MGIC INVESTMENT CORPORATION AND SUBSIDIARIES
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
March 31, 2004
(Unaudited)

Note 1 — Basis of presentation and summary of certain significant accounting policies

          The accompanying unaudited consolidated financial statements of MGIC Investment Corporation (the “Company”) and its wholly-owned subsidiaries have been prepared in accordance with the instructions to Form 10-Q and do not include all of the other information and disclosures required by accounting principles generally accepted in the United States of America. These statements should be read in conjunction with the consolidated financial statements and notes thereto for the year ended December 31, 2003 included in the Company’s Annual Report on Form 10-K for that year.

          The accompanying consolidated financial statements have not been audited by independent accountants in accordance with generally accepted auditing standards, but in the opinion of management such financial statements include all adjustments, including normal recurring accruals, necessary to summarize fairly the Company’s financial position and results of operations. The results of operations for the three months ended March 31, 2004 may not be indicative of the results that may be expected for the year ending December 31, 2004.

     Deferred insurance policy acquisition costs

          Costs associated with the acquisition of mortgage insurance business, consisting of employee compensation and other policy issuance and underwriting expenses, are initially deferred and reported as deferred insurance policy acquisition costs (“DAC”). Because Statement of Financial Accounting Standards (“SFAS”) No. 60, Accounting and Reporting by Insurance Enterprises, specifically excludes mortgage guaranty insurance from its guidance relating to the amortization of DAC, amortization of these costs for each underwriting year book of business is charged against revenue in proportion to estimated gross profits over the estimated life of the policies using the guidance of SFAS No. 97, Accounting and Reporting by Insurance Enterprises For Certain Long Duration Contracts and Realized Gains and Losses From the Sale of Investments. This includes accruing interest on the unamortized balance of DAC. The estimates for each underwriting year are reviewed quarterly and updated when necessary to reflect actual experience and any changes to key assumptions such as persistency or loss development.

          The Company amortized $5.5 million and $8.1 million of deferred insurance policy acquisition costs during the three months ended March 31, 2004 and 2003, respectively.

Page 5

     Loss reserves

          Reserves are established for reported insurance losses and loss adjustment expenses based on when notices of default on insured mortgage loans are received. Reserves are also established for estimated losses incurred on notices of default not yet reported by the lender. Consistent with industry practices, the Company does not establish loss reserves for future claims on insured loans which are not currently in default. Reserves are established by management using estimated claims rates and claims amounts on reported notices of default to estimate the loss. Amounts for salvage recoverable are considered in the determination of the reserve estimates. Adjustments to reserve estimates are reflected in the financial statements in the years in which the adjustments are made. The liability for reinsurance assumed is based on information provided by the ceding companies.

          The incurred but not reported (“IBNR”) reserves result from defaults occurring prior to the close of an accounting period, but which have not been reported to the Company. Consistent with reserves for reported defaults, IBNR reserves are established using estimated claims rates and claims amounts for the estimated number of defaults not reported.

          Reserves also provide for the estimated costs of settling claims, including legal and other expenses and general expenses of administering the claims settlement process.

     Revenue recognition

          The insurance subsidiaries write policies which are guaranteed renewable contracts at the insured’s option on a single, annual or monthly premium basis. The insurance subsidiaries have no ability to reunderwrite or reprice these contracts. Premiums written on a single premium basis and an annual premium basis are initially deferred as unearned premium reserve and earned over the policy term. Premiums written on policies covering more than one year are amortized over the policy life in accordance with the expiration of risk, which is the anticipated claim payment pattern based on historical experience. Premiums written on annual policies are earned on a monthly pro rata basis. Premiums written on monthly policies are earned as coverage is provided.

          Fee income of the non-insurance subsidiaries is earned and recognized as the services are provided and the customer is obligated to pay.

Stock-based compensation

          The Company has certain stock-based compensation plans. Effective January 1, 2003, the Company adopted the fair value recognition provisions of SFAS No. 123, Accounting for Stock-Based Compensation, prospectively to all employee awards granted or modified on or after January 1, 2003. The adoption of SFAS No. 123 did not have a material effect on the Company’s results of operations or its financial position. 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 the Company’s plans generally vest over periods ranging from one to five years. The cost related to stock-based employee compensation included in the determination of net income for 2004 and 2003 is less than that which

Page 6

would have been recognized if the fair value based method had been applied to all awards since the original effective date of SFAS No. 123. The following table illustrates the effect on net income and earnings per share if the fair value method had been applied to all outstanding and unvested awards in each period.

Note 2 — Short- and long-term debt

          The Company has a $285 million commercial paper program, which is rated “A-1” by Standard and Poors (“S&P”) and “P-1” by Moody’s. At March 31, 2004 and 2003, the Company had $100.4 million and $113.4 million in commercial paper outstanding with a weighted average interest rate of 1.10% and 1.33%, respectively.

          The Company has a $285 million credit facility available at March 31, 2004, expiring in 2006. Under the terms of the credit facility, the Company must maintain shareholders’ equity of at least $2.25 billion and Mortgage Guaranty Insurance Corporation (“MGIC”) must maintain a risk-to-capital ratio of not more than 22:1 and maintain policyholders’ position (which includes MGIC’s statutory surplus and its contingency reserve) of not less than the amount required by Wisconsin insurance regulation. At March 31, 2004, the Company met these requirements. The facility is currently being used as a liquidity back up facility for the outstanding commercial paper. The remaining credit available under the facility after reduction for the amount necessary to support the commercial paper was $184.6 million at March 31, 2004.

Page 7

          The Company had $300 million, 7.5% Senior Notes due in 2005 and $200 million, 6% Senior Notes due in 2007 outstanding at March 31, 2004 and 2003. At March 31, 2004 and 2003, the market value of the outstanding debt was $641.7 million and $664.5 million, respectively.

          Interest payments on all long-term and short-term debt were $7.7 million and $8.2 million for the three months ended March 31, 2004 and 2003, respectively.

