MGIC INVESTMENT CORPORATION

Through our ~~wholly owned subsidiary,~~ Mortgage Guaranty Insurance Corporation issubsidiary, also referred to as MGIC, we are the leading provider of private mortgage insurance ~~coverage~~ 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, ~~principally~~including to the Federal National Mortgage Association and the Federal Home Loan Mortgage Corporation. In addition to mortgage insurance on first liens, through other subsidiaries, we ~~insure residential second mortgages and~~ provide lenders with various underwriting and other services and products related to home mortgage lending. ~~Mortgage Guaranty Insurance Corporation~~MGIC is licensed to write insurance in all 50 states of the United States, the District of Columbia and Puerto Rico.

We are a Wisconsin corporation. Our principal office is located at MGIC Plaza, 250 East Kilbourn Avenue, Milwaukee, Wisconsin 53202, and our telephone number is 414-347-6480.

We also have ownership interests in less than majority-owned joint ventures, principally Credit-Based Asset Servicing and Securitization LLC, or C-BASS, and Sherman Financial Group LLC, or Sherman. C-BASS is principally engaged in the business of investing in the credit risk of credit sensitive single-family residential mortgages and residential mortgage securities. Sherman is principally engaged in the business of purchasing and servicing delinquent consumer assets such as charged-off credit card loans. Our joint ventures are not consolidated with our company for financial reporting purposes, and are not our subsidiaries.

General

The indenture does not limit the aggregate principal amount of debt securities which we may issue and provides that we may issue debt securities under the indenture from time to time in one or more series. (Section 3.1). The indenture does not limit the amount of other indebtedness or debt securities, other than some secured indebtedness as described below, which we or our subsidiaries may issue. Under the indenture, the terms of the debt securities of any series may differ and we, without the consent of the holders of the debt securities of any series, may reopen a previous series of debt securities and issue additional debt securities of the series or establish additional terms of the series. (Section 3.1).

Unless we otherwise ~~provided~~provide in a prospectus supplement, the debt securities will be our unsecured obligations and will rank equally with all of our other unsecured and unsubordinated indebtedness.

We are a holding company and our principal source of cash is dividends from our Mortgage Guaranty Insurance Corporation subsidiary. Under applicable state insurance law, the amount of cash dividends and other distributions that can be paid from Mortgage Guaranty Insurance Corporation ismay be restricted. ~~These~~We describe these restrictions ~~are described~~ in general terms in the note to our consolidated financial statements that discusses dividend restrictions. ~~This~~We also discuss in this note ~~also discusses~~ the differences between generally accepted accounting principles and statutory insurance accounting principles. One of the insurance law dividend restriction tests is based on statutory ~~policyholders'~~policyholders’ surplus, which is computed under statutory accounting principles by counting items as liabilities that are not counted as liabilities under generally accepted accounting principles. InWe discuss these restrictions and differences in the notes to our consolidated financial statements ~~for the year ended December 31, 1999, the discussion of these restrictions and differences is~~included in ~~note 11. Our~~our most recent Annual Report on Form 10-K, ~~contains our consolidated financial statements and the related notes and~~which is one of the documents ~~incorporated~~we incorporate by reference into this prospectus.

S. bank accounts. ~~Interest~~We will pay interest on debt securities issued in registered form ~~will be payable~~ on any interest payment date to the registered owners of the debt securities at the close of business on the regular record date for the interest payment date. We will name in the prospectus supplement all paying agents we initially designate for the debt securities. We may designate additional 4 paying agents, rescind the designation of any paying agent or approve a change in the office through which any paying agent acts, but we must maintain a paying agent in each place where payments on the debt securities are payable. (Sections 3.7 and 10.2).

Limited Restrictions on Additional ~~Indebtedness.~~Indebtedness. Unless we state otherwise ~~described~~ in athe prospectus supplement, ~~relating to any debt securities,~~and other than as described below under "-“- Limitation on Liens on Stock of Subsidiaries,"” the indenture does not limit our ability to incur debt or give holders of debt securities protection in the event of a sudden and significant decline in our credit quality or a takeover, recapitalization or highly leveraged or similar transaction involving us. Accordingly, we could in the future enter into transactions that could increase the amount of indebtedness outstanding at that time or otherwise affect our capital structure or credit rating. You should refer to the prospectus supplement relating to a particular series of debt securities for information regarding any changes in the events of default described below or covenants contained in the indenture, including any addition of a covenant or other provisions providing event risk or similar protection.

