LONDON (Reuters) – Baillie Gifford US Growth Trust, which is fighting plans by US activist Saba Capital to shake up its board, unveiled new data on Tuesday to show it outperformed the S&P 500 Index of favorable terms for the six months to Nov. 30.

In response to Saba’s allegations of persistent underperformance, Baillie Gifford said the company’s share price and net asset value returned 40.9% and 29.4% respectively during the period, after deducting borrowings fair value.

This compared to a total return of 15.3% for the S&P 500Index in better terms, it said, rejecting Saba’s proposals to put two of its own nominees on the board as a test to “self-serving and destructive” to control the company.

Saba, founded and run by veteran Wall Street activist investor Boaz Weinstein, said last month it wanted to overhaul the boards of seven trusts over performances it said ranged from “disappointing” to to “damage”.

Weinstein said critics of his plans had misled investors who lost “huge amounts”.

He pointed to Baillie Gifford as well as Henderson Opportunities Trust, the European Smaller Companies Trust, CQS Natural Resources Growth & Income, Edinburgh Worldwide Investment Trust, Herald Investment Trust and Keystone Positive Change (KPC).

From its 2013 launch to Nov. 30, Baillie Gifford’s share price and NAV returned 169.7% and 186.1% respectively, compared to a total return of 190.5% for the best terms, after deducting borrowings at fair value.

KPC also noted on Tuesday that Glass Lewis (JO:), the independent proxy advisor, recommended that shareholders vote against Saba’s proposals at a meeting on February 3.

Glass Lewis cited a “lack of detail” and said Saba’s campaign was “more about gaining influence than about offering shareholders a timely and specific exit”, KPC said.
