This document reports progress on hake OMP revision issues identified at the last DWG meeting as requiring further attention. In particular it updates the Reference Case CMP in terms of the agreements reached at that meeting. Suggestions are made for the final set of calculations needed before a selection is made amongst CMPs at the following DWG meeting. In addition, proposals are made concerning revision of the hake-specific sections of the document governing “exceptional circumstances” for overriding an OMP TAC recommendation or bringing forward an OMP review. These include provisions relating the MSC condition concerning specification of Target and Limit Reference Points for M.paradoxus.
