1. Organization, Basis of Presentation and Summary of Accounting Principles
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).
In April 2012, we completed a private placement of our securities, through which we offered and sold an aggregate of 55 million of our Class A Our common stock resulting in net proceeds of approximately $510 million (the Private Placement), and we completed the acquisition of our insurance subsidiaries for $8.5 million in cash, common stock and warrants, plus the assumption of $1.3 million in liabilities. In November 2013, we completed an initial public offering of 2.4 million shares of our common stock, and our common stock began tradingis listed on the NASDAQ exchange on November 8, 2013, under the ticker symbol "NMIH." In March 2018, we completed the sale of an additional 4.3 million shares of common stock including a 15% option to purchase additional shares, which was exercised in full.
In April 2013, NMIC, our primary insurance subsidiary, issued its first mortgage insurance policy. NMIC is licensed to write mortgage insurance in all 50 states and D.C. 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.
Basis of Presentation
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, 2017,2018, included in our 20172018 10-K. All intercompany transactions have been eliminated. 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. Certain reclassifications to our previously reported financial information have been made to conform to current period presentation. 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, 2018.2019.
Significant Accounting Principles
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 2017 Form2018 10-K, other than as noted in "Reinsurance", "Variable interest entity"entities" and "Recent Accounting Pronouncements - Adopted"Adopted" below.
ReinsuranceVariable Interest Entities
We account for premiums, claims and claim expenses that are cededNMIC is a party to reinsurers on a basis consistent with those we use to account for the original policies we issue and pursuant to the terms of our reinsurance contracts. We account for premiums ceded or otherwise paid to reinsurers as reductions to premium revenue.
Effective January 1, 2018, NMIC entered into a second quota share reinsurance transaction (2018 QSR Transaction) which is similar in nature to the quota share reinsurance transaction we entered into in September 2016 (2016 QSR Transaction, together with 2018 QSR Transaction, the QSR Transactions) (see Note 5, "Reinsurance"). We earn profit and ceding commissions in connection with the QSR Transactions.  Profit commissions represent a percentage of the profits recognized by reinsurers that are returned to us, based on the level of claims and claim expenses that we cede. We recognize any profit commissions we earn as increases to premium revenue. Ceding commissions are calculated as a percentage of ceded written premiums under the 2016 QSR Transaction and as a percentage of ceded earned premiums under the 2018 QSR Transaction, to cover our costs to acquire and service the direct policies. We earn the ceding commissions in a manner consistent with our recognition of earnings on the underlying insurance policies, over the terms of the policies reinsured. We account for ceding commissions earned as a reduction to underwriting and operating expenses. 
Under the QSR Transactions, we cede a portion of claims and claim expenses reserves to our reinsurers, which are accounted for as reinsurance recoverables in "Other Assets" on the consolidated balance sheets and as reductions to claim expense on the consolidated statements of operations. We remain directly liable for all loss payments in the event we are unable to collect from any reinsurer.

Variable interest entity
NMIC entered into aggregate excess of loss reinsurance agreements with 3 special purpose reinsurance entities - Oaktown Re Ltd. (Oaktown Re), Oaktown Re II Ltd. and Oaktown Re II Ltd (Oaktown Re II), each a Bermuda-domiciled special purpose reinsurer, inIII Ltd. - respectively dated May 2, 2017, July 25, 2018 and August 2018, respectively.July 30, 2019. At inception of eachthe respective reinsurance agreement,agreements, we determined that each of Oaktown Re Ltd., Oaktown Re II, Ltd. and Oaktown Re IIIII, Ltd, were variable interest entities (VIEs), as defined under GAAP (ASC 810),Accounting Standards Codification (ASC) 810, because they did not have sufficient equity at risk to finance their respective activities. We evaluated the VIEs at inception to determine whether NMIC was the primary beneficiary under each deal and, if so, whether we were required to consolidate the assets and liabilities of each VIE. The primary beneficiary of a VIE is an enterprise that (1) has the power to direct the activities of the VIE, which most significantly impact its economic performance and (2) has significant economic exposure to the VIE; VIE, i.e., the obligation to absorb losses or receive benefits that could potentially be significant. The determination of whether an entity is the primary beneficiary of a VIE is complex and requires management judgment regarding determinative factors, including the expected results of the VIE and how those results are absorbed by beneficial interest holders, as well as which party has the power to direct activities that most significantly impact the performance of the VIE.
We concluded that we are not the primary beneficiary of either Oaktown Re or Oaktown Re II because NMIC does not have significant economic exposure to either Oaktown Re or Oaktown Re II,each VIE and as such, we do not consolidate the VIEsthem in our consolidated financial statements.
Recent Accounting Pronouncements - Adopted
In May 2014,February 2016, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) 2014-09, Revenue from Contracts with Customers (Topic 606). This update is intended to provide a consistent approach in recognizing revenue. In December 2016, the FASB clarified that all contracts that are within the scope of Topic 944, Financial Services-Insurance, are excluded from the scope of ASU 2014-09. Accordingly, this update did not impact the recognition of revenue related to insurance premiums or investment income, which represent a majority of our total revenues. The update impacted our loan review services revenue, which is the only revenue stream in scope of the update. We adopted this update on January 1, 2018 using the modified-retrospective approach and the impact was immaterial to our consolidated financial statements.
In January 2016, the FASB issued ASU 2016-01, Financial Instruments - Overall: Recognition and Measurement of Financial Assets and Financial Liabilities (Subtopic 825-10). This update requires entities to reduce the carrying amount of deferred tax assets, if necessary, by the amount of any tax benefit that is not expected to be realized. We adopted this update effective January 1, 2018. The impact was immaterial to our consolidated financial statements.
In February 2018, the FASB issued ASU 2018-02, Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income (Topic 220). This update permits a company to reclassify the disproportionate income tax effects as a result of the 2017 Tax Cuts and Jobs Act (the TCJA) on items within accumulated other comprehensive income (AOCI) to retained earnings. This standard will take effect for public business entities for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2018. Early adoption is permitted. We adopted this update on January 1, 2018 and adjusted the disproportionate income tax effects, or "stranded tax effects," resulting in a $0.3 million reduction to our beginning retained earnings as of January 1, 2018.
Recent Accounting Pronouncements - Not Yet Adopted
In February 2016, the FASB issued ASU 2016-02,Leases (Topic 842). This update requires that businesses recognize rights and obligations associated with certain leases as assets and liabilities on the balance sheet. The standard also requires additional disclosures regarding the amount, timing, and uncertainty of cash flows arising from leases. For public business entities,We adopted this update is effective for annual periods beginning after December 15, 2018 and interim periods therein. Early adoption is permitted in any period. We expect to adopt this guidanceASU on January 1, 2019. In September 2017, ASU 2017-13 added guidance from a SEC Staff Announcement, "Transition Related to Accounting Standards Update No. 2016-02,"2019 using the modified-retrospective method and in July 2018, the FASB issued ASU 2018-11, Leases (Topic 842), Targeted Improvement, which provides companies the option to apply the provisions of the new lease standardapplied it prospectively as of the effective date, without adjusting comparative periods presented. The effectpresented as permitted by ASU 2018-11, Leases (Topic 842), Targeted Improvements. Adoption of adoption will depend onthis new standard increased our current lease portfolio at time of adoption; however, upon adoption, we anticipate that our reported assets and liabilities will increaseby $7.6 million in connection with the recognition of any right-of-use (ROU) assets and lease liabilities, such asprimarily related to the operating lease on our corporate headquarters. Adoption of this standard did not impact our consolidated statements of operations or cash flows. See Note 10,"Leases" for additional information related to our leases.

In July 2017, the FASB issued ASU 2017-11, Earnings Per Share (Topic 260), Distinguishing Liabilities from Equity (Topic 480), and Derivatives and Hedging (Topic 815). This update is intended to simplify the accounting for certain equity-linked financial instruments. We adopted this ASU on January 1, 2019. Adoption of this standard had no impact on our consolidated financial statements.
In June 2018, the FASB issued ASU 2018-07, Compensation-Stock Compensation (Topic 718). This update expands the scope of Topic 718 to include share-based payments made to non-employees in connection with the acquisition of goods and services. We adopted this ASU on January 1, 2019. Adoption of this standard had no impact on our financial results as we have not made any share-based grants to non-employees as defined in ASC 718-10-20.
Recent Accounting Pronouncements - Not Yet Adopted
In June 2016, the FASB issued ASU 2016-13, Financial Instruments-Credit Losses (Topic 326) and subsequently issued amendments to the initial guidance: ASU 2019-04, Codification Improvements to Topic 326, Financial Instruments-Credit Losses, (Topic 326)815, Derivatives and Hedging, and Topic 825, Financial Instruments, and ASU 2019-05, Financial Instruments – Credit Losses: Targeted Transition Relief. This update requiresThese updates will require companies to measure alland establish reserves for lifetime expected credit losses foron many financial assets held at thea given reporting date. The standard also amendsUnder the accountingguidance, the methodology for measuring lifetime credit losses will generally shift from an incurred loss model, whereby losses are only recognized once probable and estimable, to a current expected credit loss (CECL) model, whereby losses are recognized upfront based on a future economic forecast. Credit losses relating to available-for-sale fixed maturity securities will be recorded through an allowance for credit losses, on available-for-sale debt securities and purchased financial assetsrather than a write-down of the asset as is currently required, with the amount of the allowance limited to the amount by which fair value is less than amortized cost. The length of time an available-for sale fixed maturity security has been held in an unrealized loss position will no longer impact its credit deterioration.loss determination. The standard will take effect for public business entities for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2019. We are currently reviewing the impacts the adoptionThe impact of this guidance and the extent of the impact will have, if any,depend on, among other things, economic conditions and the composition and credit quality of our accounting for credit losses on our

While we are still evaluating the impact of this guidance, we do not expect it to have a material impact on our consolidated financial statements. This standard will not impact our accounting for insurance claims and claimsclaim expenses as these items are not in the scope of this ASU.
In July 2017, the FASB issued ASU 2017-11, Earnings Per Share (Topic 260), Distinguishing Liabilities from Equity (Topic 480), and Derivatives and Hedging (Topic 815). This update is intended to simplify the accounting for certain equity-linked financial instruments. The standard will take effect for public business entities for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2018. Early adoption is permitted. The guidance must be applied using a full or modified retrospective approach. We expect to adopt this ASU in the first quarter of 2019 and have determined that it will have no impact on our consolidated financial statements.
In June 2018, the FASB issued ASU 2018-07, Compensation-Stock Compensation (Topic 718). This update expands the scope of Topic 718 to include share-based payments made to non-employees in connection with the acquisition of goods and services. The standard will take effect for public business entities for fiscal years, beginning after December 15, 2019, and interim periods within fiscal years, beginning after December 15, 2020.

