	Jun. 30, 2018
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 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 Financial’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. 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 2017 Annual Report on Form 10-K.

Accounting Changes

Accounting Changes	6 Months Ended
	Jun. 30, 2018
Accounting Changes	(2) Accounting Changes Accounting Pronouncements Recently Adopted On January 1, 2018, we early adopted new accounting guidance on the reclassification from accumulated other comprehensive income to retained earnings for stranded tax effects resulting from the Tax Cuts and Jobs Act (“TCJA”), or “stranded tax effects.” Under current U.S. GAAP, deferred tax assets and liabilities are adjusted for the effect of a change in tax laws or rates with the effect included in income from continuing operations in the period that the changes were enacted. This also includes situations in which the related tax effects were originally recognized in other comprehensive income as opposed to income from continuing operations. The following summarizes the components for the cumulative effect adjustment recorded on January 1, 2018 related to the adoption of this new accounting guidance: Accumulated other comprehensive income (loss) (Amounts in millions) Net unrealized Derivatives Foreign currency Retained Total Deferred taxes: Net unrealized gains on investment securities $ 192 $ — $ — $ (192 ) $ — Net unrealized gains on derivatives — 12 — (12 ) — Investment in foreign subsidiaries (3 ) — (46 ) 49 — Accrued commission and general expenses — — (1 ) 1 — Cumulative effect of changes in accounting $ 189 $ 12 $ (47 ) $ (154 ) $ — The accounting for the temporary differences related to investment in foreign subsidiaries recorded in accumulated other comprehensive income (loss) at adoption of the TCJA, were provisional. Therefore, additional reclassification adjustments may be recorded in future periods as tax effects of the TCJA on related temporary differences are finalized. However, no reclassification adjustments were recorded in the second quarter of 2018. Other than those effects related to the TCJA, our policy is to release stranded tax effects from accumulated other comprehensive income (loss) using the portfolio approach for items related to investments and derivatives, and upon disposition of a subsidiary for items related to outside basis differences. On January 1, 2018, we early adopted new accounting guidance related to the hedge accounting model. The new guidance amends the hedge accounting model 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 and removed the requirements to separately measure and report hedge ineffectiveness. We adopted this new accounting using the modified retrospective method and recognized a gain of $2 million in accumulated other comprehensive income with a corresponding decrease to retained earnings at adoption. This gain was the cumulative amount of hedge ineffectiveness related to active hedges that was previously included in earnings. On January 1, 2018, we adopted new accounting guidance that clarifies 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. We adopted this new accounting guidance prospectively and therefore, the guidance did not have any impact at adoption. On January 1, 2018, we adopted new accounting guidance that clarifies the scope and accounting for gains and losses from the derecognition of nonfinancial assets or an in substance nonfinancial asset that is not a business 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. We adopted this new accounting guidance using the modified retrospective method, which had no impact on our consolidated financial statements at adoption. On January 1, 2018, we early adopted new accounting 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. We adopted this new accounting guidance prospectively and will apply it to our 2018 goodwill impairment test. On January 1, 2018, we adopted new accounting guidance related to the classification and presentation of changes in restricted cash. The new guidance requires that changes in the total of cash, cash equivalents, restricted cash and restricted cash equivalents be shown in the statements of cash flows and requires additional disclosures