[1] During fiscal 2011 and 2010, the fair value of the SMS element of point product arrangements totaled $2.1 million and $0.7 million, respectively and was presented in the consolidated statements of operations as services and other revenue. Effective July 1, 2011, the fee attributable to the SMS in point product arrangements is no longer separable since we are unable to establish VSOE of fair value, and as a result, is included within ratable revenue.

[2] Effective July 1, 2011, the total combined arrangement fee (which includes the fee attributable to SMS) for point product arrangements with enhanced SMS is recognized on a ratable basis.
