Forward Looking and Other Statements

All statements in this report that address events, developments or results that we expect or anticipate may occur in the future are “forward looking statements.” Forward looking statements consist of statements that relate to matters other than historical fact. In most cases, forward looking statements may be identified by words such as “believe,” “anticipate” or “expect,” or words of similar import. The risk factors referred to in “Forward Looking Statements and Risk Factors – Location of Risk Factors” in Management’s Discussion and Analysis of Financial Condition and Results of Operations below, may cause our actual results to differ materially from the results contemplated by forward looking statements that we may make. We are not undertaking any obligation to update any forward looking statements or other statements we may make in this document even though these statements may be affected by events or circumstances occurring after the forward looking statements or other statements were made. Therefore no reader of this document should rely on these statements being current as of any time other than the time at which this document was filed with the Securities and Exchange Commission.

MGIC INVESTMENT CORPORATION AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

September 30, 2017

(Unaudited)

Note 1. Nature of Business and Basis of Presentation

MGIC Investment Corporation is a holding company which, through Mortgage Guaranty Insurance Corporation (“MGIC”) is principally engaged in the mortgage insurance business. We provide mortgage insurance to lenders throughout the United States and to government sponsored entities (“GSEs”) to protect against loss from defaults on low down payment residential mortgage loans.

The accompanying unaudited consolidated financial statements of MGIC Investment Corporation and its wholly-owned subsidiaries have been prepared in accordance with the instructions to Form 10-Q as prescribed by the Securities and Exchange Commission (“SEC”) for interim reporting and do not include all of the other information and disclosures required by accounting principles generally accepted in the United States of America (“GAAP”). These statements should be read in conjunction with the consolidated financial statements and notes thereto for the year ended December 31, 2016 included in our Annual Report on Form 10-K. As used below, “we,” “our” and “us” refer to MGIC Investment Corporation’s consolidated operations or to MGIC Investment Corporation, as the context requires.

In the opinion of management the accompanying financial statements include all adjustments, consisting primarily of normal recurring accruals, necessary to fairly state our consolidated financial position and consolidated results of operations for the periods indicated. The consolidated results of operations for the interim period may not be indicative of the results that may be expected for the year ending December 31, 2017 .

Substantially all of our insurance written since 2008 has been for loans purchased by the GSEs. We operate under the Private Mortgage Insurer Eligibility Requirements ("PMIERs") of the GSEs that became effective December 31, 2015 and have been amended from time to time. The financial requirements of the PMIERs require a mortgage insurer’s "Available Assets" (generally only the most liquid assets of an insurer) to equal or exceed its "Minimum Required Assets" (which are based on an insurer's book and are calculated from tables of factors with several risk dimensions and are subject to a floor amount). Based on our interpretation of the PMIERs, as of September 30, 2017 , MGIC’s Available Assets are in excess of its Minimum Required Assets; and MGIC is in compliance with the financial requirements of the PMIERs and eligible to insure loans purchased by the GSEs.

Reclassifications

Certain reclassifications to 2016 amounts have been made in the accompanying financial statements to conform to the 2017 presentation.

Subsequent events

We have considered subsequent events through the date of this filing. See Note 12 - “Loss Reserves” for a discussion of the impact recent hurricane activity is having on our notice of default inventory.

Note 2. New Accounting Pronouncements

Adopted Accounting Standards

Improvements to Employee Share-Based Compensation Accounting

In March 2016, the Financial Accounting Standards Board (“FASB”) issued updated guidance that simplifies several aspects of the accounting for employee share-based compensation including the accounting for income taxes, forfeitures, and statutory tax withholding requirements, as well as classification of related amounts within the statement of cash flows. The updated guidance requires that, prospectively, all tax effects related to share-based compensation be made through the statement of operations at the time of settlement. In contrast, the previous guidance required excess tax benefits to be recognized in paid-in capital. The updated guidance also removes the requirement to delay recognition of a tax benefit until it reduces current taxes payable. This change is required to be applied on a modified retrospective basis, with a cumulative effect adjustment to opening retained earnings. Additionally, all tax related cash flows resulting from share-based compensation are to be reported as operating activities on the statement of cash flows, a change from the existing requirement to present tax benefits as an inflow from financing activities and an outflow from operating activities. Finally, for tax withholding purposes, entities will be allowed to withhold an amount of shares up to the employee’s maximum individual tax rate (as opposed to the minimum statutory tax rate) in the relevant jurisdiction without resulting in liability classification of the award. The change in tax withholding is to be applied on a modified retrospective approach. This updated guidance became effective January 1, 2017. We adopted this guidance in the first quarter of 2017 and because of the adoption:


•	We recognized discrete tax benefits of $1.5 million in the provision for income taxes on our statement of operations for the nine months ended September 30, 2017 related to excess tax benefits upon vesting of share-based awards during the period.


•	We recognized a cumulative effect adjustment in opening retained earnings as of January 1, 2017 related

MGIC Investment Corporation - Q3 2017 | 12

Table of contents

to the recognition of a deferred tax asset related to suspended tax benefits from vesting transactions occurring in prior years and from the elimination of our forfeiture estimate on share-based awards, which was previously applied only to awards with service conditions.


•	We reclassified excess tax benefits related to share-based compensation for 2016 to operating activities from financing activities.


•	We reclassified employee taxes paid for withheld shares for 2016 to financing activities from operating activities.

Prospective Accounting Standards

Stock Compensation - Scope of Modification Accounting

In May 2017, the FASB issued updated guidance related to a change in the terms or conditions (modification) of a share-based award. The updated guidance provides that an entity should account for the effects of a modification unless the fair value and vesting conditions of the modified award and the classification of the award (equity or liability instrument) are the same as the original award immediately before the modification. The updated guidance addresses the current diversity in practice on applying modification accounting, as some entities evaluate whether changes to awards are substantive, which is not prescribed within the current accounting guidance. The updated guidance is effective for annual periods beginning after December 15, 2017, including interim periods within those annual periods. Early adoption is permitted, including adoption in any interim period. We are currently evaluating the impacts the adoption of this guidance will have on our consolidated financial statements, but do not expect it to have a material impact on our consolidated financial statements or disclosures.

Premium Amortization on Purchased Callable Debt Securities

In March 2017, the FASB issued updated guidance to amend the amortization period for certain purchased callable debt securities held at a premium shortening the amortization period to the earliest call date. Under current GAAP, there is diversity in practice in the amortization period for premiums of callable debt securities and in how the potential for exercise of a call is factored into current impairment assessments. This updated guidance aligns with how callable debt securities, in the United States, are generally quoted, priced, and traded assuming a model that incorporates consideration of calls (also referred to as “yield-to-worst” pricing). The updated guidance is effective for annual periods beginning after December 15, 2018, including interim periods within those annual periods. We are currently evaluating the impacts the adoption of this guidance will have on our consolidated financial statements, but do not expect it to have a material impact on our consolidated financial statements or disclosures. We currently account for premium amortization on our purchased callable debt securities on a yield-to-worst basis, which generally aligns with the earliest call date.

Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost

In March 2017, the FASB issued updated guidance that improves the reporting of net benefit cost in the financial statements. The updated guidance requires that an employer report the service cost component in the same financial statement caption as other compensation costs arising from services rendered by employees during the period. The other components of net benefit cost are required to be presented in the statement of operations separately from the service cost component and outside a subtotal of income from operations, if one is presented. Current guidance does not prescribe where the amount of net benefit cost should be presented in an employer’s statement of operations and does not require entities to disclose by line item the amount of net benefit cost that is included in the statement of operations. The updated guidance is effective for annual periods beginning after December 15, 2017, including interim periods within those annual periods. We are currently evaluating the impacts the adoption of this guidance will have on our consolidated financial statements, but do not expect it to have a material impact on our consolidated financial statements or disclosures.

Measurement of Credit Losses on Financial Instruments

In June 2016, the FASB issued updated guidance that requires immediate recognition of estimated credit losses expected to occur over the remaining life of many financial instruments. Entities will be required to utilize a current expected credit losses (“CECL”) methodology that incorporates their forecasts of future economic conditions into their loss estimate unless such forecast is not reasonable and supportable, in which case the entity will revert to historical loss experience. Any allowance for CECL reduces the amortized cost basis of the financial instrument to the amount an entity expects to collect. Credit losses relating to available-for-sale fixed maturity securities are to be recorded through an allowance for credit losses, rather than a write-down of the asset, with the amount of the allowance limited to the amount by which fair value is less than amortized cost. In addition, the length of time a security has been in an unrealized loss position will no longer impact the determination of whether a credit loss exists. The updated guidance is not prescriptive about certain aspects of estimating expected credit losses, including the specific methodology to use, and therefore will require significant judgment in application. The updated guidance is effective for annual periods beginning after December 15, 2019, including interim periods within those annual periods. Early adoption is permitted for annual and interim periods in fiscal years beginning after December 15, 2018. We are currently evaluating the impacts the adoption of this guidance will have on our consolidated financial statements, but do not expect it to have a material impact on our consolidated financial statements or disclosures.

Recognition and Measurement of Financial Assets and Financial Liabilities

In January 2016, the FASB issued updated guidance to address the recognition, measurement, presentation, and disclosure of certain financial instruments. The updated guidance requires equity investments, except those accounted for under the equity method of accounting, that have a readily determinable fair value to be measured at fair value with changes in fair value recognized in net income. Equity investments that do not have readily determinable fair values may be remeasured at fair value either upon the occurrence of an observable price change or upon identification of an impairment. A qualitative assessment for impairment is required for equity investments without readily determinable fair values. The updated guidance also eliminates the requirement to disclose the method and significant assumptions used to estimate the fair value of financial instruments measured at amortized cost on the balance sheet. Further, the updated guidance clarifies that entities should evaluate the need for a valuation allowance on a deferred tax asset related to available-for-sale securities in combination with the entities other deferred tax assets. The updated guidance is effective for annual periods beginning after December 15, 2017, including interim periods within those annual periods and will require recognition of a cumulative effect adjustment at adoption. We do not currently expect the adoption of this guidance to impact our consolidated financial statements or disclosures.

Note 3. Debt

2017 debt transactions

2% Notes

On March 21, 2017, we issued an irrevocable notice of redemption in respect of our outstanding 2% Convertible Senior Notes due on April 1, 2020 (“2% Notes”), with a redemption date of April 21, 2017. In April, holders of approximately $202.5 million of the outstanding principal exercised their rights to convert their notes into shares of our common stock. The remaining $5.1 million of outstanding principal was redeemed for cash. The conversions of the 2% Notes at a rate of 143.8332 shares per $1,000 principal amount resulted in the issuance of approximately 29.1 million shares of our common stock in April. The conversions and cash redemption eliminated our debt obligation. A loss on debt extinguishment of $0.07 million was recognized on the redemption of the $5.1 million of 2% Notes. No gain or loss was recognized from the conversions as the outstanding debt issuance costs associated with the conversions were included in the carrying value of the notes, which was credited to shareholders’ equity at the time of conversion.

Credit Facility

On March 21, 2017, we entered into a Credit Agreement with various lenders which provides for a $175 million unsecured revolving credit facility maturing on March 21, 2020. Revolving credit borrowings bear interest at a floating rate, which will be, at our option, either a eurocurrency rate or a

base rate, in each case plus an applicable margin. The applicable margins are subject to adjustment based on our senior unsecured long-term debt rating, or if we do not have such a rating, our corporate or issuer rating. Amounts under the facility may be borrowed, repaid and reborrowed from time to time until the maturity of the revolving credit facility. Voluntary prepayments and commitment reductions are permitted at any time without fee subject to a minimum dollar requirement and, for outstanding eurocurrency loans, customary breakage costs.

We are required under the Credit Agreement to pay commitment fees on the average daily amount of the unused revolving commitments of the lenders, and an annual administrative fee to the administrative agent. The Credit Agreement contains affirmative, negative and financial covenants which are customary for financings of this type, including, among other things, limits on the creation of liens, limits on the incurrence of indebtedness, restrictions on dispositions, maximum debt-to-capital ratio, minimum consolidated stockholders' equity, minimum policyholder's position of MGIC, and compliance with the financial requirements of the PMIERs. The Credit Agreement includes customary events of default for facilities of this type (with customary grace periods, as applicable) and provides that, upon the occurrence of an event of default, payments of all outstanding loans may be accelerated and/or the lenders' commitments may be terminated. Upon the occurrence of certain insolvency or bankruptcy related events of default, all amounts payable under the Credit Agreement shall automatically become immediately due and payable, and the lenders' commitments will automatically terminate. In addition, upon the occurrence of certain insolvency or bankruptcy related events of default, or the failure to pay interest, principal or fees, the interest rates on all outstanding obligations will be increased.

In March, we borrowed $150 million under the revolving credit facility, to fund a portion of the redemption price of the 2% Notes if holders did not elect to convert their 2% Notes. In April, we repaid the amount borrowed under the revolving credit facility because most holders elected to convert their notes. Costs incurred to enter into the Credit Agreement have been deferred and recorded as Other assets and will be amortized over the term of the Credit Agreement.

5% Notes

On May 1, 2017, our 5% Notes due in 2017 (“ 5% Notes”) matured and we repaid the outstanding $145 million in aggregate par value, plus accrued interest with cash at our holding company.

First nine months 2016 debt transactions

5.75% Notes

In August 2016, we issued $425 million aggregate principal amount of 5.75% Senior Notes due in 2023 (“5.75% Notes”) and received net proceeds, after the deduction of underwriting fees, of $418.1 million . Interest on the 5.75% Notes is payable semi-annually on February 15 and August 15 of each year, commencing on February 15, 2017. In addition to underwriting fees, we incurred approximately $1.2 million of other expenses associated with the issuance of these notes. The net proceeds from the 5.75% Notes issuance were primarily used (i) as cash consideration to purchase a portion of our 2% Notes, and (ii) to repurchase the shares issued as partial consideration in the purchases of our 2% Notes, as further described below. The remaining proceeds were held for general corporate purposes.

2% Notes

In the third quarter of 2016, we entered into privately negotiated agreements to purchase $292.4 million in par value of our outstanding 2% Notes at a purchase price of $362.1 million , plus accrued interest. We funded the purchases with $230.7 million in cash proceeds from the issuance of the 5.75% Notes and by issuing to certain sellers approximately 18.3 million shares of our common stock. The excess of the purchase price over carrying value is reflected as a loss on debt extinguishment on our consolidated statements of operations for the three and nine months ended September 30, 2016. The purchases of the 2% Notes reduced our potentially dilutive shares by approximately 42.1 million shares, without considering the shares issued in partial consideration in the purchase of the 2% Notes or the repurchase of shares to offset such shares issued. For more information about the share repurchases, see Note 13 - “Shareholders’ Equity.”

