The fund invests in real asset-related companies across the capital structure, including common stocks, preferred securities, and debt. Real asset-related companies include those engaged in owning, operating or developing infrastructure projects, facilities and services, as well as REITs. Up to 40% of the fund’s assets, at the time of purchase, may be debt securities. All of the fund’s debt may be rated lower than investment grade (Ba1/BB+ or worse by S&P, Moody's, or Fitch), but no more than 10% of the fund’s managed assets may be invested in securities rated CCC+/Caa1 or lower at any time. The fund’s non-US exposure may range from 25% to 75% of its managed assets. To a limited extent, the fund also opportunistically writes calls options primarily on securities issued by real asset related companies, seeking to enhance its risk-adjusted total returns over time. The fund uses leverage.
