Also what will be the rate if dividend is declared only for 1 year in the previous 3 years?
If no dividend is declared in past 3 years, then we have to ignore condition of average dividend rate, that means no need to calculate average and stick to it
if dividend is given in 2 years take average of 2 years as rule says take average of announced dividend rates
if it is announced in one year take that as average, “no need” to do (0+0+x) / 3
And if no dividend is declared in any of the previous 3 years. Then is company allowed to declare dividend?
Yes it is written on rules that then this condition of average dividend will not be applicable
