Concentration Risk Disclosure [Text Block] | NOTE E—CONCENTRATION OF RISK Financial instruments which potentially subject the Company to risk primarily consist of cash, short-term investments, and accounts receivables. The Company maintains its cash and cash equivalents with various financial institutions, which, at times may exceed the amounts insured by the Federal Deposit Insurance Corporation. The exposure to the Company is solely dependent upon daily bank balances and the respective strength of the financial institutions. No amounts were in excess of coverage at December 31, 2019 and 2018. The Company has not incurred any losses on these accounts. The Company extends credit to customers on an unsecured basis in the normal course of business. The Company’s policy is to perform an analysis of the recoverability of its receivables at the end of each reporting period and to establish allowances where appropriate. The Company analyzes historical bad debts and contract losses, customer concentrations, and customer credit-worthiness when evaluating the adequacy of the allowances. During the year ended December 31, 2019, two customers accounted for 22% and 14% of total revenue, respectively. During the year ended December 31, 2018, three customers accounted for 27%, 14% and 13% of total revenue, respectively. Three customers accounted for 18%, 16% and 14% of total accounts receivable, respectively, as of December 31, 2019. One customer accounted for 70% of total accounts receivable, as of December 31, 2018.
