PART I

ITEM 1. BUSINESS

GENERAL

CMAC Investment Corporation (the "Company") provides, through its wholly
owned subsidiary, Commonwealth Mortgage Assurance Company ("CMAC"), private
mortgage insurance coverage in the United States to residential mortgage
lenders. Private mortgage insurance protects lenders from default-related losses
on residential first mortgage loans made to home buyers who make down payments
of less than 20% of the home's purchase price. Private mortgage insurance also
facilitates the sale of such mortgage loans in the secondary mortgage market,
principally to the Federal Home Loan Mortgage Corporation ("Freddie Mac") and
Fannie Mae. CMAC is restricted, generally by state insurance laws and
regulations and the eligibility requirements of Fannie Mae and Freddie Mac, to
providing insurance on residential first mortgage loans only. CMAC currently
offers two principal types of private mortgage insurance coverage: "primary" and
"pool". At December 31, 1997, primary insurance and pool insurance represented
94.4% and 5.6%, respectively, of CMAC's direct risk in force, and this
proportion is not expected to change materially in the future, although the
volume of pool insurance written increased significantly in 1997 and is expected
to continue at similar levels in 1998.

CMAC has been engaged in the mortgage insurance business since 1977. The
Company acquired all of the outstanding common stock of CMAC in October 1992 in
order to facilitate the initial public offering of the Company's common stock.
In the offering, the Company's sole stockholder, Commonwealth Land Title
Insurance Company ("Commonwealth"), then an indirect subsidiary of Reliance
Group Holdings, Inc. ("Reliance"), sold all of the shares of common stock of the
Company owned by it. As a result of the offering, which was completed in
November 1992, the Company became an independent public company.

Primary Insurance

Primary insurance provides mortgage default protection on individual loans
at a specified coverage percentage which is applied to the unpaid loan
principal, delinquent interest and certain expenses associated with the default
and subsequent foreclosure (collectively, the "claim amount"). CMAC's obligation
to an insured lender in respect of a claim is determined by applying the
appropriate coverage percentage to the claim amount. CMAC's "risk" on each
insured loan is the loan amount multiplied by the coverage percentage. Most of
CMAC's current business is written with 30% coverage on loans with a
loan-to-value ("LTV") ratio of 90.01% or higher and 25% coverage on loans with
an LTV ratio between 85.01% and 90%. As of December 31, 1997, approximately 60%
of CMAC's insurance in force has such "deeper coverage". Under its master
policy, CMAC has the option (which is infrequently used) of paying the entire
claim amount and taking title to the mortgaged property, or paying the coverage
percentage in full satisfaction of its obligations under the insurance written.

Pool Insurance

Pool insurance differs from primary insurance in that the exposure on pool
insurance is not limited to a specific coverage percentage on each individual
loan. There is an aggregate exposure limit ("stop loss") on a "pool" of loans
which is generally between 1% and 10% of the initial aggregate loan balance.
Modified pool insurance has a stop loss like pool insurance, but also has
exposure limits on each individual loan. The use of modified pool insurance is
much more limited than traditional pool insurance.

CMAC offers pool insurance on a selected basis to various state housing
finance agencies on the collateral for their bond issues, as a credit
enhancement to mortgage loans included in mortgage-backed securities or in whole
loan sales, and in certain other specific situations. Recently, CMAC has begun
to offer pool insurance on mortgage product sold to Freddie Mac and Fannie Mae
by CMAC's primary insurance customers ("GSE Pool"). This pool insurance has a
very low stop loss, generally 1.0% to 1.5%, and the insured pools contain

1
3

loans with and without primary insurance. Premium rates on this business are
significantly lower than primary insurance rates and therefore the expected
profitability on this business is lower than that of primary insurance. The
volume of such business increased significantly in 1997 due to the strong demand
for this product from CMAC's customers. During 1997, CMAC had pool risk written
of $264.5 million relating specifically to GSE Pool business. It is expected
that CMAC will write a similar amount of such pool insurance in 1998. It is
CMAC's current intention to limit net pool risk in force to approximately 5% of
CMAC's total risk in force. New premiums written for pool insurance were $4.8
million in 1997, $2.1 million in 1996 and $1.6 million in 1995.

Structured Transactions

CMAC, from time to time, engages in structured transactions which may
include either primary insurance, pool insurance or some form of combination. A
structured transaction generally involves insuring a large pool of seasoned
loans or issuing a commitment to insure new loan originations under negotiated
terms. Some structured transactions contain a risk-sharing component under which
the insured assumes a first-loss position or shares in losses in some other
manner. The amount of new premiums written in structured transactions by CMAC in
1997, 1996 and 1995 were $300,000, $400,000 and $1.3 million, respectively.

Revenue Sharing Products

CMAC and the industry have recently begun to offer financial products to
their customers that are designed to allow the customer to participate in the
risks and rewards of the mortgage insurance business. One such product is
captive reinsurance, in which a mortgage lender sets up a mortgage reinsurance
company that assumes part of the risk associated with that lenders' insured book
of business. In most cases, the risk assumed by the reinsurance company is an
excess layer of aggregate losses that would be penetrated only in a situation of
adverse loss development. CMAC had one captive reinsurance agreement in place at
December 31, 1997 and expects to enter into several new agreements in 1998.
Another revenue sharing product is a performance note ("SUPER Note"), which
allows a mortgage lender to invest a portion of capital needed to support its
insured mortgage insurance book and to receive a return on investment that
approximates the return that CMAC achieves on that same book of business. At
December 31, 1997, CMAC had $34,000 of outstanding SUPER Notes and plans to
issue many more in 1998. The aggregate amount of captive reinsurance and SUPER
Note business is not expected to have a material financial impact on CMAC's
balance sheet or financial results in 1998.

CUSTOMERS

Mortgage originators such as mortgage bankers, mortgage brokers, commercial
banks and savings institutions are CMAC's principal customers, although mortgage
borrowers generally bear the cost of primary insurance coverage. CMAC does, on a
limited basis, offer lender-paid mortgage insurance whereby mortgage insurance
premiums are charged to the mortgage lender or loan servicer. On the lender-paid
product, the interest rate to the borrower is usually higher to compensate for
the mortgage insurance premium that the lender is paying. In 1997, approximately
3% of CMAC's primary insurance was done on a lender-paid basis.

