Risks and Uncertainties [Abstract]
Financial Instruments with Concentrations of Credit Risk	FINANCIAL INSTRUMENTS WITH CONCENTRATIONS OF CREDIT RISK The primary customer of our Government Operations segment is the U.S. Government, including some of its contractors. Our Commercial Operations segment's major customers are large utilities. These concentrations of customers may impact our overall exposure to credit risk, either positively or negatively, in that our customers may be similarly affected by changes in economic or other conditions. In the years ended December 31, 2022, 2021 and 2020, U.S. Government contracts accounted for approximately 76%, 76% and 77% of our total consolidated revenues, respectively. Accounts receivable due directly or indirectly from the U.S. Government represented 68% and 68% of net receivables at December 31, 2022 and 2021, respectively. In the years ended December 31, 2022, 2021 and 2020, revenues from large utility customers accounted for approximately 14%, 14% and 13% of our total consolidated revenues, respectively. Accounts receivable due directly from large utility customers represented 15% and 18% of net receivables at December 31, 2022 and 2021, respectively. See Note 15 for additional information about our major customers. We believe that our provision for possible losses on uncollectable accounts receivable is adequate for our credit loss exposure. At December 31, 2022 and 2021, the allowances for possible losses that we deducted from Accounts receivable – trade, net on our consolidated balance sheets were $0.2 million.
