Formation of Genworth and Basis of Presentation	'
	(1) Formation of Genworth and Basis of Presentation
	Genworth Holdings, Inc. (“Genworth Holdings”) (formerly known as Genworth Financial, Inc.) was incorporated in Delaware on October 23, 2003. On April 1, 2013, Genworth Holdings completed a holding company reorganization pursuant to which Genworth Holdings became a direct, 100% owned subsidiary of a new public holding company it had formed. The new public holding company was incorporated in Delaware on December 5, 2012, in connection with the reorganization, under the name Sub XLVI, Inc., and was renamed Genworth Financial, Inc. upon the completion of the reorganization.
	To implement the reorganization, Genworth Holdings formed New Genworth and New Genworth, in turn, formed Sub XLII, Inc. (“Merger Sub”). The holding company structure was implemented pursuant to Section 251(g) of the General Corporation Law of the State of Delaware (“DGCL”) by the merger of Merger Sub with and into Genworth Holdings (the “Merger”). Genworth Holdings survived the Merger as a direct, wholly-owned subsidiary of New Genworth and each share of Genworth Holdings Class A Common Stock, par value $0.001 per share (“Genworth Holdings Class A Common Stock”), issued and outstanding immediately prior to the Merger and each share of Genworth Holdings Class A Common Stock held in the treasury of Genworth Holdings immediately prior to the Merger converted into one issued and outstanding or treasury, as applicable, share of New Genworth Class A Common Stock, par value $0.001 per share, having the same designations, rights, powers and preferences and the qualifications, limitations and restrictions as the Genworth Holdings Class A Common Stock being converted.
	Immediately after the consummation of the Merger, New Genworth had the same authorized, outstanding and treasury capital stock as Genworth Holdings immediately prior to the Merger. Each share of New Genworth common stock outstanding immediately prior to the Merger was cancelled.
	Pursuant to Section 251(g) of the DGCL, the Merger did not require a vote of the stockholders of Genworth Holdings. Effective upon the consummation of the Merger, New Genworth adopted an amended and restated certificate of incorporation and amended and restated bylaws that were identical to those of Genworth Holdings immediately prior to the consummation of the Merger (other than provisions regarding certain technical matters, as permitted by Section 251(g) of the DGCL). New Genworth’s directors and executive officers immediately after the consummation of the Merger were the same as the directors and executive officers of Genworth Holdings immediately prior to the consummation of the Merger. Immediately after the consummation of the Merger, New Genworth had, on a consolidated basis, the same assets, businesses and operations as Genworth Holdings had immediately prior to the consummation of the Merger.
	On April 1, 2013, in connection with the reorganization, immediately following the consummation of the Merger, Genworth Holdings distributed to New Genworth (as its sole stockholder), through a dividend (the “Distribution”), the 84.6% membership interest in one of its subsidiaries (Genworth Mortgage Holdings, LLC (“GMHL”)) that it held directly, and 100% of the shares of another of its subsidiaries (Genworth Mortgage Holdings, Inc. (“GMHI”)), that held the remaining 15.4% of outstanding membership interests of GMHL. At the time of the Distribution, GMHL and GMHI together owned (directly or indirectly) 100% of the shares or other equity interests of all of the subsidiaries that conducted Genworth Holdings’ U.S. mortgage insurance business (these subsidiaries also owned the subsidiaries that conducted Genworth Holdings’ European mortgage insurance business). As part of the comprehensive U.S. mortgage insurance capital plan, on April 1, 2013, immediately prior to the Distribution, Genworth Holdings contributed $100 million to the U.S. mortgage insurance subsidiaries.
	The accompanying condensed financial statements include on a consolidated basis the accounts of: (a) for the periods prior to April 1, 2013, Genworth Holdings and the affiliated companies in which it held a majority equity interest or where it was the primary beneficiary of a variable interest entity and (b) for the periods from and after April 1, 2013, New Genworth and the affiliated companies in which it held a majority voting interest or where it was the primary beneficiary of a variable interest entity. All intercompany accounts and transactions have been eliminated in consolidation.
	References to “Genworth,” the “Company,” “we” or “our” in the accompanying condensed consolidated financial statements and these notes thereto have the following meanings, unless the context otherwise requires:
		•	For periods prior to April 1, 2013: Genworth Holdings and its subsidiaries
		•	For periods from and after April 1, 2013: New Genworth and its subsidiaries
	We have the following operating segments:
		•	U.S. Life Insurance. We offer and manage a variety of insurance and fixed annuity products. Our primary insurance products include life insurance, long-term care insurance and fixed annuities.
		•	International Mortgage Insurance. We are a leading provider of mortgage insurance products and related services in Canada and Australia and also participate in select European and other countries. Our products predominantly insure prime-based, individually underwritten residential mortgage loans, also known as flow mortgage insurance. We also selectively provide mortgage insurance on a structured, or bulk, basis that aids in the sale of mortgages to the capital markets and helps lenders manage capital and risk. Additionally, we offer services, analytical tools and technology that enable lenders to operate efficiently and manage risk.
		•	U.S. Mortgage Insurance. In the United States, we offer mortgage insurance products predominantly insuring prime-based, individually underwritten residential mortgage loans, also known as flow mortgage insurance. We selectively provide mortgage insurance on a bulk basis with essentially all of our bulk writings prime-based. Additionally, we offer services, analytical tools and technology that enable lenders to operate efficiently and manage risk.
		•	International Protection. We are a leading provider of payment protection coverages (referred to as lifestyle protection) in multiple European countries and have operations in select other countries. Our lifestyle protection insurance products primarily help consumers meet specified payment obligations should they become unable to pay due to accident, illness, involuntary unemployment, disability or death.
		•	Runoff. The Runoff segment includes the results of non-strategic products which are no longer actively sold. Our non-strategic products primarily include our variable annuity, variable life insurance, institutional, corporate-owned life insurance and other accident and health insurance products. Institutional products consist of: funding agreements, funding agreements backing notes (“FABNs”) and guaranteed investment contracts (“GICs”). In January 2011, we discontinued new sales of retail and group variable annuities while continuing to service our existing blocks of business.
	We also have Corporate and Other activities which include debt financing expenses that are incurred at the Genworth Holdings holding company level, unallocated corporate income and expenses, eliminations of inter-segment transactions and the results of other businesses that are managed outside of our operating segments.
	On March 27, 2013, we announced that we had agreed to sell our wealth management business to AqGen Liberty Acquisition, Inc., a subsidiary of AqGen Liberty Holdings LLC, a partnership of Aquiline Capital Partners and Genstar Capital, for approximately $412 million. Historically, this business had been reported as a separate segment. As a result of the sale agreement, the financial statements and other disclosures herein have been revised to reclassify this business as discontinued operations and report its financial position, results of operations and cash flows separately for all periods presented. The sale closed on August 30, 2013 and we received net proceeds of approximately $360 million. Also included in discontinued operations was our tax and advisor unit, Genworth Financial Investment Services, which was part of our wealth management business until the closing of its sale on April 2, 2012. See note 10 for additional information related to discontinued operations.
	The accompanying condensed consolidated financial statements are unaudited and have been prepared in accordance with U.S. generally accepted accounting principles (“U.S. GAAP”) and rules and regulations of the U.S. Securities and Exchange Commission (“SEC”). Preparing financial statements in conformity with U.S. GAAP requires us to make estimates and assumptions that affect reported amounts and related disclosures. Actual results could differ from those estimates. These condensed consolidated financial statements include all adjustments (including normal recurring adjustments) considered necessary by management to present a fair statement of the financial position, results of operations and cash flows for the periods presented. The results reported in these condensed consolidated financial statements should not be regarded as necessarily indicative of results that may be expected for the entire year. The condensed consolidated financial statements included herein should be read in conjunction with the audited consolidated financial statements and related notes contained in our Current Report on Form 8-K filed on May 30, 2013, which reflected the reclassification of our wealth management business as discontinued operations, adjustments to correct an error related to premium refund accrual in our U.S. mortgage insurance business, the addition of a footnote in the notes to the consolidated financial statements that provides required supplemental guarantor financial information related to certain guarantees we gave in connection with the reorganization in which we became the parent company to Genworth Holdings and the addition of certain disclosures about offsetting assets and liabilities required by newly adopted accounting guidance. Certain prior year amounts have been reclassified to conform to the current year presentation.