          In May 2002, a swap designated as a cash flow hedge was amended to coincide with the credit facility. Under the terms of the swap contract, the Company pays a fixed rate of 5.43% and receives an interest rate based on LIBOR. The swap has an expiration date coinciding with the maturity of the credit facility and is designated as a cash flow hedge. The cash flow swap outstanding at March 31, 2004 and 2003 is evaluated quarterly using regression analysis with any ineffectiveness being recorded as an expense. To date this evaluation has not resulted in any hedge ineffectiveness. Swaps are subject to credit risk to the extent the counterparty would be unable to discharge its obligations under the swap agreements.

          Amortization expense on the interest rate swaps for the three months ended March 31, 2004 and 2003 of approximately $0.9 million and $0.6 million, respectively, was included in interest expense. Gains or losses arising from the amendment or termination of previously held interest rate swaps are deferred and amortized to interest expense over the life of the hedged items.

Note 3 — Reinsurance

          The Company cedes a portion of its business to reinsurers and records assets for reinsurance recoverable on estimated reserves for unpaid losses and unearned premiums. Business written between 1985 and 1993 is ceded under various quota share reinsurance agreements with several reinsurers. The Company receives a ceding commission in connection with this reinsurance. The Company also cedes business to reinsurance subsidiaries of certain mortgage lenders, primarily under excess of loss agreements. The majority of ceded premiums relates to these agreements.

          The reinsurance recoverable on loss reserves and the prepaid reinsurance premiums primarily represent amounts recoverable from large international reinsurers. The Company monitors the financial strength of its reinsurers including their claims paying ability rating and does not currently anticipate any collection problems. Generally, reinsurance recoverables on loss reserves and prepaid reinsurance premiums are backed by trust funds or letters of credit. No reinsurer represents more than $10 million of the aggregate amount recoverable.

Note 4 — Litigation and contingencies

          The Company is involved in litigation in the ordinary course of business. In the opinion of management, the ultimate resolution of this pending litigation will not have a material adverse effect on the financial position or results of operations of the Company.

          In addition, in March 2003 an action against MGIC was filed in Federal District Court in Orlando, Florida seeking certification of a nationwide class of consumers who were required to pay for private mortgage insurance written by MGIC and whose loans were insured at less than MGIC’s “best available rate” based on credit scores obtained by MGIC. (A portion of MGIC’s A minus premium rates are based in part on the credit score of the borrower.) The action alleges that the Federal Fair Credit Reporting Act (“FCRA”) requires a notice to borrowers of such “adverse action” and that MGIC has violated FCRA by failing to give such notice. The action seeks statutory damages (which in the case of willful violations, in addition to punitive damages, may be awarded in an amount of $100 to $1,000 per class member) and/or actual damages of the persons in the class, and attorneys fees, as well as declaratory and injunctive relief. The action also alleges that the failure to give notice to borrowers in Florida in the circumstances alleged is a violation of Florida’s Unfair and Deceptive Acts and Practices Act and seeks declaratory and injunctive relief for such violation. In December 2003, the Court denied MGIC’s motion seeking dismissal of the portion of the case covering damages under FCRA but dismissed the remainder of the case. There can be no assurance that the outcome of the litigation will not materially affect the Company’s financial position or results of operations. Similar actions have been filed against six other mortgage insurers.

          Under its contract underwriting agreements, the Company may be required to provide certain remedies to its customers if certain standards relating to the quality of the Company’s underwriting work are not met. The cost of remedies provided by the Company to customers for failing to meet these standards has not been material to the

Page 9

Company’s financial position or results of operations for three months ended March 31, 2004 and 2003.

Note 5 — Earnings per share

          The Company’s basic and diluted earnings per share (“EPS”) have been calculated in accordance with SFAS No. 128, Earnings Per Share. The Company’s net income is the same for both basic and diluted EPS. Basic EPS is based on the weighted-average number of common shares outstanding. Diluted EPS is based on the weighted-average number of common shares outstanding and common stock equivalents which would arise from the exercise of stock options. The following is a reconciliation of the weighted-average number of shares used for basic EPS and diluted EPS.

Note 6 — Comprehensive income

          The Company’s total comprehensive income, as calculated per SFAS No. 130, Reporting Comprehensive Income, was as follows:

          The difference between the Company’s net income and total comprehensive income for the three months ended March 31, 2004 and 2003 is due to the change in

Page 10

unrealized appreciation/depreciation on investments, the fair value adjustment and amortization of deferred losses relating to derivative financial instruments and the Company’s share of the other comprehensive loss on one of its joint venture investments, all net of tax.

Note 7 — Accounting for Derivatives and Hedging Activities

          Generally, the Company’s use of derivatives is limited to entering into interest rate swap agreements intended to hedge its debt financing terms. All derivatives subject to SFAS 133 are recognized on the balance sheet at their fair value. On the date the derivative contract is entered into, the Company designates the derivative as a hedge of the fair value of a recognized asset or liability (“fair value” hedge), or as a hedge of a forecasted transaction or of the variability of cash flows to be received or paid related to a recognized asset or liability (“cash flow” hedge). Changes in the fair value of a derivative that is highly effective as, and that is designated and qualifies as, a fair-value hedge, along with the loss or gain on the hedged asset or liability that is attributable to the hedged risk, are recorded in current-period earnings. Changes in the fair value of a derivative that is highly effective as, and that is designated and qualifies as, a cash-flow hedge are recorded in other comprehensive income, until earnings are affected by the variability of cash flows (e.g. when periodic settlements on a variable-rate asset or liability are recorded in earnings).

          The Company formally documents all relationships between hedging instruments and hedged items, as well as its risk-management objective and strategy for undertaking various hedge transactions. This process includes linking all derivatives that are designated as fair-value or cash-flow hedges to specific assets and liabilities on the balance sheet or forecasted transactions. The Company also formally assesses, both at the hedge’s inception and on an ongoing basis, whether the derivatives that are used in hedging transactions are highly effective in offsetting changes in fair values or cash flows of hedged items. If and when it is determined that a derivative is not highly effective as a hedge or that it has ceased to be a highly effective hedge, the Company discontinues hedge accounting prospectively.

