	Basis of Presentation and Nature of Business
	Fidelity & Guaranty Life (formerly, Harbinger F&G, LLC (“HFG”)) (“FGL” and, collectively with its subsidiaries, the “Company”) is a subsidiary of Harbinger Group Inc. (“HGI”). HGI is a diversified holding company focused on obtaining controlling equity stakes in companies that operate across a diversified set of industries. FGL and HGI’s shares of common stock trade on the New York Stock Exchange (“NYSE”) under the symbols “FGL” and “HRG,” respectively. In January of 2014, HGI transferred HGI’s ownership interest in FGL common shares to FS Holdco, Ltd, which is a direct wholly-owned subsidiary of HGI. HGI indirectly held 47,000,000 shares of FGL's outstanding common stock, representing an 80.4% interest at March 31, 2014.
	FGL’s primary business is the sale of individual life insurance products and annuities through independent agents, managing general agents, and specialty brokerage firms and in selected institutional markets. FGL’s principal products are deferred annuities (including fixed indexed annuity (“FIA”) contracts), immediate annuities and life insurance products. FGL markets products through its wholly-owned insurance subsidiaries, Fidelity & Guaranty Life Insurance Company (“FGL Insurance”) and Fidelity & Guaranty Life Insurance Company of New York (“FGL NY Insurance”), which together are licensed in all fifty states and the District of Columbia.
	Dollar amounts in the accompanying footnotes are presented in millions, unless otherwise noted.
	On August 9, 2013, the Company distributed its ownership interests in its wholly-owned subsidiaries, HGI Real Estate, LLC, and FS Holdco Ltd, to HGI and HGI's subsidiaries. Beginning on August 9, 2013 with the distribution of FS Holdco Ltd, the Company’s financials reflected the 10% reinsurance agreement, whereby FGL cedes 10% of its in-force annuity block not already reinsured on a funds withheld basis to Front Street RE (Cayman) Ltd. (“FSRCI”), a subsidiary of FS Holdco Ltd. Accordingly, the three and six months ended March 31, 2013 include net earnings of $12.7 and $17.4, respectively from HGI Real Estate, LLC and FS Holdco operations.
	Basis of Presentation
	The accompanying unaudited Condensed Consolidated Financial Statements of the Company included herein have been prepared pursuant to the rules and regulations of the Securities and Exchange Commission (“SEC”). The financial statements reflect all adjustments that are, in the opinion of management, necessary for a fair statement of such information. All such adjustments are of a normal recurring nature. Although the Company believes that the disclosures are adequate to make the information presented not misleading, certain information and footnote disclosures, including a description of significant accounting policies normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”), have been condensed or omitted pursuant to such rules and regulations. These interim financial statements should be read in conjunction with the Company’s audited consolidated financial statements and notes thereto included in the Company’s Registration Statement on Form S-1/A filed with the SEC on December 3, 2013 (the “Form S-1”). The results of operations for the three and six months ended March 31, 2014 are not necessarily indicative of the results for any subsequent periods or the entire fiscal year ending September 30, 2014.
	The Company’s fiscal quarters end on the last calendar day of the months of December, March, June and September.

Significant Accounting Policies and Practices	'
	Significant Accounting Policies and Practices
	Principles of Consolidation
	The accompanying unaudited condensed consolidated financial statements include the accounts of FGL and all other entities in which FGL has a controlling financial interest (none of which are variable interest entities). All intercompany accounts and transactions have been eliminated in consolidation.
	Recent Accounting Pronouncements
	Offsetting Assets and Liabilities
	In December 2011, the Financial Accounting Standards Board (“FASB”) issued amended disclosure requirements for offsetting financial assets and financial liabilities to allow investors to better compare financial statements prepared under GAAP with financial statements prepared under International Financial Reporting Standards. The new standards are effective for the Company beginning in the first quarter of its fiscal year ending September 30, 2014. ASU 2011-11 Disclosures about Offsetting Assets and Liabilities - was adopted by the Company effective October 1, 2013. FGL does not offset any of its derivative transactions, including bifurcated embedded derivatives, in its statement of financial position. The Company only enters into purchased equity options and long futures contracts. The Company has not entered into any repurchase and reverse repurchase agreements or securities borrowing and lending transactions. Accordingly, no additional disclosures are required.
	Investments in Qualified Affordable Housing Projects
	In January 2014, the FASB issued amended guidance which allows investors in Low Income Housing Tax Credit (“LIHTC”) programs that meet specified conditions to present the net tax benefits (net of the amortization of the cost of the investment) within income tax expense. The cost of the investments that meet the specified conditions will be amortized in proportion to (and over the same period as) the total expected tax benefits, including the tax credits and other tax benefits, as they are realized on the tax return. The guidance is required to be applied retrospectively, if investors elect the proportional amortization method. However, if investors have existing LIHTC investments accounted for under the effective-yield method at adoption, they may continue to apply that method for those existing investments.  The new standards will become effective for the Company beginning in the first quarter of its fiscal year ending September 30, 2016.  The Company is currently evaluating the impact of this new accounting guidance on its consolidated financial position and results of operations.
	Income Taxes
	FGL and certain of its non-life insurance subsidiaries are included in the consolidated U.S. Federal income tax return of HGI. The Company’s life insurance subsidiaries file a consolidated life insurance income tax return. Income taxes are accounted for under the asset and liability method. Deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax basis and operating loss and tax credit carryforwards. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The Company assesses the recoverability of its deferred tax assets in each reporting period under the guidance outlined within ASC 740 (“Income Taxes”). The guidance requires an assessment of both positive and negative evidence in determining the realizability of deferred tax assets. A valuation allowance is required to reduce the Company’s deferred tax asset to an amount that is more likely than not to be realized. In determining the net deferred tax asset and valuation allowance, management is required to make judgments and estimates related to projections of future profitability.  These judgments include the following: the timing and extent of the utilization of net operating loss carry-forwards, the reversals of temporary differences, and tax planning strategies.  Because of the change in facts and circumstances described in Note 11 of the Financial Statements, the Company determined that it was now more likely than not that a portion of its existing deferred tax assets that had previously had a valuation allowance placed against them, were now more likely than not recoverable.  Therefore, the Company released a portion of its valuation allowance and recognized a $35.0 million gain in the current period income statement.  After the valuation allowance release, the Company still has a partial valuation allowance of $123.4 million against its gross deferred tax assets of $296.6 million as of March 31, 2014 for other deferred tax assets that are not likely to be realized.  The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date. The Company has the ability and intent to recover in a tax-free manner assets (or liabilities) with book/tax basis differences for which no deferred taxes have been provided, in accordance with ASC Topic 740, “Income Taxes”.
	The Company applies the accounting guidance for uncertain tax positions which prescribes a minimum recognition threshold a tax position is required to meet before being recognized in the financial statements. The guidance also provides information on derecognition, measurement, classification, interest and penalties, accounting in interim periods, disclosure and transition. The Company recognizes the effect of income tax positions only if those positions are more likely than not of being sustained. Recognized income tax positions are measured at the largest amount that is greater than 50% likely of being realized. Changes in recognition or measurement are reflected in the period in which the change in judgment occurs. Accrued interest expense and penalties related to uncertain tax positions are recorded in “Income tax benefit” in the Company’s Consolidated Statements of Operations. The Company had no unrecognized tax benefits related to uncertain tax positions as of March 31, 2014 and September 30, 2013.

