  In this paper we reconsider the derivation of anomaly mediated supersymmetry
breaking. We work in a general formalism where the F-term of the conformal
compensator superfield is arbitrary. This allows for a continuous interpolation
between the original derivation and a more recent Dine-Seiberg derivation of
anomaly mediation. We show that the physical soft parameters are independent of
the compensator F-term and results of two formalisms agree. Finally, we discuss
the role of supersymmetric and non-supersymmetric thresholds in the effective
low energy Lagrangian as well as the effects of explicit small mass parameters
(such as mu-term) on the superpartner spectrum.
