Investments [Abstract]
Investment	The Company SERP utilizes a rabbi trust, and therefore, assets in the SERP portfolio are subject to creditor claims in the event of bankruptcy. We recognize SERP investment assets on the balance sheet at current fair value. A SERP liability of the same amount is recorded on the balance sheet representing an obligation to distribute SERP funds to participants. The SERP investment assets are classified as trading, and accordingly, realized and unrealized gains and losses are recognized in income in the Other Income (Expense) category. Adjustments made to revalue the SERP liability are also recognized in income as selling and administrative expenses and offset valuation adjustments on SERP investment assets.
