Exhibit 99.1

                          Actuate Files 10-Q


    SOUTH SAN FRANCISCO, Calif.--(BUSINESS WIRE)--June 9,
2003--Actuate Corporation (Nasdaq:ACTUE), the world leader in scalable
Business Intelligence Applications, today announced that the company
has filed its Quarterly Report on Form 10-Q for the first quarter of
2003. The accounting review of selected sales contracts by the
company's Audit Committee and independent auditors resulted in a
reduction in revenues of $384,000 for the first quarter ended March
31, 2003 to $25,130,000 compared with $25,514,000 reported on April
29, 2003. The review also resulted in an increase in benefit for
income taxes of $170,000. On a GAAP basis, Actuate's net loss was
$836,000 or $0.01 per share for the first quarter of 2003 compared
with a net loss of $622,000 or $0.01 per share reported on April 29,
2003.
    Actuate did not restate financial statements from prior periods
because the amounts were determined to be immaterial to the periods in
which they should have been recorded.
    During the preparation of its 10-Q, Actuate's management
discovered that one of the company's sales representatives had entered
into an unauthorized side agreement with an international distributor.
On May 5, 2003, Actuate's Audit Committee initiated an internal review
of selected transactions executed at international locations and
entered into in fiscal years 2001, 2002 and the first quarter ended
March 31, 2003. As a result of the review, additional unauthorized
side agreements, customer allegations of unauthorized side
arrangements and other matters relating to revenue recognition were
identified resulting in the adjustments to revenues and net income
outlined above.
    "Actuate takes very seriously any violations of company policy, no
matter how small, associated with contractual terms and conditions,"
said Pete Cittadini, Actuate's president and chief executive officer.
"We worked closely with the Audit Committee and independent auditors
to conduct a very thorough review to be sure we uncovered all
unauthorized agreements. The process took longer than expected but we
are confident that we did discover all unauthorized arrangements. We
are pleased that the issue was isolated to a few transactions
resulting in relatively small adjustments to the figures we previously
announced for Q1 2003. Furthermore, we are committed to apply what we
learned during the review process to improve our current corporate
governance and internal control best practices."
    With the filing of its 10-Q, Actuate expects its trading symbol on
the Nasdaq National Market to return to ACTU within a few days.
    The 10-Q filing is available electronically on the Actuate website