related to restricted cash and restricted cash equivalents. We adopted this new accounting guidance retrospectively and modified the line item descriptions on our consolidated balance sheets and statements of cash flows in our consolidated financial statements. The other impacts from this new accounting guidance did not have a significant impact on our consolidated financial statements or disclosures. On January 1, 2018, we adopted new accounting 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. We adopted this new accounting guidance using the modified retrospective method, which did not have any significant impact on our consolidated financial statements or disclosures at adoption. On January 1, 2018, we adopted new accounting guidance related to the classification of certain cash payments and cash receipts on our statement of cash flows. The guidance reduces diversity in practice related to eight specific cash flow issues. We adopted this new accounting guidance retrospectively. We will reclassify a $20 million make-whole premium that was incurred in the first quarter of 2016 previously included in the operating activities section of the statement of cash flows, within the line item “other liabilities, policy and contract claims and other policy-related balances” to the financing activities section within the line item “repayment and repurchase of long-term debt” in our 2018 annual consolidated financial statements filed on Form 10-K. On January 1, 2018, we adopted new accounting guidance related to the recognition and measurement of financial assets and financial liabilities. Changes to 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, are measured at fair value with changes in fair value recognized in net income. The new guidance also clarifies that the need for a valuation allowance on a deferred tax asset related to available-for-sale On January 1, 2018, we adopted new accounting guidance related to revenue from contracts with customers. The key principle of the new guidance is that entities should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for such goods or services. Insurance contracts are specifically excluded from this new guidance. The Financial Accounting Standards Board (“the FASB”) has clarified the scope that all of our insurance contracts, including mortgage insurance and investment contracts are excluded from the scope of this new guidance. We adopted this new accounting guidance using the modified retrospective method, which did not have any significant impact on our consolidated financial statements at adoption. Accounting Pronouncements Not Yet Adopted In June 2018, the FASB issued new guidance related to accounting for nonemployee share-based payments. The guidance aligns the measurement and classification of share-based payments to nonemployees issued in exchange for goods or services with the guidance for share-based payments to employees, with certain exceptions. The guidance is currently effective for us on January 1, 2019 using the modified retrospective method, with early adoption permitted. While we are still evaluating the full impact, at this time we do not expect any impacts from this new guidance on our consolidated financial statements. In March 2017, the FASB issued new guidance shortening the amortization period of certain callable debt securities held 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 using the modified retrospective method, with early adoption permitted. While we are still evaluating the full impact, at this time we do not expect any significant impact from this guidance on our consolidated financial statements. In June 2016, the FASB issued new guidance related to accounting for credit losses on financial instruments. The guidance requires that entities recognize an allowance equal to its estimate of lifetime expected credit losses and applies to most debt instruments not measured at fair value, which would primarily include our commercial mortgage loans and reinsurance receivables. The new guidance retains most of the existing impairment guidance for available-for-sale In February 2016, the FASB issued new accounting guidance related to the accounting for leases. The new guidance generally requires lessees to recognize both a right-to-use

