dear Shareholders

We’re  pleased  with  State  Auto’s  excellent  2007  results,  in 
terms  of  the  numbers  and  the  development  of  our  infra-
structure.  Although  earnings  did  not  match  our  2006  per-
formance, we continued to make significant investments in 
products,  systems  and  services  necessary  to  predictably 
increase our long-term profit and growth. We added talent 
and  depth  to  an  already  strong  leadership  team  and  we 
completed  the  development  of  a  business  strategy—
approved  by  our  Board  of  Directors—  that  will  guide  us 
over the next three to five years. While most of this report 
details  what  happened  in  2007,  my  letter  includes  a 
number of references to our preparation for the future. Our 
business  strategy  focuses  on  four  performance  elements: 
underwriting  profitability;  growth;  capital  management; 
and  risk  management.  Our  strategy  also  recognizes—
indeed,  underscores—that  our  performance  is  absolutely 
dependent on our people.

You’ll also find in this report frequent reference to technology. 
I don’t subscribe to the clever suggestion that we’re in 
an IT business that happens to sell insurance. But I am of 
the  mind  that  our  overarching  determination  to  improve 
our  customers’  ease  of  doing  business  with  us  is  only 
achieved if we master the technologies required to sell,  
service and deliver our products.

Here  are  our  four  performance  elements,  today  and  in  
the future.

Underwriting: OUtperfOrming the indUstry
State  Auto’s  top  priority  remains  producing  an  under-
writing profit. That’s how we established and will continue 
to  maintain  our  superior  financial  profile.  Better-than-
expected  catastrophe  loss  experience  during  2007  was 
offset  by  pricing  and  lower  benefits  from  favorable  prior 
year  loss  development,  a  key  reason  why  2006  earnings 

were  slightly  higher  than  2007’s.  Nonetheless,  our  2007 
combined  ratio  was  92.8,  with  net  income  from  opera-
tions of $111 million. It added up to one of the best years 
in our history.

We  made  some  aggressive  pricing  decisions  in  2006  and 
early  2007  that  were  intended  to  help  us  retain  profitable 
business and give our field staff a stronger calling card for 
new business opportunities. The pricing decisions paid off. 
Loss ratios were slightly higher but impressive, especially in 
the  automobile  and  liability  lines.  Our  business  insurance 
teams proved adept at responding quickly to the competi-
tion, delivering exceptional products and services. We kept 
our  good  customers,  preserved  our  profitability  and  
demonstrated  to  our  agents  and  consumers  that  we  
are  serious  about  competing  in  our  expanding  markets.

Heading  into  2008  we  are  increasingly  confident  that  we 
will  see  a  slow  but  steady  turn  in  the  personal  insurance 
market.  After  several  years  of  rate  cutting  in  the  industry, 
automobile  insurance  pricing  should  stabilize  and  then 
begin  to  rise.  Our  new  standard  automobile  product, 
CustomFitSM,  produced  solid  results  in  2007.  We  believe  
we  have  the  products,  pricing  sophistication  and  agency 
plant  to  produce  increasing  under writing  profits  in  
personal automobile.

Homeowners  remains  a  challenge,  given  our  Midwestern 
orientation and exposure to wind and hail. We have several 
underwriting initiatives underway to improve short-term 
results.  Longer  term,  we  will  develop  new  pricing  models 
for homeowners that will improve our results in this under-
performing line.

We  expect  competition  in  business  insurance  to  remain 
strong in 2008. While we have given up some price to retain 
existing policyholders and attract new ones, such discount-
ing  has  been  modest  and  our  commercial  underwriting 
results remain excellent. Increasingly, we will rely on prod-
uct and service enhancements to retain our good business. 
In addition, we will begin introducing sophisticated predic-
tive  modeling  techniques  for  our  main  street  commercial 
lines products by mid-2008. As with personal auto, this will 
expand  our  pricing  flexibility  while  institutionalizing  our 
underwriting discipline.

From an underwriting standpoint, we are well positioned to 
outperform the industry as a whole and, more importantly, 
our peer group of regional insurance companies.

grOwth: when OppOrtUnity meets technOlOgy
After three years of declining written premium, we turned 
the corner in 2007.

In Business Insurance, we empowered our field underwriters 
to respond more quickly by expanding their authority con-
sistent  with  their  experience,  training  and  track  record. 
Additionally,  we  introduced  a  variety  of  new  product  and 
pricing programs enabling our field staff to say “yes” to the 
production  needs  of  our  independent  agency  partners 
without giving up the underwriting results critical to both 
the agent and the company. Lastly, we introduced bizXpressSM, 
an easy-to-use Web-based system that allows our agents to 
rate,  quote  and  begin  the  policy  issuance  process  in  
real-time. It accounted for a significant increase in our busi-
ness owners policy (BOP) production. In 2008, we will  
add  bizXpress  support  for  commercial  automobile  and 
workers’ compensation.

Personal  Insurance  posted  modest  premium  growth  in 
2007, an increased policy count and solid policy retention. 
Personal  auto  led  the  way  in  both  standard  and  non- 
standard  lines.  Our  new  standard  automobile  product, 
CustomFit,  continues  to  shine.  Its  pricing  flexibility  and 
coverage features are attractive to consumers and producers. 
By the end of 2008, we expect to have CustomFit available 
in  all  of  our  states.  After  three  straight  years  of  negative 
growth,  State  Auto’s  non-standard  auto  product  finished 
2007  with  positive  growth.  We  believe  our  prospects  for 
personal auto are bright.

With  new  products  supported  by  improved  services  and 
systems,  we’ll  begin  focusing  on  our  sales  management 
capability.  Frankly,  it  needs  our  focus.  Our  average  premi-
ums per agent are below industry norms and well short of 
our  potential.  In  November  we  added  Clyde  Fitch  to  our 
management  team  as  chief  sales  officer.  Clyde  brings  a 
wealth of experience from two large national insurers, and 
a proven ability to build superior sales organizations.

There  are  basically  two  ways  to  grow  in  our  industry: 
increase  sales  through  your  existing  structure—it’s  called 
organic or same store sales—and/or expand that structure 
through acquisitions and affiliations. A&A is the best use of 
our capital and an important supplement to our strategies. 
During  2007,  State  Auto  Mutual  completed  two  transac-
tions  and  began  to  integrate  the  Beacon  Insurance 
Group and the Patrons Group. Together, these transactions 
allowed  us  to  enter  five  new  states:  Texas,  Connecticut, 
Massachusetts, Rhode Island and Vermont. Our total num-
ber  of  operating  states  has  grown  to  33,  adding  approxi-
mately $95 million in direct written premium to State Auto 
and providing us with significant cross-selling opportu-
nities,  particularly  in  the  personal  auto  and  business 
insurance lines.

We  remain  active  in  the  A&A  market  going  into  2008,  
targeting companies that have:

•  $50 to $250 million in written premium with the potential 

to be immediately accretive to earnings;

•  good  underwriting  and  claim  fundamentals,  strong 
agency  relationships,  and  the  cultural  compatibility  that 
is critical to successful integration;

•  problems  that  we  can  help  solve,  including  geographic 
concentration,  an  inability  to  invest  in  new  technology, 
and an over-dependence on reinsurance. 

As the market continues to soften and underwriting results 
deteriorate, we anticipate more opportunities will arise.

capital management: mOney at wOrk
In  2007,  we  took  several  capital  management  actions  that 
we  think  are  very  responsive  to  your  expectations  as 
shareholders.

In  March  State  Auto  Mutual  completed  the  acquisition  of 
the Beacon Insurance Group, and in December completed 
an affiliation with the Patrons Group.

In  July,  we  refinanced  and  expanded  our  credit  capacity  
to achieve the liquidity and flexibility we need to support

our  capital  management  and  A&A  plan.  We  completed  
this  transaction  well  before  the  current  turmoil  in  the  
credit markets.

In  November  we  announced  a  50%  increase  to  our  divi-
dend.  This  change  provides  our  shareholders  a  very  com-
petitive  yield  and  enhances  our  total  return  prospects  for 
the  future.  We  also  announced  a  Board-authorized  stock 
repurchase  plan  that  allows  us  to  repurchase  up  to  
four million shares of STFC stock through 2009. The stock 
will  be  repurchased  proportionately  from  State  Auto  
Mutual and our public shareholders based on their respec-
tive ownership percentages. Preserving and leveraging our 
strong  capital  position  is  both  a  high  priority  and  our  
biggest challenge.

enterprise risk management
Along with our desire to be a more responsive underwriter 
and  marketer  is  our  commitment  to  manage  risk.  In  2007  
we  created  a  function  within  the  company  dedicated  to 
enterprise risk management. This is not a matter of simply 
satisfying  our  conservative  side—it’s  smart  business.  
The objectives of our enterprise risk management include:

•  balancing the risks we assume and the prices we charge 

to produce stable underwriting profits;

•  reserving for losses in a way that realistically and conser-
vatively approximates what our ultimate payment will be;
•  investing our cash flow in securities that are highly rated, 

relatively liquid, and produce good total returns;

•  entering into reinsurance agreements that are responsive 
to our risk management needs and secure from a credit 
standpoint; and

•  implementing  business  continuity  plans  that  effectively 

anticipate the worst.

State Auto has performed each of these quite well for some 
time,  but  we  can  always  improve.  Demands  from  rating 
agencies have intensified and our own view of risk has been 
sharpened. Not only was 9/11 a devastating human loss, it 
was also a terrible financial loss, showing how many things 
can  go  wrong  at  the  same  time.  The  insurance  industry  
suffered  a  tremendous  underwriting  loss  that  destabilized 
the  capital  and  reinsurance  markets  and  challenged  the 
business  continuity  plans  of  many  companies.  The  recent 
turmoil in the financial and credit markets has also revealed 
the importance of risk management programs.

I want to finish this review by acknowledging, again, our 
people. This is where are our 2007 success really begins. 
They have managed very well the business and leadership 
changes in our company over the last two years. I couldn’t 
be  prouder  of  our  team,  or  more  excited  about  their  will-
ingness and ability to take on the challenges ahead. We’ve 
shifted into a higher sales gear, and they have embraced it. 
We’ve been open about our preference for technology and 
the inordinate resources it requires, and they have bought 
in. We’ve talked about paying for performance and develop-
ing new skills and rethinking the way we evaluate our sys-
tems, our work and each other. And they’re on board.

In 2008 we will continue to focus on personal development, 
rewards  and  human  resource  management  and  training.  
I’m confident in our people and our prospects, and believe 
we are well on our way to becoming the company of choice 
for all our stakeholders.

In 2007 we continued to broaden our review with the Board 
of  Directors  of  all  significant  risks  that  we  face  as  a  com-
pany and an industry.

STFC must continue to grow. We’ll do so by giving our agents 
the  tools  they  need  to  promote  and  service  our  products. 
We’ll be selective in choosing new agents, and we expect to 
become a preferred company in every agency. We will earn 
that status by being more flexible and better listeners. All the 
while,  we  will  continue  to  foster  the  bond  with  our  agents 
that  we’re  noted  for.  Achieving  organic  growth  through  our 
existing  agency  force  is  important  because  it’s  growth  built 
on strong, profitable, existing books of business.

State  Auto’s  business  insurance  division  recognizes  three 
market sectors. Our ability to compete for small accounts is 
dependent on pricing accuracy and transaction speed. Success 
in writing large accounts relies more on the quality of our risk 
management tools, because the insurance buyer is assuming a 
greater share of the potential losses. The business in the middle 
is  best  pursued  by  skilled  underwriters  who  work  closely 
with their agents and are empowered to make underwriting 
decisions in the field.

We’ll  also  grow  through  acquisition  and  affiliation.  This  is 
the more dramatic way to grow, but it needs to be done care-
fully  and  thoughtfully.  We  have  a  reputation  for  integrity, 
honesty  and  treating  our  acquired  companies  well.  But  a 
friendly  acquisition  (and  all  of  ours  have  been  friendly) 
brings  with  it  challenges  in  staffing  integration,  licensing, 
systems migration—especially systems migration.

In  Personal  Insurance  we  now  use  multivariate  pricing  and 
predictive  modeling  to  attract  accounts  with  the  greatest 
potential for profit. While pricing will never entirely replace the 
personal application of underwriting principals, the melding of 
proven  underwriting  practices  with  greater  information  and 
pricing  precision  is  a  strategy  that  is  expected  to  continue 
our well-earned reputation for consistently producing profit.

In 2007 we took advantage of market conditions and expanded 
our  bank  line  of  credit  to  $200  million.  We  implemented  a 
share repurchase program to return capital to shareholders if 
conditions  warrant.  We  increased  our  quarterly  dividend  to 
$0.15  per  share,  reflecting  the  confidence  we  have  in  our 
operations  and  future  prospects.  On  January  1,  2008,  STFC 
began  assuming  insurance  business  from  the  Beacon 
Insurance  Group  and  the  Patrons  Insurance  Group  through 
the State Auto reinsurance pooling agreement.

