                                 (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  nine
months  ended September 30, 1998 may not be indicative of  the
results that may be expected for the year ending December  31,
1998.

Note 2 - Notes payable
 
    In June of 1998, the Company completed a $250 million bank
loan agreement with several lending institutions to finance  a
Stock Repurchase program in addition to the repurchase program
completed  in 1997. The weighted average interest rate on  the
notes  payable for borrowings under the 1997 and  1998  credit
agreements  was 5.89% per annum at September 30,1998.

     The  1997 and 1998 credit facilities provide up  to  $225
million  and  $250 million, respectively, of  availability  at
September  30, 1998.  The 1997 credit facility  will  decrease
by  $25  million  each  year   through  June  20,  2001.   Any
outstanding borrowings under this facility mature on June  20,
2002.  The 1998 credit facility decreases by $25 million  each
year  beginning  June  9,  1999 through  June  9,  2002.   Any
outstanding borrowings under this facility mature on  June  9,
2003.  The  Company has the option, on notice to  lenders,  to
prepay  any borrowings under the agreements subject to certain
provisions.

    Under the terms of the credit facilities, the Company must
maintain shareholders' equity of at least $1 billion and  MGIC
must  maintain a claims paying ability rating of AA- or better
with Standard & Poor's Corporation ("S&P").  At September  30,
1998, the Company had shareholders' equity of $1.6 billion and
MGIC had a claims paying ability rating of AA+ from S&P.

                                    PAGE 6

     Mortgage Guaranty Insurance Corporation ("MGIC") is
guaranteeing one half of a $50  million  credit facility for
C-BASS, a 48% owned unconsolidated joint venture. The facility
matures in July 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.

Note 4 - 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.

     Earnings per share for 1997 has been restated to  reflect
the  provisions of SFAS 128. The Company's previously reported
EPS for 1997 equaled diluted EPS under SFAS 128.

Note 5 - Comprehensive income

     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    Nine Months Ended
                                September 30,        September 30,

                                    PAGE 7

    The difference  between the Company's net income and total
comprehensive  income  for the three  and  nine  months  ended
September  30,  1998  and  1997  is  due  to   the  change  in
unrealized  appreciation on  investments, net of tax.

Note 6 - New accounting standards

     In  June  1998, the Financial Accounting Standards  Board
issued  Statement of Financial Accounting Standards  No.  133,
Accounting  for Derivative Instruments and Hedging  Activities
("SFAS  133"), which will be effective for all fiscal quarters
of  all  fiscal  years  beginning after  June  15,  1999.  The
statement  establishes accounting and reporting standards  for
derivative    instruments   and   for   hedging    activities.
Management does not anticipate the adoption of SFAS  133  will
have  a  significant  effect  on  the  Company's  results   of
operations or its financial position due to its limited use of
derivative instruments.

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


Results of Consolidated Operations

  Three  Months Ended September 30, 1998 Compared  With  Three
  Months Ended September 30, 1997

     Net  income for the three months ended September 30, 1998
was  $96.5  million, compared to $84.2 million  for  the  same
period  of  1997,  an increase of 15%.  Diluted  earnings  per
share  for the three months ended September 30, 1998 was $0.86
compared to $0.72 in the same period last year, an increase of
19%.  See note 4 to the consolidated financial statements.

     The  amount of new primary insurance written by  Mortgage
Guaranty  Insurance  Corporation  ("MGIC")  during  the  three
months ended September 30, 1998 was $11.8 billion, compared to
$9.1  billion in the same period of 1997. Refinancing activity
accounted  for  24% of new primary insurance  written  in  the
third quarter of 1998, compared to 12% in the third quarter of
1997.

      New  insurance  written  for  adjustable-rate  mortgages
("ARMs") decreased to 9% of new insurance written in the third
quarter of 1998 from 26% of new insurance written in the  same
period of 1997. Mortgages with loan-to-value ("LTV") ratios in
excess  of 90% but not more than 95% ("95%") decreased to  40%
of new insurance written in the third quarter of 1998 from 42%
of  new  insurance written in the same period of 1997.   Also,
mortgages with 95% LTVs and 30% coverage decreased to  37%  of
new insurance written in the third quarter of 1998 compared to
39% in the same period of 1997.

