   1.                                                   We note your proposed
revised disclosures in response to prior comment 3. While we
                                                        acknowledge that you
have quantified the percentage change in your various revenue
                                                        streams, your proposed
disclosure does not quantify the underlying factors that
                                                        contributed to the
change in your lease license license, perpetual license, service or
                                                        maintenance revenues.
For example, you state that the increase in lease license revenue
                                                        was driven by growth in
existing multi-year licenses and a shift toward multi-year lease
                                                        products from annual
product sales. Please further revise to quantify the underlying
                                                        factors that
contributed to the change in each revenue stream. Also, refrain from using
                                                        terms such as
"primarily" in lieu of providing more specific quantitative disclosure. Refer
                                                        to Item 303(b) of
Regulation S-K.
