Fair Value Disclosures [Abstract]

FAIR VALUE MEASUREMENTS

FAIR VALUE MEASUREMENTS

Fair value is defined as the price at which an asset could be exchanged in a current transaction between knowledgeable, willing parties or the amount that would be paid to transfer a liability to a new obligor, not the amount that would be paid to settle the liability with the creditor.  Where available, fair value is based on observable market prices or parameters or derived from such prices or parameters.  Where observable prices or inputs are not available, valuation models are applied.  These valuation techniques involve some level of management estimation and judgment, the degree of which is dependent on the price transparency for the instruments or market and the instruments’ complexity.

Assets and liabilities recorded at fair value in the condensed balance sheets are categorized based upon the level of judgment associated with the inputs used to measure their fair value.  Hierarchical levels, defined by ASC 820 “Fair Value Measurements and Disclosures” (ASC 820) are directly related to the amount of subjectivity associated with the inputs to fair valuation of these assets and liabilities, and are as follows:

Level 1 — Inputs were unadjusted, quoted prices in active markets for identical assets or liabilities at the measurement date.

Level 2 — Inputs (other than quoted prices included in Level 1) were either directly or indirectly observable for the asset or liability through correlation with market data at the measurement date and for the duration of the instrument’s anticipated life.

Level 3 — Inputs reflected management’s best estimate of what market participants would use in pricing the asset or liability at the measurement date.  Consideration was given to the risk inherent in the valuation technique and the risk inherent in the inputs to the model.

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 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.  We evaluate our hierarchy disclosures each quarter.  The following table summarizes the assets and liabilities measured at fair value in the condensed balance sheets:

For the three months ended March 31, 2013, there were no transfers into or out of Level 1 and Level 2.

The following table summarizes the activity for our earn out liability measured at fair value using Level 3 inputs:

	March 31,

	($ in millions)
Balance at beginning of year	$	42.0		$	49.0
Settlements	(23.2		)	(18.5		)
Unrealized losses included in other expense	2.2			2.6
Balance at end of period	$	21.0		$	33.1

Interest Rate Swaps

The fair value of the interest rate swaps was included in other assets and long-term debt as of March 31, 2013, December 31, 2012 and March 31, 2012.  These 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

The fair value of the commodity forward contracts was classified in other current assets and accrued liabilities as of March 31, 2013, December 31, 2012 and March 31, 2012, with unrealized gains and losses included in accumulated other comprehensive loss, net of applicable taxes.  These 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 forward 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

We had no fair value of foreign currency contracts as of March 31, 2013, December 31, 2012 and March 31, 2012.  The gains and losses of foreign currency contracts were included in selling and administration expense as these financial instruments do not meet the criteria to qualify for hedge accounting.  These 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 foreign currencies.  We enter into forward sales and purchase contracts to manage currency risk resulting from purchase and sale commitments denominated in foreign currencies (principally Canadian dollar and Australian dollar).

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 condensed balance sheets:

	Fair Value Measurements
	Level 1		Level 2		Level 3		Total		Amount recorded on balance sheets
	($ in millions)
Balance at March 31, 2013	$	—	$	591.0	$	153.0	$	744.0	$	701.5
Balance at December 31, 2012	—		605.1		153.0		758.1		713.7
Balance at March 31, 2012	—		403.6		161.0		564.6		535.6

Earn Out

The fair value of the earn out associated with the SunBelt acquisition was estimated using a probability-weighted discounted cash flow model.  This fair value measurement is based on significant inputs not observed in the market.  Key assumptions in determining the fair value of the earn out include the discount rate and cash flow projections for the year ended December 31, 2013.

For the three months ended March 31, 2013 and 2012, we paid $23.2 million and $18.5 million, respectively, for the earn out related to the 2012 and 2011 SunBelt performance.  The earn out payments for the three months ended March 31, 2013 and 2012 included $17.1 million and $15.3 million, respectively, that were recognized as part of the original purchase price.  The $17.1 million and $15.3 million are included as a financing activity in the statement of cash flows.

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 March 31, 2013, December 31, 2012 and March 31, 2012.