Note 8 — Benefit Plans

The following table provides the components of net periodic benefit cost for the pension and other postretirement benefit plans:

The Company previously disclosed in its financial statements for the year ended December 31, 2003 that it expected to contribute $22.0 million to its pension plan in 2004. As of March 31, 2004, no contributions have been made. The Company presently anticipates contributing $22.0 million in 2004.

On December 8, 2003 the Medicare Prescription Drug, Improvement and Modernization Act of 2003 (“Act”) was signed into law. The Act introduces a prescription drug benefit under Medicare Part D as well as a federal subsidy to sponsors of the retiree health care benefit plans that provide a benefit that is at least actuarially equivalent to Medicare Part D. In accordance with the FASB Staff Position FAS 106-1, the Company has elected to defer recognizing the effects of the Act until authoritative guidance on the accounting for the federal subsidy is issued. Any measures of the accumulated postretirement benefit obligation or net periodic postretirement benefit cost in the financial statements or accompanying notes do not reflect the effect of the Act on the plan. Until specific authoritative guidance is issued the Company is unable to estimate the impact on the plan.

Overview

Business and General Environment

     The Company, through its subsidiary Mortgage Guaranty Insurance Corporation (“MGIC”), is the leading provider of private mortgage insurance in the United States to the home mortgage lending industry. The Company’s principal products are primary mortgage insurance and pool mortgage insurance. Primary mortgage insurance may be written on a flow basis, in which loans are insured in individual, loan-by-loan transactions, or may be written on a bulk basis, in which a portfolio of loans is individually insured in a single, bulk transaction.

The Company’s results of operations are affected by:

     Premiums written and earned in a year are influenced by:

     Premiums are generated by the insurance that is in force during all or a portion of the period. Hence, lower average insurance in force in one period compared to another is a factor that will reduce premiums written and earned, although this effect may be mitigated (or enhanced) by differences in the average premium rate between the two periods as well as by premium that is ceded. Also, cancellations and new insurance written during a quarter will generally have a greater effect on premiums written and earned in subsequent quarters than in the quarter in which these events occur.

Page 13

     The investment portfolio is comprised almost entirely of highly rated, fixed income securities. The principal factors that influence investment income are the size of the portfolio and its yield.

     Losses incurred are the expense that results from a payment delinquency on an insured loan. As explained under “Critical Accounting Policies” below, this expense is recognized only when a loan is delinquent. Losses incurred are generally affected by:

     The operating expenses of the Company generally vary primarily due to contract underwriting volume, which in turn generally varies with the level of mortgage origination activity. Contract underwriting generates fee income included in Other revenue.

     Joint venture income principally consists of the aggregate results of the Company’s investment in two less than majority owned joint ventures, Credit-Based Asset Servicing and Securitization LLC (“C-BASS”) and Sherman Financial Group LLC (“Sherman”). As used in this report, the term “Company” means the Company and its consolidated subsidiaries, which does not include joint ventures.

     2004 First Quarter Results

     The Company’s results of operations in the first three months of 2004 were principally affected by:

Page 14

     Losses incurred for the three months ended March 31, 2004 were $191 million compared to $142 million for the same period in 2003. This increase was principally the result of a higher number of delinquencies, increases in the estimates regarding how many delinquencies will eventually result in a claim and how much will be paid on claims, as well as an increase of $53 million in net losses paid.

     During the first three months of 2004, the Company’s written premiums were lower than written premiums in the first quarter of 2003 due to a decrease in new insurance written through the flow and bulk channels. Premiums earned during the first quarter of 2004 were higher than premiums earned during the first quarter of 2003 primarily due to the growth of bulk insurance in force and higher average premiums on bulk business.

     During the first three months of 2004, investment income increased slightly compared to the first quarter of 2003 as the increase in the portfolio was offset by a decline in pre-tax yield.

     Underwriting and other expenses decreased in the first three months of 2004 compared to the same period in 2003 as a result of decreases in expenses related to contract underwriting activity and amortization of deferred insurance policy acquisition costs.

     Income from joint ventures increased in the first three months of 2004 compared to the same period in 2003 due to higher earnings from each of C-BASS and Sherman.

RESULTS OF CONSOLIDATED OPERATIONS

Three Months Ended March 31, 2004 Compared With Three Months Ended March 31, 2003

New primary insurance written

     The amount of new primary insurance written by MGIC during the three months ended March 31, 2004 was $12.9 billion, compared to $24.1 billion in the same period of 2003, a decrease of $11.2 billion. New insurance written on a flow basis decreased $6.6 billion during the three months ended March 31, 2004 compared to the same period of 2003, principally reflecting a decline in refinance volume, which decreased from 52% of new insurance written for the first quarter of 2003 to 36% of new insurance written for the first quarter of 2004. New insurance written in the bulk channel decreased $4.6 billion

Page 15

during the three months ended March 31, 2004 compared to the same period of 2003, as discussed below. Consistent with a forecast made in mid-April 2004 by the Mortgage Bankers Association, which shows a decline in refinance activity in 2004, the Company expects new insurance written for the last three quarters of 2004 to be lower than for the comparable period in 2003.

Cancellations and insurance in force

     The $12.9 billion of new primary insurance written during the first quarter of 2004 was offset by the cancellation of $17.2 billion of insurance in force, and resulted in a net decrease of $4.3 billion in primary insurance in force, compared to new primary insurance written of $24.1 billion, the cancellation of $25.4 billion of insurance in force and a net decrease of $1.3 billion in primary insurance in force during the first quarter of 2003. Direct primary insurance in force was $185.3 billion at March 31, 2004 compared to $189.6 billion at December 31, 2003 and $195.7 billion at March 31, 2003.

     Cancellation activity has historically been affected by the level of mortgage interest rates. Cancellations generally move inversely to the change in the direction of interest rates, although they generally lag a change in direction. MGIC’s persistency rate (percentage of insurance remaining in force from one year prior) of 51.0% at March 31, 2004 increased from 47.1% at December 31, 2003 but was down from 53.8% at March 31, 2003. If refinance activity continues to decline in 2004 from its level in 2003, the Company expects that persistency will continue to improve in 2004, although the extent of the improvement is not possible to forecast accurately. The Company is not undertaking any obligation to provide an update of this expectation should it subsequently change.

