This document is an update of FISHSERIES/2017/MAY/SWG-DEM/11, which provides the specifications for the 2017 Reference Case (RC) assessment model. Non-trivial changes made to the 2017 model and specifications have been retained in track changes to ease their identification by the reader. These changes relate to the mortality-at-age vectors used and the methodology for incorporating proportion-at-length data into the negative log-likelihood. More details on these changes are provided in MARAM/IWS/2018/Hake/P2. Note that this document is a minor revision of the one presented at the 2018 workshop, containing a correction to a typo in the original equation 14.
