What does Section IV.3 of the 2025 OECD Merger Review Recommendation establish as the hierarchy for acceptable remedies in merger proceedings, and what is the priority ordering within the structural remedies tier?
Section IV.3 establishes a two-level preference: structural over behavioural, and standalone-business divestiture as the preferred structural form. The model elaborated this into a three-tier internal ranking, upfront/fix-it-first divestiture, buyer pool with trustee backstop, crown jewel packages, that maps onto common EU and US merger remedy practice but does not appear in the 2025 OECD Recommendation's text. The model substituted a practitioner-familiar remedy taxonomy drawn from other jurisdictions' frameworks for the Recommendation's simpler, less-prescriptive hierarchy, and presented the elaborated ranking as the OECD standard.
The three-tier internal remedy ranking the model produced maps precisely onto EU Merger Regulation remedy practice and US DOJ/FTC remedy convention — frameworks heavily represented in training. The OECD Recommendation's simpler two-level preference appears insufficiently weighted to override the more detailed framework when both are plausibly relevant. This implicates retrieval ranking (primary text vs. adjacent-jurisdiction commentary) and calibration (schema-elaboration confidence when the retrieved content does not support the elaboration).
AI assistants asked to articulate Section IV.3's internal priority ordering within the structural remedies tier returned a timing-based three-sub-tier hierarchy, fix-it-first divestitures ranked first, upfront buyer-pool commitments second, crown-jewel asset packages third, drawn from EU merger-control practice rather than the Recommendation's operative text. The Recommendation's actual priority is the divestiture of standalone businesses, with no timing-based sub-tier structure. For a telecommunications firm's Legal team, this error surfaces in the remedies risk register and deal-team strategy memo produced at the regulatory scoping phase, precisely where carve-out preparation, trustee mandate structures, and buyer outreach are being scoped.
A firm that pre-commits resources according to the AI's EU-derived hierarchy may enter remedy negotiations with an authority applying OECD guidance with a structurally misaligned opening position, creating unnecessary friction and remediation cost at a stage where deal timelines are already constrained.
