    This report contains forward-looking statements within the meaning of Section 27A of the Securities Act of 1933, as amended (Securities Act), Section 21E of the Securities Exchange Act of 1934, as amended (Exchange Act), and the U.S. Private Securities Litigation Reform Act of 1995. Any statements about our expectations, outlook, beliefs, plans, predictions, forecasts, objectives, assumptions or future events or performance are not historical facts and may be forward-looking. These statements are often, but not always, made through the use of words or phrases such as “anticipate,” “believe,” “can,” “could,” “may,” “predict,” “assume,” “potential,” “should,” “will,” “estimate,” “perceive,” “plan,” “project,” “continuing,” “ongoing,” “expect,” “intend” or words of similar meaning and include, but are not limited to, statements regarding the outlook for our future business and financial performance.

For more information regarding these risks and uncertainties as well as certain additional risks that we face, you should refer to Part I, Item 2, “Management's Discussion and Analysis of Financial Condition and Results of Operations” and elsewhere in this report on Form 10-Q, including the exhibits hereto. In addition, for additional discussion of those risks and uncertainties that have the potential to affect our business, financial condition, results of operations, cash flows or prospects in a material and adverse manner, you should review Risk Factors in Part II, Item 1A of this Report and in Part I, Item 1A, of our Annual Report on Form 10-K for the year ended December 31, 2023 (2023 10-K), as subsequently updated in other reports we file from time to time with the U.S. Securities and Exchange Commission (SEC).

Unless expressly indicated or the context requires otherwise, the terms “we,” “our,” “us,” “Company” and “NMI” in this document refer to NMI Holdings, Inc., a Delaware corporation, and its wholly-owned subsidiaries on a consolidated basis.

(1)    “Reinsurance funds withheld” has been reclassified as “Other liabilities” in the prior period.

NMI Holdings, Inc. (NMIH) is a Delaware corporation, incorporated in May 2011 to provide private mortgage guaranty insurance (which we refer to as mortgage insurance or MI) through its wholly-owned insurance subsidiaries, National Mortgage Insurance Corporation (NMIC) and National Mortgage Reinsurance Inc One (Re One). Our common stock is listed on the Nasdaq exchange under the ticker symbol “NMIH.”

NMIC, our primary insurance subsidiary, issued its first mortgage insurance policy in April 2013. NMIC is licensed to write mortgage insurance in all 50 states and the District of Columbia (D.C.). Re One historically provided reinsurance coverage to NMIC in accordance with certain statutory risk retention requirements. Such requirements have been repealed and the reinsurance coverage provided by Re One to NMIC has been commuted. Re One remains a wholly-owned, licensed insurance subsidiary; however, it does not currently have active insurance exposures. In August 2015, NMIH capitalized a wholly-owned subsidiary, NMI Services, Inc. (NMIS), through which we offer outsourced loan review services to mortgage loan originators. We operate as a single segment for the purposes of assessing performance and making operating decisions.

The accompanying unaudited condensed consolidated financial statements, which include the results of NMIH and its wholly-owned subsidiaries, have been prepared in accordance with the instructions to Form 10-Q as prescribed by the SEC for interim reporting and include other information and disclosures required by accounting principles generally accepted in the U.S. (GAAP). Our accounts are maintained in U.S. dollars. These statements should be read in conjunction with our consolidated financial statements and notes thereto for the year ended December 31, 2023, included in our 2023 10-K. All intercompany transactions have been eliminated. Certain reclassifications to previously reported financial information have been made to conform to our current period presentation. The preparation of financial statements in accordance with GAAP requires management to make estimates and assumptions that affect reported amounts of assets and liabilities, as well as disclosure of contingent assets and liabilities as of the balance sheet date. Estimates also affect the reported amounts of income and expenses for the reporting period. Actual results could differ from those estimates. The results of operations for the interim period may not be indicative of the results that may be expected for the full year ending December 31, 2024.

There have been no changes to our significant accounting principles as described in Item 8, “Financial Statements and Supplementary Data - Notes to Consolidated Financial Statements - Note 2 - Summary of Accounting Principles” of our 2023 10-K.

In November 2023, the FASB issued ASU 2023-07, Segment Reporting (Topic 280). The update expands annual and interim disclosure requirements for reportable segments, primarily through enhanced disclosures about significant segment expenses. The standard will take effect for all public business entities, including those that have only a single reportable segment for fiscal years beginning after December 15, 2023, and interim periods beginning after December 31, 2024. We are currently evaluating the impact the adoption of this ASU will have, if any, on our consolidated financial statements.

In December 2023, the FASB issued ASU 2023-09, Income Taxes (Topic 740). The update enhances the disclosure requirements related to tax rate reconciliations and income taxes paid. The standard will take effect for public business entities for fiscal years beginning after December 15, 2025. Early adoption is permitted. We are currently evaluating the impact the adoption of this ASU will have, if any, on our consolidated financial statements.

We hold all investments on an available-for-sale basis at fair value on our condensed consolidated balance sheets and evaluate each position quarterly for impairment. We recognize an impairment on a security through the statement of operations if (i) we intend to sell the impaired security; or (ii) it is more likely than not that we will be required to sell the impaired security prior to recovery of its amortized cost basis. If a sale is intended or likely to be required, we recognize an impairment loss equivalent to the difference of the amortized cost basis of the security and its fair value through the condensed consolidated statements of operations and comprehensive income as a “Net Realized Investment Loss.” In the event of an impairment of a security that we intend to and have the ability to hold to maturity, we evaluate the drivers of the impairment to determine the portion that is credit related and the portion that is non-credit related. The portion of impairment loss that is attributed to credit related factors is recognized through the statement of operations as a provision for credit loss and the portion that is attributed to non-credit related factors is recognized in other comprehensive income, net of taxes.

We did not own any mortgage-backed securities in our asset-backed securities portfolio at March 31, 2024 or December 31, 2023.

The following table presents a breakdown of the fair value of our corporate debt securities by issuer industry group as of March 31, 2024 and December 31, 2023:

As of March 31, 2024 and December 31, 2023, approximately $5.2 million and $5.3 million, respectively, of our cash and investments were held in the form of U.S. Treasury securities on deposit with various state insurance departments to satisfy regulatory requirements.

The amortized cost and fair value of available-for-sale securities as of March 31, 2024 and December 31, 2023, by contractual maturity, are shown below. Expected maturities will differ from contractual maturities because issuers may have the right to call or prepay obligations with or without call or prepayment penalties. Because most asset-backed securities provide for periodic payments throughout their lives, they are listed below in a separate category.

As of March 31, 2024, the investment portfolio had gross unrealized losses of $190.2 million, of which $187.5 million were associated with securities that had been in an unrealized loss position for a period of twelve months or longer. As of December 31, 2023, the investment portfolio had gross unrealized losses of $184.3 million, of which $183.1 million were associated with securities that had been in an unrealized loss position for a period of twelve months or longer. For those securities in an unrealized loss position, the length of time the securities were in such a position is as follows:

As of March 31, 2024 and December 31, 2023, we did not recognize an allowance for credit loss for any security in the investment portfolio and we did not record any provision for credit loss for investment securities during the three months ended March 31, 2024 or 2023.

The following table presents the components of net investment income:

(1)    Includes interest income recognized on cash and cash equivalents of $1.1 million and $0.2 million during the three months ended March 31, 2024 and 2023, respectively.