5% Notes

During the first nine months of 2016, we purchased $188.5 million in aggregate par value of our 5% Notes at an aggregate purchase price of $195.5 million for which we recognized losses on debt extinguishment on our consolidated statement of operations for the nine months ended September 30, 2016. The purchases of the 5% Notes reduced our potentially dilutive shares by approximately 14 million shares.

9% Debentures

In February 2016, MGIC purchased $132.7 million in aggregate par value of our 9% Convertible Junior Subordinated Debentures (9% Debentures”) at a purchase price of $150.7 million . The purchase of the 9% Debentures resulted in an $8.3 million loss on debt extinguishment on the consolidated statement of operations for the nine months ended September 30, 2016, which represents the difference between the fair value and the carrying value of the liability component on the purchase date. Our shareholders’ equity was separately reduced by $6.3 million related to the

reacquisition of the equity component. For GAAP accounting purposes, the 9% Debentures owned by MGIC are considered retired and are eliminated in our consolidated financial statements and the underlying common stock equivalents, approximately 9.8 million shares, are not included in the computation of diluted shares.

Debt obligations

The par value of our long-term debt obligations and their aggregate carrying values as of September 30, 2017 and December 31, 2016 were as follows.

Convertible at any time prior to maturity at the holder’s option, at an initial conversion rate, which is subject to adjustment, of 74.0741 shares per $1,000 principal amount, representing an initial conversion price of approximately $13.50 per share. If a holder elects to convert their debentures, deferred interest owed on the debentures being converted is also converted into shares of our common stock. The conversion rate for any deferred interest is based on the average price that our shares traded at during a 5 -day period immediately prior to the election to convert. In lieu of issuing shares of common stock upon conversion of the debentures, we may, at our option, make a cash payment to converting holders for all or some of the shares of our common stock otherwise issuable upon conversion.

The 5.75% Notes and 9% Debentures are obligations of our holding company, MGIC Investment Corporation, and not of its subsidiaries. The Federal Home Loan Bank Advance (the “FHLB Advance”) is an obligation of MGIC.

Quota share reinsurance

We utilize quota share reinsurance to manage our exposure to losses resulting from our mortgage guaranty insurance policies and to provide reinsurance capital credit under the PMIERs. Our 2017 quota share reinsurance agreement (“2017 QSR Transaction”) provides coverage on new business written January 1, 2017 through December 29, 2017 that meets certain eligibility requirements. Under the agreement we cede losses incurred and premiums on or after the effective date through December 31, 2028, at which time the agreement expires. Early termination of the agreement can be elected by us effective December 31, 2021 for a fee, or under specified scenarios for no fee upon prior written notice including if we will receive less than 90% of the full credit amount under the PMIERs for the risk ceded in any required calculation period.

Our 2015 quota share reinsurance agreement (“2015 QSR Transaction”) covers eligible risk in force written before 2017. The 2015 QSR Transaction cedes losses incurred and premiums through December 31, 2024, at which time the agreement expires. Early termination of the agreement can be elected by us effective December 31, 2018 for a fee, or under specified scenarios for no fee upon prior written notice, including if we will receive less than 90% of the full credit amount under the PMIERs for the risk ceded in any required calculation period.

Each of the reinsurers under our 2015 and 2017 QSR Transactions has an insurer financial strength rating of A- or better by Standard and Poor’s Rating Services, A.M. Best or both. The structure of both the 2017 QSR Transaction and 2015 QSR Transaction is a 30% quota share for all policies covered, with a 20% ceding commission as well as a profit

commission. Generally, under the QSR Transactions, we will receive a profit commission provided that the loss ratio on the loans covered under the agreement remains below 60% .

Following is a summary of our quota share reinsurance agreements, excluding captive agreements discussed below, for the three and nine months ended September 30, 2017 and 2016 .



	Three Months Ended September 30,				Nine Months Ended September 30,
(In thousands)	2017		2016		2017		2016
Ceded premiums written and earned, net of profit commission ⁽¹⁾	$	30,880	$	31,707	$	88,692	$	93,334
Ceded losses incurred	5,879		7,432		14,990		22,015
Ceding commissions ⁽²⁾	12,500		12,137		36,751		35,659
Profit commission	31,621		28,981		95,063		84,963


⁽¹⁾	Under our QSR Transactions, premiums are ceded on an earned and received basis as defined in the agreements.


⁽²⁾	Ceding commissions are reported within Other underwriting and operating expenses, net on the consolidated statements of operations.

Under the terms of QSR Transactions, ceded premiums, ceding commission and profit commission are settled net on a quarterly basis. The ceded premium due after deducting the related ceding commission and profit commission is reported within “Other liabilities” on the consolidated balance sheets.

The reinsurance recoverable on loss reserves related to our QSR Transactions was $35.3 million as of September 30, 2017 and $31.8 million as of December 31, 2016 . The reinsurance recoverable balance is secured by funds on deposit from the reinsurers which are based on the funding requirements of PMIERs that address ceded risk.

Captive reinsurance

In the past, MGIC also obtained captive reinsurance. In a captive reinsurance arrangement, the reinsurer is affiliated with the lender for whom MGIC provides mortgage insurance. As part of our settlement with the Consumer Financial Protection Bureau (“CFPB”) in 2013 and with the Minnesota Department of Commerce in 2015, MGIC has agreed to not enter into any new captive reinsurance agreement or reinsure any new loans under any existing captive reinsurance agreement for a period of ten years subsequent to the respective settlements. In accordance with the CFPB settlement, all of our active captive arrangements were placed into run-off. In addition, the GSEs will not approve any future reinsurance or risk sharing transaction with a mortgage enterprise or an affiliate of a mortgage enterprise.

The reinsurance recoverable on loss reserves related to captive agreements was $11 million as of September 30, 2017 , which was supported by $80 million of trust assets, while as of December 31, 2016 , the reinsurance recoverable

MGIC Investment Corporation - Q3 2017 | 16

Table of contents

on loss reserves related to captive agreements was $19 million , which was supported by $91 million of trust assets. Each captive reinsurer is required to maintain a separate trust account to support the risk it has reinsured on all annual books. MGIC is the sole beneficiary of the trusts.

Note 5. Litigation and Contingencies

Before paying an insurance claim, we review the loan and servicing files to determine the appropriateness of the claim amount. When reviewing the files, we may determine that we have the right to rescind coverage on the loan. In our SEC reports, we refer to insurance rescissions and denials of claims collectively as “rescissions” and variations of that term. In addition, all of our insurance policies provide that we can reduce or deny a claim if the servicer did not comply with its obligations under our insurance policy. We call such reduction of claims “curtailments.” In recent quarters, an immaterial percentage of claims received in a quarter have been resolved by rescissions. In each of 2016 and the first nine months of 2017, curtailments reduced our average claim paid by approximately 5.5% .

Our loss reserving methodology incorporates our estimates of future rescissions, curtailments, and reversals of rescissions and curtailments. A variance between ultimate actual rescission, curtailment and reversal rates and our estimates, as a result of the outcome of litigation, settlements or other factors, could materially affect our losses.

When the insured disputes our right to rescind coverage or curtail claims, we generally engage in discussions in an attempt to settle the dispute. If we are unable to reach a settlement, the outcome of a dispute ultimately would be determined by legal proceedings.

Under ASC 450-20, until a liability associated with settlement discussions or legal proceedings becomes probable and can be reasonably estimated, we consider our claim payment or rescission resolved for financial reporting purposes and do not accrue an estimated loss. Where we have determined that a loss is probable and can be reasonably estimated, we have recorded our best estimate of our probable loss. If we are not able to implement settlements we consider probable, we intend to defend MGIC vigorously against any related legal proceedings.

In addition to matters for which we have recorded a probable loss, we are involved in other discussions and/or proceedings with insureds with respect to our claims paying practices. Although it is reasonably possible that when these matters are resolved we will not prevail in all cases, we are unable to make a reasonable estimate or range of estimates of the potential liability. We estimate the maximum exposure associated with matters where a loss is reasonably possible to be approximately $289 million , although we believe (but can give no assurance that) we will ultimately resolve these matters for significantly less than this amount. This estimate

of our maximum exposure does not include interest or consequential or exemplary damages.

Mortgage insurers, including MGIC, have been involved in litigation and regulatory actions related to alleged violations of the anti-referral fee provisions of the Real Estate Settlement Procedures Act, which is commonly known as RESPA, and the notice provisions of the Fair Credit Reporting Act, which is commonly known as FCRA. While these proceedings in the aggregate have not resulted in material liability for MGIC, there can be no assurance that the outcome of future proceedings, if any, under these laws would not have a material adverse affect on us. In addition, various regulators, including the CFPB, state insurance commissioners and state attorneys general may bring other actions seeking various forms of relief in connection with alleged violations of RESPA. The insurance law provisions of many states prohibit paying for the referral of insurance business and provide various mechanisms to enforce this prohibition. While we believe our practices are in conformity with applicable laws and regulations, it is not possible to predict the eventual scope, duration or outcome of any such reviews or investigations nor is it possible to predict their effect on us or the mortgage insurance industry.

Through a non-insurance subsidiary, we utilize our underwriting skills to provide an outsourced underwriting service to our customers known as contract underwriting. As part of the contract underwriting activities, that subsidiary is responsible for the quality of the underwriting decisions in accordance with the terms of the contract underwriting agreements with customers. That subsidiary may be required to provide certain remedies to its customers if certain standards relating to the quality of our underwriting work are not met, and we have an established reserve for such future obligations. Claims for remedies may be made a number of years after the underwriting work was performed. The underwriting remedy expense for 2016 and the first nine months of 2017 was immaterial to our consolidated financial statements.

In addition to the matters described above, we are involved in other legal proceedings in the ordinary course of business. In our opinion, based on the facts known at this time, the ultimate resolution of these ordinary course legal proceedings will not have a material adverse effect on our financial position or results of operations.

Note 6. Earnings per Share

Basic earnings per share (“EPS”) is calculated by dividing net income by the weighted average number of shares of common stock outstanding. Diluted EPS includes the components of basic EPS and also gives effect to dilutive common stock equivalents. We calculate diluted EPS using the treasury stock method and if-converted method. Under the if-converted method, diluted EPS reflects the potential dilution that could occur if our convertible debt instruments result in the issuance of common stock. The determination of potentially issuable shares does not consider the satisfaction of the conversion requirements and the shares are included in the determination of diluted EPS as of the beginning of the period, if dilutive. During the quarter ended September 30, 2017 , we had 9% Debentures outstanding that could result in potentially issuable shares. For purposes of calculating basic and diluted EPS, vested restricted stock and restricted stock units ("RSUs") are considered outstanding.

The following table reconciles the numerators and denominators used to calculate basic and diluted EPS.

The unrealized losses in all categories of our investments at September 30, 2017 and December 31, 2016 were primarily caused by changes in interest rates between the time of purchase and the respective fair value measurement date. There were 343 and 607 securities in an unrealized loss position at September 30, 2017 and December 31, 2016 , respectively.

During each of the three and nine months ended September 30, 2017 and 2016 there were no other-than-temporary impairments (“OTTI”) recognized. The net realized investment gains (losses) on the investment portfolio were as follows:

Note 8. Fair Value Measurements

Under the authoritative guidance, fair value is disclosed using a fair value hierarchy that prioritizes the inputs to valuation techniques used to measure fair value and categorizes assets and liabilities into Levels 1, 2, and 3 based on inputs available to determine their fair values. 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. This model combines all inputs to arrive at a value assigned to each security. Quality controls are performed by the independent pricing sources throughout this process, which include reviewing tolerance reports, trading information, data changes, and directional moves compared to market moves. In addition, on a quarterly basis, we perform quality controls over values received from the pricing sources which also include reviewing tolerance reports, trading information, data changes, and directional moves compared to market moves. We have not made any adjustments to the prices obtained from the independent pricing sources.

In accordance with fair value accounting guidance, we applied the following fair value hierarchy to measure fair value for assets and liabilities:

Level 1 - Quoted prices for identical instruments in active markets that we can access. Financial assets utilizing Level 1 inputs primarily include U.S. Treasury securities and equity securities.

Level 2 - Quoted prices for similar instruments in active markets that we can access; quoted prices for identical or similar instruments in markets that are not active; and inputs, other than quoted prices, that are observable in the marketplace for the instrument. The observable inputs are used in valuation models to calculate the fair value of the instruments. Financial assets utilizing Level 2 inputs primarily include obligations of U.S. government corporations and agencies, corporate bonds, mortgage-

backed securities, asset-backed securities, and most municipal bonds.

The independent pricing sources utilize these approaches to determine the fair value of the instruments in Level 2 of the fair value hierarchy based on type of instrument:

Corporate Debt & U.S. Government and Agency Bonds are evaluated by surveying the dealer community, obtaining relevant trade data, benchmark quotes and spreads and incorporating this information into the evaluation process.

Obligations of U.S. States & Political Subdivisions are evaluated by tracking, capturing, and analyzing quotes for active issues and trades reported via the Municipal Securities Rulemaking Board records. Daily briefings and reviews of current economic conditions, trading levels, spread relationships, and the slope of the yield curve provide further data for evaluation.

Residential Mortgage-Backed Securities (“RMBS”) are evaluated by monitoring interest rate movements, and other pertinent data daily. Incoming market data is enriched to derive spread, yield and/or price data as appropriate, enabling known data points to be extrapolated for valuation application across a range of related securities.

Commercial Mortgage-Backed Securities (“CMBS”) are evaluated using valuation techniques that reflect market participants’ assumptions and maximize the use of relevant observable inputs including quoted prices for similar assets, benchmark yield curves and market corroborated inputs. The inputs for securities covered, including executed trades, broker quotes, credit information, collateral attributes and/or cash flow waterfall as applicable, are regularly reviewed as part of the evaluation.

Asset-Backed Securities (“ABS”) are evaluated using spreads and other information solicited from market buy- and sell-side sources, including primary and secondary dealers, portfolio managers, and research analysts. Cash flows are generated for each tranche, benchmark yields are determined, and deal collateral performance and tranche level attributes including trade activity, bids, and offer are applied, resulting in tranche-specific prices.

Collateralized loan obligations ("CLO") are evaluated by manager rating, seniority in the capital structure, assumptions about prepayment, default and recovery and their impact on cash flow generation. Loan level net asset values are determined and aggregated for tranches and as a final step, prices are checked against available recent trade activity.