State Auto’s first acquisition was Milbank Insurance Company 
in 1993. It went so well that we encouraged potential acquisi-

assurance that State Auto lived up to its promises.

enteRpRiSe RiSk management

Insurance companies are typically very good at risk manage-
’06
ment. But there’s a difference between addressing risk effectively 
at the business unit level and addressing the joint management 
of risk and capital at the corporate level. Underwriting, reserving, 
cash  flow  investment,  reinsurance,  disaster  recovery—these 
are among the functions and responsibilities across the entire 
organization that warrant the attention of the Enterprise Risk 
Management (ERM) function.

ERM is holistic in its approach. It’s not just about reducing 
or  eliminating  risk.  It’s  about  understanding  it  better.  A 
proactive ERM program, when done well, reduces surprises, 
promotes  better  decision-making  and  serves  as  a  strategic

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.

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.

Our parent company is State Auto Mutual, an Ohio domiciled super-regional mutual property and casualty
insurance company organized in 1921. It owns approximately 64% 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 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. MIGI also owns 100% of State
Auto Holdings, Inc., an insurance holding company, which owns 100% of the Beacon Insurance Group. In March
2007, State Auto Mutual completed its purchase of the Beacon Insurance Group of Wichita Falls, Texas. With
this acquisition, Texas became the State Auto Group’s 29th state of operation. The Beacon Insurance Group is
comprised of Beacon National and Beacon Lloyds, which are affiliated through a trust agreement. Beacon
National and Beacon Lloyds wrote premiums during 2007 in Texas and Arkansas. In December 2007, State Auto
Mutual completed its affiliation with the Patrons Insurance Group. This affiliation expanded the State Auto
Group’s operations to 33 states by adding Connecticut, Massachusetts, Rhode Island and Vermont.

State Auto P&C has participated in a quota share reinsurance pooling arrangement with State Auto Mutual
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. On January 1, 2008, Beacon National, Patrons Mutual and
Litchfield became participants in the Pooling Arrangement. See “Narrative Description of Business—Pooling
Arrangement” in this Item 1 for further information regarding the Pooling Arrangement.

The State Auto Group markets 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 independent insurance agencies in
33 states. Our Pooled Companies and SA National are rated A+ (Superior) by the A.M. Best Company.

(b) Financial Information about Segments

We have three significant reportable segments: personal insurance and business insurance (the “insurance
segments”), and investment operations. The insurance segments are managed separately because of the
the insurance
differences in types of customers served, products provided or services offered. In 2007,
segments distributed their products through the independent agency system in 29 states. The personal insurance
segment provides primarily personal auto (standard and nonstandard) and homeowners to the personal insurance
market. The business insurance segment provides primarily commercial auto, commercial multi-peril, fire and
allied lines, other and product liability and workers’ compensation insurance to small to medium sized businesses
within the commercial insurance market, which in 2008 includes middle market business. The investment
operations segment, managed by Stateco, provides investment services for our Company’s invested assets.

2

Prior to 2007, we reported our financial information in two segments, a standard insurance segment and a
nonstandard insurance segment. We believe that our new segments better reflect the manner in which we manage
our business and report our results internally to our principal operating decision makers. We established
integrated personal and business insurance teams with product and profit responsibilities for their respective
areas. We evaluate the performance of our insurance segments using industry financial measurements based on
Statutory Accounting Principles (“SAP”), which include loss and loss adjustment expense ratios, underwriting
expense ratios, combined ratios, statutory underwriting gain (loss), net premiums earned and net written
premiums. Prior reporting periods have been restated to conform to the new segment presentation.

(c) Narrative Description of Business

Property and Casualty Insurance

Pooling Arrangement

Our Pooled Companies are parties to the “Pooling Arrangement.” In general, 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 2001. Prior to 2008, the Pooling Arrangement covered all property and
casualty insurance written by the Pooled Companies except State Auto Mutual’s voluntary assumed reinsurance,
middle market business insurance written by State Auto Mutual and Meridian Security and intercompany
catastrophe reinsurance written by State Auto P&C.

In 2008, we made the following changes to the Pooling Arrangement:

•

•

•

•

Added Beacon National to the pool with a participation percentage of 0.0%;

Added Patrons Mutual and Litchfield to the pool with participation percentages of 0.4% and 0.1%,
respectively;

Reduced State Auto Mutual’s participation percentage from 19.5% to 19.0% to accommodate the
participation percentages allocated to Patrons Mutual and Litchfield;

Included State Auto middle market business insurance written by State Auto Mutual and Meridian
Security.

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, 1997:

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

It is not management’s intention to recommend an adjustment to the STFC Pooled Companies’ 80%
the Pooling
in the foreseeable future. Under applicable governance procedures,
participation level
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 STFC. The Pooling Arrangement is terminable by any of our Pooled Companies at
any time by any party by giving twelve months notice to the other parties and their respective domiciliary
insurance departments. None of our Pooled Companies currently intends to terminate the Pooling Arrangement.

if

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
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 Pooling Arrangement excludes catastrophic losses and loss adjustment expenses that are reinsured
under our Catastrophe Assumption Agreement (defined below), 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 in the amount of $100.0
million in excess of $135.0 million. No losses were paid by State Auto P&C under the Catastrophe Assumption
Agreement in 2007, 2006 or 2005. The State Auto Group does not currently intend to renew the Catastrophe
Assumption Agreement upon its expiration on July 1, 2008. The State Auto Group is considering other
alternatives, such as securing replacement coverage from a third party reinsurer or relying upon the $100 million
set aside under the Credit Agreement (defined below) to fund this layer of catastrophe reinsurance, but currently
no decision has been reached. See “Narrative Description of Business—Reinsurance” in this Item 1 for further
information regarding the Catastrophe Assumption Agreement.

Our nonstandard automobile programs, written through SA National, 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 the Pooling
Arrangement. See “Narrative Description of Business—Marketing” for further information regarding our
nonstandard auto insurance business.

Management Agreement

With the exception of the Patrons Group (discussed below), our subsidiary, State Auto P&C, provides the
employees to perform all organizational, operational and management functions for the State Auto Group and

4

State Auto Mutual provides certain operating facilities, including our corporate headquarters, for the State Auto
Group through management and cost sharing agreements. Each of the affiliated management and cost sharing
agreements has a ten-year term and renews for an additional ten-year period unless terminated sooner in
accordance with their terms. If our primary management agreement, which we refer to as our 2005 Management
Agreement, were 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. See also Item 2
(Property) of this Form 10-K.

On December 14, 2007, State Auto Mutual and State Auto P&C became parties to various management and/
or cost sharing agreements in conjunction with State Auto Mutual’s affiliation with the Patrons Insurance Group.
Each of these management and/or cost sharing agreements apportions among the parties the actual costs of the
services provided. Employees of the Patrons Group will remain employees of Patrons Mutual until January 1,
2009, at which time it is expected that they will become employees of State Auto P&C. The insurance operations
of the Patrons Group will continue to be conducted at facilities owned by Patrons Mutual and Litchfield.

Marketing

As of January 1, 2008, the State Auto Group marketed its products in 33 states through independent
insurance agencies. None of the companies in the State Auto Group has any contracts with managing general
agencies.

We view our independent insurance agents as our primary customers, because they are in a position to
recommend either our insurance products or those of a competitor to their customers. We strongly support the
independent agency system and believe its maintenance 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; contingent commissions; 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, as well as in our agents’ offices.

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 contingent commissions 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, we make available to our agents a stock purchase plan which provides them with the opportunity to

5

use their commission income to purchase our stock. Our transfer agent administers this stock purchase plan using
commission dollars assigned by the agents to purchase shares on the open market through a stockbroker. We also
make available to our top performing agents a stock option plan which provides them with the opportunity to vest
grants of options in our stock if they meet certain performance targets.

During 2007, the State Auto Group, which includes the Beacon and Patrons Groups, received premiums on
products marketed in Alabama, Arizona, Arkansas, Colorado, Connecticut, Florida, Georgia, Illinois, Indiana,
Iowa, Kansas, Kentucky, Maryland, Massachusetts, Michigan, Minnesota, Mississippi, Missouri, North Carolina,
North Dakota, Ohio, Oklahoma, Pennsylvania, Rhode Island, South Carolina, South Dakota, Tennessee, Texas,
Utah, Vermont, Virginia, West Virginia and Wisconsin. During 2007, the eight states that contributed the
greatest percentage of our direct premiums written were as follows: Ohio (17.1%), Kentucky (10.2%), Indiana
(6.9%), Tennessee (6.3%), Pennsylvania (4.6%), Minnesota (4.6%), Maryland (4.4%) and Arkansas (4.1%).

Claims

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.

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 claim service 24 hours a day, seven days a week, 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.

6

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.”

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

loss expenses for each of the three years in the period ended December 31:

The following table sets forth our development of reserves for losses and loss expenses from 1997 through
2007. “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 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, 2007, we have paid 92.4% of
the currently estimated losses and loss expenses that had been incurred, but not paid, as of December 31, 1997.

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 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 $28.0 million or
14.4% deficiency through December 31, 2007. This $28.0 million amount has been included in operating results
over the ten years and did not have a significant effect on income in any one year.

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
2000, but incurred in 1997, 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 the MIGI Insurers. The amount of the assets transferred on the reserve liabilities assumed 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

9

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.

During 2007, the Beacon Group was added to the State Auto Group’s reinsurance programs described below

and as of January 1, 2008, the Patrons Group was added to these programs.

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 100% 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 the $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 and certain companies. 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. (Facultative reinsurance provides for a separate reinsurance agreement that is negotiated for a particular
risk or insurance policy.)

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. The State Auto Group does not currently intend to renew the
Catastrophe Assumption Agreement upon its expiration on July 1, 2008. The State Auto Group is considering

10

other alternatives, such as securing replacement coverage from a third party reinsurer or relying upon the $100
million set aside under the Credit Agreement, discussed below, to fund this layer of catastrophe reinsurance, but
currently no decision has been reached.

On July 12, 2007, State Auto Financial terminated its then-current credit agreement and entered into a new
credit agreement (the “Credit Agreement”) with a syndicate of lenders which provides for a $200.0 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 $50.0 million, up to a maximum total facility amount of $250.0
million, provided that no event of default has occurred and is continuing. While the Credit Facility is available
for general corporate purposes, including working capital, acquisitions and liquidity purposes, we presently
intend to keep $100 million of the Credit Facility available in the event there is a need to fund losses under the
catastrophe reinsurance program with State Auto P&C. 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.

See “Narrative Description of Business—Regulation” of this Item 1 for a discussion of the Terrorism Risk

Insurance Act of 2002, and its successor, the Terrorism Risk Insurance Extension Act of 2005.

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 insurance subsidiary within 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
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.

11

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 at
December 31, 2007, adjusted for dividend payments made in the previous twelve-month period, a total of $79.6
million is available in 2008 for payment as a dividend from our insurance subsidiaries to STFC without prior
approval from our respective domiciliary state insurance departments. STFC received dividends of $50.0 million,
$0.0, and $40.5 million in 2007, 2006, and 2005, 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 2007 which would materially impact
our business.

In January 2007, the Florida legislature enacted new legislation which made fundamental changes to the
property and casualty insurance business in Florida. This legislation was intended to address the cost of
residential property insurance in Florida. After careful analysis of this legislation, we concluded that we could no
longer operate our personal lines on a profitable basis in that state. Accordingly, during the second quarter 2007,
we filed an application with the Florida Department of Insurance to withdraw from this state’s personal lines
insurance market effective January 1, 2008. Non-renewals on our personal lines business are in process. We will
continue to write commercial lines business in Florida.

Many of the states in which we operate have passed or are considering legislation restricting or banning the
use of “credit scoring” in the rating and risk selection process. In July 2007, the Federal Trade Commission
(“FTC”) released a report on credit scoring and its impact on automobile insurance. The FTC concluded that
credit-based scoring is an effective predictor of risk with respect to the issuance of automobile insurance policies
to consumers, but has little effect as an indicator of racial or ethnic status of consumers. Despite the FTC’s
conclusions, some consumer groups and certain regulatory and legislative entities continue to resist the use of
credit scoring in the rating and risk selection process. Banning or restricting this practice or data mining would
limit our ability, and the ability of other carriers, to take advantage of the predictive value of this information. An
FTC study reviewing the impact of credit scoring on homeowners insurance is pending. The homeowners
insurance study could affect the future use of credit scoring based upon the findings of the FTC.

In an attempt to make capital and surplus requirements more accurately reflect the underwriting risk of
different lines of insurance, as well as investment risks that attend insurers’ operations, the National Association
requirements. As of
of
December 31, 2007, 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.

12

The Terrorism Risk Insurance Act of 2002 and its successor, the Terrorism Risk Insurance Extension Act of
2005 (collectively, 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 the Terrorism Acts and that do not
arise out of nuclear, biological or chemical agents. In December 2007, The United States Congress extended the
Terrorism Acts through December 31, 2014. At the same time, Congress made modest changes to the Terrorism
Acts—for example, deleting the distinction between certified and non-certified (essentially foreign and domestic)
acts of terrorism. Lines of business covered, as well as certain important coverage features (such as loss triggers,
company deductibles and industry retentions) were not changed. We are evaluating these recent changes to the
Terrorism Acts and are taking actions to comply. Our current property reinsurance treaties exclude certified acts
of terrorism.

