Dear 
Shareholders,

Robert P. Restrepo Jr.

$0.50

DIVIDENDS PAID
(per share)

$0.75

State Auto is well-positioned to grow profits and premiums 
exceeding both the industry and our peer companies. We’ve taken
steps to substantially improve the profitability of our homeowners
book. Our expansion in geography and products is delivering new
opportunities. The strong relationships we share with our inde-
pendent agents remain the bedrock of our business.  

In 2010, State Auto reported improved profitability with a com-
bined ratio of 104.6 and earnings per share of $0.62. We improved
underwriting results despite a difficult operating environment and
uncertain economy. Personal insurance led the way through pric-
ing, underwriting, and claim initiatives and normalized catastro-
phe and weather losses. We faced challenges in business
insurance, primarily due to large losses in our normally strong
commercial auto and general liability lines.

We have taken dramatic and effective steps to deliver on the
four pillars of our business strategy: Rational Growth, Underwrit-
ing Profit, Risk Management and Capital Management. We are
also taking additional steps to improve underwriting results and
return on equity, which will drive appreciation of our stock price.
We have excellent prospects for 2011 and beyond. 

• We remain a premier, profitable and growing personal  

automobile company.
State Auto’s growth and profit margins have traditionally  
exceeded the industry’s and that of our peer group. This 
performance continued in 2010 with a premium increase of 
4.2%,  price increase of 3.2%, and introduction of a host of  
new claim initiatives which improved our loss ratio by 1.5 
points. We will leverage our strong market position as we 
grow in new states and with new agents. State Auto is a top 
quartile company in personal auto profit and growth. We  
expect it to remain the engine for profitable growth.

• Our homeowner results are expected to continue to improve. 

Since homeowners represents 20% of our business,  
strengthening this line will have a meaningful impact on 
earnings per share. Our catastrophe and non-catastrophe loss 
results were lower in 2010, thanks to several tough but  
responsible decisions. Homeowners saw a 10.7% price 
increase. Our aggressive insurance-to-value program is 
expected to contribute a 2.8% increase in written premium 
in 2011, while protecting policyholders by maintaining 
appropriate insured values.

STFC has paid a dividend
in 78 straight quarters: 
every quarter since its
inception. The dividend
has never been lowered.

State Auto’s overall
premium growth of 9.5%
should exceed industry
results for 2010. Sales in
the personal insurance
lines were strong, 
growing 6.1%, related 
to price increases and
continued growth 
from our expansion
states of Arizona, 
Colorado,Connecticut 
and Texas.

Business insurance sales
overall were up 15.5%,
with business written
through RED accounting
for 19.1 points, while
historic mainline business
was down 3.6 points.

The first phase of our by-peril homeowner rating plan is 
now effective in 11 states that accounted for over 75% of 
the previous five years’ wind and hail losses.  Claim catas- 
trophe teams, large loss teams, and new field adjusters will 
better manage our loss adjustment expenses and indemnity 
payout. We expect to hit our loss ratio targets in the near 
future, regardless of the pricing environment.

• We will benefit from a personal lines market that is increas-

ingly attractive to independent agents. 
State Auto’s strength in the automobile and homeowners 
lines makes us an attractive choice for our agency force. As 
agents compare positive trends in personal lines to thin pric- 
ing in commercial lines, more are investing in this segment. 
We are heavily cross sold in personal lines and have strong 
retention with independent agents who represent us. Our 
total account approach and excellent retention will be lever- 
aged as we move into new demographic and geographic 
market segments. 

• We have opportunities in standard and specialty commercial 
lines to drive growth, technology, productivity and effective  
cost structure.
Many of our agents are active in the commercial lines mar- 
ket. Our investments in new products such as BOP Choice 
and new technology such as bizXpressSM are beginning to 
spur production. Our loss ratios remain good, but productiv- 
ity levels are lower than average contributing to higher than  
desirable expense ratios. Over the next two years, we will 
introduce new technology and business processes that target 
a 3-5 point reduction in commercial lines expense ratios. 

•  Integration of our specialty insurance businesses will  

enhance the management and marketing of this increasingly 
important segment.
As of January 1, 2011, the results of our three specialty busi- 
ness units, Rockhill Insurance, Workers Compensation and 
Risk Evaluation and Design, LLC (RED), will be reported as 
part of a new specialty insurance segment and, over time, 
should become an important part of our profit story.

• Agency relations are remarkably good. 

Independent agents are increasingly reaching out and doing 
more business with companies they trust. State Auto is one 
of those companies and we will do what is necessary to keep 
their trust and increase our share of their business. We re-
ceive high marks for the quality of our people, service and 
marketing support following the restructuring of our field 
sales, underwriting and claim organizations. This restructur- 
ing is complete and positions us for higher levels of produc- 
tivity and service and lower levels of expense. In 2010, we 
reduced our expense ratio from 34.1% to 33.8% while most 
of our competitors experienced increases. In addition, our  
loss adjustment expense ratio (which is imbedded in our loss 
ratio) declined from 12.1% to 10.5%. We’re positioned for 
further improvements this year. 

People are the most critical factor to State Auto’s success

Agents, policyholders and claimants like and trust State Auto.
It’s a trait that we must preserve and grow. We do that by attract-
ing and retaining the highest quality people, including individuals
in leadership roles.

In 2010, we began a process with the Board of Directors to 
refresh our business strategy, including the make-up and assign-
ments of our leadership team. In early 2011, we introduced a new
senior management structure that provides alignment and 
accountability required to successfully and flawlessly implement
our strategy.

Among these changes is the departure of Chief Operating Offi-

cer Mark Blackburn, who will retire later this year. Mark joined
State Auto in 1999 to lead our reinsurance operation after holding
executive-level positions with Grange Mutual Casualty Group and
General Reinsurance Corporation. I want to thank him for his
contributions and commitment to State Auto, and wish him the
best in the future.

We restructured the executive leadership team to broaden its 

responsibilities (see sidebar).  I’m energized by our team and 
excited about a future in which we solidify our position as a 
special and differentiated regional company.

State Auto’s story is worth telling; one that will get better as our
profit improvement momentum builds. We expect that the people
and actions we have in place will sustain that momentum and 
produce the kind of underwriting combined ratio results and dou-
ble digit returns on equity that will contribute to more attractive
investment returns in the future.  

I look ahead to 2011 with great enthusiasm and confidence, 

and thank you for your continued support of State Auto 
Financial Corporation.

Loss adjustment expenses or LAE . . . . . The expenses of settling claims, including legal and other fees, and
the portion of general expenses allocated to claim settlement. LAE is
comprised of allocated loss adjustment expenses or “ALAE” and
unallocated loss adjustment expenses or “ULAE.” 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 while, ULAE are those costs incurred in settling claims, such
as in-house processing costs, which cannot be associated with a
specific claim.

Loss and LAE ratio or loss ratio . . . . . . . For both SAP and GAAP, it is the ratio of incurred losses and LAE to

earned premiums.

Loss reserves . . . . . . . . . . . . . . . . . . . . . . Liabilities established by insurers and reinsurers to reflect

the
estimated cost of claims incurred that the insurer or reinsurer will
ultimately be required to pay in respect of insurance or reinsurance it
has written. Reserves are established for losses and for LAE, and
consist of case reserves and IBNR reserves.

Managing general underwriter or

MGU . . . . . . . . . . . . . . . . . . . . . . . . . . An independent

insurance professional

firm that acts as an
intermediary between the insurer and retail agents, much like a
wholesaler. MGUs frequently have binding authority to issue
insurance policies on behalf of an insurer that fit into the underwriting
guidelines provided by that insurer. MGUs typically are compensated
by an override commission on the insurance coverages sold by their
sub-agents.

National Association of Insurance

Commissioners or NAIC . . . . . . . . . . . An organization of the insurance commissioners or directors of all 50
states, the District of Columbia and the five U.S. territories organized
to promote consistency of
regulatory practices and statutory
accounting standards throughout the United States.

Net premiums written to surplus ratio or

leverage ratio . . . . . . . . . . . . . . . . . . . . A SAP calculation which measures statutory surplus available to
absorb losses. This ratio is calculated by dividing the net statutory
premiums written for a rolling twelve month period by the ending
statutory surplus for the period. For example, a ratio of 1.5 means that
for every dollar of surplus, the insurer wrote $1.50 in premiums.

Net written premiums . . . . . . . . . . . . . . . Direct written premiums plus assumed reinsurance premiums less
ceded reinsurance premiums.

Non-admitted insurer or surplus lines

carrier

. . . . . . . . . . . . . . . . . . . . . . . . . An insurer that is not required to be licensed in a state but is allowed
to do business in that state subject to certain regulatory oversight by
that state’s insurance regulatory authority. Non-admitted insurers are
not subject to most of the rate and form regulations imposed on
admitted insurers because they write specialized property and liability
coverages, also known as excess and surplus lines insurance, which
allows them the flexibility to change coverages offered and rates
charged without time constraints and financial costs associated with
the filing process. As such, these insurers offer an opportunity for
coverage for specialized exposures that otherwise might not be
insurable.

Retail agent or retail agency . . . . . . . . . . An independent insurance professional who represents, and acts as an
intermediary for,
admitted insurers, generally recommending,
marketing and selling insurance products and services to insurance
consumers.

Return on average equity . . . . . . . . . . . . . The percent derived by dividing net

income by average total

stockholders’ equity.

Risk-based capital or RBC . . . . . . . . . . . A measure adopted by the NAIC and state regulatory authorities for
determining the minimum statutory capital and surplus requirements
of insurers. Insurers having total adjusted capital
less than that
required by the RBC calculation will be subject to varying degrees of
regulatory action depending on the level of capital inadequacy.

Risk retention groups . . . . . . . . . . . . . . . An insurance arrangement where members of a similar profession or

Standard insurance . . . . . . . . . . . . . . . . .

business band together to self-insure their exposure.

Insurance which is typically written by admitted insurers. Our
personal and business insurance segments are comprised of standard
insurance.

Statutory accounting practices or SAP . . The practices and procedures prescribed or permitted by state
insurance regulatory authorities in the United States for recording
transactions and preparing financial statements.

Statutory surplus . . . . . . . . . . . . . . . . . . . Under SAP, the amount remaining after all liabilities, including loss
reserves, are subtracted from all admitted assets. Admitted assets are
assets of an insurer prescribed or permitted by a state to be recognized
on the balance sheet prepared in accordance with SAP.

Underwriting gain or loss . . . . . . . . . . . . Under SAP, earned premiums less loss and LAE and underwriting

expenses.

Unearned premiums . . . . . . . . . . . . . . . . The portion of written premiums that applies to the unexpired portion
of the policy term. Unearned premiums are not recognized as
revenues under both SAP and GAAP.

Wholesale broker . . . . . . . . . . . . . . . . . . . An independent

insurance professional who offers

specialized
insurance products and serves as an intermediary between a retail
agent and an insurer, while typically having no contact with the
insured. A wholesale broker may represent both admitted and non-
admitted insurers, and may offer both standard and excess and surplus
lines insurance.

Item 1. Business

PART I

State Auto Financial is an Ohio domiciled 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’s
subsidiaries include State Auto P&C, Milbank, Farmers, and SA Ohio, each of which is a property and casualty
insurance company, and Stateco, which provides investment management services to affiliated insurance
companies. State Auto Financial’s nonstandard automobile insurance subsidiary, SA National, was sold to
Hallmark Insurance Company on December 31, 2010. In deciding to sell SA National, we considered those
businesses core to our long-term strategy and concluded that the nonstandard auto market was no longer a
strategic fit for us.

Our parent company is State Auto Mutual, an Ohio domiciled mutual property and casualty insurance
company organized in 1921. It owns approximately 63% of State Auto Financial’s outstanding common shares.
State Auto Mutual’s other subsidiaries and affiliates include SA Florida, SA Wisconsin, Meridian Security,
Meridian Citizens Mutual, Beacon National, Patrons Mutual, Litchfield and the Rockhill Insurers, each of which
is a property and casualty insurance company. In 2007, State Auto Mutual acquired the Beacon Insurance Group
and affiliated with the Patrons Insurance Group. In 2009, State Auto Mutual acquired the Rockhill Insurance
Group.

The operations of the State Auto Group are headquartered in Columbus, Ohio.

MANAGEMENT AGREEMENT

Through various management and cost sharing agreements, State Auto P&C provides the employees to
perform all organizational, operational and management functions for the State Auto Group while State Auto
Mutual provides certain operating facilities, including our corporate headquarters.

Our primary management agreement, which we refer to as the 2005 Management Agreement, has a ten year
term and renews for an additional ten-year period unless terminated sooner in accordance with its terms. If the
2005 Management Agreement was 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 “Properties” included in Item 2 of this Form 10-K.

FINANCIAL INFORMATION ABOUT SEGMENTS

During 2010, we operated our business in three reportable segments: personal insurance, business insurance
(the “insurance segments”), and investment operations. The three segments reflected the manner in which we
managed our business and reported our results internally to our principal operating decision makers. In 2010, the
State Auto Group began writing new commercial specialty business through RED, which allowed us to offer
insurance coverages in the program and alternative risk markets for business products such as general liability,
commercial auto, workers’ compensation and property. In 2010, the financial results of business written through
RED were included in our business insurance segment results. See detailed discussion regarding our segments at
Item 7 of this Form 10-K “Management’s Discussion and Analysis of Financial Condition and Results of
Operations—Overview” and Note 16 to our consolidated financial statements included in Item 8 of this
Form 10-K.

With the acquisition of the Rockhill Insurance Group and the build out of RED, in 2010, management
focused on assessing and positioning a realignment of our internal organization, including people, processes and
compensation reward programs, to be more strategic in the personal, business and specialty insurance markets.
Considering these internal changes, and with the inclusion of the Rockhill Insurers into the Pooling Arrangement

3/9/11   9:32 PM

(defined below) as of January 1, 2011, our reportable insurance segments will change from personal and business
insurance to personal insurance, business insurance and specialty insurance, aligning how these insurance
segments report to our principal operating decision makers.

INSURANCE OPERATIONS

The State Auto Group markets a broad line of property and casualty insurance products in all 50 states and
the District of Columbia exclusively through independent insurance agencies, which include retail agents and
wholesale brokers. Prior to the addition of the Rockhill Insurers to the Pooling Arrangement, we marketed our
personal and business insurance segment products in 34 states and the District of Columbia through retail agents.
All of the property and casualty insurance companies in the State Auto Group are admitted insurers, except for
RIC, which is a non-admitted insurer.

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

Competition

The property and casualty insurance industry is highly competitive. We compete with numerous insurance
companies, with varying size and financial resources. We compete in the personal and business insurance
markets based on price; product offerings and innovation; underwriting criteria; quality of service to insureds,
retail agents and wholesale brokers; relationships with our retail agents and wholesale brokers; prompt and fair
claims handling and settlement; financial stability; and technology, making us a preferred business partner. In
addition, because most of our retail agents and wholesale brokers represent more than one insurer, we face
competition within each agency and broker.

Pooling Arrangement

Our Pooled Companies are parties to a quota share reinsurance agreement which we refer to as the “Pooling
Arrangement.” In general, under the Pooling Arrangement, State Auto Mutual assumes premiums, losses and
expenses from each of the remaining Pooled Companies and 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 2011, the Pooling Arrangement covered
all property and casualty insurance written by the Pooled Companies except for business written by the Rockhill
Insurers. As of January 1, 2011, we added the Rockhill Insurers to the pool with a participation percentage of
0.0%. See the detailed discussion of our Pooling Arrangement at Item 7 of this Form 10-K, “Management’s
Discussion and Analysis of Financial Condition and Results of Operations—Pooling Arrangement.”

PERSONAL AND BUSINESS INSURANCE

Products offered in our personal and business insurance segments are marketed exclusively through retail
agents, but the segments are managed separately from each other due to the differences in the types of customer
they serve or products they provide or services they offer.

Products

Personal Insurance

In our personal insurance segment, we write standard insurance covering personal exposures to individuals.

The primary coverages offered are personal auto and homeowners.

Business Insurance

In our business insurance segment, we write standard insurance covering small-to-medium sized
commercial exposures. We offer a broad range of coverages which include commercial auto, commercial multi-
peril, fire & allied and general liability.

Marketing

We market the products of our personal and business insurance segments through approximately 3,400 retail
agencies. We view our retail 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. We continually develop
programs and procedures to enhance our agency relationships, including the following: regular travel by senior
management and regional office staff to meet with agents, in person, in their home states; training opportunities;
and incentives related to profit and growth. In addition, we share the cost of approved advertising with selected
agencies.

We actively help our agencies develop the professional sales skills of 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 regional
office locations from time to time, as well as in our agents’ offices.

We provide our retail 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.

State Auto 10-K High Res for Annual Report.pdf   10

3/9/11   9:32 PM

We have made continuing efforts to use technology to make it easier for our retail agents to do business
with us. We offer internet-based (i) rating, (ii) policy application submission, (iii) execution of changes to
policies for certain products and (iv) claims submission. In addition, we provide our agents with the opportunity
to maintain policyholder records electronically, avoiding the expense of preparing and storing paper records. 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.

Claims

Our internal claims division supports our personal and business insurance through emphasis on 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 $100,000 or above are sent to our home office to be supervised by claims
division specialists. Regions 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.

SPECIALTY INSURANCE

In our specialty insurance segment, we offer commercial coverages that require specialized product
underwriting, claims handling or risk management services through a distribution channel of retail agents and
wholesale brokers, which may include program administrators and other specialty sources. Our specialty
insurance products are written through our admitted and non-admitted insurers. Our specialty insurance segment
is organized into the following three units:

Our RED unit markets and underwrites small-to-medium commercial exposures, offering property and
casualty programs for customers with common risk characteristics or coverage requirements. This unit may also
offer alternative forms of risk protection that include various forms of self-insurance or high deductibles, some of
which may utilize captive insurance arrangements or risk retention groups. Coverages offered by this unit include
commercial auto, workers’ compensation, general liability and property. We use approved external claim
services for claims notification, handling and settlement with centralized management oversight by our home
office team. In 2010, the financial results of our RED unit were included for the first time in our business
insurance segment and accounted for $83.2 million of net written premium. Beginning in 2011, the financial
results of our RED unit will be reported in the specialty insurance segment.

State Auto 10-K High Res for Annual Report.pdf   11

3/9/11   9:32 PM

Our Rockhill unit markets and underwrites commercial exposures which have unique insurance
requirements, including difficult to place classes of commercial business which may require customized rates and
forms, along with customized insurance programs for specialty niche and homogenous groups of exposures.
Coverages offered by this unit may include commercial auto, property, bonds (fidelity and surety) and general
liability. Our Rockhill unit uses a combination of a dedicated internal claims unit and also approved external
claim services for claims notification, handling and settlement with centralized management oversight by our
home office team. In 2010, 2009 and 2008, our business insurance segment included $4.8 million, $3.6 million
and $3.9 million, respectively, of net written premiums from bonds, which will be reported in the specialty
insurance segment beginning in 2011.

Our Workers’ Compensation unit serves the small-to-medium account and association business. This unit
has a dedicated internal claims team emphasizing managed care cost containment strategies including focusing
on the injured employee’s early return to work and cost-effective quality care. In 2010, 2009 and 2008, our
business insurance segment included $38.9 million, $43.3 million and $47.5 million, respectively, of net written
premiums from workers’ compensation business, which will be reported in the specialty insurance segment
beginning in 2011.

