Formation of Genworth and Basis

Formation of Genworth and Basis of Presentation	6 Months Ended
	Jun. 30, 2017
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 in 2003 in preparation for an initial public offering (“IPO”) of Genworth’s common stock, which was completed on May 28, 2004. 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 that it had formed. The new public holding company was incorporated in Delaware on December 5, 2012, in connection with the reorganization, and was renamed Genworth Financial, Inc. (“Genworth Financial”) upon the completion of the reorganization. On October 21, 2016, Genworth Financial entered into an agreement and plan of merger (the “Merger Agreement”) with Asia Pacific Global Capital Co., Ltd. (“the Parent”), a limited liability company incorporated in the People’s Republic of China, and Asia Pacific Global Capital USA Corporation (“Merger Sub”), a Delaware corporation and an indirect, wholly-owned subsidiary of the Parent. Subject to the terms and conditions of the Merger Agreement, including the satisfaction or waiver of certain conditions, Merger Sub would merge with and into Genworth Financial with Genworth Financial surviving the merger as an indirect, wholly-owned subsidiary of the Parent. The Parent is a newly formed subsidiary of China Oceanwide Holdings Group Co., Ltd. (together with its affiliates, “China Oceanwide”). China Oceanwide has agreed to acquire all of our outstanding common stock for a total transaction value of approximately $2.7 billion, or $5.43 per share in cash. At a special meeting held on March 7, 2017, Genworth’s stockholders voted on and approved a proposal to adopt the Merger Agreement. The transaction remains subject to closing conditions, including the receipt of required regulatory approvals in the U.S., China, and other international jurisdictions. Both parties are engaging with the relevant regulators regarding the applications and the pending transaction. The accompanying unaudited condensed financial statements include on a consolidated basis the accounts of Genworth Financial and the affiliate companies in which it holds a majority voting interest or where it is the primary beneficiary of a variable interest entity (“VIE”). All intercompany accounts and transactions have been eliminated in consolidation. References to “Genworth,” the “Company,” “we” or “our” in the accompanying unaudited condensed consolidated financial statements and these notes thereto are, unless the context otherwise requires, to Genworth Financial on a consolidated basis. We operate our business through the following five operating segments: • U.S. Mortgage Insurance. • Canada Mortgage Insurance. • Australia Mortgage Insurance. • U.S. Life Insurance. • Runoff. In addition to our five operating business segments, we also have Corporate and Other activities which include debt financing expenses that are incurred at the Genworth Holdings 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, including certain smaller international mortgage insurance businesses and 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 unaudited 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 unaudited condensed consolidated financial statements should not be regarded as necessarily indicative of results that may be expected for the entire year. The unaudited condensed consolidated financial statements included herein should be read in conjunction with the audited consolidated financial statements and related notes contained in our 2016 Annual Report on Form 10-K. Certain prior year amounts have been reclassified to conform to the current year presentation.

Accounting Changes

Accounting Changes	6 Months Ended
	Jun. 30, 2017
Accounting Changes	(2) Accounting Changes Accounting Pronouncements Recently Adopted On January 1, 2017, we adopted new accounting guidance related to the accounting for stock compensation. The guidance primarily simplifies the accounting for employee share-based payment transactions, including a new requirement to record all of the income tax effects at settlement or expiration through the income statement, classifications of awards as either equity or liabilities, and classification on the statement of cash flows. We adopted this new accounting guidance on a modified retrospective basis and recorded a previously disallowed deferred tax asset of $9 million with a corresponding increase to cumulative effect of change in accounting within retained earnings at adoption. On January 1, 2017, we adopted new accounting guidance related to transition to the equity method of accounting. The guidance eliminates the retrospective application of the equity method of accounting when obtaining significant influence over a previously held investment. The guidance requires that an entity that has an available-for-sale equity security that becomes qualified for the equity method of accounting recognize through earnings the unrealized holding gain or loss in accumulated other comprehensive income at the date the investment becomes qualified for use of the equity method. We did not have any significant impact from this guidance on our consolidated financial statements. On January 1, 2017, we adopted new accounting guidance related to the assessment of contingent put and call options in debt instruments. The guidance clarifies the requirements for assessing whether contingent call (put) options that can accelerate the payment of principal on debt instruments are clearly and closely related to their debt hosts. An entity performing the assessment under the amendments in this update is required to assess the embedded call (put) options solely in accordance with the four-step decision sequence. This guidance is consistent with our previous accounting practices and, accordingly, did not have any impact on our consolidated financial statements. On January 1, 2017, we adopted new accounting guidance related to the effect of derivative contract novations on existing hedge accounting relationships. The guidance clarifies that a change in the counterparty to a derivative instrument that has been designated as the hedging instrument does not, in and of itself, require dedesignation of that hedging relationship provided that all other hedge accounting criteria continue to be met. This guidance is consistent with our previous accounting for derivative contract novations and, accordingly, did not have any impact on our consolidated financial statements. Accounting Pronouncements Not Yet Adopted In May 2017, the Financial Accounting Standards Board (“the FASB”) issued new guidance to clarify when to account for a change to share-based compensation as a modification. The new guidance requires modification accounting only if there are changes to the fair value, vesting conditions or classification, as a liability or equity, of the share-based compensation. The guidance is effective, prospectively, for us on January 1, 2018, accordingly, the guidance will not have any impact at adoption. In March 2017, the FASB issued new guidance shortening the amortization period for the premium component of callable debt securities purchased at a premium. The guidance requires the premium to be amortized to the earliest call date. This change does not apply to securities held at a discount. The guidance is currently effective for us on January 1, 2019, with early adoption permitted. We are in process of evaluating the impact the guidance may have on our consolidated financial statements. In February 2017, the FASB issued new guidance to clarify the accounting for gains and losses from the derecognition of nonfinancial assets and accounting for partial sales of nonfinancial assets. The new guidance clarifies when transferring ownership interests in a consolidated subsidiary holding nonfinancial assets is within scope. It also states that the reporting entity should identify each distinct nonfinancial asset and derecognize when a counterparty obtains control, and clarifies the accounting for partial sales. The new guidance is currently effective for us on January 1, 2018. We do not expect any significant impacts from this guidance on our consolidated financial statements. In January 2017, the FASB issued new guidance simplifying the test for goodwill impairment. The new guidance states goodwill impairment is equal to the difference between the carrying value and fair value of the reporting unit up to the amount of recorded goodwill. The new guidance is currently effective for us on January 1, 2020, with early adoption permitted for testing dates after January 1, 2017. We do not expect any significant impacts from this new guidance on our consolidated financial statements. In October 2016, the FASB issued new guidance related to the income tax effects of intra-entity transfers of assets other than inventory. The new guidance states that an entity should recognize the income tax consequences of an intra-entity transfer of an asset other than inventory when the transfer occurs. The guidance is currently effective for us on January 1, 2018. We are still in process of evaluating the impact the guidance may have on our consolidated financial statements, including any cumulative effect adjustment that will be recorded directly to retained earnings as of the beginning of the period of adoption.