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 June 30, 2018 and 2017 was $640 million and $228 million, respectively, which was approximately 97% and 95%, respectively, of book value. The aggregate fair value of securities sold at a loss during the six months ended June 30, 2018 and 2017 was $1,259 million and $1,104 million, respectively, which was approximately 97% and 96%, respectively, of book value.

As of June 30, 2018, our commercial mortgage loans greater than 90 days past due included an impaired loan. This loan had an appraised value in excess of the recorded investment and the current recorded investment of this loan is expected to be recoverable. During the six months ended June 30, 2018 and the year ended December 31, 2017, we modified or extended two and ten commercial mortgage loans, respectively, with a total carrying value of $12 million and $27 million, respectively. All of these modifications or extensions were based on current market interest rates and did not result in any forgiveness in the outstanding principal amount owed by the borrower.

As of June 30, 2017, we had no individually impaired commercial mortgage loans. In evaluating the credit quality of commercial mortgage loans, we assess the performance of the underlying loans using both quantitative and qualitative criteria.

(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) Limited Partnerships or Similar Entities Limited partnerships are accounted for at fair value when our partnership interest is considered minor (generally less than 3% ownership in the limited partnerships) and we exercise no influence over operating and financial policies. If our ownership percentage exceeds that threshold, limited partnerships are accounted for using the equity method of accounting. In applying either method, we use financial information provided by the investee generally on a one-to-three 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. For derivatives that meet the accounting requirements to be designated as hedges, the following disclosures for these derivatives are denoted as “derivatives designated as hedges,” which include both cash flow and fair value hedges. 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 June 30, December 31, Derivatives designated as hedges Cash flow hedges: Interest rate swaps Other invested assets $ 49 $ 74 Other liabilities $ 71 $ 25 Foreign currency swaps Other invested assets 2 1 Other liabilities 1 — Total cash flow hedges 51 75 72 25 Total derivatives designated as hedges 51 75 72 25 Derivatives not designated as hedges Interest rate caps and floors Other invested assets 1 — Other liabilities — — Foreign currency swaps Other invested assets 1 11 Other liabilities 8 — Equity index options Other invested assets 70 80 Other liabilities — — Financial futures Other invested assets — — Other liabilities — — Equity return swaps Other invested assets 1 — Other liabilities — 2 Other foreign currency contracts Other invested assets 106 110 Other liabilities 23 20 GMWB embedded derivatives Reinsurance recoverable (1) 12 14 Policyholder account balances (2) 235 250 Fixed index annuity embedded derivatives Other assets — — Policyholder account balances (3) 420 419 Indexed universal life embedded derivatives Reinsurance recoverable — — Policyholder account balances (4) 13 14 Total derivatives not designated as hedges 191 215 699 705 Total derivatives $ 242 $ 290 $ 771 $ 730 (1) Represents embedded derivatives associated with the reinsured portion of our guaranteed minimum withdrawal benefits (“GMWB”) liabilities.

(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 received 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 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.

Of this amount, $104 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, 2018, we reclassified $5 million 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 non-functional We also had, prior to the fourth quarter of 2017, 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 had recourse to the securitization entity. The interest rate swaps used for these entities were 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 were utilized in certain securitization entities to enhance the yield payable on the borrowings issued by the securitization entity and also included 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.

(2) Included $1 million of accrual on derivatives classified as other liabilities as of June 30, 2018. Does not include amounts related to embedded derivatives and derivatives related to securitization entities as of June 30, 2018 and December 31, 2017. (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, several 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. Beginning in 2018, we have renegotiated with many of our counterparties to remove the credit downgrade provisions from the master swap agreements. If the provisions defined in these agreements had been triggered as of June 30, 2018 and December 31, 2017, we could have been allowed to claim $71 million and $85 million, respectively, or have been required to disburse up to $1 million as of June 30, 2018. The chart above excludes embedded derivatives and derivatives related to securitization entities as those derivatives are not subject to master netting arrangements. We actively responded to the risk in our derivatives portfolio arising from our counterparties’ right to terminate their bilateral over-the-counter Credit Derivatives We sell protection under single name credit default swaps in combination with purchasing a security to replicate characteristics of similar investments based on the credit quality and term of the credit default swap. Credit default triggers for 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. The following table sets forth our credit default swaps where we sell protection on single name reference entities and the fair values as of the dates indicated: June 30, 2018 December 31, 2017 (Amounts in millions) Notional Assets Liabilities Notional Assets Liabilities Investment grade Matures in less than one year $ 20 $ — $ — $ 39 $ — $ — Total credit default swaps on single name reference entities $ 20 $ — $ — $ 39 $ — $ —