Risks and Uncertainties [Abstract]	'
Significant Risks and Uncertainties	'
	Significant Risks and Uncertainties
	Use of Estimates
	The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Due to the inherent uncertainty involved in making estimates, actual results in future periods could differ from those estimates.
	The Company’s significant estimates which are susceptible to change in the near term relate to (1) recognition of deferred tax assets and related valuation allowances, (2) fair value of certain invested assets and derivatives including embedded derivatives (see Notes 4 and 5), (3) Other than temporary impairment “OTTI” of available-for-sale investments (see Note 4), (4) amortization of intangibles (see Note 7), (5) estimates of reserves for loss contingencies, including litigation and regulatory reserves (see Note 12) and (6) reserves for future policy benefits and product guarantees.
	Concentrations of Financial Instruments
	As of March 31, 2014 and September 30, 2013, the Company’s most significant investment in one industry, excluding U.S. Government securities, was its investment securities in the banking industry with a fair value of $2,019.4, or 11.3% and $1,892.1 or 11.7%, respectively, of the invested assets portfolio. The Company’s holdings in this industry include investments in 78 different issuers with the top ten investments accounting for 37.7% of the total holdings in this industry. As of March 31, 2014, the company had no investments that exceeded 10% of stockholders equity. As of September 30, 2013, the Company had investments in 6 issuers that exceeded 10% of stockholders equity with a fair value of $788.7, or 4.9% of the invested assets portfolio. Additionally, the Company’s largest concentration in any single issuer as of March 31, 2014 and September 30, 2013, had a fair value of $136.8 and $150.7 or 0.8% and 0.9% of the invested assets portfolio, respectively.
	Concentrations of Financial and Capital Markets Risk
	The Company is exposed to financial and capital markets risk, including changes in interest rates and credit spreads which can have an adverse effect on the Company’s results of operations, financial condition and liquidity. The Company expects to continue to face challenges and uncertainties that could adversely affect its results of operations and financial condition.
	The Company’s exposure to interest rate risk relates primarily to the market price and cash flow variability associated with changes in interest rates. A rise in interest rates, in the absence of other countervailing changes, will decrease the net unrealized gain position of the Company’s investment portfolio and, if long-term interest rates rise dramatically within a six to twelve month time period, certain of the Company’s products may be exposed to disintermediation risk. Disintermediation risk refers to the risk that policyholders may surrender their contracts in a rising interest rate environment, requiring the Company to liquidate assets in an unrealized loss position. This risk is mitigated to some extent by the high level of surrender charge protection provided by the Company’s products.
	Concentration of Reinsurance Risk
	The Company has a significant concentration of reinsurance with Wilton Reassurance Company (“Wilton Re”) and FSRCI (an affiliate) that could have a material impact on the Company’s financial position in the event that Wilton Re or FSRCI fail to perform their obligations under the various reinsurance treaties. As of March 31, 2014, the net amount recoverable from Wilton Re was $1,354.5 and the net amount recoverable from FSRCI is $1,306.5. The Company monitors both the financial condition of individual reinsurers and risk concentration arising from similar geographic regions, activities and economic characteristics of reinsurers to reduce the risk of default by such reinsurers.

	Included in AOCI were cumulative unrealized gains of $0.9 and unrealized losses of $1.9 related to the non-credit portion of OTTI on non-agency residential mortgage-backed securities ("RMBS") at March 31, 2014 and September 30, 2013. The non-agency RMBS unrealized gains and losses represent the difference between amortized cost and fair value on securities that were previously impaired. There have been no impairments or write downs on any of the 2014 purchased non-agency RMBS.
	Securities held on deposit with various state regulatory authorities had a fair value of $14,334.4 and $19.4 at March 31, 2014 and September 30, 2013, respectively. The increase in securities held on deposits is due to the FGL Insurance's re-domestication from Maryland to Iowa. Under Iowa regulations, insurance companies are required to hold securities on deposit in an amount no less than the company's legal reserve as prescribed by Iowa regulations.
	In accordance with the Company's Federal Home Loan Bank of Atlanta (“FHLB”) agreements, the investments supporting the funding agreement liabilities are pledged as collateral to secure the FHLB funding agreement liabilities. The collateral investments had a fair value of $592.3 and $604.9 at March 31, 2014 and September 30, 2013, respectively.
	The amortized cost and fair value of fixed maturity available-for-sale securities by contractual maturities, as applicable, are shown below. Actual maturities may differ from contractual maturities because issuers may have the right to call or pre-pay obligations.

	The Company's available-for-sale securities with unrealized losses are reviewed for potential OTTI. In evaluating whether a decline in value is other-than-temporary, the Company considers several factors including, but not limited to the following: (1) the extent and the duration of the decline; (2) the reasons for the decline in value (credit event, currency or interest-rate related, including general credit spread widening); and (3) the financial condition of and near-term prospects of the issuer. The Company also considers the ability and intent to hold the investment for a period of time to allow for a recovery of value.
	The Company analyzes its ability to recover the amortized cost by comparing the net present value of cash flows expected to be collected with the amortized cost of the security. For mortgage-backed and asset-backed securities, cash flow estimates consider the payment terms of the underlying assets backing a particular security, including interest rate and prepayment assumptions, based on data from widely accepted third-party data sources or internal estimates. In addition to interest rate and prepayment assumptions, cash flow estimates also include other assumptions regarding the underlying collateral including default rates and recoveries, which vary based on the asset type and geographic location, as well as the vintage year of the security. For structured securities, the payment priority within the tranche structure is also considered. For all other debt securities, cash flow estimates are driven by assumptions regarding probability of default and estimates regarding timing and amount of recoveries associated with a default. If the net present value is less than the amortized cost of the investment, an OTTI is recognized. FGL has concluded that the fair values of the securities presented in the table below were not OTTI as of March 31, 2014.

