Risks and Uncertainties [Abstract] |
Concentration of Credit Risk | Note 12. Concentration of Credit Risk Financial instruments that potentially subject the Company to concentrations of credit risk consist principally of cash and cash equivalents, short-term investments and accounts receivable. The Company maintains cash and cash equivalents with various financial institutions. At times such investments may be in excess of FDIC insurance limits. As disclosed in Note 9, a significant portion of the Company's business is the production of military and industrial electronic equipment for use by the U.S. and foreign governments and certain industrial customers. The related accounts receivable balance, as a percentage of the Company's total trade accounts receivable balance, was 76.3% represented by four customers at June 30, 2021 and 53.9% represented by two customers at June 30, 2020. Although the Company's exposure to credit risk associated with nonpayment of these concentrated balances is affected by the conditions or occurrences within the U.S. and foreign governments, the Company believes that its trade accounts receivable credit risk exposure is limited. The Company performs ongoing credit evaluations of its customer's financial conditions and requires collateral, such as progress payments, in certain circumstances. The Company establishes an allowance for doubtful accounts based upon factors surrounding the credit risk of specific customers, historical trends and other information.
