Part I

Item 1. Business.

A. General

     MGIC Investment Corporation (the “Company”) is a holding company which, through its wholly owned subsidiary Mortgage Guaranty Insurance Corporation (“MGIC”), is the leading provider of private mortgage insurance in the United States to the home mortgage lending industry. Private mortgage insurance covers residential first mortgage loans and expands home ownership opportunities by enabling people to purchase homes with less than 20% down payments. If the homeowner defaults, private mortgage insurance reduces and, in some instances, eliminates the loss to the insured institution. Private mortgage insurance also facilitates the sale of low down payment and other mortgage loans in the secondary mortgage market, including to the Federal National Mortgage Association (“Fannie Mae”) and the Federal Home Loan Mortgage Corporation (“Freddie Mac”) (Fannie Mae and Freddie Mac are collectively referred to as the “GSEs”). In addition to mortgage insurance on first liens, the Company, through other subsidiaries, provides lenders with various underwriting and other services and products related to home mortgage lending.

     MGIC is licensed in all 50 states of the United States, the District of Columbia and Puerto Rico. The Company is a Wisconsin corporation. Its principal office is located at MGIC Plaza, 250 East Kilbourn Avenue, Milwaukee, Wisconsin 53202 (telephone number (414) 347-6480).

     The Company and its business may be materially affected by the factors discussed in “Management’s Discussion and Analysis — Risk Factors” in Item 7 of this Annual Report on Form 10-K. These factors may also cause actual results to differ materially from the results contemplated by forward looking statements that the Company may make.

B. The MGIC Book

  Types of Product

     In general, there are two principal types of private mortgage insurance: “primary” and “pool.”

- 1 -

     Primary Insurance. Primary insurance provides mortgage default protection on individual loans and covers unpaid loan principal, delinquent interest and certain expenses associated with the default and subsequent foreclosure (collectively, the “claim amount”). In addition to the loan principal, the claim amount is affected by the mortgage note rate and the time necessary to complete the foreclosure process. The insurer generally pays the coverage percentage of the claim amount specified in the primary policy, but has the option to pay 100% of the claim amount and acquire title to the property. Primary insurance generally applies to owner occupied, first mortgage loans on one-to-four family homes, including condominiums. Primary coverage can be used on any type of residential mortgage loan instrument approved by the mortgage insurer. References in this document to amounts of insurance written or in force, risk written or in force and other historical data related to MGIC’s insurance refer only to direct (before giving effect to reinsurance) primary insurance, unless otherwise indicated. References in this document to “primary insurance” include insurance written in bulk transactions (see “Bulk Transactions” below) that is supplemental to mortgage insurance written in connection with the origination of the loan or that reduces a lender’s credit risk to less than 50% of the value of the property. Effective with the third quarter of 2001, in reports by private mortgage insurers to the trade association for the private mortgage insurance industry, mortgage insurance that is supplemental to other mortgage insurance or that reduces a lender’s credit risk to less than 50% of the value of the property is classified as pool insurance. The trade association classification is used by members of the private mortgage insurance industry in reports to a mortgage industry publication that computes and publishes primary market share information.

     Primary 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 each loan in a portfolio of loans is individually insured in a single, bulk transaction. New insurance written on a flow basis was $71.1 billion in 2003 compared to $70.0 billion in 2002 and $60.4 billion in 2001. New insurance written for bulk transactions was $25.7 billion during 2003 compared to $22.5 billion for 2002 and $25.7 billion for 2001.

     The following table shows, on a direct basis, primary insurance in force (the unpaid principal balance of insured loans as reflected in MGIC’s records) and primary risk in force (the coverage percentage applied to the unpaid principal balance), for insurance that has been written by MGIC (the “MGIC Book”) as of the dates indicated:

- 2 -

Primary Insurance and Risk In Force

     The coverage percentage provided by MGIC is determined by the lender. For loans sold by lenders to Fannie Mae or Freddie Mac, the coverage percentage must comply with the requirements established by the particular GSE to which the loan is delivered.

     MGIC charges higher premium rates for higher coverages. MGIC believes depth of coverage requirements have no significant impact on frequency of default. Higher coverage percentages generally result in increased severity (which is the amount paid on a claim), and lower coverage percentages generally result in decreased severity. In accordance with industry accounting practice, reserves for losses are only established for loans in default. Because relatively few defaults occur in the early years of a book of business (see “Past Industry Losses; Defaults; and Claims, Claims” below), the higher premium revenue from deeper coverage is recognized before any higher losses resulting from that deeper coverage may be incurred. MGIC’s premium pricing methodology generally targets substantially similar returns on capital regardless of the depth of coverage. However, there can be no assurance that changes in the level of premium rates adequately reflect the risks associated with changes in the depth of coverage.

     In partnership with mortgage insurers, the GSEs are also offering programs under which, on delivery of an insured loan to a GSE, the primary coverage is restructured to an initial shallow tier of coverage followed by a second tier that is subject to an overall loss limit and compensation may be paid to the GSE reflecting services or other benefits realized by the mortgage insurer from the coverage conversion. Lenders receive guaranty fee relief from the GSEs on mortgages delivered with these restructured coverages.

     Mortgage insurance coverage cannot be terminated by the insurer, except for non-payment of premium, and remains renewable at the option of the insured lender, generally at the renewal rate fixed when the loan was initially insured. Lenders may cancel insurance written on a flow basis at any time at their option or because of mortgage repayment, which may be accelerated because of the refinancing of mortgages. In the case of a loan purchased by Freddie Mac or Fannie Mae, a borrower meeting certain conditions may require the mortgage servicer to cancel insurance upon the borrower’s request when the principal balance of the loan is 80% or less of the home’s current value.

     Under the federal Homeowners Protection Act (the “HPA”) a borrower has the right to stop paying premiums for private mortgage insurance on loans closed after July 28, 1999 secured

- 3 -

by a property comprised of one dwelling unit that is the borrower’s primary residence when certain loan-to-value ratio (“LTV ratio”) thresholds determined by the value of the home at loan origination and other requirements are met. In general, a borrower may stop making mortgage insurance payments when the LTV ratio is scheduled to reach 80% (based on the loan’s amortization schedule) or actually reaches 80% if the borrower so requests and if certain requirements relating to the borrower’s payment history and the absence of junior liens and a decline in the property’s value since origination are satisfied. In addition, a borrower’s obligation to make payments for private mortgage insurance generally terminates regardless of whether a borrower so requests when the LTV ratio (based on the loan’s amortization schedule) reaches 78% of the unpaid principal balance of the mortgage and the borrower is (or thereafter becomes) current in his mortgage payments. A borrower’s right to stop paying for private mortgage insurance applies only to borrower paid mortgage insurance. The HPA requires that lenders give borrowers certain notices with regard to the cancellation of private mortgage insurance.

     In addition, some states require that mortgage servicers periodically notify borrowers of the circumstances in which they may request a mortgage servicer to cancel private mortgage insurance and some states allow the borrower to require the mortgage servicer to cancel private mortgage insurance under certain circumstances or require the mortgage servicer to cancel such insurance automatically in certain circumstances.

     Coverage tends to continue in areas experiencing economic contraction and housing price depreciation. The persistency of coverage in such areas coupled with cancellation of coverage in areas experiencing economic expansion and housing price appreciation can increase the percentage of the insurer’s portfolio comprised of loans in economically weak areas. This development can also occur during periods of heavy mortgage refinancing because refinanced loans in areas of economic expansion experiencing property value appreciation are less likely to require mortgage insurance at the time of refinancing, while refinanced loans in economically weak areas not experiencing property value appreciation are more likely to require mortgage insurance at the time of refinancing or not qualify for refinancing at all and, thus, remain subject to the mortgage insurance coverage.

     The percentage of primary risk written with respect to loans representing refinances was 48.7% in 2003 compared to 43.8% in 2002, 43.7% in 2001 and 18% in 2000. When a borrower refinances an MGIC-insured mortgage loan by paying it off in full with the proceeds of a new mortgage that is also insured by MGIC, the insurance on that existing mortgage is cancelled, and insurance on the new mortgage is considered to be new primary insurance written. Therefore, continuation of MGIC’s coverage from a refinanced loan to a new loan results in both a cancellation of insurance and new insurance written.

