Barclays Global Investors Canada Ltd. has filed the preliminary prospectus for four new iUnits, a series of index funds that provide sector exposure and inflation protection, the company says. The four new funds are iUnits Materials Sector Index Fund (XMA), iUnits Income Trust Sector Index Fund (XTR), iUnits Dividend Index Fund (XDV) and iUnits Real Return Bond Index Fund (XRB). XMA will aim to replicate the performance of the S&P/TSX capped materials index, while XTR is designed to provide exposure to the Canadian income trust sector by replicating the performance of the S&P/TSX income trust index. XDV will focus on investing in stocks with higher yields and higher liquidity, and will aim to replicate the performance of the Dow Jones Canada select dividend index. XRB is designed to replicate the performance of the Scotia real-return bond index. Barclays Canada’s existing sector iUnits funds include energy (XEG), financials (XFN), gold (XGD), technology (XIT) and REITS (XRE). Advisor commissions differ with every dealer. Management fees are 0.55% for XMA and XTR, 0.5% for XDV and 0.35% for XRB.