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.

than 12 months were investment grade and less than 20% below cost. These unrealized losses were primarily attributable to increased market volatility, mostly concentrated in our corporate securities. For securities that have been in a continuous unrealized loss position for less than 12 months, the average fair value percentage below cost was approximately 2% as of June 30, 2017. Fixed Maturity Securities In A Continuous Unrealized Loss Position For 12 Months Or More Of the $61 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 78% of the unrealized losses were related to investment grade securities as of June 30, 2017. These unrealized losses were predominantly attributable to corporate securities including variable rate securities purchased in a higher rate and lower spread environment. The average fair value percentage below cost for these securities was approximately 5% as of June 30, 2017. See below for additional discussion related to fixed maturity securities that have been in a continuous unrealized 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 unrealized loss position for 12 months or more by asset class as of June 30, 2017: Investment Grade 20% to 50% Greater than 50% (Dollar amounts in millions) Fair Gross % of total Number of Fair Gross % of total Number of Fixed maturity securities: State and political subdivisions $ 10 $ (2 ) 1 % 1 $ — $ — — % — Total $ 10 $ (2 ) 1 % 1 $ — $ — — % — Below Investment Grade 20% to 50% Greater than 50% (Dollar amounts in millions) Fair Gross % of total Number of Fair Gross % of total Number of Fixed maturity securities: Non-U.S. corporate: Energy 3 (1 ) — 1 — — — — Other 3 (1 ) — 1 — — — — Total non-U.S. corporate 6 (2 ) — 2 — — — — Total $ 6 $ (2 ) — % 2 $ — $ — — % — For all securities in an unrealized loss position, we expect to recover the amortized cost based on our estimate of the amount and timing of cash flows to be collected. We do not intend to sell nor do we expect that we will be required to sell these securities prior to recovering our amortized cost. See below for further discussion of gross unrealized losses by asset class. State and political subdivisions As indicated above, $2 million of gross unrealized losses were related to a state and political subdivision fixed maturity security that has been in a continuous loss position for more than 12 months and was more than 20% below cost. The unrealized loss for this security was 21% below cost, primarily related to widening of credit spreads since acquisition as a result of higher risk premiums being attributed to this security from uncertainty related to special revenues supporting this type of obligation as well as certain securities having longer duration that may be viewed as less desirable in the current market place. Additionally, the fair value of this security class has been negatively impacted as a result of having certain bond insurers associated with the security. In our analysis of impairment for this security, we expect to recover our amortized cost from the cash flows of the underlying security before any guarantee support. However, the existence of these guarantees may negatively impact the value of the debt security in certain instances. We performed an analysis of this security and the underlying activities that are expected to support the cash flows and determined we expect to recover our amortized cost. Non-U.S. corporate As indicated above, $2 million of gross unrealized losses were related to non-U.S. corporate fixed maturity securities that have been in an unrealized loss position for more than 12 months and were more than 20% below cost. Of the total unrealized losses for non-U.S. corporate fixed maturity securities, all were below investment grade and not concentrated in any one sector. We expect that our investments in non-U.S. 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 reasonably possible that issuers of our investments in non-U.S. corporate securities may perform worse than current expectations. Such events may lead us to recognize write-downs within our portfolio of non-U.S. corporate securities in the future.

As of June 30, 2017, securities issued by finance and insurance, utilities and consumer—non-cyclical industry groups represented approximately 23%, 14% and 14%, respectively, of our domestic and foreign corporate fixed maturity securities portfolio. No other industry group comprised more than 10% of our investment portfolio. As of June 30, 2017, 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 principal payments, amortization and allowance for loan losses. We diversify our commercial mortgage loans by both property type and geographic region. The following tables set forth the distribution across property type and geographic region for commercial mortgage loans as of the dates indicated: June 30, 2017 December 31, 2016 (Amounts in millions) Carrying % of Carrying % of Property type: Retail $ 2,199 35 % $ 2,178 36 % Industrial 1,590 25 1,533 25 Office 1,480 24 1,430 23 Apartments 470 8 455 7 Mixed use 234 4 245 4 Other 277 4 284 5 Subtotal 6,250 100 % 6,125 100 % Unamortized balance of loan origination fees and costs (3 ) (2 ) Allowance for losses (10 ) (12 ) Total $ 6,237 $ 6,111 June 30, 2017 December 31, 2016 (Amounts in millions) Carrying % of Carrying % of Geographic region: South Atlantic $ 1,608 26 % $ 1,546 25 % Pacific 1,603 26 1,567 27 Middle Atlantic 908 14 915 15 Mountain 547 9 554 9 West North Central 442 7 435 7 East North Central 383 6 388 6 West South Central 318 5 311 5 New England 233 4 206 3 East South Central 208 3 203 3 Subtotal 6,250 100 % 6,125 100 % Unamortized balance of loan origination fees and costs (3 ) (2 ) Allowance for losses (10 ) (12 ) Total $ 6,237 $ 6,111 The following tables set forth the aging of past due commercial mortgage loans by property type as of the dates indicated: June 30, 2017 (Amounts in millions) 31 - 60 days 61 - 90 days Greater than past due Total Current Total Property type: Retail $ — $ — $ — $ — $ 2,199 $ 2,199 Industrial — — — — 1,590 1,590 Office — — — — 1,480 1,480 Apartments — — — — 470 470 Mixed use — — — — 234 234 Other — — — — 277 277 Total recorded investment $ — $ — $ — $ — $ 6,250 $ 6,250 % of total commercial mortgage loans — % — % — % — % 100 % 100 % December 31, 2016 (Amounts in millions) 31 - 60 days 61 - 90 days Greater than 90 days past due Total Current Total Property type: Retail $ — $ — $ — $ — $ 2,178 $ 2,178 Industrial 1 — 12 13 1,520 1,533 Office — — — — 1,430 1,430 Apartments — — — — 455 455 Mixed use — — — — 245 245 Other — — — — 284 284 Total recorded investment $ 1 $ — $ 12 $ 13 $ 6,112 $ 6,125 % of total commercial mortgage loans — % — % — % — % 100 % 100 % As of June 30, 2017 and December 31, 2016, we had no commercial mortgage loans that were past due for more than 90 days and still accruing interest. We also did not have any commercial mortgage loans that were past due for less than 90 days on non-accrual status as of June 30, 2017 and December 31, 2016. We evaluate the impairment of commercial mortgage loans on an individual loan basis. As of June 30, 2017, none of our commercial mortgage loans were greater than 90 days past due. During the six months ended June 30, 2017 and the year ended December 31, 2016, we modified or extended 5 and 16 commercial mortgage loans, respectively, with a total carrying value of $8 million and $85 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, except during the year ended December 31, 2016, one loan with a carrying value $1 million at the time of modification was considered a troubled debt restructuring. This loan was sold in the fourth quarter of 2016. The following table sets forth the allowance for credit losses and recorded investment in commercial mortgage loans as of or for the periods indicated: Three months ended Six months ended (Amounts in millions) 2017 2016 2017 2016 Allowance for credit losses: Beginning balance $ 11 $ 15 $ 12 $ 15 Charge-offs — (4 ) — (4 ) Recoveries — — — — Provision (1 ) 2 (2 ) 2 Ending balance $ 10 $ 13 $ 10 $ 13 Ending allowance for individually impaired loans $ — $ — $ — $ — Ending allowance for loans not individually impaired that were evaluated collectively for impairment $ 10 $ 13 $ 10 $ 13 Recorded investment: Ending balance $ 6,250 $ 6,136 $ 6,250 $ 6,136 Ending balance of individually impaired loans $ — $ 23 $ — $ 23 Ending balance of loans not individually impaired that were evaluated collectively for impairment $ 6,250 $ 6,113 $ 6,250 $ 6,113 As of June 30, 2017, we had no individually impaired commercial mortgage loans. As of June 30, 2016, we had an individually impaired commercial mortgage loan included within the office property type with a recorded investment of $5 million, an unpaid principal balance of $6 million and charge-offs of $1 million, an individually impaired commercial mortgage loan included within the retail property type with a recorded investment of $5 million, an unpaid principal balance of $6 million and charge-offs of $1 million, and an individually impaired loan within the industrial property type had a recorded investment of $13 million, an unpaid principal balance of $16 million and total charge-offs of $3 million. As of December 31, 2016, we had one individually impaired loan within the industrial property type with a recorded investment of $12 million, an unpaid principal balance of $15 million and charge-offs of $3 million. 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 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.