     In addition to varying with the coverage percentage, MGIC’s premium rates vary depending upon the perceived risk of a claim on the insured loan and, thus, take into account the LTV, the loan type (fixed payment versus non-fixed payment) and mortgage term and, for A- and subprime loans and certain other loans, the location of the borrower’s credit score within a range of credit scores. In general, A- loans have FICO scores between 575 and 619 and subprime loans have FICO credit scores of less than 575.

     Premium rates cannot be changed after the issuance of coverage. Because the Company believes that over the long term each region of the United States is subject to similar factors

- 4 -

affecting risk of loss on insurance written, MGIC generally utilizes a nationally based, rather than a regional or local, premium rate policy.

     The borrower’s mortgage loan instrument may require the borrower to pay the mortgage insurance premium (“borrower paid mortgage insurance”) or there may be no such requirement imposed on the borrower, in which case the premium is paid by the lender, who may recover the premium through an increase in the note rate on the mortgage (“lender paid mortgage insurance”). Almost all of MGIC’s primary insurance in force and new insurance written, other than through bulk transactions, is borrower paid mortgage insurance. New insurance written through bulk transactions is generally paid by the securitization vehicles that hold the mortgages; the mortgage note rate generally does not reflect the premium for the mortgage insurance.

     Under the monthly premium plan, a monthly premium payment is made to MGIC to provide only one month of coverage, rather than one year of coverage provided by the annual premium plan. Under the annual premium plan, the initial premium is paid to MGIC in advance, and earned over the next twelve months of coverage, with annual renewal premiums paid in advance thereafter and earned over the subsequent twelve months of coverage. The annual premiums can be paid with either a higher premium rate for the initial year of coverage and lower premium rates for the renewal years, or with premium rates which are equal (level) for the initial year and subsequent renewal years. Under the single premium plan, a single payment is made to MGIC, covering a specified term exceeding 12 months.

     During each of the last three years, the monthly premium plan represented more than 90% of MGIC’s new insurance written. The annual premium plan represented substantially all of the remaining new insurance written.

     Pool Insurance. Pool insurance is generally used as an additional “credit enhancement” for certain secondary market mortgage transactions. Pool insurance generally covers the loss on a defaulted mortgage loan which exceeds the claim payment under the primary coverage, if primary insurance is required on that mortgage loan, as well as the total loss on a defaulted mortgage loan which did not require primary insurance. Pool insurance may have a stated aggregate loss limit and may also have a deductible under which no losses are paid by the insurer until losses exceed the deductible.

     New pool risk written during 2003 was $862 million and was $674 million in 2002. New pool risk written during these years was comprised of risk associated with loans delivered to Freddie Mac and Fannie Mae (“agency pool insurance”), loans delivered to the Federal Home Loan Banks under their mortgage purchase programs and loans made under state housing finance programs. Net (giving effect to external reinsurance) MGIC Book pool risk in force at December 31, 2003 was $2.7 billion compared to $2.4 billion and $1.8 billion at December 31, 2002 and 2001, respectively. The risk amounts referred to above are contractual aggregate loss limits and, for the years ended December 31, 2003 and 2002, for $4.9 billion and $3.0 billion, respectively, of risk without such limits, risk is calculated at $192 million and $147 million, respectively, for new risk written and $353 million and $161 million, respectively, for risk in force, representing the estimated amount that would credit enhance these loans to a ‘AA’ level based on a rating agency model.

- 5 -

     The settlement of a nationwide class action alleging that MGIC violated the Real Estate Settlement Procedures Act (“RESPA”) by providing agency pool insurance and entering into other transactions with lenders that were not properly priced (the “RESPA Litigation”) became final in October 2003. See Item 3 “Legal Proceedings.” In a February 1, 1999 circular addressed to all mortgage guaranty insurers licensed in New York, the New York Department of Insurance (“NYID”) advised that “significantly underpriced” agency pool insurance would violate the provisions of New York insurance law that prohibit mortgage guaranty insurers from providing lenders with inducements to obtain mortgage guaranty business. In a January 31, 2000 letter addressed to all mortgage guaranty insurers licensed in Illinois, the Illinois Department of Insurance advised that providing pool insurance at a “discounted or below market premium” in return for the referral of primary mortgage insurance would violate Illinois law.

     Risk Sharing Arrangements. MGIC’s products include risk sharing arrangements with the GSEs and captive mortgage reinsurance in which an affiliate of a lender reinsures a portion of the risk on loans originated or purchased by the lender which have MGIC primary insurance. During the nine months ended September 30, 2003 and the year ended December 31, 2002, about 53% of MGIC’s new insurance written on a flow basis was subject to risk sharing arrangements. (New insurance written through the bulk channel is not subject to such arrangements.) The percentage of new insurance written during a quarter covered by such arrangements normally increases after the end of the quarter because, among other reasons, the transfer of a loan in the secondary market can result in a mortgage insured during a quarter becoming part of such an arrangement in a subsequent quarter. Therefore, the percentage of new insurance written for 2003 covered by such arrangements is shown only for the nine months ended September 30, 2003. The complaint in the RESPA Litigation alleged that MGIC pays “inflated” captive mortgage reinsurance premiums in violation of RESPA.

     A substantial portion of the Company’s captive mortgage reinsurance arrangements are structured on an excess of loss basis. At the beginning of the second quarter of 2003 the Company stopped participating in certain excess of loss risk sharing arrangements on terms which are generally present in the market. The captive mortgage reinsurance programs of larger lenders generally are not consistent with the Company’s position. The Company’s position with respect to such risk sharing arrangements resulted in a reduction in business from such lenders. See “The MGIC Book—Customers.”

     External Reinsurance. At December 31, 2003, disregarding reinsurance under captive structures, less than 2% of MGIC’s insurance in force was externally reinsured. Reinsuring against possible loan losses does not discharge MGIC from liability to a policyholder; however, the reinsurer agrees to indemnify MGIC for the reinsurer’s share of losses incurred.

     Bulk Transactions. In bulk transactions, the individual loans in the insured portfolio are insured to specified levels of coverage. The premium in a bulk transaction, which is negotiated with the securitizer or other owner of the loans, is based on the mortgage insurer’s evaluation of the overall risk of the insured loans included in the transaction and is often a composite rate applied to all of the loans in the transaction.

     In general, the loans insured by MGIC in bulk transactions consist of A- loans; subprime loans; cash out refinances that exceed the standard underwriting requirements of the GSEs; jumbo loans; and loans with reduced underwriting documentation. A- loans have FICO scores

- 6 -

between 575 and 619 and subprime loans have FICO credit scores of less than 575. A jumbo loan has an unpaid principal balance that exceeds the conforming loan limit. The conforming loan limit is the maximum unpaid principal amount of a mortgage loan that can be purchased by the GSEs. The conforming loan limit is subject to annual adjustment, and for mortgages covering a home with one dwelling unit is $333,700 for 2004 and was $322,700 in 2003 and $300,700 in 2002.

     Approximately 55% of MGIC’s bulk loan risk in force at December 31, 2003 and 2002 had FICO credit scores of at least 620. Approximately 30% of MGIC’s bulk loan risk in force at December 31, 2003 had A- FICO credit scores compared to 27% at December 31, 2002, and approximately 15% had subprime credit scores at December 31, 2003 compared to 18% at December 31, 2002. Most of the subprime loans insured by MGIC in 2003 were insured in bulk transactions. More than 40% of MGIC’s bulk loan risk in force at December 31, 2003 had LTV ratios of 80% and below compared to more than 48% at December 31, 2002.

     New insurance written for bulk transactions was $25.7 billion during 2003 compared to $22.5 billion for 2002 and $25.7 billion for 2001. 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 depends on, among other factors, the yield at which investors are willing to purchase tranches of the securitization with 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.

  Customers

     Originators of residential mortgage loans such as mortgage bankers, savings institutions, commercial banks, mortgage brokers, credit unions and other lenders have historically determined the placement of mortgage insurance written on flow basis and as a result are the customers of MGIC. To obtain primary insurance from MGIC written on flow basis, a mortgage lender must first apply for and receive a mortgage guaranty master policy (“Master Policy”) from MGIC. MGIC had approximately 13,700 master policyholders at December 31, 2003 (not including policies issued to branches and affiliates of large lenders). In 2003, MGIC issued coverage on mortgage loans for approximately 4,700 of its master policyholders. MGIC’s top 10 customers generated 33.1% of its new insurance written on a flow basis in 2003, compared to 39.5% in 2002, 38.4% in 2001 and 33.7% in 1998. The share of MGIC’s flow business from its top 10 customers in 2003 was affected by its position on certain excess of loss captive reinsurance arrangements. See “Types of Product — Risk Sharing Arrangements” above.

