Significant Accounting Policies [Abstract]
Significant Accounting Policies	Significant Accounting Policies Basis of Presentation The accompanying unaudited consolidated financial statements of FBL Financial Group, Inc. (we or the Company) have been prepared in accordance with U.S. generally accepted accounting principles (GAAP) for interim financial information and the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do not include all of the information and notes required by GAAP for complete financial statements. Our financial statements include all adjustments (consisting of normal recurring accruals) necessary for a fair presentation of our financial position and results of operations. Operating results for the nine-month period ended September 30, 2015 are not necessarily indicative of the results that may be expected for the year ending December 31, 2015 . We encourage you to refer to our consolidated financial statements and notes for the year ended December 31, 2014 included in our Annual Report on Form 10-K for a complete description of our material accounting policies. Also included in the Form 10-K is a description of areas of judgments and estimates and other information necessary to understand our financial position and results of operations. Recent Accounting Pronouncements In May 2014, the Financial Accounting Standards Board (FASB) issued guidance that outlines a single comprehensive model for entities to use in accounting for revenue arising from contracts with customers, which supersedes most current revenue recognition guidance, including industry-specific guidance. Although insurance contracts are specifically excluded from the scope of this guidance, almost all entities will be affected to some extent by the significant increase in required disclosures. The new guidance is based on the principle that an entity should recognize revenue to reflect the transfer of goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. The guidance also requires additional disclosure about the nature, amount, timing and uncertainty of revenue and cash flows arising from customer contracts, including significant judgments and changes in judgments and assets recognized from costs incurred to fulfill a contract. Entities have the option of using either a full retrospective or a modified retrospective approach for the adoption of the new standard, which becomes effective for fiscal years beginning after December 15, 2017; early adoption is not permitted. We are currently evaluating the impact of this new guidance on our consolidated financial statements. In February 2015, the FASB issued guidance that amends existing consolidation guidance. The new guidance modifies the consolidation framework for certain investment entities and all limited partnerships. It also eliminates certain criteria used to determine whether fees paid to a decision maker are a variable interest. The amendment allows for either a full retrospective or modified approach at adoption of the new standard, which becomes effective for fiscal years beginning after December 15, 2015. Early adoption is permitted, including adoption in an interim period. If an entity early adopts the amendments in an interim period, any adjustments should be reflected as of the beginning of the fiscal year that includes that interim period. We are currently evaluating the impact of this new guidance on our consolidated financial statements.

The non-credit loss component of OTTI losses for corporate and other asset-backed securities were in an unrealized gain position at September 30, 2015 and December 31, 2014 due to increases in estimated fair value subsequent to initial recognition of non-credit losses on such securities.