Derivative Instruments

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. The following table sets forth our positions in derivative instruments as of the dates indicated: Derivative assets Derivative liabilities Fair value Fair value (Amounts in millions) Balance sheet classification June 30, December 31, Balance sheet classification June 30, December 31, Derivatives designated as hedges Cash flow hedges: Interest rate swaps Other invested assets $ 243 $ 237 Other liabilities $ 182 $ 203 Foreign currency swaps Other invested assets 2 4 Other liabilities — — Total cash flow hedges 245 241 182 203 Total derivatives designated as hedges 245 241 182 203 Derivatives not designated as hedges Interest rate swaps Other invested assets 347 359 Other liabilities 150 146 Foreign currency swaps Other invested assets 3 — Other liabilities 2 5 Credit default swaps related to securitization entities Restricted other invested assets — — Other liabilities — 1 Equity index options Other invested assets 81 72 Other liabilities — — Financial futures Other invested assets — — Other liabilities — — Equity return swaps Other invested assets 2 1 Other liabilities 7 1 Other foreign currency contracts Other invested assets 65 35 Other liabilities 26 27 GMWB embedded derivatives Reinsurance recoverable (1) 15 16 Policyholder account balances (2) 281 303 Fixed index annuity embedded derivatives Other assets — — Policyholder account balances (3) 376 344 Indexed universal life embedded derivatives Reinsurance recoverable — — Policyholder account balances (4) 13 11 Total derivatives not designated as hedges 513 483 855 838 Total derivatives $ 758 $ 724 $ 1,037 $ 1,041 (1) Represents embedded derivatives associated with the reinsured portion of our guaranteed minimum withdrawal benefits (“GMWB”) liabilities. (2) Represents the embedded derivatives associated with our GMWB liabilities, excluding the impact of reinsurance. (3) Represents the embedded derivatives associated with our fixed index annuity liabilities. (4) Represents the embedded derivatives associated with our indexed universal life liabilities. The fair value of derivative positions presented above was not offset by the respective collateral amounts retained or provided under these agreements. The activity associated with derivative instruments can generally be measured by the change in notional value over the periods presented. However, for GMWB, fixed index annuity embedded derivatives and indexed universal life embedded derivatives, the change between periods is best illustrated by the number of policies. The following tables represent activity associated with derivative instruments as of the dates indicated: (Notional in millions) Measurement December 31, Additions Maturities/ June 30, Derivatives designated as hedges Cash flow hedges: Interest rate swaps Notional $ 11,570 $ — $ (215 ) $ 11,355 Foreign currency swaps Notional 22 — — 22 Total cash flow hedges 11,592 — (215 ) 11,377 Total derivatives designated as hedges 11,592 — (215 ) 11,377 Derivatives not designated as hedges Interest rate swaps Notional 4,679 — — 4,679 Foreign currency swaps Notional 201 73 (4 ) 270 Credit default swaps Notional 39 — — 39 Credit default swaps related to securitization entities Notional 312 — (100 ) 212 Equity index options Notional 2,396 951 (837 ) 2,510 Financial futures Notional 1,398 2,908 (2,960 ) 1,346 Equity return swaps Notional 165 108 (153 ) 120 Other foreign currency contracts Notional 3,130 1,760 (453 ) 4,437 Total derivatives not designated as hedges 12,320 5,800 (4,507 ) 13,613 Total derivatives $ 23,912 $ 5,800 $ (4,722 ) $ 24,990 (Number of policies) Measurement December 31, Additions Maturities/ June 30, Derivatives not designated as hedges GMWB embedded derivatives Policies 33,238 — (1,498 ) 31,740 Fixed index annuity embedded derivatives Policies 17,549 — (248 ) 17,301 Indexed universal life embedded derivatives Policies 1,074 1 (40 ) 1,035 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 tables provide a reconciliation of current period changes, net of applicable income taxes, for these designated derivatives presented in the separate component of stockholders’ equity labeled “derivatives qualifying as hedges,” for the periods indicated: Three months ended June 30, (Amounts in millions) 2017 2016 Derivatives qualifying as effective accounting hedges as of April 1 $ 2,036 $ 2,302 Current period increases (decreases) in fair value, net of deferred taxes of $(27) and $(86) 48 160 Reclassification to net (income), net of deferred taxes of $12 and $12 (20 ) (23 ) Derivatives qualifying as effective accounting hedges as of June 30 $ 2,064 $ 2,439 Six months ended (Amounts in millions) 2017 2016 Derivatives qualifying as effective accounting hedges as of January 1 $ 2,085 $ 2,045 Current period increases (decreases) in fair value, net of deferred taxes of $(11) and $(233) 19 435 Reclassification to net (income), net of deferred taxes of $23 and $22 (40 ) (41 ) Derivatives qualifying as effective accounting hedges as of June 30 $ 2,064 $ 2,439 The total of derivatives designated as cash flow hedges of $2,064 million, net of taxes, recorded in stockholders’ equity as of June 30, 2017 is expected to be reclassified to net income in the future, 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, $91 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 2057. During the six months ended June 30, 2017, there was approximately $1 million reclassified to net income in connection with forecasted transactions that were no longer considered probable of occurring. 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, fixed index annuities and indexed universal life; (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 swaps, options and forward contracts to mitigate currency risk associated with non-functional currency investments held by certain foreign subsidiaries and future dividends or 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 and indexed universal life 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. The following tables provide the pre-tax gain (loss) recognized in net income for the effects of derivatives not designated as hedges for the periods indicated: Three months ended June 30, Classification of gain (loss) recognized in net income (Amounts in millions) 2017 2016 Interest rate swaps $ (1 ) $ (7 ) Net investment gains (losses) Interest rate swaps related to securitization entities — (5 ) Net investment gains (losses) Credit default swaps — 1 Net investment gains (losses) Credit default swaps related to securitization entities 2 5 Net investment gains (losses) Equity index options 13 (1 ) Net investment gains (losses) Financial futures 9 19 Net investment gains (losses) Equity return swaps (6 ) 5 Net investment gains (losses) Other foreign currency contracts 31 (2 ) Net investment gains (losses) Foreign currency swaps 2 (3 ) Net investment gains (losses) GMWB embedded derivatives 1 (40 ) Net investment gains (losses) Fixed index annuity embedded derivatives (16 ) (9 ) Net investment gains (losses) Indexed universal life embedded derivatives 2 1 Net investment gains (losses) Total derivatives not designated as hedges $ 37 $ (36 ) Six months June 30, Classification of gain (loss) recognized in net income (Amounts in millions) 2017 2016 Interest rate swaps $ 1 $ 8 Net investment gains (losses) Interest rate swaps related to securitization entities — (10 ) Net investment gains (losses) Credit default swaps related to securitization entities 4 14 Net investment gains (losses) Equity index options 26 (4 ) Net investment gains (losses) Financial futures (8 ) 26 Net investment gains (losses) Equity return swaps (14 ) 7 Net investment gains (losses) Other foreign currency contracts 26 (4 ) Net investment gains (losses) Foreign currency swaps 5 7 Net investment gains (losses) GMWB embedded derivatives 34 (118 ) Net investment gains (losses) Fixed index annuity embedded derivatives (36 ) (6 ) Net investment gains (losses) Indexed universal life embedded derivatives 3 3 Net investment gains (losses) Total derivatives not designated as hedges $ 41 $ (77 ) Derivative Counterparty Credit Risk Most of our derivative arrangements require the posting of collateral by the counterparty 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 table presents additional information about derivative assets and liabilities subject to an enforceable master netting arrangement as of the dates indicated: June 30, 2017 December 31, 2016 (Amounts in millions) Derivatives (1) Derivatives (2) Net Derivatives (1) Derivatives (2) Net Amounts presented in the balance sheet: Gross amounts recognized $ 757 $ 373 $ 384 $ 724 $ 387 $ 337 Gross amounts offset in the balance sheet — — — — — — Net amounts presented in the balance sheet 757 373 384 724 387 337 Gross amounts not offset in the balance sheet: Financial instruments (3) (253 ) (253 ) — (172 ) (172 ) — Collateral received (425 ) — (425 ) (467 ) — (467 ) Collateral pledged — (373 ) 373 — (557 ) 557 Over collateralization 8 255 (247 ) 1 344 (343 ) Net amount $ 87 $ 2 $ 85 $ 86 $ 2 $ 84 (1) Included $14 million and $16 million of accruals on derivatives classified as other assets and does not include amounts related to embedded derivatives as of June 30, 2017 and December 31, 2016, respectively. (2) Included $6 million and $5 million of accruals on derivatives classified as other liabilities and does not include amounts related to embedded derivatives and derivatives related to securitization entities as of June 30, 2017 and December 31, 2016, respectively. (3) Amounts represent derivative assets and/or liabilities that are presented gross within the balance sheet but are held with the same counterparty where we have a master netting arrangement. This adjustment results in presenting the net asset and net liability position for each counterparty. 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 downgrade provisions had been triggered as a result of downgrades of our counterparties, we could have claimed up to $87 million and $86 million as of June 30, 2017 and December 31, 2016, respectively, or have been required to disburse up to $2 million as of June 30, 2017 and December 31, 2016. The chart above excludes 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 Instruments	(6) Fair Value of Financial Instruments Assets and liabilities that are reflected in the accompanying unaudited condensed 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. Restricted commercial mortgage loans. Other invested assets. Long-term borrowings. Non-recourse funding obligations. Borrowings related to securitization entities. Investment contracts. The following represents our estimated fair value of financial assets and liabilities that are not required to be carried at fair value as of the dates indicated: June 30, 2017 Notional amount Carrying amount Fair value (Amounts in millions) Total Level 1 Level 2 Level 3 Assets: Commercial mortgage loans $ (1) $ 6,237 $ 6,533 $ — $ — $ 6,533 Restricted commercial mortgage loans (1) 118 130 — — 130 Other invested assets (1) 1,101 1,123 — 946 177 Liabilities: Long-term borrowings (1) 4,205 3,626 — 3,471 155 Non-recourse funding obligations (1) 310 195 — — 195 Borrowings related to securitization entities (1) 51 53 — 53 — Investment contracts (1) 15,667 16,212 — 5 16,207 Other firm commitments: Commitments to fund limited partnerships 268 — — — — — Ordinary course of business lending commitments 59 — — — — — December 31, 2016 Notional amount Carrying amount Fair value (Amounts in millions) Total Level 1 Level 2 Level 3 Assets: Commercial mortgage loans $ (1) $ 6,111 $ 6,247 $ — $ — $ 6,247 Restricted commercial mortgage loans (1) 129 141 — — 141 Other invested assets (1) 459 473 — 352 121 Liabilities: Long-term borrowings (1) 4,180 3,582 — 3,440 142 Non-recourse funding obligations (1) 310 186 — — 186 Borrowings related to securitization entities (1) 62 65 — 65 — Investment contracts (1) 16,437 16,993 — 5 16,988 Other firm commitments: Commitments to fund limited partnerships 201 — — — — — Ordinary course of business lending commitments 73 — — — — — (1) These financial instruments do not have notional amounts. 