An area of regulatory focus in recent years and which may continue to receive additional attention in 2008 is
“producer compensation arrangements.” Beginning in 2006, 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. 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 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.

Investments

Our investment portfolio is managed to provide growth of statutory surplus to facilitate increased premium
writings over the long term while maintaining the ability to fund 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 its subsidiaries, although investment policies implemented by Stateco continue to be
set for each company through the Investment Committee of its respective 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 maturity investments. We have investment
policy guidelines with respect to purchasing fixed maturity investments for our insurance subsidiaries which
preclude investments in bonds that are rated below investment grade by a recognized rating service. 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, 2007 and 2006, our bond portfolio had a fair value that totaled
$1,745.4 million and $1,647.4 million, respectively.

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 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

13

limit. Generally, investments in equity securities are selected based on their potential for appreciation as well as
ability to continue paying dividends. See Item 7 of this Form 10-K, “Management’s Discussion and Analysis of
Financial Condition and Results of Operations—2007 Compared to 2006—Investment Operations Segment—
Market Risks,” for a discussion regarding the market risks related to our investment portfolio.

At December 31, 2007 and 2006, our equity portfolio was classified as available-for-sale and carried at fair

value totaling $254.2 million and $284.2 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” in Item 1A of this 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, 2008, we had 2,185 employees. Our employees are not covered by any collective

bargaining agreement. We consider the relationship with our employees to be excellent.

Item 1A. Risk Factors

Statements contained in this Form 10-K may be “forward-looking” within the meaning of the Section 21E
of the Exchange Act. 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 factors, among others, in
some cases have affected, and in the future could affect, our actual financial 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 AND GEOGRAPHIC CONCENTRATIONS

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, allied lines and commercial multi-
peril coverages. The geographic distribution of our business subjects us to catastrophe exposure from tornadoes,

16

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. See “Narrative Description of Business—
Regulation” in Item 1 of this Form 10-K for a discussion regarding our recent personal lines action with respect
to Florida. 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: 2007 with losses that occurred from hailstorms and windstorms in the
Midwest resulting in approximately $10.8 million in pre-tax losses; 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.

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 AND PRICING

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 use of modeling tools to assist with correctly and consistently achieving the intended results in
underwriting and pricing;

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

our ability to secure regulatory approval of premium rates on an adequate and timely basis;

our ability to predict policyholder retention accurately;

unanticipated court decisions, legislation or regulatory action;

17

•

•

•

•

•

•

•

unanticipated changes in our claim settlement practices;

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

changes in the medical sector of the economy;

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

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

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

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

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

REINSURANCE

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

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

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. While we may adjust prices during
periods of intense competition, it remains our strategy to allow for acceptable profit levels and to decline
coverage in situations where pricing or risk would not result in acceptable returns. Accordingly, our commercial
lines business tends to contract during periods of severe competition and price declines and expand when market
pricing allows an acceptable return.

The personal lines businesses are characterized by an auto underwriting cycle of loss cost trends. Driving
patterns, inflation in the cost of auto repairs and medical care and increasing litigation of liability claims are

18

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. Use of this distribution system
may constrain our ability to grow at a comparable pace to our competitors that utilize multiple distribution
channels. In addition, consumers may prefer to purchase insurance products through alternative channels,
such as through the internet, rather than through agents.

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 86 years. However, we recognize that
although the number of distribution locations has expanded, 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 progressively more difficult to expand the number of
independent agencies representing us. If we are unsuccessful in maintaining and increasing the number of
agencies in our independent agency distribution system, our sales and results of operations could be adversely
affected.

The agents that market and sell our products also sell products of our competitors. These agents may
recommend our competitors’ products over our products or may stop selling our products altogether. Our strategy
of not pursuing market share at prices that are not expected to produce an underwriting profit can have the effect
of making top line growth more difficult. When price competition is intense, this effect is exaggerated by the fact
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 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.

In addition, consumers are increasingly using the internet and other alternative channels to purchase
insurance products. While our website provides a significant amount of information about our insurance
products, consumers cannot purchase insurance through our website. Instead, consumers must contact one of our
independent agents in order to purchase any of our insurance products or make changes to their existing policies.
This sole distribution system may place us at a disadvantage with consumers who prefer to purchase insurance
products online or through other alternative distributions channels.

We also expect

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 could 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
relates to authorization for lines of business, capital and surplus requirements,
limitations,
underwriting limitations,
transactions with affiliates, dividend limitations, (See “Narrative Description of
Business-Regulation-Dividends” in Item 1), 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.

investment

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, in 2007, Florida enacted legislation that
required us to charge rates for homeowners insurance that we believed were inadequate to cover the related
underwriting risk. After careful analysis of this legislation, we concluded that we could no longer operate our
personal lines on a profitable basis in that state. Accordingly, during the second quarter 2007, we filed an
application with the Florida Department of Insurance to withdraw from this state’s personal lines insurance
market effective January 1, 2008. Non-renewals on our personal lines business are in process. We will continue
to write commercial lines business in Florida.

Nearly all states require licensed insurers to participate in guaranty funds through assessments covering a
portion of insurance claims against impaired or insolvent insurers. An increase in the magnitude of impaired
companies could result in an increase in our share of such assessments. Residual market or pooling arrangements
exist in many states to provide certain types of insurance coverage to those that are otherwise unable to find
private insurers willing to insure them. Licensed insurers voluntarily writing such coverage are required to
participate in these residual markets or pooling mechanisms. Such participation exposes the Company to possible
assessments. The potential availability of recoupments or premium rate increases, if applicable, may not offset
such assessments in the financial statements nor do so in the same fiscal periods.

Many of the states in which we operate have passed or are considering legislation restricting or banning 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.

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 taxation, can significantly impact the insurance industry and us.

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.

20

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. An example would be a trend of plaintiffs targeting property and casualty insurers,
including us, in purported class action litigation relating to claim-handling and other practices. 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. In December 2007, the United States Congress extended the
Terrorism Acts through December 31, 2014, and made some modest changes to the Terrorism Acts. We are
evaluating these changes to the Terrorism Act and are taking actions to comply. 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™.

21

While this represents a significant commitment of resources over the next 6 to 24 months, we believe it is
vitally important to our ability to maintain our prospects in business lines. Such automation was successfully put
into production for businessowners products during the latter part of 2007. We expect to introduce such
automation for commercial auto coverage during 2008, to be followed by development of this technology for
workers compensation products. 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.

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 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. Individual securities in our fixed-
income portfolio are subject to credit risk. Downgrades in the credit ratings of fixed maturities can have a
significant negative effect of the market valuation of such securities.

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, our investments 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.

22

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
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
there is no assurance that core business
operations and addresses multiple business interruption events,
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 or affiliated with other insurance
companies, such as the MIGI Insurers, Milbank, Farmers, SA Wisconsin, and most recently the Beacon and
Patrons Groups. It is anticipated that we and State Auto Mutual will continue to pursue acquisitions or affiliations
of other insurance companies in the future.

Acquisitions and affiliations involve numerous risks and uncertainties, such as:

•

•

•

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

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

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

23

•

•

•

•

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

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

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

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

In addition, other companies in the insurance industry have similar acquisition and affiliation strategies.
Competition for target companies or businesses may intensify or we may not be able to complete such
acquisitions or affiliations on terms and conditions acceptable to us. Additionally, the costs of unsuccessful
acquisition and affiliation 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
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, 2007, our parent company owned approximately 64% 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.

24

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.

The increased transparency that arises from information available from the use of tools such as comparative
rater software, could work to our disadvantage. We may have difficulty differentiating our products or becoming
among the lowest cost providers. Expense efficiencies are important to maintaining and increasing our growth
and profitability. If we are unable to realize future expense efficiencies, it could affect our ability to establish
competitive pricing and could have a negative effect on new business growth and retention of existing
policyholders.

VOLATILITY OF OUR COMMON STOCK

The price of our common stock could be volatile.

limited to,

The trading price of our common stock may fluctuate substantially due to a variety of factors, certain of
which may not be related to our operating performance and are beyond our control. Such factors include, but are
not
the following: variations in our actual or anticipated operating results or changes in the
expectations of financial market analysts; investor perceptions of our Company and/or the property and casualty
industry; market conditions in the insurance industry and any significant volatility in the market; and major
catastrophic events.

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

Capitalized terms used in this Item 7 and not otherwise defined have the meanings ascribed to such terms
under the caption “Important Defined Terms Used in this Form 10-K” which immediately precedes Part I of this
Form 10-K.

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 markets a broad line of property and
casualty insurance products through independent agencies in 33 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 64% of State Auto Financial’s outstanding common shares.

State Auto P&C, Milbank, Farmers and SA Ohio (“STFC Pooled Companies”) participate in a quota share
reinsurance pooling arrangement (the “Pooling Arrangement”) with State Auto Mutual, SA Florida, SA
Wisconsin, Meridian Security and Meridian Citizens Mutual, which together with STFC Pooled Companies are
referred to as the “Pooled 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, which is not included
in the Pooling Arrangement, provides nonstandard personal automobile insurance. Our Pooled Companies and
SA National are rated A+ (Superior) by the A.M. Best Company.

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 2001. In general, the Pooling Arrangement covers all the
property and casualty insurance written by the Pooled Companies except State Auto Mutual’s voluntary assumed
reinsurance, middle market business insurance written by State Auto Mutual and Meridian Security and
intercompany catastrophe reinsurance written by State Auto P&C.

As of January 1, 2005, the Pooling Arrangement was modified to add Meridian Security and Meridian
Citizens Mutual as participants. In conjunction with this modification, the STFC Pooled Companies received
$54.0 million in cash from these two companies which related to the additional net insurance liabilities assumed
on January 1, 2005.

As of January 1, 2008, the Pooling Arrangement was further modified to add Patrons Mutual, Litchfield and
Beacon National as participants and to include the middle market business insurance written by State Auto
Mutual and Meridian Security. Concurrently with the addition of Patrons Mutual, Litchfield and Beacon
National, the participating percentages of certain participants were adjusted as presented in the table below;
however the STFC Pooled Companies continue to maintain an overall share of the pool at 80% and State Auto
Mutual and its subsidiaries and affiliates continue to maintain 20%. In conjunction with this modification, the
STFC Pooled Companies will receive approximately $92.0 million in cash from State Auto Mutual and its
subsidiaries and affiliates.

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
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.

For both our personal and business 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.

Losses and Expenses

Our GAAP loss and LAE ratios 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 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.

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 GAAP loss and LAE ratio for the years 2006 and 2005,

Time period is for the year ended December 31, except for 2008, which is as of January 1, 2008.

The remainder of this discussion refers to the Pooling Arrangement in effect prior to January 1, 2008, unless

otherwise noted.

Prior to January 1, 2007, we operated in two significant reportable segments, a standard segment and a
nonstandard segment. In 2006, 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. We established integrated personal and business insurance
teams with product, profit and production responsibilities for their respective areas. Consequently, beginning
insurance, business insurance
with first quarter 2007, our significant reportable segments are personal
(collectively the “insurance segments” or “our insurance segments”) and investment operations, and we have
begun reporting to our principal operating decision makers on these bases, analyzing each segment separately, to
support our risk-based pricing focus.

We evaluate the performance of our insurance segments using industry financial measurements determined
based on Statutory Accounting Principles (“SAP”), which include loss and loss adjustment expense ratios,
underwriting expense ratios, combined ratios, statutory underwriting gain (loss), net premiums earned and net
written premiums. One of the most significant differences between SAP and Generally Accepted Accounting
Principles (“GAAP”) is that SAP requires all underwriting expenses to be expensed immediately and not deferred
over the same period the premium is earned. We evaluate our investment operations segment based on
investment returns of assets. Financial information about our segments for 2007 is set forth in Note 15 to our
Consolidated Financial Statements included in Item 8 of this Form 10-K. Prior period segment information has
been restated to conform to current period presentation.

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

30

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 insure personal and small-to-medium business risks while adhering to disciplined and consistent
underwriting principles through all market cycles.

Our underwriting 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 an underwriting profit
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 agents by stressing the strengths we bring to the marketplace. These strengths include
stability, financial soundness, prompt and fair claims service, and technology which make it easier for
the agent to do business with the State Auto Group and provide substantial value to our customers. We
carefully monitor writing insurance in states that we believe present difficult legislative, judicial and/or
regulatory environments for the insurance industry.

Investment Strategy: We have a disciplined approach to our investment strategy that emphasizes the
quality of our fixed maturity portfolio, which comprised 86% of our total portfolio at fair value at
December 31, 2007, and includes only investment grade securities. During the last year our strategy
has included increasing our positions in tax-exempt fixed maturities in an effort to maximize after tax
investment income in conjunction with diversifying into additional asset classes, such as treasury
inflation protected securities. Our only investments in asset-backed securities are in federal agency
pools and government guaranteed GNMAs. Our internally managed equity portfolio, which comprised
approximately 13% at fair value of our total portfolio at December 31, 2007, emphasizes large-cap,
dividend-paying companies selected based upon their potential for appreciation as well as ability to
continue paying dividends. During the fourth quarter, 2007, we began to diversify our equity portfolio,
and utilize outside managers to invest in U.S. small-cap equities and international instruments. By
diversifying, we hope to achieve a greater total return with reduced volatility.

