolio in 2004. The Company reviewed its investments at December 31, 2006, 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 would indicate temporary impairment.

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

$24.7 million and $18.0 million at December 31, 2006 and 2005, respectively.

During 2006 the Company continued to allocate new monies and reinvestments to tax-exempt bonds,
targeting an allocation of 70% of the total portfolio, in an effort to maximize after tax investment income. During
the fourth quarter of 2006, the Investment Committee of the Board of Directors of each of State Auto’s insurers
approved a $50.0 million repositioning of the current taxable and tax-exempt holdings intending to reach the
targeted 70% tax-exempt allocation at a quicker pace.

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
within a reasonable period of time and evidence to the contrary in considering the severity and duration of the
impairment in relation to the anticipated market price recovery.

The Company participated in a securities lending program whereby certain fixed maturity and equity
securities from the Company’s investment portfolio were loaned to other institutions for short periods of time.
The Company required collateral, equal to 102% of the market value of the loaned securities. Market values were
determined as defined in Note 3 pertaining to investment securities. The collateral was invested by the lending
agent, in accordance with Company’s guidelines, generating investment income, net of applicable fees. The
Company accounted for this program as a secured borrowing and recorded the collateral held and corresponding
liability to return the collateral on its balance sheet. The Company discontinued its participation in the securities

lending program effective June 30, 2006. At December 31, 2005,
the amount of collateral held was
approximately $99.0 million and the market value of securities lent was approximately $96.0 million. At
December 31, 2006, the Company had no securities on loan to others.

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: The carrying amount of the Trust Preferred note (defined in Note 6c) in the consolidated

The Company recorded favorable loss and loss expense reserve development in 2006, 2005, and 2004 of
$71.7 million, $44.3 million and $22.2 million, respectively. The favorable development in 2006 was primarily
due to ceded losses being above previously anticipated levels by $23.7 million, auto liability losses being $24.7
million less than anticipated because more mature claim data resulted in lower average claim severities than in
past projections, and loss adjusting expenses declining by $13.5 million in proportion to losses. The favorable
development in 2005 was largely due to ceded reserves being above previously anticipated levels by $14.8
million, catastrophe losses associated with the 2004 hurricanes developing $5.8 million better than previous
estimates, and loss adjustment expenses developing favorably by $13.7 million in proportion to losses. The 2004
favorable development relates to normal fluctuations associated with the loss development and claim settlement
process.

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.

Notes to Consolidated Financial Statements, Continued

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 State Auto 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 is
summarized as follows:

6. Transactions with Affiliates

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 State Auto
Mutual. Effective January 1, 2005, the Pooling Arrangement was amended to add as participants Meridian
Insurance Company
Security Insurance Company (“Meridian Security”) and Meridian Citizens Mutual
(“Meridian Citizens”), Indiana domiciled property and casualty insurers. Meridian Security is a wholly-owned
subsidiary of Meridian Insurance Group, Inc. (“MIGI”), which is wholly-owned by State Auto Mutual. MIGI is
party to an affiliation agreement with Meridian Citizens. Meridian Security and Meridian Citizens Mutual are
hereafter referred to collectively as the “MIGI Insurers” and together with MIGI as the “MIGI Companies”. SA
Wisconsin and SA Florida are wholly owned subsidiaries of State Auto Mutual.

In conjunction with the Pooling Arrangement amendment, the STFC Pooled Companies received $54.0
million in cash from the MIGI 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:

Under the Pooling Arrangement, the STFC Pooled Companies, SA Wisconsin, SA Florida and the MIGI
Insurers cede to State Auto Mutual all of their insurance business and assume from State Auto 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 State Auto
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 State Auto Mutual as assets only in situations when net
amounts ceded to State Auto Mutual exceed that assumed. The STFC Pooled Companies’ pooling percentage has
remained at an 80% participation level since 2001. All parties that participate in the Pooling Arrangement have
an A.M. Best rating of A+ (Superior).

The STFC Pooled Companies, SA National, State Auto Mutual, SA Wisconsin, SA Florida and the MIGI

Insurers are collectively referred to as the “State Auto Group.”