- 7 -

  Sales and Marketing and Competition

     Sales and Marketing. MGIC sells its insurance products through its own employees, located throughout the United States. At December 31, 2003, MGIC had 32 underwriting centers located in 22 states and in Puerto Rico.

     Competition. For flow business, MGIC and other private mortgage insurers compete directly with federal and state governmental and quasi-governmental agencies, principally the FHA and, to a lesser degree, the Veterans Administration (“VA”). These agencies sponsor government-backed mortgage insurance programs, which during 2003 and 2002 accounted for approximately 36% of the total low down payment residential mortgages which were subject to governmental or private mortgage insurance. See “Regulation — Indirect Regulation” below. Loans insured by the FHA cannot exceed maximum principal amounts which are determined by a percentage of the conforming loan limit. For 2004, the maximum FHA loan amount for homes with one dwelling unit in “high cost” areas is as high as $290,319 and was as high as $280,749 in 2003. Loans insured by the VA do not have mandated maximum principal amounts but have maximum limits on the amount of the guaranty provided by the VA to the lender. For loans closed after December 27, 2001 the maximum VA guarantee is $60,000.

     In addition to competition from the FHA and the VA, MGIC and other private mortgage insurers face competition from state-supported mortgage insurance funds in several states, including California and New York. From time to time, other state legislatures and agencies consider expansions of the authority of their state governments to insure residential mortgages.

     Private mortgage insurers may also be subject to competition from Fannie Mae and Freddie Mac to the extent the GSEs are compensated for assuming default risk that would otherwise be insured by the private mortgage insurance industry. Fannie Mae and Freddie Mac each have programs under which an up-front delivery fee can be paid to the GSE and primary mortgage insurance coverage is substantially reduced compared to the coverage requirements that would apply in the absence of the program. See “Types of Product—Primary Insurance” above. In October 1998, Freddie Mac’s charter was amended (and the amendment immediately repealed) to give Freddie Mac flexibility to use protection against default in addition to private mortgage insurance and the two other types of credit enhancement required by the charter for low down payment mortgages purchased by Freddie Mac. In addition, to the extent up-front delivery fees are not retained by the GSEs to compensate for their assumption of default risk, and are used instead to purchase supplemental coverage from mortgage insurers, the resulting concentration of purchasing power in the hands of the GSEs could increase competition among insurers to provide such coverage.

     The capital markets may also develop as competitors to private mortgage insurers. During 1998, a newly-organized off-shore company funded by the sale of notes to institutional investors provided “reinsurance” to Freddie Mac against default on a specified pool of mortgages owned by Freddie Mac.

     MGIC and other mortgage insurers also compete with transactions structured to avoid mortgage insurance on low down payment mortgage loans. Such transactions include self-insuring, and “80-10-10” loans, which are loans comprised of both a first and a second mortgage (for example, an 80% LTV first mortgage and a 10% LTV second mortgage), with the LTV ratio of the first mortgage below what investors require for mortgage insurance, compared to a loan in which the first mortgage covers the entire borrowed amount (which in the preceding example would be a

- 8 -

90% LTV mortgage). Captive mortgage reinsurance and similar transactions also result in mortgage originators receiving a portion of the premium and the risk.

     The private mortgage insurance industry currently consists of eight active mortgage insurers and their affiliates; one of the eight is a joint venture in which a mortgage insurer is one of the joint venturers. The names of these mortgage insurers are listed in “Management’s Discussion and Analysis—Risk Factors” in Item 7 of this Annual Report on Form 10-K. According to Inside Mortgage Finance, a mortgage industry publication, which obtains its data from reports to it by MGIC and other mortgage insurers that are to be prepared on the same basis as the reports by insurers to the trade association for the private mortgage insurance industry, for 1995 and subsequent years, MGIC has been the largest private mortgage insurer based on new primary insurance written (with a market share of 21.9% in 2003, 24.8% in 2002 and 25.0% in 2001) and at December 31, 2003, MGIC also had the largest book of direct primary insurance in force. MGIC’s market share in 2003 was negatively impacted by its position on certain excess of loss captive reinsurance arrangements. See “Types of Product — Risk Sharing Arrangements” above. Effective with the third quarter of 2001, these reports do not include as “primary mortgage insurance” insurance on certain loans classified by MGIC as primary insurance, such as loans insured through bulk transactions that already had mortgage insurance placed on the loans at origination.

     The private mortgage insurance industry is highly competitive. The Company believes it competes with other private mortgage insurers for business written through the flow channel principally on the basis of programs involving captive mortgage reinsurance, agency pool insurance, and other similar structures involving lenders; the provision of contract underwriting and related fee-based services to lenders; the provision of other products and services that meet lender needs for risk management, affordable housing, loss mitigation, capital markets and training support; the strength of MGIC’s management team and field organization; and the effective use of technology and innovation in the delivery and servicing of MGIC’s insurance products. The Company believes MGIC’s additional competitive strengths, compared to other private insurers, are its customer relationships, name recognition, reputation and the depth of its database covering loans it has insured. The Company believes it competes for bulk business principally on the basis of the premium rate and the portion of loans submitted for insurance that the Company is willing to insure.

     The complaint in the RESPA Litigation alleged, among other things, that captive mortgage reinsurance, agency pool insurance, and contract underwriting as provided by the Company violated RESPA.

     Certain private mortgage insurers compete for flow business by offering lower premium rates than other companies, including MGIC, either in general or with respect to particular classes of business. MGIC on a case-by-case basis will adjust premium rates, generally depending on the risk characteristics, loss performance or class of business of the loans to be insured, or the costs associated with doing such business.

     In the third quarter of 2001, the Office of Federal Housing Enterprise Oversight (“OFHEO”) adopted a risk-based capital stress test for the GSEs, which was amended in February 2002. One of the elements of the stress test is that future 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

- 9 -

rating (which in this document is also referred to as a “financial strength 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 a 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 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.

  Contract Underwriting and Related Services

     The Company performs contract underwriting services for lenders in which the Company judges whether the data relating to the borrower and the loan contained in the lender’s mortgage loan application file comply with the lender’s loan underwriting guidelines. The Company also provides an interface to submit such data to the automated underwriting systems of the GSEs, which independently judge the data. These services are provided for loans that require private mortgage insurance as well as for loans that do not require private mortgage insurance. A material portion of the Company’s new insurance written through the flow channel in recent years involved loans for which the Company provided contract underwriting services. The complaint in the RESPA Litigation alleged, among other things, that the pricing of contract underwriting provided by the Company violated RESPA.

     As part of its contract underwriting services, the Company is responsible for the quality of its underwriting decisions in accordance with the terms of the contract underwriting agreements with customers. Through December 31, 2003, 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 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.

  Risk Management

     MGIC believes that mortgage credit risk is materially affected by

MGIC believes that mortgage credit risk is also affected by the origination practices of the lender and the condition of the housing market in the area in which the property is located.

     MGIC believes that, excluding other factors, claim incidence increases for loans with lower FICO credit scores compared to loans with higher FICO credit scores; for loans with less than full underwriting documentation compared to loans with full underwriting documentation; for loans with higher LTV ratios compared to loans with lower LTV ratios; for ARMs during a prolonged

- 10 -

period of rising interest rates compared to fixed rate loans in such a rate environment; for loans in which the original loan amount exceeds the conforming loan limit compared to loans below such limit; and for cash out refinance loans compared to rate and term refinance loans. MGIC charges higher premium rates to reflect the increased risk of claim incidence that it perceives is associated with a loan. However, there can be no assurance that MGIC’s premium rates adequately reflect the increased risk, particularly in a period of economic recession.

     There are also other types of loan characteristics relating to the individual loan or borrower which affect the risk potential for a loan. The presence of a number of higher-risk characteristics in a loan materially increases the likelihood of a claim on such a loan unless there are other characteristics to lower the risk.