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. Apart from certain of our borrowings and certain marketable securities, few of the instruments 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 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, 2018 Notional amount Carrying amount Fair value (Amounts in millions) Total Level 1 Level 2 Level 3 Assets: Commercial mortgage loans $ (1) $ 6,480 $ 6,514 $ — $ — $ 6,514 Restricted commercial mortgage loans (1) 90 96 — — 96 Other invested assets (1) 151 151 — — 151 Liabilities: Long-term borrowings (1) 4,047 3,727 — 3,577 150 Non-recourse (1) 310 209 — — 209 Borrowings related to securitization entities (1) 28 28 — 28 — Investment contracts (1) 13,757 14,007 — — 14,007 Other firm commitments: Commitments to fund limited partnerships 402 — — — — — Commitments to fund bank loan investments 30 — — — — — Ordinary course of business lending 119 — — — — — December 31, 2017 Notional amount Carrying amount Fair value (Amounts in millions) Total Level 1 Level 2 Level 3 Assets: Commercial mortgage loans $ (1) $ 6,341 $ 6,573 $ — $ — $ 6,573 Restricted commercial mortgage loans (1) 107 116 — — 116 Other invested assets (1) 277 299 — — 299 Liabilities: Long-term borrowings (1) 4,224 3,725 — 3,566 159 Non-recourse (1) 310 201 — — 201 Borrowings related to securitization entities (1) 40 41 — 41 — Investment contracts (1) 14,700 15,123 — 5 15,118 Other firm commitments: Commitments to fund limited partnerships 317 — — — — — Commitments to fund bank loan investments 18 — — — — — Ordinary course of business lending 168 — — — — — (1) These financial instruments do not have notional amounts. Recurring Fair Value Measurements We have fixed maturity, short-term investments, equity securities, limited partnerships, 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. Limited partnerships Limited partnerships are valued based on comparable market transactions, discounted future cash flows, quoted market prices and/or estimates using the most recent data available for the underlying instrument. We utilize the net asset value (“NAV”) of the underlying fund statements as a practical expedient for fair value. Fixed maturity, short-term investments and equity securities The fair value of fixed maturity, short-term investments and equity 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. 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. If prices are unavailable from public pricing services we obtain broker quotes. 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 for our fixed maturity, short-term investments and equity 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. Short-term investments. Separate account assets. 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 June 30, 2018: (Amounts in millions) Fair value Primary methodologies Significant inputs U.S. government, agencies and government-sponsored enterprises $ 5,353 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 $ 2,803 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. $ 2,364 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 $ 24,571 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. $ 10,049 Multi-dimensional attribute-based modeling systems, OAS-based Benchmark yields, trade prices, broker quotes, comparative transactions, issuer spreads, bid-offer Residential mortgage-backed $ 3,533 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 $ 3,305 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 $ 2,791 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 The fair value of short-term investments classified as Level 2 is determined 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 caps and floors. 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 April 1, Total realized and Purchases Sales Issuances Settlements Transfer into (1) Transfer out of (1) Ending June 30, Total gains to assets Included in Included Fixed maturity securities: State and political subdivisions $ 53 $ — $ (1 ) $ — $ — $ — $ — $ — $ — $ 52 $ — U.S. corporate: Utilities 553 (1 ) (7 ) 66 (12 ) — (2 ) 25 — 622 — Energy 146 — — — — — (1 ) — (7 ) 138 — Finance and insurance 580 — (41 ) — — — (74 ) — (7 ) 458 — Consumer—non-cyclical 79 — — — — — — — — 79 — Technology and 25 — 1 4 — — (18 ) — — 12 — Industrial 39 — 1 — — — — — — 40 — Capital goods 103 — (1 ) 24 — — — — (7 ) 119 — Consumer—cyclical 252 — (1 ) 7 (3 ) — (1 ) — — 254 — Transportation 57 — — — — — (1 ) — — 56 — Other 166 — — — (10 ) — (3 ) — — 153 — Total U.S. corporate 2,000 (1 ) (48 ) 101 (25 ) — (100 ) 25 (21 ) 1,931 — Non-U.S. Utilities 336 — (4 ) — — — — 15 (14 ) 333 — Energy 195 — (2 ) — — — (18 ) — — 175 — Finance and insurance 153 1 (3 ) 1 — — (1 ) — (1 ) 150 1 Consumer—non-cyclical 120 — (1 ) — — — (11 ) — — 108 — Technology and 28 — 1 — — — (13 ) — — 16 — Industrial 108 — (1 ) 3 — — (5 ) — — 105 — Capital goods 186 1 — — — — (21 ) — — 166 1 Consumer—cyclical 52 — — — (1 ) — (3 ) — — 48 — Transportation 166 — (2 ) 22 — — — 17 — 203 — Other 83 — (1 ) — — — — — — 82 — Total non-U.S. 1,427 2 (13 ) 26 (1 ) — (72 ) 32 (15 ) 1,386 2 Residential mortgage-backed 34 — 1 17 — — (1 ) — (17 ) 34 — Commercial mortgage-backed 6 — — 28 — — — 13 (3 ) 44 — Other asset-backed 172 — (1 ) 6 — — (24 ) 45 (32 ) 166 — Total fixed maturity securities 3,692 1 (62 ) 178 (26 ) — (197 ) 115 (88 ) 3,613 2 Equity securities 45 — — 1 — — — — — 46 — Other invested assets: Derivative assets: Equity index options 60 8 — 15 — — (13 ) — — 70 8 Total derivative assets 60 8 — 15 — — (13 ) — — 70 8 Total other invested assets 60 8 — 15 — — (13 ) — — 70 8 Reinsurance recoverable (2) 13 (1 ) — — — — — — — 12 (1 ) Total Level 3 assets $ 3,810 $ 8 $ (62 ) $ 194 $ (26 ) $ — $ (210 ) $ 115 $ (88 ) $ 3,741 $ 9 (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.