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.

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

31

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 33 states as of January 1, 2008. As we begin 2008, the
concentration of our direct 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 approximately 17% at
January 1, 2008. Our underwriting guidelines are designed to limit exposures to high risk insurance
matters such as asbestos and environmental claims. Our catastrophe management strategies are
designed to mitigate our exposure to earthquakes and hurricanes.

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). In 2007, we established claims catastrophe teams to enhance our response
to policyholders in catastrophe loss situations.

Independent Insurance Agent Network: We offer our products through over 3,000 agencies in 33
states. We believe the success of our independent
insurance agent network, which is our only
distribution channel, grows out of our commitment to promote and foster close working relationships
with our agents. We seek relationships with agencies where we will be one of their top three insurers,
measured on the basis of direct premiums written, for the type of business we desire. Our agents’
compensation package includes competitive commission rates and other sales inducements designed to
maintain and enhance relationships with existing independent agents as well as to attract new
independent agents. We provide our agents with a co-operative advertising program, sales training
programs, contingent commissions, travel incentives and agency recognition. We continually monitor
our agencies for compatibility with us, taking into account factors such as loss ratio, premium volume,
business profiles and relationship history. This allows us to be proactive in helping our agents grow
their book of business with us profitably and, thus, enhance the long-term value of our relationship.
Our senior management meets frequently with agents to encourage mutual growth and demonstrate our
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 technology efforts are focused on making us as efficient and effective as possible. In
2007, our personal insurance segment technology leveraged past successes with our netXpress™
agency portal by putting emphasis on the integration between various third party technologies and
netXpress™. One such example was adding functionality to “bridge” data directly into our netXpress™
portal from comparative rating tools thus eliminating the re-keying effort and increasing the data
quality level. Agency personnel have welcomed this functionality and rewarded us with increased
quote opportunities and submissions. It has also positioned us to be more effective on book rollover
opportunities. Other integration examples include agency management systems and services that
dynamically order underwriting products like motor vehicle reports, credit reports, and geographic data
used in our pricing algorithms.

32

Our business insurance segment benefited by the introduction of our bizXpressSM portal. The
bizXpressSM portal was deployed in all of our states of operation (except Florida) in 2007. During the
course of 2007, several disciplines were more effectively used in our technology efforts. Quality
assurance practices were formalized and used resulting in less defects in applications once deployed.
Additionally, more project management rigor and application governance allowed our project delivery
to be more predictable for all business segments. Finally, we implemented performance testing tools
and application monitoring technologies so we can increase our responsiveness and operate our
information systems infrastructure efficiently.

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 in this
Item 7. 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

Our fixed maturity, equity security and certain other invested asset

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 we consider 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 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 “2007 Compared to 2006” and
“2006 Compared to 2005” included in this Item 7.

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, 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.

33

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 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 we use
many internal and external resources, as well as multiple established methodologies to calculate IBNR, there is
no method for determining the exact ultimate liability. For a further discussion regarding our losses and loss
expense reserves and our reserving methods see “Other—Loss and Loss Expense Reserves” included in this
Item 7.

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. We review these factors annually, including the
discount rate and expected long term rate of return on plan assets. Because these obligations are based on
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 in this Item 7.

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.

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.

(1) At December 31, 2006, accumulated comprehensive income was reduced by $63.9 million and book value per share was reduced
by $1.56, respectively, in connection with the initial adoption of SFAS 158 (defined below) at December 31, 2006. For a further
discussion of the impact of SFAS 158, see “Other—Employee Benefit Plans” included in this Item 7.
See “2007 Compared to 2006” section below for definitions.

SAP loss and LAE ratio is statutory losses and loss expenses as a percentage of net earned premium. SAP expense ratio is statutory
underwriting expenses and miscellaneous expenses offset by miscellaneous income (“underwriting expenses”) as a percentage of
net written premiums. SAP combined ratio is the sum of the SAP loss and LAE ratio and the SAP expense ratio.

(4)

(5) We use the statutory net premiums written to surplus ratio because there is no comparable GAAP measure. This ratio, also called

the leverage ratio, measures our statutory surplus available to absorb losses.

2007 Compared to 2006

Income before federal income tax decreased $6.4 million (4.0%) to $155.3 million from 2006. The most
significant factors contributing to this decrease related to a decline in our revenues, specifically our premiums,
and an increase in our loss and loss expenses. Our GAAP loss and loss expense ratio for 2007 was 58.4%
compared to 57.4% in 2006.

Insurance Segments

Insurance industry regulators require our insurance subsidiaries to report their financial condition and results
of operations using SAP. We use SAP financial results, along with industry standard financial measures
determined on a SAP basis and certain measures determined on a GAAP basis, to internally monitor the
performance of our insurance segments and reward our employees. The more common financial measures used
are loss and LAE ratio, underwriting expense ratio, combined ratio, net premiums written and net premiums
earned. The combined ratio is the sum of the loss and LAE ratio and the underwriting expense ratio. When the

35

combined ratio is less than 100%, the insurer is operating at an underwriting gain and when it is greater than
100%, the insurer is operating at an underwriting loss. Underwriting gain (loss) is determined by subtracting
from net earned premiums, losses and loss expenses and underwriting expenses.

One of the more significant differences between GAAP and SAP is that SAP requires all underwriting expenses
to be expensed immediately and not deferred over the same period that the premium is 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 in this Form 10-K. 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). All references to financial measures or
components thereof in this discussion are calculated on a GAAP basis, unless otherwise noted.

Revenue

We measure our top-line growth for our insurance segments based on net written premiums, which represent
the premiums on the 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. 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.

Personal Insurance Segment Revenue

Our personal insurance segment consists primarily of auto (standard and nonstandard) and homeowners’
products, with personal auto representing approximately 40% of our total consolidated net written premium in

36

2007 and 2006. The following table provides a summary of written and earned premium, net of reinsurance, by
major product line of business for our personal insurance segment for the years ended December 31, 2007 and
2006:

In total, the personal insurance segment net written premium increased from 2006 by 0.4%. While a modest
increase, it does represent an improvement from 2006 which declined approximately 3.5% from 2005. In
particular, competition remains intense within the personal auto market, which is contributing to our overall
modest growth. It remains our strategy that rates be risk-based, reflecting the underlying loss and expense trends.

Net written premiums for our standard auto products decreased 0.1% in 2007 compared to 2006. The competitive
marketplace combined with some rate reductions in 2007 contributed to this result. However, we have seen increasing
new business production related to the introduction of our CustomFitSM product into new states. CustomFitSM uses a
multi-variate rating approach that broadens the underwriting eligibility for new customers. In 2007, we began
introducing the second generation of CustomFitSM, which further improves our rating sophistication.

Net written premiums for nonstandard personal auto increased 0.7% in 2007 compared 2006. This
represents a significant improvement compared to the 2006 premium result which declined 13.3% from 2005.
Targeted rate decreases coupled with the introduction of new discounts and an increased marketing effort
contributed to an increased level of new policy submissions leading to an increase in premiums.

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. During 2007, we introduced in
17 states various “real time” comparative rating tools which can be used by our independent agents to prepare
comparative rate quotes from multiple insurance companies by entering the rating information once. We believe
our independent agents will quote and write more personal standard and nonstandard auto with us as a result of a
more efficient quoting process.

Homeowners’ net written premium increased 0.9% in 2007 compared to 2006. In 2007, we introduced a
home purchase discount and expanded our age of dwelling discounts to help attract new business which we
believe contributed favorably to increased new homeowners policy submission levels.

During 2007, we continued to enhance our personal lines point of sale portal, netXpress™, by adding several
new integration options with a variety of third party tools used by our independent agents including a

37

joint credit ordering tool, integrated report ordering, and the comparative rating tools mentioned above. We also
have added a number of internal integration points through the use of web services technology. One example of
this is real time integration with our enterprise billing system to provide accurate installment information via
netXpressTM. The goal of these technology investments is to streamline quoting and policy issuance for our
agents. We strive to be their carrier of choice and ease of doing business is a major driver toward that goal.

We have also focused on improving our policyholders’ ease of doing business with respect to bill payment
and claim reporting and settlement. In 2006, we expanded our premium payment options to include credit and
debit card via www.stateauto.com. In 2007, we deployed an Interactive Voice Response (“IVR”) solution to
accept premium payments over the phone providing yet another option for policyholders. The IVR solution
provides a more efficient business process for our payment services department and is expected to drive better
policy retention results. During 2007, nearly 189,000 payments were made through self-service technologies
such as these representing over $76 million of premium payments.

Additionally, we recently completed several strategic initiatives to enhance our claims handling ability and
better manage major catastrophes. Field claims personnel are now equipped with mobile devices that permit
adjusting property claims at the loss site. We believe that our professional claims service backed by reliable
technology will continue to distinguish us from our competitors.

During the second quarter 2007, we filed an application with the Florida Department of Insurance to
withdraw from the state’s personal lines insurance market effective January 1, 2008. After a careful analysis of
recent regulatory changes in Florida, we concluded that we could no longer operate our personal lines on a
profitable basis in that state. Non-renewals on this business are in process. We will continue to write commercial
lines business in Florida. During 2007, we wrote $12.5 million of personal lines premium in Florida.

Business Insurance Segment Revenue

We focus our business insurance sales on small to medium sized exposures and offer a broad range of both
property and liability coverages such as commercial auto, commercial multi-peril, fire and allied lines, products
liability and workers’ compensation. The following table provides a summary of written and earned premium,

The business insurance segment net written premium for 2007 decreased 0.5% from 2006. Business
insurance continues to be impacted by rate competition and ease of doing business issues. We are seeking to
balance our traditional underwriting discipline with new products and pricing tools that support the production of
profitable new business.

In 2007, we began offering our business products in two new states—Colorado and Texas—and increased

the number of business products offered in Arizona.

We also continue to enhance our back office systems which enable us to more effectively support our
independent agents. We recently implemented the technology to provide real time functionality in our business
insurance policy administration systems for quote and issuance transactions. Also known as straight through
processing (“STP”), our associates are now able to more effectively and accurately handle typical business
insurance processing. The policy service time has been greatly reduced as a result of this new technology.

To make it easier for our agents to submit business insurance accounts, in 2007, we introduced bizXpressSM,
our web-based quote and issuance system, to agents in all of our operating states except Florida. We currently
utilize bizXpressSM for businessowners policies. We are working to expand bizXpressSM functionality to our
business auto products in the first half of 2008, while we develop the same functionality for workers
compensation business for introduction at a later date. This has been a highly collaborative initiative that has
included agent focus group input
lifecycle. It also leverages the STP technology
investment mentioned above. We believe this technology investment should better position us for revenue
growth opportunities in the future and start to drive efficiencies into our business model much like we have seen
in personal insurance.

Losses and Expenses

Our GAAP loss and LAE ratio was 58.4% in 2007 compared to 57.4% in 2006. Loss results for the year
have been mixed. Our core auto (personal and business) and other and product liability lines continue to perform
well. On the property side, catastrophe losses for 2007 were lower than in 2006, but we experienced significantly
higher frequency of large fire losses within our personal and business lines during 2007.

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 GAAP loss and LAE ratio for the years 2007 and 2006, 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 $54.7
million in 2007 came primarily from accident years 2005-2006. The more notable items contributing to the 2007
development are:

•

•

Favorable development at the product level is primarily from the auto liability and other liability lines,
where current loss projections using more mature claim data resulted in lower expected average claim
severities than past projections. The impact
is approximately $23.5 million for these two lines
combined.

Adjusting and other expense reserves accounted for approximately $11.8 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. (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. “Adjusting and other expenses” are
the components of ALAE and ULAE that relate to costs other than defense, litigation, and medical cost
containment.)

• We hold ceded loss reserves in anticipation of transferring liabilities to reinsurers and other pools and
associations. Ceded loss reserves were above previously anticipated levels by approximately $10.0
million. 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
fire, auto liability and workers’ compensation lines.

•

•

Favorable catastrophe loss development of approximately $4.6 million is attributable to the 2006
accident year. This development occurred primarily within our homeowners, other personal and
commercial multi-peril lines of business.

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
developed as of December 31, 2006.

See discussion regarding the 2006 calendar year development at “2006 Compared to 2005—Losses and
Expenses” section included herein. See additional discussion regarding loss and loss expense reserves at the
“Other—Loss and Loss Expense Reserves” section included herein.

Catastrophe losses in 2007 totaled $37.1 million (3.7 loss ratio points) compared to $91.2 million (8.9 loss
ratio points) in 2006. During 2007, our catastrophe losses resulted primarily from wind and hail in several
Midwestern states and mostly impacted our homeowners business. Catastrophe activity in 2006 had a significant
impact on both our personal and business insurance property lines. The discussion of catastrophe losses includes
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.