Bulk transactions

     The Company’s writings of bulk insurance are in part sensitive to the volume of securitization transactions involving non-conforming loans. The Company’s writings of bulk insurance are also sensitive to competition from other methods of providing credit enhancement in a securitization, including an execution in which the subordinate tranches in the securitization rather than mortgage insurance bear the first loss from mortgage defaults. Competition from such an execution in turn depends on, among other factors, the yield at which investors are willing to purchase tranches of the securitization that involve a higher degree of credit risk compared to the yield for tranches involving the lowest credit risk (the difference in such yields is referred to as the spread) and the amount of credit for losses that a rating agency will give to mortgage insurance, which may be affected by the agency’s view of the outlook for the insurer’s claims-paying ability. As the spread declines, competition from an execution in which the subordinate tranches bear the first loss increases. As a result of the sensitivities discussed above, bulk volume can vary materially from period to period.

     New insurance written during the first quarter of 2004 for bulk transactions was $2.1 billion compared to $6.7 billion during the first quarter of 2003. The decline in volume reflected a decline in the spread referred to above.

     The Company expects that the loans that are included in bulk transactions will have delinquency and claim rates in excess of those on the Company’s flow business. The

Page 16

Company also expects that loans included in bulk transactions will have lower persistency than the Company’s flow business, although the persistency of bulk loans at March 31, 2004 and for the prior three quarters has been higher than the persistency of flow loans at those dates. The Company believes this is partially the result of the positive effect that pre-payment penalties had on bulk loan persistency as well as the historically unprecedented level of cancellations of flow business during this period. While the Company believes it has priced its bulk business to generate acceptable returns, there can be no assurance that the assumptions underlying the premium rates adequately address the risk of this business.

Pool insurance

     In addition to providing primary insurance coverage, the Company also insures pools of mortgage loans. New pool risk written during the three months ended March 31, 2004 and 2003 was $47 million and $284 million, respectively. The Company’s direct pool risk in force was $2.9 billion at March 31, 2004 and December 31, 2003, and was $2.7 billion at March 31, 2003. These risk amounts are contractual aggregate loss limits and for risk without such limits, risk is calculated at the estimated amount that would credit enhance the loans in the pool to a ‘AA’ level based on a rating agency model. At March 31, 2004 and 2003, there was $5.0 billion and $3.4 billion, respectively, of risk without such limits for which risk in force was calculated on this basis at $367 million and $205 million, respectively. During the three months ended March 31, 2004 and 2003, new risk written calculated on this basis was $14 million and $44 million, respectively.

Net premiums written and earned

     Net premiums written during the first quarter of 2004 decreased due to a decrease in new insurance written, both bulk and flow, when compared to the first quarter of 2003. Net premiums earned during the first quarter of 2004 increased compared to the first quarter of 2003 due to the growth of bulk insurance in force and higher average premiums on bulk business. The Company expects the average insurance in force during the second quarter of 2004 will be lower than during the second quarter of 2003. As a result, the Company does not anticipate that net premiums written or earned in the second quarter of 2004 will increase compared to the second quarter of 2003. The Company is not undertaking any obligation to provide an update of these expectations should they subsequently change.

Risk sharing arrangements

     For the quarter ended December 31, 2003, approximately 51% of the Company’s new insurance written on a flow basis was subject to captive mortgage reinsurance arrangements or risk sharing arrangements with the GSE compared to 52% for the quarter ended March 31, 2003. (New insurance written through the bulk channel is not subject to such arrangements.) The percentage of new insurance written during a period covered by such arrangements normally increases after the end of the period because, among other reasons, the transfer of a loan in the secondary market can result in a mortgage insured during a period becoming part of such an arrangement in a

Page 17

subsequent period. Therefore, the percentage of new insurance written covered by such arrangements is not shown for the current quarter. Premiums ceded in such arrangements are reported as ceded in the period in which they are ceded regardless of when the mortgage was insured.

Investment income

     Investment income for the first quarter of 2004 increased due to an increase in the amortized cost of average invested assets to $5.1 billion for the first quarter of 2004 from $4.5 billion for the first quarter of 2003, offset by a decrease in the average investment yield. The portfolio’s average pre-tax investment yield was 4.2% for the first quarter of 2004 and 4.6% for the first quarter of 2003. The portfolio’s average after-tax investment yield was 3.7% for the first quarter of 2004 and 4.1% for the first quarter of 2003. The Company’s net realized gains in the first quarter of 2004 and 2003 resulted primarily from the sale of fixed maturities.

Other revenue

     The decrease in other revenue is primarily the result of decreased revenue from contract underwriting.

Losses

     As discussed in “Critical Accounting Policies”, consistent with industry practice, loss reserves for future claims are established only for loans that are currently delinquent. (The terms “delinquent” and “default” are used interchangeably by the Company.) Loss reserves are established by management’s estimating the number of loans in the Company’s inventory of delinquent loans that will not cure their delinquency (historically, a substantial majority of delinquent loans have cured), which is referred to as the claim rate, and further estimating the amount that the Company will pay in claims on the loans that do not cure, which is referred to as claim severity. Estimation of losses that the Company will pay in the future is inherently judgmental. The conditions that affect the claim rate and claim severity include the current and future state of the domestic economy and the current and future strength of local housing markets.

     Net losses incurred increased 34% to $190.7 million in the first quarter of 2004, from $142.2 million in the same period of 2003. The increase was principally the result of a higher number of delinquencies, increases in the estimates regarding how many delinquencies will eventually result in a claim and how much will be paid on claims, as well as an increase of $53 million in net losses paid. The average primary claim paid for the three months ended March 31, 2004 was $23,972 compared to $22,856 for the same period in 2003.

     Information about the composition of the primary insurance default inventory at March 31, 2004, December 31, 2003 and March 31, 2003 appears in the table below.

Page 18

*A portion of A-minus and subprime credit loans is included in flow loans delinquent and the remainder is included in bulk loans delinquent. Most A-minus and subprime credit loans are written through the bulk channel. A-minus loans have FICO credit scores of 575-619, as reported to MGIC at the time a commitment to insure is issued, and subprime loans have FICO credit scores of less than 575.

