Derivative Instruments and Hedging Activities Disclosure [Abstract]

DERIVATIVE FINANCIAL INSTRUMENTS

DERIVATIVE FINANCIAL INSTRUMENTS

We are exposed to market risk in the normal course of our business operations due to our purchases of certain commodities, our ongoing investing and financing activities, and our operations that use foreign currencies.  The risk of loss can be assessed from the perspective of adverse changes in fair values, cash flows and future earnings.  We have established policies and procedures governing our management of market risks and the use of financial instruments to manage exposure to such risks.  ASC 815 required an entity to recognize all derivatives as either assets or liabilities in the statement of financial position and measure those instruments at fair value.  We use hedge accounting treatment for substantially all of our business transactions whose risks are covered using derivative instruments.  In accordance with ASC 815, we designate commodity forward contracts as cash flow hedges of forecasted purchases of commodities and certain interest rate swaps as fair value hedges of fixed-rate borrowings.  We do not enter into any derivative instruments for trading or speculative purposes.

Energy costs, including electricity used in our Chlor Alkali Products segment, and certain raw materials and energy costs, namely copper, lead, zinc, electricity, and natural gas used primarily in our Winchester and Chemical Distribution segments, are subject to price volatility.  Depending on market conditions, we may enter into futures contracts and put and call option contracts in order to reduce the impact of commodity price fluctuations.  The majority of our commodity derivatives expire within one year.  Those commodity contracts that extend beyond one year correspond with raw material purchases for long-term fixed-price sales contracts.

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).  All of the currency derivatives expire within one year and are for United States dollar equivalents.  Our foreign currency forward contracts do not meet the criteria to qualify for hedge accounting.  At December 31, 2012 and 2011, we had no forward contracts to buy or sell foreign currencies.

In March 2010, we entered into interest rate swaps on $125 million of our underlying fixed-rate debt obligations, whereby we agreed to pay variable rates to a counterparty who, in turn, pays us fixed rates.  The counterparty to these agreements is Citibank.  In October 2011, we entered into $125 million of interest rate swaps with equal and opposite terms as the $125 million variable interest rate swaps on the 2016 Notes.  We have agreed to pay a fixed rate to a counterparty who, in turn, pays us variable rates.  The counterparty to this agreement is also Citibank.  The result was a gain of $11.0 million on the $125 million variable interest rate swaps, which will be recognized through 2016.  As of December 31, 2012, $8.4 million of this gain was included in long-term debt.  In October 2011, we de-designated our $125 million interest rate swaps that had previously been designated as fair value hedges.  The $125 million variable interest rate swaps and the $125 million fixed interest rate swaps do not meet the criteria for hedge accounting.  All changes in the fair value of these interest rate swaps are recorded currently in earnings.

In 2001 and 2002, we entered into interest rate swaps on $75 million of our underlying fixed-rate debt obligations, whereby we agreed to pay variable rates to a counterparty who, in turn, paid us fixed rates.  The counterparty to these agreements was Citibank.  In January 2009, we entered into a $75 million fixed interest rate swap with equal and opposite terms as the $75 million variable interest rate swaps on the 2011 Notes.  We agreed to pay a fixed rate to a counterparty who, in turn, paid us variable rates.  The counterparty to this agreement was Bank of America, a major financial institution.  The result was a gain of $7.9 million on the $75 million variable interest rate swaps, which was recognized through 2011.  In January 2009, we de-designated our $75 million interest rate swaps that had previously been designated as fair value hedges.  The $75 million variable interest rate swaps and the $75 million fixed interest rate swap did not meet the criteria for hedge accounting.  All changes in the fair value of these interest rate swaps were recorded currently in earnings.

Cash Flow Hedges

ASC 815 requires that all derivative instruments be recorded on the balance sheet at their fair value.  For derivative instruments that are designated and qualify as a cash flow hedge, the change in fair value of the derivative is recognized as a component of other comprehensive loss until the hedged item is recognized into earnings.  Gains and losses on the derivatives representing hedge ineffectiveness are recognized currently in earnings.

We had the following notional amount of outstanding commodity forward contracts that were entered into to hedge forecasted purchases:

	December 31,
	2012		2011
	($ in millions)
Copper	$	53.6	$	52.1
Zinc	6.3		7.3
Lead	48.3		37.9
Natural gas	6.0		8.3

As of December 31, 2012, the counterparty to $69.0 million of these commodity forward contracts was Wells Fargo, a major financial institution.

