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 three months ended March 31, 2021 are not necessarily indicative of the results that may be expected for the year ending December 31, 2021, especially when considering the risks and uncertainties associated with the novel coronavirus ("COVID-19") and the impact it may have on our business, results of operations and financial condition. We encourage you to refer to the notes to our consolidated financial statements included in Item 8 of our Form 10-K for the year ended December 31, 2020 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. Our estimates and assumptions could change in the future as more information becomes known about the impact of COVID-19. Our results of operations and financial condition may also be impacted by evolving regulatory, legislative and accounting interpretations and guidance. Subsequent Event – Amendment to Merger Agreement – Proposed Affiliate Acquisition of Outstanding Shares On May 2, 2021, the Company entered into an amendment (the Merger Agreement Amendment) to the Agreement and Plan of Merger, dated as of January 11, 2021 (the Original Agreement and, the Original Agreement as amended by the Merger Agreement Amendment, the Merger Agreement), by and among the Company, Farm Bureau Property & Casualty Insurance Company, an Iowa domiciled stock property and casualty insurance company (FBPCIC) and 5400 Merger Sub, Inc., an Iowa corporation (Merger Sub). Pursuant to the Merger Agreement, FBPCIC will acquire all of the outstanding Class A common shares, without par value, and Class B common shares, without par value (collectively, the Common Shares), of the Company that are not currently owned or controlled by FBPCIC or the Iowa Farm Bureau Federation, an Iowa non-profit corporation (IFBF), for $61.00 per share in cash. The Merger Agreement Amendment provided for an increase in the consideration to be received in exchange for the Common Shares in the amount of $5.00 per share, from $56.00 per share under the Original Agreement. IFBF and FBPCIC currently own approximately 61% of the outstanding Common Shares. The Merger Agreement provides for the merger of Merger Sub with and into the Company, with the Company surviving the merger (the Merger). Consummation of the Merger is subject to certain specified closing conditions, including approval by the Company’s shareholders. The Company’s adjourned special meeting of shareholders to approve the proposal to adopt the Merger Agreement is expected to re-convene on May 21, 2021. Also on May 2, 2021, FBPCIC, IFBF and Merger Sub entered into an amendment (the Rollover Agreement Amendment) to the Rollover Agreement, dated as of January 11, 2021 (as amended by the Rollover Agreement Amendment, the Rollover Agreement) by and among the same parties. Pursuant to the Rollover Agreement, FBPCIC and IFBF will contribute to Merger Sub all of their Common Shares in exchange for the number of shares of common stock of Merger Sub set forth therein, and to fund the Merger consideration, FBPCIC will contribute approximately $528 million in cash to Merger Sub in exchange for shares of common stock of Merger Sub and IFBF will contribute approximately $47 million in cash to Merger Sub in exchange for shares of preferred stock of Merger Sub. With respect to Merger Sub, under the terms of the Merger Agreement, at the effective time of the Merger, the Common Shares held by Merger Sub will automatically be cancelled and will cease to exist, each common share of Merger Sub will be converted into one common share of the surviving corporation and each preferred share of Merger Sub will be converted into one share of newly-designated Series C Cumulative Non-Voting Preferred Stock of the surviving corporation. At the effective time of the Merger, the Common Shares that are not currently controlled by FBPCIC or IFBF (other than shares held by the Company in treasury or by any wholly-owned Company subsidiary, or held by Merger Sub or FBPCIC, or held by holders who have properly exercised dissenters’ rights under applicable Iowa law) will be converted into the right to receive the Merger consideration. Each share of Series B Cumulative Voting Preferred Stock of the