        <ExplanationTxt>Accounting principles generally accepted in the United States of America require management to evaluate income tax positions taken and accrue an income tax liability if the organization has taken an uncertain position that more likely than not would not be sustained upon examination by the Internal Revenue Service. Management has evaluated the income tax positions taken and concluded that as of March 31, 2020 there are no uncertain positions taken or expected to be taken that would require accrual of a liability in the consolidated financial statements. NALC is subject to routine audits by taxing jurisdictions; however, there are currently no audits in progress for any tax periods. Management believes that NALC is no longer subject to audit for years ending prior to March 31, 2017. In addition, there have been no tax related interest or penalties for the periods presented in these financial statements. Should such penalties and interest be incurred, NALC's policy is to recognize them as administrative expenses.</ExplanationTxt>
