2.       Based on your description of Annual Contract Value on page 22, this
measure appears to
         meet the definition of a Non-GAAP measure. Tell us how you considered
Reg 10(e) of
         Regulation S-K. Please also apply this comment to your Annual Spend
measure disclosed
         on page 35 of your Form 10-KT.

3.       We note that your measure of free cash flow excludes acquisition
related payments. Tell
         us how you considered Item 10(e)(1)(ii)(A) of Regulation S-K, which
prohibits the
         exclusion of charges or liabilities that require, or may require, cash
settlement from a
         liquidity measure. Please explain or revise to remove such adjustment.
Cash Balance Sheet and Cash Flows, page 29

4.       Where you present and discuss free cash flow, also present and discuss
its most directly
         comparable GAAP financial measure, cash provided by (used in)
operating activities,
         with equal or greater prominence. Refer to Item 10(e)(1)(i) of
Regulation S-K.
        We remind you that the company and its management are responsible for
the accuracy
and adequacy of their disclosures, notwithstanding any review, comments, action
or absence of
