The investment in convertible debenture was equivalent to 24 per cent additional equity stake in the BORL. Sources said, if BPCL converts the remaining 11 per cent of convertible debentures to equity, its holding will increase to 74 per cent given that OQ has not shown interest in increasing stake in the BORL by putting in additional equity. This will leave 26 per cent equity with OQ that the company will negotiate to buy to complete 100 per cent acquisition of Bina Refinery.