The personal insurance segment loss ratio was 1.3 points lower in 2007 than in 2006. Catastrophes
accounted for 5.0 loss ratio points in 2007 compared to 11.9 points in 2006 period. Excluding the impact of
catastrophes, the personal lines loss ratio in 2007 was 5.5 points higher than in 2006 period. The increase in both
the standard and nonstandard auto loss ratios can be attributed partially to rate reductions taken in 2006 and
2007. The improvement in the homeowners loss ratio can be attributed primarily to the reduction of catastrophe
losses. In 2007, catastrophes added 14.2 points to the homeowners loss ratio compared to 32.2 points in 2006
period.

The business insurance segment’s loss ratio for 2007 was 4.5 points higher than in 2006. Catastrophes
accounted for 1.6 loss ratio points in 2007 compared to 4.3 points in 2006. Excluding the impact of catastrophes,
the business lines loss ratio in 2007 was 7.2 points higher than in 2006. The overall increase reflects rate
reductions in premium per exposure on business written in 2006 and 2007 and an increase in the number of large
property losses. Workers’ compensation, which represents approximately 9.0% of our business insurance
portfolio and less than 4.0% of our overall insurance segment portfolio, tends to be a more volatile line of
business due to its size and risks written. We do not write mono-line workers’ compensation, but make our
product available as part of the business package policy. The increase in the level of 2007 losses as compared to
2006 was driven largely by an increase in severity rather than frequency. We regularly monitor frequency and

41

severity trends, as well as the overall construction of our workers compensation book of business. In addition, we
promote the writing of the low-hazard risk types that have developed a consistent pattern of profitability.

Acquisition and operating expenses, as a percentage of earned premiums (“GAAP expense ratio”) were
34.4% in 2007 compared to 34.0% in 2006. The 2007 expense ratio was largely impacted by a lower premium
base in 2007 compared to 2006.

Investment Operations Segment

Our investment portfolio and the investment portfolios of State Auto Mutual, and its subsidiaries and
affiliates are managed by our subsidiary, Stateco. The Investment Committee of the Board of Directors of each of
our insurers sets investment policies to be followed by Stateco.

At December 31, 2007, our investments in fixed maturities, equity securities and certain other invested
assets were held as available-for-sale and carried at fair value. The unrealized holding gains or losses, net of
applicable deferred taxes, are included as a separate component of stockholders’ equity as “accumulated other
comprehensive loss” and as such are not included in the determination of net income.

Our primary investment objectives are to generate income, preserve capital and maintain adequate liquidity
for the payment of claims and expenses. Our current investment strategy does not rely on the use of derivative
financial instruments.

We have investment policy guidelines with respect to purchasing fixed maturity investments for our
insurance subsidiaries which preclude investments in bonds that are rated below investment grade by a
recognized rating service. For the insurance subsidiaries, the maximum investment in any single note or bond is
limited to 5.0% or less of statutory assets, other than obligations of the U.S. government or government agencies,
for which there is no limit. Our fixed maturity portfolio is composed of high quality, investment grade issues,
comprised almost entirely of debt issues rated AAA or AA. At December 31, 2007, we had no fixed maturity
investments rated below investment grade. Our only investments in asset-backed securities are in federal agency
pools and government guaranteed GNMAs.

Our internally managed equity portfolio invests in U.S. large-cap, dividend-paying companies across many
different industries selected based upon their potential for appreciation as well as ability to continue paying
dividends. This diversification across companies and industries reduces volatility in the value of the large-cap
equity portfolio. In addition, our investment policy guidelines limit the purchase of a specific stock to no more
than 2% of the market value of the stock at the time of purchase, and no single equity holding should exceed 5%
of the total equity portfolio.

During the fourth quarter 2007, we began to diversify our equity portfolio and utilize outside money
managers to invest in U.S. small-cap equities and international instruments. These managers are permitted to
manage the portfolios according to their own respective portfolio objectives. In selecting our outside money
managers we confirm that their portfolio objectives, including risk tolerance, are acceptable to us; however, there
may be slight differences in their objectives with respect to dividend payments and other constraints that we
apply to our large cap equity holdings. By further diversifying our portfolio into small-cap equities and
international instruments, we hope to achieve a greater total return with reduced volatility.

42

In August 2007, we completed a portfolio diversification study with the objective to reduce the volatility of
the returns and improve our overall after-tax return while continuing to maintain a high-quality portfolio. Based
on this study, the Committee (defined below) approved the following target asset allocation:

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.

At December 31, 2007, our equity portfolio consisted of approximately 80 different large-cap stocks and
325 small-cap stocks. The largest single position was 3.2% of the equity portfolio based on fair value and the top
ten positions were equal to approximately 25.1% of the equity portfolio.

Our equity portfolio consists primarily of large-cap, value-oriented stocks with a small allocation to
small-cap equities. Therefore, when large-cap stocks and/or value-oriented stocks perform well our equity
portfolio typically performs well compared to benchmarks. Conversely, when growth stocks outperform value
and/or small- to mid-cap stocks outperform large-cap stocks, our equity portfolio does not perform as well
compared to benchmarks. This is due to the significant overweighting in large-cap, value-oriented stocks versus
small-cap and growth stocks in the portfolio.

In 2005, the Investment Committee of State Auto Financial’s Board of Directors (“the Committee”)
approved a targeted allocation of 70% tax-exempt fixed maturities, 15% taxable fixed maturities and 15%
equities. This reallocation effort would result in lower pre-tax investment yields but higher after tax investment
income than if we had continued under the then current allocation percentages.

In November 2006, the Committee approved a $50.0 million repositioning of the then-current taxable and
tax-exempt holdings to reach our targeted percentage at a quicker pace than if we just used new monies. Based

44

on this action, the sale of approximately $50.0 million of taxable securities was completed by December 31,
2006. Reinvestment into tax-exempt securities of the proceeds from these actions was completed during the first
quarter 2007.

During the Committee’s March 2007 meeting, the allocation status was reviewed and the Committee
approved an additional $100.0 million repositioning of the then-current taxable and tax-exempt holdings. Based
on this action, the sale of approximately $100.0 million of taxable securities was completed by March 31, 2007.
Reinvestment into tax-exempt securities of the proceeds from these actions was completed during the 2007
second quarter. After completion of the targeted rebalancing, we assessed the securities held and confirmed our
intent to hold the remaining securities until either recovery of fair value or maturity.

Market Risk

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 instruments; (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 maturity 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 maturity 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 maturity portfolio. The duration of the fixed maturity portfolio was
approximately 5.10 and 5.35 as of December 31, 2007 and 2006, 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 maturity
portfolio (excluding other debt securities) as of December 31, 2007:

This table summarizes only the effects that a parallel change in interest rates could have on the fixed
maturity 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 maturity 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 maturity values may
differ significantly from what is shown in the table.

We believe that the fixed maturity portfolio’s exposure to credit risk is minimal as greater than 94% of the
bonds we own are rated AA or better and the remaining bonds are rated A. 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 maturity 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. We have no asset-backed securities in our fixed
maturity portfolio which may be labeled sub-prime mortgage-backed securities. We only invest in conventional
mortgage backed securities issued by a federal agency or that are U.S. Government guaranteed. Specifically, our
only investment in asset-backed securities (approximately $189.4 million or 9.4% of our available-for-sale

45

investment portfolio) are in federal agency pool and government guaranteed GNMAs, of which 63.8% are
GNMAs, which are guaranteed by the full faith and credit of the U.S. Government.

Our fixed maturity investment portfolio at December 31, 2007 included securities issued by numerous
municipalities with a total carrying value of $1,452.0 million. Approximately $829.4 million or 57% of these
securities were enhanced by third-party insurance (the “Credit Enhancement”) for the payment of principal and
interest in the event of an issuer default. Such insurance generally results in a rating of “AAA” being assigned by
independent ratings agencies to those securities. The downgrade of credit ratings of insurers of these securities
could result in a corresponding downgrade in the ratings of the securities from “AAA” to the underlying rating of
the respective security without giving effect to the benefit of the Credit Enhancement. Credit Enhancement is not
a primary consideration to us when purchasing a municipality security as we consider the underlying credit rating
of the security by Moody’s and S&P as a more important factor in our evaluation process. Of the total $829
million of insured municipal securities in our investment portfolio, approximately 82% were rated AA or better,
without the benefit of a Credit Enhancement. We do not believe that a loss of a Credit Enhancement would have
a material adverse impact on our results of operations, financial position or liquidity, due to the underlying
strength of the issuers of the securities, as well as our ability and intent to hold the securities.

As of December 31, 2007, our large-cap equity portfolio had a beta of 0.99 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 large-cap 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 directly 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.

Investment Operations Revenue

Net investment income for 2007 was $84.7 million compared to $83.1 million in 2006. In 2007 our average
invested assets increased due to our insurance segments’ favorable underwriting cash flows. However, our
pre-tax return on investments declined slightly as provided in the table below due largely to rebalancing our fixed
maturity portfolio as described above toward tax-exempt bonds, which have a lower yield on a pre-tax basis.
After tax, our net investment income for 2007 was $73.6 million (13.2% effective tax rate) compared to $69.8
million (16.1% effective tax rate) for 2006.

Most of the realized gains in 2007 were derived from the equity segment of the portfolio. Equity sales were
executed for various reasons, including the achievement of our price target and raising funds within two of our
insurance subsidiaries to fund cash dividends to State Auto Financial. (See “Other Capital Transactions” section
below.) The realized gains on the fixed maturity portfolio were achieved by selling shorter-term tax-exempt
securities and subsequently reinvesting those funds into longer-term tax-exempt securities as well as selling
taxable securities to reinvest the proceeds into the tax-exempt securities as described above. For the year ended
December 31, 2007, realized losses of $1.3 million on the fixed maturities related primarily to selling taxable
securities to support our shift into tax-exempt securities. Realized losses of $7.1 million on equity securities
related primarily to the sale of equity positions where changes in government policy or business conditions, in
our opinion, greatly diminished future business prospects.

We regularly monitor our investment portfolio for declines in value that are other-than-temporary, an
assessment which requires significant management judgment. Among the factors considered by management 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.

For the year ended December 31, 2007, we recognized $1.9 million other-than-temporary impairments
compared to $5.4 million for the same 2006 period. During 2007 we recognized no other-than-temporary
impairments on our fixed maturity portfolio; however, we recognized $1.9 million in realized losses related to
other-than-temporary impairments within our equity portfolio. Of the $1.9 million in realized losses, $1.1 million
related to two equity positions within the consumer cyclical sector impacted by the downturn in the housing
industry. The remaining $0.8 million in realized losses was limited to our externally managed U.S. small cap
portfolio for which we were unable to make the assertion regarding our intent to hold particular securities that
were currently valued below cost until recovery in the near term. The other-than-temporary impairments
recognized in 2007 were limited to these securities, based on specific facts and judgments related to these
particular issuers. The 2006 write-downs related primarily to our investment in certain subordinate income notes
and principal protected units representing purchased beneficial interests in securitized financial assets. We
reduced the estimate of future cash flows we expected to receive from these securities in light of actual default
rates of the underlying collateral securities exceeding the assumed defaults.

Gross Unrealized Investment Gains and Losses

A review of our investment portfolio at December 31, 2007 determined there were no individual
investments with an unrealized loss that had a fair value significantly below cost continually for more than one
year. There were also no individual material securities with an unrealized holding loss at December 31, 2007.

Other Income Statement Items

Interest expense on our debt was $7.6 million and $7.4 million for the years ended December 31, 2007 and

2006, respectively.

Our 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 the year ended December 31, 2007, the effective tax rate was 23.3% compared to
25.5% for the same 2006 period. As previously discussed, the effective tax rate on net investment income
declined to 13.2% for 2007 versus 16.1% for 2006.

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. 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.

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
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 lines market 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.

Net written premiums in nonstandard personal auto decreased $6.5 million (13.3%) in 2006. However,
nonstandard personal auto 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.

The personal auto market appears to be 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.

50

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.

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.

$71.7

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 $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
average claim severities than past projections. The impact
is $24.7 million for these two lines
combined.

Adjusting and other expense reserves 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
developed as of December 31, 2005.

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.

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
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 Consolidated Statements of Income.

54

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.

The GAAP expense ratio was 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 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.

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

55

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.

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.

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

Investment Operations Revenue

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.

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 insurance subsidiaries 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.

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 maturity
portfolio were achieved by selling shorter-term municipal bonds and subsequently reinvesting those funds into
longer term municipal bonds.

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.

Gross Unrealized Investment Gains and Losses

A review of our investment portfolio at December 31, 2006 determined there were no individual
investments with an unrealized holding loss that had a fair value significantly below cost continually for more
than one year. There were also no individual material securities with an unrealized holding loss at December 31,
2006.

Other Income Statement Items

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 in this
Item 7.

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.

