   June 30,
2011
     December 31,
2010
 

Assets

   $ 48.6       $ 48.5

   $ 14.3       $ 12.9   

Derivatives are either foreign exchange contracts recorded at fair value to hedge currency fluctuations for transactions denominated in foreign currency, interest rate swaps or commodity swaps of forecasted commodity purchases. Assets for deferred compensation programs are for programs where select employees can defer compensation until death, disability or other termination of employment.

Assets and liabilities measured at fair value using unobservable inputs require a significant degree of judgment and estimates regarding assumptions, including, but not limited to, projected future levels of income based on management's plans, as well as business trends, prospects, and market and economic conditions. As a result, changes to the fair values could have a material impact on results of operations and liquidity when realized.

Authoritative guidance on fair value measurement (ASC 820) establishes a fair value hierarchy that prioritizes the inputs to valuation techniques used to measure fair value into three levels. Level 1 inputs, the highest priority, are quoted prices in active markets for identical assets or liabilities. Level 2 inputs reflect other than quoted prices included in Level 1 that are either observable directly or through corroboration with observable market data. Level 3 inputs are unobservable inputs, due to little or no market activity for the asset or liability, such as internally-developed valuation models.

The fair value of the Company's long-term debt (including current portion) was determined from quoted market prices, where available, and from investment bankers using current interest rates considering credit ratings and the remaining terms to maturity. The fair value of long-term debt at June 30, 2011 was approximately $3,886.9 million, compared with the aggregate carrying value of $3,693.5 million. The fair value of long-term debt at December 31, 2010 was approximately $4,323.6 million compared with the aggregate carrying value of $4,228.0 million.
