[1]	Under applicable accounting guidance, companies in a loss position are required to use basic weighted-average common shares outstanding in the calculation of diluted loss per share. Therefore, as a result of our loss from continuing operations available to Genworth Financial, Inc.'s common stockholders for the three and nine months ended September 30, 2016, we were required to use basic weighted-average common shares outstanding in the calculation of diluted loss per share, as the inclusion of shares for stock options, restricted stock units and stock appreciation rights of 2.2 million and 1.8 million, respectively, would have been antidilutive to the calculation. If we had not incurred a loss from continuing operations available to Genworth Financial, Inc.'s common stockholders for the three months and nine months ended September 30, 2016, dilutive potential weighted-average common shares outstanding would have been 500.5 million and 500.1 million, respectively.

	Sep. 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. non-strategic non-strategic 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.

Accounting Changes

Accounting Changes	9 Months Ended
	Sep. 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 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 August 2017, the Financial Accounting Standards Board (“the FASB”) issued new guidance intended to enable entities to better portray the economics of their derivative risk management activities in the financial statements and enhance the transparency and understandability of hedge results. In certain situations, the amendments also simplify the application of hedge accounting. The guidance is currently effective for us on January 1, 2019, with early adoption permitted. We are in process of evaluating adopting this new guidance early and the impact it may have on our consolidated financial statements. In May 2017, 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. In January 2016, the FASB issued new accounting guidance related to the recognition and measurement of financial assets and financial liabilities. Changes to the current financial instruments accounting primarily affects equity investments, financial liabilities under the fair value option, and the presentation and disclosure requirements for financial instruments. Under the new guidance, equity investments with readily determinable fair value, except those accounted for under the equity method of accounting, will be measured at fair value with changes in fair value recognized in net income (loss). As of September 30, 2017, we have approximately $45 million of cumulative unrealized gains related to equity securities included in accumulated other comprehensive income as well as approximately $25 million of gains related to limited partnership investments currently recorded at cost, that will be reclassed to cumulative effect of change in accounting within retained earnings upon adoption of this new accounting guidance. The new guidance also clarifies that the need for a valuation allowance on a deferred tax asset related to available-for-sale

Therefore, as a result of our loss from continuing operations available to Genworth Financial, Inc.’s common stockholders for the three and nine months ended September 30, 2016, we were required to use basic weighted-average common shares outstanding in the calculation of diluted loss per share, as the inclusion of shares for stock options, restricted stock units and stock appreciation rights of 2.2 million and 1.8 million, respectively, would have been antidilutive to the calculation. If we had not incurred a loss from continuing operations available to Genworth Financial, Inc.’s common stockholders for the three months and nine months ended September 30, 2016, dilutive potential weighted-average common shares outstanding would have been 500.5 million and 500.1 million, respectively.

We generally intend to hold securities in unrealized loss positions until they recover. However, from time to time, our intent on an individual security may change, based upon market or other unforeseen developments. In such instances, we sell securities in the ordinary course of managing our portfolio to meet diversification, credit quality, yield and liquidity requirements. If a loss is recognized from a sale subsequent to a balance sheet date due to these unexpected developments, the loss is recognized in the period in which we determined that we have the intent to sell the securities or it is more likely than not that we will be required to sell the securities prior to recovery. The aggregate fair value of securities sold at a loss during the three months ended September 30, 2017 and 2016 was $286 million and $293 million, respectively, which was approximately 97% and 95%, respectively, of book value. The aggregate fair value of securities sold at a loss during the nine months ended September 30, 2017 and 2016 was $1,390 million and $833 million, respectively, which was approximately 96% and 93%, respectively, of book value.

in the tables above, the majority of the securities in a continuous unrealized loss position for less than 12 months were investment grade and less than 20% below cost. These unrealized losses were primarily attributable to increase in interest rates, 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 September 30, 2017. Fixed Maturity Securities In A Continuous Unrealized Loss Position For 12 Months Or More Of the $88 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 “A” and approximately 92% of the unrealized losses were related to investment grade securities as of September 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 September 30, 2017. As of September 30, 2017, the company did not have any 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.

As of September 30, 2017, none of our commercial mortgage loans were greater than 90 days past due. During the nine months ended September 30, 2017 and the year ended December 31, 2016, we modified or extended 7 and 16 commercial mortgage loans, respectively, with a total carrying value of $19 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.

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.