     Delegated Underwriting and GSE Automated Underwriting Approvals. Delegated underwriting is a program under which approved lenders are allowed to commit MGIC to insure loans originated through the flow channel utilizing their own underwriting guidelines and underwriting evaluation. Some major lenders having delegated underwriting authority use their own proprietary automated underwriting services to apply their underwriting guidelines to loans. In addition, since 2000, loans approved by the automated underwriting services of the GSEs have been automatically approved for MGIC mortgage insurance.

     During 2003, a substantial majority of the loans insured by MGIC through the flow channel were approved as a result of loan approvals by the automated underwriting services of the GSEs or though delegated underwriting programs, including those utilizing proprietary underwriting services. MGIC expects the portion of its flow business that is approved in this manner to continue to increase. The loan approval criteria of automated underwriting services are within the risk management discretion and control of the GSEs or the lender operating the service. As a result of accepting the loan approval decisions of these services, MGIC does not have the ability to control in advance the risk characteristics of such loans. MGIC’s risk management approach to such flow business has been to monitor periodically the credit quality of the loans it has recently insured in this manner. If as a result of such review MGIC perceives certain loans insured in this manner have an unacceptably higher risk of claim, MGIC can continue to insure loans with such characteristics that are thereafter submitted to it at A- rates. In addition, in the case of loans approved other than through the automated underwriting systems of the GSEs, MGIC can decline to continue to insure loans having such characteristics.

     Bulk Transactions Risk Management. The premium for loans insured in a bulk transaction is determined by MGIC’s evaluation of the credit risk of the loans included in the transaction based on information about the loans represented to MGIC by the securitizer. Individual loan files are generally not reviewed in advance of the issuance of an insurance commitment but are reviewed at the time a claim is made to confirm that the loan involved in the claim generally conforms to the representations that were previously made. MGIC has the right to rescind coverage for loans that do not conform to such representations.

  Past Industry Losses; Defaults; and Claims

     Past Industry Losses. The private mortgage insurance industry experienced substantial unanticipated incurred losses in the mid-to-late 1980s. From the 1970s until 1981, rising home prices in the United States generally led to profitable insurance underwriting results for the industry

- 11 -

and caused private mortgage insurers to emphasize market share. To maximize market share, until the mid-1980s, private mortgage insurers employed liberal underwriting practices, and charged premium rates which, in retrospect, generally did not adequately reflect the risk assumed (particularly on pool insurance). These industry practices compounded the losses which resulted from changing economic and market conditions which occurred during the early and mid-1980s, including (i) severe regional recessions and attendant declines in property values in the nation’s energy producing states; (ii) the development by lenders of new mortgage products to defer the impact on home buyers of double digit mortgage interest rates; and (iii) changes in federal income tax incentives which initially encouraged the growth of investment in non-owner occupied properties.

     Defaults. The claim cycle on private mortgage insurance begins with the insurer’s receipt of notification of a default on an insured loan from the lender. Lenders are required to notify MGIC of defaults within 130 days after the initial default, although most lenders do so earlier. The incidence of default is affected by a variety of factors, including the level of borrower income growth, unemployment, divorce and illness, the level of interest rates and general borrower creditworthiness. Defaults that are not cured result in a claim to MGIC. Defaults may be cured by the borrower bringing current the delinquent loan payments or by a sale of the property and the satisfaction of all amounts due under the mortgage.

     The following table shows the number of primary and pool loans insured in the MGIC Book, including loans insured in bulk transactions and A- and subprime loans, the related number of loans in default and the percentage of loans in default (default rate) as of December 31, 1999-2003:

- 12 -

Default Statistics for the MGIC Book

⁽¹⁾A portion of A-minus and subprime loans is included in the data for flow loans and the remainder is included in the data for bulk loans. Most A-minus and subprime credit loans are written through the bulk channel.

     The default rate for flow loans has generally increased due to an increase in the risk profile of loans insured since 1999 and the continued maturation of MGIC’s insurance in force. The default rate for bulk loans reflects the higher default rate associated with such loans. The default rate for bulk loans is expected to continue to increase. The number of pool insurance loans in force increased at December 31, 1999-2000 as a result of agency pool insurance writings, and the number of pool insurance loans in default at those dates increased due to the increase in pool insurance in force and the aging of the loans in the pools.

- 13 -

     Regions of the United States may experience different default rates due to varying localized economic conditions from year to year. The following table shows the percentage of the MGIC Book’s primary loans in default by MGIC region at the dates indicated:

Default Rates for Primary Insurance By Region*

     Claims. Claims result from defaults which are not cured. Whether a claim results from an uncured default principally depends on the borrower’s equity in the home at the time of default and the borrower’s (or the lender’s) ability to sell the home for an amount sufficient to satisfy all amounts due under the mortgage. Claims are affected by various factors, including local housing prices and employment levels, and interest rates.

     Under the terms of the Master Policy, the lender is required to file a claim for primary insurance with MGIC within 60 days after it has acquired good and marketable title to the underlying property through foreclosure. Depending on the applicable state foreclosure law, at least 12 months transpires from the date of default to payment of a claim on an uncured default.

- 14 -

     Within 60 days after the claim has been filed, MGIC has the option of either (i) paying the coverage percentage specified for that loan, with the insured retaining title to the underlying property and receiving all proceeds from the eventual sale of the property or (ii) paying 100% of the claim amount in exchange for the lender’s conveyance of good and marketable title to the property to MGIC, with MGIC then selling the property for its own account.

     Claim activity is not evenly spread throughout the coverage period of a book of primary business. For prime loans, relatively few claims are received during the first two years following issuance of coverage on a loan. This is followed by a period of rising claims which, based on industry experience, has historically reached its highest level in the third through fifth years after the year of loan origination. Thereafter, the number of claims received has historically declined at a gradual rate, although the rate of decline can be affected by conditions in the economy, including lower housing price appreciation. There can be no assurance that this historical pattern of claims will continue in the future and due in part to the subprime component of loans insured in bulk transactions, MGIC expects that the peak claim period for bulk loans will occur earlier than for prime loans. Moreover, when a loan is refinanced, because the new loan replaces, and is a continuation of, an earlier loan, the pattern of claims frequency for that new loan may be different from the historical pattern of other loans. As of December 31, 2003, 84.6% of the MGIC Book primary insurance in force had been written during 2001 — 2003, although a portion of such insurance arose from the refinancing of earlier originations.

     In addition to the increasing level of claim activity arising from the maturing of the MGIC Book, another important factor affecting MGIC Book losses is the amount of the average claim paid, which is generally referred to as claim severity. The main determinants of claim severity are the amount of the mortgage loan and coverage percentage on the loan. The average claim severity on the MGIC Book primary insurance was $22,925 for 2003 as compared to $20,115 in 2002.

  Loss Reserves

     A significant period of time may elapse between the occurrence of the borrower’s default on a mortgage payment (the event triggering a potential future claim payment by MGIC), the reporting of such default to MGIC and the eventual payment of the claim related to such uncured default. To recognize the liability for unpaid losses related to outstanding reported defaults (known as the default inventory), the Company (similar to other private mortgage insurers) establishes loss reserves, representing the estimated percentage of defaults which will ultimately result in a claim (known as the claim rate), and estimated severity of each claim which will arise from the defaults included in the default inventory. In accordance with industry accounting practices, the Company does not establish loss reserves for future claims on insured loans which are not currently in default.

     The Company also establishes reserves to provide for the estimated costs of settling claims, including legal and other fees, and general expenses of administering the claims settlement process (“loss adjustment expenses”), and for losses and loss adjustment expenses from defaults which have occurred, but which have not yet been reported to the insurer.

- 15 -

     The Company’s reserving process is based upon the assumption that past experience, adjusted for the anticipated effect of current economic conditions and projected future economic trends, provides a reasonable basis for estimating future events. However, estimation of loss reserves is inherently judgmental. Economic conditions that have affected the development of the loss reserves in the past may not necessarily affect development patterns in the future, in either a similar manner or degree.

     For further information about loss reserves, see “Management’s Discussion and Analysis—Results of Consolidated Operations—2003 Compared with 2002” in Item 7 of this Annual Report on Form 10-K and Note 6 to the consolidated financial statements of the Company in Item 8 of this Annual Report on Form 10-K.

