In the MSSM, the presence of CP phases can have a significant impact on the neutralino relic abundance. These phase effects are on the one hand due to shifts in the masses, on the other hand due to modifications of the couplings. Typical variations in {omega}h2 solely from modifications in the couplings are O(10%-100%)