(f) Restricted Commercial Mortgage Loans Related To Securitization Entities We have a consolidated securitization entity that holds commercial mortgage loans that are recorded as restricted commercial mortgage loans related to securitization entities. (g) Restricted Other Invested Assets Related To Securitization Entities We previously had consolidated securitization entities that held certain investments that were recorded as restricted other invested assets related to securitization entities. The consolidated securitization entities held certain investments as trading securities whereby the changes in fair value were recorded in current period income (loss). The trading securities comprised asset-backed securities, including highly rated bonds that were primarily backed by credit card receivables. In 2017, these trading securities were sold as we repositioned these assets in connection with the maturity of the associated liabilities. (h) Limited Partnerships or Similar Entities Investments in partnerships or similar entities are generally considered VIEs when the equity group lacks sufficient financial control. Generally, these investments are limited partner or non-managing

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 September 30, (5) December 31, Balance sheet classification September 30, (5) December 31, Derivatives designated as Cash flow hedges: Interest rate swaps Other invested $ 70 $ 237 Other liabilities $ 39 $ 203 Foreign currency swaps Other invested 2 4 Other liabilities — — Total cash flow hedges 72 241 39 203 Total derivatives 72 241 39 203 Derivatives not designated as Interest rate swaps Other invested — 359 Other liabilities — 146 Foreign currency swaps Other invested 10 — Other liabilities — 5 Credit default swaps related to Restricted other invested assets — — Other liabilities — 1 Equity index options Other 81 72 Other liabilities — — Financial futures Other — — Other liabilities — — Equity return swaps Other — 1 Other liabilities 2 1 Other foreign currency Other invested 98 35 Other liabilities 23 27 GMWB embedded derivatives Reinsurance recoverable (1) 14 16 Policyholder account balances (2) 257 303 Fixed index annuity embedded Other assets — — Policyholder account balances (3) 394 344 Indexed universal life embedded derivatives Reinsurance recoverable — — Policyholder account balances (4) 14 11 Total derivatives not 203 483 690 838 Total derivatives $ 275 $ 724 $ 729 $ 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. (5) In the third quarter of 2017, recent central clearing parties rule changes impacted our accounting treatment for variation margin pertaining to cleared swap positions, which was previously considered cash collateral and is now treated as daily settlements of the derivative contract. The change reduced the value of our derivative assets and derivative liabilities by $509 million and $274 million, respectively, in the third quarter of 2017. 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/ September 30, Derivatives designated as hedges Cash flow hedges: Interest rate swaps Notional $ 11,570 $ — $ (306 ) $ 11,264 Foreign currency swaps Notional 22 — — 22 Total cash flow hedges 11,592 — (306 ) 11,286 Total derivatives designated as hedges 11,592 — (306 ) 11,286 Derivatives not designated as hedges Interest rate swaps Notional 4,679 — — 4,679 Foreign currency swaps Notional 201 95 (14 ) 282 Credit default swaps Notional 39 — — 39 Credit default swaps related to securitization entities Notional 312 — (200 ) 112 Equity index options Notional 2,396 1,584 (1,484 ) 2,496 Financial futures Notional 1,398 4,300 (4,376 ) 1,322 Equity return swaps Notional 165 186 (258 ) 93 Other foreign currency contracts Notional 3,130 2,163 (691 ) 4,602 Total derivatives not designated as hedges 12,320 8,328 (7,023 ) 13,625 Total derivatives $ 23,912 $ 8,328 $ (7,329 ) $ 24,911 (Number of policies) Measurement December 31, Additions Maturities/ September 30, Derivatives not designated as hedges GMWB embedded derivatives Policies 33,238 — (2,127 ) 31,111 Fixed index annuity embedded derivatives Policies 17,549 — (367 ) 17,182 Indexed universal life embedded derivatives Policies 1,074 1 (66 ) 1,009 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 (Amounts in millions) 2017 2016 Derivatives qualifying as effective accounting hedges as of July 1 $ 2,064 $ 2,439 Current period increases (decreases) in fair value, net of deferred taxes of $(6) and $(40) 10 72 Reclassification to net (income), net of deferred taxes of $12 and $9 (22 ) (18 ) Derivatives qualifying as effective accounting hedges as of September 30 $ 2,052 $ 2,493 Nine months (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 $(17) and $(273) 29 507 Reclassification to net (income), net of deferred taxes of $35 and $31 (62 ) (59 ) Derivatives qualifying as effective accounting hedges as of September 30 $ 2,052 $ 2,493 The total of derivatives designated as cash flow hedges of $2,052 million, net of taxes, recorded in stockholders’ equity as of September 30, 2017 is expected to be reclassified to net income (loss) 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, $95 million, net of taxes, is expected to be reclassified to net income (loss) 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 nine months ended September 30, 2017, there was approximately $2 million reclassified to net income (loss) 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 non-functional 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.

