Concentration of Credit Risk


Certain financial instruments potentially subject the Company to concentrations of credit risk.  These financial instruments consist primarily of cash and accounts receivables. At December 31, 2015, the Company did not have deposits with a financial institution that exceed the FDIC deposit insurance coverage of $250,000. There is a concentration of credit risk with respect to accounts receivable due to the number of major customers.