C. Other Business and Joint Ventures

     The Company, through subsidiaries, provides various mortgage services for the mortgage finance industry, such as contract underwriting, portfolio retention, secondary marketing of mortgage-related assets and, through its majority-owned Equix Financial Services LLC subsidiary, mortgage loan origination and fulfillment services. The Company’s eMagic.com LLC subsidiary provides an Internet portal through which mortgage originators can access products and services of wholesalers, investors, and vendors necessary to make a home mortgage loan.

     At December 31, 2003, the Company also owned approximately 46% of Credit-Based Asset Servicing and Securitization LLC (“C-BASS”) and approximately 42% of Sherman

- 19 -

Financial Group LLC (“Sherman”), joint ventures with senior management of the joint ventures and Radian Group Inc. Effective January 1, 2003, the Company and Radian Group Inc. each sold 4 percentage points of their respective interest in Sherman to Sherman’s management for cash. For further information about C-BASS and Sherman (which are the principal joint ventures included in the “Income from joint ventures, net of tax” line in the Company’s Consolidated Statement of Operations), see “Management’s Discussion and Analysis—Results of Consolidated Operations—2003 Compared to 2002” in Item 7 of this Annual Report on Form 10-K and Note 8 to the consolidated financial statements of the Company in Item 8 of this Annual Report on Form 10-K.

     In 1997, the Company, through subsidiaries, began insuring second mortgages, including home equity loans. New insurance written on second mortgages in 2002, 2001 and 2000 was approximately $37.8 million, $1.3 billion and $1.1 billion. The Company discontinued writing new second mortgage risk for loans closing after December 31, 2001.

D. Investment Portfolio

  Policy and Strategy

     Approximately 78% of the Company’s long-term investment portfolio is managed by a subsidiary of The Northwestern Mutual Life Insurance Company, although the Company maintains overall control of investment policy and strategy. The Company maintains direct management of the remainder of its investment portfolio.

     The Company’s current policies emphasize preservation of capital, as well as total return. Therefore, the Company’s investment portfolio consists almost entirely of high-quality, fixed-income investments. Liquidity is sought through diversification and investment in publicly traded securities. The Company attempts to maintain a level of liquidity commensurate with its perceived business outlook and the expected timing, direction and degree of changes in interest rates. The Company’s investment policies in effect at December 31, 2003 limited investments in the securities of a single issuer (other than the U.S. government and its agencies) and generally limit the purchase of fixed income securities to those that are rated investment grade by at least one rating agency.

     At December 31, 2003, based on amortized cost, approximately 99.3% of the Company’s total fixed income investment portfolio was invested in securities rated ‘A’ or better, with 84.7% rated ‘AAA’ and 14.1% rated ‘AA,’ in each case by at least one nationally recognized securities rating organization.

     The Company’s investment policies and strategies are subject to change depending upon regulatory, economic and market conditions and the existing or anticipated financial condition and operating requirements, including the tax position, of the Company.

- 20 -

  Investment Operations

     At December 31, 2003, the market value of the Company’s investment portfolio was approximately $5.2 billion. At December 31, 2003, municipal securities represented 74.5% of the market value of the total investment portfolio. Securities due within one year, within one to five years, within five to ten years, and after ten years, represented 3.6%, 21.9%, 23.3% and 51.2%, respectively, of the total book value of the Company’s investment in debt securities. The Company’s net pre-tax investment income was $202.9 million for the year ended December 31, 2003. The Company’s after-tax yield for 2003 was 3.8%, which was lower than the after-tax yield in 2002 of 4.2%.

     For further information concerning investment operations, see Note 4 to the consolidated financial statements of the Company, included in Item 8 of this Annual Report on Form 10-K.

E. Regulation

  Direct Regulation

     The Company and its insurance subsidiaries, including MGIC, are subject to regulation, principally for the protection of policyholders, by the insurance departments of the various states in which each is licensed to do business. The nature and extent of such regulation varies, but generally depends on statutes which delegate regulatory, supervisory and administrative powers to state insurance commissioners.

     In general, such regulation relates, among other things, to licenses to transact business; policy forms; premium rates; insurable loans; annual and other reports on financial condition; the basis upon which assets and liabilities must be stated; requirements regarding contingency reserves equal to 50% of premiums earned; minimum capital levels and adequacy ratios; reinsurance requirements; limitations on the types of investment instruments which may be held in an investment portfolio; the size of risks and limits on coverage of individual risks which may be insured; deposits of securities; limits on dividends payable; and claims handling. Most states also regulate transactions between insurance companies and their parents or affiliates and have restrictions on transactions that have the effect of inducing lenders to place business with the insurer. For a discussion of a February 1, 1999 circular letter from the NYID and a January 31, 2000 letter from the Illinois Department of Insurance, see “The MGIC Book—Types of Product—Pool Insurance.” For a description of limits on dividends payable, see “Management’s Discussion and Analysis—Liquidity and Capital Resources” in Item 7 of this Annual Report on Form 10-K and Note 11 to the consolidated financial statements of the Company in Item 8 of this Annual Report on Form 10-K.

     Mortgage insurance premium rates are also subject to state regulation to protect policyholders against the adverse effects of excessive, inadequate or unfairly discriminatory rates and to encourage competition in the insurance marketplace. Any increase in premium rates must be justified, generally on the basis of the insurer’s loss experience, expenses and future trend analysis. The general mortgage default experience may also be considered. Premium rates are subject to review and challenge by state regulators.

- 21 -

     A number of states generally limit the amount of insurance risk which may be written by a private mortgage insurer to 25 times the insurer’s total policyholders’ reserves, commonly known as the “risk-to-capital” requirement.

     MGIC is required to establish a contingency loss reserve in an amount equal to 50% of earned premiums. Such amounts cannot be withdrawn for a period of 10 years, except under certain circumstances.

     Mortgage insurers are generally single-line companies, restricted to writing residential mortgage insurance business only. Although the Company, as an insurance holding company, is prohibited from engaging in certain transactions with MGIC without submission to and, in some instances, prior approval of applicable insurance departments, the Company is not subject to insurance company regulation on its non-insurance businesses.

     Wisconsin’s insurance regulations generally provide that no person may acquire control of the Company unless the transaction in which control is acquired has been approved by the Office of the Commissioner of Insurance of Wisconsin. The regulations provide for a rebuttable presumption of control when a person owns or has the right to vote more than 10% of the voting securities.

     As the most significant purchasers and sellers of conventional mortgage loans and beneficiaries of private mortgage insurance, Freddie Mac and Fannie Mae impose requirements on private mortgage insurers in order for such insurers to be eligible to insure loans sold to such agencies. These requirements of Freddie Mac and Fannie Mae are subject to change from time to time. Currently, MGIC is an approved mortgage insurer for both Freddie Mac and Fannie Mae. In addition, to the extent Fannie Mae or Freddie Mac assumes default risk for itself that would otherwise be insured, changes current guarantee fee arrangements (including as a result of primary mortgage insurance coverage being restructured as described under “The MGIC Book—Types of Product—Primary Insurance”), allows alternative credit enhancement, alters or liberalizes underwriting guidelines on low down payment mortgages they purchase, or otherwise changes its business practices or processes with respect to such mortgages, private mortgage insurers may be affected.

     Fannie Mae has issued primary mortgage insurance master policy guidelines applicable to MGIC and all other Fannie Mae-approved private mortgage insurers, establishing certain minimum terms of coverage necessary in order for an insurer to be eligible to insure loans purchased by Fannie Mae. The terms of MGIC’s Master Policy comply with these guidelines.

     In December 2003 Standard & Poor’s Rating Services (“S&P”) announced that it lowered MGIC’s financial strength rating to ‘AA’ from ‘AA+’ and the Company’s long-term counterparty credit rating to ‘A’ from ‘A+’ “because of a weakening of MGIC’s operating performance from a very strong to a strong level, as well as rising delinquencies. In addition, the level of risk in MGIC’s book of business is increasing relative to its peers, in part due to the growth in its bulk in-force book, which has grown to about 25% of the total in-force.” S&P said in its announcement that the outlook for MGIC’s and the Company’s ratings was stable. Shortly before S&P’s announcement, Moody’s Investors Service and Fitch Ratings reaffirmed their respective ‘Aa2’ and ‘AA+’ financial strength ratings of MGIC.