Company will remain outstanding in accordance with its terms following the effective time of the Merger. New Accounting Pronouncements Description Date of adoption Effect on our consolidated financial statements or other significant matters Standards adopted: Financial instruments - credit impairment In June 2016, the FASB issued guidance amending the accounting for the credit impairment of certain financial instruments. Under the new guidance, credit losses are estimated using an expected loss model under which an allowance for credit losses is established and reflected as a charge to earnings. The allowance is based on the probability of loss over the life of the instrument, considering historical, current and forecast information. The new guidance differs significantly from the incurred loss model used historically, and results in the earlier recognition of credit losses. Since changes in the allowance are reflected in earnings, the new guidance may increase the volatility of earnings as the assumptions used in estimating the allowance are revised. Our available-for-sale fixed maturities will continue to apply the incurred loss model; however, such losses will also be in the form of an allowance for credit losses rather than an adjustment to the cost basis of the security. The new guidance permits entities to recognize improvements in credit loss estimates on fixed maturity available-for-sale securities by immediately reducing the allowance through earnings. January 1, 2020 Upon adoption using the modified retrospective approach, a cumulative effect adjustment of $2.7 million after offsets was recorded to retained earnings as of the first reporting period in which the new guidance was effective. The cumulative effect adjustment arose from the establishment of an allowance for credit losses on our mortgage loan investments totaling $3.1 million and reinsurance recoverable totaling $0.9 million, before offsets. Standards not yet adopted: Targeted improvements: long-duration contracts In August 2018, the FASB issued guidance that will change the accounting for long-duration insurance contracts. The new guidance impacts several facets of the accounting for such contracts including the accounting for future policy benefits associated with traditional non-participating and limited payment insurance contracts as well as for guaranteed minimum benefits and the amortization model used for deferred acquisition costs. Disclosures as well as presentation of financial results will also change under the new guidance. January 1, 2023 We are currently evaluating the impact of this guidance on our consolidated financial statements but expect the impact to the timing of profit emergence for the impacted insurance contracts to be significant. Adoption of certain portions of the guidance may be applied on a modified retrospective basis and others on a full retrospective basis. Reinsurance Recoverable The allowance for credit losses on our reinsurance recoverable is based on an estimate of credit losses that may occur over the life of the underlying ceded insurance business. We develop loss factors that are applied to the amounts due from each reinsurer, which considers the potential severity and likelihood of loss based on the relative risk profile of each reinsurer, our internal loss history and those of other organizations, along with economic forecasts. We also consider other sources of information regarding individual reinsurers, as applicable, including amounts past-due according to the terms of the reinsurance contracts. Reinsurance recoverable assets are reported in our consolidated balance sheets net of the allowance for credit losses. Amounts deemed to be uncollectible are written off against the allowance. Changes in the allowance are reported within the consolidated statement of operations as “Underwriting, acquisition and insurance expenses.” Allowance on Reinsurance Recoverables Three months ended March 31, 2021 (Dollars in thousands) Beginning balance of the allowance for credit losses $ 857 Change in allowance for credit losses (2) Ending balance of the allowance for credit losses $ 855 No reinsurance recoverables were considered past due as of March 31, 2021.