     The pool notice inventory decreased from 28,135 at December 31, 2003 to 26,427 at March 31, 2004; the pool notice inventory was 27,006 at March 31, 2003.

Page 19

     Information about net losses paid in 2004 and 2003 appears in the table below.

     The Company has not written any new second mortgage risk for loans closing after 2001.

     As of March 31, 2004, 85% of MGIC’s insurance in force was written subsequent to December 31, 2000. On the Company’s flow business, the highest claim frequency years have typically been the third through fifth year after the year of loan origination. However, the pattern of claims frequency can be affected by many factors, including low persistency (which can have the effect of accelerating the period in the life of a book during which the highest claim frequency occurs) and deteriorating economic conditions (which can result in increasing claims following a period of declining claims). The Company expects the period of highest claims frequency on bulk loans will occur earlier than in the historical pattern on the Company’s flow business.

Underwriting and other expenses

     Among other items, the decrease in underwriting and other expenses is attributable to decreases in expenses related to contract underwriting activity and the amortization of deferred insurance policy acquisition costs (see Note 1 of the Notes to the Consolidated Financial Statements included elsewhere herein).

Consolidated ratios

     The consolidated insurance operations loss ratio was 55.8% for the first quarter of 2004 compared to 42.8% for the first quarter of 2003. The consolidated insurance operations expense and combined ratios were 13.7% and 69.5%, respectively, for the first quarter of 2004 compared to 14.3% and 57.1% for the first quarter of 2003.

Income taxes

     The effective tax rate was 27.3% in the first quarter of 2004, compared to 28.0% in the first quarter of 2003. During both periods, the effective tax rate was below the statutory rate of 35%, reflecting the benefits of tax-preferenced investments. The lower effective tax rate in 2004 principally resulted from a higher percentage of total income before tax being generated from tax-preferenced investments.

Joint ventures

     The Company’s equity in the earnings from the Sherman and C-BASS joint ventures with Radian Group Inc. and certain other joint ventures and investments, accounted for in accordance with the equity method of accounting, is shown separately, net of tax, on the Company’s consolidated statement of operations. The increase in income from joint ventures from the first quarter of 2003 to the first quarter of 2004 is primarily the result of increased equity earnings from each of C-BASS and Sherman.

     Total assets of C-BASS at March 31, 2004 and December 31, 2003 were approximately $3.050 billion and $3.181 billion, respectively. Total liabilities at March 31, 2004 and December 31, 2003 were approximately $2.561 billion and $2.707 billion, respectively, of which approximately $2.067 billion and $2.449 billion, respectively, was debt, virtually all of which matures within one-year or less. For the three months ended March 31, 2004 and 2003, revenues of approximately $106 million and $68 million, respectively, and expenses of approximately $61 million and $47 million, respectively, resulted in income before tax of approximately $45 million and $21 million, respectively. For the first three months of 2004 the Company’s share of the pre-tax earnings of C-BASS was $21.4 million compared to $9.8 million for the first three months of 2003. The increased contribution from C-BASS was primarily due to higher net interest income resulting from growth in C-BASS’s assets since the first quarter of 2003 and an unrealized gain relating to the termination of a C-BASS securitization. The Company’s investment in C-BASS on an equity basis at March 31, 2004 was $228.7 million.

     For the first three months of 2004 the Company’s share of the pre-tax earnings of Sherman was $12.6 million compared to $5.1 million for the first three months of 2003. The increased contribution from Sherman was primarily due to increased net revenue from portfolios owned during the 2003 and 2004 periods attributable to continuing collections and lower amortization on those portfolios and from higher collections due to growth in the amount of receivables portfolios owned by Sherman. The Company’s investment in Sherman on an equity basis at March 31, 2004 was $45.8 million, down from December 31, 2003 due to a $29 million distribution received during the first quarter of 2004.

     Additional information about the C-BASS and Sherman joint ventures is contained under “Management’s Discussion and Analysis of Financial Condition and Results of Operations—Results of Consolidated Operations—2003 Compared with 2002—Joint Ventures” in the Company’s Annual Report on Form 10-K for the year ended December 31, 2003.

Other Matters

     Under the Office of Federal Housing Enterprise Oversight’s (“OFHEO”) risk-based capital stress test for the GSEs, claim payments made by a private mortgage insurer on GSE loans are reduced below the amount provided by the mortgage insurance policy to reflect the risk that the insurer will fail to pay. Claim payments from an insurer whose claims-paying ability rating is ‘AAA’ are subject to a 3.5% reduction over the 10-year period of the stress test, while claim payments from a ‘AA’ rated insurer, such as MGIC, are subject to an 8.75% reduction. The effect of the differentiation among insurers is to require the GSEs to have additional capital for coverage on loans provided by a private

Page 21

mortgage insurer whose claims-paying rating is less than ‘AAA.’ As a result, there is an incentive for the GSEs to use private mortgage insurance provided by a ‘AAA’ rated insurer.

Financial Condition

     As of March 31, 2004, the Company had $178.3 million of short-term investments with maturities of 90 days or less, and 77% of the investment portfolio was invested in tax-preferenced securities. In addition, at March 31, 2004, based on book value, the Company’s fixed income securities were approximately 99% invested in ‘A’ rated and above, readily marketable securities, concentrated in maturities of less than 15 years.

     At March 31, 2004, the Company’s derivative financial instruments in its investment portfolio were immaterial. The Company places its investments in instruments that meet high credit quality standards, as specified in the Company’s investment policy guidelines; the policy also limits the amount of credit exposure to any one issue, issuer and type of instrument. At March 31, 2004, the effective duration of the Company’s fixed income investment portfolio was 5.8 years. This means that for an instantaneous parallel shift in the yield curve of 100 basis points there would be an approximate 5.8% change in the market value of the Company’s fixed income portfolio.

Liquidity and Capital Resources

     The Company’s consolidated sources of funds consist primarily of premiums written and investment income. Positive cash flows are invested pending future payments of claims and other expenses. Cash-flow shortfalls, if any, could be funded through sales of short-term investments and other investment portfolio securities subject to insurance regulatory requirements regarding the payment of dividends to the extent funds were required by other than the seller. Substantially all of the investment portfolio securities are held by the Company’s insurance subsidiaries.

