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 of its 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 its affiliate companies in which it holds a majority voting interest or power to direct activities of certain variable interest entities (“VIEs”), which on a consolidated basis is referred to as “Genworth,” the “Company,” “we,” “us” or “our” unless the context otherwise requires. All intercompany accounts and transactions have been eliminated in consolidation. References to “Genworth Financial” refer solely to Genworth Financial, Inc., and not to any of its consolidated subsidiaries. Beginning in the first quarter of 2023, we changed our operating segments to better align with how we manage our business. The changes allow us to sharpen our focus on common aspects of products within each segment and enhance understanding of business performance. All prior period financial information has been re-presented • Enact. • Long-Term Care Insurance. • Life and Annuities. non-traditional In addition to our three operating segments, we also have Corporate and Other, which includes 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 reported outside of our operating segments, such as certain international businesses and discontinued operations. Corporate and Other also includes start-up fee-based 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 2022 Annual Report on Form 10-K. On May 2, 2022, Genworth Financial’s Board of Directors authorized a share repurchase program under which Genworth Financial may repurchase up to $350 million of its outstanding Class A common stock. On July 31, 2023, Genworth Financial’s Board of Directors authorized an additional $350 million of share repurchases under the existing share repurchase program. Pursuant to the program, during the nine months ended September 30, 2023, Genworth Financial repurchased 45,839,750 shares of its common stock at an average price of $5.68 per share for a total cost of $264 million, including excise taxes and other costs paid in connection with acquiring the shares. The repurchased shares were recorded at cost and presented as treasury stock in a separate caption in equity in our condensed consolidated balance sheets. Genworth Financial also authorized share repurchases through a Rule 10b5-1 10b5-1

Accounting Changes

Disclosue of Accounting Changes [Abstract]
Accounting Changes	(2) Accounting Changes Accounting Pronouncements Recently Adopted On January 1, 2023, we adopted new accounting guidance that significantly changed the recognition and measurement of long-duration insurance contracts, commonly known as long-duration targeted improvements (“LDTI”). This new accounting guidance directly impacted deferred acquisition costs (“DAC”), intangible assets and insurance assets and liabilities in our U.S. life insurance companies, and also significantly increased our disclosure requirements. While the new guidance has had a significant impact on existing U.S. GAAP financial statements and disclosures, it does not impact the cash flows or underlying economics of the business, business strategy, statutory net income (loss), risk-based capital of our U.S. life insurance companies, management of capital or our Enact segment and Corporate and Other. We adopted this new accounting guidance using the modified retrospective transition method for all topics except for market risk benefits (“MRBs”), which was required to be applied using the retrospective transition method. The modified retrospective transition method generally results in applying the guidance to contracts on the basis of existing carrying values as of January 1, 2021 (the “Transition Date”). The new accounting guidance, for all topics, was applied as of the Transition Date with an adjustment to beginning retained earnings and accumulated other comprehensive income (loss). In addition, prior period financial information has been re-presented with the new accounting standard. As of the Transition Date, we decreased total stockholders’ equity by $13.7 billion after-tax. single-A locked-in As a result of adopting this new accounting guidance, our insurance assets and liabilities have been sensitive to movements in interest rates, which will likely result in continued volatility to our stockholders’ equity. Refer to note 20 for additional detail related to the impact changes in interest rates have had on our accumulated other comprehensive income (loss) resulting from updating the discount rate used to measure the liability for future policy benefits and related reinsurance recoverables. The key areas of change introduced by the adoption of LDTI and the related effect to our accounting policies are summarized in the table below. Less significant accounting policy changes from adopting LDTI are not included in the below table. Key Area Impacted Change to Accounting Policy Policy Elections and Other Significant Matters DAC and balances amortized on a basis consistent with DAC, including intangible assets and cost of reinsurance DAC associated with long-duration insurance contracts is grouped into cohorts consistent with groupings used to estimate the related liability for future policy benefits and is amortized on a constant level basis over the expected contract term, which approximates straight-line. Assumptions used to amortize DAC are consistent with the assumptions used to estimate the liability for future policy benefits. Revised assumptions are recognized prospectively over the remaining term of the related contract. DAC and balances amortized on a basis consistent with DAC are no longer subject to impairment, shadow adjustments or recoverability testing; however, present value of future profits (“PVFP”) is still assessed for recoverability in connection with premium deficiency testing. The constant level basis we use to amortize DAC by product is as follows: •  long-term care insurance – total life count •  life insurance – face amount •  fixed and variable annuities – policy count We apply the amortization rate at the beginning of the current reporting