Standard Life has once again called on former members who have yet to claim their shares following the group's 2006 stock market listing to get in touch.

Some 222,000, about 9%, have still to come forward to collect 83 million shares, collectively worth £262m at yesterday's closing price of 316.25p. This equates to a holding of 3.9%.

Most shareholders are also entitled to a dividend payment on May 31 and bonus shares on July 10.

A further 20,000 former members have still not come forward to receive cash entitlements totalling £18m.

One member in Glasgow has 36,614 shares worth £115,151, the second-largest shareholding so far unclaimed. Another, in Edinburgh, has failed to claim shares worth nearly £73,000, the company disclosed yesterday.

The number of former members who have not claimed has fallen from 350,000 when the company floated on July 10. About 7000 a month are still coming forward, following a number of direct mailings. Standard Life said yesterday it wants that number to increase over the coming year.

"We believe the former members who have yet to come forward still reside at the addresses on our records," a spokesman commented.

"Anyone who thinks they may have unclaimed shares or cash is asked to call Standard Life on 0845 275 3000."

Claimants must validate their personal and policy details in writing before the assets are released.

Unclaimed shares are currently sitting in the company's Unclaimed Asset Trust, The deadline for claiming cash and shares is July 10, 2016. After that, Standard Life said it will use the proceeds of the trust "in a number of ways", including giving money to charity.

Standard Life's outgoing chairman, Sir Brian Stewart, said: "In a perfect world these former members would be reunited with their shares or cash by the time I stand down. Whilst this is not going to happen, I would urge any- one who thinks they may have an entitlement to contact the company. It is not in our interest, nor theirs, for these assets to be sitting unclaimed."
