Through its multi-sector fixed-income strategy, the fund invests predominantly in US issuers with the goal of generating a high level of current income consistent with preservation of principal.

Key Features

  • Employs bond-by-bond portfolio construction with a focus on being well compensated for risks taken. We believe a disciplined process, grounded in fundamental research, enables us to achieve higher total returns with less volatility.
  • Draws on a broader investable universe to enhance portfolio construction and risk management. Expanding the universe to include high-yield bonds, bank loans and preferreds provides additional opportunities.
  • Utilizes robust, independent credit research. Our fixed-income investment process unites quantitative and qualitative analyses into historical and forward-looking models. The result is a credit rating reflective of where a company is heading.
  • Takes environmental, social and governance (ESG) factors into account, evaluating whether they impact a company's cash flow, risk profile and long-term returns.
  • Applies a macro overlay to capitalize on misunderstood industries and sectors. The overlay acts as a risk control that also considers the business cycle, geopolitical factors, inflation and real rate expectations.

Portfolio Fit

The Fund may be suitable for investors seeking current income accompanied by lower volatility over a one-year to two-year time horizon.

Performance data quoted represents past performance, which is no guarantee of future results. Current performance may be lower or higher than the performance quoted. Please refer to Important Risk Information. The principal value and return of an investment will fluctuate so that your shares, when redeemed, may be worth more or less than their original cost. Performance reflected at NAV does not include the Fund's maximum front-end sales load of 2.25%. Had it been included, the Fund's return would have been lower.