The following table presents the components of net realized investment losses:

The following describes the valuation techniques used by us to determine the fair value of our financial instruments:

We established a fair value hierarchy by prioritizing the inputs to valuation techniques used to measure fair value. The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1 measurements) and the lowest priority to unobservable inputs (Level 3 measurements). The three levels of the fair value hierarchy under this standard are described below:

Level 1 - Fair value measurements based on quoted prices in active markets that we have the ability to access for identical assets or liabilities. Market price data generally is obtained from exchange or dealer markets. We do not adjust the quoted price for such instruments.

Level 2 - Fair value measurements based on inputs other than quoted prices included in Level 1 that are observable for the asset or liability, either directly or indirectly. Level 2 inputs include quoted prices for similar assets and liabilities in active markets, quoted prices for identical or similar assets or liabilities in markets that are not active, and inputs other than quoted prices that are observable for the asset or liability, such as interest rates and yield curves that are observable at commonly quoted intervals.

Level 3 - Fair value measurements based on valuation techniques that use significant inputs that are unobservable. Both observable and unobservable inputs may be used to determine the fair values of positions classified in Level 3. The circumstances for using these measurements include those in which there is little, if any, market activity for the asset or liability. Therefore, we must make certain assumptions, which require significant management judgment or estimation about the inputs a hypothetical market participant would use to value that asset or liability.

In certain cases, the inputs used to measure fair value may fall into different levels of the fair value hierarchy. In such cases, the level in the fair value hierarchy is determined based on the lowest level input that is significant to the fair value measurement in its entirety.

To determine the fair value of securities available-for-sale in Level 1 and Level 2 of the fair value hierarchy, independent pricing sources have been utilized. One price is provided per security based on observable market data. To ensure securities are appropriately classified in the fair value hierarchy, we review the pricing techniques and methodologies of the independent pricing sources and believe that their policies adequately consider market activity, either based on specific transactions for the issue valued or based on modeling of securities with similar credit quality, duration, yield and structure that were recently traded. A variety of inputs are utilized by the independent pricing sources including benchmark yields, reported trades, non-binding broker/dealer quotes, issuer spreads, two sided markets, benchmark securities, bids, offers and reference data including data published in market research publications. Inputs may be weighted differently for any security, and not all inputs are used for each security evaluation. Market indicators, industry and economic events are also considered. This information is evaluated using a multidimensional pricing model. Quality controls are performed by the independent pricing sources throughout this process, which include reviewing tolerance reports, trading information and data changes, and directional moves compared to market moves. This model combines all inputs to arrive at a value assigned to each security. We have not made any adjustments to the prices obtained from the independent pricing sources.

The following tables present the level within the fair value hierarchy at which our financial instruments were measured:

There were no transfers between Level 2 and Level 3 of the fair value hierarchy during the three months ended March 31, 2024, or the year ended December 31, 2023.

On June 19, 2020, we issued $400 million aggregate principal amount of senior secured notes that mature on June 1, 2025 (the Notes) and used a portion of the proceeds from the Notes offering to repay amounts due under our then outstanding $150 million term loan. At March 31, 2024, the Notes were carried at a cost of $398.0 million, net of unamortized debt issuance costs of $2.0 million, and had a fair value of $404.3 million as assessed under our Level 2 hierarchy. At December 31, 2023, the Notes were carried at a cost of $397.6 million, net of unamortized debt issuance costs of $2.4 million, and had a fair value of $401.9 million.

At March 31, 2024, we had $400 million aggregate principal amount of senior secured notes outstanding. The Notes were issued pursuant to an indenture dated June 19, 2020 and bear interest at a rate of 7.375%, payable semi-annually on June 1 and December 1.

The Notes mature on June 1, 2025. We may elect to redeem the Notes in whole or in part at any time prior to March 1, 2025 at a price based on 100% of the aggregate principal amount of any Notes redeemed plus the “Applicable Premium,” plus accrued and unpaid interest thereon. Applicable Premium is defined as the greater of (1) 1.0% of the principal amount of the Notes, or (2) the excess of the present value of the principal value of the Notes plus all future interest payments over the principal amount.

We may elect to redeem the Notes in whole or in part at any time on or after March 1, 2025 at a price equal to 100% of the aggregate principal amount of the Notes to be redeemed plus accrued and unpaid interest thereon.

Interest expense for the Notes includes interest and the amortization of capitalized debt issuance costs. In connection with the Notes offering, we recorded capitalized debt issuance costs of $7.4 million. Such amounts will be amortized over the contractual life of the Notes using the effective interest method. The effective interest rate on the Notes is 7.825%. At March 31, 2024 and December 31, 2023, approximately $2.0 million and $2.4 million, respectively, of unamortized debt issuance costs remained.

At March 31, 2024 and December 31, 2023, $9.8 million and $2.5 million, respectively, of accrued and unpaid interest on the Notes was included in “Accounts Payable and Accrued Expenses” on the condensed consolidated balance sheets.

On November 29, 2021, we amended our $110 million senior secured revolving credit facility (the 2020 Revolving Credit Facility and as amended, the 2021 Revolving Credit Facility), expanding the lender group, increasing the revolving capacity to $250 million, and extending the maturity from February 22, 2023 to the earlier of (x) November 29, 2025, or (y) if any existing senior secured notes remain outstanding on such date, February 28, 2025. Borrowings under the 2021 Revolving Credit Facility may be used for general corporate purposes, including to support the growth of our new business production and operations, and accrue interest at a variable rate equal to, at our discretion, (i) a Base Rate (as defined in the 2021 Revolving Credit Facility) subject to a floor of 1.00% per annum plus a margin of 0.375% to 1.875% per annum, or (ii) the Adjusted Term Secured Overnight Financing Rate (SOFR) (as defined in the 2021 Revolving Credit Facility) plus a margin of 1.375% to 2.875% per annum, with the margin in each of (i) or (ii) based on our applicable corporate credit rating at the time. As of March 31, 2024 and December 31, 2023, no amounts were drawn under the 2021 Revolving Credit Facility.

Under the 2021 Revolving Credit Facility, we are required to pay a quarterly commitment fee on the average daily undrawn amount of 0.175% to 0.525%, based on the applicable corporate credit rating at the time. As of March 31, 2024, the applicable commitment fee was 0.225%. For the three months ended March 31, 2024, we recorded $0.2 million of commitment fees in interest expense.

We incurred debt issuance costs of $1.1 million in connection with the 2021 Revolving Credit Facility and had $0.6 million of unamortized debt issuance costs associated with the 2020 Revolving Credit Facility remaining at the time of its amendment and replacement. Combined unamortized debt issuance costs are amortized through interest expense on a straight-line basis over the contractual life of the 2021 Revolving Credit Facility. At March 31, 2024 and December 31, 2023, remaining unamortized deferred debt issuance costs were $0.7 million and $0.8 million, respectively, in “Other Assets” on our condensed consolidated balance sheets.

We are subject to certain covenants under the 2021 Revolving Credit Facility, including, but not limited to, the following: a maximum debt-to-total capitalization ratio of 35%, compliance with the private mortgage insurer eligibility requirements (PMIERs) financial requirements (subject to any GSE approved waivers), and minimum consolidated net worth and statutory capital requirements (respectively, as defined therein). We were in compliance with all covenants at March 31, 2024.

We enter into third-party reinsurance transactions to actively manage our risk, ensure compliance with PMIERs, state regulatory and other applicable capital requirements, (respectively, as defined therein), and support the growth of our business. The Wisconsin Office of the Commissioner of Insurance (Wisconsin OCI) has approved and the GSEs have indicated their non-objection to all such transactions (subject to certain conditions and ongoing review).