Global Securities ~~The~~

We may issue the debt securities of a series ~~may be issued~~ in whole or in part in the form of one or more global debt securities that we will ~~be deposited~~deposit with a depositary or its nominee ~~identified~~that we identify in the applicable prospectus supplement. ~~The~~

We will describe the specific terms of the depositary arrangement covering debt securities ~~will be described~~ in the prospectus supplement relating to that series. We anticipate that the following provisions will apply to all depositary arrangements.

Upon the issuance of a global security, the depositary for the global security or its nominee will credit to accounts in its book-entry registration and transfer system the principal amounts of the debt securities represented by the global security. ~~These accounts will be designated by the~~The underwriters or agents with respect to the debt securities or ~~by us~~we, if the debt securities are offered and sold directly by ~~us.~~us, will designate these accounts. Only institutions that have accounts with the depositary or its nominee, and persons, who hold beneficial interests through those participants, may own beneficial interests in a global security. Ownership of beneficial interests in a global security will be shown only on, and the transfer of those ownership interests will be effected only through, records maintained by the depositary, its nominee or any participants of the depositary or its nominee, as the case may be. The laws of some states require that ~~certain~~some purchasers of securities take physical delivery of securities in definitive form. These laws may prevent you from transferring your beneficial interest in a global security.

As long as the depositary or its nominee is the registered owner of a global security, the depositary or nominee will be considered the sole owner or holder of the debt securities represented by the global security. Except as described below, owners of beneficial interests in a global security will not be entitled to have debt securities registered in their names and will not be entitled to receive physical delivery of the debt securities in definitive form.

We will make all payments of principal of, any premium and interest on, and any additional amounts with respect to, debt securities issued as global securities to the depositary or its nominee. Neither we nor the trustee, any paying agent or the security registrar assume any responsibility or liability for any aspect of the ~~depositary's~~depositary’s or any ~~participant's~~participant’s records relating to, or for payments made on account of, beneficial interests in a global security.

We expect that the depositary for a series of debt securities or its nominee, upon receipt of any payment with respect to the debt securities, will immediately credit ~~participants'~~participants’ accounts with payments in amounts proportionate to their respective beneficial interest in the principal amount of the global security for the debt securities as shown on the records of the depositary or its nominee. We also expect that payments by participants to owners of beneficial interests in the global security held through 6 participants will be governed by standing instructions and customary practices, as is now the case with securities held for the accounts of customers registered in ~~"street~~“street name,"” and will be the responsibility of the participants.

the depositary notifies us that it is unwilling or unable to continue as depositary for a series of debt securities, or if the depositary is no longer legally qualified to serve in that capacity, and we have not appointed a successor depositary within 90 days of written notice, o

we determine that a series of debt securities will no longer be represented by global securities and we execute and deliver an order to that effect to the trustee, or o

an event of default with respect to a series of debt securities occurs and continues,

then the global securities for that series may be exchanged for registered debt securities in definitive form. (Section 3.5). The definitive debt securities will be registered in the name or names with which the depositary instructs the trustee. We expect that these instructions may be based upon directions the depositary receives from participants with respect to ownership of beneficial interests in global securities.

immediately after the transaction, no event of default occurs and continues; and o

we meet other conditions specified in the indenture. (Section 8.1).

Modification and Waiver

We and the trustee may modify and amend the indenture with the consent of the holders of a majority in aggregate principal amount of the outstanding debt securities of each affected series. However, without the consent of each holder, we cannot modify or amend the indenture in a way that would: o

(Sections 5.8 and 5.13).

default in the payment of principal or any premium; o

default in the deposit of any sinking fund payment; o

default in the performance of any other covenant in the indenture that continues for 60 days after written notice of such default; o

(Section 6.2). If the holders provide this security or indemnity, then the holders of a majority in principal amount of the outstanding debt securities of a series may direct the time, method and place of conducting any proceeding for any remedy available to the trustee, or exercising any trust or powers conferred on the trustee with respect to the debt securities of that series. (Section 5.12).

