Amount B promised to simplify transfer pricing for routine distribution—a genuine problem consuming six-figure fees on 3% margin transactions. Instead, it haunts the international tax system as a specter of what could have been.

The ghost of transfer pricing simplification lives. It just hasn't found a body yet.
