About the 
CompAny

Cincinnati Financial Corporation stands among the 25 largest property casualty insurers in the 

nation, based on premium volume. A select group of independent agencies actively markets our 

business, home and auto insurance within their communities. These agents offer our standard 

market commercial lines policies in 39 states, personal lines policies in 29 and excess and surplus 

lines policies in 38 of those same states. Within this select group, we seek to become the life 

insurance carrier of choice and to help agents and their clients – our policyholders – by offering 

leasing and financing services. 

For 60 years, three competitive advantages have distinguished our company, positioning us to 

build value and long-term success: 

•  Commitment to our network of professional independent insurance agencies   

and to their continued success

•  Financial strength that lets us be a consistent market for our agents’ business,   

supporting stability and confidence

•  Operating structure that supports local decision making, showcasing the strength of our  

claims service, field underwriting and field support services

These advantages help us to balance growth with underwriting discipline in a competitive 

environment. Learn more about where we are today and how we plan to create value for

Business 

Item 1. 
CINCINNATI FINANCIAL CORPORATION – INTRODUCTION 
We are an Ohio corporation formed in 1968. Our lead subsidiary, The Cincinnati Insurance Company, was 
founded in 1950. Our main business is property casualty insurance marketed through independent 
insurance agents in 39 states. Our headquarters is in Fairfield, Ohio. At year-end 2010, we employed 
4,060 associates, with 2,838 headquarters associates providing support to 1,222 field associates. 
At year-end 2010, Cincinnati Financial Corporation owned 100 percent of three subsidiaries: The Cincinnati 
Insurance Company, CSU Producer Resources Inc., and CFC Investment Company. In addition, the parent 
company has an investment portfolio, owns the headquarters property and is responsible for corporate 
borrowings and shareholder dividends.  
The Cincinnati Insurance Company owns 100 percent of our four additional insurance subsidiaries. Our 
standard market property casualty insurance group includes two of those subsidiaries – The Cincinnati 
Casualty Company and The Cincinnati Indemnity Company. This group writes a broad range of business, 
homeowner and auto policies. Other subsidiaries of The Cincinnati Insurance Company include The Cincinnati 
Life Insurance Company, which provides life insurance, disability income policies and annuities, and The 
Cincinnati Specialty Underwriters Insurance Company, which began offering excess and surplus lines 
insurance products in January 2008.  
The two non-insurance subsidiaries of Cincinnati Financial Corporation are CSU Producer Resources, which 
offers insurance brokerage services to our independent agencies so their clients can access our excess and 
surplus lines insurance products; and CFC Investment Company, which offers commercial leasing and 
financing services to our agencies, their clients and other customers.  
Our filings with the U.S. Securities and Exchange Commission (SEC) are available, free of charge, on our 
website, www.cinfin.com/investors, as soon as possible after they have been filed with the SEC. These filings 
include annual reports on Form 10-K, quarterly reports on Form 10-Q, current reports on Form 8-K and 
amendments to those reports filed or furnished pursuant to Section 13(a) or 15(d) of the Securities 
Exchange Act of 1934. In the following pages we reference various websites. These websites, including our 
own, are not incorporated by reference in this Annual Report on Form 10-K. 
Periodically, we refer to estimated industry data so that we can give information about our performance 
versus the overall insurance industry. Unless otherwise noted, the industry data is prepared by A.M. Best Co., 
a leading insurance industry statistical, analytical and insurer financial strength and credit rating 
organization. Information from A.M. Best is presented on a statutory accounting basis. When we provide our 
results on a comparable statutory accounting basis, we label it as such; all other company data is presented 
in accordance with accounting principles generally accepted in the United States of America (GAAP). 
OUR BUSINESS AND OUR STRATEGY  
INTRODUCTION 
The Cincinnati Insurance Company was founded over 60 years ago by four independent insurance agents. 
They established the mission that continues to guide all of the companies in the Cincinnati Financial 
Corporation family – to grow profitably and enhance the ability of local independent insurance agents to 
deliver quality financial protection to the people and businesses they serve by: 
• 
• 
•  developing associates committed to superior service 
A select group of agencies in 39 states actively markets our property casualty insurance within their 
communities. Standard market commercial lines policies are marketed in all of those states, while personal 
lines policies are marketed in 29 of those states. Excess and surplus lines policies are available in 38 of 
those states. Within this select group, we also seek to become the life insurance carrier of choice and to help 
agents and their clients – our policyholders – by offering leasing and financing services. 

producing competitive, up-to-date products and services 

providing market stability through financial strength 

Cincinnati Financial Corporation – 2010 10-K – Page 3 

Three competitive advantages distinguish our company, positioning us to build shareholder value and to be 
successful overall: 
•  Commitment to our network of professional independent insurance agencies and to their continued 

success 

• 

Financial strength that lets us be a consistent market for our agents’ business, supporting stability 
and confidence  

•  Operating structure that supports local decision making, showcasing our claims excellence and allowing 

independent agents, who represent multiple carriers 

focus on one or more states or regions (regional carrier) 

captive agents, who represent one carrier exclusively, or  

target a certain segment of the market (for example, personal insurance)  

choose to sell a limited product line or only one type of insurance (monoline carrier) 

us to balance growth with underwriting discipline  
Independent Insurance Agency Marketplace 
The U.S. property casualty insurance industry is a highly competitive marketplace with more than 2,000 stock 
and mutual companies operating independently or in groups. No single company or group dominates across 
all product lines and states. Standard market insurance companies (carriers) can market a broad array of 
products nationally or:  
• 
• 
• 
Standard market property casualty insurers generally offer insurance products through one or more 
distribution channels:  
• 
• 
•  direct marketing to consumers  
For the most part, we compete with standard market insurance companies that market through independent 
insurance agents. Agencies marketing our commercial lines products typically represent six to 12 standard 
market insurance carriers for commercial lines products, including both national and regional carriers, most 
of which are mutual companies. Our agencies typically represent four to six standard personal lines carriers, 
and we also compete with carriers that market personal lines products through captive agents and direct 
writers. Distribution through independent insurance agents or brokers represents nearly 60 percent of overall 
U.S. property casualty insurance premiums and approximately 80 percent of commercial property casualty 
insurance premiums, according to studies by the Independent Insurance Agents and Brokers of America. 
We are committed exclusively to the independent agency channel. The independent agencies that we choose 
to market our standard lines insurance products share our philosophies. They do business person to person; 
offer broad, value-added services; maintain sound balance sheets; and manage their agencies 
professionally. We develop our relationships with agencies that are active in their local communities, 
providing important knowledge of local market trends, opportunities and challenges.  
In addition to providing standard market property casualty insurance products, we opened our own excess 
and surplus lines insurance brokerage firm so that we could offer our excess and surplus lines products 
exclusively to the independent agencies who market our other property casualty insurance products. We also 
market life insurance products through the agencies that market our property casualty products and through 
other independent agencies that represent The Cincinnati Life Insurance Company without also representing 
our other subsidiaries. Offering insurance solutions beyond our standard market property casualty insurance 
products helps our agencies meet the broader needs of their clients, and also serves to increase and 
diversify agency revenues and profitability. 
The excess and surplus lines market exists due to a regulatory distinction. Generally, excess and surplus 
lines insurance carriers provide insurance that is unavailable in the standard market due to market 
conditions or characteristics of the insured person or organization that are caused by nature, the insured's 
claim history or the characteristics of their business. We established an excess and surplus lines operation in 
response to requests to help meet the needs of agency clients when insurance is unavailable in the standard 
market. By providing superior service, we can help our agencies grow while also profitably growing our 
property casualty business. Insurers operating in the excess and surplus lines marketplace generally market 
business through excess and surplus lines insurance brokers, whether they are small specialty insurers or 
specialized divisions of larger insurance organizations. 
At year-end 2010, our 1,245 property casualty agency relationships were marketing our standard market 
insurance products out of 1,544 reporting locations. An increasing number of agencies have multiple, 
separately identifiable locations, reflecting their growth and consolidation of ownership within the 
independent agency marketplace. The number of reporting agency locations indicates our agents’ regional 
scope and the extent of our presence within our 39 active states. At year-end 2009, our 1,180 agency 
relationships had 1,463 reporting locations. At year-end 2008, our 1,133 agency relationships had 
1,387 reporting locations.  

Cincinnati Financial Corporation – 2010 10-K – Page 4 

We made 93, 87 and 76 new agency appointments in 2010, 2009 and 2008, respectively. Of these new 
appointments, 70, 65 and 52, respectively, were new relationships. The remainder included new branch 
offices opened by existing Cincinnati agencies and appointment of agencies that merged with a Cincinnati 
agency. These new appointments and other changes in agency structures or appointment status led to a net 
increase in agency relationships of 65, 47 and 41 and a net increase in reporting agency locations of 81, 
76 and 60 in 2010, 2009 and 2008, respectively. 
On average, we have a 12.4 percent share of the standard lines property casualty insurance purchased 
through our reporting agency locations. Our share is 17.7 percent in reporting agency locations that have 
represented us for more than 10 years; 6.7 percent in agencies that have represented us for six to 10 years; 
4.1 percent in agencies that have represented us for one to five years; and 0.8 percent in agencies that have 
represented us for less than one year. 
Our largest single agency relationship accounted for approximately 1.2 percent of our total property casualty 
earned premiums in 2010. No aggregate locations under a single ownership structure accounted for more 
than 2.2 percent of our earned premiums in 2010.  
Financial Strength 
We believe that our financial strength and strong surplus position, reflected in our insurer financial strength 
ratings, are clear, competitive advantages in the segments of the insurance marketplace that we serve. This 
strength supports the consistent, predictable performance that our policyholders, agents, associates and 
shareholders have always expected and received, helping us withstand significant challenges.  
While the prospect exists for short-term financial performance variability due to our exposures to potential 
catastrophes or significant capital market losses, the rating agencies consistently have asserted that we 
have built appropriate financial strength and flexibility to manage that variability. We remain committed to 
strategies that emphasize being a consistent, stable market for our agents’ business over short-term benefits 
that might accrue by quick, opportunistic reaction to changes in market conditions. 
We use various principles and practices such as diversification and enterprise risk management to maintain 
strong capital. This includes maintaining a diversified investment portfolio by reviewing and applying 
diversification parameters and tolerances. 
•  Our $8.383 billion fixed-maturity portfolio is diversified and exceeds total insurance reserves. At 

December 31, 2010, no corporate bond exposure accounted for more than 0.8 percent of our fixed-
maturity portfolio and no municipal exposure accounted for more than 0.3 percent. The portfolio had an 
average rating of A2/A and its fair value exceeded total insurance reserve liability by approximately 
35 percent.  

• 

The strength of our fixed-maturity portfolio provides an opportunity to invest for potential capital 
appreciation by purchasing equity securities. Our $3.041 billion equity portfolio minimizes 
concentrations in single stocks or industries. At December 31, 2010, no single security accounted for 
more than 6 percent of our portfolio of publicly traded common stocks, and no single sector accounted 
for more than 16 percent.  

Strong liquidity increases our flexibility through all periods to maintain our cash dividend and to continue to 
invest in and expand our insurance operations. At December 31, 2010, we held $1.042 billion of our cash 
and invested assets at the parent company level, of which $763 million, or 73.2 percent, was invested in 
common stocks, and $38 million, or 3.6 percent, was cash or cash equivalents. 
We minimize reliance on debt as a source of capital, maintaining the ratio of debt-to-total-capital below 
20 percent. At December 31, 2010, this ratio at 14.3 percent was well below the target limit as capital 
remained strong while debt levels were unchanged from year-end 2009. Our long-term debt consists of 
three non-convertible, non-callable debentures, two due in 2028 and one in 2034.  
At year-end 2010 and 2009, risk-based capital (RBC) for our standard and excess and surplus lines property 
casualty operations and life operations was very strong, far exceeding regulatory requirements.  
•  We ended 2010 with a 0.8-to-1 ratio of property casualty premiums to surplus, a key measure of 

property casualty insurance company capacity and security. A lower ratio indicates more security for 
policyholders and greater capacity for growth by an insurer. Our low ratio, compared with historical 
averages, gives us ample flexibility to diversify risk by expanding our operations into new geographies 
and product areas. The estimated industry average ratio was 0.7-to-1 for 2010.  

•  We ended 2010 with a 14.1 percent ratio of life statutory adjusted risk-based surplus to liabilities, a key 

measure of life insurance company capital strength. The estimated industry average ratio was 
12.0 percent for 2010. A higher ratio indicates an insurer’s stronger security for policyholders and 
capacity to support business growth.

The consolidated property casualty insurance group’s ratio of investments in common stock to statutory 
surplus was 55.3 percent at year-end 2010 compared with 58.4 percent at year-end 2009. The life 
insurance company’s ratio was 29.6 percent compared with 32.2 percent a year ago.  
Cincinnati Financial Corporation’s senior debt is rated by four independent rating firms. In addition, the rating 
firms award our property casualty and life operations insurer financial strength ratings based on their 
quantitative and qualitative analyses. These ratings assess an insurer’s ability to meet financial obligations to 
policyholders and do not necessarily address all of the matters that may be important to shareholders. 
Ratings may be subject to revision or withdrawal at any time by the ratings agency, and each rating should be 
evaluated independently of any other rating. 
All of our insurance subsidiaries continue to be highly rated. During 2010, Standard & Poor’s Rating Services 
lowered our ratings as described below. No other rating agency actions occurred during 2010. 
As of February 25, 2011, our insurer financial strength ratings were:

On December 13, 2010, A.M. Best affirmed our ratings that it had assigned in February 2010, continuing 
its stable outlook. A.M. Best cited our superior risk-adjusted capitalization, conservative reserving 
philosophy and successful distribution within our targeted regional markets. Concerns noted by A.M. Best 
included geographic concentration, underwriting losses that began in 2008 and common stock leverage 
of approximately 50 percent of statutory surplus. A.M. Best said its concerns are offset by our 
conservative underwriting and reserving philosophies, with loss reserves more than fully covered by a 
highly rated, diversified bond portfolio, and by strategic initiatives to improve underwriting results.  
On September 2, 2010, Fitch Ratings affirmed our ratings that it had assigned in August 2009, 
continuing its stable outlook. Fitch noted that ratings strengths include conservative capitalization, 
moderate holding company leverage, ample liquidity and competitive advantages from our 
distribution system. Fitch said the ratings recognize our steps taken to rebalance our common stock 
portfolio to reduce volatility of capital and earnings. Fitch noted concerns principally related to 
challenges from competitive market conditions and exposure to regional natural catastrophes and 
weather-related losses.

On July 19, 2010, Standard & Poor’s Ratings Services lowered the insurer financial strength ratings to 
A (Strong) from A+ (Strong) on our standard market property casualty companies and our life insurance 
subsidiary, and raised its outlook to stable. S&P said its actions reflected the recent decline in our 
earnings and deterioration of underwriting performance from historical levels. Standard & Poor’s noted 
our very strong capitalization and strong competitive position, supported by a very loyal and productive 
agency force and low-cost infrastructure. S&P also cited our improved enterprise risk management, 
including a more conservative and risk-averse investment portfolio, which supports capital stability.  
Our debt ratings are discussed in Item 7, Liquidity and Capital Resources, Additional Sources of Liquidity, 
Page 79. 
Operating Structure 
We offer our broad array of insurance products through the independent agency channel. We recognize that 
locally based independent agencies have relationships in their communities and local marketplace 
intelligence that can lead to policyholder satisfaction, loyalty and profitable business. We seek to be a 
consistent and predictable property casualty carrier that agencies can rely on to serve their clients. For our 
standard market business, field and headquarters underwriters make risk-specific decisions about both new 
business and renewals.  
In our 10 highest volume states for consolidated property casualty premiums, 956 reporting agency locations 
wrote 67.1 percent of our 2010 consolidated property casualty earned premium volume compared with 
933 locations and 68.1 percent in 2009.

Field Focus  
We rely on our force of 1,222 field associates to provide service and be accountable to our agencies for 
decisions we make at the local level. These associates live in the communities our agents serve, working 
from offices in their homes and providing 24/7 availability to our agents. Headquarters associates also 
provide agencies with underwriting, accounting and technology assistance and training. Company executives, 
headquarters underwriters and special teams regularly travel to visit agencies, strengthening the personal 
relationships we have with these organizations. Agents have opportunities for direct, personal conversations 
with our senior management team, and headquarters associates have opportunities to refresh their 
knowledge of marketplace conditions and field activities. 
The field team is coordinated by field marketing representatives responsible for underwriting new commercial 
lines business. They are joined by field representatives specializing in claims, loss control, personal lines, 
machinery and equipment, bond, premium audit, life insurance and leasing. The field team provides many 
services for agencies and policyholders; for example, our loss control field representatives and others 
specializing in machinery and equipment risks perform inspections and recommend specific actions to 
improve the safety of the policyholder’s operations and the quality of the agent’s account.  
Agents work with us to carefully select risks and assure pricing adequacy. They appreciate the time our 
associates invest in creating solutions for their clients while protecting profitability, whether that means 
working on an individual case or customizing policy terms and conditions that preserve flexibility, choice and

other sales advantages. We seek to develop long-term relationships by understanding the unique needs of 
their clients, who are also our policyholders. 
We also are responsive to agent needs for well designed property casualty products. Our commercial lines 
products are structured to allow flexible combinations of property and liability coverages in a single package 
with a single expiration date and several payment options. This approach brings policyholders convenience, 
discounts and a reduced risk of coverage gaps or disputes. At the same time, it increases account retention 
and saves time and expense for the agency and our company. 
We seek to employ technology solutions and business process improvements that:  
• 

allow our field and headquarters associates to collaborate with each other and with agencies 
more efficiently  

• 

• 

• 

provide our agencies the ability to access our systems and client data to process business transactions 
from their offices  

allow policyholders to directly access pertinent policy information online in order to further improve 
efficiency for our agencies  

automate our internal processes so our associates can spend more time serving agents and 
policyholders, and  

reduce duplicated effort, introducing more efficient processes that reduce company and agency costs 

• 
Agencies access our systems and other electronic services via their agency management systems or 
CinciLink®, our secure agency-only website. CinciLink provides an array of web-based services and content 
that makes doing business with us easier, such as commercial and personal lines rating and processing 
systems, policy loss information, sales and marketing materials, educational courses about our products and 
services, accounting services, and electronic libraries for property and casualty coverage forms and state 
rating manuals. 
Superior Claims Service 
Our claims philosophy reflects our belief that we will prosper as a company by responding to claims person to 
person, paying covered claims promptly, preventing false claims from unfairly adding to overall premiums 
and building financial strength to meet future obligations.  
Our 763 locally based field claims associates work from their homes, assigned to specific agencies. 
They respond personally to policyholders and claimants, typically within 24 hours of receiving an agency’s 
claim report. We believe we have a competitive advantage because of the person-to-person approach and 
the resulting high level of service that our field claims representatives provide. We also help our agencies 
provide prompt service to policyholders by giving agencies authority to immediately pay most first-party 
claims under standard market policies up to $2,500. We believe this same local approach to handling 
claims is a competitive advantage for our agents providing excess and surplus lines coverage in their 
communities. Handling of these claims includes guidance from headquarters-based excess and surplus lines 
claims managers.  
Our property casualty claims operation uses CMS, our claims management system, to streamline processes 
and achieve operational efficiencies. CMS allows field and headquarters claims associates to collaborate on 
reported claims through a virtual claim file. Our field claims representatives use tablet computers to view and 
enter information into CMS from any location, including an insured’s home or agent’s office, and to print 
claim checks using portable printers. Agencies also can access selected CMS information such as activity 
notes on open claims. 
Catastrophe response teams are comprised of volunteers from our experienced field claims staff, and we 
give them the tools and authority they need to do their jobs. In times of widespread loss, our field claims 
representatives confidently and quickly resolve claims, often writing checks on the same day they inspect the 
loss. CMS introduced new efficiencies that are especially evident during catastrophes. Electronic claim files 
allow for fast initial contact of policyholders and easy sharing of information and data by rotating storm 
teams, headquarters and local field claims representatives. When hurricanes or other weather events are 
predicted, we can identify through mapping technologies the expected number of our policyholders that may 
be impacted by the event and choose to have catastrophe response team members travel to strategic 
locations near the expected impact area. They are in position to quickly get to the affected area, set up 
temporary offices and start calling on policyholders. 
Our claims associates work to control costs where appropriate. They use vendor resources that provide 
negotiated pricing to our insureds and claimants. Our field claims representatives also are educated 
continuously on new techniques and repair trends. They can leverage their local knowledge and experience 
with area body shops, which helps them negotiate the right price with any facility the policyholder chooses.  
We staff a Special Investigations Unit (SIU) with former law enforcement and claims professionals whose 
qualifications make them uniquely suited to gathering facts to uncover potential fraud. While we believe our 
job is to pay what is due under each policy contract, we also want to prevent false claims from unfairly 

Cincinnati Financial Corporation – 2010 10-K – Page 8 

increasing overall premiums. Our SIU also operates a computer forensics lab, using sophisticated software to 
recover data and mitigate the cost of computer-related claims for business interruption and loss of records. 
Insurance Products 
We actively market property casualty insurance in 39 states through a select group of independent insurance 
agencies. For most agencies that represent us, we believe we offer insurance solutions for approximately 
75 percent of the typical insurable risks of their clients. Our standard market commercial lines products are 
marketed in all 39 states while our standard market personal lines products are marketed in 29. At year-end 
2010, CSU Producer Resources marketed our excess and surplus lines products in 38 states to agencies 
that represent Cincinnati Insurance. We discuss our commercial lines, personal lines and excess and surplus 
lines insurance operations and products in Commercial Lines Property Casualty Insurance Segment, 
Page 12, Personal Lines Property Casualty Insurance Segment, Page 15, and Excess and Surplus Lines 
Property Casualty Insurance Segment, Page 16.  
The Cincinnati Specialty Underwriters Insurance Company began excess and surplus lines insurance 
operations in January 2008. We structured this operation to exclusively serve the needs of the independent 
agencies that currently market our standard market insurance policies. When all or a portion of a current or 
potential client’s insurance program requires excess and surplus lines coverages, those agencies can write 
the whole account with Cincinnati, gaining benefits not often found in the broader excess and surplus lines 
market. Agencies have access to The Cincinnati Specialty Underwriters Insurance Company’s product line 
through CSU Producer Resources, the wholly owned insurance brokerage subsidiary of parent-company 
Cincinnati Financial Corporation.  
We also support the independent agencies affiliated with our property casualty operations in their programs 
to sell life insurance. The products offered by our life insurance subsidiary round out and protect accounts 
and improve account persistency. At the same time, our life operation increases diversification of revenue 
and profitability sources for both the agency and our company.  
Our property casualty agencies make up the main distribution system for our life insurance products. To help 
build scale, we also develop life business from other independent life insurance agencies in geographic 
markets underserved through our property casualty agencies. We are careful to solicit business from these 
other agencies in a manner that does not compete with the life insurance marketing and sales efforts of our 
property casualty agencies. Our life insurance operation emphasizes up-to-date products, responsive 
underwriting, high quality service and competitive pricing.  
Other Services to Agencies 
We complement the insurance operations by providing products and services that help attract and retain 
high-quality independent insurance agencies. When we appoint agencies, we look for organizations with 
knowledgeable, professional staffs. In turn, we make an exceptionally strong commitment to assist them in 
keeping their knowledge up to date and educating new people they bring on board as they grow. Numerous 
activities fulfill this commitment at our headquarters, in regional and agency locations and online. 
Except for travel-related expenses to classes held at our headquarters, most programs are offered at no cost 
to our agencies. While that approach may be extraordinary in our industry today, the result is quality service 
for our policyholders and increased success for our independent agencies. 
In addition to broad education and training support, we make available non-insurance financial services. 
CFC Investment Company offers equipment and vehicle leases and loans for independent insurance 
agencies, their commercial clients and other businesses. It also provides commercial real estate loans to 
help agencies operate and expand their businesses. We believe that providing these services enhances 
agency relationships with the company and their clients, increasing loyalty while diversifying the agency’s 
revenues. 
STRATEGIC INITIATIVES  
Management has identified strategies that can position us for long-term success. The board of directors and 
management expect execution of our strategic plan to create significant value for shareholders over time. We 
broadly group these strategies into two areas of focus – improving insurance profitability and driving 
premium growth – correlating with the primary ways we measure our progress toward our long-term 
financial objectives.  
Effective capital management is an important part of creating shareholder value, serving as a foundation to 
support other strategies focused on profitable growth of our insurance business, with the overall objective of 
long-term benefit for shareholders. Our capital management philosophy is intended to preserve and build our 
capital while maintaining appropriate liquidity. A strong capital position provides the capacity to support 
premium growth, and liquidity provides for our investment in the people and infrastructure needed to 
implement our other strategic initiatives. Our strong capital and liquidity also provide financial flexibility for 
shareholder dividends or other capital management actions. 
Our strategies seek to position us to compete successfully in the markets we have targeted while optimizing 
the balance of risk and returns. We believe successful implementation of key initiatives that support our 

Cincinnati Financial Corporation – 2010 10-K – Page 9 

strategies will help us better serve our agent customers, reduce volatility in our financial results and achieve 
our long-term objectives despite shorter-term effects of difficult economic, market or pricing cycles. We 
describe our expectations for the results of these initiatives in Item 7, Executive Summary of the 
Management’s Discussion and Analysis, Page 36. 
Improve Insurance Profitability  
Implementation of the three initiatives below is intended to improve pricing capabilities for our property 
casualty business, improving our ability to manage our business while also enhancing our efficiency. By 
improving pricing capabilities through the use of analytics tools, we can better manage profit margins. By 
improving agency-level planning, we can develop and execute growth and profitability plans that enhance our 
ability to achieve objectives at all levels in the organization. By improving internal processes and further 
developing performance metrics, we can be more efficient and effective. These initiatives also support the 
ability of the agencies that represent us to grow profitably by allowing them to serve clients faster and more 
efficiently manage expenses. The primary initiatives for 2011 to improve insurance profitability are:  
• 

Improve pricing precision using predictive analytics – We continue efforts to expand our pricing 
capabilities by using predictive analytics and expect cumulative benefits of these efforts to improve loss 
ratios over time. Development of additional business data to support accurate underwriting, pricing and 
other business decisions also continues. A phased project that will continue over the next several years 
will deploy a full data management program, including a data warehouse for our property casualty and 
life insurance operations, providing enhanced granularity of pricing data. Specific initiatives that are key 
to improving pricing precision are summarized below. 
o  Commercial lines – In the second half of 2009, we began to use predictive modeling tools that align 
individual insurance policy pricing to risk attributes for our workers’ compensation line of business. 
During fourth-quarter 2010, we completed development of predictive models for our commercial 
auto line of business and also for general liability and commercial property coverages in commercial 
package accounts. We plan in 2011 to integrate these models into our policy processing systems. 
Underwriters using these tools will be able to target profitability and to provide pricing impacts to 
agency personnel. Additional reports to monitor use and results at several levels should also 
contribute to improved pricing.  

• 

• 

o  Personal lines – Prior to 2010, we began to use predictive modeling tools for our homeowner line of 
business, and in late 2010 we began using similar analytics for personal auto. We believe we are 
successfully attracting more of our agents’ preferred business, based on the average quality of our 
book of business. Quality has improved as measured by the mix of business by insurance score. 
During 2011, we will continue to develop the models by calibrating pricing precision to allow us to 
write more business profitably. Further educational support for agency personnel and enhanced 
reporting to monitor results for all users will also be developed. These tools enable us to increase 
the speed of introducing new rates and model attributes, more rapidly adapting to changes in 
market conditions. 

Improve agency-level planning for profitability and growth – Additional use of analytics tools will help us 
better understand business in more detail and communicate additional quantitative and qualitative 
information to agents and associates. Development of models at an agency level to predict profitability, 
along with enhanced reporting of related metrics, should facilitate coordination and consistent decision-
making. During 2011, we expect to enhance our agency planning processes to develop multi-year 
profitability and growth plans. Evaluating agency and state-level plans through models that aggregate 
company-level results will help determine if executing plans formulated at those levels, in aggregate, are 
adequate to reach our broader performance objectives.  
Improve internal processes and further deploy performance metrics – Improving processes supports our 
strategic goals and can reduce internal costs. Use of additional measurements to track progress and 
accountability for results will improve our overall effectiveness. Completion of development for additional 
coverages in our commercial lines policy administration system is expected to facilitate important 
internal process improvement initiatives for 2011. One important initiative aims to develop business 
rules and parameters for personal lines accounts that will allow processing of some business without 
intervention by an underwriter, for risks that meet qualifying underwriting criteria. The objective is to 
streamline processing for our agents and associates, permitting more time for risks that need additional 
service or attention. The initiative also includes developing technology to integrate automated steps into 
the current process plus changes in workflow, including auditing for compliance with eligibility 
requirements. We expect in the future a similar streamlined process will eventually be developed for 
parts of our commercial lines business.  

We measure the overall success of our strategy to improve insurance profitability primarily through 
our GAAP combined ratio for property casualty results, which we believe can be consistently below 
100 percent for any five-year period. 
In addition, we expect these initiatives to contribute to our rank as the No. 1 or No. 2 carrier based on 
premium volume in agencies that have represented us for at least five years. In 2010, we again earned that 
Cincinnati Financial Corporation – 2010 10-K – Page 10 

rank in approximately 75 percent of the agencies that have represented Cincinnati Insurance for more than 
five years, based on 2009 premiums. We are working to increase the percentage of agencies where we 
achieve that rank. 
Drive Premium Growth  
Implementation of the operational initiatives below is intended to further penetrate each market we serve 
through our independent agency network. We expect strategies aimed at specific market opportunities, along 
with service enhancements, to help our agents grow and increase our share of their business. The primary 
initiatives to drive premium growth are: 
•  Gain a larger share of agency business – We will continue to execute on prior year growth initiatives and 

add new initiatives to improve our penetration in each market we serve through our independent 
agencies. Our focus remains on the key components of agent satisfaction based on factors agents tell us 
are most important. 
o 

Innovate our small business strategy – Additional focus on attributes that agencies weigh heavily in 
carrier selection for their clients is a key component of this initiative. Those attributes include 
technology ease of use and integration with agency management systems, flexible billing, product 
breadth and pricing, and service and marketing support for new business. The initiative includes 
refining workflows for the entire policy process and providing additional policyholder services. We 
also are developing and coordinating targeted marketing, including cross-selling opportunities, 
through our Target Markets department. This area focuses on new commercial product 
development, including identification and promotional support for promising classes of business. 
Small business policies are already an important part of our commercial lines property casualty 
insurance segment. Nearly 90 percent of our commercial in-force policies have annual premiums of 
$10,000 or less, accounting in total for approximately one-third of our 2010 commercial lines 
premium volume. Profitably growing our book of small business is expected to provide significant 
growth opportunities for the agencies that represent us while also benefiting the company. Small 
business does not typically trend quite as severely with pricing cycles, producing a more stable block 
of premium. This strategy also is expected to improve profitability due to lower expenses through 
more automation of data gathering and use of predictive analytics. 

o  New agency appointments – We continue to appoint new agencies to develop additional points of 
distribution, focusing on markets where our market share is less than 1 percent while also 
considering economic and catastrophe risk factors. In 2011, we are targeting approximately 
120 appointments of independent agencies, with a significant portion in the five states we entered 
since late 2008. We seek to build a close, long-term relationship with each agency we appoint. We 
carefully evaluate the marketing reach of each new appointment to ensure the territory can support 
both current and new agencies. In counting new agency appointments, we include appointment of 
new agency relationships with The Cincinnati Insurance Companies. For those that we believe will 
produce a meaningful amount of new business premiums, we also count appointments of agencies 
that merge with a Cincinnati agency and new branch offices opened by existing Cincinnati agencies. 
We made 93, 87 and 76 new appointments in 2010, 2009 and 2008, respectively, with 70, 65 and 
52 representing new relationships. One-quarter of the agencies appointed during 2010 were in the 
five states we entered since late 2008: Texas, Colorado, Wyoming, Connecticut and Oregon. The 
contribution of those states to our property casualty premium growth should occur over several years 
as time is required to fully realize the benefits of our agency relationships. We generally earn a 
10 percent share of an agency’s business within 10 years of its appointment. We also help our 
agents grow their business by attracting more clients in their communities through unique 
Cincinnati-style service. 

• 

Improve consumer relationships we undertake on behalf of our agencies – Improved interactions with 
consumers who are clients and prospects of our agents can drive more business to agents and help 
them grow. Through this initiative, we expect to identify the various ways we interact with consumers on 
behalf of our agencies and ensure that we do so in a manner that reinforces the value of the 
independent agent while establishing the value and service of a Cincinnati policy. By understanding and 
monitoring trends that drive consumer purchasing decisions, we can create positive interactions. We 
expect online policyholder services to continue evolving and will continue to work with agencies to meet 
the needs of their clients. 

We measure the overall success of this strategy to drive premium growth primarily through changes in net 
written premiums, which we believe can grow faster than the industry average over any five-year period. On a 
compound annual growth rate basis over the five-year period 2006 through 2010, our property casualty net 
written premiums registered negative 0.7 percent, compared with an estimated negative 0.5 percent for the 
industry. Our premium mix is more heavily weighted in commercial lines, relative to the industry, and 
premium growth rates for the commercial lines segment of the industry have lagged the personal lines 
segment in recent years.

OUR SEGMENTS 
Consolidated financial results primarily reflect the results of our five reporting segments. In the fourth quarter 
of 2010, we revised our reportable operating segments to include excess and surplus lines. This segment 
includes results of The Cincinnati Specialty Underwriters Insurance Company and CSU Producer Resources. 
Historically, the excess and surplus lines results were reflected in Item 7, Other. We began offering excess 
and surplus lines insurance products in 2008. The line continues to grow since inception and separating it 
into a reportable segment allows readers to view this business in a manner similar to how it is managed 
internally when making operating decisions. Prior period data included in this annual report has been 
recasted to represent this new segment. These segments are defined based on financial information we use 
to evaluate performance and to determine the allocation of assets. 
•  Commercial lines property casualty insurance  
•  Personal lines property casualty insurance  
•  Excess and surplus lines property casualty insurance 
• 
• 
We also evaluate results for our consolidated property casualty operations, which is the total of our 
commercial lines, personal lines and excess and surplus lines results.  
Revenues, income before income taxes and identifiable assets for each segment are shown in a table in 
Item 8, Note 18 of the Consolidated Financial Statements, Page 127. Some of that information also is 
discussed in this section of this report, where we explain the business operations of each segment. 
The financial performance of each segment is discussed in the Item 7, Management’s Discussion and 
Analysis of Financial Condition and Results of Operations, which begins on Page 36. 
COMMERCIAL LINES PROPERTY CASUALTY INSURANCE SEGMENT  
The commercial lines property casualty insurance segment contributed net earned premiums of 
$2.154 billion to consolidated total revenues, or 57.1 percent of that total, and reported a gain before 
income taxes of $15 million in 2010. Commercial lines net earned premiums declined 2 percent in 2010, 
5 percent in 2009 and 4 percent in 2008.  
Approximately 95 percent of our commercial lines premiums are written to provide accounts with coverages 
from more than one of our business lines. As a result, we believe that our commercial lines business is best 
measured and evaluated on a segment basis. However, we provide line of business data to summarize 
growth and profitability trends separately for our business lines. The seven commercial business lines are: 
•  Commercial casualty – Provides coverage to businesses against third-party liability from accidents 
occurring on their premises or arising out of their operations, including liability coverage for injuries 
sustained from products sold as well as coverage for professional services, such as dentistry. Specialized 
casualty policies may include liability coverage for employment practices liability (EPLI), which protects 
businesses against claims by employees that their legal rights as employees of the company have been 
violated, and against other acts or failures to act under specified circumstances; and excess insurance 
and umbrella liability, including personal umbrella liability written as an endorsement to commercial 
umbrella coverages. The commercial casualty business line includes liability coverage written on both a 
discounted and nondiscounted basis as part of commercial package policies.  

•  Commercial property – Provides coverage for loss or damage to buildings, inventory and equipment 

caused by covered causes of loss such as fire, wind, hail, water, theft and vandalism, as well as business 
interruption resulting from a covered loss. Commercial property also includes crime insurance, which 
provides coverage for losses such as embezzlement or misappropriation of funds by an employee, 
among others; and inland marine insurance, which provides coverage for a variety of mobile equipment, 
such as contractor’s equipment, builder’s risk, cargo and electronic data processing equipment. Various 
property coverages can be written as stand-alone policies or can be added to a package policy. The 
commercial property business line includes property coverage written on both a nondiscounted and 
discounted basis as part of commercial package policies. 

•  Commercial auto – Protects businesses against liability to others for both bodily injury and property 

damage, medical payments to insureds and occupants of their vehicles, physical damage to an insured’s 
own vehicle from collision and various other perils, and damages caused by uninsured motorists. 
•  Workers’ compensation – Protects employers against specified benefits payable under state or federal 

law for workplace injuries to employees. We write workers’ compensation coverage in all of our active 
states except North Dakota, Ohio and Washington, where coverage is provided solely by the state instead 
of by private insurers.  

•  Specialty packages – Includes coverages for property, liability and business interruption tailored to meet 
the needs of specific industry classes such as artisan contractors, dentists, garage operators, financial 

Cincinnati Financial Corporation – 2010 10-K – Page 12 

institutions, metalworkers, printers, religious institutions, or smaller main street businesses. 
Businessowners policies, which combine property, liability and business interruption coverages for small 
businesses, are included in specialty packages. 

•  Surety and executive risk – This business line includes:  

o  Contract and commercial surety bonds, which guarantee a payment or reimbursement for financial 

losses resulting from dishonesty, failure to perform and other acts.  

o  Fidelity bonds, which cover losses that policyholders incur as a result of fraudulent acts by specified 

individuals or dishonest acts by employees. 

o  Director and officer liability insurance, which covers liability for actual or alleged errors in judgment, 
breaches of duty or other wrongful acts related to activities of for-profit or nonprofit organizations. 
Approximately 70 percent of new policies and almost 40 percent of director and officer new 
business premiums written in 2010 were for nonprofit entities. Our director and officer liability policy 
can optionally include EPLI coverage. 

•  Machinery and equipment – Specialized coverage provides protection for loss or damage to boilers and 
machinery, including production and computer equipment, from sudden and accidental mechanical 
breakdown, steam explosion or artificially generated electrical current. 

Our emphasis is on products that agents can market to small to midsized businesses in their communities. 
Of our 1,544 reporting agency locations, 16 market only our surety and executive risk products and 
11 market only our personal lines products. The remaining 1,517 locations, located in all states in which we 
actively market, offer some or all of our standard market commercial insurance products.  
In 2010, our 10 highest volume commercial lines states generated 64.3 percent of our earned 
premiums compared with 65.3 percent in the prior year as we continued efforts to geographically diversify 
our property casualty risks. Earned premiums in the 10 highest volume states decreased 4 percent in 
2010 and increased 1 percent in the remaining 29 states. The number of reporting agency locations in our 
10 highest volume states increased to 954 in 2010 from 933 in 2009.