To obtain primary insurance from CMAC, a mortgage lender must first apply
for and receive a master policy from CMAC. CMAC's approval of a lender as a
master policyholder is based, among other factors, upon an evaluation of the
lender's financial position and its management's demonstrated adherence to sound
loan origination practices.

The number of primary individual policies in force at December 31, 1997,
1996 and 1995 was 441,605, 382,243 and 321,090, respectively.

CMAC's top 10 customers were responsible for 28.4% of new primary risk
written in 1997 compared to 21.8% and 24.7% for the years ended December 31,
1996 and 1995, respectively. The largest single customer of CMAC (including
branches and affiliates of such customer), measured by risk written, accounted
for 4.9% of new primary risk written during 1997 compared to 4.0% and 4.2% for
the years ended December 31, 1996 and 1995, respectively.

SALES, MARKETING AND COMPETITION

Sales and Marketing

CMAC employs a field sales force of approximately 100 persons, organized
into three divisions, providing local sales representation throughout the United
States. During 1997, CMAC reorganized by reducing the number of divisions from
six to three and introducing the new position of Area Sales Manager in order to
provide more direct supervision of the field sales force. Each of the three
divisions is supervised by a Divisional Sales Manager who is directly
responsible for several Area Sales Managers. The Area Sales Managers are
responsible for managing a small sales force in different areas within the
division. CMAC sales personnel are compensated by salary, commissions on new
insurance written and a production incentive based on the achievement of various
goals. During 1998, these goals will be related to volume, market share, change
in market share and business quality as measured by CMAC's mortgage scoring
model. In early 1997, CMAC expanded its effort to serve larger national
accounts, which have become a more integral part of the mortgage insurance
market due to consolidation in the mortgage lending industry. Two dedicated
national account positions were created and a more focused effort to support
national accounts was implemented. CMAC intends to keep adding to this effort in
1998 with at least one additional dedicated position.

Competition

CMAC and other private mortgage insurers compete directly with various
federal government agencies, principally the Federal Housing Administration
("FHA"). In addition to competition from federal agencies, CMAC and other
private mortgage insurers face competition from state-supported mortgage
insurance funds.

The private mortgage insurance industry consists of CMAC and seven other
active mortgage insurance companies. During 1997, CMAC was the fifth largest
private mortgage insurer and had, according to industry data, a market share of
new primary mortgage insurance written of 11.2%.

UNDERWRITING PRACTICES

CMAC considers effective risk management to be critical to its long-term
financial stability. Market analysis, prudent underwriting, the use of automated
risk evaluation models, quality control and customer service are all important
elements of CMAC's risk management process.

Underwriting Personnel

In addition to a centralized National Underwriting department in the home
office, each of CMAC's service divisions has a Divisional Service Manager
responsible for evaluating risk and managing all underwriting field staff in the
region. CMAC employs an underwriting and support staff of approximately 321, who
are located in CMAC's 25 service centers. Additionally, CMAC has two agency
operations in place.

Underwriting Process

CMAC has generally accepted applications for primary insurance (other than
in connection with structured transactions) under three basic programs: the
traditional fully documented program, a limited documentation program and the
delegated underwriting program. Programs that involve less than fully documented
file submissions have become more prevalent in recent years. In order to meet
this demand, in the fourth quarter of 1996, CMAC introduced to the marketplace a
new concept in mortgage insurance underwriting and processing. This process is
referred to as "ExpressTrac(sm)". A lender utilizing ExpressTrac can submit
loans to CMAC for insurance with abbreviated levels of documentation based on
the type of loan being submitted for insurance. During 1997, 16% of the
commitments issued for primary insurance were received by CMAC under the
ExpressTrac program. ExpressTrac is not a delegated underwriting program.
Rather, CMAC has agreed to underwrite certain loans with less documentation by
relying upon a scoring model created during 1996 referred to as "Prophet
Score(sm)" (described below). The ExpressTrac program also allows for a
reduction in standard premium rates (4 basis points) for loans having FICO
credit scores

3
5

(described below) of 680 or greater. During 1997, 48% of the commitments issued
by CMAC for primary insurance received this discounted rate.

Delegated Underwriting

CMAC has a delegated underwriting program with certain customers. CMAC's
delegated underwriting program, which was implemented in 1989, currently
involves only lenders that are approved by CMAC's risk management department.
Delegated underwriting programs allow the lender's underwriters to commit CMAC
to insure loans based on agreed upon underwriting guidelines. CMAC routinely
audits loans submitted under these programs. As of December 31, 1997,
approximately 33% of the primary loans on CMAC's books were originated on a
delegated basis and during 1997, 55% of the primary loans insured by CMAC were
originated on a delegated basis. This compares to 20% and 49%, in 1996.

Automated Underwriting

In 1994, CMAC installed an automated underwriting system which uses
artificial intelligence technology to assist its underwriting staff in the
processing of loan files. The system allows the underwriter to eliminate the
rudimentary underwriting steps and to focus on key aspects of the loan file,
with the ultimate goal of increasing underwriting efficiency while maintaining
the same level of risk exposure. During 1995, the system was fully integrated
into the CMAC underwriting process and improved efficiency was realized. In
1996, CMAC further enhanced the automated underwriting system by adding its
Prophet Score model to the automated underwriting systems' decision making
process. Direct connections between the CMAC network and Fannie Mae's Desktop
Underwriter and Freddie Mac's Loan Prospector systems were implemented in
January, 1998.

Mortgage Scoring Models

During the last few years, the use of scoring mechanisms to predict loan
performance has become prevalent in the marketplace, especially with Freddie
Mac's advocacy of the use of credit scores in the mortgage loan underwriting
process. The use of credit scores was pioneered by Fair Isaac and Company and
became popular in the mid-1980s. The FICO model calculates a score based on a
borrower's credit history. This credit score based "scorecard" is used to
predict the future performance of a loan over a one or two year time horizon.
The higher the credit score the lower the likelihood that a borrower will
default on a loan. CMAC's Prophet Score begins with a FICO score then adds
specific additional data regarding the borrower, the loan and the property. It
is this additional mortgage data that expands the integrity of CMAC's Prophet
Score over the entire life of the loan. In addition to the Prophet Score, our
housing analysts regularly review major metropolitan areas to assess the impact
that key indicators such as housing permits, employment trends, and median home
sale prices have on local lending. The healthier the real estate market, the
lower the risk. CMAC refers to this score as a GEOScore. Beginning in October,
1996, the Prophet Score and GEOScore appeared on each insurance commitment that
CMAC issued.