Accounting Changes	'
	(2) Accounting Changes
	Accounting Pronouncements Recently Adopted
	On July 17, 2013, we adopted new accounting guidance to provide additional flexibility in the benchmark interest rates used when applying hedge accounting. The new guidance permits the use of the Federal Funds Effective Swap Rate as a benchmark interest rate for hedge accounting purposes and removes certain restrictions on being able to apply hedge accounting for similar hedges using different benchmark interest rates. The adoption of this accounting guidance did not have a material impact on our consolidated financial statements.
	On January 1, 2013, we adopted new accounting guidance for disclosures about offsetting assets and liabilities. This guidance requires an entity to disclose information about offsetting and related arrangements to enable users to understand the effect of those arrangements on its financial position. The adoption of this accounting guidance impacted our disclosures only and did not impact our consolidated results.
	On January 1, 2013, we adopted new accounting guidance related to the presentation of the reclassification of items out of accumulated other comprehensive income into net income. The adoption of this accounting guidance impacted our disclosures only and did not impact our consolidated results.
	Accounting Pronouncements Not Yet Adopted
	In June 2013, the Financial Accounting Standards Board issued new accounting guidance on the scope, measurement and disclosure requirements for investment companies. The new guidance clarifies the characteristics of an investment company, provides comprehensive guidance for assessing whether an entity is an investment company, requires investment companies to measure noncontrolling ownership interest in other investment companies at fair value rather than using the equity method of accounting and requires additional disclosures. These new requirements will be effective for us on January 1, 2014 and are not expected to have a material impact on our consolidated financial statements.

	We generally intend to hold securities in unrealized loss positions until they recover. However, from time to time, our intent on an individual security may change, based upon market or other unforeseen developments. In such instances, we sell securities in the ordinary course of managing our portfolio to meet diversification, credit quality, yield and liquidity requirements. If a loss is recognized from a sale subsequent to a balance sheet date due to these unexpected developments, the loss is recognized in the period in which we determined that we have the intent to sell the securities or it is more likely than not that we will be required to sell the securities prior to recovery. The aggregate fair value of securities sold at a loss during the three months ended September 30, 2013 and 2012 was $407 million and $228 million, respectively, which was approximately 93% and 96%, respectively, of book value. The aggregate fair value of securities sold at a loss during the nine months ended September 30, 2013 and 2012 was $1,293 million and $911 million, respectively, which was approximately 90% and 93%, respectively, of book value.

(1)	Amounts included $16 million of unrealized losses on other-than-temporarily impaired securities.
(2)	Amounts included $17 million of unrealized losses on other-than-temporarily impaired securities.
(3)	Amounts that have been in a continuous loss position for 12 months or more included $16 million of unrealized losses on other-than-temporarily impaired securities.
As indicated in the table above, the majority of the securities in a continuous unrealized loss position for less than 12 months were investment grade and less than 20% below cost. These unrealized losses were primarily attributable to lower credit ratings since acquisition for corporate securities across various industry sectors. For securities that have been in a continuous unrealized loss for less than 12 months, the average fair value percentage below cost was approximately 6% as of September 30, 2013.
Fixed Maturity Securities In A Continuous Unrealized Loss Position For 12 Months Or More
Of the $125 million of unrealized losses on fixed maturity securities in a continuous unrealized loss for 12 months or more that were less than 20% below cost, the weighted-average rating was “BBB-” and approximately 66% of the unrealized losses were related to investment grade securities as of September 30, 2013. These unrealized losses were attributable to the lower credit ratings for these securities since acquisition, primarily associated with corporate and structured securities in the finance and insurance sector. The average fair value percentage below cost for these securities was approximately 9% as of September 30, 2013. See below for additional discussion related to fixed maturity securities that have been in a continuous loss position for 12 months or more with a fair value that was more than 20% below cost.
The following tables present the concentration of gross unrealized losses and fair values of fixed maturity securities that were more than 20% below cost and in a continuous loss position for 12 months or more by asset class as of September 30, 2013:

For all securities in an unrealized loss position, we expect to recover the amortized cost based on our estimate of cash flows to be collected. We do not intend to sell and it is not more likely than not that we will be required to sell these securities prior to recovering our amortized cost. See the following for further discussion of gross unrealized losses by asset class.
U. S. government, agencies and government-sponsored enterprises
As indicated in the table above, $43 million of gross unrealized losses were related to a U.S. government, agencies and government-sponsored enterprises security that has been in a continuous loss position for more than 12 months and was greater than 20% below cost. The unrealized losses for the U.S. government, agencies and government-sponsored enterprises security represents a long-term, zero coupon Treasury bond. An increase in Treasury yields since the bond was purchased resulted in a decrease in the market value of this security. We expect that this security will accrete up to par value over time.
Corporate Debt Securities
The following tables present the concentration of gross unrealized losses and fair values related to corporate debt fixed maturity securities that were more than 20% below cost and in a continuous loss position for 12 months or more by industry as of September 30, 2013:

The total unrealized losses of $19 million for corporate fixed maturity securities presented in the tables above related to issuers in the finance and insurance sector that were 20% below cost on average. Given the current market conditions, including current financial industry events and uncertainty around global economic conditions, the fair value of these debt securities has declined due to credit spreads that have widened since acquisition. In our examination of these securities, we considered all available evidence, including the issuers’ financial condition and current industry events to develop our conclusion on the amount and timing of the cash flows expected to be collected. Based on this evaluation, we determined that the unrealized losses on these debt securities represented temporary impairments as of September 30, 2013. Of the $19 million of unrealized losses related to the finance and insurance industry, $18 million related to financial hybrid securities on which a debt impairment model was employed. Most of our hybrid securities retained a credit rating of investment grade. The fair value of these hybrid securities has been impacted by credit spreads that have widened since acquisition and reflect uncertainty surrounding the extent and duration of government involvement, potential capital restructuring of these institutions, and continued but diminishing risk that income payments may be deferred. We continue to receive our contractual payments and expect to fully recover our amortized cost.
We expect that our investments in corporate securities will continue to perform in accordance with our expectations about the amount and timing of estimated cash flows. Although we do not anticipate such events, it is at least reasonably possible that issuers of our investments in corporate securities will perform worse than current expectations. Such events may lead us to recognize write-downs within our portfolio of corporate securities in the future.
Structured Securities
Of the $74 million of unrealized losses related to structured securities that have been in an unrealized loss position for 12 months or more and were more than 20% below cost, $11 million related to other-than-temporarily impaired securities where the unrealized losses represented the portion of the other-than-temporary impairment recognized in OCI. The extent and duration of the unrealized loss position on our structured securities was primarily due to the ongoing concern and uncertainty about the residential and commercial real estate market and unemployment, resulting in credit spreads that have widened since acquisition. Additionally, the fair value of certain structured securities has been significantly impacted from high risk premiums being incorporated into the valuation as a result of the amount of potential losses that may be absorbed by the security in the event of additional deterioration in the U.S. housing market.
While we considered the length of time each security had been in an unrealized loss position, the extent of the unrealized loss position and any significant declines in fair value subsequent to the balance sheet date in our evaluation of impairment for each of these individual securities, the primary factor in our evaluation of impairment is the expected performance for each of these securities. Our evaluation of expected performance is based on the historical performance of the associated securitization trust as well as the historical performance of the underlying collateral. Our examination of the historical performance of the securitization trust included consideration of the following factors for each class of securities issued by the trust: i) the payment history, including failure to make scheduled payments; ii) current payment status; iii) current and historical outstanding balances; iv) current levels of subordination and losses incurred to date; and v) characteristics of the underlying collateral. Our examination of the historical performance of the underlying collateral included: i) historical default rates, delinquency rates, voluntary and involuntary prepayments and severity of losses, including recent trends in this information; ii) current payment status; iii) loan to collateral value ratios, as applicable; iv) vintage; and v) other underlying characteristics such as current financial condition.
We used our assessment of the historical performance of both the securitization trust and the underlying collateral for each security, along with third-party sources, when available, to develop our best estimate of cash flows expected to be collected. These estimates reflect projections for future delinquencies, prepayments, defaults and losses for the assets that collateralize the securitization trust and are used to determine the expected cash flows for our security, based on the payment structure of the trust. Our projection of expected cash flows is primarily based on the expected performance of the underlying assets that collateralize the securitization trust and is not directly impacted by the rating of our security. While we consider the rating of the security as an indicator of the financial condition of the issuer, this factor does not have a significant impact on our expected cash flows for each security. In limited circumstances, our expected cash flows include expected payments from reliable financial guarantors where we believe the financial guarantor will have sufficient assets to pay claims under the financial guarantee when the cash flows from the securitization trust are not sufficient to make scheduled payments. We then discount the expected cash flows using the effective yield of each security to determine the present value of expected cash flows.
Based on this evaluation, the present value of expected cash flows was greater than or equal to the amortized cost for each security. Accordingly, we determined that the unrealized losses on each of our structured securities represented temporary impairments as of September 30, 2013.
Despite the considerable analysis and rigor employed on our structured securities, it is at least reasonably possible that the underlying collateral of these investments will perform worse than current market expectations. Such events may lead to adverse changes in cash flows on our holdings of structured securities and future write-downs within our portfolio of structured securities.
The following table presents the gross unrealized losses and fair values of our investment securities, aggregated by investment type and length of time that individual investment securities have been in a continuous unrealized loss position, as of December 31, 2012:

