Final Dividend is 2 step process
1st Step– Board Proposes Final Dividend
2nd Step– Shareholders Declare Final Dividend, then it becomes debt and it must be paid in cash.
Before 2nd step board can roll back there decision but after 2nd step roll back is not possible, it can be done in exceptional case if profits were fake, dividend is illegal or company’s going concern is in danger.
Interim Dividend has only one step.
BOARD declares interim dividend and it become debt and it must be paid in cash.
so in interim dividend there is no scope to cancel dividend once declared, unless circumstances explained above.