     The Company has a $285 million commercial paper program, which is rated ‘A-1’ by Standard & Poor’s Rating Services and ‘P-1’ by Moody’s Investors Service. At March 31, 2004 and 2003, the Company had $100.4 million and $113.4 million in commercial paper outstanding with a weighted average interest rate of 1.10% and 1.33%, respectively.

     The Company had a $285 million credit facility available at March 31, 2004 expiring in 2006. Under the terms of the credit facility, the Company must maintain shareholders’ equity of at least $2.25 billion and MGIC must maintain a risk-to-capital ratio of not more than 22:1 and policyholders position (which includes MGIC’s statutory surplus and its contingency reserve) of not less than the amount required by Wisconsin insurance regulation. At March 31, 2004, the Company met these requirements. The facility is currently being used as a liquidity back up facility for the outstanding commercial paper. The remaining credit available under the facility after reduction for the amount necessary to support the commercial paper was $184.6 million at March 31, 2004.

     The Company had $300 million, 7.5% Senior Notes due in October 2005 and $200 million, 6% Senior Notes due in 2007 outstanding at March 31, 2004 and 2003. At

Page 22

March 31, 2004 and 2003, the market value of the outstanding debt was $641.7 million and $664.5 million, respectively.

     In May 2002, a swap designated as a cash flow hedge was amended to coincide with the credit facility. Under the terms of the swap contract, the Company pays a fixed rate of 5.43% and receives an interest rate based on LIBOR. The swap has an expiration date coinciding with the maturity of the credit facility and is designated as a cash flow hedge. The cash flow swap outstanding at March 31, 2004 and 2003 is evaluated quarterly using regression analysis with any ineffectiveness being recorded as an expense. To date this evaluation has not resulted in any hedge ineffectiveness. Swaps are subject to credit risk to the extent the counterparty would be unable to discharge its obligations under the swap agreements.

     Amortization expense on the interest rate swaps for the three months ended March 31, 2004 and 2003 of approximately $0.9 million and $0.6 million, respectively, was included in interest expense. Gains or losses arising from the amendment or termination of previously held interest rate swaps are deferred and amortized to interest expense over the life of the hedged items.

     The commercial paper, back-up credit facility and the Senior Notes are obligations of the Company and not of its subsidiaries. The Company is a holding company and the payment of dividends from its insurance subsidiaries is restricted by insurance regulation. MGIC is the principal source of dividend-paying capacity. For the remainder of 2004 MGIC can pay up to $133 million in dividends at a quarterly rate of approximately $44 million without the approval of the Office of the Commissioner of Insurance of the State of Wisconsin.

     During the first quarter of 2004, the Company repurchased 0.4 million shares of Common Stock under publicly announced programs at a cost of $26.7 million. At March 31, 2004, the Company had authority covering the purchase of an additional 7.2 million shares under these programs. For additional information regarding stock repurchases, see Item 2(e) of Part II of this Quarterly Report on Form 10-Q. From mid-1997 through March 31, 2004, the Company has repurchased 24.1 million shares under publicly announced programs at a cost of $1.2 billion. Funds for the shares repurchased by the Company since mid-1997 have been provided through a combination of debt, including the Senior Notes and the commercial paper, and internally generated funds.

     The Company’s principal exposure to loss is its obligation to pay claims under MGIC’s mortgage guaranty insurance policies. At March 31, 2004, MGIC’s direct (before any reinsurance) primary and pool risk in force (which is the unpaid principal balance of insured loans as reflected in the Company’s records multiplied by the coverage percentage, and taking account of any loss limit) was approximately $55.2 billion. In addition, as part of its contract underwriting activities, the Company is responsible for the quality of its underwriting decisions in accordance with the terms of the contract underwriting agreements with customers. Through March 31, 2004, the cost of remedies provided by the Company to customers for failing to meet the standards of the contracts has not been material. However, the decreasing trend of home mortgage interest rates over the last several years may have mitigated the effect of some of these costs since the general effect of lower interest rates can be to

Page 23

increase the value of certain loans on which remedies are provided. There can be no assurance that contract underwriting remedies will not be material in the future.

     The Company’s consolidated risk-to-capital ratio was 8.8:1 at March 31, 2004 compared to 9.4:1 at December 31, 2003. The decrease was due to an increase in capital and a decrease in risk in force during the first three months of 2004.

     The risk-to-capital ratios set forth above have been computed on a statutory basis. However, the methodology used by the rating agencies to assign claims-paying ability ratings permits less leverage than under statutory requirements. As a result, the amount of capital required under statutory regulations may be lower than the capital required for rating agency purposes. In addition to capital adequacy, the rating agencies consider other factors in determining a mortgage insurer’s claims-paying rating, including its historical and projected operating performance, business outlook, competitive position, management and corporate strategy.

Page 24

     For certain material risks of the Company’s business, see “Risk Factors” below.

Critical Accounting Policies

     The Company believes that the accounting policies described below involved significant judgments and estimates used in the preparation of its consolidated financial statements.

Loss reserves

     Reserves are established for reported insurance losses and loss adjustment expenses based on when notices of default on insured mortgage loans are received. Reserves are also established for estimated losses incurred on notices of default not yet reported by the lender. Consistent with industry practices, the Company does not establish loss reserves for future claims on insured loans which are not currently in default. Reserves are established by management using estimated claims rates and claims amounts on reported notices of default to estimate the loss. Amounts for salvage recoverable are considered in the determination of the reserve estimates. Adjustments to reserve estimates are reflected in the financial statements in the years in which the adjustments are made. The liability for reinsurance assumed is based on information provided by the ceding companies.

     The incurred but not reported (“IBNR”) reserves referred to above result from defaults occurring prior to the close of an accounting period, but which have not been reported to the Company by the lender. Consistent with reserves for reported defaults, IBNR reserves are established using estimated claims rates and claims amounts for the estimated number of defaults not reported.

     Reserves also provide for the estimated costs of settling claims, including legal and other expenses and general expenses of administering the claims settlement process.