For new commercial lines business, case-by-case underwriting and pricing is coordinated by our locally based 
field marketing representatives. Our agents and our field marketing, claims, loss control, premium audit, 
bond and machinery and equipment representatives get to know the people and businesses in their 
communities and can make informed decisions about each risk. These field marketing representatives also 
are responsible for selecting new independent agencies, coordinating field teams of specialized company 
representatives and promoting all of the company’s products within the agencies they serve.  
Commercial lines policy renewals are managed by headquarters underwriters who are assigned to specific 
agencies and consult with local field staff as needed. As part of our team approach, the headquarters 
underwriter also helps oversee agency growth and profitability. They are responsible for formal issuance of all 
new business and renewal policies as well as policy endorsements. Further, the headquarters underwriters 
provide day-to-day customer service to agencies and marketing representatives by offering product training, 

Cincinnati Financial Corporation – 2010 10-K – Page 13 

 
answering underwriting questions, helping to determine underwriting eligibility and assisting with the 
mechanics of premium determination.  
Our emphasis on small to midsized businesses is reflected in the mix of our commercial lines premium 
volume by policy size. Nearly 90 percent of our commercial in-force policies have annual premiums of 
$10,000 or less, accounting in total for approximately one-third of our 2010 commercial lines premium 
volume. The remainder for policies with annual premiums greater than $10,000 includes in-force policies 
with annual premiums greater than $100,000 that account for slightly less than 15 percent of our 
2010 commercial lines premium volume. 
Our commercial lines packages are typically offered on a three-year policy term for most insurance 
coverages, a key competitive advantage. In our experience, multi-year packages appeal to the quality-
conscious insurance buyers who we believe are typical clients of our independent agents. Customized 
insurance programs on a three-year term complement the long-term relationships these policyholders 
typically have with their agents and with the company. By reducing annual administrative efforts, multi-year 
policies lower expenses for our company and for our agents. The commitment we make to policyholders 
encourages long-term relationships and reduces their need to annually re-evaluate their insurance carrier or 
agency. We believe that the advantages of three-year policies in terms of improved policyholder convenience, 
increased account retention and reduced administrative costs outweigh the potential disadvantage of these 
policies, even in periods of rising rates. 
Although we offer three-year policy terms, premiums for some coverages within those policies are adjustable 
at anniversary for the next annual period, and policies may be canceled at any time at the discretion of the 
policyholder. Contract terms often provide that rates for property, general liability, inland marine and crime 
coverages, as well as policy terms and conditions, are fixed for the term of the policy. The general liability 
exposure basis may be audited annually. Commercial auto, workers’ compensation, professional liability and 
most umbrella liability coverages within multi-year packages are rated at each of the policy's annual 
anniversaries for the next one-year period. The annual pricing could incorporate rate changes approved by 
state insurance regulatory authorities between the date the policy was written and its annual anniversary 
date, as well as changes in risk exposures and premium credits or debits relating to loss experience and 
other underwriting judgment factors. We estimate that approximately 75 percent of 2010 commercial 
premiums were subject to annual rating or were written on a one-year policy term.  
Staying abreast of evolving market conditions is a critical function, accomplished in both an informal and 
a formal manner. Informally, our field marketing representatives, underwriters and Target Markets 
department associates are in constant receipt of market intelligence from the agencies with which they work. 
Formally, our commercial lines product management group and field marketing associates conduct periodic 
surveys to obtain competitive intelligence. This market information helps identify the top competitors by line 
of business or specialty program and also identifies our market strengths and weaknesses. The analysis 
encompasses pricing, breadth of coverage and underwriting/eligibility issues.  
In addition to reviewing our competitive position, our product management group and our underwriting audit 
group review compliance with our underwriting standards as well as the pricing adequacy of our commercial 
insurance programs and coverages. Further, our Target Markets department analyzes opportunities 
and develops new products and services, new coverage options and improvements to existing 
insurance products.  
We support our commercial lines operations with a variety of technology tools. e-CLAS® CPP for commercial 
package and auto coverages now has rolled out to all of our appointed agencies in 30 states. It is being 
developed for additional coverages and states that will be deployed over time. Since the initial deployment of 
e-CLAS in late 2009, approximately one-third of our non-workers’ compensation commercial lines policies in 
force at the end of 2010 have been processed through e-CLAS. Due to the three-year policy term for much of 
our commercial lines business, some policies will not be due for renewal processing in e-CLAS until 2012. In 
addition to increasing efficiency for our associates, the system allows our agencies to quote and print 
commercial package policies in their offices, increasing their ease of doing business with us. The e-CLAS 
platform also makes use of our real-time agency interface, CinciBridge®, which allows the automated 
movement of key underwriting data from an agency’s management system to e-CLAS. This reduces agents’ 
data entry tasks and allows seamless quoting, rating and issuance capability.

PERSONAL LINES PROPERTY CASUALTY INSURANCE SEGMENT 
The personal lines property casualty insurance segment contributed net earned premiums of $721 million to 
consolidated total revenues, or 19.1 percent of the total, and reported a loss before income taxes of 
$54 million in 2010. Personal lines net earned premiums grew 5 percent in 2010, after declining less than 
1 percent in 2009 and 3 percent in 2008.  
We prefer to write personal lines coverage in accounts that include both auto and homeowner coverages as 
well as coverages that are part of our other personal business line. As a result, we believe that our personal 
lines business is best measured and evaluated on a segment basis. However, we provide line of business 
data to summarize growth and profitability trends separately for three business lines: 
•  Personal auto – Protects against liability to others for both bodily injury and property damage, medical 

payments to insureds and occupants of their vehicle, physical damage to an insured’s own vehicle from 
collision and various other perils, and damages caused by uninsured motorists. In addition, many states 
require policies to provide first-party personal injury protection, frequently referred to as 
no-fault coverage.  

•  Homeowners – Protects against losses to dwellings and contents from a wide variety of perils, as well as 
liability arising out of personal activities both on and off the covered premises. The company also offers 
coverage for condominium unit owners and renters. 

•  Other personal lines – This includes the variety of other types of insurance products we offer to 

individuals such as dwelling fire, inland marine, personal umbrella liability and watercraft coverages.  

At year-end, we marketed personal lines insurance products through 1,123 or approximately 73 percent of 
our 1,544 reporting agency locations. The 1,123 personal lines agency locations are in 29 of the 39 states in 
which we offer standard market commercial lines insurance and represent nearly 80 percent of the reporting 
agency locations in the 29 states. During 2010, we largely completed an initiative that began in 2008 to 
appoint for personal lines existing agencies marketing only our commercial lines insurance products. We 
continue to evaluate opportunities to expand our marketing of personal lines to other states. Primary factors 
considered in the evaluation of a potential new state include weather-related catastrophe history and the 
legal climate. The number of reporting agency locations in our 10 highest volume states increased 5 percent 
to 749 in 2010 from 711 in 2009. 
In 2010, our 10 highest volume personal lines states generated 82.2 percent of our earned premiums 
compared with 84.1 percent in the prior year. Earned premiums in the 10 highest volume states increased 
3 percent in 2010 while increasing 18 percent in the remaining states, reflecting progress toward our 
long-term objective of geographic diversification through new states for our personal lines operation.

New and renewal personal lines business reflects our risk-specific underwriting philosophy. Each agency 
selects personal lines business primarily from within the geographic territory that it serves, based on the 
agent’s knowledge of the risks in those communities or familiarity with the policyholder. Personal lines 
activities are supported by headquarters associates assigned to individual agencies. At year-end, we had 

Cincinnati Financial Corporation – 2010 10-K – Page 15 

 
seven full-time personal lines marketing representatives who have underwriting authority and visit agencies 
on a regular basis. They focus primarily on key states targeted for growth, reinforcing the advantages of our 
personal lines products and offering training in the use of our processing system. 
Competitive advantages of our personal lines operation include broad coverage forms, flexible underwriting, 
superior claims service, generous credit structure and customizable endorsements for both the personal auto 
and homeowner policies. Our personal lines products are processed through Diamond, our web-based real-
time personal lines policy processing system that supports and allows streamlined processing. Diamond 
incorporates features frequently requested by our agencies such as pre-filling of selected data for improved 
efficiency, easy-to-use screens, local and headquarters policy printing options, data transfer to and from 
popular agency management systems and real-time integration with third-party data such as insurance 
scores, motor vehicle reports and address verification.  
EXCESS AND SURPLUS LINES PROPERTY CASUALTY INSURANCE SEGMENT 
The excess and surplus lines property casualty segment contributed net earned premiums of $49 million to 
consolidated total revenues, or 1.3 percent of the total, and reported a loss before income taxes of $8 million 
in 2010, its third year of operation. Excess and surplus lines net earned premium increased 81 percent in 
2010. Net earned premiums increased 440 percent to $27 million in 2009.  
Our excess and surplus lines policies typically cover business risks with unique characteristics, such as the 
nature of the business or its claim history, that are difficult to profitably insure in the standard commercial 
lines market. Excess and surplus lines insurers have more flexibility in coverage terms and rates compared 
with standard lines companies, generally resulting in policies with higher rates and terms and conditions 
customized for specific risks, including restricted coverage where appropriate. We target small to midsized 
risks, seeking to avoid those we consider exotic in nature. Our average excess and surplus lines policy size is 
approximately $5,000 in annual premiums, and policyholders in many cases also have standard market 
insurance with one of The Cincinnati Insurance Companies. Approximately 80 percent of our 2010 premium 
volume for the excess and surplus lines segment provided commercial casualty coverages and about 
20 percent provided commercial property coverages. Those coverages are described below. 
•  Commercial casualty – Covers businesses for third-party liability from accidents occurring on their 

premises or arising out of their operations, including products and completed operations. The majority of 
these policies have coverage limits of $1 million or less. Miscellaneous errors and omissions and 
professional coverage for liability from actual or alleged errors in judgment, breaches of duty or other 
wrongful acts related to activities of insured businesses is also available, as is excess liability coverage 
that adds another layer of protection to other liability insurance policies. Typical businesses covered 
include contractors, consultants, bars or taverns, and manufacturers. Policies covering liability at special 
events are also available. 

•  Commercial property – Insures loss or damage to buildings, inventory, equipment and business income 

from causes of loss such as fire, wind, hail, water, theft and vandalism. Examples of property we 
commonly insure with excess and surplus lines policies include temporarily vacant buildings, restaurants 
and relatively higher-hazard manufacturing classes. 

At the end of 2010, we marketed excess and surplus lines insurance products in 38 of the 39 states in which 
we offer standard market commercial lines insurance. Offering excess and surplus lines helps agencies 
representing The Cincinnati Insurance Companies meet the insurance needs of their clients when coverage is 
unavailable in the standard market. By providing outstanding service, we can help agencies grow and prosper 
while also profitably growing our property casualty business.  
In 2010, our 10 highest volume excess and surplus lines states generated 65.1 percent of our earned 
premiums compared with 74.2 percent in the prior year.

Agencies representing The Cincinnati Insurance Companies write over $2 billion in annual premiums for 
excess and surplus lines business for all carriers in total that they represent. We estimate that approximately 
half of that premium volume matches the targeted business types and coverages we offer through our 
excess and surplus lines segment. We structured the operations of this segment to meet the needs of these 
agencies and market exclusively through them. 
Agencies have access to The Cincinnati Specialty Underwriters Insurance Company’s product line through 
CSU Producer Resources, the wholly owned insurance brokerage subsidiary of parent-company Cincinnati 
Financial Corporation. CSU Producer Resources has binding authority on all classes of business written 
through The Cincinnati Specialty Underwriters Insurance Company and maintains appropriate agent and 
surplus lines licenses to process non-admitted business.  
We seek to earn a share of each agency’s best excess and surplus lines accounts by offering several unique 
benefits. Agency producers have direct access through CSU Producer Resources to a group of our 
underwriters who focus exclusively on excess and surplus lines business. Those underwriters can tap into 
agencies’ broader Cincinnati relationships to bring their policyholders services such as experienced and 
responsive loss control and claims handling. CSU Producer Resources gives extra support to our producers by 
remitting surplus lines taxes and stamping fees and retaining admitted market diligent search affidavits, 
where required. Agencies marketing through CSU Producer Resources generally receive a higher commission 
because use of our internal brokerage subsidiary eliminates some of the intermediary costs. This business is 
also factored in their profit-sharing agreement with The Cincinnati Insurance Companies. 
We use a web-based excess and surplus lines policy administration system to quote, bind, issue and deliver 
policies electronically to agents. This system also provides integration to existing document management and 
data management systems, allowing for real-time processing of policies and billing. It provides a specimen 
policy detailing coverages when a policy is quoted and delivers electronic copies of policies to producers 
within minutes of underwriting approval and policy issue. In 2010, more than 95 percent of policies were 
issued within 24 hours of a request to bind a policy. Also in 2010, we received the Celent Model Insurer 
Award, recognizing our efficient use of technology. We successfully leveraged our policy administration 
system to quickly enter a new market, developing our miscellaneous errors and omissions product in only 
three months and then issuing the first 50 policies within two weeks. 
LIFE INSURANCE SEGMENT  
The life insurance segment contributed $158 million of net earned premiums, representing 4.2 percent of 
consolidated total revenues, and $7 million of income before income taxes in 2010. Life insurance segment 
profitability is discussed in detail in Item 7, Life Insurance Results of Operations, Page 73. Life insurance net 
earned premiums grew 10 percent in 2010, 13 percent in 2009 and less than 1 percent in 2008. 
The Cincinnati Life Insurance Company supports our agency-centered business model. Cincinnati Life helps 
meet the needs of our agencies, including increasing and diversifying agency revenues. We primarily focus on 
life products that produce revenue growth through a steady stream of premium payments. By diversifying 

Cincinnati Financial Corporation – 2010 10-K – Page 17 

 
revenue and profitability for both the agency and our company, this strategy enhances the already strong 
relationship built by the combination of the property casualty and life companies. 
Life Insurance Business Lines 
Four lines of business – term insurance, universal life insurance, worksite products and whole life insurance 
– account for approximately 96.9 percent of the life insurance segment’s revenues: 
• 

Term insurance – policies under which a death benefit is payable only if the insured dies during a 
specific period of time. For policies without a return of premium provision, no benefit is payable if the 
insured person survives to the end of the term. For policies inforce with a return of premium provision, 
a benefit equal to the sum of all paid base premiums is payable if the insured person survives to the end 
of the term. Premiums are fixed and they must be paid as scheduled. The policies are fully underwritten. 

•  Universal life insurance – long-duration life insurance policies. Contract premiums are neither fixed nor 
guaranteed; however, the contract does specify a minimum interest crediting rate and a maximum cost 
of insurance charge and expense charge. Premiums are not fixed and may be varied by the contract 
owner. The cash values, available as a loan collateralized by the cash surrender value, are not 
guaranteed and depend on the amount and timing of actual premium payments and the amount of 
actual contract assessments. The policies are fully underwritten. Contracts with death benefit 
guarantees are available for individuals as well as for two lives on contracts called survivor universal life. 

•  Worksite products – term insurance, return of premium term insurance, whole life insurance, universal 

life and disability insurance offered to employees through their employer. Premiums are collected by the 
employer using payroll deduction. Policies are issued using a simplified underwriting approach and on a 
guaranteed issue basis. Worksite insurance products provide our property casualty agency force with 
excellent cross-serving opportunities for both commercial and personal accounts. Agents report that 
offering worksite marketing to employees of their commercial accounts provides a benefit to the 
employees at no cost to the employer. Worksite marketing also connects agents with new customers who 
may not have previously benefited from receiving the services of a professional independent 
insurance agent. 

•  Whole life insurance – policies that provide life insurance for the entire lifetime of the insured. The death 

benefit is guaranteed never to decrease and premiums are guaranteed never to increase. 
While premiums are fixed, they must be paid as scheduled. These policies provide guaranteed 
cash values that are available as loans collateralized by the cash surrender value. The policies are 
fully underwritten. 

In addition, Cincinnati Life markets:  
•  Disability income insurance that provides monthly benefits to offset the loss of income when the insured 

person is unable to work due to accident or illness.  

•  Deferred annuities that provide regular income payments that commence after the end of a specified 
period or when the annuitant attains a specified age. During the deferral period, any payments made 
under the contract accumulate at the crediting rate declared by the company but not less than a 
contract-specified guaranteed minimum interest rate. A deferred annuity may be surrendered during the 
deferral period for a cash value equal to the accumulated payments plus interest less the surrender 
charge, if any. 

• 

Immediate annuities that provide some combination of regular income and lump sum payments in 
exchange for a single premium. 

Life Insurance Distribution 
Cincinnati Life seeks to become the life insurance carrier of choice for the independent agencies that work 
with our property casualty operations. We emphasize up-to-date products, responsive underwriting and high 
quality service as well as competitive commissions. At year-end 2010, almost 90 percent of our 
1,544 property casualty reporting agency locations offered Cincinnati Life’s products to their clients. We also 
develop life business from approximately 500 other independent life insurance agencies. We are careful to 
solicit business from these other agencies in a manner that does not conflict with or compete with the 
marketing and sales efforts of our property casualty agencies. 
When marketing through our property casualty agencies, we have specific competitive advantages: 
•  Because our property casualty operations are held in high regard, property casualty agency management 

is predisposed to consider selling our life products.  

•  Marketing efforts for both our property casualty and life insurance businesses are directed by our field 

marketing department, which assures consistency of communication and operations. Life field marketing 
representatives are available to meet face-to-face with agency personnel and their clients as well.  
•  Our life headquarters underwriters and other associates are available to the agents and field team to 

assist in the placement of business. Fewer and fewer of our competitors provide direct, personal support 
between the agent and the insurance carrier. 

Cincinnati Financial Corporation – 2010 10-K – Page 18 

We continue to emphasize the cross-serving opportunities of our life insurance, including term and worksite 
products, for the property casualty agency’s personal and commercial accounts. In both the property casualty 
and independent life agency distribution systems, we enjoy the advantages of offering competitive, up-to-
date products, providing close personal attention in combination with financial strength and stability. 
•  We primarily offer products addressing the needs of businesses with key person and buy-sell coverages. 
We offer personal and commercial clients of our agencies quality, personal life insurance coverage.  

• 

Term insurance is our largest life insurance product line. We continue to introduce new term products 
with features our agents indicate are important, such as a return of premium benefit, and we have 
restructured our underwriting classifications to better meet the needs of their clients. 

Because of our strong capital position, we can offer a competitive product portfolio including guaranteed 
products, giving our agents a marketing edge. Our life insurance company maintains strong insurer financial 
strength ratings: A.M. Best – A (Excellent), Fitch – A+ (Strong) and Standard & Poor’s – A (Strong), as 
discussed in Financial Strength, Page 5. Our life insurance company has chosen not to establish a 
Moody’s rating. 
INVESTMENT SEGMENT  
Revenues of the investment segment are primarily from net investment income and from realized investment 
gains and losses from investment portfolios managed for the holding company and each of the operating 
subsidiaries.  
Our investment department operates under guidelines set forth in our investment policy statement along with 
oversight of the investment committee of our board of directors. These guidelines set parameters for risk 
tolerances governing, among other items, the allocation of the portfolio as well as security and sector 
concentrations. These parameters are part of an integrated corporate risk management program.  
The fair value of our investment portfolio was $11.424 billion and $10.562 billion at year-end 2010 and 
2009, respectively. The overall portfolio remained in an unrealized gain position as strong returns in the 
equity and corporate bond markets more than offset a decline in the municipal bond market.  
The cash we generate from insurance operations historically has been invested in three broad categories 
of investments:  
• 

Fixed-maturity investments – Includes taxable and tax-exempt bonds and redeemable preferred stocks. 
During 2010 and 2009, purchases and market value gains served to more than offset sales and calls.  
•  Equity investments – Includes common and nonredeemable preferred stocks. During 2010, purchases 
and fair value gains more than offset sales. During 2009, sales slightly offset fair value appreciation of 
equity securities. 

•  Short-term investments – Primarily commercial paper.

We actively determine the portion of new cash flow to be invested in fixed-maturity and equity securities at 
the parent and insurance subsidiary levels. During 2010, approximately one-quarter of new cash flow was 
invested in equity securities, consistent with our long-term average. We consider internal measures, as well 
as insurance department regulations and rating agency guidance. We monitor a variety of metrics, including 
after-tax yields, the ratio of investments in common stocks to statutory surplus for the property casualty and 
life insurance operations, and the parent company’s ratio of investment assets to total assets. 
At year-end 2010, less than 1 percent of the value of our investment portfolio was made up of securities that 
do not actively trade on a public market and require management’s judgment to develop pricing or valuation 
techniques (Level 3 assets). We generally obtain at least two outside valuations for these assets and 
generally use the more conservative estimate. These investments include private placements, small issues 
and various thinly traded securities. See Item 7, Fair Value Measurements, Page 46, and Item 8, Note 3 of 
the Consolidated Financial Statements Page 114, for additional discussion of our valuation techniques.  
In addition to securities held in our investment portfolio, at year-end 2010, other invested assets included 
$40 million of life policy loans, $28 million of venture capital fund investments, $5 million of investment in 
real estate and $11 million of other invested assets. 
Fixed-maturity and Short-term Investments 
By maintaining a well diversified fixed-maturity portfolio, we attempt to manage overall interest rate, 
reinvestment, credit and liquidity risk. We pursue a buy-and-hold strategy and do not attempt to make large-

Cincinnati Financial Corporation – 2010 10-K – Page 19 

 
scale changes to the portfolio in anticipation of rate movements. By investing new money on a regular basis 
and analyzing risk-adjusted after-tax yields, we work to achieve a laddering effect to our portfolio that may 
mitigate some of the effects of adverse interest rate movements.  
Fixed-maturity and Short-term Portfolio Ratings 
As of year-end 2010, this portfolio’s fair value was 106.3 percent of book value, up from last year due to both 
a decline in the general level of treasury rates and a continued tightening of credit spreads.  
The portfolio grew in 2010 due to a large volume of purchases. These purchases were most concentrated in 
the investment grade corporate bond market. Although the average rating of our bond portfolio remained 
unchanged, the number of bonds rated Aaa/AAA decreased and the number of bonds rated Aa/AA increased. 
The rating distribution change was driven by net redemptions of U.S. agency (government-sponsored 
enterprises) bonds due to call activity and an increase in purchases of Build America Bonds. The majority of 
our non-rated securities are tax-exempt municipal bonds from smaller municipalities that chose not to pursue 
a credit rating. Credit ratings at year-end 2010 for the fixed-maturity and short-term portfolios were:

While our strategy typically is to buy and hold fixed-maturity investments to maturity, we monitor credit 
profiles and fair value movements when determining holding periods for individual securities. With the 
exception of U.S. agency issues, no individual issuer's securities accounted for more than 1.1 percent of the 
taxable fixed-maturity portfolio at year-end 2010. Investment grade corporate bonds had an average rating of 
Baa1 by Moody’s or BBB+ by Standard & Poor’s and represented 84.8 percent of the taxable fixed maturity 
portfolio’s fair value at year end 2010, compared with 80.9 percent in 2009. 
The investment-grade corporate bond portfolio is most heavily concentrated in the financial-related sectors, 
including banking, financial services and insurance. The financial sectors represented 28.9 percent of fair 
value of this portfolio at year-end 2010, compared with 25.3 percent, at year-end 2009. Although the 
financial-related sectors make up our largest group of investment-grade corporate bonds, we believe our 
concentration is below the average for the corporate bond market as a whole. Energy was the only other

sector that exceeded 10 percent of our investment-grade corporate bond portfolio, at 10.0 percent of fair 
value at year-end 2010.  
Most of the $293 million of securities issued by states, municipalities and political subdivisions securities 
included in our taxable fixed maturity portfolio at the end of 2010 were Build America Bonds. 
Tax-exempt Fixed Maturities 
Our tax-exempt fixed maturity portfolio’s fair value was $2.850 billion at December 31, 2010. We traditionally 
have purchased municipal bonds focusing on general obligation and essential services, such as sewer, water 
or others. The portfolio is well diversified among approximately 1,000 municipal bond issuers. No single 
municipal issuer accounted for more than 0.7 percent of the tax-exempt fixed maturity portfolio at year-end 
2010. Municipal bond holdings in our larger states were:

At year-end 2010, our tax-exempt fixed maturity portfolio, with a fair value of $2.850 billion, had an average 
rating of Aa2/AA. Almost 80 percent or $2.245 billion of the portfolio is insured, and approximately 
93 percent of the insured portion carried an underlying rating of at least A3 or A- by Moody’s or Standard & 
Poor’s at year end. We strongly prefer general obligation or essential services bonds, which we believe 
provide a superior risk profile.  
Equity Investments 
After covering both our intermediate and long-range insurance obligations with fixed-maturity investments, 
we historically used available cash flow to invest in equity securities. Investment in equity securities has 
played an important role in achieving our portfolio objectives and has contributed to portfolio appreciation. 
We remain committed to our long-term equity focus, which we believe is key to our company’s long-term 
growth and stability. 
Common Stocks 
Our cash allocation for common stock purchases is implemented only after we ensure that insurance 
reserves are adequately covered by our fixed-maturity investments. We believe our strategy of primarily 
investing in a diversified selection of larger capitalization, high quality, dividend-increasing companies 
generally results in reduced volatility relative to the broader equity markets.

Preferred Stocks 
We evaluate preferred stocks in a manner similar to our evaluation of fixed-maturity investments, seeking 
attractive relative yields. We generally focus on investment-grade preferred stocks issued by companies with 
strong histories of paying common dividends, providing us with another layer of protection. When possible, 
we seek out preferred stocks that offer a dividend received deduction for income tax purposes. Events in the 
fall of 2008 and into early 2009 led us to re-evaluate the riskiness of all preferred securities, particularly 
those of banking institutions. As a result, during 2009 we downsized this portfolio by $82 million of fair value 
to $93 million. We made no additional purchases or sales for this portfolio during 2010. 
Short-Term Investments 
At December 31, 2010, we had no short-term investments, compared with $6 million at year-end 2009. Our 
short-term investments consisted primarily of commercial paper, demand notes or bonds purchased within 
one year of maturity.  
Additional information about the composition of investments is included in Item 8, Note 2 of the 
Consolidated Financial Statements, Page 111. A detailed listing of our portfolio is updated on our website, 
www.cinfin.com/investors, each quarter when we report our quarterly financial results. 
OTHER 
We report as Other the non-investment operations of the parent company and its subsidiary CFC Investment 
Company. This subsidiary offers commercial leasing and financing services to our agencies, their clients and 
other customers. As of year-end 2010, CFC Investment Company had 2,227 accounts and $73 million in 
receivables, compared with 2,286 accounts and $75 million in receivables at year-end 2009. 
REGULATION 
The business of insurance primarily is regulated by state law. All of our insurance company subsidiaries are 
domiciled in the state of Ohio, except The Cincinnati Specialty Underwriters, which is domiciled in the state of 
Delaware. Each insurance subsidiary is governed by the insurance laws and regulations in its respective state 
of domicile. We also are subject to state regulatory authorities of all states in which we write insurance. The 
state laws and regulations that have the most significant effect on our insurance operations and financial 
reporting are discussed below.  
• 

Insurance Holding Company Regulation – We are regulated as an insurance holding company system in 
the respective states of domicile of our standard market property casualty company subsidiary and its 
surplus lines and life insurance subsidiaries. These regulations require that we annually furnish financial 
and other information about the operations of the individual companies within the holding company 
system. All transactions within a holding company affecting insurers must be fair and equitable. Notice to 
the state insurance commissioner is required prior to the consummation of transactions affecting the 
ownership or control of an insurer and prior to certain material transactions between an insurer and any 
person or entity in its holding company group. In addition, some of those transactions cannot be 
consummated without the commissioner’s prior approval. 

Cincinnati Financial Corporation – 2010 10-K – Page 22 

 
•  Subsidiary Dividends – The Cincinnati Insurance Company is 100 percent owned by Cincinnati Financial 
Corporation. The dividend-paying capacity of The Cincinnati Insurance Company and its 100 percent 
owned subsidiaries is regulated by the laws of the applicable state of domicile. Under these laws, our 
insurance subsidiaries must provide a 10-day advance informational notice to the insurance 
commissioner for the domiciliary state prior to payment of any dividend or distribution to its 
shareholders. Generally, the most our insurance subsidiary can pay without prior regulatory approval is 
the greater of 10 percent of policyholder surplus or 100 percent of statutory net income for the prior 
calendar year. Dividends exceeding these limitations may be paid only with approval of the insurance 
department of the domiciliary state. 
The insurance company subsidiaries must give 30 days notice to and obtain prior approval from the 
state insurance commissioner before the payment of an extraordinary dividend as defined by the 
state’s insurance code. You can find information about the dividends paid by our insurance subsidiary in 
2010 in Item 8, Note 9 of the Consolidated Financial Statements, Page 118. 

• 

Insurance Operations – All of our insurance subsidiaries are subject to licensing and supervision by 
departments of insurance in the states in which they do business. The nature and extent of such 
regulations vary, but generally have their source in statutes that delegate regulatory, supervisory and 
administrative powers to state insurance departments. Such regulations, supervision and administration 
of the insurance subsidiaries include, among others, the standards of solvency that must be met and 
maintained; the licensing of insurers and their agents and brokers; the nature and limitations on 
investments; deposits of securities for the benefit of policyholders; regulation of standard market policy 
forms and premium rates; policy cancellations and non-renewals; periodic examination of the affairs of 
insurance companies; annual and other reports required to be filed on the financial condition of insurers 
or for other purposes; requirements regarding reserves for unearned premiums, losses and other 
matters; the nature of and limitations on dividends to policyholders and shareholders; the nature and 
extent of required participation in insurance guaranty funds; the involuntary assumption of hard-to-place 
or high-risk insurance business, primarily workers’ compensation insurance; and the collection, 
remittance and reporting of certain taxes and fees. In 2010, our primary insurance regulators adopted 
the Model Audit Rule for annual statutory financial reporting. This regulation closely mirrors the 
Sarbanes-Oxley Act on matters such as auditor independence, corporate governance and internal 
controls over financial reporting. The regulation permits the audit committee of Cincinnati Financial 
Corporation’s board of directors to also serve as the audit committee of each of our insurance 
subsidiaries for purposes of this regulation. 
The legislative and regulatory climate in Florida continues to create uncertainty for the insurance 
industry. In February 2007, we adopted a marketing stance of continuing to service existing accounts 
while writing no new business relationships in Florida. This remained our stance through 2009, except in 
the lines of directors and officers, surety, machinery and equipment and life insurance, which we 
resumed writing in June 2007, subject to existing guidelines. In 2009, we cautiously resumed writing 
additional commercial lines new business while working to more actively manage the associated 
catastrophe risk, carefully underwriting new commercial submissions and non-renewing commercial and 
personal lines policies that present the most risk of loss because of their age, construction and 
geographic characteristics. In 2010, our property casualty net written premiums from Florida agencies 
were 1.7 percent of net written premiums, compared with 1.9 percent in 2009.  
On August 24, 2007, the company received administrative subpoenas from the Florida Office of 
Insurance Regulation seeking documents and testimony concerning insurance for residential risks 
located in Florida and communications with reinsurers, risk modeling companies, rating agencies and 
insurance trade associations. We produced documents to respond to the subpoenas. The Office of 
Insurance Regulation canceled and has not rescheduled the hearing noticed in the subpoena for 
October 18, 2007. Although inactive, these subpoenas remain outstanding as of December 31, 2010. 
We continue to assess the changing insurance environment in Florida and hope to resume writing our 
complete portfolio of insurance products in the state as the market stabilizes. 

• 

Insurance Guaranty Associations – Each state has insurance guaranty association laws under which the 
associations may assess life and property casualty insurers doing business in the state for certain 
obligations of insolvent insurance companies to policyholders and claimants. Typically, states assess 
each member insurer in an amount related to the insurer’s proportionate share of business written by all 
member insurers in the state. Our insurance companies received a savings of less than $3 million from 
guaranty associations in 2010 and a savings of less than $2 million in 2009. We cannot predict the 
amount and timing of any future assessments or refunds on our insurance subsidiaries under 
these laws. 

•  Shared Market and Joint Underwriting Plans – State insurance regulation requires insurers to participate 
in assigned risk plans, reinsurance facilities and joint underwriting associations, which are mechanisms 
that generally provide applicants with various basic insurance coverages when they are not available in 
voluntary markets. Such mechanisms are most commonly instituted for automobile and workers’ 

Cincinnati Financial Corporation – 2010 10-K – Page 23 

compensation insurance, but many states also mandate participation in FAIR Plans or Windstorm Plans, 
which provide basic property coverages. Participation is based upon the amount of a company’s 
voluntary market share in a particular state for the classes of insurance involved. Underwriting results 
related to these organizations could be adverse to our company. 

•  Statutory Accounting – For public reporting, insurance companies prepare financial statements in 

accordance with GAAP. However, certain data also must be calculated according to statutory accounting 
rules as defined in the NAIC’s Accounting Practices and Procedures Manual. While not a substitute for 
any GAAP measure of performance, statutory data frequently is used by industry analysts and other 
recognized reporting sources to facilitate comparisons of the performance of insurance companies. 

• 

Insurance Reserves – State insurance laws require that property casualty and life insurers annually 
analyze the adequacy of reserves. Our appointed actuaries must submit an opinion that reserves are 
adequate for policy claims-paying obligations and related expenses. 

•  Risk-Based Capital Requirements – The NAIC’s risk-based capital (RBC) requirements for property 

casualty and life insurers serve as an early warning tool for the NAIC and state regulators to identify 
companies that may be undercapitalized and may merit further regulatory action. The NAIC has a 
standard formula for annually assessing RBC. The formula for calculating RBC for property casualty 
companies takes into account asset and credit risks but places more emphasis on underwriting factors 
for reserving and pricing. The formula for calculating RBC for life insurance companies takes into account 
factors relating to insurance, business, asset and interest rate risks.  

Although the federal government and its regulatory agencies generally do not directly regulate the business 
of insurance, federal legislation and administrative rules adopted to implement them do affect our business. 
Privacy laws, such as the Gramm-Leach-Bliley Act, the Fair Credit Reporting Act and the Health Insurance 
Portability and Accounting Act (HIPAA) are the federal laws that most affect our day-to-day operations. These 
apply to us because we gather and use personal non-public information to underwrite insurance and process 
claims. We also are subject to other federal laws, such as the Terrorism Risk Insurance Act (TRIA), anti-money 
laundering statute (AML), and the rules and regulations of the Office of Foreign Assets Control (OFAC). 
Title V of the Dodd-Frank Wall Street Reform and Consumer Protection Act of 2010 (Dodd-Frank) created the 
Federal Insurance Office to monitor the insurance industry and gather information to identify issues or gaps 
in the regulation of insurers that could contribute to a systemic crisis in the insurance industry of the United 
States financial system, and to recommend to the Financial Stability Oversight counsel that it designate an 
insurer as a systemically significant entity requiring additional supervision by the Federal Reserve Board. 
Although rules have not yet been proposed or implemented to govern the determination that a non-bank 
financial company, such as an insurance company, presents systemic risk, we do not expect such rules, 
when adopted, to result in federal oversight of our operations as a systemically significant entity. 
We do not expect to have any material effects on our expenditures, earnings or competitive position as a 
result of compliance with any federal, state, or local provisions enacted or adopted relating to the protection 
of the environment. We currently do not have any material estimated capital expenditures for environmental 
control facilities. 
Item 1A.  Risk Factors 
Our business involves various risks and uncertainties that may affect achievement of our business 
objectives. Many of the risks could have ramifications across our organization. For example, while risks 
related to setting insurance rates and establishing and adjusting loss reserves are insurance activities, errors 
in these areas could have an impact on our investment activities, growth and overall results.  
The following discussion should be viewed as a starting point for understanding the significant risks we face. 
It is not a definitive summary of their potential impacts or of our strategies to manage and control the risks. 
Please see Item 7, Management’s Discussion and Analysis of Financial Condition and Results of Operations, 
Page 36, for a discussion of those strategies.  
If any risks or uncertainties discussed here develop into actual events, they could have a material adverse 
effect on our business, financial condition or results of operations. In that case, the market price of our 
common stock could decline materially.  
Readers should carefully consider this information together with the other information we have provided in 
this report and in other reports and materials we file periodically with the Securities and Exchange 
Commission as well as news releases and other information we disseminate publicly.  
We rely exclusively on independent insurance agents to distribute our products. 
We market our products through independent, non-exclusive insurance agents. These agents are not 
obligated to promote our products and can and do sell our competitors’ products. We must offer insurance 
products that meet the needs of these agencies and their clients. We need to maintain good relationships 
with the agencies that market our products. If we do not, these agencies may market our competitors’ 

Cincinnati Financial Corporation – 2010 10-K – Page 24 

products instead of ours, which may lead to us having a less desirable mix of business and could affect our 
results of operations.  
Certain events or conditions could diminish our agents’ desire to produce business for us and the 
competitive advantage that our independent agencies enjoy, including:  
•  Downgrade of the financial strength ratings of our insurance subsidiaries. We believe our strong insurer 

financial strength ratings, in particular the A+ (Superior) rating from A.M. Best for our standard market 
property casualty insurance subsidiaries, are an important competitive advantage. Ratings agencies 
could change or expand their requirements. If our property casualty ratings were to be downgraded, our 
agents might find it more difficult to market our products or might choose to emphasize the products of 
other carriers. See Item 1, Our Business and Our Strategy, Page 3, for additional discussion of our 
financial strength ratings. 

•  Concerns that doing business with us is difficult or not profitable, perceptions that our level of service is 
no longer a distinguishing characteristic in the marketplace, perceptions that our products do not meet 
the needs of our agents’ clients or perceptions that our business practices are not compatible with 
agents’ business models.  

•  Delays in the development, implementation, performance and benefits of technology projects and 

enhancements or independent agent perceptions that our technology solutions are inadequate to match 
their needs.  

A reduction in the number of independent agencies marketing our products, the failure of agencies to 
successfully market our products or pay their accounts due to us, changes in the strategy or operations of 
agencies or the choice of agencies to reduce their writings of our products could affect our results of 
operations if we were unable to replace them with agencies that produce adequate and profitable premiums.  
Further, policyholders may choose a competitor’s product rather than our own because of real or perceived 
differences in price, terms and conditions, coverage or service. If the quality of the independent agencies 
with which we do business were to decline, that also might cause policyholders to purchase their insurance 
through different agencies or channels. Consumers, especially in the personal insurance segments, may 
increasingly choose to purchase insurance from distribution channels other than independent insurance 
agents, such as direct marketers.  
We could experience an unusually high level of losses due to catastrophic, terrorism or 
pandemic events or risk concentrations.  
In the normal course of our business, we provide coverage against perils for which estimates of losses are 
highly uncertain, in particular catastrophic and terrorism events. Catastrophes can be caused by a number of 
events, including hurricanes, tornadoes, windstorms, earthquakes, hailstorms, explosions, severe winter 
weather and fires. Due to the nature of these events, we are unable to predict precisely the frequency or 
potential cost of catastrophe occurrences. Various scientists and other experts believe that changing climate 
conditions have added to the unpredictability, frequency and severity of such natural disasters in certain 
parts of the world and have created additional uncertainty as to future trends and exposures. We cannot 
predict the impact that changing climate conditions may have on our results of operations nor can we predict 
how any legal, regulatory or social responses to concerns about climate change may impact our business. 
The extent of losses from a catastrophe is a function of both the total amount of insured exposure in the area 
affected by the event and the severity of the event. Our ability to appropriately manage catastrophe risk 
depends partially on catastrophe models, the accuracy of which may be affected by inaccurate or 
incomplete data, the uncertainty of the frequency and severity of future events and the uncertain impact of 
climate change.  
The geographic regions in which we market insurance are exposed to numerous natural catastrophes, 
such as: 
•  Hurricanes in the gulf, eastern and southeastern coastal regions. 
•  Earthquakes in the New Madrid fault zone, which lies within the central Mississippi valley, extending from 
northeast Arkansas through southeast Missouri, western Tennessee and western Kentucky to southern 
Illinois, southern Indiana and parts of Ohio.  

Tornado, wind and hail in the Midwest, South, Southeast, Southwest and the mid-Atlantic. 

• 
The occurrence of terrorist attacks in the geographic areas we serve could result in substantially higher 
claims under our insurance policies than we have anticipated. While we do insure terrorism risk in all areas 
we serve, we have identified our major terrorism exposure as general commercial risks in the metropolitan 
Chicago area, small co-op utilities, small shopping malls and small colleges throughout our 39 active states 
and, because of the number of associates located there, our Fairfield headquarters. Additionally, our life 
insurance subsidiary could be adversely affected in the event of a terrorist event or an epidemic such as the 
avian or swine flu, particularly if the epidemic were to affect a broad range of the population beyond just the 
very young or the very old. Our associate health plan is self-funded and could similarly be affected.  