The amount of accrued interest excluded from the amortized cost basis of fixed maturities and included in accrued investment income on the balance sheet totaled $70.5 million at March 31, 2021. Any fixed maturity delinquent on contractual payments over 90 days past due is placed on non-accrual status. If the fixed maturity is placed on non-accrual status the prior accrued interest income is reversed through net investment income. Interest income received on non-performing fixed maturities is generally recognized on a cash basis. Once fixed maturities are classified as non-accrual, the resumption of the interest accrual would commence only after all past due interest has been collected. There was no interest reversed during the three months ended March 31, 2021 or March 31, 2020.

Fixed maturities in the above tables include 381 securities from 303 issuers at March 31, 2021 and 119 securities from 95 issuers at December 31, 2020. Unrealized losses increased during the three months ended March 31, 2021 primarily due to an increase in U.S. treasury rates. We do not consider securities declines in fair value below amortized cost to be due to a credit loss when the market decline is attributable to factors such as interest rate movements, market volatility, liquidity or spread widening when recovery of all amounts due under the contractual terms of the security is anticipated. Based on our intent not to sell and our belief that we will not be required to sell these securities before recovery of their amortized cost basis, we do not consider these investments to have a credit loss allowance, and they do not require a loss allowance established at March 31, 2021. The following summarizes the more significant unrealized losses on fixed maturity securities by investment category as of March 31, 2021. Corporate securities : The largest unrealized losses were in the utilities sector ($94.8 million fair value and $5.4 million unrealized loss) and in the energy sector ($42.1 million fair value and $3.3 million unrealized loss). The majority of losses is attributed to a general rise in treasury interest rates. The energy sector losses were attributable to credit spreads that remain wide which is associated with the decline in crude oil prices. Energy-related companies have been negatively impacted by the decline in oil prices due to a decrease in demand brought on by COVID-19. Residential mortgage-backed securities: The unrealized losses on residential mortgage-backed securities were primarily due to price declines on legacy and newer issue bonds. The legacy bonds are still at an unrealized gain overall, but some individual securities remain at an unrealized loss. The newer issue residential mortgage-backed securities are comprised of bonds issued during and after 2013 with strong underwriting and collateral characteristics. Primarily, losses were attributable to credit spread widening which led to lower prices on some securities. These securities tend to have higher credit scores with higher credit enhancement and lower loan-to-value ratios which position them favorably against default during economic disruptions such as those caused by COVID-19. Commercial mortgage-backed securities: The unrealized losses on commercial mortgage-backed securities were primarily due to spread widening. The wider spreads were caused by continued market uncertainty brought on by the COVID-19 virus for some securities. The contractual cash flows of these investments are based on mortgages backing the securities. Other asset-backed securities : The unrealized losses on asset-backed securities (ABS) were primarily due to concerns regarding COVID-19 and the resulting impact on consumer and commercial loans. Spreads are generally back to pre-COVID levels. The majority of our ABS have a sequential-pay structure that increases credit support as the pool amortizes. The average life of our ABS is 2.7 years, down from 5.4 years at purchase. Average credit support for the portfolio has increased from 9% at time of purchase to 18%. Our ABS portfolio is rated approximately 72% NAIC-1 . The unrealized losses on collateralized loan obligations (CLO) are due to concerns regarding COVID-19 and the resulting impact on leveraged loans. Our CLO portfolio is of high quality, with 100% rated NAIC-1. Internal stress testing has indicated that the weighted average constant default rate (CDR) of our portfolio without suffering a loss is 17%. The CDR is the constant default rate (annually) that a CLO must suffer before our tranche takes its first dollar loss. State, municipal and other governments: The unrealized losses on state, municipal and other government securities were primarily due to general spread widening relative to spreads at which we acquired the bonds, and uncertainty related to pandemic impacts on revenues in select sectors. Our allowance for credit losses at March 31, 2021 includes two financial sector bonds experiencing ongoing weakness in operating performance. The allowance for these bonds was established as the difference between the amortized cost and present value of expected cash flows, which is equal to fair value. Our allowance for credit losses also includes an asset backed security due to the difference between the amortized cost and the present value of the expected cash flows. We also continue to hold an allowance of $0.9 million on a promissory note held in other investments due to the possibility of not collecting the full balance of the note.

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 collateral to absorb losses should we be required to foreclose and take possession of the collateral. The amount of accrued interest excluded from the cost basis of the mortgage loans and included in accrued investment income on the balance sheet totaled $3.4 million at March 31, 2021. Any loan delinquent on contractual payments is considered non-performing. Mortgage loans are placed on non-accrual status if the loan is over 90 days past due. If the loan is placed on non-accrual status the prior accrued interest income is reversed through net investment income. Interest income received 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. At March 31, 2021 and December 31, 2020, there were no non-performing loans over 30 days past due on contractual payments. At March 31, 2021, we had committed to provide additional funding for mortgage loans totaling $21.6 million. These commitments arose in the normal course of business at terms that are comparable to similar investments.

Appraisals are updated periodically when there is indication of a possible significant collateral decline or there are loan modifications or refinance requests. Mortgage loans are rated internally to provide a current qualitative rating of each loan. We review the capital structure, collateral strength, physical occupancy, financial stability of the operating income stream, debt service coverage ratio, outstanding loan balance to estimated value of the collateral, property improvements and the financial strength of the borrower when determining the internal loan rating. Loans of high quality, low risk and with little concern of default or extension risk are rated an A; loans of moderate quality and moderate risk are rated a B; loans of low quality and high risk are rated a C, and loans for which there is concern of credit default are rated a W.