Liability for Policy and Contract Claims	(7) 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 (Amounts in millions) 2018 2017 Beginning balance $ 9,594 $ 9,256 Less reinsurance recoverables (2,419 ) (2,409 ) Net beginning balance 7,175 6,847 Incurred related to insured events of: Current year 1,946 1,804 Prior years (244 ) (244 ) Total incurred 1,702 1,560 Paid related to insured events of: Current year (434 ) (450 ) Prior years (1,266 ) (1,224 ) Total paid (1,700 ) (1,674 ) Interest on liability for policy and contract claims 163 147 Foreign currency translation (16 ) 18 Net ending balance 7,324 6,898 Add reinsurance recoverables 2,341 2,341 Ending balance $ 9,665 $ 9,239 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. For the six months ended June 30, 2018 and 2017, the favorable development of $244 million for both years related to insured events of prior years was primarily attributable to favorable claim terminations, including pending claims that terminate before becoming an active claim, in our long-term care insurance business. The favorable development for the six months ended June 30, 2018 and 2017, was also impacted by our mortgage insurance businesses, primarily from an improvement in net cures and aging of existing claims, including a favorable reserve adjustment of $26 million in our U.S. mortgage insurance business during the second quarter of 2018.

Genworth Holdings On May 22, 2018, Genworth Holdings redeemed $597 million of its 6.52% senior notes that were issued in May 2008 and matured in May 2018. A cash payment of $616 million comprised of net proceeds of $441 million from the senior secured term loan facility (“Term Loan”), as described below, and $175 million of existing cash on hand was used to fully redeem the principal and accrued interest balance of the May 2018 senior notes. On March 7, 2018, Genworth Holdings entered into a $450 million Term Loan, which matures in March 2023 and was issued at a 0.5% discount. Principal payments under the agreement are due quarterly, commencing on June 30, 2018, and are payable in equal amounts of 0.25% per quarter of the original principal amount with the remaining balance due at maturity. At our option, the Term Loan will bear interest at either an adjusted London Interbank Offered Rate (“LIBOR”) no lower than 1.0% plus a margin of 4.5% per annum or an alternate base rate plus a margin of 3.5% per annum. The interest rate on the Term Loan as of June 30, 2018 was 6.5%. We incurred $7 million of borrowing costs that were deferred. The Term Loan is unconditionally guaranteed by Genworth Financial, and Genworth Financial International Holdings, LLC (“GFIH”) has provided a limited recourse guarantee to the lenders of Genworth Holdings’ outstanding Term Loan, which is secured by GFIH’s ownership interest in Genworth Canada’s outstanding common shares. GFIH is our indirect wholly-owned subsidiary and owns approximately 40.5% of the outstanding common stock of Genworth Canada. The Term Loan is subject to other terms and conditions, including but not limited to: voluntary prepayments subject to prepayment penalties, mandatory prepayments in the event of certain asset sales or the incurrence of further indebtedness by Genworth Financial and various financial covenants.