The effect of our reinsurance agreements on premiums written and earned is as follows:

(1)    Net of profit commission.

NMIC is a party to reinsurance agreements with Oaktown Re III Ltd., Oaktown Re V Ltd., Oaktown Re VI Ltd., and Oaktown Re VII Ltd. (special purpose reinsurance entities collectively referred to as the Oaktown Re Vehicles) effective July 30, 2019, October 29, 2020, April 27, 2021, and October 26, 2021, respectively. Each agreement provides NMIC with aggregate excess-of-loss reinsurance coverage on a defined portfolio of mortgage insurance policies. Under each agreement, NMIC retains a first layer of aggregate loss exposure on covered policies and the respective Oaktown Re Vehicle then provides second layer loss protection up to a defined reinsurance coverage amount. NMIC then retains losses in excess of the respective reinsurance coverage amounts.

NMIC makes risk premium payments to the Oaktown Re Vehicles for the applicable outstanding reinsurance coverage amount and pays an additional amount for anticipated operating expenses (capped at $250 thousand per year). NMIC ceded aggregate premiums to the Oaktown Re Vehicles of $6.0 million and $9.1 million during the three months ended March 31, 2024 and 2023, respectively.

NMIC applies claims paid on covered policies against its first layer aggregate retained loss exposure under each excess-of-loss agreement. NMIC did not cede any incurred losses on covered policies to the Oaktown Re Vehicles during the three months ended March 31, 2024 and 2023, as the aggregate first layer risk retention for each applicable agreement was not exhausted during such periods.

Under the terms of each excess-of-loss reinsurance agreement, the Oaktown Re Vehicles are required to fully collateralize their outstanding reinsurance coverage amount to NMIC with funds deposited into segregated reinsurance trusts. Such trust funds are required to be invested in short-term U.S. Treasury money market funds at all times. Each Oaktown Re Vehicle financed its respective collateral requirement through the issuance of mortgage insurance-linked notes to unaffiliated investors. Such insurance-linked notes mature ten years (in the case of the notes issued by Oaktown Re III Ltd. and Oaktown Re V Ltd.) and 12.5 years (in the case of the notes issued by Oaktown Re VI Ltd. and Oaktown Re VII Ltd.) from the inception date of their associated reinsurance agreement. We refer to NMIC’s reinsurance agreements with and the insurance-linked note issuances by Oaktown Re Vehicles individually as the 2019 ILN Transaction, 2020-2 ILN Transaction, 2021-1 ILN Transaction, and 2021-2 ILN Transaction, and collectively as the ILN Transactions.

The respective reinsurance coverage amounts provided by the Oaktown Re Vehicles decrease (over a ten-year period in the case of Oaktown Re III Ltd. and Oaktown Re V Ltd. and 12.5-year period in the case of Oaktown Re VI Ltd. and Oaktown Re VII Ltd.) as the underlying insured mortgages are amortized or repaid, and/or the mortgage insurance coverage is canceled. As the reinsurance coverage decreases, a prescribed amount of collateral held in trust by the Oaktown Re Vehicles is distributed to ILN Transaction noteholders as amortization of the outstanding insurance-linked note principal balances. The outstanding reinsurance coverage amounts stop amortizing, and the distribution of collateral assets to ILN Transaction noteholders and amortization of insurance-linked note principal is suspended if certain credit enhancement or delinquency thresholds, as defined in each agreement, are triggered (each, a Lock-Out Event).

Effective March 31, 2024, a previously triggered Lock-Out Event for the 2019 ILN Transaction was deemed to have cleared and amortization of the associated reinsurance coverage, and distribution of collateral assets and amortization of the associated insurance-linked notes resumed.

(1)    NMIC applies claims paid on covered policies against its first layer aggregate retained loss exposure and cedes reserves for incurred claims and claim expenses to each applicable ILN Transaction and recognizes a reinsurance recoverable if such incurred claims and claim expenses exceed its current first layer retained loss.

(2)    Approximately 1% of the production covered by the 2020-2 ILN Transaction has coverage reporting dates between July 1, 2019 and March 31, 2020.

(3)    Approximately 1% of the production covered by the 2021-1 ILN Transaction has coverage reporting dates between July 1, 2019 and September 30, 2020.

(4)    Approximately 2% of the production covered by the 2021-2 ILN Transaction has coverage reporting dates between July 1, 2019 and March 31, 2021.

Under the terms of our ILN Transactions, we are required to maintain a certain level of restricted funds in premium deposit accounts with Bank of New York Mellon until the respective notes have been redeemed in full. “Cash and Cash Equivalents” on our condensed consolidated balance sheets includes restricted amounts of $1.1 million and $1.3 million as of March 31, 2024 and December 31, 2023, respectively. The restricted balances required under these transactions will decline over time as the outstanding principal balance of the respective insurance-linked notes are amortized.

Under the terms of the XOL Transactions, NMIC makes risk premium payments to its third-party reinsurance providers for the outstanding reinsurance coverage amount and ceded aggregate premiums of $9.2 million and $7.2 million during the three months ended March 31, 2024 and 2023, respectively. NMIC applies claims paid on covered policies against its first layer aggregate retained loss exposure under each agreement. NMIC did not cede any incurred losses on covered policies under the XOL Transactions during the three months ended March 31, 2024 and 2023, as the aggregate first layer risk retention for each agreement was not exhausted during such periods.

NMIC holds optional termination rights which provide it the discretion to terminate each XOL Transaction on or after a specified date. NMIC may also elect to terminate the XOL Transactions at any point if the outstanding reinsurance coverage amount amortizes to 10% or less of the reinsurance coverage amount provided at inception, or if it determines that it will no longer be able to take full PMIERs asset credit for the coverage.

Additionally, under the terms of the treaties, NMIC may selectively terminate its engagement with individual reinsurers under certain circumstances. Such selective termination rights arise when, among other reasons, a reinsurer experiences a deterioration in its capital position below a prescribed threshold, and/or a reinsurer breaches (and fails to cure) its collateral posting obligation.

Each of the third-party reinsurance providers that is party to the XOL Transactions has an insurer financial strength rating of A- or better by S&P Global Ratings (S&P), A.M. Best Company Inc. (A.M. Best) or both.

(1)    NMIC applies claims paid on covered policies against its first layer aggregate retained loss exposure and cedes reserves for incurred claims and claim expenses to each applicable XOL Transaction and recognizes a reinsurance recoverable if such incurred claims and claim expenses exceed its current first layer retained loss.

(2)    Approximately 1% of the production covered by the 2022-1 XOL Transaction has coverage reporting dates between October 21, 2019 and September 30, 2021.

(3)    Approximately 1% of the production covered by the 2022-2 XOL Transaction has coverage reporting dates between January 4, 2021 and March 31, 2022.

(4)    Effective January 1, 2024, the initial reinsurance coverage and initial first layer retained loss amounts increased due to revised contractual terms.

(5)    The initial reinsurance coverage, current reinsurance coverage, initial first layer retained loss and current first layer retained loss for the 2024 XOL Transaction will increase as incremental covered production is ceded under the transaction through December 31, 2024.

Under the terms of the 2016 QSR Transaction, NMIC cedes premiums written related to 20.5% of the risk on eligible primary policies written for all periods through December 31, 2017 and 100% of the risk under our pool agreement with Fannie Mae. The 2016 QSR Transaction is scheduled to terminate on December 31, 2027, except with respect to the ceded pool risk, which expired on August 31, 2023. NMIC has the option, based on certain conditions and subject to a termination fee, to terminate the agreement as of December 31, 2020, or at the end of any calendar quarter thereafter, which could result in NMIC recapturing the related risk.

