In this work, three such asymmetries are studied in the context of a three-Higgs-doublet model (3HDM), and it is shown that all three ${\\cal A}_{CP}$ can be as large as the current experimental limits. Of particular interest is ${\\cal A}_{CP}$ for ${\\overline B}\\to X_{s+d}\\gamma$, which is predicted to be effectively zero in the Standard Model (SM).