The loans are segmented by an internal risk rating as well as geographic region with an estimated loss ratio applied against each segment. For the years after our reasonable and supportable forecast period we graded the expected loss ratio over the estimated remaining recessionary period to our actual loss history. During the quarter ended March 31, 2021, our allowance did not change significantly from December 31, 2020 as the aggregate principal balance on our loans and other inputs into the model remained relatively stable. Amounts on mortgage loans deemed to be uncollectible are charged off and removed from the valuation allowance.

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 three months ended March 31, 2021 or March 31, 2020.

Realized gains and losses on sales of investments are determined based on specific identification. 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. After determining that we have a variable interest, we review our involvement in the VIE to determine whether we have both the power to direct activities that most significantly impact the economic performance of the VIE, and the obligation to absorb losses or the rights to receive benefits that could be potentially significant to the VIE. This analysis includes a review of the purpose and design of the VIE as well as the role that we played in the formation of the entity and how that role could impact our ability to control the VIE. We also review the activities and decisions considered significant to the economic performance of the VIE and assess what power we have in directing those activities and decisions. Finally, we review the agreements in place to determine if there are any guarantees that would affect our maximum exposure to loss. We have reviewed the circumstances surrounding our investments in VIEs, which consist of (i) limited partnerships or limited liability companies accounted for under the equity method included in securities and indebtedness of related parties and (ii) non-guaranteed federal low income housing tax credit (LIHTC) investments included in other assets. In addition, we have reviewed the ownership interests in our VIEs and determined that we do not hold direct majority ownership or have other contractual rights (such as kick out rights) that give us effective control over these entities resulting in us having both the power to direct activities that most significantly impact the economic performance of the VIE and the obligation to absorb losses or the right to receive benefits that could be potentially significant to the VIE. The maximum loss exposure relative to our VIEs is limited to the carrying value and any unfunded commitments that exist for each particular VIE. We also have not provided additional support or other guarantees that were not previously contractually required (financial or otherwise) to any of the VIEs as of March 31, 2021 or December 31, 2020. Based on this analysis, none of our VIEs were required to be consolidated at March 31, 2021 or December 31, 2020. LIHTC investments take the form of limited partnerships or limited liability companies, which in turn invest in a number of low income housing projects. We use the proportional amortization method of accounting for these investments. The proportional amortization method amortizes the cost of the investment over the period in which the investor expects to receive tax credits and other tax benefits, and the resulting amortization is recognized along with the tax benefit as a component of federal income tax expense on our consolidated statements of operations.

These structured securities include all of the residential mortgage-backed securities, commercial mortgage-backed securities and other asset-backed securities included in our fixed maturity securities. Our maximum exposure to loss on these securities is limited to our carrying value of the investment. We have determined that we are not the primary beneficiary of these structured securities because we do not have the power to direct the activities that most significantly impact the entities’ economic performance. Derivative Instruments Our primary derivative exposure relates to purchased call options, which provide an economic hedge against the embedded derivatives in our indexed products. We also have embedded derivatives within our modified coinsurance agreements as well as an interest-only fixed maturity investment. We do not apply hedge accounting to any of our derivative positions, and they are held at fair value.

We are exposed to credit losses on our call options in the event of nonperformance of the derivative counterparties. This credit risk is minimized by purchasing such agreements from financial institutions with high credit ratings (currently rated A or better by nationally recognized statistical rating organizations). We have also entered into credit support agreements with the counterparties requiring them to post collateral when net exposures exceed pre-determined thresholds that vary by counterparty. The net amount of such exposure is essentially the market value less collateral held for such agreements with each counterparty. The call options are supported by securities collateral received of $22.5 million at March 31, 2021, which is held in a separate custodial account. Subject to certain constraints, we are permitted to sell or re-pledge this collateral, but do not have legal rights to the collateral; accordingly, it has not been recorded on our balance sheet. We have elected to present our derivative receivables netted with the obligation to return cash collateral received on our balance sheet in other investments. We received cash collateral of $8.5 million included in cash and cash equivalents on our balance sheet as of March 31, 2021. At March 31, 2021, none of the collateral had been sold or re-pledged. As of March 31, 2021, our net derivative exposure recorded on the balance sheet without the off balance sheet collateral was $28.1 million.