     The $11.8 billion of new primary insurance written during
the  third  quarter of 1998 was offset by the cancellation  of
$11.5  billion of insurance in force, and resulted  in  a  net
increase  of  $0.3  billion  in primary  insurance  in  force,
compared to new primary insurance written of $9.1 billion, the
cancellation  of  $6.6  billion, and a net  increase  of  $2.5
billion  in  insurance in force during the  third  quarter  of
1997.  Direct primary insurance in force was $137.8 billion at
September 30, 1998 compared to $138.5 billion at  December 31,
1997 and $136.7 billion at September 30, 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 September 30, 1998 was  $154 million, which
was virtually all agency pool insurance.  The Company's direct
pool risk in  force  at September 30, 1998  was $966.8 million
compared to  $590.3  million  at  December 31, 1997 and $455.6
million at September 30, 1997 and is expected to increase as a
result of outstanding commitments  to  write additional agency
pool insurance.

                                    PAGE 9
 
     Cancellation  activity increased during the  last  twelve
months 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  71.5%
at  September  30,  1998  from 82.2% at  September  30,  1997.
Cancellation activity could increase due to factors other than
refinances  and home sales due to recently enacted legislation
regarding cancellation of mortgage insurance.

     Net premiums written were $190.6 million during the third
quarter  of 1998, compared to $184.0 million during the  third
quarter of 1997.  Net premiums earned were $191.1 million  for
the  third quarter of 1998 compared to $180.5 million for  the
same period in 1997. The increases were primarily a result  of
a  higher  percentage of  renewal premiums on  mortgage  loans
with  deeper  coverages and the growth in insurance  in  force
since September 30, 1997.

     MGIC continues to enter various risk sharing arrangements
with its customers. These arrangements have not had a material
impact on underwriting income thus far in 1998.  New insurance
written  subject to risk sharing arrangements is  expected  to
increase   and  may  have  a material impact  on  underwriting
results in the future.

     Investment income for the third quarter of 1998 was $36.5
million,  an  increase of 16% over the $31.6  million  in  the
third quarter of 1997.  This increase was primarily the result
of  an  increase  in  the amortized cost of  average  invested
assets to $2.5 billion for the third quarter of 1998 from $2.1
billion for the third quarter of 1997, an increase of 16%. The
portfolio's average pre-tax investment yield was 5.7% for  the
third  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 third quarter of 1998 and 5.0% for the same period  in
1997.   The Company realized gains of $2.6 million during  the
three months ended September 30, 1998 resulting primarily from
the  sale  of fixed maturities compared to realized  gains  of
$1.5 million during the same period in 1997.

     Other revenue was $10.7 million for the third quarter  of
1998  compared to $10.2 million for the same period  in  1997.
The  increase is primarily the result of an increase  in  fee-
based services for underwriting.

     Net losses incurred decreased 15% to $51.5 million during
the  third quarter of 1998 from $60.8 million during the third
quarter of 1997.  Such decrease was primarily attributed to an
increase  in  the  redundancy in prior year loss reserves  and
generally   favorable  economic  conditions   throughout   the
country.  The redundancy results from actual claim  rates  and
actual  claim amounts being lower than those estimated by  the
Company    when   originally   establishing  the  reserve   at
December  31,  1997.   At September 30, 1998,  55%  of  MGIC's
insurance  in  force was written during the  preceding  eleven
quarters,  compared to 53% at September 30, 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.

                                    PAGE 10

     Underwriting  and  other  expenses  increased   to  $46.5
million in the third quarter of 1998 from $39.9 million in the
third  quarter of 1997, an increase of 17%. This increase  was
primarily  due  to  an  increase in expenses  associated  with
underwriting  and  an increase in premium tax  due  to  higher
premiums written.

     Interest  expense increased to $5.3 million in the  third
quarter  of 1998 from $2.5 million during the same  period  in
1997.   The increase is the result of additional debt incurred
to  fund  the  stock repurchase program. See  note  2  to  the
consolidated financial statements.