As of September 30, 2013, $5,529 million of our investments (excluding mortgage-backed and asset-backed securities) were subject to certain call provisions.
As of September 30, 2013, securities issued by utilities and energy, finance and insurance, and consumer—non-cyclical industry groups represented approximately 24%, 19% and 12%, respectively, of our domestic and foreign corporate fixed maturity securities portfolio. No other industry group comprised more than 10% of our investment portfolio. This portfolio is widely diversified among various geographic regions in the United States and internationally, and is not dependent on the economic stability of one particular region.
As of September 30, 2013, we did not hold any fixed maturity securities in any single issuer, other than securities issued or guaranteed by the U.S. government, which exceeded 10% of stockholders’ equity.
(e) Commercial Mortgage Loans
Our mortgage loans are collateralized by commercial properties, including multi-family residential buildings. The carrying value of commercial mortgage loans is stated at original cost net of prepayments, amortization and allowance for loan losses.

As of September 30, 2013 and December 31, 2012, we had no commercial mortgage loans that were past due for more than 90 days and still accruing interest. We did not have any commercial mortgage loans that were past due for less than 90 days on non-accrual status as of September 30, 2013 and December 31, 2012.
As of and for the nine months ended September 30, 2013 and the year ended December 31, 2012, we modified or extended 26 and 38 commercial mortgage loans, respectively, with a total carrying value of $146 million and $279 million, respectively. All of these modifications or extensions were based on current market interest rates, did not result in any forgiveness in the outstanding principal amount owed by the borrower and were not considered troubled debt restructurings.

As of September 30, 2013, we had individually impaired commercial mortgage loans included within the retail property type with a recorded investment of $1 million, an unpaid principal balance of $3 million, charge-offs of $2 million and an average recorded investment of $1 million. As of September 30, 2013, we also had individually impaired commercial mortgage loans included within the industrial property type with a recorded investment of $1 million, an unpaid principal balance of $2 million, charge-offs of $1 million and an average recorded investment of $1 million. As of December 31, 2012, we had no individually impaired commercial mortgage loans.
In evaluating the credit quality of commercial mortgage loans, we assess the performance of the underlying loans using both quantitative and qualitative criteria. Certain risks associated with commercial mortgage loans can be evaluated by reviewing both the loan-to-value and debt service coverage ratio to understand both the probability of the borrower not being able to make the necessary loan payments as well as the ability to sell the underlying property for an amount that would enable us to recover our unpaid principal balance in the event of default by the borrower. The average loan-to-value ratio is based on our most recent estimate of the fair value for the underlying property which is evaluated at least annually and updated more frequently if necessary to better indicate risk associated with the loan. A lower loan-to-value indicates that our loan value is more likely to be recovered in the event of default by the borrower if the property was sold. The debt service coverage ratio is based on “normalized” annual net operating income of the property compared to the payments required under the terms of the loan. Normalization allows for the removal of annual one-time events such as capital expenditures, prepaid or late real estate tax payments or non-recurring third-party fees (such as legal, consulting or contract fees). This ratio is evaluated at least annually and updated more frequently if necessary to better indicate risk associated with the loan. A higher debt service coverage ratio indicates the borrower is less likely to default on the loan. The debt service coverage ratio should not be used without considering other factors associated with the borrower, such as the borrower’s liquidity or access to other resources that may result in our expectation that the borrower will continue to make the future scheduled payments.

As of September 30, 2013, the total recorded investment of our restricted commercial mortgage loans of $291 million was current. Of our restricted commercial mortgage loans as of December 31, 2012, $337 million were current and $5 million were past due for more than 90 days and still accruing interest.
As of September 30, 2013 and December 31, 2012, the total recorded investment of restricted commercial mortgage loans of $291 million and $342 million, respectively, related to loans not individually impaired that were evaluated collectively for impairment. There was no provision for credit losses recorded during the three or nine months ended September 30, 2013 or 2012 related to restricted commercial mortgage loans.
In evaluating the credit quality of restricted commercial mortgage loans, we assess the performance of the underlying loans using both quantitative and qualitative criteria. The risks associated with restricted commercial mortgage loans can typically be evaluated by reviewing both the loan-to-value and debt service coverage ratio to understand both the probability of the borrower not being able to make the necessary loan payments as well as the ability to sell the underlying property for an amount that would enable us to recover our unpaid principal balance in the event of default by the borrower. The average loan-to-value ratio is based on our most recent estimate of the fair value for the underlying property which is evaluated at least annually and updated more frequently if necessary to better indicate risk associated with the loan. A lower loan-to-value indicates that our loan value is more likely to be recovered in the event of default by the borrower if the property was sold. The debt service coverage ratio is based on “normalized” annual net operating income of the property compared to the payments required under the terms of the loan. Normalization allows for the removal of annual one-time events such as capital expenditures, prepaid or late real estate tax payments or non-recurring third-party fees (such as legal, consulting or contract fees). This ratio is evaluated at least annually and updated more frequently if necessary to better indicate risk associated with the loan. A higher debt service coverage ratio indicates the borrower is less likely to default on the loan. The debt service coverage ratio should not be used without considering other factors associated with the borrower, such as the borrower’s liquidity or access to other resources that may result in our expectation that the borrower will continue to make the future scheduled payments.

(g) Restricted Other Invested Assets Related To Securitization Entities
We have consolidated securitization entities that hold certain investments that are recorded as restricted other invested assets related to securitization entities. The consolidated securitization entities hold certain investments as trading securities whereby the changes in fair value are recorded in current period income (loss). The trading securities comprise asset-backed securities, including residual interest in certain policy loan securitization entities and highly rated bonds that are primarily backed by credit card receivables.

Derivative Instruments	'
	(5) Derivative Instruments
	Our business activities routinely deal with fluctuations in interest rates, equity prices, currency exchange rates and other asset and liability prices. We use derivative instruments to mitigate or reduce certain of these risks. We have established policies for managing each of these risks, including prohibitions on derivatives market-making and other speculative derivatives activities. These policies require the use of derivative instruments in concert with other techniques to reduce or mitigate these risks. While we use derivatives to mitigate or reduce risks, certain derivatives do not meet the accounting requirements to be designated as hedging instruments and are denoted as “derivatives not designated as hedges” in the following disclosures. For derivatives that meet the accounting requirements to be designated as hedges, the following disclosures for these derivatives are denoted as “derivatives designated as hedges,” which include both cash flow and fair value hedges.

Cash Flow Hedges
Certain derivative instruments are designated as cash flow hedges. The changes in fair value of these instruments are recorded as a component of OCI. We designate and account for the following as cash flow hedges when they have met the effectiveness requirements: (i) various types of interest rate swaps to convert floating rate investments to fixed rate investments; (ii) various types of interest rate swaps to convert floating rate liabilities into fixed rate liabilities; (iii) receive U.S. dollar fixed on foreign currency swaps to hedge the foreign currency cash flow exposure of foreign currency denominated investments; (iv) forward starting interest rate swaps to hedge against changes in interest rates associated with future fixed rate bond purchases and/or interest income; (v) forward bond purchase commitments to hedge against the variability in the anticipated cash flows required to purchase future fixed rate bonds; and (vi) other instruments to hedge the cash flows of various forecasted transactions.
The following table provides information about the pre-tax income (loss) effects of cash flow hedges for the three months ended September 30, 2013:

The total of derivatives designated as cash flow hedges of $1,442 million, net of taxes, recorded in stockholders’ equity as of September 30, 2013 is expected to be reclassified to future net income, concurrently with and primarily offsetting changes in interest expense and interest income on floating rate instruments and interest income on future fixed rate bond purchases. Of this amount, $37 million, net of taxes, is expected to be reclassified to net income in the next 12 months. Actual amounts may vary from this amount as a result of market conditions. All forecasted transactions associated with qualifying cash flow hedges are expected to occur by 2047. No amounts were reclassified to net income during the nine months ended September 30, 2013 in connection with forecasted transactions that were no longer considered probable of occurring.
Fair Value Hedges
Certain derivative instruments are designated as fair value hedges. The changes in fair value of these instruments are recorded in net income. In addition, changes in the fair value attributable to the hedged portion of the underlying instrument are reported in net income. We designate and account for the following as fair value hedges when they have met the effectiveness requirements: (i) interest rate swaps to convert fixed rate investments to floating rate investments; (ii) interest rate swaps to convert fixed rate liabilities into floating rate liabilities; (iii) cross currency swaps to convert non-U.S. dollar fixed rate liabilities to floating rate U.S. dollar liabilities; and (iv) other instruments to hedge various fair value exposures of investments.
There were no pre-tax income (loss) effects of fair value hedges and related hedged items for the three months ended September 30, 2013.

