Therefore, as a result of our loss from continuing operations available to Genworth Financial, Inc.’s common stockholders for the three months ended March 31, 2020, we were required to use basic weighted-average common shares outstanding as the inclusion of shares for stock options, restricted stock units and stock appreciation rights of 5.4 million 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 ended March 31, 2020, dilutive potential weighted-average common shares outstanding would have been 509.7 million.

Organization, Consolidation and Presentation of Financial Statements [Abstract]
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. 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 Financial,” “Genworth,” the “Company,” “we” or “our” in the accompanying unaudited condensed consolidated financial statements and the notes thereto are, unless the context otherwise requires, to Genworth Financial, Inc. on a consolidated basis. We operate our business through the following three operating segments: • U.S. Mortgage Insurance. • U.S. Life Insurance. • Runoff. In addition to our three 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 international mortgage insurance businesses and discontinued operations. On March 3, 2021, we completed a sale of our entire ownership interest of approximately 52% in Genworth Mortgage Insurance Australia Limited (“Genworth Australia”) through an underwritten agreement. We sold our approximately 214.3 million shares of Genworth Australia for AUD2.28 per share. Our Australian mortgage insurance business, previously the primary business in the Australia Mortgage Insurance segment, is reported as discontinued operations and its financial position, results of operations and cash flows are separately reported for all periods presented. All prior periods reflected herein have been re-presented on this basis. See note 14 for additional information. Unless otherwise indicated, references to the condensed consolidated balance sheets, the condensed consolidated statements of income, the condensed consolidated statements of cash flows and the notes to the condensed consolidated financial statements, exclude amounts related to discontinued operations. The accompanying condensed consolidated financial statements are unaudited and have been prepared in accordance with U.S. generally accepted accounting principles (“U.S. GAAP”) and rules and regulations of the U.S. Securities and Exchange Commission (“SEC”). Preparing financial statements in conformity with U.S. GAAP requires us to make estimates and assumptions that affect reported amounts and related disclosures. Actual results could differ from those estimates. These 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 2020 Annual Report on Form 10-K. Certain prior year amounts have been reclassified to conform to the current year presentation. Each reporting period, we assess our ability to continue as a going concern for one year from the date the financial statements are issued. As of March 31, 2021, Genworth Holdings has $697 million of unrestricted cash and cash equivalents. Our evaluation of our ability to meet our financial obligations included the following contractual obligations due within one year from the issue date of our unaudited condensed consolidated financial statements included herein, as well as other conditions and events and their relative significance in relation to our ability to meet our obligations: • As of March 31, 2021, Genworth Holdings has outstanding $514 million of its 7.625% senior notes that mature in September 2021. We are currently in compliance with the terms of our debt agreements and interest payments on our senior notes are forecasted to be $101 million for the next twelve months. See note 8 for additional details on our long-term borrowings. • As part of the settlement agreement reached in July 2020 regarding the case titled AXA S.A. v. Genworth Financial International Holdings, LLC et al., • Genworth Holdings received in the first quarter of 2021 intercompany cash tax payments generated primarily from taxable income on investment gains and is expecting additional intercompany cash tax payments in future periods. • Until the secured promissory note to AXA is paid, annual dividends above $50 million from our U.S. mortgage insurance subsidiary are subject to mandatory prepayment conditions. We received net cash proceeds of $370 million from the sale of Genworth Australia in March 2021, of which $247 million was used to prepay a portion of the AXA promissory note, as noted above, including accrued interest. The remaining proceeds, along with Genworth Holdings’ unrestricted cash and cash equivalents, provide sufficient liquidity to meet our financial obligations and maintain business operations for one year from the date the financial statements are issued, based on relevant conditions and events that are known and reasonably estimable, including current cash and management actions in the normal course. Accordingly, we no longer need to determine whether our plans alleviate doubt about our ability to meet our financial commitments and obligations within the next year. The remaining AXA promissory note, including expected future claims, is estimated to be $343 million and is due in sale of our U.S. mortgage insurance business, subject to market conditions, as well as the satisfication of various conditions and approvals. The impact of the ongoing coronavirus pandemic (“COVID-19”) is very difficult to predict. Its related outcomes and impact on our business and the capital markets, and our ability to raise capital will depend on economic impacts from social, global and political influences as a result of the pandemic, and the shape of the economic recovery, among other factors and uncertainties. While these risks exist, we believe our current liquidity is sufficient to meet our obligations for one year following the issuance of our unaudited condensed consolidated financial statements.