We do not have plans to sell or believe we will be required to sell any of our temporarily-impaired fixed maturities before recovery of their amortized cost basis. The following summarizes the more significant unrealized losses of fixed maturities and equity securities by investment category as of September 30, 2015 . Corporate securities: The largest unrealized losses were in the energy sector ( $142.3 million carrying value and $25.4 million unrealized loss) and the basic industrial sector ( $126.6 million carrying value and $19.5 million unrealized loss). The largest unrealized losses in the energy sector were in the oil field services ( $32.5 million carrying value and $12.8 million unrealized loss) and energy-independent ( $54.7 million carrying value and $7.2 million unrealized loss) sub-sectors. The largest unrealized losses in the basic industrial sector were in the metal/mining ( $62.3 million carrying value and $14.5 million unrealized loss) and the chemicals ( $47.1 million carrying value and $4.6 million unrealized loss) sub-sectors. The majority of losses were primarily attributable to credit spread widening across the energy sector and metal/mining sub-sectors associated with sharp declines in commodity prices. Residential mortgage-backed securities: The unrealized losses on residential mortgage-backed securities were primarily due to continued uncertainty regarding mortgage defaults on Alt-A loans. We purchased most of these investments at a discount to their face amount and the contractual cash flows of these investments are based on mortgages and other assets backing the securities. Other asset-backed securities: The unrealized losses on other asset-backed securities were primarily due to market concerns regarding defaults on subprime mortgages and home equity loans. We purchased most of these investments at a discount to their face amount and the contractual cash flows of these investments are based on mortgages and other assets backing the securities. State, municipal and other governments: The unrealized losses on state, municipal and other governments were primarily due to general spread widening relative to spreads at which we acquired the bonds. Equity securities: Our gross unrealized losses on equity securities were on investment grade non-redeemable perpetual preferred securities within the finance sector. These securities provide periodic cash flows, contain call features and are similarly rated and priced like other long-term callable bonds and are evaluated for OTTIs similar to fixed maturities. The decline in fair value is primarily due to market concerns regarding the finance sector. We have evaluated the near-term prospects of our equity securities in relation to the severity and duration of their impairment as well as our intent and ability to hold these investments until recovery of fair value, and have concluded they are not other-than-temporarily impaired. Excluding mortgage- and asset-backed securities, no securities from the same issuer had an aggregate unrealized loss in excess of $3.7 million at September 30, 2015 , with the largest unrealized loss from an energy service provider. With respect to mortgage- and asset-backed securities not backed by the United States Government, our largest aggregate unrealized loss from the same issuer at September 30, 2015 was $3.7 million , consisting of two different securities that are backed by different pools of Alt-A residential mortgage loans. Both securities are rated non-investment grade and the largest unrealized loss totaled $2.2 million . The carrying values of all our investments are reviewed on an ongoing basis for credit deterioration. When our review indicates a decline in fair value for a fixed maturity security is an OTTI and we do not intend to sell or believe we will be required to sell the security before recovery of our amortized cost, a specific write down is charged to earnings for the credit loss and a specific charge is recognized in accumulated other comprehensive income for the non-credit loss component. If we intend to sell or believe we will be required to sell a fixed maturity security before its recovery, the full amount of the impairment write down to fair value is charged to earnings. For all equity securities, the full amount of an OTTI write down is recognized as a realized loss on investments in the consolidated statements of operations and the new cost basis for the security is equal to its fair value. We monitor the financial condition and operations of the issuers of fixed maturities and equity securities that could potentially have a credit impairment that is an OTTI. In determining whether or not an unrealized loss is an OTTI, we review factors such as: • historical operating trends; • business prospects; • status of the industry in which the company operates; • analyst ratings on the issuer and sector; • quality of management; • size of unrealized loss; • level of current market interest rates compared to market interest rates when the security was purchased; and • length of time the security has been in an unrealized loss position. In order to determine the credit and non-credit impairment loss for fixed maturities, every quarter we estimate the future cash flows we expect to receive over the remaining life of the instrument as well as review our plans to hold or sell the instrument. Significant assumptions regarding the present value of expected cash flows for each security are used when an OTTI occurs and there is a non-credit portion of the unrealized loss that won't be recognized in earnings. Our assumptions for residential mortgage-backed securities, commercial mortgage-backed securities and other asset-backed securities include collateral pledged, guarantees, vintage, anticipated principal and interest payments, prepayments, default levels, severity assumptions, delinquency rates and the level of nonperforming assets for the remainder of the investments' expected term. We use a single best estimate of cash flows approach and use the effective yield prior to the date of impairment to calculate the present value of cash flows. Our assumptions for corporate and other fixed maturities include anticipated principal and interest payments and an estimated recovery value, generally based on a percentage return of the current fair value. After an OTTI write down of all equity securities and any fixed maturities with a credit-only impairment, the cost basis is not adjusted for subsequent recoveries in fair value. For fixed maturities for which we can reasonably estimate future cash flows after a write down, the discount or reduced premium recorded, based on the new cost basis, is amortized over the remaining life of the security. Amortization in this instance is computed using the prospective method and the current estimate of the amount and timing of future cash flows .

As discussed above, the non-credit portion of the losses have been recognized in other comprehensive income (loss). (2) Amount represents credit-related losses recognized for real estate, other investments and fixed maturities written down to fair value through income. Proceeds from sales of fixed maturities totaled $88.3 million during the nine months ended September 30, 2015 and $47.5 million during the nine months ended September 30, 2014 . The realized gain on securities and indebtedness of related parties relates to a partnership investment's underlying asset sold at a gain and the dissolution of the partnership during 2015. Realized gains and losses on sales of investments are determined on the basis of specific identification. Mortgage Loans Our mortgage loan portfolio consists principally of commercial mortgage loans that we have originated. Our lending policies require that the loans be collateralized by the value of the related property, establish limits on the amount that can be loaned to one borrower and require diversification by geographic location and collateral type. We originate loans with an initial loan-to-value ratio that provides sufficient excess collateral to absorb losses should we be required to foreclose and take possession of the collateral. In order to identify impairment losses, management maintains and regularly reviews a watch list of mortgage loans that have heightened risk. These loans may include those with borrowers delinquent on contractual payments, borrowers experiencing financial difficulty, increases in rental real estate vacancies and significant declines in collateral value. We evaluate each of our mortgage loans individually and establish an estimated loss, if needed, for each impaired loan identified. An estimated loss is needed for loans for which we do not believe we will collect all amounts due according to the contractual terms of the respective loan agreements. Any loan delinquent on contractual payments is considered non-performing. At September 30, 2015 and December 31, 2014 , there were no non-performing loans over 90 days past due on contractual payments. Interest income is accrued on impaired loans to the extent it is deemed collectible (delinquent less than 90 days) and the loan continues to perform under its original or restructured contractual terms. Interest income on non-performing loans is generally recognized on a cash basis. Once mortgage loans are classified as non-accrual loans, the resumption of the interest accrual would commence only after all past-due interest has been collected or the mortgage loan has been restructured such that the collection of interest is considered likely.

