Exhibit 99.1

             Cincinnati Financial Corporation Summarizes Estimates
                       of Third-Quarter Hurricane Losses

        - Hurricane Jeanne catastrophe losses at approximately $8 million

  - Total third-quarter pretax catastrophe losses in range of $94 million, net
                                 of reinsurance


    CINCINNATI, Oct. 11 /PRNewswire-FirstCall/ -- Cincinnati Financial
Corporation (Nasdaq: CINF) today announced an estimate of $8 million for
pretax catastrophe losses resulting from Hurricane Jeanne and updated
estimates for prior storms. Including Jeanne, third-quarter pretax catastrophe
losses, net of reinsurance, now are estimated at $94 million. The impact of
these claims on the third-quarter property casualty combined ratio, after an
$11 million reinsurance reinstatement premium, would be approximately 13
percentage points. Earnings per share (after tax) would be reduced by
approximately 40 cents.



                                                       Reported  Loss Estimate
                                                        Claims     (pretax,
     Third-Quarter                   States Primarily  (through     net of
         Event           Dates          Affected       October 8) reinsurance)

    Hurricane Jeanne  September 25-27  Florida, Georgia    <800     $8 million

    Hurricane Frances September 3-8    Florida             <800    $12 million
    Tropical Storm    August 29-30     Virginia            <100     $1 million
    Gaston
    Hurricane Charley August 13-14     Florida, Georgia    <900    $23 million
    Wind Storm        July 12-14       Illinois          <1,100    $13 million


    The loss estimate for each event includes losses from claims received as
well as updated estimates of claims that have not yet been reported. The
company now anticipates losses before reinsurance from Hurricane Ivan of more
than $90 million.

    The company's reinsurance coverage protects against catastrophic events
such as wind and hail, hurricanes or earthquakes. Under the 2004 reinsurance
program, the company retains the first $25 million in losses arising from a
single event and 43 percent of losses from $25 million to $45 million. The
company retains only 5 percent of losses between $45 million and $500 million.
To restore affected layers of the property catastrophe reinsurance program
following Ivan, the company incurred a reinsurance reinstatement premium in
the third quarter. While the company participates in wind pools in Florida and
other affected states, it has received no information on which to develop
estimates of any potential assessments.

    Chairman and Chief Executive Officer John J. Schiff, Jr., CPCU, commented,
"Without question, storms have had a significant impact on third-quarter
results for The Cincinnati Insurance Companies and the insurance industry in
general. The bigger impact, however, has been on the lives of policyholders
throughout the Southeast. Our associates have been working diligently to serve
these policyholders and to help them move forward. Our policyholders can take
comfort in the financial strength that allows us to pay claims promptly and
fairly. Reinsurance is one element of that financial strength and we are
comfortable that the programs we have in place are appropriate for our
organization."

    Schiff noted, "Our estimate of total year-to-date catastrophe losses has
risen to $141 million, net of reinsurance. This estimate is above the $90
million to $100 million range we had assumed when developing our target
full-year 2004 GAAP combined ratio of 92 percent. Preliminary indications are
that strong profitability from our underlying business continued in the third
quarter. We will update our combined ratio guidance based on more complete
third-quarter information when we announce final results later this month."

    This is a "Safe Harbor" statement under the Private Securities Litigation
Reform Act of 1995. Certain forward-looking statements contained herein
involve potential risks and uncertainties. The company's future results could
differ materially from those discussed. Factors that could cause or contribute
to such differences include, but are not limited to:

     - unusually high levels of catastrophe losses due to changes in weather
       patterns, environmental events, terrorism incidents or other causes
     - ability to obtain adequate reinsurance on acceptable terms, amount of
       reinsurance purchased and financial strength of reinsurers
     - increased frequency and/or severity of claims
     - 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:
       - downgrade of the company's financial strength ratings,
       - concerns that doing business with the company is too difficult or
       - perceptions that the company's level of service is no longer a
         distinguishing characteristic in the marketplace
     - delays in the development, implementation, performance and benefits of
       technology projects and enhancements
     - inaccurate estimates or assumptions used for critical accounting
       estimates, including loss reserves
     - results and timely completion of assessment and remediation of internal
       controls for financial reporting under the Sarbanes-Oxley Act of 2002
     - recession or other economic conditions or regulatory, accounting or tax
       changes resulting in lower demand for insurance products
     - sustained decline in overall stock market values negatively affecting
       the company's equity portfolio, in particular a sustained decline in
       the market value of Fifth Third Bancorp (Fifth Third) shares, a
       significant equity holding
     - events that lead to a significant decline in the market value of a
       particular security and impairment of the asset
     - prolonged low interest rate environment or other factors that limit the
       company's ability to generate growth in investment income
     - insurance regulatory actions, legislation or court decisions that
       increase expenses or place the company at a disadvantage in the
       marketplace
     - adverse outcomes from litigation or administrative proceedings
     - not receiving an exemptive order pursuant to the Investment Company Act
       of 1940 from the SEC, and the resulting changes that would be required
       in the company's operations


    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 recent measures affecting corporate financial reporting and
governance. The ultimate changes and eventual effects, if any, of these
initiatives are uncertain.

    Readers are cautioned that the company undertakes no obligation to review
or update the forward-looking statements included in this material.
