the previously announced restructuring plan of $3.4 million after-tax,
or $0.05 per diluted share.

prior years' tax liabilities.

    The company reported year-to-date revenues of $618.1 million
versus $595.4 million in the prior year period. Net income for

    Third Quarter Fiscal 2006 Revenues Highlights

    Revenues for third quarter fiscal 2006 across each of the
company's four operating segments were as follows:

    --  Strategy Machine(R) Solutions revenues were $114.8 million in
        the third quarter compared to $115.1 million in the prior year
        quarter, or a decrease of 0.2%, primarily due to a decline
        associated with marketing services and insurance solutions,
        offset by an increase in revenues derived from fraud
        solutions.

    --  Scoring Solutions revenues increased to $43.7 million in the
        third quarter from $40.7 million in the prior year quarter, or
        by 7.4%, primarily due to an increase in revenues derived from
        risk scoring services at the credit reporting agencies and
        PreScore(R) Service.

    --  Professional Services revenues increased to $36.7 million in
        the third quarter from $33.2 million in the prior year
        quarter, or by 10.6%, primarily due to an increase in revenues
        from strategic consulting services.

    --  Analytic Software Tools revenues were $11.9 million in the
        third quarter compared to $14.8 million in the prior year
        quarter, or a decrease of 19.8%, due to a decline in revenues
        generated from sales of the Blaze Advisor(TM) product.

    Fiscal 2006 Year-to-date Revenues Highlights

    Year-to-date revenues for fiscal 2006 across each of the company's
four operating segments were as follows:

    --  Strategy Machine Solutions revenues increased to $345.7
        million from $344.2 million in the prior year period, or by
        0.4%, primarily due to growth in consumer scoring products and
        fraud products, offset by a decline associated with marketing
        services and insurance solutions.

    --  Scoring Solutions revenues increased to $131.7 million from
        $119.5 million in the prior year period, or by 10.2%,
        primarily due to an increase in revenues derived from risk
        scoring services at the credit reporting agencies, and
        PreScore Service.

    --  Professional Services revenues increased to $108.2 million
        from $96.3 million in the prior year period, or by 12.4%,
        primarily due to increases in revenues from strategic
        consulting services and implementation services for EDM
        products, offset by a decline in consulting services related
        to precision marketing.

    --  Analytic Software Tools revenues were $32.5 million compared
        to $35.5 million in the prior year period, or a decrease of
        8.3%, due to a decline in revenues generated from sales of the
        Blaze Advisor product.

    Bookings Highlights

    The bookings for the third quarter were $94.5 million versus
$143.3 million in the same period last year. The company defines a
"new booking" as estimated future contractual revenues, including
agreements with perpetual, multi-year and annual terms. Management
regards the volume of new bookings achieved, among other factors, as
an important indicator of future revenues, but they are not comparable
to, nor should they be substituted for, an analysis of the company's
revenues.

    Balance Sheet and Cash Flow Highlights

    Cash and cash equivalents, and marketable security investments
were $353.2 million at June 30, 2006, as compared to $288.1 million at
September 30, 2005. Significant changes in cash and cash equivalents
from September 30, 2005 include cash provided by operations of $153.9
million for fiscal 2006 and $56.2 million received from the exercise
of stock options and stock issued under an employee stock purchase
plan. Cash used during fiscal 2006 includes $24.3 million related to
purchases of property and equipment and $124.1 million to repurchase
company stock under the currently authorized share repurchase plan.
The remaining balance of the existing share repurchase authorization
is $47.3 million.

    Restructuring Activities

    On June 15, 2006, the company announced the details of a
restructuring plan designed to accelerate growth. As part of the
restructuring, the company incurred severance and related costs of
$3.4 million after-tax, or $0.05 per diluted share, in the third
quarter of fiscal 2006.
    Separate from the restructuring, the company has identified excess
real estate that will be vacated in the fourth quarter of fiscal 2006.
Vacating the excess real estate will result in a fourth quarter charge
of approximately $8.4 million, after-tax, or $0.13 per diluted share,
representing future cash obligations under the lease, net of sublease
income. The company expects that the future lease obligations will be
paid out over the next five years, which represents the remaining
lease period. The company also expects to yield an annualized
reduction of rent expense of approximately $2.3 million to $2.8
million, after-tax, through the remaining lease period.

    Outlook

    Fourth Quarter 2006

    The company expects revenues for fourth quarter fiscal 2006 of
approximately $207.0 million, of which Product (Scoring, Strategy
Machines and Analytic Software Tools) revenues will account for
approximately $170.0 million and Professional Services revenues will
account for approximately $37.0 million. The company also expects
earnings per diluted share for the quarter to be approximately $0.33,
which includes an expected after-tax compensation expense of
approximately $7.1 million, or $0.11 per diluted share, related to
SFAS 123(R) and approximately $8.4 million, or $0.13 per diluted share
related to vacating excess real estate as noted above.
    "We remain confident that our client-centric approach will
accelerate our growth in new vertical and international markets," said
Thomas Grudnowski, Fair Isaac's chief executive officer. "We also
expect continued steady growth in core areas, including FICO(R)
scores, our Falcon(TM) Fraud franchise and our TRIAD(TM) solutions.
The ongoing demand for our EDM solutions is a testament to our
customers' and prospects' growing appreciation of the unique value we
can deliver."

(a) The computation of diluted earnings per share for the nine months
    ended June 30, 2005 includes 6.0 million shares of common stock
    issuable upon conversion of our senior convertible notes, along
    with a corresponding adjustment to net income to add back related
    interest expense, net of tax, of approximately $2.5 million. On
    March 31, 2005, the company successfully completed an exchange
    offer for approximately 99.9% of the principal amount of its
    senior convertible notes for new senior convertible notes. The
    dilutive effect of the new senior convertible notes has been
    calculated using the treasury stock method since the effective
    date of the exchange.

(b) Effective October 1, 2005, the company adopted SFAS 123(R),
    "Share-Based Payment", which required the company to record
    compensation expense for all share-based awards. Results from
    prior periods have not been restated.
