{ital CP} asymmetries in neutral-{ital B} decays to {ital CP} eigenstates are studied in the standard model. Whereas usually one assumes a single decay amplitude which induces {ital CP} violation via {ital B}-{ital {bar B}} mixing, we investigate additional effects due to two interfering decay amplitudes. We estimate these effects in characteristic cases and suggest ways to experimentally distinguish between these two sources of asymmetries. The effects, which show up as time-integrated asymmetries at symmetric {ital e}{sup +}e{sup {minus}} colliders operating at the {Upsilon}(4{ital S}), are quite small in Kobayashi-Maskawa- (KM) allowed decays such as as {ital B}{sub {ital d}}{sup 0}{r arrow}K{sub S}{psi} and become large in KM-suppressed decays.
