(1) In the reconciliation schedule above, (i) all adjustments to IFRS revenue data reflect the exclusion of the deferred revenue adjustment; (ii) all adjustments to IFRS operating income data reflect the exclusion of the amortization of acquired intangibles, other operating income and expense, net, and stock-based compensation expense; and (iii) all adjustments to IFRS net income data reflect the combined effect of these adjustments.

(2) The adjusted percentage increase (decrease) compares adjusted measures for the two different periods. In the event there is an adjustment to the relevant measure for only one of the periods under comparison, the adjusted increase (decrease) compares the adjusted measure to the relevant IFRS measure.