REINSURANCE

Members of the State Auto Group follow the customary industry practice of reinsuring a portion of their
exposures and paying to the reinsurers a portion of the premiums received. Insurance is ceded principally to
reduce net liability on individual risks or for individual loss occurrences, including catastrophic losses. Although
reinsurance does not legally discharge the individual members of the State Auto Group from primary liability
under their policies, it does make the assuming reinsurer liable to the extent of the reinsurance ceded. See the
detailed discussion of our reinsurance arrangements at Item 7 of this Form 10-K, “Management’s Discussion and
Analysis of Financial Condition and Results of Operations—Liquidity and Capital Resources—Reinsurance
Arrangements.”

See “Regulation” in this Item 1 for a discussion of the Terrorism Acts.

LOSS RESERVES

We maintain reserves for the eventual payment of losses and LAE for both reported claims and IBNR. Loss
reserves are management’s best estimate at a given point in time of what we expect to pay to settle all losses
incurred as of the end of the accounting period, 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 revise 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 loss reserves currently recorded.

Loss 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
applicable policy provisions. The formula reserves are based on historical paid loss data for similar claims with
provisions for trend changes caused by inflation. Loss reserves for IBNR claims 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 loss 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 loss reserves, see Item 7 of this Form 10-K, “Management’s Discussion and
Analysis of Financial Condition and Results of Operations—Loss and LAE.”

The following table sets forth our development of loss reserves from 2000 through 2010. “Net liability for
losses and loss expenses payable” sets forth the estimated liability for unpaid losses and LAE recorded at the
balance sheet date, net of reinsurance recoverable, for each year shown. This liability represents the estimated
amount of losses and LAE for claims incurred during the current year or incurred during prior years that are
unpaid at the balance sheet date, including IBNR.

The upper section of the table shows the cumulative amounts paid with respect to the previously reported
loss reserve as of the end of each succeeding year. For example, through December 31, 2010, we have paid
121.3% of the losses and LAE that had been incurred but not paid, as estimated at December 31, 2000.

The lower portion of the table shows the current estimate of the previously reported loss 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 year end 2000 loss reserve has developed $94.2 million or 39.8%
deficient through December 31, 2010. This $94.2 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 or deficiency evaluated at
December 31, 2002, on claims incurred in 2000 includes the cumulative redundancy or deficiency for years 2000,
2001 and 2002. 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 2000 and 2001, the Pooling Arrangement was amended to increase our share of premiums, losses and
expenses. An amount of assets equal to the increase in net liabilities was transferred to us from our parent
company in 2000 and 2001 in conjunction with each year’s respective pooling change. In 2005, the MIGI
Insurers were added to the pool and our share of their net liabilities and assets were transferred to us from them.
In 2008, Beacon National, the Patrons Insurance Group, State Auto middle market business and voluntary
assumed reinsurance from parties affiliated with State Auto Mutual were added to the pool, and accordingly net
assets equal to the increase in net liabilities were transferred to us from them. In 2010, SA National and voluntary
assumed reinsurance from third parties unaffiliated with the Pooled Companies that was assumed on or after
January 1, 2009 by State Auto Mutual were added to the pool, and accordingly net assets equal to the increase in
net liabilities were transferred to us from them. The amount of the assets transferred on the reserve liabilities
assumed/ceded in 2000, 2001, 2005, 2008 and 2010 has been netted against and has reduced/increased the
cumulative amounts paid for years prior to 2000, 2001, 2005, 2008 and 2010, respectively.

INVESTMENT OPERATIONS

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

13

State Auto 10-K High Res for Annual Report.pdf   15

3/9/11   9:32 PM

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.

For additional discussion regarding our investments, including the market risks related to our investment
portfolio, see Item 7 of this Form 10-K, “Management’s Discussion and Analysis of Financial Condition and
Results of Operations—Investment Operations Segment.”

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 state 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.

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

14

State Auto 10-K High Res for Annual Report.pdf   16

3/9/11   9:32 PM

surplus as of a certain date, or adjusted net income of the subsidiary for the preceding year. Under current law,
$78.3 million is available in 2011 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 $56.4
million, $11.5 million, and $39.0 million in 2010, 2009, and 2008, 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 2010 which would materially impact
our business.

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. The Fair and Accurate Credit Transactions Act,
passed by the United States Congress in 2003, directed the Federal Trade Commission (“FTC”) to consult with
the Office of Fair Housing and Equal Opportunity on, among other things, how the use of credit information may
affect the availability and affordability of property/casualty insurance, and whether the use of certain factors by
credit scoring systems could have a disparate impact on minorities. In July of 2007, the 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. In 2008, the FTC asked nine of the nation’s largest homeowners insurance companies to
provide information that the FTC says will allow it to determine how consumer credit data is used by the
companies in underwriting and rate setting in this line of business. The FTC continues to analyze the responses
received from the nine insurance companies and expects to issue its report to Congress in late 2011 or 2012,
though no specific release date has been published. Upon release, the results of the study could affect the future
use of credit scoring. 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.

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 NAIC annually tests
insurers’ risk-based capital requirements. As of December 31, 2010, each of the Pooled Companies had adequate
levels of capital as defined by the NAIC with its respective risk-based capital requirements.

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

The Terrorism 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 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 will cover only such acts of terrorism that are not certified acts
under the Terrorism Acts and continue to apply policy exclusions that may limit any coverage from loss due to
nuclear, biological or chemical agents. By enacting the Terrorism Risk Insurance Program Reauthorization Act

15

State Auto 10-K High Res for Annual Report.pdf   17

3/9/11   9:32 PM

of 2007, Congress made modest changes to the previous 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 other important features (such as loss triggers, company deductibles and industry retentions)
were not changed. Our current property reinsurance treaties exclude certified acts of terrorism.

The Federal Insurance Office was established in 2010 by the enactment of the Dodd-Frank Act. The Federal
Insurance Office will be a separate office within the United States Department of Treasury. While lacking
regulatory authority, the primary objectives of the Federal Insurance Office will be to monitor, collect data and
report on the insurance industry. It is not known how this federal office will coordinate and interact with the
NAIC and state insurance regulators.

EMPLOYEES

As of February 25, 2011, we had 2,483 employees. Our employees are not covered by any collective

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

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 loss reserves may be inadequate to

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

We establish loss reserves based on actuarial estimates of the amount to be paid in the future to settle all
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. Loss reserves do not represent an exact calculation of liability, but instead represent
estimates, generally using actuarial projection techniques at a given accounting date. Our loss 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, historical settlement patterns, estimates of trends in claims severity and
frequency, legal theories of liability and other factors. Variables in the loss 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 developments 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 a claim is actually reported to the insurer. We refine loss reserve
estimates in a regular ongoing process as historical loss experience develops and additional claims are reported
and settled. We record adjustments to loss reserves in the results of operations for the periods in which the
estimates are changed. In establishing loss reserves, we take into account estimated recoveries for reinsurance,
salvage and subrogation.

Because estimating loss reserves is an inherently uncertain process, currently established loss reserves may
not be adequate. If we conclude the estimates are incorrect and our loss reserves are inadequate, we are obligated
to increase them. An increase in loss reserves results in an increase in losses, reducing our net income for the
period in which the deficiency is identified. Accordingly, an increase in loss 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 cause volatility in our results of operations and could

materially reduce our level of 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 level of profitability or harm our financial condition,
which in turn could adversely affect our ability to write new business. 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. Additionally, catastrophe losses
incurred by residual markets or pooling mechanisms (such as wind pools) in certain states could trigger
assessments to the Company. Such assessments could be material and may not be recoupable, depending on the
applicable state mechanism.

The magnitude of loss from a catastrophe is a function of the severity of the event and the total amount of
losses from less severe

insured exposure in the affected area. Accordingly, we can sustain significant

18

State Auto 10-K High Res for Annual Report.pdf   20

3/9/11   9:32 PM

catastrophes, such as localized windstorms, when they affect areas where our insured exposure is concentrated.
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 severe thunderstorms, tornadoes
and hail, primarily in the Midwest and Texas, as well as earthquakes and hurricanes affecting the United States.
In the last three years, the largest catastrophe or series of catastrophes affecting STFC’s results of operations in
any one year were as follows: 2010 with losses from a series of spring storms including wind and hail in northern
Ohio and a rash of flood related claims in Nashville, Tennessee, both which affected our auto physical damage
results in both personal and business insurance auto lines resulting in approximately $22.2 million in pre-tax
losses; 2009 with losses from two winter storms in the South and Midwest resulting in approximately $41.1
million in pre-tax losses; and 2008 with losses from Hurricane Ike as it travelled through the Midwest resulting in
approximately $44.1 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 limits 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
of catastrophes on our business 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 reinsurance retention level.

Along with others in the industry, we utilize catastrophe models developed by third party vendors to help
assess and manage our exposure to catastrophe losses. Such models assume various conditions and probability
scenarios and use historical information about catastrophic events, along with detailed information about our
business. There are limitations to the usefulness of such models and they do not necessarily accurately predict
future losses. Climate change, to the extent it affects changes in weather patterns, could impact the frequency or
severity of weather events. Our ongoing catastrophe management efforts could negatively impact growth to the
extent constraints on property exposures are deemed necessary in certain territories.

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 adequately 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 establish and consistently follow appropriate underwriting guidelines;

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;

unanticipated changes or execution problems in our claim settlement practices;

changing driving patterns for auto exposures; changing weather patterns (including those which may be
related to climate change) 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, labor and other expenditures;

our ability to monitor and manage 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 premium reserves and competitiveness. In either event, our operating
results, financial condition and cash flows could be materially adversely affected.

TECHNOLOGY AND TELECOMMUNICATION SYSTEMS

Our business success and profitability depend,

in part, on effective information technology and
telecommunication systems. If we are unable to keep pace with the rapidly developing technological
advancements in the insurance industry, our ability to compete effectively could be impaired.

We depend in large part on our technology and telecommunication systems for conducting business and
processing claims. Our business success is dependent on maintaining the effectiveness of existing technology and
telecommunication systems and on their continued development and enhancement to support our business
processes and strategic initiatives in a cost effective manner. We recently began the development of a new claims
system. This effort will involve a significant commitment of resources over the next 24 months. The new system
is expected to add functionality, increase our claims efficiency and result in indemnity savings. In spite of our
best planning and efforts, it is possible that the system may not be developed within the planned time frame or
budget and/or that the expected benefits may not be realized upon implementation.

An ongoing challenge during system development and enhancement is the effective and efficient utilization
of current technology in face of a constantly changing technological landscape. There can be no assurance that
the development of current technology for future use will not result in our being competitively disadvantaged,
especially with those carriers that have greater resources. If we are unable to keep pace with the advancements

20

State Auto 10-K High Res for Annual Report.pdf   22

3/9/11   9:32 PM

being made in technology, our ability to compete with other insurance companies who have advanced
technological capabilities will be negatively affected. Further, if we are unable to effectively execute and update
or replace our key legacy technology and telecommunication systems as they become obsolete or as emerging
technology renders them competitively inefficient, our competitive position and/or cost structure could be
adversely affected.

BUSINESS CONTINUITY

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

including our information technology,
continuity and disaster recovery plans may not sufficiently address all contingencies.

Our business is highly dependent upon our ability to execute, in an efficient and uninterrupted fashion,
necessary business functions, such as Internet support and 24-hour claims contact centers, processing new and
renewal business, receiving and processing payment receipts 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 if our system 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, receive premium
payments, 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
and reputation.

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, which may result in a material adverse
effect on our financial position and results of operations.

REALIZATION OF DEFERRED INCOME TAX ASSETS

If some or all of our deferred tax assets will not be realized, we will be required to establish a valuation
allowance against the deferred income tax asset, which could have a material adverse effect on our results of
operations and financial condition.

Deferred tax assets and liabilities represent the tax effect of the differences between the financial statement
carrying value of existing assets and liabilities and their respective tax bases. At December 31, 2010, we have net
deferred federal income tax assets of $86.3 million, consisting of deferred tax assets of $177.2 million and
deferred tax liabilities of $90.9 million. Deferred tax assets are reduced by a valuation allowance if, based on the
weight of available evidence, it is more likely than not that some or all of the deferred tax assets will not be
realized. At December 31, 2010, we held no valuation allowance on our net deferred tax assets.

21

State Auto 10-K High Res for Annual Report.pdf   23

3/9/11   9:32 PM

The determination of the valuation allowance for deferred tax assets requires us to make certain judgments
and assumptions. In evaluating the ability to recover deferred tax assets, we consider all available evidence in
determining the realizability of the net deferred tax assets including loss carryback potential, past operating
results, existence of cumulative losses in the most recent years, projected performance of the business, future
taxable income, including the ability to generate capital gains, and prudent and feasible tax planning strategies. In
the event we determine that we most likely would not be able to realize all or part of our deferred tax assets in the
future, we would be required to establish a valuation allowance with a charge to earnings and/or other
comprehensive income in the period such determination is made. Our judgment and assumptions are subject to
change given the inherent uncertainty in predicting future performance or realizing tax planning strategies, which
is impacted by such things as severity and frequency of catastrophe losses, current premium rate environment,
investment market conditions, and planned loss and expense control initiatives that might not be realized.

REINSURANCE

Reinsurance may not be available, collectible or adequate to protect us against losses, or may cause us to

constrain the amount of business we underwrite in certain lines of business and locations.

We use reinsurance to help manage our exposure to insurance risks and to manage our capital. The
availability and cost of reinsurance are subject to prevailing market conditions, 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. Ceded reinsurance arrangements do not eliminate our obligation
to pay claims. As a result, we are subject to counterparty 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
and specialty lines of business tend to contract during periods of severe competition and price declines and
expand when market pricing allows an acceptable return. This can cause volatility in our premium revenues. Our
specialty insurance units, RED and Rockhill, market and underwrite commercial exposures through wholesale
brokers, program administrators and other specialty sources. The nature of such distribution channels reacting to
price competition may result in the movement of business and volatility of premium revenues.

The personal lines businesses are characterized by an auto underwriting cycle of loss cost trends. Driving
patterns, inflation in the cost of auto repairs and medical care and increasing litigation of liability claims are
some of the more important factors that affect loss cost trends. Inflation in the cost of building materials and

22

State Auto 10-K High Res for Annual Report.pdf   24

3/9/11   9:32 PM

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.

ECONOMIC CONDITIONS

The current and future difficult economic conditions can adversely affect our business, results of

operations and financial condition.

Current economic conditions and economic declines in future reporting periods could adversely impact our
business and results of operations. While the volatility of the economic climate makes it difficult for us to predict
the complete impact of economic conditions on our business and results of operations, our business may be
impacted in a variety of ways.

The economy has caused a number of consumers and businesses to decrease their spending, which may
impact the demand for our insurance products. For example, declining automotive sales and weaknesses in the
housing market generally impact the purchase of our personal auto and homeowners insurance products by
consumers and business insurance products by businesses involved in these industries. As unemployment rates
rise, there may be a tendency for the number of workers’ compensation claims to increase, as laid-off and
unemployed workers may seek workers’ compensation benefits to replace their lost health care benefits.
Similarly, uninsured and underinsured motorist claims may rise. Vacated homes and business properties pose
increased insurance industry risk.

Volatility and weakness in the financial and capital markets may negatively impact the value of our

investment portfolio.

We may be adversely affected by business difficulties, bankruptcies and impairments of other parties with
whom we do business, such as independent agents, key vendors and suppliers, reinsurers or banks, which
increases our credit risk and other counterparty risks. Bankruptcies among our current business insurance
customers can negatively affect our retention. Reductions in new business start-ups may negatively affect the
number of future potential business insurance customers.

In addition, departments of insurance, taxing authorities and other state and local agencies may seek to
impose or increase taxes, assessments and other revenue-generating fees in response to funding reductions
caused by economic downturns. These actions may increase the cost of doing business in these states. Economic
strains on states and municipalities could result in downgrades or defaults of certain municipal obligations.

In response to economic conditions, the United States federal government and other governmental and
regulatory bodies have taken action and may take additional actions to address such conditions. There can be no
assurance as to what impact such actions or future actions will have on the financial markets, economic
conditions or our Company.

In addition, government spending and monetary policies or other factors may cause the rate of inflation to
increase in the future. Inflation can have a significant negative 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.
Premium rates may prove to be inadequate due to low trend assumptions arising from the use of historical data.
Even when general inflation is relatively modest, price inflation on the goods and services purchased by
insurance companies in settling claims can steadily increase. Reserves may develop adversely and become
inadequate. Retentions and deductibles may be exhausted more quickly. Interest rate increases in an inflationary
environment could cause the values of our fixed income investments to decline.

23

3/9/11   9:32 PM

Adverse capital and credit market conditions may negatively affect our ability to meet unexpected

liquidity needs or to obtain credit on acceptable terms.

The capital and credit markets have been experiencing significant volatility and disruption. In some cases,
the markets have negatively affected the availability of liquidity and credit capacity. In the event that we need
access to additional capital to pay our operating expenses, make payments on our indebtedness, pay for capital
expenditures or fund acquisitions, our ability to obtain such capital may be constrained and the cost of any such
capital may be significant. Our ability to obtain additional financing will depend on numerous factors, such as
market conditions, the general availability of credit, the overall availability of credit to our industry, our credit
ratings and credit capacity, as well as lenders’ perception of our long- or short-term financial prospects. Our
access to funds may also be constrained if regulatory authorities or rating agencies take negative actions. If
certain factors were to occur, our internal sources of liquidity may prove to be insufficient and we may not be
able to successfully obtain additional financing on satisfactory terms.

DIVIDENDS

We may not be able to receive sufficient dividends from our insurance subsidiaries, and although we have
a history of paying cash dividends to our shareholders, there can be no assurance that we will continue to pay
cash dividends in the future.

We have a history of consistently paying cash dividends to our shareholders. However, the future payment
of cash dividends will depend upon a variety of factors, such as our results of operations, financial condition and
cash requirements, as well as the ability of our insurance subsidiaries to make distributions to STFC. State
insurance laws restrict the payment of dividends by insurance companies to their shareholders. In addition,
competitive pressures generally require insurance companies to maintain insurance financial strength ratings.
Such restrictions and other requirements and factors may affect the ability of our insurance subsidiaries to make
dividend payments to STFC. Limits on the ability of our insurance subsidiaries to pay dividends could adversely
affect our liquidity, including our ability to pay cash dividends to shareholders.

DISTRIBUTION SYSTEM

Our retail agents, who are part of the independent agency distribution channel, are our sole distribution
channel for our personal and business insurance segments. Our exclusive use of this distribution channel 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 in our personal and business insurance segments exclusively through
independent, non-exclusive insurance agents and brokers, 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. Throughout its history, the State Auto Group has supported the
independent agency system as our distribution channel. 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 decade 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 retail 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

24

State Auto 10-K High Res for Annual Report.pdf   26

3/9/11   9:32 PM

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 retail agents and to persuade them to promote and sell our
products, we may not be successful in executing 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 primary distribution system may place us at a disadvantage with consumers who prefer to purchase
insurance products online or through other alternative distribution channels.

REGULATION

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

growth.

We are subject to extensive regulation in the states in which we conduct business. This regulation is
generally designed to protect the interests of policyholders, as opposed to stockholders and other investors, and
limitations,
relates to authorization for lines of business, capital and surplus requirements,
underwriting limitations,
transactions with affiliates, dividend limitations (see “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.

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, some of which could be material
to our results of operations. 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.

25

State Auto 10-K High Res for Annual Report.pdf   27

3/9/11   9:32 PM

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, or repeal of McCarran-Ferguson Act
(which largely exempts the insurance industry from the federal antitrust laws), could significantly impact the
insurance industry and us.