Accounting Changes

Disclosue of Accounting Changes [Abstract]
Accounting Changes	(2) Accounting Changes Accounting Pronouncements Recently Adopted On January 1, 2021, we adopted new accounting guidance related to simplifying the accounting for income taxes. The guidance eliminates certain exceptions related to the approach for intraperiod tax allocation, the methodology for calculating income taxes in an interim period and the recognition of deferred tax liabilities for outside basis differences. We adopted this new accounting guidance using the retrospective method or modified retrospective method for certain changes and prospective method for all other changes, which did not have a significant impact on our consolidated financial statements and disclosures. Accounting Pronouncements Not Yet Adopted In August 2018, the Financial Accounting Standards Board (the “FASB”) issued new accounting guidance that significantly changes the recognition and measurement of long-duration insurance contracts and expands disclosure requirements, which impacts our life insurance deferred acquisition costs (“DAC”) and liabilities. In accordance with the guidance, the more significant changes include: • assumptions will no longer be locked-in at contract inception and all cash flow assumptions used to estimate the liability for future policy benefits (except the discount rate) will be reviewed at least annually in the same period each year or more frequently if actual experience indicates a change is required. Changes will be recorded in net income (loss) using a retrospective approach with a cumulative catch-up adjustment by recalculating the net premium ratio (which will be capped at 100%) using actual historical and updated future cash flow assumptions; • the discount rate used to determine the liability for future policy benefits will be a current upper-medium grade (low credit risk) fixed-income instrument yield, which is generally interpreted to mean a single-A rated bond rate for the same duration, and is required to be reviewed quarterly, with changes in the discount rate recorded in other comprehensive income (loss); • the provision for adverse deviation and the premium deficiency test will be eliminated; • market risk benefits associated with deposit-type contracts will be measured at fair value with changes related to instrument-specific credit risk recorded in other comprehensive income (loss) and remaining changes recorded in net income (loss); • the amortization method for DAC will generally be on a straight-line basis over the expected contract term; and • disclosures will be greatly expanded to include significant assumptions and product liability rollforwards. This guidance is effective for us on January 1, 2023 using the modified retrospective method for all topics except for market risk benefits, which is required to be applied using the retrospective method, with early adoption permitted, which we do not intend to elect. Given the nature and extent of the changes to our operations, this guidance is expected to have a significant impact on our consolidated financial statements.

Therefore, as a result of our loss from continuing operations available to Genworth Financial, Inc.’s common stockholders for the three months ended March 31, 2020, we were required to use basic weighted-average common shares outstanding as the inclusion of shares for stock options, restricted stock units and stock appreciation rights of 5.4 million 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 ended March 31, 2020, dilutive potential weighted-average common shares outstanding would have been 509.7 million.

loss position included in the tables above. Based on a qualitative and quantitative review of the issuers of the securities, we believe the decline in fair value is largely due to recent market volatility and is not indicative of credit losses. The issuers continue to make timely principal and interest payments. For all securities in an unrealized loss position without an allowance for credit losses, we expect to recover the amortized cost based on our estimate of the amount and timing of cash flows to be collected. We do not intend to sell nor do we expect that we will be required to sell these securities prior to recovering our amortized cost.

No other industry group comprised more than 10% of our investment portfolio. As of March 31, 2021, we did not hold any fixed maturity securities in any single issuer, other than securities issued or guaranteed by the U.S. government, which exceeded 10% of stockholders’ equity. (e) Commercial Mortgage Loans Our mortgage loans are collateralized by commercial properties, including multi-family residential buildings. The carrying value of commercial mortgage loans is stated at original cost net of principal payments, amortization and allowance for credit losses. We diversify our commercial mortgage loans by both property type and geographic region.

