[1] | (1)The fair value of our call options, designated as economic hedges, are calculated using a valuation model based on the underlying currency exchange rates and related volatility, and are classified within Level 2 of the fair value hierarchy.
[2] | (2)We maintain deferred compensation plans that allow for certain management employees to defer the receipt of compensation (such as salary, incentive compensation and commissions) until a later date based on the terms of the plans. The liability representing benefits accrued for plan participants is valued at the quoted market prices of the participants’ investment elections. The asset consists of mutual funds reflective of the participants investment selections and is valued at daily quoted market prices.