The difference between the gain (loss) recognized for the derivative instrument and the hedged item presented above represents the net ineffectiveness of the fair value hedging relationships. The other impacts presented above represent the net income effects of the derivative instruments that are presented in the same location as the income (loss) activity from the hedged item. There were no amounts excluded from the measurement of effectiveness.
Derivatives Not Designated As Hedges
We also enter into certain non-qualifying derivative instruments such as: (i) interest rate swaps and financial futures to mitigate interest rate risk as part of managing regulatory capital positions; (ii) credit default swaps to enhance yield and reproduce characteristics of investments with similar terms and credit risk; (iii) equity index options, equity return swaps, interest rate swaps and financial futures to mitigate the risks associated with liabilities that have guaranteed minimum benefits and fixed index annuities; (iv) interest rate swaps where the hedging relationship does not qualify for hedge accounting; (v) credit default swaps to mitigate loss exposure to certain credit risk; (vi) foreign currency forward contracts and options to mitigate currency risk associated with investments and future dividends and other cash flows from certain foreign subsidiaries to our holding company; and (vii) equity index options to mitigate certain macroeconomic risks associated with certain foreign subsidiaries. Additionally, we provide GMWBs on certain variable annuities that are required to be bifurcated as embedded derivatives. We also offer fixed index annuity products and have reinsurance agreements with certain features that are required to be bifurcated as embedded derivatives.
We also have derivatives related to securitization entities where we were required to consolidate the related securitization entity as a result of our involvement in the structure. The counterparties for these derivatives typically only have recourse to the securitization entity. The interest rate swaps used for these entities are typically used to effectively convert the interest payments on the assets of the securitization entity to the same basis as the interest rate on the borrowings issued by the securitization entity. Credit default swaps are utilized in certain securitization entities to enhance the yield payable on the borrowings issued by the securitization entity and also include a settlement feature that allows the securitization entity to provide the par value of assets in the securitization entity for the amount of any losses incurred under the credit default swap.

Derivative Counterparty Credit Risk
Most of our derivative arrangements with counterparties require the posting of collateral upon meeting certain net exposure thresholds. For derivatives related to securitization entities, there are no arrangements that require either party to provide collateral and the recourse of the derivative counterparty is typically limited to the assets held by the securitization entity and there is no recourse to any entity other than the securitization entity.
The following tables present additional information about derivative assets and liabilities subject to an enforceable master netting arrangement as of the dates indicated:

Except for derivatives related to securitization entities, almost all of our master swap agreements contain credit downgrade provisions that allow either party to assign or terminate derivative transactions if the other party’s long-term unsecured debt rating or financial strength rating is below the limit defined in the applicable agreement. If the downgrade provisions had been triggered as of September 30, 2013 and December 31, 2012, we could have been allowed to claim or required to disburse up to the net amounts shown in the last column of the charts above. The charts above exclude embedded derivatives and derivatives related to securitization entities as those derivatives are not subject to master netting arrangements.
Credit Derivatives
We sell protection under single name credit default swaps and credit default swap index tranches in combination with purchasing securities to replicate characteristics of similar investments based on the credit quality and term of the credit default swap. Credit default triggers for both indexed reference entities and single name reference entities follow the Credit Derivatives Physical Settlement Matrix published by the International Swaps and Derivatives Association. Under these terms, credit default triggers are defined as bankruptcy, failure to pay or restructuring, if applicable. Our maximum exposure to credit loss equals the notional value for credit default swaps. In the event of default for credit default swaps, we are typically required to pay the protection holder the full notional value less a recovery rate determined at auction.
In addition to the credit derivatives discussed above, we also have credit derivative instruments related to securitization entities that we consolidate. These derivatives represent a customized index of reference entities with specified attachment points for certain derivatives. The credit default triggers are similar to those described above. In the event of default, the securitization entity will provide the counterparty with the par value of assets held in the securitization entity for the amount of incurred loss on the credit default swap. The maximum exposure to loss for the securitization entity is the notional value of the derivatives. Certain losses on these credit default swaps would be absorbed by the third-party noteholders of the securitization entity and the remaining losses on the credit default swaps would be absorbed by our portion of the notes issued by the securitization entity.

Fair_Value_of_Financial_Instru

Fair Value of Financial Instruments	9 Months Ended

Fair Value of Financial Instruments	'
	(6) Fair Value of Financial Instruments
	Assets and liabilities that are reflected in the accompanying consolidated financial statements at fair value are not included in the following disclosure of fair value. Such items include cash and cash equivalents, investment securities, separate accounts, securities held as collateral and derivative instruments. Other financial assets and liabilities—those not carried at fair value—are discussed below. Apart from certain of our borrowings and certain marketable securities, few of the instruments discussed below are actively traded and their fair values must often be determined using models. The fair value estimates are made at a specific point in time, based upon available market information and judgments about the financial instruments, including estimates of the timing and amount of expected future cash flows and the credit standing of counterparties. Such estimates do not reflect any premium or discount that could result from offering for sale at one time our entire holdings of a particular financial instrument, nor do they consider the tax impact of the realization of unrealized gains or losses. In many cases, the fair value estimates cannot be substantiated by comparison to independent markets.
	The basis on which we estimate fair value is as follows:
	Commercial mortgage loans. Based on recent transactions and/or discounted future cash flows, using current market rates. Given the limited availability of data related to transactions for similar instruments, we typically classify these loans as Level 3.
	Restricted commercial mortgage loans. Based on recent transactions and/or discounted future cash flows, using current market rates. Given the limited availability of data related to transactions for similar instruments, we typically classify these loans as Level 3.
	Other invested assets. Based on comparable market transactions, discounted future cash flows, quoted market prices and/or estimates using the most recent data available for the related instrument. Primarily represents short-term investments and limited partnerships accounted for under the cost method. The fair value of short-term investments typically does not include significant unobservable inputs and approximate our amortized cost basis. As a result, short-term investments are classified as Level 2. Cost method limited partnerships typically include significant unobservable inputs as a result of being relatively illiquid with limited market activity for similar instruments and are classified as Level 3.
	Long-term borrowings. We utilize available market data when determining fair value of long-term borrowings issued in the U.S. and Canada, which includes data on recent trades for the same or similar financial instruments. Accordingly, these instruments are classified as Level 2 measurements. In cases where market data is not available such as our Australian borrowings, we use broker quotes for which we consider the valuation methodology utilized by the third party, but the valuation typically includes significant unobservable inputs. Accordingly, we classify these borrowings where fair value is based on our consideration of broker quotes as Level 3 measurements.
	Non-recourse funding obligations. We use an internal model to determine fair value using the current floating rate coupon and expected life/final maturity of the instrument discounted using the floating rate index and current market spread assumption, which is estimated based on recent transactions for these instruments or similar instruments as well as other market information or broker provided data. Given these instruments are private and very little market activity exists, our current market spread assumption is considered to have significant unobservable inputs in calculating fair value and, therefore, results in the fair value of these instruments being classified as Level 3.
	Borrowings related to securitization entities. Based on market quotes or comparable market transactions. Some of these borrowings are publicly traded debt securities and are classified as Level 2. Certain borrowings are not publicly traded and are classified as Level 3.
	Investment contracts. Based on expected future cash flows, discounted at current market rates for annuity contracts or institutional products. Given the significant unobservable inputs associated with policyholder behavior and current market rate assumptions used to discount the expected future cash flows, we classify these instruments as Level 3 except for certain funding agreement-backed notes that are traded in the marketplace as a security and are classified as Level 2.

