Strategy Narrative [Text Block]	The Fund is an exchange-traded fund. The Fund seeks to achieve attractive total returns over the long-term and to maximize real returns during inflationary environments. “Real returns” are defined as total returns adjusted for the effects of inflation. The Fund pursues its objectives through investments offering exposure to “real assets,” which the Fund defines as (i) real estate, commodities, natural resources, infrastructure and gold and other precious metals; and (ii) companies that own or derive a significant portion of their value from such real assets or the production thereof. Under normal market conditions, the Fund seeks to achieve its investment objectives by allocating at least 80% of its net assets to U.S. and non-U.S. investments providing exposure to or investment in the following real asset classes: (i) real estate companies, including real estate investment trusts (“REITs”); (ii) commodities; (iii) natural resource companies; (iv) infrastructure companies; and (v) gold and other precious metals. The Fund may also invest in certain short-term fixed income securities to manage portfolio volatility. Investments offering exposure to “real assets” may include common stocks and other equity securities, preferred securities, debt securities (including convertible securities), derivatives and securities issued by exchange-traded funds and other investment vehicles. The Fund may also participate in private investments in public equity (“PIPEs”) and the initial public offering (“IPO”) market. The Fund is actively managed by the Advisor. To pursue its goal, the Advisor combines a top-down approach, focused on identifying relative value across multiple classes of real assets, with bottom- up security selection based on fundamental research concentrated at the sector-, industry-, and security-levels.When making allocation decisions, the Advisor conducts quantitative and qualitative analysis, aiming to optimize the balance between relative return potential and risk across asset classes. The goal of this process is to establish a target asset allocation for the Fund intended to meet its objectives while maintaining a risk/return profile that is consistent with the Fund’s investment objectives. In choosing investments at the asset class level, the Advisor, through its specialized investment teams, follows an active fundamental approach with respect to investments in real estate companies, natural resource companies and infrastructure companies, in each case focused on identifying what are believed to be securities possessing superior risk-adjusted return profiles. For these real asset allocations, the Advisor seeks to outperform a passive allocation to that asset class over a full market cycle. The Advisor expects the Fund to gain exposure to commodities, gold and other precious metals, and fixed income securities indirectly through investments in other exchange-traded funds (“Underlying ETFs”), some of which may be affiliated with the Advisor. The Underlying ETFs may be actively managed or may passively track the performance of an index or the value of a commodity. Some Underlying ETFs may not be registered as investment companies under the Investment Company Act of 1940 (the “1940 Act”). While the Fund is not constrained to allocate its investments among asset classes according to specific ranges, under normal circumstances the Advisor expects the Fund’s assets to be allocated to each asset class within the allocation ranges set forth in the table below. In addition, the Advisor has appointed a committee (the “Asset Allocation Committee”) consisting of a select group of the Advisor’s senior investment professionals, to periodically review the Fund’s asset allocation and allocation targets. Actual allocations may vary at any time and may move and remain outside of these ranges for a variety of reasons, including, but not limited to, changes in investment outlook, market movements, cash flows into or out of the Fund and other factors, such as that securities held within one asset class will overlap with another asset class (e.g., gold and other precious metals overlap with the commodities and natural resource companies asset classes).