    The consolidated insurance operations loss ratio was 26.9%
for  the third quarter of 1998 compared to 33.7% for the third
quarter of 1997. The consolidated insurance operations expense
and  combined  ratios were 18.8% and 45.7%, respectively,  for
the  third quarter of 1998 compared to 17.2% and 50.9% for the
third quarter of 1997.

     The effective tax rate was 30.3% in the third quarter  of
1998,  compared to 30.8% in the third 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  lower effective  tax  rate  in  1998
resulted  from a higher percentage of total income before  tax
being generated from tax-preferenced investments.

  Nine  Months  Ended  September 30, 1998 Compared  With  Nine
  Months Ended September 30, 1997

     Net  income for the nine months ended September 30,  1998
was  $285.8 million, compared to $237.2 million for  the  same
period  of  1997,  an increase of 20%.  Diluted  earnings  per
share  for the nine months ended September 30, 1998 was  $2.49
compared to $2.00 in the same period last year, an increase of
25%.  See note 4 to the consolidated financial statements.

    The amount of new primary insurance written by MGIC during
the  nine  months ended September 30, 1998 was $31.1  billion,
compared  to  $23.3  billion  in  the  same  period  of  1997.
Refinancing   activity  accounted  for  30%  of  new   primary
insurance  written in the first nine months of 1998,  compared
to 14% for the same period in 1997.

      New  insurance written for ARMs decreased to 11% of  new
insurance written in the first nine months of 1998 from 27% of
new  insurance written in the same period of 1997.   Mortgages
with 95% LTVs decreased to 37% of new insurance written in the
first nine months of 1998 from 42% of new insurance written in
the  same  period of 1997.  Also, mortgages with 95% LTVs  and
30%  coverage decreased to 34% of new insurance written during
the  first  nine months of 1998 compared to 39%  in  the  same
period of 1997.

                                    PAGE 11

     The $31.1 billion of new primary insurance written during
the  first  nine months of 1998 was offset by the cancellation
of  $31.8 billion of insurance in force, and resulted in a net
decrease  of  $0.7  billion  in primary  insurance  in  force,
compared  to  new primary insurance written of $23.3  billion,
the  cancellation of $18.0 billion, and a net increase of $5.3
billion in insurance in force during the first nine months  of
1997.   Direct  primary insurance in force was $137.8  billion
at  September 30, 1998 compared to $138.5 billion at  December
31,  1997  and  $136.7  billion at  September  30,  1997.   In
addition to providing  primary insurance coverage, the Company
also  insures pools of mortgage loans.  New pool risk  written
during  the  nine  months ended September 30,  1998  was  $446
million,  which was virtually all agency pool insurance.   The
Company's direct pool risk in force at September 30, 1998  was
$966.8 million compared to $590.3 million at December 31, 1997
and  $455.6  million at September 30, 1997 and is expected  to
increase as  a  result  of outstanding  commitments  to  write
additional agency pool insurance.

     Cancellation  activity increased during the  last  twelve
months 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  71.5%
at  September  30,  1998  from 82.2% at  September  30,  1997.
Cancellation activity could increase due to factors other than
refinances  and home sales due to recently enacted legislation
regarding cancellation of mortgage insurance.

     Net premiums written were $553.7 million during the first
nine  months  of 1998, compared to $510.5 million  during  the
first  nine  months of 1997. Net premiums earned  were  $570.1
million  for the first nine months of 1998 compared to  $524.3
million  for  the  same  period in 1997.  The  increases  were
primarily a result of a higher percentage of  renewal premiums
on  mortgage  loans with deeper coverages  and the  growth  in
insurance in force since September 30, 1997.

     MGIC continues to enter various risk sharing arrangements
with its customers. These arrangements have not had a material
impact on underwriting income thus far in 1998.  New insurance
written  subject to risk sharing arrangements is  expected  to
increase  and  may  have  a material  impact  on  underwriting
results in the future.