No holder of a debt security may bring any lawsuit or other proceeding with respect to the indenture or for any remedy under the indenture unless the holder first gives the trustee written notice of a continuing event of default, the holders of at least 25% in principal amount of the outstanding debt securities of the series in default give the trustee a written request to bring the proceeding and offer the trustee reasonable security or indemnity and the trustee fails to institute the proceeding for 60 days after the written request and has not received from holders of a majority in principal amount of the outstanding debt securities of the series in default a direction inconsistent with that request. (Section 5.7). However, the holder of any debt security has the absolute right to receive payment of the principal of and any premium or interest on the debt security on or after the stated due dates and to take any action to enforce any payment of principal of and any interest on the debt security. (Section 5.8).

Discharge, Defeasance and Covenant Defeasance

We may discharge some obligations to holders of any series of debt securities that have not already been delivered to the trustee for cancellation and that either have become due and payable, will become due and payable within one year or are scheduled for redemption within one year by depositing with the trustee, in trust, funds in U. S. dollars or in the foreign currency in which the debt securities are payable in an amount sufficient to pay the principal and any premium, interest and additional amounts on the debt securities to the date of deposit, if the debt securities have become due and payable, or to the maturity date, as the case may be. (Section 4.1).

Unless we state in the applicable prospectus supplement ~~states~~ that the following provisions do not apply to the debt securities of that series, we may elect either: o

to defease and be discharged from ~~any and~~ all obligations with respect to the debt securities, except for, among other things, the obligation to pay additional amounts, if any, upon the occurrence of some events of taxation, assessment or governmental charge with respect to payments on the debt securities and other obligations to register the transfer or exchange of the debt securities, to replace temporary or mutilated, destroyed, lost or stolen debt securities, to maintain an office or agency with respect to the debt securities and to hold moneys for payment in trust, also referred to as defeasance; or o

to be released from our obligations under the indenture with respect to the debt securities under some covenants as ~~described~~we describe in the prospectus supplement, and our failure to comply with these obligations will not constitute an event of default with respect to the debt securities, also referred to as covenant defeasance. (Section 4.2). 10

Defeasance or covenant defeasance is conditioned on our irrevocable deposit with the trustee, in trust, of an amount in cash or government securities, or both, sufficient to pay the principal of, any premium and interest on, and any additional amounts with respect to, the debt securities on the scheduled due dates. (Section 4.2).

the applicable defeasance or covenant defeasance does not result in a breach or violation of, or constitute a default under, the indenture or any other material agreement or instrument to which we are a party or by which we are bound; o

no event of default, or event which with notice or lapse of time would become an event of default, has occurred and continues on the date the trust is established and, with respect to defeasance only, at any time during the period ending on the 123rd day after that date; and o

we have delivered to the trustee an opinion of counsel to the effect that the holders of the debt securities will not recognize income, gain or loss for U. S. federal income tax purposes as a result of the defeasance or covenant defeasance and will be subject to U. S. federal income tax on the same amounts, in the same manner and at the same times as would have been the case if the defeasance or covenant defeasance had not occurred. This opinion, in the case of defeasance, must refer to and be based upon a letter ruling we have received from the Internal Revenue Service, a revenue ruling published by the Internal Revenue Service or a change in applicable U. S. federal income tax law occurring after the date of the indenture. (Section 4.2).

Governing Law

The indenture and the debt securities are governed by and will be interpreted under the laws of the State of New York. (Section 1.13).

Information Concerning the Trustee

Subject to the provisions of the Trust Indenture Act of 1939, the trustee is under no obligation to exercise any of the powers vested in it by the indenture at the request of any holder of debt securities unless the holder offers the trustee reasonable indemnity against the costs, expenses and liabilities which might result. The trustee is not required to expend or risk its own funds or otherwise incur personal financial liability in performing its duties if the trustee reasonably believes that it is not reasonably assured of repayment or adequate indemnity. (Section 6.2).

