The present status of lattice calculations of f B, B B and SU(3) flavour breaking ratios such as is reviewed. Particular attention is devoted to systematic uncertainties, such as those arising from the lack of simulation data for dynamical quarks with realistic masses, and the related difficulties associated with chiral extrapolations. Global averages for decay constants and mixing parameters are presented (Table 1), and the procedures to obtain them are discussed in detail.