Cincinnati Financial Corporation – 2010 10-K – Page 25 

Our results of operations would be adversely affected if the level of losses we experience over a period of 
time were to exceed our actuarially determined expectations. In addition, our financial condition may be 
adversely affected if we were required to sell securities prior to maturity or at unfavorable prices to pay an 
unusually high level of loss and loss expenses. Securities pricing might be even less favorable if a number of 
insurance or other companies and other investors needed to sell securities during a short period of time 
because of unusually high losses from catastrophic events. 
Our geographic concentration ties our performance to business, economic, environmental and regulatory 
conditions in certain states. We market our standard market property casualty insurance products in 
39 states, but our business is concentrated in the Midwest and Southeast. We also have exposure in states 
where we do not actively market insurance when clients of our independent agencies have businesses or 
properties in multiple states. 
The Cincinnati Insurance Company also participates in three assumed reinsurance treaties with two 
reinsurers that spread the risk of very high catastrophe losses among many insurers. In 2010, the largest 
treaty had exposure of up to $7 million of assumed losses in three layers, from $1.0 billion to $1.7 billion, 
from a single event under an assumed reinsurance treaty for Munich Re Group. Amounts related to the other 
two treaties are immaterial. 
In the event of a severe catastrophic event or terrorist attack elsewhere in the world, our insurance losses 
may be immaterial. However, the companies in which we invest might be severely affected, which could 
affect our financial condition and results of operations. Our reinsurers might experience significant losses, 
potentially jeopardizing their ability to pay losses we cede to them. We also may be exposed to state 
guaranty fund assessments if other carriers in a state cannot meet their obligations to policyholders. 
A catastrophe or epidemic event also could affect our operations by damaging our headquarters facility, 
injuring associates and visitors at our Fairfield, Ohio, headquarters or disrupting our associates’ ability to 
perform their assigned tasks. 
Our ability to achieve our performance objectives could be affected by changes in the 
financial, credit and capital markets or the general economy. 
We invest premiums received from policyholders and other available cash to generate investment income 
and capital appreciation, while also maintaining sufficient liquidity to pay covered claims and operating 
expenses, service our debt obligations and pay dividends.  
Investment income is an important component of our revenues and net income. The ability to increase 
investment income and generate longer-term growth in book value is affected by factors beyond our control, 
such as inflation; economic growth; interest rates; world political conditions; changes in laws and regulations; 
terrorism attacks or threats; adverse events affecting other companies in our industry or the industries in 
which we invest; market events leading to credit constriction; and other widespread unpredictable events. 
These events may adversely affect the economy generally and could cause our investment income or the 
value of securities we own to decrease. A significant decline in our investment income could have an adverse 
effect on our net income, and thereby on our shareholders’ equity and our policyholders’ surplus. For 
example, a significant increase in the general level of interest rates could lead to falling bond values. For 
more detailed discussion of risks associated with our investments, please refer to Item 7A, Quantitative and 
Qualitative Disclosures About Market Risk, Page 93. 
We issue life contracts with guaranteed minimum returns, referred to as bank-owned life insurance contracts 
(BOLIs). BOLI investment assets must meet certain criteria established by the regulatory authorities in the 
jurisdiction for which the group contract holder is subject. Therefore, sales of investments may be mandated 
to maintain compliance with these regulations, possibly requiring gains or losses to be recorded. We could 
experience losses if the assets in the accounts were less than liabilities at the time of maturity or 
termination. We discuss other risks associated with our separate account BOLIs in Item 7, Critical Accounting 
Estimates, Separate Accounts, Page 47. 
Our investment performance also could suffer because of the types of investments, industry groups and/or 
individual securities in which we choose to invest. Market value changes related to these choices could 
cause a material change in our financial condition or results of operations.  
At year-end 2010, common stock holdings made up 25.5 percent of our invested assets. Adverse news or 
events affecting the global or U.S. economy or the equity markets could affect our net income, book value 
and overall results, as well as our ability to pay our common stock dividend. See Item 7, Investments Results 
of Operations, Page 75, and Item 7A, Quantitative and Qualitative Disclosures About Market Risk, Page 93, 
for discussion of our investment activities.  
Deterioration in the banking sector or in banks with which we have relationships could affect our results of 
operations. Our ability to maintain or obtain short-term lines of credit could be affected if the banks from 
which we obtain these lines are purchased, fail or are otherwise negatively affected. We may lose premium if 
a bank that owns appointed agencies were to change its strategies. We could experience increased losses in 
our director and officer liability line of business if claims were made against insured financial institutions. 

Cincinnati Financial Corporation – 2010 10-K – Page 26 

Deteriorating credit and market conditions could also impair our ability to access credit markets and could 
affect existing or future lending arrangements. 
Our overall results could be affected if a significant portion of our commercial lines policyholders, including 
those purchasing surety bonds, are adversely affected by marked or prolonged economic downturns and 
events such as a downturn in construction and related sectors, tightening credit markets and higher fuel 
costs. Such events could make it more difficult for policyholders to finance new projects, complete projects or 
expand their businesses, leading to lower premiums from reduced payrolls and sales and lower purchases of 
equipment and vehicles. These events could also cause claims, including surety claims, to increase due to a 
policyholder’s inability to secure necessary financing to complete projects or to collect on underlying lines of 
credit in the claims process. Such economic downturns and events could have a greater impact in the 
construction sector where we have a concentration of risks and in geographic areas that are hardest hit by 
economic downturns.  
Deteriorating economic conditions could also increase the degree of credit risk associated with amounts due 
from independent agents who collect premiums for payment to us and could hamper our ability to recover 
amounts due from reinsurers.  
Our ability to properly underwrite and price risks and increased competition could adversely 
affect our results. 
Our financial condition, cash flow and results of operations depend on our ability to underwrite and set rates 
accurately for a full spectrum of risks. We establish our pricing based on assumptions about the level of 
losses that may occur within classes of business, geographic regions and other criteria.  
To properly price our products, we must collect, properly analyze and use data to make decisions and take 
appropriate action; the data must be sufficient, reliable and accessible; we need to develop appropriate 
rating methodologies and formulae; and we may need to identify and respond to trends quickly. Inflation 
trends, especially outside of historical norms, may make it more difficult to determine adequate pricing. If 
rates are not accurate, we may not generate enough premiums to offset losses and expenses or we may not 
be competitive in the marketplace.  
Our ability to set appropriate rates could be hampered if a state or states where we write business refuses to 
allow rate increases that we believe are necessary to cover the risks insured. At least one state requires us to 
purchase reinsurance from a mandatory reinsurance fund. Such reinsurance funds can create a credit risk 
for insurers if not adequately funded by the state and, in some cases, the existence of a reinsurance fund 
could affect the prices charged for our policies. The effect of these and similar arrangements could reduce 
our profitability in any given period or limit our ability to grow our business.  
The insurance industry is cyclical and intensely competitive. From time to time, the insurance industry goes 
through prolonged periods of intense competition during which it is more difficult to attract new business, 
retain existing business and maintain profitability. Competition in our insurance business is based on many 
factors, including:  
•  Competitiveness of premiums charged  
•  Relationships among carriers, agents, brokers and policyholders  
•  Underwriting and pricing methodologies that allow insurers to identify and flexibly price risks 
•  Compensation provided to agents 
•  Underwriting discipline 
• 
Terms and conditions of insurance coverage 
•  Speed with which products are brought to market 
•  Product and marketing innovations, including advertising 
• 
•  Ability to control expenses 
•  Adequacy of financial strength ratings by independent ratings agencies such as A.M. Best 
•  Quality of services provided to agents and policyholders 
•  Claims satisfaction and reputation 
If our pricing were incorrect or we were unable to compete effectively because of one or more of these 
factors, our premium writings could decline and our results of operations and financial condition could be 
materially adversely affected. 
Please see the discussion of our Commercial Lines, Personal Lines, Excess and Surplus Lines and Life 
Insurance Segments in Item 1, Page 12, Page 15 and Page 16, for a discussion of our competitive position in 
the insurance marketplace.

Our loss reserves, our largest liability, are based on estimates and could be inadequate to 
cover our actual losses. 
Our consolidated financial statements are prepared using GAAP. These principles require us to make 
estimates and assumptions that affect the amounts reported in the Consolidated Financial Statements and 
accompanying Notes. Actual results could differ materially from those estimates. For a discussion of the 
significant accounting policies we use to prepare our financial statements and the material implications of 
uncertainties associated with the methods, assumptions and estimates underlying our critical accounting 
policies, please refer to Item 8, Note 1 of the Consolidated Financial Statements, Page 105, and Item 7, 
Critical Accounting Estimates, Property Casualty Insurance Loss and Loss Expense Reserves and Life 
Insurance Policy Reserves, Page 41 and Page 44.  
Our most critical accounting estimate is loss reserves. Loss reserves are the amounts we expect to pay for 
covered claims and expenses we incur to settle those claims. The loss reserves we establish in our financial 
statements represent an estimate of amounts needed to pay and administer claims arising from insured 
events that have already occurred, including events that have not yet been reported to us. Loss reserves are 
estimates and are inherently uncertain; they do not and cannot represent an exact measure of liability. 
Inflationary scenarios, especially scenarios outside of historical norms, may make it more difficult to estimate 
loss reserves. Accordingly, our loss reserves for past periods could prove to be inadequate to cover our actual 
losses and related expenses. Any changes in these estimates are reflected in our results of operations during 
the period in which the changes are made. An increase in our loss reserves would decrease earnings, while a 
decrease in our loss reserves would increase earnings.  
The process used to determine our loss reserves is discussed in Item 7, Critical Accounting Estimates, 
Property Casualty Insurance Loss and Loss Expense Reserves and Life Insurance Policy Reserves, Page 41 
and Page 44. 
Unforeseen losses, the type and magnitude of which we cannot predict, may emerge in the future. 
These additional losses could arise from changes in the legal environment, laws and regulations, climate 
change, catastrophic events, increases in loss severity or frequency, or other causes. Such future losses 
could be substantial. Inflationary scenarios may cause the cost of claims, especially medical claims, to rise, 
impacting reserve adequacy and our results of operations.  
Our ability to obtain or collect on our reinsurance protection could affect our business, 
financial condition, results of operations and cash flows. 
We buy property casualty and life reinsurance coverage to mitigate the liquidity risk and earnings volatility 
risk of an unexpected rise in claims severity or frequency from catastrophic events or a single large loss. The 
availability, amount and cost of reinsurance depend on market conditions and may vary significantly. If we 
were unable to obtain reinsurance on acceptable terms and in appropriate amounts, our business and 
financial condition could be adversely affected.  
In addition, we are subject to credit risk with respect to our reinsurers. Although we purchase reinsurance to 
manage our risks and exposures to losses, this reinsurance does not discharge our direct obligations under 
the policies we write. We would remain liable to our policyholders even if we were unable to recover what we 
believe we are entitled to receive under our reinsurance contracts. Reinsurers might refuse or fail to pay 
losses that we cede to them, or they might delay payment. For long-tail claims, the creditworthiness of our 
reinsurers may change before we can recover amounts to which we are entitled. A reinsurer’s insolvency, 
inability or unwillingness to make payments under the terms of its reinsurance agreement with our 
insurance subsidiaries could have a material adverse effect on our financial position, results of operations 
and cash flows. 
We participated in USAIG, a joint underwriting association of individual insurance companies that collectively 
functions as a worldwide insurance market for all types of aviation and aerospace accounts. Our participation 
was terminated after policy year 2002. At year-end 2010, 19 percent, or $110 million, of our total 
reinsurance receivables were related to USAIG, primarily for events of September 11, 2001, offset by 
$118 million of amounts ceded to other pool participants and reinsurers. If the pool participants and 
reinsurers were unable to fulfill their financial obligations and all security collateral that supports the 
participants’ obligations became worthless, we could be liable for an additional pool liability of $230 million 
and our financial position and results of operations could be materially affected. Currently all pool 
participants and reinsurers are financially solvent. 
Please see Item 7, 2011 Reinsurance Programs, Page 90, for a discussion of our reinsurance treaties. 
Our business depends on the uninterrupted operation of our facilities, systems and 
business functions. 
Our business depends on our associates’ ability to perform necessary business functions, such as 
processing new and renewal policies and claims. We increasingly rely on technology and systems to 
accomplish these business functions in an efficient and uninterrupted fashion. Our inability to access our 
headquarters facilities or a failure of technology, telecommunications or other systems could significantly 

Cincinnati Financial Corporation – 2010 10-K – Page 28 

impair our ability to perform such functions on a timely basis or affect the accuracy of transactions. If 
sustained or repeated, such a business interruption or system failure could result in a deterioration of our 
ability to write and process new and renewal business, serve our agents and policyholders, pay claims in a 
timely manner, collect receivables or perform other necessary business functions. If our disaster recovery 
and business continuity plans did not sufficiently consider, address or reverse the circumstances of an 
interruption or failure, this could result in a materially adverse effect on our operating results and financial 
condition. This risk is exacerbated because approximately 70 percent of our associates work at our 
Fairfield, Ohio, headquarters. 
The effects of changes in industry practices, laws and regulations on our business 
are uncertain. 
As industry practices and legal, judicial, legislative, regulatory, political, social and other environmental 
conditions change, unexpected and unintended issues related to insurance pricing, claims and coverage, 
may emerge. These issues may adversely affect our business by impeding our ability to obtain adequate 
rates for covered risks, extending coverage beyond our underwriting intent or by increasing the number or 
size of claims. In some instances, unforeseeable emerging and latent claim and coverage issues may not 
become apparent until sometime after we have issued the insurance policies that could be affected by the 
changes. As a result, the full extent of liability under our insurance contracts may not be known for many 
years after a policy is issued. 
We are required to adopt new or revised accounting standards issued by recognized authoritative 
organizations, including the Financial Accounting Standards Board and the SEC. Future changes required to 
be adopted could change the current accounting treatment that we apply and could result in material 
adverse effects on our results of operations and financial condition.  
The National Association of Insurance Commissioners (NAIC), state insurance regulators and state legislators 
continually re-examine existing laws and regulations governing insurance companies and insurance holding 
companies, specifically focusing on modifications to statutory accounting principles, interpretations of 
existing laws, regulations relating to product forms and pricing methodologies and the development of new 
laws and regulations that affect a variety of financial and nonfinancial components of our business. Any 
proposed or future legislation, regulation or NAIC initiatives, if adopted, may be more restrictive on our ability 
to conduct business than current regulatory requirements or may result in higher costs. 
Federal laws and regulations, including those that may be enacted in the wake of the financial and credit 
crises, may have adverse affects on our business, potentially including a change from a state-based system 
of regulation to a system of federal regulation, the repeal of the McCarran Ferguson Act, and/or measures 
under the Dodd-Frank Act that establish the Federal Insurance Office and provide for a determination that a 
non-bank financial company presents systemic risk and therefore should be subject to heightened 
supervision by the Federal Reserve Board. Adoption or implementation of any of these measures may restrict 
our ability to conduct our insurance business, govern our corporate affairs or increase our cost of doing 
business. 
The effects of such changes could adversely affect our results of operations. Please see Item 7, Critical 
Accounting Estimates, Property Casualty Insurance Loss and Loss Expense Reserves and Life Insurance 
Policy Reserves, Page 41 and Page 44, for a discussion of our reserving practices. 
Managing technology initiatives and meeting new data security requirements are 
significant challenges. 
While technology can streamline many business processes and ultimately reduce the cost of operations, 
technology initiatives present short-term cost, and also have implementation and operational risks. In 
addition, we may have inaccurate expense projections, implementation schedules or expectations regarding 
the effectiveness and user acceptance of the end product. These issues could escalate over time. If we were 
unable to find and retain employees with key technical knowledge, our ability to develop and deploy key 
technology solutions could be hampered. 
We necessarily collect, use and hold data concerning individuals and businesses with whom we have a 
relationship. Threats to data security rapidly emerge and change, exposing us to rising costs and 
competing time constraints to secure our data in accordance with customer expectations and statutory and 
regulatory requirements. A breach of our security that results in unauthorized access to our data could 
expose us to data loss, litigation, damages, fines and penalties, significant increases in compliance costs and 
reputational damage. 
Please see Item 1, Strategic Initiatives, Page 9 for a discussion of our technology initiatives.  
Our status as an insurance holding company with no direct operations could affect our ability 
to pay dividends in the future. 
Cincinnati Financial Corporation is a holding company that transacts substantially all of its business 
through its subsidiaries. Our primary assets are the stock in our operating subsidiaries and our 
investments. Consequently, our cash flow to pay cash dividends and interest on our long-term debt depends 

Cincinnati Financial Corporation – 2010 10-K – Page 29 

Properties  

Unresolved Staff Comments 

on dividends we receive from our operating subsidiaries and income earned on investments held at the 
parent-company level.  
Dividends paid to our parent company by our insurance subsidiary are restricted by the insurance laws of 
Ohio, its domiciliary state. These laws establish minimum solvency and liquidity thresholds and limits. 
Currently, the maximum dividend that may be paid without prior regulatory approval is limited to the greater 
of 10 percent of statutory surplus or 100 percent of statutory net income for the prior calendar year, up to 
the amount of statutory unassigned surplus as of the end of the prior calendar year. Dividends exceeding 
these limitations may be paid only with prior approval of the Ohio Department of Insurance. Consequently, at 
times, we might not be able to receive dividends from our insurance subsidiary, or we might not receive 
dividends in the amounts necessary to meet our debt obligations or to pay dividends on our common stock 
without liquidating securities. This could affect our financial position. 
Please see Item 1, Regulation, Page 22, and Item 8, Note 9 of the Consolidated Financial Statements, 
Page 118, for discussion of insurance holding company dividend regulations.

We did not sell any of our shares that were not registered under the Securities Act during 2010. The board of 
directors has authorized share repurchases since 1996. Purchases are expected to be made generally 
through open market transactions. The board gives management discretion to purchase shares at 
reasonable prices in light of circumstances at the time of purchase, subject to U.S. Securities and Exchange 
Commission (SEC) regulations. During 2010, we repurchased 377,748 shares at an average cost of 
$26.49 per share. 
On October 24, 2007, the board of directors expanded the existing repurchase authorization to 
approximately 13 million shares. The prior repurchase program for 10 million shares was announced in 
2005, replacing a program that had been in effect since 1999. No repurchase program has expired during 
the period covered by the above table. Neither the 2005 nor 1999 program had an expiration date, but no 
further repurchases will occur under the 1999 program.

Cumulative Total Return 
As depicted in the graph below, the five–year total return on a $100 investment made December 31, 2005,

Realized investment gains and losses are integral to our financial results over the long term, but our 
substantial discretion in the timing of investment sales may cause this value to fluctuate 
substantially. Also, applicable accounting standards require us to recognize gains and losses from 
certain changes in fair values of securities and embedded derivatives without actual realization of 
those gains and losses. We discuss realized investment gains for the past three years in Item 7, 
Investments Results of Operations, Page 75.

Management's Discussion and Analysis of Financial 
Condition and Results of Operations  

INTRODUCTION 
The purpose of Management’s Discussion and Analysis is to provide an understanding of Cincinnati Financial 
Corporation’s consolidated results of operations and financial condition. Our Management’s Discussion and 
Analysis should be read in conjunction with Item 6, Selected Financial Data, Pages 34 and 35, and Item 8, 
Consolidated Financial Statements and related Notes, beginning on Page 105. We present per share data on 
a diluted basis unless otherwise noted, adjusting those amounts for all stock splits and stock dividends.  
We begin with an executive summary of our results of operations and outlook, as well as details on 
critical accounting policies and estimates. Periodically, we refer to estimated industry data so that we can 
give information on our performance within the context of the overall insurance industry. Unless 
otherwise noted, the industry data is prepared by A.M. Best, a leading insurance industry statistical, 
analytical and financial strength rating organization. Information from A.M. Best is presented on a 
statutory accounting basis. When we provide our results on a comparable statutory accounting basis, we 
label it as such; all other company data is presented in accordance with accounting principles generally 
accepted in the United States of America (GAAP). 
EXECUTIVE SUMMARY 
Through The Cincinnati Insurance Company, Cincinnati Financial Corporation is one of the 25 largest property 
casualty insurers in the nation, based on 2009 written premium volume for approximately 2,000 U.S. stock 
and mutual insurer groups. We market our insurance products through a select group of independent 
insurance agencies in 39 states as discussed in Item 1, Our Business and Our Strategy, Page 3. 
Although recent years have been difficult for our economy, our industry and our company, our long-term 
perspective lets us address the immediate challenges while focusing on the major decisions that best 
position the company for success through all market cycles. We believe that this forward-looking view has 
consistently benefited our shareholders, agents, policyholders and associates. 
To measure our progress, we have defined a measure of value creation that we believe captures the 
contribution of our insurance operations, the success of our investment strategy and the importance 
we place on paying cash dividends to shareholders. We refer to this measure as our value creation ratio, 
or VCR, and it is made up of two primary components: (1) our rate of growth in book value per share 
plus (2) the ratio of dividends declared per share to beginning book value per share. For the period 
2010 through 2014, an annual value creation ratio averaging 12 percent to 15 percent is our primary 
performance target. Management believes this non-GAAP measure is a useful supplement to GAAP 
information. With heightened economic and market uncertainty since 2008, we believe the long-term nature 
of this ratio is an appropriate way to measure our long-term progress in creating shareholder value.

When looking at our longer-term objectives, we see three performance drivers: 
•  Premium growth – We believe over any five-year period our agency relationships and initiatives can lead 
to a property casualty written premium growth rate that exceeds the industry average. The compound 
annual growth rate of our net written premiums was negative 0.7 percent over the five-year period 
2006 through 2010, slightly lower than the negative 0.5 percent estimated growth rate for the property 
casualty insurance industry.  

•  Combined ratio – We believe our underwriting philosophy and initiatives can generate a GAAP combined 
ratio over any five-year period that is consistently below 100 percent. Our GAAP combined ratio has 
averaged 98.3 percent over the five-year period 2006 through 2010. Our combined ratio was below 
100 percent in 2006 and 2007, but was above 100 percent for 2008 through 2010, when we averaged 
102.3 percent, including an average catastrophe loss ratio that was 2.1 percentage points higher than 
the average for the 10-year period prior to 2008. Performance as measured by the combined ratio is 
discussed in Consolidated Property Casualty Insurance Results of Operations, Page 49. Our statutory 
combined ratio averaged 98.2 percent over the five-year period 2006 through 2010 compared with an 
estimated 99.5 percent for the property casualty industry.  

Cincinnati Financial Corporation – 2010 10-K – Page 36 

 
• 

Investment contribution - We believe our investment philosophy and initiatives can drive investment 
income growth and lead to a total return on our equity investment portfolio over a five-year period that 
exceeds the five-year return of the Standard & Poor’s 500 Index.  
o 

Investment income growth, on a before-tax basis, declined at a compound annual rate of 0.3 percent 
over the five-year period 2006 through 2010. It grew in each year except 2008 and 2009, when 
we experienced a dramatic reduction in dividend payouts by financial services companies held in our 
equity portfolio, a risk we addressed aggressively during 2008, completing that effort in early 2009. 
o  Over the five years ended December 31, 2010, our compound annual equity portfolio return was a 
negative 3.0 percent compared with a compound annual total return of 2.3 percent for the Index. 
Our equity portfolio underperformed the market for the five-year period primarily because of the 
2008 decline in the market value of our previously large holdings in the financial services sector. For 
the year 2010, our compound annual equity portfolio return was 11.0 percent, compared with 
15.1 percent for the Index, as the broad market rally did not favor the higher quality, dividend-paying 
stocks we prefer.  

The board of directors is committed to rewarding shareholders directly through cash dividends and through 
authorizing share repurchases. The board also has periodically declared stock dividends and splits. Through 
2010, the company has increased the indicated annual cash dividend rate for 50 consecutive years, a record 
we believe is matched by only 10 other publicly traded companies. The board regularly evaluates relevant 
factors in dividend-related decisions, and the increase reflects confidence in our strong capital, liquidity and 
financial flexibility, as well as progress through our initiatives to improve earnings performance. We discuss 
our financial position in more detail in Liquidity and Capital Resources, Page 78.  
Strategic Initiatives Highlights 
Management has worked to identify a strategy that can lead to long-term success, with concurrence by the 
board of directors. Our strategy is intended to position us to compete successfully in the markets we have 
targeted while appropriately managing risk. We discuss our long-term, proven strategy in Item 1, Our 
Business and Our Strategy, Page 3. We believe successful implementation of initiatives that support our 
strategy will help us better serve our agent customers and reduce volatility in our financial results while we 
also grow earnings and book value over the long-term, successfully navigating challenging economic, market 
or industry pricing cycles.  
• 

Improve insurance profitability – Implementation of these initiatives is intended to improve pricing 
capabilities for our property casualty business, increasing our ability to manage our business while also 
enhancing our efficiency. Improved pricing capabilities through the use of technology and analytics can 
lead to better profit margins. Improved planning for growth and profitability plans can enhance our ability 
to achieve objectives at all levels in the organization. Improved internal processes with additional 
performance metrics can help us be more efficient and effective. These initiatives also support the ability 
of the agencies that represent us to grow profitably by allowing them to serve clients faster and to more 
efficiently manage agency expenses. 

•  Drive premium growth – Implementation of these initiatives is intended to further penetrate each market 
we serve through our independent agency network. Strategies aimed at specific market opportunities, 
along with service enhancements, can help our agents grow and increase our share of their business. 
Diversified growth also may reduce variability of losses from weather-related catastrophes.  

We discuss these strategic initiatives, along with related metrics to assess progress, in Item 1, Strategic 
Initiatives, Page 9,  
Factors Influencing Our Future Performance  
In 2010, our value creation ratio of 11.1 percent was slightly below our target annual average of 12 percent 
to 15 percent for the period 2010 through 2014. In 2009, the ratio exceeded our target and in 2008, it was 
below our target, as discussed in the review of our financial highlights below. For the year 2011, we believe 
our value creation ratio may be below our long-term target for several reasons.  
• 

The rally in financial markets during 2009 and 2010 had a highly favorable impact on our value creation 
ratio, offsetting much of the unfavorable impact of the sharp decline in financial markets during 2008. 
Should financial markets decline during 2011, which could occur as part of typical market volatility 
patterns, the related component of our 2011 value creation ratio could also register a weak or 
negative result.  

• 

Lingering effects of soft insurance market pricing are expected to affect growth rates and earned 
premium levels into 2011 and for some time into the future, depending on insurance market conditions. 
Current conditions continue to weaken loss ratios and hamper near-term profitability. Economic factors, 
including inflation, may increase our claims and settlement expenses related to medical care, litigation 
and construction.  

Cincinnati Financial Corporation – 2010 10-K – Page 37 

• 

The slowly recovering economy is expected to continue to affect policyholders by minimizing growth in 
value of their business and personal insurable assets. Until the economy significantly strengthens, we 
may experience only modest premium growth for the property casualty industry or our commercial lines 
segment, which represented approximately 73 percent of our 2010 property casualty net written 
premiums. Property casualty written premium growth also may lag as some of our growth initiatives 
require more time to reach their full contribution.  

•  We will incur the cost of continued investment in our business, including technology, recent entry in new 
states and process initiatives to create long-term value. In addition, we will not see the full advantage of 
many of these investments for several years.  

Our view of the value we can create over the next five years relies on two assumptions about the external 
environment. First, we anticipate some firming of commercial insurance pricing by the end of 2011. Second, 
we assume that the economy can continue on a growth track during 2011. If those assumptions prove to be 
inaccurate, we may not be able to achieve our performance targets even if we accomplish our strategic 
objectives.  
Other factors that could influence our ability to achieve our target include: 
•  We expect the insurance marketplace to remain competitive, which is likely to cause carriers to 

pursue strategies that they believe could lead to economies of scale, market share gains or the potential 
for an improved competitive posture.  

•  We expect the independent insurance agency system to remain strong and viable, with continued agency 
consolidation, especially as agency margins come under more pressure due to soft pricing and the 
difficult economic environment. The soft commercial market that has extended into 2011 creates 
additional risk for agencies. We expect the soft market to continue for much of 2011, or perhaps longer, 
particularly in non-catastrophe-event-prone states and lines of business, absent a significant event or 
events. 

•  We expect initiatives that make it easier for agents to do business with us will continue to be a significant 

factor in agency relationships, with technology being a major driver. Policyholders will increasingly 
demand online services and access from agents or carriers. 

We discuss in our Item 1A, Risk Factors, Page 24, many potential risks to our business and our ability to 
achieve our qualitative and quantitative objectives. These are real risks, but their probability of occurring may 
not be high. We also believe that our risk management programs generally could mitigate their potential 
effects, in the event they would occur. We continue to study emerging risks, including climate change risk 
and its potential financial effects on our results of operation and those we insure. These effects include 
deterioration in credit quality of our municipal or corporate bond portfolios and increased losses without 
sufficient corresponding increases in premiums. As with any risk, we seek to identify the extent of the risk 
exposure and possible actions to mitigate potential negative effects of risk, at an enterprise level. 
We have formal risk management programs overseen by a senior officer and supported by a team of 
representatives from business areas. The team provides reports to our chairman, our president and chief 
executive officer and our board of directors, as appropriate, on risk assessments, risk metrics and risk plans. 
Our use of operational audits, strategic plans and departmental business plans, as well as our culture of 
open communications and our fundamental respect for our Code of Conduct, continue to help us manage 
risks on an ongoing basis.  
Below we review highlights of our financial results for the past three years. Detailed discussion of these 
topics appears in Results of Operations, Page 48, and Liquidity and Capital Resources, Page 78.

CORPORATE FINANCIAL HIGHLIGHTS 
The value creation ratio discussed in the Executive Summary, Page 36, was 11.1 percent in 2010, 
19.7 percent in 2009 and negative 23.5 percent in 2008. The book value per share growth component of 
the value creation ratio was 5.7 percent during 2010 and 13.6 percent during 2009, largely reflecting 
improved valuation of our investment portfolio in addition to earnings. In 2008, a decline in unrealized gains 
on our investment portfolio was the most significant factor in the 27.9 percent decline in book value. Net 
income declined 13 percent in 2010 after growing 1 percent in 2009, reflecting lower realized investment 
gains. In 2008, net income was down 47 percent. Cash dividends declared per share rose approximately 
1 percent in 2010, 1 percent in 2009 and 10 percent in 2008.

Invested assets grew significantly during both 2010 and 2009 primarily due to strong performance in the 
financial markets, reversing the trend of 2008 from lower fair values for portfolio investments, largely due to 
economic factors. Entering 2011, the portfolio continues to be well-diversified and we believe it is well-
positioned to withstand short-term fluctuations. We discuss our investment strategy in Item 1, Investments 
Segment, Page 19, and results for the segment in Investment Results of Operations, Page 75. 
Our ratio of debt to total capital (debt plus shareholders’ equity) decreased in both 2010 and 2009 and is 
comfortably within our target range.

Net income in 2010 was $55 million or 13 percent lower than in 2009, due primarily to the after-tax effects 
of net realized investment gains that were $114 million lower, partially offset by a $53 million improvement 
from property casualty underwriting results plus $9 million growth in investment income. Net income 
increased $3 million in 2009, reflecting the after-tax net effect of three major contributing items: a 
$132 million increase from net realized investment gains, partially offset by a $48 million decrease from 
investment income and a $74 million decrease from property casualty underwriting results. 
Weighted average shares outstanding may fluctuate from period to period due to repurchases of shares 
under board authorizations or issuance of shares through equity compensation plans. Weighted average 
shares outstanding on a diluted basis increased by less than 1 million in 2010, after declining by less than 
1 million in 2009 and by 9 million in 2008. 
As discussed in Investment Results of Operations, Page 75, security sales led to realized investment gains in 
all three years, although 2008 gains were tempered by $510 million in other-than-temporary impairment 
(OTTI) charges. Realized investment gains and losses are integral to our financial results over the long term. 
We have substantial discretion in the timing of investment sales and, therefore, the gains or losses that are 
recognized in any period. That discretion generally is independent of the insurance underwriting process. 
Also, applicable accounting standards require us to recognize gains and losses from certain changes in fair 
values of securities and for securities with embedded derivatives without actual realization of those gains 
and losses.

Higher interest income drove 3 percent growth in 2010 pretax investment income. Lower income from 
common stock dividends led to a 7 percent decline in 2009 pretax net investment income, improving on a 
12 percent decline for 2008, which was the first decline for this measure in company history. The primary 
reason for the decline was dividend reductions by common and preferred holdings, including reductions 
during the year on positions sold or reduced.

Property casualty written premiums grew 2 percent in 2010, reversing the trend of 3 percent declines in both 
2009 and 2008. Earned premiums also reversed the prior year trend, growing slightly in 2010. Trends and 
related factors discussed in Commercial Lines, Personal Lines and Excess and Surplus Lines Insurance 
Results of Operations, beginning on Page 54, Page 64 and Page 70, respectively. 
Our property casualty insurance operations reported an underwriting loss in each of the last three years, but 
the amount of loss in 2010 was less than half that of 2009. We measure property casualty underwriting 
profitability primarily by the combined ratio. Our combined ratio measures the percentage of each earned 
premium dollar spent on claims plus all expenses related to our property casualty operations. A lower ratio 
indicates more favorable results and better underlying performance. Our combined ratio was over 
100 percent in each of the last three years. Initiatives to improve our combined ratio are discussed in Item 1, 
Strategic Initiatives, Page 9. In 2010, 2009 and 2008, favorable development on reserves for claims that 
occurred in prior accident years helped offset other incurred loss and loss expenses. Reserve development is 
discussed further in Property Casualty Loss and Loss Expense Obligations and Reserves, beginning on 
Page 82. Losses from weather-related catastrophes are another important item influencing the combined 
ratio and are discussed along with other factors in Commercial Lines, Personal Lines and Excess and Surplus 
Lines Insurance Results of Operations, beginning on Page 54, Page 64 and Page 70, respectively.  
Our life insurance segment continued to provide a consistent source of profit. We discuss results for the 
segment in Life Insurance Results of Operations, Page 73. Investment income and realized investment gains 
from the life insurance investment portfolio are included in Investments segment results. 
CRITICAL ACCOUNTING ESTIMATES 
Cincinnati Financial Corporation’s financial statements are prepared using GAAP. These principles require 
management to make estimates and assumptions that affect the amounts reported in the Consolidated 
Financial Statements and accompanying Notes. Actual results could differ materially from those estimates. 
The significant accounting policies used in the preparation of the financial statements are discussed in 
Item 8, Note 1 of the Consolidated Financial Statements, Page 105 In conjunction with that discussion, 
material implications of uncertainties associated with the methods, assumptions and estimates underlying 
the company’s critical accounting policies are discussed below. The audit committee of the board of directors 
reviews the annual financial statements with management and the independent registered public accounting 
firm. These discussions cover the quality of earnings, review of reserves and accruals, reconsideration of the 
suitability of accounting principles, review of highly judgmental areas including critical accounting policies, 
audit adjustments and such other inquiries as may be appropriate.

PROPERTY CASUALTY INSURANCE LOSS AND LOSS EXPENSE RESERVES 
We establish loss and loss expense reserves for our property casualty insurance business as balance sheet 
liabilities. These reserves account for unpaid loss and loss expenses as of a financial statement date. Unpaid 
loss and loss expenses are the estimated amounts necessary to pay for and settle all outstanding insured 
claims, including incurred but not reported (IBNR) claims, as of that date.  
For some lines of business that we write, a considerable and uncertain amount of time can elapse between 
the occurrence, reporting and payment of insured claims. The amount we will actually have to pay for such 
claims also can be highly uncertain. This uncertainty, together with the size of our reserves, makes the loss 
and loss expense reserves our most significant estimate. Gross loss and loss expense reserves were 
$4.137 billion at year-end 2010 compared with $4.096 billion at year-end 2009.  
How Reserves Are Established  
Our field claims representatives establish case reserves when claims are reported to the company to provide 
for our unpaid loss and loss expense obligation associated with individual claims. Field claims managers 
supervise and review all claims with case reserves less than $35,000. Experienced headquarters claims 
supervisors review individual case reserves greater than $35,000 that were established by field claims 
representatives. Headquarters claims managers also review case reserves greater than $100,000.  
Our claims representatives base their case reserve estimates primarily upon case-by-case evaluations that 
consider: 
• 
• 
• 
• 
• 
Case reserves of all sizes are subject to review on a 90-day cycle, or more frequently if new information 
about a loss becomes available. As part of the review process, we monitor industry trends, cost trends, 
relevant court cases, legislative activity and other current events in an effort to ascertain new or additional 
loss exposures. 
We also establish IBNR reserves to provide for all unpaid loss and loss expenses not accounted for by case 
reserves: 
• 

potential for subrogation or salvage recoverable 

For weather events designated as catastrophes, we calculate IBNR reserves directly as a result of an 
estimated IBNR claim count and an estimated average claim amount for each event. Once case reserves 
are established for a weather event we reduce the IBNR reserves. Our claims department management 
coordinates the assessment of these events and prepares the related IBNR reserve estimates. Such an 
assessment involves a comprehensive analysis of the nature of the storm, of policyholder exposures 
within the affected geographic area and of available claims intelligence. Depending on the nature of the 
event, available claims intelligence could include surveys of field claims associates within the affected 
geographic area, feedback from a catastrophe claims team sent into the area, as well as data on claims 
reported as of the financial statement date. We generally use the catastrophe definition provided by 
Property Claims Service (PCS), a division of Insurance Services Office (ISO). PCS defines a catastrophe as 
an event that causes countrywide damage of $25 million or more in insured property losses and affects 
a significant number of policyholders and insureds.

For asbestos and environmental claims, we calculate IBNR reserves by deriving an actuarially based 
estimate of total unpaid loss and loss expenses. We then reduce the estimate by total case reserves. 
We discuss the reserve analysis that applies to asbestos and environmental reserves in Asbestos and 
Environmental Reserves, Page 84. 

For all other claims and events, IBNR reserves are calculated as the difference between an actuarial 
estimate of the ultimate cost of total loss and loss expenses incurred reduced by the sum of total loss 
and loss expense payments and total case reserves estimated for individual claims. We discuss 
below the development of actuarially based estimates of the ultimate cost of total loss and loss 
expenses incurred. 

Our actuarial staff applies significant judgment in selecting models and estimating model parameters when 
preparing reserve analyses. In addition, unpaid loss and loss expenses are inherently uncertain as to 
timing and amount. Uncertainties relating to model appropriateness, parameter estimates and actual loss 
and loss expense amounts are referred to as model, parameter and process uncertainty, respectively. Our 
management and actuarial staff address these uncertainties in the reserving process in a variety of ways.

individual and multiple probabilistic trend family models 

Our actuarial staff bases its IBNR reserve estimates for these losses primarily on the indications of methods 
and models that analyze accident year data. Accident year is the year in which an insured claim, loss, or loss 
expense occurred. The specific methods and models that our actuaries have used for the past several 
years are: 
• 
• 
• 
Our actuarial staff uses diagnostics provided by stochastic reserving software to evaluate the 
appropriateness of the models and methods listed above. The software’s diagnostics have indicated that the 
appropriateness of these models and methods for estimating IBNR reserves for our lines of business tends to 
depend on a line's tail. Tail refers to the time interval between a typical claim's occurrence and its settlement. 
For our long-tail lines such as workers’ compensation and commercial casualty, models from the probabilistic 
trend family tend to provide superior fits and to validate well compared with models underlying the loss 
development and Bornhuetter-Ferguson methods. The loss development and Bornhuetter-Ferguson methods, 
particularly the reported loss variations, tend to produce the more appropriate IBNR reserve estimates for our 
short-tail lines such as homeowner and commercial property. For our mid-tail lines such as personal and 
commercial auto liability, all models and methods provide useful insights. 
Our actuarial staff also devotes significant time and effort to the estimation of model and method 
parameters. The loss development and Bornhuetter-Ferguson methods require the estimation of numerous 
loss development factors. The Bornhuetter-Ferguson methods also involve the estimation of numerous 
ultimate loss ratios by accident year. Models from the probabilistic trend family require the estimation of 
development trends, calendar year inflation trends and exposure levels. Consequently, our actuarial staff 
monitors a number of trends and measures to gain key business insights necessary for exercising 
appropriate judgment when estimating the parameters mentioned.  
These trends and measures include:  
• 
• 
• 
• 
• 
• 
These trends and measures also support the estimation of ultimate accident year loss ratios needed 
for applying the Bornhuetter-Ferguson methods and for assessing the reasonability of all IBNR reserve 
estimates computed. Our actuarial staff reviews these trends and measures quarterly, updating parameters 
derived from them as necessary. 
Quarterly, our actuarial staff summarizes its reserve analysis by preparing an actuarial best estimate and a 
range of reasonable IBNR reserves intended to reflect the uncertainty of the estimate. An inter-departmental 
committee that includes our actuarial management team reviews the results of each quarterly reserve 
analysis. The committee establishes management’s best estimate of IBNR reserves, which is the amount that 
is included in each period’s financial statements. In addition to the information provided by actuarial staff, 
the committee also considers factors such as the following: 
• 
•  new business activity 
• 
judicial decisions 
• 
• 
• 
• 
The determination of management's best estimate, like the preparation of the reserve analysis that supports 
it, involves considerable judgment. Changes in reserving data or the trends and factors that influence 
reserving data may signal fundamental shifts or may simply reflect single-period anomalies. Even if a change 
reflects a fundamental shift, the full extent of the change may not become evident until years later. 
Moreover, since our methods and models do not explicitly relate many of the factors we consider directly to 
reserve levels, we typically cannot quantify the precise impact of such factors on the adequacy of reserves 
prospectively or retrospectively.

Due to the uncertainties described above, our ultimate loss experience could prove better or worse than our 
carried reserves reflect. To the extent that reserves are inadequate and increased, the amount of the 
increase is a charge in the period that the deficiency is recognized, raising our loss and loss expense ratio 
and reducing earnings. To the extent that reserves are redundant and released, the amount of the release is 
a credit in the period that the redundancy is recognized, reducing our loss and loss expense ratio and 
increasing earnings. 
Key Assumptions - Loss Reserving 
Our actuarial staff makes a number of key assumptions when using their methods and models to derive IBNR 
reserve estimates. Appropriate reliance on these key assumptions essentially entails determinations of the 
likelihood that statistically significant patterns in historical data may extend into the future. The four most 
significant of the key assumptions used by our actuarial staff and approved by management are: 
•  Emergence of loss and allocated loss expenses on an accident year basis. Historical paid loss, 

reported loss and paid allocated loss expense data for the business lines we analyze contain 
patterns that reflect how unpaid losses, unreported losses and unpaid allocated loss expenses as of a 
financial statement date will emerge in the future on an accident year basis. Unless our actuarial staff or 
management identifies reasons or factors that invalidate the extension of historical patterns into 
the future, these patterns can be used to make projections necessary for estimating IBNR reserves. 
Our actuaries significantly rely on this assumption in the application of all methods and models 
mentioned above. 

