We study the resonantly enhanced CP-asymmetry in the decays of nearly
mass-degenerate heavy right-handed Majorana neutrinos for which different
formulae have been presented in the literature, depending on the method used to
calculate it. We consider two different techniques and show that they lead to
the same result, thereby reconciling the different approaches.