	Recurring Fair Value Measurements
	We have fixed maturity, equity and trading securities, derivatives, embedded derivatives, securities held as collateral, separate account assets and certain other financial instruments, which are carried at fair value. Below is a description of the valuation techniques and inputs used to determine fair value by class of instrument.
	Fixed maturity, equity and trading securities
	The valuations of fixed maturity, equity and trading securities are determined using a market approach, income approach or a combination of the market and income approach depending on the type of instrument and availability of information.
	We utilize certain third-party data providers when determining fair value. We consider information obtained from third-party pricing services (“pricing services”) as well as third-party broker provided prices, or broker quotes, in our determination of fair value. Additionally, we utilize internal models to determine the valuation of securities using an income approach where the inputs are based on third-party provided market inputs. While we consider the valuations provided by pricing services and broker quotes, management determines the fair value of our investment securities after considering all relevant and available information. We also use various methods to obtain an understanding of the valuation methodologies and procedures used by third-party data providers to ensure sufficient understanding to evaluate the valuation data received, including an understanding of the assumptions and inputs utilized to determine the appropriate fair value. For pricing services, we analyze the prices provided by our primary pricing services to other readily available pricing services and perform a detailed review of the assumptions and inputs from each pricing service to determine the appropriate fair value when pricing differences exceed certain thresholds. We also evaluate changes in fair value that are greater than 10% each month to further aid in our review of the accuracy of fair value measurements and our understanding of changes in fair value, with more detailed reviews performed by the asset managers responsible for the related asset class associated with the security being reviewed.
	In general, we first obtain valuations from pricing services. If a price is not supplied by a pricing service, we will typically seek a broker quote. For certain private fixed maturity securities where we do not obtain valuations from pricing services, we utilize an internal model to determine fair value since transactions for identical securities are not readily observable and these securities are not typically valued by pricing services. For all securities, excluding certain private fixed maturity securities, if neither a pricing service nor broker quotes valuation is available, we determine fair value using internal models.
	For pricing services, we obtain an understanding of the pricing methodologies and procedures for each type of instrument. In general, a pricing service does not provide a price for a security if sufficient information is not readily available to determine fair value or if such security is not in the specific sector or class covered by a particular pricing service. Given our understanding of the pricing methodologies and procedures of pricing services, the securities valued by pricing services are typically classified as Level 2 unless we determine the valuation process for a security or group of securities utilizes significant unobservable inputs, which would result in the valuation being classified as Level 3.
	For private fixed maturity securities, we utilize an internal model to determine fair value and utilize public bond spreads by sector, rating and maturity to develop the market rate that would be utilized for a similar public bond. We then add an additional premium, which represents an unobservable input, to the public bond spread to adjust for the liquidity and other features of our private placements. We utilize the estimated market yield to discount the expected cash flows of the security to determine fair value. In certain instances, we utilize price caps for securities where the estimated market yield results in a valuation that may exceed the amount that would be received in a market transaction. We assign each security an internal rating to determine the appropriate public bond spread that should be utilized in the valuation. While we generally consider the public bond spreads by sector and maturity to be observable inputs, we evaluate the similarities of our private placement with the public bonds, any price caps utilized and whether external ratings are available for our private placement to determine whether the spreads utilized would be considered observable inputs. During the second quarter of 2012, we began classifying private securities without an external rating as Level 3. In general, increases (decreases) in credit spreads will decrease (increase) the fair value for our fixed maturity securities. To determine the significance of unobservable inputs, we calculate the impact on the valuation from the unobservable input and will classify a security as Level 3 when the impact on the valuation exceeds 10%.
	For broker quotes, we consider the valuation methodology utilized by the third party, but the valuation typically includes significant unobservable inputs. Accordingly, we classify the securities where fair value is based on our consideration of broker quotes as Level 3 measurements.
	For remaining securities priced using internal models, we maximize the use of observable inputs but typically utilize significant unobservable inputs to determine fair value. Accordingly, the valuations are typically classified as Level 3.

