In pure N=4 Poincaré supergravity, all extremal spherically symmetric attractors (constant or non-constant moduli) preserve 1/4 supersymmetry for generic charges with I4>0; non-BPS attractors cannot occur.

Supersymmetry and Attractors in N = 4 Supergravity: The Superconformal Approach
In pure N=4 Poincaré supergravity, all extremal spherically symmetric attractors (constant or non-constant moduli) preserve 1/4 supersymmetry for generic charges with I4>0; non-BPS attractors cannot occur.
