The rebrand of the strategy, which is managed by Simon Murphy, "more accurately reflects" his approach to asset allocation, which is "wholly unconstrained" by sectors or market cap, the firm said.
VT Tyndall Unconstrained UK Income will remain a high-conviction, concentrated portfolio of between 30 to 40 UK companies, with an active share target above 80%, which currently sits at 89.4%.

Although the fund is not constrained by a benchmark, it refers to the FTSE All-Share for reference purposes, Tyndall noted.
Murphy said: "When I took over the fund nearly four years ago, I was determined to run a UK income strategy that was markedly different to those of my peers. Cognisant of the highly concentrated nature of the UK stock market, I deliberately seek to diversify further down the market cap spectrum, with no constraints at all as to sector or economic group exposures.
"Specifically, I aim to deliver a true actively managed fund, significantly differentiated from traditional benchmarks. This approach has served our clients well so far, in some of the more challenging market environments of my career."

Theresa Russell, Tyndall's head of distribution, added the fund's new name describes "much more accurately" what Murphy is trying to achieve, "namely sustainable yield and dividend growth from a select group of businesses, regardless of where they might sit within the UK market".
According to data from FE Analytics, the fund is up 15.5%, 25.6% and 35.7% over the last one, three and five years, respectively.