	Reinsurance Related Embedded Derivatives
	Effective December 31, 2012, FGL Insurance entered into a modified coinsurance arrangement with FSRCI, meaning that funds were withheld by FGL Insurance. This arrangement creates an obligation for FGL Insurance to pay FSRCI at a later date, which resulted in an embedded derivative. This embedded derivative is considered a total return swap with contractual returns that are attributable to the assets and liabilities associated with this reinsurance arrangement. The fair value of the total return swap is based on the change in fair value of the underlying assets held in the funds withheld portfolio. Investment results for the assets that support the coinsurance with funds withheld reinsurance arrangement, including gains and losses from sales, are passed directly to the reinsurer pursuant to contractual terms of the reinsurance arrangement. The reinsurance related embedded derivative is reported in “Other assets” on the Condensed Consolidated Balance Sheets and the related gains or losses are reported in “Net investment gains” on the Condensed Consolidated Statements of Operations.
	Credit Risk
	The Company is exposed to credit loss in the event of nonperformance by its counterparties on the call options and reflects assumptions regarding this nonperformance risk in the fair value of the call options. The nonperformance risk is the net counterparty exposure based on the fair value of the open contracts less collateral held. The Company maintains a policy of requiring all derivative contracts to be governed by an International Swaps and Derivatives Association (“ISDA”) Master Agreement.
	Information regarding the Company’s exposure to credit loss on the call options it holds is presented in the following table:

	(a) Credit rating as of March 31, 2014.
	Collateral Agreements
	The Company is required to maintain minimum ratings as a matter of routine practice as part of its over-the-counter derivative agreements on ISDA forms. Under some ISDA agreements, the Company has agreed to maintain certain financial strength ratings. A downgrade below these levels provides the counterparty under the agreement the right to terminate the open derivative contracts between the parties, at which time any amounts payable by the Company or the counterparty would be dependent on the market value of the underlying derivative contracts. The Company’s current rating allows multiple counterparties the right to terminate ISDA agreements. No ISDA agreements have been terminated, although the counterparties have reserved the right to terminate the ISDA agreements at any time. In certain transactions, the Company and the counterparty have entered into a collateral support agreement requiring either party to post collateral when the net exposures exceed pre-determined thresholds. These thresholds vary by counterparty and credit rating. As of March 31, 2014 and September 30, 2013, counterparties posted $150.0 and $72.0 of collateral of which $108.9 and $72.0 is included in "Cash and cash equivalents" with an associated payable for this collateral included in "Other liabilities" on the Condensed Consolidated Balance Sheets. The remaining, $41.1 of non-cash collateral was held by a third-party custodian at March 31, 2014. Accordingly, the maximum amount of loss due to credit risk that the Company would incur if parties to the call options failed completely to perform according to the terms of the contracts was $121.5 and $149.8 at March 31, 2014 and September 30, 2013, respectively.
	The Company held 1,990 and 1,693 futures contracts at March 31, 2014 and September 30, 2013, respectively. The fair value of the futures contracts represents the cumulative unsettled variation margin (open trade equity, net of cash settlements). The Company provides cash collateral to the counterparties for the initial and variation margin on the futures contracts which is included in "Cash and cash equivalents" in the accompanying Condensed Consolidated Balance Sheets. The amount of collateral held by the counterparties for such contracts was $8.6 and $5.9 at March 31, 2014 and September 30, 2013, respectively.

Fair Value Disclosures [Abstract]	'
Fair Value of Financial Instruments	'
	Fair Value of Financial Instruments
	The Company’s measurement of fair value is based on assumptions used by market participants in pricing the asset or liability, which may include inherent risk, restrictions on the sale or use of an asset or non-performance risk, which may include the Company’s own credit risk. The Company’s estimate of an exchange price is the price in an orderly transaction between market participants to sell the asset or transfer the liability (“exit price”) in the principal market, or the most advantageous market in the absence of a principal market, for that asset or liability, as opposed to the price that would be paid to acquire the asset or receive a liability (“entry price”). The Company categorizes financial instruments carried at fair value into a three-level fair value hierarchy, based on the priority of inputs to the respective valuation technique. The three-level hierarchy for fair value measurement is defined as follows:
	Level 1 -Values are unadjusted quoted prices for identical assets and liabilities in active markets accessible at the measurement date.
	Level 2 -Inputs include quoted prices for similar assets or liabilities in active markets, quoted prices from those willing to trade in markets that are not active, or other inputs that are observable or can be corroborated by market data for the term of the instrument. Such inputs include market interest rates and volatilities, spreads and yield curves.
	Level 3 - Certain inputs are unobservable (supported by little or no market activity) and significant to the fair value measurement. Unobservable inputs reflect the Company’s best estimate of what hypothetical market participants would use to determine a transaction price for the asset or liability at the reporting date based on the best information available in the circumstances.
	In certain cases, the inputs used to measure fair value may fall into different levels of the fair value hierarchy. In such cases, an investment’s level within the fair value hierarchy is based on the lower level of input that is significant to the fair value measurement. The Company’s assessment of the significance of a particular input to the fair value measurement in its entirety requires judgment and considers factors specific to the investment.
	When a determination is made to classify an asset or liability within Level 3 of the fair value hierarchy, the determination is based upon the significance of the unobservable inputs to the overall fair value measurement. Because certain securities trade in less liquid or illiquid markets with limited or no pricing information, the determination of fair value for these securities is inherently more difficult. However, Level 3 fair value investments may include, in addition to the unobservable or Level 3 inputs, observable components, which are components that are actively quoted or can be validated to market-based sources.
	The carrying amounts and estimated fair values of the Company’s financial instruments for which the disclosure of fair values is required, including financial assets and liabilities measured and carried at fair value on a recurring basis, with the exception of investment contracts, a portion of related party loans, portions of other invested assets and debt, are summarized according to the hierarchy previously described, as follows:

	Valuation Methodologies
Fixed Maturity Securities & Equity Securities
The Company measures the fair value of its securities based on assumptions used by market participants in pricing the security. The most appropriate valuation methodology is selected based on the specific characteristics of the fixed maturity or equity security, and the Company will then consistently apply the valuation methodology to measure the security’s fair value. The Company's fair value measurement is based on a market approach, which utilizes prices and other relevant information generated by market transactions involving identical or comparable securities. Sources of inputs to the market approach include a third-party pricing service, independent broker quotations or pricing matrices. The Company uses observable and unobservable inputs in its valuation methodologies. Observable inputs include benchmark yields, reported trades, broker-dealer quotes, issuer spreads, two-sided markets, benchmark securities, bids, offers and reference data. In addition, market indicators and industry and economic events are monitored and further market data will be acquired when certain thresholds are met. For certain security types, additional inputs may be used, or some of the inputs described above may not be applicable. For broker-quoted only securities, quotes from market makers or broker-dealers are obtained from sources recognized to be market participants. Management believes the broker quotes are prices at which trades could be executed based on historical trades executed at broker-quoted or slightly higher prices.
The Company did not adjust prices received from third parties as of March 31, 2014 and September 30, 2013. However, the Company does analyze the third-party valuation methodologies and its related inputs to perform assessments to determine the appropriate level within the fair value hierarchy.
Derivative Financial Instruments
The fair value of derivative assets and liabilities is based upon valuation pricing models, which represents what the Company would expect to receive or pay at the balance sheet date if it canceled the options, entered into offsetting positions, or exercised the options. The fair value of futures contracts represents the cumulative unsettled variation margin (open trade equity, net of cash settlements). Fair values for these instruments are determined externally by an independent actuarial firm using market-observable inputs, including interest rates, yield curve volatilities, and other factors. Credit risk related to the counterparty is considered when estimating the fair values of these derivatives. The fair values of the embedded derivatives in the Company’s FIA products are derived using market indices, pricing assumptions and historical data. The fair value of the reinsurance related embedded derivative in the funds withheld reinsurance agreement with FSRCI is estimated based upon the change in the fair value of the assets supporting the funds withheld from reinsurance liabilities. As the fair value of the assets is based on a quoted market price (Level 2), the fair value of the embedded derivative is based on market-observable inputs and is classified as Level 2.
Investment contracts include deferred annuities, FIAs, indexed universal life policies (“IULs”) and immediate annuities. The fair value of deferred annuity, FIA, and IUL contracts is based on their cash surrender value (i.e. the cost the Company would incur to extinguish the liability) as these contracts are generally issued without an annuitization date. The fair value of immediate annuities contracts is derived by calculating a new fair value interest rate using the updated yield curve and treasury spreads as of the respective reporting date. At March 31, 2014 and September 30, 2013, this resulted in lower fair value reserves relative to the carrying value. The Company is not required to, and has not, estimated the fair value of the liabilities under contracts that involve significant mortality or morbidity risks, as these liabilities fall within the definition of insurance contracts that are exceptions from financial instruments that require disclosures of fair value.
Other Invested Assets
Fair value of our loan participation interest securities has been assessed to be equal to the unpaid principal balance of the participation interest as of March 31, 2014. In making this assessment the Company considered the sufficiency of the underlying loan collateral, movements in the benchmark interest rate between origination date and March 31, 2014, the primary market participant for these securities and the short-term maturity of these loans (less than 1 year).
All of the other financial instruments included in other investments, primarily commercial mortgage loans ("CMLs") and policy loans, are carried at amortized cost which approximates fair value. Information on determining the carry value of these investments is described below:
In September 2013, the Company initiated a commercial loan program with Principal Real Estate Investors ("Principal"). The Company has funded eight CMLs originated and serviced by Principal with a fair value of $116.5 at March 31, 2014 which is equal to amortized cost as these loans were recently originated and are performing in good standing with no material credit concerns with the borrower or the property. Principal monitors the status of the payment obligations, the credit quality of the borrower and the property as well as for other events that may impact the performance and principal repayment of the CMLs. Additionally, the Company reviews Principal's valuation methodologies and processes to perform assessments. A CMLs' good standing and payment obligations are material factors in evaluating CMLs carrying value. At March 31, 2014, all eight CMLs are performing in good standing and there are no credit or other events which would require impairment evaluation.
Also included in other invested assets are policy loans. We have not attempted to determine the fair values associated with our policy loans, as we believe any differences between carrying value and the fair values afforded these instruments are immaterial to our consolidated financial position and, accordingly, the cost to provide such disclosure does not justify the benefit to be derived.
Related Party Loans & Related Party Investments
The related party loans (discussed in Note 14) carrying value at par approximates fair value, as this is the exit price for the obligation of these loans.
Quantitative information regarding significant unobservable inputs used for recurring Level 3 fair value measurements of financial instruments carried at fair value as of March 31, 2014 and September 30, 2013 are as follows:

The significant unobservable inputs used in the fair value measurement of FIA embedded derivatives included in contractholder funds are market value of option, interest swap rates, mortality multiplier, surrender rates, and non-performance spread. The mortality multiplier at March 31, 2014 and September 30, 2013, is based on the 2000 annuity tables and assumes the contractholder population is 50% female and 50% male. Significant increases (decreases) in the market value of option in isolation would result in a higher or lower, respectively, fair value measurement. Significant increases or decreases in interest swap rates, mortality multiplier, surrender rates, or non-performance spread in isolation would result in a lower or higher, respectively, fair value measurement. Generally, a change in any one unobservable input would not result in a change in any other unobservable input.
Changes in unrealized losses (gains), net in the Company’s FIA embedded derivatives are included in "Benefits and other changes in policy reserves" in the Condensed Consolidated Statements of Operations.
The following tables summarize changes to the Company’s financial instruments carried at fair value and classified within Level 3 of the fair value hierarchy for the three and six months ended March 31, 2014 and March 31, 2013 respectively. This summary excludes any impact of amortization of VOBA and DAC. The gains and losses below may include changes in fair value due in part to observable inputs that are a component of the valuation methodology.

(a)	The net transfers in and out of Level 3 during the six months ended March 31, 2013 were exclusively to or from Level 2.
The Company reviews the fair value hierarchy classifications each reporting period. Changes in the observability of the valuation attributes may result in a reclassification of certain financial assets or liabilities. Such reclassifications are reported as transfers in and out of Level 3, or between other levels, at the beginning fair value for the reporting period in which the changes occur. There were no transfers between Level 1 and Level 2 for the three or six months ended March 31, 2014. We transferred $79.3 U.S. Government securities from Level 1 into Level 2 for the three and six months ended March 31, 2013 reflecting the level of market activity in these instruments.
Primary market issuance and secondary market activity for certain asset-backed, hybrid and corporate securities during the three months and six months ended March 31, 2014 and March 31, 2013 increased the market observable inputs used to establish fair values for similar securities. These factors, along with more consistent pricing from third-party sources, resulted in the Company concluding that there is sufficient trading activity in similar instruments to support classifying these securities as Level 2 as of March 31. 2014 and March 31, 2013. Accordingly, the Company’s assessment resulted in net transfers out of Level 3 of $208.7 related to asset backed securities during the three and six months ended March 31, 2014 and of $38.9 and $52.9 related to corporate and hybrid securities during the three and six months ended March 31, 2013, respectively.
The following tables present the gross components of purchases, sales, and settlements, net, of Level 3 financial instruments for the three and six months ended March 31, 2014 and March 31, 2013, respectively. There were no issuances during these periods.