Table of contents

Level 3 - Valuations derived from valuation techniques in which one or more significant inputs or value drivers are unobservable or from par values for equity securities restricted in their ability to be redeemed or sold. The inputs used to derive the fair value of Level 3 securities reflect our own assumptions about the assumptions a market participant would use in pricing an asset or liability. Financial assets utilizing Level 3 inputs primarily include equity securities that can only be redeemed or sold at their par value and only to the security issuer and a state premium tax credit

investment. Our non-financial assets that are classified as Level 3 securities consist of real estate acquired through claim settlement. The fair value of real estate acquired is the lower of our acquisition cost or a percentage of the appraised value. The percentage applied to the appraised value is based upon our historical sales experience adjusted for current trends.

Authoritative guidance over disclosures about the fair value of financial instruments requires additional disclosure for financial instruments not measured at fair value. Certain financial instruments, including insurance contracts, are excluded from these fair value disclosure requirements. The carrying values of cash and cash equivalents (Level 1) and accrued investment income (Level 2) approximated their fair values. Additional fair value disclosures related to our investment portfolio are included in Note 7 – “Investments.”

We have made contributions totaling $9.3 million to our qualified pension plan and supplemental executive retirement plan in 2017.

Note 11. Income Taxes

We have approximately $987.6 million of net operating loss (“NOL”) carryforwards on a regular tax basis and $117.9 million of NOL carryforwards for computing the alternative minimum tax as of September 30, 2017 . Any unutilized carryforwards are scheduled to expire at the end of tax years 2032 through 2033.

We evaluate the realizability of our deferred tax assets including our NOL carryforwards on a quarterly basis. Based on our analysis, we have concluded that all of our deferred tax assets are fully realizable and therefore no valuation allowance existed at September 30, 2017 and December 31, 2016.

Tax Contingencies

As previously disclosed, the Internal Revenue Service (“IRS”) completed examinations of our federal income tax returns for the years 2000 through 2007 and issued proposed assessments for taxes, interest and penalties related to our treatment of the flow-through income and loss from an investment in a portfolio of residual interests of Real Estate Mortgage Investment Conduits (“REMICs”). The IRS indicated that it did not believe that, for various reasons, we had established sufficient tax basis in the REMIC residual interests to deduct the losses from taxable income. We appealed these assessments within the IRS and in August 2010, we reached a tentative settlement agreement with the IRS which was not finalized.

In 2014, we received Notices of Deficiency (commonly referred to as “90 day letters”) covering the 2000-2007 tax years. The Notices of Deficiency reflect taxes and penalties related to the REMIC matters of $197.5 million and at September 30, 2017 , there would also be interest related to these matters of approximately $200.3 million . In 2007, we made a payment of $65.2 million to the United States Department of the Treasury which will reduce any amounts we would ultimately owe. The Notices of Deficiency also reflect additional amounts due of $261.4 million , which are primarily associated with the disallowance of the carryback of the 2009 net operating loss to the 2004-2007 tax years. We believe the IRS included the carryback adjustments as a precaution to keep open the statute of limitations on collection of the tax that was refunded when this loss was carried back, and not because the IRS actually intends to disallow the carryback permanently. Depending on the outcome of this matter, additional state income taxes and state interest may become due when a final resolution is reached. As of September 30, 2017 , those state taxes and interest would approximate $84.1 million . In addition, there could also be state tax penalties. Our total amount of unrecognized tax benefits as of September 30, 2017 is $141.8 million , which represents the tax benefits generated

by the REMIC portfolio included in our tax returns that we have not taken benefit for in our financial statements, including any related interest.

We filed a petition with the U.S. Tax Court contesting most of the IRS' proposed adjustments reflected in the Notices of Deficiency and the IRS filed an answer to our petition which continued to assert their claim. The case has twice been scheduled for trial and in each instance, the parties jointly filed, and the U.S. Tax Court approved (most recently in February 2016), motions for continuance to postpone the trial date. Also in February 2016, the U.S. Tax Court approved a joint motion to consolidate for trial, briefing and opinion, our case with similar cases of Radian Group, Inc., as successor to Enhance Financial Services Group, Inc., et al. The parties informed the Tax Court in August 2017 that they had reached agreement in principle on all issues in the case and were preparing the documentation reflecting the terms of their agreement. The agreed settlement terms will be subject to review by the Joint Committee on Taxation ("JCT") before a settlement can be completed and there is no assurance that a settlement will be completed. Based on information that we currently have regarding the status of our ongoing dispute, we recorded a provision for additional taxes and interest of $28.4 million in the first nine months of 2017.

The total amount of the unrecognized tax benefits, related to our aforementioned REMIC issue that would affect our effective tax rate is $119.8 million . We recognize interest accrued and penalties related to unrecognized tax benefits in income taxes. As of September 30, 2017 and December 31, 2016 , we had accrued $50.8 million and $28.9 million , respectively, for the payment of interest.

Note 12. Loss Reserves

We establish reserves to recognize the estimated liability for losses and loss adjustment expenses (“LAE”) related to defaults on insured mortgage loans. Loss reserves are established by estimating the number of loans in our inventory of delinquent loans that will result in a claim payment, which is referred to as the claim rate, and further estimating the amount of the claim payment, which is referred to as claim severity.

Estimation of losses is inherently judgmental. The conditions that affect the claim rate and claim severity include the current and future state of the domestic economy, including

unemployment and the current and future strength of local housing markets; exposure on insured loans; the amount of time between default and claim filing; and curtailments and rescissions. The actual amount of the claim payments may be substantially different than our loss reserve estimates. Our estimates could be adversely affected by several factors, including a deterioration of regional or national economic conditions, including unemployment, leading to a reduction in borrowers’ income and thus their ability to make mortgage payments, and a drop in housing values which may affect borrower willingness to continue to make mortgage payments when the value of the home is below the mortgage balance. Changes to our estimates could result in a material impact to our consolidated results of operations and financial position, even in a stable economic environment.

The “Losses incurred” section of the table below shows losses incurred on defaults that occurred in the current year and in prior years. The amount of losses incurred relating to defaults that occurred in the current year represents the estimated amount to be ultimately paid on such defaults. The amount of losses incurred relating to defaults that occurred in prior years represents the difference between the actual claim rate and severity associated with those defaults resolved in the current year compared to the estimated claim rate and severity at the prior year-end, as well as a re-estimation of amounts to be ultimately paid on defaults continuing from the end of the prior year. This re-estimation of the claim rate and severity is the result of our review of current trends in the default inventory, such as percentages of defaults that have resulted in a claim, the amount of the claims relative to the average loan exposure, changes in the relative level of defaults by geography and changes in average loan exposure.

Losses incurred on defaults that occurred in the current year decreased in the first nine months of 2017 compared to the same period in 2016 , primarily due to a decrease in the estimated claim rate on recently reported defaults and a decrease in the number of new defaults, net of related cures.

For the nine months ended September 30, 2017 and 2016 we experienced favorable prior year loss reserve development, in large part, due to the resolution of approximately 59% and 54% , respectively, of the prior year default inventory, with improved cure rates.

The “Losses paid” section of the table below shows the amount of losses paid on default notices received in the current year and losses paid on default notices received in prior years. For several years, the average time it took to receive a claim associated with a default had increased significantly from our historical experience of approximately twelve months. This was, in part, due to new loss mitigation protocols established by servicers and to changes in some state foreclosure laws that may include, for example, a requirement for additional review and/or mediation processes. In recent quarters, we have experienced a decline in the average time servicers are utilizing to process

foreclosures, which has reduced the average time to receive a claim associated with new notices of default that do not cure. All else being equal, the longer the period between default and claim filing, the greater the severity.

During the first nine months of 2017 and 2016, our losses paid included amounts paid on commutations of coverage on pools of non-performing loans (“NPLs”) and in 2016, our losses paid also included amounts paid in connection with disputes concerning our claims paying practices. The impacts of the commutations of NPLs and settlements were as follows:


•	2017 - 1,337 notices removed from default inventory with an amount paid of $54 million .


•	2016 - 1,273 notices removed from default inventory with an amount paid of $52 million .

Our estimate of premiums to be refunded on expected claim payments is accrued for separately in “Other Liabilities” on our consolidated balance sheets and approximated $68 million and $85 million at September 30, 2017 and December 31, 2016 , respectively.

The following table provides a reconciliation of beginning and ending loss reserves as of and for the nine months ended September 30, 2017 and 2016 :

⁽¹⁾	A negative number for prior year losses incurred indicates a redundancy of prior year loss reserves. See the following table for more information about prior year loss development.


⁽²⁾	In a termination, the reinsurance agreement is cancelled, with no future premium ceded and amounts for any incurred but unpaid losses paid to us. Amounts paid to (received from) reinsurers result in an increase (decrease) in net losses paid. The change in net losses paid on our losses incurred is offset

by a corresponding change in the reinsurance recoverable, resulting in no net impact on losses incurred.

The prior year development of the reserves in the first nine months of 2017 and 2016 is reflected in the following table.

Default inventory

A rollforward of our primary default inventory for the three and nine months ended September 30, 2017 and 2016 appears in the following table. The information concerning new notices and cures is compiled from monthly reports received from loan servicers. The level of new notice and cure activity reported in a particular month can be influenced by, among other things, the date on which a servicer generates its report, the accuracy of the data provided by servicers, the number of business days in a month, transfers of servicing between loan servicers and whether all servicers have provided the reports in a given month.



	Three months ended September 30,				Nine Months Ended September 30,
	2017		2016		2017		2016
Default inventory at beginning of period	41,317		52,558		50,282		62,633
New notices	15,950		17,607		45,352		50,418
Cures	(13,546	)	(15,556	)	(45,382	)	(50,249	)
Paids (including those charged to a deductible or captive)	(2,195	)	(3,051	)	(7,403	)	(9,619	)
Rescissions and denials	(82	)	(125	)	(277	)	(477	)

Default inventory at end of period	41,235		51,433		41,235		51,433

The decrease in the primary default inventory experienced during 2017 and 2016 was generally across all markets and primarily in book years 2008 and prior. Historically as a default ages it becomes more likely to result in a claim.

Subsequent event

As shown in the table below, we received an increased number of new default notices in October 2017 compared to October 2016 related to loans in locations that the Federal Emergency Management Agency has declared Individual Assistance Disaster Areas (“IADA”) in connection with recent hurricane activity primarily impacting Texas, Florida, and Puerto Rico.



	For the month ended October 31,
	2017	2016
Default notices for loans in IADAs	3,394	637
Other default notices	4,549	4,882
Total default notices	7,943	5,519

The number of consecutive months a borrower is delinquent is shown in the following table.

Consecutive months in default

Primary claims received inventory included in ending default inventory:
	1,063	3	%	1,385	3	%	1,636	3	%


⁽¹⁾	Approximately 45% , 47% , and 48% of the primary default inventory in default for 12 consecutive months or more has been in default for at least 36 consecutive months as of September 30, 2017 , December 31, 2016 , and September 30, 2016 , respectively.


⁽²⁾	The majority of items removed from our default inventory were due to commutations of NPLs during the nine months ended September 30, 2017 were in default for 12 consecutive months or more as of December 31, 2016.

The number of months a loan is in the default inventory can differ from the number of payments that the borrower has not made or is considered delinquent. These differences typically result from a borrower making monthly payments that do not result in the loan becoming fully current. The number of payments that a borrower is delinquent is shown in the following table.

Number of payments delinquent

	September 30, 2017			December 31, 2016			September 30, 2016
3 payments or less	16,916	41	%	18,419	36	%	18,374	36	%

⁽¹⁾	The majority of items removed from our default inventory were due to commutations of NPLs during the nine months ended September 30, 2017 had 12 or more payments delinquent as of December 31, 2016.

Pool insurance default inventory decreased to 1,426 at September 30, 2017 from 1,883 at December 31, 2016 , and 1,979 at September 30, 2016 .

Claims paying practices

Our loss reserving methodology incorporates our estimates of future rescissions and curtailments. A variance between ultimate actual rescission and curtailment rates and our estimates, as a result of the outcome of litigation, settlements or other factors, could materially affect our losses.

Our estimate of premiums to be refunded on expected future rescissions is accrued for separately and is included in “Other liabilities” on our consolidated balance sheets.

For information about discussions and legal proceedings with customers with respect to our claims paying practices see Note 5 – “Litigation and Contingencies.”

Note 13. Shareholders’ Equity

Change in accounting principle

As described in Note 2 - “New Accounting Pronouncements,” during the first quarter of 2017 we adopted the updated guidance of “ Improvements to Employee Share-Based Compensation Accounting .” The adoption of this guidance resulted in an immaterial cumulative effect adjustment to our 2017 beginning retained earnings.

2017 Capital transactions

2% Notes

As described in Note 3 - “Debt,” in April, holders of approximately $202.5 million of the outstanding principal amount of our 2% Notes exercised their rights to convert their notes into shares of our common stock. As a result, we issued approximately 29.1 million shares of our common stock, of which 18.7 million shares were reissued from our treasury stock and 10.4 million were newly issued shares. The conversions of the notes increased our shareholders’ equity by the carrying value of the notes at the time of conversion.

Table of contents

2016 Capital transactions

As described in Note 3 - “Debt,” in the third quarter of 2016, we issued approximately 18.3 million shares of our common stock as consideration for the purchase of certain of our 2% Notes. In the third quarter of 2016, we repurchased an aggregate of approximately 13.5 million shares of our common stock, of which approximately 2.1 million shares were unsettled as of September 30, 2016, at a weighted average price per share of $8.02 , which included commissions. The aggregate purchase price of the shares was $108.1 million , which included approximately $16.5 million of cash settled after September 30, 2016. An additional 4.8 million shares were repurchased in October 2016.

As described in Note 3 - “Debt” the purchase of a portion of our 9% Debentures by MGIC, and corresponding elimination of the purchased 9% Debentures in consolidation, resulted in a reduction to our consolidated shareholders’ equity of approximately $6.3 million . This reduction represented the allocated portion of the consideration paid to reacquire the equity component of the 9% Debentures. The reduction was recognized in paid-in capital and was less than the amount ascribed to paid-in capital at original issuance of the 9% Debentures.

Shareholders Rights Agreement

Our Amended and Restated Rights Agreement dated July 23, 2015 seeks to diminish the risk that our ability to use our NOLs to reduce potential future federal income tax obligations may become substantially limited and to deter certain abusive takeover practices. The benefit of the NOLs would be substantially limited, and the timing of the usage of the NOLs could be substantially delayed, if we were to experience an “ownership change” as defined by Section 382 of the Internal Revenue Code.

