[1] As a result of the sale of our Speakeasy business in the second quarter of fiscal 2011, we eliminated the carrying value of the related goodwill and indefinite-lived tradenames as of the date of sale.

[2] Represents the transfer of certain definite-lived tradenames (at their net book value) to indefinite-lived tradenames following our decision to no longer phase out certain tradenames. We believe these tradenames will continue to contribute to our future cash flows indefinitely.
