(1) The provision for income taxes may be impacted by excess tax benefits primarily resulting from vesting and exercises of equity awards. Our estimated provision for income taxes does not include the impact, if any, of unknown future exercises of employee equity awards, which could have a material impact given that a significant portion of our awards are in-the-money.
(2) Our guidance includes certain estimated changes in the fair value of the contingent consideration based on the passage of time, updated financial projections and changes in market factors used to derive the estimate. Separately, the intercompany loan associated with the Whistler Blackcomb transaction requires foreign currency remeasurement to Canadian dollars, the functional currency of Whistler Blackcomb. Our guidance excludes any forward looking change related to foreign currency gains or losses on the intercompany loans, which such change may be material.