	Amortization of VOBA and DAC is based on the amount of gross margins or profits recognized, including investment gains and losses. The adjustment for unrealized net investment gains represents the amount of VOBA and DAC that would have been amortized if such unrealized gains and losses had been recognized. This is referred to as the “shadow adjustments” as the additional amortization is reflected in AOCI rather than the statement of operations. As of March 31, 2014 and September 30, 2013, the VOBA balance included cumulative adjustments for net unrealized investment gains/losses of $144.5 and $81.4 respectively, and the DAC balances included cumulative adjustments for net unrealized investment gains/losses of $23.5 and $18.6, respectively.
	The above DAC balances include $29.5 and $26.2 of deferred sales inducements, net of shadow adjustments, as of March 31, 2014 and September 30, 2013, respectively.
	The weighted average amortization period for VOBA is approximately 5.0 years. Estimated amortization expense for VOBA in future fiscal periods is as follows:

	On November 26, 2013, the Company’s board of directors increased the number of authorized shares of the Company’s common stock, par value $0.01 per share, from 100 thousand to 500,000 thousand and approved a stock split of the issued and outstanding shares of common stock at a ratio of 4,700-for-1, resulting in 47,000 thousand shares outstanding. Net income per common share and the weighted average common shares used in computing net income per share for the three and six months ended March 31, 2014 and 2013, included in the Company’s Consolidated Statement of Operations, have been adjusted to give effect to the stock split. Likewise, the amount of shares authorized, issued, and outstanding disclosed in the Company’s Consolidated Balance sheets have also been adjusted.
	In December 2013 the Company issued 9,750 thousand shares of common stock as well as 58 thousand unrestricted shares to its directors in connection with its initial public offering ("IPO") and began trading on the New York Stock Exchange under the ticker symbol "FGL." FGL also granted the underwriters an option to purchase an additional 1,463 thousand shares of common stock that was subsequently exercised. Subsequent to the offering HGI indirectly held 47,000 thousand shares of FGL's outstanding common stock, representing an 80.4% interest at March 31, 2014.
	On December 18, 2013, the Company received net proceeds from the IPO of $172.5. A portion of the proceeds were used to pay a special dividend of $43.0 to HGI.
	On March 3, 2014, FGL’s Board of Directors declared a quarterly cash dividend of $0.065 per share. The dividend was paid on March 31, 2014 to shareholders of record as of the close of business on March 17, 2014. The total cash payment of $3.9 (based on fully vested, outstanding shares of 58,271 thousand) was funded from the IPO proceeds.

	Stock Compensation
	In conjunction with the IPO, on November 7, 2013, FGL’s Board of Directors adopted a long term stock-based incentive plan (the “FGL 2013 Stock Incentive Plan” or the “Omnibus Plan”) under which certain officers, employees, directors and consultants are eligible to receive equity based awards. The Omnibus Plan was approved by the stockholder on November 19, 2013, became effective on December 12, 2013 and expires in December 2023. FGL’s Compensation Committee approved the granting of awards under the Omnibus Plan to certain employees, officers and directors (other than the members of the Compensation Committee). In addition, FGL’s Board of Directors approved the granting of awards to members of FGL’s Compensation Committee (the “Compensation Committee Awards”). The Compensation Committee Awards were not made under the Omnibus Plan; however, these awards will be construed and administered as if subject to the terms of the Omnibus Plan. FGL’s Board of Directors and stockholder also approved the granting of unrestricted common shares to its directors in lieu of cash compensation at the election of each individual director (the “Unrestricted Share Awards”). The Omnibus Plan, Compensation Committee Awards and the Unrestricted Share Awards are collectively referred to as the “FGL Plans” and are accounted for as equity plans. New shares are issued to satisfy stock option exercises. As of the date the stock awards are approved and communicated to the recipient, the fair value of stock options is determined using a Black-Scholes options valuation methodology, and the fair value of other stock awards is based upon the market value of the stock. The fair value of the awards is expensed over the service period, which generally corresponds to the vesting period, and is recognized as an increase to Additional paid-in capital in stockholders’ equity.
	Prior to the initial public offering, FGL did not offer stock-based compensation plans to any of its directors, employees or the directors or employees of its subsidiaries.
	FGL’s principal subsidiary, FGLH, sponsors stock-based incentive plans and dividend equivalent plans (“DEPs”) for its employees (the “FGLH Plans”). Awards under the FGLH Plans are based on the common stock of FGLH. In 2013, FGLH determined that all equity awards will be settled in cash when exercised and therefore are classified as liability plans. For these awards, the settlement value is classified as a liability, in "Other liabilities", on the Consolidated Balance Sheets and the liability is adjusted to the current fair value through net income at the end of each reporting period, which causes volatility in net income (loss) as a result of changes in the fair value of FGLH’s stock. The fair value of stock options is determined using a Black-Scholes options valuation methodology and the fair value of restricted stock units is based upon the fair value of FGLH’s stock. In connection with the IPO, the FGLH plans were frozen and no new awards will be granted under these plans. Outstanding awards will be permitted to vest in accordance with the award agreements and will be cash settled upon vesting or exercise.
	The Company recognized total stock compensation expense related to the FGL Plans and FGLH Plans as follows:

	FGL Plans
	FGL’s Compensation Committee is authorized to grant up to 2,838 thousand equity awards under the FGL Plans. On December 12, 2013, FGL granted 239 thousand stock options to certain officers, directors and other key employees under the Omnibus Plan and 10 thousand stock options to Compensation Committee members. These stock options vest in equal installments over a period of three years and expire on the seventh anniversary of the grant date. The total fair value of the option grants to certain officers and directors on the grant date was $0.6 and the total fair value of the option grants to other key employees on the grant date was $0.3. At March 31, 2014, the intrinsic value of stock options outstanding, exercisable and vested or expected to vest was $1.6, $0 and $1.6, respectively. During both the six months ended March 31, 2014 and 2013 the intrinsic value of stock options exercised was $0.
	A summary of FGL’s outstanding stock options as of March 31, 2014, and related activity during the three month period, is as follows (share amount in thousands):
	Stock Option Awards		Options		Weighted Average			Weighted Average Grant
					Exercise Price			Date Fair Value