In August 2018, the FASB issued ASU 2018-12,Targeted Improvements to the Accounting for Long-Duration Contracts. This update provides guidance to the existing recognition, measurement, presentation and disclosure requirements for long-duration contracts issued by an insurance entity. The standard will take effect for public business entities for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2020. We are currently evaluating the impact the adoption of this ASU will have, if any, on our consolidated financial statements.

Aging of Unrealized Losses
As of September 30, 20182019, the investment portfolio had gross unrealized losses of $15.9 million, $7.8$0.7 million, of which has$0.4 million had been in an unrealized loss position for a period of 12 months or greater. We did not consider these securities to be other-than-temporarily impaired as of September 30, 2018.2019. We based our conclusion that these investments were not other-than-temporarily impaired as of September 30, 20182019 on the following facts: (i) the unrealized losses were primarily caused by interest rate movements and market fluctuations in credit spreads since the purchase date; (ii) we do not intend to sell these investments; and (iii) we do not believe that it is more likely than not that we will be required to sell these investments before recovery of our amortized cost basis, which may not occur until maturity. For those securities in an unrealized loss position, the length of time the securities were in such a position is as follows:

3. Fair Value of Financial Instruments
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
NMI HOLDINGS, INC.
NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED)

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.
Assets classified as Level 1 and Level 2
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.
Liabilities classified as Level 3
We calculate the fair value of outstanding warrants utilizing Level 3 inputs, including a Black-Scholes option-pricing model, in combination with a binomial model, and we value the pricing protection features within the warrants using a Monte-Carlo simulation model. Variables in the model include the risk-free rate of return, dividend yield, expected life and expected volatility of our stock price.

The respective outstanding reinsurance coverage amount willamounts stop amortizing if certain credit enhancement or delinquency thresholds, as defined in each agreement, are triggered.
Oaktown Re financed the coverage by issuing mortgage insurance-linked notes in an aggregate amount of $211.3 million to unaffiliated investors (the 2017 Notes). The 2017 Notes mature on April 26, 2027. All of the proceeds paid to Oaktown Re from the sale of the 2017 Notes were deposited into a reinsurance trust to collateralize and fund the obligations of Oaktown Re to NMIC under the reinsurance agreement. Funds in the reinsurance trust account are required to be invested in high credit quality money market funds at all times.  We refer collectively to NMIC's reinsurance agreement with Oaktown Re and the issuance of the 2017 Notes by Oaktown Re as the 2017 ILN Transaction. Under the terms of the 2017 ILN Transaction,
NMIC makes risk premium payments to the Oaktown Re Vehicles for the applicable outstanding reinsurance coverage amount and pays Oaktown Rean additional premium amount for anticipated operating expenses (capped at $300 thousand per year)year to Oaktown Re Ltd. and $250 thousand per year to Oaktown Re II, Ltd. and Oaktown Re III, Ltd.).

2018 ILN Transaction
In July 2018, NMIC entered into a reinsurance agreement with Oaktown Re II that provides for up to $264.5 million of aggregate excess-of-loss reinsurance coverage at inception for new delinquencies on an existing portfolio of mortgage insurance policies written between January 1, 2017 and May 31, 2018. For the reinsurance coverage period, NMIC retains the first layer of $125.3 million of aggregate losses, of which all remained at September 30, 2018, and Oaktown Re II then provides second layer coverage up to the outstanding reinsurance coverage amount. NMIC retains losses in excess of the outstanding reinsurance coverage amount. The outstanding reinsurance coverage amount decreases from $264.5 million at inception over a ten-year period as the underlying covered mortgages are amortized or repaid, and/or the mortgage insurance coverage is canceled, and was $264.5 million as of September 30, 2018. The outstanding reinsurance coverage amount will begin amortizing after an initial period in which a target level of credit enhancement is obtained and will stop amortizing if certain credit enhancement or delinquency thresholds are triggered.
Oaktown Re II financed the coverage by issuing mortgage insurance-linked notes in an aggregate amount of $264.5 million to unaffiliated investors (the 2018 Notes). The 2018 Notes mature on July 25, 2028. All of the proceeds paid to Oaktown Re II from the sale of the 2018 Notes were deposited into a reinsurance trust to collateralize and fund the obligations of Oaktown Re II to NMIC under the reinsurance agreement. Funds in the reinsurance trust account are required to be invested in high credit quality money market funds at all times. We refer collectively to NMIC's reinsurance agreement with Oaktown Re II and the issuance of the 2018 Notes by Oaktown Re II as the 2018 ILN Transaction, and the 2017 ILN Transaction and 2018 ILN Transaction as the ILN Transactions. Under the terms of the 2018 ILN Transaction, NMIC makes risk premium payments for the applicable outstanding reinsurance coverage amount and pays Oaktown Re II for anticipated operating expenses (capped at $250 thousand per year). For the three and nine months ended September 30, 2018, NMIC ceded risk premiums of $1.6 million. NMIC did not cede any losses to Oaktown Re II.
Under the reinsurance agreement, NMIC holds an optional termination right if certain events occur, including, among others, a clean-up call if the outstanding reinsurance coverage amount amortizes to 10% or less of the reinsurance coverage amount at inception or if NMIC reasonably determines that changes to GSE or rating agency asset requirements would cause a material and adverse effect on the capital treatment afforded to NMIC under the agreement. In addition, there are certain events that will result in mandatory termination of the agreement, including NMIC's failure to pay premiums or consent to reductions in the trust account to make principal payments to noteholders, among others.
Under the terms of the 2018 ILN Transaction and the 2019 ILN Transaction, we are required to maintain a certain level of restricted funds in a premium deposit accountaccounts with Bank of New York Mellon until the 2018 Notesrespective notes have been redeemed in full. "Cash and cash equivalents" on our condensed consolidated balance sheet includes restricted cashamounts of $1.4$2.9 million as of September 30, 2018.2019. We are not required to deposit additional funds into the premium deposit accountaccounts in the future and the restricted balancebalances will decrease over time as the outstanding principal balancebalances of the respective insurance-linked notes decline.
The amount of reinsurance premiums ceded under each ILN Transaction fluctuates based on changes in one-month LIBOR and changes in the earned rate on the money market funds in which the assets of the reinsurance trusts are invested. As the reinsurance premiums will vary based on changes in these rates, we have concluded that the ILN Transactions each contain an embedded derivative that must be treated separately as a freestanding derivative.  The total fair value of such derivatives at September 30, 2019 and December 31, 2018, Notes declines.and the change in fair value of the derivatives during the three and nine months ended September 30, 2019 and 2018, were not material to our condensed consolidated financial statements.

NMIC may terminate either or both 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.

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED)

Effective April 1, 2019, NMIC elected to terminate its engagement with one reinsurer under the 2016 QSR Transaction on a cut-off basis. In connection with the termination, NMIC recaptured approximately $500 million of previously ceded primary RIF and stopped ceding new premiums earned or written with respect to the recaptured risk.  With the termination, ceded premiums written under the 2016 QSR Transaction decreased from 25% to 20.5% on eligible policies.  The termination has no effect on the cession of pool risk under the 2016 QSR Transaction.

