Where a critical ICT third-party service provider refuses to endorse recommendations, based on a divergent approach from the one advised by the Lead Overseer, and such a divergent approach may adversely impact a large number of financial entities, or a significant part of the financial sector, and individual warnings issued by competent authorities have not resulted in consistent approaches mitigating the potential risk to financial stability, the Lead Overseer may, after consulting the Oversight Forum, issue non-binding and non-public opinions to competent authorities, in order to promote consistent and convergent supervisory follow-up measures, as appropriate.
