[1] Gains on sale of trademarks was previously reported as other revenue. Many of the gains recorded upon formation of certain joint ventures were reversed as a result of consolidation. The gains that were not impacted by consolidation, and therefore not reversed, have been reclassified and are being presented as a separate line item above operating income.