Ceded premiums written under the 2016 QSR Transaction are recorded on the balance sheet as prepaid reinsurance premiums and amortized to ceded premiums earned in a manner consistent with the recognition of revenue on direct premiums. Under the 2018 QSR Transaction, 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. NMIC also receives a profit commission under each of the QSR Transactions, provided that the loss ratioratios on the loans covered under the 2016 QSR Transaction and 2018 QSR Transaction generally remainsremain below 60% and 61%, respectively, as measured annually. Ceded claims and claim expenses under each of the QSR Transactions reduce NMIC'sthe 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 will be 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 our 2016 QSR Transaction was $2.5$2.6 million as of September 30, 2018.2019.
In accordance with the terms of the 2018 QSR Transaction, 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 settled 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 reinsurance recoverable on loss reserves related to our 2018 QSR Transaction was $64 thousand$1.7 million as of September 30, 2018.2019.
6. Reserves for Insurance Claims and Claim Expenses
We establish reserves to recognize the estimated liability for insurance claims and claim expenses related to defaults on insured mortgage loans. Consistent with industry practice, we establish reserves for loans that have been reported to us by servicers as having been in default for at least 60 days, referred to as case reserves, and additional loans that we estimate (based on actuarial review) have been in default for at least 60 days that have not yet been reported to us by servicers, referred to as incurred but not reported (IBNR) reserves. We also establish claimsclaim expense reserves, which represent the estimated cost of the claim administration process, including legal and other fees, as well as other general expenses of administering the claims settlement process. As of September 30, 2018,2019, we had reserves for insurance claims and claimsclaim expenses of $10.9$20.5 million for 7461,230 primary loans in default. During the first nine months of 2018,ended September 30, 2019, we paid 5998 claims totaling $2.2$3.0 million, including 4291 claims covered under the QSR Transactions representing $438 thousand$0.6 million of ceded claims and claimsclaim expenses.
In 2013, we entered into a pool insurance transaction with Fannie Mae. The pool transaction includes a deductible, which represents the amount of claims to be absorbed by Fannie Mae before we are obligated to pay any claims. We only establish reserves for pool risk if we expect claims to exceed this deductible. At September 30, 2018, 532019, 49 loans in the pool were past due by 60 days or

8. Warrants
We issued 992 thousand warrants in connection with the Private Placement.a private placement of our common stock in April 2012. Each warrant gives the holder thereof the right to purchase one1 share of common stock at an exercise price equal to $10.00. The warrants were issued with an aggregate fair value of $5.1 million.
During the three months ended September 30, 2019, 130 thousand warrants were exercised resulting in the issuance of 82 thousand shares of common stock. Upon exercise, we reclassified approximately $2.2 million of warrant fair value from warrant liability to additional paid-in capital, of which $0.9 million related to changes in fair value during the three months ended September 30, 2019. During the nine months ended September 30, 2019, 390 thousand warrants were exercised resulting in the issuance of 249 thousand shares of common stock. Upon exercise, we reclassified approximately $7.0 million of warrant fair value from warrant liability to additional paid-in capital, of which $3.2 million related to changes in fair value during the nine months ended September 30, 2019.
During the three months ended September 30, 2018, 79 thousand warrants were exercised resulting in the issuance of 57 thousand shares of common stock. Upon exercise, we reclassified approximately $0.9 million of warrant fair value from warrant liability to additional paid-in capital, of which $0.3 million related to changes in fair value during the three months ended September 30, 2018. During the nine months ended September 30, 2018, 142 thousand warrants were exercised resulting in the issuance of 87 thousand shares of common shares issued. No warrants were exercisedstock. Upon exercise, we reclassified approximately $1.5 million of warrant fair value from warrant liability to additional paid-in capital, of which $0.3 million related to changes in fair value during the nine months ended September 30, 2017. Upon exercise, we reclassified the fair value of the warrants from warrant liability to additional paid-in capital and recognized a loss of approximately $333 thousand.2018.
We account for these warrants to purchase our common shares in accordance with ASC 470-20, Debt with Conversion and Other Options and ASC 815-40, Derivatives and Hedging - Contracts in Entity's Own Equity.
9. Income Taxes
We are a U.S. taxpayer and are subject to a statutory U.S. federal corporate income tax rate of 21% for the current and all future years following the enactment of the TCJA on December 22, 2017. We were subject to a statutory U.S. federal corporate income tax rate of 35% for all prior years through December 31, 2017.. NMIH files a consolidated U.S. federal and various state income tax returns on behalf of itself and its subsidiaries. Our effective tax rate on our pre-tax income was 22.2% and 20.9% for the three and nine months ended September 30, 2019, respectively, compared to 22.1% and 20.2% for the three and nine months ended September 30, 2018, respectively. Our provision for income taxes for interim reporting periods is established based on our estimated annual effective tax ratesrate for a given year. Our effective tax rate on our pre-tax income was 22.1% and 20.2% for the three and nine months ended September 30, 2018, respectively, compared to 36.9% and 33.3% for the three and nine months ended September 30, 2017, respectively. The decrease in the effective tax rates for the three and nine months ended September 30, 2018 compared to the three and nine months ended September 30, 2017 is attributable to the decrease in the statutory U.S. federal corporate income tax rate. We currently pay no federal income tax primarilymay fluctuate between interim periods due to the forecasted utilizationimpact of discrete items not included in our federal net operating loss carryforwards, which were $93.9 million as of December 31, 2017. As a result, the interim provision for income taxes represents changes to deferred tax assets.
Provisional amounts
The TCJA reduced the statutory U.S. federal corporate incomeestimated annual effective tax rate, from 35% to 21% and changed the tax deductibility of certain expenses for tax years beginning after December 31, 2017. We have not completed our full assessment ofincluding the tax effects associated with the vesting of RSUs and exercise of options, and the enactmentchange in fair value of our warrant liability.

We recognized a $13.6 million income tax expense in the year ended December 31, 2017 for the items we could reasonably estimate. We are still analyzing the TCJA and refining our calculations, which could impact the measurement of our existing deferred tax assets including those related to share-based compensation. For tax years beginning after December 31, 2017, the TCJA expanded the number of individuals whose compensation isstatutory contingency reserve balance, subject to a $1 million cap oncertain limitations outlined under IRC Section 832(e), and only to the extent we acquire tax deductibility and includes performance-based compensationloss bonds in an amount equal to the calculation.tax benefit derived from the claimed deduction, which is our intent. As a result, our interim provision for income taxes for the three and nine months ended September 30, 2019 represents a change in our net deferred tax liability. During the three and nine months ended September 30, 2019, we recorded a provisional amount to reduce the futurehad net purchases of $7.6 million of tax benefit related to share-based compensation. We will continue to make and refine our calculations as additional analysis is completed. In addition, our estimates may also be affected as we incorporate additional guidance that may be issued by the U.S. Treasury Department, the IRS, or other standard-setting bodies.
In February 2018, the FASB issued ASU 2018-02, Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income (Topic 220). This update permits a company to reclassify the disproportionate income tax effects as a result of the TCJA on items within AOCI to retained earnings. We adopted this update on January 1, 2018loss bonds, and, adjusted the disproportionate income tax effects, or "stranded tax effects," resulting in a $0.3 million reduction to our beginning retained earnings as of January 1, 2018.

Item 2. Management's Discussion and Analysis of Financial Condition and Results of Operations
The following analysis should be read in conjunction with our unaudited condensed consolidated financial statements and the notes thereto included in this report and our audited financial statements, notes thereto and "Management's Discussion and Analysis of Financial Condition and Results of Operations" included in our 20172018 10-K, for a more complete understanding of our financial position and results of operations. In addition, investors should review the "Cautionary Note Regarding Forward-Looking Statements" above and the "Risk Factors" detailed in Part II, Item 1A of this report and in Part I, Item 1A of our 20172018 10-K, and Part II, Item 1A of our First Quarter 10-Q, as subsequently updated in other reports we file with the SEC, for a 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. Our results of operations for interim periods are not necessarily indicative of results to be expected for a full fiscal year or for any other period.
Overview
We provide private MI through our wholly owned insurance subsidiaries NMIC and Re One. NMIC and Re One are domiciled in Wisconsin and principally regulated by the Wisconsin OCI. NMIC is our primary insurance subsidiary and is approved as an MI provider by the GSEs and is licensed to write coverage in all 50 states and D.C. Re One provides statutorily required reinsurance to NMIC on insured loans with coverage levels in excess of 25% after giving effect to third-party reinsurance. Our subsidiary, NMIS, provides outsourced loan review services to mortgage loan originators.
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-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 September 30, 2018,2019, we had master policy relationshipspolicies with 1,3401,450 customers, including national and regional mortgage banks, money center banks, credit unions, community banks, builder-owned mortgage lenders, internet-sourced lenders and other non banknon-bank lenders. As of September 30, 2018,2019, we had $66.5$92.4 billion of total insurance-in-force (IIF), including primary IIF of $63.5$89.7 billion, and $15.8$22.9 billion of gross RIF, including primary RIF of $15.7$22.8 billion.
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 the dream oftheir homeownership goals, ensure that we remain a strong and credible counter-party, deliver a unique 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 GPSSM 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. As of September 30, 2018, we had 300 full-time employees.
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 claimsclaim payment practices, responsive customer service, financial strength and profitability.
Our common stock trades on the NASDAQ under the symbol "NMIH." Our headquarters is located in Emeryville, California. As of September 30, 2019, we had 318 full time employees.

New Insurance Written, Insurance In ForceInsurance-In-Force and Risk In ForceRisk-In-Force
New insurance written (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, which tend to be generated to a greater extent in purchase originations as compared to refinancings.originations. Our NIW is also affected by the percentage of such high-LTV originations covered by private versus publicgovernment 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.
Net Premiums Written and Net Premiums Earned
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. EffectiveOn June 4, 2018, we implemented ourintroduced a proprietary risk-based pricing platform, which we refer to as Rate GPSSM. Rate GPS considers upa 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 30 individualset and charge premium rates commensurate with the underlying risk variables to assist in our underwriting selection process and determine policy pricing on an individualof each loan basis.that we insure. We introduced Rate GPS evaluates a broader and more granular spectrum of risk attributes thanin June 2018 to replace our previous rate card pricing system and, we believe, provides us with an increased ability to alignsystem. While most of our premium rates with the risks of each individual loan. Although we expect most new business to beis priced through Rate GPS, we willalso 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 will enhanceprovides 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 allow us to achievedelivering attractive risk-adjusted returns in line with our pricing expectations.returns.
Premiums are generally fixed overfor the estimated lifeduration of our coverage of the underlying loans. Net premiums written are equal to gross premiums written minus ceded premiums written under our reinsurance arrangements, and less premium refunds. 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 claimsclaim payments and home prices; and
cession of premiums under third-party reinsurance arrangements.
Premiums are paid either by the borrower (BPMI) or the lender (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 initially recorded as unearned premium and earned over the estimated life of the policy. A majoritySubstantially all of our single premium policies in force as of September 30, 20182019 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 12-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 substantially all of 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 or greater premium rate or higher, our profitabilityrevenue is likely to decline.
Effect of reinsurance on our results
We utilize third-party reinsurance to actively manage our risk, ensure compliance with PMIERs, compliancestate 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 net premiums written and earned and also reduces net 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. In general, there are no ceding commissions under excess-of-loss reinsurance agreements. We expect to continue to evaluate reinsurance opportunities in the normal course of business.