     Maintenance of a financial strength rating of at least AA-/Aa3 is critical to a mortgage insurer’s ability to continue to write new business. In assigning financial strength ratings, in addition to considering the adequacy of the mortgage insurer’s capital to withstand extreme loss

- 22 -

scenarios under assumptions determined by the rating agency, rating agencies review a mortgage insurer’s historical and projected operating performance, business outlook, competitive position, management, corporate strategy, and other factors. The rating agency issuing the financial strength rating can withdraw or change its rating at any time.

  Indirect Regulation

     The Company and MGIC are also indirectly, but significantly, impacted by regulations affecting purchasers of mortgage loans, such as Freddie Mac and Fannie Mae, and regulations affecting governmental insurers, such as the FHA and VA, and lenders. Private mortgage insurers, including MGIC, are highly dependent upon federal housing legislation and other laws and regulations to the extent they affect the demand for private mortgage insurance and the housing market generally. From time to time, those laws and regulations have been amended to affect competition from government agencies. Proposals are discussed from time to time by Congress and certain federal agencies to reform or modify the FHA and the Government National Mortgage Association, which securitizes mortgages insured by the FHA.

     Subject to certain exceptions, in general, RESPA prohibits any person from giving or receiving any “thing of value” pursuant to an agreement or understanding to refer settlement services. See “Item 3—Legal Proceedings.”

     The OTS, the OCC, the Federal Reserve Board, and the Federal Deposit Insurance Corporation have uniform guidelines on real estate lending by insured lending institutions under their supervision. The guidelines specify that a residential mortgage loan originated with an LTV of 90% or greater should have appropriate credit enhancement in the form of mortgage insurance or readily marketable collateral, although no depth of coverage percentage is specified in the guidelines.

     Lenders are subject to various laws, including the Home Mortgage Disclosure Act, the Community Reinvestment Act and the Fair Housing Act, and Fannie Mae and Freddie Mac are subject to various laws, including laws relating to government sponsored enterprises, which may impose obligations or create incentives for increased lending to low and moderate income persons, or in targeted areas.

     There can be no assurance that other federal laws and regulations affecting such institutions and entities will not change, or that new legislation or regulations will not be adopted which will adversely affect the private mortgage insurance industry. In this regard, see the last risk factor under “Management’s Discussion and Analysis — Risk Factors” in Item 7 of this Annual Report on Form 10-K.

F. Employees

     At December 31, 2003, the Company and its consolidated subsidiaries had approximately 1,300 full- and part-time employees, of whom approximately 34% were assigned to MGIC’s field offices. The number of employees given above does not include “on-call” employees. The number of “on-call” employees can vary substantially, primarily as a result of changes in demand for contract underwriting services.

- 23 -

G. Website Access

     The Company makes available free of charge through its Internet website its Annual Report on Form 10-K, Quarterly Reports on Form 10-Q, Current Reports on Form 8-K, and amendments to those reports filed or furnished pursuant to Section 13(a) or 15(d) of the Securities Exchange Act of 1934 as soon as reasonably practicable after the Company electronically files such material with the SEC. The address of the Company’s website is www.mgic.com, and such reports and amendments are accessible through the “Investor” link at such address.

Item 2. Properties.

     At December 31, 2003, the Company leased office space in various cities throughout the United States under leases expiring between 2004 and 2008 and which required annual rentals of $3.6 million in 2003.

     The Company owns its headquarters facility and an additional office/warehouse facility, both located in Milwaukee, Wisconsin, which contain an aggregate of approximately 310,000 square feet of space.

Item 3. Legal Proceedings.

     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.

     On October 21, 2003, the appeals that had delayed the finality of the settlement of Downey et. al. v. MGIC, filed in Federal District Court for the Southern District of Georgia in May 2000 (the “RESPA Litigation”), described in Item 3 of the Company’s Annual Report on Form 
10–K for the year ended December 31, 2002 and in Quarterly Reports on Form 10-Q filed with respect to subsequent periods, were dismissed. As a result, the settlement became final on October 21, 2003 and payments were made to borrowers in the class in November 2003. The injunction that was part of the settlement expired on December 31, 2003. The complaint in the case alleged that MGIC violated the Real Estate Settlement Procedures Act by providing agency pool insurance, captive mortgage reinsurance, contract underwriting and other products that were not properly priced, in return for the referral of mortgage insurance.

     On March 27, 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

- 24 -

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 commenced against five other mortgage insurers.

Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations.

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 earned in a year are influenced by:

- 30 -

• Cancellations, which reduce the size of the in force book of insurance that generates premiums. 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.

• New insurance written, which increases the size of the in force book of insurance. New insurance written is affected by many factors, including the volume of low down payment home mortgage originations and competition to provide credit enhancement on those mortgages, including competition from other mortgage insurers and alternatives to mortgage insurance, such as 80-10-10 loans.

• Premium rates, which are affected by the risk characteristics of the loans insured and the percentage of coverage on the loans.

• Premiums ceded to captive mortgage reinsurers and risk sharing arrangements with the GSEs.

• The state of the economy, 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 average claim payment, which is affected by the size of loans insured (higher average loan amounts tend to increase losses incurred), the percentage coverage on insured loans (deeper average coverage tends to increase incurred losses), and housing values, which affect the Company’s ability to mitigate its losses through sales of properties with delinquent mortgages.

• The distribution of claims over the life of a book. Historically, the first years after a loan is originated are a period of relatively low claims, with claims increasing substantially for several years after that and then declining, although persistency and the condition of the economy can affect this pattern.

RESULTS OF CONSOLIDATED OPERATIONS

2003 Compared with 2002

     Net income for 2003 was $493.9 million, compared to $629.2 million in 2002, a decrease of 22%. Diluted earnings per share for 2003 was $4.99 compared with $6.04 in 2002. Adjusted weighted average diluted shares outstanding for the years ended December 31, 2003 and 2002

- 32 -

were 99.0 million and 104.2 million, respectively. As used in this report, the term “Company” means the Company and its consolidated subsidiaries, which does not include less than majority owned joint ventures in which the Company has an equity interest.

New primary insurance written

     The amount of new primary insurance written by MGIC during 2003 was $96.8 billion, compared to $92.5 billion in 2002, an increase of $4.3 billion. New insurance written on a flow basis increased $1.1 billion during 2003 compared to 2002, with refinance volume increasing over last year. New insurance written in the bulk channel increased $3.2 billion during 2003 compared to 2002. A substantial portion of new insurance written in 2003 and 2002 covered refinance loans. Consistent with a forecast made in mid-February 2004 by the Mortgage Bankers Association, which shows a decline in refinance activity in 2004, the Company expects new insurance written in 2004 to decline.

Cancellations and insurance in force

     The $96.8 billion of new primary insurance written during 2003 was offset by the cancellation of $104.2 billion of insurance in force, and resulted in a net decrease of $7.4 billion in primary insurance in force, compared to new primary insurance written of $92.5 billion, the cancellation of $79.4 billion of insurance in force and a net increase of $13.1 billion in primary insurance in force during 2002. Direct primary insurance in force was $189.6 billion at December 31, 2003 compared to $197.0 billion at December 31, 2002.

     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) declined to 47.1% at December 31, 2003 from 56.8% at December 31, 2002. If refinance activity declines in 2004 from its level in 2003, the Company expects that persistency will 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

     New insurance written during 2003 for bulk transactions was $25.7 billion ($6.7 billion, $6.6 billion, $7.3 billion and $5.1 billion for the first through fourth quarters, respectively) compared to $22.5 billion during 2002 (with quarterly volume ranging from $6.6 billion to $4.4 billion). 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

- 33 -

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.

     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 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 December 31 and September 30, 2003 was 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. 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 2003 and 2002 was $862 million and $674 million, respectively. The Company’s direct pool risk in force was $2.9 billion at December 31, 2003 and $2.6 billion at December 31, 2002. The risk amounts are contractual aggregate loss limits and, for the years ended December 31, 2003 and 2002, for $4.9 billion and $3.0 billion, respectively, of risk without such limits, risk is calculated at $192 million and $147 million, respectively, for new risk written and $353 million and $161 million, respectively, for risk in force, representing the estimated amount that would credit enhance these loans to a ‘AA’ level based on a rating agency model.

