To complement our response to the FCA's Primary Markets Effectiveness Review, UK Finance responded in August to FTSE Russell's consultation on the potential impact on index eligibility of the FCA's proposed changes to free float and dual-class share (DCS) structure requirements. Coordination and engagement between the FCA and FTSE Russell with respect to the ongoing reform of the UK's listing rules is welcome, and key to ensuring that any relevant rule changes made by the FCA following its review are reflected effectively in the inclusion criteria for the FTSE UK Index Series.
