                 MGIC INVESTMENT CORPORATION AND SUBSIDIARIES
                  NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                                March 31, 1998
                                  (Unaudited)


Note 1 - Basis of presentation

      The   accompanying   unaudited  consolidated   financial
statements of MGIC Investment Corporation (the "Company")  and
its wholly-owned subsidiaries have been prepared in accordance
with  the instructions to Form 10-Q and do not include all  of
the  other  information and disclosures required by  generally
accepted  accounting principles.  These statements  should  be
read in conjunction with the consolidated financial statements
and  notes  thereto  for  the year  ended  December  31,  1997
included in the Company's Annual Report on Form 10-K for  that
year.

     The  accompanying consolidated financial statements  have
not been audited by independent accountants in accordance with
generally  accepted auditing standards, but in the opinion  of
management  such financial statements include all adjustments,
consisting  only  of normal recurring accruals,  necessary  to
summarize fairly the Company's financial position and  results
of  operations.  The  results  of  operations  for  the  three
months  ended  March  31, 1998 may not be  indicative  of  the
results that may be expected for the year ending December  31,
1998.

Note 2 - Notes payable

     During 1997, the Company repurchased 4,655,985 shares  of
its outstanding common stock from a financial intermediary  at
a cost of approximately $248 million.  Funds to repurchase the
shares  were primarily provided by borrowings under  a  credit
facility  evidenced  by notes payable.  The  weighted  average
interest  rate  on the notes at March 31, 1998 was  5.92%  per
annum.  The interest rate on borrowings under the facility  is
variable.

     The  credit facility provides for up to $250  million  of
availability  which  decreases  by  $25  million   each   year
beginning   June  20,  1998  through  June  20,   2001.    Any
outstanding borrowings under the facility mature on  June  20,
2002.   The Company has the option, on notice to the  lenders,
to  prepay  any  borrowings subject to certain provisions.  At
March   31,  1998  outstanding  borrowings  under  the  credit
facility were generally for terms of less than one year.

     Under the terms of the credit facility, the Company  must
maintain  shareholders' equity of at least  $900  million  and
MGIC  must maintain a claims paying ability rating of  AA-  or
better  with Standard & Poor's Corporation ("S&P").  At  March
31,  1998,  the  Company had shareholders'  equity  of  $1,578
million  and  MGIC had a claims paying ability rating  of  AA+
from S&P.

     During  1998  MGIC guaranteed one half of a  $50  million
credit   facility  for  C-BASS,  a  48%  owned  unconsolidated
subsidiary.  The facility matures in January 1999.

Note 3 - Contingencies

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

     In addition to the litigation referred to above, Mortgage
Guaranty  Insurance Corporation ("MGIC") is a defendant  in  a
lawsuit  commenced by a borrower  challenging the necessity of
maintaining   mortgage  insurance  in  certain  circumstances,
primarily  when  the loan-to-value ratio  is  below  80%.  The
lawsuit  purports  to  be brought on  behalf  of  a  class  of
borrowers.  This case appears to be based to some degree  upon
guidelines   issued   by  the  Federal  Home   Loan   Mortgage
Corporation  or  the Federal National Mortgage Association  to
their  respective mortgage servicers under which the  mortgage
servicers  may be required in certain circumstances to  cancel
borrower-purchased insurance upon the borrower's request.  The
plaintiff alleges that MGIC has a common law duty to inform  a
borrower  that  the  insurance  may  be  cancelled  in   these
circumstances. The relief sought is equitable relief  as  well
as  the  return  of  premiums paid  after  the  insurance  was
cancellable  under  the  applicable guidelines.   The  Company
believes that MGIC has a meritorious defense to this action in
that, in the absence of a specific statute (no statutory  duty
other than under a general consumer fraud statute is alleged),
there  appears to be no legal authority requiring  a  mortgage
insurer  to inform a borrower that insurance may be cancelled.
Summary judgment was granted to MGIC in another case involving
similar  issues.   Similar  cases  are  pending  against other
mortgage  insurers,   mortgage   lenders   and  mortgage  loan
servicers.