period, which reflects assumption updates, if applicable, and actual experience through the end of the current reporting period. We have elected to amortize intangible assets associated with investment contracts, such as PVFP, in a manner consistent with DAC. Cost of reinsurance is deferred and amortized in a manner consistent with DAC over the terms of the related reinsurance treaties. Key Area Impacted Change to Accounting Policy Policy Elections and Other Significant Matters MRBs, which include contracts or contract features that protect the policyholder’s account balance and expose the insurer to other-than-nominal capital market risk, such as guaranteed minimum death benefits (“GMDBs”), guaranteed minimum withdrawal benefits (“GMWBs”) and guaranteed payout annuity floor benefits (“GPAFs”) MRBs are measured at fair value with changes related to instrument-specific credit risk recorded as a separate component in accumulated other comprehensive income (loss) and remaining changes recorded in net income (loss). For additional details, see notes 7 and 13. Liability for future policy benefits – level of aggregation For the purpose of calculating the net premium ratio used to measure the liability for future policy benefits, long-duration insurance contracts are grouped into annual cohorts on the basis of original contract issue date. For acquired contracts, the acquisition date is considered the original contract issue date. The net premium ratio for long-duration traditional and limited-payment contracts is the ratio of expected benefits less the existing carrying value of reserves to gross premiums. Traditional and limited-payment long-duration insurance contracts are generally grouped into annual calendar-year cohorts based on the contract issue date, product type and company. Limited-payment contracts are grouped into cohorts separately from other traditional products and riders are combined with the associated base policies. Certain products may also be grouped by acquisition date for acquired contracts and reinsurance treaty effective date for reinsurance recoverables. Key Area Impacted Change to Accounting Policy Policy Elections and Other Significant Matters Liability for future policy benefits – cash flow assumptions All cash flow assumptions used to estimate the liability for future policy benefits (including health care experience, policyholder persistency or lapses (i.e., the probability that a policy or contract will remain in-force in-force catch-up locked-in locked-in Cash flow assumptions no longer reflect a provision for adverse deviation, and the premium deficiency test and shadow adjustments are eliminated. We calculate a single liability for future policy benefits and therefore, all cash flows, including benefit payments (such as claims in course of settlement and incurred claims) are aggregated. As a result, our U.S. life insurance companies elected to combine their previously disclosed liability for policy and contract claims, excluding amounts related to certain life and annuity products not subject to the new accounting guidance, within the liability for future policy benefits and present the aggregate liability as one line item in our condensed consolidated balance sheets. Cash flow assumptions will be formally reviewed and updated as necessary based on experience studies in the fourth quarter each year. We elected to update the net premium ratio quarterly for actual versus expected experience; therefore, during interim reporting periods we will replace forecasted cash flow assumptions with actual cash flows with any difference recorded in net income (loss). We made an entity-wide election not to update our expense assumptions and therefore, these assumptions remain locked-in Key Area Impacted Change to Accounting Policy Policy Elections and Other Significant Matters Liability for future policy benefits – discount rate assumptions The liability for future policy benefits is measured using two different discount rates, a current discount rate and a locked-in The current discount rate is used to remeasure the liability for future policy benefits recorded in the condensed consolidated balance sheets and is a current upper-medium grade fixed-income instrument yield, commonly interpreted to be a single-A The locked-in locked-in For policies in-force locked-in locked-in single-A The methodology used to determine the current discount rate assumption maximizes the use of relevant observable inputs and minimizes the use of unobservable inputs. The current discount rate assumption is based on a single-A 10-K For contracts issued on or after the Transition Date, the locked-in single-A Key Area Impacted Change to Accounting Policy Policy Elections and Other Significant Matters Liability for future policy benefits – deferred profit liability A deferred profit liability is established for limited-payment products at the time of contract issuance for any amount of gross premiums received in excess of net premiums, which is amortized into net income (loss) in proportion to insurance in-force The deferred profit liability is recalculated using updated cash flow assumptions as of the beginning of the current reporting period and compared to the current carrying amount as of the beginning of the current reporting period, with any difference recorded in net income (loss). Policyholder account balances – additional insurance liabilities Additional insurance liabilities are established for guarantees or certain product features not classified as MRBs or embedded derivatives. The remeasurement of additional insurance liabilities based on a revised benefit ratio is recorded as liability remeasurement (gains) losses in current period net income (loss). The calculation of additional insurance liabilities also includes investment performance. Therefore, the impacts from net unrealized investment gains and losses on available for-sale available-for-sale Annual premium deficiency testing is still required to be performed for our universal and term universal life insurance products.