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 fair value of fixed maturity, equity and trading securities are estimated primarily based on information derived from third-party pricing services (“pricing services”), internal models and/or broker quotes, which use a market approach, income approach or a combination of the market and income approach depending on the type of instrument and availability of information. In general, a market approach is utilized if there is readily available and relevant market activity for an individual security. In certain cases where market information is not available for a specific security but is available for similar securities, a security is valued using that market information for similar securities, which is also a market approach. When market information is not available for a specific security or is available but such information is less relevant or reliable, an income approach or a combination of a market and income approach is utilized. For securities with optionality, such as call or prepayment features (including mortgage-backed or asset-backed securities), an income approach may be used. In addition, a combination of the results from market and income approaches may be used to estimate fair value. These valuation techniques may change from period to period, based on the relevance and availability of market data. We utilize certain third-party data providers when determining fair value. We consider information obtained from pricing services as well as 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 to be of high quality, 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 evaluate changes in fair value that are greater than certain pre-defined thresholds 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. A pricing committee provides additional oversight and guidance in the evaluation and review of the pricing methodologies used to value our investment portfolio. 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 public or private fixed maturity securities. In certain instances, we utilize price caps for broker quoted securities where the estimated market yield results in a valuation that may exceed the amount that we believe would be received in a market transaction. 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. Additionally, on a monthly basis we review a sample of securities, examining the pricing service’s assumptions to determine if we agree with the service’s derived price. When available, we also evaluate the prices sampled as compared to other public prices. If a variance greater than a pre-defined threshold is noted, additional review of the price is executed to ensure accuracy. 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 income approach where we obtain public bond spreads and utilize those in an internal model to determine fair value. Other inputs to the model include rating and weighted-average life, as well as sector which is used to assign the spread. 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. 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 and value all private fixed maturity securities at par that have less than 12 months to maturity. When a security does not have an external rating, we assign the security an internal rating to determine the appropriate public bond spread that should be utilized in the valuation. To evaluate the reasonableness of the internal model, we review a sample of private fixed maturity securities each month. In that review we compare the modeled prices to the prices of similar public securities in conjunction with analysis on current market indicators. If a pricing variance greater than a pre-defined threshold is noted, additional review of the price is executed to ensure accuracy. At the end of each month, all internally modeled prices are compared to the prior month prices with an evaluation of all securities with a month-over-month change greater than a pre-defined threshold. 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, liquidity premiums applied, and whether external ratings are available for our private placements to determine whether the spreads utilized would be considered observable inputs. We classify private securities without an external rating and public bond spread as Level 3. In general, increases (decreases) in credit spreads will decrease (increase) the fair value for our fixed maturity securities. For broker quotes, we consider the valuation methodology utilized by the third party and analyze a sample each month to assess reasonableness given then-current market conditions. Additionally, for broker quotes on certain structured securities, we validate prices received against other publicly available pricing sources. Broker quotes are typically based on an income approach given the lack of available market data. As the valuation typically includes significant unobservable inputs, 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 determine fair value using an income approach. We analyze a sample each month to assess reasonableness given then-current market conditions. 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. A summary of the inputs used for our fixed maturity, equity and trading securities based on the level in which instruments are classified is included below. We have combined certain classes of instruments together as the nature of the inputs is similar. Level 1 measurements Equity securities. 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. Level 2 measurements Fixed maturity securities • Third-party pricing services: industry-standard The following table presents a summary of the significant inputs used by our third-party pricing services for certain fair value measurements of fixed maturity securities that are classified as Level 2 as of June 30, 2017: (Amounts in millions) Fair value Primary methodologies Significant inputs U.S. government, agencies and government-sponsored enterprises $ 5,628 Price quotes from trading desk, broker feeds Bid side prices, trade prices, Option Adjusted Spread (“OAS”) to swap curve, Bond Market Association OAS, Treasury Curve, Agency Bullet Curve, maturity to issuer spread State and political subdivisions $ 2,761 Multi-dimensional attribute-based modeling systems, third-party pricing vendors Trade prices, material event notices, Municipal Market Data benchmark yields, broker quotes Non-U.S. government $ 2,075 Matrix pricing, spread priced to benchmark curves, price quotes from market makers Benchmark yields, trade prices, broker quotes, comparative transactions, issuer spreads, bid-offer spread, market research publications, third-party pricing sources U.S. corporate $ 24,722 Multi-dimensional attribute-based modeling systems, broker quotes, price quotes from market makers, internal models, OAS-based models Bid side prices to Treasury Curve, Issuer Curve, which includes sector, quality, duration, OAS percentage and change for spread matrix, trade prices, comparative transactions, Trade Reporting and Compliance Engine (“TRACE”) reports Non-U.S. corporate $ 10,569 Multi-dimensional attribute-based modeling systems, OAS-based models, price quotes from market makers Benchmark yields, trade prices, broker quotes, comparative transactions, issuer spreads, bid-offer spread, market research publications, third-party pricing sources Residential mortgage-backed $ 4,246 OAS-based models, To Be Announced pricing models, single factor binomial models, internally priced Prepayment and default assumptions, aggregation of bonds with similar characteristics, including collateral type, vintage, tranche type, weighted-average life, weighted-average loan age, issuer program and delinquency ratio, pay up and pay down factors, TRACE reports Commercial mortgage-backed $ 3,354 Multi-dimensional attribute-based modeling systems, pricing matrix, spread matrix priced to swap curves, Trepp commercial mortgage-backed securities analytics model Credit risk, interest rate risk, prepayment speeds, new issue data, collateral performance, origination year, tranche type, original credit ratings, weighted-average life, cash flows, spreads derived from broker quotes, bid side prices, spreads to daily updated swaps curves, TRACE reports Other asset-backed $ 3,042 Multi-dimensional attribute-based modeling systems, spread matrix priced to swap curves, price quotes from market makers, internal models Spreads to daily updated swaps curves, spreads derived from trade prices and broker quotes, bid side prices, new issue data, collateral performance, analysis of prepayment speeds, cash flows, collateral loss analytics, historical issue analysis, trade data from market makers, TRACE reports • Internal models: Equity securities. Securities lending 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. Level 3 measurements Fixed maturity securities • Internal models: • Broker quotes: Equity securities. 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. 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 June 30, 2017 and December 31, 2016, the impact of non-performance risk resulted in a lower fair value of our GMWB liabilities of $69 million and $73 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. Fixed index annuity embedded derivatives We have 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. Indexed universal life embedded derivatives We have indexed universal life 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. 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 have not recorded 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. Interest rate swaps related to securitization entities. Inflation indexed swaps. Foreign currency swaps. Credit default swaps. Credit default swaps related to securitization entities. Equity index options. Financial futures. Equity return swaps. Forward bond purchase commitments. Other foreign currency contracts. The following tables set forth our assets by class of instrument that are measured at fair value on a recurring basis as of the dates indicated: June 30, 2017 (Amounts in millions) Total Level 1 Level 2 Level 3 Assets Investments: Fixed maturity securities: U.S. government, agencies and government-sponsored enterprises $ 5,629 $ — $ 5,628 $ 1 State and political subdivisions 2,806 — 2,769 37 Non-U.S. government 2,091 — 2,091 — U.S. corporate: Utilities 4,848 — 4,210 638 Energy 2,370 — 2,210 160 Finance and insurance 6,590 — 5,729 861 Consumer—non-cyclical 4,782 — 4,660 122 Technology and communications 2,675 — 2,617 58 Industrial 1,344 — 1,283 61 Capital goods 2,287 — 2,169 118 Consumer—cyclical 1,599 — 1,333 266 Transportation 1,179 — 1,079 100 Other 397 — 221 176 Total U.S. corporate 28,071 — 25,511 2,560 Non-U.S. corporate: Utilities 1,053 — 694 359 Energy 1,434 — 1,257 177 Finance and insurance 2,590 — 2,418 172 Consumer—non-cyclical 746 — 617 129 Technology and communications 1,043 — 995 48 Industrial 1,015 — 903 112 Capital goods 574 — 425 149 Consumer—cyclical 494 — 427 67 Transportation 704 — 514 190 Other 2,777 — 2,736 41 Total non-U.S. corporate 12,430 — 10,986 1,444 Residential mortgage-backed 4,319 — 4,246 73 Commercial mortgage-backed 3,406 — 3,354 52 Other asset-backed 3,192 — 3,042 150 Total fixed maturity securities 61,944 — 57,627 4,317 Equity securities 855 734 73 48 Other invested assets: Derivative assets: Interest rate swaps 590 — 590 — Foreign currency swaps 5 — 5 — Equity index options 81 — — 81 Equity return swaps 2 — 2 — Other foreign currency contracts 65 — 65 — Total derivative assets 743 — 662 81 Securities lending collateral 226 — 226 — Total other invested assets 969 — 888 81 Restricted other invested assets related to securitization entities 81 — 81 — Reinsurance recoverable (1) 15 — — 15 Separate account assets 7,269 7,269 — — Total assets $ 71,133 $ 8,003 $ 58,669 $ 4,461 (1) Represents embedded derivatives associated with the reinsured portion of our GMWB liabilities.