Restricted other invested assets related to securitization entities
We have trading securities related to securitization entities that are classified as restricted other invested assets and are carried at fair value. The trading securities represent asset-backed securities. The valuation for trading securities is determined using a market approach and/or an income approach depending on the availability of information. For certain highly rated asset-backed securities, there is observable market information for transactions of the same or similar instruments, which is provided to us by a third-party pricing service and is classified as Level 2. For certain securities that are not actively traded, we determine fair value after considering third-party broker provided prices or discounted expected cash flows using current yields for similar securities and classify these valuations as Level 3.
Securities lending and derivative counterparty collateral
The fair value of securities held as collateral is primarily based on Level 2 inputs from market information for the collateral that is held on our behalf by the custodian. We determine fair value after considering prices obtained by third-party pricing services.
Contingent consideration
We have certain contingent purchase price payments and receivables related to acquisitions and sales that are recorded at fair value each period. Fair value is determined using an income approach whereby we project the expected performance of the business and compare our projections of the relevant performance metric to the thresholds established in the purchase or sale agreement to determine our expected payments or receipts. We then discount these expected amounts to calculate the fair value as of the valuation date. We evaluate the underlying projections used in determining fair value each period and update these underlying projections when there have been significant changes in our expectations of the future business performance. The inputs used to determine the discount rate and expected payments or receipts are primarily based on significant unobservable inputs and result in the fair value of the contingent consideration being classified as Level 3. An increase in the discount rate or a decrease in expected payments or receipts will result in a decrease in the fair value of contingent consideration.
Separate account assets
The fair value of separate account assets is based on the quoted prices of the underlying fund investments and, therefore, represents Level 1 pricing.
Derivatives
We consider counterparty collateral arrangements and rights of set-off when evaluating our net credit risk exposure to our derivative counterparties. Accordingly, we are permitted to include consideration of these arrangements when determining whether any incremental adjustment should be made for both the counterparty’s and our non-performance risk in measuring fair value for our derivative instruments. As a result of these counterparty arrangements, we determined that any adjustment for credit risk would not be material and we do not record any incremental adjustment for our non-performance risk or the non-performance risk of the derivative counterparty for our derivative assets or liabilities. We determine fair value for our derivatives using an income approach with internal models based on relevant market inputs for each derivative instrument. We also compare the fair value determined using our internal model to the valuations provided by our derivative counterparties with any significant differences or changes in valuation being evaluated further by our derivatives professionals that are familiar with the instrument and market inputs used in the valuation.
Interest rate swaps. The valuation of interest rate swaps is determined using an income approach. The primary input into the valuation represents the forward interest rate swap curve, which is generally considered an observable input, and results in the derivative being classified as Level 2. For certain interest rate swaps, the inputs into the valuation also include the total returns of certain bonds that would primarily be considered an observable input and result in the derivative being classified as Level 2. For certain other swaps, there are features that provide an option to the counterparty to terminate the swap at specified dates. The interest rate volatility input used to value these options would be considered a significant unobservable input and results in the fair value measurement of the derivative being classified as Level 3. These options to terminate the swap by the counterparty are based on forward interest rate swap curves and volatility. As interest rate volatility increases, our valuation of the derivative changes unfavorably.
Interest rate swaps related to securitization entities. The valuation of interest rate swaps related to securitization entities is determined using an income approach. The primary input into the valuation represents the forward interest rate swap curve, which is generally considered an observable input, and results in the derivative being classified as Level 2.
Inflation indexed swaps. The valuation of inflation indexed swaps is determined using an income approach. The primary inputs into the valuation represent the forward interest rate swap curve, the current consumer price index and the forward consumer price index curve, which are generally considered observable inputs, and results in the derivative being classified as Level 2.
Foreign currency swaps. The valuation of foreign currency swaps is determined using an income approach. The primary inputs into the valuation represent the forward interest rate swap curve and foreign currency exchange rates, both of which are considered an observable input, and results in the derivative being classified as Level 2.
Credit default swaps. We have both single name credit default swaps and index tranche credit default swaps. For single name credit default swaps, we utilize an income approach to determine fair value based on using current market information for the credit spreads of the reference entity, which is considered observable inputs based on the reference entities of our derivatives and results in these derivatives being classified as Level 2. For index tranche credit default swaps, we utilize an income approach that utilizes current market information related to credit spreads and expected defaults and losses associated with the reference entities that comprise the respective index associated with each derivative. There are significant unobservable inputs associated with the timing and amount of losses from the reference entities as well as the timing or amount of losses, if any, that will be absorbed by our tranche. Accordingly, the index tranche credit default swaps are classified as Level 3. As credit spreads widen for the underlying issuers comprising the index, the change in our valuation of these credit default swaps will be unfavorable.
Credit default swaps related to securitization entities. Credit default swaps related to securitization entities represent customized index tranche credit default swaps and are valued using a similar methodology as described above for index tranche credit default swaps. We determine fair value of these credit default swaps after considering both the valuation methodology described above as well as the valuation provided by the derivative counterparty. In addition to the valuation methodology and inputs described for index tranche credit default swaps, these customized credit default swaps contain a feature that permits the securitization entity to provide the par value of underlying assets in the securitization entity to settle any losses under the credit default swap. The valuation of this settlement feature is dependent upon the valuation of the underlying assets and the timing and amount of any expected loss on the credit default swap, which is considered a significant unobservable input. Accordingly, these customized index tranche credit default swaps related to securitization entities are classified as Level 3. As credit spreads widen for the underlying issuers comprising the customized index, the change in our valuation of these credit default swaps will be unfavorable.
Equity index options. We have equity index options associated with various equity indices. The valuation of equity index options is determined using an income approach. The primary inputs into the valuation represent forward interest rate volatility and time value component associated with the optionality in the derivative, which are considered significant unobservable inputs in most instances. The equity index volatility surface is determined based on market information that is not readily observable and is developed based upon inputs received from several third-party sources. Accordingly, these options are classified as Level 3. As equity index volatility increases, our valuation of these options changes favorably.
Financial futures. The fair value of financial futures is based on the closing exchange prices. Accordingly, these financial futures are classified as Level 1. The period end valuation is zero as a result of settling the margins on these contracts on a daily basis.
Equity return swaps. The valuation of equity return swaps is determined using an income approach. The primary inputs into the valuation represent the forward interest rate swap curve and underlying equity index values, which are generally considered observable inputs, and results in the derivative being classified as Level 2.
Forward bond purchase commitments. The valuation of forward bond purchase commitments is determined using an income approach. The primary input into the valuation represents the current bond prices and interest rates, which are generally considered an observable input, and results in the derivative being classified as Level 2.
Other foreign currency contracts. We have certain foreign currency options classified as other foreign currency contracts. The valuation of foreign currency options is determined using an income approach. The primary inputs into the valuation represent the forward interest rate swap curve, foreign currency exchange rates, forward interest rate, foreign currency exchange rate volatility, foreign equity index volatility and time value component associated with the optionality in the derivative. As a result of the significant unobservable inputs associated with the forward interest rate, foreign currency exchange rate volatility and foreign equity index volatility inputs, the derivative is classified as Level 3. As foreign currency exchange rate volatility and foreign equity index volatility increases, the change in our valuation of these options will be favorable for purchase options and unfavorable for options sold. We also have foreign currency forward contracts where the valuation is determined using an income approach. The primary inputs into the valuation represent the forward foreign currency exchange rates, which are generally considered observable inputs and results in the derivative being classified as Level 2.
GMWB embedded derivatives
We are required to bifurcate an embedded derivative for certain features associated with annuity products and related reinsurance agreements where we provide a GMWB to the policyholder and are required to record the GMWB embedded derivative at fair value. The valuation of our GMWB embedded derivative is based on an income approach that incorporates inputs such as forward interest rates, equity index volatility, equity index and fund correlation, and policyholder assumptions such as utilization, lapse and mortality. In addition to these inputs, we also consider risk and expense margins when determining the projected cash flows that would be determined by another market participant. While the risk and expense margins are considered in determining fair value, these inputs do not have a significant impact on the valuation. We determine fair value using an internal model based on the various inputs noted above. The resulting fair value measurement from the model is reviewed by the product actuarial, risk and finance professionals each reporting period with changes in fair value also being compared to changes in derivatives and other instruments used to mitigate changes in fair value from certain market risks, such as equity index volatility and interest rates.
For GMWB liabilities, non-performance risk is integrated into the discount rate. Our discount rate used to determine fair value of our GMWB liabilities includes market credit spreads above U.S. Treasury rates to reflect an adjustment for the non-performance risk of the GMWB liabilities. As of September 30, 2013 and December 31, 2012, the impact of non-performance risk resulted in a lower fair value of our GMWB liabilities of $59 million and $89 million, respectively.
To determine the appropriate discount rate to reflect the non-performance risk of the GMWB liabilities, we evaluate the non-performance risk in our liabilities based on a hypothetical exit market transaction as there is no exit market for these types of liabilities. A hypothetical exit market can be viewed as a hypothetical transfer of the liability to another similarly rated insurance company which would closely resemble a reinsurance transaction. Another hypothetical exit market transaction can be viewed as a hypothetical transaction from the perspective of the GMWB policyholder. In determining the appropriate discount rate to incorporate non-performance risk of the GMWB liabilities, we also considered the impacts of state guarantees embedded in the related insurance product as a form of inseparable third-party guarantee. We believe that a hypothetical exit market participant would use a similar discount rate as described above to value the liabilities.
For equity index volatility, we determine the projected equity market volatility using both historical volatility and projected equity market volatility with more significance being placed on projected near-term volatility and recent historical data. Given the different attributes and market characteristics of GMWB liabilities compared to equity index options in the derivative market, the equity index volatility assumption for GMWB liabilities may be different from the volatility assumption for equity index options, especially for the longer dated points on the curve.
Equity index and fund correlations are determined based on historical price observations for the fund and equity index.
For policyholder assumptions, we use our expected lapse, mortality and utilization assumptions and update these assumptions for our actual experience, as necessary. For our lapse assumption, we adjust our base lapse assumption by policy based on a combination of the policyholder’s current account value and GMWB benefit.
We classify the GMWB valuation as Level 3 based on having significant unobservable inputs, with equity index volatility and non-performance risk being considered the more significant unobservable inputs. As equity index volatility increases, the fair value of the GMWB liabilities will increase. Any increase in non-performance risk would increase the discount rate and would decrease the fair value of the GMWB liability. Additionally, we consider lapse and utilization assumptions to be significant unobservable inputs. An increase in our lapse assumption would decrease the fair value of the GMWB liability, whereas an increase in our utilization rate would increase the fair value.
We evaluate the inputs and methodologies used to determine fair value based on how we expect a market participant would determine exit value. As stated above, there is no exit market or market participants for the GMWB embedded derivatives. Accordingly, we evaluate our inputs and resulting fair value based on a hypothetical exit market and hypothetical market participants. A hypothetical exit market could be viewed as a transaction that would closely resemble reinsurance. While reinsurance transactions for this type of product are not an observable input, we consider this type of hypothetical exit market, as appropriate, when evaluating our inputs and determining that our inputs are consistent with that of a hypothetical market participant.
Fixed index annuity embedded derivatives
We offer fixed indexed annuity products where interest is credited to the policyholder’s account balance based on equity index changes. This feature is required to be bifurcated as an embedded derivative and recorded at fair value. Fair value is determined using an income approach where the present value of the excess cash flows above the guaranteed cash flows is used to determine the value attributed to the equity index feature. The inputs used in determining the fair value include policyholder behavior (lapses and withdrawals), near-term equity index volatility, expected future interest credited, forward interest rates and an adjustment to the discount rate to incorporate non-performance risk and risk margins. As a result of our assumptions for policyholder behavior and expected future interest credited being considered significant unobservable inputs, we classify these instruments as Level 3. As lapses and withdrawals increase, the value of our embedded derivative liability will decrease. As expected future interest credited decreases, the value of our embedded derivative liability will decrease.
Borrowings related to securitization entities
We record certain borrowings related to securitization entities at fair value. The fair value of these borrowings is determined using either a market approach or income approach, depending on the instrument and availability of market information. Given the unique characteristics of the securitization entities that issued these borrowings as well as the lack of comparable instruments, we determine fair value considering the valuation of the underlying assets held by the securitization entities and any derivatives, as well as any unique characteristics of the borrowings that may impact the valuation. After considering all relevant inputs, we determine fair value of the borrowings using the net valuation of the underlying assets and derivatives that are backing the borrowings. Accordingly, these instruments are classified as Level 3. Increases in the valuation of the underlying assets or decreases in the derivative liabilities will result in an increase in the fair value of these borrowings.