We assess loan modifications on a loan-by-loan basis to evaluate whether a troubled debt restructuring has occurred. Generally, the types of concessions include: reduction of the contractual interest rate to a below-market rate, extension of the maturity date and/or a reduction of accrued interest. The amount, timing and extent of the concession granted is considered in determining if an impairment loss is needed for the restructuring. There were no loan modifications during the first three quarters of 2015 or of 2014. Variable Interest Entities We evaluate our variable interest entity (VIE) investees to determine whether the level of our direct ownership interest, our rights to manage operations or our obligation to provide ongoing financial support are such that we are the primary beneficiary of the entity, and would therefore be required to consolidate it for financial reporting purposes. None of our VIE investees were required to be consolidated for any reporting periods presented in this Form 10-Q.

Other At September 30, 2015, we had committed to provide $35.2 million of additional funds for limited partnerships and limited liability companies in which we invest. Derivative Instruments We are not significantly involved in hedging activities and have limited exposure to derivatives. We do not apply hedge accounting to any of our derivative positions. Derivative assets, which are primarily reported in reinsurance recoverable and other investments, totaled $4.2 million at September 30, 2015 and $7.1 million at December 31, 2014 . At September 30, 2015, we had master netting agreements with counterparties covering cash collateral payable totaling $0.4 million . This amount was invested and included in the consolidated balance sheets with corresponding amounts netted against the derivative instruments. We also received collateral of $0.5 million at September 30, 2015 which is held in a separate custodial account and not recorded on the balance sheet. Our derivative assets consist of derivatives embedded within our modified coinsurance agreements and call options which provide an economic hedge for our index annuity contracts. Derivative liabilities totaled $8.5 million at September 30, 2015 and $8.7 million at December 31, 2014 and include derivatives embedded within our index annuity contracts and derivatives embedded within our modified coinsurance agreements. The net gain recognized on these derivatives is included in net investment income and interest sensitive benefits. Net gain (loss) recognized on these derivatives totaled $(2.0) million for the quarter ended September 30, 2015 and $(0.1) million for the same period in 2014 and totaled $(2.1) million for the nine months ended September 30, 2015 and $1.6 million for the same period in 2014 .