Fair Values [Abstract]
Fair Value	Fair Values Fair value is based on an exit price, which is the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. 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, or, if 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. The following methods and assumptions were used in estimating the fair value of our financial instruments measured at fair value on a recurring basis: 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 political subdivisions 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, we 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 with no quoted market prices 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 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 for which an exit price based on relevant observable inputs is not obtained, the fair value is determined using a matrix calculation. Fair values estimated using 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 that 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 fluctuations based on our knowledge of the market and the particular instrument. As fluctuations are noted, we will perform further research that may include discussions with the original pricing source or other external sources to ensure we agree 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 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 non-redeemable preferred stock. Estimated fair value for the non-redeemable preferred stock is obtained from external pricing sources using a matrix pricing approach. Level 3 equity securities consist of non-redeemable preferred stock for which fair value estimates are based on the value of comparable securities that are actively traded. Increases in spreads 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 that 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. Other investments: Level 2 other investments measured at fair value 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 - indexed product embedded derivatives : Indexed product contracts include embedded derivatives that 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 that require management judgment include the risk margin as well as our credit risk. Should the risk margin increase or the credit risk decrease, the discounted cash flows and the estimated fair value of the obligation will increase. 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.

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, which is 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. The Company has other financial assets and financial liabilities that are not carried at fair value but for which fair value disclosure is required.

Segment Information

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. Our Corporate and Other segment consists of less significant business activities. Our chief operating decision makers use pre-tax adjusted operating income to evaluate segment performance and allocate resources. Pre-tax adjusted operating income consists of pre-tax net income adjusted to exclude realized gains and losses on investments including the change in fair value of equity securities, the change in allowances for credit losses on investments, and the change in fair value of derivatives as the impact of these items can fluctuate greatly from period to period. These fluctuations make it difficult to analyze core operating trends. In addition, for derivatives not designated as hedges, there is a mismatch between the valuation of the asset and liability when deriving net income. For example, certain call options relating to our indexed annuity business are one-year assets while the embedded derivatives in the indexed contracts represent the rights of the contract holder to receive index credits over the entire period the indexed products are expected to be in force. We also exclude from pre-tax adjusted operating income, expenses related to the proposed merger discussed in Note 1 to the consolidated financial statements, as these expenses are not incurred in the normal course of our operations. Adjustments to pre-tax net income are net of amortization of unearned revenue reserves and deferred acquisition costs, as well as changes in interest sensitive product reserves. While not applicable for the periods reported herein, in determining pre-tax adjusted operating income we will also remove the impact of settlements or judgments arising from lawsuits, net of any recoveries from third parties, the cumulative effect of changes in accounting principles and discontinued operations. Segment results are reported net of inter-segment transactions.

Interest expense is attributable to the Corporate and Other segment. Expenditures for long-lived assets were not significant during the periods presented above. Goodwill at March 31, 2021 and December 31, 2020 was allocated among the segments as follows: Annuity ($3.9 million) and Life Insurance ($6.1 million). Equity income related to securities and indebtedness of related parties is attributable to the Life Insurance and Corporate and Other segments. The following chart provides the related equity income by segment. Equity Income by Operating Segment Three months ended March 31, 2021 2020 (Dollars in thousands) Pre-tax equity income: Life Insurance $ 4,524 $ 375 Corporate and Other 261 (86) Total pre-tax equity income 4,785 289 Income taxes (1,005) (61) Equity income, net of related income taxes $ 3,780 $ 228 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. Premiums collected is a common life insurance industry measure of agent productivity. Net premiums collected totaled $153.0 million for the quarter ended March 31, 2021 and $154.0 million for the same period in 2020. 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.