     Investment income for the first nine months of  1998  was
$106.2 million, an increase of 16% over the $91.4 million  for
the  same  period  in 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 nine months  of
1998  from $2.0 billion for the first nine months of 1997,  an
increase  of  15%. The portfolio's average pre-tax  investment
yield was 5.7% for the first nine months of 1998 and 5.8%  for
the  same  period  in 1997. The portfolio's average  after-tax
investment  yield was 4.9% for the first nine months  of  1998
and  5.0%  for the same period in 1997.  The Company  realized
gains  of $13.9 million during the nine months ended September
30,   1998  resulting  primarily  from  the  sale  of   equity
securities compared to realized gains on investments  of  $2.1
million during the same period in 1997.

                                    PAGE 12

     Other revenue was $32.7 million for the first nine months
of 1998 compared to $21.9 million for the same period in 1997.
The  increase is primarily the result of an increase  in  fee-
based  services  for  underwriting  of  $8.4  million  and  an
increase  of  $4.3  million of equity  earnings  from  C-BASS,
offset by a decrease of $2.2 million in fee-based services for
premium reconciliation and claim administration.

    Net losses incurred decreased 10% to $163.4 million during
the  first nine months of 1998 from $182.2 million during  the
first  nine  months  of  1997.  Such  decrease  was  primarily
attributed  to  an increase in the  redundancy in  prior  year
loss  reserves  and  generally favorable  economic  conditions
throughout  the country.  The redundancy results  from  actual
claim  rates and actual claim amounts being lower  than  those
estimated  by  the  Company  when originally establishing  the
reserve at December 31, 1997.  At September 30, 1998,  55%  of
MGIC's  insurance  in force was written during  the  preceding
eleven  quarters, compared to 53% at September 30,  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  $137.2
million  in the first nine months of 1998 from $116.0  million
for the same period in 1997, an increase of 18%. This increase
was  primarily due to an increase in expenses associated  with
underwriting  and  an increase in premium tax  due  to  higher
premiums written.

     Interest expense increased to $12.4 million in the  first
nine  months of 1998 from $2.8 million during the same  period
in  1997.   The  increase  is the result  of  additional  debt
incurred to fund the stock repurchase program.  See note 2  to
the consolidated financial statements.

    The consolidated insurance operations loss ratio was 28.7%
for  the  first nine months of 1998 compared to 34.8% for  the
first   nine  months  of  1997.  The  consolidated   insurance
operations  expense and combined ratios were 19.2% and  47.9%,
respectively,  for the first nine months of 1998  compared  to
18.6% and 53.4% for the first nine months of 1997.

     The effective tax rate was 30.6% in the first nine months
of  1998,  compared  to  30.5% for the same  period  in  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.

                                    PAGE 13

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  $295.1  million  for  the  nine  months  ended
September 30, 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  $2.7  billion  at
September  30, 1998, compared to $2.4 billion at December  31,
1997,  an increase of 12%.  This increase is due primarily  to
positive  cash flow from operations.  The investment portfolio
includes  unrealized gains on securities marked to  market  at
September 30, 1998 and December 31, 1997 of $174.3 million and
$129.2  million, respectively.  As of September 30, 1998,  the
Company  had  $121.4  million of short-term  investments  with
maturities of 90 days or less.   In addition, at September 30,
1998,   based   on   amortized  cost,  the   Company's   total
investments,   which   were  primarily  comprised   of   fixed
maturities, were approximately 99% invested in "A"  rated  and
above,   readily   marketable  securities,   concentrated   in
maturities of less than 15 years.

     The  Company's investment in C-BASS was $52.7 million  at
September 30, 1998,  which  includes  the  Company's  share of
C-BASS's earnings since inception of C-BASS.  As discussed  in
Note 2 to  the  Consolidated Financial Statements, the Company
is  guaranteeing  one  half  of a $50  million  C-BASS  credit
facility.  The Company expects that it will provide additional
funding  for  C-BASS.  C-BASS  evaluates, purchases,  services
and securitizes  assets in the  market  of sub-performing  and
non-performing  residential   mortgages.  In  accordance  with
generally accepted  accounting principles,  C-BASS  is required
to mark its assets to market.  Such mortgage related assets are
exposed to market valuation  adjustments which could impact the
Company's share of C-BASS's results of operations.