Under the terms of the 2016 QSR Transaction, NMIC cedes premiums written related to 25% 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, 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.
Effective January 1, 2018, NMIC entered into the 2018 QSR Transaction with a syndicate of third-party reinsurers. Under the 2018 QSR Transaction, NMIC has ceded or will cedecedes premiums earned related to 25% of itsthe risk on eligible policies written in 2018 and 20% to 30% (such amount to be determined by NMIC at its sole election by December 1, 2018) of the risk on eligible policies written in 2019, in exchange for reimbursement of ceded claims and claimsclaim expenses on covered policies, a 20% ceding commission, and a profit commission of up to 61% that varies directly and inversely with ceded claims.
NMIC entered into the 2016 QSR Transaction in September 2016. 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.

Effective April 1, 2019, NMIC elected to terminate its engagement with one reinsurer under the 2016 QSR Transaction on a cut-off basis. In connection with the termination, NMIC (1)recaptured approximately $500 million of previously ceded 100% ofprimary RIF and stopped ceding new premiums written with respect to the risk relatingrecaptured risk. With this termination, ceded premiums written under the 2016 QSR Transaction decreased from 25% to our pool agreement with Fannie Mae, (2) ceded 25% of existing risk written20.5% on eligible policies aspolicies. The termination had no effect on the cession of August 31,pool risk under the 2016 and (3) ceded 25% of the risk relating to eligible primary insurance policies written between September 1, 2016 and December 31, 2017, in exchange for reimbursement of ceded claims and claims expenses on covered policies, a 20% ceding commission, and a profit commission of up to 60% that varies directly and inversely with ceded claims.QSR Transaction.

NMIC then retains losses in excess of the 2018 ILN Transaction decreasesrespective reinsurance coverage amounts.

NMIC applies claims paid on covered policies against its first layer aggregate retained loss exposure under each excess-of-loss agreement. The respective reinsurance coverage amounts provided by the Oaktown Re Vehicles decrease from $264.5 million atthe inception of each agreement over a ten-year period as the underlying coveredinsured mortgages are amortized or repaid, and/or the mortgage insurance coverage is canceled.

In May 2017, NMIC secured $211.3 million of aggregate excess-of-loss reinsurance coverage at inception for an existing portfolio of MI policies written from 2013 through December 31, 2016, through a mortgage insurance-linked notes offering by Oaktown Re. The reinsurance coverage amount under the terms of the 2017 ILN Transaction decreases from $211.3 million at inception over a ten-year period as the underlying covered mortgages are amortized or repaid, and/or the mortgage insurance coverage is canceled and was $144.1 million as of September 30, 2018. For the reinsurance coverage period, NMIC retains the first layer of $126.8 million of aggregate losses, of which $125.6 million remained as of September 30, 2018, and Oaktown Re then provides second layer of coverage up to the outstanding reinsurance coverage amount. NMIC retains losses in excess of the outstanding reinsurance coverage amount.

The increases in net premiums written and earned are due to the growth of our IIF and increased monthly policy production, partially offset by increased cessions under the QSR Transactions tied to the growth of our direct premium volume and the inception dates of the 2018 and 2019 ILN Transactions. The growth of our net premiums written andSingle premium policy cancellations also contributed to the increases in net premiums earned was also impacted by the QSR Transactions. Under the 2016 QSR Transaction, premiums on singles policies are ceded on a written basis, with unearned premium reserves ceded and recognized on balance sheet as prepaid reinsurance premiums, and subsequently amortized to earnings in a manner consistent with the recognition of earnings on direct premiums written. Under the 2018 QSR Transaction, premiums on singles policies are ceded on an earned basis. The reinsurance coverage period for the 2016 QSR Transaction ended for new policies written after December 31, 2017,three and we did not cede any unearned premium reserves on singles policies under the 2016 QSR Transaction during the three or nine months ended September 30, 2018. We did, however, continue to recognize earnings from the amortization of prepaid reinsurance premiums on policies previously ceded under the 2016 QSR Transaction. This contributed to accelerated growth in net premiums earned2019 compared to net premiums written for the same periods presented.in 2018.

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.

We utilize certain risk principles that form the basis of how we underwrite and originate primary NIW. We manage our portfolio credit risk by using several loanhave established prudential underwriting standards and loan-level eligibility matrices which prescribe the maximum LTV, minimum borrower creditFICO score, maximum borrower debt-to-income (DTI) ratio, maximum loan size, property type, loan type, loan term and occupancy status of loans that we will insure. Our loaninsure and memorialized these standards and eligibility matrices as well as all of our detailed underwriting guidelines, are contained in our Underwriting Guideline Manual that is publicly available on our website. Our underwriting standards and eligibility criteria and underwriting guidelines are designed to mitigatelimit the layeredlayering of risk inherent in a single insurance policy. "Layered risk" refers to the accumulation of borrower, loan and property risk. For example, we have higher credit score and lower maximum allowed LTV requirements for investor-owned properties, compared to owner-occupied properties. We monitor the concentrations of various risk attributes in our insurance portfolio, which may change over time, in part, as a result of regional conditions or public policy shifts.
The tables below present our primary NIW by FICO, LTV and purchase/refinance mix for the periods indicated. We calculate the LTV of a loan as the percentage of the original loan amount to the original purchase value of the property securing the loan.

Geographic Dispersion
The following table shows the distribution by state of our primary RIF as of the periods indicated. As of September 30, 2018,2019, our RIF continues to be relatively more concentrated in California, primarily as a result of the size of the California mortgage market relative to the rest of the country and the location and timing of our acquisition of new customers. The distribution of riskour primary RIF as of September 30, 20182019 is not necessarily representative of the geographic distribution we expect in the future.

Insurance Claims and Claim Expenses
Insurance claims and claim expenses incurred represent estimated future payments on newly defaulted insured loans and any change in our claim estimates for previously existing defaults. Claims incurred is generally affected by a variety of factors, including the state of the economy,macroeconomic environment, national and regional unemployment trends, changes in housing values, loanborrower risk characteristics, LTV ratios and borrowerother loan level risk characteristics,attributes, the size and type of loans insured, and the percentage of coverage on insured loans.
Reserves for claims and allocated claim expenses are established for reported mortgage loan defaults, which we refer to as case reserves, when we are notified that a borrower has missed two or more mortgage payments (i.e., an NOD). We also make estimates of IBNR defaults, which are defaults that have been incurred but have not been reported by loan servicers, based on historical reporting trends, and establish IBNR reserves for those estimates.defaults. We also establish reserves for unallocated claimsclaim expenses not associated with a specific claim. The claimsClaim expenses consist of the estimated cost of the claim administration process, including legal and other fees as well as other general expenses of administering the claimsclaim settlement process.
Reserves are established by estimating the number of loans in default that will result in a claim payment, which is referred to as claim frequency, and the amount of the claim payment expected to be paid on each such loan in default, which is referred to as claim severity. Claim frequency and severity estimates are established based on historical observed experience regarding certain loan factors, such as age of the default, cure rates, size of the loan and estimated change in property valuation.value. Reserves are released the month in which a loan in default is brought current by the borrower, which is referred to as a cure. Adjustments to reserve estimates are reflected in the period in which the adjustment is made. Reserves are also ceded to reinsurers under the QSR Transactions. We will not cede reserves to reinsurersclaims under the ILN Transactions unless losses exceed the respective retained coverage layers. Reserves are not established for future claims on insured loans which are not currently in default.
Based on our experience and industry data, we believe that claims incidence for mortgage insurance is generally highest in the third through sixth years after loan origination. Although the claims experience on new primary insurance written by us to date has been favorable, we expect incurred claims to increase as a greater amount of our existing insured portfolio reaches its anticipated period of highest claim frequency. We estimate that the loss ratio over the life of our existing primary insured portfolio will be between 20% and 25% of earned premiums, and we price to that expectation. Additionally, our Our pool insurance agreement with Fannie Mae contains a claim deductible through which Fannie Mae absorbs specified losses before we are obligated to pay any claims. We have not established any poolclaims or claim expense reserves for claims or IBNRpool exposure to date.
Based on our experience and industry data, we believe that claims incidence for mortgage insurance is generally highest in the third through sixth years after loan origination. As of September 30, 2019, approximately 82% of our primary IIF related to business written since September 30, 2016. Although the claims experience on our IIF to date has been modest, we expect incurred claims to increase as a greater amount of our existing insured portfolio reaches its anticipated period of highest claim frequency.
The actual claims we incur as our portfolio matures are difficult to predict and depend on the specific characteristics of our current in-force book (including the credit score and DTI of the borrower, the LTV ratio of the mortgage and geographic concentrations, among others), as well as the risk profile of new business we write in the future. In addition, claims experience will be affected by future macroeconomic factors such as housing prices, interest rates, and employmentunemployment rates and other events, such as natural disasters. To date, our claims experience is developing at a slower pace than historical trends indicate, as a result of high quality underwriting,


a strong


macroeconomic environment and a favorable housing market. For additional discussion of our reserves, see Item 1, "Financial Statements - Notes to Condensed Consolidated Financial Statements - Note 6, Reserves for Insurance Claims and ClaimsClaim Expenses."
We insure mortgages for homes in areas that have beenare impacted by recent natural disasters. We do not provide coverage for property or casualty claims related to physical damage of a home underpinning an insured mortgage. We experienced an increase in NODs on insured loans in areas impacted by such disasters in the fourth quarter of 2017 and the first quarter of 2018. In the second and third quarters of 2018, we experienced an increase in cure activity on this NOD population. Our ultimate claims exposure for loans in areas impacted by natural catastrophesdisasters will depend on the number of NODs received, proximate cause of each default, cure rate of the NOD population, and potential repair cost curtailment for appropriate claims on damaged properties as permitted byunder our Master Policy. In the event ofCure rates on loan defaults following natural disasters cure rates are influenced by the adequacy of homeowners and other hazard insurance carried on a related property, GSE-sponsored forbearance and other assistance programs, and a borrower's access to aid from government entities and private organizations, in additionaddition to other factors which generally impact cure rates in unaffected areas.