Under the terms of the 2018 QSR Transaction, NMIC cedes premiums earned related to 25% of the risk on eligible policies written in 2018 and 20% of the risk on eligible policies written in 2019. The 2018 QSR Transaction is scheduled to terminate on December 31, 2029. NMIC has the option, based on certain conditions and subject to a termination fee, to terminate the agreement as of December 31, 2022, or at the end of any calendar quarter thereafter, which could result in NMIC recapturing the related risk.

Under the terms of the 2020 QSR Transaction, NMIC cedes premiums earned related to 21% of the risk on eligible policies written between April 1, 2020 and December 31, 2020. The 2020 QSR Transaction is scheduled to terminate on December 31, 2030. NMIC had the option, based on certain conditions and subject to a termination fee, to terminate the agreement as of December 31, 2025, or at the end of any calendar quarter thereafter, which could result in NMIC recapturing the related risk.

Under the terms of the 2021 QSR Transaction, NMIC cedes premiums earned related to 22.5% of the risk on eligible policies written from January 1, 2021 to October 30, 2021. The 2021 QSR Transaction is scheduled to terminate on December 31, 2031. NMIC has the option, based on certain conditions and subject to a termination fee, to terminate the agreement as of December 31, 2024, or at the end of any calendar quarter thereafter, which could result in NMIC recapturing the related risk.

Under the terms of the 2022 QSR Transaction, NMIC cedes premiums earned related to 20% of the risk on eligible policies written primarily between October 30, 2021 and December 31, 2022. The 2022 QSR Transaction is scheduled to terminate on December 31, 2032. NMIC has the option, based on certain conditions and subject to a termination fee, to terminate the agreement as of December 31, 2024 or semi-annually thereafter, which could result in NMIC recapturing the related risk.

Under the terms of the 2022 Seasoned QSR Transaction, NMIC cedes premiums earned related to 95% of the net risk on eligible policies primarily for a seasoned pool of mortgage insurance policies that had previously been covered under the retired Oaktown Re Ltd. and Oaktown Re IV Ltd. reinsurance transactions, after the consideration of coverage provided by other QSR Transactions. The 2022 Seasoned QSR Transaction is scheduled to terminate on June 30, 2032. NMIC has the option, based on certain conditions, to terminate the agreement as of June 30, 2025 or quarterly thereafter through December 31, 2027 with the payment of a termination fee, and as of March 31, 2028 or quarterly thereafter without the payment of a termination fee. Such termination could result in NMIC recapturing the related risk.

Under the terms of the 2023 QSR Transaction, NMIC cedes premiums earned related to 20% of the risk on eligible policies written in 2023. The 2023 QSR Transaction is scheduled to terminate on December 31, 2033. NMIC has the option, based on certain conditions and subject to a termination fee, to terminate the agreement as of December 31, 2025 or semi-annually thereafter, which could result in NMIC recapturing the related risk.

Under the terms of the 2024 QSR Transaction, NMIC cedes premiums earned related to 20% of the risk on eligible policies written in 2024. The 2024 QSR Transaction is scheduled to terminate on December 31, 2034. NMIC has the option, based on certain conditions and subject to a termination fee, to terminate the agreement as of December 31, 2027, or at the end of any calendar quarter thereafter, which could result in NMIC recapturing the related risk.

NMIC may terminate any or all of the QSR Transactions without penalty if, due to a change in PMIERs requirements, it is no longer able to take full PMIERs asset credit for the risk-in-force (RIF) ceded under the respective agreements. Additionally, under the terms of the QSR Transactions, NMIC may elect to selectively terminate its engagement with individual reinsurers on a run-off basis (i.e., reinsurers continue providing coverage on all risk ceded prior to the termination date, with no new cessions going forward) or cut-off basis (i.e., the reinsurance arrangement is completely terminated with NMIC recapturing all previously ceded risk) under certain circumstances. Such selective termination rights arise when, among other reasons, a reinsurer experiences a deterioration in its capital position below a prescribed threshold and/or a reinsurer breaches (and fails to cure) its collateral posting obligations under the relevant agreement.

The following table shows amounts related to the QSR Transactions:

Ceded premiums written under the 2016 QSR Transaction are recorded as prepaid reinsurance premiums in “Other Assets” on our consolidated balance sheets and amortized to ceded premiums earned in a manner consistent with the recognition of revenue on direct premiums. Under all other QSR Transactions, premiums are ceded on an earned basis as defined in the agreement. NMIC receives a 20% ceding commission for premiums ceded under the QSR Transactions, except with respect to the 2022 Seasoned QSR Transaction under which it receives a 35% ceding commission and the 2020 QSR Transaction under which it receives a 36% ceding commission. NMIC also receives a profit commission under each of the QSR Transactions, provided that the loss ratios on loans covered under the 2016, 2018, 2020, 2021, 2022, 2022 Seasoned, 2023 and 2024 QSR Transactions, generally remain below 60%, 61%, 50%, 57.5%, 62%, 55%, 62% and 56%, respectively, as measured annually. Ceded claims and claim expenses under each of the QSR Transactions reduce the respective profit commission received by NMIC on a dollar-for-dollar basis.

In accordance with the terms of the 2016 QSR Transaction, rather than making a cash payment or transferring investments for ceded premiums written, NMIC established a funds withheld liability, which also includes amounts due to NMIC for ceding and profit commissions. Any loss recoveries and any potential profit commission to NMIC are realized from this account until exhausted. NMIC’s reinsurance recoverable balance is further supported by trust accounts established and maintained by each reinsurer in accordance with the PMIERs funding requirements for risk ceded to non-affiliates. The reinsurance recoverable on loss reserves related to the 2016 QSR Transaction was $1.6 million and $1.7 million as of March 31, 2024 and December 31, 2023, respectively.

In accordance with the terms of the 2018, 2020, 2021, 2022, 2022 Seasoned, 2023 and 2024 QSR Transactions, cash payments for ceded premiums earned are settled on a quarterly basis, offset by amounts due to NMIC for ceding and profit commissions. Any loss recoveries and any potential profit commission to NMIC are also recognized quarterly. NMIC's reinsurance recoverable balance is supported by trust accounts established and maintained by each reinsurer in accordance with the PMIERs funding requirements for risk ceded to non-affiliates. The aggregate reinsurance recoverable on loss reserves related to the 2018, 2020, 2021, 2022, 2022 Seasoned, 2023, and 2024 QSR Transactions was $26.3 million and $25.8 million as of March 31, 2024 and December 31, 2023, respectively.

We remain directly liable for all claim payments if we are unable to collect the recoverables due from our reinsurers and, as such, we actively monitor and manage our counterparty credit exposure to our reinsurance providers. We establish an allowance for expected credit loss against our reinsurance recoverable if we do not expect to recover amounts due from one or more of our reinsurance counterparties, and report our reinsurance recoverable net of such allowance, if any. We actively monitor the counterparty credit profiles of our reinsurers and each is required to partially collateralize its obligations under the terms of the QSR Transactions. The allowance for credit loss established against our reinsurance recoverable was deemed immaterial as of March 31, 2024 and December 31, 2023.

