This group said this will pave the way for it to become a tax-friendly property authorised investment fund (Paif).
The motion was passed with 99.7% approval, meaning the £2.1 billion unit trust will merge into a specially created open-ended investment company structure at the end of August. It will be renamed the Henderson UK Property OEIC.
A Paif can be more tax efficient for certain groups, such as charities, UK pension funds, and investors using Sipps and Isas, but can only take the form of an Oeic. Henderson will pay all of the administrative costs of the conversion.
The group joins fellow asset managers Ignis, Standard Life Investments, Kames Capital and Legal & General which have all moved to a Paif structure in recent years.
The conversion also means the property fund will give quarterly instead of bi-annual payouts.
‘We believe a move to more frequent income payments will be beneficial to those investors who rely on income from the fund,’ said Martyn Bailey, head of client services at Henderson.
It has returned 10.6% in the year to the end of July, ranking it 21st out of 29 funds in the Citywire UK Physical property sector. In three years it has returned 21.9%, making it fourth best performer out of 22 funds in the Citywire sector.
