(1) Inputs based on quoted prices (unadjusted) in active markets for identical assets or liabilities that we have the ability to access.  Valuation of these items does not entail a significant amount of judgment.

(2) Inputs other than quoted prices included within Level 1 that are observable for the liability, either directly or indirectly.  For unsecured revolving credit facilities and unsecured term loans, fair value is determined utilizing the income valuation approach.  This valuation model takes into account the contract terms of our debt such as the debt maturity and the interest rate on the debt.  The valuation model also takes into account the creditworthiness of the Company.

(3) Inputs that are unobservable.  The Company did not use any Level 3 inputs as of June 30, 2014 and December 31, 2013.

(4) Consists of cash and marketable securities with original maturities of less than 90 days.

(5) Consists of unsecured revolving credit facilities, unsecured senior notes, senior debentures and unsecured term loans.  Does not include our capital lease obligations.

(2) Inputs other than quoted prices included within Level 1 that are observable for the asset or liability, either directly or indirectly.  For foreign currency forward contracts, interest rate swaps, cross currency swaps and fuel swaps, fair value is derived using valuation models that utilize the income valuation approach.  These valuation models take into account the contract terms, such as maturity, as well as other inputs, such as foreign exchange rates and curves, fuel types, fuel curves and interest rate yield curves. Fair value for foreign currency collar options is determined by using standard option pricing models with inputs based on the options’ contract terms, such as exercise price and maturity, and readily available public market data, such as foreign exchange curves, foreign exchange volatility levels and discount rates. All derivative instrument fair values take into account the creditworthiness of the counterparty and the Company.

(3) Inputs that are unobservable.  The Company did not use any Level 3 inputs as of June 30, 2014 and December 31, 2013.

(4) Consists of foreign currency forward contracts, foreign currency collar options, interest rate swaps and fuel swaps.  Please refer to the “Fair Value of Derivative Instruments” table for breakdown by instrument type.
