Fair Value of Financial Instruments

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


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


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


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

The Company utilizes one nationally recognized pricing service to estimate the majority of its available-for-sale investment portfolio’s fair value. The Company obtains one price per security and the processes and control procedures employed by the Company are designed to ensure the value is accurately recorded on an unadjusted basis. Through discussions with the pricing service, the Company gains an understanding of the methodologies used to price the different types of securities, that the data and the valuation methods utilized are appropriate and consistently applied, and that the assumptions are reasonable and representative of fair value. To validate the reasonableness of the valuations obtained from the pricing service, the Company compares to other fair value pricing information gathered from other independent pricing sources. At March 31, 2015 and December 31, 2014, the Company did not adjust any of the prices received from the pricing service.

Transfers between level categorizations may occur due to changes in the availability of market observable inputs. Transfers in and out of level categorizations are reported as having occurred at the beginning of the quarter in which the transfer occurred. There were no transfers between level categorizations during the three months ended March 31, 2015 and 2014.

The following sections describe the valuation methods used by the Company for each type of financial instrument it holds that are carried at fair value:

Fixed Maturities

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

Equities

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

Other Invested Assets

Included in other invested assets are two international funds (“the funds”) that invest in equity securities of foreign issuers and are managed by third party investment managers. The funds had a fair value of $80.5 million and $72.9 million at March 31, 2015 and December 31, 2014, respectively, which was determined using each fund’s net asset value. The Company employs procedures to assess the reasonableness of the fair value of the funds including obtaining and reviewing each fund’s audited financial statements. There are no unfunded commitments related to the funds. The Company may not sell its investment in the funds; however, the Company may redeem all or a portion of its investment in the funds at net asset value per share with the appropriate prior written notice. Due to the Company’s ability to redeem its investment in the funds at net asset value per share at the measurement date, the funds have been disclosed in Level 2.

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

The following tables set forth the Company’s available-for-sale investments within the fair value hierarchy at March 31, 2015 and December 31, 2014:

The following sections describe the valuation methods used by the Company for each type of financial instrument it holds that is not measured at fair value but for which fair value is disclosed:

Financial Instruments Disclosed, But Not Carried, At Fair Value

Other Invested Assets

Included in other invested assets are common stock of the Federal Home Loan Bank of Cincinnati ("FHLB") and the Trust Securities. The Trust Securities and FHLB common stock are carried at cost, which approximates fair value. The fair value of the FHLB common stock at March 31, 2015 was $4.8 million and the fair value of the Trust Securities was $0.5 million. The investments have been placed in Level 3 of the fair value hierarchy.

Notes Receivable from Affiliate

In May 2009, the Company entered into two separate credit agreements with State Automobile Mutual Insurance Company (“State Auto Mutual") pursuant to which it loaned State Auto Mutual a total of $70.0 million. The Company estimates the fair value of the notes receivable from affiliate using market quotations for U.S. treasury securities with similar maturity dates and applies an appropriate credit spread. Consequently this has been placed in Level 2 of the fair value hierarchy.



($ millions, except interest rates)	March 31, 2015						December 31, 2014
	Carrying value		Fair value		Interest rate		Carrying value		Fair value		Interest rate
Notes receivable from affiliate	$	70.0	$	76.4	7.00	%	$	70.0	$	74.6	7.00	%

Notes Payable

Included in notes payable are the FHLB Loan and Subordinated Debentures. The Company estimates the fair value of the FHLB Loan by discounting cash flows using a borrowing rate currently available to the company for a loan with similar terms. This has been placed in Level 3 of the fair value hierarchy. The carrying amount of the Subordinated Debentures approximates its fair value as the interest rate adjusts quarterly and has been disclosed in Level 3.



($ millions, except interest rates)	March 31, 2015						December 31, 2014
	Carrying value		Fair Value		Interest rate		Carrying value		Fair value		Interest rate
FHLB Loan due 2033: issued $85.0, July 2013 with fixed interest	$	85.3	$	86.5	5.03	%	$	85.3	$	86.4	5.03	%
Affiliate Subordinated Debentures due 2033: issued $15.5, May 2003 with variable interest	15.5		15.5		4.46	%	15.5		15.5		4.44	%
Total notes payable	$	100.8	$	102.0			$	100.8	$	101.9