For a discussion of our policy related to placing commercial mortgage loans on non-accrual status, see Note 2—Summary of Significant Accounting Policies included in the Notes to Consolidated Financial Statements in our 2020 Annual Report on Form 10-K. As of March 31, 2021 and December 31, 2020, we had no commercial mortgage loans on non-accrual status. During the three months ended March 31, 2021 and the year ended December 31, 2020, we did not have any modifications or extensions that were considered troubled debt restructurings. The following table sets forth the allowance for credit losses related to commercial mortgage loans as of or for the periods indicated: Three months ended March 31, (Amounts in millions) 2021 2020 Allowance for credit losses: Beginning balance $ 31 $ 13 Cumulative effect of change in accounting — 16 Provision 1 — Write-offs — — Recoveries — — Ending balance $ 32 $ 29 In evaluating the credit quality of commercial mortgage loans, we assess the performance of the underlying loans using both quantitative and qualitative criteria. Certain risks associated with commercial mortgage loans can be evaluated by reviewing both the debt-to-value and debt service coverage ratio to understand both the probability of the borrower not being able to make the necessary loan payments as well as the ability to sell the underlying property for an amount that would enable us to recover our unpaid principal balance in the event of default by the borrower. The average debt-to-value ratio is based on our most recent estimate of the fair value for the underlying property which is evaluated at least annually and updated more frequently if necessary to better indicate risk associated with the loan. A lower debt-to-value indicates that our loan value is more likely to be recovered in the event of default by the borrower if the property was sold. The debt service coverage ratio is based on “normalized” annual income of the property compared to the payments required under the terms of the loan. Normalization allows for the removal of annual one-time events such as capital expenditures, prepaid or late real estate tax payments or non-recurring third-party fees (such as legal, consulting or contract fees). This ratio is evaluated at least annually and updated more frequently if necessary to better indicate risk associated with the loan. A higher debt service coverage ratio indicates the borrower is less likely to default on the loan. The debt service coverage ratio is not used without considering other factors associated with the borrower, such as the borrower’s liquidity or access to other resources that may result in our expectation that the borrower will continue to make the future scheduled payments.

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 month lag. However, for limited partnerships measured at fair value, we consider whether an adjustment to the estimated fair value is necessary when the measurement date is not aligned with our reporting date. Investments in limited 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 member equity investments in a widely held fund that is sponsored and managed by a reputable asset manager. We are not

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 some 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 cash flow hedges. The following table sets forth our positions in derivative instruments as of the dates indicated: Derivative assets Derivative liabilities Balance Fair value Balance sheet classification Fair value March 31, 2021 December 31, 2020 March 31, 2021 December 31, 2020 (Amounts in millions) Derivatives designated as hedges Cash flow hedges: Interest rate swaps Other invested assets $ 84 $ 468 Other liabilities $ 170 $ 23 Foreign currency swaps Other invested assets — 1 Other liabilities 3 2 Total cash flow hedges 84 469 173 25 Total derivatives designated as hedges 84 469 173 25 Derivatives not designated as hedges Equity index options Other invested assets 53 63 Other liabilities — — Financial futures Other invested assets — — Other liabilities — — Other foreign currency contracts Other invested assets 27 42 Other liabilities — 1 GMWB embedded derivatives Reinsurance (1) 18 26 Policyholder account (2) 272 379 Fixed index annuity embedded derivatives Other assets — — Policyholder account (3) 362 399 Indexed universal life embedded derivatives Reinsurance — — Policyholder (4) 23 26 Total derivatives not designated as hedges 98 131 657 805 Total derivatives $ 182 $ 600 $ 830 $ 830 (1) Represents embedded derivatives associated with the reinsured portion of our guaranteed minimum withdrawal benefits (“GMWB”) 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 embedded derivatives, 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 other comprehensive income (loss) (“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; and (v) other instruments to hedge the cash flows of various forecasted transactions.

Of this amount, $137 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 three months ended March 31, 2021 and 2020, we reclassified $2 million in both periods 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 derivative instruments such as: (i) interest rate swaps and financial futures to mitigate interest rate risk as part of managing regulatory capital positions; (ii) equity index options, equity return swaps, interest rate swaps and financial futures to mitigate the risks associated with liabilities that have guaranteed minimum benefits, fixed index annuities and indexed universal life; and (iii) foreign currency options and forward contracts to mitigate currency risk associated with future dividends, cash payments to AXA under a promissory note reported as discontinued operations and/or other cash flows from certain foreign subsidiaries to our holding company. Additionally, we provide GMWBs on certain variable annuities that are required to be bifurcated as embedded derivatives. We also offer fixed index annuity and indexed universal life insurance products and have reinsurance agreements with certain features that are required to be bifurcated as embedded derivatives.