We review 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 between levels at the beginning fair value for the reporting period in which the changes occur. Given the types of assets classified as Level 1, which primarily represents mutual fund investments, we typically do not have any transfers between Level 1 and Level 2 measurement categories and did not have any such transfers during any period presented.
Our assessment of whether or not there were significant unobservable inputs related to fixed maturity securities was based on our observations obtained through the course of managing our investment portfolio, including interaction with other market participants, observations related to the availability and consistency of pricing and/or rating, and understanding of general market activity such as new issuance and the level of secondary market trading for a class of securities. Additionally, we considered data obtained from third-party pricing sources to determine whether our estimated values incorporate significant unobservable inputs that would result in the valuation being classified as Level 3.
The following tables present additional information about assets measured at fair value on a recurring basis and for which we have utilized significant unobservable (Level 3) inputs to determine fair value as of or for the dates indicated:

(1)	The transfers into and out of Level 3 were primarily related to private fixed rate U.S. corporate, corporate—non-U.S. and structured securities. For private fixed rate U.S. corporate securities, the transfers into and out of Level 3 resulted from a change in the observability of the additional premium to the public bond spread to adjust for the liquidity and other features of our private placements and resulted in unobservable inputs having a significant impact on certain valuations for transfers in or no longer having significant impact on certain valuations for transfers out. For structured securities, the transfers into and out of Level 3 were attributable to the changes in the observability of inputs used in the valuation as a result of liquidity or marketability of certain instruments that had a significant impact on the primary pricing source used to value the instruments.

(1)	The transfers into and out of Level 3 were primarily related to private fixed rate U.S. corporate and corporate—non-U.S. securities and structured securities. For private fixed rate U.S. corporate and corporate—non-U.S. securities, the transfers into and out of Level 3 resulted from a change in the observability of the additional premium to the public bond spread to adjust for the liquidity and other features of our private placements and resulted in unobservable inputs having a significant impact on certain valuations for transfers in or no longer having significant impact on certain valuations for transfers out. For structured securities, the transfers into and out of Level 3 were attributable to the changes in the observability of inputs used in the valuation as a result of liquidity or marketability of certain instruments that had a significant impact on the primary pricing source used to value the instruments.

Purchases, sales, issuances and settlements represent the activity that occurred during the period that results in a change of the asset or liability but does not represent changes in fair value for the instruments held at the beginning of the period. Such activity primarily consists of purchases, sales and settlements of fixed maturity, equity and trading securities and purchases, issuances and settlements of derivative instruments.
Issuances and settlements presented for policyholder account balances represent the issuances and settlements of embedded derivatives associated with our GMWB liabilities where: issuances are characterized as the change in fair value associated with the product fees recognized that are attributed to the embedded derivative to equal the expected future benefit costs upon issuance and settlements are characterized as the change in fair value upon exercising the embedded derivative instrument, effectively representing a settlement of the embedded derivative instrument. We have shown these changes in fair value separately based on the classification of this activity as effectively issuing and settling the embedded derivative instrument with all remaining changes in the fair value of these embedded derivative instruments being shown separately in the category labeled “included in net (income)” in the tables presented above.
Certain classes of instruments classified as Level 3 are excluded below as a result of not being material or due to limitations in being able to obtain the underlying inputs used by certain third-party sources, such as broker quotes, used as an input in determining fair value. The following table presents a summary of the significant unobservable inputs used for certain fair value measurements that are based on internal models and classified as Level 3 as of September 30, 2013:

Commitments and Contingencies	'
	(7) Commitments and Contingencies
	(a) Litigation
	We face the risk of litigation and regulatory investigations and actions in the ordinary course of operating our businesses, including the risk of class action lawsuits. Our pending legal and regulatory actions include proceedings specific to us and others generally applicable to business practices in the industries in which we operate. In our insurance operations, we are, have been, or may become subject to class actions and individual suits alleging, among other things, issues relating to sales or underwriting practices, increases to in-force long-term care insurance premiums, payment of contingent or other sales commissions, claims payments and procedures, product design, product disclosure, administration, additional premium charges for premiums paid on a periodic basis, denial or delay of benefits, charging excessive or impermissible fees on products, recommending unsuitable products to customers, our pricing structures and business practices in our mortgage insurance businesses, such as captive reinsurance arrangements with lenders and contract underwriting services, violations of the Real Estate Settlement and Procedures Act of 1974 (“RESPA”) or related state anti-inducement laws, and mortgage insurance policy rescissions and curtailments, and breaching fiduciary or other duties to customers, including but not limited to breach of customer information. Plaintiffs in class action and other lawsuits against us may seek very large or indeterminate amounts which may remain unknown for substantial periods of time. In our investment-related operations, we are subject to litigation involving commercial disputes with counterparties. We are also subject to litigation arising out of our general business activities such as our contractual and employment relationships. In addition, we are also subject to various regulatory inquiries, such as information requests, subpoenas, books and record examinations and market conduct and financial examinations from state, federal and international regulators and other authorities. A substantial legal liability or a significant regulatory action against us could have an adverse effect on our business, financial condition and results of operations. Moreover, even if we ultimately prevail in the litigation, regulatory action or investigation, we could suffer significant reputational harm, which could have an adverse effect on our business, financial condition or results of operations.
	As previously disclosed, in January 2012, we, along with other mortgage insurance companies, received an information request from the Consumer Financial Protection Bureau (“CFPB”) requesting information from our U.S. mortgage insurance subsidiaries with respect to reinsurance arrangements, including captive reinsurance transactions, as part of the CFPB’s review of such arrangements in the mortgage insurance industry. The CFPB further sent to us and other mortgage insurance companies a Civil Investigative Demand, dated June 20, 2012 (the “CFPB Demand”), seeking production of specified documents and responses to questions set forth in the CFPB Demand. In April 2013, Genworth Mortgage Insurance Corporation (“GEMICO”), our principal U.S. mortgage insurance subsidiary, and other mortgage insurance companies agreed to settle with the CFPB to end the agency’s review. As part of the settlement, GEMICO (and its affiliates, officers, employees and certain other related parties) are enjoined from entering into or revising certain reinsurance arrangements and violating any provisions of RESPA for a period of 10 years and GEMICO paid approximately $4 million.
	As previously disclosed, beginning in December 2011 and continuing through January 2013, one of our U.S. mortgage insurance subsidiaries was named along with several other mortgage insurance participants and mortgage lenders as a defendant in twelve putative class action lawsuits alleging that certain “captive reinsurance arrangements” were in violation of RESPA. The Barlee case was dismissed by the Court with prejudice as to our subsidiary and certain other defendants on February 27, 2013. In the Riddle case, the defendants’ motion to dismiss was denied, but the Court limited discovery at this stage to issues surrounding the statute of limitations. The Manners case was voluntarily dismissed by the plaintiffs in March 2013. In the Moriba BA case, the Court denied defendants’ motion to dismiss by order dated June 26, 2013. In the White case, plaintiffs filed a second amended complaint to address the deficiencies that the Court identified in previously dismissing the action. On July 22, 2013, our mortgage insurance subsidiary moved to dismiss the second amended complaint. In the Hill case, the defendants’ motion to dismiss was denied on June 27, 2013, but the Court limited discovery at this stage to issues surrounding the statute of limitations. In the Samp and Orange cases, the plaintiffs have appealed the dismissals to the U.S. Court of Appeals for the Ninth Circuit. The Menichino case was dismissed by the Court without prejudice as to our subsidiary and certain other defendants on July 19, 2013. In the Riddle case, on July 19, 2013, we moved for summary judgment dismissing the case. We intend to vigorously defend the remaining actions.
	As previously disclosed, in April 2012, two of our U.S. mortgage insurance subsidiaries were named as respondents in two arbitrations, one brought by Bank of America, N.A. and one brought by Countrywide Home Loans, Inc. and Bank of America, N.A. as claimants. Claimants allege breach of contract and breach of the covenant of good faith and fair dealing, and seek a declaratory judgment relating to our subsidiaries’ mortgage insurance claims handling practices in connection with denying, curtailing or rescinding coverage of mortgage insurance. Claimants and our subsidiaries are engaged in settlement negotiations regarding a potential resolution of certain, and potentially all, aspects of the disputes. We currently believe we may be able to resolve this matter for significantly less than $834 million, the previously-disclosed amount of claimed damages in this matter.
	At this time, we cannot determine or predict the ultimate outcome of any of the pending legal and regulatory matters specifically identified above or the likelihood of potential future legal and regulatory matters against us. In light of the inherent uncertainties involved in these matters, no amounts have been accrued. We also are not able to provide an estimate or range of possible losses related to these matters.
	(b) Commitments
	As of September 30, 2013, we were committed to fund $67 million in limited partnership investments, $58 million in U.S. commercial mortgage loans and $8 million in private placement investments.