The "claims incurred" section of the table above shows claims and claim expenses incurred on NODs for current and prior years, including IBNR reserves and is presented net of reinsurance. The amount of claims incurred for current year NODs represents the estimated amount to be ultimately paid on such loans in default. The decreases during the periods presented in reserves held for prior year defaults represent favorable development and are generally the result of NOD cures and ongoing analysis of recent loss development trends. We may increase or decrease our original estimates as we learngather additional information about individual defaults


and claims and continue to observe and analyze loss development trends in our portfolio. Gross reserves of $3.7$6.6 million related to prior year defaults remained as of September 30, 2018.2019.

The increase in the ending default inventory at September 30, 20182019 compared to September 30, 2017 was2018, primarily duerelates to the aging of earlier book years and an increase in new defaults tied to the overallgrowth in the number of policies in force and the aging of our portfolio which, historically drives a general increaseearlier book years, partially offset by cure activity on our beginning NOD population. The ratio of cures to new defaults decreased during the three and nine months ended September 30, 2019 compared to the same periods in defaults, as well asthe prior year due to the elevated level of defaults on insured loans in areas impacteddeclared by natural disasters that occurredFEMA to be individual disaster zones following Hurricanes Harvey and Irma, and the California wildfires in late 2017.2017, and the subsequent curing of the majority of such defaults in 2018.

(3)     Severity represents the total amount of claims paid including claims expenses divided by the related RIF on the loan at the time the claim is perfected.
The increase in the number of claims paid for the three and nine months ended September 30, 2018,2019, compared to the same periodsthree and nine months ended September 30, 2017,2018, is due to an increase in our default inventory and the continued growth and seasoning of our insured portfolio.
Our claims severity for each of the three and nine months ended September 30, 2019 was 70%, compared to 80% and 76% for the three and nine months ended September 30, 2018. Claims settled without payment are includedseverity in claim counts, but excludedeach period benefitted from averages.home price appreciation. Increasing values of the homes underlying the loans we insure generally causes a decline in the severity of claims that we pay. Over time, we expect the severity of claims paid to be between 85% and 95% of the coverage amount. We believe our severity for the period ended September 30, 2018 is below long-term expectations due to home price appreciation in recent periods.

The average reserve per default at September 30, 2018 decreased2019 increased from September 30, 2017,2018, primarily due to cure activity on defaults on insuredoutstanding at September 30, 2018 for loans in areas impacted by natural disasters. Asdisasters and the aging of September 30, 2018, 91 of the 746 loans in default relate to homes in areas declared by FEMA to be disaster zones following natural catastrophes.  We expect that this population of loans in default will cure at a higher rate than the estimated rate we apply to non-disaster related loans in default, due to our historical and observed industry


experience, and current economic indicators and relief programs. As such, we have established lower reserves for this population of NODs than we otherwise would for a similarly situated set of NODs in non-disaster zones. Over time, we anticipate that our average reserve per default will increase as the NODs in these zones cure and our NOD population continues to age.from non-disaster zones.
GSE Oversight
As anApproved Insurer approved insurer, NMIC is subject to ongoing compliance with the PMIERs.PMIERs established by each of the GSEs (Italicizeditalicized terms have the same meaning that such terms have in the PMIERs, as described below.)below). The PMIERs establish operational, business, remedial and financial requirements applicable toApproved Insurers approved insurers. The PMIERs financial requirements prescribe a risk-based methodology whereby the amount of assets required to be held against each insured loan is determined based on certain loan-level risk characteristics, such as FICO, vintage (year of origination), performing vs. non-performing (i.e., current vs. delinquent), LTV ratio and other risk features. An asset charge is calculated for each insured loan based on its risk profile. In general, higher quality loans carry lower asset charges.
Under the PMIERs, financial requirements, Approved Insurers approved insurers must maintainavailable assets that equal or exceedminimum required assets, which is an amount equal to the greater of (i) $400 million or (ii) a total risk-based required asset amount. Therisk-based required asset amount is a function of the risk profile of anApproved Insurer's net approved insurer's RIF, calculated by applyingassessed on a loan-by-loan basis and considered against certain risk-based factors derived from tables set out in the PMIERs to the net RIF, and other transactional adjustments, which is then adjusted on an aggregate basis for reinsurance transactions approved by the GSEs, such as with respect to our ILN Transactions and QSR Transactions. Therisk-based required asset amountfor performing, primary insurance is subject to a floor of 5.6% of total, performing primary adjusted RIF, and the risk-based required asset amountfor pool insurance considers both the factors in the PMIERs tables and thenet remaining stop lossfor each pool insurance policy. The PMIERs financial requirements also increase the amount of available assets that must be held by an Approved Insurer for LPMI policies originated on or after January 1, 2016.
By April 15th of each year, NMIC must certify it met all PMIERs requirements as of December 31st of the prior year. We certified to the GSEs by April 15, 20182019 that NMIC was in full compliance with the PMIERs as of December 31, 2017.2018. NMIC also has an ongoing obligation to immediately notify the GSEs in writing upon discovery of a material failure to meet one or more of the PMIERs requirements. We continuously monitor ourNMIC's compliance with the PMIERs.
The following table provides a comparison of the PMIERs financial requirements as reported by NMIC as of the dates indicated.

Risk-based required assets398,975
356,207
The increase in available assets of $207 million as of September 30, 2018 compared to September 30, 2017 is driven by our positive cash flow from operations and a $70 million capital contribution from NMIH to NMIC during the second quarter of 2018, partially offset by an increase in our unearned premium reserve. The increase in the risk-based required asset amount of $43 million is due to the growth of our gross RIF and, to a lesser extent, an increase in our NOD population, which has a higher risk-based required asset amount charge, partially offset by the cession of risk relating to our third-party reinsurance agreements.
On September 27, 2018, the GSEs published revised PMIERs that will taketook effect and becomebecame applicable to NMIC on March 31, 2019. We expect thatThe following table provides a comparison of the PMIERs available assets and risk-based required asset amount as reported by NMIC will remainas of the dates indicated as calculated under the applicable PMIERs requirement.

Available assets were $956 million at September 30, 2019, compared to $702 million at September 30, 2018. The increase in full compliance withavailable assets of $254 million was driven by our positive cash flow from operations and the existing andimpact of adopting the revised PMIERs as applicable, prior to and afterguidance effective March 31, 2019. The increase in the risk-based required asset amount was primarily due to the growth of our gross RIF and the termination of our engagement with and recapture of previously ceded primary RIF from one reinsurer under the 2016 QSR Transaction, partially offset by the cession of risk generally under our third-party reinsurance agreements.


Capital Position of Our Insurance Subsidiaries and Financial Strength Ratings
In addition to GSE-imposed asset requirements, NMIC is also subject to state regulatory minimum capital requirements based on its RIF. While formulations of this minimum capital may vary by jurisdiction, the most common measure allows for a maximum permitted RTC ratio of 25:1.
As of September 30, 2018,2019, NMIC's performing primary RIF, net of reinsurance, was approximately $9.7$13.2 billion. NMIC ceded 100% of its pool RIF pursuant to the 2016 QSR Transaction. Based on NMIC's total statutory surpluscapital of $698.0$888 million (including contingency reserves) as of September 30, 2018,2019, NMIC's RTC ratio was 13.9:14.8:1. Re One had total statutory capital of $34.7$36 million as of September 30, 2018, with2019, and a RTC ratio of 1.0:1.2:1. We continuously monitor our compliance with state capital requirements.


In May 2018,October 2019, Moody's Investors Service (Moody's) upgraded its financial strength rating of NMIC from "Ba1""Baa3" to "Baa3" for NMIC"Baa2" and issued a "Ba3"upgraded its rating forof NMIH's $150 million senior secured 2018 Term Loan comparedand 2018 Revolving Credit Facility from "Ba3" to its previous "B1" rating on the 2015 Term Loan."Ba2". The outlook for bothMoody's ratings is stable. In July 2018,June 2019, S&P affirmedupgraded its "BBB-" financial strength and long-term counter-party credit ratings onof NMIC from "BBB-" to "BBB" and upgraded its "BB-" long-term counter-party credit rating on NMIH.of NMIH from "BB-" to "BB". The outlook on bothfor S&P's ratings is positive.
Competition
The MI industry is highly competitive and currently consists of six private mortgage insurers, including NMIC, as well as publicgovernment MIs likesuch as the FHA, and theUSDA or VA. Private MI companies compete based on service, customer relationships, underwriting and other factors, including price.price, credit risk tolerance and information technology capabilities. We expect the private MI market to remain competitive, with pressure for industry participants to growmaintain or maintaingrow their market share.
The private MI industry overall competes more broadly with publicgovernment MIs who significantly increased their presence in the MI market following the financial crisis. Although there has been broad policy consensus toward the need for increasing private capital to play a larger roleparticipation and decreasing government exposure to credit risk to be reduced in the U.S. housing finance system, it remains difficult to predict whether the combined market share of publicgovernment MIs will recede to historical levels. A range of factors influence a lender's and borrower's decision to choose private over publicgovernment MI, including among others, premium rates and other charges, loan eligibility requirements, cancelability, loan size limits and the relative ease of use of private MI products compared to publicgovernment MI alternatives.

