An insurance giant has delisted its American shares after selling its insurance operations across the pond.

Norwich-headquartered Aviva sold its US insurance business in 2013 and no longer saw the need to have a listing on the New York Stock Exchange.

The EDP/EADT Top 100 company said its trading volumes in America were low, under 5% of its overall trading, and so it saw the need to focus on its home market.

The last day of trading of its American Depository Shares is expected to be December 22.

Aviva Investors Americas LLC, an investment adviser service, will continue to operate.

Aviva has been on the New York exchange since 2009 when it was seen as part of the group's global development plan as well as providing an opportunity for US employees to invest in the company.

Aviva sold Aviva USA to life insurance group Athene Holding for $1.8bn (£1.1bn) in 2013.