Fair Value of Financial Instrum

Fair Value of Financial Instruments	3 Months Ended

Fair Value of Financial Instruments	(6) Fair Value of Financial Instruments Recurring Fair Value Measurements We have fixed maturity securities, 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. Fixed maturity, short-term investments and equity securities The fair value of fixed maturity securities, 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, that security is valued using market information for similar securities, which is also a market approach. When market information is not available for a specific security (or similar securities) 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. Further, 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. In general, we first obtain valuations from pricing services. If prices are unavailable for public securities, 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 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 similar securities are not readily observable and these securities are not typically valued by pricing services. Given our understanding of the pricing methodologies and procedures of pricing services, the securities valued by pricing services are typically classified as Level 2 unless we determine the valuation process for a security or group of securities utilizes significant unobservable inputs, which would result in the valuation being classified as Level 3. 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 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. 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. While we generally consider the public bond spreads by sector and maturity to be observable inputs, we evaluate the similarities of our private placement with the public bonds, any price caps utilized, liquidity premiums applied, and whether external ratings are available for our private placements to determine whether the spreads utilized would be considered observable inputs. We classify private securities without an external rating or public bond spread as Level 3. In general, a significant increase (decrease) in credit spreads would have resulted in a significant decrease (increase) in the fair value for our fixed maturity securities as of March 31, 2021. For remaining securities priced using internal models, we determine fair value using an income approach. 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. 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 pricing services to determine whether our estimated values incorporate significant unobservable inputs that would result in the valuation being classified as Level 3. A summary of the inputs used for our fixed maturity securities, 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. 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 pricing services for certain fair value measurements of fixed maturity securities that are classified as Level 2 as of March 31, 2021: (Amounts in millions) Fair value Primary methodologies Significant inputs U.S. government, agencies and government-sponsored enterprises $ 4,273 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 $ 3,067 Multi-dimensional attribute-based modeling systems, third-party pricing vendors Trade prices, material event notices, Municipal Market Data benchmark yields, broker quotes Non-U.S. government $ 820 Matrix pricing, spread priced to benchmark curves, price quotes from market makers Benchmark yields, trade prices, broker quotes, comparative transactions, issuer spreads, bid-offer spread, market research publications, third-party pricing sources U.S. corporate $ 30,480 Multi-dimensional attribute-based modeling systems, broker quotes, price quotes from market makers, OAS-based models Bid side prices to Treasury Curve, Issuer Curve, which includes sector, quality, duration, OAS percentage and change for spread matrix, trade prices, comparative transactions, Trade Reporting and Compliance Engine (“TRACE”) reports Non-U.S. corporate $ 8,160 Multi-dimensional attribute-based modeling systems, OAS-based models, price quotes from market makers Benchmark yields, trade prices, broker quotes, comparative transactions, issuer spreads, bid-offer spread, market research publications, third-party pricing sources Residential mortgage-backed $ 1,761 OAS-based models, single factor binomial models, internally priced Prepayment and default assumptions, aggregation of bonds with similar characteristics, including collateral type, vintage, tranche type, weighted-average life, weighted-average loan age, issuer program and delinquency ratio, pay up and pay down factors, TRACE reports Commercial mortgage-backed $ 2,775 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 $ 2,747 Multi-dimensional attribute-based modeling systems, spread matrix priced to swap curves, price quotes from market makers Spreads to daily updated swap curves, spreads derived from trade prices and broker quotes, bid side prices, new issue data, collateral performance, analysis of prepayment speeds, cash flows, collateral loss analytics, historical issue analysis, trade data from market makers, TRACE reports • Internal models: Equity securities. Securities lending collateral The fair value of securities held as collateral is primarily based on Level 2 inputs from market information for the collateral that is held on our behalf by the custodian. We determine fair value after considering prices obtained by pricing services. Short-term investments The fair value of short-term investments classified as Level 2 is determined after considering prices obtained by pricing services. Level 3 measurements Fixed maturity securities • Broker quotes: • Internal models: Equity securities. Net asset value 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”) from the underlying fund statements as a practical expedient for fair value. Derivatives We consider counterparty collateral arrangements and rights of set-off when evaluating our net credit risk exposure to our derivative counterparties. Accordingly, we are permitted to include consideration of these arrangements when determining whether any incremental adjustment should be made for both the counterparty’s and our non-performance risk in measuring fair value for our derivative instruments. As a result of these counterparty arrangements, we determined that any adjustment for credit risk would not be material and we have not recorded any incremental adjustment for our non-performance risk or the non-performance risk of the derivative counterparty for our derivative assets or liabilities. Interest rate swaps. Foreign currency swaps. Equity index options. Financial futures. Other foreign currency contracts. forward interest rate, foreign currency exchange rate volatility and time value component associated with the optionality in the derivative, which are generally considered observable inputs and results in the derivative being classified as Level 2. We also have foreign currency forward contracts where the valuation is determined using an income approach. The primary inputs into the valuation represent the forward foreign currency exchange rates, which are generally considered observable inputs and results in the derivative being classified as Level 2. GMWB embedded derivatives We are required to bifurcate an embedded derivative for certain features associated with annuity products and related reinsurance agreements where we provide a GMWB to the policyholder and are required to record the GMWB embedded derivative at fair value. The valuation of our GMWB embedded derivative is based on an income approach that incorporates inputs such as forward interest rates, equity index volatility, equity index and fund correlation, and policyholder assumptions such as utilization, lapse and mortality. We determine fair value using an internal model based on the various inputs noted above. Non-performance risk is integrated into the discount rate used to value GMWB liabilities. Our discount rate used to determine fair value of our GMWB liabilities includes market credit spreads above U.S. Treasury rates to reflect an adjustment for the non-performance risk of the GMWB liabilities. As of March 31, 2021 and December 31, 2020, the impact of non-performance risk resulted in a lower fair value of our GMWB liabilities of $50 million and $66 million, respectively. We classify the GMWB valuation as Level 3 based on having significant unobservable inputs, with equity index volatility and non-performance risk being considered the more significant unobservable inputs. As equity index volatility increases, the fair value of the GMWB liabilities will increase. Any increase in non-performance risk would increase the discount rate and would decrease the fair value of the GMWB liability. Additionally, we consider lapse and utilization assumptions to be significant unobservable inputs. An increase in our lapse assumption would decrease the fair value of the GMWB liability, whereas an increase in our utilization rate would increase the fair value. As of March 31, 2021, a significant change in the unobservable inputs discussed above would have resulted in a significantly lower or higher fair value measurement. Fixed index annuity embedded derivatives We have fixed indexed annuity products where interest is credited to the policyholder’s account balance based on equity index changes. This feature is required to be bifurcated as an embedded derivative and recorded at fair value. Fair value is determined using an income approach where the present value of the excess cash flows above the guaranteed cash flows is used to determine the value attributed to the equity index feature. The inputs used in determining the fair value include policyholder behavior (lapses and withdrawals), near-term equity index volatility, expected future interest credited, forward interest rates and an adjustment to the discount rate to incorporate non-performance risk and risk margins. As a result of our assumptions for policyholder behavior and expected future interest credited being considered significant unobservable inputs, we classify these instruments as Level 3. As lapses and withdrawals increase, the value of our embedded derivative liability will decrease. As expected future interest credited decreases, the value of our embedded derivative liability will decrease. As of March 31, 2021, a significant change in the unobservable inputs discussed above would have resulted in a significantly lower or higher fair value measurement. Indexed universal life embedded derivatives We have indexed universal life insurance products where interest is credited to the policyholder’s account balance based on equity index changes. This feature is required to be bifurcated as an embedded derivative and recorded at fair value. Fair value is determined using an income approach where the present value of the excess cash flows above the guaranteed cash flows is used to determine the value attributed to the equity index feature. The inputs used in determining the fair value include policyholder behavior (lapses and withdrawals), near-term equity index volatility, expected future interest credited, forward interest rates and an adjustment to the discount rate to incorporate non-performance risk and risk margins. As a result of our assumptions for policyholder behavior and expected future interest credited being considered significant unobservable inputs, we classify these instruments as Level 3. As lapses and withdrawals increase, the value of our embedded derivative liability will decrease.

