    Network Appliance Usage of Pro forma Financials

    The Company refers to the non-GAAP financial measures cited above

supplemental information regarding the Company's operational
performance. In addition, these non-GAAP financial measures facilitate
management's internal comparisons to the Company's historical
operating results and comparisons to competitors' operating results.
We include these non-GAAP financial measures in our earnings
announcement because we believe they are useful to investors in
allowing for greater transparency with respect to supplemental
information used by management in its financial and operational
decision-making. In addition, we have historically reported similar
non-GAAP financial measures to our investors and believe that the
inclusion of comparative numbers provides consistency in our financial
reporting at this time.