	Exercisable at March 31, 2014		—
	Vested or expected to vest at March 31, 2014		242		17			3.71
	The following assumptions were used in the determination of these grant date fair values using the Black-Scholes option pricing model and based on the value of FGL's common stock:
		2014
	Risk-free interest rate	1.40%
	Assumed dividend yield	1.50%
	Expected option term	4.5 years
	Volatility	25%
	The dividend yield is based on the expected dividend rate during the expected life of the option. Expected volatility is based on the implied volatility of exchange-traded securities for life insurance companies. The risk-free interest rate is based on the U.S. Treasury yield curve in effect at the time of the grant. The expected life of the options granted represents the weighted-average period of time from the grant date to the date of exercise, expiration or cancellation based upon a simplified method.
	On December 12, 2013, FGL also granted 96 thousand restricted shares to certain officers and directors under the Omnibus Plan and 11 thousand restricted shares to Compensation Committee members. In addition, FGL granted 64 thousand restricted shares to other key employees on December 12, 2013; however, these awards were not communicated to the recipients until January 30, 2014 which was determined to be the grant date for accounting purposes. These shares vest in equal installments over a period of three years and expire on the seventh anniversary of the grant date. The total fair value of the restricted shares granted to certain officers and directors on their grant date was $1.8 and the total fair value of the restricted shares granted to other key employees on the grant date was $1.2.
	The restricted shares are entitled to any cash dividends paid on FGL’s stock prior to vesting of the restricted shares. The cash dividends are held by FGL until the shares become vested and are paid to the recipient at that time or are forfeited if the restricted shares do not vest.
	A summary of FGL’s restricted shares outstanding as of March 31, 2014, and related activity during the six months then ended, are as follows (share amount in thousands):

On December 12, 2013, FGL also granted 469 thousand performance restricted stock units (“PRSUs”) to senior executive officers under the Omnibus Plan. In addition, FGL granted 72 thousand PRSUs to a new senior executive officer on January 22, 2014. The award was communicated to and accepted by the senior executive officer on January 27, 2014. These units vest on September 30, 2016, contingent on the satisfaction of performance criteria and on the officer's continued employment unless otherwise noted in the agreement. The total fair value of the PRSUs on the grant date of December 12, 2013 was $8.0 and the total fair value of the PRSUs awarded to the senior executive officer on the grant date of January 27, 2014 was $1.4.
PRSUs subject to vesting are adjusted based on yearly performance, which is evaluated on two non-GAAP measures: (1) adjusted operating income, and (2) return on equity.

	Income Taxes
	The provision for income taxes represents federal income taxes. The effective tax rate for the three and six month period ended March 31, 2014 was 283.7% and (31.8)%, respectively. The effective tax rate for the three and six month period ended March 31, 2013 was 33.5% and 33.0%. The effective tax rate on pre-tax income differs from the U.S Federal statutory rate primarily due to current period changes to the Company’s valuation allowance offsetting its deferred tax asset position. The Company recognized a partial valuation allowance release of $35.0 million for the three and six month periods due to the adoption of a prudent and feasible tax planning strategy that makes it more likely than not that a portion of its capital loss carry forward deferred tax assets will now be realized.
	In assessing the recoverability of its deferred tax assets, management regularly considers the guidance outlined within ASC 740 (“Income Taxes”). The guidance requires an assessment of both positive and negative evidence in determining the realizability of deferred tax assets. A valuation allowance is required to reduce the Company’s deferred tax asset to an amount that is more likely than not to be realized. In determining the net deferred tax asset and valuation allowance, management is required to make judgments and estimates related to projections of future profitability. These judgments include the following: the timing and extent of the utilization of net operating loss carry-forwards, the reversals of temporary differences, and tax planning strategies.
	The Company maintains a valuation allowance against certain U.S. Internal Revenue Code, Section 382 ("Section 382") limited capital loss carry forwards and the deferred tax assets of its non-life insurance company subsidiaries. A valuation allowance has been placed against Section 382 limited capital loss carry forwards to reduce these deferred tax assets to an amount that is more-likely than not to be realized before the attributes expire. The non-life insurance company subsidiaries have a history of losses and insufficient sources of future income in order to recognize any portion of their deferred tax assets. The valuation allowance is reviewed quarterly and will be maintained until there is sufficient positive evidence to support a release. At each reporting date, management considers new evidence, both positive and negative, that could impact the future realization of deferred tax assets. Management will consider a release of the valuation allowance once there is sufficient positive evidence that it is more likely than not that the deferred tax assets will be realized. Any release of the valuation allowance will be recorded as a tax benefit increasing net income or other comprehensive income.
	During the current reporting quarter, market conditions changed sufficiently that Management determined it was prudent and feasible to adopt a new tax planning strategy. The strategy involves repositioning a portion of the investment portfolio to trigger $100.0 million in net unrealized built-in gain (“NUBIG”) securities. The sale of these assets will result in an increase to the Company’s Section 382 limit (i.e. the “adjusted limit”), enabling the Company to utilize capital loss carry forwards that will offset NUBIG-related gains. This strategy makes it more likely than not that the amount of capital loss carryforwards needed to offset those gains will be utilized. Therefore, a partial release of the valuation allowance offsetting the deferred tax asset related to capital loss carry forwards was recorded at the March 31, 2014 reporting date. Management intends to execute the transactions prior to the expiration of Section 382-limited capital loss carry forwards. The Company currently has capital loss carry forwards of $52.3 million that expire December 31, 2014 and $277.5 million that are set to expire December 31, 2015.
	Key considerations in the Company’s decision supporting adoption of the planning strategy include wider spreads in specific credit markets, increased range of executable reinvestment opportunities, and an enhanced focus on managing and increasing the Company’s Statutory Interest Maintenance Reserve (“IMR”) balance and capital position providing increased flexibility in volatile interest rate and credit spread markets.
	The Company has recorded a partial valuation allowance of $123.4 million against its gross deferred tax assets of $296.6 million as of March 31, 2014. The March 31, 2014 valuation allowance is an offset to capital loss carryforwards (post tax planning strategy execution) expected to expire, as well as non-life company deferred tax assets that will more likely than not be recovered due to lack of forecasted taxable income in the non-life segment.
	The Company’s tax provision changes quarterly based on recurring and non-recurring factors, including but not limited to, enacted tax legislation, tax audit settlements and changes in judgment from the evaluation of new information resulting in the recognition or de-recognition and/or re-measurement of a tax position taken in a prior period. Changes in judgment related to a tax position are generally recognized in the quarter in which any such change occurs.