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: September 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 $ 262 $ 66 $ 196 $ 724 $ 387 $ 337 Gross amounts offset in the balance sheet — — — — — — Net amounts presented in the balance sheet 262 66 196 724 387 337 Gross amounts not offset in the balance sheet: Financial instruments (3) (24 ) (24 ) — (172 ) (172 ) — Collateral received (164 ) — (164 ) (467 ) — (467 ) Collateral pledged — (301 ) 301 — (557 ) 557 Over collateralization 8 259 (251 ) 1 344 (343 ) Net amount $ 82 $ — $ 82 $ 86 $ 2 $ 84 (1) Included $1 million and $16 million of accruals on derivatives classified as other assets and does not include amounts related to embedded derivatives as of September 30, 2017 and December 31, 2016, respectively. (2) Included $2 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 September 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 $82 million and $86 million as of September 30, 2017 and December 31, 2016, respectively, or have been required to disburse up to $2 million as of December 31, 2016. There were no amounts that we would have been required to disburse as of September 30, 2017 . 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 Instrum

Fair Value of Financial Instruments	9 Months Ended

Fair Value of Financial Instruments	(6) Fair Value of Financial Instruments Assets and liabilities that are reflected in the accompanying 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, short-term investments, 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 Borrowings related to securitization entities. Investment contracts.

Recurring Fair Value Measurements We have fixed maturity, short-term investments, 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, short-term investments, equity and trading securities The fair value of fixed maturity, short-term investments, 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 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 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 pre-defined 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 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: 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 September 30, 2017: (Amounts in millions) Fair value Primary methodologies Significant inputs U.S. government, agencies and government-sponsored enterprises $ 5,669 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 $ 2,816 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. $ 2,210 Matrix pricing, spread priced to benchmark curves, price quotes from market makers Benchmark yields, trade prices, broker quotes, comparative transactions, issuer spreads, bid-offer U.S. corporate $ 25,290 Multi-dimensional attribute-based modeling systems, broker quotes, price quotes from market makers, internal models, OAS-based 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. $ 10,711 Multi-dimensional attribute-based modeling systems, OAS-based Benchmark yields, trade prices, broker quotes, comparative transactions, issuer spreads, bid-offer Residential mortgage-backed $ 4,123 OAS-based 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 $ 3,392 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 $ 2,843 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: non-U.S. non-U.S. 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. Short-term Investments Short-term investments primarily include commercial paper and other highly liquid debt instruments and are classified as Level 2. We determine fair value after considering prices obtained by third-party pricing services. Level 3 measurements Fixed maturity securities • Internal models: non-U.S. • Broker quotes: non-U.S. Equity securities. Restricted other invested assets related to securitization entities We previously held trading securities related to securitization entities that were classified as restricted other invested assets and were carried at fair value. The trading securities represented asset-backed securities. In 2017, these trading securities were sold as we repositioned these assets in connection with the maturity of the associated liabilities. The valuation for trading securities was determined using a market approach and/or an income approach depending on the availability of information. For certain highly rated asset-backed securities, there was observable market information for transactions of the same or similar instruments, which was provided to us by a third-party pricing service and was classified as Level 2. For certain securities that are not actively traded, we determined fair value after considering third-party broker provided prices or discounted expected cash flows using current yields for similar securities and classified 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 non-performance non-performance To determine the appropriate discount rate to reflect the non-performance non-performance non-performance 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 non-performance 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 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 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 non-performance non-performance non-performance 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.