Under the Agreement each outstanding share of our Common Stock is accompanied by one Right. The “Distribution Date” occurs on the earlier of ten days after a public announcement that a person has become an “Acquiring Person,” or ten business days after a person announces or begins a tender offer in which consummation of such offer would result in a person becoming an “Acquiring Person.” An “Acquiring Person” is any person that becomes, by itself or together with its affiliates and associates, a beneficial owner of 5% or more of the shares of our Common Stock then outstanding, but excludes, among others, certain exempt and grandfathered persons as defined in the Agreement. The Rights are not exercisable until the Distribution Date. Each Right will initially entitle shareholders to buy one-tenth of one share of our Common Stock at a Purchase Price of $45 per full share (equivalent to $4.50 for each one-tenth share), subject to adjustment. Each exercisable Right (subject to certain limitations) will entitle its holder to purchase, at the Rights’ then-current Purchase Price, a number of our shares of Common Stock (or if after the Shares Acquisition Date, we are acquired in a business

combination, common shares of the acquiror) having a market value at the time equal to twice the Purchase Price. The Rights will expire on August 1, 2018, or earlier as described in the Agreement. The Rights are redeemable at a price of $0.001 per Right at any time prior to the time a person becomes an Acquiring Person. Other than certain amendments, the Board of Directors may amend the Rights in any respect without the consent of the holders of the Rights.

Note 14. Share-Based Compensation

We have certain share-based compensation plans. Under the fair value method, compensation cost is measured at the grant date based on the fair value of the award and is recognized over the service period which generally corresponds to the vesting period. Awards under our plans generally vest over periods ranging from one to three years .

The number of shares granted to employees and the weighted average fair value per share during the periods presented were (shares in thousands):



	Nine months ended September 30,
	2017			2016
	Shares Granted	Weighted Average Share Fair Value		Shares Granted	Weighted Average Share Fair Value

RSUs subject only to service conditions	395	10.41		433	5.67

Note 15. Statutory Information

Statutory Capital Requirements

The insurance laws of 16 jurisdictions, including Wisconsin, our domiciliary state, require a mortgage insurer to maintain a minimum amount of statutory capital relative to the risk in force (or a similar measure) in order for the mortgage insurer to continue to write new business. We refer to these requirements as the “State Capital Requirements.” While they vary among jurisdictions, the most common State Capital Requirements allow for a maximum risk-to-capital ratio of 25 to 1 . A risk-to-capital ratio will increase if (i) the percentage decrease in capital exceeds the percentage decrease in insured risk, or (ii) the percentage increase in capital is less than the percentage increase in insured risk. Wisconsin does not regulate capital by using a risk-to-capital measure but instead requires a minimum policyholder position (“MPP”). The “policyholder position” of a mortgage insurer is its net worth or surplus, contingency reserve and a portion of the reserves for unearned premiums.

full credit for the risk ceded under our reinsurance transactions with a group of unaffiliated reinsurers. It is possible that under the revised State Capital Requirements discussed below, MGIC will not be allowed full credit for the risk ceded to the reinsurers. If MGIC is not allowed an agreed level of credit under either the State Capital Requirements or the financial requirements of the PMIERs, MGIC may terminate the reinsurance transactions, without penalty. At this time, we expect MGIC to continue to comply with the current State Capital Requirements; however, you should read the rest of these financial statement footnotes for information about matters that could negatively affect such compliance.

At September 30, 2017 , the risk-to-capital ratio of our combined insurance operations (which includes a reinsurance affiliate) was 11.1 to 1 . Reinsurance agreements with an affiliate permit MGIC to write insurance with a higher coverage percentage than it could on its own under certain state-specific requirements. A higher risk-to-capital ratio on a combined basis may indicate that, in order for MGIC to continue to utilize reinsurance agreements with its affiliate, additional capital contributions to the reinsurance affiliate could be needed.

We ask the Commissioner of Insurance of the State of Wisconsin (the “OCI”) not to object before MGIC pays dividends. In the third quarter of 2017, MGIC paid a $40 million dividend to our holding company. MGIC is subject to statutory regulations as to payment of dividends. The maximum amount of dividends that MGIC may pay in any twelve-month period without regulatory approval by the OCI is the lesser of adjusted statutory net income or 10% of statutory policyholders’ surplus as of the preceding calendar year end. Adjusted statutory net income is defined for this purpose to be the greater of statutory net income, net of realized investment gains, for the calendar year preceding the date of the dividend or statutory net income, net of realized investment gains, for the three calendar years preceding the date of the dividend less dividends paid within the first two of the preceding three calendar years. The OCI recognizes only statutory accounting practices prescribed or permitted by the State of Wisconsin for determining and reporting the financial condition and results of operations of an insurance company. The OCI has adopted certain prescribed accounting practices that differ from those found in other states. Specifically, Wisconsin domiciled companies record changes in the contingency reserves through the income statement as changes in underwriting deductions. As a result, in periods in which MGIC is increasing contingency reserves, statutory net income is lowered. For the year ended December 31, 2016 , MGIC’s statutory net income was reduced by $490 million to account for the increase in contingency reserves.

The NAIC plans to revise the minimum capital and surplus requirements for mortgage insurers that are provided for in its Mortgage Guaranty Insurance Model Act. In May 2016, a working group of state regulators released an exposure draft of a risk-based capital framework to establish capital requirements for mortgage insurers, although no date has been established by which the NAIC must propose revisions to the capital requirements and certain items have not yet been completely addressed by the framework, including the treatment of ceded risk, minimum capital floors, and action level triggers. Currently, we believe that the PMIERs contain the more restrictive capital requirements in most circumstances.

While MGIC currently meets the State Capital Requirements of Wisconsin and all other jurisdictions, it could be prevented from writing new business in the future in all jurisdictions if it fails to meet the State Capital Requirements of Wisconsin, or it could be prevented from writing new business in another jurisdiction if it fails to meet the State Capital Requirements of that jurisdiction, and in each case MGIC does not obtain a waiver of such requirements. It is possible that regulatory action by one or more jurisdictions, including those that do not have specific State Capital Requirements, may prevent MGIC from continuing to write new insurance in such jurisdictions.

If we are unable to write business in all jurisdictions, lenders may be unwilling to procure insurance from us anywhere. In addition, a lender’s assessment of the future ability of our insurance operations to meet the State Capital Requirements or the PMIERs may affect its willingness to procure insurance from us. A possible future failure by MGIC to meet the State Capital Requirements or the PMIERs will not necessarily mean that MGIC lacks sufficient resources to pay claims on its insurance liabilities. While we believe MGIC has sufficient claims paying resources to meet its claim obligations on its insurance in force on a timely basis, you should read the rest of these financial statement footnotes for information about matters that could negatively affect MGIC’s claims paying resources.

SUMMARY OF THIRD QUARTER AND YEAR TO DATE 2017 RESULTS

Comparative quarterly results

We recorded third quarter 2017 net income of $120.0 million , or $0.32 per diluted share. Net income increased by $63.4 million compared with net income of $56.6 million in the prior year, due to lower losses incurred, net and the prior year having losses from debt extinguishment transactions. In addition, our diluted weighted average shares outstanding decreased from the prior year due to reductions in our convertible debt outstanding, resulting in a 129% increase in diluted income per share.

Adjusted net operating income for the third quarter 2017 was $120.7 million ( Q3 2016 : $102.4 million ) and adjusted net operating income per diluted share was $0.32 ( Q3 2016 : $0.25 ). The 18% increase in adjusted net operating income was driven primarily by lower losses incurred, net. In addition to the increase in adjusted net operating income, our diluted weighted average shares outstanding decreased from the prior year, resulting in a 28% increase in adjusted net operating income per diluted share.

Losses incurred, net were $29.7 million , down 51% compared to the prior year. New delinquency notices in the third quarter were 9% lower than the prior year and the claim rate applied to the new notices was approximately 11%, down from approximately 12% in the prior year. Our estimated claim rate on new notices reflects the current economic environment and anticipated cure activity on the notices received.

Loss on debt extinguishment in the prior year period reflects the repurchases of our 2% Notes at an amount in excess of our carrying value.

The increase in our provision for income taxes in the third quarter of 2017 as compared to the same period in the prior year was primarily due to an increase in our income before tax.

In September 2017, MGIC paid a dividend of $40 million to our holding company and we expect MGIC to continue to pay quarterly dividends.

Comparative year to date results

We recorded net income of $328.4 million , or $0.86 per diluted share during the first nine months 2017 . Net income increased by $93.4 million compared with net income of $235.0 million in the same period of 2016 , primarily due to lower losses incurred, net and the prior year significant losses from debt extinguishment transactions, partially offset by an increase in our effective tax rate discussed below. In addition, our diluted weighted average shares outstanding decreased from the prior year due to reductions in our convertible debt outstanding, resulting in a 48% increase in diluted income per share.

Adjusted net operating income for the first nine months of 2017 was $357.0 million (2016: $288.6 million ) and adjusted net operating income per diluted share was $0.93 (2016: $0.71 ). The 24% increase in adjusted net operating income was driven primarily by lower losses incurred, net. In addition to the increase in adjusted net operating income, our weighted average shares outstanding decreased from the prior year, resulting in a 31% increase in adjusted net operating income per diluted share.

Table of contents

Losses incurred, net were $84.7 million , down 56% compared to the prior year. New delinquency notices in the first nine months of 2017 were 10% lower than the prior year and the claim rate applied to the new notices was approximately 11%, down from approximately 13% in the prior year.

Loss on debt extinguishment in the prior year reflects the repurchases of a portion of our outstanding 2% and 5% Notes at amounts above our carrying values. The loss on debt extinguishment from MGIC’s purchase of our 9% Debentures represents the difference between the fair value and carrying value of the liability component on the purchase date.

The increase in our provision for income taxes for the first nine months of 2017 as compared to the prior year was the result of an increase in our income before tax and an additional provision recorded for the expected settlement of our IRS litigation as more fully described in Note 11 - “Income Taxes” to our consolidated financial statements. Excluding the additional provision and interest related to our IRS litigation, the effective tax rate was approximately 33.8% in the first nine months of 2017, compared to 33.2% in the prior year period.

See “Consolidated Results of Operations” below for additional discussion of our results for the three and nine months ended September 30, 2017 compared to the respective prior year periods.

CAPITAL

The following debt transactions have been completed during 2017:

•

2% Notes - In April, holders of approximately $202.5 million of the outstanding principal amount of the notes exercised their rights to convert their notes to shares of our common stock and we issued approximately 29.1 million shares of our common stock, which included newly issued shares and the reissuance of treasury stock. The remaining $5.1 million of outstanding principal amount of the notes was redeemed for cash. The conversions and cash redemptions eliminated our debt obligation for the 2% Notes and the conversions increased our shareholders’ equity by the carrying value of the converted notes. The notes redeemed for cash eliminated approximately 0.7 million potentially dilutive shares. These shares were included in our calculation of diluted weighted average shares and diluted EPS up to the date of the notes redemption.


•	5% Notes - On May 1, 2017, our 5% Notes matured and were repaid with $145 million of holding company cash. The repayment of our 5% Notes eliminated approximately 10.8 million potentially dilutive shares. These shares were included in our calculation of diluted weighted average shares and diluted EPS up to the date of the notes repayment.


•	Revolving credit facility - In March, we borrowed $150 million on our revolving credit facility to fund, if

necessary, the redemption price of our 2% Notes. In April, we repaid the amount borrowed because most holders of our 2% Notes elected to convert their notes.

The above 2% and 5% Notes transactions, along with net income generated in the first nine months of 2017, reduced our long-term debt to shareholders’ equity ratio to approximately 27% as of September 30, 2017, down from approximately 47% as of December 31, 2016.

GSEs

We must comply with the PMIERs to be eligible to insure loans purchased by the GSEs. The PMIERs include financial requirements, as well as business, quality control and certain transaction approval requirements. The financial requirements of the PMIERs require a mortgage insurer’s Available Assets to equal or exceed its Minimum Required Assets. Based on our interpretation of the PMIERs, as of September 30, 2017 , MGIC’s Available Assets totaled $4.7 billion , an excess of $0.8 billion over its Minimum Required Assets. MGIC is in compliance with the PMIERs and eligible to insure loans purchased by the GSEs. Beginning in October 2017, we have begun to receive an increased number of new default notices related to loans in locations that FEMA has declared IADAs in connection with recent hurricane activity primarily impacting Texas, Florida, and Puerto Rico. As a result, our excess Available Assets may decline as the PMIERS require us to maintain significantly more Minimum Required Assets for delinquent loans than for performing loans.

If MGIC ceases to be eligible to insure loans purchased by one or both of the GSEs, it would significantly reduce the volume of our new business writings. Factors that may negatively impact MGIC’s ability to continue to comply with the financial requirements of the PMIERs include the following:

•

The GSEs could make the PMIERs more onerous in the future; in this regard, the PMIERs provide that the factors that determine Minimum Required Assets will be updated every two years and may be updated more frequently to reflect changes in macroeconomic conditions or loan performance. The GSEs have informed us that they currently do not expect any updates to be effective before the fourth quarter of 2018 and we expect the GSEs will provide notice 180 days prior to the effective date of such updates. The GSEs may amend the PMIERs at any time.

•

The GSEs may reduce the amount of credit they allow under the PMIERs for the risk ceded under our quota share reinsurance transactions. The GSEs’ ongoing approval of those transactions is subject to several conditions and the transactions will be reviewed under the PMIERs at least annually by the GSEs. For more information about the transactions, see Note 4 - “Reinsurance” to our consolidated financial statements.

Table of contents


•	Our future operating results may be negatively impacted by the matters discussed in our risk factors. Such matters could decrease our revenues, increase our losses or require the use of assets, thereby creating a shortfall in Available Assets.


•	Should capital be needed by MGIC in the future, capital contributions from our holding company may not be available due to competing demands on holding company resources, including for repayment of debt.

While on an overall basis, the amount of Available Assets MGIC must hold in order to continue to insure GSE loans increased under the PMIERs over what state regulation currently requires, our reinsurance transactions mitigate the negative effect of the PMIERs on our returns. In this regard, see the second bullet point above.

State Regulations

The insurance laws of 16 jurisdictions, including Wisconsin, MGIC’s domiciliary state, require a mortgage insurer to maintain a minimum amount of statutory capital relative to its risk in force (or a similar measure) in order for the mortgage insurer to continue to write new business. We refer to these requirements as the “State Capital Requirements.” While they vary among jurisdictions, the most common State Capital Requirements allow for a maximum risk-to-capital ratio of 25 to 1. A risk-to-capital ratio will increase if (i) the percentage decrease in capital exceeds the percentage decrease in insured risk, or (ii) the percentage increase in capital is less than the percentage increase in insured risk. Wisconsin does not regulate capital by using a risk-to-capital measure but instead requires an MPP.

