Phoenix Group, Royal London and Scottish Widows are among those considering offers for the UK insurance business of Dutch insurance and retirement giant Aegon, according to a report in The Financial Times, a London newspaper.

Private equity groups including CVC have also shown preliminary interest in the sales process ahead of an initial bid deadline in the coming weeks, according to the report.

Goldman Sachs is running the auction process.

In December, Aegon said it will move its “head office and legal seat” to the United States.

Following completion of the re-domiciliation process, the holding company, Aegon Ltd., will be renamed Transamerica Inc., while its business units will continue to operate under their current brands.

As part of the process, Aegon said it began a strategic review of Aegon UK, including its large Edinburgh-based operations “including a potential divestment.”

Aegon UK’s asset management operations — mostly based in Edinburgh — would not be part of any divestiture, the report said.

Any sale would aim to “protect the value of our asset management fees that we’re generating in the UK,” chief executive Lard Friese said in December, according to the report.

Aegon’s UK business employs about 2,500 people.