Accounting Changes and Error Corrections [Abstract]
Basis of Accounting, Policy [Policy Text Block]	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 three months ended March 31, 2021 are not necessarily indicative of the results that may be expected for the year ending December 31, 2021, especially when considering the risks and uncertainties associated with the novel coronavirus ("COVID-19") and the impact it may have on our business, results of operations and financial condition. We encourage you to refer to the notes to our consolidated financial statements included in Item 8 of our Form 10-K for the year ended December 31, 2020 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. Our estimates and assumptions could change in the future as more information becomes known about the impact of COVID-19. Our results of operations and financial condition may also be impacted by evolving regulatory, legislative and accounting interpretations and guidance.
New Accounting Pronouncements, Policy [Policy Text Block]	New Accounting Pronouncements Description Date of adoption Effect on our consolidated financial statements or other significant matters Standards adopted: Financial instruments - credit impairment In June 2016, the FASB issued guidance amending the accounting for the credit impairment of certain financial instruments. Under the new guidance, credit losses are estimated using an expected loss model under which an allowance for credit losses is established and reflected as a charge to earnings. The allowance is based on the probability of loss over the life of the instrument, considering historical, current and forecast information. The new guidance differs significantly from the incurred loss model used historically, and results in the earlier recognition of credit losses. Since changes in the allowance are reflected in earnings, the new guidance may increase the volatility of earnings as the assumptions used in estimating the allowance are revised. Our available-for-sale fixed maturities will continue to apply the incurred loss model; however, such losses will also be in the form of an allowance for credit losses rather than an adjustment to the cost basis of the security. The new guidance permits entities to recognize improvements in credit loss estimates on fixed maturity available-for-sale securities by immediately reducing the allowance through earnings. January 1, 2020 Upon adoption using the modified retrospective approach, a cumulative effect adjustment of $2.7 million after offsets was recorded to retained earnings as of the first reporting period in which the new guidance was effective. The cumulative effect adjustment arose from the establishment of an allowance for credit losses on our mortgage loan investments totaling $3.1 million and reinsurance recoverable totaling $0.9 million, before offsets. Standards not yet adopted: Targeted improvements: long-duration contracts In August 2018, the FASB issued guidance that will change the accounting for long-duration insurance contracts. The new guidance impacts several facets of the accounting for such contracts including the accounting for future policy benefits associated with traditional non-participating and limited payment insurance contracts as well as for guaranteed minimum benefits and the amortization model used for deferred acquisition costs. Disclosures as well as presentation of financial results will also change under the new guidance. January 1, 2023 We are currently evaluating the impact of this guidance on our consolidated financial statements but expect the impact to the timing of profit emergence for the impacted insurance contracts to be significant. Adoption of certain portions of the guidance may be applied on a modified retrospective basis and others on a full retrospective basis.
Reinsurance Accounting Policy [Policy Text Block]	Reinsurance Recoverable The allowance for credit losses on our reinsurance recoverable is based on an estimate of credit losses that may occur over the life of the underlying ceded insurance business. We develop loss factors that are applied to the amounts due from each reinsurer, which considers the potential severity and likelihood of loss based on the relative risk profile of each reinsurer, our internal loss history and those of other organizations, along with economic forecasts. We also consider other sources of information regarding individual reinsurers, as applicable, including amounts past-due according to the terms of the reinsurance contracts. Reinsurance recoverable assets are reported in our consolidated balance sheets net of the allowance for credit losses. Amounts deemed to be uncollectible are written off against the allowance. Changes in the allowance are reported within the consolidated statement of operations as “Underwriting, acquisition and insurance expenses.” Allowance on Reinsurance Recoverables Three months ended March 31, 2021 (Dollars in thousands) Beginning balance of the allowance for credit losses $ 857 Change in allowance for credit losses (2) Ending balance of the allowance for credit losses $ 855 No reinsurance recoverables were considered past due as of March 31, 2021.

[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 unobservable inputs. 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, which is 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.