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: Total realized and Total gains net income (Amounts in millions) Beginning Included in net income Included Purchases Sales Issuances Settlements Transfer (1) Transfer (1) Ending Fixed maturity securities: U.S. government, agencies and government-sponsored enterprises $ 1 $ — $ — $ — $ — $ — $ — $ — $ — $ 1 $ — State and political subdivisions 37 — — — — — — — — 37 — U.S. corporate: Utilities 578 — 13 30 — — — 30 (13 ) 638 — Energy 162 — 4 — — — (7 ) 1 — 160 — Finance and insurance 818 4 39 24 (7 ) — (3 ) — (14 ) 861 4 Consumer—non-cyclical 122 — — — — — — — — 122 — Technology and communications 59 — 5 4 — — — — (10 ) 58 — Industrial 47 — 1 13 — — — — — 61 — Capital goods 153 — 2 — — — — — (37 ) 118 — Consumer—cyclical 263 — 4 — — — (1 ) — — 266 — Transportation 97 — 4 — — — (1 ) — — 100 1 Other 142 — — — — — (3 ) 37 — 176 — Total U.S. corporate 2,441 4 72 71 (7 ) — (15 ) 68 (74 ) 2,560 5 Non-U.S. corporate: Utilities 386 — 3 — — — — — (30 ) 359 — Energy 206 — 3 — — — — — (32 ) 177 — Finance and insurance 168 1 4 4 — — (5 ) — — 172 1 Consumer—non-cyclical 129 — 1 — — — (1 ) — — 129 — Tech

