ActivIdentity Reports Second Quarter Fiscal 2009 Financial Results

Market Wire, May, 2009

1.  Amortization of acquired intangible assets -- In accordance with GAAP,
    we amortize intangible assets acquired in connection with acquisitions
    over the estimated useful lives of the assets.  We exclude these
    amortization costs in our non-GAAP financial measures because they (i)
    result from prior acquisitions, rather than the ongoing operating
    performance of our business, and (ii) absent additional acquisitions,
    are expected to decline over time as the remaining carrying amounts of
    these assets are amortized.  We believe excluding these costs helps
    investors compare our financial performance with that of other
    companies with different acquisition histories.  However, as with
    impairment charges, we recognize that amortization costs provide a
    helpful measure of the financial impact and performance of prior
    acquisitions and investors should consider our non-GAAP financial
    measures in conjunction with our GAAP financial results that include
    amortization costs.

2.  Stock based compensation -- We exclude stock based compensation expense
    associated with stock options and stock granted to employees and
    non-executive directors in our non-GAAP financial measures.  While
    stock based compensation is a significant component of our expenses, we
    believe that investors wish to be able to exclude the effects of stock
    based compensation expenses in comparing our financial performance with
    that of other companies.

3.  Restructuring and severance -- We exclude restructuring and severance
    in our non-GAAP financial measures because these costs are unrelated to
    our ongoing operations.  We believe excluding restructuring and
    severance expenses help investors compare our operating performance
    with that of other companies.  We recognize, however, that
    restructuring and severance will impact cash flows and that we and
    investors should carefully consider the impact of these costs on future
    cash flows.
