This paper discusses in depth the feasibility of imposing structural remedies in an ex post context, drawing from experiences in other areas including self-initiated private break-ups, break-ups and structural remedies in non-merger cases, and experiences with break-ups and structural separation in regulated industries. It was prepared as a background note for discussions on disentangling consummated mergers held during the June 2022 session of the OECD Competition Committee.