•  Calendar year inflation. For long-tail and mid-tail business lines, calendar year inflation trends for 

future paid losses and paid allocated loss expenses will not vary significantly from a stable, long-term 
average. Our actuaries base reserve estimates derived from probabilistic trend family models on 
this assumption. 

•  Exposure levels. Historical earned premiums, when adjusted to reflect common levels of product pricing 

and loss cost inflation, can serve as a proxy for historical exposures. Our actuaries require this 
assumption to estimate expected loss ratios and expected allocated loss expense ratios used by the 
Bornhuetter-Ferguson reserving methods. They also use this assumption to establish exposure levels for 
recent accident years, characterized by “green” or immature data, when working with probabilistic trend 
family models. 

•  Claims having atypical emergence patterns. Characteristics of certain subsets of claims, such as high 

frequency, high severity, or mass tort claims, have the potential to distort patterns contained in historical 
paid loss, reported loss and paid allocated loss expense data. When testing indicates this to be the case 
for a particular subset of claims, our actuaries segregate these claims from the data and analyze them 
separately. Subsets of claims that could fall into this category include hurricane claims, individual large 
claims and asbestos and environmental claims.  

These key assumptions have not changed since 2005, when our actuarial staff began using probabilistic 
trend family models to estimate IBNR reserves.  
Paid losses, reported losses and paid allocated loss expenses are subject to random as well as systematic 
influences. As a result, actual paid losses, reported losses and paid allocated loss expenses are virtually 
certain to differ from projections. Such differences are consistent with what specific models for our 
business lines predict and with the related patterns in the historical data used to develop these models. As a 
result, management does not closely monitor statistically insignificant differences between actual and 
projected data.  
Reserve Estimate Variability 
Management believes that the standard error of a reserve estimate, a measure of the estimate's variability, 
provides the most appropriate measure of the estimate's sensitivity. The reserves we establish depend on 
the models we use and the related parameters we estimate in the course of conducting reserve analyses. 
However, the actual amount required to settle all outstanding insured claims, including IBNR claims, as of a 
financial statement date depends on stochastic, or random, elements as well as the systematic elements 
captured by our models and estimated model parameters. For the lines of business we write, process 
uncertainty – the inherent variability of loss and loss expense payments – typically contributes more to the 
imprecision of a reserve estimate than parameter uncertainty.  
Consequently, a sensitivity measure that ignores process uncertainty would provide an incomplete picture of 
the reserve estimate's sensitivity. Since a reserve estimate's standard error accounts for both process and 
parameter uncertainty, it reflects the estimate's full sensitivity to a range of reasonably likely scenarios. 
The table below provides standard errors and reserve ranges by property casualty line of business and in 
total for loss and loss expense reserves as well as the potential effects on our net income, assuming a 
35 percent federal tax rate. Standard errors and reserve ranges for assorted groupings of these lines of 

Cincinnati Financial Corporation – 2010 10-K – Page 43 

business cannot be computed by simply adding the standard errors and reserve ranges of the component 
lines of business, since such an approach would ignore the effects of product diversification. See Range of 
Reasonable Reserves, Page 83, for more details on our total reserve range. While the table reflects our 
assessment of the most likely range within which each line's actual unpaid loss and loss expenses may 
fall, one or more lines' actual unpaid loss and loss expenses could nonetheless fall outside of the 
indicated ranges.

If actual unpaid loss and loss expenses fall within these ranges, our cash flow and fixed maturity investments 
should provide sufficient liquidity to make the subsequent payments. To date, our cash flow has covered our 
loss and loss expense payments, and we have never had to sell investments to make these payments. If this 
were to become necessary, however, our fixed maturity investments should provide us with ample liquidity. At 
year-end 2010, consolidated fixed maturity investments exceeded total insurance reserves (including life 
policy reserves) by $2.149 billion. 
LIFE INSURANCE POLICY RESERVES 
We establish the reserves for traditional life insurance policies based on expected expenses, mortality, 
morbidity, withdrawal rates and investment yields, including a provision for uncertainty. Once these 
assumptions are established, they generally are maintained throughout the lives of the contracts. We use 
both our own experience and industry experience adjusted for historical trends in arriving at our assumptions 
for expected mortality, morbidity and withdrawal rates. We use our own experience and historical trends for 
setting our assumptions for expected expenses. We base our assumptions for expected investment income 
on our own experience adjusted for current economic conditions. 
We establish reserves for our universal life, deferred annuity and investment contracts equal to the 
cumulative account balances, which include premium deposits plus credited interest less charges and 
withdrawals. Some of our universal life insurance policies contain no-lapse guarantee provisions. For these 
policies, we establish a reserve in addition to the account balance based on expected no-lapse guarantee 
benefits and expected policy assessments. 
ASSET IMPAIRMENT 
Our fixed-maturity and equity investment portfolios are our largest assets. The company’s asset impairment 
committee continually monitors the holdings in these portfolios and all other assets for signs of other-than-
temporary or permanent impairment. The committee monitors significant decreases in the fair value of 
invested assets, an accumulation of costs in excess of the amount originally expected to acquire or construct 
an asset, uncollectability of all receivable assets, or other factors such as bankruptcy, deterioration of 
creditworthiness, failure to pay interest or dividends, signs indicating that the carrying amount may not be 
recoverable, or changes in legal factors or in the business climate.  
The application of our impairment policy resulted in OTTI charges that reduced our income before income 
taxes by $36 million in 2010, $131 million in 2009 and $510 million in 2008. Impairment charges are 
recorded for other-than-temporary declines in value, if, in the asset impairment committee’s judgment, the 
value is not expected to be recouped within a designated recovery period. OTTI losses represent non-cash 
charges to income and are reported as realized investment losses. 
Our investment portfolio managers monitor their assigned portfolios. If a security is trading below book value, 
the portfolio managers undertake additional reviews. Such declines often occur in conjunction with events 

Cincinnati Financial Corporation – 2010 10-K – Page 44 

 
taking place in the overall economy and market, combined with events specific to the industry or operations 
of the issuing organization. Managers review quantitative measurements such as a declining trend in fair 
value, the extent of the fair value decline and the length of time the value of the security has been 
depressed, as well as qualitative measures such as pending events, credit ratings and issuer liquidity. We are 
even more proactive when these declines in valuation are greater than might be anticipated when viewed in 
the context of overall economic and market conditions. We provide information about valuation of our 
invested assets in Item 8, Note 2 of the Consolidated Financial Statements, Page 111. 
All securities valued below 100 percent of book value are reported to the asset impairment committee for 
evaluation. Securities valued between 95 percent and 100 percent of book value are reviewed but not 
monitored separately by the committee.  
When evaluating for OTTI, the committee considers the company’s intent and ability to retain a security for a 
period adequate to recover its cost. Because of the company's financial strength and other factors discussed 
below, management may not impair certain securities even when they are trading below book value.  
When determining OTTI charges for our fixed-maturity portfolio, management places significant emphasis on 
whether issuers of debt are current on contractual payments and whether future contractual amounts are 
likely to be paid. Our fixed maturity invested asset impairment policy states that OTTI is considered to have 
occurred (1) if we intend to sell the impaired fixed maturity security; (2) if it is more likely than not we will be 
required to sell the fixed maturity security before recovery of its amortized cost basis; or (3) the present value 
of the expected cash flows is not sufficient to recover the entire amortized cost basis. If we intend to sell or it 
is more likely than not we will be required to sell, the book value of any such securities is reduced to fair 
value as the new cost basis, and a realized loss is recorded in the quarter in which it is recognized. When we 
believe that full collection of interest and/or principal is not likely, we determine the net present value of 
future cash flows by using the effective interest rate implicit in the security at the date of acquisition as the 
discount rate and compare that amount to the amortized cost and fair value of the security. The difference 
between the net present value of the expected future cash flows and amortized cost of the security is 
considered a credit loss and recognized as a realized loss in the quarter in which it occurred. The difference 
between the fair value and the net present value of the cash flows of the security, the non-credit loss, is 
recognized in other comprehensive income as an unrealized loss.  
When determining OTTI charges for our equity portfolio, our invested asset impairment policy considers 
qualitative and quantitative factors, including facts and circumstances specific to individual securities, asset 
classes, the financial condition of the issuer, changes in dividend payment, the length of time fair value had 
been less than book value, the severity of the decline in fair value below book value, the volatility of the 
security and our ability and intent to hold each position until its forecasted recovery. 
For each of our equity securities in an unrealized loss position at December 31, 2010, we applied the 
objective quantitative and qualitative criteria of our invested asset impairment policy for OTTI. Our long-term 
equity investment philosophy, emphasizing companies with strong indications of paying and growing 
dividends, combined with our strong surplus, liquidity and cash flow, provide us the ability to hold these 
investments through what we believe to be slightly longer recovery periods occasioned by the recession and 
historic levels of market volatility. Based on the individual qualitative and quantitative factors, as discussed 
above, we evaluate and determine an expected recovery period for each security. A change in the condition 
of a security can warrant impairment before the expected recovery period. If the security has not recovered 
cost within the expected recovery period, the security is impaired. 
Securities that have previously been impaired are evaluated based on their adjusted book value and written 
down further, if deemed appropriate. We provide detailed information about securities trading in a 
continuous loss position at year-end 2010 in Item 7A, Application of Asset Impairment Policy, Page 96. 
An other-than-temporary decline in the fair value of a security is recognized in net income as a realized 
investment loss.  
Securities considered to have a temporary decline would be expected to recover their book value, which may 
be at maturity. Under the same accounting treatment as fair value gains, temporary declines (changes in the 
fair value of these securities) are reflected in shareholders’ equity on our balance sheet in accumulated other 
comprehensive income (AOCI), net of tax, and have no impact on net income.

FAIR VALUE MEASUREMENTS 
Valuation of Financial Instruments 
Valuation of financial instruments, primarily securities held in our investment portfolio, is a critical 
component of our year-end financial statement preparation. Fair Value Measurements and Disclosures, 
ASC 820-10, defines fair value as the exit price or the amount that would be (1) received to sell an asset or 
(2) paid to transfer a liability in an orderly transaction between marketplace participants at the measurement 
date. When determining an exit price, we must, whenever possible, rely upon observable market data. Prior 
to the adoption of ASC 820-10, we considered various factors such as liquidity and volatility but primarily 
obtained pricing from various external services, including broker quotes. 
The fair value measurement and disclosure exit price notion requires our valuation also to consider what a 
marketplace participant would pay to buy an asset or receive to assume a liability. Therefore, while we can 
consider pricing data from outside services, we ultimately determine whether the data or inputs used by 
these outside services are observable or unobservable. 
In accordance with ASC 820-10, we have categorized our financial instruments, based on the priority of the 
inputs to the valuation technique, into a three-level fair value hierarchy. The fair value hierarchy gives the 
highest priority to quoted prices in active markets for identical assets or liabilities (Level 1) and the lowest 
priority to unobservable inputs (Level 3). If the inputs used to measure the financial instruments fall within 
different levels of the hierarchy, the categorization is based on the lowest level that is significant to the fair 
value measurement of the instrument. 
Financial assets and liabilities recorded on the Consolidated Balance Sheets are categorized based on the 
inputs to the valuation techniques as described in Item 8, Note 3, Fair Value Measurements, Page 114. 
Level 1 and Level 2 Valuation Techniques 
Over 99 percent of the $11.424 billion of securities in our investment portfolio measured at fair value 
are classified as Level 1 or Level 2. Financial assets that fall within Level 1 and Level 2 are priced according 
to observable data from identical or similar securities that have traded in the marketplace. Also within 
Level 2 are securities that are valued by outside services or brokers where we have evaluated the pricing 
methodology and determined that the inputs are observable. 
Level 3 Valuation Techniques 
Financial assets that fall within the Level 3 hierarchy are valued based upon unobservable market inputs, 
normally because they are not actively traded on a public market. Level 3 corporate fixed-maturity securities 
include certain private placements, small issues, general corporate bonds and medium-term notes. 
Level 3 state, municipal and political subdivisions fixed-maturity securities include various thinly traded 
municipal bonds. Level 3 preferred equities include private and thinly traded preferred securities. 
Pricing for each Level 3 security is based upon inputs that are market driven, including third-party reviews 
provided to the issuer or broker quotes. However, we placed in the Level 3 hierarchy securities for which we 
were unable to obtain the pricing methodology or we could not consider the price provided as binding. 
Pricing for securities classified as Level 3 could not be corroborated by similar securities priced using 
observable inputs. 
Management ultimately determined the pricing for each Level 3 security that we considered to be the 
best exit price valuation. As of December 31, 2010, total Level 3 assets were less than 1 percent of our 
investment portfolio measured at fair value. Broker quotes are obtained for thinly traded securities that 
subsequently fall within the Level 3 hierarchy. We have generally obtained two non-binding quotes from 
brokers and, after evaluating, our investment professionals typically selected the lower quote as the 
fair value. 
EMPLOYEE BENEFIT PENSION PLAN  
We have a defined benefit pension plan that was modified during 2008; refer to Item 8, Note 13 of the 
Consolidated Financial Statements, Page 121, for additional information. Contributions and pension costs 
are developed from annual actuarial valuations. These valuations involve key assumptions including discount 
rates, expected return on plan assets and compensation increase rates, which are updated annually. Any 
adjustments to these assumptions are based on considerations of current market conditions. Therefore, 
changes in the related pension costs or credits may occur in the future due to changes in assumptions.  
Key assumptions used in developing the 2010 net pension obligation for our qualified plan were a 
5.85 percent discount rate and rates of compensation increases ranging from 3.50 percent to 5.50 percent. 
Key assumptions used in developing the 2010 net pension expense for our qualified plan were a 
6.10 percent discount rate, an 8.00 percent expected return on plan assets and rates of compensation 
increases ranging from 4.00 percent to 6.00 percent. See Note 13, Page 121 for additional information 
on assumptions.  

Cincinnati Financial Corporation – 2010 10-K – Page 46 

In 2010, the net pension expense was $12 million. In 2011, we expect the net pension expense to be 
$13 million. 
Holding all other assumptions constant, a 0.5 percentage-point decrease in the discount rate would decrease 
our 2011 income before income taxes by $1 million. A 0.5 percentage point decrease in the expected return 
on plan assets would decrease our 2011 income before income taxes by $1 million. 
The fair value of the plan assets was $30 million less than the accumulated benefit obligation at year-end 
2010 and $42 million less at year-end 2009. The fair value of the plan assets was $62 million less than the 
projected plan benefit obligation at year-end 2010 and $77 million less at year-end 2009. Market conditions 
and interest rates significantly affect future assets and liabilities of the pension plan. On February 1, 2011, 
we contributed $35 million to our qualified plan. 
DEFERRED ACQUISITION COSTS  
We establish a deferred asset for costs that vary with, and are primarily related to, acquiring property 
casualty and life insurance business. These costs are principally agent commissions, premium taxes and 
certain underwriting costs, which are deferred and amortized into net income as premiums are earned. 
Deferred acquisition costs track with the change in premiums. Underlying assumptions are updated 
periodically to reflect actual experience. Changes in the amounts or timing of estimated future profits could 
result in adjustments to the accumulated amortization of these costs. 
For property casualty policies, deferred acquisition costs are amortized over the terms of the policies. We 
assess recoverability of deferred acquisition costs at the segment level, consistent with the ways we acquire, 
service, manage and measure profitability. Our property casualty insurance operations consist of three 
segments, commercial lines, personal lines and excess and surplus lines. For life insurance policies, 
acquisition costs are amortized into income either over the premium-paying period of the policies or the life 
of the policy, depending on the policy type. We analyze our acquisition cost assumptions periodically to 
reflect actual experience; we evaluate our deferred acquisition cost for recoverability; and we regularly 
conduct reviews for potential premium deficiencies or loss recognition. 
CONTINGENT COMMISSION ACCRUAL 
Another significant estimate relates to our accrual for property casualty contingent (profit-sharing) 
commissions. We base the contingent commission accrual estimate on property casualty underwriting 
results. Contingent commissions are paid to agencies using a formula that takes into account agency 
profitability, premium volume and other factors, such as prompt monthly payment of amounts due to the 
company. Due to the complexity of the calculation and the variety of factors that can affect contingent 
commissions for an individual agency, the amount accrued can differ from the actual contingent 
commissions paid. The contingent commission accrual of $77 million in 2010 contributed 2.6 percentage 
points to the property casualty combined ratio. If contingent commissions paid were to vary from that amount 
by 5 percent, it would affect 2011 net income by $3 million (after tax), or 2 cents per share, and the 
combined ratio by approximately 0.1 percentage points. 
SEPARATE ACCOUNTS 
We issue life contracts referred to as bank-owned life insurance policies (BOLI). Based on the specific 
contract provisions, the assets and liabilities for some BOLIs are legally segregated and recorded as assets 
and liabilities of the separate accounts. Other BOLIs are included in the general account. For separate 
account BOLIs, minimum investment returns and account values are guaranteed by the company and also 
include death benefits to beneficiaries of the contract holders.  
Separate account assets are carried at fair value. Separate account liabilities primarily represent the contract 
holders' claims to the related assets and are carried at an amount equal to the contract holders’ account 
value. Generally, investment income and realized investment gains and losses of the separate accounts 
accrue directly to the contract holders and, therefore, are not included in our Consolidated Statements of 
Income. However, each separate account contract includes a negotiated realized gain and loss sharing 
arrangement with the company. This share is transferred from the separate account to our general 
account and is recognized as revenue or expense. In the event that the asset value of contract holders’ 
accounts is projected below the value guaranteed by the company, a liability is established through a charge 
to our earnings.  
For our most significant separate account, written in 1999, realized gains and losses are retained in the 
separate account and are deferred and amortized to the contract holder over a five-year period, subject to 
certain limitations. Upon termination or maturity of this separate account contract, any unamortized deferred 
gains and/or losses will revert to the general account. In the event this separate account holder were to 
exchange the contract for the policy of another carrier in 2011, the account holder would not pay a surrender 
charge. The surrender charge is zero for 2011 and beyond. 

Cincinnati Financial Corporation – 2010 10-K – Page 47 

Life insurance 

At year-end 2010, net unamortized realized losses amounted to $2 million. In accordance with this separate 
account agreement, the investment assets must meet certain criteria established by the regulatory 
authorities to whose jurisdiction the group contract holder is subject. Therefore, sales of investments may be 
mandated to maintain compliance with these regulations, possibly requiring gains or losses to be recorded 
and charged to the general account. Potentially, losses could be material; however, unrealized losses are 
approximately $7 million before tax in the separate account portfolio, which had a book value of $583 million 
at year-end 2010. 
RECENT ACCOUNTING PRONOUNCEMENTS 
Information about recent accounting pronouncements is provided in Item 8, Note 1 of the Consolidated 
Financial Statements, Page 105. We have determined that recent accounting pronouncements have not had 
nor are they expected to have any material impact on our consolidated financial statements. 
RESULTS OF OPERATIONS 
Consolidated financial results primarily reflect the results of our five reporting segments. These segments 
are defined based on financial information we use to evaluate performance and to determine the allocation 
of assets. 
•  Commercial lines property casualty insurance  
•  Personal lines property casualty insurance 
•  Excess and surplus lines property casualty insurance  
• 
• 
We report as Other the non-investment operations of the parent company and its non-insurer subsidiary, 
CFC Investment Company.  
We measure profit or loss for our commercial lines, personal lines and excess and surplus property casualty 
and life insurance segments based upon underwriting results (profit or loss), which represent net earned 
premium less loss and loss expenses and underwriting expenses on a pretax basis. We also frequently 
evaluate results for our consolidated property casualty insurance operations, which is the total of our 
commercial, personal, and excess and surplus insurance results. Underwriting results and segment pretax 
operating income are not substitutes for net income determined in accordance with GAAP. 
For our consolidated property casualty insurance operations as well as the insurance segments, statutory 
accounting data and ratios are key performance indicators that we use to assess business trends and to 
make comparisons to industry results, since GAAP-based industry data generally is not as readily available.  
Investments held by the parent company and the investment portfolios for the insurance subsidiaries are 
managed and reported as the investments segment, separate from the underwriting businesses. Net 
investment income and net realized investment gains and losses for our investment portfolios are discussed 
in the Investment Results of Operations.  
The calculations of segment data are described in more detail in Item 8, Note 18 of the Consolidated 
Financial Statements, Page 127. The following sections review results of operations for each of the five 
segments. Commercial Lines Insurance Results of Operations begins on Page 54, Personal Lines Insurance 
Results of Operations begins on Page 64, Excess and Surplus Lines Insurance Results of Operations begins 
on Page 70, Life Insurance Results of Operations begins on Page 73, and Investment Results of Operations 
begins on Page 75. We begin with an overview of our consolidated property casualty operations.

CONSOLIDATED PROPERTY CASUALTY INSURANCE RESULTS OF OPERATIONS 
Our consolidated property casualty operations grew earned premiums slightly in 2010 and lowered its 
underwriting loss, reversing the lower revenue and deteriorating profitability trends of 2008 and 2009. While 
soft market conditions persisted for commercial lines, our largest operating segment, several profit 
improvement and premium growth initiatives began to be evident in results for 2010.  
In addition to the factors discussed in Commercial Lines, Personal Lines and Excess and Surplus Lines 
Insurance Results of Operations, beginning on Page 54, Page 64 and Page 70, respectively, overall growth 
and profitability for our consolidated property casualty insurance operations were affected by a number of 
common factors. Targeted growth, seeking to grow premiums where we believe profit margins are 
acceptable, has been an area of strategic focus in recent years. Development and use of enhanced 
technology has also been emphasized, helping us to grow premiums as agencies embrace greater ease of 
use of our policy administration software. Better technology also can improve efficiency for agencies and 
associates, helping to lower expenses. Careful expense management, spending more in areas of strategic 
importance and trimming costs in other areas, kept the 2010 expense ratio flat. Slightly lower losses from 
weather-related catastrophes and a slowly recovering economy also benefited our operating results. The 
table below highlights property casualty results of operations, with analysis and discussion in the sections 
that follow.

Performance highlights for consolidated property casualty operations include:  
•  Premiums – Higher 2010 renewal and new business written premiums were driven by growth in our 

personal lines and excess and surplus lines segments. Changes in written and earned premiums over 
the past three years generally reflected intense price competition partially offset by fairly stable policy 
retention rates for renewal business and growth in new business. New business written premiums 
increased in each of the past three years, largely due to the contribution of new agency appointments – 
in both new and existing states of operation; the contribution of our excess and surplus lines business; 
and more competitive personal lines pricing that included net rate increases since late 2009. Other 
written premiums primarily include premiums ceded to our reinsurers as part of our reinsurance 
program. The table below analyzes premium revenue components and trends. Premium trends by 
segment are further discussed beginning on Page 12, Page 15 and Page 16, for the respective property 
casualty segments.

•  Combined ratio – The 2010 combined ratio improved 2.8 percentage points to 101.7 percent, lowering 
the 2009 underwriting loss by more than half. The 1.4 percentage point increase in the ratio for current 
accident year losses and loss expenses was offset by a larger benefit from net favorable reserve 
development on prior accident years and lower catastrophe losses. Components of the combined ratio 
are discussed below, followed by additional discussion by segment.  
Our statutory combined ratio was 101.8 percent in 2010 compared with 104.4 percent in 2009 and 
100.4 percent in 2008. As a comparison, the estimated property casualty industry combined ratio was 
103.0 percent in 2010, 101.2 percent in 2009 and 105.1 percent in 2008.   
Catastrophe losses contributed 5.1 percentage points to the combined ratio in 2010, down 0.6 points 
from 2009. Catastrophe losses in 2008 contributed 6.8 percentage points, the highest catastrophe loss 
ratio for our company since 1991, largely due to Hurricane Ike. Our 10-year historical annual average 
contribution of catastrophe losses to the combined ratio was 4.4 percentage points as of 
December 31, 2010. The following table shows catastrophe losses incurred, net of reinsurance, for the 
past three years, as well as the effect of loss development on prior period catastrophe reserves.

Consolidated Property Casualty Insurance Loss and Loss Expenses 
Loss and loss expenses include both net paid losses and reserve changes for unpaid losses as well as the 
associated loss expenses. Most of the incurred losses and loss expenses shown in the three-year highlights 
table on Page 49 are for the respective current accident years, and reserve development on prior accident 
years is shown separately. Since less than half of our consolidated property casualty current accident year 
incurred losses and loss expenses represents net paid losses, the majority represents reserves for our 
estimate of ultimate losses and loss expenses. These reserves develop over time, and we re-estimate 
previously reported reserves as we learn more about the development of the related claims. The table below 
illustrates that development. For example, the 78.1 percent accident year 2009 loss and loss expense ratio 
reported as of December 31, 2009, developed favorably by 6.5 percentage points to 71.6 percent due to 
settling claims for less than previously estimated, or due to updated reserve estimates for unpaid claims, as 
of December 31, 2010. Accident years 2009 and 2008 have both developed favorably, as indicated by the 
progression over time for the ratios in the table.

Catastrophe loss trends, discussed above, explain some of the accident year loss and loss expenses trend for 
years 2008 through 2010. Catastrophe losses added 5.6 for 2010, 5.9 for 2009 and 6.8 percentage points 
for 2008 to the respective consolidated property casualty accident year loss and loss expense ratios in the 
table above.  
The trend for our current accident year loss and loss expense ratio before catastrophe losses over the past 
three years reflected normal loss cost inflation as well as softer pricing for much of our property casualty 
business that began in 2005 and continued through 2010. Refinements made to the allocation of IBNR 
reserves by accident year, totaling $69 million, contributed 2.3 percentage points to the 2008 ratio. 
Reserve development on prior accident years continued to net to a favorable amount in 2010, as 
$304 million was recognized, similar to $323 million in 2008. During 2009, the $188 million of net favorable 
development recognized was lower, due primarily to unfavorable development of $48 million for our workers’ 
compensation line of business, as discussed in Commercial Lines Insurance Segment Reserves, Page 85.

In 2010, total large losses incurred decreased by $112 million or 16 percent, helping to lower the 
corresponding ratio by 4.0 percentage points. Large loss trends are further analyzed in the segment 
discussion below. Our analysis indicated no unexpected concentration of these losses and reserve increases 
by geographic region, policy inception, agency or field marketing territory. We believe the inherent volatility of 
aggregate loss experience for our portfolio of larger policies is greater than that of our portfolio of smaller 
policies, and we continue to monitor the volatility in addition to general inflationary trends in loss costs. 
Beginning in 2009, we raised the casualty treaty retention to $6 million from $5 million and raised the 
property treaty retention to $5 million from $4 million.

Commission expenses include our profit-sharing, or contingent commissions, which are primarily based on 
the profitability of an agency’s business. The aggregate profit trend for agencies that earn these profit-based 
commissions can differ from the aggregate profit trend for all agencies reflected in our consolidated property 
casualty results. In 2010, lower contingent commissions drove the lower ratio for property casualty 
commission expenses, and higher contingent commissions drove the increase in 2009.  
In 2010, non-commission expenses were up $13 million or 3 percent, primarily due to  a first-quarter 2010 
provision for matters involving prior years and related to Note 16, Commitments and Contingent Liabilities, 
Page 125. The increase outpaced earned premiums, which grew less than 1 percent. In 2009, non-
commission expenses declined $14 million, primarily due to a  change in our pension plan that added 
0.5 percentage points to the 2008 non-commission underwriting expense ratio. 
Discussions below of our property casualty insurance segments provide additional detail about our results.

Performance highlights for the commercial lines segment include:  
•  Premiums – Pricing in the commercial lines marketplace again reflected very strong competition, driving 

modest declines for both renewal and new business premiums. Our commercial lines net written 
premium decrease for 2010 of 1 percent compared favorably with the estimated decline of 2 percent for 
the overall commercial lines industry, similar to the 2009 comparison when our decline of 6 percent was 
slightly better than the decrease estimated for the commercial lines segment of the industry at 
8 percent. We believe our pace for new and renewal business in recent years is consistent with our 
agents’ practice of selecting and retaining accounts with manageable risk characteristics that support 
the lower prevailing prices. We also believe our favorable comparison to the industry in recent years 
reflects our premium growth initiatives and the advantages we achieve through our field focus, which 
provides us with quality intelligence on local market conditions. Our earned premiums declined in 
2010 and 2009, following the pattern of our written premiums.  

•  Combined ratio – For our commercial lines segment, the 2010 combined ratio improved 2.2 percentage 
points to 99.4 percent, and the segment generated a small underwriting profit. Modest increases in the 
ratios for catastrophes and current accident year losses and loss expenses were offset by a larger 
benefit from net favorable reserve development on prior accident years. That larger benefit was 
accounted for almost entirely by our workers’ compensation and commercial casualty lines of business. 
We continue to focus on sound underwriting fundamentals and obtaining adequate premiums for risks 
insured by each individual policy. Predictive analytics for better pricing precision have been used for our 
workers’ compensation line of business since the second half of 2009. We plan to deploy in 2011 similar 
tools for our commercial auto, general liability and commercial property lines.  
The small increase in the 2010 and 2009 ratios for current accident year before catastrophe losses 
largely reflects loss cost trends that outpaced earned premium trends. The ratio increase for 2009 was 
less than it would have been if 2008 had not included approximately $49 million, or 2.1 percentage 
points, from refinements made to the allocation of IBNR reserves by accident year. We discuss factors 
affecting the combined ratio and reserve development by line of business below. 
Our commercial lines statutory combined ratio was 99.6 percent in 2010 compared with 101.8 percent 
in 2009 and 96.6 percent in 2008. By comparison, the estimated industry commercial lines combined 
ratio was 108.5 percent in 2010, 103.0 percent in 2009 and 107.4 percent in 2008. Industry 
commercial lines estimates include mortgage and financial guaranty insurers, which saw a surge in

Due to the highly competitive commercial lines markets of several years, we have focused on leveraging our 
local relationships to benefit from the efforts of our agents and the teams that work with them. We seek to 
maintain appropriate pricing discipline for both new and renewal business as management emphasizes the 
importance of assessing account quality to our agencies and underwriters, for careful decisions on a case-by-
case basis whether to write or renew a policy. Rate credits may be used to retain renewals of quality business 
and to earn new business, but we do so selectively in order to avoid commercial accounts that we believe 
have insufficient profit margins. In recent years we experienced that typically the larger the account, the 
higher the credits needed to write or retain it, with variations by geographic region and class of business. 
In addition to targeting adequate premium per exposure, we also pursue non-pricing means of enhancing 
longer-term profitability. Non-pricing means have included deliberate reviews to assess each risk, determine 
limits of insurance and establish appropriate terms and conditions. We continue to adhere to our 
underwriting guidelines, to re-underwrite books of business with selected agencies and to update policy 
terms and conditions, leveraging the local presence of our field staff. Our field marketing representatives 
continue to underwrite new business and meet with local agencies to reaffirm agreements regarding the 
extent of frontline renewal underwriting that agents will perform. Loss control, machinery and equipment and 
field claims representatives continue to conduct on-site inspections. To assist underwriters, field claims 
representatives prepare full reports on their first-hand observations of risk quality. 
In recent years, both renewal and new business premium volume reflected the effects of the economic 
slowdown in many regions, as exposures declined and policyholders became increasingly focused on 
reducing insurance costs and other expenses. Insured exposures for overall commercial lines were estimated 
to be down somewhat for the year 2010, but appeared to be flattening by the end of the year. For 
commercial accounts, we usually calculate general liability premiums based on sales or payroll volume, while 
we calculate workers’ compensation premiums based on payroll volume. A change in sales or payroll volume 
generally indicates a change in demand for a business’s goods or services, as well as a change in its 
exposure to risk. Policyholders who experience sales or payroll volume changes due to economic factors may 
also have other exposures requiring insurance, such as commercial auto or commercial property, in addition 
to general liability and workers’ compensation. Premium levels for these other types of coverages generally 
are not linked directly to sales or payroll volumes.  
In 2010, we estimated that policyholders with a contractor-related ISO general liability code accounted for 
approximately 33 percent of our general liability premiums, which are included in the commercial casualty 
line of business, and that policyholders with a contractor-related National Council on Compensation 
Insurance Inc. (NCCI) workers’ compensation code accounted for approximately 44 percent of our workers’ 
compensation premiums. The market seeking to insure contractors has been more adversely affected by the 
economic slowdown than some other markets. 
The 2 percent decline in 2010 agency renewal written premiums largely reflects pricing and exposure 
declines, while policy retention rates remained fairly stable. Our headquarters underwriters talk regularly with 
agents about renewal business. Our field teams are available to assist headquarters underwriters by 
conducting inspections and holding renewal review meetings with agency staff. These activities can help 
verify that a commercial account retains the characteristics that caused us to write the business initially. We 
measure average changes in commercial lines renewal pricing as the rate of change in renewal premium for 
the new policy period compared with the premium for the expiring policy period, assuming no change in the 
level of insured exposures or policy coverage between those periods for respective policies. For policies 
renewed during both 2010 and 2009, the typical pricing decline on average was in the low-single-digit range. 
For larger accounts, we typically experienced more significant premium declines and for smaller accounts we 
sometimes saw little if any premium change at renewal. The 2009 average represented an improvement 
from the mid-single-digit range average pricing decline experienced in 2008.  
In addition to pricing pressures, premiums resulting from audits that confirmed or adjusted premiums based 
on initial estimates of policyholder sales and payrolls affected premium trends in recent years. Written 
premiums from audits decreased $29 million and $5 million, respectively, for the years 2010 and 2009, 

Cincinnati Financial Corporation – 2010 10-K – Page 55 

 
         
         
         
            
            
            
          
          
          
         
         
         
              
              
                
         
         
         
while earned premiums from audits decreased $40 million and $26 million. Compared with late 2009 and 
early 2010, premiums from audits by the end of 2010 represented only a slight drag, or unfavorable effect, 
on total commercial lines written and earned premiums, and we expect the effect to become favorable at 
some point in 2011. 
For new business, our field associates are frequently in our agents’ offices helping to judge the quality of 
each account, emphasizing the Cincinnati value proposition, calling on sales prospects with those agents, 
carefully evaluating risk exposure and providing their best quotes. Some of our new business comes from 
accounts that are not new to the agent. We believe these seasoned accounts tend to be priced more 
accurately than business that is less familiar to our agent because it was recently obtained from a competing 
agent. As we appoint new agencies who choose to move accounts to us, we report these accounts as new 
business to us.  
New business premium volume in recent years has been significantly influenced by new agency 
appointments. All agencies newly appointed since the beginning of 2009 generated commercial lines new 
business written premiums of $40 million during 2010, up $26 million from 2009, while all other agencies 
contributed the remaining $249 million, which was down 12 percent.  
Many of the recently appointed agencies are in Texas, which we entered in late 2008, or Colorado, which we 
entered in 2009. Those two states accounted for over 9 percent of the $289 million 2010 new business 
volume. On a net written premium basis, agencies in Texas and Colorado contributed $40 million of 
commercial lines volume during 2010, up $28 million from 2009. The size of the Texas insurance market, 
relative to most other states, represents significant potential for long-term premium growth.  
The table below summarizes the Texas and Colorado agents’ contribution to our commercial lines new 
business and net written premiums. Net written premiums are earned over the term covered by insurance 
policies and are an important leading indicator of earned premium revenue trends.

In both 2010 and 2009, other written premiums had less of a downward effect on commercial lines net 
written premiums compared with the prior year. Written premiums ceded to reinsurers were approximately 
the same for both years. Both 2010 and 2009 had a more favorable adjustment, compared with the prior 
year, for estimated premiums of policies in effect but not yet processed. The adjustment for estimated 
premiums had an immaterial effect on earned premiums. 
Commercial Lines Insurance Loss and Loss Expenses 
Loss and loss expenses include both net paid losses and reserve changes for unpaid losses as well as the 
associated loss expenses. Most of the incurred losses and loss expenses shown in the three-year highlights 
table above on Page 54 are for the respective current accident years, and reserve development on prior 
accident years is shown separately. Since less than half of our consolidated property casualty current 
accident year incurred losses and loss expenses represents net paid losses, the majority represents reserves 
for our estimate of ultimate losses and loss expenses. These reserves develop over time, and we re-estimate 
previously reported reserves as we learn more about the development of the related claims. The table below 
illustrates that development. For example, the 75.5 percent accident year 2009 loss and loss expense ratio 
reported as of December 31, 2009, developed favorably by 8.0 percentage points to 67.5 percent due to 
settling claims for less than previously estimated, or due to updated reserve estimates for unpaid claims, as 
of December 31, 2010. Accident years 2009 and 2008 for the commercial lines segment have both 
developed favorably, as indicated by the progression over time for the ratios in the table.

Catastrophe losses, as discussed in Consolidated Property Casualty Insurance Results of Operations, 
Page 49, explain some of the movement in accident year loss and loss expense ratios among years 2008 
through 2010. Catastrophe losses added 4.7 percentage points for 2010, 3.0 points for 2009 and 4.6 points 
for 2008 to the respective commercial lines accident year loss and loss expense ratios in the table above.  
The trend for our commercial lines current accident year loss and loss expense ratio before catastrophe 
losses over the past three years reflected normal loss cost inflation as well as softer pricing that began in 
2005 and continued through 2010, as discussed above in Commercial Lines Insurance Premiums. In 
addition, previously discussed refinements made to the allocation of IBNR reserves by accident year 
increased the 2008 ratio. 
Commercial lines reserve development on prior accident years continued to net to a favorable amount in 
2010, as $269 million was recognized, similar to $273 million in 2008. During 2009, the $147 million of net 
favorable development recognized was lower, due primarily to unfavorable development of workers’ 
compensation reserves totaling $48 million, including strengthening of reserves by $49 million in first half of 
the year, as discussed in Commercial Lines Insurance Results of Operations, Commercial Lines of Business 
Analysis, Page 58.   
Most of the commercial lines reserve development on prior accident years reported in years 2008 through 
2010 occurred in our commercial casualty line of business. Development by line of business and other 
trends for commercial lines loss and loss expenses and the related ratios are further analyzed in Commercial 
Lines of Business Analysis, beginning on Page 58.

In 2010, total large losses incurred decreased by $115 million or 19 percent, helping to lower the 
corresponding ratio by 4.9 percentage points. The majority of the decrease was for claims related to general 
liability coverages, largely included in our commercial casualty line of business. The 2009 decline of 
$16 million or 3 percent for total large losses incurred was more than offset by a larger decline in commercial 
lines earned premiums, causing an increase in the ratio. Our analysis indicated no unexpected concentration 
of these losses and reserve increases by geographic region, policy inception, agency or field marketing 
territory. We believe the inherent volatility of aggregate loss experience for our portfolio of larger policies is 
greater than that of our portfolio of smaller policies, and we continue to monitor the volatility in addition to 
general inflationary trends in loss costs. In 2009, we raised the casualty treaty retention to $6 million from 
$5 million and raised the property treaty retention to $5 million from $4 million.

Commercial lines commission expenses as a percent of earned premium declined during 2010, primarily due 
to lower agency contingent commissions. Non-commission underwriting expenses rose 2 percent in 2010 but 
were lower than the 2008 level. The 2010 ratio rose primarily due to lower earned premiums.  
Commercial Lines of Business Analysis 
Approximately 95 percent of our commercial lines premiums relate to accounts with coverages from more 
than one of our business lines. As a result, we believe that the commercial lines segment is best measured 
and evaluated on a segment basis. However, we provide line-of-business data to summarize growth and 
profitability trends separately for each line. The accident year loss data provides current estimates of 
incurred loss and loss expenses and corresponding ratios over the most recent three accident years. 
Accident year data classifies losses according to the year in which the corresponding loss events occur, 
regardless of when the losses are actually reported, recorded or paid.  
For 2010, based on the total loss and loss expense ratio, commercial casualty, our largest line of business, 
continued to be highly profitable. Workers’ compensation and specialty packages had 2010 total loss and 
loss expense ratios significantly higher than we desired. As discussed below, we are taking actions to 
improve pricing and reduce loss costs to benefit future profitability trends.

Commercial casualty is our largest line of business and has in recent years maintained a very satisfactory 
total loss and loss expense ratio. The rate of decline in commercial casualty premiums slowed in 2010, 
despite ongoing pressure from market competition. Economic trends showed modest improvement during 
the year, causing corresponding changes in underlying insured exposures, particularly for general liability 
coverages where the premium amount is heavily influenced by economically-driven measures of risk 
exposure such as sales volume. 
The 2010 calendar year total loss and loss expense ratio improved somewhat, largely due to a higher level, 
compared with 2009, of favorable development on prior accident year reserves. Factors contributing to 
the higher level of favorable prior accident year reserve development included a moderation in trend for 
future umbrella coverage payments and less volatility in the trend estimates for future commercial multiple 
peril payments.  
The 2010 current accident year loss and loss expense ratio before catastrophe losses deteriorated by 
3.9 percentage points compared with accident year 2009, reflecting lower pricing per exposure and normal 
loss cost inflation.