The Federal Insurance Office was established in 2010 by the enactment of the Dodd-Frank Act. The Federal
Insurance Office will be a separate office within the United States Department of Treasury. While lacking
regulatory authority, the primary objectives of the Federal Insurance Office will be to monitor, collect data and
report on the insurance industry. It is not known how this federal office will coordinate and interact with the
NAIC and state insurance regulators.

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. For example, concerns over climate change may prompt
federal, state or local laws intended to protect the environment. Changes in the regulation of our business may
reduce our profitability, limit our growth or otherwise adversely affect our operations.

We could be adversely affected if our controls designed to assure compliance with guidelines, policies, and
legal and regulatory standards are ineffective. Our business is dependent on our ability to regularly engage in a
large number of insurance underwriting, claim processing, personnel and human resources, and investment
activities, many of which are complex. These activities often are subject to internal guidelines and policies, as
well as legal and regulatory requirements. No matter how well designed and executed, control systems provide
only reasonable assurance that the system objectives will be met. If our controls are not effective, it could lead to
financial loss, unexpected risk exposures or damage to our reputation.

Tax legislation initiatives or challenges to our tax positions could adversely affect our results of

operations and financial condition.

We are subject to the tax laws and regulations of the United States federal, state and local governments.
From time to time, various legislative initiatives may be proposed that could adversely affect our tax positions.
There can be no assurance that our effective tax rate or tax payments will not be adversely affected by these
initiatives. In addition, United States federal, state and local tax laws and regulations are extremely complex and
subject to varying interpretations. There can be no assurance that our tax positions will not be challenged by
relevant tax authorities or that we would be successful in any such challenge.

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 frequency or severity of claims.
The premiums we charge for our insurance products are based upon certain risk expectations. When 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. Furthermore, our reserve estimates do not take into consideration a major retroactive
expansion of coverage through legislative or regulatory actions or judicial interpretations.

26

State Auto 10-K High Res for Annual Report.pdf   28

3/9/11   9:32 PM

In particular, court decisions have had, and are expected to continue to have, significant impact on the
property and casualty insurance industry. Court decisions may increase the level of risk which insurers are
expected to assume in a number of ways, such as by eliminating exclusions, increasing limits of coverage,
creating rights in claimants not intended by the insurer and interpreting applicable statutes expansively to create
obligations on insurers not originally considered when the statute was passed. In some cases, court decisions
have been applied retroactively. Court decisions have also negated legal reforms passed by state legislatures.

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

There are concerns that the focus on climate change and global warming could effect court decisions or
result in litigation, including potential matters arising from federal, state or local laws intended to protect the
environment.

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.

LITIGATION

We may suffer losses from litigation, which could materially and adversely affect our operating results or

cash flows and financial condition.

As is typical in our industry, we face risks associated with litigation of various types, including disputes
relating to insurance claims under our policies, as well as other general commercial and corporate litigation.
Litigation is subject to inherent uncertainties and in the event of an unfavorable outcome in one or more litigation
matters, the ultimate liability may be in excess of amounts currently reserved and may be material to our
operating results or cash flows for a particular quarter or annual period and to our financial condition.

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 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. See “Regulation” in 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.

27

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, credit 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. Future increases in
interest rates could cause the values of our fixed income portfolios to decline, with the magnitude of the decline
depending on the duration of our portfolio. Individual securities in our fixed income portfolio are subject to credit
risk and default. Downgrades in the credit ratings of fixed maturities can have a significant negative effect on the
market valuation of such securities. For example, budget strains on certain states and local governments could
negatively affect the credit quality and ratings of their issued 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 of fixed income securities or a decline in the fair value of
equity securities could cause the investments in our pension plans to decrease, 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.

Changes in tax laws impacting marginal tax rates and/or the preferred tax treatment of municipal obligations
under current law, could adversely affect the market value of municipal obligations. Since a majority of our
investment portfolio is invested in tax-exempt municipal obligations, any such changes in tax law could
adversely affect the value of the investment portfolio. Additionally, any such changes in tax law could reduce the
difference between tax-exempt interest rates and taxable rates.

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, train, develop and retain talented, diverse 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. Talent management is a key consideration in our specialty insurance segment,
which requires specialized product underwriting, claims handling and risk management services and involves
distribution through channels other than our retail agents.

In addition, we must forecast the changing business environments (for multiple business units and in many
geographic markets) with reasonable accuracy and adjust hiring programs and/or employment levels accordingly.

Our failure to recognize the need for such adjustments, or the failure or inability to react appropriately on a
timely basis, could lead either to over-staffing (which would adversely affect our cost structure) or under-staffing
(impairing our ability to execute and effectively 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.

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, most recently the 2009 acquisition of the Rockhill Insurance Group by State Auto Mutual. It is
anticipated that we and State Auto Mutual will continue to pursue acquisitions or affiliations of other insurance
companies in the future.

Insurance company acquisitions and affiliations involving State Auto Mutual generally do not have a
material financial impact on State Auto Financial unless and until the target insurers are added to our Pooling
Arrangement, such as the addition of the Rockhill Insurance Group as of January 1, 2011.

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;

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. There is no assurance that any businesses
acquired in the future will be successfully integrated. Ineffective integration may adversely affect our results and
our ability to compete. Also, the acquired business may not perform as projected and anticipated cost savings and
other synergies may not be realized.

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 and our ability to compete. In May 2010, Standard & Poor’s
lowered our financial strength rating from A to A- with stable outlook primarily because of our recent operating
and financial results in comparison to our historical results, among other factors.

29

State Auto 10-K High Res for Annual Report.pdf   31

3/9/11   9:32 PM

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
currently have a rating from A.M. Best Company of A+ (Superior) (the second highest of A.M. Best’s 15 ratings)
with negative outlook. We may not be able to maintain our current A.M. Best or Standard & Poor’s ratings, or
our current ratings from other rating agencies.

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, 2010, our parent company owned approximately 63% 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,
producer relationships, 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 personal and business insurance customers, but also for independent agents and brokers to market and
sell our products. Our specialty insurance segment faces competitors attempting to sell their products through the
distribution system of wholesale brokers, program administrators and other specialty sources. 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 efficiently execute and 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.

The trading price of our common stock may fluctuate substantially due to a variety of factors, some of
which may not be related to our operating performance and are beyond our control. Such factors include, but are
not limited to, the following: volatility and 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 2. Properties

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

Item 3. Legal Proceedings

We are involved in a number of lawsuits, and may become involved in other potential litigation, arising in
the ordinary course of our business. Generally, our involvement in a lawsuit involves defending third-party
claims brought against our insureds in our role as liability insurer or against us as a principal of surety bonds, as
well as defending policy coverage claims brought against us. We consider all lawsuits relating to such insurance
claims in establishing our loss and loss adjustment expense reserves.

The following describes the significant pending legal proceedings, other than ordinary routine litigation
incidental to our business, to which State Auto Financial or any of its subsidiaries is a party or to which any of
our property is subject:

In December 2010, a putative class action lawsuit (Kelly vs. State Automobile Mutual Insurance Company,
et al.) was filed against State Auto Financial, State Auto P&C and State Auto Mutual in state court in Ohio.
In this lawsuit, plaintiffs allege that the State Auto Group has engaged, and continues to engage, in
through one or more related
deceptive practices by failing to disclose to plaintiffs the availability,
companies, of insurance policies providing for identical coverage and service as those policies purchased by
plaintiffs but at a lower premium amount. Plaintiffs are seeking class certification and compensatory and
punitive damages to be determined by the court and restitution and/or disgorgement of profits derived from
plaintiffs and the alleged class. We filed a motion to dismiss on March 1, 2011, and it remains pending. We
believe our practices with respect to pricing, quoting and selling our insurance policies are in compliance
with all applicable laws, deny any and all liability to plaintiffs or the alleged class, and intend to vigorously
defend this lawsuit.

We accrue for a litigation-related liability, other than insurance claims, when it is probable that such a
liability has been incurred and the amount of the loss can be reasonably estimated. Based on currently available
information known to us, we believe that our reserves for these litigation-related liabilities are reasonable and
that the ultimate outcomes of any pending matters are not likely to have a material adverse effect on our
consolidated financial position or results of operations. However, regarding the putative class action litigation
described above, it is not currently possible to predict the legal outcome of this litigation or its impact on the
future development of claims and litigation relating to similar claims. Any such development will be affected by
future court decisions and interpretations. Because of these uncertainties, additional liabilities may arise in
amounts in excess of our currently held reserves. In addition, our estimate of ultimate claims and claim
adjustment expenses may change. These additional liabilities or increases in estimates, or a range of either,
cannot now be reasonably estimated and could result in income statement charges that could be material to our
results of operations in future periods.

Additionally, our insurance subsidiaries may be impacted by adverse regulatory actions and adverse court
decisions where insurance coverages are expanded beyond the scope originally contemplated in our insurance
policies. We believe that the effects, if any, of such regulatory actions and published court decisions are not
likely to have a material adverse effect on our financial position or results from operations.

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. This discussion should be read in conjunction with the consolidated financial statements and notes
thereto included in Item 8 of this Form 10-K and the narrative description of our business contained in Item 1 of
this Form 10-K.

OVERVIEW

State Auto Financial is a property and casualty insurance holding company. Our insurance subsidiaries are
part of the State Auto Group and Pooling Arrangement described below. The State Auto Group markets a broad
line of property and casualty insurance products in all 50 states and the District of Columbia exclusively through
independent insurance agencies, which include retail agents and wholesale brokers. Our Pooled Companies are
rated A+ (Superior) by the A.M. Best Company.

State Auto Financial’s principal subsidiaries are State Auto P&C, Milbank, Farmers and SA Ohio, each of
which is a property and casualty insurance company, and Stateco, which provides investment management
services to affiliated insurance companies.

Prior to January 1, 2011, we operated our business in three reportable segments: personal insurance,
business insurance (collectively the “insurance segments” or “our insurance segments”) and investment
operations. The three segments reflected the manner in which we managed our business and reported our results
internally to our principal operating decision makers. The personal insurance segment provides primarily
personal auto and homeowners to the personal insurance market. The business insurance segment provides
primarily commercial auto, commercial multi-peril, fire & allied lines, other & 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 our invested assets. In
2010, the State Auto Group began writing new commercial specialty business through RED, which allowed us to
offer insurance coverages in the program and alternative risk markets for business products such as general
liability, commercial auto, workers’ compensation and property. In 2010, the financial results of business written
through RED were included in our business insurance segment results.

With the acquisition of the Rockhill Insurance Group and the build out of RED, in 2010, management
focused on assessing and positioning a realignment of our internal organization, including people, processes and
compensation reward programs, to be more strategic in the personal, business and specialty insurance markets.
Considering these internal changes, and with the inclusion of the Rockhill Insurers into the Pooling Arrangement
as of January 1, 2011, our reportable insurance segments will change from personal and business insurance to
personal insurance, business insurance and specialty insurance, aligning how these insurance segments report to
our principal operating decision makers.

We evaluate the performance of our insurance segments using industry financial measurements determined
based on SAP, and certain measures determined under GAAP. We evaluate our investment operations segment
based on investment returns of assets managed. Financial information about our segments for 2010 is set forth in
this Item 7 and in Note 16 to our consolidated financial statements included in Item 8 of this Form 10-K.

EXECUTIVE SUMMARY

In order to improve our operating and financial results, we focus on four performance drivers – rational

growth, underwriting profit, risk management, and capital management.

35

State Auto 10-K High Res for Annual Report.pdf   37

3/9/11   9:32 PM

Rational Growth

Our growth in 2008 and 2009 outperformed the industry, which generally contracted, and based on
preliminary data now available to us, we believe our premium growth again outperformed the industry in 2010.
We consider rational growth to be premium growth that matches or exceeds the premium growth rates of
designated peer property and casualty insurance companies, as well as the property and casualty insurance
industry as a whole, while still considering underwriting profit, risk management, and capital management.

There are primarily two ways we grow our business. The first way is referred to as organic growth. This
means we either sell more policies or increase the price of our product. Ideally, we will accomplish both
simultaneously. Organic growth is challenging, especially in a stagnant economy and well-capitalized industry. If
the price of our product is too high, customers may go elsewhere, and so the desired premium increases could be
offset by a reduction in policy count. If the price is too low, we could increase our policy count at the risk of
surrendering profit.

We also seek growth in ways other than price. When we are faced with untenably low prices from our
competition, our goal is to remain an attractive market to our insureds, retail agents and wholesale brokers by
stressing the strengths we bring to the marketplace, such as our product offerings and innovation; underwriting
criteria; quality of service to insureds, retail agents and wholesale brokers; relationships with our retail agents
and wholesale brokers; prompt and fair claims handling and settlement; financial stability; and technology,
making us a preferred business partner.

Organic growth in our business insurance segment, other than our RED book of business, has been more
difficult for us to achieve than growth in our personal insurance segment. The primary reasons are the continued
impact of the economy on premium bases and our commitment to underwriting. The business lines segment has
been extremely competitive. Generally, business lines premiums and coverages are higher per policy than
personal lines. Until the market accepts adequately priced product, we will be challenged to grow our standard
business insurance book. However, we are seeking to balance our traditional underwriting discipline with new
products and pricing tools that support the production of profitable new business. Our industry is characterized
by its cyclical nature. During the current phase in the cycle, we are willing to sacrifice premium growth in our
business lines in favor of achieving underwriting profitability.

While organic growth in the standard business insurance market has been difficult, we are competing
effectively in the personal lines market. Our retail agents are finding attractive sales opportunities for auto and
homeowners business. In addition, because we are heavily cross-sold in personal lines and continue to experience
strong retention, we are well positioned to benefit from this trend.

Alternatively, we can grow by acquiring other companies and their distribution points, entering new states,
offering new products, appointing new agents or offering our products through alternative distribution channels.
This can be generally labeled as growth through merger and acquisition. Since STFC went public in 1991, the
State Auto Group has successfully acquired six insurance groups comprising more than a dozen companies.
Acquisition, as opposed to organic growth, has several advantages. It can be a practical, efficient way to leverage
the acquired company’s existing channel relationships when introducing our products and services into a new
state or new markets, rather than appointing one agent at a time, which can be expensive and difficult. Often
acquisitions bring with it needed talent and competencies to the larger State Auto Group. An acquisition though,
is also a major investment of capital. Immediate consequences of a poor acquisition choice can include
overstaffing, incompatible automation systems and an ineffective distribution force.

We believe it is important to have processes and talent in place to grow both organically and through
mergers and acquisitions. In 2009, our parent, State Auto Mutual, took a major growth step by acquiring the
Rockhill Insurance Group, a specialty property and casualty insurance group, serving both the standard and
excess and surplus lines insurance markets, whose product lines include commercial auto, property, bonds
(surety and fidelity) and general liability. RED acts as a managing general underwriter for a variety of property
and casualty coverages in the program and alternative risk markets. The insurers owned by RTW provide

workers’ compensation coverage. While our top line growth in business insurance benefited from RED in 2010,
we will see additional benefit from the other specialty businesses of Rockhill and RTW, when the financial
results of these units are incorporated into our pooled results beginning January 1, 2011. We believe the growth
and profit potential are excellent and provide diversification to our current product lines.

Underwriting Profit

We have long been known as an insurance company that produces an underwriting profit. Our combined
ratio, however, has exceeded 100% for the last three years. It is critical to us that we return homeowners to
underwriting profitability. Homeowners insurance is our second largest product concentration, after standard
auto. A multi-year effort to implement solutions has produced an aggressive insurance to value program that
audits policy coverage against the actual value of the property. We have also implemented separate, mandatory
wind and hail deductibles for properties in select states and by-peril rating for homeowners in key states. By-peril
rating calculates a separate premium for each peril and allows us to price more effectively for weather
differences, which is the leading cause of homeowners’ losses. Our claim handling has become more specialized,
with the addition of dedicated large and small property claim handlers and the formation of a catastrophe claim
team, lessening our dependency on independent adjusters. We are also continuing our efforts to diversify
geographically, with particular emphasis on those areas less prone to catastrophic property losses. Underwriting
results in homeowners have improved in 2010.

Pricing the property and casualty insurance product has become a sophisticated science, and to that end we
have made significant investment in our actuarial and financial teams, adding depth and talent to these important
functions. We are dedicated to cost-based pricing, with each line of business priced to generate a profit. We
implement periodic rate changes throughout our states.

Underwriting profitably requires more than sensible pricing, coverage enhancements and discerning risk
evaluation. By reducing the per policy costs of operating our business, we increase the profit margin. In early
2009, we began a restructuring of our field and claims operations. We are seeing productivity and expense ratio
improvements. The restructuring meant a reduction in both the personal and commercial lines staffs and an
increase in our information technology and claims personnel. While difficult for us, these reductions were
necessary, and we believe we handled the reductions with sensitivity, including providing severance packages
and retirement incentives to those associates affected.

Changes currently underway in our claim organization are expected to positively impact indemnity payout,
improve service and reduce costs. We have already reduced salvage yard vendor fees through negotiation with
vendors. A new auto physical damage unit has significantly reduced independent adjuster expenses and improved
indemnity benefits on auto physical damage claims. The expansion of our house counsel operation not only
contributes to a lower loss ratio, but also improves service.

Risk Management

The objective of our enterprise risk management program is to help identify, understand, communicate and
assure satisfactory mitigation or exploitation of risks associated with our business. Numerous risks are addressed,
including a variety of underwriting, operational, market, credit and strategic risks. All of our business units play
important roles in risk identification and in developing and executing risk mitigation strategies.

An internal, multi-disciplined team was formed in 2010 to address our geographic spread of risk and
catastrophe loss exposure. Weather related catastrophes, including localized wind and hail storms, have been an
onerous variable in our profitability formula in recent years, contributing to volatility in our financial results. We
remain committed to taking steps to more effectively manage our catastrophe exposures and improve our
geographic diversification. The combination of walking away from business in high risk or highly concentrated
areas, while growing more aggressively in areas with lower property exposures or in less catastrophe-prone areas,

37

State Auto 10-K High Res for Annual Report.pdf   39

3/9/11   9:32 PM

or in areas where the catastrophe risk is uncorrelated to our existing footprints, are effective approaches to spread
risk. Our merger and acquisition strategy also contributes to spread of risk. For example, the RED, Rockhill and
RTW operations provide an additional measure of product and geographical diversification.

Catastrophe exposure management focuses on the perils of hurricane, earthquake, severe thunderstorms,
tornadoes and hail. Computer modeling is used to project estimates of potential losses from these events. Such
modeling is an important element of designing our property reinsurance programs. The results of hurricane
modeling affect our risk appetites across six relevant geographic zones: Texas, the Gulf States, Florida, the
Southeast, the Mid-Atlantic, and the Northeast. Modeling for severe thunderstorms, tornadoes and hail has
helped us identify areas of Midwest property concentrations for reduction or constraint, as well as areas with
lower and/or uncorrelated exposure to target for growth.

Risk management is also relevant to our business operations. In 2010, State Auto Mutual completed the
construction of a new data center located more than 20 miles from our corporate headquarters, and we are in the
process of migrating many of our IT functions to it. Its state-of-the-art design allows it to function securely under
work load and environmental pressures. The commitment to make our data centers and processing systems
secure and dependable is ongoing and, given the critical nature of information technology, will continue to
remain a risk management priority.

Capital Management

In capital management, our number one goal remains preserving capital and enhancing liquidity in order to
maintain a financial strength rating from A.M. Best that will enable us to maintain our preferred partnership
status with our insureds, retail agents and wholesale brokers. STFC has paid a dividend every quarter since its
inception in 1991, and has never lowered that dividend. We have maintained a debt to capital ratio that reinforces
our strong capital structure.