The initial public offering price, discounts or concessions allowed or reallowed or~~commissions paid to ~~dealers may be changed from time to time. We may offer the debt securities in one or more transactions at a fixed price or prices, which~~agents.

In addition, we may ~~change, at market prices prevailing at~~enter into derivative transactions with third parties, or sell securities not covered by this prospectus to third parties in privately negotiated transactions. If the ~~time~~applicable prospectus supplement indicates, in connection with those derivatives, the third parties may sell securities covered by this prospectus and the applicable prospectus supplement, including in short sale transactions. If so, the third parties may use securities pledged by us or borrowed from us or others to settle those sales or to close out any related open borrowings of stock, and may use securities received from us in settlement of those derivatives to close out any related open borrowings of stock. The third parties in such sale ~~at prices related to the prevailing market prices or at negotiated prices. We may authorize agents to solicit offers to purchase debt securities from time to time.

Any agent may be deemed to be an underwriter, as that term is defined in the Securities Act of 1933, of the debt~~other securities so offered ~~and sold.

Representatives of the underwriters through whom the offered securities are sold for public offering and sale may engage in over-allotment, stabilizing transactions, syndicate short covering transactions and penalty bids in accordance with Regulation M under the Securities Exchange Act of 1934. Over-allotment involves syndicate sales in excess of the offering size, which creates a syndicate short position. Stabilizing transactions permit bids to purchase the offered securities so long as the stabilizing bids do not exceed a specified maximum. Syndicate covering transactions involve purchases of the offered securities in the open market after the distribution has been completed in order to cover syndicate short positions. Penalty bids permit the representative of the underwriters to reclaim a selling concession from a syndicate member when the offered securities originally sold by such syndicate member are purchased in a syndicate covering transaction to cover syndicate short positions. Such stabilizing transactions, syndicate covering transactions and penalty bids may cause the price of the offered securities to be higher than it would otherwise be in the absence of such transactions. These transactions may be effected on a national securities exchange and, if commenced, may be discontinued at any time.

Some or all of the securities that we offer though this prospectus may be new issues of securities with no established trading market. Any underwriters to whom we sell our securities for public offering and sale may make a market in those securities, but they will not be obligated to do so and they may discontinue any market making at any time without notice. Accordingly, we cannot assure you of the liquidity of, or continued trading markets for, any securities that we offer.

Remarketing Arrangements

Offered securities may also be offered and sold, if so indicated in the applicable prospectus supplement, in connection with a remarketing upon their purchase, in accordance with a redemption or repayment pursuant to their terms, or otherwise, by one or more remarketing firms, acting as principals for their own accounts or as agents for us. Any remarketing firm will be identified and the terms of its agreements, if any, with us and its compensation will be described in the ~~related~~applicable prospectus supplement. ~~Agents, underwriters and dealers~~Remarketing firms may be ~~entitled~~deemed to be underwriters, as that term is defined in the Securities Act of 1933, in connection with the securities remarketed.

Delayed Delivery Arrangements

If we so indicate in the prospectus supplement, we may authorize agents, underwriters or dealers to solicit offers from certain types of institutions to purchase securities from us at the public offering price under delayed delivery contracts. These contracts would provide for payment and delivery on a specified date in the future. The contracts would be subject only to those conditions described in the prospectus supplement. The prospectus supplement will describe the commission payable for solicitation of those contracts.

Each series of debt securities will be a new issue and will have no established trading market. We may elect to list any series of debt securities on an exchange but, unless otherwise stated in the applicable prospectus supplement, we are not required to do so.

Item 15. Indemnification of ~~Officers~~Directors and ~~Directors.~~Officers.

Pursuant to the Wisconsin Business Corporation Law and the ~~Registrant's~~Registrant’s Amended and Restated Bylaws, directors and officers of the Registrant are entitled to mandatory indemnification from the Registrant against certain liabilities and expenses (1) to the extent such officers or directors are successful in the defense of a proceeding and (2) in proceedings in which the director or officer is not successful in defense thereof, unless (in the latter case only) it is determined that the director or officer breached or failed to perform his or her duties to the Registrant and such breach or failure constituted: (a) a willful failure to deal fairly with the Registrant or its shareholders in connection with a matter in which the director of officer had a material conflict of interest; (b) a violation of the criminal law unless the director or officer had reasonable cause to believe his or her conduct was lawful or had no reasonable cause to believe his or her conduct was unlawful; (c) a transaction from which the director or officer derived an improper personal profit; or (d) willful misconduct. The Wisconsin Business Corporation law specifically states that it is the public policy of Wisconsin to require or permit indemnification, allowance of expenses and insurance in connection with a proceeding involving securities regulation, as described therein, to the extent required or permitted as described above.