Revenue recognition

     When the policy term ends, the primary mortgage insurance written by the Company is renewable at the insured’s option through continued payment of the premium in accordance with the schedule established at the inception of the policy term. The Company has no ability to reunderwrite or reprice these policies after issuance. Premiums written under policies having single and annual premium payments are initially deferred as unearned premium reserve and earned over the policy term. Premiums written on policies covering more than one year are amortized over the policy life in accordance with the expiration of risk which is the anticipated claim payment pattern based on historical experience. Premiums written on annual policies are earned on a monthly pro rata basis. Premiums written on monthly policies are earned as the monthly coverage is provided.

     Fee income of the non-insurance subsidiaries is earned and recognized as the services are provided and the customer is obligated to pay.

Page 25

Deferred insurance policy acquisition costs

     Costs associated with the acquisition of mortgage insurance policies, consisting of employee compensation and other policy issuance and underwriting expenses, are initially deferred and reported as deferred insurance policy acquisition costs (“DAC”). DAC arising from each book of business is charged against revenue in the same proportion that the underwriting profit for the period of the charge bears to the total underwriting profit over the life of the policies. The underwriting profit and the life of the policies are estimated and are reviewed quarterly and updated when necessary to reflect actual experience and any changes to key assumptions such as loss development. Interest is accrued on the unamortized balance of DAC.

Risk Factors

     The Company’s revenues and losses could be affected by the risk factors discussed below, which 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 the Company may make. Forward looking statements consist of statements which relate to matters other than historical fact. Among others, statements that include words such as the Company “believes”, “anticipates” or “expects”, or words of similar import, are forward looking statements. The Company is not undertaking any obligation to update any forward looking statements in this Management’s Discussion and Analysis.

     As the domestic economy deteriorates, more homeowners may default and the Company’s losses may increase.

     Losses result from events that reduce a borrower’s ability to continue to make mortgage payments, such as unemployment, and whether the home of a borrower who defaults on his mortgage can be sold for an amount that will cover unpaid principal and interest and the expenses of the sale. Favorable economic conditions generally reduce the likelihood that borrowers will lack sufficient income to pay their mortgages and also favorably affect the value of homes, thereby reducing and in some cases even eliminating a loss from a mortgage default. A deterioration in economic conditions generally increases the likelihood that borrowers will not have sufficient income to pay their mortgages and can also adversely affect housing values.

     The mix of business the Company writes also affects the likelihood of losses occurring. In recent years, a greater percentage of the Company’s volume than in the past has included segments that the Company views as having a higher probability of claim, including loans with LTV ratios over 95%, FICO credit scores below 620 or limited underwriting, including limited borrower documentation. A mid-April 2004 mortgage finance forecast of the Mortgage Bankers Association projects that quarterly mortgage originations in the United States are expected to decline materially in 2004 compared to 2003. In response to lower national origination volume, mortgage lenders may seek to maintain their own volume through a greater focus on lending to borrowers in segments that the Company views as having a higher probability of claim.

Page 26

     About 8% of the Company’s risk in force written through the flow channel, and more than half of the Company’s risk in force written through the bulk channel, consists of ARMs. The Company believes that during a prolonged period of rising interest rates, claims on ARMs would be substantially higher than for fixed rate loans, although the performance of ARMs has not been tested in such an environment.

     The performance of the servicing function on a mortgage loan, particularly a subprime loan, can affect the likelihood that the loan will default as well as the loss resulting from a default. The Company believes Fairbanks Capital Corp. (“Fairbanks”) is the servicer of approximately 1.3% of the loans insured by the Company and approximately 5.7% of the loans insured by the Company written through the bulk channel (a substantial number of which are subprime). The servicer ratings assigned to Fairbanks by Moody’s and S&P were downgraded during the second quarter of 2003 due in part to concerns expressed by those rating agencies about Fairbanks’ regulatory compliance and operational controls.

     Competition or changes in the Company’s relationships with its customers could reduce the Company’s revenues or increase its losses.

     Competition for private mortgage insurance premiums occurs not only among private mortgage insurers but also with mortgage lenders through captive mortgage reinsurance transactions. In these transactions, a lender’s affiliate reinsures a portion of the insurance written by a private mortgage insurer on mortgages originated or serviced by the lender.

     The level of competition within the private mortgage insurance industry has also increased as many large mortgage lenders have reduced the number of private mortgage insurers with whom they do business. At the same time, consolidation among mortgage lenders has increased the share of the mortgage lending market held by large lenders.

Page 27

     Our private mortgage insurance competitors include:

AGC Holdings Limited, a company whose mortgage insurance business was primarily reinsurance, recently announced that it intended to write mortgage guaranty insurance on a direct basis.

     If interest rates decline, house prices appreciate or mortgage insurance cancellation requirements change, the length of time that our policies remain in force could decline and result in declines in our revenue.

     In each year, most of the Company’s premiums are from insurance that has been written in prior years. As a result, the length of time insurance remains in force (which is also generally referred to as persistency) is an important determinant of revenues. The factors affecting the length of time the Company’s insurance remains in force include:

     During the 1990s, the Company’s year-end persistency ranged from a high of 87.4% at December 31, 1990 to a low of 68.1% at December 31, 1998. At March 31, 2004 persistency was at 51.0%, which was an improvement over the record low of 44.9% at September 30, 2003. Over the past several years, refinancing has become easier to accomplish and less costly for many consumers. Hence, even in an interest rate environment favorable to persistency improvement, the Company does not expect persistency will approach its December 31,1990 level.

     If the volume of low down payment home mortgage originations declines, the amount of insurance that the Company writes could decline which would reduce the Company’s revenues.

Page 28

     The factors that affect the volume of low down payment mortgage originations include:

     In general, the majority of the underwriting profit (premium revenue minus losses) that a book of mortgage insurance generates occurs in the early years of the book, with the largest portion of the underwriting profit realized in the first year. Subsequent years of a book generally result in modest underwriting profit or underwriting losses. This pattern of results occurs because relatively few of the claims that a book will ultimately experience occur in the first few years of the book, when premium revenue is highest, while subsequent years are affected by declining premium revenues, as persistency decreases due to loan prepayments, and higher losses.

