| IRS990ScheduleD/SupplementalInformationDetail/ExplanationTxt | 0 | Accounting principles generally accepted in the United States of America require the System to evaluate tax positions taken by the System and recognize a tax liability or asset if the System has taken an uncertain position that more likely than not would be sustained upon examination by the Internal Revenue Services (IRS). The System has concluded that as of December 31, 2020 and 2019, there are no uncertain positions taken or expected to be taken that would require recognition of a liability or asset or disclosure in the consolidated financial statements. The System is subject to routine audits by taxing jurisdictions; however, there are currently no audits or any tax examinations for years prior to the fiscal year ended December 31, 2017. |