Income Taxes

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 Six months ended 2018 2017 2018 2017 Statutory U.S. federal income tax rate 21.0 % 35.0 % 21.0 % 35.0 % Increase (reduction) in rate resulting from: TCJA, impact from change in tax rate 5.4 — 3.3 — Swaps terminated prior to the TCJA 3.9 — 3.2 — Effect of foreign operations 3.4 (2.0 ) 3.2 (1.0 ) Valuation allowance (2.0 ) — (1.3 ) — Provision to return adjustments (1.6 ) — (0.7 ) — Other, net 0.7 (0.5 ) 0.9 (0.4 ) Effective rate 30.8 % 32.5 % 29.6 % 33.6 % The decrease in the effective tax rate for the three and six months ended June 30, 2018 was primarily attributable to the enactment of the TCJA, which includes a change in the U.S. corporate federal income tax rate from 35% to 21%. This decrease was partially offset by the effect of foreign operations, which had an overall increase on the effective tax rate as our primary foreign subsidiaries are now in jurisdictions with higher statutory tax rates than the United States. The decrease was also partially offset by tax expense in our long-term care insurance business related to gains on forward starting swaps settled prior to the enactment of the TCJA, which are tax effected at 35% as they are amortized into net investment income and from a provisional tax expense of $19 million in the current year related to a revaluation of deferred tax assets and liabilities on our foreign subsidiaries in light of the TCJA. As of December 31, 2017, as prescribed by the SEC’s Staff Accounting Bulletin (“SAB”) 118, we recorded provisional estimates of the tax impact of certain changes in tax law under the TCJA. However, for other changes in the tax law where we were unable to record a reasonable estimate, no amounts were recorded. As of June 30, 2018, we are still in the process of completing the accounting of our provisional estimates and refining our computations as follows: Deferred tax assets and liabilities We recorded a provisional tax benefit of $154 million in 2017 related to remeasurement of certain deferred tax assets and liabilities as a result of the newly enacted tax rate. The Internal Revenue Service has indicated that additional guidance will be forthcoming with respect to several technical areas within the TCJA, which could affect the measurement of these balances or potentially give rise to new deferred tax amounts. During the three months ended June 30, 2018, we recorded a provisional tax expense of $19 million related to a revaluation of deferred tax assets and liabilities on our foreign subsidiaries in light of the TCJA. This amount is considered provisional and additional refinements to the calculation may be required. Foreign tax effects We recorded a provisional tax expense of $63 million in 2017 related to the one-time Insurance reserve transition adjustment We recorded a provisional reclassification in deferred tax assets and liabilities in the amount of $134 million in 2017 related to the transition adjustment required under the TCJA with respect to life insurance policyholder reserves. We continue to refine our insurance reserve calculations and apply the new reserving rules under the TCJA on a product level basis. During the six months ended June 30, 2018, we updated our provisional estimate and identified a measurement period increase to this reclassification of $40 million which has been reflected in our consolidated balance sheet as of June 30, 2018. This measurement period adjustment had no impact on net income, and we will continue to refine this estimate throughout the measurement period. As of June 30, 2018, we are still in the process of completing the accounting for the following areas for which a reasonable estimate could not be made. Foreign tax effects We are still in the process of analyzing the impact of the Global Intangible Low Taxed Income (“GILTI”) and Base Erosion Anti-Abuse Tax (“BEAT”), including accounting policy elections. During the six months ended June 30, 2018, we have included the current tax effects of GILTI and BEAT taxes in current year earnings, but we have not yet made a policy election with respect to the accounting for the potential deferred tax effects of the GILTI tax and no measurement period adjustment has been recorded. State tax effects We have not analyzed certain areas of state income taxes, including the treatment of the one-time Further regulatory guidance related to the TCJA is expected to be issued in 2018 which may result in changes to our current estimates. Any revisions to the estimated impacts of the TCJA will be recorded quarterly until the computations are complete which is expected no later than the fourth quarter of 2018.