Net premiums written and earned

     Net premiums written and net premiums earned increased in 2003 primarily as a result of a higher percentage of premiums on products with higher premium rates, principally on insurance written through the bulk channel.

Risk sharing arrangements

     Through September 30, 2003, approximately 53% of the Company’s new insurance written on a flow basis was subject to captive mortgage reinsurance arrangements or risk sharing arrangements with the GSEs; this percentage is comparable to the percentage for the year ended December 31, 2002. (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 subsequent period. Therefore, for 2003, the percentage of new insurance written covered by such arrangements is shown as of the end of the prior 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.

- 34 -

     A substantial portion of the Company’s captive mortgage reinsurance arrangements is structured on an excess of loss basis. At the beginning of the second quarter of 2003 the Company stopped participating in certain excess of loss risk sharing arrangements on terms which are generally present in the market. The captive mortgage reinsurance programs of larger lenders generally are not consistent with the Company’s position. The Company’s position with respect to such risk sharing arrangements resulted in a reduction of business from such lenders and in a decline in the Company’s flow market share in 2003 compared to 2002.

Investment income

     Investment income in 2003 decreased due to a decrease in the average investment yield, offset by an increase in the amortized cost of average invested assets to $4.7 billion for 2003 from $4.2 billion for 2002, an increase of 12%. The portfolio’s average pre-tax investment yield was 4.3% for 2003 and 4.7% for 2002. The portfolio’s average after-tax investment yield was 3.8% for 2003 and 4.2% for 2002. The Company’s net realized gains in 2003 and 2002 resulted primarily from the sale of fixed maturities.

Other revenue

     The increase in other revenue is primarily the result of increased revenue from contract underwriting.

Joint ventures

     The Company’s equity in the earnings from the Sherman and C-BASS joint ventures with Radian Group Inc. (“Radian”) 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 2002 to 2003 is primarily the result of increased equity earnings from Sherman and C-BASS.

     C-BASS, in which the Company and Radian each have an interest of approximately 46%, is a mortgage investment and servicing firm specializing in credit-sensitive single-family residential mortgage assets and residential mortgage-backed securities. C-BASS principally invests in whole loans (including subprime loans) and mezzanine and subordinated residential mortgage-backed securities backed by non-conforming residential mortgage loans. C-BASS’s servicing operations, conducted through its Litton Loan Servicing subsidiary, principally consist of servicing loans on which C-BASS bears the credit risk. C-BASS’s principal sources of revenues during the last three years were gains on securitization and liquidation of mortgage-related assets, servicing fees and net interest income (including accretion on mortgage securities), which revenue items were offset by unrealized losses. In individual periods the relative contribution of these sources to total revenues has varied. C-BASS’s results of operations are affected by the timing of its securitization transactions. Virtually all of C-BASS’s assets do not have readily ascertainable market values and, as a result, their value for financial statement purposes is estimated by the management of C-BASS based on, among other things, valuations provided by financing counterparties. The ultimate value of these assets is the net present value of their future cash flows, which depends on, among other things, the level of losses on the underlying mortgages and prepayment activity by the mortgage borrowers. Market value adjustments could impact C-BASS’s results of operations and the Company’s share of those results.

-35-

for the first through the fourth quarters, respectively. For the year net losses incurred increased by $400 million. This increase was principally the result of a higher number of delinquencies (both bulk and flow), 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 $193 million in net losses paid. The average primary claim paid for 2003 was $22,925 compared to $20,115 for 2002. The Company expects that incurred losses in 2004 will increase over the level of 2003. The Company is not undertaking any obligation to provide an update of this expectation should it subsequently change.

-37-

     Information about the composition of the primary insurance default inventory at December 2003 and 2002 appears in the table below.

*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 increased from 26,676 at December 31, 2002 to 28,135 at December 31, 2003.

     Information about losses paid in 2003 and 2002 appears in the table below.

-38-

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

     At December 31, 2003, 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 increase in underwriting and other expenses is attributable to increases in expenses related to insurance and contract underwriting activity. During 2003 and 2002 the company amortized $29.5 million and $25.9 million, respectively, of deferred insurance policy acquisition costs. See the discussion of deferred policy acquisition costs under “Critical accounting policies”.

     The consolidated insurance operations loss ratio was 56.1% for 2003 compared to 30.9% for 2002. The consolidated insurance operations expense and combined ratios were 14.1% and 70.2%, respectively, for 2003 compared to 14.8% and 45.7% for 2002.

Income taxes

     The effective tax rate was 25.4% in 2003, compared to 29.5% in 2002. 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 2003 principally resulted from a higher percentage of total income before tax being generated from tax-preferenced investments. The Company expects the effective tax rate to be higher in 2004 due to reduced benefits from tax-preferenced investments.

-39-

2002 Compared with 2001

     Net income for 2002 was $629.2 million, compared to $639.1 million in 2001, a decrease of 2%. Diluted earnings per share for 2002 was $6.04 compared with $5.93 in 2001. Adjusted weighted average diluted shares outstanding for the years ended December 31, 2002 and 2001 were 104.2 million and 107.8 million, respectively.

New primary insurance written

     The amount of new primary insurance written by MGIC during 2002 was $92.5 billion, compared to $86.1 billion in 2001, an increase of $6.4 billion. New insurance written in the bulk channel declined $3.2 billion during 2002 compared to 2001. New insurance written on a flow basis increased $9.6 billion during 2002 compared to 2001, with refinance volume approximately equal in both years.

Cancellations and insurance in force

     The $92.5 billion of new primary insurance written during 2002 was offset by the cancellation of $79.4 billion of insurance in force, and resulted in a net increase of $13.1 billion in primary insurance in force, compared to new primary insurance written of $86.1 billion, the cancellation of $62.4 billion of insurance in force and a net increase of $23.7 billion in primary insurance in force during 2001. Direct primary insurance in force was $197.0 billion at December 31, 2002 compared to $183.9 billion at December 31, 2001.

     Cancellation activity increased during 2002 compared to the cancellation levels of 2001 principally due to the lower interest rate environment. MGIC’s persistency rate (percentage of insurance remaining in force from one year prior) declined to 56.8% at December 31, 2002 from 61.0% at December 31, 2001.

Bulk transactions

     New insurance written during 2002 for bulk transactions was $22.5 billion ($6.6 billion, $5.7 billion, $4.4 billion and $5.8 billion for the first through fourth quarters, respectively) compared to $25.7 billion during 2001.

     In the first quarter of 2002, the Company entered into a preliminary agreement providing that new insurance written in 2002 through the bulk channel on Alt A, subprime and certain other loans would be subject to quota share reinsurance of approximately 15% provided by a third party reinsurer. The agreement was terminated on a cutoff basis effective October 1, 2002, relieving both parties of any further obligations.

-40-

Pool insurance

     New pool risk written during 2002 and 2001 was $674 million and $412 million, respectively. The Company’s direct pool risk in force was $2.6 billion at December 31, 2002 and $2.0 billion at December 31, 2001.

Net premiums written and earned

     The increases in net premiums written and earned were primarily a result of the growth in insurance in force and a higher percentage of premiums on products with higher premium rates, principally on insurance written through the bulk channel, offset in part by an increase in ceded premiums.

Risk sharing arrangements

     Premiums ceded in captive mortgage reinsurance arrangements and in risk sharing arrangements with the GSEs increased by $39.0 million in 2002. Through December 31, 2002, approximately 53% of the Company’s new insurance written on a flow basis was subject to such arrangements compared to 50% for the year ended December 31, 2001. (New insurance written through the bulk channel is not subject to such arrangements.)

Investment income

     Investment income increased due to increases in the amortized cost of average invested assets to $4.2 billion for 2002 from $3.7 billion for 2001, offset by a decrease in the investment yield. The portfolio’s average pre-tax investment yield was 4.7% for 2002 and 5.4% for 2001. The portfolio’s average after-tax investment yield was 4.2% for 2002 and 4.6% for the same period in 2001. The Company’s net realized gains in 2002 and 2001 resulted primarily from the sale of fixed maturities.

Other revenue

     The increase in other revenue is primarily the result of increased revenue from contract underwriting.

