Risks and Uncertainties [Abstract]
Concentrations of Credit Risk	Note 6. 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 10, Financial Derivatives, for a discussion of the Company’s credit risk relating to financial derivative instruments, and Note 25, Segments and Geographic Information, for a discussion of the Company’s customer concentration.