As not all financial instruments are actively traded, various valuation methods may be used to estimate fair value. These methods rely on observable market data and where observable market data is not available, the best information available. Significant judgment may be required to interpret the data and select the assumptions used in the valuation estimates, particularly when observable market data is not available. In the discussion that follows, we have ranked our financial instruments by the level of judgment used in the determination of the fair values presented above. The levels are defined as follows: • Level 1 - Fair values are based on unadjusted quoted prices in active markets for identical assets or liabilities. • Level 2 - Fair values are based on inputs, other than quoted prices from active markets, that are observable for the asset or liability, either directly or indirectly. • Level 3 - Fair values are based on significant unobservable inputs for the asset or liability. In certain cases, the inputs used to measure fair value may fall into different levels of the fair value hierarchy. In such cases, a financial instrument's level within the fair value hierarchy is based on the lowest level of input that is significant to the fair value measurement. Our assessment of the significance of a particular input to the fair value measurement in its entirety requires judgment and considers factors specific to the financial instrument. From time to time there may be movements between levels as inputs become more or less observable, which may depend on several factors including the activity of the market for the specific security, the activity of the market for similar securities, the level of risk spreads and the source from which we obtain the information. Transfers into or out of any level are measured as of the beginning of the period. The following methods and assumptions were used in estimating the fair value of our financial instruments: Fixed maturities: Level 1 fixed maturities consist of U.S. Treasury issues that are actively traded, allowing us to use current market prices as an estimate of their fair value. Level 2 fixed maturities consist of corporate, mortgage- and asset-backed, United States Government agencies, state and municipal and private placement corporate securities with observable market data, and in some circumstances recent trade activity. When quoted prices of identical assets in active markets are not available, our first priority is to obtain prices from third party pricing vendors. We have regular interaction with these vendors to ensure we understand their pricing methodologies and to confirm they are utilizing observable market information. Their methodologies vary by asset class and include inputs such as estimated cash flows, benchmark yields, reported trades, credit quality, industry events and economic events. Fixed maturities with validated prices from pricing services, which includes the majority of our public fixed maturities in all asset classes, are generally reflected in Level 2. Also included in Level 2 are private placement corporate bonds where quoted market prices are not available, for which an internal model using substantially all observable inputs or a matrix pricing valuation approach is used. In the matrix approach, securities are grouped into pricing categories that vary by sector, rating and average life. Each pricing category is assigned a risk spread based on studies of observable public market data. The expected cash flows of the security are then discounted back at the current Treasury curve plus the appropriate risk spread. Level 3 fixed maturities include corporate, mortgage- and asset-backed, United States Government agencies and private placement corporate securities for which there is little or no current market data available. We use external pricing sources, or if prices are not available we will estimate fair value internally. Fair values of private corporate investments in Level 3 are determined by reference to the public market, private transactions or valuations for comparable companies or assets in the relevant asset class when such amounts are available. For other securities where an exit price based on relevant observable inputs is not obtained, the fair value is determined using a matrix calculation. Fair values estimated through the use of matrix pricing methods rely on an estimate of credit spreads to a risk-free U.S. Treasury yield. Selecting the credit spread requires judgment based on an understanding of the security and may include a market liquidity premium. Our selection of comparable companies as well as the level of spread requires significant judgment. Increases in spreads used in our matrix models, or those used to value comparable companies, will result in a decrease in discounted cash flows used, and accordingly in the estimated fair value of the security. We obtain fixed maturity fair values from a variety of external independent pricing services, including brokers, with access to observable data including recent trade information, if available. In certain circumstances in which an external price is not available for a Level 3 security, we will internally estimate its fair value. Our process for evaluation and selection of the fair values includes: • We follow a “pricing waterfall” policy, which establishes the pricing source preference for a particular security or security type. The order of preference is based on our evaluation of the valuation methods used, the source's knowledge of the instrument and the reliability of the prices we have received from the source in the past. Our valuation policy dictates that fair values are initially sought from third party pricing services. If our review of the prices received from our preferred source indicates an inaccurate price, we will use an alternative source within the waterfall and document the decision. In the event that fair values are not available from one of our external pricing services or upon review of the fair values provided it is determined that they may not be reflective of market conditions, those securities are submitted to brokers familiar with the security to obtain non-binding price quotes. Broker quotes tend to be used in limited circumstances such as for newly issued, private placement corporate bonds and other instruments that are not widely traded. For those securities for which an externally provided fair value is not available, we use cash flow modeling techniques to estimate fair value. • We evaluate third party pricing source estimation methodologies to assess whether they will provide a fair value which approximates a market exit price. • We perform an overall analysis of portfolio fair value movement against general movements in interest rates and spreads. • We compare period-to-period price trends to detect unexpected price fluctuation based on our knowledge of the market and the particular instrument. As fluctuations are noted, we will perform further research which may include discussions with the original pricing source or other external sources to ensure we