Exhibit 99.1

   STATEMENT UNDER OATH OF PRINCIPAL EXECUTIVE OFFICER AND PRINCIPAL FINANCIAL
   OFFICER REGARDING FACTS AND CIRCUMSTANCES RELATING TO EXCHANGE ACT FILINGS

I, Curt S. Culver, state and attest that:

(1) To the best of my knowledge, based upon a review of the covered reports of
MGIC Investment Corporation, and, except as corrected or supplemented in a
subsequent covered report:

o      no covered report contained an untrue statement of a material fact as of
       the end of the period covered by such report (or in the case of a report
       on Form 8-K or definitive proxy materials, as of the date on which it was
       filed); and

o      no covered report omitted to state a material fact necessary to make the
       statements in the covered report, in light of the circumstances under
       which they were made, not misleading as of the end of the period covered
       by such report (or in the case of a report on Form 8-K or definitive
       proxy materials, as of the date on which it was filed).

(2) I have reviewed the contents of this statement with the Company's audit
committee.

(3) In this statement under oath, each of the following, if filed on or before
the date of this statement, is a "covered report":

o      Annual Report on Form 10-K for the year ended December 31, 2001 of MGIC
       Investment Corporation;

o      all reports on Form 10-Q, all reports on Form 8-K and all definitive
       proxy materials of MGIC Investment Corporation filed with the Commission
       subsequent to the filing of the Form 10-K identified above; and

o      any amendments to any of the foregoing.

         /S/ Curt S. Culver