State Auto P&C assumes catastrophe reinsurance from the State Auto Group in the amount of $100.0
million excess of $135.0 million ($120 million prior to July 1, 2006) in exchange for a premium paid by each
reinsured company. Under this agreement, the Company has assumed from State Auto Mutual and its affiliates
premiums written and earned of $3.0 million, $2.7 million and $2.7 million for 2006, 2005 and 2004,
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.

As of July 1, 2005, SA National and State Auto Mutual terminated a reinsurance agreement between the
parties that included excess of loss and quota share coverages. SA National and State Auto 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, State Auto 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, State Auto 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, State Auto 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 State Auto 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 State
Auto Mutual from insurers, agents and reinsurers, which are offset by the unearned premium from the respective
policies. The Company’s share of the premium balances due to State Auto Mutual from agents and insureds at
December 31, 2006 and 2005 is approximately $250.3 million and $255.1 million, respectively.

c. Notes Payable

In May 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
common securities (the “Trust Securities”) is payable quarterly at a rate equal to the three-month LIBOR rate
plus 4.20%, adjusted quarterly (total 9.57% at December 31, 2006). 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.

95

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

Notes to Consolidated Financial Statements, Continued

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 2006, 2005, and 2004) as the underlying interest
expense is recognized on the Trust Securities.

On December 27, 2005, State Auto Financial repaid a $45.5 million line of credit it had with State Auto
Mutual. This repayment was 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.

d. Management Services

Stateco provides State Auto Mutual and it’s 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
$2.5 million, $2.3 million and $2.5 million in 2006, 2005 and 2004, respectively, and is included in other income
(affiliates).

State Auto P&C provides management and operation services to certain of State Auto Mutual’s insurance
affiliates for a fee. Revenue relating to these services amounted to $0.2 million, $0.3 million and $1.0 million in
2006, 2005 and 2004, respectively, and is included in other income (affiliates).

e. Other Transactions

State Auto P&C’s December 31, 1990 liability for losses and loss expenses of $65.5 million has been
guaranteed by State Auto Mutual. Pursuant to the guaranty agreement, all ultimate adverse development of the
December 31, 1990 liability, if any, is to be reimbursed by State Auto Mutual to State Auto P&C in conformance
with pooling percentages in place at that time. Through December 31, 2006, there has been no adverse
development of the guaranteed liability. As of December 31, 2006, the remaining loss and loss expense liability
is approximately $0.9 million.

7. Notes Payable and Credit Facility

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 2006, 2005 and 2004) as the underlying
interest expense is recognized on the Trust Securities.

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 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, 2006, 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 at December 31, 2006 and 2005.

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.

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

Notes to Consolidated Financial Statements, Continued

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
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. The defined benefits
and postretirement benefit plans are referred to herein as “the benefit plans.”

On December 31, 2006, the Company adopted the recognition and disclosure provisions of SFAS 158.
SFAS 158 required the Company to recognize the funded status of its plans (collectively “the benefit plans”) in
the December 31, 2006 balance sheet, with a corresponding adjustment to accumulated other comprehensive
income, net of tax. The adjustment to accumulated other comprehensive income at adoption represents the net
unrecognized actuarial losses, unrecognized prior service costs, and unrecognized transition assets remaining
from the initial adoption of SFAS 87 and 106, all of which were previously netted against the plans’ funded
status in the Company’s balance sheet pursuant to the provisions of SFAS 87 and 106. These amounts will be
subsequently recognized as net periodic cost pursuant
to the Company’s historical accounting policy for
amortizing such amounts. Further, actuarial gains and losses that arise in subsequent periods and are not
recognized as net periodic cost in the same periods will be recognized as a component of other comprehensive
income. Those amounts will be subsequently recognized as a component of net periodic cost on the same basis as
the amounts recognized in accumulated other comprehensive income at adoption of SFAS 158.

The following table provides the incremental effects of adopting the provisions of SFAS 158 on the
Company’s balance sheet at December 31, 2006. The adoption of SFAS 158 had no effect on the Company’s
consolidated statement of income for the year ended December 31, 2006, or for any prior period presented, and it
will not affect the Company’s operating results in the future.

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, 2006 of 8.9%.

The assumed health care cost trend rates used for the year ended December 31 are as follows:

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 2005 measurement date pursuant to FSP 106-2.