Deferred Acquisition Costs	(7) Deferred Acquisition Costs The following table presents the activity impacting deferred acquisition costs (“DAC”) for the dates indicated: As of or for the six June 30, (Amounts in millions) 2017 2016 Unamortized beginning balance $ 4,241 $ 4,569 Impact of foreign currency translation 6 8 Costs deferred 44 91 Amortization, net of interest accretion (197 ) (177 ) Unamortized ending balance 4,094 4,491 Accumulated effect of net unrealized investment (gains) losses (1,716 ) (445 ) Ending balance $ 2,378 $ 4,046 We regularly review DAC to determine if it is recoverable from future income. In the second quarters of 2017 and 2016, we performed our loss recognition testing and determined that we had a premium deficiency in our fixed immediate annuity products. As of June 30, 2016, we wrote off the entire DAC balance for our fixed immediate annuity products of $14 million through amortization. In addition, as a result of our fixed immediate annuity loss recognition testing as of June 30, 2017 and 2016, we increased our future policy benefit reserves and recognized expenses of $22 million and $18 million, respectively. The premium deficiency test results were primarily driven by the low interest rate environments. As of June 30, 2017, we believe all of our other businesses had sufficient future income and therefore the related DAC was recoverable. In addition, we are required to analyze the impacts from net unrealized investment gains and losses on our available-for-sale investment securities backing insurance liabilities, as if those unrealized investment gains and losses were realized. These “shadow accounting” adjustments allow for the impact of recognizing unrealized gains and losses on related insurance assets and liabilities in a manner consistent with the recognition of the unrealized gains and losses on available-for-sale investment securities within the statements of comprehensive income and changes in equity. Changes to net unrealized investment (gains) losses may increase or decrease the ending DAC balance. Similar to a loss recognition event, when the DAC balance is reduced to zero, additional insurance liabilities are established if necessary. Unlike a loss recognition event, based on changes in net unrealized investment (gains) losses, these shadow adjustments may reverse from period to period. As of June 30, 2017, due primarily to the decline in interest rates increasing unrealized investments gains, we reduced the DAC balance of our long-term care insurance business to zero, a cumulative decrease in the accumulated effect of net unrealized investment gains of approximately $1.3 billion out of the total $1.7 billion in the table above, with an offsetting amount recorded in other comprehensive income. There was no impact to net income.

Liability for Policy and Contract Claims	(8) Liability for Policy and Contract Claims The following table sets forth changes in our liability for policy and contract claims as of the dates indicated: As of or for the six June 30, (Amounts in millions) 2017 2016 Beginning balance $ 9,256 $ 8,095 Less reinsurance recoverables (2,409 ) (2,122 ) Net beginning balance 6,847 5,973 Incurred related to insured events of: Current year 1,804 1,608 Prior years (244 ) 32 Total incurred 1,560 1,640 Paid related to insured events of: Current year (450 ) (443 ) Prior years (1,224 ) (1,162 ) Total paid (1,674 ) (1,605 ) Interest on liability for policy and contract claims 147 123 Foreign currency translation 18 10 Net ending balance 6,898 6,141 Add reinsurance recoverables 2,341 2,148 Ending balance $ 9,239 $ 8,289 The liability for policy and contract claims represents our current best estimate; however, there may be future adjustments to this estimate and related assumptions. Such adjustments, reflecting any variety of new and adverse trends, could possibly be significant, and result in increases in reserves by an amount that could be material to our results of operations and financial condition and liquidity. As of the six months ended June 30, 2017, the favorable development of $244 million related to insured events of prior years was primarily attributable to favorable claim terminations in our long-term care insurance business. To a lesser degree, our mortgage insurance businesses also experienced favorable prior year claim development from an improvement in net cures and aging of existing claims, as well as improvement in the estimated claim severity or amount.

Income Taxes	(9) Income Taxes The reconciliation of the federal statutory tax rate to the effective income tax rate was as follows for the periods indicated: Three months ended June 30, Six months ended June 30, (Amounts in millions) 2017 2016 2017 2016 Pre-tax income $ 401 $ 351 $ 733 $ 501 Statutory U.S. federal income tax rate $ 140 35.0 % $ 122 35.0 % $ 257 35.0 % $ 175 35.0 % Increase (reduction) in rate resulting from: State income tax, net of federal income tax effect 1 0.2 — — (2 ) (0.3 ) 1 0.2 Tax favored investments (3 ) (0.7 ) (2 ) (0.5 ) (2 ) (0.3 ) (3 ) (0.6 ) Effect of foreign operations (8 ) (2.0 ) (11 ) (3.2 ) (8 ) (1.0 ) (17 ) (3.4 ) Reversal of valuation allowance — — — — — — (25 ) (5.0 ) Stock-based compensation — — — — 1 0.2 3 0.6 Loss on sale of business — — 1 0.2 — — (1 ) (0.2 ) Other, net — — — (0.2 ) — — — (0.1 ) Effective rate $ 130 32.5 % $ 110 31.3 % $ 246 33.6 % $ 133 26.5 % For the three months ended June 30, 2017, the effective tax rate increased primarily attributable to a decrease in tax benefits from lower taxed foreign income. The increase was partially offset by an increase in tax favored investment benefits and tax impacts related to the sale of our mortgage insurance business in Europe in the prior year that did not recur. The effective tax rate for the six months ended June 30, 2017 increased primarily related to the reversal of a deferred tax valuation allowance related to our mortgage insurance business in Europe during the prior year, a decrease in tax benefits from lower taxed foreign income, and prior year true-ups recorded in the current year. These increases were partially offset by a decrease to tax expense related to stock based compensation in the current year.

