Organization, Consolidation and Presentation of Financial Statements [Abstract]
Nature of business, organization structure and basis of presentation	Nature of business, organization structure and basis of presentation The accompanying unaudited condensed consolidated financial statements include, on a consolidated basis, the accounts of Enact Holdings, Inc. (“EHI,” together with its subsidiaries, the “Company,” “we,” “us” or “our”) (formerly known as Genworth Mortgage Holdings, Inc.). EHI is a subsidiary of Genworth Financial, Inc. (“Genworth” or “Parent”) and has been since EHI’s incorporation in Delaware in 2012. In September 2021, we completed a minority initial public offering (“IPO”) of 18.4% of EHI’s common stock. We are engaged in the business of writing and assuming residential mortgage guaranty insurance. The insurance protects lenders and investors against certain losses resulting from nonpayment of loans secured by mortgages, deeds of trust, or other instruments constituting a lien on residential real estate. We offer private mortgage insurance products predominantly insuring prime-based, individually underwritten residential mortgage loans (“primary mortgage insurance”). Our primary mortgage insurance enables borrowers to buy homes with a down payment of less than 20% of the home’s value. Primary mortgage insurance also facilitates the sale of these low down payment mortgage loans in the secondary mortgage market, most of which are sold to government sponsored enterprises. We also selectively enter into insurance transactions with lenders and investors, under which we insure a portfolio of loans at or after origination. We also perform fee-based contract underwriting services for mortgage lenders. The provision of underwriting services by mortgage insurers eliminates the duplicative lender and mortgage insurer underwriting activities and expedites the approval process. We operate our business through our primary insurance subsidiary, Enact Mortgage Insurance Corporation, (“EMICO”), formerly known as Genworth Mortgage Insurance Corporation, with operations in all 50 states and the District of Columbia. We completed name changes to some of our subsidiary legal entities during the first quarter of 2022. EMICO is an approved insurer by the Federal National Mortgage Association (“Fannie Mae”) and the Federal Home Loan Mortgage Corporation (“Freddie Mac”). Fannie Mae and Freddie Mac are government-sponsored enterprises and we refer to them collectively as the “GSEs.” We also offer mortgage-related insurance and reinsurance through our wholly owned Bermuda-based subsidiary, Enact Re Ltd. ("Enact Re"). We contributed $250 million into Enact Re during the second quarter of 2023. As of June 30, 2023, Enact Re provided reinsurance relating to GSE risk share and reinsures EMICO’s new and existing insurance in-force under quota share reinsurance agreements. We operate our business in a single segment, which is how our chief operating decision maker (who is our Chief Executive Officer) reviews our financial performance and allocates resources. Our segment includes a run-off insurance block with reference properties in Mexico (“run-off business”), which is immaterial to our condensed consolidated financial statements. The accompanying condensed consolidated financial statements are unaudited and have been prepared in accordance with U.S. generally accepted accounting principles (“U.S. GAAP”). 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.

Based on a qualitative and quantitative review of the issuers of the securities, we believe the unrealized losses are largely due to changes in interest rates and recent market volatility, and are 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. The following table presents the gross unrealized losses and fair values of our fixed maturity securities, aggregated by investment type and length of time that individual fixed maturity securities have been in a continuous unrealized loss position, as of December 31, 2022: Less than 12 months 12 months or more Total (Amounts in thousands) Fair value Gross unrealized losses Number of securities Fair value Gross unrealized losses Number of securities Fair value Gross unrealized losses Number of securities Fixed maturity securities: U.S. government, agencies and GSEs $ 43,873 $ (1,600) 18 $ 96 $ (9) 1 $ 43,969 $ (1,609) 19 State and political subdivisions 203,752 (40,988) 43 196,235 (56,906) 46 399,987 (97,894) 89 Non-U.S. government — — — 9,349 (1,258) 1 9,349 (1,258) 1 U.S. corporate 2,033,713 (131,150) 468 568,171 (109,611) 92 2,601,884 (240,761) 560 Non-U.S. corporate 486,117 (35,515) 125 155,345 (28,132) 27 641,462 (63,647) 152 Residential mortgage-backed 11,043 (119) 6 — — — 11,043 (119) 6 Other asset-backed 655,525 (31,684) 217 375,810 (53,790) 71 1,031,335 (85,474) 288 Total for fixed maturity securities in an unrealized loss position $ 3,434,023 $ (241,056) 877 $ 1,305,006 $ (249,706) 238 $ 4,739,029 $ (490,762) 1,115 Contractual Maturities of Fixed Maturity Securities Available-For-Sale The scheduled maturity distribution of fixed maturity securities as of June 30, 2023, is set forth below.