Such adjustments, reflecting any variety of new and adverse trends, could 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. In addition, loss reserves recorded on new delinquencies in our U.S. mortgage insurance business have a high degree of estimation, particularly due to the level of uncertainty regarding whether borrowers in forbearance will ultimately cure or result in a claim payment. For the three months ended March 31, 2021, the favorable development of $229 million related to insured events of prior years was primarily attributable to our long-term care insurance business largely from favorable claim terminations mostly attributable to higher mortality, favorable development on prior year incurred but not reported claims and favorable experience on pending claims that did not become an active claim. These decreases were partially offset by higher reserves of $93 million to account for changes to incidence and mortality experience driven by COVID-19,

Segment Information

Segment Information	3 Months Ended
	Mar. 31, 2021
Segment Information	(10) Segment Information We have the following three operating business segments: U.S. 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 tax our businesses at the U.S. corporate federal income tax rate of 21%. Each segment is then adjusted to reflect the unique tax attributes of that segment, such as permanent differences between U.S. GAAP and tax law. The difference between the consolidated provision for income taxes and the sum of the provision for income taxes in each segment is reflected in Corporate and Other activities. The annually-determined tax rates and adjustments to each segment’s provision for income taxes are estimates which are subject to review and could change from year to year. We use the same accounting policies and procedures to measure segment income (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 (losses) on the sale of businesses, gains (losses) on the early extinguishment of debt, gains (losses) on insurance block transactions, restructuring costs and infrequent or unusual non-operating 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.