We hold gross reserves in an amount equal to the estimated liability for insurance claims and claim expenses related to defaults on insured mortgage loans. A loan is considered to be in “default” as of the payment date at which a borrower has missed the preceding two or more consecutive monthly payments. We establish reserves for loans that have been reported to us in default by servicers, referred to as case reserves, and additional loans that we estimate (based on actuarial review and other factors) to be in default that have not yet been reported to us by servicers, referred to as incurred but not reported (IBNR) reserves. We also establish reserves for claim expenses, which represent the estimated cost of the claim administration process, including legal and other fees, as well as other general expenses of administering the claim settlement process. As of March 31, 2024, we held gross reserves for insurance claims and claim expenses of $127.2 million. During the three months ended March 31, 2024, we paid 42 claims totaling $1.1 million, including 41 claims covered under the QSR Transactions representing $0.3 million of ceded claims and claim expenses.

We had 5,109 loans in default in our primary insured portfolio as of March 31, 2024, which represented a 0.80% default rate against 635,662 total policies in-force and 5,099 loans in default in our primary portfolio as of December 31, 2023, which represented a 0.81% default rate against 629,690 total policies in-force. The size of the reserve we establish for each defaulted loan (and by extension our aggregate reserve for claims and claim expenses) reflects our best estimate of the future claim payment to be made for each individual loan in default. Our future claims exposure is a function of the number of defaulted loans that progress to claim payment (which we refer to as frequency) and the amount to be paid to settle such claims (which we refer to as severity). Our estimates of claims frequency and severity are not formulaic, rather they are broadly synthesized based on historical observed experience for similarly situated loans and assumptions about future macroeconomic factors.

(1)    Related to ceded losses recoverable under the QSR Transactions. See Note 5, “Reinsurance” for additional information.

(2)    Related to insured loans with their most recent defaults occurring in the current year. For example, if a loan defaulted in a prior year and subsequently cured and later re-defaulted in the current year, the default would be included in the current year. Amounts are presented net of reinsurance and included $25.9 million attributed to net case reserves and $6.6 million attributed to net IBNR reserves for the three months ended March 31, 2024 and $22.3 million attributed to net case reserves and $4.9 million attributed to net IBNR reserves for the three months ended March 31, 2023.

(3)    Related to insured loans with defaults occurring in prior years, which have been continuously in default before the start of the current year. Amounts are presented net of reinsurance and included $22.4 million attributed to net case reserves and $6.3 million attributed to net IBNR reserves for the three months ended March 31, 2024 and $16.2 million attributed to net case reserves and $4.5 million attributed to net IBNR reserves for the three months ended March 31, 2023.

The “claims incurred” section of the table above shows claims and claim expenses incurred on defaults occurring in current and prior years, including IBNR reserves, and is presented net of reinsurance. The amount of claims incurred relating to current year defaults increased during the three months ended March 31, 2024, compared to the same period in the prior year, primarily due to an increase in the total number of new delinquencies emerging during the period tied to the growth and natural seasoning of our portfolio, partially offset by a decrease in the average case reserve established against newly defaulted loans. Our provision for claims and claim expenses during both the three months ended March 31, 2024 and 2023 benefited from favorable development on prior year defaults. We recognized $29.3 million and $20.9 million of favorable prior year development during the three months ended March 31, 2024 and 2023, respectively, primarily due to cure activity and ongoing analysis of recent loss development trends. We may increase or decrease our claim estimates and reserves as we learn additional information about individual defaulted loans, and continue to observe and analyze loss development trends in our portfolio. Gross reserves of $85.1 million related to prior year defaults remained as of March 31, 2024.

Basic EPS is based on the weighted average number of shares of common stock outstanding. Diluted EPS is based on the weighted average number of shares of common stock outstanding and common stock equivalents that would be issuable upon the vesting of service-based and performance and service-based restricted stock units (RSUs), and the exercise of vested and unvested stock options.

The following table reconciles the net income and the weighted average shares of common stock outstanding used in the computations of basic and diluted EPS of common stock:

We are a U.S. taxpayer and are subject to a statutory U.S. federal corporate income tax rate of 21%. Taxable income is reported on our consolidated U.S. federal and various state income tax returns, filed by NMIH on behalf of itself and its subsidiaries. Our effective tax rate on our pre-tax income was 22.3% and 22.6% for the three months ended March 31, 2024 and 2023, respectively. Our provision for income taxes for interim reporting periods is established based on our estimated annual effective tax rate for a given year. Our effective tax rate may fluctuate between interim periods due to the impact of discrete items not included in our estimated annual effective tax rate, including the tax effects associated with the vesting of RSUs and exercise of options. Such items are treated on a discrete basis in the reporting period in which they occur.

As a mortgage guaranty insurance company, we are eligible to claim a tax deduction for our statutory contingency reserve balance, subject to certain limitations outlined under IRC Section 832(e), and only to the extent we acquire tax and loss bonds in an amount equal to the tax benefit derived from the claimed deduction, which is our intent. As a result, our interim provision for income taxes for the three months ended March 31, 2024 primarily represents a change in our net deferred tax liability. As of March 31, 2024 and December 31, 2023, we held $235.3 million of tax and loss bonds in “Prepaid Federal Income Taxes” on our condensed consolidated balance sheets.

On February 10, 2022, our Board of Directors authorized a $125 million share repurchase program (excluding associated costs and applicable taxes) effective through December 31, 2023. On July 31, 2023, our Board of Directors authorized a new $200 million share repurchase program (excluding associated costs and applicable taxes) effective through December 31, 2025. Concurrent with the new authorization, our Board of Directors also approved an extension of our existing $125 million share repurchase program through December 31, 2025 to align its remaining tenor with that of the $200 million program. The authorization provides us the flexibility, based on market and business conditions, stock price and other factors, to repurchase stock from time to time through open market purchases, privately negotiated transactions, or other means, including pursuant to Rule 10b5-1 trading plans.

During the three months ended March 31, 2024, we repurchased 0.8 million shares at an average price of $29.98 per share (excluding associated costs and applicable taxes). During the year ended December 31, 2023, we repurchased 3.5 million shares at an average price of $25.93 per share (excluding associated costs and applicable taxes). As of March 31, 2024, we had $151.8 million of repurchase authority remaining under our current program.

We record a litigation liability when we determine that it is probable a litigation loss will be incurred and the amount of such anticipated loss can be reasonably estimated. In the event we determine that a litigation loss is reasonably possible (though not probable), we disclose an estimate of the possible loss if such estimate can be reasonably established or disclose the matter with no estimate if such estimate cannot be reasonably made. We evaluate litigation and other legal developments that could affect our accrual for probable losses or our estimated disclosure of possible losses and make ongoing adjustments to our accruals and disclosures as appropriate.

Significant judgment is required to determine both the likelihood and the estimated amount of potential losses related to such matters.

We are currently named as a defendant in a litigation proceeding pertaining to the refund of certain mortgage insurance premiums under the Homeowners Protection Act. The case was dismissed in September 2023 and is currently pending appeal. We do not currently expect that we will incur a material loss in connection with the case and have not recorded a litigation liability for this matter.

Premiums receivable consists of premiums due on our mortgage insurance policies. If a mortgage insurance premium is unpaid for more than 120 days, the associated receivable is written off against earned premium and the related insurance policy is canceled. Premiums receivable may be written off prior to 120 days in the ordinary course of business for non-credit events including, but not limited to, the modification or refinancing of an underlying insured loan. We established a $2.3 million and $2.7 million reserve for premium write-offs at March 31, 2024 and December 31, 2023, respectively.

