DESCRIPTION:We explore the possibility that the distinct patterns observed
  in fermion masses and mixings may be due to a minimally-broken U(2) flavo
 r symmetry giving rise to an accidental U(2)^5 symmetry in the Yukawa coup
 lings of the charged fermions. In model-independent analysis we find that 
 the selection rules of the U(2) symmetry enhances the importance of charge
  lepton flavor violation as a probe for new physics. I will also present a
 n economical realization of the framework with a renormalizable model\, wh
 ich links all flavor hierarchies to a single hierarchy of scales at high e
 nergies. The model has a rich phenomenology with promising signatures\, es
 pecially in the context of K and B meson physics.