     Consolidated loss reserves increased 8% to $644.1 million
at September 30, 1998 from $598.7 million at December 31, 1997
reflecting  an increase in the estimated number  of  loans  in
default.  Consistent with industry practices, the Company does
not establish loss reserves for future claims on insured loans
which are not currently in default.

     Consolidated  unearned premiums decreased  $18.8  million
from $198.3 million at December 31, 1997 to $179.5 million  at
September  30,  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  $2.3 million to $6.9 million at September
30,  1998  from  $9.2 million at December 31, 1997,  primarily
reflecting the reduction in unearned premiums.

                                    PAGE 14
            
    Consolidated   shareholders'  equity  increased  to   $1.6
billion at  September 30, 1998,  from $1.5 billion at December
31,  1997,  an  increase  of 6%.  This increase  consisted  of
$285.8  million of net income during the first nine months  of
1998,  an  increase in net unrealized gains on investments  of
$29.3  million,  net  of  tax,  and  $14.5  million  from  the
reissuance  of  treasury stock offset by approximately  $231.2
million for the repurchase of approximately 4.7 million shares
of  the  Company's  outstanding  common  stock  and  dividends
declared of $8.5 million.

    MGIC is the principal insurance subsidiary of the Company.
MGIC's risk-to-capital ratio was 13.9:1 at September 30,  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 $393.2 million, net of
reinsurance, during the first nine months of 1998.

      The   Company's   combined   insurance   risk-to-capital
ratio was 14.5:1 at September 30, 1998, compared to 16.4:1  at
December  31, 1997.  The decrease was due to the same  reasons
as described above.

       During 1998, the Company repurchased approximately  4.7
million  shares  of its common stock under its  current  stock
repurchase program at a cost of approximately $231.2  million.
Funds  for  the repurchase program are provided under  a  bank
loan  facility  and from operating cash flow.   The  Company's
previous  $250 million stock repurchase program was  completed
in   1997.     See  note  2  to  the  consolidated   financial
statements.

Year 2000  Compliance

      Almost  all  of  the  Company's  information  technology
systems   ("IT  Systems"),  including  all  of  its  "business
critical" IT Systems, either have been originally developed to
be Year 2000 compliant or have been reprogrammed.  The Company
plans  to  reprogram  the  remaining Systems  (the  "Remaining
Systems")  and to complete internal testing of all IT  Systems
for  Year 2000 compliance by the end of the second quarter  of
1999.   In general, the Remaining IT Systems have either  been
developed   and   maintained  by  the  Company's   Information
Technology  Department  or  use  off-the-shelf  software  from
national  software vendors such as Microsoft and IBM who  have
publicly announced that their software is Year 2000 compliant.
All  of  the  IT  Systems  developed  and  maintained  by  the
Information  Technology Department have already been  assessed
for  Year  2000 compliance and a portion of the Systems  using
off-the-shelf software have been assessed.  If the Company  is
unable to complete any required reprogramming of the Remaining
Systems  on a timely basis, the efficiency of certain  of  the
Company's  business  processes will likely  decline  but  this
consequence is not expected to be material to the Company.

                                    PAGE 15

     Some  of  the  Company's "business critical"  IT  Systems
interface  with  computer  systems  of  third  parties.    The
Company,  Fannie  Mae, Freddie Mac and  many  of  these  third
parties  are participating in the Mortgage Bankers Association
Year  2000  Inter-Industry Work Group (the "MBA Work  Group").
The  Company understands that the MBA Work Group is  surveying
its  participants  about  their  interest  in  conducting  and
scheduling  compliance testing during  the  first  and  second
quarters  of  1999  as  well as how  such  testing  should  be
structured.  The Company and one national service bureau  have
already  conducted  certain successful  Year  2000  compliance
testing and it is possible the Company will conduct additional
Year  2000  compliance  testing with individual  companies  in
advance  of the MBA Work Group testing.  However, the  Company
understands it is the position of a number of larger companies
in  the MBA Work Group not to engage in any testing with third
parties  in advance of the testing sponsored by the  MBA  Work
Group.    The Company intends to contact its largest customers
not  participating in the MBA Work Group testing to  determine
interest in one-on-one testing.

