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, 2014, our uninsured cash balance was approximately $3.4 million. Our term loans bear a variable interest rate based on LIBOR and our primary mortgage bears interest at a variable rate based on the prime rate. See NOTE K for further detail on these instruments. These instruments expose us to interest rate risk. On our primary mortgage, for an increase of every 100 basis points, our interest obligation increases by approximately, on average, $864 per month until maturity in July 2016. An increase of 100 basis points to the interest rate on our term loans increases our interest obligation, at most, by approximately, on average, $2,512 per month while an increase of 100 basis points on our project term loan would increase the monthly interest payment by approximately $6,446. See NOTE K. If an increase to the rates on these instruments occurs, it will have an adverse effect on our operating cash flows and financial condition but we believe it would not be material.