Alternative A Loans

An increasingly popular form of mortgage lending is in the area of
sub-prime loans. Two subsets of this category in which CMAC has recently become
involved are Alternative A loans and A minus loans. Alternative A borrowers have
an equal or better credit profile than CMAC's typical insured borrowers, but
these loans are underwritten with reduced documentation and verification of
information. CMAC typically charges a higher premium rate for this business due
to the reduced documentation, but does not consider this business to be
significantly more risky than its normal primary business. Alternative A loans
made up approximately 1% of primary insured business in 1997. The A minus loan
programs typically have non-traditional credit standards which are less
stringent than standard credit guidelines. This market was created as an avenue
to homeownership for borrowers who had not properly maintained their credit
profile over time. CMAC receives a significantly higher premium for insuring
this product that is commensurate with the additional default risk and is often
a variable rate based on Prophet Score. During 1997, less than 1% of CMAC's
primary insurance written was done on A minus loans. CMAC intends to limit its
participation in the sub-prime market to Alternative A and A minus loans rather
than "B" or "C" (lower credit) loans and to
4
6

limit the business insured to specific targeted lenders with proven good results
and servicing experience in this area.

Contract Underwriting

CMAC utilizes its underwriting skills to provide an outsource contract
underwriting service to its customers. For a fee, CMAC underwrites fully
documented underwriting files for secondary market compliance, while at the same
time assessing the file for mortgage insurance, if applicable. During the fourth
quarter of 1997, CMAC introduced its automated underwriting service on a pilot
basis. This service offers customers access to Fannie Mae's Desktop Underwriter
and Freddie Mac's Loan Prospector. Contract underwriting has increased in
popularity among CMAC's customers over the last few years. During 1997, loans
underwritten via contract underwriting accounted for 29% of applications, 25% of
commitments for insurance and 22% of insurance certificates issued by CMAC. CMAC
often gives recourse to its customers on loans it underwrites for compliance. If
the loan does not meet agreed upon guidelines and is not salable in the
secondary market for that reason, CMAC agrees to remedy the situation either by
placing mortgage insurance coverage on the loan or by purchasing the loan.
During 1997, less than 1% of all loans were subject to these remedies and the
costs associated with these remedies were negligible. There is no assurance that
these low levels will continue in the future.

RATINGS

CMAC, along with other active private mortgage insurers, has its
claims-paying ability and financial strength rated by Standard & Poor's ("S&P"),
Moody's Investors Service, Inc. ("Moody's") and Duff & Phelps Credit Rating
Company ("DCR"). These ratings are an indication to a mortgage insurer's
customers of the insurer's present financial strength and its capacity to honor
its future claims payment obligations. Ratings are generally considered critical
to an insurer's ability to compete for new insurance business. Currently, CMAC
is rated "AA" by S&P and DCR, and "Aa3" by Moody's.

REINSURANCE

CMAC reinsures all direct insurance in force under an excess of loss
reinsurance program which CMAC considers to be an effective catastrophic
reinsurance coverage. This program originally utilized three reinsurers, but
beginning on January 1, 1995, the program was reduced to one reinsurer. The
reinsurer is responsible for 100% of CMAC's covered losses in excess of CMAC's
retention. CMAC's annual retention is determined by a formula which contains
variable components. The estimated 1998 retention is approximately $410 million
of loss. The reinsurer's aggregate annual limit of liability is also determined
by a formula with variable components and is currently estimated to be $80
million. If the reinsurer decides not to renew the reinsurance arrangement and
is not replaced by CMAC, the nonrenewing reinsurer must provide six years of
runoff coverage. There is an overall aggregate limit of liability applicable to
any runoff period equal to four times the annual limit in effect for the
calendar year of such nonrenewal. For 1998, this aggregate limit is estimated to
be $320 million.

The excess of loss reinsurance program also provides restrictions and
limitations on (i) payment of dividends by CMAC; (ii) investments; (iii) mergers
or acquisitions involving other private mortgage insurance companies; and (iv)
reinsurance of exposure retained by CMAC.

In addition, CMAC has entered into a variable quota-share ("VQS") treaty
for primary risk in the 1994 to 1997 origination years and a portion of the pool
risk written in 1997. In this treaty, quota-share loss relief is provided at
varying levels ranging from 7.5% to 15.0% based upon the loss ratio on the
reinsured book. The higher CMAC's loss ratio, the greater the potential
reinsurance relief which protects CMAC in adverse loss situations. A ceding
commission is paid by the reinsurer to CMAC and the agreement is noncancelable
for ten years by either party. As of December 31, 1997, the risk in force
covered by the VQS treaty was approximately $8.7 billion, or approximately 81%
of CMAC's primary risk in force and $100 million, or approximately 17% of CMAC's
pool risk in force. It is CMAC's present intention to reinsure a specific
portion of its pool insurance

5
7

risk in 1998 under a new reinsurance treaty and not cede any additional business
pursuant to the VQS treaty for the 1998 origination year.

DEFAULTS AND CLAIMS

Defaults

The default and claim cycle on loans which have private mortgage insurance
begins with the insurer's receipt from the lender of notification of a default
on an insured loan. The master policy requires lenders to notify CMAC of an
uncured default on a mortgage loan within 75 days (45 days for an uncured
default in the first year of the loan), although many lenders do so earlier. The
recent trend has been earlier notification of defaults by servicers. The
incidence of default is affected by a variety of factors, including change in
borrower income, unemployment, divorce and illness, the level of interest rates
and general borrower creditworthiness. Defaults that are not cured result in
claims to CMAC. Borrowers may cure defaults by making all delinquent loan
payments or by selling the property and satisfying all amounts due under the
mortgage.

The following table shows the number of primary and pool loans insured,
related loans in default and the percentage of loans in default (default rate)

As of December 31, 1997, default rates for CMAC's two largest states
measured by risk in force, California and Florida, were 3.6% and 3.8%,
respectively, compared to 4.0% and 3.2% at December 31, 1996. The increase in
the Florida default rate is due primarily to the increased "affordable housing"
business done in Florida since 1994 and the relatively high default development
on such business.

