In the examiners mark scheme and BPP they don’t round off the DF to 3 decimal places as we are used to,instead they use the full figures. For eg (1+.09)^-1 = 0.917….. If we use the answers to 3dp we get a whole different answer where the conclusion would be not to go ahead with the acquisition as the premium paid would be greater than the synergy benefits. So do we always have to use full figures or can we round it off ?