Commercial property is our second largest line of business. Net written premiums for 2010 were up, largely 
due to an $8 million or 14 percent increase in new business written premiums.  
The 2010 calendar year total loss and loss expense ratio was higher than the very profitable level of 2009, 
primarily due to higher catastrophe losses and large losses for fires and non-catastrophe weather. 
The 2010 current accident year loss and loss expense ratio before catastrophe losses also was higher, 
compared with accident year 2009, due to higher large losses for fires and non-catastrophe weather, in 
addition to lower pricing per exposure and normal loss cost inflation. In 2011 we plan to improve pricing 
precision for commercial property as we begin using predictive modeling tools. In addition, we have increased 
our loss control staff and are studying methods for improving the effectiveness of conducting property 
inspections for both new and renewal business.

The decline in commercial auto premiums over the three-year period reflected the downward pressure 
exerted by the market on the pricing of commercial accounts. Commercial auto is one of the business lines 
that we renew and price annually, so market trends may be reflected for this line of business sooner than for 
other lines. Commercial auto also experiences pricing pressure because it often represents the largest 
portion of insurance costs for many commercial policyholder accounts.

The calendar year total loss and loss expense ratio improved during 2010 due to a higher amount of 
favorable development on prior accident year reserves. The ratio was at a profitable level for both 
2009 and 2010. 
The 2010 accident year loss and loss expense ratio was up slightly compared with accident year 2009, as a 
lower level of large losses partially offset lower pricing per exposure and higher physical damage losses.

Workers’ compensation net written premiums for 2010 were down $13 million, largely due to an $8 million 
or 17 percent decrease in new business written premiums. Premiums resulting from audits of initially 
recorded premiums, based on policyholder payroll levels, also lowered net written premiums, reflecting the 
slow economy of recent years. Net written premiums declined sharply in 2009, primarily due to economically-
related lower insured exposures and more selective underwriting resulting in the non-renewal of a number of 
policies in our worst pricing tiers.  
Since we pay a lower commission rate on workers’ compensation business, this line has a higher calendar 
year loss and loss expense breakeven point than our other commercial business lines. Nonetheless, the ratio 
was at an unprofitable level in each of the last three years, and management continues to work to improve 
financial performance for this line. During 2009, we began using a predictive modeling tool to improve risk 
selection and pricing adequacy. Predictive modeling increases pricing adequacy and precision so that our 
agents can better compete for the most desirable workers’ compensation business. We also added to our 
staff of loss control field representatives, premium audit field representatives and field claims 
representatives specializing in workers’ compensation risks. In early 2010, we implemented direct reporting 
of workers’ compensation claims, allowing us to quickly obtain detailed information to promptly assign the 
appropriate level of claims handling expertise to each case. Obtaining more information sooner for specific 
claims allows for medical care appropriate to the nature of each injury, benefiting injured workers, employers 
and agents while ultimately lowering overall loss costs. 
The workers’ compensation business line includes our longest tail exposures, making initial estimates of 
accident year loss and loss expenses incurred more uncertain. Due to the lengthy payout period of workers’ 
compensation claims, small shifts in medical cost inflation and payout periods could have a significant effect 
on our potential future liability compared with our current projections. 
The calendar year total loss and loss expense ratio improved during 2010 primarily due to $39 million of 
favorable development on prior accident year reserves. Most of the favorable reserve development was for 
accident year 2009; approximately half of the favorable development was for losses and the other half was 
for loss adjustment expenses related to reserves for our claims staff to settle outstanding claims. In 2009, 
we recognized $48 million in unfavorable reserve development on accident years 2005 and prior as 
discussed below. 
Our workers’ compensation reserve analyses completed during the first half of 2009 indicated that loss 
cost inflation was higher than previously estimated, leading us to make more conservative assumptions 
about future loss cost inflation when estimating loss reserves, thereby significantly increasing losses 
incurred. The higher estimates of loss cost inflation derived from analyses during 2009 affected reserves 

Cincinnati Financial Corporation – 2010 10-K – Page 60 

 
estimated for many prior accident years, resulting in $48 million of net unfavorable development on prior 
accident year reserves.  
The 2010 accident year loss and loss expense ratio of 106.5 percent was down slightly from accident year 
2009 of 108.8 percent estimated as of December 31, 2009. We believe the improvement is due to 
initiatives begun early in 2010 as mentioned above. Reserve development is further discussed in 
Commercial Lines Insurance Segment Reserves, beginning on Page 85.

Specialty packages premiums were up slightly over the three-year period. 
The calendar year and accident year loss and loss expense ratios reflected a high level of catastrophe losses 
for each year in the three-year period. Losses for 2010 also reflected a higher level of large losses for fires 
and non-catastrophe weather, increasing both the calendar year and accident year ratios for 2010. 
In addition, pricing reductions and normal loss cost inflation continued to put upward pressure on the ratios. 
Our adverse loss experience has been primarily driven by our Religious Institutions Program as our other 
specialty programs have generally performed adequately. We are working to improve this program, including 
enhanced pricing precision through predictive models and greater attention as management of the program 
shifts to our Target Markets department. Improved pricing precision and additional loss control actions will be 
used later for the other programs in our Specialty Packages line of business as well.

Surety and executive risk premiums declined in both 2010 and 2009, primarily due to our non-renewal of 
many policies as we improved the quality of the financial institution portion of this book of business.  
Director and officer liability coverage accounted for 59.8 percent of surety and executive risk net written 
premiums in 2010 compared with 60.5 percent in 2009 and 63.0 percent in 2008. We have actively 
managed the potentially high risk of writing director and officer liability by: 
•  Marketing primarily to nonprofit organizations, which accounted for approximately 72 percent of the 
policies and 40 percent of the premium volume for director and officer liability new business written 
in 2010.  

•  Closely monitoring our for-profit policyholders – At year-end 2010, our in-force director and officer liability 
policies provided coverage to 13 non-financial publicly traded companies, including two Fortune 1000 
companies. We also provided this coverage to approximately 500 banks, savings and loans and other 
financial institutions. The majority of these financial institution policyholders are smaller community 
banks, and we believe they have no unusual exposure to credit-market concerns, including subprime 
mortgages. Based on new policy data or information from the most recent policy renewal, only 15 of our 
bank and savings and loan policyholders have assets greater than $2 billion; only 23 have assets from 
$1 billion to $2 billion; and 54 have assets from $500 million to $1 billion.  

•  Writing on a claims-made basis, which normally restricts coverage to losses reported during the 

policy term.  

•  Providing limits no higher than $10 million with facultative or treaty reinsurance in place in 2011 to 

cover losses greater than $6 million.  

The calendar year total loss and loss expense ratio improved during 2010 due to lower losses for accident 
year 2010 that were partially offset by unfavorable development on prior accident year reserves.  
The 2010 accident year loss and loss expense ratio improved compared with accident year 2009 due in part 
to a lower level of large losses. Both the calendar year and current accident year loss and loss expense ratios 
for 2009 were relatively high, primarily due to director and officer large losses from claims related to prior 
lending practices at financial institutions. To address the potential risk inherent in the financial institutions 
book of our surety and executive risk business line moving forward, we continue to work with our agents to 
limit the number of new director and officer policies for financial institutions, in addition to using credit rating 
and other metrics to carefully re-underwrite in-force policies when they are considered for renewal.

Machinery and equipment premiums continued to rise over the three year period, reflecting our superior 
service, including experienced specialist who support agencies in writing this line of business. The calendar 
year and accident year loss and loss expense ratios were low for 2010 and 2009, although they can fluctuate 
substantially due to the relatively small size of this business line.

Commercial Lines Insurance Outlook 
Industrywide commercial lines written premiums are projected to increase less than 1 percent in 2011 with 
the industry statutory combined ratio estimated at approximately 110 percent. As discussed in Item 1, 
Commercial Lines Property Casualty Insurance Segment, Page 12, over the past several years, renewal and 
new business pricing has come under steadily increasing pressure, reinforcing the need for more pricing 
analytics and careful risk selection. While competition remains intense, pricing changes seem to be leveling 
off. Despite challenging market conditions, we believe we can manage our business and execute strategic 
initiatives to offset market pressures to some extent and still profitably grow our commercial lines segment. 
We intend to continue marketing our products to a broad range of business classes with a package 
approach, while improving our pricing precision. We intend to maintain our underwriting selectivity and 
carefully manage our rate levels as well as our programs that seek to accurately match exposures with 
appropriate premiums. We will continue to evaluate each risk individually and to make decisions about rates, 
the use of three-year commercial policies and other policy conditions on a case-by-case basis, even in lines 
and classes of business that are under competitive pressure. Nonetheless, we expect commercial lines 
profitability to remain under pressure in 2011, in part due to small average pricing declines on policies 
renewed during 2010 for which premiums will be earned during 2011. 
In Item 1, Strategic Initiatives, Page 9, we discuss the initiatives we are implementing to achieve our 
corporate performance objectives. We discuss factors influencing future results of our property casualty 
insurance operations in the Executive Summary, Page 36.

Performance highlights for the personal lines segment include:  
•  Premiums – Earned premiums and net written premiums increased in 2010, due to higher renewal and 
new business premiums that reflected improved pricing, including rate changes effective late 2009 for 
most states and representing a net rate increase on average. During 2009, we adjusted pricing in an 
effort to return to consistent profitability in our personal lines segment. Net written premiums grew 
slightly, driven by new business growth that included expansion into new states where we previously 
offered only commercial lines policies. Industry average written premium growth was estimated at 
approximately 3 percent in 2010, up from negative 1 percent in both 2009 and 2008. 

•  Combined ratio – The combined ratio improved 4.1 percentage points in 2010, mostly due to lower 

weather-related catastrophe losses and partly due to improved pricing. The improvement was partially 
offset by a higher underwriting expense ratio and a lower benefit from net favorable reserve development 
on prior accident years. The 2010 level of catastrophe losses, with an 8.1 percent ratio, returned to near 
longer-term historical averages, just 0.4 percentage points below the 10-year average of 8.5 percent. 
The ratio for catastrophe losses in 2009, at 16.1 percent, was approximately twice the 10-year historical 
average but was only 1.6 percentage points higher than 2008. The current accident year loss and loss 
expense ratio, before catastrophe losses, improved slightly during 2010 and reflected better 
underwriting and pricing. For 2009, it trended up slightly, once refinements made to the IBNR reserve 
allocation in 2008 were taken into account. The 2008 ratio included approximately $20 million, or 
2.9 percentage points, from refinements made to the allocation of IBNR reserves by accident year.  
Our personal lines statutory combined ratio was 107.1 percent in 2010, 111.4 percent in 2009 and 
111.6 percent in 2008. By comparison, the estimated industry personal lines combined ratio was 
99.5 percent in 2010, 100.6 percent in 2009 and 103.6 percent in 2008. Our concentration of business 
in areas hard-hit by catastrophe events contributed to recent results that differed from the overall 
industry, an issue we are addressing in part through geographic expansion as noted below. The 
contribution of catastrophe losses to our personal lines statutory combined ratio was 8.1 percentage 
points in 2010, 16.1 percent points in 2009 and 14.5 percentage points in 2008, compared with an 
estimated 5.5, 4.9 and 7.5 percentage points, respectively, for the industry.

Personal lines insurance is a strategic component of our overall relationship with many of our agencies and 
an important component of our agencies’ relationships with their clients. We believe agents recommend 
Cincinnati personal insurance products for their value-oriented clients who seek to balance quality and price 
and who are attracted by our superior claims service and the benefits of our package approach.  
Our personal lines policy retention and new business levels have remained at higher levels following 
introduction in recent years of a limited program of policy credits for personal auto and homeowner pricing in 
most of the states in which we operate. The program provided credits for eligible new and renewal 
policyholders identified as above-average quality risks. Additional pricing and credit changes were 
implemented in early 2009, further improving pricing for the best accounts, which should help us retain and 
attract more of our agents’ preferred business.  
The 7 percent increase in 2010 agency renewal written premiums reflected various rate changes that were 
implemented beginning in October 2009. Increases for the homeowner line of business averaging 
approximately 5 percent, with some individual policy rate increases in the double-digit range, should improve 
loss ratios as the increases are earned. Similar rate changes, with a slightly higher average rate increase, 
were implemented in the fourth quarter of 2010 for states representing the majority of our personal lines 
business. Rate changes for our personal auto line of business implemented during the fourth quarter of 
2010 represented an average rate increase in the low-single-digit range. The 2010 personal auto rate 
changes reflected enhanced pricing precision enabled by the recent deployment of predictive models. 
Predictive modeling tools also influenced policy pricing and various rate changes during 2008 through 
2010 for our homeowner line of business.  
In 2010, our personal lines new business premiums written by our agencies grew 20 percent. We believe the 
main drivers for the growth were more attractive pricing, plus ease of use and efficiency gained by agencies 
from the new version of our Diamond personal lines policy processing system deployed in early 2010. New 
business also rose strongly in 2009 as the number of agency locations writing our personal lines rose by 
133, or 14.4 percent, following an increase of 136 agency locations in 2008. Since early 2008, we have 
worked to improve our geographic diversification by expanding our personal lines operation to several states 
less prone to catastrophes. Seven states where we began writing business or significantly expanded our 
personal lines product offerings and automation capabilities, beginning in 2008, accounted for $13 million of 
the 2009 increase in our personal lines new business written premiums. Those seven states are Arizona, 
Idaho, Maryland, Montana, North Carolina, South Carolina, and Utah. 
For the three-year period, other written premiums, primarily premiums that are ceded to reinsurers and that 
lower our net written premiums, remained relatively stable. Additional premiums ceded to reinsurers to 
reinstate our catastrophe reinsurance treaty contributed $9 million to other written premiums in 2008. 
Personal Lines Insurance Loss and Loss Expenses  
Loss and loss expenses include both net paid losses and reserve changes for unpaid losses as well as the 
associated loss expenses. Most of the incurred losses and loss expenses shown in the three-year 
highlights table above on Page 64 are for the respective current accident years, and reserve development on 
prior accident years is shown separately. Since approximately two-thirds of our personal lines current 
accident year incurred losses and loss expenses represent net paid losses, the remaining one-third 
represents reserves for our estimate of ultimate losses and loss expenses. These reserves develop over time, 
and we re-estimate previously reported reserves as we learn more about the development of the related 
claims. The table below illustrates that development. For example, the 86.3 percent accident year 2009 loss 
and loss expense ratio reported as of December 31, 2009, developed favorably by 1.8 percentage points to 
84.5 percent due to settling claims for less than previously estimated, or due to updated reserve estimates 
for unpaid claims, as of December 31, 2010. Accident years 2009 and 2008 for the personal lines segment 
have both developed favorably, as indicated by the progression over time for the ratios in the table.

Catastrophe losses, as discussed in Consolidated Property Casualty Insurance Results of Operations, 
Page 49, explain some of the movement in accident year loss and loss expense ratios among the years 
2008 through 2010. Catastrophe losses added 8.8 percentage points for 2010, 15.4 points for 2009 and 
14.4 points for 2008 to the respective personal lines accident year loss and loss expense ratios in the table 
above. Catastrophe losses were unusually high during 2009 and 2008, and also are inherently volatile, as 
discussed above and in Consolidated Property Casualty Insurance Results of Operations, Page 49. 
The trend for our personal lines current accident year loss and loss expense ratio before catastrophe losses 
over the past three years reflected normal loss cost inflation, better risk selection and improved pricing, as 
discussed above in Personal Lines Insurance Premiums. Higher non-catastrophe weather-related losses also 
affected trends, particularly for 2008 and 2009, and large losses described below also were a factor. In 
addition, previously discussed refinements made to the allocation of IBNR reserves by accident year 
increased the 2008 ratio. 
Personal lines reserve development on prior accident years continued to net to a favorable amount in 2010, 
as $34 million was recognized, somewhat lower than $40 million in 2009 and $50 million in 2008. Most of 
the personal lines reserve development on prior accident years for years 2008 through 2010 occurred in our 
other personal line of business, primarily for personal umbrella liability coverage. Development by line of 
business and other trends for personal lines loss and loss expenses and the related ratios are further 
analyzed in Personal Lines of Business Analysis, beginning on Page 67, and in Personal Lines Insurance 
Segment Reserves, Page 87.

In 2010, total large losses incurred decreased by $12 million or 13 percent, helping to lower the 
corresponding ratio by 2.1 percentage points. The majority of the decrease was for claims related to our 
personal auto line of business. In 2009 the total large losses incurred ratio was higher than it was in 2008, 
primarily due to more homeowner fire losses. Our analysis indicated no unexpected concentration of these 
losses and reserve increases by risk category, geographic region, policy inception, agency or field marketing 
territory. We believe the inherent volatility of aggregate loss experience for our portfolio of larger policies is 
greater than that of our portfolio of smaller policies, and we continue to monitor the volatility in addition to 
general inflationary trends in loss costs.

Personal lines commission expense as a percent of earned premium increased slightly in 2010 and 
2009, primarily due to higher agency contingent commissions.   

Cincinnati Financial Corporation – 2010 10-K – Page 66 

 
 
Other underwriting expenses grew $17 million or 22 percent, primarily due to a first-quarter 2010 provision 
for matters involving prior years and related to Note 16, Commitments and Contingent Liabilities, Page 125. 
They declined in 2009 primarily due to lower depreciation expense on previously capitalized software 
expenditures. An unusual expense of $3 million due to a pension charge was included in the 2008 ratio. 
Personal Lines of Business Analysis 
We prefer to write personal lines coverages within accounts that include both auto and homeowner 
coverages as well as coverages from the other personal business line. As a result, we believe that the 
personal lines segment is best measured and evaluated on a segment basis. However, we provide 
line-of-business data to summarize growth and profitability trends separately for each line. The accident year 
loss data provides current estimates of incurred loss and loss expenses and corresponding ratios over the 
most recent three accident years. Accident year data classifies losses according to the year in which the 
corresponding loss events occur, regardless of when the losses are actually reported, recorded or paid.  
For 2010, the homeowner line of business had a total loss and loss expense ratio significantly higher than 
desired. As discussed below, we are taking actions to improve pricing and reduce loss costs that we expect to 
benefit future profitability trends.

Net written premiums for personal auto increased significantly in 2010, in part due to strong new 
business growth. 
The calendar year total loss and loss expense ratio rose slightly over the three-year period. In recent years, 
we have seen generally higher costs for liability claims, including severe injuries, and we have sought rate 
increases for liability coverages that partially offset price decreases for physical damage coverages. Pricing 
precision is being improved through use of the recently deployed predictive modeling tool. In addition to using 
the tool as part of rate changes implemented in the fourth quarter of 2010, we expect another round of rate 
changes, representing another net increase in rates on average, effective late 2011.  
The 2010 current accident year loss and loss expense ratio before catastrophe losses deteriorated slightly 
compared with accident year 2009, primarily due to earned pricing changes.

Net written premiums for homeowner increased significantly in 2010, in part due to strong new business 
growth. Premiums ceded for reinsurance, which reduce premium revenue, were $18 million in 2010, 
$22 million in 2009, and $26 million in 2008, including a 2008 reinstatement premium of $8 million. The 
pricing changes of the past several years have had a positive effect on policyholder retention and new 
business activity. We continue to monitor and modify selected rates and credits to address our competitive 
position and to achieve long-term profitability. Implementation of predictive modeling has provided additional 
pricing points to target profitability. Various rate changes were implemented in both late October 2010 and 
2009, including rate increases that respond in part to weather-related loss trends as well as other trends in 
loss costs. The 2009 increases for the homeowner line of business averaged approximately 6 percent in 
affected states and 5 percent overall, although some individual policies experienced renewal increases in the 
double-digit range. The average effect of the 2010 rate changes were approximately the same as 2009 and 
should lower loss ratios as the rate increases are earned. We also continue our gradual geographic 
diversification into states less prone to catastrophe losses, which we believe will reduce variability in the long-
term future catastrophe loss ratio. These actions are important steps we are taking to improve homeowner 
results. 
The calendar year total loss and loss expense ratio over the past three years fluctuated with catastrophe 
losses, non-catastrophe weather-related losses and other large losses. A $5 million increase in 2010 large 
losses, compared with 2009, contributed 1.7 percentage points to the homeowner loss ratio. The 2010 
catastrophe loss effect of 17.9 percentage points returned to a level near historical averages. In 2008 and 
2009, our catastrophe loss ratio averaged 34.5 percent, compared with a 10-year average through 2007 of 
17.4 percent.  
The current accident year loss and loss expense ratio before catastrophe losses remained high in 2010, in 
part due to the same non-catastrophe weather related losses and other large losses that affected the 
calendar year result.

Other personal premiums increased in 2010 and 2009, generally tracking with the growth in our personal 
auto and homeowner lines before the effects of reinsurance. Most of our other personal coverages are 
endorsed to homeowner or auto policies.  
The calendar year and accident year loss and loss expense ratio for other personal continued to improve in 
2010 and has been at a very profitable level the past two years. Reserve development on prior accident 
years can fluctuate significantly for this business line because personal umbrella liability coverage is a major 
component of other personal losses.  
Personal Lines Insurance Outlook 
A.M. Best projects industrywide personal lines written premiums may rise approximately 3 percent in 2011, 
with an industry statutory combined ratio estimated at 98.5 percent. With our improvement in new business 
levels and our strong policy retention rate, along with rate increases effected in late 2010, we expect our 
growth rate to be higher than the industry projection for 2011. In Item 1, Strategic Initiatives, Page 9, we 
discuss the initiatives we are implementing to address the unsatisfactory performance of our personal lines 
segment, in particular the homeowner line of business. We also describe steps to enhance our response to 
the changing marketplace. Our personal lines pricing and loss activity are at levels that could put 
achievement of our corporate financial objectives at risk if those trends continue. We discuss our overall 
outlook for our property casualty insurance operations in the Executive Summary, Page 36.

Performance highlights for the excess and surplus lines segment include:  
•  Premiums – Higher earned premiums in 2010 reflected very strong net written premium growth during 

2009, the second full year of operations for our excess and surplus lines segment. Net written premiums 
grew in 2010 primarily due to more initial opportunities to renew accounts that were written for the first 
time as new business during the previous year. The 2010 volume of those initial opportunities to renew 
nearly doubled the volume of 2009 because new business written premiums in 2009 approximately 
doubled new business premiums written in 2008. New business written premiums grew modestly in 
2010, at a much slower rate than in 2009, partly due to increased competition in the excess and surplus 
lines market, including standard market companies writing policies for risks that were formerly insurable 
only in the excess and surplus lines market.  

•  Combined ratio – The combined ratio improved in 2010, primarily due to lower underwriting expenses. 

The total loss and loss expense ratio increased primarily due to higher large losses, claims exceeding 
$250,000 of insured loss, that outpaced growth in earned premiums.

The $19 million increase in renewal premiums in 2010 was primarily a result of the opportunity to renew 
more policies that represented new business in 2009, when new business written premiums grew by 
$18 million. Renewal pricing changes also accounted for some of the increase, as our excess and surplus 
lines policies averaged estimated price increases that were flat to slightly up in the second half of 2010. We 
measure average changes in excess and surplus lines renewal pricing as the rate of change in renewal 
premium for the new policy period compared with the premium for the expiring policy period, assuming no 
change in the level of insured exposures or policy coverage between those periods for respective policies.  
New business written premium growth in 2009 was largely a result of introducing new coverages, and also 
increased understanding by agencies representing The Cincinnati Insurance Companies of competitive 
advantages described in Excess and Surplus Lines Property Casualty Insurance Segment, Page 16. For most

of 2008, only general liability coverages were available. In late 2008, property and professional liability 
coverages were first offered, followed by excess liability in late 2009.  
Other written premiums are primarily premiums that are ceded to reinsurers and that lower our net written 
premiums. Changes in ceded premium volume tend to follow a pattern similar to changes in the total of 
renewal and new business written premiums.  
Competition for new business increased during 2010 as we observed more instances of business being 
written by standard market commercial lines insurers seeking additional growth opportunities. In many cases 
we saw policy terms and conditions being offered that were less restrictive than those we observed in the 
past for similar risks, without a corresponding premium for the broadened insurance coverage. As a result, 
we declined to write many of those new business and some renewal business opportunities, leading to a 
significantly slower rate of new business growth for 2010 at 9 percent compared with 129 percent in 2009. 
Excess and Surplus Lines Loss and Loss Expenses 
Loss and loss expenses include both net paid losses and reserve changes for unpaid losses as well as the 
associated loss expenses. Most of the incurred losses and loss expenses shown in the three-year highlights 
table above on Page 70 are for the respective current accident years, and reserve development on prior 
accident years is shown separately. Since less than 20 percent of our 2010 excess and surplus lines current 
accident year incurred losses and loss expenses represents net paid losses, a large majority represents 
reserves for our estimate of ultimate losses and loss expenses. These reserves develop over time, and we re-
estimate previously reported reserves as we learn more about the development of the related claims. The 
table below illustrates that development. For example, the 75.6 percent accident year 2009 loss and loss 
expense ratio reported as of December 31, 2009, developed favorably by 2.1 percentage points to 73.5 
percent due to settling claims for less than previously estimated, or due to updated reserve estimates for 
unpaid claims, as of December 31, 2010. Accident years 2009 and 2008 for the excess and surplus lines 
segment have both developed favorably, as indicated by the progression over time for the ratios in the table.

through 2010. Catastrophe losses added 1.2 percentage points for 2010, 0.2 for 2009 and 0.4 percentage 
points for 2008 to the respective excess and surplus lines accident year loss and loss expense ratios in the 
table above.  
The 2010 increase of 8.4 percentage points in the current accident year loss and loss expense ratio before 
catastrophe losses was driven by higher large losses. New losses of $250,000 or more per claim totaled 
$12 million in 2010, compared with less than $1 million in 2009, and accounted for 23.5 percentage points 
of the ratio. No unexpected concentration of these losses was indicated from our analysis by risk category, 
geographic region, policy inception, agency or field marketing territory.  
Our first excess and surplus lines policies were written in 2008 and reserves for estimated unpaid losses and 
loss expenses were $5 million as of December 31, 2008, for losses that occurred in 2008. As of December 
31, 2010, an estimated $2 million remained unpaid for those same loss events that occurred in 2008. Due 
to the limited history of settled claims for our excess and surplus lines business it is difficult to draw 
meaningful inferences about claim settlement patterns or trends in loss and loss expense experience based 
on data in the table above.  
Excess and surplus lines reserve development on prior accident years netted to a favorable amount in 2010, 
$1 million, resulting in a loss and loss expenses ratio effect similar to 2009. Development trends are further 
analyzed in Excess and Surplus Lines Insurance Segment Reserves, Page 89. 
We believe the adequacy of loss and loss expenses reserves for our excess and surplus lines business is 
strong. We establish case reserves in a manner consistent with standard lines coverages, despite the more 
restrictive terms and conditions for excess and surplus lines policies.

Excess and surplus lines commission expense at 16.5 percent of earned premiums for 2010 is expected to 
remain near that level in the future.  
Non-commission underwriting expenses declined in 2010 primarily due to the reduction of various start-up 
costs during 2008 and 2009 as our excess and surplus lines began operations in 2008. The primary 
category of expense reduction was development costs for our rating and policy administration system.  
Excess and Surplus Lines Outlook 
The general trends of 2010 for the excess and surplus lines markets are expected to continue in 2011, 
according to several industry reports. Competition is expected to remain strong, in part due to standard 
market insurance companies insuring businesses that previously were written by excess and surplus lines 
insurers. Soft market conditions for commercial lines business overall is the driver of this trend, and industry 
observers generally expect little change in the foreseeable future. The slowly recovering U.S. economy, 
another major factor in demand for insurance products, is also expected to contribute to modestly declining 
or relatively flat premium volume during 2011 for the excess and surplus lines industry. 
Industry reports suggest that opportunities for managing profitability and growth exist through greater use of 
technology. Technology and data are also being used by excess and surplus lines insurance companies to 
identify new exposures in emerging businesses that need insurance protection or other value-added services. 
Our strategy of providing superior service is expected to continue to grow our excess and surplus lines 
segment and achieve profitability despite challenging market conditions. We intend to continue carefully 
selecting and pricing risks, providing prompt delivery of insurance quotes and policies and outstanding 
claims and loss control service from local field representatives who also handle the standard lines business 
for their assigned agencies. These local representatives are supported by headquarters underwriters and 
claims managers who specialize in excess and surplus lines.

Performance highlights for the life insurance segment include:  
•  Revenues – Driven by higher term life insurance premiums, earned premiums have grown at a double-

digit rate the past two years. Gross in-force policy face amounts increased to $74.124 billion at year-end 
2010 from $69.815 billion at year-end 2009 and $65.888 billion at year-end 2008. 

•  Profitability – The life insurance segment frequently reports only a small profit or loss because most of its 

investment income is included in investment segment results. We include only investment income 
credited to contract holders (interest assumed in life insurance policy reserve calculations) in life 
insurance segment results. The segment reported a $7 million profit in 2010.

We market term, whole and universal life products, fixed annuities and disability income products. 
In addition, we offer term, whole and universal life and disability insurance to employees at their worksite. 
These products provide our property casualty agency force with excellent cross-serving opportunities for both 
commercial and personal accounts. 
Earned premiums increased in 2010 largely because of growth in our term and universal life insurance 
business. Earned premiums from term insurance grew $10 million, or 12 percent, and earned premiums 
from universal life insurance grew $7 million, or 25 percent. 
Separate account investment management fee income contributed $1 million to total revenue in 2010, 
compared with less than $1 million contribution in 2009 and $2 million in 2008. These fees increased 
primarily because of the net realized capital gain and loss sharing agreement between the separate account 
and the general account. 
Over the past several years, we have worked to maintain a portfolio of simple, yet competitive products, 
primarily under the LifeHorizons banner. Our product development efforts emphasize death benefit 
protection and guarantees. Distribution expansion within our property casualty insurance agencies remains 
a high priority. In the past several years, we have added life field marketing representatives for the western, 
southeastern and northeastern states. Our 31 life field marketing representatives work in partnership with 
our 117 property casualty field marketing representatives. Approximately 69 percent of our term and 
other life insurance product premiums were generated through our property casualty insurance 
agency relationships. 
Life Insurance Profitability 
Although we exclude most of our life insurance company investment income from investment 
segment results, we recognize that assets under management, capital appreciation and investment 
income are integral to evaluation of the success of the life insurance segment because of the long 
duration of life products. On a basis that includes investment income and realized gains or losses from 
life insurance-related invested assets, the life insurance company reported a net profit of $39 million in 
2010, compared with a net profit of $22 million in 2009 and a net loss of $19 million in 2008. The life 
insurance company portfolio had after-tax net realized investment gains of $2 million in 2010, compared 
with after-tax net realized investment losses of $13 million in 2009, which included $15 million in OTTI 
charges. Net realized investment losses were $58 million in 2008, including $66 million in OTTI charges. 
Realized investment gains and losses are discussed under Investment Results of Operations, Page 75.

Life segment expenses consist principally of:  
•  Contract holders’ benefits incurred, related to traditional life and interest-sensitive products, accounted 

for 73.6 percent of 2010 total benefits and expenses compared with 76.4 percent in 2009 and 
75.7 percent in 2008. Total contract holders’ benefits rose due to net death claims that increased but 
remained within our range of pricing expectations. 

•  Operating expenses incurred, net of deferred acquisition costs, accounted for 26.4 percent of 2010 total 
benefits and expenses compared with 23.6 percent in 2009 and 24.3 percent in 2008. Unlocking of 
actuarial assumptions for our universal life contracts was the primary reason for increased operating 
expenses in 2010. Expenses in 2010 were also up from increased commissions due to growth in term 
life insurance and fixed annuities. 

Life segment profitability depends largely on premium levels, the adequacy of product pricing, underwriting 
skill and operating efficiencies. Life segment results include only investment interest credited to contract 
holders (interest assumed in life insurance policy reserve calculations). The remaining investment income is 
reported in the investment segment results. The life investment portfolio is managed to earn target spreads 
between earned investment rates on general account assets and rates credited to policyholders. We consider 
the value of assets under management and investment income for the life investment portfolio as key 
performance indicators for the life insurance segment. 
We seek to maintain a competitive advantage with respect to benefits paid and reserve increases by 
consistently achieving better than average claims experience due to skilled underwriting. Commissions paid 
by the life insurance operation are on par with industry averages.  
During the past several years, we have invested in imaging and workflow technology and have significantly 
improved application processing. We have achieved process efficiencies while improving our service. These 
efficiencies have played a significant role in cost containment and in our ability to increase total premiums 
and policy count over the past 10 years with minimal headcount additions. 
Life Insurance Outlook 
During 2010, the life insurance market continued to stabilize from the turmoil it experienced during the 
financial crisis. Of particular interest to us, 2010 saw decreased rate volatility for term insurance as the cost 
of reserve financing moderated, albeit at rates substantially higher than before the financial crisis. This 
higher cost of reserve financing has led a number of large term writers to replace their term portfolios with 
term-like universal life products. These companies have sacrificed a simple design and the high redundant 
reserve requirement with a much more complex design and a lower reserve requirement. We believe this 
offers us a competitive advantage, and we expect to see continued growth in our term business because of 
our commitment to offering our distribution the most straight-forward products possible, at a reliable and 
competitive rate. 
Our property casualty agencies remain the main distribution system for our life insurance segment, and we 
continue to emphasize securing an increasing share of the life insurance premium produced by these 
agencies. While other life insurers continue to expand nontraditional distribution channels such as direct 
sales, we intend to market through agencies affiliated with our property casualty insurance operations or 
independent life-only agencies. In 2010, our property casualty agencies produced 69 percent and our 
life-only agencies 31 percent of our life insurance premium. Term insurance continues to fit well with the 
sales goals of both our property casualty and life-only agencies and remains our largest product line. We 
continue to emphasize the cross-serving opportunities of our worksite products for our property casualty 
agencies’ commercial accounts, and in 2010 we introduced a new worksite term product with a return of 
premium feature. Also in 2010, we introduced a second-to-die universal life product. We believe this product 
helps satisfy an important need that is heightened by an aging boomer population and a fluctuating federal 
estate tax situation. 
We expect annuity sales to moderate somewhat in 2011 as we introduce a new product with a lower 
guaranteed rate of interest. Such a product affords us more protection during prolonged periods of low 
interest rates. New annuity suitability regulations also are a headwind on annuity sales due to the added 
burden on the agent and the resulting increased acquisition costs. 
We made good progress in improving our operational technology in 2010. We remain on track to complete a 
major administration system consolidation project in 2011. Online illustrations were introduced and are 
already contributing to savings. Finally, we have other initiatives underway that will make it easier for our 
agents to do business with us, from flexible compensation arrangements to electronic applications. We fully 
expect all of these initiatives to contribute additional revenue and/or reduced expenses in 2012 and beyond.

The investment segment contributes investment income and realized gains and losses to results of 
operations. Investments provide our primary source of pretax and after-tax profits.  
• 

Investment income – Pretax investment income increased 3 percent in 2010, primarily because of 
additional net purchases in our fixed-maturity portfolio that offset declining yields. Pretax investment 
income declined 7 percent in 2009, primarily because of prior year dividend cuts in our common stock 
portfolio. After-tax investment income increased 2 percent in 2010 compared with a decrease of 
11 percent in 2009. The steeper decline in 2009 after-tax investment income, compared with the pretax 
basis, was primarily due to a change in mix of investment income as dividends have tax-advantages 
relative to interest on corporate bonds. 

•  Realized investment gains and losses – We reported realized investment gains in all three years, largely 

due to investment sales that were discretionary in timing and amount. Those sales were somewhat offset 
by OTTI charges. The $510 million impairment for the write-down of 126 securities in 2008 largely offset 
gains from investment sales. 

Investment Income 
The primary drivers of investment income were: 
• 

Interest income rose 5 percent in 2010 primarily due to investing our typical allocation of net cash flow 
from operations in fixed-maturity securities. It increased significantly in 2009 as we increased our 
allocation of investments to fixed-maturity securities.  

•  Dividend income declined 1 percent in 2010 after declining 51 percent in 2009. In early 2009, we 

reduced the size of our preferred stock portfolio, which generally provides higher yields, in response to 
the market conditions related to the banking crisis. During 2008, we reduced the size of our common 
stock portfolio by more than 50 percent in response to actual or anticipated dividend reductions as well 
as for the implementation of a risk management program.  

In 2010, we continued to invest available cash flow in both fixed income and equity securities in a manner 
that we believe balances current income needs with longer-term invested assets growth goals.

Net Realized Investment Gains and Losses 
Net realized investment gains and losses are made up of realized investment gains and losses on the sale of 
securities, changes in the valuation of embedded derivatives within certain convertible securities and OTTI 
charges. These three areas are discussed below. 
Investment gains or losses are recognized upon the sales of investments or as otherwise required under 
GAAP. The timing of realized gains or losses from sales can have a material effect on results in any given 
period. However, such gains or losses usually have little, if any, effect on total shareholders’ equity because 
most equity and fixed maturity investments are carried at fair value, with the unrealized gain or loss included 
as a component of other comprehensive income. At year-end 2010, the fixed maturities fair value was 
106.3 percent of book value compared with 104.5 percent at year-end 2009. 
Realized Investment Gains and Losses  
As appropriate, we buy, hold or sell both fixed-maturity and equity securities on an ongoing basis to help 
achieve our portfolio objectives. Pretax realized investment gains in the past three years largely were due to 
the sale of equity holdings. 
Net realized investment gains and losses totaling $185 million for the year ended December 31, 2010, 
reflected: 
•  $174 million in realized gains from equity sales, including $128 million from the sale of Verisk Analytics 

Inc. (NYSE: VRSK).  

•  $13 million in net gains from fixed-maturity sales and calls. 
•  $10 million in gains from changes in fair value of securities with embedded derivatives. 
•  $36 million in OTTI charges to write down holdings of equities and fixed maturities. 
The $13 million in net gains from fixed-maturity sales included a $1 million gain in short-term investments 
due to the final receipt from the Reserve Primary Fund that exceeded the impaired basis. The net gains also 
included $12 million in losses due to sales of all of the remaining holdings of collateralized mortgage 
obligations, which occurred during the first quarter of 2010. 
The $440 million net realized investment gain in 2009, was primarily due to $624 million from sales of 
various equity holdings, including Pfizer Inc. (NYSE: PFE), Exxon Mobil Corporation (NYSE: XOM), The Procter 
& Gamble Company (NYSE: PG), Fifth Third Bancorp (NASDAQ: FITB), and Piedmont Natural Gas Company 
Inc. (NYSE: PNY). Realized losses of $162 million from the sale of several equity securities partially offset 
realized investment gains. 
In 2008, most of the gain was due to sales of holdings of common and preferred stocks of financial services 
issuers, to reduce our historical weighting in financial sector securities. The majority of these holdings were 
sold following reductions or elimination of their cash dividends to shareholders. Because of our low cost 
basis, we were able to record gains on many of these sales despite the decline in overall stock market values 
during 2008.  
We generally purchase fixed income securities with the intention to hold until maturity. Securities that no 
longer meet our investment criteria, usually due to a change in credit fundamentals, are divested. 
Change in the Valuation of Securities with Embedded Derivatives  
We have a small portfolio of convertible preferred stocks and bonds, which have an embedded derivative 
component. In 2010 we recorded $10 million in fair value realized gains compared with $27 million in 
2009 and a $38 million fair value decline for 2008. These changes in fair value were due to the application 
of ASC 815-15-25, which allows us to account for the entire hybrid financial instrument at fair value, with 
changes recognized in realized investment gains and losses. The changes in fair values are recognized in net 
income in the period they occur. See the discussion of Derivative Financial Instruments and Hedging 
Activities in Item 8, Note 1 of the Consolidated Financial Statements, Page 105, for details on the accounting 
for convertible security embedded options.  
Other-than-temporary Impairment Charges 
In 2010, we recorded $36 million in write-downs of 15 securities that we deemed had experienced an 
other-than-temporary decline in fair value compared with $131 million for 50 securities in 2009 and 
$510 million for 126 securities in 2008. The factors we consider when evaluating impairments are discussed 
in Critical Accounting Estimates, Asset Impairment, Page 44. The OTTI charges in 2010 were less than 
1 percent of our investment portfolio at year-end compared with 1 percent for 2009 and 5 percent for 2008. 
OTTI charges also include unrealized losses of holdings that we intend to sell but have not yet completed 
a transaction.

The decrease in OTTI charges for both 2010 and 2009 was largely due to the improvement in values as asset 
markets rebounded. The higher level of OTTI charges in 2008 was largely due to write-downs of holdings of 

Cincinnati Financial Corporation – 2010 10-K – Page 77 

 
 
bonds and common and preferred stocks of financial services issuers, reflecting our historical weighting in 
this sector and the decline in overall stock market values during 2008.  
Investments Outlook  
We continue to focus on portfolio strategies to balance near-term income generation and long-term book 
value growth. In 2011, we expect to continue to allocate a portion of cash available for investment to equity 
securities, taking into consideration corporate liquidity and income requirements, as well as insurance 
department regulations and rating agency comments. We discuss our portfolio strategies in Item 1, 
Investments Segment, Page 19.  
We believe that a weak or prolonged recovery from current economic conditions could heighten the risk of 
renewed pressure on securities markets, which could lead to additional OTTI charges. Our asset impairment 
committee continues to monitor the investment portfolio. The current asset impairment policy is described in 
Critical Accounting Estimates, Asset Impairment, Page 44.  
OTHER 
Revenues in 2010 for our Other businesses nearly equaled 2009. Other includes non-investment operations 
of the parent company and its subsidiary, CFC Investment Company, and former subsidiary CinFin Capital 
Management Company. Losses before income taxes for Other were largely driven by interest expense from 
debt of the parent company.

