Concentrations of Credit Risk [Abstract]
Concentrations of Credit Risk	(16) Concentrations of Credit Risk The Company's concentration with respect to trade accounts receivable is limited. The large number of customers and diversified customer base across the two segments significantly reduces the Company's credit risk. The Company also has strict policies regarding the granting of credit to customers and does not offer credit terms to those customers that do not meet certain financial criteria and other guidelines. The Company is monitoring the payment practices of customers and is reviewing credit limits more frequently and conservatively than in prior periods. No customer represented over 10% of consolidated company sales or accounts receivable as of December 31, 2012, 2011 and 2010.

The entire disclosure for any concentrations existing at the date of the financial statements that make an entity vulnerable to a reasonably possible, near-term, severe impact. This disclosure informs financial statement users about the general nature of the risk associated with the concentration, and may indicate the percentage of concentration risk as of the balance sheet date.