Claims

The likelihood that a claim will result from a default and the amount of
such claim depend principally on the borrower's equity 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, as well as the
effectiveness of loss mitigation efforts. Claims are also affected by local
housing prices, interest rates, unemployment levels and the housing supply.

Claim activity is not evenly spread through the coverage period of a book
of business. Relatively few claims are received during the first two years
following issuance of the policy. 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.
Approximately 62% of CMAC's primary risk in force and most of CMAC's pool risk
in force at December 31, 1997 had not yet reached its anticipated highest claim
frequency years. CMAC's cumulative claim incidence on insurance written,
determined four years after policy issuance, was 2.0% for insurance written in
1991, 1.5% for insurance written in 1992, and 1.5% for insurance written in
1993. Certain "affordable housing" loans insured in 1994 and 1995 have
experienced higher than normal early default and claim rates, although it is too
early to determine how much higher the eventual claim rates on such loans will
be compared to prior books of business. Many of the reasons for these early
defaults have been addressed in the underwriting of such loans in 1996 and 1997.

LOSS MITIGATION

Once a default notice is received, CMAC attempts to mitigate its loss. The
CMAC loan workout department consists of 30 employees, including 17 full-time
workout specialists. Through proactive intervention with insured lenders and
borrowers, CMAC attempts to reduce the number and severity of CMAC's claim
payments. Loss mitigation techniques include pre-foreclosure sales, extensions
of credit to certain borrowers to reinstate insured loans, loan modifications
and deficiency settlements with borrowers. CMAC considers its loss mitigation
efforts to be an effective way to reduce net claim payments.

HOMEOWNERSHIP COUNSELING

In 1995, CMAC established a Homeownership Counseling Center (the "Center")
to work with borrowers receiving insured loans under Community Homebuyer, 97%
loan-to-value ("97s") or other "affordable housing" programs. CMAC considers
this counseling to be very important to the future success of those particular
borrowers with regard to sustaining their mortgage payments. In addition, the
Center counsels such borrowers early in the default process in an attempt to
help cure the loan and assist the borrower in meeting their mortgage obligation.
During 1996, after reviewing results of analyses showing loans counseled by the
Center were performing better than those counseled by others, CMAC took the
proactive step of requiring that counseling on loans it insures be done by the
Center or by a counseling entity that CMAC has reviewed and approved.

LOSS RESERVES

CMAC establishes reserves to provide for the estimated costs of settling
claims in respect of loans reported to be in default and loans that are in
default which have not yet been reported to CMAC. Consistent with generally
accepted accounting principles and industry accounting practices, CMAC does not
establish loss reserves for future claims on insured loans which are not
currently in default. In determining the liability for unpaid losses related to
reported outstanding defaults, CMAC establishes loss reserves on a case-by-case
basis. The amount reserved for any particular loan is dependent upon the status
of the loan as reported by the servicer of the insured loan, as well as the
economic condition and estimated foreclosure period in the area in which the
default exists. As the default progresses closer to foreclosure, the amount of
loss reserve for that particular loan will be increased, in stages, to
approximately 100% of CMAC's exposure.

ANALYSIS OF PRIMARY RISK IN FORCE

CMAC's business strategy has been to disperse risk as widely as possible.
CMAC analyzes its portfolio in a number of ways to identify any concentrations
or imbalances in risk dispersion. CMAC believes the quality of its insurance
portfolio is affected significantly by (i) the geographic dispersion of the
properties securing the insured loans; (ii) the quality of loan originations;
(iii) the types of loans insured (including LTV ratio, purpose of the loan, type
of loan instrument and type of underlying property securing the loan); and (iv)
the age of the loans insured.

Geographic Dispersion

The following tables reflect the percentage of direct primary risk in force
on CMAC's book of business (by location of property) for the top ten states and
top 15 metropolitan statistical areas ("MSAs") as of December 31, 1997 and 1996:

Lender and Product Characteristics

While geographic dispersion is an important component of overall risk
dispersion and it has been a strategy of the Company to reduce its exposure in
the top ten states and top fifteen MSAs, the Company

8
10

believes the quality of the risk in force should be considered in conjunction
with other elements of risk dispersion, such as product distribution, as well as
CMAC's risk management and underwriting practices.

The following table reflects the percentage of direct risk in force (as
determined on the basis of information available on the date of mortgage
origination) by the categories indicated as of December 31, 1997 and 1996.

(1) Includes traditional and modified pool insurance.
(2) Refers to loans where payment adjustments are the same as mortgage interest
rate adjustments.
(3) Loans with potential negative amortization will not have increasing
principal balances unless interest rates increase as contrasted with
scheduled negative amortization where an increase in loan balance will occur
even if interest rates do not change.

One of the most important determinants of claim incidence is the relative
amount of borrower's equity in the home, or down payment. The expectation of
claim incidence on loans having an LTV ratio in excess of 90% ("95s") is
approximately two times the expected claim incidence on loans with LTV ratios
equal to or less than 90% and over 85% ("90s"). CMAC believes that the higher
premium rates it charges on 95s adequately reflect the additional risk on these
loans. The industry and CMAC began to insure 97s in 1995. These loans are
expected to have a higher claim incidence than 95s; however, with proper
counseling efforts and by limiting insurance on these loans to sensible
affordable housing programs, it is CMAC's belief that the claim incidence should
not be materially (more than one and one-half times) worse than on 95s, although
this cannot be certain. Early defaults on 97s as compared to other loans have
confirmed CMAC's expectations, although the eventual performance of these loans
cannot yet be accurately projected. Premium rates on 97s are higher than on 95s
to compensate for the additional risk and the higher expected frequency and
severity of claims. The amount of 97s insured in 1997 and 1996 was between 3%
and 4% of the total loans insured each year and the percentage of primary risk
in force on insured 97s went from 2.2% at the end of 1996 to 2.6% at the end of
1997. The percentage of 97s written in 1998 should approximate the 1997 and 1996
figures.

In recent years, CMAC has increased its insurance on mortgages identified
by its customers as "affordable housing" loans. These loans are typically made
to low- and moderate-income borrowers in conjunction with special programs
developed by state or local housing agencies, Fannie Mae or Freddie Mac. Such
programs usually include 95s and 97s and may require certain underwriting
guidelines to be liberalized in order to achieve their objectives. CMAC's
participation in these programs is dependent upon acceptable borrower
counseling. Early default experience on these programs has been worse than non
"affordable housing" loans, however CMAC does not believe the ultimate claims
will materially affect its financial results due to the relatively small amount
of such business combined with higher premium rates and risk-sharing elements.

CMAC's claim frequency on insured ARMs has been higher than on all other
loan types. The Company believes that the risk on ARM loans is greater than on
fixed rate loans due to possible monthly payment increases if interest rates
rise.

The Company believes that 15-year mortgages present a lower level of risk
than 30-year mortgages, primarily as a result of the faster amortization and the
more rapid accumulation of borrower equity in the property. Premium rates for
15-year mortgages are lower to reflect the lower risk.

The Company believes that the risk of claim is also affected by the type of
property securing the insured loan. In the Company's opinion, loans on
single-family detached housing are subject to less risk of claim incidence than
loans on other types of properties. Conversely, loans on attached housing types,
particularly condominiums and cooperatives, are generally considered by the
Company to be a higher risk, due to the

10
12

higher density of such properties and because a detached unit is the preferred
housing type in most areas. CMAC's more stringent underwriting guidelines on
condominiums and cooperatives reflect this higher expected risk.

The Company believes that the risk of claim on relocation loans and loans
originated by credit unions is extremely low and has begun to offer lower
premium rates on such loans to compensate for the lower risk.

The Company believes that loans on non-owner occupied homes purchased for
investment purposes represent a substantially higher risk of claim incidence,
and are subject to greater value declines than loans on either primary or second
homes. CMAC underwrites loans on non-owner occupied homes more stringently, and
sometimes requires that the investor indemnify CMAC directly for any loss
suffered by CMAC. CMAC also charges a higher premium rate than the rate charged
for insuring loans on owner occupied homes.

The Company believes that higher priced properties experience wider
fluctuations in value than moderately priced residences and that the income of
many people who buy higher priced homes is less stable than that of people with
moderate incomes. Underwriting guidelines for such higher priced properties
reflect this concern.

INVESTMENT PORTFOLIO

The Company's income from its investment portfolio is one of the Company's
primary sources of cash flow to support its operations and claim payments.

The Company follows an investment policy which, at a minimum, requires: (i)
95% of its investment portfolio to consist of cash equivalents and debt
securities (including redeemable preferred stocks) which, at the date of
purchase, were rated investment grade by a nationally recognized rating agency
(e.g., "BBB" or better by S&P), and (ii) at least 50% of its investment
portfolio (together with cash assets) to consist of cash, cash equivalents and
debt securities (including redeemable preferred stocks) which, at the date of
purchase, were rated the highest investment grade by a nationally recognized
rating agency (e.g., "AAA" by S&P). In December 1997, the Company's investment
policy was amended to permit investment in equity securities (including
convertible debt and convertible preferred stock). This equity component is not
permitted to exceed 20% of the total investment portfolio and the Company
intends to begin investing in equity securities in 1998. In addition, all
investments purchased in 1998 will be classified as available for sale in
contrast to the existing portfolio which contains mostly held to maturity
investments.

At December 31, 1997, the Company's investment portfolio had a carrying
value of $596.9 million and a market value of $626.9 million, including $11.0
million of short-term investments. At December 31, 1997, the Company's
investment portfolio did not include any real estate or mortgage loans. It did
include two private placement investment-grade preferred securities with a
carrying value of $2.8 million. At December 31, 1997, 100% of the Company's
investment portfolio (which excludes cash) consisted of cash equivalents and
debt securities (including redeemable preferred stocks) rated investment grade.

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

REGULATION

Direct Regulation

State Regulation

The Company and its insurance subsidiaries are subject to comprehensive,
detailed regulation principally designed for the protection of policyholders,
rather than for the benefit of investors, by the insurance departments in the
various states where the Company and its insurance subsidiaries are licensed to
transact business. Insurance laws vary from state to state, but generally grant
broad supervisory powers to agencies or officials to examine insurance companies
and enforce rules or exercise discretion affecting almost every significant
aspect of the insurance business.

Insurance regulations relate, among other things, to the licensing of
companies to transact business, claims handling, reinsurance requirements,
premium rates and policy forms offered to customers, financial statements,
periodic reporting, permissible investments and adherence to financial standards
relating to surplus, dividends and other criteria of solvency intended to assure
the satisfaction of obligations to policyholders.

Mortgage insurers are generally restricted to writing residential mortgage
guaranty insurance business only. This restriction essentially prohibits CMAC
from using its capital resources in support of other types of insurance or
non-insurance business. The non-insurance businesses of the Company, which
consist of mortgage insurance related services, are not generally subject to
regulation under state insurance laws.

Insurance Holding Company Regulation. All states have enacted legislation
that requires each insurance company in an insurance holding company system to
register with the insurance regulatory authority of its state of domicile and to
furnish to such regulator financial and other information concerning the
operations of companies within the holding company system that may materially
affect the operations, management or financial condition of insurers within the
system.

Because the Company is an insurance holding company and CMAC is a
Pennsylvania insurance company, the Pennsylvania insurance laws regulate, among
other things, certain transactions in the Company's Common Stock and certain
transactions between CMAC, the other insurance subsidiaries and their parent or
affiliates. Specifically, no person may, directly or indirectly, offer to
acquire or acquire "control" of the Company, CMAC or the other insurance
subsidiaries unless such person files a statement and other

13
15

documents with the Pennsylvania Commissioner of Insurance and obtains the
Commissioner's prior approval. The Commissioner may hold a public hearing on the
matter. "Control" is presumed to exist if 10% or more of CMAC or another of the
Company's insurance subsidiaries' voting securities is owned or controlled,
directly or indirectly, by a person, although the Pennsylvania Commissioner of
Insurance may find that "control" in fact does or does not exist where a person
owns or controls a lesser amount of securities. In addition, material
transactions between CMAC and the Company's other insurance subsidiaries and
their parent or affiliates are subject to certain conditions, including that
they be "fair and reasonable." These restrictions generally apply to all persons
controlling or under common control with CMAC or the Company's other insurance
subsidiaries. Certain transactions between the Company's insurance subsidiaries
and their parent or affiliates may not be entered into unless the Pennsylvania
Commissioner of Insurance is given 30 days prior notification and does not
disapprove the transaction during such 30-day period.

Dividends. The insurance laws of Pennsylvania establish a test limiting
the maximum amount of dividends which may be paid without prior approval by the
Pennsylvania Insurance Commissioner. Under such test, CMAC may pay dividends
during any 12-month period in an amount equal to the greater of: (i) 10% of the
preceding year-end statutory policyholders' surplus or (ii) the preceding year's
statutory net income. In accordance with such restrictions, $93.4 million would
be available for dividends in 1998. However, an amendment to the Pennsylvania
statute, effective in 1994, requires that dividends and other distributions be
paid out of an insurer's unassigned surplus. Because of the unique nature of the
method of accounting for contingency reserves, CMAC has negative unassigned
surplus. Thus, prior approval by the Pennsylvania Insurance commissioner is
required for CMAC to pay dividends or make other distributions so long as CMAC
has negative unassigned surplus. The Pennsylvania Insurance Commissioner has
approved all distributions by CMAC since the passage of this amendment, and
management has every expectation that the Insurance Department will continue to
approve such distributions in the future, provided that the financial condition
of CMAC does not materially change. The State of California has a statute
requiring mortgage insurers to pay dividends or make other distributions out of
unassigned surplus. CMAC and the California Department of Insurance have reached
an understanding under which CMAC will be able to pay dividends or make other
distributions to the Company provided that the financial condition of CMAC does
not materially change.

Risk to Capital. A number of states and Freddie Mac limit a private
mortgage insurer's risk in force to 25 times the insurer's total policyholders'
surplus (which includes the statutory contingency reserve), commonly known as
the "risk-to-capital" requirement. As of December 31, 1997, CMAC's
risk-to-capital ratio was 18.3 to 1, versus 18.4 to 1 in 1996.

Reserves. For statutory reporting, each year CMAC is required to provide
for additions to the contingency 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. The contingency reserve, designed to be a reserve against
catastrophic losses, essentially restricts dividends and other distributions by
CMAC. Prior to 1995, CMAC had included the contingency reserve as a component of
policyholders' surplus. The Pennsylvania Insurance Department has determined
that the contingency reserve should be classified as a liability in the
statutory balance sheet rather than as a component of policyholders' surplus. In
response to this determination, commencing in January 1995, CMAC began
classifying the contingency reserve as a liability. At December 31, 1997, CMAC
had policyholders' surplus of $148.1 million and a contingency reserve of $364.4
million.

Premium Rates and Policy Forms. CMAC's premium rates and policy forms are
subject to regulation in every state in which it is licensed to transact
business in order to protect policyholders against the adverse effects of
excessive, inadequate or unfairly discriminatory rates and to encourage
competition in the insurance marketplace. In most states, premium rates and
policy forms must be filed prior to their use. In some states, such rates and
forms must also be approved prior to use. Changes in premium rates are subject
to justification, generally on the basis of the insurer's loss experience,
expenses and future trend analysis. The general default experience in the
mortgage insurance industry may also be considered.

Reinsurance. Certain restrictions apply under the laws of several states
to any licensed company ceding business to an unlicensed reinsurer. Under such
laws, if a reinsurer is not admitted or approved in such states,

14
16

the company ceding business to the reinsurer cannot take credit in its statutory
financial statements for the risk ceded to such reinsurer absent compliance with
certain reinsurance security requirements. In addition, several states also have
special restrictions on mortgage guaranty insurance. Also, several states limit
the amount of risk a mortgage insurer may retain with respect to coverage on an
insured loan to 25% of the insured's claim amount. Coverage in excess of 25%
(i.e., deep coverage) must be reinsured.

Examination. The Company's insurance subsidiaries are subject to
examination of their affairs by the insurance departments of each of the states
in which they are licensed to transact business.

Federal Regulation

RESPA. The origination or refinance of a federally regulated mortgage loan
is a settlement service, and therefore subject to the Real Estate Settlement
Practices Act of 1974, and the regulations promulgated thereunder (collectively,
"RESPA"). In December 1992, regulations were issued which made clear that
mortgage insurance is also a settlement service, and therefore, that mortgage
insurers are subject to the provisions of Section 8(a) of RESPA, which generally
prohibits persons from accepting anything of value for referring real estate
settlement services to any provider of such services. Although many states
prohibit mortgage insurers from giving rebates, RESPA has been interpreted to
cover many non-fee services as well. HUD's interest in pursuing violations of
RESPA has increased awareness of both mortgage insurers and their customers of
the possible sanctions of this law.

HMDA. Most originators of mortgage loans are required to collect and
report data relating to a mortgage loan applicant's race, nationality, gender,
marital status and census tract to HUD or the Federal Reserve under the Home
Mortgage Disclosure Act of 1975 ("HMDA"). The purpose of HMDA is to detect
possible discrimination in home lending and, through disclosure, to discourage
such discrimination. Mortgage insurers are not required pursuant to any law or
regulation to report HMDA data, although under the laws of several states,
mortgage insurers are currently prohibited from discriminating on the basis of
certain classifications.

The active mortgage insurers, through their trade association, Mortgage
Insurance Companies of America ("MICA"), entered into an agreement with the
Federal Financial Institutions Examinations Council ("FFIEC") to report the same
data on loans submitted for insurance as is required for most mortgage lenders
under HMDA. The first report of HMDA-type data was collected by MICA from its
members for the fourth quarter of 1993 and reported to the FFIEC in the first
quarter of 1994. Subsequent reports of HMDA-type data for the mortgage insurance
industry were submitted by MICA to the FFIEC in March 1995, 1996 and 1997.
Management is not aware of any pending or expected actions by governmental
agencies in response to the reports submitted by MICA to the FFIEC.