Revenues
For the three and nine months ended September 30, 2018,2019, net premiums earned increased $20.9$27.0 million or 47%41% and $66.3$67.6 million or 57%37%, respectively, compared to the three and nine months ended September 30, 2017.2018. The increase in both periods is primarily due to the growth of our IIF and increased monthly policy production, as well as an increase in earnings from single premium policy cancellations, partially offset by increases toincreased cessions under the QSR Transactions tied to the growth of our direct premium volume and the inception dates of the 2018 and 2019 ILN Transactions.
For the three and nine months ended September 30, 2018,2019, net investment income increased $2.1$1.6 million and $4.7$6.3 million, respectively, compared to the three and nine months ended September 30, 20172018, due to an increase in the size and yield of and improved yields on our total investment portfolio.
For the three and nine months ended September 30, 2019, other revenues increased $1.2 million and $1.5 million, respectively, compared to the three and nine months ended September 30, 2018. Other revenues represents underwriting fee revenue from our subsidiary, NMIS, which provides outsourced loan review services to mortgage loan originators. The increase in the period presented is due to an increase in NMIS' outsourced loan review volume. Amounts recognized in other revenue generally correspond with amounts incurred in underwriting and operating expenses for outsourced loan review services (in the same periods).



Expenses
We recognize insurance claims and claim expenses in connection with the loss experience of our insured portfolio and incur other underwriting and operating expenses, including employee compensation and benefits, policy acquisition costs, and technology, professional services and facilities expenses, in connection with the development and operation of our business.
Insurance claims and claim expenses increased $0.1$1.5 million or 15% and $0.3$4.9 million or 12% for the three months and nine months ended September 30, 2018, respectively, compared to the three months and nine months ended September 30, 2017, primarily due to an increase in new NODs and aging of existing NODs, partially offset by the release of reserves related to prior year defaults.


Underwriting and operating expenses increased $5.7 million or 23% and $9.2 million or 12%, for the three and nine months ended September 30, 2018,2019, respectively, compared to the three and nine months ended September 30, 2017. Employee compensation accounts2018, primarily due to an increase in NODs tied to the growth in the number of policies in force and the aging of our earlier book years, and an increase in our average reserve per default tied to the aging of our NOD population from non-disaster zones and composition of our default inventory between loans in disaster and non-disaster impacted areas. The growth in insurance claims and claim expenses for the majoritythree and nine months ended September 30, 2018 was partially offset by the release of ourprior year reserves tied to NOD cures and ongoing analysis of recent loss development trends.
Underwriting and operating expenses which increased $2.9 million or 9% and $8.8 million or 10% for the three and nine months ended September 30, 2019, respectively, compared to the three and nine months ended September 30, 2018. The increase relates to an increase in underwriting expenses associated with the growth in our policy volume, as well as certain employee compensation and technology costs incurred to support the growth of our business, particularlyand an increase in our operating functions.NMIS’ outsourced loan review expenses incurred in connection with the growth in outsourced loan review volume. We incurred $2.6$2.4 million of underwriting and operating expenses during the nine months ended September 30, 20182019 in connection with the 20182019 ILN Transaction completed in July 2018.2019. Underwriting and operating expenses for the nine months ended September 30, 20172018 included $4.8$2.6 million related to the 20172018 ILN Transaction and an amendment of the 2015 Credit Agreement.completed in July 2018.
Interest expense was $3.0 million and $9.1 million for the three and nine months ended September 30, 2019, respectively, compared to $3.0 million and $12.0 million, for the three and nine months ended September 30, 2018, respectively, compared to $3.4 million and $10.1 million, respectively, for the three and nine months ended September 30, 2017.respectively. Interest expense for the nine months ended September 30, 2018 included $2.2 million of costs related to the extinguishment of the 2015 Term Loan and issuance of the 2018 Term Loan completed in May 2018. Interest expense for the threenine months ended September 30, 2018 declined compared to the three months ended September 30, 2017 due to the reduction in the2019 further benefited from a lower interest spread payable on our borrowings under the 2018 Term Loan as compared to the 2015 Term Loan.Loan, partially offset by commitment fees recognized in interest for the 2018 Revolving Credit Facility. See Item 1, "Financial Statements - Notes to Condensed Consolidated Financial Statements - Note 4, Debt Obligations.Debt."
Income tax expense increasedwas $14.2 million and $32.1 million for the three and nine months ended September 30, 2019, respectively, compared to $7.0 million and $18.3 million for the three and nine months ended September 30, 2018, from $11.9 million for the nine months ended September 30, 2017 because ofrespectively. Income tax expense increased due to the growth in our pre-tax income, partially offset by a decrease in our effective tax rate. Our effective tax rate on our pre-tax income decreased to 20.2% for the nine months ended September 30, 2018 from 33.3% for the nine months ended September 30, 2017, primarily because the TCJA reduced the statutory U.S. federal corporate income tax rate to 21% for the current and all future years from 35% for all prior years through December 31, 2017.income. Our provision for income taxes for interim periods is established based on our estimated annual effective tax rate for a given year. We expect our annualOur effective tax rate on our pre-tax income was 22.2% and 20.9% for the year ending December 31,three and nine months ended September 30, 2019, respectively, compared to 22.1% and 20.2% for the three and nine months ended September 30, 2018, will approximate the currentrespectively. We are subject to a 21% statutory U.S. federal corporate income tax rate. Our effective tax rate for the three and nine months interim periods ended September 30, 2019 and 2018 reflect the discrete tax effects of the vesting of RSUs and exercise of options, and the change in fair value of our warrant liability in each period. See Item 1, "Financial Statements - Notes to Condensed Consolidated Financial Statements - Note 9, Income Taxes."
Net Income
Net income was $49.8 million and $121.8 million for the three and nine months ended September 30, 2019, respectively, compared to $24.8 million and $72.4 million for the three and nine months ended September 30, 2018, respectively. The increase in net income primarily relates to growth in total revenues, partially offset by an increase in total expenses and an increase in tax expense.
Diluted EPS was $0.69 and $1.75 for the three and nine months ended September 30, 2019, respectively, compared to $0.36 and $1.07 for the three and nine months ended September 30, 2018, respectively. Diluted EPS increased due to growth in net income, partially offset by an increase in weighted average diluted shares outstanding.

As of September 30, 2018,2019, we had approximately $892.6 million$1.1 billion in cash and investments, including $50.8$43.3 million held by NMIH. The increase in cash and cash equivalents and investments from December 31, 2017 primarily2018 relates to cash generated from operations and net proceeds of approximately $79.2 million from the common stock offering completed in March 2018.

Premiums receivable was $34.7$45.7 million as of September 30, 2018,2019, compared to $25.2$36.0 million as of December 31, 2017.2018. The increase was primarily driven by the increase in our monthly premium policies in force, where premiums are generally paid one month in arrears.
Net deferred policy acquisition costs were $44.4$56.6 million as of September 30, 2018,2019, compared to $37.9$46.8 million atas of December 31, 2017.2018. The increase was primarily driven by growth in the number of policies written during the period ended September 30, 2018 and the deferral of certain costs associated with the origination of those policies, partially offset by the amortization of previously deferred acquisition costs.
Prepaid reinsurance premiums were $33.1$17.9 million as of September 30, 2018,2019, compared to $40.3$30.4 million as of December 31, 2017. The prepaid2018. Prepaid reinsurance premiums, balance representswhich represent the unearned premiums reserve on single premium policies ceded under the 2016 QSR Transaction. The reinsurance coverage periodTransaction, decreased due to the termination of our engagement with one reinsurer under the 2016 QSR Transaction ended for new premiums written after December 31, 2017, and under the 2018 QSR Transaction we cede premiums on singles policies on an earned basis. Consequently, we did not cede any unearned premium reserves on singles policies with coverage effective dates on or after January 1, 2018. The decrease in prepaid reinsurance premiums reflects thecontinued amortization of the unearned premiums, reserve on singles policies previously ceded under the 2016 QSR Transaction.unearned premiums.
Net deferred taxOther assets decreasedincreased to $6.9$35.8 million as of September 30, 2019 from $17.3 million as of December 31, 2018. Other assets as of September 30, 2019 includes $7.6 million of tax and loss bonds and $6.9 million of operating lease right-of-use assets, which we recognized following the adoption of ASU 2016-02, Leases (Topic 842). See Item 1, "Financial Statements - Notes to Condensed Consolidated Financial Statements - Note 9, Income Taxes." and "Financial Statements - Notes to Condensed Consolidated Financial Statements - Note 10, Leases."
Unearned premiums decreased from $158.9 million as of December 31, 2018 to $145.1 million as of September 30, 2019, primarily due to the amortization of existing unearned premiums through earnings in accordance with the expiration of risk on related single premium policies and the cancellation of other single premium policies, partially offset by single premium policy originations during the nine months ended September 30, 2019.
Accounts payable and accrued expenses increased from $19.9$31.1 million as of December 31, 2018 to $39.3 million as of September 30, 2019, primarily due to unsettled payments from the purchase of certain securities and an increase in reinsurance premiums payable, partially offset by the payment of previously accrued compensation.