     If all other things were equal, a decline in new insurance written in a year that followed a number of years of higher volume could result in a lower contribution to the mortgage insurer’s overall results. This effect may occur because the older books will be experiencing declines in revenue and increases in losses with a lower amount of underwriting profit on the new book available to offset these results.

     Whether such a lower contribution would in fact occur depends in part on the extent of the volume decline. Even with a substantial decline in volume, there may be offsetting factors that could increase the contribution in the current year. These offsetting factors include higher persistency and a mix of business with higher average premiums, which could have the effect of increasing revenues, and improvements in the economy, which could have the effect of reducing losses. In addition, the effect on the insurer’s overall results from such a lower contribution may be offset by decreases in the mortgage insurer’s expenses that are unrelated to claim or default activity, including those related to lower volume.

     The Company’s new insurance written during 2001 — 2003 was $86.1 billion, $92.5 billion and $96.8 billion, respectively and was $24.1 billion and $12.9 billion in the first quarters of 2003 and 2004, respectively. Consistent with a mid-April 2004 mortgage finance forecast of the Mortgage Bankers Association, which projects that quarterly mortgage originations in the United States are expected to decline materially in 2004

Page 29

compared to 2003, the Company expects new insurance written for the last three quarters of 2004 will be materially lower than for the comparable period in 2003.

     The amount of insurance the Company writes could be adversely affected if lenders and investors select alternatives to private mortgage insurance.

     These alternatives to private mortgage insurance include:

     While no data is publicly available, the Company believes that 80-10-10 loans and related products are a significant percentage of mortgage originations and that their use continues to increase.

     Changes in the business practices of Fannie Mae and Freddie Mac could reduce the Company’s revenues or increase its losses.

     The business practices of Fannie Mae and Freddie Mac affect the entire relationship between them and mortgage insurers and include:

Page 30

     The mortgage insurance industry is subject to litigation risk.

     Consumers are bringing a growing number of lawsuits against home mortgage lenders and settlement service providers. In recent years, seven mortgage insurers, including the Company’s MGIC subsidiary, have been involved in litigation alleging violations of the Real Estate Settlement Procedures Act, which is commonly known as RESPA. MGIC’s settlement of litigation against it under RESPA became final in October 2003. There can be no assurance that MGIC will not be subject to future litigation under RESPA.

     In March 2003 an action against MGIC was filed in Federal District Court in Orlando, Florida seeking certification of a nationwide class of consumers who were required to pay for private mortgage insurance written by MGIC and whose loans were insured at less than MGIC’s “best available rate” based on credit scores obtained by MGIC. (A portion of MGIC’s A minus and subprime premium rates are based in part on the credit score of the borrower.) The action alleges that the Federal Fair Credit Reporting Act (“FCRA”) requires a notice to borrowers of such “adverse action” and that MGIC has violated FCRA by failing to give such notice. The action seeks statutory damages (which in the case of willful violations, in addition to punitive damages, may be awarded in an amount of $100 to $1,000 per class member) and/or actual damages of the persons in the class, and attorneys fees, as well as declaratory and injunctive relief. The action also alleges that the failure to give notice to borrowers in Florida in the circumstances alleged is a violation of Florida’s Unfair and Deceptive Acts and Practices Act and seeks declaratory and injunctive relief for such violation. In December 2003, the Court denied MGIC’s motion seeking dismissal of the portion of the case covering damages under FCRA but dismissed the remainder of the case. There can be no assurance that the outcome of the litigation will not materially affect the Company’s financial position or results of operations. Similar actions have been filed against six other mortgage insurers.

     Net premiums written could be adversely affected if the Department of Housing and Urban Development reproposes and adopts a regulation under the Real Estate Settlement Procedures Act that is equivalent to a proposed regulation that was recently withdrawn.

     The regulations of the Department of Housing and Urban Development under the Real Estate Settlement Procedures Act prohibit paying lenders for the referral of settlement services, including mortgage insurance, and prohibit lenders from receiving such payments. In July 2002, the Department of Housing and Urban Development proposed a regulation that would exclude from these anti-referral fee provisions settlement services included in a package of settlement services offered to a borrower at a guaranteed price. HUD withdrew this proposed regulation in March 2004. Under the proposed regulation, if mortgage insurance was required on a loan, the package must include any mortgage insurance premium paid at settlement. Although certain

Page 31

state insurance regulations prohibit an insurer’s payment of referral fees, had this regulation been adopted in this form, the Company’s revenues could have been adversely affected to the extent that lenders offered such packages and received value from the Company in excess of what they could have received were the anti-referral fee provisions of the Real Estate Settlement Procedures Act to apply and if such state regulations were not applied to prohibit such payments.

ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

     At March 31, 2004, the Company’s derivative financial instruments in its investment portfolio were immaterial. The Company places its investments in instruments that meet investment grade credit quality standards, as specified in the Company’s investment policy guidelines; the policy also limits the amount of credit exposure to any one issue, issuer and type of instrument. At March 31, 2004, the effective duration of the Company’s fixed income investment portfolio was 5.8 years. This means that for each instantaneous parallel shift in the yield curve of 100 basis points there would be an approximate 5.8% change in the market value of the Company’s fixed income investment portfolio.

     The Company’s borrowings under its commercial paper program are subject to interest rates that are variable. See the fifth paragraph under “Management’s Discussion and Analysis of Financial Condition and Results of Operations-Liquidity and Capital Resources” for a discussion of the Company’s interest rate swaps.

ITEM 4. CONTROLS AND PROCEDURES

     The Company’s management, with the participation of the Company’s principal executive officer and principal financial officer, has evaluated the Company’s 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, the Company’s principal executive officer and principal financial officer concluded that such controls and procedures were effective as of the end of such period. The Company’s management, with the participation of the Company’s principal executive officer and principal financial officer, also evaluated whether any change in the Company’s internal control over financial reporting that occurred during the quarter covered by this Quarterly Report on Form 10-Q materially affected, or is reasonably likely to materially affect, the Company’s internal control over financial reporting. Based on that evaluation, there has been no such change during such quarter.