Note 4 - Shareholders' equity

     On  June 2, 1997 the Company effected a two-for-one stock
split  of  the Company's common stock in the form  of  a  100%
stock  dividend.  The  prior year share, per share and certain
equity   amounts  set  forth  in  the  accompanying  financial
statements have been adjusted to take into account  the  stock
split.

                                    PAGE 7

Note 5 - Earnings per share

    The Company's basic and diluted earnings per share ("EPS")
have been calculated in accordance with Statement of Financial
Accounting Standards No. 128, Earnings Per Share ("SFAS 128").
The  following  is  a  reconciliation of the  weighted-average
number of shares used for basic EPS and diluted EPS.

                                  Three Months Ended March 31,

                                      (Shares in thousands)

 Weighted-average shares - Basic EPS   113,989      118,108
 Common stock equivalents                1,752        1,215

                                       =======      =======  

     Earnings per share for 1997 has been restated to  reflect
the provisions of SFAS 128.  Previously reported EPS for 1997,
after  adjustment  for the stock split,  equaled  diluted  EPS
under SFAS 128.

Note 6 - New accounting standards

     Effective January 1, 1998, the Company adopted  Statement
of   Financial   Accounting  Standards  No.   130,   Reporting
Comprehensive    Income   ("SFAS   130").     The    statement
establishes  standards  for  the  reporting  and  display   of
comprehensive  income and its components in  annual  financial
statements.   The  Company's total  comprehensive  income,  as
calculated per SFAS 130,  was as follows:

                                  Three Months Ended March 31,
                                  ----------------------------

    Other comprehensive loss           (10,792)    (22,851)
                                      --------    ---------
      Total comprehensive income      $ 83,255    $ 49,585
                                      ========    ========

     The  difference  between the Company's  net   income  and
total  comprehensive income for the three months  ended  March
31,  1998  and  1997  is  primarily the change  in  unrealized
appreciation on  investments, net of tax.

                                    PAGE 8

Note 7 - Subsequent events

      On  May  7,  1998,  the  Company's  Board  of  Directors
authorized  the  repurchase of shares of the Company's  common
stock  with an aggregate purchase price of up to $250 million.
The  Company's previous $250 million stock repurchase  program
was  completed during 1997.  The Company expects to  fund  the
repurchase  program  through a bank loan facility,  which  the
Company  is  in  the process of arranging, and from  operating
cash flow.

    At the Company's May 7, 1998 annual shareholders' meeting,
shareholders approved an increase in the number of  authorized
shares  of common stock from 150 million to 300 million shares
and approved a class of preferred stock of 10 million shares.

ITEM 2.   MANAGEMENT'S DISCUSSION AND ANALYSIS OF
          FINANCIAL CONDITION AND RESULTS OF OPERATIONS


Results of Consolidated Operations

  Three Months Ended March 31, 1998 Compared With Three Months
  Ended March 31, 1997

     Net income for the three months ended March 31, 1998  was
$94.0  million, compared to $72.4 million for the same  period
of  1997,  an  increase of 30%.  After giving effect   to  the
Company's  two-for-one  stock split, effective June  2,  1997,
diluted  earnings per share for the three months  ended  March
31,  1998 was $0.81 compared to $0.61 in the same period  last
year,  an  increase  of  33%.   See  notes  4  and  5  to  the
consolidated financial statements.

     The  amount of new primary insurance written by  Mortgage
Guaranty  Insurance  Corporation  ("MGIC")  during  the  three
months ended March 31, 1998 was $8.5 billion, compared to $6.5
billion  in  the  same  period of 1997.  Refinancing  activity
accounted  for  35% of new primary insurance  written  in  the
first quarter of 1998, compared to 17% in the first quarter of
1997.

     New  insurance  written for the  first  quarter  of  1998
reflected  an  increase in the usage of  the  monthly  premium
product  to  95%  of new insurance written  from  92%  of  new
insurance  written in the first quarter of 1997. New insurance
written for adjustable-rate mortgages decreased to 13% of  new
insurance written in the first quarter of 1998 from 26% of new
insurance written in the same period of 1997.  Also, mortgages
with  loan-to-value ratios in excess of 90% but not more  than
95%  decreased to 34% of new insurance written  in  the  first
quarter of 1998 from 42% of new insurance written in the  same
period of 1997.