Reserve for insurance claims and claim expenses increased from $12.8 million as of December 31, 2018 to $20.5 million as of September 30, 2019, primarily due to an increase in NODs tied to the growth in the number of policies in force and the aging of our earlier book years, and an increase in our average reserve per default tied to the aging of our NOD population from non-disaster zones and composition of our default inventory between loans in disaster and non-disaster impacted areas, partially offset by the release of prior year reserves tied to NOD cures and ongoing analysis of recent loss development trends. See "- Insurance Claims and Claim Expenses," abovefor further details.
Reinsurance funds withheld was $16.1 million as of September 30, 2019, representing the net of our ceded reinsurance premiums written, less our profit and ceding commission receivables related to the 2016 QSR Transaction. The decrease in reinsurance funds withheld of $11.0 million from December 31, 2018, relates to the termination of our engagement with one reinsurer under the 2016 QSR Transaction and the continued decline in ceded premiums written on single premium policies, due to the end of the reinsurance coverage period for new business under the 2016 QSR Transaction at December 31, 2017. See Item 1, "Financial Statements - Notes to Condensed Consolidated Financial Statements - Note 5, Reinsurance."
Warrant liability decreased from $7.3 million at December 31, 2017,2018 to $6.4 million at September 30, 2019, primarily due to the utilizationreclassification of net operating loss carryforwardswarrant liability to additional paid-in capital following the exercise of warrants during the period.nine months ended September 30, 2019, partially offset by an increase in our stock price.  For further information regarding the valuation of our warrant liability and its impact on our results of operations and financial position, see Item 1, "Financial Statements - Notes to Condensed Consolidated Financial Statements - Note 3, Fair Value of Financial Instruments."
Net deferred tax liability increased from $2.7 million as of December 31, 2018 to $43.8 million as of September 30, 2019, primarily due to the forecasted deductibility of our statutory contingency reserve in fiscal year 2019. For further information regarding income taxes and their impact on our results of operations and financial position, see Item 1, "Financial Statements - Notes to Condensed Consolidated Financial Statements - Note 9, Income Taxes."
Other assets increased to $17.9 millionliabilities as of September 30, 2018 from $13.72019 include $7.9 million as of December 31, 2017, driven by an increase in accrued investment income and prepaid expenses for various contracts renewals, as well asoperating lease liabilities, which we recognized following the capitalizationadoption of $1.3 million deferred debt issuance costs in connection with the establishment of the 2018 Revolving Credit Facility.
Unearned premiums decreased $0.3 million to $162.9 million as of September 30, 2018, primarily due to the amortization through earnings of existing unearned premiums in accordance with the expiration of risk on the related policies and the cancellation of other single premium policies, partially offset by single premium policy origination during the period.
Accounts payable and accrued expense increased to $27.1 million as of September 30, 2018, from $23.4 million at December 31, 2017, primarily due to an increase in personnel expense and deferred rent accruals, reinsurance premiums payable and unsettled payments from the purchase of certain securities at September 30, 2018.
Reserve for insurance claims and claim expenses increased $2.1 million to $10.9 million at September 30, 2018, primarily due to an increase in the number of new defaults and the aging of existing defaults in our general loan population, offset by the release of reserves on cured defaults. See "- Insurance Claims and Claims Expenses," abovefor further details.

Holding Company Liquidity and Capital Resources
NMIH serves as the holding company for our insurance subsidiaries and does not have any significant operations of its own. NMIH's principal liquidity demands include funds for: (i) payment of certain corporate expenses; (ii) payment of certain reimbursable expenses of its insurance subsidiaries; (iii) payment of principal interest and other feesinterest related to the 2018 Term Loan and 2018


Revolving Credit Agreement;Facility; (iv) tax payments to the Internal Revenue Service; (v) capital support for its subsidiaries; and (vi) payment of dividends, if any, on its common stock. NMIH is not subject to any limitations on its ability to pay dividends except those generally applicable to corporations such as NMIH, that are incorporated in Delaware. Delaware corporation law provides that dividends are only payable out of a corporation's surplus or recent net profits (subject to certain limitations).
As of September 30, 2018,2019, NMIH had $50.8$43.3 million of cash and investments. NMIH's principal source of net operating cash is investment income. NMIH also has access to the $85 million of undrawn revolving credit capacity under the 2018 Revolving Credit Facility and in$2.7 million of ordinary course dividend capacity from Re One. In the future, NMIH could benefit from dividendsdividend capacity from NMIC, and Re One, ifas available and permitted under law and by the GSEs.
In March 2018, NMIH completed the sale of 4.3 million shares of common stock, including the exercise of a 15% overallotment option to purchase additional shares, and raised proceeds of approximately $79.2 million, net of underwriting discounts, commissions and other direct offering expenses. In April, 2018, NMIH made a capital contribution of $70 million to NMIC.
NMIH has entered into tax and expense-sharing agreements with its subsidiaries which have been approved by the Wisconsin OCI, but such approval may be changed or revoked at any time. With the Wisconsin OCI's approval, NMIH began allocating the interest expense on itsthe 2015 Term Loan to NMIC in the first quarter of 2017, consistent with the benefits NMIC received when NMIH down-streamedcontributed the loan proceeds to NMIC. NMIH received similar approval from the Wisconsin OCI to allocate interest expense to NMIC on the 2018 Term Loan and 2018 Revolving Credit Facility.
Our insurance subsidiaries'NMIC and Re One's ability to pay dividends to NMIH is subject to insurance department notice or approval. Under Wisconsin law, insurance companiesNMIC and Re One may pay dividends up to specified levels (i.e., "ordinary" dividends) with 30 days' prior notice to the Wisconsin OCI. Dividends in larger amounts, or "extraordinary" dividends, are subject to the Wisconsin OCI's prior approval. Under Wisconsin insurance laws, an extraordinary dividend is defined as any payment or distribution that together with other dividends and distributions made within the preceding 12 months exceeds the lesser of (i) 10% of the insurer's statutory policyholders' surplus as of the preceding December 31 or (ii) adjusted statutory net income for the 12-month period ending the preceding December 31.
NMIC has never paid any dividends to NMIH. NMIC reported a statutory net loss for the 12 monthsyear ended December 31, 20172018 and cannot pay any dividends to NMIH through December 31, 20182019 without the prior approval of the Wisconsin OCI. Re One has never paid dividends to NMIH. Re One currently has the capacity to pay ordinary dividends of $505 thousandup to NMIH.$2.7 million to NMIH through December 31, 2019. Certain other states in which NMIC and Re One are licensed also have statutes or regulations that may restrict their ability to pay dividends.
As an approved insurer under PMIERs, NMIC would be subject to additional restrictions on its ability to pay dividends to NMIH if it failed to meet the financial requirements prescribed by PMIERs. Approved insurers that fail to meet the PMIERs financial requirements are not permitted to pay dividends without prior approval of the GSEs.
NMIC's capital needs depend on many factors including its ability to successfully write new business, establish premium rates at levels sufficient to cover claims and operating costs and meet minimum required asset thresholds under the PMIERs and minimum state capital requirements. NMIC's capital needs also depend on its decision to access the reinsurance markets. NMIH may require liquidity to fund the capital needs of its insurance subsidiaries.
OnIn May 24, 2018, NMIH entered into the 2018 Credit Agreement covering the 2018 Term Loan and 2018 Revolving Credit Facility. The 2018 Term Loan bears interest at the Eurodollar Rate, as defined in the 2018 Credit Agreement and subject to a 1.00% floor, plus an annual margin rate of 4.75%, payable monthly based on our current interest period election. Borrowings under the 2018 Revolving Credit Facility will accrue interest at a variable rate equal to, at our discretion, (i) a base rate (as defined in the 2018 Credit Agreement, subject to a floor of 1.00% per annum) plus a margin of 1.00% to 2.50% per annum, based on the applicable corporate credit rating at the time, or (ii) the Eurodollar Rate (subject to a floor of 0.00% per annum) plus a margin of 2.00% to 3.50% per annum, based on the applicable corporate credit rating at the time. The 2018 Revolving Credit AgreementFacility also requires a quarterly commitment fee on the average daily undrawn amount ranging from 0.30% to 0.60%, based on the applicable corporate credit rating at the time.
The 2018 Credit Agreement containsWe are subject to certain covenants forunder the 2018 Term Loan including (but not limited to)and 2018 Revolving Credit Facility. Under the financial covenant of2018 Term Loan (and as defined in the 2018 Credit Agreement), we are subject a maximum debt-to-total capitalization ratio of 35%, and certain covenants for. Under the 2018 Revolving Credit Facility including (but not limited to)(and as defined in the following financial covenants:2018 Credit Agreement), we are subject to a maximum debt-to-total capitalization ratio of 35%, a minimum liquidity requirement, compliance with the PMIERs financial requirements (subject to any GSE-approved waivers), and minimum consolidated net worth and statutory capital requirements. We were in compliance with all covenants as of September 30, 2018.2019.




Consolidated Investment Portfolio
Our primary objectives with respect to our investment portfolio are to preserve capital and generate investment income, while maintaining sufficient liquidity to cover our operating needs. We aim to achieve diversification by type, quality, maturity, and industry. We have adopted an investment policy that defines, among other things, eligible and ineligible investments, concentration limits for asset types, industry sectors, single issuers, and certain credit ratings, and benchmarks for asset duration.
Substantially all of ourOur investment portfolio is held inentirely comprised of fixed maturity instruments. As of September 30, 2018,2019, the fair value of our investment portfolio was $874.4 million.$1.1 billion. We also had an additional $18.2$45.9 million of cash and equivalents as of September 30, 2018.2019. Pre-tax book yield on the investment portfolio for the nine months ended September 30, 20182019 was 2.8%3.1%. The book yield is calculated as period-to-date net investment income divided by the average amortized cost of the investment portfolio. Yield on the investment portfolio is likely to change over time based on movements in interest rates, credit spreads, the duration or mix of our investment portfolio and other factors.