MI Cancellation. From time to time, proposals have been advanced in both
houses of Congress which would permit or require cancellation of mortgage
insurance under certain conditions. In 1997, such proposals resulted in one bill
that passed in the House of Representatives and another bill approved by the
Senate. Such proposals would impose certain new requirements, the most
significant of which would require termination of mortgage insurance when a
loan's LTV ratio reaches a specified level, set at 78% in the Senate bill and
80% in the House of Representatives bill. Bills intending to accomplish the same
result have also been introduced in several state legislatures. Such bills
propose the automatic cancellation of mortgage insurance certificates upon the
occurrence of a triggering event such as the reduction of the LTV ratio to a
specified level, the aging of the loan for a specified number of years, or some
combination. Additionally, Fannie Mae has indicated its intention to issue
guidelines to its seller/servicers which would require the automatic
cancellation of mortgage insurance with similar triggering parameters. The
Company cannot predict if or when any of the foregoing legislation or guidelines
will be adopted or effective, but if adopted, and depending upon the nature and
extent of the cancellation parameters required, the persistency of CMAC's
insured loans could be adversely affected. The Company feels that any possible
outcome will have an immaterial impact on CMAC's insured book of business and on
the Company's financial results.

15

Other Direct Regulation

Freddie Mac and Fannie Mae

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. Freddie Mac's current
eligibility requirements impose limitations on the type of risk insured,
standards for the geographic and customer diversification of risk, procedures
for claims handling, acceptable underwriting practices and financial
requirements which generally mirror state insurance regulatory requirements.
These requirements are subject to change from time to time. Fannie Mae also has
eligibility requirements, although such requirements are not published. CMAC is
an approved mortgage insurer for both Freddie Mac and Fannie Mae.

In 1995, Freddie Mac and Fannie Mae began to require deeper coverage on
certain loans with LTV ratios greater than 85%. The Company believes that this
deeper coverage will not have a material effect on its financial results,
although premiums earned and the provision for losses will increase and the
risk-to-capital ratio will be higher as a result of the increase in risk.

In 1995, CMAC issued a new Master Policy which applies to all business
written after June 1, 1995. Changes in the terms include a broader scope of
coverage for certain environmental and bankruptcy related claims, and somewhat
more limited rights to reject claim payments, neither of which the Company
believes will have a material adverse effect on CMAC's operations or financial
results. The new Master Policy has been approved by Fannie Mae and Freddie Mac,
as well as by all states which require approval of policy forms.

Indirect Regulation

The Company and CMAC are also indirectly, but significantly, impacted by
regulations affecting originators and purchasers of mortgage loans, particularly
Freddie Mac and Fannie Mae, and regulations affecting governmental insurers such
as the FHA and VA. Private mortgage insurers, including CMAC, are highly
dependent upon federal housing legislation and other laws and regulations which
affect the demand for private mortgage insurance and the housing market
generally. For example, legislation which increases the number of persons
eligible for FHA or VA mortgages could have a material adverse effect on the
Company's ability to compete with the FHA or VA.

From time to time, budgets proposed by the President have included
proposals that would raise the FHA single-family loan limit. A similar proposal
is expected to be included in President Clinton's proposed 1998-99 budget. The
Company cannot predict when or if such a proposal will be adopted, but if
adopted, demand for private mortgage insurance may be adversely affected.

Proposals have been advanced which would allow Fannie Mae and Freddie Mac
additional flexibility in determining the amount and nature of alternative
recourse arrangements or other credit enhancements which they could utilize as
substitutes for private mortgage insurance. The Company cannot predict if or
when any of the foregoing legislation or proposals will be adopted, but if
adopted and depending upon the nature and extent of revisions made, demand for
private mortgage insurance may be adversely affected. There can be no assurance
that other federal laws affecting such institutions and entities will not
change, or that new legislation or regulations will not be adopted. In addition,
Fannie Mae and Freddie Mac have entered into, and may in the future seek to
enter into, alternative recourse arrangements or other credit enhancements based
on their existing legislative authority.

Political pressures to simplify the nation's tax code could, among other
things, result in the partial or entire loss of the U.S. federal income tax
deduction for mortgage loan interest, which could result in downward pressure on
housing prices. Any reduction or loss of such deduction could reduce the volume
of low down payment mortgages originated and private mortgage insurance written
and adversely impact mortgage default patterns, and could materially affect the
Company's business.

Recent discussions with the Federal Trade Commission with regard to the
adverse action disclosure provisions of the Fair Credit Reporting Act ("FCRA")
have raised the possibility that CMAC will need to

16
18

make certain changes to its loan servicing and tracking procedures in order to
give FCRA adverse action notices directly to borrowers. The Company does not
believe that such changes will have a material effect on its operations.

There can be no assurance that the above-mentioned federal laws and
regulations or other federal laws and regulations affecting lenders, private and
governmental mortgage insurers, or purchasers of insured mortgage loans, will
not be amended, or that new legislation or regulations will not be adopted, in
either case, in a manner which will adversely affect the demand for private
mortgage insurance.

YEAR 2000 ISSUE

Many existing computer programs use only two digits to identify a year in
the date field. These programs were designed and developed without considering
the impact of the upcoming change in the century. If not corrected, many
computer applications could fail or create erroneous results by or at the year
2000. The Company has conducted an analysis of its systems and has concluded
that all such systems will be Year 2000 compliant by the end of 1998. "Year 2000
compliant" means fault free performance in the processing of data and date
related data (including, but not limited to, calculating, comparing and
sequencing) by all hardware and software products, individually and in
combination. Fault free performance must include the manipulation of data when
dates are in the 20th or 21st century and must be transparent to the user.
Nevertheless, in the event that third parties with whom the Company transacts
business are not Year 2000 compliant, potential for an adverse effect on the
Company's operations may remain. The Company is taking precautions to minimize
this risk. The Company expects that its Year 2000 compliance program will not
result in any material costs nor have any material impact on its financial
condition.

EMPLOYEES

At December 1997, CMAC had 607 employees, of which approximately one-third
were located at its Philadelphia headquarters facility. CMAC's employees are not
unionized and management considers employee relations to be very good.

ITEM 2. PROPERTIES

The Company leases approximately 59,000 square feet for its corporate
headquarters in Philadelphia under leases which expire in 2003. In addition,
CMAC leases space for its Divisional, Service Center and On-Site offices
throughout the United States comprising approximately 57,000 square feet with
leases expiring between 1997 and 2001. With respect to all facilities, the
Company believes it will be able to obtain satisfactory lease renewal terms.