Fair Value Disclosures [Abstract]
Fair value	Fair value Recurring fair value measurements We hold fixed maturity securities and short-term investments, which are carried at fair value. The fair value of fixed maturity securities and short-term investments 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 asset-backed securities), an income or combination 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 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 June 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 fixed maturity securities and short-term investments 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 There were no fixed maturity securities classified as Level 1 as of June 30, 2023, and December 31, 2022. Level 2 measurements Fixed maturity securities: Third-party pricing services In estimating the fair value of fixed maturity securities, approximately 89% of our portfolio was priced using third-party pricing services as of June 30, 2023. These pricing services utilize industry-standard valuation techniques that include market-based approaches, income-based approaches, a combination of market-based and income-based approaches or other proprietary, internally generated models as part of the valuation processes. These third-party pricing vendors maximize the use of publicly available data inputs to generate valuations for each asset class. Priority and type of inputs used may change frequently as certain inputs may be more direct drivers of valuation at the time of pricing. Examples of significant inputs incorporated by pricing services may include sector and issuer spreads, seasoning, capital structure, security optionality, collateral data, prepayment assumptions, default assumptions, delinquencies, debt covenants, benchmark yields, trade data, dealer quotes, credit ratings, maturity and weighted-average life. We conduct regular meetings with our pricing services for the purpose of understanding the methodologies, techniques and inputs used by the third-party pricing providers. 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 June 30, 2023: (Amounts in thousands) Fair value Primary methodologies Significant inputs U.S. government, agencies and GSEs $ 110,538 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 $ 426,528 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 $ 11,206 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 $ 2,105,532 Multi-dimensional attribute-based modeling systems, broker quotes, price quotes from market makers, internal models, OAS-based models Bid side prices to Treasury Curve, Issuer Curve, which includes sector, quality, duration, OAS percentage and change for spread matrix, trade prices, comparative transactions, Trade Reporting and Compliance Engine (“TRACE”) reports Non-U.S. corporate $ 495,138 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 $ 9,474 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 Other asset-backed $ 1,196,812 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 A portion of our Level 2 U.S. corporate and non-U.S. corporate securities are valued using internal models. The fair value of these fixed maturity securities was $181.6 million and $72.2 million, respectively, as of June 30, 2023. Internally modeled securities are primarily private fixed maturity securities where we use market observable inputs such as an interest rate yield curve, published credit spreads for similar securities based on the external ratings of the instrument and related industry sector of the issuer. Additionally, we may apply certain price caps and liquidity premiums in the valuation of private fixed maturity securities. Price caps and liquidity premiums are established using inputs from market participants. 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 Broker quotes A portion of our U.S. corporate and other asset-backed securities are valued using broker quotes. Broker quotes are obtained from third-party providers that have current market knowledge to provide a reasonable price for securities not routinely priced by pricing services. Brokers utilized for valuation of assets are reviewed annually. The fair value of our Level 3 fixed maturity securities priced by broker quotes was $23.3 million as of June 30, 2023. Internal models A portion of our U.S. corporate and non-U.S. corporate securities are valued using internal models. The primary inputs to the valuation of the bond population include quoted prices for identical assets, or similar assets in markets that are not active, contractual cash flows, duration, call provisions, issuer rating, benchmark yields and credit spreads. Certain private fixed maturity securities are valued using an internal model using market observable inputs such as the interest rate yield curve, as well as published credit spreads for similar securities, which includes significant unobservable inputs. Additionally, we may apply certain price caps and liquidity premiums in the valuation of private fixed maturity securities. Price caps are established using inputs from market participants. For structured securities, the primary inputs to the valuation include quoted prices for identical assets, or similar assets in markets that are not active, contractual cash flows, weighted-average coupon, weighted-average maturity, issuer rating, structure of the security, expected prepayment speeds and volumes, collateral type, current and forecasted loss severity, average delinquency rates, vintage of the loans, geographic region, debt service coverage ratios, payment priority with the tranche, benchmark yields and credit spreads. The fair value of our Level 3 fixed maturity securities priced using internal models was $282.7 million as of June 30, 2023.