Segment Information

Segment Information	6 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 On December 22, 2017, the TCJA was signed into law. The TCJA reduced the U.S. corporate federal income tax rate to 21% effective for taxable years beginning on January 1, 2018 and migrated the worldwide tax system to a territorial international tax system. Therefore, beginning on January 1, 2018 we taxed our international businesses at their local statutory tax rates and our domestic businesses at the new enacted tax rate of 21%. We allocate our consolidated provision for income taxes to our operating segments. Our allocation methodology applies a specific tax rate to the pre-tax 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 (loss) 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 (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. Beginning in the first quarter of 2018, we assumed a tax rate of 21% on certain adjustments to reconcile net income available to Genworth Financial, Inc.’s common stockholders and adjusted operating income available to Genworth Financial, Inc.’s common stockholders (unless otherwise indicated). In the prior year, we assumed a tax rate of 35%, the previous U.S. corporate federal income tax rate prior to the enactment of the TCJA, on certain adjustments to reconcile net income available to Genworth Financial, Inc.’s common stockholders and adjusted operating income available to Genworth Financial, Inc.’s common stockholders. These adjustments are also net of the portion attributable to noncontrolling interests and net investment gains (losses) are adjusted for DAC and other intangible amortization and certain benefit reserves.

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, 2017, in accordance with applicable dividend restrictions, our subsidiaries could pay dividends of approximately $500 million to us in 2018 without obtaining regulatory approval, and the remaining net assets are considered restricted. While the $500 million is unrestricted, our insurance subsidiaries may not pay dividends to us in 2018 at this level if they need to retain capital for growth and to meet capital requirements and desired thresholds. As of June 30, 2018, Genworth Financial’s and Genworth Holdings’ subsidiaries had restricted net assets of $12.6 billion and $11.9 billion, respectively.

Accounting Changes (Policies)