Commitments and Contingencies

Commitments and Contingencies	3 Months Ended

Commitments and Contingencies	(11) Commitments and Contingencies (a) Litigation and Regulatory Matters We face the risk of litigation and regulatory investigations and actions in the ordinary course of operating our businesses, including the risk of class action lawsuits. Our pending legal and regulatory actions include proceedings specific to us and others generally applicable to business practices in the industries in which we operate. In our insurance operations, we are, have been, or may become subject to class actions and individual suits alleging, among other things, issues relating to sales or underwriting practices, increases to in-force long-term laws, and mortgage insurance policy rescissions and curtailments, and breaching fiduciary or other duties to customers, including but not limited to breach of customer information. Plaintiffs in class action and other lawsuits against us may seek very large or indeterminate amounts which may remain unknown for substantial periods of time. In our investment-related operations, we are subject to litigation involving commercial disputes with counterparties. We are also subject to litigation arising out of our general business activities such as our contractual and employment relationships, post-closing obligations associated with previous dispositions and securities lawsuits. In addition, we are also subject to various regulatory inquiries, such as information requests, subpoenas, books and record examinations and market conduct and financial examinations from state, federal and international regulators and other authorities. A substantial legal liability or a significant regulatory action against us could have an adverse effect on our business, financial condition and results of operations. Moreover, even if we ultimately prevail in the litigation, regulatory action or investigation, we could suffer significant reputational harm, which could have an adverse effect on our business, financial condition or results of operations. In January 2016, Genworth Financial, its current chief executive officer, its former chief executive officer, its then former chief financial officer and current and former members of its board of directors were named in a shareholder derivative suit filed by International Union of Operating Engineers Local No. 478 Pension Fund, Richard L. Salberg and David Pinkoski in the Court of Chancery of the State of Delaware. The case was captioned Int’l Union of Operating Engineers Local No. 478 Pension Fund, et al v. McInerney, et al Cohen v. McInerney, et al Genworth Financial, Inc. Consolidated Derivative Litigation In October 2016, Genworth Financial, its current chie f Chopp v. McInerney, et al transaction. On January 14, 2021, the parties submitted a joint letter to the Court requesting that the action remain stayed until April 15, 2021, or until the closing or termination of the merger in the event the merger closed or was terminated prior to April 15, 2021. On April 6, 2021, Genworth Financial terminated the proposed China Oceanwide transaction, thereby lifting the stay. We intend to vigorously defend this action. In September 2018, Genworth Life and Annuity Insurance Company (“GLAIC”), our indirect wholly-owned subsidiary, was named as a defendant in a putative class action lawsuit pending in the United States District Court for the Eastern District of Virginia captioned TVPX ARX INC., as Securities Intermediary for Consolidated Wealth Management, LTD. on behalf of itself and all others similarly situated v. Genworth Life and Annuity Insurance Company non-mortality In September 2018, Genworth Financial, Genworth Holdings, Genworth North America Corporation, Genworth Financial International Holdings, LLC (“GFIH”) and Genworth Life Insurance Company (“GLIC”) were named as defendants in a putative class action lawsuit pending in the Court of Chancery of the State of Delaware captioned Richard F. Burkhart, William E. Kelly, Richard S. Lavery, Thomas R. Pratt, Gerald Green, individually and on behalf of all other persons similarly situated v. Genworth et al plaintiffs filed a memorandum in opposition to our motion to dismiss, which we replied to on June 14, 2019. On August 7, 2019, plaintiffs filed a motion seeking to prevent proceeds that GFIH expected to receive from the then planned sale of its shares in Genworth MI Canada Inc. (“Genworth Canada”) from being transferred out of GFIH. On September 11, 2019, plaintiffs filed a renewed motion seeking the same relief from their August 7, 2019 motion with an exception that allowed GFIH to transfer $450 million of expected proceeds from the sale of Genworth Canada through a dividend to Genworth Holdings to allow the pay-off On April 6, 2020, GLAIC, our indirect wholly-owned subsidiary, was named as a defendant in a putative class action lawsuit filed in the United States District Court for the Eastern District of Virginia, captioned Brighton Trustees, LLC, on behalf of and as trustee for Diamond LS Trust; and Bank of Utah, solely as securities intermediary for Diamond LS Trust; on behalf of themselves and all others similarly situated v. Genworth Life and Annuity Insurance Company Ronald L. Daubenmier, individually and on behalf of himself and all others similarly situated v. Genworth Life and Annuity Insurance Company In January 2021, GLIC and Genworth Life Insurance Company of New York were named as defendants in a putative class action lawsuit pending in the United States District Court for the Eastern District of Virginia captioned Judy Halcom, Hugh Penson, Harold Cherry, and Richard Landino, individually, and on behalf of all others similarly situated v. Genworth Life Insurance Company and Genworth Life Insurance Company of New York million. The trial is scheduled to commence on June 1, 2022. We intend to vigorously defend this action. In January 2021, GLAIC, our indirect wholly-owned subsidiary, was named as a defendant in a putative class action lawsuit pending in the United States District Court for the District of Oregon captioned Patsy H. McMillan, Individually and On Behalf Of All Others Similarly Situated, v. Genworth Life and Annuity Insurance Company contract, conversion, and declaratory and injunctive relief, and seeks damages in excess of $5 million. On April 5, 2021, we filed an answer to the plaintiff’s complaint. We intend to continue to vigorously defend this action. At this time we cannot determine or predict the ultimate outcome of any of the pending legal and regulatory matters specifically identified above or the likelihood of potential future legal and regulatory matters against us. Except as disclosed above, we are not able to provide an estimate or range of reasonably possible losses related to these matters. Therefore, we cannot ensure that the current investigations and proceedings will not have a material adverse effect on our business, financial condition or results of operations. In addition, it is possible that related investigations and proceedings may be commenced in the future, and we could become subject to additional unrelated investigations and lawsuits. Increased regulatory scrutiny and any resulting investigations or proceedings could result in new legal precedents and industry-wide regulations or practices that could adversely affect our business, financial condition and results of operations. (b) Commitments As of March 31, 2021, we were committed to fund $1,192 million in limited partnership investments, $63 million in U.S. commercial mortgage loan investments and $65 million in private placement investments. As of March 31, 2021, we were also committed to fund $27 million of bank loan investments which had not yet been drawn.

