The Barclays Global Investors (BGI) Fission International Equity Index Fund, which made up 8 per cent of BISF, had been removed due to operational constraints imposed by BGI, van Eyk said.
A BGI spokesperson said the Fission product had reached capacity.
All index holdings in BISF had been consolidated into the Macquarie True Index International Shares Fund, van Eyk said.
The mandate towards the Walter Scott Global Equity Fund has also been reduced by 5 per cent. A new mandate has been awarded to the Legg Mason Global Value Equity Trust (Global Currents) following an international equities review.
"The inclusion of Global Currents at this point will add to the portfolio's value tilt without significantly eroding portfolio quality," van Eyk product manager Jacqui Lemon said.
Overall, the BISF had a 27 per cent weighting to the T Rowe Price Global Equity Fund, 20 per cent to the Walter Scott product, 20 per cent to the Arrowstreet Global Equity Fund, 13 per cent to Global Currents, 10 per cent to the Aberdeen International Equity Fund and 10 per cent to the Macquarie True Index International Shares Fund.