At September 30, 2017 , MGIC’s risk-to-capital ratio was 10.1 to 1, below the maximum allowed by the jurisdictions with State Capital Requirements, and its policyholder position was $1.9 billion above the required MPP of $1.2 billion . In calculating our risk-to-capital ratio and MPP, we are allowed full credit for the risk ceded under our reinsurance transactions with a group of unaffiliated reinsurers. It is possible that under the revised State Capital Requirements discussed below, MGIC will not be allowed full credit for the risk ceded to the reinsurers. If MGIC is not allowed an agreed level of credit under either the State Capital Requirements or the PMIERs, MGIC may terminate the reinsurance transactions, without penalty. At this time, we expect MGIC to continue to comply with the current State Capital Requirements; however, refer to our risk factor titled “State capital requirements may prevent us from continuing to write new insurance on an uninterrupted basis” for more information about matters that could negatively affect such compliance.

requirements for mortgage insurers, although no date has been established by which the NAIC must propose revisions to the capital requirements and certain items have not yet been completely addressed by the framework, including the treatment of ceded risk, minimum capital floors, and action level triggers. Currently we believe that the PMIERs contain the more restrictive capital requirements in most circumstances.

GSE REFORM

The FHFA has been the conservator of the GSEs since 2008 and has the authority to control and direct their operations. The increased role that the federal government has assumed in the residential housing finance system through the GSE conservatorship may increase the likelihood that the business practices of the GSEs change in ways that have a material adverse effect on us and that the charters of the GSEs are changed by new federal legislation. In the past, members of Congress have introduced several bills intended to change the business practices of the GSEs and the FHA; however, no legislation has been enacted. The Administration has indicated that the conservatorship of the GSEs should end; however, it is unclear whether and when that would occur and how that would impact us. As a result of the matters referred to above, it is uncertain what role the GSEs, FHA and private capital, including private mortgage insurance, will play in the residential housing finance system in the future or the impact of any such changes on our business. In addition, the timing of the impact of any resulting changes on our business is uncertain. Most meaningful changes would require Congressional action to implement and it is difficult to estimate when Congressional action would be final and how long any associated phase-in period may last.

For additional information about the business practices of the GSEs, see our risk factor titled “Changes in the business practices of the GSEs, federal legislation that changes their charters or a restructuring of the GSEs could reduce our revenues or increase our losses.”

LOAN MODIFICATIONS AND OTHER SIMILAR PROGRAMS

The federal government, including through the U.S. Department of the Treasury and the GSEs, and several lenders have modification and refinance programs to make loans more affordable to borrowers with the goal of reducing the number of foreclosures. These programs have included HAMP, which expired at the end of 2016, and HARP, which is scheduled to expire at the end of 2018. The GSEs have introduced other loan modification programs to replace HAMP.

From 2008 through 2012, we were notified of modifications that cured delinquencies that, had they become paid claims, would have resulted in a material increase in our incurred losses. More recently, the number of modifications has decreased significantly. Nearly all of the reported loan modifications were for loans insured in 2009 and prior.

MGIC Investment Corporation - Q3 2017 | 34

Table of contents

We cannot determine the total benefit we may derive from loan modification programs, particularly given the uncertainty around the re-default rates for defaulted loans that have been modified. Our loss reserves do not account for potential re-defaults of current loans.

As shown in the following table, as of September 30, 2017 approximately 16% of our primary RIF has been modified.

As of September 30, 2017 , based on loan count, the loans associated with 97.6% of HARP modifications and 76.9% of HAMP and other modifications were current.

FACTORS AFFECTING OUR RESULTS

Our results of operations are affected by:

Premiums written and earned

Premiums written and earned in a year are influenced by:

•

NIW, which increases IIF, is the aggregate principal amount of the mortgages that are insured during a period. Many factors affect NIW, including the volume of low down payment home mortgage originations and competition to provide credit enhancement on those mortgages, including competition from the FHA, the VA, other mortgage insurers, GSE programs that may reduce or eliminate the demand for mortgage insurance and other alternatives to mortgage insurance. NIW does not include loans previously insured by us that are modified, such as loans modified under HARP.

•

Cancellations, which reduce IIF. Cancellations due to refinancings are affected by the level of current mortgage interest rates compared to the mortgage coupon rates throughout the in force book, current home values compared to values when the loans in the in force book were insured and the terms on which mortgage credit is available. Home price appreciation can give homeowners the right to cancel mortgage insurance on their loans if sufficient home equity is achieved. Cancellations also result from policy rescissions, which require us to return any premiums received on the rescinded policies and claim payments, which require us

to return any premium received on the related policies from the date of default on the insured loans. Cancellations of single premium policies, which are generally non-refundable, results in immediate recognition of any remaining unearned premium.

•

Premium rates, which are affected by product type, competitive pressures, the risk characteristics of the insured loans and the percentage of coverage on the insured loans. The substantial majority of our monthly and annual mortgage insurance premiums are under premium plans for which, for the first ten years of the policy, the amount of premium is determined by multiplying the initial premium rate by the original loan balance; thereafter, the premium resets and a lower premium rate is used for the remaining life of the policy. However, for loans that have utilized HARP, the initial ten-year period resets as of the date of the HARP transaction. The remainder of our monthly and annual premiums are under premium plans for which premiums are determined by a fixed percentage of the loan’s amortizing balance over the life of the policy.


•	Premiums ceded, net of a profit commission, under reinsurance agreements. See Note 4 - “Reinsurance” to our consolidated financial statements for a discussion of our reinsurance agreements.

Premiums are generated by the insurance that is in force during all or a portion of the period. A change in the average IIF in the current period compared to an earlier period is a factor that will increase (when the average in force is higher) or reduce (when it is lower) premiums written and earned in the current period, although this effect may be enhanced (or mitigated) by differences in the average premium rate between the two periods as well as by premiums that are returned or expected to be returned in connection with claim payments and rescissions, and premiums ceded under reinsurance agreements. Also, NIW and cancellations during a period will generally have a greater effect on premiums written and earned in subsequent periods than in the period in which these events occur.

Investment income

Our investment portfolio is composed principally of investment grade fixed income securities. The principal factors that influence investment income are the size of the portfolio and its yield. As measured by amortized cost (which excludes changes in fair value, such as from changes in interest rates), the size of the investment portfolio is mainly a function of cash generated from (or used in) operations, such as NPW, investment income, net claim payments and expenses, and cash provided by (or used for) non-operating activities, such as debt or stock issuances or repurchases.

Losses incurred

Losses incurred are the current expense that reflects estimated payments that will ultimately be made as a result

35 | MGIC Investment Corporation - Q3 2017

Table of contents

of delinquencies on insured loans. As explained under “Critical Accounting Policies” in our 10-K MD&A, except in the case of a premium deficiency reserve, we recognize an estimate of this expense only for delinquent loans. The level of new delinquencies has historically followed a seasonal pattern, with new delinquencies in the first part of the year lower than new delinquencies in the latter part of the year, though this pattern can be affected by the state of the economy and local housing markets. Losses incurred are generally affected by:


•	The state of the economy, including unemployment and housing values, each of which affects the likelihood that loans will become delinquent and whether loans that are delinquent cure their delinquency.


•	The product mix of the in force book, with loans having higher risk characteristics generally resulting in higher delinquencies and claims.


•	The size of loans insured, with higher average loan amounts tending to increase losses incurred.


•	The percentage of coverage on insured loans, with deeper average coverage tending to increase incurred losses.


•	The rate at which we rescind policies or curtail claims. Our estimated loss reserves incorporate our estimates of future rescissions of policies and curtailments of claims, and reversals of rescissions and curtailments. We collectively refer to such rescissions and denials as “rescissions” and variations of this term. We call reductions to or denials of claims “curtailments.”

•

The distribution of claims over the life of a book. Historically, the first few years after loans are originated are a period of relatively low claims, with claims increasing substantially for several years subsequent and then declining, although persistency, the condition of the economy, including unemployment and housing prices, and other factors can affect this pattern. For example, a weak economy or housing value declines can lead to claims from older books increasing, continuing at stable levels or experiencing a lower rate of decline. See further information under “Mortgage Insurance Earnings and Cash Flow Cycle” below.


•	Losses ceded under reinsurance agreements. See Note 4 - “Reinsurance” to our consolidated financial statements for a discussion of our reinsurance agreements.

Underwriting and other expenses

Most of our operating expenses are fixed, with some variability due to contract underwriting volume. Contract underwriting generates fee income included in “Other revenue.” Underwriting and other expenses are net of any ceding commission associated with our reinsurance agreements. See Note 4 - “Reinsurance” to our consolidated

financial statements for a discussion of our reinsurance agreements.

Interest expense

Interest expense reflects the interest associated with our outstanding debt obligations. For information about our outstanding debt obligations, see Note 3 - “Debt” to our consolidated financial statements and under “Liquidity and Capital Resources” below.

Other

Certain activities that we do not consider being part of our fundamental operating activities, may also impact our results of operations and are described below.

Net realized investment gains (losses)

Realized gains and losses are a function of the difference between the amount received on the sale of a security and the security’s cost basis, as well as any “other than temporary” impairments (“OTTI”) recognized in earnings. The amount received on the sale of fixed income securities is affected by the coupon rate of the security compared to the yield of comparable securities at the time of sale.

Loss on debt extinguishment

At times, we may undertake activities to enhance our capital position, improve our debt profile and/or reduce potential dilution from our outstanding convertible debt. Extinguishing our outstanding debt obligations early through these discretionary activities may result in losses primarily driven by the payment of consideration in excess of our carrying value.

Refer to “Explanation and reconciliation of our use of Non-GAAP financial measures” below to understand how these items impact our evaluation of our core financial performance.

MORTGAGE INSURANCE EARNINGS AND CASH FLOW CYCLE

In general, the majority of any underwriting profit that a book generates occurs in the early years of the book, with the largest portion of any underwriting profit realized in the first year following the year the book was written. Subsequent years of a book generally result in either less underwriting profit or in underwriting losses. This pattern of results typically occurs because relatively few of the claims that a book will ultimately experience typically occur in the first few years of the book, when premium revenue is highest, while subsequent years are affected by declining premium revenue, as the number of insured loans decreases (primarily due to loan prepayments) and increasing losses. The typical pattern is also a function of premium rates generally resetting to lower levels after ten years.

Explanation and reconciliation of our use of non-GAAP financial measures

Non-GAAP financial measures

We believe that use of the Non-GAAP measures of adjusted pre-tax operating income (loss), adjusted net operating income (loss) and adjusted net operating income (loss) per diluted share facilitate the evaluation of the company's core financial performance thereby providing relevant information to investors. These measures are not recognized in accordance with GAAP and should not be viewed as alternatives to GAAP measures of performance.

Adjusted pre-tax operating income (loss) is defined as GAAP income (loss) before tax, excluding the effects of net realized investment gains (losses), gain (loss) on debt extinguishment, net impairment losses recognized in income (loss) and infrequent or unusual non-operating items where applicable.

Adjusted net operating income (loss) is defined as GAAP net income (loss) excluding the after-tax effects of net realized investment gains (losses), gain (loss) on debt extinguishment, net impairment losses recognized in income (loss), and infrequent or unusual non-operating items where applicable. The amounts of adjustments to components of pre-tax operating income (loss) are tax effected using a federal statutory tax rate of 35%.

Adjusted net operating income (loss) per diluted share is calculated in a manner consistent with the accounting standard regarding earnings per share by dividing (i) adjusted net operating income (loss) after making adjustments for interest expense on convertible debt, whenever the impact is dilutive by (ii) diluted weighted average common shares outstanding, which reflects share dilution from unvested restricted stock units and from convertible debt when dilutive under the “if-converted” method.

Although adjusted pre-tax operating income (loss) and adjusted net operating income (loss) exclude certain items that have occurred in the past and are expected to occur in the future, the excluded items represent items that are: (1) not viewed as part of the operating performance of our primary activities; or (2) impacted by both discretionary and other economic factors and are not necessarily indicative of operating trends, or both. These adjustments, along with the reasons for their treatment, are described below. Trends in the profitability of our fundamental operating activities can be more clearly identified without the fluctuations of these adjustments. Other companies may calculate these measures differently. Therefore, their measures may not be comparable to those used by us.


(1)	Net realized investment gains (losses). The recognition of net realized investment gains or losses can vary significantly across periods as the timing of individual securities sales is highly discretionary and is influenced by such factors as market opportunities, our tax and capital profile, and overall market cycles.


(2)	Gains and losses on debt extinguishment. Gains and losses on debt extinguishment result from discretionary activities that are undertaken to enhance our capital position, improve our debt profile, and/or reduce potential dilution from our outstanding convertible debt.


(3)	Infrequent or unusual non-operating items. Income tax expense related to our IRS dispute is related to past transactions which are non-recurring in nature and are not part of our primary operating activities.

Mortgage Insurance Portfolio

NEW INSURANCE WRITTEN

According to Inside Mortgage Finance and GSE estimates , total mortgage originations for the third quarter and first nine months of 2017 decreased from the respective prior year periods due to a decline in refinance originations that was only partially offset by an increase in purchase originations. The total amount of mortgage originations is generally influenced by the level of new and existing home sales, the percentage of homes purchased for cash, and the level of refinance activity. PMI market share of total mortgage originations is generally influenced by the mix of purchase and refinance originations as PMI market share is 3-4 times higher for purchase originations than refinance originations. PMI market share is also impacted by the market share of total originations for FHA, VA, and USDA.

NIW for the third quarter of 2017 was $14.1 billion ( Q3 2016 : $14.2 billion ) and for the first nine months of 2017 was $36.3 billion (YTD 2016 : $35.1 billion ) and continued to have what we believe are favorable risk characteristics (see tables 01 and 02 ). The percentage of purchase mortgages insured increased in the three and nine months ended September 30, 2017 compared to the same periods of the prior year because the level of refinance transactions declined as mortgage interest rates in the current year were generally higher than those in 2016, particularly in the third quarter of 2016 when rates neared historic lows (see table 04 ).

INSURANCE AND RISK IN FORCE (see table 05 )

The amount of our IIF and RIF is impacted by the amount of NIW and cancellations of primary IIF during the period. Cancellation activity is primarily due to refinancing activity, but is also impacted by rescissions, cancellations due to claim payment, and policies cancelled when borrowers achieve the required amount of home equity. Refinancing activity has historically been affected by the level of mortgage interest rates and the level of home price appreciation. Cancellations generally move inversely to the change in the direction of interest rates, although they generally lag a change in direction.