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, as well as funds available under our
Credit Facility (as defined below). 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

58

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, 2007 and 2006, we had
$70.9 million and $73.4 million, respectively, in cash and cash equivalents, and $2,019.9 million and $1,936.1
million, respectively, of total available-for-sale investments at fair value. In addition, substantially all of our
fixed maturity and equity securities are traded on public markets. For a further discussion regarding investments
see “Investments Operations Segment” included in this Item 7.

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 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. 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.

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. 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 in this Item 7.

Net cash provided by operating activities was $121.7 million, $93.5 million and $226.9 million for 2007,
2006 and 2005, 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. Cash from operations in 2007
increased $28.2 million over 2006 primarily due to a reduction in claim payments from a lower level of
catastrophe losses in 2007 compared to 2006 offset partially by an increase in taxes paid. 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 by the STFC Pooled Companies in
connection with adding Meridian Security and Meridian Citizens Mutual to the Pooling Arrangement. 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.

59

During 2007, 2006 and 2005, as permitted by regulations of the Internal Revenue Service, we made cash
contributions of $11.5 million, $10.0 million and $7.5 million, respectively, to our defined benefit pension plan
on behalf of our employees. The actuarially determined contribution to our defined benefit 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
our defined benefit pension plan of approximately $12.0 million during 2008. For a further discussion regarding
our defined benefit pension plan see “Employee Benefit Plans” included in this Item 7.

Net cash used in investing activities was $86.1 million, $43.2 million and $212.5 million for 2007, 2006 and

2005, respectively.

The increase in 2007 versus 2006 is principally the result of:

•

•

a greater amount of cash and cash equivalents available to invest at the beginning of 2007 versus 2006
($73.4 million in 2007 compared to $28.7 million in 2006);

an increase in the level of cash provided from operations between the two years.

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 in connection with adding Meridian Security
and Meridian Citizens Mutual to the Pooling Arrangement; and

a decline in the 2006 level of cash provided by operating activities as described above.

Our financing activities for 2007, 2006 and 2005 produced net cash outflows of $38.0 million, $5.6 million,

and $50.0 million, respectively. The following contributed to the fluctuations between years:

•

•

•

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

Dividends paid to shareholders totaled $20.5 million, $15.4 million and $8.6 million for 2007, 2006
and 2005, respectively.

$22.1 million in cash used to repurchase common shares under our stock repurchase program. See
“Other Capital Transactions” below.

The increase in dividends paid 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 $13.2 million, $12.4 million and $2.4 million in dividends for
2007, 2006 and 2005, respectively; and

Dividends paid per common share have increased over the three year period: $0.50 in 2007; $0.38 in
2006 and $0.27 in 2005.

Other Capital Transactions

On August 17, 2007, State Auto Financial’s Board of Directors authorized the repurchase, from time to
time, of up to 4.0 million of its common shares, or approximately 10% of State Auto Financial’s outstanding
shares, over a period extending to and through December 31, 2009. State Auto Financial will repurchase shares
from State Auto Mutual in amounts that are proportional to the respective current ownership percentages of State

60

Auto Mutual, which is approximately 64%, and other shareholders. Our total share repurchase activity in 2007
was 0.8 million common shares at an average repurchase price of $27.21 per share for a total of $22.1 million.

On March 7, 2008, the Board of Directors of State Auto Financial declared a quarterly cash dividend of
$0.15 per common share, payable on March 31, 2008, to stockholders of record on March 17, 2008. This is the
67th 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 fifteen
consecutive years.

To fund these capital transactions and provide additional working capital to State Auto Financial, on
September 12, 2007, State Auto P&C and Milbank declared cash dividends of $40.0 million and $10.0 million,
respectively, to State Auto Financial. The cash transfer of dividends was completed in October 2007.

Other Events

On February 14, 2008, we issued a press release announcing preliminary estimates of 2008 catastrophe
storm activity through February 8, 2008. This press release disclosed our expectation that first quarter 2008
earnings will include between $32.0 and $36.0 million in pre-tax catastrophe losses related to unusual January
and early February storm activity. Severe wind and tornado activity which impacted the Midwest during the first
five weeks of this year are expected to contribute significantly more losses to our first quarter 2008 results than
are normal. Over the past five years, we have experienced an average of $6.7 million in catastrophe losses during
the first quarter. We reported $8.1 million in catastrophe losses for the first quarter of 2007. While the
2008 January and February catastrophe storm losses will be significant to our first quarter results, we do not
expect these losses to have a significant impact on our overall financial position.

Borrowing Arrangements

The following provides an overview of our borrowing arrangements during 2007 and outstanding at

December 31, 2007:

Credit Agreement

Through July 12, 2007, State Auto Financial had a credit agreement with a syndicate of lenders which
provided for a $100.0 million five-year unsecured revolving credit facility. State Auto Financial did not borrow
any funds under the credit facility.

On July 12, 2007, State Auto Financial terminated its then-current credit agreement and entered into a new
credit agreement (“Credit Agreement”) with a syndicate of lenders which provides for a $200.0 million five-year
unsecured revolving credit facility (“Credit Facility”). During the term of the Credit Facility, we have the right to
increase the total facility to a maximum total facility amount of $250.0 million, provided that no event of default
has occurred and is continuing. While the Credit Facility will be available for general corporate purposes,
including working capital, acquisitions and liquidity purposes, we presently intend to keep $100.0 million of the
Credit 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 in this Item 7. The Credit Facility provides for interest-only payments during its
term, with principal due in full at maturity. Interest is based on either a London interbank market rate or a base
rate plus a calculated margin amount. The Credit Agreement contains certain covenants, including financial
covenants that require us to maintain a minimum net worth and not exceed a certain debt to capitalization ratio.
As of December 31, 2007, State Auto Financial had not made any borrowings and was in compliance with all of
the covenants under the Credit Agreement.

61

Senior Notes

In 2003, State Auto Financial 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, 2007, we were in compliance with all covenants related to the Senior Notes.

Trust Securities

State Auto Financial’s Delaware business trust subsidiary (the “Capital Trust”) issued $15.0 million
liquidation amount of capital securities in 2003, due 2033. In connection with the Capital Trust’s issuance of the
capital securities and the related purchase by State Auto Financial of all of the Capital Trust’s common securities
(liquidation amount of $0.5 million), State Auto Financial 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 January
2005 through December 31, 2007 ranged from 8.61% to 9.78%.

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
in this Item 7. Based upon the notes payable carrying value at December 31, 2007, we had $15.5 million notes
payable with variable interest and $102.5 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.

During 2007, the Beacon Group was added to the State Auto Group’s reinsurance programs described below

and as of January 1, 2008, the Patrons Group was added to these reinsurance programs.

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, 2007, so that reinsurers became responsible for 100% of a covered loss in excess of $2.0
million, up to $5.0 million of covered loss, compared to 95% 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.

Under our property per risk excess of loss program, each company within the our State Auto Group is
responsible for the first $3.0 million of each covered loss and reinsurers are responsible for 100% of the excess
over the retention up to $20.0 million of covered losses. The rates for this reinsurance are negotiated annually.

Under our property catastrophe excess of loss program, the State Auto Group retains the first $55.0 million
of catastrophe loss per occurrence. Outside reinsures 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. The coverage attaches at $135.0 million of catastrophe loss
per occurrence. 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. The State Auto Group
does not currently intend to renew this intercompany catastrophe reinsurance arrangement upon its expiration on
July 1, 2008. The State Auto Group is considering other alternatives, which include securing replacement
coverage from a third party reinsurer or relying upon the $100.0 million set aside under the Credit Agreement,
discussed above, to fund this layer of catastrophe reinsurance.

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. 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 and certain companies. 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.
(Facultative reinsurance provides for a separate reinsurance agreement that is negotiated for a particular risk or
insurance policy.)

(1) We derived expected payment patterns separately for the direct loss and ALAE reserves. Amounts included the STFC Pooled
Companies net additional share of transactions assumed from State Auto Mutual through the Pooling Arrangement. For a
reconciliation of management’s best estimate see “Loss and Loss Expense Reserves” included in this Item 7. These patterns were
applied to the December 31, 2007, loss and ALAE payable to generate estimated annual incremental loss and ALAE payments for
each subsequent calendar year. These amounts are based on historical payment patterns and do not represent actual contractual
obligations. The actual payment amounts and the related timing of those payments could differ significantly from these estimates.
For a discussion of these debt instruments, see “Liquidity and Capital Resources—Borrowing Arrangements” included in this
Item 7.
The Senior Notes bear interest at a fixed rate of 6.25% per annum, which is payable each May 15 and November 15.
Interest on the subordinated debentures was calculated using an interest rate equal to the three-month LIBOR rate at December
31, 2007 of 4.7025% plus 4.20%, or 8.9025%.
These amounts are estimates of ERISA minimum funding levels for our defined benefit pension plan and do not represent an
estimate of our expected contributions. See Note 9, “Pension and Postretirement Benefits Plans” to our Consolidated Financial
Statements included in Item 8 of this Form 10-K for a tabular presentation of expected benefit payments from the State Auto
Group’s defined benefit pension plan.

Regulatory Considerations

At December 31, 2007, 2006 and 2005, 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

64

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, 2007, 2006 and 2005 were as

follows:

(1) We use the statutory leverage ratio as there is no comparable GAAP measure.

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. Under current law, at December 31, 2007, after adjustment for dividend payments made in the previous
twelve month period, a total of $79.6 million is available in 2008 for payment as a dividend from our insurance
subsidiaries to State Auto Financial, without prior approval from our respective domiciliary state insurance
departments. In 2007, 2006, and 2005, State Auto Financial received $50 million, $0, and $40.5 million in
dividends from its insurance subsidiaries, 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, 2007, the ratio of
total adjusted statutory capital to authorized control level of State Auto Financial’s insurance subsidiaries ranged
from 969% to 1,859%.

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, 2007, our
A.M. Best, Moody’s and Standard & Poor’s ratings were assigned stable outlooks.

OTHER

Employee Benefit Plans

The State Auto Group has a defined benefit 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,
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.

including changes in investment returns and interest rates,

To calculate the State Auto Group’s December 31, 2007 pension projected benefit obligation (“PBO”) we
used a discount rate of 6.25% based on an evaluation of the expected future benefit cash flows of our defined
benefit 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, 2007, a discount rate of 6.0% and an expected long-
term rate of return on plan assets of 9.0% were used.

66

The selected discount rate of 6.25% increased 0.25 points from the 6.00% rate used in 2006 which had the
effect of decreasing the 2007 PBO and related unrecognized net actuarial loss by approximately $7.8 million.
Cumulative unrecognized actuarial losses of approximately $62.6 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 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, 2007, the ABO and PBO were $194.3 million and $217.3 million,
respectively. At December 31, 2007 the fair value of the assets of our defined benefit pension plan was $220.0
million, which resulted in an overfunding status within our balance sheet of $2.7 million. The State Auto Group
has consistently targeted contributions to our defined benefit 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.

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 2007 benefit obligation for our health
care plan, we increased our selected discount rate by 0.25 points to 6.25% from the 2006 discount rate to match
the anticipated stream of future benefit payments. 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 2007 the expected rate of increase in future health care costs
was 10% for 2007, trending down 1% per year to 5% thereafter. The change in the discount rate and adjustment
for the assumed health care cost trend rate had the effect of increasing the benefit obligation and related
unrecognized net actuarial loss by approximately $0.6 million. The benefit obligation under our health care plan
was $123.0 million at December 31, 2007 which exceeded the fair value of plan assets of $2.3 million, resulting
in an underfunding status of $120.7 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 ending 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.

67

•

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 following table provides the incremental effects of adopting the provisions of SFAS 158 on our balance
sheet at December 31, 2006. The adoption of SFAS 158 had no effect on our consolidated statement of income
for the year ended December 31, 2006, or for any prior period presented.

With regard to the adoption of the new measurement guidelines, we are continuing to review the transition
alternatives available to us but intend to adopt the required December 31 measurement at December 31, 2008.
The adoption of SFAS 158 did not have an impact on our debt covenants.

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
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.

68

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
legal developments, storm loss estimates, and economic
historical and statistical
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 and 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 Method uses 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.

Claim Counts and Severities Method: 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

69

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. The primary
determinant in estimating the reserve range boundaries are the variances measured within the historical reserving
data for the various lines of business. Property lines typically have smaller variances, while liability lines can
experience significant variability. MBE of loss reserves considers the 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, 2007 was $697.5 million, within a projected range of
$640.6 million to $714.1 million. (These values presented are on a direct basis, gross of salvage and subrogation
recoverable, and before reinsurance, except for the STFC Pooled Companies’ participation in the inter-company
Pooling Arrangement. Therefore, these values cannot be compared to many of the 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 $714.1 million, the

70

reserve increase of $16.5 million is an after-tax decrease of $10.7 million on net income. Likewise, should losses
decline to the low end of $640.6 million, the $57.0 million reserve decrease would add $37.0 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, 2007, 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
$54.2 million on reserves, or a $35.3 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”). Based on historical patterns, selected ratios of paid
ULAE to paid losses are 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 incurred when the claim is open, and the other 50% are incurred when the claim is closed, 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, 2007 decreased $13.9 million (2.1%) from 2006 due

to a combination of the following:

•

•

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

At the end of 2006, catastrophe loss reserves, primarily on homeowners and commercial multi- peril
lines, remained in reserve status, but were paid during 2007 resulting in some of the reserve decreases.