Members of the State Auto Group pay a portion of the premiums received to reinsurers in exchange for
reinsuring a portion of their exposures. This is done primarily to reduce net liability on individual risks or for
individual loss occurrences, including catastrophic losses. We maintain reserves for the eventual payment of
losses and loss expenses for both reported claims and IBNR, based on management’s best estimate at a given
point in time. Although management uses many resources to calculate reserves, there is no precise method for
determining the ultimate liability. Our objective is to set reserves that reasonably approximate the ultimate
liability for insured losses and loss expenses. We regularly review and adjust loss reserves as appropriate.

Our disciplined investment strategy emphasizes the quality of our investment grade fixed maturity portfolio
and an internally managed, diversified equity portfolio. We have diversified our equity portfolio, utilizing outside
managers to invest in U.S. small-cap equities and international equity funds. This was designed to achieve
greater total return over time with reduced volatility. We suffered investment losses in the broad-based and
dramatic market decline in 2008, but we have since more than recovered those losses in the healthier markets of
2009 and 2010. In our opinion, a diversified portfolio heavily weighted in investment grade bonds, coupled with
a diversified equity portfolio, is the right strategy for most market cycles.

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.

38

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 in accumulated other comprehensive income
(loss), 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-temporarily impaired
(“OTTI”), an assessment that requires significant management judgment regarding the evidence known. Such
judgments could change in the future as more information becomes known which could negatively impact the
amounts reported herein. We consider the following factors when assessing our equity securities and other
invested assets for OTTI: (1) the length of time and/or the significance of decline below cost; (2) our ability and
intent to hold these securities through their recovery periods; (3) the current financial condition of the issuer and
its future business prospects; and (4) the ability of the market value to recover to cost in the near term. We
recognize OTTI charges on our externally managed small-cap equity portfolio and a segment of our large-cap
portfolio, as we are unable to make the assertion regarding our intent to hold these securities that are currently
valued below cost until recovery in the near term. When an equity security or other invested asset 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 reversed for subsequent recoveries
in fair value. Future increases or decreases in fair value, if not other-than-temporary, are included in accumulated
other comprehensive income (loss).

We also consider the following factors when assessing our fixed maturity investments for OTTI: (1) the
financial condition of the issuer including receipt of scheduled principal and interest cash flows; (2) our intent to
sell; and (3) if it is more likely than not that we will be required to sell the investments before recovery. When a
fixed maturity has been determined to have an other-than-temporary impairment, the impairment charge is
separated into an amount representing the credit loss, which is recognized in earnings as a realized loss, and the
amount related to non-credit factors, which is recognized in accumulated other comprehensive income (loss).
Future increases or decreases in fair value, if not other-than-temporary, are included in accumulated other
comprehensive income (loss).

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 premiums to be earned, losses and loss expenses expected to be incurred, and certain other
costs expected to be incurred as premium is earned. Future changes in estimates, the most significant of which is
expected losses and loss adjustment expenses, that indicate a reduction in expected future profitability may result
in unrecoverable deferred acquisition costs. We have not recorded any significant changes in estimates for the
years ended December 31, 2010, 2009 and 2008, respectively.

Losses and Loss Expenses Payable

Our loss reserves reflect all unpaid amounts for claims that have been reported, as well as for IBNR claims.

Our loss reserves are not discounted to present value.

Loss reserves are management’s best estimates (“MBE”) at a given point in time of what we expect to pay
to settle all claims incurred as of that date based on known facts, circumstances and historical trends. Loss
reserves at the individual claim level are established on either a case reserve basis or formula reserve basis

39

State Auto 10-K High Res for Annual Report.pdf   41

3/9/11   9:32 PM

depending on the type and circumstances of the loss. The case reserve amounts are determined by claims
adjusters based on our reserving practices, which take into account
the circumstances
surrounding each claim and applicable policy provisions. The formula reserves are based on historical data for
similar claims with provision for changes caused by inflation. Case reserves and formula 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 reserve is to develop an
estimate of the ultimate losses and allocated loss expenses incurred, and subtract all amounts already paid or held
as case or formula reserves.

the type of risk,

The determination of ultimate losses 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 reserves represent an estimate at a given point in time based on many variables including historical
and statistical
legal developments, storm loss estimates and economic conditions.
Although we consider many different sources of information, as well as a number of actuarial methodologies to
estimate our loss reserves, 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 our loss reserves.

We use a number of different methodologies to estimate the IBNR component of our loss reserves. Our loss
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. In general, 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-tail business, 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 (formula 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 the paid method
exclude case reserve estimates, so only paid losses are utilized. With this method, 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

40

State Auto 10-K High Res for Annual Report.pdf   42

3/9/11   9:32 PM

extent that the reporting pattern influences 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 less mature accident 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 number. Similarly, the
incurred loss severities are projected to an ultimate value. The ultimate incurred count is multiplied by the
ultimate incurred severity, for each accident year, to arrive at the ultimate incurred loss. Finally, as with the other
loss development methods, an estimate of the IBNR reserve is calculated by subtracting the reported losses from
the estimated ultimate losses.

Long-Tail Business: Reserve estimates for long-tail business use the same methods listed above 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 may 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 premiums, 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 limited or too volatile for
other projection methods. 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 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 are generally correlated 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,
along with supplemental information such as 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 of our underwriting and claims functions.

Reserve ranges provide a quantification of the variability in the loss reserve projections. The primary
determinant in estimating the loss reserve range boundaries are the variances measured within the historical
reserving data for the various lines of business. MBE of loss reserves considers the expected variation to
establish an appropriate position within a range. MBE loss and ALAE reserves for the STFC Pooled Companies’

41

State Auto 10-K High Res for Annual Report.pdf   43

3/9/11   9:32 PM

share of the Pooled Companies’ reserves at December 31, 2010, was $884.1 million, within an estimated range of
$811.4 million to $904.7 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 other loss and loss expenses payable tables
included elsewhere within this Form 10-K.)

The potential impact of the loss reserve variability on net income can be illustrated using the range end
points and carried reserve amounts listed above. For example, if ultimate losses reach a level corresponding to
the high point of the range, $904.7 million, the reserve increase of $20.6 million corresponds to an after-tax
decrease of $13.4 million in net income, assuming a tax rate of 35%. Likewise, should ultimate losses decline to
a level corresponding to the low point of the range, $811.4 million, the $72.7 million reserve decrease would add
$47.3 million of after-tax net income. The loss reserve range noted above represents a range of reasonably likely
reserves, not a range of all possible reserves. Therefore, the ultimate losses could reach levels corresponding to
reserve amounts outside the range provided.

An important assumption underlying the loss 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, 2010, other & product 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
increase 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 & product liability is an
increase of $76.3 million on reserves, or a $49.6 million reduction to net income, assuming a tax rate of 35%.
Inflation changes have much more impact on the longer tail commercial lines like other & product liability and
workers’ compensation, and much less impact on the shorter tail personal lines’ reserves.

In addition to establishing loss reserves, as described above, we establish reserves for ULAE. Historical
patterns of paid ULAE relative to paid loss are analyzed along with historical claim counts including claims
opened, claims closed, and claims remaining open. The product of this analysis is an estimate of the relationship,
or ratio, between ULAE and loss underlying the current loss reserves. This ratio is applied to the current
outstanding loss reserves to estimate the required ULAE reserve. Consequently, this component of the loss
expense reserve has a proportional relationship to the overall claim inventory and held loss reserves. The method
assumes that the underlying claims process and mix of business do not change materially over time.

The property and casualty industry has experienced significant loss from claims related to asbestos,
environmental remediation, product liability, mold and other mass torts. Asbestos reserves are $1.5 million, and
environmental reserves are $8.8 million, for a total of $10.3 million, or 1.2% of net losses and loss expenses
payable. Asbestos reserves decreased $0.5 million and environmental reserves increased $0.2 million from 2009.
Because we have insured primarily product retailers and distributors, we do not expect to incur the same level of
liability, particularly related to asbestos, as companies that have insured manufacturing risks.

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.

The State Auto Group has a defined benefit pension plan and a postretirement health care plan covering
substantially all employees hired prior to January 1, 2010 (collectively “the benefit plans”). Several factors,
which attempt to anticipate future events, are used in calculating the expense and liability related to the benefit
plans. Key factors include assumptions about the expected rates of return on plan assets, discount rates, and
health care cost trend rates. We consider market conditions, including changes in investment returns and interest
rates, in making these assumptions. 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.

To calculate the State Auto Group’s December 31, 2010 benefit obligation for each of the benefit plans, we
used a discount rate of 5.50% based on an evaluation of the expected future benefit cash flows of our benefit
plans used in conjunction with the Citigroup Pension Discount Curve at the measurement date. A lower discount
rate results in, all else being equal, a higher present value of the benefit obligation. To calculate our benefit
obligation at December 31, 2010 and net periodic benefit cost for the year ended December 31, 2011, a discount
rate of 5.50% and an expected long-term rate of return on plan assets of 8.00% were used. We selected an
expected long-term rate of return on our plan assets by considering the mix of investments and stability of
investment portfolio along with actual investment experience during the lifetime of the plans. Our assumptions
regarding the discount rate and expected return on plan assets could have an effect on the amounts related to our
benefit obligations and net periodic benefit cost depending on the degree of change between reporting periods.

The following table sets forth an illustration of variability with respect to the discount rate on our
December 31, 2010 benefit obligation and expected net periodic benefit cost for the year ending December 31,
2011, along with the variability of the expected return on plan assets to our expected net periodic benefit cost for
the year ending December 31, 2011. Holding all other assumptions constant, sensitivity to changes in any one of
our key assumptions are as follows:

The accumulated benefit obligation (“ABO”) of a defined benefit pension 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 projected benefit obligation
(“PBO”) is the ABO plus a factor for future compensation levels. The ABO, which considers current
compensations level only, provides information about the obligation an employer would have if the plan were
discontinued at the measurement date. At December 31, 2010, the ABO and PBO were $258.3 million and
$282.8 million, respectively. At December 31, 2010, the fair value of the assets of our defined benefit pension
plan was $219.6 million, which resulted in an underfunded status within our balance sheet of $63.2 million. On a
cash flow basis, we target an annual contribution level that meets at least the targeted normal cost of the plan, as
defined by ERISA. Currently, we expect to make a cash contribution to the pension plan up to $15.0 million in
2011.

Our unfunded status on our pension plan increased from $52.1 million at December 31, 2009, to $63.2
million at December 31, 2010. Primarily influencing this increase are unrecognized gains and losses arising from
factors including a decrease in the discount rate and expected to actual demographic changes, such as retirement
age, mortality, turnover, and rate of compensation increases. The cumulative unrecognized actuarial loss is
systematically recognized as an increase in net periodic cost over the average future service period of active
participants. Additional factors influencing this increase are as follows: (1) actual return on our plan assets was a
gain of $24.0 million compared to an expected return of $17.3 million for a net decrease to our obligation and
unrecognized actuarial loss of approximately $6.7 million; and (2) a $2.4 million curtailment gain which reduced
our obligation and unrecognized actuarial loss.

In November 2009, we announced to our employees a one-time election to select between two retirement
benefit options: to either continue participation in the existing defined benefit pension plan with no changes; or to
choose a new defined contribution plan in which we automatically contribute a percentage of the employee’s
annual income resulting in a freeze to the employee’s existing accrued defined pension benefit. On May 31,
2010, employees’ elections were finalized which resulted in a $2.4 million curtailment gain on this date.

Our unfunded status on our postretirement medical plan (“retiree med plan”) increased from $92.8 million at
December 31, 2009 to $116.7 million at December 31, 2010. Influencing this increase are unrecognized net
actuarial gain and loss adjustments arising from a decrease in the discount rate, as well as demographic changes
and expected to actual claims experience, which at December 31, 2010 had the effect of increasing our obligation
and unrecognized actuarial loss.

See Note 10, “Pension and Postretirement Benefit Plans” to our consolidated financial statements included

in Item 8 of this Form 10-K for further disclosures regarding our pension and postretirement benefit plans.

Deferred Income Taxes

Deferred income tax assets and liabilities represent the tax effect of the differences between the financial
statement carrying value of existing assets and liabilities and their respective tax basis. Deferred tax assets are
evaluated periodically by management to determine if they are realizable, requiring us to make certain judgments
and assumptions. In evaluating the ability to recover deferred tax assets, we consider all available evidence,
including loss carryback potential, past operating results, existence of cumulative losses in the most recent years,
projected performance of the business, future taxable income, including the ability to generate capital gains, and
prudent and feasible tax planning strategies. If, based on available information, it is more likely than not that the
deferred income tax asset will not be realized,
then a valuation allowance must be established with a
corresponding charge to net income and/or accumulated comprehensive income (loss). No valuation allowance
was held by us at December 31, 2010.

POOLING ARRANGEMENT

The STFC Pooled Companies and the Mutual Pooled Companies participate in a quota share reinsurance
pooling arrangement referred to as the “Pooling Arrangement.” Under the Pooling Arrangement, State Auto
Mutual assumes premiums, losses and expenses from each of the remaining Pooled Companies and 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 2008, we made the following changes to the Pooling Arrangement (the “2008 pooling changes”):

•

•

•

•

•

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; and

Included voluntary assumed reinsurance from parties affiliated with State Auto Mutual.

In 2010, we made the following changes to the Pooling Arrangement (the “2010 pooling changes”):

•

•

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

Included voluntary assumed reinsurance from third parties unaffiliated with the Pooled Companies that
was assumed on or after January 1, 2009 by State Auto Mutual.

In conjunction with the 2010 pooling changes, the STFC Pooled Companies received $3.7 million in cash
from the Mutual Pooled Companies, for net insurance assets transferred on January 1, 2010. The following table
sets forth the impact on our balance sheet at January 1, 2010, relating to the 2010 pooling changes:

It is not management’s intention to recommend an adjustment to the STFC Pooled Companies’ 80%
participation level
the Pooling
in the foreseeable future. Under applicable governance procedures,
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.

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 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.
This has the effect of providing each of our Pooled Companies with a similar mix of pooled property and
casualty insurance business on a net basis.

2010 Highlights

Our 2010 pre-tax income was $24.5 million compared to pre-tax losses of $12.8 million and $75.1 million
in 2009 and 2008, respectively. Revenues increased to $1,355.1 million in 2010 from $1,256.9 million and
$1,181.9 million in 2009 and 2008, respectively, while expenses increased to $1,330.6 million in 2010 from
$1,269.7 million and $1,257.0 million in 2009 and 2008, respectively. The following highlights significant
factors that impacted 2010 results as compared to 2009 and 2008:

Earned premiums in 2010 were $1,257.2 million compared to $1,176.5 million and $1,126.0 million in
2009 and 2008, respectively. This growth was primarily driven by a combination of an increase in the
level of exposures written and the result of rate increases in our personal lines.

• We recognized $3.6 million of OTTI on our investment portfolio during 2010 compared to $9.0 million

and $39.3 million in 2009 and 2008, respectively.

•

•

•

•

Net realized gains on investments, excluding OTTI, were $18.5 million in 2010, compared to $3.8
million and $2.9 million in 2009 and 2008, respectively. Included in the 2010 net realized gains on
investments was $3.9 million related to the sale of our nonstandard automobile subsidiary, SA
National.

On December 31, 2010, we sold SA National to a third party for $14.0 million plus a contingent earn-
out. In deciding to sell SA National, we considered those businesses core to our long-term strategy and
concluded that the nonstandard auto market was no longer a strategic fit for us. In 2010, SA National
wrote approximately $37.0 million in direct written premiums through our independent agents in 21
states, with 80% (or approximately $30.0 million) retained by us under our Pooling Arrangement. We
will continue to write SA National renewal business until such business is transitioned from our system
to the buyer’s system, which should occur during the second quarter of 2011. See “Reinsurance
Arrangements” section included in this Item 7.

Catastrophe losses for 2010 were $99.0 million (7.9 loss ratio points) compared to $90.3 million (7.7
loss ratio points) and $156.1 million (13.9 loss ratio points) for the same 2009 and 2008 periods,
respectively. The 2008 catastrophe losses included catastrophe losses related to Hurricane Ike, which
delivered tropical storm force winds to Texas and three of our largest states, Ohio, Kentucky and
Indiana, accounting for $44.1 million of losses or 3.9 loss ratio points.

Our non-catastrophe losses for 2010 were $790.6 million (62.9 loss ratio points) compared to $753.0
million (64.0 loss ratio points) and $690.6 million (61.3 loss ratio points) for the same 2009 and 2008
periods, respectively.

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.

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 acquisition costs, see
“Critical Accounting Policies—Deferred Acquisition Costs” section included in this Item 7.

Charges related to the restructuring of our field and claims operations, as well as those recorded due to the
North Carolina Beach Plan write-off in 2009, contributed to the difference between our GAAP expense ratio and
our SAP expense ratio. The restructuring differences relate mainly to the timing of the recognition of employee

50

State Auto 10-K High Res for Annual Report.pdf   52

3/9/11   9:32 PM

termination benefits. SAP requires us to estimate and immediately recognize the entire estimated costs related to
severance, while GAAP requires similar estimated costs to be recognized ratably over the remaining service
period of the employees impacted. The write-off in 2009 related to the North Carolina Beach Plan was included
in the other expenses line item in the accompanying consolidated statements of income, and was therefore not
included in the computation of the GAAP expense ratio.

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 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. Unearned premiums are
reflected on our balance sheet as a liability and represent our obligation to provide coverage for the unexpired
term of the policy.

The following table sets forth the reconciliation of the one-time impact on net written premiums for the year
ended December 31, 2010, of the unearned premiums transferred to the Mutual Pooled Companies on January 1,
2010, in conjunction with the 2010 pooling changes:

Personal Insurance Segment Revenue

Our personal insurance segment consists primarily of auto and homeowners products, with personal auto
representing 39%, 41% and 38% of our total consolidated net written premiums in 2010, 2009 and 2008,
respectively. We believe introducing new products, leveraging predictive modeling capabilities and making it
easier for our agents and policyholders to do business with us through enhanced systems and easier to use
technologies will enable us to strategically grow our personal lines business in desired geographic locations.

CustomFit SM, our standard auto product, provides additional quoting opportunities by allowing our agents to
tailor policies to fit the insured’s needs. Further expanding our product portfolio, in the fourth quarter of 2009 we
introduced our new homeowners CustomFit product which employs predictive modeling and by-peril rating,
allowing us to target business with expected long-term profit potential. Compared to the traditional method of
using fire as the main basis for rating, by-peril rating uses multiple perils (such as wind, hail and water) in the
rating process designed to provide a more accurate and adequate rate. Our CustomFit homeowners product has
now been deployed in eight states and future deployment is planned for our remaining states.

Our emphasis in personal insurance continues to be homeowners profitability. In addition to rate increases
and the introduction of our CustomFit homeowners product, we are aggressively evaluating and monitoring
unprofitable agencies, which may include the review of an agency’s existing policies, implementation of tighter
new business and renewal guidelines for that agency, and the application of other loss mitigation tools for use by
that agency, all with the purpose of improving operating results at the agency level. We are continuing with a
proactive insurance to value program, which is designed to have our insureds maintain an amount of coverage
sufficient to replace their home and contents in the case of a total loss consistent with our loss settlement
practices. In addition, we have implemented wind and hail deductibles in 15 states and are deploying strategies to
provide greater spread of risk for our homeowners line.

Over the years, we have focused on improved technology interfaces with our agents and policyholders. This
has included enhancing our personal lines sale portal netXpress SM for our agents, including increasing the
number of integration points to our rating engine thus eliminating duplicate entry for agents. These actions have
resulted in increased levels of quote activity by our agents. For our policyholders, we have increased the number
of electronic bill pay options, including 24 x 7 online capability, along with introduction of claim reporting
technology.