In 2017, AXA sued us for damages on an indemnity in the 2015 agreement related to alleged remediation it paid to customers who purchased payment protection insurance (“PPI”). On July 20, 2020, we reached a settlement agreement related to losses incurred from mis-selling mis-selling The following table presents the amounts owed to AXA under the settlement agreement, which are reflected as liabilities related to discontinued operations in our condensed consolidated balance sheets as of the periods presented: (Amounts in millions) British Pounds U.S. Dollar March 31, December 31, March 31, December 31, 2021 2020 2021 2020 Installment payments due to AXA: June 2022: Beginning balance £ 159 £ 159 $ 217 $ 217 Prepayments (1) (159 ) — (217 ) — Ending balance — 159 — 217 September 2022: Beginning balance 187 158 256 217 Prepayments (1) (17 ) — (28 ) — Amounts billed as future losses 35 29 47 39 Foreign exchange and other — — 8 — Ending balance 205 187 283 256 Total amounts due under the promissory note 205 346 283 473 Future claims: Estimated beginning balance 79 107 108 146 Change in estimated future claims — 1 — 1 Less: Amounts billed (35 ) (29 ) (47 ) (39 ) Foreign exchange and other — — (1 ) — Estimated future billings 44 79 60 108 Total amounts due to AXA under the settlement agreement (2) £ 249 £ 425 $ 343 $ 581 (1) On March 3, 2021, we completed the sale of Genworth Australia and received net proceeds of approximately AUD483 million ($370 million). The sale of Genworth Australia resulted in a mandatory principal payment of approximately £176 million ($245 million) related to our outstanding secured promissory note issued to AXA, dated as of July 20, 2020, as amended by the parties in connection with the Genworth Australia sale. (2) Amounts exclude accrued interest on the promissory note and certain other expenses. As of March 31, 2021, due principally to the mandatory payment made in connection with the Genworth Australia sale, including approximately $2 million of accrued interest, we reduced the amount of accrued interest payable on the promissory note resulting in a reduction in the total amount owed to AXA of approximately $4 million. An after-tax after-tax To secure our obligation under the amended promissory note, we granted a 19.9% security interest in the outstanding common stock of GMHI to AXA. AXA does not have the right to sell or repledge the collateral and is not entitled to any voting rights. The collateral will be released back to us upon full repayment of the promissory note. Accordingly, the collateral arrangement has no impact on our consolidated financial statements. In the event AXA recovers amounts from third parties related to the mis-selling mis-selling The promissory note is also subject to certain mandatory prepayments upon the occurrence of: • the consummation of certain qualifying debt transactions in which total gross proceeds of at least $750 million are raised; • the consummation of certain qualifying equity issuances or dispositions with respect to GMHI, or any of our subsidiaries, in which total net cash proceeds of at least $475 million are raised; • certain dispositions of our U.S. mortgage insurance business; • transactions involving a change of control of Genworth; and • receipt of dividends and sale proceeds from GMHI above certain threshold amounts. The promissory note also contains certain negative and affirmative covenants, restrictions imposed on the collateral, representations and warranties and customary events of default. In addition to the promissory note, we also have an unrelated liability that is owed to AXA associated with underwriting losses on a product sold by a distributor in our former lifestyle protection insurance business. As of March 31, 2021 and December 31, 2020, the balance of the liability is $21 million and $16 million, respectively, and is included as liabilities related to discontinued operations in our condensed consolidated balance sheets. The after-tax million was reflected as a loss from discontinued operations for the three months ended March 31, 2021. We have established our current best estimates for future claims that are still being processed under the settlement agreement, as well as for the unrelated liability related to underwriting losses and other expenses; however, there may be future adjustments to these estimates. If amounts are different from our estimates, it could result in an adjustment to our liabilities and an additional amount reflected in income (loss) from discontinued operations.