Persistency

Our persistency was 78.8% at September 30, 2017 compared to 76.9% at December 31, 2016 and 78.3% at September 30, 2016 . Since 2000, our year-end persistency ranged from a high of 84.7% at December 31, 2009 to a low of 47.1% at December 31, 2003. With the current and expected level of mortgage interest rates we expect a low level of refinance activity and that our persistency will increase gradually in subsequent periods.

CREDIT PROFILE OF OUR PRIMARY RIF (see table 06 )

Our total primary RIF written after 2008 as a percentage of total primary RIF has been steadily increasing. Our 2009 and later books possess significantly improved credit characteristics when compared to our 2005-2008 books. The loans we insured beginning in 2009, on average, have substantially higher FICO scores and lower LTVs than those insured in 2005-2008. The credit profile of our RIF has also benefited from programs such as HARP. HARP allows borrowers who are not delinquent, but who may not otherwise be able to refinance their loans under the current GSE underwriting standards, due to, for example, the current LTV exceeding 100%, to refinance and lower their note rate. Loans associated with 97.6% of all of our HARP modifications were current as of September 30, 2017 . The aggregate of our 2009-2017 book years and our HARP modifications accounted for approximately 85% of our total primary RIF at September 30, 2017 (see table 06 ).

Pool insurance

MGIC has written no new pool insurance since 2009, however, for a variety of reasons, including responding to capital market alternatives to PMI and customer demands, MGIC may write pool risk in the future. Our direct pool risk in force was $489 million ( $238 million on pool policies with aggregate loss limits and $251 million on pool policies without aggregate loss limits) at September 30, 2017 compared to $547 million ($244 million on pool policies with aggregate loss limits and $303 million on pool policies without aggregate loss limits) at December 31, 2016 . If claim payments associated with a specific pool reach the aggregate loss limit, the remaining IIF within the pool would be cancelled and any remaining defaults under the pool would be removed from our default inventory.

NET PREMIUMS WRITTEN AND EARNED

Comparative quarterly results

NPW increased 2% due to a decline in premium refunds and lower ceded premiums due to a higher profit commission. NPE declined marginally due to lower premiums from our IIF during the period, mostly offset by declines in ceded premiums and premium refunds when compared to the prior year.

Comparative year to date results

NPW increased 1% due to a decline in premium refunds and lower ceded premiums due to a higher profit commission, offset in part by a decrease in premiums from our IIF during the period compared to the prior year. NPE increased 1% due to declines in premium refunds and ceded premiums, offset in part by a decrease in premiums from our IIF during the period compared to the prior year.

See “Overview - Factors Affecting Our Results” above for additional factors that influenced the amount of net premiums written and earned during the period.

Premium Yield (see table 07 )

Premium yield (NPE divided by average IIF) decreased from the prior year periods to 50.1 and 49.8 basis points for Q3 and YTD 2017 , respectively, ( Q3 2016 : 53.1 basis points, YTD 2016 : 51.9 basis points) and is influenced by a number of key drivers, which have a varying impact from period to period.

The decline in our premium yield compared to the respective prior year periods reflects:


•	A larger percentage of our IIF from book years with lower premium rates due to a decline in premium rates in recent periods and a portion of our book years undergoing premium rate resets on their ten-year anniversary, as well as less of a positive impact from acceleration of premium recognition upon cancellation of single premium policies; offset in part by,


•	less of an adverse impact from premium refunds and reinsurance, each primarily due to lower claim activity.

The following table reconciles our premium yield for the three and nine months ended September 30, 2017 from the respective prior year periods.

Premium yield - September 30, 2017	50.1		49.8

Reinsurance agreements (see tables 08 and 09 )

Our reinsurance affects various lines of our statements of operations and therefore we believe it should be analyzed by reviewing its total effect on our pre-tax income, described as follows.


•	We cede a fixed percentage of premiums on insurance covered by the agreements.

•

We receive the benefit of a profit commission through a reduction in the premiums we cede. The profit commission varies directly and inversely with the level of losses on a “dollar for dollar” basis and is eliminated at levels of losses that we do not expect to occur. As a result, lower levels of losses result in a higher profit commission and less benefit from ceded losses; higher levels of losses result in more

Table of contents

benefit from ceded losses and a lower profit commission (or for levels of losses we do not expect, its elimination).


•	We receive the benefit of a ceding commission through a reduction in underwriting expenses equal to 20% of premiums ceded (before the effect of the profit commission).


•	We cede a fixed percentage of losses incurred on insurance covered by the agreements.

The effects described above result in a net cost of the reinsurance, with respect to a covered loan, of 6% (but can be lower if losses are materially higher than we expect). This cost is derived by dividing the reduction in our pre-tax net income from such loans with reinsurance by our direct (that is, without reinsurance) premiums from such loan. Although the net cost of the reinsurance is generally constant at 6%, the effect of the reinsurance on the various components of pre-tax income discussed above will vary from period to period, depending on the level of ceded losses.

The amount of our NIW subject to our QSR Transactions (see table 08 ) will vary from period to period due to loan level exclusion terms. For example, our 2017 QSR Transaction excludes NIW with amortization terms of 20 years or less, but allows higher limits on debt-to-income and loan levels than our 2015 QSR Transaction. In addition, the QSR Transactions contain coverage thresholds that may be triggered depending on the mix of our risk written during the period.

The following tables provide additional information related to our reinsurance agreements for 2017 and 2016 .

INVESTMENT INCOME

Comparative quarterly and year to date results

Net investment income in the third quarter of 2017 was $30.4 million , up from $27.5 million in the prior year period. Net investment income in the first nine months of 2017 was $89.6 million , up from $82.6 million in the prior year period. The increase in investment income in both periods was due to an increase in the average balance of the investment portfolio along with higher investment yields over the periods.

NET REALIZED INVESTMENT (LOSSES) GAINS

Comparative quarterly and year to date results

Net realized losses for the third quarter and first nine months of 2017 were immaterial to our consolidated financial statements in both periods, whereas we recorded net realized gains of $5.1 million and $9.0 million for the third quarter and first nine months of 2016 , respectively.

The net unrealized gains (losses) position of our investment portfolio) as of September 30, 2017 and December 31, 2016 is presented in the following chart ( 10 ).

OTHER REVENUE

Comparative quarterly results

Other revenue for the third quarter of 2017 was $2.9 million , down from $3.9 million in the prior year primarily due to a decline in contract underwriting fees.

Comparative year to date results

Other revenue for the first nine months of 2017 was $7.8 million , down from $14.2 million in the prior year period. Contract underwriting fees were lower in the current year and the prior year included approximately $4 million of gains recognized upon the substantial liquidation of our Australian operations resulting from changes in foreign currency exchange rates.

LOSSES INCURRED, NET

As discussed in “Critical Accounting Policies” in our 10-K MD&A and consistent with industry practices, we establish loss reserves for future claims only for loans that are currently delinquent. The terms “delinquent” and “default” are used interchangeably by us. We consider a loan in default when it is two or more payments past due. Loss reserves are established based on estimating the number of loans in our default inventory that will result in a claim payment, which is referred to as the claim rate, and further estimating the amount of the claim payment, which is referred to as claim severity.

Estimation of losses is inherently judgmental. The conditions that affect the claim rate and claim severity include the current and future state of the domestic economy, including unemployment, and the current and future strength of local housing markets. The actual amount of the claim payments may be substantially different than our loss reserve estimates. Our estimates could be adversely affected by several factors, including a deterioration of regional or national economic conditions, including unemployment, leading to a reduction in borrower income and thus their ability to make mortgage payments, and a drop in housing values that could result in, among other things, greater losses on loans, and may affect borrower willingness to continue to make mortgage payments when the value of the home is

below the mortgage balance. Historically, losses incurred have followed a seasonal trend in which the second half of the year has weaker credit performance than the first half, with higher new notice activity and a lower cure rate. Our estimates are also affected by any agreements we enter into regarding our claims paying practices, such as the settlement agreements discussed in Note 5 – “Litigation and Contingencies” to our consolidated financial statements. Changes to our estimates could result in a material impact to our consolidated results of operations and financial position, even in a stable economic environment.

Losses incurred, net (see table 11 )

Comparative quarterly results

Losses incurred, net in the third quarter of 2017 decreased 51% to $30 million compared to $61 million in the prior year. The decrease was due to a decrease in losses and LAE incurred on defaults reported in the current year. Losses incurred on current year defaults declined due to a 9% reduction in new notices received and a lower claim rate on new notices (see chart 13 ). Favorable development on prior year defaults occurred in the third quarter of 2017 and 2016 primarily due to a lower claim rate.

Comparative year to date results

Losses incurred, net in the first nine months of 2017 decreased 56% to $85 million compared to $192 million in the prior year. The decrease was due to a decrease in losses and LAE incurred on defaults reported in the current year and higher favorable development on prior year defaults. Losses incurred on current year defaults declined due to a 10% reduction in new notices received and a lower claim rate on new notices (see chart 13 ). Favorable development on prior year defaults occurred in both the 2017 and 2016 periods primarily due to a lower claim rate. The favorable development in 2016 was partially offset by an increase in our severity assumption. The increase in our severity assumption generally reflected a rising trend in our average claim paid at that time (see table 15 ).

Loss Ratio (see chart 12 )

The loss ratio is the ratio, expressed as a percentage, of the sum of incurred losses and loss adjustment expenses to net premiums earned. The decline in the loss ratio in the three and nine months ended September 30, 2017 compared to the respective prior year periods was primarily due to a lower level of losses incurred, net.



12	LOSS RATIO

New Notice Claim Rate (see chart 13 )


•	Q3 2017: ~11% compared to Q3 2016: ~12%


•	YTD 2017: ~11% compared to YTD 2016: ~13%


•	The quarterly new notice claim rate during 2017 has generally ranged from 10.5% to 11%, down from the same prior year period in which the new notice claim rate generally ranged from 12% to 13%. We expect our new notice claim rates for the remainder of 2017 to be lower than the comparable 2016 rates.


•	New notice activity continues to be primarily driven by loans insured in 2008 and prior (see chart 14 ), which continue to experience a cycle whereby many loans default, cure, and re-default. This cycle, along with the duration that defaults may ultimately remain in our notice inventory, results in significant judgment in establishing the estimated claim rate.

Table of contents

Claims Severity (see table 15 )

Factors that impact claim severity include the exposure on the loan (the unpaid principal balance of the loan times our insurance coverage percentage), the amount of time between default and claim filing (which impacts the amount of interest and expenses) and curtailments. All else being equal, the longer the period between default and claim filing, the greater the severity. As discussed in Note 12 - “Loss Reserves” , the average time servicers are utilizing to process foreclosures has shortened and therefore we expect the average number of missed payments at the time a claim is received to be approximately 18 to 24 for new notices received in future periods. In recent periods, defaults resulting in claim payments had an average of 35 missed payments at the claim received date. Our loss reserves estimates take into consideration trends over time, because the development of the delinquencies may vary from period to period without establishing a meaningful trend.

The majority of loans from 2005-2008 (which represent the majority of loans in the delinquent inventory) are covered by master policy terms that, except under certain circumstances, do not limit the number of years that an insured can include interest when filing a claim if they comply with their obligations under the terms of the master policy.

⁽¹⁾ Settlements include amounts paid in settlement disputes for claims paying practices and commutations of NPLs.

In considering the potential sensitivity of the factors underlying our estimate of loss reserves, it is possible that even a relatively small change in our estimated claim rate or severity could have a material impact on reserves and, correspondingly, on our consolidated results of operations even in a stable economic environment. For example, as of September 30, 2017 , assuming all other factors remain constant, a $1,000 increase/decrease in the average severity reserve factor would change the reserve amount by approximately +/- $20 million. A 1 percentage point increase/decrease in the average claim rate reserve factor would change the reserve amount by approximately +/- $23 million.

See Note 12 – “Loss Reserves” to our consolidated financial statements for a discussion of our losses incurred and claims paying practices (including curtailments).

Net losses and LAE paid

Net losses and LAE paid in the three and nine months ended September 30, 2017 declined 30% and 25% , respectively, compared to the same periods in the prior year due to lower claim activity on our primary and pool business and a reduction in losses paid under settlement agreements. We believe losses and LAE paid will continue to decline as the credit profile of our RIF continues to improve and our delinquent inventory declines.

The following table presents our net losses and LAE paid for the three and nine months ended September 30, 2017 and 2016 .

Hurricanes Harvey, Irma, and Maria

As discussed in Note 12 - “Loss Reserves,” recent hurricane activity primarily impacting Texas, Florida, and Puerto Rico has increased the number of new notices of default reported to us in October and we expect to continue to see elevated levels of new notice activity on loans in the impacted areas through the remainder of 2017. Based on our analysis and past experience, we expect the majority of new defaults in the hurricane affected areas to cure and to not result in a material increase in our incurred losses or losses paid. When establishing our loss reserves in the near-term, we expect to apply a lower estimated claim rate to new default notices from the affected areas than the claim rate we apply to other notices in our default inventory. See our risk factors titled “Recent hurricanes may impact our incurred losses, the amount and timing of paid claims, our inventory of notices of default and our Minimum Required Assets under PMIERs” and “Downturns in the domestic economy or declines in the value of borrowers’ homes from their value at the time their loans closed may result in more homeowners defaulting and our losses increasing, with a corresponding decrease in our returns” for factors that could cause our actual results to differ from our expectations expressed in this paragraph.

Loss reserves

Our primary default rate at September 30, 2017 was 4.07% (YE 2016: 5.04% , September 30, 2016 : 5.16% ). Our primary default inventory contained 41,235 loans at September 30, 2017 , representing a decrease of 18% from December 31, 2016 and 20% from September 30, 2016 . The reduction in our primary default inventory is the result of the total number of defaulted loans: (1) that have cured; (2) for which claim payments have been made; or (3) that have resulted in rescission, claim denial, or removal from inventory due to settlements, collectively exceeding the total number of new defaults on insured loans. In recent periods, we have experienced improved cure rates and the overall mix of our default inventory, as represented by the number of missed payments, has improved compared to the prior years. As of September 30, 2017 , the percentage of our default inventory that has 12 or more missed payments was 33% (YE 2016: 38% , September 30, 2016 : 40% ). Generally, a defaulted loan with fewer missed payments is less likely to result in a claim. We expect our default inventory to continue to decline; however, the pace of decline will be impacted by the rate our recent books naturally season, commutations of NPL’s, settlement agreements, and the recent hurricane activity discussed above.

