| Amendment Description | On May 26, 2021, Universal Corporation (the “Company”) furnished a Current Report on Form 8-K (the “Original 8-K”) that included the press release discussing its results for the quarter and fiscal year ended March 31, 2021 (the “Earnings Release”). This Current Report on Form 8-K/A amends the Original 8-K solely for the purpose of correcting a clerical error which incorrectly noted in the Adjusted Net Income and Diluted Earnings Per Share Reconciliation Table on page 6 of the Earnings Release that the Adjusted: Diluted Earnings Per Share for the fiscal year ended March 31, 2021, should have been $4.25 instead of $3.49. Other than correction of the error discussed in this Current Report on Form 8-K/A, no other changes have been made to the Original Form 8-K or the Earnings Release furnished therewith. The Adjusted Net Income and Diluted Earnings Per Share Reconciliation Table with the correct Adjusted: Diluted Earnings Per Share for the fiscal year ended March 31, 2021 of $4.25 is set forth below: |