The Company believes its existing properties are well utilized and are
suitable and adequate for its present circumstances.

The Company maintains a mini-computer network from its corporate data
center located in its headquarters building to support its data processing
requirements for accounting, claims, marketing, risk management, underwriting
and non-insurance operations. In 1997, the Company centralized all computer
operations. All the service centers are linked to the home office in
Philadelphia via a high speed frame-relay network. The centralized environment
is based on the Business Recovery Server (BRS) architecture. The BRS consists of
two geographically dispersed, identical data centers. Each data center is
currently running at 30% of capacity. Either data center is capable of
supporting the entire company. The data centers are linked via a fibre-optic
link allowing simultaneous data updates through disk shadowing. Each center is
part of a separate power grid. This redundant configuration provides disaster
tolerance and automatic back-up, resource sharing and fail-over.

ITEM 3. LEGAL PROCEEDINGS

CMAC is involved in certain litigation arising in the normal course of its
business. CMAC is contesting the allegations in each pending action and
believes, based on current knowledge and after consultation with

17
19

counsel, that the outcome of such litigation will not have a material adverse
effect on the Company's consolidated financial position and results of
operations.

CMAC INVESTMENT CORPORATION

SCHEDULE III -- CONDENSED FINANCIAL INFORMATION OF REGISTRANT
PARENT COMPANY ONLY
SUPPLEMENTARY NOTES

NOTE A

The accompanying Parent Company financial statements should be read in
conjunction with the Consolidated Financial Statements and Notes to Consolidated
Financial Statements appearing on pages 15 through 31 of the CMAC Investment
Corporation 1997 Annual Report to Stockholders.

NOTE B

CMAC Investment Corporation (the "Company") was incorporated in December,
1991 in order to hold the capital stock of Commonwealth Mortgage Assurance
Company ("CMAC"). In the fourth quarter of 1992, a merger among controlled
subsidiaries of CMAC was consummated with the effect that the Company acquired
all of the outstanding stock of CMAC, and CMAC's sole stockholder, Commonwealth
Land Title Insurance Company ("Commonwealth"), then an indirect wholly owned
subsidiary of Reliance Group Holdings, Inc., acquired all of the outstanding
capital stock of the Company.

In the fourth quarter of 1992, the initial public offering of the Company's
common stock (the "Offering") was consummated. In the Offering, Commonwealth
sold all of the 7,000,000 shares owned by it, and the Company issued and sold
3,950,000 shares. In addition, the Company issued and sold 800,000 shares of
$4.125 Preferred Stock to Commonwealth. Aggregate proceeds to the Company from
the sale of common stock were approximately $67,200,000 and from the sale of
preferred stock were $40,000,000.

The preferred stock, issued in connection with the Offering, is entitled to
cumulative annual dividends of $4.125 per share, payable quarterly in arrears.
The preferred stock is redeemable at the option of the Company at $54.125 per
share on or after August 15, 2002, and declining to $50.00 per share on or after
August 15, 2005 (plus in each case accumulated and unpaid dividends), or is
subject to mandatory redemption at a redemption price of $50.00 per share plus
accumulated and unpaid dividends based upon specified annual sinking fund
requirements from 2002 to 2011.

The Company is a holding company whose principal source of income is
dividends from CMAC. The ability of CMAC to pay dividends on its common stock is
restricted by certain provisions of the insurance laws of the Commonwealth of
Pennsylvania, its state of domicile. The insurance laws of Pennsylvania
establish a test limiting the maximum amount of dividends which may be paid by
an insurer without prior approval by the Pennsylvania Insurance Commissioner.
Under such test, CMAC may pay dividends during any 12-month period in an amount
equal to the greater of (i) 10% of the preceding year-end statutory
policyholders' surplus or (ii) the preceding year's statutory net income. In
accordance with such restrictions, $93,390,000 would be available for dividends
in 1998. However, an amendment to the Pennsylvania statute, effective in 1994,
requires that dividends and other distributions be paid out of an insurer's
unassigned surplus. Because of the unique nature of the method of accounting for
contingency reserves, CMAC has negative unassigned surplus. Thus, prior approval
by the Pennsylvania Insurance Commissioner is required for CMAC to pay dividends
or make other distributions so long as CMAC has negative unassigned surplus. The
Pennsylvania Insurance Commissioner has approved all distributions by CMAC since
the passage of this amendment and management has every expectation that the
Commissioner of Insurance will continue to approve such distributions in the
future, provided that the financial condition of CMAC does not materially
change.

The State of California has a statute requiring mortgage insurers to pay
dividends or make other distributions out of unassigned surplus. CMAC and the
California Department of Insurance have reached an understanding under which
CMAC will be able to pay dividends or make other distributions to the Company
provided that the financial condition of CMAC does not materially change.

In addition, CMAC's current excess of loss reinsurance arrangement
prohibits the payment of any dividend which would have the effect of reducing
its total policyholders' surplus (which includes contingency

reserve) below $85,000,000. As of December 31, 1997, CMAC's total policyholders'
surplus was $512,469,000.

The Company and CMAC have entered into an agreement pursuant to which the
Company has agreed to establish and, for so long as any shares of $4.125
Preferred Stock remain outstanding, maintain a reserve account in an amount
equal to three years of dividend payments on the outstanding shares of $4.125
Preferred Stock (currently $9.9 million), and not to pay dividends on the common
stock at any time when the amount in the reserve account is less than three
years of dividend payments on the shares of $4.125 Preferred Stock then
outstanding. This agreement between the Company and CMAC provides that the
holders of the $4.125 Preferred Stock are entitled to enforce the agreement's
provisions as if such holders were signatories to the agreement.

The Company may not pay any dividends on shares of common stock unless the
Company has paid all accrued dividends on and has complied with all sinking fund
and redemption obligations relating to its outstanding shares of $4.125
Preferred Stock.

NOTE C

On October 15, 1996, the Board of Directors authorized a stock split, paid
on December 2, 1996, in the form of a dividend of one additional share of the
Company's common stock for each share owned by stockholders of record on
November 7, 1996. The dividend was accounted for as a two-for-one stock split
and par value remained at $.001 per share.

Accordingly, all references to common share and per-share data have been
adjusted to give effect to the stock split.