	During 2013, Genworth Holdings repurchased $15 million aggregate principal amount of the 5.75% senior notes that mature in 2014, plus accrued and unpaid interest. In June 2013, Genworth Holdings repurchased $4 million aggregate principal amount of the 4.95% senior notes that mature in 2015 (the “2015 Notes”), plus accrued and unpaid interest.
	In August 2013, Genworth Holdings issued $400 million aggregate principal amount of senior notes, with an interest rate of 4.90% per year payable semi-annually, and maturing in 2023 (“2023 Notes”). The 2023 Notes are Genworth Holdings’ direct, unsecured obligations and will rank equally in right of payment with all of its existing and future unsecured and unsubordinated obligations. The 2023 Notes are fully and unconditionally guaranteed on an unsecured and unsubordinated basis by New Genworth. The net proceeds of $395 million from the issuance of the 2023 Notes, together with cash on hand at Genworth Holdings, were used to redeem all $346 million of the remaining outstanding aggregate principal amount of Genworth Holdings’ 2015 Notes, plus accrued and unpaid interest on such notes, and a pre-tax make-whole expense of approximately $30 million.

Segment Information	'
	(9) Segment Information
	We currently operate through three divisions: U.S. Life Insurance, Global Mortgage Insurance and Corporate and Other. Under these divisions, there are five operating business segments. The U.S. Life Insurance Division includes the U.S. Life Insurance segment. The Global Mortgage Insurance Division includes the International Mortgage Insurance and U.S. Mortgage Insurance segments. The Corporate and Other Division includes the International Protection and Runoff segments and Corporate and Other activities. Our operating business segments are as follows: (1) U.S. Life Insurance, which includes our life insurance, long-term care insurance and fixed annuities businesses; (2) International Mortgage Insurance, which includes mortgage insurance-related products and services; (3) U.S. Mortgage Insurance, which includes mortgage insurance-related products and services; (4) International Protection Insurance, which includes our lifestyle protection insurance business; and (5) Runoff, which includes the results of non-strategic products which are no longer actively sold. Our non-strategic products primarily include our variable annuity, variable life insurance, institutional, corporate-owned life insurance and other accident and health insurance products. Institutional products consist of: funding agreements, FABNs and GICs.
	We also have Corporate and Other activities which include debt financing expenses that are incurred at the Genworth Holdings holding company level, unallocated corporate income and expenses, eliminations of inter-segment transactions and the results of other businesses that are managed outside of our operating segments. Effective April 1, 2013 (immediately prior to the holding company reorganization), Genworth Holdings completed the sale of its reverse mortgage business (which had been part of Corporate and Other activities) for total proceeds of $22 million. The gain on the sale was not significant.
	We use the same accounting policies and procedures to measure segment income (loss) and assets as our consolidated net income (loss) and assets. Our chief operating decision maker evaluates segment performance and allocates resources on the basis of “net operating income (loss).” We define net operating income (loss) as income (loss) from continuing operations excluding the after-tax effects of income attributable to noncontrolling interests, net investment gains (losses), goodwill impairments, gains (losses) on the sale of businesses and infrequent or unusual non-operating items. We exclude net investment gains (losses) and infrequent or unusual non-operating items because we do not consider them to be related to the operating performance of our segments and Corporate and Other activities. A component of our net investment gains (losses) is the result of impairments, the size and timing of which can vary significantly depending on market credit cycles. In addition, the size and timing of other investment gains (losses) can be subject to our discretion and are influenced by market opportunities, as well as asset-liability matching considerations. Goodwill impairments and gains (losses) on the sale of businesses are also excluded from net operating income (loss) because, in our opinion, they are not indicative of overall operating trends. Other non-operating items are also excluded from net operating income (loss) if, in our opinion, they are not indicative of overall operating trends.
	There were no infrequent or unusual items excluded from net operating income (loss) during the periods presented other than a $13 million after-tax expense recorded in the second quarter of 2013 related to restructuring costs. In June 2013, we announced an expense reduction plan as we continue to work on improving the operating performance of our businesses resulting in a pre-tax non-operating charge of $20 million reflecting severance, outplacement and other associated costs. This plan eliminated approximately 400 positions, including 150 open positions that will not be filled, and will reduce related information technology and program spend.
	While some of these items may be significant components of net income (loss) available to Genworth Financial, Inc.’s common stockholders in accordance with U.S. GAAP, we believe that net operating income (loss), and measures that are derived from or incorporate net operating income (loss), are appropriate measures that are useful to investors because they identify the income (loss) attributable to the ongoing operations of the business. Management also uses net operating income (loss) as a basis for determining awards and compensation for senior management and to evaluate performance on a basis comparable to that used by analysts. However, the items excluded from net operating income (loss) have occurred in the past and could, and in some cases will, recur in the future. Net operating income (loss) is not a substitute for net income (loss) available to Genworth Financial, Inc.’s common stockholders determined in accordance with U.S. GAAP. In addition, our definition of net operating income (loss) may differ from the definitions used by other companies.

	During the three months ended March 31, 2013, in connection with the agreement to sell the wealth management business, we recognized a goodwill impairment of $13 million as a result of the carrying value for the business exceeding fair value. Additionally, we agreed to settle our contingent consideration liability related to our purchase of Altegris Capital, LLC in 2010 for approximately $40 million, which resulted in a loss of approximately $5 million from the change in fair value of this liability. In accordance with the accounting guidance for groups of assets that are held-for-sale, we recorded an additional loss of approximately $9 million to record the carrying value of the business at its fair value less costs to sell. During the three months ended September 30, 2013, we recognized an additional after-tax loss on the sale of $2 million at closing, which was based on carrying value and working capital at close, as well as expenses associated with the sale.

Our insurance company subsidiaries are restricted by state and foreign laws and regulations as to the amount of dividends they may pay to their parent without regulatory approval in any year, the purpose of which is to protect affected insurance policyholders, depositors and investors. Any dividends in excess of limits are deemed “extraordinary” and require approval. Based on estimated statutory results as of December 31, 2012, in accordance with applicable dividend restrictions, our subsidiaries could pay dividends of approximately $1.1 billion to us in 2013 without obtaining regulatory approval, and the remaining net assets are considered restricted. While the $1.1 billion is unrestricted, we do not expect our insurance subsidiaries to pay dividends to us in 2013 at this level as they retain capital for growth and to meet capital requirements and desired thresholds. As of December 31, 2012, Genworth Financial’s and Genworth Holdings’ subsidiaries had restricted net assets of $15.4 billion and $16.7 billion, respectively.

	(1)	The transfers into and out of Level 3 were primarily related to private fixed rate U.S. corporate, corporate—non-U.S. and structured securities. For private fixed rate U.S. corporate securities, the transfers into and out of Level 3 resulted from a change in the observability of the additional premium to the public bond spread to adjust for the liquidity and other features of our private placements and resulted in unobservable inputs having a significant impact on certain valuations for transfers in or no longer having significant impact on certain valuations for transfers out. For structured securities, the transfers into and out of Level 3 were attributable to the changes in the observability of inputs used in the valuation as a result of liquidity or marketability of certain instruments that had a significant impact on the primary pricing source used to value the instruments.

(1)	The transfers into and out of Level 3 were primarily related to private fixed rate U.S. corporate and corporate—non-U.S. securities and structured securities. For private fixed rate U.S. corporate and corporate—non-U.S. securities, the transfers into and out of Level 3 resulted from a change in the observability of the additional premium to the public bond spread to adjust for the liquidity and other features of our private placements and resulted in unobservable inputs having a significant impact on certain valuations for transfers in or no longer having significant impact on certain valuations for transfers out. For structured securities, the transfers into and out of Level 3 were attributable to the changes in the observability of inputs used in the valuation as a result of liquidity or marketability of certain instruments that had a significant impact on the primary pricing source used to value the instruments.

[1]	Represents contingent receivables associated with recent business dispositions.
[2]	Represents embedded derivatives associated with the reinsured portion of our GMWB liabilities.
[3]	The transfers into and out of Level 3 were primarily related to private fixed rate U.S. corporate, corporate-non-U.S. and structured securities. For private fixed rate U.S. corporate securities, the transfers into and out of Level 3 resulted from a change in the observability of the additional premium to the public bond spread to adjust for the liquidity and other features of our private placements and resulted in unobservable inputs having a significant impact on certain valuations for transfers in or no longer having significant impact on certain valuations for transfers out. For structured securities, the transfers into and out of Level 3 were attributable to the changes in the observability of inputs used in the valuation as a result of liquidity or marketability of certain instruments that had a significant impact on the primary pricing source used to value the instruments.

During the second quarter of 2012, we began classifying private securities without an external rating as Level 3, which resulted in a significant number of securities being transferred into Level 3.