Accounting Changes (Policies)	6 Months Ended
	Jun. 30, 2018
Accounting Pronouncements Recently Adopted	Accounting Pronouncements Recently Adopted On January 1, 2018, we early adopted new accounting guidance on the reclassification from accumulated other comprehensive income to retained earnings for stranded tax effects resulting from the Tax Cuts and Jobs Act (“TCJA”), or “stranded tax effects.” Under current U.S. GAAP, deferred tax assets and liabilities are adjusted for the effect of a change in tax laws or rates with the effect included in income from continuing operations in the period that the changes were enacted. This also includes situations in which the related tax effects were originally recognized in other comprehensive income as opposed to income from continuing operations. The following summarizes the components for the cumulative effect adjustment recorded on January 1, 2018 related to the adoption of this new accounting guidance: Accumulated other comprehensive income (loss) (Amounts in millions) Net unrealized Derivatives Foreign currency Retained Total Deferred taxes: Net unrealized gains on investment securities $ 192 $ — $ — $ (192 ) $ — Net unrealized gains on derivatives — 12 — (12 ) — Investment in foreign subsidiaries (3 ) — (46 ) 49 — Accrued commission and general expenses — — (1 ) 1 — Cumulative effect of changes in accounting $ 189 $ 12 $ (47 ) $ (154 ) $ — The accounting for the temporary differences related to investment in foreign subsidiaries recorded in accumulated other comprehensive income (loss) at adoption of the TCJA, were provisional. Therefore, additional reclassification adjustments may be recorded in future periods as tax effects of the TCJA on related temporary differences are finalized. However, no reclassification adjustments were recorded in the second quarter of 2018. Other than those effects related to the TCJA, our policy is to release stranded tax effects from accumulated other comprehensive income (loss) using the portfolio approach for items related to investments and derivatives, and upon disposition of a subsidiary for items related to outside basis differences. On January 1, 2018, we early adopted new accounting guidance related to the hedge accounting model. The new guidance amends the hedge accounting model 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 and removed the requirements to separately measure and report hedge ineffectiveness. We adopted this new accounting using the modified retrospective method and recognized a gain of $2 million in accumulated other comprehensive income with a corresponding decrease to retained earnings at adoption. This gain was the cumulative amount of hedge ineffectiveness related to active hedges that was previously included in earnings. On January 1, 2018, we adopted new accounting guidance that clarifies 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. We adopted this new accounting guidance prospectively and therefore, the guidance did not have any impact at adoption. On January 1, 2018, we adopted new accounting guidance that clarifies the scope and accounting for gains and losses from the derecognition of nonfinancial assets or an in substance nonfinancial asset that is not a business 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. We adopted this new accounting guidance using the modified retrospective method, which had no impact on our consolidated financial statements at adoption. On January 1, 2018, we early adopted new accounting 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. We adopted this new accounting guidance prospectively and will apply it to our 2018 goodwill impairment test. On January 1, 2018, we adopted new accounting guidance related to the classification and presentation of changes in restricted cash. The new guidance requires that changes in the total of cash, cash equivalents, restricted cash and restricted cash equivalents be shown in the statements of cash flows and requires additional disclosures related to restricted cash and restricted cash equivalents. We adopted this new accounting guidance retrospectively and modified the line item descriptions on our consolidated balance sheets and statements of cash flows in our consolidated financial statements. The other impacts from this new accounting guidance did not have a significant impact on our consolidated financial statements or disclosures. On January 1, 2018, we adopted new accounting 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. We adopted this new accounting guidance using the modified retrospective method, which did not have any significant impact on our consolidated financial statements or disclosures at adoption. On January 1, 2018, we adopted new accounting guidance related to the classification of certain cash payments and cash receipts on our statement of cash flows. The guidance reduces diversity in practice related to eight specific cash flow issues. We adopted this new accounting guidance retrospectively. We will reclassify a $20 million make-whole premium that was incurred in the first quarter of 2016 previously included in the operating activities section of the statement of cash flows, within the line item “other liabilities, policy and contract claims and other policy-related balances” to the financing activities section within the line item “repayment and repurchase of long-term debt” in our 2018 annual consolidated financial statements filed on Form 10-K. On January 1, 2018, we adopted new accounting guidance related to the recognition and measurement of financial assets and financial liabilities. Changes to 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, are measured at fair value with changes in fair value recognized in net income. The new guidance also clarifies that the need for a valuation allowance on a deferred tax asset related to available-for-sale On January 1, 2018, we adopted new accounting guidance related to revenue from contracts with customers. The key principle of the new guidance is that entities should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for such goods or services. Insurance contracts are specifically excluded from this new guidance. The Financial Accounting Standards Board (“the FASB”) has clarified the scope that all of our insurance contracts, including mortgage insurance and investment contracts are excluded from the scope of this new guidance. We adopted this new accounting guidance using the modified retrospective method, which did not have any significant impact on our consolidated financial statements at adoption.
Accounting Pronouncements Not Yet Adopted	Accounting Pronouncements Not Yet Adopted In June 2018, the FASB issued new guidance related to accounting for nonemployee share-based payments. The guidance aligns the measurement and classification of share-based payments to nonemployees issued in exchange for goods or services with the guidance for share-based payments to employees, with certain exceptions. The guidance is currently effective for us on January 1, 2019 using the modified retrospective method, with early adoption permitted. While we are still evaluating the full impact, at this time we do not expect any impacts from this new guidance on our consolidated financial statements. In March 2017, the FASB issued new guidance shortening the amortization period of certain callable debt securities held 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 using the modified retrospective method, with early adoption permitted. While we are still evaluating the full impact, at this time we do not expect any significant impact from this guidance on our consolidated financial statements. In June 2016, the FASB issued new guidance related to accounting for credit losses on financial instruments. The guidance requires that entities recognize an allowance equal to its estimate of lifetime expected credit losses and applies to most debt instruments not measured at fair value, which would primarily include our commercial mortgage loans and reinsurance receivables. The new guidance retains most of the existing impairment guidance for available-for-sale In February 2016, the FASB issued new accounting guidance related to the accounting for leases. The new guidance generally requires lessees to recognize both a right-to-use
