Risks and Uncertainties [Abstract]
Concentration of Credit Risk	NOTE B – CONCENTRATION OF CREDIT RISK We maintain the majority of our cash at one financial institution. At December 31, 2017 and 2016, our uninsured cash balance was approximately $0.8 million and $1.5 million, respectively. We do not have any outstanding loans that bear variable interest rates thus we do not have any corresponding interest rate risk.
