Publicly-traded companies in infrastructure businesses may include energy, industrial, and utility companies. Publicly-traded companies in natural resources and/or commodities businesses may include agriculture, energy, and metals and mining companies. The Fund's allocation among these asset classes will be in proportions consistent with the Adviser's evaluation of the expected returns and risks of each asset class as well as the allocation that, in the Adviser's view, will best meet the Fund's investment objective. The Adviser's investment process relies on proprietary quantitative models as well as the Adviser's fundamental views regarding qualitative factors that may not be captured by the quantitative models. The allocations to each asset class will change over time as the Adviser's expectations of each asset class shift. The Fund's indirect holdings by virtue of investing in ETPs representing those asset classes will consist of a diversified mix of domestic and international equity securities, including emerging markets, government bonds, inflation protected securities, commodities and real estate investment trusts (REITs). The Fund may invest in ETPs that gain exposure to commodities through the use of derivatives. The Adviser considers real return to be a rate of return above the rate of inflation over a market cycle. ETPs in which the Fund invests include exchange-traded funds registered under the Investment Company Act of 1940, as amended (the 1940 Act) (Underlying ETFs), exchange traded commodity trusts; and exchange traded notes (ETNs). The Fund may invest in ETPs that are qualified publicly traded partnerships (QPTPs). In addition, the Fund ? may invest in certain ETPs that pay fees to the Adviser and its affiliates for management, marketing or other services. In addition, the Fund may invest in cash and cash equivalents or money market instruments, such as money market funds (including money market funds advised by the Adviser). Show less
