The defining feature of scalar sequestering is that the minimal supersymmetric standard model squark and slepton masses as well as all entries of the scalar Higgs mass matrix vanish at some high scale. This ultraviolet boundary condition--scalar masses vanish while gaugino and Higgsino masses are unsuppressed--is independent of the supersymmetry breaking mediation mechanism. It is the result of renormalization group scaling from approximately conformal strong dynamics in the hidden sector. We review the mechanism of scalar sequestering and prove that the same dynamics which suppresses scalar soft masses and the B{sub {mu}} term also drives the Higgs soft masses to -|{mu}|{sup 2}. Thus the supersymmetric contribution to the Higgs mass matrix from the {mu} term is exactly canceled by the soft masses. Scalar sequestering has two tell-tale predictions for the superpartner spectrum in addition to the usual gaugino mediation predictions: Higgsinos are much heavier ({mu} > or approx. TeV) than scalar Higgses (m{sub A}{approx}few hundred GeV), and third generation scalar masses are enhanced because of new positive contributions from Higgs loops.