We separately recognize an allowance for credit losses for premiums receivable based on credit losses expected to arise over the life of the receivable. Due to the nature of our insurance policies (a necessary precondition for access to mortgage credit for covered borrowers) and the short duration of the related receivables, we do not typically experience credit losses against our premium receivables and the allowance for credit loss established on premium receivable was deemed immaterial at March 31, 2024 and December 31, 2023.

Our insurance subsidiaries, NMIC and Re One, file financial statements in conformity with statutory accounting principles (SAP) prescribed or permitted by the Wisconsin OCI, NMIC's principal regulator. Prescribed SAP includes state laws, regulations and general administrative rules, as well as a variety of publications of the National Association of Insurance Commissioners (NAIC). The Wisconsin OCI recognizes only statutory accounting practices prescribed or permitted by the state of Wisconsin for determining and reporting the financial condition and results of operations of an insurance company and for determining its solvency under Wisconsin insurance laws.

NMIC and Re One generated combined statutory net income of $34.7 million and $21.8 million for the three months ended March 31, 2024 and 2023, respectively.

The Wisconsin OCI has imposed a prescribed accounting practice for the treatment of statutory contingency reserves that differs from the treatment promulgated by the NAIC. Under Wisconsin OCI's prescribed practice mortgage guaranty insurers are required to reflect changes in their contingency reserves through statutory income. Such approach contrasts with the NAIC's treatment, which records changes to contingency reserves directly to unassigned funds. As a Wisconsin-domiciled insurer, NMIC's statutory net income reflects an expense associated with the change in its contingency reserve. While such treatment impacts NMIC's statutory net income, it does not have an effect on NMIC's statutory capital position.

The following table presents NMIC's statutory surplus, contingency reserve, statutory capital and risk-to-capital (RTC) ratio as of March 31, 2024 and December 31, 2023.

(1)    Represents the total of the statutory surplus and contingency reserve.

Re One had $2.1 million and $2.0 million of statutory capital at March 31, 2024 and December 31, 2023, respectively.

NMIH is not subject to any limitations on its ability to pay dividends except those generally applicable to corporations that are incorporated in Delaware.

Delaware law provides that dividends are only payable out of a corporation's capital surplus or, subject to certain limitations, recent net profits.

NMIC and Re One are subject to certain rules and regulations prescribed by jurisdictions in which they are authorized to operate and the GSEs that may restrict their ability to pay dividends to NMIH. NMIC has the capacity to pay $96.3 million of aggregate ordinary dividends to NMIH during the twelve-month period ending December 31, 2024.

On April 29, 2024, we entered into a new $250 million five-year unsecured revolving credit facility (the 2024 Revolving Credit Facility) to replace, upon close, our existing 2021 (secured) Revolving Credit Facility. Borrowings under the 2024 Revolving Credit Facility may be used for general corporate purposes, including to support growth, new business production and operations, and will accrue interest and carry undrawn commitment fees identical to those incurred under the 2021 Revolving Credit Facility. Under the 2024 Revolving Credit Facility we will be subject to certain covenants, including a maximum debt-to-total capitalization ratio of 35%, compliance with the PMIERs financial requirements (subject to any GSE approved waivers), and a minimum consolidated net worth requirement (as defined therein). We will no longer be subject to a minimum statutory capital covenant. Closing of the 2024 Revolving Credit Facility is subject to the satisfaction of certain terms and conditions contained therein.

We provide private MI through our primary insurance subsidiary, NMIC. NMIC is wholly-owned, domiciled in Wisconsin and principally regulated by the Wisconsin OCI. NMIC is approved as an MI provider by the GSEs and is licensed to write coverage in all 50 states and D.C. Our subsidiary, NMIS, provides outsourced loan review services to mortgage loan originators and our subsidiary, Re One, historically provided reinsurance coverage to NMIC in accordance with certain statutory risk retention requirements. Such requirements have been repealed and the reinsurance coverage provided by Re One to NMIC has been commuted. Re One remains a wholly-owned, licensed insurance subsidiary; however, it does not currently have active insurance exposures.

MI protects lenders and investors from default-related losses on a portion of the unpaid principal balance of a covered mortgage. MI plays a critical role in the U.S. housing market by mitigating mortgage credit risk and facilitating the secondary market sale of high- loan-to-value (LTV) (i.e., above 80%) residential loans to the GSEs, who are otherwise restricted by their charters from purchasing or guaranteeing high-LTV mortgages that are not covered by certain credit protections. Such credit protection and secondary market sales allow lenders to increase their capacity for mortgage commitments and expand financing access to existing and prospective homeowners.

NMIH, a Delaware corporation, was incorporated in May 2011, and we began start-up operations in 2012 and wrote our first MI policy in 2013. Since formation, we have sought to establish customer relationships with a broad group of mortgage lenders and build a diversified, high-quality insured portfolio. As of March 31, 2024, we had issued master policies with 1,984 customers, including national and regional mortgage banks, money center banks, credit unions, community banks, builder-owned mortgage lenders, internet-sourced lenders and other non-bank lenders. As of March 31, 2024, we had $199.4 billion of primary insurance-in-force (IIF) and $52.6 billion of primary risk-in-force (RIF).

We believe that our success in acquiring a large and diverse group of lender customers and growing a portfolio of high-quality IIF traces to our founding principles, whereby we aim to help qualified individuals achieve their homeownership goals, ensure that we remain a strong and credible counter-party, deliver a high-quality customer service experience, establish a differentiated risk management approach that emphasizes the individual underwriting review or validation of the vast majority of the loans we insure, utilizing our proprietary Rate GPS® pricing platform to dynamically evaluate risk and price our policies, and foster a culture of collaboration and excellence that helps us attract and retain experienced industry leaders.

Our strategy is to continue to build on our position in the private MI market, expand our customer base and grow our insured portfolio of high-quality residential loans by focusing on long-term customer relationships, disciplined and proactive risk selection and pricing, fair and transparent claim payment practices, responsive customer service, and financial strength and profitability.

Our common stock trades on the Nasdaq under the symbol “NMIH.” Our headquarters is located in Emeryville, California. As of March 31, 2024, we had 234 employees. Our corporate website is located at www.nationalmi.com. Our website and the information contained on or accessible through our website are not incorporated by reference into this report.

We discuss below our results of operations for the periods presented, as well as the conditions and trends that have impacted or are expected to impact our business, including new insurance writings, the composition of our insurance portfolio and other factors that we expect to impact our results.

Macroeconomic factors, including persistent inflation, elevated interest rates, flagging consumer confidence and increasing jobless claims could have a pronounced impact on the housing market, the mortgage insurance industry and our business in future periods. A marked decline in housing demand, a significant and protracted decrease in house prices or a sustained increase in unemployment could reduce the pace of new business activity in the private mortgage insurance market and negatively impact our future new insurance written (NIW) volume, or contribute to an increase in our future default and claim experience.

NIW is the aggregate unpaid principal balance of mortgages underpinning new policies written during a given period. Our NIW is affected by the overall size of the mortgage origination market and the volume of high-LTV mortgage originations. Our NIW is also affected by the percentage of such high-LTV originations covered by private versus government MI or other alternative credit enhancement structures and our share of the private MI market. NIW, together with persistency, drives our IIF. IIF is the aggregate unpaid principal balance of the mortgages we insure, as reported to us by servicers at a given date, and represents the sum total of NIW from all prior periods less principal payments on insured mortgages and policy cancellations (including for prepayment, nonpayment of premiums, coverage rescission and claim payments). RIF is related to IIF and represents the aggregate amount of coverage we provide on all outstanding policies at a given date. RIF is calculated as the sum total of the coverage percentage of each individual policy in our portfolio applied to the unpaid principal balance of such insured mortgage. RIF is affected by IIF and the LTV profile of our insured mortgages, with lower LTV loans generally having a lower coverage percentage and higher LTV loans having a higher coverage percentage. Gross RIF represents RIF before consideration of reinsurance. Net RIF is gross RIF net of ceded reinsurance.

