In this talk I will discuss about scenarios where Dark Matter (DM) particles carry baryon and lepton numbers. Clearly the baryon and lepton numbers of the DM particles can be defined only if there exists operators which connect them to the Standard Model (SM) baryons and leptons. As a result the DM particles become intimately linked to the SM particles and can be maximally asymmetric just like the baryons of the SM. We consider an initial asymmetry that is frozen in either the SM or the DM sectors and the main role of these operators is to make sure that the asymmetry is properly distributed between the SM and DM
sectors in accordance with observations. Once the mass of the DM is specified, the Wilson coefficients of these operators will be fixed by the requirement of correct transfer of the asymmetry. With the mass of DM and coefficients of these operators fixed, I will discuss possible phenomenological consequences.
