Fair Value of Financial Instruments
Fair Value of Financial Instruments
The current authoritative guidance on fair value clarifies the definition of fair value, prescribes a framework for measuring fair value, establishes a fair value hierarchy based on the inputs used to measure fair value, and expands disclosures about the use of fair value measurements. Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date.
The valuation techniques required by the current authoritative literature are based upon observable and unobservable inputs. Observable inputs reflect market data obtained from independent sources, while unobservable inputs reflect internal market assumptions. These two types of inputs create the following fair value hierarchy:
Level 1—Quoted prices for identical instruments in active markets.
Level 2—Quoted prices for similar instruments in active markets; quoted prices for identical or similar instruments in markets that are not active; and model-derived valuations whose inputs are observable or whose significant value drivers are observable.
Level 3—Significant inputs to the valuation model are unobservable.
The following section describes the valuation methodologies used by the Company to measure its financial instruments at fair value.
Investments in marketable securities—The Company's investments in marketable securities represent investments held in a common collective trust ("CCT") that primarily invests in fixed income securities which are used to pay benefits under a nonqualified supplemental executive retirement plan for certain executives and highly compensated employees. Investments in a collective investment vehicle are valued by multiplying the investee company's net asset value per share with the number of units or shares owned at the valuation date as determined by the investee company. Net asset value per share is determined by the investee company's custodian or fund administrator by deducting from the value of the assets of the investee company all of its liabilities and dividing the resulting number by the outstanding number of shares or units. Investments held by the CCT, including collateral invested for securities on loan, are valued on the basis of valuations furnished by a pricing service approved by the CCT's investment manager, which determines valuations using methods based on market transactions for comparable securities and various relationships between securities which are generally recognized by institutional traders, or at fair value as determined in good faith by the CCT's investment manager. The fair value of these securities is included within other current assets and deferred charges and other noncurrent assets on the consolidated balance sheet.
Derivative financial instruments and hedging activities—In order to manage its exposure to commodity pricing, foreign currency risk and interest rate risk on debt, the Company periodically utilizes commodity, foreign currency and interest rate derivatives, which are considered Level 2 instruments. As discussed further in Note 7, the Company has outstanding commodity forward contracts that were entered into to hedge forecasted purchases of copper and zinc, as well as outstanding foreign currency forward contracts that were entered into to hedge forecasted transactions denominated in a foreign currency. Commodity derivatives are valued based on prices of futures exchanges and recently reported transactions in the marketplace. During the fiscal year ended March 31, 2014 ("fiscal 2014"), the Company entered into five interest rate swaps. These swaps are valued based on future LIBOR rates and the established fixed rate is based primarily on quotes from banks. Foreign currency derivatives are valued based on observable market transactions of spot currency rates and forward currency prices.
Long-term Debt—The fair value of the variable-rate long-term debt is calculated based on current market rates for debt of the same risk and maturities. The fair value of the fixed-rate debt is based on market quotes for each issuance. The Company has considered these to be Level 2 instruments.
The following table sets forth by level within the fair value hierarchy the Company's financial assets and liabilities that are measured at fair value on a recurring basis:
