The board of directors of Indian Oil Corporation will meet on Thursday to consider buyback of fully paid-up equity shares of the company, and declaration of an interim dividend for the financial year 2018-19. It may be recalled that the PSU oil company in March had rewarded its shareholders with a 1:1 bonus issue. Besides payout details, shareholders will also eye the issue size, price and mode (through open market purchase or tender route) of the buyback.