The Company’s benefit plans’ weighted average asset allocations by asset category at

the plans’

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 publicly 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.

assets’ fair market value:

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 $12.0 million during 2007 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 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 $2.5 million, $2.4 million and $2.2 million for the
years 2006, 2005 and 2004, respectively.

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. Share-Based Compensation

Prior to January 1, 2006, the Company accounted for share-based compensation plans for employees and
non-employee directors under the measurement and recognition provisions of Accounting Principles Board
Opinion 25, “Accounting for Stock Issued to Employees,” and related Interpretations, as permitted by Statement
of Financial Accounting Standards 123, “Accounting for Stock-Based Compensation” (“SFAS 123”).
Accordingly, share-based compensation was included as a pro forma disclosure in the financial statement
footnotes (See Note 1k—Share-Based Compensation). For share-based awards granted to the Company’s
independent
the Company recognized share-based compensation within its financial
statements in accordance with SFAS 123 and related Interpretations.

insurance agencies,

The Company maintains share-based compensation plans for

its key employees and outside, or
non-employee, directors. The share-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”).

Equity 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,

105

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

Notes to Consolidated Financial Statements, Continued

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, 2006, a total of 1,502,147 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.

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 the 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 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. Stock options granted under the Equity Plan for 2006 and
2005 were 0.3 million and 0.4 million, respectively.

The Equity Plan provides for the granting of restricted shares subject to a vesting schedule based on the
employee’s continued employment (“Restriction Period”), for which vesting is generally on the third anniversary
after the date of grant. The Company recognizes compensation expense based on the number of restricted shares
granted at the then grant date fair value over the Restricted Period. Restricted shares granted for 2006 were
10,500 with an average grant date fair value of $31.94. There were no restricted shares granted by the Company
prior to January 1, 2006.

As of December 31, 2006, there was $0.2 million of total unrecognized compensation cost related to
non-vested share-based compensation arrangements granted under the plans. The remaining cost is expected to
be recognized over a period of 2.25 years. No shares vested during the year ended December 31, 2006.

Employee Stock Purchase Plan

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

106

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

Notes to Consolidated Financial Statements, Continued

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, 2006, a total of
2.3 million common shares have been purchased under this plan.

Outside Directors Plan

Under the Outside Directors Stock Option Plan, following each annual meeting of shareholders, outside
directors received nonqualified 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 nonqualified 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, however, the amount of the award may change from year to year, based on the provision described
below. 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. Such election may be changed within the constraints set forth in the
RSU Plan. 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 accounts for the Outside Directors RSU Plan as a liability plan. There were 9,800 RSUs granted in
both 2006 and 2005.

The Company distributed shares worth approximately $60,000 under the Outside Directors RSU Plan in

2006. No distributions were made in 2005.

Agent Stock Option Plan

The Company has a stock option incentive plan for certain designated independent insurance agencies
(“Agent Stock Option Plan”) that represent
the Company and its affiliates. The Company has reserved
0.4 million shares of common stock under this plan. As of September 30, 2006, a total of 0.2 million shares were
available for issuance under the Agent Stock Option 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. Stock options granted for the years 2006 and 2005 were 16,452 and 29,505, respectively.

Stock Options

The fair value of each stock option granted is estimated on the date of grant using the Black-Scholes closed-
form pricing model. The following tables present the weighted-average assumptions used in the option pricing
model for options granted to employees and non-employees (independent insurance agencies) during 2006, 2005,
and 2004. The expected life of the options for employees represents the period of time the options are expected to
be outstanding and is based on historical trends. For non-employees the expected life of the option approximates
the remaining contractual term of the option. The expected stock price volatility is based on the historical
volatility of the Company’s stock for a period approximating the expected life and the expected dividend yield is
based on the Company’s most recent period’s dividend payout. The risk-free interest rate is based on the U.S.
Treasury yield curve in effect at the time of grant and has a term equal to the expected life.

The fair value of the agent options granted was estimated at the reporting date or vesting date using the
Black-Scholes option-pricing model. The weighted average fair value and related assumptions are as follows for
2006, 2005 and 2004:

15. Reportable Segments

At December 31, 2006, the Company has two significant reportable segments: standard insurance and
nonstandard insurance. 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.