We set our premium rates on individual policies based on the risk characteristics of the underlying mortgage loans and borrowers, and in accordance with our filed rates and applicable rating rules. On June 4, 2018, we introduced a proprietary risk-based pricing platform, which we refer to as Rate GPS®. Rate GPS® considers a broad range of individual variables, including property type, type of loan product, borrower credit characteristics, and lender and market factors, and provides us with the ability to set and charge premium rates commensurate with the underlying risk of each loan that we insure. We introduced Rate GPS® in June 2018 to replace our previous rate card pricing system. While most of our new business is priced through Rate GPS®, we also continue to offer a rate card pricing option to a limited number of lender customers who require a rate card for operational reasons. We believe the introduction and utilization of Rate GPS® provides us with a more granular and analytical approach to evaluating and pricing risk, and that this approach enhances our ability to continue building a high-quality mortgage insurance portfolio and delivering attractive risk-adjusted returns.

Premiums are generally fixed for the duration of our coverage of the underlying loans. Net premiums written are equal to gross premiums written minus ceded premiums written under our reinsurance arrangements, less premium refunds and premium write-offs. As a result, net premiums written are generally influenced by:

•NIW;

•premium rates and the mix of premium payment type, which are either single, monthly or annual premiums, as described below;

•cancellation rates of our insurance policies, which are impacted by payments or prepayments on mortgages, refinancings (which are affected by prevailing mortgage interest rates as compared to interest rates on loans underpinning our in force policies), levels of claim payments and home prices; and

•cession of premiums under third-party reinsurance arrangements.

Premiums are paid either by the borrower (borrower-paid mortgage insurance or BPMI) or the lender (lender-paid mortgage insurance or LPMI) in a single payment at origination (single premium), on a monthly installment basis (monthly premium) or on an annual installment basis (annual premium). Our net premiums written will differ from our net premiums earned due to policy payment type. For single premiums, we receive a single premium payment at origination, which is earned over the estimated life of the policy. Substantially all of our single premium policies in force as of March 31, 2024 were non-refundable under most cancellation scenarios.

If non-refundable single premium policies are canceled, we immediately recognize the remaining unearned premium balances as earned premium revenue. Monthly premiums are recognized in the month billed and when the coverage is effective. Annual premiums are earned on a straight-line basis over the year of coverage. Substantially all of our policies provide for either single or monthly premiums.

The percentage of IIF that remains on our books after any twelve-month period is defined as our persistency rate. Because our insurance premiums are earned over the life of a policy, higher persistency rates can have a significant impact on our net premiums earned and profitability. Generally, faster speeds of mortgage prepayment lead to lower persistency. Prepayment speeds and the relative mix of business between single and monthly premium policies also impact our profitability. Our premium rates include certain assumptions regarding repayment or prepayment speeds of the mortgages underlying our policies. Because premiums are paid at origination on single premium policies and our single premium policies are generally non-refundable on cancellation, assuming all other factors remain constant, if single premium loans are prepaid earlier than expected, our profitability on these loans is likely to increase and, if loans are repaid slower than expected, our profitability on these loans is likely to decrease. By contrast, if monthly premium loans are repaid earlier than anticipated, we do not earn any more premium with respect to those loans and, unless we replace the repaid monthly premium loan with a new loan at the same premium rate or higher, our revenue is likely to decline.

We utilize third-party reinsurance to actively manage our risk, ensure compliance with PMIERs, state regulatory and other applicable capital requirements, and support the growth of our business. We currently have both quota share and excess-of-loss reinsurance agreements in place, which impact our results of operations and regulatory capital and PMIERs asset positions. Under a quota share reinsurance agreement, the reinsurer receives a premium in exchange for covering an agreed-upon portion of incurred losses. Such a quota share arrangement reduces premiums written and earned and also reduces RIF, providing capital relief to the ceding insurance company and reducing incurred claims in accordance with the terms of the reinsurance agreement. In addition, reinsurers typically pay ceding commissions as part of quota share transactions, which offset the ceding company's acquisition and underwriting expenses. Certain quota share agreements include profit commissions that are earned based on loss performance and serve to reduce ceded premiums. Under an excess-of-loss agreement, the ceding insurer is typically responsible for losses up to an agreed-upon threshold and the reinsurer then provides coverage in excess of such threshold up to a maximum agreed-upon limit. We expect to continue to evaluate reinsurance opportunities in the normal course of business.

NMIC is party to reinsurance agreements with the Oaktown Re Vehicles that provide it with aggregate excess-of-loss reinsurance coverage on defined portfolios of mortgage insurance policies. Under each agreement, NMIC retains a first layer of aggregate loss exposure on covered policies and the respective Oaktown Re Vehicle then provides second layer loss protection up to a defined reinsurance coverage amount. NMIC then retains losses in excess of the respective reinsurance coverage amounts.

The respective reinsurance coverage amounts provided by the Oaktown Re Vehicles decrease (over a ten-year period in the case of Oaktown Re III Ltd. and Oaktown Re V Ltd. and 12.5-year period in the case of Oaktown Re VI Ltd. and Oaktown Re VII Ltd.) as the underlying insured mortgages are amortized or repaid, and/or the mortgage insurance coverage is canceled. As the reinsurance coverage decreases, a prescribed amount of collateral held in trust by the Oaktown Re Vehicles is distributed to ILN Transaction noteholders as amortization of the outstanding insurance-linked note principal balances. The outstanding reinsurance coverage amounts stop amortizing, and the distribution of collateral assets to ILN Transaction noteholders and amortization of insurance-linked note principal is suspended if certain credit enhancement or delinquency thresholds, as defined in each agreement, are triggered (each, a Lock-Out Event). Effective March 31, 2024, a previously triggered Lock-Out Event for the 2019 ILN Transaction was deemed to have cleared and amortization of the associated reinsurance coverage, and distribution of collateral assets and amortization of the associated insurance-linked notes resumed.

(1)    NMIC applies claims paid on covered policies against its first layer aggregate retained loss exposure and cedes reserves for incurred claims and claim expenses to each applicable ILN Transaction and recognizes a reinsurance recoverable if such incurred claims and claim expenses exceed its current first layer retained loss.

(2)    Approximately 1% of the production covered by the 2020-2 ILN Transaction has coverage reporting dates between July 1, 2019 and March 31, 2020.

(3)    Approximately 1% of the production covered by the 2021-1 ILN Transaction has coverage reporting dates between July 1, 2019 and September 30, 2020.

(4)    Approximately 2% of the production covered by the 2021-2 ILN Transaction has coverage reporting dates between July 1, 2019 and March 31, 2021.

NMIC holds optional termination rights which provide it the discretion to terminate each XOL Transaction on or after a specified date. NMIC may also elect to terminate the XOL Transactions at any point if the outstanding reinsurance coverage amount amortizes to 10% or less of the reinsurance coverage amount provided at inception, or if it determines that it will no longer be able to take full PMIERs asset credit for the coverage. Additionally, under the terms of the treaties, NMIC may selectively terminate its engagement with individual reinsurers under certain circumstances. Such selective termination rights arise when, among other reasons, a reinsurer experiences a deterioration in its capital position below a prescribed threshold, and/or a reinsurer breaches (and fails to cure) its collateral posting obligation.