The gross reserves at September 30, 2017 , December 31, 2016 and September 30, 2016 appear in the table below.

Our results of operations continue to be negatively impacted by the mortgage insurance we wrote during 2005 through 2008 (see chart 16 ). Although uncertainty remains with respect to the ultimate losses we may experience on those books of business, as we continue to write new insurance on high-quality mortgages, those books have become a smaller percentage of our total portfolio, and we expect this trend to continue. Our 2005 through 2008 books of business represented approximately 21% and 25% of our total primary RIF at September 30, 2017 and December 31, 2016 , respectively. Approximately 39% and 38% of the remaining primary RIF on our 2005 through 2008 books of business benefited from HARP as of September 30, 2017 and December 31, 2016 , respectively.



16	DEFAULT INVENTORY MIX BY BOOK YEAR % OF TOTAL INVENTORY

On our primary business, the highest claim frequency years have typically been the third and fourth year after the year of loan origination. However, the pattern of claim frequency can be affected by many factors, including persistency and deteriorating economic conditions. Low persistency can accelerate the period in the life of a book during which the highest claim frequency occurs. Deteriorating economic conditions can result in increasing claims following a period of declining claims. As of September 30, 2017 , 55% of our primary RIF was written subsequent to December 31, 2014, 64% of our primary RIF was written subsequent to December 31, 2013, and 70% of our primary RIF was written subsequent to December 31, 2012.

UNDERWRITING AND OTHER EXPENSES, NET

Comparative quarterly and year to date results

Underwriting and other expenses includes items such as employee compensation costs, fees for professional services, depreciation and maintenance expense, and premium taxes, and are reported net of ceding commissions.

Underwriting and other expenses, net for the three and nine months ended September 30, 2017 were $39.9 million and $119.2 million , respectively, up from $37.9 million and $113.0 million in the respective prior year periods. The increases

MGIC Investment Corporation - Q3 2017 | 48

were primarily due to higher depreciation and compensation expenses.

Underwriting expense ratio ( see chart 17 ) . The underwriting expense ratio is the ratio, expressed as a percentage, of the underwriting and operating expenses, net and amortization of DAC of our combined insurance operations (which excludes underwriting and operating expenses of our non-insurance operations) to NPW. The underwriting expense ratio in the each of the three and nine months ended September 30, 2017 increased compared to the respective prior year periods. The increase in the ratio in both periods was primarily due to higher depreciation and compensation expenses in the current year periods; offset in part by increases in NPW in both periods.



17	UNDERWRITING EXPENSE RATIO

INTEREST EXPENSE

Comparative quarterly and year to date results

Interest expense for the three months ended September 30, 2017 was $13.3 million , down from $13.5 million in the prior year period. Interest expense for the nine months ended September 30, 2017 was $43.8 million up from $40.5 million in the same period of the prior year due to interest expense incurred on our 5.75% Notes and revolving credit facility, which offset the reduction in interest expense from the maturity of our 5% Notes and elimination of our 2% Notes through conversion and partial redemption during the period.

See Note 3 - “Debt” for debt transaction activity impacting the comparability of our interest expense in 2017 relative to 2016.

LOSS ON DEBT EXTINGUISHMENT

Comparative quarterly and year to date results

Loss on debt extinguishment of $75.2 million for the three months ended September 30, 2016 reflects the repurchase of a portion of our 2% Notes at amounts above our carrying value. Loss on debt extinguishment of $90.5 million for the nine months ended September 30, 2016 primarily reflects the repurchase of our 2% Notes at an amount in excess of our carrying value in the third quarter. The amount also includes the repurchase of a portion of our 5% Notes at an amount in excess of our carrying value, and MGIC’s purchase of a portion of our 9% Debentures with the loss representing the difference between the fair value and carrying value of the liability component on the purchase date. These transactions repositioned the maturity profile of our debt and reduced potentially dilutive shares at the time of their execution.

The difference between our statutory tax rate of 35% and our effective tax rate of 34.9% and 32.4% for the respective three months ended September 30, 2017 and 2016 was primarily due to the benefits of tax preferenced securities. The difference between our statutory rate of 35% and our effective tax rate of 39.1% for the nine months ended September 30, 2017 is due to the $28.4 million additional provision recorded for the expected settlement of our IRS litigation more than offsetting benefits of tax preferenced securities. The difference between our statutory tax rate of 35% and our effective tax rate of 33.3% for the nine months ended September 30, 2016 was primarily due to the benefits of tax preferenced securities.

Balance Sheet Review

Total assets and total liabilities

As of September 30, 2017 , total assets were $5.7 billion and total liabilities were $2.5 billion . Compared to year-end 2016 , this represented a decrease of $58.7 million in total assets and of $640.0 million in total liabilities.

The following sections mainly focus on our cash and cash equivalents and deferred income taxes, net, as these reflect the major developments in our assets and loss reserves and debt as these reflect the major developments in our liabilities since December 31, 2016 .

ASSETS

Cash and cash equivalents - Our cash and cash equivalents balance increased as net cash generated from operating activities was only partly offset by net cash used in investing and financing activities.

Deferred income taxes, net - The decrease in our deferred income taxes, net was primarily due to the utilization of federal net operating loss carryforwards as we generated net income during the first nine months of 2017.

As of September 30, 2017 , our deferred tax asset was $416.2 million . A decrease in the federal statutory rate will result in a one-time reduction in the amount at which our deferred tax asset is recorded, thereby reducing our net income and book value; however, such a decrease will also reduce our effective tax rate in future periods, thereby increasing net income. We estimate that every 1 percentage point reduction in the federal statutory rate would result in a one-time reduction in our deferred tax asset of $11.5 million.

Investment portfolio

The average duration and imbedded pre-tax investment yield of our investment portfolio as of September 30, 2017 , December 31, 2016 , and September 30, 2016 is presented in the following table.

We increased our investment portfolio fixed income asset allocation of “A” rated securities since December 31, 2016 (see table 19 ). As of September 30, 2017 , the amount of invested assets (as measured by amortized cost) is lower

compared to December 31, 2016 , however the total fair value is 1% higher.

⁽¹⁾	Ratings are provided by one or more of: Moody's, Standard & Poor's and Fitch Ratings. If three ratings are available, the middle rating is utilized; otherwise the lowest rating is utilized.

LIABILITIES

Loss reserves - Our loss reserves can be split into two parts: (1) reserves representing estimates of losses and settlement expenses on known delinquencies and (2) IBNR. Our gross liability for both is reduced by reinsurance recoverable on our estimated losses and settlement expenses to calculate a net reserve balance. The net reserve balance decreased by 24% to $1.06 billion as of September 30, 2017 , from $1.39 billion as of December 31, 2016 . Reinsurance recoverable on our estimated losses and settlement expenses were $45.9 million and $50.5 million as of September 30, 2017 and December 31, 2016 , respectively. The overall decrease in our loss reserves during the first nine months of 2017 was due to a higher level of losses paid ( $413.8 million ) relative to losses incurred ( $84.7 million ).

Debt - The decrease in our consolidated debt was due to the elimination of our 2% Notes in April through a combination of conversions and cash redemptions and repayment of our 5% Notes on May 1, 2017 with holding company cash. See Note 3 - “Debt” for further information on our 2017 debt transactions and remaining outstanding obligations.

Total shareholders’ equity

As of September 30, 2017 , total shareholders’ equity amounted to $3.1 billion , an increase of $581.3 million compared to December 31, 2016 . The increase in our total shareholders’ equity was due to net income in the first nine months of 2017, issuance of common stock to holders of our 2% Notes that elected to convert their notes during the second quarter, and an increase in the fair value of our investment portfolio during the first nine months of 2017.

As described in Note 3 - “Debt” , approximately $202.5 million of principal outstanding on our 2% Notes was converted to shares of common stock in April which resulted in an increase to our shareholders’ equity for the carrying value of the notes at the time of conversion.

Liquidity and Capital Resources

Consolidated Cash Flow Analysis

We have three primary types of cash flows: (1) operating cash flows, which consist mainly of cash generated by our insurance operations and income earned on our investment portfolio, less amounts paid for claims, interest expense and operating expenses, (2) investing cash flows related to the purchase, sale and maturity of investments and purchases of property and equipment and (3) financing cash flows generally from activities that impact our capital structure, such as changes in debt and shares outstanding. The following table summarizes our consolidated cash flows from operating, investing and financing activities:



	Nine Months Ended September 30,
(In thousands)	2017			2016
Total cash provided by (used in):
Operating activities	256,356			148,986
Investing activities	(2,529		)	45,973
Financing activities	(158,536		)	(101,336		)
Increase in cash and cash equivalents	$	95,291		$	93,623

Net cash provided by operating activities for the nine months ended September 30, 2017 increased compared to the same period of 2016 primarily due to a lower level of losses paid, net, offset in part by increases in payments for interest and other expenses.

Net cash from investing activities for the nine months ended September 30, 2017 decreased when compared to the same period of 2016, primarily due to an increase in the percentage of proceeds from the maturity and sales of fixed income securities that were reinvested, and an increase in amounts invested in property and equipment.

Net cash used in financing activities for the nine months ended September 30, 2017 included the repayment at maturity of our 5% Notes and redemption of a portion of our 2% Notes, as well as, expenses paid to establish the revolving credit facility and cash remittance of withholding taxes paid by employees through shares withheld upon vesting of restricted stock units.

Net cash used in financing activities for the nine months ended September 30, 2016 includes the net proceeds from the issuance of our 5.75% Notes and the Advance from the FHLB, less amounts paid to purchase portions of our outstanding 5% and 2% Notes, and our 9% Debentures, and to repurchase common stock issued as partial consideration of our 2% Notes repurchases. Cash used in financing activities also included expenses associated with our 5.75% Notes issuance and cash remittance of withholding taxes paid by employees through shares withheld upon vesting of restricted stock units.

DEBT AT OUR HOLDING COMPANY AND HOLDING COMPANY LIQUIDITY

Debt - holding company (see charts 20 and 21 )

The 5.75% Notes and 9% Debentures are obligations of our holding company, MGIC Investment Corporation, and not of its subsidiaries. As of September 30, 2017 , our holding company’s debt obligations were $814.5 million in aggregate principal. In April 2017, prior to the redemption date of the 2% Notes, holders of approximately $202.5 million of the outstanding principal exercised their rights to convert their notes into shares of our common stock and we repaid the outstanding amount borrowed under our credit facility plus interest incurred. The remaining $5.1 million of our 2% Notes that did not convert were redeemed with holding company cash. The conversion of our 2% Notes into shares of our common stock, along with the cash redemption, eliminated our debt obligation. Our 5% Notes matured on May 1, 2017 and we repaid the $145 million of outstanding principal with holding company cash.

These resources are maintained primarily to service our debt interest expense, pay debt maturities, repurchase outstanding debt obligations from time to time, and to settle intercompany obligations. We may also use available holding company cash to repurchase shares of our common stock. While these assets are held, we generate investment income that serves to offset a portion of our interest expense. In addition to investment income, the payment of dividends from our insurance subsidiaries and/or raising capital in the public markets are the principal sources of holding company cash inflow. MGIC is the principal source of dividend-paying capacity, which is restricted by insurance regulation. The ability to raise capital in the public markets is subject to prevailing market conditions, investor demand for the securities to be issued, and our deemed creditworthiness.

In the third quarter of 2017, our holding company cash and investments increased by $33 million , to $182 million as of September 30, 2017 . Cash inflows during the quarter included $40 million of dividends received from MGIC and other inflows of $5 million. Cash outflows during the quarter at our holding company included $12 million of interest payments on our 5.75% Notes. We expect MGIC to continue to pay quarterly dividends. We ask the OCI not to object before MGIC pays dividends.

The net unrealized losses on our holding company investment portfolio were approximately $1 million at September 30, 2017 and the portfolio had a modified duration of approximately 2.6 years.

We may from time to time continue to seek to acquire our debt obligations through cash purchases and/or exchanges for other securities. We may also from time to time seek to acquire our common stock through cash purchases,

including with funds provided by debt. We may make such acquisitions in open market purchases, privately negotiated acquisitions or other transactions. The amounts involved may be material.

Subject to certain limitations and restrictions, holders of each of the 9% Debentures may convert their notes into shares of our common stock at their option prior to certain dates under the terms of their issuance, in which case our corresponding obligation will be eliminated.

See Note 7 – “Debt” to our consolidated financial statements in our Annual Report on Form 10-K for the year ended December 31, 2016 for additional information about our convertible debt, including our conditional right to redeem, and our option to defer interest on, our 9% Debentures. Any deferred interest compounds at the stated rate of 9%. The description in Note 7 - “Debt” to our consolidated financial statements in our Annual Report on Form 10-K is qualified in its entirety by the terms of the notes and debentures.

Although not anticipated in the near term, we may also contribute funds to our insurance operations to comply with the PMIERs or the State Capital Requirements. See “Overview - Capital” above for a discussion of these requirements. See discussion of our non-insurance contract underwriting services in Note 5 – “Litigation and Contingencies” to our consolidated financial statements.

DEBT AT SUBSIDIARIES

MGIC is a member of the FHLB, which provides MGIC access to an additional source of liquidity via a secured lending facility. MGIC has $155.0 million of debt outstanding in the form of a fixed rate advance from the FHLB. Interest on the Advance is payable monthly at an annual rate, fixed for the term of the Advance, of 1.91%. The principal of the Advance matures on February 10, 2023. MGIC may prepay the Advance at any time. Such prepayment would be below par if interest rates have risen after the Advance was originated, or above par if interest rates have declined. The Advance is secured by eligible collateral whose fair value must be maintained at 102% of the outstanding principal balance. MGIC provided eligible collateral from its investment portfolio.

Capital Adequacy

PMIERs

We operate under the PMIERs of the GSEs that became effective December 31, 2015. The revisions to the PMIERS since then have had no impact on our calculation of Available Assets or Minimum Required Assets, or our operations. The GSEs may further amend the PMIERs at any time, and they have broad discretion to interpret the requirements, which could impact the calculation of our Available Assets and/or Minimum Required Assets. The PMIERS provide that the factors that determine Minimum Required Assets will be updated every two years and may be updated more frequently to reflect changes in macroeconomic conditions or loan performance. The GSEs have informed us that they currently

MGIC Investment Corporation - Q3 2017 | 52

Table of contents

do not expect any updates to such factors to be effective before the fourth quarter of 2018 and we expect the GSEs will provide notice 180 days prior to the effective date of such updates.