Segment Information

Segment Information	6 Months Ended
	Jun. 30, 2017
Segment Information	(10) Segment Information We have the following five operating business segments: U.S. Mortgage Insurance; Canada Mortgage Insurance; Australia Mortgage Insurance; U.S Life Insurance (which includes our long-term care insurance, life insurance and fixed annuities businesses); and Runoff (which includes the results of non-strategic products which have not been actively sold). In addition to our five operating business segments, we also have Corporate and Other activities which include debt financing expenses that are incurred at the Genworth Holdings 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, including certain smaller international mortgage insurance businesses and discontinued operations. We allocate our consolidated provision for income taxes to our operating segments. Our allocation methodology applies a specific tax rate to the pre-tax income (loss) of each segment, which is then adjusted in each segment to reflect the tax attributes of items unique to that segment such as foreign income. The difference between the consolidated provision for income taxes and the sum of the provision for income taxes in each segment is reflected in Corporate and Other activities. The annually-determined tax rates and adjustments to each segment’s provision for income taxes are estimates which are subject to review and could change from year to year. We use the same accounting policies and procedures to measure segment income and assets as our consolidated net income and assets. Our chief operating decision maker evaluates segment performance and allocates resources on the basis of “adjusted operating income available to Genworth Financial, Inc.’s common stockholders.” We define adjusted operating income available to Genworth Financial, Inc.’s common stockholders as income 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, gains (losses) on the early extinguishment of debt, gains (losses) on insurance block transactions, restructuring costs and infrequent or unusual non-operating items. Gains (losses) on insurance block transactions are defined as gains (losses) on the early extinguishment of non-recourse funding obligations, early termination fees for other financing restructuring and/or resulting gains (losses) on reinsurance restructuring for certain blocks of business. 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, gains (losses) on the sale of businesses, gains (losses) on the early extinguishment of debt, gains (losses) on insurance block transactions and restructuring costs are also excluded from adjusted operating income available to Genworth Financial, Inc.’s common stockholders because, in our opinion, they are not indicative of overall operating trends. Infrequent or unusual non-operating items are also excluded from adjusted operating income available to Genworth Financial, Inc.’s common stockholders if, in our opinion, they are not indicative of overall operating trends. While some of these items may be significant components of net income available to Genworth Financial, Inc.’s common stockholders in accordance with U.S. GAAP, we believe that adjusted operating income available to Genworth Financial, Inc.’s common stockholders, and measures that are derived from or incorporate adjusted operating income available to Genworth Financial, Inc.’s common stockholders, are appropriate measures that are useful to investors because they identify the income attributable to the ongoing operations of the business. Management also uses adjusted operating income available to Genworth Financial, Inc.’s common stockholders 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 adjusted operating income available to Genworth Financial, Inc.’s common stockholders have occurred in the past and could, and in some cases will, recur in the future. Adjusted operating income available to Genworth Financial, Inc.’s common stockholders is not a substitute for net income available to Genworth Financial, Inc.’s common stockholders determined in accordance with U.S. GAAP. In addition, our definition of adjusted operating income available to Genworth Financial, Inc.’s common stockholders may differ from the definitions used by other companies. Adjustments to reconcile net income attributable to Genworth Financial, Inc.’s common stockholders and adjusted operating income available to Genworth Financial, Inc.’s common stockholders assume a 35% tax rate (unless otherwise indicated) and are net of the portion attributable to noncontrolling interests. Net investment gains (losses) are also adjusted for DAC and other intangible amortization and certain benefit reserves. In the first quarter of 2017, we recorded a pre-tax expense of $1 million related to restructuring costs as the company continues to evaluate and appropriately size its organizational needs and expenses. In the first quarter of 2016, we recorded a pre-tax loss of $7 million and a tax benefit of $27 million related to the planned sale of our mortgage insurance business in Europe; we paid a pre-tax make-whole expense of $20 million related to the early redemption of Genworth Holdings’ 2016 notes; we also repurchased $28 million principal amount of Genworth Holdings’ notes with various maturity dates for a pre-tax gain of $4 million; we completed a life block transaction resulting in a pre-tax loss of $9 million in connection with the early extinguishment of non-recourse funding obligations; and we recorded a pre-tax expense of $15 million related to restructuring costs as part of an expense reduction plan as the company evaluates and appropriately sizes its organizational needs and expenses. In the second quarter of 2016, we completed the sale of our mortgage insurance business in Europe and recorded an additional pre-tax loss of $2 million; we completed the sale of our term life insurance new business platform and recorded a pre-tax gain of $12 million; we settled restricted borrowings related to a securitization entity and recorded a $64 million pre-tax gain related to the early extinguishment of debt; and we recorded a pre-tax expense of $5 million related to restructuring costs as part of an expense reduction plan as the company evaluates and appropriately sizes its organizational needs and expenses. There were no infrequent or unusual items excluded from adjusted operating income during the periods presented other than the following item. We incurred fees during the first quarter of 2016 related to Genworth Holdings’ bond consent solicitation of $18 million for broker, advisor and investment banking fees. The following is a summary of revenues for our segments and Corporate and Other activities for the periods indicated: Three months ended June 30, Six months ended (Amounts in millions) 2017 2016 2017 2016 Revenues: U.S. Mortgage Insurance segment $ 189 $ 176 $ 376 $ 351 Canada Mortgage Insurance segment 204 147 373 307 Australia Mortgage Insurance segment 97 113 219 218 U.S. Life Insurance segment: Long-term care insurance 1,036 1,119 2,030 2,071 Life insurance 411 412 828 535 Fixed annuities 210 189 415 395 U.S. Life Insurance segment 1,657 1,720 3,273 3,001 Runoff segment 89 65 176 134 Corporate and Other activities (13 ) 15 (23 ) 10 Total revenues $ 2,223 $ 2,236 $ 4,394 $ 4,021 The increase in total revenues for the six months ended June 30, 2017 was primarily attributable to our U.S. Life Insurance segment driven mostly by a life block transaction in our life insurance business in the first quarter of 2016, under which we initially ceded $326 million of certain term life insurance premiums. The following tables present the reconciliation of net income available to Genworth Financial, Inc.’s common stockholders to adjusted operating income available to Genworth Financial, Inc.’s common stockholders for our segments and Corporate and Other activities and a summary of adjusted operating income available to Genworth Financial, Inc.’s common stockholders for our segments and Corporate and Other activities for the periods indicated: Three months ended June 30, Six months ended June 30, (Amounts in millions) 2017 2016 2017 2016 Net income available to Genworth Financial, Inc.’s common stockholders $ 202 $ 172 $ 357 $ 225 Add: net income attributable to noncontrolling interests 69 48 130 103 Net income 271 220 487 328 Loss from discontinued operations, net of taxes — (21 ) — (40 ) Income from continuing operations 271 241 487 368 Less: income from continuing operations attributable to noncontrolling interests 69 48 130 103 Income from continuing operations available to Genworth Financial, Inc.’s common stockholders 202 193 357 265 Adjustments to income from continuing operations available to Genworth Financial, Inc.’s common stockholders: Net investment (gains) losses, net (1) (79 ) (39 ) (99 ) (20 ) Gains from sale of businesses — (10 ) — (3 ) Gains on early extinguishment of debt, net — (64 ) — (48 ) Losses from life block transactions — — — 9 Expenses related to restructuring — 5 1 20 Fees associated with bond consent solicitation — — — 18 Taxes on adjustments 28 38 35 (15 ) Adjusted operating income available to Genworth Financial, Inc.’s common stockholders $ 151 $ 123 $ 294 $ 226 (1) For the three months ended June 30, 2017 and 2016, net investment (gains) losses were adjusted for DAC and other intangible amortization and certain benefit reserves of zero and $(6) million, respectively, and adjusted for net investment (gains) losses attributable to noncontrolling interests of $22 million and $(3) million, respectively. For the six months ended June 30, 2017 and 2016, net investment (gains) losses were adjusted for DAC and other intangible amortization and certain benefit reserves of zero and $(15) million, respectively, and adjusted for net investment (gains) losses attributable to noncontrolling interests of $36 million and $6 million, respectively.