Disclosue of Accounting Changes [Abstract]
Accounting Pronouncements Recently Adopted	Accounting Pronouncements Recently Adopted On January 1, 2021, we adopted new accounting guidance related to simplifying the accounting for income taxes. The guidance eliminates certain exceptions related to the approach for intraperiod tax allocation, the methodology for calculating income taxes in an interim period and the recognition of deferred tax liabilities for outside basis differences. We adopted this new accounting guidance using the retrospective method or modified retrospective method for certain changes and prospective method for all other changes, which did not have a significant impact on our consolidated financial statements and disclosures.
Accounting Pronouncements Not Yet Adopted	Accounting Pronouncements Not Yet Adopted In August 2018, the Financial Accounting Standards Board (the “FASB”) issued new accounting guidance that significantly changes the recognition and measurement of long-duration insurance contracts and expands disclosure requirements, which impacts our life insurance deferred acquisition costs (“DAC”) and liabilities. In accordance with the guidance, the more significant changes include: • assumptions will no longer be locked-in at contract inception and all cash flow assumptions used to estimate the liability for future policy benefits (except the discount rate) will be reviewed at least annually in the same period each year or more frequently if actual experience indicates a change is required. Changes will be recorded in net income (loss) using a retrospective approach with a cumulative catch-up adjustment by recalculating the net premium ratio (which will be capped at 100%) using actual historical and updated future cash flow assumptions; • the discount rate used to determine the liability for future policy benefits will be a current upper-medium grade (low credit risk) fixed-income instrument yield, which is generally interpreted to mean a single-A rated bond rate for the same duration, and is required to be reviewed quarterly, with changes in the discount rate recorded in other comprehensive income (loss); • the provision for adverse deviation and the premium deficiency test will be eliminated; • market risk benefits associated with deposit-type contracts will be measured at fair value with changes related to instrument-specific credit risk recorded in other comprehensive income (loss) and remaining changes recorded in net income (loss); • the amortization method for DAC will generally be on a straight-line basis over the expected contract term; and • disclosures will be greatly expanded to include significant assumptions and product liability rollforwards. This guidance is effective for us on January 1, 2023 using the modified retrospective method for all topics except for market risk benefits, which is required to be applied using the retrospective method, with early adoption permitted, which we do not intend to elect. Given the nature and extent of the changes to our operations, this guidance is expected to have a significant impact on our consolidated financial statements.

Therefore, as a result of our loss from continuing operations available to Genworth Financial, Inc.’s common stockholders for the three months ended March 31, 2020, we were required to use basic weighted-average common shares outstanding as the inclusion of shares for stock options, restricted stock units and stock appreciation rights of 5.4 million 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 ended March 31, 2020, dilutive potential weighted-average common shares outstanding would have been 509.7 million.

[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 months ended March 31, 2020, we were required to use basic weighted-average common shares outstanding as the inclusion of shares for stock options, restricted stock units and stock appreciation rights of 5.4 million 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 ended March 31, 2020, dilutive potential weighted-average common shares outstanding would have been 509.7 million.