     The  $8.5 billion of new primary insurance written during
the  first  quarter of 1998 was offset by the cancellation  of
$8.7  billion  of insurance in force, and resulted  in  a  net
decrease  of  $.2  billion  in  primary  insurance  in  force,
compared to new primary insurance written of $6.5 billion, the
cancellation  of  $5.1  billion, and a net  increase  of  $1.4
billion  in  insurance in force during the  first  quarter  of
1997.    Direct   primary   insurance   in  force  was  $138.3
billion  at  March  31,  1998 compared to  $138.5  billion  at
December  31, 1997 and $132.8 billion at March 31,  1997.   In
addition to providing  primary insurance coverage, the Company
also  insures pools of mortgage loans.  New pool risk  written
during the three months ended March 31, 1998 was $144 million,
which  was virtually all agency pool insurance.  The Company's
direct pool risk in force at March 31, 1998 was $730.7 million
compared  to $261.3 million at March 31, 1997 and is  expected
to  increase  during  the remainder of 1998  as  a  result  of
outstanding  commitments  to  write  additional  agency   pool
insurance.

                                    PAGE 10

     Cancellation activity increased during 1997 and the first
quarter of 1998 due to favorable mortgage interest rates which
resulted   in   a  decrease  in  the  MGIC  persistency   rate
(percentage  of  insurance  remaining in force from  one  year
prior)   to  78.4% at March 31, 1998 from 82.7% at  March  31,
1997.   Cancellation activity could increase  due  to  factors
other  than  refinances and home sales if proposed legislation
regarding cancellation of mortgage insurance is enacted.

     Net premiums written were $176.5 million during the first
quarter  of 1998, compared to $155.6 million during the  first
quarter of 1997, an increase of 13%. Net premiums earned  were
$189.8  million for the first quarter of 1998, an increase  of
11%  over the $170.3 million for the same period in 1997.  The
increases  were primarily a result of the growth in  insurance
in force since March 31, 1997 and renewal premiums on mortgage
loans with deeper coverages.

     Investment income for the first quarter of 1998 was $34.4
million,  an  increase of 17% over the $29.5  million  in  the
first quarter of 1997.  This increase was primarily the result
of  an  increase  in  the amortized cost of  average  invested
assets to $2.4 billion for the first quarter of 1998 from $2.0
billion for the first quarter of 1997, an increase of 17%. The
portfolio's average pre-tax investment yield was 5.8% for  the
first  quarter of 1998 and 5.9% for the same period  in  1997.
The  portfolio's average after-tax investment yield  was  4.9%
for the first quarter of 1998 and 5.0% for the same period  in
1997.  The Company realized gains of $10.3 million during  the
three months ended March 31, 1998 resulting primarily from the
sale  of equity securities compared to minimal realized  gains
on investments during the same period in 1997.

     Other  revenue was $9.5 million for the first quarter  of
1998  compared  to $5.2 million for the same period  in  1997.
The increase is primarily the result of $1.9 million of equity
earnings from C-BASS, the Company's joint venture with Enhance
Financial  Services  Group Inc. and an increase  in  fee-based
services for underwriting.

     Net  losses incurred decreased 6% to $59.4 million during
the  first quarter of 1998 from $63.2 million during the first
quarter of 1997.  Such decrease was primarily attributed to  a
decrease in the primary insurance notice inventory during  the
first  quarter  as  compared to an increase   in  the  primary
insurance  notice  inventory during the comparable  period  of
1997,  along with improvements in certain high-cost geographic
regions.  At March 31, 1998, 59% of MGIC's insurance in  force
was  written during the preceding thirteen quarters,  compared
to  63%  at March 31, 1997. 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  for  refinance  loans may  be  different  from  the
historical pattern of other loans.

     Underwriting  and  other  expenses  increased   to  $45.2
million in the first quarter of 1998 from $38.2 million in the
first  quarter of 1997, an increase of 18%. This increase  was
primarily due to an increase in expenses associated  with  the
fee-based services for underwriting and an increase in premium
tax due to higher premiums written.
 
