Fair Value Measurements and Derivative Instruments

Fair Market Value Measurements

Depending on the inputs, we classify each fair value measurement as follows:


•	Level 1 – based upon quoted prices for identical instruments in active markets,


•	Level 2 – based upon quoted prices for similar instruments, prices for identical or similar instruments in markets that are not active, or model-derived valuations of all of whose significant inputs are observable, and


•	Level 3 – based upon one or more significant unobservable inputs.

The following section describes key inputs and assumptions used in valuation methodologies of our assets and liabilities measured at fair value on a recurring basis:

Cash and cash equivalents, short-term notes and accounts receivable, accounts payable and other current payables – The carrying amount approximates fair value because of the short maturity of these instruments.

Long-term debt – Fair value of long-term debt, which was determined using Level 2 inputs, as of December 31, 2012 was $546.3 million versus a book value of $535.7 million. As of December 31, 2013 the fair value was $549.8 million, versus a book value of $541.6 million.

Foreign currency derivatives – Foreign currency derivatives are carried at market value using Level 2 inputs. The outstanding contracts as of December 31, 2012 and 2013 represented unrealized losses of $1.3 million and $0.1 million, respectively.

Commodity derivative contracts – Commodity derivative contracts are carried at fair value. We determine the fair value using observable, quoted natural gas and refined oil product prices that are determined by active markets and therefore classify the commodity derivative contracts as Level 2. The outstanding commodity derivative contracts represented no unrealized gains or losses as of December 31, 2012 and an unrealized gain of $0.8 million as of December 31, 2013.

Derivative Instruments

We use derivative instruments as part of our overall foreign currency and commodity risk management strategies to manage the risk of exchange rate movements that would reduce the value of our foreign cash flows and to minimize commodity price volatility. Foreign currency exchange rate movements create a degree of risk by affecting the value of sales made and costs incurred in currencies other than the US Dollar.

Certain of our derivative contracts contain provisions that require us to provide collateral. Since the counterparties to these financial instruments are large commercial banks and similar financial institutions, we do not believe that we are exposed to material counterparty credit risk. We do not anticipate nonperformance by any of the counter-parties to our instruments.

Foreign currency derivatives

We enter into foreign currency derivatives from time to time to attempt to manage exposure to changes in currency exchange rates. These foreign currency instruments, which include, but are not limited to, forward exchange contracts and purchased currency options, attempt to hedge global currency exposures such as foreign currency denominated debt, sales, receivables, payables, and purchases. Forward exchange contracts are agreements to exchange different currencies at a specified future date and at a specified rate. There was no ineffectiveness on these contracts during the twelve months ended December 31, 2012 or 2013.

In 2012 and 2013, we entered into foreign forward currency derivatives as hedges of anticipated cash flows denominated in the Mexican peso, Brazilian real, South African rand, euro and Japanese yen. These derivatives were entered into to protect the risk that the eventual cash flows resulting from such transactions will be adversely affected by changes in exchange rates between the US dollar and the Mexican peso, Brazilian real, South African rand, euro and Japanese yen. As of December 31, 2012, we had outstanding Mexican peso, Brazilian real, South African rand, euro, and Japanese yen currency contracts, with aggregate notional amounts of $183.7 million. As of December 31, 2013, we had outstanding Mexican peso, Brazilian real, South African rand, euro and Japanese yen currency contracts, with aggregate notional amounts of $138.6 million. The foreign currency derivatives outstanding as of December 31, 2013 have several maturity dates ranging from January 2014 to September 2014.

Commodity derivative contracts

We periodically enter into derivative contracts for natural gas and certain refined oil products. These contracts are entered into to protect against the risk that eventual cash flows related to these products will be adversely affected by future changes in prices. There was no ineffectiveness on these contracts during the twelve months ended December 31, 2012 or 2013. As of December 31, 2012 and 2013, we had outstanding derivative swap contracts for refined oil products with aggregate notional amounts of $31.9 million and $45.8 million, respectively. The outstanding 2013 contracts have maturity dates ranging from January 2014 to June 2014.

Net Investment Hedges

We use certain intercompany debt to hedge a portion of our net investment in our foreign operations against currency exposure (net investment hedge). Intercompany debt designated in foreign currency and designated as a non-derivative net investment hedging instrument was $20.1 million and $25.2 million as of December31, 2012 and December 31, 2013 respectively. Within our currency translation adjustment portion of other comprehensive income, we recorded a loss of $0.6 million in 2012 and a gain of $4.7 million in 2013 resulting from these net investment hedges.

The fair value of all derivatives is recorded as assets or liabilities on a gross basis in our Consolidated Balance Sheets. At December 31, 2012 and 2013, the fair values of our derivatives and their respective balance sheet locations are presented in the following table:

The location and amount of realized (gains) losses on derivatives are recognized in the Statements of Income when the hedged item impacts earnings and are as follows for the years ended 2012 and 2013:

Our foreign currency and commodity derivatives are treated as hedges and are required to be measured at fair value on a recurring basis. With respect to the inputs used to determine the fair value, we use observable, quoted rates that are determined by active markets and, therefore, classify the contracts as “Level 2”.