Investment Securities - Other-than-Temporary Impairment (OTTI)
As of September 30, 2019, we held no other-than-temporarily impaired securities. During the nine months ended September 30, 2019, we recognized a $0.4 million OTTI loss in earnings related to the planned sale of a security in a loss position that was disposed of in April 2019. We did not recognize any OTTI losses for the three months ended September 30, 2019 or the three and nine months ended September 30, 2018. There were no credit losses recognized in earnings for which a portion of an OTTI loss was recognized in accumulated other comprehensive income (loss) for the three or nine months ended September 30, 2018.
Other Items
Off-Balance Sheet Arrangements and Contractual Obligations
We had no material off-balance sheet arrangements as of September 30, 2018.2019. In connection with the ILN Transactions, we have certain future contractual commitments to the Oaktown Re and Oaktown Re II,Vehicles, special purpose VIEs that are not consolidated in our financial results. See Item 1, "Financial Statements - Notes to Condensed Consolidated Financial Statements - "Note 5, Reinsurance.Note 1. Organization, Basis of Presentation and Summary of Accounting Principles."


Critical Accounting Estimates
We use accounting principles and methods that conform to GAAP. Where GAAP specifically excludes mortgage insurance we follow general industry practices. We are required to apply significant judgment and make material estimates in the preparation of our financial statements and with regard to various accounting, reporting and disclosure matters. Assumptions and estimates are required to apply these principles where actual measurement is not possible or practical. On an ongoing basis, we evaluate our estimates and assumptions. Our actual results may differ from these estimates under different assumptions or conditions.


We believe that the assumptions and estimates associated with revenue recognition, fair value measurements, our investment portfolio, deferred policy acquisition costs, premium deficiency reserves, income taxes and reserves for insurance claims and claimsclaim expenses warrants and share-based compensation have the greatest potential impact on our consolidated financial statements. Therefore, we consider these to be our critical accounting estimates. There have been no material changes to our critical accounting policies and estimates as compared to the critical accounting policies and estimates described in our 20172018 10-K.




Item 3. Quantitative and Qualitative Disclosures About Market Risk
We own and manage a large portfolio of various holdings, types and maturities. NMIH's principal source of operating cash is investment income. The assets within the investment portfolio are exposed to the same factors that affect overall financial market performance.
We manage market risk via a defined investment policy implemented by our treasury function with oversight from our Board of Director's Risk Committee. Important drivers of our market risk exposure monitored and managed by us include but are not limited to:
Changes to the level of interest rates. Increasing interest rates may reduce the value of certain fixed-rate bonds held in the investment portfolio. Higher rates may cause variable rate assets to generate additional income. Decreasing rates will have the reverse impact. Significant changes in interest rates can also affect persistency and claim rates of our insurance portfolio, and as a result we may determine that our investment portfolio needs to be restructured to better align it with future liabilities and claim payments. Such restructuring may cause investments to be liquidated when market conditions are adverse. Additionally, the changes in Eurodollar based interest rates affect the interest expense related to our debt.
Changes to the term structure of interest rates. Rising or falling rates typically change by different amounts along the yield curve. These changes may have unforeseen impacts on the value of certain assets.
Market volatility/changes in the real or perceived credit quality of investments. Deterioration in the quality of investments, identified through changes to our own or third party (e.g., rating agency) assessments, will reduce the value and potentially the liquidity of investments.
Concentration Risk. If the investment portfolio is highly concentrated in one asset, or in multiple assets whose values are highly correlated, the value of the total portfolio may be greatly affected by the change in value of just one asset or a group of highly correlated assets.
Prepayment Risk. Bonds may have call provisions that permit debtors to repay prior to maturity when it is to their advantage. This typically occurs when rates fall below the interest rate of the debt.

The carrying value of our investment portfolio as of September 30, 20182019 and December 31, 20172018 was $874 million$1.1 billion and $716$911 million, respectively, of which 100% was invested in fixed maturity securities. The primary market risk to our investment portfolio is interest rate risk associated with investments in fixed maturity securities. We mitigate the market risk associated with our fixed maturity securities portfolio by matching the duration of our fixed maturity securities with the expected duration of the liabilities that those securities are intended to support.
As of September 30, 2018,2019, the duration of our fixed income portfolio, including cash and cash equivalents, was 3.38 years, which means that an instantaneous parallel shift (movement up or down) in the yield curve of 100 basis points would result in a change of 3.38% in fair value of our fixed income portfolio. Excluding cash, our fixed income portfolio duration was 3.53 years, which means that an instantaneous parallel shift (movement up or down) in the yield curve of 100 basis points would result in a change of 3.53% in fair value of our fixed income portfolio. Excluding cash, our fixed income portfolio duration was 3.67 years, which means that an instantaneous parallel shift (movement up or down) in the yield curve of 100 basis points would result in a change of 3.67% in fair value of our fixed income portfolio.
We are also subject to market risk related to our 2018 Term Loan and the ILN Transactions. As discussed in Item 1, "Financial Statements - Notes to Condensed Consolidated Financial Statements - Note 4, Debt Obligations," the 2018 Term Loan bears interest at a variable rate and, as a result, increases in market interest rates would generally result in increased interest expense on our outstanding principal.
The risk premium amounts under the ILN Transactions are calculated by multiplying the outstanding reinsurance coverage amount at the beginning of any payment period by a coupon rate, which is the sum of 1-month LIBOR and a risk margin, and then subtracting actual investment income earned on the trust balance during that payment period. An increase in 1-month LIBOR rates would generally increase the risk premium payments, while an increase to money market rates, which directly affect investment income earned on the trust balance, would generally decrease them. Although we expect the two rates to move in tandem, to the extent they do not, it could increase or decrease the risk premium payments that otherwise would be due.




Item 4. Controls and Procedures
Disclosure Controls and Procedures
We maintain disclosure controls and procedures designed to ensure that information required to be disclosed in the reports we file or submit under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the SEC's rules and forms, and that such information is accumulated and communicated to our management, including our Chief Executive Officer and Chief Financial Officer, as appropriate, to allow timely decisions regarding required disclosure.
Our management, including our Chief Executive Officer and Chief Financial Officer, conducted an evaluation of the effectiveness of our disclosure controls and procedures (as defined in Rule 13a-15(e) of the Exchange Act) as of September 30, 20182019 pursuant to Rule 13a-15(e) under the Exchange Act. Management applied its judgment in assessing the costs and benefits of such controls and procedures, which by their nature, can provide only reasonable assurance regarding management's control objectives. Management does not expect that our disclosure controls and procedures will prevent or detect all errors and fraud. A control system, irrespective of how well it is designed and operated, can only provide reasonable assurance and cannot guarantee that it will succeed in its stated objectives.
Based upon that evaluation, our Chief Executive Officer and Chief Financial Officer concluded that, as of September 30, 20182019 our disclosure controls and procedures were effective to provide reasonable assurance that the information required to be disclosed by us in the reports we file or submit under the Exchange Act is recorded, processed, summarized, and reported within the time periods specified in the SEC's rules and forms.
Internal Control Over Financial Reporting
There was no change in our internal control over financial reporting that occurred during the period covered by this report that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.






PART II
Item 1. Legal Proceedings
Certain lawsuits and claims arising in the ordinary course of business may be filed or pending against us or our affiliates from time to time. In accordance with applicable accounting guidance, we establish accruals for all lawsuits, claims and expected settlements when we believe it is probable that a loss has been incurred and the amount of the loss is reasonably estimable. When a loss contingency is not both probable and estimable, we do not establish an accrual. Any such loss estimates are inherently uncertain, based on currently available information and are subject to management’s judgment and various assumptions. Due to the inherent subjectivity of these estimates and unpredictability of outcomes of legal proceedings, any amounts accrued may not represent the ultimate resolution of such matters.
To the extent we believe any potential loss relating to such lawsuits and claims may have a material impact on our liquidity, consolidated financial position, results of operations, and/or our business as a whole and is reasonably possible but not probable, we will disclose information relating to any such potential loss, whether in excess of any established accruals or where there is no established accrual. We will also disclose information relating to any material potential loss that is probable but not reasonably estimable. Where reasonably practicable, we will provide an estimate of loss or range of potential loss. No disclosures are generally made for any loss contingencies that are deemed to be remote.
Based upon information available to us and our review of lawsuits and claims filed or pending against us to date, we have not recognized a material accrual liability for these matters, nor do we currently expect it is reasonably possible that these matters will result in a material liability to the Company. However, the outcome of litigation and other legal and regulatory matters is inherently uncertain, and it is possible that one or more of such matters currently pending or threatened could have an unanticipated material adverse effect on our liquidity, consolidated financial position, results of operations, and/or our business as a whole, in the future.
Item 1A. Risk Factors
Risk factors that affect our business and financial results are discussed in Part I, Item 1A of our 2017 10-K, as updated in our First Quarter 10-Q.2018 10-K. As of the date of this report, we are not aware of any material changes in our risk factors from the risk factors disclosed in our 2017 10-K, as updated in our First Quarter 10-Q.2018 10-K. You should carefully consider the risks and uncertainties described herein and in our 20172018 10-K, and First Quarter 10-Q, which have the potential to affect our business, financial condition, results of operations, cash flows or prospects in a material and adverse manner. The risks described herein and in our 20172018 10-K and First Quarter 10-Q are not the only risks we face, as there are additional risks and uncertainties not currently known to us or that we currently deem to be immaterial which may in the future adversely affect our business, financial condition and/or operating results.