Due to internal reorganization efforts that occurred throughout 2006 the Company’s significant reportable
segments will change, beginning with the first quarter of 2007, to personal insurance, business insurance and
investment operations. Prior reporting periods will be conformed to the new segment presentation.

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 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.

The Company’s insurance subsidiaries are involved in litigation and may become involved in potential
litigation arising in the ordinary course of business. Additionally, the insurance subsidiaries may be impacted by
adverse regulatory actions and adverse court decisions where insurance coverages are expanded beyond the
scope originally contemplated in the policies at December 31, 2006. In the opinion of management, the effects, if
any, of such litigation and published court decisions are not expected to be material to the consolidated financial
statements.

Item 9A. Controls and Procedures

Management’s Annual Report on Internal Control Over Financial Reporting

Our management’s annual report on internal control over financial reporting required by Item 308(a) of
Regulation S-K follows. The attestation report of our 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 our management on the Company’s internal control over financial

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

1. Our management

is responsible for establishing and maintaining adequate internal control over

financial reporting for the Company.

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

3. All internal control systems, no matter how well designed, have inherent limitations. Therefore, even
those systems determined to be effective can only provide reasonable assurance with respect to
financial reporting.

4. Our management has assessed the effectiveness of our internal control over financial reporting as of
December 31, 2006, and has concluded that such internal control over financial reporting is effective.
There are no material weaknesses in our internal control over financial reporting that have been
identified by our management.

Our management’s assessment of the effectiveness of our internal control over financial reporting as of
December 31, 2006, 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

We carried out an evaluation, under the supervision and with the participation of our management, including
our Chief Executive Officer and Chief Financial Officer, of the effectiveness of the design and operation of our
disclosure controls and procedures (as defined in Exchange Act Rule 13a-15(e)). Based upon that evaluation, our
Chief Executive Officer and Chief Financial Officer concluded that, as of the end of the period covered by this
report, our 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 our internal control over financial reporting that occurred during our most
recent fiscal quarter that has materially affected, or is reasonably likely to materially affect, our internal control
over financial reporting.

I, Robert P. Restrepo, Jr., certify that:

1.

I have reviewed this Form 10-K of State Auto Financial Corporation;

Exhibit 31.01

2. Based on my knowledge, this report does not contain any untrue statement of a material fact or omit to
state a material fact necessary to make the statements made, in light of the circumstances under which
such statements were made, not misleading with respect to the period covered by this report;

3. Based on my knowledge, the financial statements, and other financial information included in this
report, fairly present in all material respects the financial condition, results of operations and cash
flows of the registrant as of, and for, the periods presented in this report;

4.

The registrant’s other certifying officer and I are responsible for establishing and maintaining
disclosure controls and procedures (as defined in Exchange Act Rules 13a-15(e) and 15d-15(e)) and
internal control over financial reporting (as defined in Exchange Act Rules 13a-15(f) and 15d-15(f)) for
the registrant and have:

(a) Designed such disclosure controls and procedures, or caused such disclosure controls and
procedures to be designed under our supervision, to ensure that material information relating to
the registrant, including its consolidated subsidiaries, is made known to us by others within those
entities, particularly during the period in which this report is being prepared;

(b) Designed such internal control over financial reporting, or caused such internal control over
financial reporting to be designed under our supervision,
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;

(c) Evaluated the effectiveness of the registrant’s disclosure controls and procedures and presented in
this report our conclusions about the effectiveness of the disclosure controls and procedures, as of
the end of the period covered by this report based on such evaluation; and

(d) Disclosed in this report any change in the registrant’s internal control over financial reporting that
occurred during the registrant’s most recent fiscal quarter (the registrant’s fourth fiscal quarter in
the case of an annual report) that has materially affected, or is reasonably likely to materially
affect, the registrant’s internal control over financial reporting; and

5.

The registrant’s other certifying officer and I have disclosed, based on our most recent evaluation of
internal control over financial reporting, to the registrant’s auditors and the audit committee of the
registrant’s board of directors:

(a) All significant deficiencies and material weaknesses in the design or operation of internal control
over financial reporting which are reasonably likely to adversely affect the registrant’s ability to
record, process, summarize and report financial information; and

(b) Any fraud, whether or not material, that involves management or other employees who have a

significant role in the registrant’s internal control over financial reporting.