The following table sets forth 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, 2010, 2009 and
2008. The one-time impacts of the 2010 and 2008 pooling changes have been excluded from 2010 and 2008 to

Standard personal auto net written premiums for the year ended December 31, 2010 increased 6.8%
compared to the same 2009 period. Rate increases contributed to approximately half of this premium growth,
while the State Auto Group’s expansion of its operations within four of our newer states, Texas, Colorado,
Arizona and Connecticut, contributed to the balance. Net written premiums for the year ended December 31,
2009 increased 15.4% compared to the same 2008 period. The expansion into Texas, Colorado, Arizona and
Connecticut contributed to approximately 5 points of this growth in 2009, and rate increases also contributed to
this growth. While growth continues to be strong, we are experiencing a slowdown in new business and a lower
issue-to-quote ratio which we attribute to the impact of our rate increases.

Nonstandard auto net written premiums for the year ended December 31, 2010 decreased 26.5% compared
to the same 2009 period. Approximately two-thirds of this decline was due to the inclusion of the nonstandard
auto business in the Pooling Arrangement effective January 1, 2010 (20% of this business is ceded to the Mutual
Pooled Companies). In August 2010, we announced that STFC had entered into an agreement to sell our
nonstandard automobile insurance subsidiary, SA National, which resulted in a slowdown of new business
submitted by our agents. The decline in net written premiums was also due to certain underwriting actions taken
in 2009 and 2010 that included increasing rates and terminating certain agencies that had failed to consistently
perform to our expectations. These actions, coupled with the impact of general economic conditions, continued to
result in a reduction of nonstandard auto business. The actions taken in 2009 also contributed to the decline in net
written premiums for the year ended December 31, 2009 of 10.7% compared to the same 2008 period.

Homeowners net written premiums for the year ended December 31, 2010 increased 9.6% compared to the
same 2009 period. Approximately two-thirds of the growth was attributable to rate increases, while expansion of
our business in Texas, Colorado, Arizona and Connecticut contributed to the balance. Net written premiums for
the year ended December 31, 2009 increased 11.6% compared to the same 2008 period, with one-third of this
premium growth from rate increases, one-third from our expansion into Texas, Colorado, Arizona and
Connecticut, and the remaining one-third from expansion in our other states. We continue to aggressively address
our rate needs in this line of business, seeking higher rates in 2011. In addition, we intend to continue a
state-by-state deployment of our CustomFit homeowners product throughout 2011.

Business Insurance Segment Revenue

Our business insurance accounts are primarily small-to-medium sized exposures where we offer a broad
range of both property and liability coverages. New to us in 2010 are property and casualty coverages written
through RED, which acts as a managing general underwriter for a variety of property and casualty coverages in
the program and alternative risk markets, such as commercial auto, workers’ compensation, general liability and
property. The underwriting management agreement with RED went into effect during the fourth quarter 2009.
The insurance coverages written by our Pooled Companies through RED are subject to the Pooling Arrangement.

The following table sets forth a summary of written and earned premiums, net of reinsurance, by major
product line of business for our business insurance segment for the years ended December 31, 2010, 2009 and
2008. The one-time impacts of the 2010 and 2008 pooling changes have been excluded from 2010 and 2008 to
present net written premiums on a comparative basis (see Net Written Premiums Reconciliation Tables above).

Net written premiums for the business insurance segment for the year ended December 31, 2010 increased
15.5% compared to the same 2009 period, with business written through RED accounting for 19.1 points of this
premium growth or $83.2 million of new business written premium opportunities ($52.0 million of commercial
auto, $28.4 million of commercial multi-peril, $0.3 million of fire & allied lines and $2.5 million of other &
product liability), with our historic mainline business declining 3.6%. Net written premiums for the year ended
December 31, 2009 decreased 5.5% compared to the same 2008 period. Business insurance continues to be

55

impacted by rate competition, general economic conditions, and depressed premium bases, such as payrolls, sales
and number of vehicles, as well as ease of doing business issues. After strengthening our premium per exposure
on our renewal policies in the second half of 2009, our premium per exposure on policies other than policies
issued through RED decreased slightly in 2010. New business other than RED declined in 2010. We believe it
will be difficult to generate measurable premium growth in our current book of business, other than our RED
book of business, given the continued impact of the economy on premium bases. However, we are seeking to
balance our traditional underwriting discipline with new products and pricing tools that support the production of
profitable new business.

We continue to invest in products, processes and systems that we believe will increase our business
insurance writings. We have implemented a pricing process that we believe will help us price property, liability,
auto and workers’ compensation risks at appropriate levels. In addition, we have broadened our property,
liability, auto and workers’ compensation pricing ranges to improve our ability to recognize the spectrum of risks
within our markets.

We continue to enhance our insurance policy administration system to attempt to make it easier for our
agents to quote and submit business insurance policies to us. Our system now allows transactions to be processed
throughout the day using real-time and straight-through processing rather than in large batch cycles at night. We
have leveraged this functionality with bizXpressSM, our web-based quote system, to give agents the ability to
quote businessowners, commercial auto and workers’ compensation risks online. 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. The majority of all transactions in
business insurance utilize the straight-through processing technology. The use of this technology has resulted in
faster delivery of policies to our agents and their insureds for new business and endorsements. In the third quarter
2010, we expanded our electronic funds transfer billing capability, making it available to business insurance
policyholders.

We have also expanded the eligibility of our businessowners product to facilitate businesses with greater
liability exposures, such as artisan contractors, auto service garages, manufacturers and restaurants. While we
regularly insure these types of businesses through other insurance products, offering them in our businessowners
program leverages our bizXpress technology, simplifies agents’ rating and submission processes, and offers
broader base coverages for these types of risks. In 2010, we completed the implementation of our enhanced
businessowners product, which has been introduced into 28 states.

Loss and LAE

Losses and loss expenses for a calendar year represent the combined estimated ultimate liability for claims
occurring in the current calendar year along with any change in estimated ultimate liability for claims occurring
in prior years. The following table sets forth the provision for losses and loss expenses for those claims occurring
in the current and prior years, along with the GAAP loss and LAE ratio for the years ended December 31, 2010,

While emergence by accident year includes normal fluctuations due to the uncertainty associated with loss
reserve development and claim settlement, the favorable development in 2010 came primarily from accident year
2009. The more notable items contributing to the 2010 favorable development were:

•

•

•

ULAE was $12.7 million lower than anticipated in the reserves at December 31, 2009, with
approximately 78% being attributable to the 2009 accident year.

Favorable catastrophe loss development of $3.3 million was primarily associated with the 2009
accident year. This development occurred primarily within our homeowners and commercial multi-
peril lines of business.

Favorable development in the auto liability, homeowners and fire & allied lines accounts for the
majority of the development in the non-catastrophe reserves, with the balance spread across multiple
lines of business. Standard, nonstandard and commercial auto liability reserves developed favorably by
$10.7 million. Homeowners and fire & allied reserves developed lower than anticipated by $10.4
million and $9.0 million, respectively. The favorable development in these lines of business was driven
by emergence of lower than anticipated claim severity, as well as lower than anticipated claim
frequency for fire & allied lines. The favorable development was primarily associated with the 2009
and, to a lesser extent, 2008 accident years.

contributing to the 2009 favorable development were:

•

•

•

ULAE was $10.9 million lower than anticipated in the reserves at December 31, 2008, with

Favorable catastrophe loss development of $10.9 million was primarily associated with the 2008
accident year. This development occurred primarily within our homeowners, fire & allied and
commercial multi-peril lines of business.

Non-catastrophe reserves for the auto liability lines and other & product liability developed lower than
anticipated. Standard, nonstandard and commercial auto liability reserves developed $9.5 million lower
and other & product
than anticipated. This favorable
development, which was primarily associated with the 2008 accident year, was driven by lower than
anticipated tabular loss severity, as well as lower than anticipated loss frequency for other & product
liability.

The favorable development in 2008 came primarily from accident year 2007. The more notable items

contributing to the 2008 favorable development were:

•

•

•

ULAE was $13.7 million lower than anticipated in the reserves at December 31, 2007.

Favorable catastrophe loss development of $6.4 million was primarily associated with the 2007
accident year. This development occurred primarily within our homeowners, fire & allied and
commercial multi-peril lines of business.

Non-catastrophe homeowners reserves developed $4.9 million lower than anticipated. Current loss
projections using more mature claim data resulted in lower expected average claim severity than prior
projections, primarily from losses occurring in 2007.

See additional discussion regarding loss and loss expense reserves at the “Critical Accounting Policies –

Losses and Loss Expenses Payable” section included in this Item 7.

Catastrophe losses for 2010 totaled $99.0 million (7.9 loss ratio points) compared to $90.3 million (7.7 loss
ratio points) for 2009 and $156.1 million (13.9 loss ratio points) for 2008. During 2010, we were impacted by
losses from thirty of the thirty-three storms that were classified as numbered catastrophes by PCS as compared to
twenty-seven of the twenty-eight PCS classified storms in 2009. In 2008, we were impacted by losses from
thirty-five of the thirty-seven PCS classified storms, one of which was Hurricane Ike. The losses from these
catastrophes have had a significant impact on both our personal and business insurance property lines.

During 2010 and 2009, members of the State Auto Group maintained a property catastrophe net aggregate
excess of loss reinsurance agreement (the “CAT Aggregate Agreement”). See “Reinsurance Arrangements”
section included in this Item 7 for a further discussion of the CAT Aggregate Agreement. Of the thirty
catastrophes from which we experienced losses during 2010, nine met the minimum $5.0 million requirement;
however, in aggregate the total State Auto Group losses of $81.9 million related to the nine qualifying
catastrophes did not exceed the State Auto Group’s $90 million retention level. Six of the twenty-seven
catastrophes experienced during 2009 met the minimum $5.0 million requirement and in aggregate exceeded the
State Auto Group’s $80 million retention level. Our share of recoveries under the CAT Aggregate Agreement for
the year ended December 31, 2009 was $8.2 million, benefitting our loss ratio by 0.7 points.

In the personal insurance segment, the overall non-cat loss ratio for the year ended December 31, 2010
improved 3.8 points compared to the same 2009 period. The non-cat loss ratios for standard auto improved 2.6
points, and for homeowners improved 6.4 points, compared to the same 2009 period. The impact of rate increases
contributed significantly to the improvement in standard auto. Homeowners also improved relative to 2009,
benefitting from rate actions and implementation of mandatory wind and hail deductibles in many of our
operating states prone to non-cat weather related losses. In homeowners we continue to file rate increases in the
high single digit to low double digit range.

The personal insurance segment overall non-cat loss ratio was 4.1 points higher in 2009 than in 2008.
Standard auto’s non-cat
loss ratio increase was driven by an increase in frequency of physical damage,
comprehensive and collision coverage claims, while the nonstandard auto increase was caused by a rise in the
overall severity of claims. Previously, the intense price competition in the personal lines market had impeded our
ability to take appropriate rate increases. Price competition in the personal lines market became less intense,
which allowed us to implement rate increases, contributing some to our 2009 growth. The increase in the non-cat
homeowners loss ratio was due primarily to experiencing more large fire losses and settling one threatened class
action claim. Settlement of the one class action claim increased the 2009 non-cat homeowners loss ratio by 3.2
points.

In the business insurance segment, the overall non-cat loss ratio for the year ended December 31, 2010
increased 3.1 points compared to the same 2009 period. The commercial auto non-cat loss ratio increased 6.4
points, principally driven by an increase in the number of large losses which impacted both the current and prior
accident years. The other & product liability non-cat loss ratio increased by 18.1 points principally driven by an
increase in large losses from prior accident years. Intense competition in the business insurance segment
continues to impact our ability to implement price increases where needed.

The business insurance segment overall non-cat loss ratio for 2009 was comparable to 2008. However,
commercial auto and commercial multi-peril loss ratios decreased primarily due to a reduction in the number and
size of large losses when compared to 2008. The increase in the fire & allied lines loss ratio was the result of
more large fires in 2009. The increase in other & product liability was due primarily to an increase in the
estimate of internal claim handling expenses.

Initiatives implemented within our claims operations during 2009 and 2010 are contributing to the overall
decline in our loss ratio, particularly in the property lines of homeowners, fire and commercial multi-peril. Our
dependence on outside appraisers has declined by deploying over 70 in-house property adjusters working from
their homes. In addition, virtually all large property claims and a significant percentage of catastrophe claims are
now being handled in-house by State Auto adjusters. These changes improve service, reduce expenses, and allow
us to better manage indemnity payout – all of which improves loss ratio results.

The December 31, 2009 loss and loss expenses payable balance has been adjusted for comparative purposes to reflect the loss and loss
expenses payable ceded to the Mutual Pooled Companies on January 1, 2010 due to the 2010 pooling changes.

Loss and loss expenses payable increased $58.8 million since January 1, 2010, primarily due to an increase
in large losses for commercial auto and other & product liability, as well as growth. Loss and loss expenses
payable as of December 31, 2009 increased $49.4 million from December 31, 2008. The increase, driven by the
personal insurance segment, was primarily due to growth in exposures in our standard auto and homeowners
business. We conduct quarterly reviews of loss development reports and make judgments in determining the
reserves for ultimate losses and loss expenses payable. Several factors are considered by us when 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
changes, anticipated inflation, current business conditions, catastrophe developments, late reported claims, and
other reasonableness tests.

The risks and uncertainties inherent in our estimates include, but are not limited to, actual settlement
experience different from historical data, 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.

Acquisition and Operating Expenses

Our GAAP expense ratio was 33.8% in 2010 compared to 34.1% and 34.6% in 2009 and 2008, respectively.

In the second quarter of 2009, we initiated a plan to reorganize our field and claims operations. We
recognized restructuring costs totaling $2.3 million during the year ended December 31, 2010, which increased
our GAAP loss and LAE and expense ratios by 0.1 points each. We recognized restructuring costs totaling $4.8
million during the year ended December 31, 2009, which increased our GAAP loss and LAE and expense ratios
by 0.2 points each. See Note 9, “Restructuring Costs” to our consolidated financial statements included in Item 8
of this Form 10-K.

Investment Operations Segment

Our investment portfolio and the investment portfolios of other members of the State Auto Group are
managed by our subsidiary, Stateco. Stateco utilizes its own personnel to invest in fixed maturities and large-cap
equities and outside investment managers to invest in small-cap equities and international funds. The Investment
Committee (the “Committee”) of the Board of Directors establishes the investment policies to be followed by
Stateco. Our primary investment objectives are to generate income, preserve capital and maintain adequate
liquidity for the payment of claims and expenses. Our current investment strategy does not rely on the use of
derivative financial instruments.

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. 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, 2010, there were no fixed maturity
investments rated below investment grade in our available-for-sale investment portfolio. At December 31, 2010
and 2009, our only investments in mortgage backed securities were in federal agency pools (Fannie Mae and
Freddie Mac) and government guaranteed pools (Ginnie Mae).

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.

Our externally managed equity portfolios invest in U.S. small-cap equities and international funds. These
managers are permitted to manage the portfolios according to their own respective portfolio objectives. In
selecting our outside investment 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.

Diversifying our portfolio into small-cap equities and international equity funds was designed to achieve a
greater total return with reduced volatility. We believe that in most market cycles, diversification of the portfolio
will be beneficial to us, and we plan to continue to maintain a diversified portfolio.

At December 31, 2010, 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 income (loss) and as such are not included in the determination of net income (loss).

At December 31, 2010, our equity portfolio consisted of approximately 65 different large-cap stocks and 75
small-cap stocks. The largest single position was 2.7% of the equity portfolio based on fair value, and the top ten
positions accounted for 20.8% of the equity portfolio. At December 31, 2009, our equity portfolio consisted of
approximately 67 different large-cap stocks and 76 small-cap stocks. The largest single position was 2.9% of the
equity portfolio based on fair value and the top ten positions account for 22.6% of the equity portfolio. Since our
equity portfolio consists primarily of large-cap value-oriented stocks, with a small allocation to small-cap
equities, 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.

Market Risk

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 5.01 and 4.99 as of December 31, 2010 and 2009, respectively. The following table sets forth our
interest rate risk and the effects of a parallel change in interest rates on the fair value of the available-for-sale
fixed maturity portfolio at December 31, 2010:

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 approximately 91.8% of
the bonds we own are rated AA or better. 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 mortgage backed securities in our fixed maturity portfolio which may be labeled sub-prime
mortgage backed securities. We invest only in conventional mortgage backed securities issued by a federal
agency or that are U.S. Government guaranteed. Specifically, approximately $363.6 million or 16.3% of our
available-for-sale investment portfolio as of December 31, 2010, were in either Ginnie Mae pools, which are
guaranteed by the full faith and credit of the U.S. Government, or Fannie Mae or Freddie Mac pools. In 2008,
both Fannie Mae and Freddie Mac received additional U.S. Government backing when they were placed into
conservatorship.

Our fixed maturity investment portfolio at December 31, 2010 included obligations of states and political
subdivisions with a total carrying value of $933.6 million. $441.2 million of these securities, or 47.3% of our
municipal securities portfolio (“Muni Portfolio”), were enhanced by third party monoline insurers (a “Credit
Enhancement”) for the payment of principal and interest in the event of an issuer default. A Credit Enhancement
is not a primary consideration to us when purchasing a municipal security, as we consider the underlying credit
quality of the security as the primary rating factor in our evaluation process. Of the total $933.6 million of
municipal securities in our investment portfolio at December 31, 2010, 90.9% 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. In addition, as of
December 31, 2010, we had no direct investment in any guarantor including any bond insurer.

We believe our Muni Portfolio is well diversified by issuer and state. We have 12.6% invested in securities
which have been either pre-refunded or escrowed to maturity bonds. Within the non pre-refunded and escrowed
to maturity portfolio, no single issuer comprises more than 5% of the portfolio and no more than 10% of the
portfolio is concentrated in any one state. We believe our Muni Portfolio is invested within the strongest sectors
of the municipal bond market. 34.6% of our municipal bonds are general obligation bonds or other tax-backed
bonds. The majority of the remaining Muni Portfolio consists of revenue bonds. Our credit research is an
important part of our investment management process, and we continually monitor all holdings for any signs of
deterioration. We believe that our municipal holdings will maintain their high credit quality and that the issuers
will be able to make all principal and interest payments as they come due.

During 2010, the level of call activity in our fixed maturity portfolio increased when compared to 2009 and
2008. The proceeds from the call, maturity or sale of securities within our Muni Portfolio, which are long
duration, tax exempt securities, have been reinvested into shorter duration, taxable fixed income securities with
lower rates of return.

As of December 31, 2010, our large-cap equity portfolio had a beta of 0.95 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 following table sets forth what changes might occur in the value of the large-cap equity
portfolio given a change in the S&P 500 Index at December 31, 2010:

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 large-cap 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.

At December 31, 2010, we have two international funds, Fund 1 and Fund 2, which are included in other
invested assets available-for-sale. Fund 1 and Fund 2 had betas of 0.71 and 0.90, respectively, using the MSCI
EAFE Index as a benchmark. Beta estimates the degree the portfolio’s price will fluctuate based on a given
movement in the index. The following tables set forth what changes might occur in the values of Funds 1 and 2
given a change in the MSCI EAFE Index at December 31, 2010:

response to these changes. As a result, the actual impact of a change in international equity market prices and the
resulting international equity values may differ significantly from what is shown in the tables above.