     All  costs incurred through September 1998 for IT Systems
for   Year  2000  compliance  have  been  expensed  and   were
immaterial.   The  costs  of the remaining  reprogramming  and
testing are expected to be immaterial.

    If the Company is unable to do business with third parties
electronically,  the Company would seek to  do  business  with
them  on a paper basis. As discussed below, the Company is  in
the process of developing a Year 2000 contingency plan and has
not yet made an assessment of the effects on its operations of
having  to  replace  a  substantial portion  of  the  business
conducted  electronically with business conducted on  a  paper
basis.

     Telecommunications services and electricity are essential
to  the  Company's ability to conduct business.  The Company's
long-distance voice and data telecommunications suppliers  and
the  local  telephone  company  serving  the  Company's  owned
headquarters  and  warehouse facilities have  written  to  the
Company  to the effect that their respective systems  will  be
Year  2000  compliant.  The  electric  company  serving  these
facilities has given the Company oral assurance that  it  will
also  be  Year 2000 compliant.   In addition, the  Company  is
exploring the feasibility of acquiring back-up power  for  its
headquarters. The Company is seeking assurance regarding  Year
2000  compliance from landlords of the Company's  underwriting
service  centers  and  has received  letters  from  the  local
telephone  companies providing service to those  centers  that
they will be Year 2000 compliant.

     The  Company has begun developing a Year 2000 contingency
plan.  The  process to complete a plan is expected  to  extend
into 1999.
     
     For  the portion of the Company's "Safe Harbor" Statement
relating  to   Year 2000 matters, see "Safe Harbor"  Statement
below.

                                    PAGE 16

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:

       --demand  for  mortgages may be adversely  affected  by
       increases   in   interest   rates,   adverse   economic
       conditions, decreases in housing affordability or as  a
       result of other factors;

       --the  Company's  new insurance written,  new  premiums
       written  or,  with respect to certain  of  the  factors
       below, its market share may be adversely affected as  a
       result  of:  factors affecting or relating to  mortgage
       demand,  government housing policy (including the  FHA)
       and  the programs of Freddie Mac and Fannie Mae or  the
       provisions  of  their charters with respect  to  credit
       enhancements  on low down payment mortgages  that  they
       purchase;  the competitive environment in the  mortgage
       insurance  industry,  including underwriting  criteria,
       pricing  or  products offered; decisions by lenders  or
       investors  (including Fannie Mae and  Freddie  Mac)  to
       originate  or  purchase low down  payment  loans  using
       reduced   levels   of  mortgage  insurance   or   using
       substitutes  for mortgage insurance, including  to  the
       extent legally permissible, self-insurance or insurance
       provided   by  affiliates;  consolidation   among   the
       Company's  customers  resulting  in  changes  in  their
       mortgage insurance relationships; or other reasons;
     
       --insurance in force, persistency and renewal  premiums
       may  be adversely affected due to:  refinancings (which
       are affected by changes in interest rates); changes  in
       Fannie   Mae  or  Freddie  Mac  cancellation  policies;
       legislation   regarding   cancellation   of    mortgage
       insurance; or other reasons; and

       --credit quality may be adversely affected 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.

                                    PAGE 17

In  addition,  with  respect  to  forward  looking  statements
regarding  Year 2000 compliance, there is the  risk  that  the
timetables for completing Year 2000 compliance actions may  be
delayed  due to Company personnel devoting time and  attention
to non-Year 2000 projects.

ITEM 3.  QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET
         RISK

     At  September  30,  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 September 30, 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 facilities  are
subject  to  interest  rates that are  variable.   Changes  in
market interest rates would have minimal impact on the   value
of  the  notes  payable.   See  note  2  to  the  consolidated
financial statements.