The guidance clarifies existing fair value guidance on measuring the fair value of an equity security subject to contractual sale restrictions and adds new disclosures related to these securities. This guidance is currently effective for us on January 1, 2024 using the prospective method, with early adoption permitted, which we do not intend to elect. We do not expect a significant impact from this guidance on our condensed consolidated financial statements and disclosures.

Long Term Duration Insurance Contracts [Abstract]
Long-Duration Insurance Contracts Targeted Improvements	(3) Long-Duration Insurance Contracts Targeted Improvements Transition Disclosures On January 1, 2023, we adopted LDTI using the modified retrospective method for all topics except for MRBs, which was adopted using the retrospective method, as of January 1, 2021 or the Transition Date. When applying the new accounting guidance for MRBs, hindsight was applied where necessary to determine actuarial assumptions for MRBs primarily associated with variable annuities for certain older blocks of business issued before 2003 and certain small runoff blocks of business as observable data was not available. The modified retrospective approach for DAC and balances amortized on a basis consistent with DAC was applied before MRBs were retrospectively measured and, as a result, the historical DAC balances were carried over as of the Transition Date. In the year of adoption only, we have included rollforwards of activity for the year ended December 31, 2021 for DAC, PVFP, the liability for future policy benefits, policyholder account balances, additional insurance liabilities, MRBs and separate account liabilities in notes 8, 9, 10, 11, 12, 13 and 14, respectively, to provide additional information related to comparative post-transition impacts. The following table presents the balances of and changes in the condensed consolidated balance sheet on January 1, 2021 from the adoption of LDTI: Balances as of Effect of adopting LDTI Balances as of (Amounts in millions) Eliminate Changes in Change in Recognize Assets Total investments $ 74,701 $ —  $ —  $ —  $ —  $ 74,701 Cash, cash equivalents and restricted cash 2,561 —  —  —  —  2,561 Accrued investment income 655 —  —  —  —  655 Deferred acquisition costs 1,487 1,322 —  —  —  2,809 Intangible assets 157 114 —  —  —  271 Reinsurance recoverable 16,864 —  1,214 10,149 (92 ) 28,135 Less: Allowance for credit losses (45 ) —  —  —  —  (45 ) Reinsurance recoverable, net 16,819 —  1,214 10,149 (92 ) 28,090 Other assets 404 —  (89 ) —  248 563 Deferred tax asset 65 (1,515 ) 497 4,624 105 3,776 Market risk benefit assets —  —  —  —  22 22 Separate account assets 6,081 —  —  —  —  6,081 Assets related to discontinued operations 2,817 —  —  —  —  2,817 Total assets $ 105,747 $ (79 ) $ 1,622 $ 14,773 $ 283 $ 122,346 Liabilities and equity Liabilities: Future policy benefits $ 42,695 $ (4,456 ) $ 14,654 $ 31,893 $ —  $ 84,786 Policyholder account balances 21,503 (1,229 ) —  —  (641 ) 19,633 Market risk benefit liabilities —  —  —  —  1,310 1,310 Liability for policy and contract claims 11,486 —  (10,725 ) —  —  761 Unearned premiums 775 —  (468 ) —  —  307 Other liabilities 1,614 —  —  —  4 1,618 Long-term borrowings 3,403 —  —  —  —  3,403 Separate account liabilities 6,081 —  —  —  —  6,081 Liabilities related to discontinued operations 2,370 —  —  —  —  2,370 Total liabilities 89,927 (5,685 ) 3,461 31,893 673 120,269 Commitments and contingencies Equity: Class A common stock 1 —  —  —  —  1 Additional paid-in 12,008 —  —  —  —  12,008 Accumulated other comprehensive income (loss) 4,425 5,606 —  (17,120 ) (19 ) (7,108 ) Retained earnings 1,584 —  (1,839 ) —  (371 ) (626 ) Treasury stock, at cost (2,700 ) —  —  —  —  (2,700 ) Total Genworth Financial, Inc.’s stockholders’ equity 15,318 5,606 (1,839 ) (17,120 ) (390 ) 1,575 Noncontrolling interests 502 —  —  —  —  502 Total equity 15,820 5,606 (1,839 ) (17,120 ) (390 ) 2,077 Total liabilities and equity $ 105,747 $ (79 ) $ 1,622 $ 14,773 $ 283 $ 122,346 The following table summarizes the components of the transition adjustments within stockholders’ equity as of January 1, 2021 from the adoption of LDTI: (Amounts in millions) Accumulated Retained Total Deferred acquisition costs $ 1,322 $ —  $ 1,322 Intangible assets 114 —  114 Reinsurance recoverable 10,149 1,201 11,350 Other assets —  156 156 Future policy benefits (27,437 ) (3,537 ) (30,974 ) Policyholder account balances 1,229 —  1,229 Market risk benefits, net (24 ) (623 ) (647 ) Other liabilities —  (4 ) (4 ) Deferred taxes 3,114 597 3,711 Total $ (11,533 ) $ (2,210 ) $ (13,743 ) The cumulative effect adjustment recorded to accumulated other comprehensive income (loss) for DAC, intangible assets and the liability for policyholder account balances represents the elimination of previously recorded shadow adjustments related to unrealized gains and losses. The cumulative effect adjustment recorded to accumulated other comprehensive income (loss) for the liability for future policy benefits and reinsurance recoverables relates to the higher discount rate in effect immediately prior to adoption compared to the lower single-A in-force in-force The cumulative effect adjustment recorded to accumulated other comprehensive income (loss) for our net MRB liability relates to the cumulative effect of changes in the instrument-specific credit risk between the contract issue date and January 1, 2021. The difference between the fair value and the carrying amount of MRBs as of January 1, 2021, excluding the amounts recorded in accumulated other comprehensive income (loss), was recorded as a cumulative effect adjustment to retained earnings. Transition adjustments related to the recognition of reinsured MRBs are reflected as other assets and other liabilities.

(2) For limited-payment contracts, if the remeasured liability for future policy benefits under LDTI is (less) greater than the carrying value immediately before the Transition Date, the deferred profit liability is increased (decreased) with a corresponding (decrease) increase to the liability for future policy benefits.

securities in an unrealized 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 was largely due to increased interest rates and widening credit spreads and was 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.

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 Fair value (Amounts in millions) September 30, December 31, September 30, December 31, Derivatives designated as hedges Cash flow hedges: Interest rate swaps Other invested assets $ 12 $ 24 Other liabilities $ 884 $ 522 Foreign currency swaps Other invested assets 15 20 Other liabilities 1 —  Forward bond purchase commitments Other invested assets —  —  Other liabilities 3 —  Total cash flow hedges 27 44 888 522 Total derivatives designated as hedges 27 44 888 522 Derivatives not designated as hedges Equity index options Other invested assets 11 6 Other liabilities —  —  Financial futures (1) Other invested assets —  —  Other liabilities —  —  Forward bond purchase commitments Other invested assets —  —  Other liabilities 25 —  Fixed indexed annuity embedded derivatives Other assets —  —  Policyholder account balances (2) 174 202 Indexed universal life embedded derivatives Reinsurance recoverable —  —  Policyholder account balances (3) 14 15 Total derivatives not designated as hedges 11 6 213 217 Total derivatives $ 38 $ 50 $ 1,101 $ 739 (1) The period end valuations of financial futures were zero as a result of settling the margins on these contracts on a daily basis.

