Accounting Policies [Abstract]
Allowances for Credit Losses	Allowances for Credit Losses The Company closely monitors accounts and notes receivable balances and estimates the allowance for credit losses. These estimates are based on historical collection experience and other factors, including those related to current market conditions and events. The Company’s allowance s for accounts and notes receivable have not historically been material. The Company also monitors its off-balance sheet exposures under its letters of credit, surety bonds and lease guarantees. None of these arrangements has or is likely to have a material effect on the Company’s results of operations, financial condition, revenues, expenses or liquidity.
