Strategy [Heading]	Principal Investment Strategies
Strategy Narrative [Text Block]	The Fund is an actively managed exchange-traded fund (“ETF”) that seeks to achieve its investment objective by investing, under normal circumstances, at least 80% of its net assets, plus any borrowings for investment purposes, in dividend-paying equity securities. The Fund defines dividend-paying equity securities as securities that produced dividend income within the last rolling 12 months. The Fund usually invests in equity securities of companies with large and medium market capitalizations. The Fund invests in U.S. and non-U.S. companies. The Fund invests in U.S. and non-U.S. companies. The Fund invests in value equity securities, an investment strategy that emphasizes buying equity securities that appear to be undervalued. The Fund seeks to achieve its objective by (1) creating an actively managed portfolio of equity securities, and (2) selling call options on the equity securities in the Fund’s portfolio. The Fund is managed in a way that seeks, under normal circumstances, to provide monthly distributions at a relatively stable level. The Fund uses derivatives as part of its strategy. The derivatives in which the Fund primarily invests are covered call options and FLEX Options. A derivative is a financial arrangement, the value of which is derived from, or based on, a traditional security, asset, or market index. The Fund sells covered calls with the aim of generating income and reducing volatility. When the Fund sells (writes) a call option, the Fund receives a premium but forfeits the opportunity to benefit from any appreciation of the underlying security above the option’s strike price. The Fund uses covered call options that are typically written (sold) as 30 days options, 5-10% out of the money on the positions, on up to 100% of an underlying position. The extent to which the Fund uses covered calls will depend on market conditions and PGI's ongoing assessment of the attractiveness of writing call options on the Fund's holdings. The Fund may hold cash or cash equivalents, including U.S. Treasury bills or other short‑term instruments, for collateral and operational purposes, including to meet obligations arising from its option writing strategy.

Strategy Narrative [Text Block]	The Fund is an actively managed exchange-traded fund (“ETF”) that seeks to achieve its investment objective by investing, under normal circumstances, at least 80% of its net assets, plus any borrowings for investment purposes, in emerging markets securities. The Fund invests in fixed-income securities, including those issued by sovereign, quasi-sovereign, and corporate issuers. The Fund also invests in fixed-income securities, including convertible bonds, credit- and index-linked securities, non-registered and restricted securities (including those issued in reliance on Rule 144A and Regulation S), securities issued by distressed or bankrupt issuers, and securities issued by the U.S government or U.S. government-sponsored enterprises. Emerging markets are generally defined to include all countries except Australia, Austria, Belgium, Canada, Denmark, Finland, France, Germany, Ireland, Italy, Japan, Netherlands, New Zealand, Norway, Portugal, Spain, Sweden, Switzerland, United Kingdom, and the United States. The Fund considers a security to be tied economically to an emerging market if one or more of the following criteria is present: (i) the issuer or guarantor of the security has its principal place of business or principal office in an emerging market; (ii) the principal trading market for the security is in an emerging market; (iv) the issuer or guarantor of the security derives a majority of its revenue from emerging markets; or (iv) the currency of settlement of the security is the currency of an emerging market. Emerging markets include frontier markets. The Fund invests, without limitation, in high yield securities (also known as “junk”) rated at the time of purchase Ba1 or lower by Moody’s Ratings, and BB+ or lower by S&P Global Ratings (“S&P Global”). If the security has been rated by only one of the rating agencies, that rating will determine the security’s rating; if the security is rated differently by the rating agencies, the highest rating will be used; and if the security has not been rated by either of the rating agencies, those selecting such investments will determine the security’s quality. The Fund’s holdings range in maturity from overnight to 30 years or more and are not subject to any minimum credit rating standard. The Fund’s investment process focuses primarily on market level analysis of global markets and political developments and their impact on individual countries and companies in emerging markets. The Fund uses a top-down portfolio construction process, blending both fundamental and technical considerations. The investment strategy provides considerable flexibility to invest in various asset classes, capital structures, maturities, and currencies. The Fund uses derivatives to enhance return and to hedge and manage investment risks. A derivative is a financial arrangement, the value of which is derived from, or based on, a traditional security, asset, or market index. Specifically, the Fund uses currency contracts, forward contracts, futures, options, and swaps. The Fund invests in cash and cash equivalents to support certain of these investments, as well as for other purposes.