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 fixed indexed annuity embedded derivatives and indexed universal life embedded derivatives, the change between periods is best illustrated by the number of policies.

Of this amount, $138 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.

Fair Value of Financial Instruments	(7) Fair Value of Financial Instruments Recurring Fair Value Measurements We have fixed maturity securities, equity securities, limited partnerships, derivatives, short-term investments, embedded derivatives, separate account assets, MRBs 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 securities, equity securities and short-term investments The fair value of fixed maturity securities, equity securities and short-term investments is 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. 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 placements 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 September 30, 2023. 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 financial instruments carried at fair value 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.

Net asset value Limited partnerships. Market risk benefits MRBs are contracts or contract features that provide protection to the contractholder from other-than-nominal capital market risk while exposing us to other-than-nominal capital market risk. MRBs include certain contract features on fixed and variable annuity products that provide minimum guarantees, in addition to the policyholder account balance, such as GMDBs, GMWBs and GPAFs. MRBs are measured at fair value using an income-based valuation model based on current net amounts at risk, market data, experience and other factors. See note 2 for a discussion of our policy for recording changes in fair value of MRBs. MRB assets and liabilities for minimum guarantees are valued and presented separately from the related separate account and policyholder account balances. Fixed indexed annuities The valuation of fixed indexed annuities MRBs, which includes GMWB features, is based on an income approach that incorporates inputs such as policyholder behavior (GMWB withdrawal utilization, lapses and mortality), equity index volatility, expected future interest credited, forward interest rates and an adjustment to the discount rate to incorporate non-performance non-performance non-performance non-performance Variable annuities The valuation of our variable annuities MRBs, which includes GMWB, GMDB and GPAF features, is based on an income approach that incorporates inputs such as policyholder behavior (GMWB withdrawal utilization, lapses and mortality), equity index volatility, interest rates, equity index and fund correlation and an adjustment to the discount rate to incorporate non-performance non-performance non-performance non-performance Derivatives We consider counterparty collateral arrangements and rights of set-off non-performance non-performance non-performance Interest rate swaps. Foreign currency swaps. Equity index options. Financial futures. Forward bond purchase commitments. Other foreign currency contracts. Fixed indexed annuity and indexed universal life embedded derivatives We have fixed indexed annuity and 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.

(3) Flooring adjustments are necessary when a cohort’s present value of future net premiums exceeds the present value of future benefits. The flooring adjustment ensures that the liability for future policy benefits for each cohort is not less than zero. This adjustment is most prevalent in our term life insurance products due to their product design of a level premium period followed by annual premium rate increases. We complete the required comprehensive annual review of our cash flow assumptions for the liability for future policy benefits in the fourth quarter each year. We have elected to update the net premium ratio quarterly for differences between actual and expected experience; therefore, during interim reporting periods, we replace forecasted cash flow assumptions with actual cash flows with any difference recorded in net income (loss). Cash flow assumptions are monitored quarterly and are updated if emerging experience indicates a change is necessary. As a result, we expect to update the cash flow assumptions related to the implementation timing and approval amounts of in-force Long-term care insurance For the nine months ended September 30, 2023, the impact of actual versus expected experience resulted in an increase of $164 million in the liability for future policy benefits largely as a result of timing impacts related to a in-force rate action plan. In the fourth quarter of 2022, we refined several assumptions, including reducing our lapse assumption in light of favorable experience from our long-term care insurance legal settlement elections and benefit reductions and updating our interest rate assumption to reflect the impact of the higher interest rate environment. The favorable impacts from both the effect of changes in cash flow assumptions and actual versus expected experience were mainly attributable to the inclusion of a second legal settlement. We also evaluated our assumptions regarding expectations of future premium rate increase approvals and benefit reductions and made no significant changes to our 2022 multi-year in-force In the fourth quarter of 2021, we reviewed our assumptions including expected claim incidence and terminations, expenses, interest rates, benefit utilization trend and in-force in-force Life insurance The impact of actual versus expected experience for the nine months ended September 30, 2023 resulted in an increase of $18 million in the liability for future policy benefits. The increase was primarily due to unfavorable mortality experience in certain level premium period term life insurance blocks. There were no cash flow assumption changes for our life insurance products in the fourth quarter of 2022. The effect of actual versus expected experience in 2022 resulted in an increase of $37 million in the liability for future policy benefits. The increase was primarily driven by unfavorable mortality from COVID-19 and elevated death claims in a single cohort in 2022. In the fourth quarter of 2021, we completed our annual review of cash flow assumptions and recorded an increase to our liability for future policy benefits of $ million principally due to unfavorable pre-COVID-19 mortality. The effect of actual versus expected experience in 2021 resulted in an increase of $ million to our liability for future policy benefits primarily from unfavorable mortality due to COVID-19. Fixed annuities The impact of actual versus expected experience for the nine months ended September 30, 2023 and the year ended December 31, 2022 resulted in a decrease of $ million and $ million in the liability for future policy benefits, respectively, due principally to favorable mortality. Due to emerging experience on our structured settlements, we revised the mortality assumption to reflect unfavorable mortality rates, resulting in an increase of $ million, partially offset by a favorable actual to expected experience adjustment of $ million in 2021.

(2) Amount represents additional liabilities related to death or other insurance benefits that are recorded within policyholder account balances and are considered long-duration insurance contracts. See note 12 for additional information. The contracts underlying the annuitization or other insurance benefits, such as GMWB and guaranteed annuitization benefits, are considered “in the money” if the present value of the contractholder’s benefits is greater than the account value, or commonly referred to as the net amount at risk. For GMWBs and guaranteed annuitization benefits, the only way the contractholder can monetize the excess of the benefits over the account value of the contract is through lifetime withdrawals or lifetime income payments after annuitization. For those guarantees of benefits that are payable in the event of death, the net amount at risk is generally defined as the current guaranteed minimum death benefit in excess of the current account balance at the balance sheet date.