As of September 30, 2017 , MGIC’s Available Assets under PMIERs totaled $4.7 billion , an excess of $0.8 billion over its Minimum Required Assets; and MGIC is in compliance with the requirements of the PMIERs and eligible to insure loans purchased by the GSEs. Beginning in October 2017, we have begun to receive an increased number of new default notices related to loans in locations that FEMA has declared IADAs in connection with recent hurricane activity primarily impacting Texas, Florida, and Puerto Rico. As a result, our excess Available Assets may decline as the PMIERS require us to maintain significantly more Minimum Required Assets for delinquent loans than for performing loans. Our excess Available Assets allow MGIC to remain in compliance with the PMIERs financial requirements, including, we believe, to the extent they are modified further in the next review; and will also allow us flexibility to participate in additional business opportunities as they may arise. Our QSR Transactions provided an aggregate of $0.8 billion of PMIERs capital credit as of September 30, 2017 .

We plan to continuously comply with the PMIERs through our operational activities or through the contribution of funds from our holding company, subject to demands on the holding company's resources, as outlined above.

RISK-TO-CAPITAL

We compute our risk-to-capital ratio on a separate company statutory basis, as well as on a combined insurance operation basis. The risk-to-capital ratio is our net RIF divided by our policyholders’ position. Our net RIF includes both primary and pool risk in force, and excludes risk on policies that are currently in default and for which loss reserves have been established, and those covered by reinsurance. The risk amount includes pools of loans with contractual aggregate loss limits and without these limits. Policyholders’ position consists primarily of statutory policyholders’ surplus (which increases as a result of statutory net income and decreases as a result of statutory net loss and dividends paid), plus the statutory contingency reserve, and a portion of the reserves for unearned premiums. The statutory contingency reserve is reported as a liability on the statutory balance sheet. A mortgage insurance company is required to make annual additions to the contingency reserve of approximately 50% of net earned premiums. These contributions must generally be maintained for a period of ten years. However, with regulatory approval a mortgage insurance company may make early withdrawals from the contingency reserve when incurred losses exceed 35% of net earned premiums in a calendar year.

MGIC’s separate company risk-to-capital calculation appears in the table below.



(In millions, except ratio)	September 30, 2017		December 31, 2016
RIF - net ⁽¹⁾	$	30,561	$	28,668
Statutory policyholders’ surplus	1,501		1,505
Statutory contingency reserve	1,533		1,181
Statutory policyholders’ position	$	3,034	$	2,686
Risk-to-capital	10.1:1		10.7:1


⁽¹⁾	RIF – net, as shown in the table above is net of reinsurance and exposure on policies currently in default for which loss reserves have been established.

Our combined insurance companies’ risk-to-capital calculation appears in the table below.



(In millions, except ratio)	September 30, 2017		December 31, 2016
RIF - net ⁽¹⁾	$	36,243	$	34,465
Statutory policyholders’ surplus	1,503		1,507
Statutory contingency reserve	1,760		1,360
Statutory policyholders’ position	$	3,263	$	2,867
Risk-to-capital	11.1:1		12.0:1


⁽¹⁾	RIF – net, as shown in the table above, is net of reinsurance and exposure on policies currently in default ($2.1 billion at September 30, 2017 and $2.6 billion at December 31, 2016 ) for which loss reserves have been established.

The reductions in MGIC's and our combined insurance companies’ risk-to-capital in the first nine months of 2017 were primarily due to an increase in statutory policyholders’ position due to an increase in statutory contingency reserves, partially offset by an increase in net RIF in both calculations. Our RIF, net of reinsurance, increased in the first nine months of 2017 , due to an increase in our IIF. Our risk-to-capital ratio will decrease if the percentage increase in capital exceeds the percentage increase in insured risk.

For additional information regarding regulatory capital see Note 15 – “Statutory Information” to our consolidated financial statements as well as our risk factor titled “State Capital requirements may prevent us from continuing to write new insurance on an uninterrupted basis.”

Total	$	3,530.8	$	656.8	$	661.8	$	247.0	$	1,965.2

Our long-term debt obligations as of September 30, 2017 include their related interest and are discussed in Note 3 - “Debt” to our consolidated financial statements and under “Liquidity and Capital Resources” above. Our operating lease obligations include operating leases on certain office space, data processing equipment and autos, as discussed in Note 16 – “Leases” to our consolidated financial statements in our Annual Report on Form 10-K for the year ended December 31, 2016. Tax obligations primarily relate to our current dispute with the IRS, as discussed in Note 11 – “Income Taxes.” Purchase obligations consist primarily of agreements to purchase items related to our ongoing infrastructure projects and information technology investments in the normal course of business. See Note 11 – “Benefit Plans” to our consolidated financial statements in our Annual Report on Form 10-K for the year ended December 31, 2016 for a discussion of expected benefit payments under our benefit plans.

Our other long-term liabilities represent the loss reserves established to recognize the liability for losses and LAE related to existing defaults on insured mortgage loans. The timing of the future claim payments associated with the established loss reserves was determined primarily based on two key assumptions: the length of time it takes for a notice of default to develop into a received claim and the length of time it takes for a received claim to be ultimately paid. The future claim payment periods are estimated based on historical experience, and could emerge significantly different than this estimate, in part, due to the uncertainty regarding how certain factors, such as loss mitigation protocols established by servicers and changes in some state foreclosure laws that may include, for example, a requirement for additional review and/or mediation process, which will continue to affect our future paid claims. See Note 12 – “Loss Reserves” to our consolidated financial statements. In accordance with GAAP for the mortgage insurance industry, we establish loss reserves only for loans in default. Because our reserving method does not take account of the impact of future losses that could occur from loans that are not delinquent, our obligation for ultimate losses that we expect to occur under our policies in force at any period end is not reflected in our consolidated financial statements or in the table above.

Forward Looking Statements and Risk Factors

General : Our business, results of operations, and financial condition could be affected by the risk factors referred to under “Location of Risk Factors” below. These risk factors are an integral part of Management’s Discussion and Analysis.

These factors may also cause actual results to differ materially from the results contemplated by forward looking statements that we may make. Forward looking statements consist of statements which relate to matters other than historical fact. Among others, statements that include words such as we “believe,” “anticipate” or “expect,” or words of similar import, are forward looking statements. We are not undertaking any obligation to update any forward looking statements we may make even though these statements may be affected by events or circumstances occurring after the forward looking statements were made. Therefore no reader of this document should rely on these statements being current as of any time other than the time at which this document was filed with the Securities and Exchange Commission.

While we communicate with security analysts from time to time, it is against our policy to disclose to them any material non-public information or other confidential information. Accordingly, investors should not assume that we agree with any statement or report issued by any analyst irrespective of the content of the statement or report, and such reports are not our responsibility.

Location of Risk Factors: The risk factors are in Item 1 A of our Annual Report on Form 10-K for the year ended December 31, 2016, as supplemented by Part II, Item 1 A of our Quarterly Reports on Form 10-Q for the Quarters ended March 31, 2017 and June 30, 2017, and by Part II, Item 1 A of this Quarterly Report on Form 10-Q. The risk factors in the 10-K, as supplemented by these 10‑Qs and through updating of various statistical and other information, are reproduced in Exhibit 99 to this Quarterly Report on Form 10-Q.

Item 3. Quantitative and Qualitative Disclosures about Market Risk

Our investment portfolio is essentially a fixed income portfolio and is exposed to market risk. Important drivers of the market risk are credit spread risk and interest rate risk.

Credit spread risk is the risk that we will incur a loss due to adverse changes in credit spreads. Credit spread is the additional yield on fixed income securities above the risk-free rate (typically referenced as the yield on U.S. Treasury securities) that market participants require to compensate them for assuming credit, liquidity and/or prepayment risks.

We manage credit risk via our investment policy guidelines which primarily place our investments in investment grade securities and limit the amount of our credit exposure to any one issue, issuer and type of instrument. Guideline and investment portfolio detail is available in "Business – Section C, Investment Portfolio" in Item 1 of our Annual Report on Form 10-K for the year ended December 31, 2016.

Interest rate risk is the risk that we will incur a loss due to adverse changes in interest rates relative to the characteristics of our interest bearing assets.

One of the measures used to quantify this exposure is modified duration. Modified duration measures the price sensitivity of the assets to the changes in spreads. At September 30, 2017 , the modified duration of our fixed income investment portfolio was 4.5 years, which means that an instantaneous parallel shift in the yield curve of 100 basis points would result in a change of 4.5% in the fair value of our fixed income portfolio. For an upward shift in the yield curve, the fair value of our portfolio would decrease and for a downward shift in the yield curve, the fair value would increase. See Note 7 – “Investments ” to our consolidated financial statements for additional disclosure surrounding our investment portfolio.

Item 4. Controls and Procedures

Our management, with the participation of our principal executive officer and principal financial officer, has evaluated our disclosure controls and procedures (as defined in Rule 13a-15(e) under the Securities Exchange Act of 1934, as amended), as of the end of the period covered by this Quarterly Report on Form 10-Q. Based on such evaluation, our principal executive officer and principal financial officer concluded that such controls and procedures were effective as of the end of such period. There was no change in our internal control over financial reporting that occurred during the third quarter of 2017 that materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

PART II. OTHER INFORMATION

Item 1. Legal Proceedings

While we do not view the following as a material development, the parties in our previously disclosed U.S. Tax Court case with the Internal Revenue Service informed the Court in August 2017 that they had reached agreement in principle on all issues in the case and were preparing the documentation reflecting the terms of their agreement. The agreed settlement terms will be subject to review by the Joint Committee on Taxation (“JCT”) before a settlement can be completed and there is no assurance that a settlement will be completed.

Item 1 A. Risk Factors

With the exception of the changes described and set forth below, there have been no material changes in our risk factors from the risk factors disclosed in the Company’s Annual Report on Form 10-K for the year ended December 31, 2016, as supplemented by Part II, Item I A of our Quarterly Report on Form 10-Q for the Quarters ended March 31, 2017 and June 30, 2017. The risk factors in the 10-K, as supplemented by those 10-Qs and this 10-Q, and through updating of various statistical and other information, are reproduced in their entirety in Exhibit 99 to this Quarterly Report on Form 10-Q.

Resolution of our dispute with the Internal Revenue Service could adversely affect us.

The Internal Revenue Service (“IRS”) completed examinations of our federal income tax returns for the years 2000 through 2007 and issued proposed assessments for taxes, interest and penalties related to our treatment of the flow-through income and loss from an investment in a portfolio of residual interests of Real Estate Mortgage Investment Conduits (“REMICs”). The IRS indicated that it did not believe that, for various reasons, we had established sufficient tax basis in the REMIC residual interests to deduct the losses from taxable income. We appealed these assessments within the IRS and in August 2010, we reached a tentative settlement agreement with the IRS which was not finalized.

precaution to keep open the statute of limitations on collection of the tax that was refunded when this loss was carried back, and not because the IRS actually intends to disallow the carryback permanently. Depending on the outcome of this matter, additional state income taxes and state interest may become due when a final resolution is reached. As of September 30, 2017, those state taxes and interest would approximate $84.1 million . In addition, there could also be state tax penalties. Our total amount of unrecognized tax benefits as of September 30, 2017 is $141.8 million , which represents the tax benefits generated by the REMIC portfolio included in our tax returns that we have not taken benefit for in our financial statements, including any related interest.

We filed a petition with the U.S. Tax Court contesting most of the IRS’ proposed adjustments reflected in the Notices of Deficiency and the IRS filed an answer to our petition which continued to assert their claim. The case has twice been scheduled for trial and in each instance, the parties jointly filed, and the U.S. Tax Court approved (most recently in February 2016), motions for continuance to postpone the trial date. Also in February 2016, the U.S. Tax Court approved a joint motion to consolidate for trial, briefing, and opinion, our case with similar cases of Radian Group, Inc., as successor to Enhance Financial Services Group, Inc., et al. The parties informed the Tax Court in August 2017 that they had reached agreement in principle on all issues in the case and were preparing the documentation reflecting the terms of their agreement. The agreed settlement terms will be subject to review by the Joint Committee on Taxation (“JCT”) before a settlement can be completed and there is no assurance that a settlement will be completed. Based on information that we currently have regarding the status of our ongoing dispute, we recorded a provision for additional taxes and interest of $28.4 million in 2017.

Should a settlement not be completed, ongoing litigation to resolve our dispute with the IRS could be lengthy and costly in terms of legal fees and related expenses. We would need to make further adjustments, which could be material, to our tax provision and liabilities if our view of the probability of success in this matter changes, and the ultimate resolution of this matter could have a material negative impact on our effective tax rate, results of operations, cash flows, available assets and statutory capital. In this regard, see our risk factors titled “We may not continue to meet the GSEs’ private mortgage insurer eligibility requirements and our returns may decrease as we are required to maintain more capital in order to maintain our eligibility” and “State capital requirements may prevent us from continuing to write new insurance on an uninterrupted basis.”

Recent hurricanes may impact our incurred losses, the amount and timing of paid claims, our inventory of notices of default and our Minimum Required Assets under PMIERs.

We expect an increase in the number of borrowers missing their mortgage payments in the areas affected by recent hurricanes in Texas, Florida and Puerto Rico. Despite the associated increase in our inventory of notices of default, based on our analysis and past experience, we do not expect the recent hurricane activity to result in a material increase in our incurred losses or paid claims. However, the following factors could cause our actual results to differ from our expectation in the forward looking statement in the preceding sentence:


•	Third party reports that indicate the extent of flooding in the hurricane-affected areas may be understated.


•	Home values in hurricane-affected areas may decrease at the time claims are filed from their current levels thereby adversely affecting our ability to mitigate loss.


•	Hurricane-affected areas may experience deteriorating economic conditions resulting in more borrowers defaulting on their loans in the future (or failing to cure existing defaults) than we currently expect.


•	If an insured contests our claim denial or curtailment, there can be no assurance we will prevail. We describe how claims under our policy are affected by damage to the borrower’s home in our Current Report on Form 8-K filed with the SEC on September 14, 2017.

Due to the suspension of certain foreclosures by the GSEs, our receipt of claims associated with foreclosed mortgages in the hurricane-affected areas may be delayed.

The PMIERs require us to maintain significantly more "Minimum Required Assets" for delinquent loans than for performing loans. An increase in default notices may result in an increase in "Minimum Required Assets" and a decrease in the level of our excess "Available Assets" which is discussed in our risk factor titled "We may not continue to meet the GSEs’ private mortgage insurer eligibility requirements and our returns may decrease as we are required to maintain more capital in order to maintain our eligibility ."