Expenses for the defense of any action for which indemnification may be available may be advanced by the Registrant under certain circumstances.

The indemnification provided by the Wisconsin Business Corporation Law and the ~~Registrant's~~Registrant’s Amended and Restated Bylaws is not exclusive of any other rights to which a director or officer may be entitled. The Registrant also maintains a liability insurance policy for its directors and officers as permitted by Wisconsin law which may extend to, among other things, liability arising under the Securities Act of 1933. ~~II-1~~

Item 16. ~~Exhibits.~~Exhibits and Financial Statement Schedules.

The exhibits listed in the accompanying Exhibit Index are filed ~~herewith~~ or incorporated by reference herein are specified on the Exhibit Index included herein. Item 17. Undertakings (a) The undersigned registrant hereby undertakes: (1) To file, during any period in which offers or sales are being made, a post-effective amendment to this registration statement: (i) To include any prospectus required by Section 10(a)(3) of the Securities Act of 1933; (ii) To reflect in the prospectus any facts or events arising after the effective date of the registration statement (or the most recent post-effective amendment thereof) which, individually or in the aggregate, represent a fundamental change in the information set forth in the registration statement. Notwithstanding the foregoing, any increase or decrease in volume of securities offered (if the total dollar value of securities offered would not exceed that which was registered) and any deviation from the low or high end of the estimated maximum offering range may be reflected in the form of prospectus filed with the Commission pursuant to Rule 424(b) if, in the aggregate, the changes in volume and price represent no more than a 20 percent change in the maximum aggregate offering price set forth in the "Calculation of Registration Fee" table in the effective registration statement; (iii) To include any material information with respect to the plan of distribution not previously disclosed in the registration statement or any material change to such information in the registration statement; provided, however, that paragraphs (a)(i) and (a)(ii) do not apply if the information required to be included in a post-effective amendment by those paragraphs is contained in periodic reports filed with or furnished to the Commission by the registrant pursuant to Section 13 or 15(d) of the Securities Exchange Act of 1934 that are incorporated by reference in the registration statement. (2) That, for the purpose of determining any liability under the Securities Act of 1933, each such post-effective amendment shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof. (3) To remove from registration by means of a post-effective amendment any of the securities being registered, which remain unsold at the termination of the offering. (b) The undersigned registrant hereby undertakes that, for purposes of determining any liability under the Securities Act of 1933, each filing of the Registrant's annual report pursuant to Section 13(a) or 15(d) of the Securities Exchange Act of 1934 that is incorporated by reference in the registration statement shall be deemed to be a new registration statement relating to the securities offered II-2 therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof. (c) The undersigned registrant hereby undertakes that: (1) For purposes of determining any liability under the Securities Act of 1933, the information omitted from the form of prospectus filed as part of this registration statement in reliance upon Rule 430A and contained in a form of prospectus filed by the registrant pursuant to Rule 424(b)(1) or (4) or 497(h) under the Securities Act of 1933 shall be deemed to be part of this registration statement as of the time it was declared effective; and (2) For the purpose of determining any liability under the Securities Act of 1933, each post-effective amendment that contains a form of prospectus shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof. (d) Insofar as indemnification for liabilities arising under the Securities Act of 1933 may be permitted to directors, officers or controlling persons of the registrant pursuant to the provisions set forth or described in Registration Statement.

Item 15 of this registration statement, or otherwise, the registrant has been informed that in the opinion of the Securities and Exchange Commission such indemnification is against public policy as expressed in the Securities Act of 1933 and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the registrant of expenses incurred or paid by a director, officer or controlling person of the registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, the registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Securities Act of 1933 and will be governed by the final adjudication of such issue.