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: (Amounts in millions) Beginning as of Total realized and Purchases Sales Issuances Settlements Transfer (1) Transfer (1) Ending as of Total gains in net attributable Included in net Included Fixed maturity securities: U.S. government, agencies $ 1 $ — $ — $ — $ — $ — $ — $ — $ — $ 1 $ — State and political subdivisions 37 1 (1 ) — — — — — — 37 1 U.S. corporate: Utilities 638 — — 26 — — (2 ) — — 662 — Energy 160 — — — — — (2 ) — — 158 — Finance and insurance 861 3 (52 ) 22 (14 ) — (157 ) 8 (1 ) 670 2 Consumer—non-cyclical 122 — 1 4 — — — — — 127 — Technology and 58 1 (3 ) — — — (1 ) — (3 ) 52 1 Industrial 61 — — — — — — — (14 ) 47 — Capital goods 118 1 — — — — (1 ) — — 118 1 Consumer—cyclical 266 — — — — — (2 ) — (2 ) 262 — Transportation 100 16 (10 ) — — — (45 ) — — 61 — Other 176 — — — (4 ) — (2 ) — — 170 — Total U.S. corporate 2,560 21 (64 ) 52 (18 ) — (212 ) 8 (20 ) 2,327 4 Non-U.S. Utilities 359 — — — — — — — — 359 — Energy 177 — 1 — — — (1 ) — — 177 — Finance and insurance 172 1 1 — — — (5 ) — — 169 — Consumer—non-cyclical 129 — — — — — — — — 129 — Technology and 48 1 1 — (21 ) — — — — 29 — Industrial 112 — — 13 — — — 14 — 139 — Capital goods 149 — 1 — — — — — — 150 — Consumer—cyclical 67 — — — — — — 2 — 69 — Transportation 190 — 1 — — — (10 ) — — 181 — Other 41 (2 ) 1 — (2 ) — — 11 — 49 — Total non-U.S. 1,444 — 6 13 (23 ) — (16 ) 27 — 1,451 — Residential mortgage-backed 73 — — 22 — — (1 ) — (8 ) 86 — Commercial mortgage-backed 52 (1 ) (2 ) 14 — — — — (41 ) 22 — Other asset-backed 150 (1 ) 1 52 — — (5 ) 44 (16 ) 225 — Total fixed maturity securities 4,317 20 (60 ) 153 (41 ) — (234 ) 79 (85 ) 4,149 5 Equity securities 48 — — — (1 ) — — — (3 ) 44 — Other invested assets: Derivative assets: Equity index options 81 16 — 15 — — (31 ) — — 81 13 Total derivative assets 81 16 — 15 — — (31 ) — — 81 13 Total other invested assets 81 16 — 15 — — (31 ) — — 81 13 Reinsurance recoverable (2) 15 (1 ) — — — — — — — 14 (1 ) Total Level 3 assets $ 4,461 $ 35 $ (60 ) $ 168 $ (42 ) $ — $ (265 ) $ 79 $ (88 ) $ 4,288 $ 17 (1) The transfers into and out of Level 3 for fixed maturity securities were related to changes in the primary pricing source and changes in the observability of external information used in determining the fair value, such as external ratings or credit spreads, as well as changes in the industry sectors assigned to specific securities.

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 nine months (Amounts in millions) 2017 2016 Unamortized beginning balance $ 4,241 $ 4,569 Impact of foreign currency translation 12 8 Costs deferred 67 124 Amortization, net of interest accretion (261 ) (257 ) Unamortized ending balance 4,059 4,444 Accumulated effect of net unrealized investment (gains) losses (1,717 ) (462 ) Ending balance $ 2,342 $ 3,982 We regularly review DAC to determine if it is recoverable from future income. In 2017 and 2016, we performed loss recognition testing and determined that we had premium deficiencies 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 September 30, 2017 and 2016, we increased our future policy benefit reserves and recognized expenses of $31 million and $24 million, respectively. The premium deficiency test results were primarily driven by the low interest rate environment. As of September 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 available-for-sale

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 nine months ended September 30, 2017, the favorable development of $306 million related to insured events of prior years was primarily attributable to favorable claim terminations in our long-term care insurance business. Our mortgage insurance businesses also experienced favorable prior year claim development mostly from an improvement in net cures and aging of existing claims, as well as lower delinquencies and an improvement in the estimated claim severity or amount.

The effective tax rate for the three and nine months ended September 30, 2016 was impacted by a valuation allowance of $265 million recorded on deferred tax assets related to foreign tax credits that we no longer expect to realize. The effective tax rate for the nine months ended September 30, 2016 was also impacted by the reversal of a deferred tax valuation allowance related to our mortgage insurance business in Europe due to taxable gains supporting the recognition of these deferred tax assets in the prior year.