Investment Operations Revenue

Net investment income for 2010 was $80.8 million compared to $82.1 million and $87.4 million in 2009
and 2008, respectively. Average invested assets were $2,235.7 million at December 31, 2010, an increase from
$2,117.0 million and $2,127.6 million at December 31, 2009 and 2008, respectively. Our investment yield
declined to 3.6% in 2010 from 3.9% and 4.1% in 2009 and 2008, respectively. These changes were primarily due
to the following factors.

•

•

•

The amount of interest earned on our fixed maturity securities declined due to a shift in this portfolio to
holding higher levels of taxable bonds with shorter durations and lower rates of return and fewer long
duration tax exempt bonds earning higher rates of return. Also contributing to the decrease in net
investment income was an increase in the call activity on our higher yielding bonds when compared to
2009 and 2008.

The amortized cost value of our Treasury Inflation-Protected Securities (“TIPS”) increased to $187.6
million for the year ended December 31, 2010, as compared to $137.0 million and $77.9 million for the
same 2009 and 2008 periods, respectively. The income earned on our TIPS securities, which is
dependent on changes in the CPI Index, increased by $2.7 million in 2010 when compared to the same
2009 period, and decreased by $0.5 million in 2009 when compared to the same 2008 period.

To offset the decline in interest earned on our fixed maturity securities and to improve yield and cash
flows, in 2010 we began to hold more high dividend paying equities when compared to 2009. In 2009,
we held fewer large-cap dividend paying stocks than in 2008, and dividend payouts were reduced on
certain equity holdings.

Equity sales were executed for various reasons in 2010, 2009 and 2008, including the achievement of our
price target. We recognized realized losses on the sale of certain equity securities during 2010, 2009 and 2008 in
response to a continuing decline in stock price and negative outlook announcements or changes in business
conditions, which in our opinion diminished the future business prospects on these securities. During 2009, we

69

State Auto 10-K High Res for Annual Report.pdf   71

3/9/11   9:32 PM

sold fixed maturities to shorten the duration of our investment portfolio, which resulted in realized gains on
certain municipal bonds that were replaced with taxable bonds.

When a fixed maturity security has been determined to have an other-than-temporary decline in fair value,
the impairment charge is separated into an amount representing the credit loss, which is recognized in earnings,
and the amount related to non-credit factors, which is recognized in accumulated other comprehensive income
(loss). See “Critical Accounting Policies – Investments” included in this Item 7 for OTTI impairment indicators.
Future increases or decreases in fair value, if not other-than-temporary, are included in accumulated other
comprehensive income (loss). We did not recognize OTTI on our fixed maturity portfolio during 2010 or 2009,
and recognized less than $0.1 million in 2008.

When an equity security or other invested asset 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. See “Critical Accounting Policies –
Investments” included in this Item 7 for OTTI impairment indicators. This results in a charge to earnings as a
realized loss, which is not reversed for subsequent recoveries in fair value. Future increases or decreases in fair
value, if not other-than-temporary, are included in accumulated other comprehensive income (loss).

Gross Unrealized Investment Gains and Losses

Based upon our review of our investment portfolio at December 31, 2010, we determined that there were no
individual investments with an unrealized holding loss that had a fair value significantly below cost continually
for more than one year. The following table sets forth detailed information on our available-for-sale investment
portfolio by lot at fair value for our gross unrealized holding gains (losses) at December 31, 2010:

Fair Value Measurements

We primarily use one independent nationally recognized pricing service in developing fair value estimates.
We obtain one price per security, and our processes and control procedures are designed to ensure the value is
accurately recorded on an unadjusted basis. Through discussions with the pricing service, we gain an
understanding of the methodologies used to price the different types of securities, that the data and the valuation

71

State Auto 10-K High Res for Annual Report.pdf   73

3/9/11   9:32 PM

methods utilized are appropriate and consistently applied, and that
the assumptions are reasonable and
representative of fair value. To validate the reasonableness of the valuations obtained from the pricing service,
we compare to other fair value pricing information gathered from other independent pricing sources. See Note 3,
“Fair Value of Financial Instruments” to our consolidated financial statements included in Item 8 of this Form
10-K for a presentation of our available-for-sale investments within the fair value hierarchy at December 31,
2010.

As of December 31, 2010, Level 3 assets as a percentage of total assets were 0.1%, which we have

determined to be insignificant.

Other Items

Income Taxes

For the year ended December 31, 2010, federal income tax expense was less than $0.1 million compared to
a tax (benefit) of $(23.0) million and $(44.0) million for the same 2009 and 2008 periods, respectively. The
effective tax rate for 2010 of 0.1% differs from the statutory rate of 35% principally because of tax exempt
investment income. In addition, in 2010 we incurred a one-time tax charge of $4.5 million related to the
enactment of the Patient Protection and Affordable Care Act. This legislation eliminated the tax benefit
associated with Medicare Part D subsidies we receive for providing qualifying prescription drug coverage to
retirees.

See Note 8, “Federal Income Taxes” to our consolidated financial statements included in Item 8 of this
Form 10-K for a reconciliation between our actual federal income tax expense (benefit) and the amount
computed at the indicated statutory rate for the years ended December 31, 2010, 2009 and 2008.

LIQUIDITY AND CAPITAL RESOURCES

General

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

We maintain a portion of our investment portfolio in relatively short-term and highly liquid investments to
ensure the immediate availability of funds to pay claims and expenses. At December 31, 2010 and 2009, we had
$88.3 million and $90.3 million, respectively, in cash and cash equivalents, and $2,236.6 million and $2,108.2
million, respectively, of total available-for-sale investments. Included in our fixed maturities available-for-sale
are $72.2 million and $56.9 million, respectively, of securities on deposit with insurance regulators as required
by law at December 31, 2010 and 2009. 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 because 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.

72

State Auto 10-K High Res for Annual Report.pdf   74

3/9/11   9:32 PM

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 premiums 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 the other expenses line item in the accompanying consolidated 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 position. For a discussion of our reinsurance arrangements, see
“Reinsurance Arrangements” included in this Item 7.

We generally manage our cash flows through current operational activity and maturing investments, without
a need to liquidate any of our other investments. However, should our written premiums decline or paid losses
increase significantly, or a combination thereof, our cash flows from operations could be impacted requiring us to
liquidate investments at losses. This action was not necessary in 2010, 2009 or 2008 despite the increased level
of catastrophe losses.

Net cash provided by operating activities was $131.4 million, $110.5 million and $183.5 million for 2010,
2009 and 2008, respectively. Net cash from operations will vary from period to period if there are significant
changes in underwriting results, primarily a combination of the level of premiums written and loss and loss
expenses paid, changes in cash flows from investment income or federal income tax activity. Included in 2010
and 2008 operational cash activity are cash inflows of $3.7 million and $92.0 million, respectively, due to
pooling changes. 2010 and 2008 reflect cash outflows of $6.2 million and $18.2 million, respectively, related to
federal income tax activity, while 2009 recorded tax receipts of $38.1 million. While premium receipt levels
between years increased, losses paid on catastrophes fluctuated significantly between years, in particular with
respect to 2009. Approximately one-third of the catastrophe losses in 2008, primarily Hurricane Ike, occurred in
the last of half of the year, where settlement on much of this claim activity with State Auto Mutual did not occur
until 2009.

During 2010, 2009 and 2008, as permitted by regulations of the Internal Revenue Service, we made cash
contributions of $13.0 million, $15.0 million and $12.0 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 plan is generally not determined until the second
quarter with respect to the contribution year, though we currently expect to make a minimum cash contribution to
our defined benefit pension plan up to $15.0 million during 2011. For a further discussion regarding our defined
benefit pension plan, see “Critical Accounting Policies – Pension and Postretirement Benefit Obligations”
included in this Item 7.

Net cash used in investing activities was $112.6 million, $150.2 million and $51.5 million for 2010, 2009

and 2008, respectively. The following contributed to the fluctuations between those years:

•

•

In 2010, we had a cash outflow of $7.5 million related to the sale of SA National on December 31,
2010. This amount approximated SA National’s cash position on that date. We received net cash
inflows of $13.2 million in early January 2011 related to the sale of SA National.

At the beginning of 2009, we held higher levels of cash as a result of our conservative approach to
investing as markets weakened in the last half of 2008 and because of our need to pay claims
associated with the higher level of catastrophes occurring during the second half of 2008. During 2009,
as markets improved and claim activity returned to more normal levels, we began reinvesting as
opportunities arose, including loaning State Auto Mutual $70.0 million.

Our financing activities for 2010, 2009 and 2008 produced net cash outflows of $20.8 million, $20.5

million, and $52.4 million, respectively. The following contributed to the fluctuations between those years:

•

•

Cash used to repurchase common shares under our stock repurchase program was $33.2 million in
2008. No shares were repurchased 2009. This repurchase program ended in 2009. See “Other Capital
Transactions” below.

Dividends paid to shareholders totaled $24.0 million, $23.8 million and $23.9 million for 2010, 2009
and 2008, respectively. Dividends paid per common share were $0.60 in 2010, 2009 and 2008.

Other Capital Transactions

In August 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 the Company’s outstanding shares. This
program ended in December 2009. State Auto Financial repurchased shares from State Auto Mutual in amounts
that were proportional to its ownership percentages of State Auto Mutual, which was approximately 64%, and
other shareholders. There were no shares repurchased for the year ended December 31, 2009. For the year ended
December 31, 2008 a total of 1,214,586 of common shares were purchased under this program at an average
repurchase price of $27.25 per share for a total of $33.2 million. For the lifetime of the program, a total of
2,028,116 common shares were purchased at an average purchase price of $27.26 per share for a total of $55.3
million.

On November 5, 2010, the Board of Directors of State Auto Financial declared a cash dividend of $0.15 per
share. The dividend was payable on December 31, 2010, to shareholders of record on December 13, 2010. On
March 4, 2011, the Board of Directors of State Auto Financial declared a cash dividend of $0.15 per share. The
dividend is payable on March 31, 2011, to shareholders of record on March 14, 2011. This is the 79th 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.

During 2010, SA National and Stateco paid dividends of $56.4 million and $5.0 million, respectively, to
State Auto Financial, and State Auto Financial made a capital contribution of $21.0 million to State Auto P&C.
The SA National dividend was considered extraordinary for regulatory purposes.

Borrowing Arrangements

Credit Agreement

State Auto Financial has a credit facility (the “Credit Facility”) with a syndicate of financial institutions.
The Credit Facility provides for a $100.0 million unsecured revolving credit facility maturing in July 2012. The
Credit Facility is available for general corporate purposes. The Credit Facility provides for interest-only
payments during its term, with principal and interest due in full at maturity. Interest is based on LIBOR or a base

74

State Auto 10-K High Res for Annual Report.pdf   76

3/9/11   9:32 PM

rate plus a calculated margin amount. The Credit Facility includes certain covenants, including financial
covenants that require State Auto Financial to maintain a minimum net worth and not exceed a certain debt to
capitalization ratio. As of December 31, 2010, State Auto Financial had not made any borrowings and was in
compliance with all covenants related to the Credit Facility.

Senior Notes

State Auto Financial has outstanding $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 State Auto Financial’s
subsidiaries’ existing and future indebtedness.

Subordinated Debentures

State Auto Financial’s Delaware business trust subsidiary (the “Capital Trust”) has outstanding $15.0
million liquidation amount of capital securities, due 2033. In connection with the Capital Trust’s issuance of the
capital securities and the related purchase by State Auto Financial of all of the Capital Trust’s common securities
(liquidation amount of $0.5 million), State Auto Financial has issued to the Capital Trust $15.5 million aggregate
principal amount of unsecured Floating Rate Junior Subordinated Debt Securities due 2033 (the “Subordinated
Debentures”). The sole assets of the Capital Trust are the Subordinated Debentures and any interest accrued
thereon. Interest on the Capital Trust’s capital and common securities is payable quarterly at a rate equal to the
three-month LIBOR rate plus 4.20%, adjusted quarterly. The applicable interest rates for December 31, 2010 and
2009 were 4.50% and 4.46%, respectively.

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, 2010, we had $15.5 million notes
payable with variable interest and $101.3 million notes payable with interest fixed at 6.25%, which equated to
approximately 13.3% variable interest debt and 86.7% 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. See our contractual obligations
table included in “Contractual Obligations” included in this Item 7.

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

75

State Auto 10-K High Res for Annual Report.pdf   77

3/9/11   9:32 PM

reduce net liability on individual risks or for individual loss occurrences, including catastrophic losses. Although
reinsurance does not legally discharge the individual members of the State Auto Group from primary liability for
the full amount of limits applicable under their policies, it does make the assuming reinsurer liable to the extent
of the reinsurance ceded.

Each member of the State Auto Group is party to working reinsurance treaties for casualty, workers’
compensation and property lines with several reinsurers arranged through a reinsurance intermediary. These
agreements are described in more detail below. We have also secured other reinsurance to limit the net cost of
large loss events for certain types of coverage written in certain companies, including reinsurance covering
umbrella liability losses up to a limit of $10.0 million with a maximum of $0.6 million retention. The State Auto
Group also makes use of facultative reinsurance for unique risk situations. The State Auto Group also
participates in state insurance pools and associations. In general, these pools and associations are state sponsored
and/or operated, impose mandatory participation by insurers doing business in that state, and offer coverage for
hard-to-place risks at premium rates established by the state sponsor or operator, thereby transferring risk of loss
to the participating insurers in exchange for premiums which may not be commensurate with the risk assumed.

The casualty excess of loss reinsurance agreement provides 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 $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 workers’ compensation excess of loss reinsurance agreement provides 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 agreement may be
submitted to the casualty excess of loss agreement, 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 described above, each company in the State Auto
Group is party to an agreement which provides an additional layer of 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” limitation of $10.0 million. This limitation means that losses associated with each worker may
contribute no more than $10.0 million to covered loss under this agreement. The rates for this reinsurance are
negotiated annually.

The property per risk excess of loss reinsurance agreement provides that each company in the State Auto
Group is responsible for the first $3.0 million of each covered loss, as well as an additional $2.0 million in
aggregate retention per treaty year. 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.

Members of the State Auto Group maintain a property catastrophe excess of loss reinsurance agreement
covering catastrophe related 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 $110.0 million of covered loss, each occurrence. The reinsurers are responsible for 95% of the excess over
$55.0 million up to $165.0 million of covered losses, each occurrence. Our companies are responsible for losses
above $165.0 million. Prior to August 1, 2010, this reinsurance provided coverage up to $155.0 million of
covered losses, each occurrence. The rates for this reinsurance are negotiated annually.

3/9/11   9:32 PM

During 2010, members of the State Auto Group also maintained a CAT Aggregate Agreement. The
agreement provided reinsurance coverage on an annual basis for certain qualifying catastrophic events, including
certain events falling below the $55.0 million retention under the property catastrophe excess of loss reinsurance
agreement discussed in the preceding paragraph. Events covered by the Catastrophe Aggregate Agreement would
need to be PCS numbered catastrophes, excluding earthquakes and named storms such as hurricanes and tropical
storms. Individual occurrences were capped at $55.0 million and were subject to a $5.0 million franchise
deductible, meaning occurrences producing losses totaling less than $5.0 million were excluded. Subject to these
limitations, qualifying losses from individual occurrences were then aggregated over the course of the
reinsurance term, January 1, 2010 through December 31, 2010. On an aggregate basis the members of the State
Auto Group combined retained the first $90.0 million of covered loss, with a 25% co-participation on the next
$30.0 million of covered loss. The reinsurer was responsible for 75% of the excess over $90.0 million up to
$120.0 million of covered loss on an aggregate basis. This agreement was not renewed for 2011.

Concurrent with our sale of SA National, SA National’s participation in the Pooling Arrangement was
terminated, and we entered into a loss portfolio transfer and a 100% quota share reinsurance agreements on
December 31, 2010 to assume liability for the pre- and post-closing book of business of SA National, including
providing policy and claims service to SA National policyholders, until policies are renewed with the third party
purchaser on such purchaser’s systems during a transition period of up to six months following effective date of
sale. This assumed business by us is subject to the Pooling Arrangement.

With the introduction of the Rockhill Insurers into our Pooling Arrangement beginning January 1, 2011, we
maintain certain reinsurance agreements to provide protection tailored to the specialized risks written through our
Rockhill specialty insurance unit.

For certain casualty lines, we have a consolidated casualty treaty whereby we retain the first $0.5 million of
covered loss and the reinsurers are responsible for 95% of the excess over $0.5 million up to $6.0 million per
risk. On certain property lines, we maintain a quota share agreement whereby we retain 25% of each loss, per
occurrence on all property risks, up to a $12.5 million and the reinsurers are responsible for 75% of each loss up
to $12.5 million.

We maintain a property surplus share agreement for wind only insurance products. This agreement provides
for a proportional share of losses on all coastal wind policies written with limits greater than $5.0 million and up
to $10.0 million of covered loss and all non coastal wind policies written with limits greater than $10.0 million
and up to $15.0 million of covered loss. The reinsurers’ limit cannot exceed more than $5.0 million on any one
risk.

Our Rockhill specialty insurance unit maintains a property catastrophe excess of loss reinsurance agreement
covering catastrophe related events affecting at least two risks. Additionally, we retain the first $5.0 million of
catastrophe loss, each occurrence, and the reinsurers are responsible for 100% of the excess over $5.0 million up
to $80.0 million of covered loss, each occurrence.

(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 “Critical Accounting Policies – Losses and Loss Expenses Payable” included in
this Item 7. These patterns were applied to the December 31, 2010, 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,
2010 of 0.3028% plus 4.20%, or 4.5028%.
These amounts are estimates of ERISA minimum funding levels based on adjustments to prior year assumptions for our defined
benefit pension plan and do not represent an estimate of our expected contributions. Funding levels generally are not determined
until later in the year with respect to the contribution year. See Note 10, “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, 2010, 2009 and 2008, each of our insurance subsidiaries was in compliance with statutory

requirements relating to capital adequacy.

The NAIC utilizes a collection of analytical tools designed to assist state insurance departments with an
integrated approach to screening and analyzing the financial condition of insurance companies operating in their
respective states. One such set of analytical tools is 12 key financial ratios that are known in the insurance

78

State Auto 10-K High Res for Annual Report.pdf   80

3/9/11   9:32 PM

industry as the “IRIS” ratios. 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 premiums written to surplus or 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 leverage ratios increased in 2010. While premiums grew 9.3%, surplus declined 1.7%. Of the total
$13.7 million decline in surplus, $40.8 million was related to the dividends and sale of SA National. At
December 31, 2009, SA National had $61.8 million in surplus, and of the dividends paid to STFC during 2010,
$21.0 million was contributed from STFC to State Auto P&C. Offsetting the SA National decline was the 2010
unrealized holding gains on investments and net income on the remaining insurance subsidiaries.

The following table sets forth the statutory leverage ratios for our insurance subsidiaries at December 31,

Table excludes the one-time impact on net written premiums of $1.4 million and $53.6 million that occurred in conjunction
with the 2010 and 2008 pooling changes, respectively.

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, $78.3 million is available in 2011 for payment as a dividend from our insurance
subsidiaries to State Auto Financial, without prior approval from our respective domiciliary state insurance
departments. In 2010, 2009 and 2008, State Auto Financial received $56.4 million, $11.5 million and $39.0
million, respectively in dividends from its insurance subsidiaries. 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 requirements, which 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, 2010, the ratio of
total adjusted statutory capital to authorized control level of State Auto Financial’s insurance subsidiaries ranged
from 671% to 994%.

Standard & Poor’s

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 has 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.