Loss reserves

Loss reserves	6 Months Ended

Insurance [Abstract]
Loss reserves	Loss reserves Activity for the liability for loss reserves for the six months ended June 30, is summarized as follows: (Amounts in thousands) 2023 2022 Loss reserves, beginning balance $ 519,008 $ 641,325 Reinsurance recoverable, beginning balance — — Run-off reserves (678) (681) Net loss reserves, beginning balance 518,330 640,644 Losses and LAE incurred related to current accident year 120,175 75,562 Losses and LAE incurred related to prior accident years (135,366) (147,558) Total incurred (1) (15,191) (71,996) Losses and LAE paid related to current accident year (359) (461) Losses and LAE paid related to prior accident years (13,689) (9,966) Total paid (1) (14,048) (10,427) Net loss reserves, ending balance 489,091 558,221 Reinsurance recoverable, ending balance 213 — Run-off reserves 899 673 Loss reserves, ending balance $ 490,203 $ 558,894 ______________ (1) Losses and loss adjustment expenses (“LAE”) incurred and paid exclude losses related to our run-off business. The liability for loss reserves represents our current best estimate; however, there may be future adjustments to this estimate and related assumptions. Such adjustments, reflecting any variety of new and adverse trends, could possibly be significant, and result in future increases to reserves by amounts that could be material to our results of operations, financial condition and liquidity. Losses incurred related to insured events of the current accident year relate to defaults that occurred in that year and represent the estimated ultimate amount of losses to be paid on such defaults. Losses incurred related to insured events of prior accident years represent the (favorable) or unfavorable development of reserves as a result of the actual rates at which delinquencies go to claim (“claim rates”) and claim amounts being different than those we estimated when originally establishing the reserves. Such estimates are based on our historical experience, which we believe is representative of expected future losses at the time of estimation. As a result of the extended period of time that may exist between the reporting of a delinquency and the claim payment, as well as changes in economic conditions and the real estate market, significant uncertainty and variability exist on amounts ultimately paid. A portion of delinquencies in the periods presented were from borrowers participating in deferred or reduced payments (“forbearance”) as a result of COVID-19. When establishing loss reserves for borrowers in forbearance from 2020 to 2022, we assumed a lower rate of delinquencies becoming active claims, which had the effect of producing a lower reserve compared to delinquencies that were not in forbearance. Historical experience with localized natural disasters, such as hurricanes, indicates a higher cure rate for borrowers in forbearance. Loss reserves recorded on these new delinquencies have a high degree of estimation due to the level of uncertainty regarding whether delinquencies in forbearance will ultimately cure or result in claim payments as well as the timing and severity of those payments. For the six months ended June 30, 2023, losses and LAE incurred of $120 million related to insured events of the current accident year was primarily attributable to new delinquencies compared to $76 million for the six months ended June 30, 2022. We also recorded favorable adjustments on prior accident year reserves of $133 million, which were driven primarily by cure performance of delinquencies from 2021 and earlier, including those related to COVID-19 as well as delinquencies from early 2022. During the peak of COVID-19, we experienced elevated new delinquencies subject to forbearance plans. Those delinquencies have continued to perform at levels above our reserve expectations. A portion of the reserve release also related to delinquencies from the first half of 2022, as uncertainty in the economic environment has not negatively impacted cure performance as expected. During the first six months of 2022, we released $146 million of reserves primarily related to COVID-19 delinquencies from 2020.

Reinsurance

Reinsurance	6 Months Ended

SEC Schedule, 12-17, Insurance Companies, Reinsurance [Abstract]
Reinsurance	Reinsurance We reinsure a portion of our policy risks in order to reduce our ultimate losses, diversify our exposures and comply with regulatory requirements. We also assume certain policy risks written by other companies. Reinsurance does not relieve us from our obligations to policyholders. In the event that the reinsurers are unable to meet their obligations, we remain liable for the reinsured claims. We monitor both the financial condition of individual reinsurers and risk concentrations arising from similar geographic regions, activities and economic characteristics of reinsurers to lessen the risk of default by such reinsurers. The following table sets forth the effects of reinsurance on premiums written and earned for the periods indicated: Three months ended Six months ended (Amounts in thousands) 2023 2022 2023 2022 Net premiums written: Direct $ 245,160 $ 245,819 $ 486,099 $ 488,424 Assumed 256 66 315 134 Ceded (21,015) (20,129) (40,942) (38,431) Net premiums written $ 224,401 $ 225,756 $ 445,472 $ 450,127 Net premiums earned: Direct $ 259,279 $ 257,449 $ 514,255 $ 509,962 Assumed 256 66 315 134 Ceded (21,015) (20,129) (40,942) (38,431) Net premiums earned $ 238,520 $ 237,386 $ 473,628 $ 471,665 The difference between written premiums of $224.4 million and earned premiums of $238.5 million represents the decrease in unearned premiums for the three months ended June 30, 2023. The difference between written premiums of $445.5 million and earned premiums of $473.6 million represents the decrease in unearned premiums for the six months ended June 30, 2023. The decrease in unearned premiums was primarily the result of policy cancellations in our single premium mortgage insurance product. Excess-of-loss reinsurance We engage in excess-of-loss (“XOL”) insurance transactions either through a panel of traditional reinsurance providers or through collateralized reinsurance with unaffiliated special purpose insurers (“Triangle Re Entities”). During the respective coverage periods of these agreements, EMICO retains the first layer of aggregate loss exposure on covered policies while the reinsurer provides the second layer of coverage, up to the defined reinsurance coverage amount. EMICO retains losses in excess of the respective reinsurance coverage amount. The Triangle Re Entities fully collateralize their coverage by issuing insurance-linked notes (“ILNs”) to eligible capital market investors in unregistered private offerings. Traditional reinsurance providers collateralize a portion of their coverage by holding funds in trust. We believe that the risk transfer requirements for reinsurance accounting were met as these excess of loss insurance transactions assume significant insurance risk and a reasonable possibility of significant loss.

Accounting Policies [Abstract]
Accounting Pronouncements Recently Adopted and Accounting Pronouncements Not Yet Adopted	Accounting Pronouncements Recently Adopted We have not adopted new accounting pronouncements in 2023. Accounting Pronouncements Not Yet Adopted There are no significant new accounting pronouncements impacting our financial statements.
Recurring fair value measurements	We hold fixed maturity securities and short-term investments, which are carried at fair value. The fair value of fixed maturity securities and short-term investments 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 asset-backed securities), an income or combination 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 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 June 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.