Segment Information

Segment Information	9 Months Ended

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 We allocate our consolidated provision for income taxes to our operating segments. Our allocation methodology applies a specific tax rate to the pre-tax We use the same accounting policies and procedures to measure segment income (loss) and assets as our consolidated net income (loss) and assets. Our chief operating decision maker evaluates segment performance and allocates resources on the basis of “adjusted operating income (loss) available to Genworth Financial, Inc.’s common stockholders.” We define adjusted operating income (loss) available to Genworth Financial, Inc.’s common stockholders as income (loss) from continuing operations excluding the after-tax non-operating non-recourse non-operating non-operating While some of these items may be significant components of net income (loss) available to Genworth Financial, Inc.’s common stockholders in accordance with U.S. GAAP, we believe that adjusted operating income (loss) available to Genworth Financial, Inc.’s common stockholders, and measures that are derived from or incorporate adjusted operating income (loss) available to Genworth Financial, Inc.’s common stockholders, are appropriate measures that are useful to investors because they identify the income (loss) attributable to the ongoing operations of the business. Management also uses adjusted operating income (loss) 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 (loss) 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 (loss) available to Genworth Financial, Inc.’s common stockholders is not a substitute for net income (loss) available to Genworth Financial, Inc.’s common stockholders determined in accordance with U.S. GAAP. In addition, our definition of adjusted operating income (loss) available to Genworth Financial, Inc.’s common stockholders may differ from the definitions used by other companies. Adjustments to reconcile net income (loss) attributable to Genworth Financial, Inc.’s common stockholders and adjusted operating income (loss) 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. We recorded a pre-tax In the third quarter of 2016, we recorded a pre-tax In the second quarter of 2016, we completed the sale of our mortgage insurance business in Europe and recorded an additional pre-tax pre-tax pre-tax pre-tax In the first quarter of 2016, we recorded a pre-tax pre-tax pre-tax pre-tax non-recourse pre-tax There were no infrequent or unusual items excluded from adjusted operating income (loss) 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.

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 September 30, 2017, Genworth Financial’s and Genworth Holdings’ subsidiaries had restricted net assets of $13.0 billion and $12.2 billion, respectively.

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 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 August 2017, the Financial Accounting Standards Board (“the FASB”) issued new guidance intended to enable entities to better portray the economics of their derivative risk management activities in the financial statements and enhance the transparency and understandability of hedge results. In certain situations, the amendments also simplify the application of hedge accounting. The guidance is currently effective for us on January 1, 2019, with early adoption permitted. We are in process of evaluating adopting this new guidance early and the impact it may have on our consolidated financial statements. In May 2017, 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. In January 2016, the FASB issued new accounting guidance related to the recognition and measurement of financial assets and financial liabilities. Changes to the current financial instruments accounting primarily affects equity investments, financial liabilities under the fair value option, and the presentation and disclosure requirements for financial instruments. Under the new guidance, equity investments with readily determinable fair value, except those accounted for under the equity method of accounting, will be measured at fair value with changes in fair value recognized in net income (loss). As of September 30, 2017, we have approximately $45 million of cumulative unrealized gains related to equity securities included in accumulated other comprehensive income as well as approximately $25 million of gains related to limited partnership investments currently recorded at cost, that will be reclassed to cumulative effect of change in accounting within retained earnings upon adoption of this new accounting guidance. The new guidance also clarifies that the need for a valuation allowance on a deferred tax asset related to available-for-sale

Therefore, as a result of our loss from continuing operations available to Genworth Financial, Inc.’s common stockholders for the three and nine months ended September 30, 2016, we were required to use basic weighted-average common shares outstanding in the calculation of diluted loss per share, as the inclusion of shares for stock options, restricted stock units and stock appreciation rights of 2.2 million and 1.8 million, respectively, would have been antidilutive to the calculation. If we had not incurred a loss from continuing operations available to Genworth Financial, Inc.’s common stockholders for the three months and nine months ended September 30, 2016, dilutive potential weighted-average common shares outstanding would have been 500.5 million and 500.1 million, respectively.

[1]	Under applicable accounting guidance, companies in a loss position are required to use basic weighted-average common shares outstanding in the calculation of diluted loss per share. Therefore, as a result of our loss from continuing operations available to Genworth Financial, Inc.'s common stockholders for the three and nine months ended September 30, 2016, we were required to use basic weighted-average common shares outstanding in the calculation of diluted loss per share, as the inclusion of shares for stock options, restricted stock units and stock appreciation rights of 2.2 million and 1.8 million, respectively, would have been antidilutive to the calculation. If we had not incurred a loss from continuing operations available to Genworth Financial, Inc.'s common stockholders for the three months and nine months ended September 30, 2016, dilutive potential weighted-average common shares outstanding would have been 500.5 million and 500.1 million, respectively.

[1]	In the third quarter of 2017, recent central clearing parties rule changes impacted our accounting treatment for variation margin pertaining to cleared swap positions, which was previously considered cash collateral and is now treated as daily settlements of the derivative contract. The change reduced the value of our derivative assets and derivative liabilities by $509 million and $274 million, respectively, in the third quarter of 2017.