                                    PAGE 11

     Interest  expense increased to $3.6 million in the  first
quarter  of  1998 from $.3 million during the same  period  in
1997.  Interest expense in the current period is the result of
debt  incurred to fund the stock repurchase program.  Interest
expense  for  the  first quarter of 1997  represents  interest
prior  to  the  repayment in January  1997  of  the  mortgages
payable. See note 2 to the consolidated financial statements.

    The consolidated insurance operations loss ratio was 31.3%
for  the first quarter of 1998 compared to 37.1% for the first
quarter of 1997. The consolidated insurance operations expense
and  combined  ratios were 19.9% and 51.2%, respectively,  for
the  first quarter of 1998 compared to 21.1% and 58.2% for the
first quarter of 1997.

     The effective tax rate was 30.9% in the first quarter  of
1998,  compared to 30.3% in the first quarter of 1997.  During
both  periods, the effective tax rate was below the  statutory
rate  of  35%,  reflecting  the  benefits  of  tax-preferenced
investment  income.  The higher effective  tax  rate  in  1998
resulted  from a lower percentage of total income  before  tax
being generated from tax-preferenced investments.

Liquidity and Capital Resources

     The  Company's  consolidated  sources  of  funds  consist
primarily  of  premiums  written and investment  income.   The
Company   generated   positive  cash  flows   from   operating
activities of $132.5 million for the three months ended  March
31,  1998,  as  shown on the Consolidated  Statement  of  Cash
Flows.   Funds are applied primarily to the payment of  claims
and   expenses.   The  Company's  business  does  not  require
significant capital expenditures on an ongoing basis. 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.

     Consolidated total investments were $2.5 billion at March
31,  1998, compared to $2.4 billion at December 31,  1997,  an
increase  of  5%.  This increase is due primarily to  positive
cash  flow from operations.  The investment portfolio includes
unrealized gains on securities marked to market at  March  31,
1998  and  December 31, 1997  of  $112.6 million   and  $129.2
million, respectively.  As of March 31, 1998, the Company  had
$222.6 million  of  short-term investments with maturities  of
90  days  or less.   In addition, at March 31, 1998, based  on
amortized  cost, the Company's total investments,  which  were
primarily  comprised of fixed maturities,  were  approximately
98%  invested  in  "A"  rated  and above,  readily  marketable
securities, concentrated in maturities of less than 15 years.

     Consolidated loss reserves increased 3% to $617.7 million
at  March  31, 1998 from $598.7 million at December 31,  1997.
Consistent  with  industry practices,  the  Company  does  not
establish  loss  reserves for future claims on  insured  loans
which are not currently in default.

                                    PAGE 12

     Consolidated  unearned premiums decreased  $14.6  million
from $198.3 million at December 31, 1997 to $183.7 million  at
March  31, 1998, primarily reflecting the continued high level
of  monthly  premium policies written, for which there  is  no
unearned   premium.  Reinsurance  recoverable   on    unearned
premiums  decreased  $1.3 million to $7.9 million at March 31,
1998  from  $9.2  million  at  December  31,  1997,  primarily
reflecting the reduction in unearned premiums.

      Consolidated  shareholders'  equity  increased  to  $1.6
billion  at March 31, 1998, from $1.5 billion at December  31,
1997,  an  increase of 6%.  This increase consisted  of  $94.0
million  of net income during the first three months  of  1998
and $10.7 million from the reissuance of treasury stock offset
by  a decrease in net unrealized gains on investments of $10.8
million, net of tax, and dividends declared of $2.8 million.

    MGIC is the principal insurance subsidiary of the Company.
MGIC's  risk-to-capital ratio was 15.1:1  at  March  31,  1998
compared to 15.7:1 at December 31, 1997.  The decrease was due
to  MGIC's increased policyholders' reserves, partially offset
by  the net additional risk in force of $77.1 million, net  of
reinsurance, during the first three months of 1998.

    The Company's combined insurance risk-to-capital ratio was
15.7:1  at March 31, 1998, compared to 16.4:1 at December  31,
1997.   The  decrease was due to the same reasons as described
above.

     See  note 7 for discussion regarding the Company's  stock
repurchase program.