The effect of updating the benefit ratio for actual versus expected experience for the nine months ended September 30, 2023 and the years ended December 31, 2022 and 2021 increased our additional insurance liabilities by $30 million, $33 million and $40 million, respectively. The increase for the nine months ended September 30, 2023 was principally due to unfavorable mortality experience and higher projected benefits as compared to prior expectations. The increase for the years ended December 31, 2022 and 2021 was primarily due to unfavorable mortality experience. In the fourth quarter of 2022, as part of our annual review of assumptions, we decreased our additional insurance liabilities by $37 million in our universal and term universal life insurance products primarily related to higher interest rates. In the fourth quarter of 2021, as part of our annual review of assumptions, we increased our additional insurance liabilities by $85 million in our term universal and universal life insurance products primarily driven by unfavorable pre-COVID-19 mortality. The following table provides the weighted-average interest rates for our additional insurance liabilities as of the dates indicated: September 30, December 31, December 31, Interest accretion rate (1) 3.3 % 3.3 % 3.2 % Projected crediting rate (2) 3.8 % 3.8 % 3.6 % (1) The interest accretion rate is determined by using the weighted-average policyholder crediting rates for the underlying policies over the period in-force, (2) The projected crediting rate is determined by using a future crediting rate curve that utilizes a portfolio approach reflecting anticipated reinvestment activity and runoff of existing assets over the projection period. The projected crediting rate is used to discount future assessments and excess benefits. The following table sets forth the amount of revenue and interest expense recognized in net income related to additional insurance liabilities for the periods indicated: Three months ended Nine months ended Years ended (Amounts in millions) 2023 2022 2023 2022 2022 2021 Gross assessments $ 134 $ 136 $ 406 $ 427 $ 559 $ 592 Interest expense (1) $ 22 $ 22 $ 66 $ 63 $ 85 $ 77 (1) Amounts for interest accretion, labeled “interest expense” in the table above, are included in benefits and other changes in policy reserves in the condensed consolidated statements of income.

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 Enact segment 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, as well as the timing and severity of those payments. Given the extended period of time that may exist between the reporting of a delinquency and the claim payment, and changes in economic conditions and the real estate market, significant uncertainty and variability exist on amounts actually paid. The favorable development related to insured events of prior years for the nine months ended September 30, 2023 was predominantly associated with $188 million of reserve releases in our Enact segment primarily related to favorable cure performance on delinquencies from 2022 and earlier, including those related to COVID-19.

Claims submitted for payment are generally due in less than one year. As of September 30, 2023, we had no reinsurance recoverables past due. As of December 31, 2022, we did not have any reinsurance recoverables past due, except for Scottish Re US Inc. (“Scottish Re”), a reinsurance company domiciled in Delaware. On March 6, 2019, Scottish Re was ordered into receivership for the purposes of rehabilitation by the Court of Chancery of the State of Delaware. The proposed Plan of Rehabilitation of Scottish Re was filed on June 30, 2020. On March 16, 2021, the Receiver filed a draft Amended Plan of Rehabilitation and filed an outline of changes to the amended plan on July 27, 2021. In May 2023, the Receiver concluded that Scottish Re should be liquidated based upon adverse changes in its financial condition subsequent to the filing of the Amended Plan of Rehabilitation. In July 2023, Scottish Re’s board of directors consented to the liquidation order, which was made final by the Court shortly thereafter. In addition, the Court’s liquidation order mandated all reinsurance agreements in-force We previously established an allowance for credit losses of $36 million related to the reinsurance recoverable due from Scottish Re. In the third quarter of 2023, we determined that the reinsurance recoverable was uncollectible. As a result, we recorded an additional credit loss of $33 million and wrote off the entire reinsurance recoverable of $69 million against the allowance for credit losses. As of September 30, 2023, we recaptured all of our life insurance policies from Scottish Re, which did not have a significant impact on our current period earnings, as the credit loss recognized in the third quarter of 2023 was offset by the derecognition of ceded premiums of approximately $33 million where we have the right of offset for the amounts owed to us by Scottish Re.

However, in certain circumstances it is appropriate to record the actual effective tax rate for the period if a reliable full year estimate cannot be made. For the three and nine months ended September 30, 2023, we utilized the actual effective tax rate for the interim periods to record the provision for income taxes for our Long-Term Care Insurance and Life and Annuities segments and the annualized projected effective tax rate for our Enact segment and Corporate and Other. For the three and nine months ended September 30, 2022, we utilized the effective tax rate for the year ended December 31, 2022 in determining the re-presented Our ability to realize our deferred tax assets is largely dependent upon generating sufficient taxable income and capital gains in future years. As of September 30, 2023 and December 31, 2022, our tax valuation allowance was $748 million and $583 million, respectively, of which $350 million and $200 million, respectively, were related to capital deferred tax assets. Given the increase in unrealized losses on our fixed maturity securities and forward starting swaps in the current year due to rising interest rates and the corresponding reduction in the amount of unrealized capital gains expected to be available in the future to offset our capital loss carryforwards and other capital deferred tax assets, we recorded an additional valuation allowance of $150 million in the third quarter of 2023 through accumulated other comprehensive income (loss) related to deferred tax assets that would produce capital losses. The remainder of the total valuation allowance relates to foreign and state net operating loss carryforwards.