	Regulatory and Litigation Matters
	FGL is assessed amounts by the state guaranty funds to cover losses to policyholders of insolvent or rehabilitated insurance companies. Those mandatory assessments may be partially recovered through a reduction in future premium taxes in certain states. At March 31, 2014, FGL has accrued $4.8 for guaranty fund assessments which is expected to be offset by estimated future premium tax deductions of $4.6.
	The Company has received inquiries from a number of state regulatory authorities regarding its use of the U.S. Social Security Administration’s Death Master File (the "Death Master File") and compliance with state claims practices regulation. To date, the Company has received inquiries from authorities in Maryland, Minnesota and New York. The New York Insurance Department issued a letter and subsequent regulation requiring life insurers doing business in New York to use the Death Master File or similar databases to determine if benefits were payable under life insurance policies, annuities, and retained asset accounts. Legislation requiring insurance companies to use the Death Master File to identify potential claims has recently been enacted in Maryland and other states. As a result of these legislative and regulatory developments, in May 2012, the Company undertook an initiative to use the Death Master File and other publicly available databases to identify persons potentially entitled to benefits under life insurance policies, annuities and retained asset accounts. During fiscal 2012, the Company incurred an $11.0 benefit expense, net of reinsurance, to increase reserves to cover potential benefits payable resulting from this ongoing effort. Based on its analysis to date, and management’s estimate, the Company believes the remaining accrual will cover the reasonably estimated liability arising out of these developments. In addition, the Company has received audit and examination notices from several state agencies responsible for escheatment and unclaimed property regulation in those states.  The Company has established a contingency of $2.0, the mid-point of an estimated range of $1.0 to $3.0, related to the external legal costs and administrative costs of said audits and examinations. Additional costs that cannot be reasonably estimated as of the date of this filing are possible as a result of ongoing regulatory developments and other future requirements related to this matter.
	The Company is involved in various pending or threatened legal proceedings, including purported class actions, arising in the ordinary course of business. In some instances, these proceedings include claims for unspecified or substantial punitive damages and similar types of relief in addition to amounts for alleged contractual liability or requests for equitable relief. In the opinion of management and in light of existing insurance and other potential indemnification, reinsurance and established reserves, such litigation is not expected to have a material adverse effect on the Company’s financial position, although it is possible that the results of operations and cash flows could be materially affected by an unfavorable outcome in any one period.
	On July 18, 2011, a putative class action Complaint was filed in the United States District Court for the Central District of California, captioned Eddie L. Cressy v. OM Financial Life Insurance Company, et. al., Case No. 2:2011-cv-05871. The Plaintiff asked the Court to certify the action as a class action on behalf of both a nationwide and a California class defined as certain persons who were sold OM Financial Life Insurance equity-indexed universal life insurance policies.
	The Plaintiff alleged, inter alia, that the Plaintiff and members of the putative class relied on defendants’ advice to purchase unsuitable insurance policies. After extensive motion practice, the federal court dismissed the federal causes of action, with prejudice, and, on May 9, 2013, declined to exercise supplemental jurisdiction over the state law claims, dismissed the state law claims, without prejudice, and granted the Plaintiff leave to re-file the state law claims in California state court.
	On July 5, 2013, the Plaintiff filed a putative class action captioned Eddie L. Cressy v. Fidelity Guaranty [sic] Life Insurance Company, et. al. in the Superior Court of California, County of Los Angeles, at No. BC-514340. The state court Complaint asserts, inter alia, that the Plaintiff and members of the putative class relied on Defendants’ advice in purchasing unsuitable equity-indexed insurance policies. The Plaintiff seeks to certify a class defined as “all persons who reside or are located in the state of California who were sold OM Financial/FGL Insurance equity-indexed universal life insurance policies as an investment.”
	On April 4, 2014, the Plaintiff, FGL Insurance and the other two defendants signed a Settlement Agreement, pursuant to which FGL Insurance has agreed to pay a total of $5.3 to settle the claims of a nationwide class consisting, with certain exclusions, of all persons who own or owned an OM Financial/FGL Insurance indexed universal life insurance policy issued from January 1, 2007 through March 31, 2014, inclusive.  As part of the settlement, FGL Insurance agreed to certification of the nationwide class for settlement purposes only. An amended Settlement Agreement was filed with the Court on April 23, 2014 as part of the Plaintiff’s Unopposed Motion for Preliminary Approval of Settlement and Conditional Class Certification, which is scheduled to be heard by the Court on May 21, 2014. FGL Insurance has the right to unilaterally terminate the settlement if either: (i) 100 policyholders or (ii) policyholders representing more than one percent (1%) of the total premiums paid opt out of or object to the settlement. The settlement is subject to other conditions and the Court’s final approval.
	At March 31, 2014, the Company estimated the total cost for the settlement, legal fees and other costs related to this class action would be $9.2 and established a liability for the unpaid portion of the estimate of $7.1. Based on the information currently available the Company does not expect the actual cost for settlement, legal fees and other related cost to differ materially from the amount accrued. The Company is seeking indemnification from OM Group (UK) Limited (“OMGUK”) under the First Amended and Restated Stock Purchase Agreement, dated February 17, 2011 (the “F&G Stock Purchase Agreement”) between HFG and OMGUK related to the settlement and the costs and fees in defending the Cressy litigation in both the federal and state courts. The Company has established an amount recoverable from OMGUK for the amount of $4.5, the collection of which the Company believes is probable. The actual amount recovered from OMGUK could be greater or less than the Company’s estimate, but the Company anticipates that the amount recovered will not be materially different than its current estimate. The settlement, legal fees and other costs related to this class action and the amount recoverable from OMGUK is presented net in the income statement in the caption “Benefits and other changes in policy reserves.”
	In light of the inherent uncertainties involved in the matter described above and uncertainties in litigation generally, there can be no assurance that this litigation, or any other pending or future litigation, will not have a material adverse effect on our business, financial condition, or results of operations.
	Guarantees
	The F&G Stock Purchase Agreement between HFG and OMGUK includes a Guarantee and Pledge Agreement which creates certain obligations for FGLH as a grantor and also grants a security interest to OMGUK of FGLH’s equity interest in FGL Insurance in the event that HFG fails to perform in accordance with the terms of the F&G Stock Purchase Agreement. The Company is not aware of any events or transactions that resulted in non-compliance with the Guarantee and Pledge Agreement.

