CUSIP NO. 303250104              SCHEDULE 13D                     Page 7 of 10


This Amendment No. 5 amends the Statement on Schedule 13D (the "Schedule 13D")
filed with the Securities and Exchange Commission (the "Commission") on June
3, 2003 by Blum Capital Partners, L.P., a California limited partnership
("Blum L.P."); Richard C. Blum & Associates, Inc., a California corporation
("RCBA Inc."); Blum Strategic GP, L.L.C., a Delaware limited liability company
("Blum GP"); Blum Strategic GP II, L.L.C., a Delaware limited liability
company ("Blum GP II"); and Richard C. Blum, the Chairman and a substantial
shareholder of RCBA Inc. and a managing member of Blum GP and Blum GP II
(collectively, the "Reporting Persons").  This Amendment relates to shares of
Common Stock, par value $0.01 (the "Common Stock") of Fair Isaac Corporation,
a Delaware corporation (the "Issuer").  The principal executive office and
mailing address of the Issuer is 200 Smith Ranch Road, San Rafael, California
94903.  The following amendments are hereby made.  Unless otherwise defined
herein, all capitalized terms shall have the meanings ascribed to them in the
Schedule 13D.


Item 5.  Interest in Securities of the Issuer
- ---------------------------------------------

Item 5 of the Schedule 13D is hereby amended as follows:

(a),(b) According to the Issuer's most recent Form 10-Q, there were 47,161,737
shares of Common Stock issued and outstanding as of March 31, 2003.  Based on
such information, after taking into account the transactions described in Item
5(c) below, the Reporting Persons report beneficial ownership of the following
shares of Common Stock:(i) 1,998,976 shares of the Common Stock held by Blum
L.P. and RCBA Inc. on behalf of the limited partnerships for which Blum L.P.
serves as the general partner, or on behalf of an entity for which Blum L.P.
serves as investment advisor, which represents 4.2% of the outstanding shares
of Common Stock; (ii) 536,625 shares of the Common Stock held by Blum GP on
behalf of the limited partnership for which it serves as the general partner,
which represents 1.1% of the outstanding shares of Common Stock; (iii)
1,305,268 shares of the Common Stock held by Blum GP II on behalf of the
limited partnership for which it serves as the general partner and on behalf
of the limited partnership for which it serves as the managing limited
partner, which represents 2.8% of the outstanding shares of Common Stock; and
(iv) 624,346 shares of the Common Stock that are legally owned by Carpenters
Pension Trust for Southern California ("Carpenters") and 134,605 shares of the
Common Stock that are legally owned by United Brotherhood of Carpenters
Pension Plan ("UBC")(collectively, the "Investment Advisory Clients"), with
respect to which Blum L.P. has voting and investment power. The Investment
Advisory Clients represent 1.6% of the outstanding shares of Common Stock.
Each Investment Advisory Client has entered into an advisory agreement with
Blum L.P., but neither Investment Advisory Client has any contract,
arrangement or understanding with the other Investment Advisory Client, or any
other Reporting Person, with respect to the acquisition, ownership,
disposition or voting of any shares of the Common Stock.  Each Investment
Advisory Client disclaims membership in a group with any Reporting Person or
with the other Investment Advisory Client, and each disclaims beneficial


CUSIP NO. 303250104              SCHEDULE 13D                    Page 8 of 10

ownership of any shares beneficially owned by the Reporting Persons other than
for their own account.

Voting and investment power concerning the above shares are held solely by
Blum L.P., Blum GP and Blum GP II.  The Reporting Persons therefore may be
deemed to be members in a group, in which case the group would be deemed to
have beneficial ownership of an aggregate of 4,599,820 shares of the Common
Stock, which is 9.8% of the outstanding Common Stock.  As the sole general
partner of Blum L.P., RCBA Inc. is deemed the beneficial owner of the
securities over which Blum L.P. has voting and investment power.  As Chairman,
director and a substantial shareholder of RCBA Inc., Richard C. Blum might be
deemed to be the beneficial owner of the securities beneficially owned by RCBA
Inc.  Additionally, Mr. Blum may be deemed to be the beneficial owner of the
securities over which Blum GP and Blum GP II have voting and investment power.
Although Mr. Blum is joining in this Schedule as a Reporting Person, the
filing of this Schedule shall not be construed as an admission that he, or any
of the other shareholders, directors or executive officers of RCBA Inc., or
any of the managing members and members of Blum GP and Blum GP II, is, for any
purpose, the beneficial owner of any of the securities that are beneficially
owned by RCBA Inc., Blum GP or Blum GP II.

(c)  Since the most recent filing of Schedule 13D, the Reporting Persons sold
the following shares of Common Stock in the open market:


Entity                            Trade Date    Shares   Price/Share
- ------                            ----------    ------   ------------
Investment partnerships for       06-03-03      74,400     55.0128
which Blum L.P. serves as the
general partner and on behalf
of an entity for which
Blum L.P. serves as investment
advisor