The products in the Life and Annuities segment include traditional and non-traditional (term, universal and term universal life insurance as well as corporate-owned life insurance and funding agreements), fixed annuities and variable annuities (which include variable life insurance), none of which are actively marketed or sold. In addition to our three operating segments, we also have Corporate and Other, which includes 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 reported outside of our operating segments, such as certain international businesses and discontinued operations. Corporate and Other also includes start-up fee-based 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. 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. U.S. GAAP generally requires an annualized effective tax rate to be used for interim reporting periods, utilizing projections of full year results. However, in certain circumstances it is appropriate to record the actual effective tax rate for the period if a reliable full year estimate cannot be made. See note 17 for a discussion of the effective tax rates used for our segments and Corporate and Other for the three and nine months ended September 30, 2023 and 2022. We use the same accounting policies and procedures to measure segment income (loss) and assets as our consolidated net income and assets. Our President and Chief Executive Officer (Principal Executive Officer), who serves as 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-operating While some of these items may be significant components of net income (loss) available to Genworth Financial, Inc.’s common stockholders in accordance with U.S. GAAP, we believe that adjusted operating income (loss) available to Genworth Financial, Inc.’s common stockholders, and measures that are derived from or incorporate adjusted operating income (loss) available to Genworth Financial, Inc.’s common stockholders, are appropriate measures that are useful to investors because they identify the income (loss) attributable to the ongoing operations of the business. Management also uses adjusted operating income (loss) available to Genworth Financial, Inc.’s common stockholders as a basis for determining awards and compensation for senior management and to evaluate performance on a basis comparable to that used by analysts. However, the items excluded from adjusted operating income (loss) available to Genworth Financial, Inc.’s common stockholders have occurred in the past and could, and in some cases will, recur in the future. Adjusted operating income (loss) available to Genworth Financial, Inc.’s common stockholders is not a substitute for net income (loss) available to Genworth Financial, Inc.’s common stockholders determined in accordance with U.S. GAAP. In addition, our definition of adjusted operating income (loss) available to Genworth Financial, Inc.’s common stockholders may differ from the definitions used by other companies. Adjustments to reconcile net income (loss) available to Genworth Financial, Inc.’s common stockholders to adjusted operating income (loss) assume a 21% tax rate and are net of the portion attributable to noncontrolling interests. Changes in fair value of market risk benefits and associated hedges are adjusted to exclude changes in reserves, attributed fees and benefit payments.

Commitments and Contingencies	(19) 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 mortgage insurance subsidiaries, such as captive reinsurance arrangements with lenders and contract underwriting services, violations of the Real Estate Settlement and Procedures Act of 1974 or related state anti-inducement laws, and mortgage insurance policy rescissions and curtailments, and breaching fiduciary or other duties to customers, including but not limited to breach of customer information. Plaintiffs in class action and other lawsuits against us may seek very large or indeterminate amounts which may remain unknown for substantial periods of time. In our investment-related operations, we are subject to litigation involving commercial disputes with counterparties. We are also subject to litigation arising out of our general business activities such as our contractual and employment relationships, including claims under the Employee Retirement Income Security Act of 1974, 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 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 renewed our motion for leave to file a counterclaim. The briefing on both motions concluded in October 2021. On March 24, 2022, the Court denied our motions. On April 11, 2022, we filed an appeal of the Court’s denial to the United States Court of Appeals for the Eleventh Circuit. On June 22, 2022, we filed our opening brief in support of the appeal. Plaintiff filed its respondent’s brief on September 20, 2022, and we filed our reply brief on November 10, 2022. The appeal was orally argued on August 17, 2023, and we are awaiting a decision from the Eleventh Circuit. We intend to continue to vigorously defend this action. 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 pay-off In January 2021, GLAIC 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 injunctive relief, and sought damages in excess of $5 million. On February 10, 2023, the parties reached an agreement in principle to settle the action for an immaterial amount. On April 14, 2023, the action was dismissed on stipulation. On August 11, 2021, GLIC and Genworth Life Insurance Company of New York received a request for pre-suit pre-suit Fred Haney, Marsha Merrill, Sylvia Swanson, and Alan Wooten, individually, and on behalf of all others similarly situated v. Genworth Life Insurance Company and Genworth Life Insurance Company of New York On August 1, 2022, a putative class action was filed in the United States District Court for the Eastern District of Virginia by two former Genworth employees against Genworth Financial, its Board of Directors and the Fiduciary and Investments Committee of Genworth Financial’s Retirement and Savings Plan (“Savings Plan”). Plaintiffs purport to act on behalf of the Savings Plan and all similarly simulated participants and beneficiaries of the Savings Plan. The complaint asserts that the defendants breached their fiduciary duties under the Employee Retirement Income Security Act of 1974 by imprudently offering and inadequately monitoring a suite of BlackRock Target Date Funds as a retirement investment option for Genworth employees. Plaintiffs seek declaratory and injunctive relief, monetary damages, and attorney’s fees. By stipulation entered September 6, 2022, the complaint was dismissed, without prejudice, against the Board of Directors and the Fiduciary and Investments Committee of Genworth Financial’s Savings Plan. On October 17, 2022, we moved to dismiss the complaint against the sole remaining defendant, Genworth Financial. Plaintiffs filed opposition papers on November 10, 2022, and we filed our reply papers on November 16, 2022. By order dated January 20, 2023, the Court granted plaintiffs’ motion to serve an amended complaint, rendering our initial motion to dismiss moot. On January 20, 2023, plaintiffs filed an amended complaint, and on February 2, 2023, we filed a motion to dismiss the amended complaint. On March 16, 2023, the Court directed plaintiffs to file a second amended complaint and denied as moot our motion to dismiss the amended complaint. Plaintiffs filed the second amended complaint on April 17, 2023. On May 15, 2023, we answered and moved to dismiss the second amended complaint. On September 13, 2023, the Court granted in part and denied in part our motion to dismiss the second amended complaint. Discovery is now ongoing, and trial is scheduled for May 20, 2024. We intend to continue to vigorously defend this action. On December 16, 2022, Blue Cross Blue Shield of Nebraska (“BCBSNE”) served an arbitration demand on GLIC in relation to BCBSNE’s stated intent to recapture a block of long-term care insurance policies for which the risk was partly ceded to GLIC. In its arbitration demand, BCBSNE alleges that GLIC breached the governing reinsurance agreement by refusing to agree to transfer assets equal to the fair value of the liabilities being recaptured. BCBSNE asserts it has satisfied all of its obligations under the reinsurance agreement and is seeking to recapture the ceded block of reinsurance. BCBSNE seeks damages equal to the fair value of the recaptured liabilities, plus interest and other damages, including attorneys’ fees and costs. The arbitration panel has been appointed and an organizational meeting was held on August 30, 2023. The trial is scheduled for September and October of 2024. We intend to vigorously defend this arbitration proceeding. Starting in June 2023, various Genworth entities (including Genworth Financial, GLIC and GLAIC) have been named as defendants in certain of ten putative class action lawsuits in the United States District Courts for the Eastern District of Virginia and the District of Massachusetts. These cases are captioned as follows: King v. Genworth Financial, Inc Anastasio v. Genworth Financial, Inc. et al Hauser v. Genworth Life Insurance Company Smith v. Genworth Financial, Inc. Behrens v. Genworth Life Insurance Company Hale et al v. Genworth Financial, Inc. Burkett, Jr. v. Genworth Life and Annuity Insurance Company Manar v. Genworth Financial, Inc. Kennedy v. Genworth Financial, Inc. Bailey v. Genworth Financial, Inc On October 20, 2023, GLIC was named as the defendant in a putative class action lawsuit in the United States District Court for the Eastern District of Virginia captioned Martin Silverstein, on behalf of himself and all others similarly situated v. Genworth Life Insurance Company At this time, we cannot determine or predict the ultimate outcome of any of the pending legal and regulatory matters specifically identified above or the likelihood of potential future legal and regulatory matters against us. In addition, 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 September 30, 2023, we were committed to fund $1,408 million in limited partnership investments, $136 million of bank loan investments, $12 million in private placement investments and $9 million of commercial mortgage loan investments.