Our ratings are influenced by many factors including operating and financial performance, asset quality,
liquidity, financial leverage, exposure to catastrophe risks and operating leverage. Presently, our A.M. Best
ratings are assigned negative outlooks, whereas, Moody’s and Standard & Poor’s ratings are assigned stable
outlooks.

In May 2010, Standard & Poor’s lowered our credit rating from BBB to BBB- and our financial strength
rating from A to A- primarily because of our recent operating and financial results in comparison to our historical
results, among other factors.

OTHER

Impact of Inflation

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. Even when general
inflation, as measured by the Consumer Price Index, is relatively modest, as has been the case over the last
several years, price inflation on the goods and services purchased by insurance companies in settling claims can
steadily increase. For example, medical care costs have risen at a higher rate than general inflation over the last
few years. Costs for building materials typically rise dramatically following widespread natural catastrophes,
such as the industry experienced in 2008 with Hurricane Ike and 2006 with Hurricane Katrina. We continue to
adjust our pricing projections to reflect current and anticipated changes in costs 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 final 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.

New Accounting Standards

Adoption of Recent Accounting Pronouncements

Amendments to Accounting for Variable Interest Entities

In June 2009, the FASB issued revised guidance on the accounting for variable interest entities. The revised
guidance, which was issued as Statement of Financial Accounting Standards (“SFAS”) No. 167, Amendments to
FASB Interpretation No. 46(R), is included in the Consolidation Topic of the FASB Accounting Standards
Codification (“ASC”). The revised guidance eliminates the concept of a qualifying special-purpose entity and
replaces the quantitative-based risks and rewards calculation of the previous guidance for determining which
company, if any, has a controlling financial interest in a variable interest entity. The revised guidance requires an
analysis of whether a company has: (1) the power to direct the activities of a variable interest entity that most
significantly impact the entity’s economic performance and (2) the obligation to absorb the losses that could
potentially be significant to the entity or the right to receive benefits from the entity that could potentially be
significant to the entity. An entity is required to be re-evaluated as a variable interest entity when the holders of
the equity investment at risk, as a group, lose the power from voting rights or similar rights to direct the activities
that most significantly impact the entity’s economic performance. Additional disclosures are required about a
company’s involvement in variable interest entities and an ongoing assessment of whether a company is the
primary beneficiary. The adoption of the new guidance effective January 1, 2010 had no effect on our
consolidated financial statements.

Improving Disclosures about Fair Value Measurements

In January 2010,

the FASB issued guidance to improve the disclosures related to fair value
measurements. The new guidance requires expanded fair value disclosures, including the reasons for significant
transfers between Level 1 and Level 2 and the amount of significant transfers into each level disclosed separately
from transfers out of each level. For Level 3 fair value measurements, information in the reconciliation of
recurring Level 3 measurements about purchases, sales, issuances and settlements shall be presented separately
on a gross basis, rather than as one net number. In addition, clarification is provided about existing disclosure
requirements, such as presenting fair value measurement disclosures for each class of assets and liabilities that
are determined based on their nature and risk characteristics and their placement in the fair value hierarchy (that
is, Level 1, 2, or 3), as opposed to each major category of assets and liabilities, as required in the previous
guidance. Disclosures about the valuation techniques and inputs used to measure fair value for both recurring and
nonrecurring fair value measurements are required for fair value measurement that fall in either Level 2 or
Level 3. We adopted this new guidance effective January 1, 2010, except for the gross presentation of purchases,
sales, issuances and settlements in the Level 3 reconciliation, which is effective for annual and interim reporting
periods beginning after December 15, 2010. The disclosures required by this new guidance are provided in
Note 3 of the accompanying consolidated financial statements.

Pending Adoption of Accounting Pronouncements

Accounting for Costs Associated with Acquiring or Renewing Insurance Contracts

In October 2010, the FASB issued updated guidance to address diversity in practice for the accounting of
costs associated with acquiring or renewing insurance contracts. This guidance modifies the definition of
acquisition costs to specify that a cost be directly related to the successful acquisition of a new or renewal
insurance contract in order to be deferred. The new guidance is effective on a prospective basis for fiscal years
beginning after December 15, 2011, with early adoption permitted. Retrospective application is also permitted,
but not required. We are still assessing the impact the provisions of the new guidance will have on our
consolidated financial statements.

Item 8. Financial Statements and Supplementary Data

Our consolidated financial statements, including the notes thereto, and the reports of Ernst & Young LLP on

our consolidated financial statements and our internal controls over financial reporting are as follows:

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, 2010 and 2009, and the related consolidated statements of income, stockholders’
equity, and cash flows for each of the three years in the period ended December 31, 2010. 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, 2010 and
2009, and the consolidated results of their operations and their cash flows for each of the three years in the period
ended December 31, 2010, 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 other-than-temporary impairments of investments in fixed maturity securities in 2009.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board
(United States), State Auto Financial Corporation and subsidiaries’ internal control over financial reporting as of
December 31, 2010, based on criteria established in Internal Control—Integrated Framework issued by the

Report of Independent Registered Public Accounting Firm on Internal Control over Financial Reporting

The Board of Directors and Stockholders of
State Auto Financial Corporation

We have audited State Auto Financial Corporation and subsidiaries’ internal control over financial reporting
as of December 31, 2010, 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 and subsidiaries maintained, in all material respects,

effective internal control over financial reporting as of December 31, 2010, 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 and subsidiaries as of
December 31, 2010 and 2009, and the related consolidated statements of income, stockholders’ equity, and cash
flows for each of the three years in the period ended December 31, 2010, and our report dated March 8, 2011,
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”), an

Ohio corporation, and the following wholly owned subsidiaries of State Auto Financial:

•

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

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

The consolidated financial statements also include the operations and financial position of 518 Property
Management and Leasing, LLC (“518 PML”), an Ohio limited liability company whose members are State Auto
P&C and Stateco. The consolidated financial statements also include the operations of State Auto National
Insurance Company (“SA National”), an Ohio corporation and a wholly owned subsidiary of State Auto
Financial through December 31, 2010, the date SA National was sold to a third party.

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

On December 31, 2010, State Auto Financial sold SA National to a third party for $14.0 million plus a
contingent earn-out of up to $2.0 million. In 2010, SA National wrote approximately $37.0 million in direct
written premium, with 80% (or approximately $30.0 million) retained by the Company under the Pooling
Arrangement (see Note 6). Included in net realized gain (loss) on investments for the year ended December 31,
2010 was a $3.9 million net gain on the sale of SA National. Included in accrued investment income and other
assets as of December 31, 2010 was $15.0 million in estimated sale proceeds receivable.

b. Description of Business

The Company markets a broad line of property and casualty insurance products in all 50 states and the
District of Columbia exclusively through independent insurance agencies, which include retail agents and
wholesale brokers. The Company’s principal lines of insurance include personal and commercial automobile,
homeowners, commercial multi-peril, workers’ compensation, general liability and fire insurance. 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 underwriting activity
and geographic distribution of State Auto Mutual and its affiliates is generally the same as the underwriting
activity and geographic distribution of the Company.

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

Notes to Consolidated Financial Statements, Continued

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

under management agreements for all of its insurance and non-insurance affiliates.

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

518 PML owns and leases property to the Company’s affiliates.

c. Basis of Presentation

The consolidated financial statements have been prepared in conformity with U.S. generally accepted
accounting principles (“GAAP”), which vary in certain respects from statutory accounting practices (“SAP”)
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 and the realizability of deferred tax assets. In connection with
the determination of losses and loss expenses payable, management uses historical data, current business
conditions and assumptions about future conditions to formulate estimates of the ultimate cost to settle claims.
Deferred tax assets are evaluated periodically by management to determine if they are realizable, requiring
management to make certain judgments and assumptions. In evaluating the ability to recover deferred tax assets,
management considers all available evidence, including loss carryback potential, past operating results, existence
of cumulative losses in the most recent years, projected performance of the business, future taxable income,
including the ability to generate capital gains, and prudent and feasible tax planning strategies. If, based on
available information, it is more likely than not that the deferred income tax asset will not be realized, then a
valuation allowance must be established with a corresponding charge to net
income and/or accumulated
comprehensive loss. These estimates by their nature are subject 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 or it is
determined the deferred tax asset is not realizable.

d. Investments

Investments in fixed maturities, equity securities and certain other invested assets are classified as
available-for-sale and are carried at fair value. The unrealized holding gains and losses, net of applicable deferred
income taxes, are shown as a separate component of stockholders’ equity as a part of accumulated other
comprehensive loss and, as such, are not included in the determination of net income (loss). 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, an assessment
judgment
regarding the evidence known. Such judgments could change in the future as more information becomes known,

that requires significant management

STATE AUTO FINANCIAL CORPORATION AND SUBSIDIARIES

Notes to Consolidated Financial Statements, Continued

which could negatively impact the amounts reported. Among the factors that management considers for fixed
maturity securities are the financial condition of the issuer including receipt of scheduled principal and interest
cash flows, and intent to sell including if it is more likely than not that the Company will be required to sell the
investments before recovery. When a fixed maturity has been determined to have an other-than-temporary
impairment, the impairment charge is separated into an amount representing the credit loss, which is recognized
in earnings as a realized loss, and the amount related to non-credit factors, which is recognized in accumulated
other comprehensive loss. Future increases or decreases in fair value, if not other-than-temporary, are included in
accumulated other comprehensive loss.

Among the factors that management considers for equity securities and other invested assets are the length
of time and/or the significance of decline below cost, the Company’s ability and intent to hold these securities
through their recovery periods, the current financial condition of the issuer and its future business prospects, and
the ability of the market value to recover to cost in the near term. When an equity security or other invested asset
has been determined to have a decline in fair value that is other-than-temporary, the cost basis of the security is
adjusted to fair value. This results in a charge to earnings as a realized loss, which is not reversed for subsequent
recoveries in fair value. Future increases or decreases in fair value, if not other-than-temporary, are included in
accumulated other comprehensive loss.

e. Cash Equivalents

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

equivalents. The carrying amounts reported approximate their fair value.

f. 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. Future changes in estimates, the most significant of which is
expected losses and loss adjustment expenses, that indicate a reduction in expected future profitability may result
in unrecoverable deferred acquisition costs. The Company has not recorded any significant changes in estimates
for the years ended December 31, 2010, 2009 and 2008, respectively.

Notes to Consolidated Financial Statements, Continued

g. Federal Income Taxes

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

The Company recognizes deferred income tax assets and liabilities for the expected future tax effects
attributable to temporary differences between the financial statement and tax return bases of assets and liabilities,
based on enacted tax rates and other provisions of the tax law. The effect of a change in tax laws or rates on
deferred tax assets and liabilities is recognized in income in the period in which such change is enacted. Deferred
tax assets and liabilities include provisions for unrealized investment gains and losses as well as the net funded
status of pension and other postretirement benefit obligations with the changes for each period included in the
respective components of accumulated other comprehensive loss in stockholders’ equity. Deferred tax assets are
reduced by a valuation allowance if it is more likely than not that all or some portion of the deferred tax assets
will not be realized.

Interest and penalties related to uncertain tax positions are recorded in the balance sheet as other liabilities,

and recognized in the income statement as other expenses.

h. Losses and Loss Expenses Payable

Losses and loss expenses payable are based on formula and case-basis estimates for reported claims and on
estimates, based on experience and perceived trends, for unreported claims and loss expenses. The liability for
unpaid losses and loss expenses, net of estimated salvage and subrogation recoverable of $28.3 million and $33.3
million at December 31, 2010 and 2009, respectively, has been established to cover the estimated ultimate cost to
settle insured losses. The amounts are 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 (loss) 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. New Accounting Standards

Adoption of Recent Accounting Pronouncements

Amendments to Accounting for Variable Interest Entities

In June 2009,

the Financial Accounting Standards Board (“FASB”) issued revised guidance on the
accounting for variable interest entities. The revised guidance, which was issued as Statement of Financial
Accounting Standards (“SFAS”) No. 167, Amendments to FASB Interpretation No. 46(R), is included in the
Consolidation Topic of the FASB Accounting Standards Codification (“ASC”). The revised guidance eliminates
the concept of a qualifying special-purpose entity and replaces the quantitative-based risks and rewards
calculation of the previous guidance for determining which company, if any, has a controlling financial interest
in a variable interest entity. The revised guidance requires an analysis of whether a company has: (1) the power
to direct
the entity’s economic
performance and (2) the obligation to absorb the losses that could potentially be significant to the entity or the
right to receive benefits from the entity that could potentially be significant to the entity. An entity is required to
be re-evaluated as a variable interest entity when the holders of the equity investment at risk, as a group, lose the
power from voting rights or similar rights to direct the activities that most significantly impact the entity’s
economic performance. Additional disclosures are required about a company’s involvement in variable interest
entities and an ongoing assessment of whether a company is the primary beneficiary. The adoption of the new
guidance effective January 1, 2010 had no effect on the Company’s consolidated financial statements.

the activities of a variable interest entity that most significantly impact

Improving Disclosures about Fair Value Measurements

In January 2010,

the FASB issued guidance to improve the disclosures related to fair value
measurements. The new guidance requires expanded fair value disclosures, including the reasons for significant
transfers between Level 1 and Level 2 and the amount of significant transfers into each level disclosed separately
from transfers out of each level. For Level 3 fair value measurements, information in the reconciliation of
recurring Level 3 measurements about purchases, sales, issuances and settlements shall be presented separately
on a gross basis, rather than as one net number. In addition, clarification is provided about existing disclosure
requirements, such as presenting fair value measurement disclosures for each class of assets and liabilities that
are determined based on their nature and risk characteristics and their placement in the fair value hierarchy (that
is, Level 1, 2, or 3), as opposed to each major category of assets and liabilities, as required in the previous
guidance. Disclosures about the valuation techniques and inputs used to measure fair value for both recurring and
nonrecurring fair value measurements are required for fair value measurement that fall in either Level 2 or Level
3. The Company adopted this new guidance effective January 1, 2010, except for the gross presentation of
purchases, sales, issuances and settlements in the Level 3 reconciliation, which is effective for annual and interim
reporting periods beginning after December 15, 2010. The disclosures required by this new guidance are
provided in the accompanying Note 3.

Other-Than-Temporary Impairments

In April 2009, the FASB issued guidance for the accounting for other-than-temporary impairments. Under
the guidance, which is part of the FASB ASC Topic Investments – Debt and Equity Securities, the indicators
used in considering an impairment of a debt security to be other-than-temporary were modified, from
management asserting it has both the intent and the ability to hold an impaired security for a period of time
sufficient for anticipated recovery in fair value to management asserting that (a) it does not have the intent to sell
the security and (b) it is more likely than not it will not have to sell the security before recovery. Additionally,
this guidance requires that other-than-temporary impairments on debt securities due to credit be recognized in

STATE AUTO FINANCIAL CORPORATION AND SUBSIDIARIES

Notes to Consolidated Financial Statements, Continued

earnings while non-credit other-than-temporary impairments be recognized in other comprehensive income. This
guidance also requires companies to disclose major security types for both debt and equity securities and to
provide meaningful disclosure about individually significant unrealized losses and all such disclosures are
required to be included in both interim and annual periods. The Company adopted this guidance effective April 1,
2009, and determined it did not have a material effect on the Company’s consolidated financial statements. The
disclosures required by this guidance are provided in Note 2.

Pending Adoption of Accounting Pronouncements

Accounting for Costs Associated with Acquiring or Renewing Insurance Contracts

In October 2010, the FASB issued updated guidance to address diversity in practice for the accounting of
costs associated with acquiring or renewing insurance contracts. This guidance modifies the definition of
acquisition costs to specify that a cost be directly related to the successful acquisition of a new or renewal
insurance contract in order to be deferred. The new guidance is effective on a prospective basis for fiscal years
beginning after December 15, 2011, with early adoption permitted. Retrospective application is also permitted,
but not required. The Company is still assessing the impact the provisions of the new guidance will have on its
consolidated financial statements.

3. Fair Value of Financial Instruments

Below is the fair value hierarchy that categorizes into three levels the inputs to valuation techniques that are

used to measure fair value:

•

•

•

Level 1 includes observable inputs which reflect quoted prices for identical assets or liabilities in active
markets at the measurement date.

Level 2 includes observable inputs for assets or liabilities other than quoted prices included in Level 1,
and it includes valuation techniques which use prices for similar assets and liabilities.

Level 3 includes unobservable inputs which reflect the reporting entity’s estimates of the assumptions
that market participants would use in pricing the asset or liability (including assumptions about risk).

The Company utilizes one nationally recognized pricing service to estimate the majority of
its
available-for-sale investment portfolio’s fair value. The Company obtains one price per security and the
processes and control procedures employed by the Company are designed to ensure the value is accurately
the Company gains an
recorded on an unadjusted basis. Through discussions with the pricing service,

97

3/9/11   9:32 PM

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

Notes to Consolidated Financial Statements, Continued

understanding of the methodologies used to price the different types of securities, that the data and the valuation
methods utilized are appropriate and consistently applied, and that
the assumptions are reasonable and
representative of fair value. To validate the reasonableness of the valuations obtained from the pricing service,
the Company compares to other fair value pricing information gathered from other independent pricing sources.
At December 31, 2010, the Company did not adjust any of the prices received from the pricing service.

Transfers between level categorizations may occur due to changes in the availability of market observable
inputs. Transfers in and out of level categorizations are reported as having occurred at the beginning of the
quarter in which the transfer occurred. There were no transfers between level categorizations during the years
ended December 31, 2010 and 2009, other than within other invested assets as described below.

The following sections describe the valuation methods used by the Company for each type of financial

instrument carried at fair value:

Fixed Maturities

The Company utilizes a pricing service to estimate fair value measurements for the majority of its fixed
maturities. The fair value estimate of the Company’s fixed maturity investments are determined by evaluations
that are based on observable market information rather than market quotes. Inputs to the evaluations include, but
are not limited to, market prices from recently completed transactions and transactions of comparable securities,
interest rate yield curves, credit spreads, and other market-observable information. Investments valued using
these inputs include U.S. treasury securities and obligations of U.S. government agencies, obligations of states
and political subdivisions, corporate securities (except for one security discussed below), and U.S. government
agencies residential mortgage-backed securities. All unadjusted estimates of fair value for fixed maturities priced
by the pricing service are included in the amounts disclosed in Level 2 of the hierarchy. If market inputs are
unavailable, then no fair value is provided by the pricing service. For these securities, fair value is determined
either by requesting brokers who are knowledgeable about these securities to provide a quote; or the Company
internally determines the fair values by employing widely accepted pricing valuation models, and depending on
the level of observable market inputs, renders the fair value estimate as Level 2 or Level 3. The Company holds
one fixed maturity corporate security for which the Company estimates the fair value of this security using the
present value of the future cash flows. Due to the limited amount of observable market information, the
Company includes the fair value estimates for this security in Level 3.

Equities

The fair value of each equity security is based on an observable market price for an identical asset in an
active market and is priced by the same pricing service discussed above. All equity securities are recorded using
unadjusted market prices and have been disclosed in Level 1.

Other Invested Assets

Included in other invested assets are two international private equity funds (“the funds”) that invest in equity
securities of foreign issuers and are managed by third party investment managers. The funds had a fair value of
$75.3 million and $48.3 million at December 31, 2010 and 2009, respectively, which was determined using each
fund’s net asset value. The Company employs procedures to assess the reasonableness of the fair value of the
funds including obtaining and reviewing each fund’s audited financial statements. There are no unfunded
commitments related to the funds. The Company may not sell its investment in the funds; however, the Company

may redeem all or a portion of its investment in the funds at net asset value per share with the appropriate prior
written notice. As of October 1, 2009, the Company adopted the FASB’s guidance related to fair value
measurements and disclosures of investments in certain entities that calculate net asset value per share (or its
equivalent). This guidance classified the fair value measurements of the funds as a Level 2 within the hierarchy
due to the Company’s ability to redeem its investment in the funds at net asset value per share at the
measurement date. The funds, which were historically classified as a Level 3, were transferred out of Level 3 and
into Level 2 as of October 1, 2009.