We use cash flow hedges for certain raw material 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 associated with forecasted purchases of raw materials and energy used in our manufacturing process.  At December 31, 2012, we had open positions in futures contracts through 2017.  If all open futures contracts had been settled on December 31, 2012, we would have recognized a pretax gain of $7.6 million.

If commodity prices were to remain at December 31, 2012 levels, approximately $3.1 million of deferred gains would be reclassified into earnings during the next twelve months.  The actual effect on earnings will be dependent on actual commodity prices when the forecasted transactions occur.

Fair Value Hedges

For derivative instruments that are designated and qualify as a fair value hedge, the gain or loss on the derivative as well as the offsetting loss or gain on the hedged item attributable to the hedged risk are recognized in current earnings.  We include the gain or loss on the hedged items (fixed-rate borrowings) in the same line item, interest expense, as the offsetting loss or gain on the related interest rate swaps.  As of December 31, 2012 and 2011, the total notional amount of our interest rate swaps designated as fair value hedges were zero and $80.8 million, respectively.

In June 2012, we terminated $73.1 million of interest rate swaps with Wells Fargo that had been entered into on the SunBelt Notes in May 2011. The result was a gain of $2.2 million which will be recognized through 2017. As of December 31, 2012, $1.8 million of this gain was included in long-term debt. In March 2012, Citibank terminated $7.7 million of interest rate swaps on our industrial revenue bonds due in 2017. The result was a gain of $0.2 million, which would have been recognized through 2017. In June 2012, the industrial revenue bonds were redeemed by us, and as a result, the remaining $0.2 million deferred gain was recognized in interest expense during 2012. In April 2010, Citibank terminated $18.9 million of interest rate swaps on our industrial revenue bonds due in 2016.  The result was a gain of $0.4 million, which would have been recognized through 2016.  In September 2010, the industrial revenue bonds were redeemed by us, and as a result, the remaining $0.3 million gain was recognized in interest expense during 2010.

We use interest rate swaps as a means of managing interest expense and floating interest rate exposure to optimal levels.  These interest rate swaps are treated as fair value hedges.  The accounting for gains and losses associated with changes in fair value of the derivative and the effect on the consolidated financial statements will depend on the hedge designation and whether the hedge is effective in offsetting changes in fair value of cash flows of the asset or liability being hedged.

Financial Statement Impacts

We present our derivative assets and liabilities in our consolidated balance sheets on a net basis.  We net derivative assets and liabilities whenever we have a legally enforceable master netting agreement with the counterparty to our derivative contracts.  We use these agreements to manage and substantially reduce our potential counterparty credit risk.

The following table summarizes the location and fair value of the derivative instruments on our consolidated balance sheets.  The table disaggregates our net derivative assets and liabilities into gross components on a contract-by-contract basis before giving effect to master netting arrangements:

Credit Risk and Collateral

By using derivative instruments, we are exposed to credit and market risk.  If a counterparty fails to fulfill its performance obligations under a derivative contract, our credit risk will equal the fair-value gain in a derivative.  Generally, when the fair value of a derivative contract is positive, this indicates that the counterparty owes us, thus creating a repayment risk for us.  When the fair value of a derivative contract is negative, we owe the counterparty and, therefore, assume no repayment risk.  We minimize the credit (or repayment) risk in derivative instruments by entering into transactions with high-quality counterparties.  We monitor our positions and the credit ratings of our counterparties and we do not anticipate non-performance by the counterparties.

Based on the agreements with our various counterparties, cash collateral is required to be provided when the net fair value of the derivatives, with the counterparty, exceed a specific threshold.  If the threshold is exceeded, cash is either provided by the counterparty to us if the value of the derivatives is our asset, or cash is provided by us to the counterparty if the value of the derivatives is our liability.  As of December 31, 2012, the amount recognized in other current assets for cash collateral provided by counterparties to us was $0.1 million.  As of December 31, 2011, the amount recognized in accrued liabilities for cash collateral provided by us to counterparties was $3.9 million.  In all instances where we are party to a master netting agreement, we offset the receivable or payable recognized upon payment of cash collateral against the fair value amounts recognized for derivative instruments that have also been offset under such master netting agreements.
