27. Appendix A: Explanation
of Net Revenue
Net Revenue Referred to in Slide Entitled “Quarterly Results-Net Revenue”
Net revenue represents total revenue net of hardware costs that are passed through to our customers.
We believe total revenues net of hardware costs more accurately reflects our core business, which is
the provision of software solutions and services, and provides transparency to our investors. It is also
the same measure used by our management to evaluate the competitiveness and development of our
business.
Reconciliation of Net Revenue to GAAP Revenue

28. Appendix B: Explanation
of Adjusted EPS
Adjusted EPS Referred to in Slide Entitled “Quarterly Results-EPS”
Adjusted EPS excludes certain non-cash expenses and income, including share-based compensation
expenses, amortization of acquired intangible assets, other operating income, and gain or loss from
discontinued operations. We believe that these non-GAAP financial measures provide meaningful
supplemental information regarding our performance and liquidity by excluding certain non-cash
expenses and income that may not be indicative of our operating performance from a cash
perspective. We believe that both management and investors benefits from referring to this additional
information in assessing our performance and when planning and forecasting future periods.