TAXES 
We had $124 million of income tax expense in 2010 compared with $150 million in 2009 and $111 million 
in 2008. The effective tax rate for 2010 was 24.8 percent compared with 25.7 percent in 2009 and 
20.7 percent in 2008.  
The change in our effective tax rate was primarily due to changes in pretax income from underwriting 
results, changes in investment income and the amount of realized investment gains and losses. Changes to 
tax-exempt interest and the dividend received deduction in the current year compared with prior years also 
contributed to the change. 
Historically, we have pursued a strategy of investing some portion of cash flow in tax-advantaged 
fixed-maturity and equity securities to minimize our overall tax liability and maximize after-tax earnings. See 
Tax-Exempt Fixed Maturities, Page 21 for further discussion on municipal bond purchases in our 
fixed-maturity investment portfolio. For our insurance subsidiaries, approximately 85 percent of income from 
tax-advantaged fixed-maturity investments is exempt from federal tax. Our non-insurance companies own an 
immaterial amount of tax-advantaged fixed-maturity investments. For our insurance subsidiaries, the 
dividend received deduction, after the dividend proration of the 1986 Tax Reform Act, exempts approximately 
60 percent of dividends from qualified equities from federal tax. For our non-insurance subsidiaries, the 
dividend received deduction exempts 70 percent of dividends from qualified equities. Details about our 
effective tax rate are found on Note 11, Income Taxes, Page 120. 
LIQUIDITY AND CAPITAL RESOURCES 
We seek to maintain prudent levels of liquidity and financial strength for the protection of our policyholders, 
creditors and shareholders. We manage liquidity at two levels to meet the short- and long-term cash 
requirements of business obligations and growth needs. The first is the liquidity of the parent company. The 
second is the liquidity of our insurance subsidiary. The management of liquidity at both levels is essential 
because each has different funding needs and sources, and each is subject to certain regulatory guidelines 
and requirements.

Parent Company Liquidity  
The parent company’s primary means of meeting liquidity requirements are dividends from our insurance 
subsidiary, investment income and sale proceeds from investments held at the parent company level. The 
parent company’s primary contractual obligations are interest and principal payments on long- and 
short-term debt as described under Contractual Obligations, Page 81. Other uses of parent company cash 
include dividends to shareholders, common stock repurchases and general operating expenses described 
under Other Commitments, Page 81. As of December 31, 2010, the parent company had $1.042 billion in 
cash and marketable securities, providing strong liquidity to fund uses of cash. 
The table below shows a summary, by the direct method, of the major sources and uses of liquidity by the 
parent company. Dividends received in 2010 from our insurance subsidiary returned to a level near the 
average of recent years. No dividends were received from our insurance subsidiary in 2009, in order to 
maintain strong statutory surplus and financial strength ratings. We expect sources of liquidity to increase in 
2011 and beyond, primarily from improved profitability from our property casualty operations, funding a 
potentially larger dividend to the parent company. The majority of expenditures for the parent company have 
been consistent during the last three years, and we expect future expenditures to remain fairly stable. Share 
repurchases are discretionary, depending on cash availability and capital management decisions.

Insurance Subsidiary Liquidity 
Our insurance subsidiary’s primary means of meeting liquidity requirements are collection of premiums, 
investment income, and sale proceeds from investments held at the subsidiary level. Property casualty 
insurance premiums generally are received before losses are paid under the policies purchased with those 
premiums. Our insurance subsidiary’s expenditures are property casualty loss and loss expenses, 
commissions, salaries and other ongoing operating expenses. Over the past three years, cash receipts from 
property casualty along with investment income, have been more than sufficient to pay claims and operating 
expenses. Excess cash flow was partially used to pay dividends to the parent company. We are not aware of 
any known trends that would materially change historical cash flow results. We discuss the factors that 
affected insurance operations in Commercial Lines and Personal Lines Insurance Results of Operations, 
Page 54 and Page 64.  
This table shows a summary of operating cash flow for property casualty insurance (direct method):

Additional Sources of Liquidity 
Investment income is a primary source of liquidity for both the parent company and our insurance subsidiary 
operations. For both, cash in excess of operating requirements and dividends are invested in fixed-maturity 
and equity securities. Equity securities provide the potential for future increases in dividend income and for 
capital appreciation. In Item 1, Investments Segment, Page 19, we discuss our investment strategy, portfolio 
allocation and quality.  
Income from our investments is the most important investment contribution to cash flow. While we have 
never sold investments to make claim payments, the sale of investments could provide an additional source 
of liquidity at either the parent company or insurance subsidiary level, if required, although we follow a buy-
and-hold investment philosophy, seeking to compound cash flows over the long-term. In addition to possible 
sales of investments, proceeds of call or maturities of fixed maturities also can provide liquidity. During the 
next five years, $2.804 billion, or 35.4 percent, of our fixed-maturity portfolio will mature. At year-end 2010, 
total unrealized gains in the investment portfolio, before deferred income taxes, were $1.250 billion. Further, 

Cincinnati Financial Corporation – 2010 10-K – Page 79 

 
 
financial resources of the parent company also could be made available to our insurance subsidiaries, if 
circumstances required. This flexibility would include our ability to access the capital markets and short-term 
bank borrowings.  
We had $790 million of long-term debt and $49 million in borrowings on our short-term lines of credit at 
year-end 2010. We generally have minimized our reliance on debt financing although we may use lines of 
credit to fund short-term cash needs.  
Long-Term Debt 
We provide details of our three long-term notes in Item 8, Note 8 of the Consolidated Financial Statements, 
Page 118. None of the notes are encumbered by rating triggers:  
•  $391 million aggregate principal amount of 6.92% senior debentures due 2028. 
•  $28 million aggregate principal amount of 6.9% senior debentures due 2028. 
•  $374 million aggregate principal amount of 6.125% senior debentures due 2034. 
The company’s senior debt is rated investment grade by independent rating firms. On July 19, 2010, 
Standard & Poor’s lowered counterparty credit rating for our senior debt from BBB+ to BBB. Three other 
rating agencies made no changes to our debt ratings in 2010. Our debt ratings from the other rating 
agencies are: a from A.M. Best, BBB+ from Fitch Ratings and A3 from Moody’s Investors Service.  
Short-Term Debt 
At December 31, 2010, we had two lines of credit with commercial banks amounting to $225 million, 
with $49 million borrowed. There was no change in the amount of the $49 million short-term debt during 
2010 or 2009. Access to these lines of credit requires compliance with various covenants, including 
maintaining a minimum consolidated net worth and not exceeding a 20 percent debt-to-capital ratio. As of 
December 31, 2010, we were well within compliance with all of the covenants under the credit agreements 
and believe we will remain in compliance.  
Our $75 million unsecured line of credit with PNC Bank, N.A. was established more than five years ago and 
was renewed effective August 30, 2010, for a one-year term to expire on August 28, 2011. CFC Investment 
Company also is a borrower under this line of credit. PNC Bank is a subsidiary of The PNC Financial Services 
Group Inc. (NYSE:PNC). 
The second line of credit is an unsecured $150 million revolving line of credit administered by 
The Huntington National Bank. It was established in 2007 and will mature in 2012. CFC Investment 
Company also is a borrower under this line of credit. At year-end 2010, there was $49 million outstanding on 
this line of credit. The Huntington National Bank, a subsidiary of Huntington Bancshares Inc. 
(NASDAQ:HBAN), is the lead participant with a $75 million share. U.S. Bancorp (NYSE:USB), Bank of America 
Corporation (NYSE:BAC) and Northern Trust Corporation (NASDAQ:NTRS) also participate, each providing 
$25 million of capacity. 
This line of credit includes a swing line sub-facility for same-day borrowing in the amount of $35 million. 
The credit agreement provides alternative interest charges based on the type of borrowing and our 
debt rating. The interest rate charged for an advancement is adjusted LIBOR plus the applicable margin. 
Based on our debt ratings at year-end 2010, interest for Eurodollar rate advances is adjusted LIBOR plus 
33 basis points, and for floating rate advances is adjusted LIBOR. Utilization and commitment fees 
based on Cincinnati Financial Corporation’s year-end 2010 debt rating are 5 basis points and 8 basis 
points, respectively.  
Capital Resources 
Capital resources represent our overall financial strength to support writing and growing our insurance 
businesses. At December 31, 2010, we had total shareholders’ equity of $5.032 billion, an increase of 
$272 million, or 6 percent, from the prior year. Our total debt was $839 million, unchanged from a year ago. 
We seek to maintain a solid financial position and provide capital flexibility by keeping our ratio of debt to 
total capital moderate. We target a ratio below 20 percent. At year-end 2010, the ratio was 14.3 percent 
compared with 15.0 percent at year-end 2009. The decrease in the debt-to-total-capital ratio was due 
entirely to the increase in shareholders’ equity at year-end 2010.  
At the discretion of the board of directors, the company can return cash directly to shareholders:  
•  Dividends to shareholders –The ability of the company to continue paying cash dividends is subject to 

factors the board of directors may deem relevant. While the board and management believe there is 
merit to sustaining the company’s record of dividend increases, our first priority is the company’s 
financial strength. Over the past 10 years, the company has paid an average of 46.9 percent of net 
income as dividends. Through 2010, the board had increased our cash dividend for 50 consecutive 
years. The board decision in August 2010 to increase the dividend demonstrated confidence in the 
company’s strong capital, liquidity, financial flexibility and initiatives to improve earnings performance.  

Cincinnati Financial Corporation – 2010 10-K – Page 80 

•  Common stock repurchase – Generally, our board believes that share repurchases can help fulfill our 

commitment to enhancing shareholder value. Consequently, the board has authorized the repurchase of 
outstanding shares, giving management discretion to purchase shares at reasonable prices in light of 
circumstances at the time of purchase, pursuant to U.S. Securities and Exchange Commission (SEC) 
regulations. 

Consistent with our approach since mid-2008, we chose to preserve capital and repurchased a minimal 
amount of shares. Recent repurchases have been intended to partially offset the issuance of shares through 
equity compensation plans, primarily due to vesting of service-based restricted stock units of equity awards 
granted in the past. During the first half of 2008, we repurchased 3.8 million shares. In the past, repurchases 
have occurred when we believed that stock prices on the open market were favorable for such repurchases. 
Our corporate Code of Conduct restricts repurchases during certain time periods. The details of the 
repurchase authorizations and activity are described in Item 5, Market for the Registrant’s Common Equity, 
Related Stockholder Matters and Issuer Purchases of Equity Securities, Page 31.  
OBLIGATIONS 
We pay obligations to customers, suppliers and associates in the normal course of our business operations. 
Some are contractual obligations that define the amount, circumstances and/or timing of payments. We 
have other commitments for business expenditures; however, the amount, circumstances and/or timing of 
our other commitments are not dictated by contractual arrangements.  
Contractual Obligations 
As of December 31, 2010, we estimate our future contractual obligations as follows:  

(In millions)
Payment due by period
Gross property casualty loss and loss expense payments
Gross life policyholder obligations
Interest on long-term debt

Our two most significant contractual obligations are discussed in conjunction with related insurance reserves 
in Gross Property Casualty Loss and Loss Expense Payments and Gross Life Insurance Policyholder 
Obligations beginning on Pages 82 and 89, respectively. Other future contractual obligations include: 
• 

Interest on long- and short-term debt – We expect total interest expense to be approximately $52 million 
in 2011. We discuss outstanding debt in Additional Sources of Liquidity, Page 79. 

•  Property casualty profit-sharing commissions – Profit-sharing, or contingent, commissions are paid to 
agencies using a formula that takes into account agency profitability and other factors. We estimate 
2011 contingent commission payments of approximately $77 million. We discuss commission expense 
trends in Commercial Lines and Personal Lines Insurance Results of Operations, Page 54 and 
Page 64, respectively. 

•  Computer hardware and software – We expect to spend $45 million over the next three years for current 

material commitments for computer hardware and software, including maintenance contracts on 
hardware and other known obligations. We discuss below the non-contractual expenses we anticipate for 
computer hardware and software in 2011. 

Other Commitments  
As of December 31, 2010, we believe our most significant other commitments are:  
•  Qualified pension plan – In 2011, we made a voluntary cash contribution of $35 million to our qualified 
pension plan. We currently estimate a $13 million net pension expense and a $8 million expense for 
company 401(k) contributions. Going forward, we anticipate a lower cash pension contribution.  

•  Commissions – We expect commission payments to generally track with written premiums.  
•  Other operating expenses – Many of our operating expenses are not contractual obligations but reflect 
the ongoing expenses of our business. In addition to contractual obligations for hardware and software 
discussed above, we anticipate capitalizing approximately $8 million in spending for key technology 
initiatives in 2011. Capitalized development costs related to key technology initiatives totaled $7 million 
in 2010, $28 million in 2009 and $38 million in 2008. These activities are conducted at our discretion, 
and we have no material contractual obligations for activities planned as part of these projects.  

Cincinnati Financial Corporation – 2010 10-K – Page 81 

 
Liquidity and Capital Resources Outlook 
A long-term perspective governs our liquidity and capital resources decisions, with the goal of benefiting 
our policyholders, agents, shareholders and associates over time. While our insurance results for 2010 
and 2009 did not meet our combined ratio objective of being consistently below 100 percent, our 
improved capital position since year-end 2008 provided adequate cushion. We have taken the necessary 
steps to protect our capital and are confident in our strategies to return our insurance operations to growth 
and profitability. 
Our consistent cash flows and prudent cash balances continue to create strong liquidity. As of 
December 31, 2010, we had $385 million in cash and cash equivalents. That strong liquidity and our 
consistent cash flows gives us the flexibility to meet current obligations and commitments while building 
value by prudently investing where we see potential for both current income and long-term return.  
In any year, we consider the most likely source of pressure on liquidity would be an unusually high level of 
catastrophe loss payments within a short period of time. There could also be additional obligations for our 
insurance operations due to increasing severity or frequency of non-catastrophe claims. To address the risk 
of unusual insurance loss obligations including catastrophe events, we maintain property casualty 
reinsurance contracts with highly rated reinsurers, as discussed under 2011 Reinsurance Programs, 
Page 90. We also monitor the financial condition of our reinsurers because an insolvency could place in 
jeopardy a portion of our $572 million in outstanding reinsurance recoverables as of December 31, 2010. 
Continued economic weakness also has the potential to affect our liquidity and capital resources in a number 
of different ways, including: delinquent payments from agencies, defaults on interest payments by fixed-
maturity holdings in our portfolio, dividend reductions by holdings in our equity portfolio or declines in the 
market value of holdings in our portfolio. 
Further, parent company liquidity could be constrained by State of Ohio regulatory requirements that restrict 
the dividends insurance subsidiaries can pay. During 2011, total dividends that our insurance subsidiary can 
pay to our parent company without regulatory approval are approximately $378 million. 
Off-Balance-Sheet Arrangements 
We do not use any special-purpose financing vehicles or have any undisclosed off-balance-sheet 
arrangements (as that term is defined in applicable SEC rules) that are reasonably likely to have a current or 
future material effect on the company’s financial condition, results of operation, liquidity, capital 
expenditures or capital resources. Similarly, the company holds no fair-value contracts for which a lack of 
marketplace quotations would necessitate the use of fair-value techniques. 
Property Casualty Loss and Loss Expense Obligations and Reserves 
Gross Property Casualty Loss and Loss Expense Payments 
Our estimate of future gross property casualty loss and loss expense payments of $4.137 billion is lower than 
loss and loss expense reserves of $4.200 billion as of year-end 2010. The $63 million difference is due to 
life and health loss reserves, as discussed in Item 8, Note 5 of the Consolidated Financial Statements, 
Page 117. 
While we believe that historical performance of property casualty and life loss payment patterns is a 
reasonable source for projecting future claim payments, there is inherent uncertainty in this estimate of 
contractual obligations. We believe that we could meet our obligations under a significant and unexpected 
change in the timing of these payments because of the liquidity of our invested assets, strong financial 
position and access to lines of credit. 
Our estimates of gross property casualty loss and loss expense payments do not include 
reinsurance receivables or ceded losses. As discussed in 2011 Reinsurance Programs, Page 90, we 
purchase reinsurance to mitigate our property casualty risk exposure. Ceded property casualty reinsurance 
unpaid receivables of $326 million at year-end 2010 are an offset to our gross property casualty loss and 
loss expense obligations. Our reinsurance program mitigates the liquidity risk of a single large loss or an 
unexpected rise in claim severity or frequency due to a catastrophic event. Reinsurance does not relieve 
us of our obligation to pay covered claims. The financial strength of our reinsurers is important because 
our ability to recover losses under our reinsurance agreements depends on the financial viability of 
the reinsurers. 
We direct our associates and agencies to settle claims and pay losses as quickly as is practical and we made 
$1.865 billion of net claim payments during 2010. At year-end 2010, net property casualty reserves reflected 
$2.076 billion in unpaid amounts on reported claims (case reserves), $877 million in loss expense reserves 
and $858 million in estimates of claims that were incurred but had not yet been reported (IBNR). The specific 
amounts and timing of obligations related to case reserves and associated loss expenses are not set 
contractually. The amounts and timing of obligations for IBNR claims and related loss expenses are unknown. 
We discuss our methods of establishing loss and loss expense reserves and our belief that reserves are 

Cincinnati Financial Corporation – 2010 10-K – Page 82 

adequate in Critical Accounting Estimates, Property Casualty Insurance Loss and Loss Expense Reserves, 
Page 82. 
The historical pattern of using premium receipts for the payment of loss and loss expenses has enabled us to 
extend slightly the maturities of our investment portfolio beyond the estimated settlement date of the loss 
reserves. The effective duration of our consolidated fixed-maturity portfolio was 5.0 years at year-end 2010. 
By contrast, the duration of our loss and loss expense reserves was approximately three and one-half years. 
We believe this difference in duration does not affect our ability to meet current obligations because cash 
flow from operations is sufficient to meet these obligations. In addition, investment holdings could be sold, if 
necessary, to meet higher than anticipated loss and loss expenses. 
Range of Reasonable Reserves  
The company established a reasonably likely range for net loss and loss expense reserves of $3.571 billion 
to $3.952 billion at year-end 2010, with the company carrying net reserves of $3.811 billion. The likely range 
was $3.459 billion to $3.774 billion at year-end 2009, with the company carrying net reserves of 
$3.661 billion. Our loss and loss expense reserves are not discounted for the time-value of money, but we 
have reduced the reserves by an estimate of the amount of salvage and subrogation payments we expect to 
recover. We provide a reconciliation of the property casualty reserves with the loss and loss expense reserve 
as shown on the balance sheet in Item 8, Note 5 of the Consolidated Financial Statements, Page 117. 
The low point of each year’s range corresponds to approximately one standard error below each year’s mean 
reserve estimate, while the high point corresponds to approximately one standard error above each year’s 
mean reserve estimate. We discussed management’s reasons for basing reasonably likely reserve ranges on 
standard errors in Critical Accounting Estimates, Reserve Estimate Variability, Page 43.  
The ranges reflect our assessment of the most likely unpaid loss and loss expenses at year-end 2010 
and 2009. However, actual unpaid loss and loss expenses could nonetheless fall outside of the 
indicated ranges. 
Management’s best estimate of total loss and loss expense reserves as of year-end 2010 was consistent 
with the corresponding actuarial best estimate. Management’s best estimate of total loss and loss expense 
reserves as of year-end 2009 also was consistent with the corresponding actuarial best estimate.  
Development of Reserves for Loss and Loss Expenses 
We reconcile the beginning and ending balances of our reserves for loss and loss expenses at 
December 31, 2010, 2009 and 2008, in Item 8, Note 5 of the Consolidated Financial Statements, Page 117. 
The reconciliation of our year-end 2009 reserve balance to net incurred losses one year later recognizes 
approximately $304 million of favorable reserve development.  
The table on the following page shows the development of estimated reserves for loss and loss expenses for 
the past 10 years. 
•  Section A shows our total property casualty loss and loss expense reserves recorded at the balance 

sheet date for each of the indicated calendar years on a gross and net basis. Those reserves represent 
the estimated amount of unpaid loss and loss expenses for claims arising in the indicated calendar year 
and all prior accident years at the balance sheet date, including losses that were incurred but not yet 
reported to the company. 

•  Section B shows the cumulative net amount paid with respect to the previously recorded reserve as of 

the end of each succeeding year. For example, as of December 31, 2010, we had paid $1.797 billion of 
loss and loss expenses in calendar years 2001 through 2010 for losses that occurred in accident years 
2000 and prior. An estimated $237 million of losses remained unpaid as of year-end 2010 
(net re-estimated reserves of $2.034 billion from Section C less cumulative net paid loss and loss 
expenses of $1.797 billion).  

•  Section C shows the re-estimated amount of the previously reported reserves based on experience as of 
the end of each succeeding year. The estimate is increased or decreased as we learn more about the 
development of the related claims.  

•  Section D, cumulative net reserve development, represents the aggregate change in the estimates for all 
years subsequent to the year the reserves were initially established. For example, reserves established 
at December 31, 2000, had developed favorably by $148 million over 10 years, net of reinsurance, 
which was reflected in income over the 10 years. The table shows favorable reserve development as a 
negative number. Favorable reserve development on prior accident years, which represents a negative 
expense, is favorable to income. The “One year later” line in the table shows the effects on income 
before income taxes in 2010, 2009 and 2008 of changes in estimates of the reserves for loss and loss 
expenses for all accident years. The effect was favorable to pretax income for those three years by 
$304 million, $188 million, and $323 million, respectively. Our annual review has led us to add to 
income in each of the past 22 years due to favorable development of reserves on prior accident years.

In evaluating the development of our estimated reserves for loss and loss expenses for the past 10 years, 
note that each amount includes the effects of all changes in amounts for prior periods. For example, 
payments or reserve adjustments related to losses settled in 2010 but incurred in 2004 are included in the 
cumulative deficiency or redundancy amount for 2004 and each subsequent year. In addition, this table 
presents calendar year data, not accident or policy year development data, which readers may be more 
accustomed to analyzing. Conditions and trends that affected development of reserves in the past may not 
necessarily occur in the future. Accordingly, it may not be appropriate to extrapolate future reserve 
development based on this data.  
Differences between the property casualty reserves reported in the accompanying consolidated balance 
sheets (prepared in accordance with GAAP) and those same reserves reported in the annual statements 
(filed with state insurance departments in accordance with statutory accounting practices – SAP), relate 
principally to the reporting of reinsurance recoverables, which are recognized as receivables for GAAP and as 
an offset to reserves for SAP.

Asbestos and Environmental Reserves  
We carried $134 million of net loss and loss expense reserves for asbestos and environmental claims as of 
year-end 2010, compared with $118 million for such claims as of year-end 2009. These amounts constitute 
3.5 percent and 3.2 percent of total loss and loss expense reserves as of these year-end dates. 
We believe our exposure to asbestos and environmental claims is limited, largely because our reinsurance 
retention was $500,000 or below prior to 1987. We also predominantly were a personal lines company in the 
1960s and 1970s when asbestos and pollution exclusions were not widely used. During the 1980s and early 

Cincinnati Financial Corporation – 2010 10-K – Page 84 

 
 
 
  
  
  
  
  
  
  
  
  
  
  
 
1990s, commercial lines grew as a percentage of our overall business and our exposure to asbestos and 
environmental claims grew accordingly. Over that period, we endorsed to or included in most policies an 
asbestos and environmental exclusion. 
Additionally, since 2002, we have revised policy terms where permitted by state regulation to limit our 
exposure to mold claims prospectively and further reduce our exposure to other environmental claims 
generally. Finally, we have not engaged in any mergers or acquisitions through which such a liability could 
have been assumed. We continue to monitor our claims for evidence of material exposure to other mass tort 
classes such as silicosis, but we have found no such credible evidence to date.  
Reserving data for asbestos and environmental claims has characteristics that limit the usefulness of the 
methods and models used to analyze loss and loss expense reserves for other claims. Specifically, asbestos 
and environmental loss and loss expenses for different accident years do not emerge independently of one 
another as loss development and Bornhuetter-Ferguson methods assume. In addition, asbestos and 
environmental loss and loss expense data available to date does not reflect a well-defined tail, greatly 
complicating the identification of an appropriate probabilistic trend family model.  
Due to these considerations, our actuarial staff elected to use a paid survival ratio method to estimate 
reserves for incurred but not yet reported asbestos and environmental claims. Although highly uncertain, 
reserve estimates obtained via this method have developed in a reasonably stable fashion since 2004. Since 
our exposure to such claims is limited, we believe the paid survival ratio method is sufficient. Reserves for 
asbestos and environmental claims increased in 2010 as a result of changes in the identification of asbestos 
and environmental losses and is not related to new or additional asbestos and environmental exposures.

Overall favorable development for commercial lines reserves of $269 million in 2010 illustrated the potential 
for revisions inherent in estimating reserves, especially for long-tail lines such as commercial casualty and 
workers’ compensation. Favorable reserve development of $186 million for the commercial casualty line 
accounted for approximately 70 percent of the segment total in 2010, while favorable reserve development 
of $39 million for the workers’ compensation line accounted for approximately 15 percent of the segment 
total in 2010. Drivers of significant reserve development are discussed below.  
•  Moderation in commercial casualty trend selections – We saw moderating loss cost trends continue in 
several commercial casualty coverages, most notably for umbrella coverage. A number of factors seem 
to have played a role, including a slow economic recovery, favorable court decisions, policy form 
restrictions, and claims department initiatives. Accordingly, it is not entirely clear whether these 
moderating loss cost trends will persist, and our actuaries have responded cautiously to these changes, 
electing to recognize improvements in trends used for estimating reserves in a progressive, incremental 
fashion.  

•  Commercial casualty loss emergence – As in 2009, commercial multiple peril liability coverages 

contributed to favorable reserve development because both paid loss and reported loss emergence 
deviated favorably from projections. Actual paid losses in calendar year 2010 fell short of the amount 
projected at year-end 2009 by more than $20 million. Reported losses for accident years 2007 through 
2009 also developed more favorably than expected, while reported loss development related to other 
accident years aligned more closely with expectations.  

•  Commercial auto loss emergence – Similar to commercial casualty, commercial auto liability contributed 
to favorable development because both paid and reported loss emergence during calendar year 2010 
was substantially less than expected. As of December 31, 2009 we expected reported loss emergence in 
the next 12 calendar months to be approximately $26 million; actual emergence was $17 million. Paid 
loss emergence was approximately 15 percent lower than expected at the prior year-end.  

Cincinnati Financial Corporation – 2010 10-K – Page 86 

 
•  Workers’ compensation trends and initiatives – Favorable calendar year development was $39 million. 

Accident year 2009 contributed $54 million in favorable development while accident years 2003 and 
prior developed adversely by $11 million. Higher than anticipated trend continues to plague the older 
accident years causing us to raise our paid loss trend estimate for the second year in a row. However, 
projections of ultimate loss for accident years 2004-2008 held steady. The improvement in accident year 
2009 is likely an early manifestation of several claims initiatives begun in the first part of 2010, as 
discussed in Commercial Lines Insurance Results of Operations, Commercial Lines of Business Analysis, 
Page 58. 

 An examination of factors contributing to the remaining $9 million of commercial lines favorable reserve 
development, not accounted for by the commercial casualty, commercial auto and workers’ compensation 
lines, did not turn up any abnormal or unexpected variations. As noted in Critical Accounting Estimates, Key 
Assumptions - Loss Reserving, Page 43, our models predict that actual loss and loss expense emergence will 
differ from projections, and we do not attempt to monitor or identify such normal variations.  
Personal Lines Insurance Segment Reserves 
For the business lines in the personal lines insurance segment, the following table shows the components 
of gross reserves among case, IBNR and loss expense reserves. Total gross reserves for the segment in total 
were fairly stable, up approximately 1 percent from year-end 2009.

Favorable development for personal lines segment reserves illustrates the potential for revisions inherent in 
estimating reserves. Several factors discussed in Commercial Lines Insurance Segment Reserves, Page 85, 
that contributed to commercial lines segment reserve development in 2010 also contributed to personal 
lines favorable reserve development, most notably the factors related to umbrella coverage in the other 
personal line of business. 
In consideration of the data’s credibility, we analyze commercial and personal umbrella liability reserves 
together and then allocate the derived total reserve estimate to the commercial and personal coverages. 
Consequently, all of the umbrella factors that contributed to commercial lines reserve development also 
contributed to personal lines reserve development through the other personal line, of which personal 
umbrella coverages are a part.

Excess and Surplus Lines Insurance Segment Reserves 
For the excess and surplus lines insurance segment, the following table shows the components of gross 
reserves among case, IBNR and loss expense reserves. Total gross reserves were up from year-end 2009 
primarily due to the increase in premiums and exposures for this segment, as we discussed in Excess and 
Surplus Lines Insurance Results of Operations, Page 70. Favorable development during 2010 of $1 million 
for excess and surplus lines insurance segment reserves illustrates the potential for revisions inherent in 
estimating reserves. Factors affecting the modest favorable reserve development included the lack of a 
sufficiently long experience period on which to base reserve estimates.

Life Insurance Policyholder Obligations and Reserves  
Gross Life Insurance Policyholder Obligations 
Our estimates of life, annuity and disability policyholder obligations reflect future estimated cash payments to 
be made to policyholders for future policy benefits, policyholders’ account balances and separate account 
liabilities. These estimates include death and disability income claims, policy surrenders, policy maturities, 
annuity payments, minimum guarantees on separate account products, commissions and premium taxes 
offset by expected future deposits and premiums on in-force contracts.  
Our estimates of gross life, annuity and disability obligations do not reflect net recoveries from reinsurance 
agreements. Ceded life reinsurance receivables were $228 million at year-end 2010. As discussed in 
2011 Reinsurance Programs, Page 90, we purchase reinsurance to mitigate our life insurance risk exposure. 
At year-end 2010, ceded death benefits represented approximately 47.2 percent of our total policy face 
amounts in force.  
These estimated cash outflows are undiscounted with respect to interest. As a result, the sum of the cash 
outflows for all years of $3.848 billion (total of life insurance obligations) exceeds the liabilities recorded in 
life policy reserves and separate accounts for future policy benefits and claims of $2.692 billion (total of life 
insurance policy reserves and separate account policy reserves). Separate account policy reserves make up 
all but $3 million of separate accounts liabilities. 
We have made significant assumptions to determine the estimated undiscounted cash flows of these policies 
and contracts that include mortality, morbidity, future lapse rates and interest crediting rates. Due to the 
significance of the assumptions used, the amounts presented could materially differ from actual results. 
Life Insurance Reserves  
Gross life policy reserves were $2.034 billion at year-end 2010, compared with $1.783 billion at year-end 
2009. The increase was primarily due to reserves for deferred annuities. We establish reserves for traditional 
life insurance policies based on expected expenses, mortality, morbidity, withdrawal rates and investment 
yields, including a provision for uncertainty. Once these assumptions are established, they generally are 
maintained throughout the lives of the contracts. We use both our own experience and industry experience 
adjusted for historical trends in arriving at our assumptions for expected mortality, morbidity and withdrawal 
rates. We use our own experience and historical trends for setting our assumptions for expected expenses. 
We base our assumptions for expected investment income on our own experience adjusted for current 
economic conditions. 
We establish reserves for our universal life, deferred annuity and investment contracts equal to the 
cumulative account balances, which include premium deposits plus credited interest less charges and 
withdrawals. Some of our universal life insurance policies contain no-lapse guarantee provisions. For these 
policies, we establish a reserve in addition to the account balance based on expected no-lapse guarantee 
benefits and expected policy assessments. 
We regularly review our life insurance business to ensure that any deferred acquisition cost associated with 
the business is recoverable and that our actuarial liabilities (life insurance segment reserves) make sufficient 
provision for future benefits and related expenses.

2011 REINSURANCE PROGRAMS 
A single large loss or an unexpected rise in claims severity or frequency due to a catastrophic event 
could present us with a liquidity risk. In an effort to control such losses, we avoid marketing property casualty 
insurance in specific geographic areas and monitor our exposure in certain coastal regions. An example of 
this would be our recent depopulation of homeowner policies in the southeastern coastal region. This area 
was identified as a major contributor to our catastrophe probable maximum loss estimates and has 
subsequently been greatly reduced. We also continually review aggregate exposures to huge disasters and 
purchase reinsurance protection to cover these exposures. We use the Risk Management Solutions (RMS) 
and Applied Insurance Research (AIR) models to evaluate exposures to a once-in-a-100 year and a once-in-a-
250 year event to help determine appropriate reinsurance coverage programs. In conjunction with these 
activities, we also continue to evaluate information provided by our reinsurance broker. These various 
sources explore and analyze credible scientific evidence, including the impact of global climate change, 
which may affect our exposure under insurance policies. 
To help determine appropriate reinsurance coverage for hurricane, earthquake, and tornado/hail exposures, 
we use the RMS and AIR models to estimate the probable maximum loss from a single event occurring in a 
one‐year period. The models are proprietary in nature, and the vendors that provide them periodically update 
the models, sometimes resulting in significant changes to their estimate of probable maximum loss. As of the 
end of 2010, both models indicated a hurricane event represents our largest amount of exposure to losses. 
The table below summarizes estimated probabilities and the corresponding probable maximum loss from a 
single event occurring in a one‐year period for that exposure, and indicates the effect of such losses on 
consolidated shareholders’ equity as of December 31, 2010. Net losses are net of reinsurance and income 
taxes. The modeled losses according to RMS in the table are based on their RiskLink version 
10.0 catastrophe model and utilize a near‐term storm catalog methodology. The near-term storm catalog 
theory is a more conservative approach and places a higher weighting on the increased hurricane activity of 
the past several years, thus producing higher probable maximum loss projections than a longer term view. 
The modeled losses according to AIR in the table are based on their AIR Clasic/2 version 12 catastrophe 
model and utilize a long-term methodology. The AIR storm catalog includes decades of documented weather 
events used in simulations for probably maximum loss projections.

Reinsurance mitigates the risk of highly uncertain exposures and limits the maximum net loss that can arise 
from large risks or risks concentrated in areas of exposure. Management’s decisions about the appropriate 
level of risk retention are affected by various factors, including changes in our underwriting practices, 
capacity to retain risks and reinsurance market conditions. Reinsurance does not relieve us of our obligation 
to pay covered claims. The financial strength of our reinsurers is important because our ability to recover for 
losses covered under any reinsurance agreement depends on the financial viability of the reinsurer. 
Currently participating on our standard market property and casualty per-risk and per-occurrence programs 
are Hannover Reinsurance Company, Munich Reinsurance America, Partner Reinsurance Company of the 
U.S. and Swiss Reinsurance America Corporation, all of which have A.M. Best insurer financial strength 
ratings of A (Excellent) or A+ (Superior). Our property catastrophe program is subscribed through a broker by 
reinsurers from the United States, Bermuda, London and the European markets.  
Primary components of the 2011 property and casualty reinsurance program include:  
•  Property per risk treaty – The primary purpose of the property treaty is to provide capacity up to 
$25 million, adequate for the majority of the risks we write. It also includes protection for extra-
contractual liability coverage losses. We retain the first $6 million of each loss. Losses between 
$6 million and $25 million are reinsured at 100 percent. The ceded premium is estimated at $32 million 
for 2011, compared with $36 million in 2010 and $35 million in 2009. The lower ceded premium for 
2011 compared with 2010 is largely due to raising our loss retention of each loss from $5 million to $6 
million. 

•  Casualty per occurrence treaty – The casualty treaty provides capacity up to $25 million. Similar to the 
property treaty, it provides sufficient capacity to cover the vast majority of casualty accounts we insure 
and also includes protection for extra-contractual liability coverage losses. We retain the first $6 million 
of each loss. Losses between $6 million and $25 million are reinsured at 100 percent. The ceded

premium is estimated at $37 million in 2011, similar to the $37 million paid in 2010 and $38 million 
in 2009. 

•  Casualty excess treaties – We purchase a casualty reinsurance treaty that provides an additional 

$25 million in protection for certain casualty losses. This treaty, along with the casualty per occurrence 
treaty, provides a total of $50 million of protection for workers’ compensation, extra-contractual liability 
coverage and clash coverage losses, which would apply when a single occurrence involves multiple 
policyholders of The Cincinnati Insurance Companies or multiple coverages for one insured. The ceded 
premium is estimated at approximately $2 million in 2011, similar to the premium we paid in 
2010 and 2009.  
We purchase a second casualty excess treaty, which provides an additional $20 million in casualty loss 
coverage. This treaty also provides catastrophic coverage for workers’ compensation and extra-
contractual liability coverage losses. The ceded premium is estimated at approximately $1 million for 
2011, similar to the premium we paid in 2010 and 2009. 

•  Property catastrophe treaty – To protect against catastrophic events such as wind and hail, hurricanes or 
earthquakes, we purchase property catastrophe reinsurance with a limit up to $500 million. For the 
2011 treaty, ceded premiums are estimated at $49 million, similar to the $49 million in 2010 and 
$50 million in 2009. We retain the first $45 million of any loss and varying shares of losses up to 
$500 million:  
o  38.5 percent of losses between $45 million and $70 million 
o  17.6 percent of losses between $70 million and $105 million 
o  5.0 percent of losses between $105 million and $200 million  
o  11.3 percent of losses between $200 million and $300 million  
o  6.5 percent of losses between $300 million and $400 million  
o  5.0 percent of losses between $400 million and $500 million  
After reinsurance, our maximum exposure to a catastrophic event that caused $500 million in covered 
losses would be $88 million compared with $104 million in 2010. The largest catastrophe loss in our 
history was Hurricane Ike in September 2008, which was estimated to be $142 million before 
reinsurance at December 31, 2010. The treaty contains one reinstatement provision. 

Individual risks with insured values in excess of $25 million, as identified in the policy, are handled through a 
different reinsurance mechanism. We typically reinsure property coverage for individual risks with insured 
values between $25 million and $65 million under an automatic facultative agreement. For risks with 
property values exceeding $65 million, we negotiate the purchase of facultative coverage on an individual 
certificate basis. For casualty coverage on individual risks with limits exceeding $25 million, facultative 
reinsurance coverage is placed on an individual certificate basis. For risks with property or casualty limits 
which are between $25 million and $27 million, we sometimes forego facultative reinsurance and retain an 
additional $2 million of loss exposure. 
Terrorism coverage at various levels has been secured in most of our reinsurance agreements. The broadest 
coverage for this peril is found in the property and casualty working treaties, the property per risk treaty and 
the casualty per occurrence treaty, which provide coverage for commercial and personal risks. Our property 
catastrophe treaty provides terrorism coverage for personal risks, and coverage for commercial risks with 
total insured values of $10 million or less. For insured values between $10 million and $25 million, there 
also may be coverage in the property working treaty.  
A form of reinsurance is also provided through The Terrorism Risk Insurance Act of 2002 (TRIA). TRIA was 
originally signed into law on November 26, 2002, and extended on December 22, 2005, in a revised form, 
and extended again on December 26, 2007. TRIA provides a temporary federal backstop for losses related to 
the writing of the terrorism peril in property casualty insurance policies. TRIA now is scheduled to expire 
December 31, 2014. Under regulations promulgated under this statute, insurers are required to offer 
terrorism coverage for certain lines of property casualty insurance, including property, commercial multi-peril, 
fire, ocean marine, inland marine, liability, aircraft and workers’ compensation. In the event of a terrorism 
event defined by TRIA, the federal government would reimburse terrorism claim payments subject to the 
insurer’s deductible. The deductible is calculated as a percentage of subject written premiums for the 
preceding calendar year. Our deductible in 2010 was $369 million (20 percent of 2009 subject premiums), 
and we estimate it is $366 million (20 percent of 2010 subject premiums) in 2011.  
Reinsurance protection for the company’s surety business is covered under separate treaties with many of 
the same reinsurers that write the property casualty working treaties.  

Cincinnati Financial Corporation – 2010 10-K – Page 91 

The Cincinnati Specialty Underwriters Insurance Company, which began issuing insurance policies in 2008, 
has separate property and casualty reinsurance treaties for 2011 through The Cincinnati Insurance 
Company. Primary components of the treaties include: 
•  Property per risk treaty – The property treaty provides limits up to $5 million, which is adequate capacity 
for the risk profile we insure. It also includes protection for extra-contractual liability coverage losses. The 
Cincinnati Specialty Underwriters Insurance Company retains the first $1 million of any policy loss. 
Losses between $1 million and $5 million are reinsured at 100 percent by The Cincinnati 
Insurance Company. 

