Fair Value Disclosures [Abstract]

FAIR VALUE MEASUREMENTS

FAIR VALUE MEASUREMENTS

Assets and liabilities recorded at fair value in the consolidated balance sheets are categorized based upon the level of judgment associated with the inputs used to measure their fair value.  Hierarchical levels are directly related to the amount of subjectivity associated with the inputs to fair valuation of these assets and liabilities.  We are required to separately disclose assets and liabilities measured at fair value on a recurring basis, from those measured at fair value on a nonrecurring basis.  Nonfinancial assets measured at fair value on a nonrecurring basis are intangible assets and goodwill, which are reviewed for impairment annually in the fourth quarter and/or when circumstances or other events indicate that impairment may have occurred.  Determining which hierarchical level an asset or liability falls within requires significant judgment.  The following table summarizes the assets and liabilities measured at fair value in the consolidated balance sheets:

Balance at December 31, 2016	Quoted Prices in Active Markets for Identical Assets (Level 1)		Significant Other Observable Inputs (Level 2)		Significant Unobservable Inputs (Level 3)		Total

For the years ended December 31, 2016 and 2015, there were no transfers into or out of Level 1, Level 2 and Level 3.

Interest Rate Swaps

Interest rate swap financial instruments were valued using the “income approach” valuation technique.  This method used valuation techniques to convert future amounts to a single present amount.  The measurement was based on the value indicated by current market expectations about those future amounts.  We use interest rate swaps as a means of managing interest expense and floating interest rate exposure to optimal levels.

Commodity Forward Contracts

Commodity contract financial instruments were valued primarily based on prices and other relevant information observable in market transactions involving identical or comparable assets or liabilities including both forward and spot prices for commodities.  We use commodity derivative contracts for certain raw materials and energy costs such as copper, zinc, lead, electricity and natural gas to provide a measure of stability in managing our exposure to price fluctuations.

Foreign Currency Contracts

Foreign currency contract financial instruments were valued primarily based on relevant information observable in market transactions involving identical or comparable assets or liabilities including both forward and spot prices for currencies.  We enter into forward sales and purchase contracts to manage currency risk resulting from purchase and sale commitments denominated in foreign currencies.

Financial Instruments

The carrying values of cash and cash equivalents, restricted cash, accounts receivable and accounts payable approximated fair values due to the short-term maturities of these instruments. The fair value of our long-term debt was determined based on current market rates for debt of similar risk and maturities.  The following table summarizes the fair value measurements of debt and the actual debt recorded on our balance sheets:

	Fair Value Measurements
	Level 1		Level 2		Level 3		Total		Amount recorded on balance sheets
	($ in millions)
Balance at December 31, 2016	$	—	$	3,703.7	$	153.0	$	3,856.7	$	3,617.6
Balance at December 31, 2015	—		3,826.9		153.0		3,979.9		3,848.8

Nonrecurring Fair Value Measurements

In addition to assets and liabilities that are recorded at fair value on a recurring basis, we record assets and liabilities at fair value on a nonrecurring basis as required by ASC 820.  There were no assets measured at fair value on a nonrecurring basis as of December 31, 2016 and 2015.