are in agreement with the valuation. • We compare prices between different pricing sources for unusual disparity. • We meet at least quarterly with our Investment Committee, the group that oversees our valuation process, to discuss valuation practices and observations during the pricing process. Equity securities: Level 1 equity securities consist of listed common stocks and mutual funds that are actively traded, allowing us to use current market prices as an estimate of their fair value. Level 2 equity securities consist of common stock issued by the Federal Home Loan Bank of Des Moines (FHLB), with estimated fair value based on the current redemption value of the shares and non-redeemable preferred stock. Estimated fair value is obtained from external pricing sources using a matrix pricing approach. Level 3 equity securities consist of non-redeemable preferred stock for which no active market exists, and fair value estimates for these securities is based on the values of comparable securities which are actively traded. Increases in spreads used in our matrix models, or those used to value comparable companies, will result in a decrease in discounted cash flows used, and accordingly in the estimated fair value of the security. In the case where external pricing services are used for certain Level 1 and Level 2 equity securities, our review process is consistent with the process used to determine the fair value of fixed maturities discussed above. Mortgage loans: Mortgage loans are not measured at fair value on a recurring basis. Mortgage loans are a Level 3 measurement as there is no current market for the loans. The fair value of our mortgage loans is estimated internally using a matrix pricing approach. Along with specific loan terms, two key management assumptions are required including the risk rating of the loan (our current rating system is A-highest quality, B-moderate quality, C-low quality, W-watch or F-foreclosure) and estimated spreads for new loans over the U.S. Treasury yield curve. Spreads are updated quarterly and loans are reviewed and rated annually with quarterly adjustments should significant changes occur. Our determination of each loan's risk rating as well as selection of the credit spread requires significant judgment. A higher risk rating, as well as an increase in spreads, would result in a decrease in discounted cash flows used, and accordingly the fair value of the loan. Policy loans: Policy loans are not measured at fair value on a recurring basis. Policy loans are a Level 3 measurement as there is no current market since they are specifically tied to the underlying insurance policy. The loans are relatively risk free as they cannot exceed the cash surrender value of the insurance policy. Fair values are estimated by discounting expected cash flows using a risk-free interest rate based on the U.S. Treasury curve. An increase in the risk-free interest rate would result in a decrease in discounted cash flows used, and accordingly the fair value of the loan. Other investments: Level 2 other investments include call options with fair values based on counterparty market prices adjusted for a credit component of the counterparty, net of collateral received. Cash, cash equivalents and short-term investments: Level 1 cash, cash equivalents and short-term investments are highly liquid instruments for which historical cost approximates fair value. Reinsurance recoverable: Level 2 reinsurance recoverable includes embedded derivatives in our modified coinsurance contracts under which we cede or assume business. Fair values of these embedded derivatives are based on the difference between the fair value and the cost basis of the underlying fixed maturities, which are valued consistent with the discussion of fixed maturities above. Assets held in separate accounts: Level 1 assets held in separate accounts consist of mutual funds that are actively traded, allowing us to use current market prices as an estimate of their fair value. Future policy benefits, supplemental contracts without life contingencies and advance premiums and other deposits : Level 3 policy-related financial instruments of investment-type contracts are those not involving significant mortality or morbidity risks. No active market exists for these contracts and they are not measured at fair value on a recurring basis. Fair values for our insurance contracts, other than investment-type contracts, are not required to be disclosed. Fair values for our investment-type contracts with expected maturities, including deferred annuities, funding agreements and supplementary contracts, are determined using discounted cash flow valuation techniques based on current interest rates adjusted to reflect our credit risk and an additional provision for adverse deviation. For certain deposit liabilities with no defined maturities and no surrender charges, including pension-related deposit administration funds, advance premiums and other deposits, fair value is the account value or amount payable on demand. Significant judgment is required in selecting the assumptions used to estimate the fair values of these financial instruments. For contracts with known maturities, increases in current rates will result in a decrease in discounted cash flows and a decrease in the estimated fair value of the policy obligation. Certain annuity contracts include embedded derivatives and are measured at fair value on a recurring basis. These embedded derivatives are a Level 3 measurement. The fair value of the embedded derivatives is based on the discounted excess of projected account values (including a risk margin) over projected guaranteed account values. The key unobservable inputs required in the projection of future values which require management judgment include the risk margin as well as the credit risk of our company. Should the risk margin increase or the credit risk decrease, the discounted cash flows and the estimated fair value of the obligation will increase. Long-term debt: Long-term debt is not measured at fair value on a recurring basis. Long-term debt is a Level 3 measurement. The fair value of our outstanding debt is estimated using a discounted cash flow method based on the market's assessment or our current incremental borrowing rate for similar types of borrowing arrangements adjusted, as needed, to reflect our credit risk. Our selection of the credit spread requires significant judgment. A decrease in the spread will increase the estimated fair value of the outstanding debt. Other liabilities: Level 2 other liabilities include the embedded derivatives in our modified coinsurance contracts under which we cede business. Fair values for the embedded derivatives are based on the difference between the fair value and the cost basis of the underlying fixed maturities. Liabilities related to separate accounts: Separate account liabilities are not measured at fair value on a recurring basis. Level 3 separate account liabilities' fair value is based on the cash surrender value of the underlying contract, which is the cost we would incur to extinguish the liability.

Transfers out of Level 3 include those assets that we are now able to obtain pricing from a third party pricing vendor that uses observable inputs. The fair values of newly issued securities often require additional estimation until a market is created, generally within a few months after issuance. Once a market is created, as was the case for the majority of the security transfers out of the Level 3 category above, Level 2 valuation sources become available. There were no transfers between Level 1 and Level 2 during the periods presented above.

Segment Information [Abstract]
Segment Information	Segment Information We analyze operations by reviewing financial information regarding our primary products that are aggregated into the Annuity and Life Insurance product segments. In addition, our Corporate and Other segment includes various support operations, corporate capital and other product lines that are not currently underwritten by the Company. We analyze our segment results based on pre-tax operating income. Accordingly, income taxes are not allocated to the segments. In addition, operating results are reported net of transactions between the segments. Operating income represents net income excluding the impact of realized gains and losses on investments and changes in net unrealized gains and losses on derivatives. We use operating income, in addition to net income, to measure our performance since realized gains and losses on investments and the change in net unrealized gains and losses on derivatives can fluctuate greatly from quarter to quarter. A view of our operating performance without the impact of these items enhances the analysis of our results. We use operating income for goal setting, determining short-term incentive compensation and evaluating performance on a basis comparable to that used by many in the investment community.

Our investment in equity method investees, the related equity income and interest expense are attributable to the Corporate and Other segment. Expenditures for long-lived assets were not significant during the periods presented above. Goodwill at September 30, 2015 and December 31, 2014 was allocated among the segments as follows: Annuity ( $3.9 million ) and Life Insurance ( $6.1 million ). Premiums collected, which is not a measure used in financial statements prepared according to GAAP, includes premiums received on life insurance policies and deposits on annuities and universal life-type products. Net premiums collected totaled $184.0 million for the quarter ended September 30, 2015 and $149.4 million for the same period in 2014 . Net premiums collected totaled $508.4 million for the nine months ended September 30, 2015 and $504.4 million for the same period in 2014 . Under GAAP, premiums on whole life and term life policies are recognized as revenues over the premium-paying period and reported in the Life Insurance segment. The following chart provides a reconciliation of life insurance premiums collected to those reported in the GAAP financial statements.

We do not have plans to sell or believe we will be required to sell any of our temporarily-impaired fixed maturities before recovery of their amortized cost basis. The following summarizes the more significant unrealized losses of fixed maturities and equity securities by investment category as of September 30, 2015 . Corporate securities: The largest unrealized losses were in the energy sector ( $142.3 million carrying value and $25.4 million unrealized loss) and the basic industrial sector ( $126.6 million carrying value and $19.5 million unrealized loss). The largest unrealized losses in the energy sector were in the oil field services ( $32.5 million carrying value and $12.8 million unrealized loss) and energy-independent ( $54.7 million carrying value and $7.2 million unrealized loss) sub-sectors. The largest unrealized losses in the basic industrial sector were in the metal/mining ( $62.3 million carrying value and $14.5 million unrealized loss) and the chemicals ( $47.1 million carrying value and $4.6 million unrealized loss) sub-sectors. The majority of losses were primarily attributable to credit spread widening across the energy sector and metal/mining sub-sectors associated with sharp declines in commodity prices. Residential mortgage-backed securities: The unrealized losses on residential mortgage-backed securities were primarily due to continued uncertainty regarding mortgage defaults on Alt-A loans. We purchased most of these investments at a discount to their face amount and the contractual cash flows of these investments are based on mortgages and other assets backing the securities. Other asset-backed securities: The unrealized losses on other asset-backed securities were primarily due to market concerns regarding defaults on subprime mortgages and home equity loans. We purchased most of these investments at a discount to their face amount and the contractual cash flows of these investments are based on mortgages and other assets backing the securities.

Transfers out of Level 3 include those assets that we are now able to obtain pricing from a third party pricing vendor that uses observable inputs. The fair values of newly issued securities often require additional estimation until a market is created, generally within a few months after issuance. Once a market is created, as was the case for the majority of the security transfers out of the Level 3 category above, Level 2 valuation sources become available. There were no transfers between Level 1 and Level 2 during the periods presented above.

[1]	Transfers into Level 3 represent assets previously priced using an external pricing service with access to observable inputs no longer available and therefore, were priced using non-binding broker quotes. Transfers out of Level 3 include those assets that we are now able to obtain pricing from a third party pricing vendor that uses observable inputs. The fair values of newly issued securities often require additional estimation until a market is created, generally within a few months after issuance. Once a market is created, as was the case for the majority of the security transfers out of the Level 3 category above, Level 2 valuation sources become available. There were no transfers between Level 1 and Level 2 during