Joint ventures

     The increase in income from joint ventures from 2001 to 2002 is primarily the result of increased equity earnings from C-BASS and Sherman.

     Total assets of C-BASS at December 31, 2002 and 2001 were approximately $1.754 billion and $1.288 billion, respectively. Total liabilities at December 31, 2002 and 2001 were approximately $1.385 billion and $1.006 billion, respectively, of which approximately $1.110 billion and $0.934 billion, respectively, were debt, virtually all of which matures within one-year or less. The remaining liabilities at those dates were related to interest rate hedging activities or were accrued expenses and other liabilities. For the years ended December 31, 2002 and 2001, revenues of approximately $311 million and $224 million, respectively, and expenses of approximately $173 million and $138 million, respectively, resulted in income before tax of approximately $138 million and $86 million, respectively.

-41-

Losses

     Net losses incurred increased $204.9 million in 2002 after increasing $69.1 million in 2001. On a quarterly basis, net losses incurred were $59.7 million, $64.4 million, $101.1 million and $140.5 million for the first through the fourth quarters, respectively. The increase in 2002 was due to an increase in the primary notice inventory related to bulk default activity and defaults arising from the early development of the 2000 and 2001 flow books of business as well as an increase in losses paid. The average primary claim paid for 2002 was $20,115 compared to $18,607 for 2001.

Underwriting and other expenses

     Interest expense increased primarily due to an increase in debt outstanding offset by lower weighted-average interest rates during 2002 compared to 2001.

     During 2002 and 2001 the Company amortized $25.9 million and $22.2 million, respectively, of deferred insurance policy acquisition costs. The consolidated insurance operations loss ratio was 30.9% for 2002 compared to 15.4% for 2001. The consolidated insurance operations expense and combined ratios were 14.8% and 45.7%, respectively, for 2002 compared to 16.5% and 31.9% for 2001.

Income taxes

     The effective tax rate was 29.5% in 2002, compared to 31.2% in 2001. 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 2002 resulted from a higher percentage of total income before tax being generated from the tax-preferenced investments.

-42-

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 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.

     In December 2003 Standard & Poor’s Rating Services (“S&P”) announced that it lowered MGIC’s financial strength rating to ‘AA’ from ‘AA+’ and the Company’s long-term counterparty credit rating to ‘A’ from ‘A+’ because of a weakening of MGIC’s operating performance from a very strong to a strong level, as well as rising delinquencies. In addition, the level of risk in MGIC’s book of business is increasing relative to its peers, in part due to the growth in its bulk in-force book, which has grown to about 25% of the total in-force.” S&P said in its announcement that the outlook for MGIC’s and the Company’s ratings was stable. Shortly before S&P’s announcement, Moody’s Investors Service (“Moody’s”) and Fitch Ratings reaffirmed their respective ‘Aa2’ and ‘AA+’ financial strength ratings of MGIC.

Financial Condition

     As of December 31, 2003, the Company had $137.7 million of short-term investments with maturities of 90 days or less, and 72% of the investment portfolio was invested in tax-preferenced securities. In addition, at December 31, 2003, 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 December 31, 2003, 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 December 31, 2003, the effective duration of the Company’s fixed income investment portfolio was 5.2 years. This means that for an instantaneous parallel shift in the yield curve of 100 basis points there would be an approximate 5.2% 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.

-43-

     The Company has a $285 million commercial paper program, which is rated ‘A-1’ by S&P and ‘P-1’ by Moody’s. At December 31, 2003 and 2002, the Company had $100.0 million and $177.3 million in commercial paper outstanding with a weighted average interest rate of 1.18% and 1.46%, respectively.

     The Company had a $285 million credit facility available at December 31, 2003 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 maintain policyholders position (which includes MGIC’s surplus and its contingency reserve) of not less than the amount required by Wisconsin insurance regulation. At December 31, 2003, 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 $185.0 million at December 31, 2003.

     The Company had $300 million, 7.5% Senior Notes due in 2005 and $200 million, 6% Senior Notes due in 2007 outstanding at December 31, 2003 and 2002. At December 31, 2003 and 2002, the market value of the outstanding debt was $644.3 million and $721.9 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 December 31, 2003 and 2002 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 during 2003 and 2002 of approximately $3.4 million and $1.8 million, respectively, were 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. As the result of an extraordinary dividend paid by MGIC in March 2003, MGIC cannot pay any dividends without the approval of the Office of the Commissioner of Insurance of the State of Wisconsin (the “OCI”) until March 27, 2004. The first paragraph of Note 11 of the Notes to the Company’s Consolidated Financial Statements included elsewhere in this document discusses the regulations of the OCI governing the payment of dividends without approval of the OCI.

     During 2003, the Company repurchased 2.3 million shares of Common Stock at a cost of $94.1 million. At December 31, 2003, the Company had authority covering the purchase of an additional 7.6 million shares. From mid-1997 through December 31, 2003, the Company has repurchased 23.7 million shares at a cost of $1.2 billion. Funds for the shares repurchased by the

-44-

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 December 31, 2003, 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 $56.1 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 December 31, 2003, 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 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 9.4:1 at December 31, 2003 compared to 9.7:1 at December 31, 2002. The decrease was due to an increase in capital of $0.3 billion, during 2003.

     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. See the last paragraph under “Other Matters” above for a recent announcement by S&P regarding the claims-paying ability rating of MGIC.

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

Contractual Obligations

     At December 31, 2003, the approximate future payments under the contractual obligations of the Company of the type described in the table below are as follows:

     The Company’s long-term debt obligations consist of $300 million, 7.5% Senior Notes due in 2005 and $200 million, 6% Senior Notes due in 2007, as discussed in “Note 5 — short- and long-term debt” to the Company’s consolidated financial statements and under “Liquidity and Capital Resources” above. The Company’s operating lease obligations include operating leases on certain office space, data processing equipment and autos, as discussed in “Note 12 - Leases” to the Company’s consolidated financial statements.

     The Company’s purchase obligations include obligations to purchase computer software, home office furniture and equipment.

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 in estimating the ultimate 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

-46-

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.

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-February 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.

     About 8% of the Company’s risk in force written through the flow channel, and somewhat 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 1.5% of the loans insured by the Company and approximately 6.2% 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 from “strong” to “below average” (or their equivalents) 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.

     A substantial portion of the Company’s captive mortgage reinsurance arrangements are structured on an excess of loss basis. At the beginning of the second quarter of 2003 the Company stopped participating in certain excess of loss risk sharing arrangements on terms which are generally present in the market. The captive mortgage reinsurance programs of larger lenders generally are not consistent with the Company’s position. The Company’s position with respect to such risk sharing arrangements resulted in a reduction of business from such lenders and a decline in the Company’s flow market share in 2003 compared to 2002.

     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. The Company’s top ten customers generated 27.0% of the new primary insurance that it wrote on a flow basis in 1997 compared to 39.5% in 2002 and 33.1% in 2003. The share of Company’s top ten customers declined in 2003 as a result of the Company’s position on captive mortgage reinsurance referred to above.

     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 December 31, 2003 persistency was at 47.1%. 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.

     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. Consistent with a mid-February 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 compared to 2003, the Company expects new insurance written in 2004 will be materially lower than 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 remain a significant percentage of mortgage originations.

     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:

     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 five other mortgage insurers.

     Net premiums written could be adversely affected if a proposed regulation by the Department of Housing and Urban Development under the Real Estate Settlement Procedures Act is adopted.

     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. If mortgage insurance is required on a loan, the package must include any mortgage insurance premium paid at settlement. Although certain state insurance regulations prohibit an insurer’s payment of referral fees, adoption of this regulation by the Department of Housing and Urban Development could adversely affect the Company’s revenues 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 7A. Quantitative and Qualitative Disclosures About Market Risk.

     At December 31, 2003, 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 December 31, 2003, the effective duration of the Company’s fixed income investment portfolio was 5.2 years. This means that for an instantaneous parallel shift in the yield curve of 100 basis points there would be an approximate 5.2% change in the market value of the Company’s fixed income portfolio.

     The Company’s borrowings under its commercial paper program are subject to interest rates that are variable. A discussion of the Company’s interest rate swaps appears in the fifth paragraph of Item 7 of this Annual Report on Form 10-K under “Liquidity and Capital Resources” and such discussion is incorporated by reference.