Disclosue of Accounting Changes [Abstract]
Accounting Pronouncements Recently Adopted	Accounting Pronouncements Recently Adopted On January 1, 2023, we adopted new accounting guidance that significantly changed the recognition and measurement of long-duration insurance contracts, commonly known as long-duration targeted improvements (“LDTI”). This new accounting guidance directly impacted deferred acquisition costs (“DAC”), intangible assets and insurance assets and liabilities in our U.S. life insurance companies, and also significantly increased our disclosure requirements. While the new guidance has had a significant impact on existing U.S. GAAP financial statements and disclosures, it does not impact the cash flows or underlying economics of the business, business strategy, statutory net income (loss), risk-based capital of our U.S. life insurance companies, management of capital or our Enact segment and Corporate and Other. We adopted this new accounting guidance using the modified retrospective transition method for all topics except for market risk benefits (“MRBs”), which was required to be applied using the retrospective transition method. The modified retrospective transition method generally results in applying the guidance to contracts on the basis of existing carrying values as of January 1, 2021 (the “Transition Date”). The new accounting guidance, for all topics, was applied as of the Transition Date with an adjustment to beginning retained earnings and accumulated other comprehensive income (loss). In addition, prior period financial information has been re-presented with the new accounting standard. As of the Transition Date, we decreased total stockholders’ equity by $13.7 billion after-tax. single-A locked-in As a result of adopting this new accounting guidance, our insurance assets and liabilities have been sensitive to movements in interest rates, which will likely result in continued volatility to our stockholders’ equity. Refer to note 20 for additional detail related to the impact changes in interest rates have had on our accumulated other comprehensive income (loss) resulting from updating the discount rate used to measure the liability for future policy benefits and related reinsurance recoverables. The key areas of change introduced by the adoption of LDTI and the related effect to our accounting policies are summarized in the table below. Less significant accounting policy changes from adopting LDTI are not included in the below table. Key Area Impacted Change to Accounting Policy Policy Elections and Other Significant Matters DAC and balances amortized on a basis consistent with DAC, including intangible assets and cost of reinsurance DAC associated with long-duration insurance contracts is grouped into cohorts consistent with groupings used to estimate the related liability for future policy benefits and is amortized on a constant level basis over the expected contract term, which approximates straight-line. Assumptions used to amortize DAC are consistent with the assumptions used to estimate the liability for future policy benefits. Revised assumptions are recognized prospectively over the remaining term of the related contract. DAC and balances amortized on a basis consistent with DAC are no longer subject to impairment, shadow adjustments or recoverability testing; however, present value of future profits (“PVFP”) is still assessed for recoverability in connection with premium deficiency testing. The constant level basis we use to amortize DAC by product is as follows: •  long-term care insurance – total life count •  life insurance – face amount •  fixed and variable annuities – policy count We apply the amortization rate at the beginning of the current reporting period, which reflects assumption updates, if applicable, and actual experience through the end of the current reporting period. We have elected to amortize intangible assets associated with investment contracts, such as PVFP, in a manner consistent with DAC. Cost of reinsurance is deferred and amortized in a manner consistent with DAC over the terms of the related reinsurance treaties. Key Area Impacted Change to Accounting Policy Policy Elections and Other Significant Matters MRBs, which include contracts or contract features that protect the policyholder’s account balance and expose the insurer to other-than-nominal capital market risk, such as guaranteed minimum death benefits (“GMDBs”), guaranteed minimum withdrawal benefits (“GMWBs”) and guaranteed payout annuity floor benefits (“GPAFs”) MRBs are measured at fair value with changes related to instrument-specific credit risk recorded as a separate component in accumulated other comprehensive income (loss) and remaining changes recorded in net income (loss). For additional details, see notes 7 and 13. Liability for future policy benefits – level of aggregation For the purpose of calculating the net premium ratio used to measure the liability for future policy benefits, long-duration insurance contracts are grouped into annual cohorts on the basis of original contract issue date. For acquired contracts, the acquisition date is considered the original contract issue date. The net premium ratio for long-duration traditional and limited-payment contracts is the ratio of expected benefits less the existing carrying value of reserves to gross premiums. Traditional and limited-payment long-duration insurance contracts are generally grouped into