Risks And Uncertainties [Abstract]
Concentrations of Credit Risk	Note 7. Concentrations of Credit Risk Financial instruments that potentially subject the Company to concentrations of credit risk consist principally of trade receivables. The Company’s credit concentrations are limited due to the wide variety of customers and markets in which the Company’s services are sold. See Note 12, Financial Derivatives, for a discussion of the Company’s credit risk relating to financial derivative instruments, and Note 27, Segments and Geographic Information, for a discussion of the Company’s customer concentration.

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.
