  • Manages potential risk through strict portfolio construction rules, promoting diversification and controlling tracking error
  • Applies multiple cost reduction methods that seeks to maximize liquidity and reduce portfolio slippage (liquidity filters, incorporating bid-ask into the optimization, restricting turnover and trade execution)
  • The strategy is fully invested at all times and can be customized to client-specific risk-return objectives
  • Universe: benchmark securities
  • Duration: +/- 0.1 yr relative to benchmark duration
  • Maximum issuer: +1% relative to benchmark exposure