The remainder of the Company’s other invested assets consist primarily of holdings in publicly-traded
mutual funds. The Company believes that its prices for these publicly-traded mutual funds based on an
observable market price for an identical asset in an active market reflect their fair values and consequently these
securities have been disclosed in Level 1.

The following tables set forth the Company’s available-for-sale investments within the fair value hierarchy

at December 31, 2010 and 2009:

The Company recorded favorable loss and loss expense reserve development in 2010, 2009 and 2008 of
$64.6 million, $56.2 million and $27.3 million, respectively. The favorable development was the result of
subsequent reserve reviews using more mature claim data. Favorable development of loss adjustment expenses
contributed approximately $12.7 million of the 2010 development. Of the remaining favorable development in

2010, $10.7 million, $10.4 million and $9.0 million was attributable to auto liability, both personal and
commercial, homeowners and fire & allied lines, respectively. The favorable development in these lines was
driven by emergence of lower than anticipated claim severity, as well as lower than anticipated claim frequency
for fire & allied lines. Much of the favorable development was attributable to the 2009 and, to a lesser extent,
2008 accident years.

Favorable development

loss adjustment expense and catastrophe losses contributed
approximately $10.9 million each. Of the remaining favorable development in 2009, $9.5 million and $8.3
million was attributable to auto liability, both personal and commercial, and other & product
liability,
respectively. The favorable development in those lines was driven by emergence of lower than anticipated claim
severity, as well as lower than anticipated claim frequency for other & product liability.

Approximately half of the 2008 favorable development was attributable to loss adjustment expense being
lower than anticipated. The remainder was primarily attributable to favorable emergence of catastrophe losses as
well as non-catastrophe homeowners losses, where claims severity emerged lower than anticipated.

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.

6. Transactions with Affiliates

a. Reinsurance

Since 1991, the insurance subsidiaries of State Auto Financial have participated in a quota share reinsurance
pooling arrangement (“the Pooling Arrangement”) with State Auto Mutual and its subsidiaries and affiliates,
State Auto Insurance Company of Wisconsin (“SA Wisconsin”), State Auto Florida Insurance Company (“SA
Florida”), Meridian Citizens Mutual Insurance Company (“Meridian Citizens Mutual”) and Meridian Security
Insurance Company (“Meridian Security”). As of January 1, 2008, the Pooling Arrangement was amended to add
Beacon National Insurance Company (“Beacon National”), Patrons Mutual Insurance Company of Connecticut
(“Patrons Mutual”), Litchfield Mutual Fire Insurance Company (“Litchfield”) and the middle market business
written by State Auto Mutual and Meridian Security to the pool. As of January 1, 2010, the Pooling Arrangement
was further amended to add SA National and to include voluntary assumed reinsurance from third parties
unaffiliated with the pool participants that was assumed on or after January 1, 2009 to the pool. State Auto P&C,
Milbank, Farmers, SA Ohio and SA National are referred to as the “STFC Pooled Companies,” and State Auto
Mutual, SA Wisconsin, SA Florida, Meridian Citizens Mutual, Meridian Security, Beacon National, Patrons
Mutual and Litchfield are referred to as the “Mutual Pooled Companies.”

In conjunction with the January 1, 2008 Pooling Arrangement amendment, the STFC Pooled Companies

received $92.0 million in cash, for additional net insurance liabilities assumed on January 1, 2008.

In conjunction with the January 1, 2010 Pooling Arrangement amendment, the STFC Pooled Companies
received $3.7 million in cash from the Mutual Pooled Companies for net insurance assets transferred on
January 1, 2010. The following table sets forth the impact on the Company’s balance sheet at January 1, 2010,

In general, under the Pooling Arrangement, the STFC Pooled Companies and the Mutual Pooled Companies
other than State Auto Mutual 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 has been at 80% since 2001. All premiums, losses
and loss expenses and underwriting expenses are allocated among the participants on the basis of each
Company’s participation percentage in the Pooling Arrangement. The Pooling Arrangement provides
indemnification against loss or liability relating to insurance risk and has been accounted for as reinsurance.

The Pooling Arrangement does not relieve each individual pooled subsidiary of its primary liability as the
originating insurer; consequently, there is a concentration of credit risk arising from business ceded to State Auto
Mutual. As the Pooling Arrangement provides for the right of offset, the Company has reported losses and loss

Arrangement have an A.M. Best rating of A+ (Superior).

Notes to Consolidated Financial Statements, Continued

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 members 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, 2010 and 2009 is approximately $330.7 million and $320.2 million, respectively.

b. Notes Payable

In May 2003, State Auto Financial formed a Delaware business trust (the “Capital Trust”) to issue $15.0
million of mandatorily redeemable preferred capital securities to a third party and $0.5 million of common
securities to State Auto Financial (the capital and common securities are collectively referred to as the “Trust
Securities”). The Capital Trust loaned $15.5 million, the 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 and interest accrued thereon are the Capital Trust’s
only assets. Interest on the Trust Securities are payable quarterly at a rate equal to the three-month LIBOR rate
plus 4.20% adjusted quarterly (total 4.50% at December 31, 2010). Because 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, 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 2008. 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 to be 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 accordance with the Consolidation Topic of the FASB ASC,
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. See Note 7.

c. Notes Receivable

In May 2009, the Company entered into two separate credit agreements with State Auto Mutual pursuant to
which it loaned State Auto Mutual a total of $70.0 million. Interest is payable semi-annually at a fixed annual
interest rate of 7.00%, with the principal payable in May 2019. There is no prepayment penalty, and no collateral
was given as security for the payment of this loan.

Under these agreements, State Auto Financial earned interest of $4.9 million and $3.1 million for the years
ended December 31, 2010 and 2009, respectively. Interest income is included in net investment income on the
consolidated statements of income.

d. 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
$1.6 million, $1.6 million and $2.5 million in 2010, 2009 and 2008, respectively, and is included in other income
(affiliates) on the consolidated statements of income.

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. State Auto Financial incurred $1.5 million in issuance costs related to the Senior Notes,
which is recorded in other assets on the consolidated balance sheets and is being amortized into interest expense
($0.1 million each for 2010, 2009 and 2008) as the underlying interest expense is recognized on the Senior Notes.

State Auto Financial has a credit facility (the “Credit Facility”) with a syndicate of financial institutions.
The Credit Facility provides for a $100.0 million unsecured revolving credit facility maturing in July 2012. The
Credit Facility is available for general corporate purposes and provides for interest-only payments during its
term, with principal due in full at maturity. Interest is based on a London interbank market rate or a base rate plus
a calculated margin amount. The Credit Facility includes 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, 2010, the Company had not made any borrowings and was in compliance with all covenants
related to the Credit Facility. State Auto Financial incurred $0.5 million in issuance costs related to the Credit
Facility, which is recorded in other assets on the consolidated balance sheets and is being amortized into expense
($0.1 million for 2010, 2009 and 2008) over the term of the Credit Facility.

If the Company determines it is more likely than not that any of its deferred tax assets will not result in
future tax benefits, a valuation allowance must be established for the portion of these assets that are not expected
to be realized. Although realization of deferred tax assets is not assured, based upon a review of all available
evidence, both positive and negative, including the Company’s historical and anticipated future taxable income,
the Company’s management concluded that it is more likely than not that the net deferred income tax assets will
be realized. No valuation allowance was held at December 31, 2010 or 2009.

At December 31, 2010, the Company had $11.5 million of net operating loss carryforwards which, if not

used, will expire in 2030.

At December 31, 2010, the Company carried no balance for uncertain tax positions. The Company had no

accrual for the payment of interest and penalties at December 31, 2010 or 2009.

State Auto Financial and its subsidiaries file a consolidated U.S. federal income tax return. State Auto
Financial and its subsidiaries also file in various state jurisdictions. The Company is no longer subject to U.S.
federal or state and local income tax examinations by tax authorities for years before 2007. However, the
Company is currently under audit by the Internal Revenue Service for the 2009 and 2008 tax years, as required
by the Congressional Joint Committee on Taxation due to refunds in excess of the $2.0 million threshold. The
audit is anticipated to continue through 2012, and will include a limited scope examination for all tax years
impacted by the net operating loss carrybacks, including tax years 2005 through 2009.

9. Restructuring Costs

In June 2009, the Company initiated a plan to restructure its field and claims operations. Restructuring
charges, including employee termination benefits, relocation packages, and costs associated with ceasing to use
leased properties, related to this reorganization have been recognized in accordance with the Exit or Disposal
Cost Obligations Topic of the FASB ASC. Consideration of this restructuring resulted in a curtailment of the
Company’s pension and postretirement benefit plans as of June 30, 2009, due to the elimination of expected
years of future services of those impacted employees. The Company recognized restructuring costs totaling $2.3
million and $4.8 million during the years ended December 31, 2010 and 2009, respectively. The restructuring
was complete as of December 31, 2010, except for estimated relocation costs of $0.3 million to be recognized in
2011. These charges are included in losses and loss expenses and acquisition and operating expenses on the
condensed consolidated statements of income.

10. Pension and Postretirement Benefit Plans

The Company, through the employees of 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 hired prior to January 1, 2010 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 hired prior to January 1, 2010 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.”

Effective January 1, 2008, the Company adopted the measurement date requirement under transition
alternative method one, as defined in SFAS No. 158 (codified in the Compensation – Retirement Benefits Topic
of the FASB ASC), moving from a September 30 measurement date to a December 31 date for measuring its
benefit plan obligations. This transition method resulted in a one-time adjustment that decreased beginning
retained earnings by $2.4 million, net of tax. The combined impact of the measurement date transition and
re-measurement of plan assets and obligations on January 1, 2008,
increased beginning accumulated
comprehensive income by $3.5 million, net of tax.

In November 2009, the Company announced to its employees a one-time election to select between two
retirement benefit options: to either continue participation in the existing defined benefit pension plan with no
changes; or to choose a new defined contribution plan in which the Company automatically contributes a
percentage of the employee’s annual income resulting in a freeze to the employee’s existing accrued defined
pension benefit. On May 31, 2010, employees’ elections were finalized which resulted in a $2.4 million
curtailment on this date.

Due to the curtailment resulting from the employee one-time pension benefit election, the expense was remeasured at May 31, 2010,
using discount rate of 5.75%.

** Due to the curtailment resulting from the restructuring, the expense was remeasured at June 30, 2009, using discount rate of 6.25% and

expected long-term rate of return on assets of 8.00%.

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 plans’ 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. One of the goals of diversifying the benefit plans’
portfolio among different asset classes
risk in one asset
class. Management has investment policy guidelines with respect to limiting the ownership in any single debt or
equity issuer, and the international private equity investments are composed of numerous securities to reduce our
exposure to a single issuer. The following table sets forth the asset allocation targets, as a percentage of total fair
value, which are used as a guide by management when allocating funds as they become available.

See Note 3 for the valuation methods used by the Company for each type of financial instrument the plans
hold that are carried at fair value. There were no transfers between level categorizations during the years ended
December 31, 2010 and 2009, other than international instruments that were transferred from a Level 3 to a Level
2 due to the adoption of the FASB’s guidance related to fair value measurements and disclosures of investments
in certain entities that calculate net asset value per share in 2009, as described in Note 3.

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 up to $15.0 million during 2011 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 1% of contributions of participants’ salary at the rate of one dollar for each dollar
contributed. Participant contributions of 2% to 6% are matched at a rate of 50 cents for each dollar contributed.
In addition, the Company contributes a percentage of the employee’s annual income for those employees hired
on or after January 1, 2010, and for those employees hired prior to January 1, 2010 who chose to freeze their
existing accrued pension benefit effective June 30, 2010. The Company’s share of the expense under the plan
totaled $3.3 million, $3.3 million and $3.1 million for 2010, 2009 and 2008, respectively.

11. 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 (the “Repurchase Plan”). This program ended on December 31, 2009. Under the Repurchase Plan, State
Auto Financial repurchased shares from State Auto Mutual in amounts that were proportional to the respective
current ownership percentages of State Auto Mutual, which was approximately 64%, and other shareholders.
State Auto Financial did not repurchase any shares in 2009 and had total share repurchase activity in 2008 of
approximately 1.2 million common shares. For the lifetime of the Repurchase Plan, approximately 2.0 million
common shares were purchased at an average repurchase price of $27.26 per share for a total cost of $55.3
million.

Notes to Consolidated Financial Statements, Continued

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.

13. Share-Based Compensation

The Company maintains share-based compensation plans for key employees and outside, or non-employee,
directors. The share-based compensation plan for key employees is the State Auto Financial Corporation 2009
Equity Compensation Plan (the “Equity Plan”). This plan replaced the previous equity plan which expired on
July 1, 2010. The stock-based compensation plan for outside directors is the Outside Directors Restricted Share
Unit Plan (the “RSU Plan”).

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.

The Equity Plan provides for the award of qualified and nonqualified stock options, restricted shares,
performance shares, performance units and other stock-based awards. The Company has reserved 2.0 million
common shares under the Equity Plan. As of December 31, 2010, a total of 1.4 million common shares are
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 one individual is 250,000 shares. The Equity Plan automatically terminates on May 8,
2019.

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 2010,
2009 and 2008 were 0.6 million, 0.4 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.

As of December 31, 2010, there was $0.2 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 2.25 years.

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%
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, 2010, a total of 2.8 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 RSU Plan is an unfunded deferred compensation plan which currently provides each outside director
with an award of 1,400 restricted share units (the “RSU award”) following each annual meeting of shareholders.
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 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 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 RSU Plan automatically terminates on May 31, 2015.
The Company accounts for the RSU Plan as a liability plan. There were 24,268 RSUs, 14,800 RSUs, and 11,200
RSUs granted in 2010, 2009 and 2008, respectively.

During 2010 and 2009, common shares valued at approximately $39,000 and $5,300, respectively, were

distributed by the Company under the RSU Plan.

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 2010, 2009
and 2008. 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 approximating the expected life of the option.

The fair value of share-based awards granted to employees was estimated at the date of grant using the
Black-Scholes option-pricing model. The following table sets forth the weighted average fair values and related
assumptions for options granted for the years ended December 31, 2010, 2009 and 2008:

16. Reportable Segments

At December 31, 2010, the Company has three 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 Midwestern, Southern, Southwestern, and Eastern United States. The personal
insurance segment provides primarily personal automobile and homeowners to the personal insurance market.
The business insurance segment provides primarily commercial automobile, commercial multi-peril, fire & allied
lines, other & product liability and workers’ compensation insurance to small-to-medium sized businesses within
the commercial insurance market. These products are primarily distributed through the independent insurance
agency system. The investment operations segment, managed by Stateco, provides investment services.

In 2010, the Company focused on reassessing and positioning a realignment of its internal organization to be
more strategic in the personal, business and specialty insurance markets. Considering these internal changes
along with changes to the Pooling Arrangement as of January, 1, 2011 (see Note 19), beginning with the first
quarter of 2011, the Company’s reportable insurance segments will change from personal and business insurance
to personal insurance, business insurance and specialty insurance. Prior reporting periods will be conformed to
the new segment presentation.

The Company evaluates the performance of its insurance segments using industry financial measurements
based on 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. The investment
operations segment is evaluated based on investment returns of assets managed by Stateco.

Asset information by segment is not reported for the insurance segments because the Company does not

produce such information internally.

18. Contingencies

The Company is involved in a number of lawsuits, and may become involved in other potential litigation,
arising in the ordinary course of its business. Generally, the Company’s involvement in a lawsuit involves
defending third-party claims brought against its insureds in its role as liability insurer or against the Company as
a principal of surety bonds, as well as defending policy coverage claims brought against the Company. The
Company considers all lawsuits relating to such insurance claims in establishing the Company’s loss and loss
adjustment expense reserves.

The following describes the significant pending legal proceedings, other than ordinary routine litigation
incidental to our business, to which State Auto Financial or any of its subsidiaries is a party or to which any of
our property is subject:

In December 2010, a putative class action lawsuit (Kelly vs. State Automobile Mutual Insurance
Company, et al.) was filed against State Auto Financial, State Auto P&C and State Auto Mutual in state
court in Ohio. In this lawsuit, plaintiffs allege that the State Auto Group has engaged, and continues to
engage, in deceptive practices by failing to disclose to plaintiffs the availability, through one or more related
companies, of insurance policies providing for identical coverage and service as those policies purchased by
plaintiffs but at a lower premium amount. Plaintiffs are seeking class certification and compensatory and
punitive damages to be determined by the court and restitution and/or disgorgement of profits derived from
plaintiffs and the alleged class. The Company filed a motion to dismiss on March 1, 2011, and it remains

STATE AUTO FINANCIAL CORPORATION AND SUBSIDIARIES

Notes to Consolidated Financial Statements, Continued

pending. The Company believes its practices with respect to pricing, quoting and selling its insurance
policies are in compliance with all applicable laws, deny any and all liability to plaintiffs or the alleged
class, and intends to vigorously defend this lawsuit.

In accordance with the Contingencies Topic of the FASB ASC, the Company accrues for a litigation-related
liability, other than insurance claims, when it is probable that such a liability has been incurred and the amount of
the loss can be reasonably estimated. Based on currently available information known to the Company, the
Company believes that its reserves for these litigation-related liabilities are reasonable and that the ultimate
outcomes of any pending matters are not likely to have a material adverse effect on its consolidated financial
position or results of operations. However, regarding the putative class action litigation described above, it is not
currently possible to predict the legal outcome of this litigation or its impact on the future development of claims
and litigation relating to similar claims. Any such development will be affected by future court decisions and
interpretations. Because of these uncertainties, additional liabilities may arise in amounts in excess of our
currently held reserves. In addition, the Company’s estimate of ultimate claims and claim adjustment expenses
may change. These additional liabilities or increases in estimates, or a range of either, cannot now be reasonably
estimated and could result in income statement charges that could be material to the Company’s results of
operations in future periods.

Additionally, the Company may be impacted by adverse regulatory actions and adverse court decisions
where insurance coverages are expanded beyond the scope originally contemplated in its insurance policies. The
Company believes that the effects, if any, of such regulatory actions and published court decisions are not likely
to have a material adverse effect on its financial position or results from operations.

19. Subsequent Events

As of January 1, 2011, the Pooling Arrangement was amended to add Rockhill Insurance Company, Plaza
Insurance Company, American Compensation Insurance Company and Bloomington Compensation Insurance
Company, each of which are subsidiaries of State Auto Mutual (collectively, the “Rockhill Insurers”), to the
pool, each with a participation percentage of 0.0%.

In conjunction with this amendment, the STFC Pooled Companies will receive approximately $150.9
million in cash and/or investment securities from the Rockhill Insurers, for net insurance liabilities transferred on
January 1, 2011. The following table sets forth an estimate of the impact on the Company’s balance sheet at
January 1, 2011, relating to this Pooling Arrangement amendment:

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 on Internal Control over Financial Reporting” 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, 2010, and has concluded that such internal control over financial reporting was effective.

5.

Ernst & Young LLP, the independent registered public accounting firm that audited the consolidated
financial statements included in this Form 10-K, has issued their attestation on the Company’s internal
control over financial reporting, which is included herein.

Disclosure Controls and Procedures

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

Changes in Internal Control over Financial Reporting

There 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.
