    Use of Non-GAAP Financial Measures

    The non-GAAP financial measures discussed in the text of this
press release and accompanying non-GAAP supplemental information
represent financial measures used by Actuate's management to evaluate
the operating performance of the Company and to conduct its business
operations. Non-GAAP financial measures discussed in this press
release exclude the amortization of intangibles and other costs
arising from acquisitions, amortization of deferred compensation,
restructuring charges, certain legal and accounting fees and an
adjustment to the tax provision. It is management's belief that these
items are not indicative of ongoing operations and as a result,
non-GAAP financial measures that exclude such items provide additional
insight for investors in evaluating the Company's financial and
operational performance. However, these non-GAAP financial measures
are not intended to be an alternative to financial measures prepared
in accordance with GAAP. Pursuant to the requirements of SEC
Regulation G, a detailed reconciliation between the Company's GAAP and
non-GAAP financial results is provided in this press release and
investors are advised to carefully review and consider this
information as well as the GAAP financial results that are disclosed
in the Company's SEC filings. Additionally, the non-GAAP
reconciliation will be available in the investor relations section of
Actuate's website at www.actuate.com.