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 $3.2 million, and
environmental reserves are $7.9 million, for a total of $11.1 million, or 1.7% of net losses and loss expenses
payable. Our environmental reserves increased approximately $1.2 million from 2006 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. For an additional discussion relating
to losses and loss expense reserves see “Impact of Significant External Factors”, included in this Item 7.

New Accounting Standards:

Adoption of Recent Accounting Pronouncements

In September 2006,

issued SFAS No. 158,
the Financial Accounting Standards Board (“FASB”)
“Employers’ Accounting for Defined Benefit Pension and Other Postretirement Plans, an amendment of FASB
Statements No. 87, 88, 106, and 132(R)” (“SFAS 158”) that requires employers with 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 ending
after December 15, 2008. On December 31, 2006, the Company adopted the recognition and disclosure
provisions of SFAS 158, which had no effect on the Company’s consolidated statement of income for year ended
December 31, 2006, or for any prior period presented in the 2006 Form 10-K, 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 benefit
plans in the December 31, 2006 balance sheet, with a corresponding adjustment to other comprehensive loss, net
of tax of $63.9 million. The adoption did not have an impact on the Company’s debt covenants. At December 31,
2007 and 2006, the Company continued to use the earlier measurement date of September 30, and is currently
reviewing the transition alternatives available and the related impact.

In June 2006, the FASB issued FASB Interpretation No. 48, “Accounting for Uncertainty in Income
Taxes—an interpretation of FASB Statement No. 109” (“FIN 48”), which was effective for fiscal years
beginning after December 15, 2006. FIN 48 clarified 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 provided guidance on derecognition, measurement, classification, interest and penalties,
accounting in interim periods, disclosure and transition. The Company adopted the provisions of FIN 48, on
January 1, 2007. As a result of the implementation of FIN 48, the Company recognized no increase in the
liability for unrecognized tax benefits. See Note 8 for additional required disclosures.

In February 2006, the FASB issued SFAS 155, “Accounting for Certain Hybrid Financial Instruments—an
amendment of FASB Statements No. 133 and 140” (“SFAS 155”), which was effective for all financial
instruments acquired or issued after the beginning of an entity’s fiscal year 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. The Company adopted this guidance effective
January 1, 2007 and there was no impact on the Company’s financial statements.

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 was 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

74

change the existing base contract and do not require further evaluation under SOP 05-1. The Company adopted
this guidance effective January 1, 2007 and there was no impact on the Company’s financial statements.

Pending Adoption of Accounting Pronouncements

In September 2006, the FASB issued SFAS 157, “Fair Value Measurements” (“SFAS 157”), which is
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 new requirements for
additional fair-value measures in financial statements. The Company adopted this guidance effective January 1,
2008.

In February 2007, the FASB issued SFAS No. 159, “The Fair Value Option for Financial Assets and
Financial Liabilities” (“SFAS 159”). SFAS 159 expands the standards under SFAS 157 to provide entities with a
one-time election to measure existing financial instruments and certain other items at fair value at the date of
adoption. SFAS 159 also amends SFAS No. 115 “Accounting for Certain Investments in Debt and Equity
Securities” to require a specific presentation of investments categorized as available-for-sale. This statement is
effective for the first fiscal year that begins after November 15, 2007. The Company adopted this guidance on
January 1, 2008 and did not elect the fair value option for any of its eligible assets or liabilities as of this date.

In June 2007, the FASB issued EITF 06-11, “Accounting for Income Tax Benefits of Dividends on Share-
Based Payment Awards” (“EITF 06-11”). EITF 06-11 addresses how a company should recognize the income tax
benefit received on dividends that are (a) paid to employees holding equity-classified non-vested shares, equity-
classified non-vested share units, or equity-classified outstanding share options, and (b) charged to retained
earnings under FAS 123(R). The tax benefit received on dividends paid to employees associated with their share-
based awards should be recorded in additional paid-in capital until the award is settled through exercise (if the
award is an option) or vesting (if the award is non-vested stock). This will be effective for tax benefits of
dividends declared in fiscal years beginning after December 15, 2007. The Company adopted this guidance
effective January 1, 2008 and it had no material impact on the Company’s financial statements.

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.

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 40% 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

75

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

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, 2007 and 2006, and the related consolidated statements of income, stockholders’
equity, and cash flows for each of the three years in the period ended December 31, 2007. 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, 2007 and
2006, and the consolidated results of their operations and their cash flows for each of the three years in the period
ended December 31, 2007, 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 1 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), State Auto Financial Corporation’s internal control over financial reporting as of December 31,
2007, based on criteria established in Internal Control—Integrated Framework issued by the Committee of
Sponsoring Organizations of the Treadway Commission and our report dated March 7, 2008 expressed an
unqualified opinion thereon.

Report of Independent Registered Public Accounting Firm

The Board of Directors and Stockholders of
State Auto Financial Corporation

We have audited State Auto Financial Corporation’s internal control over financial reporting as of
December 31, 2007, based on criteria established in Internal Control—Integrated Framework issued by the
Committee of Sponsoring Organizations of the Treadway Commission (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 included in the accompanying
Management’s Annual Report on Internal Control Over Financial Reporting. Our responsibility is to express an
opinion on 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, assessing the risk that a
material weakness exists, testing and evaluating the design and operating effectiveness of internal control based
on the assessed risk, 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, State Auto Financial Corporation maintained, in all material respects, effective internal

control over financial reporting as of December 31, 2007, 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, 2007
and 2006, and the related consolidated statements of income, stockholders’ equity, and cash flows for each of the
three years in the period ended December 31, 2007 of State Auto Financial Corporation and our report dated
March 7, 2008 expressed an unqualified opinion thereon.

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

Notes to Consolidated Financial Statements

1. Summary of Significant Accounting Policies

a. Principles of Consolidation

The consolidated financial statements include State Auto Financial Corporation (“State Auto Financial”)

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

Strategic Insurance Software, Inc. (“S.I.S.”), 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.

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

83

STATE AUTO FINANCIAL CORPORATION AND SUBSIDIARIES

Notes to Consolidated Financial Statements, Continued

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
formulate estimates of the ultimate cost
to
uncertainties for various reasons. The Company’s results of operations and financial condition could be
materially impacted in future periods should the ultimate payments required to settle claims vary from the
amount of the liability currently provided.

to settle claims. These estimates by their nature are subject

Certain reclassifications have been made to the 2006 and 2005 financial statements to conform to the 2007
presentation. This includes reclassifications in the consolidated balance sheet that consist of separately presenting
certain other invested assets that are included in the Company’s available-for-sale portfolio from all other
invested assets as well as aggregating the Company’s benefit plans where permitted, namely postretirement and
pension liability or asset presentation. Consistent with balance sheet reclassifications, 2006 and 2005 line items
in the consolidated statement of cash flows have been combined to conform with balance sheet presentation,
specifically postretirement and pension benefits (assets).

d. Investments

Investments in fixed maturities, equity securities and certain other invested assets 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. For declines in value that are not

84

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

Notes to Consolidated Financial Statements, Continued

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. When a decline
in fair 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, 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.

Interest and penalties related to unrecognized tax obligations are recorded in the balance sheet as other

liabilities, and recognized in the income statement as other expenses.

85

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

Notes to Consolidated Financial Statements, Continued

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 $29.3 million and $29.0
million at December 31, 2007 and 2006, respectively, has been established to cover the estimated ultimate cost to
settle 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. Comprehensive Income (Loss)

Comprehensive income (loss) 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 (loss) includes
net income and other comprehensive income (loss). Other comprehensive income (loss) includes all other
non-owner related changes to equity and includes net unrealized gains and losses on available-for-sale
investments, derivative instruments and unrecognized benefit plan obligations, adjusted for deferred federal
income taxes.

k. Share-Based Compensation

See Note 12—Share-Based Compensation regarding the Company’s adoption of SFAS 123(R) “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 and amortized over their vesting period. The fair value of each stock option 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 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.

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

Notes to Consolidated Financial Statements, Continued

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 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,

issued SFAS No. 158,
the Financial Accounting Standards Board (“FASB”)
“Employers’ Accounting for Defined Benefit Pension and Other Postretirement Plans, an amendment of FASB
Statements No. 87, 88, 106, and 132(R)” (“SFAS 158”) that requires employers with 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 ending
after December 15, 2008. On December 31, 2006, the Company adopted the recognition and disclosure
provisions of SFAS 158, which had no effect on the Company’s consolidated statement of income for year ended
December 31, 2006, or for any prior period presented in the 2006 Form 10-K, and it will not affect the
Company’s operating results in future periods. Adopting SFAS 158 required the Company to recognize the

87

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

Notes to Consolidated Financial Statements, Continued

funded status (i.e. the difference between the fair value of plan assets and the benefit obligations) of its benefit
plans in the December 31, 2006 balance sheet, with a corresponding adjustment to other comprehensive loss, net
of tax of $63.9 million. The adoption did not have an impact on the Company’s debt covenants. At December 31,
2007 and 2006, the Company continued to use the earlier measurement date of September 30, and is currently
reviewing the transition alternatives available and the related impact.

In June 2006, the FASB issued FASB Interpretation No. 48, “Accounting for Uncertainty in Income
Taxes—an interpretation of FASB Statement No. 109” (“FIN 48”), which was effective for fiscal years
beginning after December 15, 2006. FIN 48 clarified 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 adopted the provisions of FIN 48, on
January 1, 2007. As a result of the implementation of FIN 48, the Company recognized no increase in the
liability for unrecognized tax benefits. See Note 8 for additional required disclosures.

In February 2006, the FASB issued SFAS 155, “Accounting for Certain Hybrid Financial Instruments—an
amendment of FASB Statements No. 133 and 140” (“SFAS 155”), which was effective for all financial
instruments acquired or issued after the beginning of an entity’s fiscal year 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. The Company adopted this guidance effective
January 1, 2007 and there was no impact on the Company’s financial statements.

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 was 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. The Company adopted
this guidance effective January 1, 2007 and there was no impact on the Company’s financial statements.

Pending Adoption of Accounting Pronouncements

In September 2006, the FASB issued SFAS 157, “Fair Value Measurements” (“SFAS 157”), which is 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 new requirements for additional
fair-value measures in financial statements. The Company adopted this guidance effective January 1, 2008.

88

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

Notes to Consolidated Financial Statements, Continued

In February 2007, the FASB issued SFAS No. 159, “The Fair Value Option for Financial Assets and
Financial Liabilities” (“SFAS 159”). SFAS 159 expands the standards under SFAS 157 to provide entities with a
one-time election to measure existing financial instruments and certain other items at fair value at the date of
adoption. SFAS 159 also amends SFAS No. 115 “Accounting for Certain Investments in Debt and Equity
Securities” to require a specific presentation of investments categorized as available-for-sale. This statement is
effective for the first fiscal year that begins after November 15, 2007. The Company adopted this guidance on
January 1, 2008 and did not elect the fair value option for any of its eligible assets or liabilities as of this date.

In June 2007, the FASB issued EITF 06-11, “Accounting for Income Tax Benefits of Dividends on Share-
Based Payment Awards” (“EITF 06-11”). EITF 06-11 addresses how a company should recognize the income tax
benefit received on dividends that are (a) paid to employees holding equity-classified non-vested shares, equity-
classified non-vested share units, or equity-classified outstanding share options, and (b) charged to retained
earnings under FAS 123(R). The tax benefit received on dividends paid to employees associated with their share-
based awards should be recorded in additional paid-in capital until the award is settled through exercise (if the
award is an option) or vesting (if the award is non-vested stock). This will be effective for tax benefits of
dividends declared in fiscal years beginning after December 15, 2007. The Company adopted this guidance
effective January 1, 2008 and it had no material impact on the Company’s financial statements.

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

Note 3 for additional fair value disclosures.

The Company recognized realized losses on other-than-temporary impairments of $0, $3.8 million and $0.6
million on its fixed maturity portfolio in 2007, 2006 and 2005, respectively. The Company recognized realized
losses on other-than-temporary impairments of $1.9 million, $1.6 million and $1.0 million in 2007, 2006 and
2005, respectively on its equity security portfolio. During 2007 the Company outsourced a segment of its
investment portfolio to external money managers. When assessing other-than-temporary impairment on this
segment of the investment portfolio, management considers its inability to make the assertion regarding its intent
to hold a particular security that is currently valued below cost until recovery in the near term. The Company
reviewed its investments at December 31, 2007, and determined no additional other-than-temporary impairment
exists in the gross unrealized holding losses due to the evidence that would indicate only temporary impairment.

Proceeds on sales of available-for-sale securities in 2007, 2006, and 2005 were $262.2 million, $275.2

million and $340.1 million, respectively.

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 for these instruments approximate their fair
value.