Commitments and Contingencies

Commitments and Contingencies	6 Months Ended

Commitments and Contingencies	(11) Commitments and Contingencies (a) Litigation and Regulatory Matters 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, product 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 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, post-closing obligations associated with previous dispositions and securities lawsuits. 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. In April 2014, Genworth Financial, Inc., its former chief executive officer and its then current chief financial officer were named in a putative class action lawsuit captioned City of Hialeah Employees’ Retirement System v. Genworth Financial, Inc. et al. In re Genworth Financial, Inc. Securities Litigation. In January 2016, Genworth Financial, Inc., its current chief executive officer, its former chief executive officer, its former chief financial officer and current and former members of its board of directors were named in a shareholder derivative suit filed by International Union of Operating Engineers Local No. 478 Pension Fund, Richard L.

Genworth Life and Annuity Insurance Company Avazian, et al v. Genworth Life and Annuity Insurance Company, et al, At this time, other than as noted above, 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. Except as disclosed above, we also are not able to provide an estimate or range of reasonably possible losses related to these matters. Therefore, we cannot ensure that the current investigations and proceedings will not have a material adverse effect on our business, financial condition or results of operations. In addition, it is possible that related investigations and proceedings may be commenced in the future, and we could become subject to additional unrelated investigations and lawsuits. Increased regulatory scrutiny and any resulting investigations or proceedings could result in new legal precedents and industry-wide regulations or practices that could adversely affect our business, financial condition and results of operations. (b) Commitments As of June 30, 2017, we were committed to fund $268 million in limited partnership investments, $23 million in U.S. commercial mortgage loan investments and $36 million in private placement investments.

Condensed Consolidating Financial Information	(13) Condensed Consolidating Financial Information Genworth Financial provides a full and unconditional guarantee to the trustee of Genworth Holdings’ outstanding senior notes and the holders of the senior notes, on an unsecured unsubordinated basis, of the full and punctual payment of the principal of, premium, if any and interest on, and all other amounts payable under, each outstanding series of senior notes, and the full and punctual payment of all other amounts payable by Genworth Holdings under the senior notes indenture in respect of such senior notes. Genworth Financial also provides a full and unconditional guarantee to the trustee of Genworth Holdings’ outstanding subordinated notes and the holders of the subordinated notes, on an unsecured subordinated basis, of the full and punctual payment of the principal of, premium, if any and interest on, and all other amounts payable under, the outstanding subordinated notes, and the full and punctual payment of all other amounts payable by Genworth Holdings under the subordinated notes indenture in respect of the subordinated notes. Genworth Holdings is a direct, 100% owned subsidiary of Genworth Financial. The following condensed consolidating financial information of Genworth Financial and its direct and indirect subsidiaries have been prepared pursuant to rules regarding the preparation of consolidating financial information of Regulation S-X.

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 and contractholders, not stockholders. Any dividends in excess of limits are deemed “extraordinary” and require approval. Based on statutory results as of December 31, 2016, in accordance with applicable dividend restrictions, our subsidiaries could pay dividends of approximately $220 million to us in 2017 without obtaining regulatory approval, and the remaining net assets are considered restricted. While the $220 million is unrestricted, we do not expect our insurance subsidiaries to pay dividends to us in 2017 at this level as they need to retain capital for growth and to meet capital requirements and desired thresholds. As of June 30, 2017, Genworth Financial’s and Genworth Holdings’ subsidiaries had restricted net assets of $12.9 billion and $12.3 billion, respectively.

Accounting Changes (Policies)

Accounting Changes (Policies)	6 Months Ended
	Jun. 30, 2017
Accounting Pronouncement Recently Adopted	Accounting Pronouncements Recently Adopted On January 1, 2017, we adopted new accounting guidance related to the accounting for stock compensation. The guidance primarily simplifies the accounting for employee share-based payment transactions, including a new requirement to record all of the income tax effects at settlement or expiration through the income statement, classifications of awards as either equity or liabilities, and classification on the statement of cash flows. We adopted this new accounting guidance on a modified retrospective basis and recorded a previously disallowed deferred tax asset of $9 million with a corresponding increase to cumulative effect of change in accounting within retained earnings at adoption. On January 1, 2017, we adopted new accounting guidance related to transition to the equity method of accounting. The guidance eliminates the retrospective application of the equity method of accounting when obtaining significant influence over a previously held investment. The guidance requires that an entity that has an available-for-sale equity security that becomes qualified for the equity method of accounting recognize through earnings the unrealized holding gain or loss in accumulated other comprehensive income at the date the investment becomes qualified for use of the equity method. We did not have any significant impact from this guidance on our consolidated financial statements. On January 1, 2017, we adopted new accounting guidance related to the assessment of contingent put and call options in debt instruments. The guidance clarifies the requirements for assessing whether contingent call (put) options that can accelerate the payment of principal on debt instruments are clearly and closely related to their debt hosts. An entity performing the assessment under the amendments in this update is required to assess the embedded call (put) options solely in accordance with the four-step decision sequence. This guidance is consistent with our previous accounting practices and, accordingly, did not have any impact on our consolidated financial statements. On January 1, 2017, we adopted new accounting guidance related to the effect of derivative contract novations on existing hedge accounting relationships. The guidance clarifies that a change in the counterparty to a derivative instrument that has been designated as the hedging instrument does not, in and of itself, require dedesignation of that hedging relationship provided that all other hedge accounting criteria continue to be met. This guidance is consistent with our previous accounting for derivative contract novations and, accordingly, did not have any impact on our consolidated financial statements.
Accounting Pronouncements Not Yet Adopted	Accounting Pronouncements Not Yet Adopted In May 2017, the Financial Accounting Standards Board (“the FASB”) issued new guidance to clarify when to account for a change to share-based compensation as a modification. The new guidance requires modification accounting only if there are changes to the fair value, vesting conditions or classification, as a liability or equity, of the share-based compensation. The guidance is effective, prospectively, for us on January 1, 2018, accordingly, the guidance will not have any impact at adoption. In March 2017, the FASB issued new guidance shortening the amortization period for the premium component of callable debt securities purchased at a premium. The guidance requires the premium to be amortized to the earliest call date. This change does not apply to securities held at a discount. The guidance is currently effective for us on January 1, 2019, with early adoption permitted. We are in process of evaluating the impact the guidance may have on our consolidated financial statements. In February 2017, the FASB issued new guidance to clarify the accounting for gains and losses from the derecognition of nonfinancial assets and accounting for partial sales of nonfinancial assets. The new guidance clarifies when transferring ownership interests in a consolidated subsidiary holding nonfinancial assets is within scope. It also states that the reporting entity should identify each distinct nonfinancial asset and derecognize when a counterparty obtains control, and clarifies the accounting for partial sales. The new guidance is currently effective for us on January 1, 2018. We do not expect any significant impacts from this guidance on our consolidated financial statements. In January 2017, the FASB issued new guidance simplifying the test for goodwill impairment. The new guidance states goodwill impairment is equal to the difference between the carrying value and fair value of the reporting unit up to the amount of recorded goodwill. The new guidance is currently effective for us on January 1, 2020, with early adoption permitted for testing dates after January 1, 2017. We do not expect any significant impacts from this new guidance on our consolidated financial statements. In October 2016, the FASB issued new guidance related to the income tax effects of intra-entity transfers of assets other than inventory. The new guidance states that an entity should recognize the income tax consequences of an intra-entity transfer of an asset other than inventory when the transfer occurs. The guidance is currently effective for us on January 1, 2018. We are still in process of evaluating the impact the guidance may have on our consolidated financial statements, including any cumulative effect adjustment that will be recorded directly to retained earnings as of the beginning of the period of adoption.