Year 2000  Compliance

     Almost  all of the Company's computer systems,  including
all  of the systems which are integral to its business, either
have  been  originally developed to be Year 2000 compliant  or
have  been  reprogrammed.  The Company plans to reprogram  the
remaining  systems and to complete tests of  all  systems  for
Year  2000 compliance by the end of 1998.  All costs  incurred
through  the first quarter of 1998 for systems for  Year  2000
compliance have been expensed and were immaterial.  The  costs
of  the remaining reprogramming and testing are expected to be
immaterial.   Some of the Company's computer systems  integral
to  its  business  interface with computer  systems  of  third
parties.  Virtually all transactions with systems operated  by
third  parties involve nationally recognized service  bureaus,
Fannie Mae, Freddie Mac or other companies that were among the
top  50  mortgage servicers in 1997.  The Company is  assuming
that  these third parties will successfully address Year  2000
compliance for their own systems and is planning to work  with
many  of these third parties in 1998 to coordinate testing  of
Year  2000  system interfaces.  As a result, the Company  does
not  anticipate  Year 2000 compliance arising from  interfaces
with  third-party systems will have a material impact  on  its
operations.

ITEM 3.  QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT
         MARKET RISK

    At March 31, 1998, the Company had no derivative financial
instruments  in its investment portfolio.   The Company places
its  investments in instruments that meet high credit  quality
standards,  as  specified in the Company's  investment  policy
guidelines;  the  policy  also limits  the  amount  of  credit
exposure to any one issue, issuer and type of instrument.   At
March   31,  1998,  the  average  duration  of  the  Company's
investment  portfolio  was 5.7 years.   The  effect  of  a  1%
increase/decrease in market interest rates would result  in  a
5.7%   decrease/increase  in  the  value  of   the   Company's
investment portfolio.

     The  Company's borrowings under the credit  facility  are
subject  to  an  interest rate that is variable.   Changes  in
market  interest rates would have minimal impact on the  value
of the note payable.  See note 2 to the consolidated financial
statements.

SAFE HARBOR STATEMENT

     The following is a "Safe Harbor" Statement under  the
Private  Securities Litigation Reform Act of  1995,  which
applies to all statements in this Form 10-Q, which are not
historical  facts  and  to all oral  statements  that  the
Company may make from time to time relating thereto  which
are not historical facts (such written and oral statements
are herein referred to as "forward looking statements"):

    Actual  results  may  differ  materially   from  those
    contemplated by the forward looking statements.  These
    forward   looking   statements   involve   risks   and
    uncertainties,  including  but  not  limited  to,  the
    following risks:
     
        -     that  demand  for housing generally  or  in
        MGIC's  market segment may be adversely  affected
        by  changes  in interest rates, adverse  economic
        conditions, or other reasons;

        -     that  government housing policy may change,
        including    changes    in    Federal     Housing
        Administration ("FHA") loan limits,  and  changes
        in    the   statutory   charters   and   coverage
        requirements of Freddie Mac and Fannie Mae;  that
        MGIC's  market share of new insurance written  or
        the  amount  of  new  insurance  written  may  be
        adversely   affected  as  a  result  of   factors
        affecting  housing  demand,  government   housing
        policy  and Freddie Mac and Fannie Mae  discussed
        above; or as a result of underwriting changes  by
        the  Company;  actions  taken  by  the  Company's
        competitors,    including   their    underwriting
        criteria,  pricing or products offered; decisions
        by  lenders  to originate low down payment  loans
        using   substitutes   for   mortgage   insurance,
        including   self-insurance,  or  to  the   extent
        legally   permissible,   to   provide   insurance
        themselves; or for other reasons;

                                    PAGE 14

        -      that   cancellations  may   increase   and
        persistency  may  decrease due  to  refinancings,
        changes   in   Freddie   Mac   or   Fannie    Mae
        cancellation  policies  or legislation  regarding
        mortgage insurance cancellation, or due to  other
        factors; and

        -     that delinquencies, incurred losses or paid
        losses  may  increase  as  a  result  of  adverse
        changes  in regional or national economies  which
        affect borrowers' incomes or housing values.

The  foregoing  "Safe Harbor" Statement  also  identifies
certain material risks of the Company's business.