93

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

Notes to Consolidated Financial Statements, Continued

Notes payable: The carrying amount of the Trust Preferred note (defined in Note 6b) in the consolidated
balance sheets approximates its fair value as the interest rate adjusts quarterly. The $100.0 million, 6.25%
Senior Notes (defined in Note 7) have a fair value of $103.6 million and $99.1 million at December 31,
2007 and 2006, respectively. The fair value of the Senior Notes is based on the quoted market price at
December 31, 2007 and 2006, respectively.

The Company recorded favorable loss and loss expense reserve development in 2007, 2006, and 2005 of
$54.7 million, $71.7 million and $44.3 million, respectively. The favorable development in 2007 was primarily
due to auto liability and other liability losses being approximately $23.5 million less than anticipated as current
loss projections using more mature claim data resulted in lower claim severity than in past projections, loss
adjustment expenses being approximately $11.8 million lower than anticipated in proportion to losses and ceded

STATE AUTO FINANCIAL CORPORATION AND SUBSIDIARIES

losses being above previously anticipated levels by approximately $10.0 million. The favorable development in
2006 was largely due to ceded reserves being above previously anticipated levels by $23.7 million, auto liability
losses being $24.7 million less than anticipated as current loss projections using more mature claim data resulted
in lower average claim severities than in past projections, and loss adjustment 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.

5. Reinsurance

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

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

Prior to the reinsurance transaction with 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
Security Insurance Company (“Meridian Security”) and Meridian Citizens Mutual
Insurance Company
(“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.

In general, 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.

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

Notes to Consolidated Financial Statements, Continued

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

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

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 and Beacon National Insurance
Company (“Beacon National”), a subsidiary of State Auto Mutual, in the amount of $100.0 million excess of
$135.0 million 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 $3.1 million, $3.0 million
and $2.7 million for 2007, 2006 and 2005, 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.

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

Notes to Consolidated Financial Statements, Continued

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.

The following provides a summary of the ceded reinsurance transactions on the Company’s balance sheet

and income statement for the reinsurance agreement between SA National and State Auto Mutual:

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, 2007 and 2006 is approximately $266.9 million and $250.3 million, respectively.

b. Notes Payable

In May 2003, State Auto Financial formed a Delaware business trust (the “Capital Trust) that issued $15.0
million mandatorily redeemable preferred capital securities to a third party and $0.5 million of its common
securities representing all outstanding common securities to State Auto Financial (collectively, the capital and
common securities are referred to as the “Trust Securities”). The Capital Trust loaned $15.5 million in proceeds
from the issuance of its Trust Securities to State Auto Financial in the form of a Floating Rate Junior
Subordinated Debt Securities due in 2033 (the “Subordinated Debentures”). The Subordinated Debentures are the
Capital Trust’s only assets along with any interest accrued thereon. Interest on the Trust Securities are payable

98

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

Notes to Consolidated Financial Statements, Continued

quarterly at a rate equal
to the three-month LIBOR rate plus 4.20% adjusted quarterly (total 9.32% at
December 31, 2007). 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, thereby payments from the Subordinated Debentures finance the distributions paid
on the Trust Securities. State Auto Financial has the right to redeem the Subordinated Debentures, in whole or in
part, on or after May 23, 2008. In accordance with FASB Interpretation No. 46(R), (and related amendments and
interpretations) “Consolidation of Variable Interest Entities,” State Auto Financial determined that the business
trust is a variable interest entity for which it is not the primary beneficiary and therefore, does not consolidate the
Capital Trust with the Company. State Auto Financial has unconditionally and irrevocably guaranteed payment
of any required distributions on the capital securities, the redemption price when the capital securities are
redeemed, and any amounts due if the Capital Trust is liquidated or terminated. State Auto Financial’s equity
interest in the Capital Trust is included in other invested assets.

In December 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% for 2005.

c. Management Services

Stateco provides State Auto Mutual and its affiliates investment management services. Investment
management income is recognized quarterly based on a percentage of the average fair value of investable assets
and the equity portfolio performance of each company managed. Revenue related to these services amounted to
$2.8 million, $2.5 million and $2.3 million in 2007, 2006 and 2005, respectively, and is included in other income
(affiliates).

7. Notes Payable and Credit Facility

In 2003, State Auto Financial 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 State Auto Financial’s subsidiaries and thereby are effectively subordinated to all subsidiaries’ existing
and future indebtedness. As of December 31, 2007, State Auto Financial was in compliance with all covenants
related to 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 each for 2007,
2006 and 2005) as the underlying interest expense is recognized on the Senior Notes.

On July 12, 2007, State Auto Financial terminated its previous credit agreement which provided for a
$100.0 million five-year unsecured revolving credit facility and entered into a new credit agreement (“Credit
Agreement”) with a syndicate of lenders which provides for a $200.0 million five-year unsecured revolving
credit facility (“Credit Facility”). State Auto did not borrow any funds under the previous credit agreement.
During the term of the Credit Facility, the Company has the right to increase the total facility to a maximum total
facility amount of $250.0 million, provided that no event of default has occurred and is continuing. While the
Credit Facility will be available for general corporate purposes, including working capital, acquisitions and
liquidity purposes, the Company presently intends to keep $100.0 million of the Credit Facility available in the
event there is a need to fund losses under the catastrophe reinsurance program with State Auto P&C. The Credit
Facility provides for interest-only payments during its term, with principal due in full at maturity. Interest is

Notes to Consolidated Financial Statements, Continued

based on either a London interbank market rate or a base rate plus a calculated margin amount. The Credit
Agreement contains certain covenants, including financial covenants that require the Company to maintain a
minimum net worth and not exceed a certain debt to capitalization ratio. As of December 31, 2007, State Auto
Financial had not made any borrowings and was in compliance with all of the covenants under the Credit
Agreement. State Auto Financial incurred $0.5 million in issuance costs related to the Credit Agreement, which
is recorded in other assets and is being amortized into expense ($0.1 million for 2007) over the life of the Credit
Agreement.

8. Federal Income Taxes

At December 31, 2007, the Company carried no balance for uncertain tax positions.

The Company had no accrual for the payment of interest and penalties at December 31, 2007 or 2006.

The Company is currently not under audit by either the Internal Revenue Service or any state jurisdiction for
income tax purposes and all prior audits have been settled. Tax years 2004 through 2006 remain open for audit
for federal income tax purposes.

The reconciliation between actual federal income tax expense (benefit) and the amount computed at the

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, 2007 or 2006.

9. Pension and Postretirement Benefit Plans

All Company personnel are employees of State Auto P&C. The Company, through State Auto P&C,
provides management and operation services under management agreements for all insurance and non-insurance
affiliates. The annual periodic costs related to the Company’s benefit plans are allocated to affiliated companies
based on allocations pursuant to intercompany management agreements.

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

In addition to the defined benefit pension 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
benefit pension 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 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

101

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

Notes to Consolidated Financial Statements, Continued

SFAS 87 and SFAS 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 SFAS 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.

The Company’s 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 the mix of the 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 benefit plan’s investment policy objective is to preserve the investment principal while generating
income and appreciation in fair value to meet the benefit plans’ obligations. The benefit 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 benefit plans’ liabilities and cash requirements are
predictable, the liquidity requirements are somewhat moderate. During 2007, the following asset allocation
targets, as a percentage of total fair value, were approved. Management is in the process of moving towards these
allocation targets as funds become available.

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 2008 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 $2.6 million, $2.5 million and $2.4 million for the
years 2007, 2006 and 2005, respectively.

10. Stockholders’ Equity

a. Treasury Shares

On August 17, 2007, State Auto Financial’s board of directors authorized a plan to repurchase, from time to
time, up to 4.0 million of its common shares, or approximately 10% of State Auto Financial’s outstanding shares,
over a period extending to and through December 31, 2009 (the “Repurchase Plan”). Under the Repurchase Plan,
State Auto Financial may repurchase shares from State Auto Mutual in amounts that are proportional to the
respective current ownership percentages of State Auto Mutual, which is approximately 64%, and other
shareholders. State Auto Financial’s total share repurchase activity in 2007 was approximately 0.8 million
common shares at an average repurchase price of $27.21 per share for a total of $22.1 million.

b. Dividend Restrictions and Statutory Financial Information

State Auto P&C, Milbank, Farmers, SA Ohio and SA National are subject to regulations and restrictions
under which payment of dividends from statutory earned surplus can be made to State Auto Financial during the
year without prior approval of regulatory authorities. Pursuant to these rules, at December 31, 2007, adjusted for
dividend payments made in the previous twelve-month period, approximately $79.6 million is available for
payment to State Auto Financial from its insurance subsidiaries in 2008 without prior approval. In 2007 State
Auto Financial received dividends of $50.0 million from its insurance subsidiaries, $0 in 2006, and $40.5 million
in 2005.

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
the Company recognized share-based compensation within its financial
independent
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,

108

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. As of December 31, 2007, a total of 1.1 million 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 2007,
2006 and 2005 were 0.4 million, 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 Restriction Period. Restricted shares granted for 2007 and 2006
were 32,000 and 10,500, respectively, with a weighted average grant date fair value of $29.98 and $31.94,
respectively. There were no restricted shares granted prior to January 1, 2006.

As of December 31, 2007, there was $1.0 million of total unrecognized compensation cost related to
non-vested restricted share compensation arrangements. The remaining cost is expected to be recognized over a
period of 2.75 years. No shares vested during the years ended December 31, 2007 and 2006.

Employee Stock Purchase Plan

The Company also has a broad-based employee stock purchase plan, under which employees of the
Company may choose at two different specified time intervals each year to have up to 6% of their annual base
earnings withheld to purchase the Company’s common shares. The purchase price of the common shares is 85%

109

STATE AUTO FINANCIAL CORPORATION AND SUBSIDIARIES

of the lower of its beginning-of-interval or end-of-interval market price. The Company has reserved 3.4 million
common shares under this plan. As of December 31, 2007, a total of 2.4 million common shares have been
purchased under this plan. This plan remains in effect until terminated by the board of directors.

Outside Directors 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 11,200 and
9,800 RSUs granted in 2007 and 2006, respectively. There were no RSUs granted by the Company prior to
January 1, 2006.

During 2007 and 2006, common shares valued at approximately $9,000 and $60,000, respectively, were

distributed by the Company under the Outside Directors RSU Plan. No distributions were made in 2005.

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.

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 December 31, 2007, 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

110

Notes to Consolidated Financial Statements, Continued

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 2007, 2006 and 2005 were 15,862, 16,452 and 29,505,
respectively. The Agent Stock Option Plan terminates May 27, 2008.

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 2007, 2006,
and 2005. 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 independent 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:

15. Reportable Segments

Due to internal reorganization efforts which occurred throughout most of 2006, that included realigning
the Company changed its significant reportable
people, processes, systems and compensation programs,
segments from standard insurance and nonstandard insurance to the new segments described below, effective
January 1, 2007. Prior reporting periods have been restated to conform to the new segment presentation

The Company has three significant reportable segments: personal

insurance, business insurance, and
investment operations. The reportable insurance segments are business units managed separately because of the
differences in the type of customers they serve or products they provide or services they offer. The insurance
segments operate primarily in the central and eastern United States, excluding New York, New Jersey, and New
England states, distributing products through the independent insurance agency system. The personal insurance
segment provides primarily personal auto (standard and nonstandard) and homeowners to the personal insurance
market. The business insurance segment provides primarily commercial auto, commercial multi-peril, fire and
allied lines, other and product liability and workers’ compensation insurance to small to medium sized businesses
within the commercial insurance market. The investment operations segment, managed by Stateco, provides
investment services for the Company’s invested assets.

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

Notes to Consolidated Financial Statements, Continued

The Company evaluates the performance of its insurance segments using industry financial measurements
determined based on Statutory Accounting Principles (“SAP”), which include loss and loss adjustment expense
ratios, underwriting expense ratios, combined ratios, statutory underwriting gain (loss), net premiums earned and
net written premiums. One of the most significant differences between SAP and GAAP is that SAP requires all
underwriting expenses to be expensed immediately and not deferred and amortized over the same period the
premium is earned as under GAAP.

Asset information by segment is not reported for the insurance segments because the Company does not
produce such information internally. The investment operations segment is evaluated based on investment returns
of assets managed by Stateco.

17. Contingencies

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, 2007. 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.

18. Subsequent Event (unaudited)

Effective January 1, 2008, the Pooling Arrangement, described in Note 6a, was further amended to add
Patrons Mutual Insurance Company of Connecticut (“Patrons Mutual”), Litchfield Mutual Fire Insurance
Company (“Litchfield”) and Beacon National as participants and the middle market business of State Auto
Mutual and Meridian Security to the pool. Patrons Mutual and Litchfield are affiliate companies of State Auto
Mutual. Concurrently with the addition of the three companies, certain individual participant percentages of State
Auto Mutual and its subsidiaries and affiliates were adjusted but continue to maintain an overall 20%
participation percentage; STFC’s insurance subsidiaries will maintain its 80% participation percentage.

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, 2007, 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.

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 have been no changes 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.
