Yorkshire Building Society is set to finalise a deal to take over lossmaking rival Chelsea in the latest sign of consolidation in the UK’s troubled mutual sector. A combined Yorkshire and Chelsea would be a strong number two to market leader Nationwide. Significantly, Chelsea will use a new kind of contingent convertible, or CoCo, instrument as part of the merger deal, in a structure that will be seen by regulators, and other societies, as a model for further dealmaking in the building society sector.