annual calendar-year cohorts based on the contract issue date, product type and company. Limited-payment contracts are grouped into cohorts separately from other traditional products and riders are combined with the associated base policies. Certain products may also be grouped by acquisition date for acquired contracts and reinsurance treaty effective date for reinsurance recoverables. Key Area Impacted Change to Accounting Policy Policy Elections and Other Significant Matters Liability for future policy benefits – cash flow assumptions All cash flow assumptions used to estimate the liability for future policy benefits (including health care experience, policyholder persistency or lapses (i.e., the probability that a policy or contract will remain in-force in-force catch-up locked-in locked-in Cash flow assumptions no longer reflect a provision for adverse deviation, and the premium deficiency test and shadow adjustments are eliminated. We calculate a single liability for future policy benefits and therefore, all cash flows, including benefit payments (such as claims in course of settlement and incurred claims) are aggregated. As a result, our U.S. life insurance companies elected to combine their previously disclosed liability for policy and contract claims, excluding amounts related to certain life and annuity products not subject to the new accounting guidance, within the liability for future policy benefits and present the aggregate liability as one line item in our condensed consolidated balance sheets. Cash flow assumptions will be formally reviewed and updated as necessary based on experience studies in the fourth quarter each year. We elected to update the net premium ratio quarterly for actual versus expected experience; therefore, during interim reporting periods we will replace forecasted cash flow assumptions with actual cash flows with any difference recorded in net income (loss). We made an entity-wide election not to update our expense assumptions and therefore, these assumptions remain locked-in Key Area Impacted Change to Accounting Policy Policy Elections and Other Significant Matters Liability for future policy benefits – discount rate assumptions The liability for future policy benefits is measured using two different discount rates, a current discount rate and a locked-in The current discount rate is used to remeasure the liability for future policy benefits recorded in the condensed consolidated balance sheets and is a current upper-medium grade fixed-income instrument yield, commonly interpreted to be a single-A The locked-in locked-in For policies in-force locked-in locked-in single-A The methodology used to determine the current discount rate assumption maximizes the use of relevant observable inputs and minimizes the use of unobservable inputs. The current discount rate assumption is based on a single-A 10-K For contracts issued on or after the Transition Date, the locked-in single-A Key Area Impacted Change to Accounting Policy Policy Elections and Other Significant Matters Liability for future policy benefits – deferred profit liability A deferred profit liability is established for limited-payment products at the time of contract issuance for any amount of gross premiums received in excess of net premiums, which is amortized into net income (loss) in proportion to insurance in-force The deferred profit liability is recalculated using updated cash flow assumptions as of the beginning of the current reporting period and compared to the current carrying amount as of the beginning of the current reporting period, with any difference recorded in net income (loss). Policyholder account balances – additional insurance liabilities Additional insurance liabilities are established for guarantees or certain product features not classified as MRBs or embedded derivatives. The remeasurement of additional insurance liabilities based on a revised benefit ratio is recorded as liability remeasurement (gains) losses in current period net income (loss).

Accounting Pronouncements Not Yet Adopted	Accounting Pronouncements Not Yet Adopted In June 2022, the FASB issued new accounting guidance related to the fair value measurement of equity securities subject to contractual sale restrictions. The guidance clarifies existing fair value guidance on measuring the fair value of an equity security subject to contractual sale restrictions and adds new disclosures related to these securities. This guidance is currently effective for us on January 1, 2024 using the prospective method, with early adoption permitted, which we do not intend to elect. We do not expect a significant impact from this guidance on our condensed consolidated financial statements and disclosures.

[1]Net premiums collected represents the portion of gross premiums collected from policyholders that is used to fund expected benefit payments.[2]Related to a third-party recapture of certain single premium immediate annuity contracts in 2022.[3]Flooring adjustments are necessary when a cohort’s present value of future net premiums exceeds the present value of future benefits. The flooring adjustment ensures that the liability for future policy benefits for each cohort is not less than zero. This adjustment is most prevalent in our term life insurance products due to their product design of a level premium period followed by annual premium rate increases.[4]The components of the life insurance rollforward exclude flooring.