Reinsurance	'
	Reinsurance
	The Company reinsures portions of its policy risks with other insurance companies. The use of reinsurance does not discharge an insurer from liability on the insurance ceded. The insurer is required to pay in full the amount of its insurance liability regardless of whether it is entitled to or able to receive payment from the reinsurer. The portion of risks exceeding the Company's retention limit is reinsured with other insurers. The Company seeks reinsurance coverage in order to limit its exposure to mortality losses and enhance capital management. The Company follows reinsurance accounting when there is adequate risk transfer. Otherwise, the deposit method of accounting is followed. The Company also assumes policy risks from other insurance companies.
	The effect of reinsurance on premiums earned, benefits incurred and reserve changes for the three and six months ended March 31, 2014 and March 31, 2013 were as follows:
		Three months ended												Six months ended

	Amounts payable or recoverable for reinsurance on paid and unpaid claims are not subject to periodic or maximum limits. During the three and six months ended March 31, 2014 and March 31, 2013, the Company did not write off any reinsurance balances. During the three and six months ended March 31, 2014 and March 31, 2013, the Company did not commute any ceded reinsurance.
	No policies issued by the Company have been reinsured with any foreign company, which is controlled, either directly or indirectly, by a party not primarily engaged in the business of insurance.
	The Company has not entered into any reinsurance agreements in which the reinsurer may unilaterally cancel any reinsurance for reasons other than non-payment of premiums or other similar credit issues.

	FSRCI
	Effective December 31, 2012, FGL Insurance entered into a reinsurance treaty with FSRCI, an indirectly wholly-owned subsidiary of HGI, FGL’s parent, whereby FGL ceded 10% of its June 30, 2012 in-force annuity block business not already reinsured on a funds withheld basis. Under the terms of the agreement, FSRCI paid FGL Insurance an initial ceding allowance of $15.0. A study prepared by an independent third party actuarial firm determined that the initial ceding allowance of $15.0 is a fair and reasonable valuation. The coinsurance agreement was on a funds withheld basis, meaning that funds were withheld by FGL Insurance from the coinsurance premium owed to FSRCI as collateral for FSRCI’s payment obligations.

	Insurance Subsidiary Financial Information and Regulatory Matters
	The Company’s insurance subsidiaries file financial statements with state insurance regulatory authorities and the National Association of Insurance Commissioners (“NAIC”) that are prepared in accordance with Statutory Accounting Principles (“SAP”) prescribed or permitted by such authorities, which may vary materially from GAAP. Prescribed SAP includes the Accounting Practices and Procedures Manual of the NAIC as well as state laws, regulations and administrative rules. Permitted SAP encompasses all accounting practices not so prescribed. The principal differences between statutory financial statements and financial statements prepared in accordance with GAAP are that statutory financial statements do not reflect DAC and VOBA, some bond portfolios may be carried at amortized cost, assets and liabilities are presented net of reinsurance, contractholder liabilities are generally valued using more conservative assumptions and certain assets are non-admitted. Accordingly, statutory operating results and statutory capital and surplus may differ substantially from amounts reported in the GAAP basis financial statements for comparable items
	On November 1, 2013, FGL Insurance re-domesticated from Maryland to Iowa. After re-domestication, FGL Insurance elected to apply Iowa-prescribed accounting practices that permit Iowa-domiciled insurers to report equity call options used to economically hedge FIA index credits at amortized cost for statutory accounting purposes and to calculate FIA statutory reserves such that index credit returns will be included in the reserve only after crediting to the annuity contract. This resulted in an $11.5 increase to statutory capital and surplus at December 31, 2013. Also, the Iowa Insurance Division granted FGL Insurance a permitted statutory accounting practice to reclassify its negative unassigned surplus balance of $805.8 (unaudited) to additional paid in capital as of April 6, 2011, the date the Company acquired FGL Insurance, which will have the effect of setting FGL Insurance’s statutory unassigned surplus to zero as of this date. The prescribed and permitted statutory accounting practice has no impact on the Company’s consolidated financial statements which are prepared in accordance with GAAP.
	FGL Insurance’s statutory carrying value of Raven Reinsurance Company ("Raven Re") reflects the effect of permitted practices Raven Re received. Raven Re is permitted to treat the available amount of a letter of credit as an admitted asset. Raven Re is also permitted to follow Iowa prescribed statutory accounting practice for its reserves on reinsurance assumed from FGL Insurance. Without such permitted statutory accounting practices Raven Re’s statutory capital and surplus would be negative and its risk-based capital would fall below the minimum regulatory requirements. As of March 31, 2014, FGL NY Insurance does not follow any prescribed or permitted statutory accounting practices that differ from the NAIC’s statutory accounting practices.
	On October 7, 2013 the New York State Department of Financial Services (“NYDFS”) announced an agreement with Philip A. Falcone, the Chairman and Chief Executive Officer of HGI (FGL’s ultimate parent company), HGI, FGLH and FGL NY Insurance that Mr. Falcone will not exercise control, within the meaning of New York insurance law, over FGL NY Insurance or any other New York-licensed insurer for seven years (the “NYDFS Commitment”). Under the NYDFS Commitment agreement, FGLH agreed to maintain FGL NY Insurance’s risk based capital ("RBC") level at no less than 225% company action level RBC ratio, and established a trust account funded with $18.5 of cash or eligible securities to support that agreement.

	Offsetting Assets and Liabilities
	In December 2011, the Financial Accounting Standards Board (“FASB”) issued amended disclosure requirements for offsetting financial assets and financial liabilities to allow investors to better compare financial statements prepared under GAAP with financial statements prepared under International Financial Reporting Standards. The new standards are effective for the Company beginning in the first quarter of its fiscal year ending September 30, 2014. ASU 2011-11 Disclosures about Offsetting Assets and Liabilities - was adopted by the Company effective October 1, 2013. FGL does not offset any of its derivative transactions, including bifurcated embedded derivatives, in its statement of financial position. The Company only enters into purchased equity options and long futures contracts. The Company has not entered into any repurchase and reverse repurchase agreements or securities borrowing and lending transactions. Accordingly, no additional disclosures are required.
	Investments in Qualified Affordable Housing Projects
	In January 2014, the FASB issued amended guidance which allows investors in Low Income Housing Tax Credit (“LIHTC”) programs that meet specified conditions to present the net tax benefits (net of the amortization of the cost of the investment) within income tax expense. The cost of the investments that meet the specified conditions will be amortized in proportion to (and over the same period as) the total expected tax benefits, including the tax credits and other tax benefits, as they are realized on the tax return. The guidance is required to be applied retrospectively, if investors elect the proportional amortization method. However, if investors have existing LIHTC investments accounted for under the effective-yield method at adoption, they may continue to apply that method for those existing investments.  The new standards will become effective for the Company beginning in the first quarter of its fiscal year ending September 30, 2016.  The Company is currently evaluating the impact of this new accounting guidance on its consolidated financial position and results of operations.