Each of the third-party reinsurance providers that is party to the XOL Transactions has an insurer financial strength rating of A- or better by S&P, A.M. Best or both.

(1)    NMIC applies claims paid on covered policies against its first layer aggregate retained loss exposure and cedes reserves for incurred claims and claim expenses to each applicable XOL Transaction and recognizes a reinsurance recoverable if such incurred claims and claim expenses exceed its current first layer retained loss.

(2)    Approximately 1% of the production covered by the 2022-1 XOL Transaction has coverage reporting dates between October 21, 2019 and September 30, 2021.

(3)    Approximately 1% of the production covered by the 2022-2 XOL Transaction has coverage reporting dates between January 4, 2021 and March 31, 2022.

(4)    Effective January 1, 2024, the initial reinsurance coverage and initial first layer retained loss amounts increased due to revised contractual terms.

Under the terms of the 2016 QSR Transaction, NMIC cedes premiums written related to 20.5% of the risk on eligible primary policies written for all periods through December 31, 2017 in exchange for reimbursement of ceded claims and claim expenses on covered policies, a 20% ceding commission, and a profit commission of up to 60% that varies directly and inversely with ceded claims. NMIC previously ceded 100% of the risk under its pool agreement with Fannie Mae; however, such agreement expired on August 31, 2023 and NMIC no longer cedes pool risk under the 2016 QSR Transaction.

Under the terms of the 2018 QSR Transaction, NMIC cedes premiums earned related to 25% of the risk on eligible policies written in 2018 and 20% of the risk on eligible policies written in 2019, in exchange for reimbursement of ceded claims and claim expenses on covered policies, a 20% ceding commission, and a profit commission of up to 61% that varies directly and inversely with ceded claims.

Under the terms of the 2020 QSR Transaction, NMIC cedes premiums earned related to 21% of the risk on eligible policies written between April 1, 2020 and December 31, 2020, in exchange for reimbursement of ceded claims and claim expenses on covered policies, a 36% ceding commission, and a profit commission of up to 50% that varies directly and inversely with ceded claims.

Under the terms of the 2021 QSR Transaction, NMIC cedes premiums earned related to 22.5% of the risk on eligible policies written in 2021 (subject to an aggregate risk written limit which was exhausted on October 30, 2021), in exchange for reimbursement of ceded claims and claim expenses on covered policies, a 20% ceding commission, and a profit commission of up to 57.5% that varies directly and inversely with ceded claims.

Under the terms of the 2022 QSR Transaction, NMIC cedes premiums earned related to 20% of the risk on eligible policies written between October 30, 2021 and December 31, 2022, in exchange for reimbursement of ceded claims and claim expenses on covered policies, a 20% ceding commission, and a profit commission of up to 62% that varies directly and inversely with ceded claims.

Under the terms of the 2022 Seasoned QSR Transaction, NMIC cedes premiums earned related to 95% of the net risk on eligible policies primarily for a seasoned pool of mortgage insurance policies that had previously been covered under the retired Oaktown Re Ltd. and Oaktown Re IV Ltd. reinsurance transactions, after the consideration of coverage provided by other QSR Transactions, in exchange for reimbursement of ceded claims and claim expenses on covered policies, a 35% ceding commission, and a profit commission of up to 55% that varies directly and inversely with ceded claims.

Under the terms of the 2023 QSR Transaction, NMIC cedes premiums earned related to 20% of the risk on eligible policies written in 2023, in exchange for reimbursement of ceded claims and claim expenses on covered policies, a 20% ceding commission, and a profit commission of up to 62% that varies directly and inversely with ceded claims.

Under the terms of the 2024 QSR Transaction, NMIC cedes premiums earned related to 20% of the risk on eligible policies written in 2024, in exchange or reimbursement of ceded claims and claim expenses on covered policies, a 20% ceding commission, and a profit commission of up to 56% that varies directly and inversely with ceded claims.

NMIC may terminate any or all of the QSR Transactions without penalty if, due to a change in PMIERs requirements, it is no longer able to take full PMIERs asset credit for the RIF ceded under the respective agreements. Additionally, under the terms of the QSR Transactions, NMIC may elect to selectively terminate its engagement with individual reinsurers on a run-off basis (i.e., reinsurers continue providing coverage on all risk ceded prior to the termination date, with no new cessions going forward) or cut-off basis (i.e., the reinsurance arrangement is completely terminated with NMIC recapturing all previously ceded risk) under certain circumstances. Such selective termination rights arise when, among other reasons, a reinsurer experiences a deterioration in its capital position below a prescribed threshold and/or a reinsurer breaches (and fails to cure) its collateral posting obligations under the relevant agreement.

See Item 1, “Financial Statements - Notes to Condensed Consolidated Financial Statements - Note 5, Reinsurance” for further discussion of these third-party reinsurance arrangements.

The following table presents NIW and primary and pool IIF as of the dates and for the periods indicated. Unless otherwise noted, the tables below do not include the effects of our third-party reinsurance arrangements described above.

NIW increased 8% to $9.4 billion for the three months ended March 31, 2024 compared to $8.7 billion for the three months ended March 31, 2023, primarily due to the growth in our customer franchise and market presence tied to the increased penetration of existing customer accounts and new customer activations.

Primary IIF increased 7% at March 31, 2024 compared to March 31, 2023, primarily due to the NIW generated between such measurement dates, partially offset by the run-off of in-force policies. Our persistency rate improved to 85.8% at March 31, 2024 from 85.1% at March 31, 2023, and remains historically high due to a continued slowdown in the pace of mortgage refinancing activity tied to the prevailing interest and mortgage rate environment.

The following table presents net premiums written and earned for the periods indicated:

Net premiums written and earned increased 15% and 12%, respectively, during the three months ended March 31, 2024 compared to the three months ended March 31, 2023, primarily driven by growth in our monthly IIF and monthly pay premium receipts, as well as a decline in the total premiums ceded under our reinsurance treaties. The growth in net premiums earned was partially offset by a decline in the contribution from single premium policy cancellations.

Unless otherwise noted, the portfolio statistics tables presented below do not include the effects of our third-party reinsurance arrangements described above. The table below highlights trends in our primary portfolio as of the dates and for the periods indicated.

(1)    Reported as of the end of the period.

(2)    Calculated as end of period RIF divided by end of period IIF.

(3)    Calculated as net premiums earned divided by average primary IIF for the period, annualized.

(4)    Defined as the percentage of IIF that remains on our books after a given twelve-month period.

(5)    Defined as the percentage of IIF that is no longer on our books after a given three-month period.

The table below presents a summary of the change in total primary IIF for the dates and periods indicated.

We consider a “book” to be a collective pool of policies insured during a particular period, normally a calendar year. In general, the majority of underwriting profit, calculated as earned premium revenue minus claims and underwriting and operating expenses, generated by a particular book year emerges in the years immediately following origination. This pattern generally occurs because relatively few of the claims that a book will ultimately experience typically occur in the first few years following origination, when premium revenue is highest, while subsequent years are affected by declining premium revenues, as the number of insured loans decreases (primarily due to loan prepayments), and by increasing losses.

The table below presents a summary of our primary IIF and RIF by book year as of the dates indicated.
