Dividend distribution timing clarified for tax treatment, defining treated distributions after notice, Board order, and other cases. The amendment confines 'distributed' dividends in clauses (i)-(iii) to amounts paid within the twelve month period referenced in the related provision and adds an Explanation defining 'the sum distributed as dividends': for further distributions after a notice the aggregate of dividends within that twelve month period and dividends within three months of the notice; for cases with a Board review order the amount paid within the period the Board determines; otherwise dividends within the twelve month reference period.