•  Casualty treaties – The casualty treaty is written on an excess of loss basis and provide limits up to 

$6 million, which is adequate capacity for the risk profile we insure. A second treaty layer of $5 million 
excess of $6 million is written to provide coverage for extra contractual obligations or clash exposures. 
The maximum retention for any one casualty loss is $1 million by The Cincinnati Specialty Underwriters 
Insurance Company. Losses between $1 million and $11 million are reinsured at 100 percent by The 
Cincinnati Insurance Company. 

•  Basket retention – The Cincinnati Specialty Underwriters Insurance Company has purchased this 

coverage to limit our retention to $1 million in the event that the same occurrence results in both a 
property and a casualty loss.  

•  Property catastrophe treaty – As a subsidiary of The Cincinnati Insurance Company, The Cincinnati 

Specialty Underwriters Insurance Company has been added as a named insured under our corporate 
property catastrophe treaty. All terms and conditions of this treaty apply to policies underwritten by 
The Cincinnati Specialty Underwriters Insurance Company.  

For property risks with limits exceeding $5 million or casualty risks with limits exceeding $6 million, 
underwriters place facultative reinsurance coverage on an individual certificate basis. 
Cincinnati Life, our life insurance subsidiary, purchases reinsurance under separate treaties with many of the 
same reinsurers that write the property casualty working treaties. In 2005, we modified our reinsurance 
protection for our term life insurance business due to changes in the marketplace that affected the cost and 
availability of reinsurance for term life insurance. We are retaining no more than a $500,000 exposure, 
ceding the balance using excess over retention mortality coverage, and retaining the policy reserve. Retaining 
the policy reserve has no direct impact on GAAP results. However, because of the conservative nature of 
statutory reserving principles, retaining the policy reserve unduly depresses our statutory earnings and 
requires a large commitment of our capital. We also have catastrophe reinsurance coverage on our life 
insurance operations that reimburses us for covered net losses in excess of $9 million. Our recovery is 
capped at $75 million for losses involving our associates. For term life insurance business written prior to 
2005, we retain 10 percent to 25 percent of each term policy, not to exceed $500,000, ceding the balance 
of mortality risk and policy reserve. 
SAFE HARBOR STATEMENT 
This is our “Safe Harbor” statement under the Private Securities Litigation Reform Act of 1995. Our business is 
subject to certain risks and uncertainties that may cause actual results to differ materially from those suggested by 
the forward-looking statements in this report. Some of those risks and uncertainties are discussed in Item 1A, Risk 
Factors, Page 24. Although we often review or update our forward-looking statements when events warrant, we 
caution our readers that we undertake no obligation to do so. 
Factors that could cause or contribute to such differences include, but are not limited to:  
•  Unusually high levels of catastrophe losses due to risk concentrations, changes in weather patterns, 

environmental events, terrorism incidents or other causes  
Increased frequency and/or severity of claims 
Inadequate estimates or assumptions used for critical accounting estimates  

• 
• 
•  Recession or other economic conditions resulting in lower demand for insurance products or increased 

payment delinquencies 

•  Delays in adoption and implementation of underwriting and pricing methods that could increase our pricing 

• 

accuracy, underwriting profit and competitiveness 
Inability to defer policy acquisition costs for any business segment if pricing and loss trends would lead 
management to conclude that segment could not achieve sustainable profitability 

•  Declines in overall stock market values negatively affecting the company’s equity portfolio and book value 
• 

Events, such as the credit crisis, followed by prolonged periods of economic instability or recession, that lead to: 
o  Significant or prolonged decline in the value of a particular security or group of securities and impairment 

of the asset(s) 

o  Significant decline in investment income due to reduced or eliminated dividend payouts from a particular 

security or group of securities 

o  Significant rise in losses from surety and director and officer policies written for financial institutions

Prolonged low interest rate environment or other factors that limit the company’s ability to generate growth in 
investment income or interest rate fluctuations that result in declining values of fixed-maturity investments, 
including declines in accounts in which we hold bank-owned life insurance contract assets 
Increased competition that could result in a significant reduction in the company’s premium volume 
Changing consumer insurance-buying habits and consolidation of independent insurance agencies that could 
alter our competitive advantages  
Inability to obtain adequate reinsurance on acceptable terms, amount of reinsurance purchased, financial 
strength of reinsurers and the potential for non-payment or delay in payment by reinsurers 
Events or conditions that could weaken or harm the company’s relationships with its independent agencies and 
hamper opportunities to add new agencies, resulting in limitations on the company’s opportunities for growth, 
such as:  
o  Downgrades of the company’s financial strength ratings  
o  Concerns that doing business with the company is too difficult  
o  Perceptions that the company’s level of service, particularly claims service, is no longer a distinguishing 

characteristic in the marketplace 

o  Delays or inadequacies in the development, implementation, performance and benefits of technology 

projects and enhancements  

Actions of insurance departments, state attorneys general or other regulatory agencies, including a change to a 
federal system of regulation from a state-based system, that: 
o  Restrict our ability to exit or reduce writings of unprofitable coverages or lines of business 
o  Place the insurance industry under greater regulatory scrutiny or result in new statutes, rules 

and regulations  

o  Add assessments for guaranty funds, other insurance-related assessments or mandatory reinsurance 

arrangements; or that impair our ability to recover such assessments through future surcharges or other 
rate changes 
Increase our provision for federal income taxes due to changes in tax law 
Increase our other expenses 
Limit our ability to set fair, adequate and reasonable rates  

o 
o 
o 
o  Place us at a disadvantage in the marketplace  
o  Restrict our ability to execute our business model, including the way we compensate agents 
Adverse outcomes from litigation or administrative proceedings 
Events or actions, including unauthorized intentional circumvention of controls, that reduce the company’s 
future ability to maintain effective internal control over financial reporting under the Sarbanes-Oxley Act 
of 2002  

•  Unforeseen departure of certain executive officers or other key employees due to retirement, health or 

other causes that could interrupt progress toward important strategic goals or diminish the effectiveness of 
certain longstanding relationships with insurance agents and others 
Events, such as an epidemic, natural catastrophe or terrorism, that could hamper our ability to assemble our 
workforce at our headquarters location  

• 

•  Difficulties with technology or data security breaches that could negatively affect our ability to conduct 

business and our relationships with agents, policyholders and others 

Further, the company’s insurance businesses are subject to the effects of changing social, economic and 
regulatory environments. Public and regulatory initiatives have included efforts to adversely influence and restrict 
premium rates, restrict the ability to cancel policies, impose underwriting standards and expand overall regulation. 
The company also is subject to public and regulatory initiatives that can affect the market value for its common 
stock, such as measures affecting corporate financial reporting and governance. The ultimate changes and 
eventual effects, if any, of these initiatives are uncertain. 
Item 7A.  Quantitative and Qualitative Disclosures About 

Market Risk 

INTRODUCTION 
Market risk is the potential for a decrease in securities value resulting from broad yet uncontrollable forces 
such as: inflation, economic growth, interest rates, world political conditions or other widespread 
unpredictable events. It is comprised of many individual risks that, when combined, create a macroeconomic 
impact. The company accepts and manages risks in the investment portfolio as part of the means of 
achieving portfolio objectives. Some of the risks are:  
•  Political – the potential for a decrease in value due to the real or perceived impact of governmental 

policies or conditions 

Cincinnati Financial Corporation – 2010 10-K – Page 93 

•  Regulatory – the potential for a decrease in value due to the impact of legislative proposals or changes in 

laws or regulations  

•  Economic – the potential for a decrease in value due to changes in general economic factors (recession, 

inflation, deflation, etc.)  

•  Revaluation – the potential for a decrease in value due to a change in relative value (change in market 

multiple) of the market brought on by general economic factors  

• 

Interest-rate – the potential for a decrease in value of a security or portfolio due to its sensitivity to 
changes (increases or decreases) in the general level of interest rates  

•  Company-specific risk – the potential for a particular issuer to experience a decline in value due to the 

impact of sector or market risk on the holding or because of issues specific to the firm 

• 

Fraud – the potential for a negative impact on an issuer’s performance due to actual or alleged illegal or 
improper activity of individuals it employs 

•  Credit – the potential for deterioration in an issuer’s financial profile due to specific company issues, 

problems it faces in the course of its operations or industry-related issues 

•  Default – the possibility that an issuer will not make a required payment (interest payment or return of 
principal) on its debt. Generally this occurs after its financial profile has deteriorated (credit risk) and it 
no longer has the means to make its payments  

The investment committee of the board of directors monitors the investment risk management process 
primarily through its executive oversight of our investment activities. We take an active approach to 
managing market and other investment risks, including the accountabilities and controls over these 
activities. Actively managing these market risks is integral to our operations and could require us to change 
the character of future investments purchased or sold or require us to shift the existing asset portfolios to 
manage exposure to market risk within acceptable ranges.  
Sector risk is the potential for a negative impact on a particular industry due to its sensitivity to factors that 
make up market risk. Market risk affects general supply/demand factors for an industry and affects 
companies within that industry to varying degrees. 
Risks associated with the five asset classes described in Item 1, Investments Segment, Page 19, can be 
summarized as follows (H – high, A – average, L – low):

FIXED-MATURITY INVESTMENTS 
For investment-grade corporate bonds, the inverse relationship between interest rates and bond prices leads 
to falling bond values during periods of increasing interest rates. We address this risk by attempting to 
construct a generally laddered maturity schedule that allows us to reinvest cash flows at prevailing rates. 
Although the potential for a worsening financial condition, and ultimately default, does exist with investment-
grade corporate bonds, we address this risk by performing credit analysis and monitoring as well as 
maintaining a diverse portfolio of holdings. 
The primary risk related to high-yield corporate bonds is credit risk or the potential for a deteriorating 
financial structure. A weak financial profile can lead to rating downgrades from the credit rating agencies, 
which can put further downward pressure on bond prices. Interest rate risk, while significant, is less of a 
factor with high-yield corporate bonds, as valuation is related more directly to underlying operating 
performance than to general interest rates. This puts more emphasis on the financial results achieved by the 
issuer rather than on general economic trends or statistics within the marketplace. We address this concern 
by analyzing issuer- and industry-specific financial results and by closely monitoring holdings within this 
asset class. 
The primary risks related to tax-exempt bonds are interest rate risk and political risk associated with the 
specific economic environment within the political boundaries of the issuing municipal entity. We address 
these concerns by focusing on municipalities’ general-obligation debt and on essential-service bonds. 
Essential-service bonds derive a revenue stream from municipal services that are vital to the people living in 

Cincinnati Financial Corporation – 2010 10-K – Page 94 

 
the area (water service, sewer service, etc.). Another risk related to tax-exempt bonds is regulatory risk or the 
potential for legislative changes that would negate the benefit of owning tax-exempt bonds. We monitor 
regulatory activity for situations that may negatively affect current holdings and our ongoing strategy for 
investing in these securities.  
The final, less significant risk is our exposure to credit risk for a portion of the tax-exempt portfolio that has 
support from corporate entities. Examples are bonds insured by corporate bond insurers or bonds with 
interest payments made by a corporate entity through a municipal conduit/authority. Our decisions regarding 
these investments primarily consider the underlying municipal situation. The existence of third-party 
insurance is intended to reduce risk in the event of default. In circumstances in which the municipality is 
unable to meet its obligations, risk would be increased if the insuring entity were experiencing financial 
duress. Because of our diverse exposure and selection of higher-rated entities with strong financial profiles, 
we do not believe this is a material concern as we discuss in Item 1, Investments Segment, Page 19. 
Interest Rate Sensitivity Analysis  
Because of our strong surplus, long-term investment horizon and ability to hold most fixed-maturity 
investments to maturity, we believe the company is well positioned if interest rates were to rise. A higher rate 
environment would provide the opportunity to invest cash flow in higher-yielding securities, while reducing the 
likelihood of untimely redemptions of currently callable securities. While higher interest rates would be 
expected to increase the number of fixed-maturity holdings trading below 100 percent of book value, we 
believe lower fixed-maturity security values due solely to interest rate changes would not signal a decline in 
credit quality.  
Our dynamic financial planning model uses analytical tools to assess market risks. As part of this model, the 
effective duration of the fixed-maturity portfolio is continually monitored by our investment department to 
evaluate the theoretical impact of interest rate movements.  
The table below summarizes the effect of hypothetical changes in interest rates on the 
fixed-maturity portfolio:

The effective duration of the fixed maturity portfolio was 5.0 years at year-end 2010, compared with 
5.3 years at year-end 2009. A 100 basis point movement in interest rates would result in an approximately 
5.0 percent change in the fair value of the fixed maturity portfolio. Generally speaking, the higher a bond is 
rated, the more directly correlated movements in its fair value are to changes in the general level of interest 
rates, exclusive of call features. The fair values of average- to lower-rated corporate bonds are additionally 
influenced by the expansion or contraction of credit spreads. 
In the dynamic financial planning model, the selected interest rate change of 100 to 200 basis points 
represents our views of a shift in rates that is quite possible over a one-year period. The rates modeled 
should not be considered a prediction of future events as interest rates may be much more volatile in the 
future. The analysis is not intended to provide a precise forecast of the effect of changes in rates on our 
results or financial condition, nor does it take into account any actions that we might take to reduce exposure 
to such risks.  
EQUITY INVESTMENTS 
Common stocks are subject to a variety of risk factors encompassed under the umbrella of market risk. 
General economic swings influence the performance of the underlying industries and companies within those 
industries. As we saw in 2008, a downturn in the economy can have a negative effect on an equity portfolio. 
Industry- and company-specific risks also have the potential to substantially affect the value of our portfolio. 
We implemented new investment guidelines in 2008 to help address these risks by diversifying the portfolio 
and establishing parameters to help manage exposures.  
Our equity holdings represented $3.041 billion in fair value and accounted for approximately 60 percent of 
the unrealized appreciation of the entire portfolio at year-end 2010. See Item 1, Investments Segment, 
Page 19, for additional details on our holdings.  
The primary risks related to preferred stocks are similar to those related to investment grade corporate 
bonds. Rising interest rates adversely affect market values due to the normal inverse relationship between 
interest rates and bond prices. Credit risk exists due to the subordinate position of preferred stocks in the 
capital structure. We minimize this risk by primarily purchasing investment grade preferred stocks of issuers 
with a strong history of paying a common stock dividend.

SHORT-TERM INVESTMENTS 
Our short-term investments historically consisted primarily of commercial paper, demand notes or bonds 
purchased within one year of maturity. In 2009, we made short-term investments primarily with funds to be 
used to make upcoming cash payments, such as taxes. 
APPLICATION OF ASSET IMPAIRMENT POLICY 
As discussed in Item 7, Critical Accounting Estimates, Asset Impairment, Page 44, our fixed-maturity and 
equity investment portfolios are evaluated differently for other-than-temporary impairments. The company’s 
asset impairment committee monitors a number of significant factors for indications that the value of 
investments trading below the carrying amount may not be recoverable. The application of our impairment 
policy resulted in OTTI charges that reduced our income before income taxes by $36 million in 2010, $131 
million in 2009 and $510 million in 2008. Impairments are discussed in Item 7, Investment Results of 
Operations, Page 75. 
We expect the number of securities trading below 100 percent of book value to fluctuate as interest rates 
rise or fall and credit spreads expand or contract due to prevailing economic conditions. Further, book values 
for some securities have been revised due to impairment charges recognized in prior periods. At year-end 
2010, 316 of the 2,671 securities we owned were trading below 100 percent of book value compared with 
355 of the 2,505 securities we owned at year-end 2009 and 944 of the 2,233 securities we owned at 
year-end 2008.  
The 316 holdings trading below book value at year-end 2010 represented 10.6 percent of invested assets 
and $49 million in unrealized losses.  
•  312 of these holdings were trading between 90 percent and 100 percent of book value. The value 
of these securities fluctuates primarily because of changes in interest rates. The fair value of these 
312 securities was $1.124 billion at year-end 2010, and they accounted for $26 million in 
unrealized losses.  

•  4 of these holdings were trading between 70 percent and 90 percent of book value. The fair value of 
these holdings was $101 million, and they accounted for $23 million in unrealized losses. These 
securities, which are being closely monitored, have been affected by a combination of factors including 
wider credit spreads driven primarily by the distress in the mortgage market, slumping real estate 
valuations, the effects of a slowing economy and the effects of higher interest rates on longer duration 
instruments. The majority of these securities are in the financial-related sectors. 

•  No securities were trading below 70 percent of book value at year-end 2010.  
The following table summarizes the length of time securities in the investment portfolio have been in a 
continuous unrealized gain or loss position.

Financial Statements and Supplementary Data 

Item 8. 
RESPONSIBILITY FOR FINANCIAL STATEMENTS 
We have prepared the consolidated financial statements of Cincinnati Financial Corporation and our 
subsidiaries for the year ended December 31, 2010, in accordance with accounting principles generally 
accepted in the United States of America (GAAP). 
We are responsible for the integrity and objectivity of these financial statements. The amounts, presented on 
an accrual basis, reflect our best estimates and judgment. These statements are consistent in all material 
aspects with other financial information in the Annual Report on Form 10-K. Our accounting system and 
related internal controls are designed to assure that our books and records accurately reflect the company’s 
transactions in accordance with established policies and procedures as implemented by qualified personnel. 
Our board of directors has established an audit committee of independent outside directors. We believe 
these directors are free from any relationships that could interfere with their independent judgment as audit 
committee members. 
The audit committee meets periodically with management, our independent registered public accounting firm 
and our internal auditors to discuss how each is handling responsibilities. The audit committee reports its 
findings to the board of directors. The audit committee recommends to the board the annual appointment of 
the independent registered public accounting firm. The audit committee reviews with this firm the scope of 
the audit assignment and the adequacy of internal controls and procedures. 
Deloitte & Touche LLP, our independent registered public accounting firm, audited the consolidated financial 
statements of Cincinnati Financial Corporation and subsidiaries for the year ended December 31, 2010. Its 
report is on Page 100. Deloitte’s auditors met with our audit committee to discuss the results of their 
examination. They have the opportunity to discuss the adequacy of internal controls and the quality of 
financial reporting without management present.

MANAGEMENT’S ANNUAL REPORT ON INTERNAL CONTROL OVER FINANCIAL 
REPORTING 
The management of Cincinnati Financial Corporation and its subsidiaries is responsible for establishing and 
maintaining adequate internal controls, designed to provide reasonable assurance regarding the reliability of 
financial reporting and the preparation of financial statements for external purposes in accordance with 
accounting principles generally accepted in the United States of America (GAAP). The company’s internal 
control over financial reporting includes those policies and procedures that:  
•  Pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the 

transactions and dispositions of the assets of the company;  

•  Provide reasonable assurance that transactions are recorded as necessary to permit preparation of 

financial statements in accordance with GAAP and that receipts and expenditures of the company are 
being made only in accordance with authorizations of management and the directors of the company; 
and  

•  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. 
All internal control systems, no matter how well designed, have inherent limitations, including the possibility 
of human error and the circumvention of overriding controls. Accordingly, even effective internal control can 
provide only reasonable assurance with respect to financial statement preparation and presentation. Further, 
because of changes in conditions, the effectiveness of internal control may vary over time. 
The company’s management assessed the effectiveness of the company’s internal control over financial 
reporting as of December 31, 2010, as required by Section 404 of the Sarbanes Oxley Act of 2002. 
Management’s assessment was based on the criteria established in the Internal Control – Integrated 
Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission and was 
designed to provide reasonable assurance that the company maintained effective internal control over 
financial reporting as of December 31, 2010. The assessment led management to conclude that, as of 
December 31, 2010, the company’s internal control over financial reporting was effective based on those 
criteria. 
The company’s independent registered public accounting firm has issued an audit report on our internal 
control over financial reporting as of December 31, 2010. This report appears on Page 100.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM  
To the Shareholders and Board of Directors of Cincinnati Financial Corporation 
Fairfield, Ohio 
We have audited the accompanying consolidated balance sheets of Cincinnati Financial Corporation and 
subsidiaries (the company) as of December 31, 2010 and 2009, and the related consolidated statements of 
income, shareholders’ 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(c). We also have audited the company’s internal control over financial reporting as of December 31, 2010, 
based on criteria established in the Internal Control – Integrated Framework issued by the Committee of 
Sponsoring Organizations of the Treadway Commission. The company’s management is responsible for these 
financial statements and financial statement schedules, for maintaining effective internal control over financial 
reporting, and for its assessment of the effectiveness of internal control over financial reporting, included in 
Management’s Annual Report on Internal Control Over Financial Reporting. Our responsibility is to express an 
opinion on these financial statements and financial statement schedules and an opinion on the company’s 
internal control over financial reporting 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 and whether effective internal control 
over financial reporting was maintained in all material respects. Our audit of the financial statements included 
examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, 
assessing the accounting principles used and significant estimates made by management, and evaluating the 
overall financial statement presentation. Our audit of internal control over financial reporting 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. 
Our audits also included performing such other procedures as we considered necessary in the circumstances. 
We believe that our audits provide a reasonable basis for our opinions. 
A company’s internal control over financial reporting is a process designed by, or under the supervision of, 
the company’s principal executive and principal financial officers, or persons performing similar functions, and 
effected by the company’s board of directors, management, and other personnel 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 the inherent limitations of internal control over financial reporting, including the possibility of 
collusion or improper management override of controls, material misstatements due to error or fraud may not 
be prevented or detected on a timely basis. Also, projections of any evaluation of the effectiveness of the 
internal control over financial reporting to future periods are subject to the risk that the 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, the consolidated financial statements referred to above present fairly, in all material respects, 
the financial position of the company as of December 31, 2010 and 2009, and the results of their operations 
and their cash flows for each of the three years in the period ended December 31, 2010, in conformity with 
accounting principles generally accepted in the United States of America. Also, in our opinion, such financial 
statement schedules, when considered in relation to the basic consolidated financial statements taken as a 
whole, present fairly, in all material respects, the information set forth therein. Also, in our opinion, the company 
maintained, in all material respects, effective internal control over financial reporting as of December 31, 2010, 
based on the criteria established in Internal Control – Integrated Framework issued by the Committee of 
Sponsoring Organizations of the Treadway Commission. 
As discussed in Note 1 to the consolidated financial statements, the company changed its method of 
accounting for the recognition and presentation of other-than-temporary impairments in 2009.

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES 

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS 
1.   
Nature of Operations 
Cincinnati Financial Corporation operates through our insurance group and two complementary 
subsidiary companies.  
The Cincinnati Insurance Company leads our standard market property casualty insurance group that also 
includes two subsidiaries: The Cincinnati Casualty Company and The Cincinnati Indemnity Company. This 
group markets a broad range of standard market business, homeowner and auto policies. The group 
provides quality customer service to our select group of 1,245 independent insurance agencies with 
1,544 reporting locations across 39 states. Other subsidiaries of The Cincinnati Insurance Company include 
The Cincinnati Life Insurance Company, which markets life and disability income insurance and annuities, 
and The Cincinnati Specialty Underwriters Insurance Company, which began offering excess and surplus lines 
property and casualty insurance products in 2008.  
The two complementary subsidiaries are CSU Producer Resources Inc., which offers insurance brokerage 
services to our independent agencies so their clients can access our excess and surplus lines insurance 
products, and CFC Investment Company (CFC-I), which offers commercial leasing and financing services to 
our agents, their clients and other customers.  
Basis of Presentation 
Our consolidated financial statements include the accounts of the parent and its subsidiaries, each of which 
are wholly owned, and are presented in conformity with accounting principles generally accepted in the 
United States of America (GAAP). All significant intercompany balances and transactions have been 
eliminated in consolidation. 
The preparation of financial statements in conformity with GAAP requires us to make estimates and 
assumptions that affect amounts reported in the financial statements and accompanying notes. Our actual 
results could differ from those estimates.  
In the first quarter of 2010, we changed our presentation of earned premiums in our consolidated 
statements of income. We have summarized property casualty and life earned premiums to a single caption, 
“Earned premiums.” See Note 10, Reinsurance, Page 119, for further detail on property casualty and life 
earned premiums. 
In the second quarter of 2010, we changed our presentation of long-term debt in our consolidated balance 
sheets. We have summarized the long-term debt to a single caption, “Long-term debt.” See Note 8, Senior 
Debt, Page 118, for further detail on interest rates, year of issue and maturity of our long-term debt. 
In the fourth quarter of 2010, we revised our reportable segments to establish a separate reportable 
segment for excess and surplus lines. This segment includes results of The Cincinnati Specialty Underwriters 
Insurance Company and CSU Producer Resources. Historically, the excess and surplus lines results were 
reflected in Other. We began offering excess and surplus lines insurance products in 2008. Separating 
excess and surplus lines into a reportable segment allows readers to view this business in a manner similar 
to how it is managed internally when making operating decisions. Prior period data included in this annual 
report has been recasted to represent this new segment.  
In the fourth quarter of 2010, we changed our presentation of other income in our consolidated statements 
of income. We have allocated the portion that primarily represents premium installment fees into a separate 
single caption, “Fee revenues.” Also, the remaining amount from the historic single caption, “Other income,” 
is presented as “Other revenues.” 
Earnings per Share 
Net income per common share is based on the weighted average number of common shares outstanding 
during each of the respective years. We calculate net income per common share (diluted) assuming the 
exercise of stock-based awards. We have adjusted shares and earnings per share to reflect all stock splits 
and dividends prior to December 31, 2010. 
Stock-Based Compensation 
We grant qualified and non-qualified stock-based compensation under authorized plans. The stock options 
vest ratably over three years following the date of grant and are exercisable over 10-year periods. In 2010, 
the committee approved a mix of stock options and restricted stock units for stock-based awards. See 
Note 17, Stock-Based Associate Compensation Plans, Page 125, for further details.  

Cincinnati Financial Corporation – 2010 10-K – Page 105 

Employee Benefit Pension Plan  
We sponsor a defined benefit pension plan that was modified during 2008. We froze entry into the pension 
plan, and only participants 40 years of age or older could elect to remain in the plan. Our pension expense is 
based on certain actuarial assumptions and also is composed of several components that are determined 
using the projected unit credit actuarial cost method. Refer to Note 13, Employee Retirement Benefits, 
Page 121 for more information regarding our defined benefit pension plan.  
Property Casualty Insurance 
Property casualty written premiums are deferred and recorded as earned premiums on a pro rata basis over 
the terms of the policies. We record as unearned premiums the portion of written premiums that applies to 
unexpired policy terms. The expenses associated with issuing insurance policies – primarily commissions, 
premium taxes and underwriting costs – are deferred and amortized over the terms of the policies. We 
assess recoverability of deferred acquisition costs at the segment level, consistent with the ways we acquire, 
service and manage insurance and measure profitability. We analyze our acquisition cost assumptions 
periodically to reflect actual experience and we test for potential premium deficiencies.  
A premium deficiency is recorded when the sum of expected loss and loss adjustment expenses, expected 
policyholder dividends, unamortized acquisition costs and maintenance costs exceeds the total of unearned 
premiums and anticipated investment income. A premium deficiency is first recognized by charging any 
unamortized acquisition costs to expense to the extent required to eliminate the deficiency. If the premium 
deficiency is greater than unamortized acquisition costs, a liability is accrued for the excess deficiency. We 
did not record a premium deficiency for the three years ended 2010, 2009 and 2008. 
Certain property casualty policies are not booked before the effective date. An actuarial estimate is made to 
determine the amount of unbooked written premiums. The majority of the estimate is unearned and does not 
have a material impact on earned premium.  
We establish reserves to cover the expected cost of claims, or losses, and our expenses related to 
investigating, processing and resolving claims. Although determining the appropriate amount of reserves is 
inherently uncertain, we base our decisions on past experience and current facts. Reserves are based on 
claims reported prior to the end of the year and estimates of unreported claims. We take into account the 
fact that we may recover some of our costs through salvage and subrogation. We regularly review and update 
reserves using the most current information available. Any resulting adjustments are reflected in current year 
insurance losses and policyholder benefits. 
The consolidated property casualty companies actively write property casualty insurance through 
independent agencies in 39 states. Our 10 largest states generated 67.1 percent and 68.1 percent of total 
earned premiums in 2010 and 2009. Ohio, our largest state, accounted for 20.5 percent and 21.0 percent of 
total earned premiums in 2010 and 2009. Georgia, Illinois, Indiana, Michigan, North Carolina, Pennsylvania 
and Virginia each accounted for between 4 percent and 9 percent of total earned premiums in 2010. Our 
largest single agency relationship accounted for approximately 1.2 percent of the company's total earned 
premiums in 2010.  
Policyholder Dividends 
Certain workers’ compensation policies include the possibility of a policyholder earning a return of a portion 
of its premium in the form of a policyholder dividend. The dividend generally is calculated by determining 
the profitability of a policy year along with the associated premium. We reserve for all probable future 
policyholder dividend payments. We incur policyholder dividends as underwriting, acquisition and 
insurance expenses. 
Contingent Commission Accrual 
We base the contingent commission accrual estimate on property casualty underwriting results. 
Contingent commissions are paid to agencies using a formula that takes into account agency profitability, 
premium volume and other factors, such as prompt monthly payment of amounts due to the company. 
The contingent commission accrual of $77 million in 2010 contributed 2.6 percentage points to the property 
casualty combined ratio. Contingent commission accruals for 2009 and 2008 were $81 million and 
$75 million, respectively.  
Life and Health Insurance  
We offer several types of life insurance and disability income insurance, and we account for each according 
to the duration of the contract. Short-duration contracts are written to cover claims that arise during a short, 
fixed term of coverage. We generally have the right to change the amount of premium charged or cancel the 
coverage at the end of each contract term. Group life insurance is an example. We record premiums for 
short-duration contracts similarly to property casualty contracts.  
Long-duration contracts are written to provide coverage for an extended period of time. Traditional long-
duration contracts require policyholders to pay scheduled gross premiums, generally not less frequently than 
annually, over the term of the coverage. Premiums for these contracts are recognized as revenue when due. 

Cincinnati Financial Corporation – 2010 10-K – Page 106 

Whole life insurance and disability income insurance are examples. Some traditional long-duration contracts 
have premium payment periods shorter than the period over which coverage is provided. For these contracts, 
the excess of premium over the amount required to pay expenses and benefits is recognized over the term of 
the coverage rather than over the premium payment period. Ten-pay whole life insurance is an example.  
We establish a liability for traditional long-duration contracts as we receive premiums. The amount of this 
liability is the present value of future expenses and benefits less the present value of future net premiums. 
Net premium is the portion of gross premium required to provide for all expenses and benefits. We estimate 
future expenses and benefits and net premium using assumptions for expected expenses, mortality, 
morbidity, withdrawal rates and investment income. We include a provision for deviation, meaning we allow 
for some uncertainty in making our assumptions. We establish our assumptions when the contract is issued 
and we generally maintain those assumptions for the life of the contract. We use both our own experience 
and industry experience, adjusted for historical trends, in arriving at our assumptions for expected mortality, 
morbidity and withdrawal rates. We use our own experience and historical trends for setting our assumption 
for expected expenses. We base our assumption for expected investment income on our own experience, 
adjusted for current economic conditions.  
When we issue a traditional long-duration contract, we capitalize acquisition costs. Acquisition costs are 
costs that vary with, and are primarily related to, the production of new business. We then charge these 
deferred policy acquisition costs to expenses over the premium-paying period of the contract, and we use the 
same assumptions that we use when we establish the liability for the contract. We update our acquisition 
cost assumptions periodically to reflect actual experience, and we evaluate our deferred acquisition cost 
for recoverability. 
Universal life contracts are long-duration contracts for which contractual provisions are not fixed, unlike 
whole life insurance. Universal life contracts allow policyholders to vary the amount of premium, within limits, 
without our consent. However, we may vary the mortality and expense charges, within limits, and the interest 
crediting rate used to accumulate policy values. We do not record universal life premiums as revenue. 
Instead we recognize as revenue the mortality charges, administration charges and surrender charges when 
received. Some of our universal life contracts assess administration charges in the early years of the contract 
that are compensation for services we will provide in the later years of the contract. These administration 
charges are deferred and are recognized over the period when we provide those future services. 
For universal life long-duration contracts, we maintain a liability equal to the policyholder account value. 
There is no provision for adverse deviation. Some of our universal life policies contain no-lapse guarantee 
provisions. For these policies, we establish a reserve in addition to the account balance, based on expected 
no-lapse guarantee benefits and expected policy assessments. 
When we issue a universal life long-duration contract, we capitalize acquisition costs. We then charge these 
capitalized costs to expenses over the term of coverage of the contract. When we charge deferred policy 
acquisition costs to expenses, we use assumptions based on our best estimates of long-term experience. 
We review and modify these assumptions on a regular basis. 
Separate Accounts 
We issue life contracts with guaranteed minimum returns, referred to as bank-owned life insurance contracts 
(BOLIs). We legally segregate and record as separate accounts the assets and liabilities for some of our 
BOLIs, based on the specific contract provisions. We guarantee minimum investment returns, account values 
and death benefits for our separate account BOLIs. Our other BOLIs are general account products.  
We carry the assets of separate account BOLIs at fair value. The liabilities on separate account BOLIs 
primarily are the contract holders’ claims to the related assets and are carried at an amount equal to the 
contract holders’ account value. At December 31, 2010, the current fair value of the BOLI invested assets 
and cash exceeded the current fair value of the contract holders’ account value by approximately 
$15 million. If the BOLI projected fair value were to fall below the value we guaranteed, a liability would be 
established by a charge to the company’s earnings.  
Generally, investment income and realized investment gains and losses of the separate accounts accrue 
directly to the contract holder, and we do not include them in the Consolidated Statements of Income. 
Revenues and expenses related to separate accounts consist of contractual fees and mortality, surrender 
and expense risk charges. Also, each separate account BOLI includes a negotiated capital gain and loss 
sharing arrangement with the company. A percentage of each separate account’s realized capital gain and 
loss representing contract fees and assessments accrues to us and is transferred from the separate account 
to our general account and is recognized as revenue or expense.  
Reinsurance 
We reduce risk and uncertainty by buying property casualty and life reinsurance. Reinsurance contracts do 
not relieve us from our duty to policyholders, but rather help protect our financial strength to perform that 
duty. All of our reinsurance contracts transfer the economic risk of loss. 

Cincinnati Financial Corporation – 2010 10-K – Page 107 

We also serve in a limited way as a reinsurer for other insurance companies, reinsurers and involuntary state 
pools. We record our transactions for such assumed reinsurance based on reports provided to us by the 
ceding reinsurer.  
Both reinsurance assumed and ceded premiums are deferred and recorded as earned premiums on a pro 
rata basis over the terms of the contract. We estimate loss amounts recoverable from our reinsurers based 
on the reinsurance policy terms. Historically, our claims with reinsurers have been paid. We do not have an 
allowance for uncollectible reinsurance. 
Cash and Cash Equivalents 
Cash and cash equivalents are highly liquid instruments that include liquid debt instruments with original 
maturities of less than three months. These are carried at cost and approximate fair value.  
Investments 
Our portfolio investments are primarily in publicly traded fixed-maturity, equity and short-term investments. 
Fixed-maturity investments (taxable bonds, tax-exempt bonds and redeemable preferred stocks) and equity 
investments (common and non-redeemable preferred stocks) are classified as available for sale and 
recorded at fair value in the consolidated financial statements. The number of fixed-maturity securities 
trading below 100 percent of book value can be expected to fluctuate as interest rates rise or fall. Because 
of our strong surplus and long-term investment horizon, our general intent is to hold fixed-maturity 
investments until maturity, regardless of short-term fluctuations in fair values. 
On April 1, 2009, we adopted a subsection of Accounting Standards Codification (ASC) 320, Recognition and 
Presentation of Other-Than-Temporary Impairments (OTTI). Our invested asset impairment policy states that 
fixed maturities the company (1) intends to sell or (2) are more likely than not will be required to sell before 
recovery of their amortized cost basis are deemed to be other-than-temporarily impaired. The book value of 
any such securities is reduced to fair value as the new cost basis, and a realized loss is recorded in the 
period in which it is recognized. When these two criteria are not met, and the company believes that full 
collection of interest and/or principal is not likely, we determine the net present value of future cash flows by 
using the effective interest rate implicit in the security at the date of acquisition as the discount rate and 
compare that amount to the amortized cost and fair value of the security. The difference between the net 
present value of the expected future cash flows and amortized cost of the security is considered a credit loss 
and recognized as a realized loss in the period in which it occurred. The difference between the fair value and 
the net present value of the cash flows of the security, the non credit loss, is recognized in other 
comprehensive income as an unrealized loss. With the adoption of this subsection of ASC 320 in the second 
quarter of 2009, we recognized a cumulative effect adjustment of $106 million, net of tax, to reclassify the 
non-credit component of previously recognized impairments by increasing retained earnings and reducing 
accumulated other comprehensive income (AOCI).  
ASC 320 does not allow retrospective application of the new other-than-temporary impairment model. 
Our consolidated statements of income for the year ended December 31, 2010 and 2009, are not measured 
on the same basis as December 31, 2008 and, accordingly, these amounts are not comparable. 
When determining OTTI charges for our equity portfolio, our invested asset impairment policy considers 
qualitative and quantitative factors, including facts and circumstances specific to individual securities, asset 
classes, the financial condition of the issuer, changes in dividend payment, the length of time fair value had 
been less than book value, the severity of the decline in fair value below book value, the volatility of the 
security and our ability and intent to hold each position until its forecasted recovery. 
Included within our other invested assets are $40 million of life policy loans, $28 million of venture capital 
fund investments and $5 million of investments in real estate. Life policy loans are carried at the receivable 
value, which approximates fair value. We use the equity method of accounting for venture capital fund 
investments. The venture capital funds provide their financial statements to us and generally report 
investments on their balance sheets at fair value. Investment in real estate consists of one office building 
that is carried at cost less accumulated depreciation.  
We include the non credit portion of fixed maturities and all other unrealized gains and losses on 
investments, net of taxes, in shareholders’ equity as AOCI. Realized gains and losses on investments are 
recognized in net income based on the trade date accounting method.  
Investment income consists mainly of interest and dividends. We record interest on an accrual basis and 
record dividends at the ex-dividend date. We amortize premiums and discounts on fixed-maturity securities 
using the effective interest method over the expected life of the security.  
Fair Value Disclosures 
We account for our investment portfolio at fair value and apply fair value measurements as defined by 
ASC 820, Fair Value Measurements and Disclosures, to financial instruments. Fair value is applicable to 
ASC 320, Investments-Debt and Equity Securities, ASC 815, Derivatives and Hedging, and ASC 825, 
Financial Instruments. 

Cincinnati Financial Corporation – 2010 10-K – Page 108 

Fair Value Measurements defines fair value as the exit price or the amount that would be (1) received to sell 
an asset or (2) paid to transfer a liability in an orderly transaction between marketplace participants at the 
measurement date. When determining an exit price, we rely upon observable market data whenever 
possible. We primarily base fair value for investments in equity and fixed-maturity securities (including 
redeemable preferred stock and assets held in separate accounts) on quoted market prices or on prices from 
FT Interactive Data, an outside resource that supplies global securities pricing, dividend, corporate action and 
descriptive information to support fund pricing, securities operations, research and portfolio management. 
When a price is not available from these sources, as in the case of securities that are not publicly traded, we 
determine the fair value using various inputs including quotes from independent brokers. The fair value of 
investments not priced by FT Interactive Data is less than 1 percent of the fair value of our total 
investment portfolio. See Note 3, Fair Value Measurements, Page 114, for further details. 
For the purpose of ASC 825 disclosure, we estimate the fair value for liabilities of investment contracts and 
annuities. We also estimate the fair value for assets arising from policyholder loans on insurance contracts. 
These estimates are developed using discounted cash flow calculations across a wide range of economic 
interest rate scenarios with a provision for our own credit risk. We base fair value for long-term senior notes 
on the quoted market prices for such notes. We base fair value for notes payable on our year-end 
outstanding balance. 
Derivative Financial Instruments and Hedging Activities 
We account for derivative financial instruments as defined by ASC 815, Derivatives and Hedging. The 
hedging definitions included in ASC 815 guide our recognition of the changes in the fair value of derivative 
financial instruments as realized gains or losses in the consolidated statements of income or as a 
component of AOCI in shareholder’s equity in the period for which they occur. 
Securities Lending Program 
During the third quarter of 2008, we terminated our securities lending program.  
Lease/Finance 
Our leasing subsidiary provides auto and equipment direct financing (leases and loans) to commercial and 
individual clients. We generally transfer ownership of the property to the client as the terms of the leases 
expire. Our lease contracts contain bargain purchase options. We record income over the financing term 
using the effective interest method. Finance receivables are reviewed for impairment on a quarterly basis. 
Impairment of our finance receivables are considered insignificant to our consolidated financial condition, 
results of operations and cash flows. 
We capitalize and amortize lease or loan origination costs over the life of the financing using the effective 
interest method. These costs may include, but are not limited to: finder fees, broker fees, filing fees and the 
cost of credit reports. We account for these leases and loans as direct financing-type leases. 
Land, Building and Equipment 
We record land at cost, and record building and equipment at cost less accumulated depreciation. Certain 
equipment held under capital leases also is classified as property and equipment with the related lease 
obligations recorded as liabilities. Our depreciation is based on estimated useful lives (ranging from three 
years to 39½ years) using straight-line and accelerated methods. Depreciation expense was $40 million in 
2010, $48 million in 2009, and $35 million in 2008. We monitor land, building and equipment for potential 
impairments. Potential impairments may include a significant decrease in the fair values of the assets, 
considerable cost overruns on projects or a change in legal factors or business climate, or other factors that 
indicate that the carrying amount may not be recoverable. There were no recorded land, building and 
equipment impairments for 2010, 2009 or 2008. 
We capitalize and amortize costs for internally developed computer software during the application 
development stage. These costs generally consist of external consulting, payroll and payroll-related costs.  
Income Taxes 
We calculate deferred income tax liabilities and assets using tax rates in effect for the time when temporary 
differences in financial statement income and taxable income are expected to reverse. We recognize 
deferred income taxes for numerous temporary differences between our taxable income and financial 
statement income and other changes in shareholders’ equity. Such temporary differences relate primarily to 
unrealized gains and losses on investments and differences in the recognition of deferred acquisition costs 
and insurance reserves. We charge deferred income taxes associated with unrealized appreciation and 
depreciation (except the amounts related to the effect of income tax rate changes) to shareholders’ equity in 
AOCI. We charge deferred taxes associated with other differences to income. 
See Note 11, Income Taxes, Page 120, for further detail on our uncertain tax positions. Although no Internal 
Revenue Service (IRS) penalties currently are accrued, if incurred, they would be recognized as a component 
of income tax expense. Accrued IRS interest expense is recognized as other operating expense in the 
consolidated statements of income.

