Affleck-Dine and thermal equilibrium

Hi, I am currently studying Cosmology on my own, and I am learning about the Affleck-Dine mechanism of baryogenesis. I understand that in this case the baryon asymmetry is generated by the decay of a supersymmetric flat direction carrying B, which is excited during inflation.

Regarding Sakharov's conditions, B and CP violation come explicitly from soft supersymmetry breaking induced terms in the Lagrangian (the so-called A-terms). However, a mention of the third Sakharov condition is nowhere to be found. How is thermal equilibrium lost in this particular model of baryogenesis?