Subsequent Events 
There were no subsequent events requiring adjustment to the financial statements or disclosure. 
Pending Accounting Standards 
• 

In January 2010, the FASB issued ASU 2010-06, Fair Value Measurements and Disclosures. ASU 2010-
06 applies to all entities that are required to make disclosures about recurring or nonrecurring fair value 
measurements. ASU 2010-06 requires separate disclosures of the activity in the Level 3 category 
related to any purchases, sales, issuances and settlements on a gross basis. The effective date of the 
disclosures regarding Level 3 category purchases, sales, issuances and settlements is for interim and 
annual periods beginning after December 15, 2010. The portion of ASU 2010-06 that we have not 
yet adopted will not have a material impact on our company’s financial position, cash flows or results 
of operations as it focuses on additional disclosures. 
In April 2010, the FASB issued ASU 2010-15, How Investments Held through Separate Accounts Affect 
an Insurer’s Consolidation Analysis of Those Investments. ASU 2010-15 applies to all insurance entities 
that have separate accounts that meet the definition and requirements set in the Accounting Standards 
Codification Manual. ASU 2010-15 clarifies that an insurance entity should not consider any separate 
account interests held for the benefit of contract holders in an investment to be the insurer’s interests. 
The insurance entity should not combine those interests with its general account interest in the same 
investment when assessing the investment for consolidation. The insurance entity may combine those 
interests when the separate account interests are held for the benefit of a related-party policyholder as 
defined in the Variable Interest Subsections of Consolidation topic in the Codification Manual. The 
effective date of the amendments in this update is for interim and annual periods beginning after 
December 15, 2010, with early adoption permitted. The amendments in this update do not modify the 
disclosures currently required by GAAP and are not expected to have a material impact on our company’s 
financial position, cash flows or results of operations. 

In October 2010, the FASB issued ASU 2010-26, Accounting for Costs Associated with Acquiring or 
Renewing Insurance Contracts. ASU 2010-26 modifies the definitions of the type of costs incurred by 
insurance entities that can be capitalized in the successful acquisition of new and renewal insurance 
contracts. ASU 2010-26 requires incremental direct costs of successful contract acquisition as well as 
certain costs related to underwriting, policy issuance and processing, medical and inspection and sales 
force contract selling for successful contract acquisition to be capitalized. These incremental direct costs 
and other costs are those that are essential to the contract transaction and would not have been 
incurred had the contract transaction not occurred. The effective date of ASU 2010-26 is for interim and 
annual reporting periods beginning after December 15, 2011. The ASU has not yet been adopted, and 
we are currently evaluating the impact this ASU will have on our company’s financial position, cash flows 
or results of operations. 

Adopted Accounting Standards 
• 

In February 2010, the FASB issued ASU 2010-08, Technical Corrections to Various Topics. ASU 2010-08 
does not change any of the fundamentals of GAAP, but it does explain certain clarifications made to the 
guidance on embedded derivatives and hedging. We have adopted ASU 2010-08, effective for the first 
reporting period after issuance and for fiscal years beginning after December 15, 2009. It did not have a 
material impact on our company’s financial position, cash flows or results of operations.  
In February 2010, the FASB issued ASU 2010-09, Subsequent Events. ASU 2010-09 removes the 
requirement for U.S. Securities and Exchange Commission (SEC) filers to disclose the date through which 
subsequent events have been evaluated in both issued and revised financial statements. We have 
adopted ASU 2010-09, effective for the first reporting period after issuance. It did not have a material 
impact on our company’s financial position, cash flows or results of operations.  
In July 2010, the FASB issued ASU 2010-20, Disclosures about the Credit Quality of Financing 
Receivables and the Allowance for Credit Losses. ASU 2010-20 will improve transparency in financial 
reporting for companies that hold financing receivables, which include loans, lease receivables and other 
long-term receivables. The additional disclosures required by ASU 2010-20 are effective for interim and 
annual reporting periods ending on or after December 15, 2010. The ASU did not have a material impact 
on our company’s financial position, cash flows or results of operations.

The unrealized investment gains at December 31, 2010, were largely due to a net gain position in our fixed 
income portfolio of $495 million and a net gain position in our common stock portfolio of $729 million. 
The two primary contributors to the net gain position were The Procter & Gamble Company (NYSE:PG) and 
Exxon Mobil Corporation (NYSE:XOM) common stocks, which had a combined net gain position of 
$237 million. At December 31, 2010, we had $69 million fair value of hybrid securities included in fixed 
maturities that follow ASC 815-15-25, Accounting for Certain Hybrid Financial Instruments. The hybrid 
securities are carried at fair value, and the changes in fair value are included in realized investment gains 
and losses.

For the year ended December 31, 2010 and 2009, there were no credit losses on fixed-maturity securities 
for which a portion of OTTI has been recognized in other comprehensive income. 
During 2010, we impaired 15 securities. At December 31, 2010, 17 fixed-maturity investments with a total 
unrealized loss of $4 million had been in an unrealized loss position for 12 months or more. Of that total, 
no fixed maturity investments were trading below 70 percent of book value. Three equity investments with a 
total unrealized loss of $1 million had been in an unrealized loss position for 12 months or more as of 
December 31, 2010. Of that total, no equity investments were trading below 70 percent of book value.  
During 2009, we impaired 50 securities. At December 31, 2009, 121 fixed-maturity investments with a total 
unrealized loss of $25 million had been in an unrealized loss position for 12 months or more. Of that total, 
eight fixed maturity investments were trading below 70 percent of book value with a total unrealized loss of 
$2 million. Ten equity investments with a total unrealized loss of $26 million had been in an unrealized loss 
position for 12 months or more as of December 31, 2009. Of that total, no equity investments were trading 
below 70 percent of book value.  
During 2008, we impaired 126 securities. At December 31, 2008, 142 fixed-maturity investments with a 
total unrealized loss of $78 million had been in an unrealized loss position for 12 months or more. Of that 
total, no fixed-maturity investments were trading below 70 percent of book value. Six equity investments with 
a total unrealized loss of $41 million had been in an unrealized loss position for 12 months or more as of 
December 31, 2008, with two trading below 70 percent of book value.  
When determining OTTI charges for our fixed-maturity portfolio, management places significant emphasis on 
whether issuers of debt are current on contractual payments and whether future contractual amounts are 
likely to be paid. As required by ASC 320 effective April 1, 2009, our invested asset impairment policy for 
fixed-maturity securities states that OTTI is considered to have occurred (1) if we intend to sell the impaired 
fixed maturity security; (2) if it is more likely than not we will be required to sell the fixed maturity security 
before recovery of its amortized cost basis; or (3) the present value of the expected cash flows is not 
sufficient to recover the entire amortized cost basis. If we intend to sell or it is more likely than not we will be 
required to sell, the book value of any such securities is reduced to fair value as the new cost basis, and a 
realized loss is recorded in the period in which it is recognized. When we believe that full collection of interest 
and/or principal is not likely, we determine the net present value of future cash flows by using the effective 
interest rate implicit in the security at the date of acquisition as the discount rate and compare that amount 
to the amortized cost and fair value of the security. The difference between the net present value of the 
expected future cash flows and amortized cost of the security is considered a credit loss and recognized as a 
realized loss in the period in which it occurred. The difference between the fair value and the net present 
value of the cash flows of the security, the non-credit loss, is recognized in other comprehensive income as 
an unrealized loss.  
With the adoption of ASC 320 in the second quarter of 2009, we recognized a cumulative effect adjustment 
of $106 million, net of tax, to reclassify the non-credit component of previously recognized impairments by 
increasing retained earnings and reducing AOCI. ASC 320 does not allow retrospective application of the new 
OTTI model. Our consolidated statements of income for the year ended December 31, 2010 and 2009, are 
not measured on the same basis as December 31, 2008, and, accordingly, these amounts are not 
comparable.  
When determining OTTI charges for our equity portfolio, our invested asset impairment policy considers 
qualitative and quantitative factors, including facts and circumstances specific to individual securities, asset 
classes, the financial condition of the issuer, changes in dividend payment, the length of time fair value had 
been less than book value, the severity of the decline in fair value below book value, the volatility of the 
security and our ability and intent to hold each position until its forecasted recovery. 
For each of our equity securities in an unrealized loss position at December 31, 2010, we applied the 
objective quantitative and qualitative criteria of our invested asset impairment policy for OTTI. Our long-term 
equity investment philosophy, emphasizing companies with strong indications of paying and growing 
dividends, combined with our strong surplus, liquidity and cash flow, provides us the ability to hold these 
investments through what we believe to be slightly longer recovery periods occasioned by the recession and 
historic levels of market volatility. Based on the individual qualitative and quantitative factors, as discussed 
above, we evaluate and determine an expected recovery period for each security. A change in the condition

cost within the expected recovery period, the security is impaired.  
3.   
FAIR VALUE MEASUREMENTS 
Fair Value Hierarchy 
In accordance with fair value measurements and disclosures, we categorized our financial instruments, 
based on the priority of the observable and market-based data for valuation technique, into a three-level fair 
value hierarchy. The fair value hierarchy gives the highest priority to quoted prices with readily available 
independent data in active markets for identical assets or liabilities (Level 1) and the lowest priority to 
unobservable market inputs (Level 3). When various inputs for measurement fall within different levels of the 
fair value hierarchy, the lowest observable input that has a significant impact on fair value measurement is 
used. Our valuation techniques have not changed since December 31, 2009, and ultimately management 
determines fair value. 
Financial instruments are categorized based upon the following characteristics or inputs to the 
valuation techniques: 
• 

Level 1 – Financial assets and liabilities for which inputs are observable and are obtained from reliable 
quoted prices for identical assets or liabilities in active markets. This is the most reliable fair value 
measurement and includes, for example, active exchange-traded equity securities. 
Level 2 – Financial assets and liabilities for which values are based on quoted prices in markets that are 
not active or for which values are based on similar assets and liabilities that are actively traded. This also 
includes pricing models for which the inputs are corroborated by market data.  
Level 3 – Financial assets and liabilities for which values are based on prices or valuation techniques 
that require inputs that are both unobservable and significant to the overall fair value measurement. 
Level 3 inputs include the following: 
o  Quotes from brokers or other external sources that are not considered binding; 
o  Quotes from brokers or other external sources where it cannot be determined that market 

• 

• 

participants would in fact transact for the asset or liability at the quoted price; 

o  Quotes from brokers or other external sources where the inputs are not deemed observable. 
We conduct a thorough review of fair value hierarchy classifications on a quarterly basis. Reclassification of 
certain financial instruments may occur when input observability changes. As noted below in the Level 3 
disclosure table, reclassifications are reported as transfers in or out of the Level 3 category as of the 
beginning of the quarter in which the reclassification occurred. 

Cincinnati Financial Corporation – 2010 10-K – Page 114 

The following tables illustrate the fair value hierarchy for those assets measured at fair value on a recurring 
basis for the years ended December 31, 2010 and 2009. We do not have any material liabilities carried at 
fair value. There were also no significant transfers between Level 1 and Level 2.

For the year ended December 31, 2010, one Level 3 corporate fixed-maturity security was purchased for 
$5 million and two corporate fixed-maturity securities were sold for approximately $1 million. There were also 
two corporate fixed-maturity securities that matured during the period for approximately $7 million. As a 
result of these purchases, sales, issuances and settlements, corporate fixed-maturity securities decreased 
$3 million.

The expenses associated with issuing insurance policies – primarily commissions, premium taxes and 
underwriting costs – are deferred and amortized over the terms of the policies. We update our acquisition 
cost assumptions periodically to reflect actual experience, and we evaluate our deferred acquisition costs for 
recoverability. The table below shows the deferred policy acquisition costs and asset reconciliation, including 
the amortized deferred policy acquisition costs.

There were no premium deficiencies recorded in the reported consolidated statements of income, as the sum 
of the anticipated loss and loss adjustment expenses, policyholder dividends, maintenance expenses and 
underwriting expenses did not exceed the related unearned premiums and anticipated investment income.

We use actuarial methods, models and judgment to estimate, as of a financial statement date, the property 
casualty loss and loss expense reserves required to pay for and settle all outstanding insured claims, 
including incurred but not reported (IBNR) claims, as of that date. The actuarial estimate is subject to review 
and adjustment by an inter-departmental committee that includes actuarial management and is familiar with 
relevant company and industry business, claims and underwriting trends, as well as general economic and 
legal trends, that could affect future loss and loss expense payments. The amount we will actually have to 
pay for claims can be highly uncertain. This uncertainty, together with the size of our reserves, makes the loss 
and loss expense reserves our most significant estimate. 
Because of changes in estimates of insured events in prior years, we decreased the provision for prior 
accident years’ loss and loss expenses by $304 million, $188 million and $323 million in calendar years 
2010, 2009 and 2008. These decreases are partly due to the effects of settling reported (case) and 
unreported (IBNR) reserves established in prior years for amounts less than expected. The reserve 
for loss and loss expenses in the consolidated balance sheets also includes $63 million 
at December 31, 2010, and $46 million for both 2009 and 2008, for certain life and health loss reserves.  
6.   
We establish the reserves for traditional life insurance policies based on expected expenses, mortality, 
morbidity, withdrawal rates and investment yields, including a provision for uncertainty. Once these 
assumptions are established, they generally are maintained throughout the lives of the contracts. 
We use both our own experience and industry experience, adjusted for historical trends, in arriving at our 
assumptions for expected mortality, morbidity and withdrawal rates as well as for expected expenses. 
We base our assumptions for expected investment income on our own experience adjusted for current 
economic conditions. 
We establish reserves for the company’s universal life, deferred annuity and investment contracts equal to 
the cumulative account balances, which include premium deposits plus credited interest less charges and 
withdrawals. Some of our universal life policies contain no-lapse guarantee provisions. For these policies, 
we establish a reserve in addition to the account balance, based on expected no-lapse guarantee benefits 
and expected policy assessments.

Reserves for deferred annuities and other investment contracts were $930 million and $736 million at 
December 31, 2010, and December 31, 2009, respectively. Fair value for these deferred annuities and 
investment contracts was $933 million and $737 million at December 31, 2010, and December 31, 2009, 
respectively. Fair values of liabilities associated with certain investment contracts are calculated based upon 
internally developed models because active, observable markets do not exist for those items. To determine 
the fair value, we make the following significant assumptions: (1) the discount rates used to calculate the 
present value of expected payments are the risk-free spot rates plus an A3 rated bond spread for financial 
issuers as of December 31, 2010, to account for non-performance risk; (2) the rate of interest credited to 

Cincinnati Financial Corporation – 2010 10-K – Page 117 

 
 
NOTES PAYABLE 

policyholders is the portfolio net earned interest rate less a spread for expenses and profit; and (3) additional 
lapses occur when the credited interest rate is exceeded by an assumed competitor credited rate, which is a 
function of the risk-free rate of the economic scenario being modeled. The fair value of life policy loans 
outstanding principal and interest approximated $46 million, compared with book value of $40 million 
reported in the consolidated balance sheets at December 31, 2010. The fair value of life policy loans 
outstanding principal and interest approximated $44 million, compared with book value of $40 million 
reported in the consolidated balance sheets as of December 31, 2009. 
7.   
At December 31, 2010 and 2009, we had two lines of credit with commercial banks with an aggregate 
borrowing capacity of $225 million. Our note payable balance, which approximates fair value, was 
$49 million at year-end 2010 and at year-end 2009. The $75 million line of credit expires August of 2011. 
The $150 million line of credit with a $49 million balance expires July of 2012. We had no compensating 
balance requirements on short-term debt for either 2010 or 2009. The interest rate charged on our 
borrowings was a fixed 2.58 percent during 2010.

SHAREHOLDERS’ EQUITY AND DIVIDEND RESTRICTIONS 

The fair value of our senior debt approximated $783 million at year-end 2010 compared with $740 million at 
year-end 2009. Fair value for 2010 and 2009 was determined under ASC 820 based on market pricing of 
these or similar debt instruments that are actively trading. Fair value can vary with macroeconomic concerns. 
Regardless of the fluctuations in fair value, the outstanding principal amount of our long-term debt remained 
unchanged from year-end 2009. None of the notes are encumbered by rating triggers. 
9.   
Our insurance subsidiary declared dividends to the parent company of $220 million in 2010, $50 million in 
2009 and $160 million in 2008. State regulatory requirements restrict the dividends insurance subsidiaries 
can pay. Generally, the most our insurance subsidiary can pay without prior regulatory approval is the greater 
of 10 percent of policyholder surplus or 100 percent of statutory net income for the prior calendar year. 
Dividends exceeding these limitations may be paid only with approval of the insurance department of the 
domiciliary state. During 2011, the total that our lead subsidiary may pay in dividends is approximately 
$378 million. 
As of December 31, 2010, 6 million shares of common stock were available for future equity award grants. 
Declared cash dividends per share were $1.59, $1.57 and $1.56 for the years ended 
December 31, 2010, 2009 and 2008, respectively.

The provision for federal income taxes is based upon filing a consolidated income tax return for the company 
and its subsidiaries. As of December 31, 2010, we had no operating or capital loss carry forwards.

Unrecognized Tax Benefits 
As a result of positions taken in our federal tax returns filed with the IRS, we believe it is more likely than not 
that tax positions for which we previously carried a liability for unrecognized tax benefits will be sustained 
upon examination by the IRS.

In December 2010, we reached agreement with the IRS settling all issues related to the 2007 and 2008 tax 
years. As a result of this IRS agreement, there is no liability for unrecognized tax benefits as of 
December 31, 2010. Tax year 2009 has not been audited by the IRS and remains open for examination. 
In addition to our IRS filings, we file income tax returns with immaterial amounts in various state jurisdictions.

Basic earnings per share are computed based on the weighted average number of shares outstanding. 
Diluted earnings per share are computed based on the weighted average number of common and dilutive 
potential common shares outstanding. We have adjusted shares and earnings per share to reflect all stock 
splits and dividends prior to December 31, 2010.

EMPLOYEE RETIREMENT BENEFITS 

The current sources of dilution of our common shares are certain equity-based awards as discussed in 
Note 17 Stock-Based Associate Compensation Plans, Page 125. The above table shows the number of 
anti-dilutive stock-based awards at year-end 2010, 2009 and 2008. We did not include these stock-based 
awards in the computation of net income per common share (diluted) because their exercise would have 
anti-dilutive effects. 
13.  
We sponsor a defined benefit pension plan and a defined contribution plan (401(k) savings plan). During 
2008, we changed the form of retirement benefit we offer some associates to a company match on 
contributions to the 401(k) plan from the defined benefit pension plan. In addition, we froze entry into the 
pension plan for new associates as of June 30, 2008. Only participants 40 years of age or older as of 
August 31, 2008, could elect to continue to participate. For participants who left the pension plan, benefit 
accruals were frozen as of August 31, 2008. We transferred $60 million of the pension plan’s accumulated 
benefit obligation during 2008 to an intermediary spin-off plan to facilitate the partial curtailment and 
settlement for these participants. For participants remaining in the pension plan, we continue to contribute to 
fund future benefit obligations. Benefits for the defined benefit pension plan are based on years of credited 
service and compensation level. Contributions are based on the prescribed method defined in the Pension 
Protection Act. Our pension expense is based on certain actuarial assumptions and also is composed of 
several components that are determined using the projected unit credit actuarial cost method. 
Matching contributions to our sponsored 401(k) plan, which we began making during 2008, totaled $8 
million, $7 million and $3 million during the years 2010, 2009 and 2008. Associates who are not accruing 
benefits under the pension plan are eligible to receive the company match of up to 6 percent of cash 
compensation. We also pay all operating expenses for the 401(k) plan. Participants vest in the company 
match for the 401(k) plan and Top Hat Savings Plan after three years of eligible service. 
We also maintain a supplemental executive retirement plan (SERP) with liabilities of approximately $6 million 
at year-end 2010 and $5 million at year-end 2009, which are included in the obligation and expense 
amounts. The company also makes available to a select group of associates the Cincinnati Financial 
Corporation Top Hat Savings Plan, a non-qualified deferred compensation plan.  
For SERP participants who chose to leave the defined benefit pension plan, SERP benefit accruals were 
frozen as of December 31, 2008. During 2009, the frozen accrued SERP benefit for those participants, 
collectively amounting to approximately $1 million, transferred to the Top Hat Savings Plan. Beginning in 
2009, for these associates, the company began matching deferrals to the Top Hat Savings Plan up to the first 
6 percent of an associate’s compensation that exceeds the compensation limit specified by the Internal 
Revenue Code of 1986, as amended. 
Pursuant to ASC 715-30 we recognized expense of $3 million during 2008 in the consolidated statement of 
income associated with the partial termination of the qualified pension plan. In addition, we recognized 
$27 million in the consolidated statement of income during 2008 for a settlement loss associated with the 
payout to the participants who left the pension plan of the obligation held in their behalf. Included in the 
charge is the contribution of $24 million to complete funding of benefits that were distributed in 2008 to 
participants leaving the pension plan. 

Cincinnati Financial Corporation – 2010 10-K – Page 121 

 
Defined Benefit Pension Plan Assumptions 
Key assumptions used in developing the 2010 net pension obligation were a 5.85 percent discount rate for 
the qualified plan and a 5.55 percent discount rate for our SERP and rates of compensation increases 
ranging from 3.50 percent to 5.50 percent. To determine the discount rate for each plan, a hypothetical 
diversified portfolio of actual domestic Aa rated bonds were chosen to provide payments approximately 
matching the plan’s expected benefit payments. A single interest rate for each plan was determined based 
on the anticipated yield of the constructed portfolio. We decreased the rate by 0.25 percentage points for the 
qualified plan and by 0.55 percentage points for the SERP due to market interest rate conditions at year-end 
2010. Compensation increase assumptions reflect anticipated rates of inflation, real return on wage growth 
and merit and promotional increases. 
Key assumptions used in developing the 2010 net pension expense were a 6.10 percent discount rate; 
an 8.00 percent expected return on plan assets and rates of compensation increases ranging from 
4.00 percent to 6.00 percent. The 8.00 percent return on plan assets assumption is consistent with current 
expectations of inflation and based partially on the fact that our common stock holdings pay dividends. We 
believe this rate is representative of the expected long-term rate of return on these assets. These 
assumptions were consistent with the prior year, except that the discount rate was increased by 
0.10 percentage points due to market interest rate conditions at the beginning of the year. We based the 
rates of compensation increase on the company’s historical data. 
The weighted-average assumptions used to determine benefit obligations at December 31 follows:

We evaluate our pension plan assumptions annually and update them as necessary. The discount rate 
assumptions for our benefit obligation generally track with high grade corporate bond yields and yearly 
adjustments reflect any changes to those bond yields. We believe the expected return on plan assets is

The total recognized in net periodic benefit cost and other comprehensive income was $9 million, $25 million 
and $62 million for the years ended December 31, 2010, 2009 and 2008, respectively. The estimated costs 
to be amortized from AOCI into net periodic benefit cost over the next year for our plans are a $3 million 
actuarial loss and a $1 million prior service cost.  
Defined Benefit Pension Plan Assets 
The pension plan assets are managed to maximize total return over the long term while providing sufficient 
liquidity and current return to satisfy the cash flow requirements of the plan. The plan’s day-to-day 
investment decisions are managed by our internal investment department; however, overall investment 
strategies are agreed upon by our employee benefits committee.  
Excluding cash, during 2010 we allocated approximately 70 percent of the pension portfolio to highly 
observable domestic equity investments, which reflect the long-term time horizon of pension obligations. The 
remainder of the portfolio is allocated approximately 16 percent to domestic fixed-maturity investments and 
approximately 12 percent to taxable municipal bonds. The remaining 2 percent is allocated to preferred 
equities. At December 31, 2010, we had $9 million of cash on hand, with carrying value approximating fair 
value. Our shift to fixed maturities during the year was to increase the duration of the portfolio, diversify the 
types of credit risk and to better match our liability risks which is consistent with our strategy. Our corporate 
and municipal bond portfolio is investment grade. The plan does not engage in derivative transactions.  
Investments in securities traded on a national securities exchange are valued at the last reported sales price 
on the last business day of the year. Investments in securities that are traded in active markets are valued on 
quoted market prices at December 31, 2010 and 2009. Investments in securities that are not actively traded 
are valued based on pricing models for which the inputs have been corroborated by market data at 
December 31, 2010 and 2009.  
The plan, which ultimately determines fair value, categorized its financial instruments, based on the priority 
of the observable and market-based data for valuation technique, into a three-level fair value hierarchy. The 
fair value hierarchy gives the highest priority to quoted prices with readily available independent data in 
active markets for identical assets or liabilities (Level 1) and the lowest priority to unobservable market 
inputs (Level 3). When various inputs for measurement fall within different levels of the fair value hierarchy, 
the lowest observable input that has a significant impact on fair value measurement is used. 
Refer to Note 3, Fair Value Measurements, Page 114 for valuation techniques and categorization of financial 
instruments within the pension plan assets. The methods described may produce a fair value calculation that 
may not be indicative of net realizable value or reflective of future fair values. Furthermore, while we believe 
our valuation methods are appropriate and consistent with other market participants, the use of different 
methodologies or assumptions to determine the fair value of certain financial instruments could result in a 
different fair value measurement.

The following table illustrates the fair value hierarchy for those assets measured at fair value on a recurring 
basis for period ended December 31, 2010 and 2009. The pension plan does not have any assets 
categorized as Level 3. There have been no transfers between Level 1 and Level 2 for the period ended 
December 31, 2010 and 2009.

Our pension plan assets included 642,113 shares of the company’s common stock, which had a fair value of 
$20 million and $17 million at December 31, 2010 and 2009, respectively. The defined benefit pension plan 
did not purchase or sell any shares of our common stock during 2010 and 2009. The company paid 
$1 million in cash dividends on our common stock to the pension plan in both 2010 and 2009. 
On February 1, 2011, we contributed $35 million to our qualified plan. We also expect to pay $2 million to 
the SERP during 2011. We expect to make the following benefit payments for our qualified plan and SERP, 
reflecting expected future service:

STATUTORY ACCOUNTING INFORMATION (UNAUDITED) 

14.  
Insurance companies use statutory accounting practices (SAP) as prescribed by regulatory authorities. The 
primary differences between SAP and GAAP include: 
• 
• 
• 
•  deferred income taxes based on differences in statutory and taxable income. 
Statutory net income and capital and surplus are determined in accordance with SAP prescribed or permitted 
by insurance regulatory authorities for five legal entities, our insurance subsidiary and its four insurance 
subsidiaries. Statutory capital and surplus for our insurance subsidiary, The Cincinnati Insurance Company, 
includes capital and surplus of its four insurance subsidiaries. The statutory net income and statutory surplus 
are presented below:

TRANSACTIONS WITH AFFILIATED PARTIES 

COMMITMENTS AND CONTINGENT LIABILITIES 

15.  
We paid certain officers and directors, or insurance agencies of which they are shareholders, commissions of 
approximately $6 million, $6 million and $6 million on premium volume of approximately $36 million, 
$36 million and $38 million for 2010, 2009 and 2008, respectively. 
16.  
In the ordinary course of conducting business, the company and its subsidiaries are named as defendants in 
various legal proceedings. Most of these proceedings are claims litigation involving the company’s insurance 
subsidiaries in which the company is either defending or providing indemnity for third-party claims brought 
against insureds who are litigating first-party coverage claims. The company accounts for such activity 
through the establishment of unpaid loss and loss adjustment expense reserves. We believe that the 
ultimate liability, if any, with respect to such ordinary-course claims litigation, after consideration of 
provisions made for potential losses and costs of defense, is immaterial to our consolidated financial 
condition, results of operations and cash flows.  
The company and its subsidiaries also are occasionally involved in other legal actions, some of which assert 
claims for substantial amounts. These actions include, among others, putative class actions seeking 
certification of a state or national class. Such putative class actions have alleged, for example, improper 
reimbursement of medical providers paid under workers’ compensation insurance policies, erroneous coding 
of municipal tax locations and excessive premium charges for uninsured motorist coverage. The company’s 
insurance subsidiaries also are occasionally parties to individual actions in which extra-contractual damages, 
punitive damages or penalties are sought, such as claims alleging bad faith in the handling of 
insurance claims. From time to time, the company also becomes aware of incidents that could result in 
liability, with or without litigation or regulatory action, for example, data processing errors by third-party 
vendors servicing certain of our employee benefit plans.  
On a quarterly basis, we review these outstanding matters. Under current accounting guidance, we establish 
accruals when it is probable that a loss has been incurred and we can reasonably estimate its potential 
exposure. The company accounts for such probable and estimable losses, if any, through the establishment 
of legal expense reserves. Based on our quarterly review, we believe that our accruals for probable and 
estimable losses are reasonable and that the amounts accrued do not have a material effect on our 
consolidated financial condition or results of operations. However, if any one or more of these matters results 
in a judgment against us or settlement for an amount that is significantly greater than the amount accrued, 
the resulting liability could have a material effect on the company’s consolidated results of operations or 
cash flows. Based on our quarterly review, for any other matter for which the risk of loss is more than remote 
we are unable to reasonably estimate the potential loss or establish a reasonable range of loss. 
STOCK-BASED ASSOCIATE COMPENSATION PLANS 
17.  
We currently have four equity compensation plans that together permit us to grant various types of equity 
awards. We currently grant incentive stock options, non-qualified stock options, service-based restricted 
stock units and performance-based restricted stock units, including some with market-based performance 
objectives, under our shareholder-approved plans. We also have a Holiday Stock Plan that permits annual 
awards of one share of common stock to each full-time associate for each full calendar year of service up to 
a maximum of 10 shares. One of our equity compensation plans permits us to grant stock to our outside 
directors as a component of their annual compensation. 
Stock-based compensation cost after tax was $8 million, $7 million and $11 million for the years ended 
December 31, 2010, 2009 and 2008, respectively. Options exercised during the year ended December 31, 
2010 and 2009, had intrinsic value less than $1 million. The total intrinsic value of options exercised during 
the year ended December 31, 2008, was $1 million. (Intrinsic value is the market price less the exercise 
price.) Options vested during the year ended December 31, 2010, had total intrinsic value of $1 million. 
Options vested during the years ended 2009 and 2008 had intrinsic value less than $1 million. 
As of December 31, 2010, we had $11 million of unrecognized total compensation cost related to non-
vested stock options and restricted stock unit awards. That cost will be recognized over a weighted-average 
period of 1.8 years.  
Stock options are granted to associates at an exercise price that is equal to the fair value as reported on the 
NASDAQ Global Select Market for the grant date and are exercisable over 10-year periods. The stock options 

Cincinnati Financial Corporation – 2010 10-K – Page 125 

 
generally vest ratably over a three-year period. In determining the share-based compensation amounts, we 
estimate the fair value of each option granted on the date of grant using the binomial option-pricing model. 
We make assumptions in four areas to develop the binomial option-pricing model: 
•  Weighted-average expected term is based on historical experience of similar awards with consideration 

for current exercise trends.  

•  Expected volatility is based on our stock price over a historical period that approximates the 

expected term.  

•  Dividend yield is determined by dividing the annualized per share dividend by the stock price on the date 

of grant.  

•  Risk-free rates are the implied yield currently available on U.S. Treasury issues with a remaining term 

approximating the expected term.  

During 2010, we granted stock-based awards to associates and issued our common stock to eligible 
associates under our Holiday Bonus Plan. No stock based awards were granted to associates during 2009. 
The following weighted average assumptions were used for option grants issued during 2010 and 2008 in 
determining fair value: 

Weighted - average expected term
Expected volatility
Dividend yield
Risk-free rates
Weighted-average fair value of options granted during the period

The weighted-average remaining contractual life for exercisable awards as of December 31, 2010, was 
3.5 years. A total of 16.9 million shares are authorized to be granted under the shareholder-approved plans. 
At December 31, 2010, 6.0 million shares were available for future issuance under the plans. During 2009, 
our shareholders approved the Directors’ Stock Plan of 2009, which authorizes 300,000 shares to be 
granted to our directors. During 2010 we granted 31,310 shares of common stock to our directors for 
2009 board service fees. We currently issue new shares or use treasury shares for stock-based 
compensation award issues or exercises. 
Restricted Stock Units 
Service and performance-based restricted stock units are granted to associates at fair value of the shares on 
the date of grant less the present value of the dividends that holders of restricted stock units will not receive 
on the shares underlying the restricted stock units during the vesting period. Service-based restricted stock 
units cliff vest three years after the date of grant.  

Cincinnati Financial Corporation – 2010 10-K – Page 126 

 
 
 
If certain performance conditions are attained, performance-based restricted stock units vest on the first day 
of March after a three-calendar-year performance period. Quarterly, management reviews and determines 
the likelihood that the company will achieve the conditions for the outstanding groups of performance 
restricted stock units and recognizes related compensation costs in accordance with ASC 718, 
Compensation, Stock Compensation. 
We have market-based awards for which we recognize compensation costs in accordance with ASC 718. 
These awards vest according to the level of total shareholder return achieved compared to a peer group over 
a three-year period. These awards are valued using a Monte-Carlo valuation on the date of grant, which uses 
a risk-neutral framework to model future stock price movements based upon the risk-free rate of return, the 
volatility of each peer and the correlations of each peer being modeled. Compensation cost is recognized 
regardless of whether the market-based performance objective has been satisfied, resulting in shares not 
being issued. We make assumptions to develop the Monte-Carlo model as follows: 
•  Correlation coefficients are based upon the price data used to calculate the historical volatilities. 

The correlation coefficients are used to model the way in which each entity tends to move in relation to 
each other. 

•  Expected volatility is based on our stock price over a historical period that approximates the 

expected term. We have used the historical volatilities over a range of 2.76-2.86 years for 2010 grants 
and 3.13 years for 2008 grants. 

•  Dividend yield has been modeled assuming that the holder of the award is not entitled to receive 

dividends that are paid during the performance period. Dividend yield range from 5.41%-5.94% for 
2010 grants and 5.87% for 2008 grants. 

•  Risk-free rates are equal to the yield, as of the measurement date, of the zero-coupon U.S. Treasury bill 
that is commensurate with the performance period. Risk free rates used range from 1.43%-1.50% for 
2010 grants and 1.58% for 2008 grants.

SEGMENT INFORMATION 

18.  
We operate primarily in two industries, property casualty insurance and life insurance. We regularly review 
our reporting segments to make decisions about allocating resources and assessing performance:  
•  Commercial lines property casualty insurance  
•  Personal lines property casualty insurance  
•  Excess and Surplus lines property casualty insurance 
• 
• 
As discussed in Note 1, we revised our reportable segments during the fourth quarter of 2010 to establish a 
separate reportable segment for excess and surplus lines. This will allow readers to view this business in a 
manner similar to how it is managed internally when making operating decisions. This new segment includes 
results of The Cincinnati Specialty Underwriters Insurance Company and CSU Producer Resources. 
Historically, the excess and surplus lines results were reflected in Other. Prior period data included in this 
annual report has been adjusted to represent this new segment. 
We report as Other the non-investment operations of the parent company and its non-insurer subsidiary, 
CFC Investment Company. Also included in 2009 and 2008 results for this segment are the operations of a 
former subsidiary, CinFin Capital Management.  
Revenues come primarily from unaffiliated customers:  
•  All four insurance segments record revenues from insurance premiums earned. Life insurance segment 

revenues also include separate account investment management fees. 

• 

Fee revenues for the commercial and personal insurance segments primarily represent installment fees. 
Previously the fee revenues were reflected in Other. Prior period data included in this annual report has 
been adjusted to reflect this new presentation.  

Cincinnati Financial Corporation – 2010 10-K – Page 127 

 
•  Our investment operations’ revenues are pretax net investment income plus realized investment gains 

and losses.  

•  Other revenues are primarily finance/lease income.  
Income or loss before income taxes for each segment is reported based on the nature of that business 
area’s operations: 
• 

Income before income taxes for the insurance segments is defined as underwriting income or loss. 

o  For commercial lines, personal lines and excess and surplus insurance segments, we calculate 
underwriting income or loss by recording premiums earned minus loss and loss expenses and 
underwriting expenses incurred. 

o  For the life insurance segment, we calculate underwriting income or loss by recording premiums 
earned and separate account investment management fees, minus contract holders’ benefits 
and expenses incurred, plus investment interest credited to contract holders. 

• 

• 

Income before income taxes for the investment operations segment is net investment income plus 
realized investment gains and losses for investments of the entire company, minus investment interest 
credited to contract holders of the life insurance segment.  

Loss before income taxes for the Other category is primarily due to interest expense from debt of the 
parent company and operating expenses of our headquarters. 

Identifiable assets are used by each segment in its operations. We do not separately report the identifiable 
assets for the commercial, personal or excess and surplus lines segments because we do not use that 
measure to analyze the segments. We include all investment assets, regardless of ownership, in the 
investment operations segment.

* 

Revenues including realized investment gains and losses, which are integral to our financial results over the long term, may cause 
this value to fluctuate substantially because we have substantial discretion in the timing of investment sales. Also, applicable 
accounting standards require us to recognize gains and losses from certain changes in fair values of securities and embedded 
derivatives without actual realization of those gains and losses. We discuss realized investment gains for the past three years in 
Item 7, Investments Results of Operations, Page 75.

Item 9. 

Changes in and Disagreements with Accountants on 
Accounting and Financial Disclosure 
We had no disagreements with the independent registered public accounting firm on accounting and 
financial disclosure during the last two fiscal years.  
Item 9A.   Controls and Procedures  
Evaluation of Disclosure Controls and Procedures – The company maintains disclosure controls and 
procedures (as that term is defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 
1934, as amended (Exchange Act)). 
Any controls and procedures, no matter how well designed and operated, can provide only reasonable 
assurance of achieving the desired control objectives. The company’s management, with the participation of 
the company’s chief executive officer and chief financial officer, has evaluated the effectiveness of the 
design and operation of the company’s disclosure controls and procedures as of December 31, 2010. Based 
upon that evaluation, the company’s chief executive officer and chief financial officer concluded that the 
design and operation of the company’s disclosure controls and procedures provided reasonable assurance 
that the disclosure controls and procedures are effective to ensure that: 
• 

information required to be disclosed in the company’s reports under the Exchange Act is recorded, 
processed, summarized and reported within the time periods specified in the Securities and Exchange 
Commission’s rules and forms, and  

• 

such information is accumulated and communicated to the company’s management, including its chief 
executive officer and chief financial officer, as appropriate, to allow timely decisions regarding required 
disclosures.  

Changes in Internal Control over Financial Reporting – During the three months ended December 31, 2010, 
there were no changes in our internal controls over financial reporting that have materially affected, or are 
reasonably likely to materially affect, our internal control over financial reporting. Management’s Annual 
Report on Internal Control Over Financial Reporting and the Report of the Independent Registered Public 
Accounting Firm are set forth in Item 8, Pages 99 and 100. 
Item 9B.   Other Information 
None

This condensed financial information should be read in conjunction with the Consolidated Financial Statements and 
Notes included in Part II, Item 8, Page 105. 
Note to Schedule II: 
We have changed our presentation related to equity in net income of subsidiaries. We have reclassified dividends from 
subsidiaries in the condensed statements of income to be included within a single line, “Increase in equity of 
subsidiaries.” We have changed presentation in the condensed statements of cash flows to show separately “Dividends 
from subsidiaries” and “Increase in equity of subsidiaries” within cash flows from operating activities. We also have
