rr_StrategyNarrativeTextBlock

Under normal circumstances, the Fund invests at least 65% of its net assets in equity securities of foreign issuers, including non-U.S. dollar denominated securities and securities of emerging market issuers. The Fund will normally invest at least 80% of its assets in investments that meet the sustainability criteria of the Fund’s sub-advisers, Schroder Investment Management North America Inc. (“SIMNA”) and Schroder Investment Management North America Limited (“SIMNA Ltd.,” together with SIMNA, the “Sub-Advisers”). The Fund seeks to be diversified across sectors, style, market capitalization and growth drivers. The Fund may invest in securities of any market capitalization, but tends to focus on large and medium capitalization companies. The equity securities in which the Fund may invest include, but are not limited to, common stock and preferred stock. The Fund may use derivatives, such as options and futures contracts, in order to gain exposure to particular securities or markets, in connection with hedging transactions, equitizing cash, or otherwise to seek to increase total return.The Sub-Advisers use fundamental analysis to evaluate a security for purchase or sale by the Fund. For purposes of determining the Fund’s investment universe, the Sub-Advisers include securities that they believe have been mispriced by the market as well as securities that they believe can generate capital growth. The Sub-Advisers then apply their sustainability criteria to create the Fund’s portfolio. In implementing the investment strategy, the Sub-Advisers seek to maintain a higher overall sustainability score for the Fund than that of the Fund’s benchmark, the MSCI ACWI ex USA Index (Net), as measured through the Sub-Adviser’s proprietary sustainable scoring methodology. The Sub-Advisers also generally seek to manage the Fund so that the aggregate, absolute carbon footprint of the corporate issuers held within the Fund at the portfolio level is lower than the aggregate, absolute carbon footprint of the corporate issuers of the Fund’s benchmark index.For purposes of determining which investments meet the Sub-Advisers’ sustainability criteria, each company considered for inclusion will be assessed and monitored using a quantitative framework that includes environmental, social and governance (“ESG”) measures. This quantitative framework includes an assessment of sustainability scores as compared against the benchmark index, sector-specific subsets of the benchmark index and/or regional equivalents of the benchmark index. The Sub-Advisers will use their internally developed sustainability scores to identify companies that, in their view, demonstrate sound or improving sustainability practices. As part of this process, the Sub-Advisers will consider selecting from companies that (1) have an attractive sustainability score based on the Sub-Advisers’ proprietary rating system, (2) demonstrate improvement to address ESG issues and/or (3) engage with the Sub-Advisers concerning the improvement of the companies’ ESG issues. The Sub-Advisers’ sustainability scores evaluate the impact and risk around issues such as climate change, environmental performance, labor standards or corporate governance, which are considered in the assessment of investments. This assessment is supported by both quantitative analysis from the Sub-Advisers’ proprietary sustainability tools and qualitative analysis from the Sub-Advisers’ analysts, which award a sustainability score to each company. Environmental and social measures include, but are not limited to, the strength of environmental practices, climate change impact, responsible employment practices, and sensitivity towards the communities in which the companies operate. Governance measures include signals that seek to quantify the extent to which management teams act in the best interest of the principals or shareholders of the firm.The Fund does not generally invest in companies that are significantly involved in certain industries, product lines or services, including but not limited to, tobacco, thermal coal, alcohol, gambling, adult entertainment, nuclear power and oil and gas, as determined from time to time by the Sub-Advisers, unless the Sub-Advisers view the issuer as one which contributes to or is aligning itself with long-term ESG initiatives. In determining whether a company is significantly involved in the industries, product lines or services listed above, the Sub-Advisers typically use revenue thresholds attributable to certain industries, product lines or services (e.g., companies that derive 5% or more of their revenues from conventional oil and gas extraction) and categorical exclusions for other industries, product lines or services (e.g., controversial weapons). These exclusionary criteria may be updated periodically by the Sub-Advisers without notice to shareholders to, among other things, add or remove certain industries, product lines or services from the screening process, revise the revenue thresholds and categorical exclusions applicable to such activities, or change particular industries, product lines or services from a categorical exclusion to a revenue threshold, or vice versa.The Fund may invest among a number of different sectors and countries throughout the world with no limit on the amount of assets that may be invested in any one sector or country. Based on market or economic conditions, the Fund may, through its normal bottom-up stock selection process, focus in one or more sectors of the market. The Fund will consider an issuer to be located in a country if it is organized under the laws of that country and is principally traded in that country, or is domiciled and has its principal place of business located in that country and is principally traded in that country, or if the Sub-Advisers determine that the issuer has more than 50% of its assets in, or derives more than 50% of its revenues from, that country.

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

The principal risks of investing in the Fund are described below. When you sell your shares they may be worth more or less than what you paid for them, which means that you could lose money as a result of your investment. An investment in the Fund is not a bank deposit and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. As with any fund, there is no guarantee that the Fund will achieve its investment objective.Market Risk – Market risk is the risk that one or more markets in which the Fund invests will go down in value, including the possibility that the markets will go down sharply and unpredictably. Securities of a company may decline in value due to its financial prospects and activities, including certain operational impacts, such as data breaches and cybersecurity attacks. Securities may also decline in value due to general market and economic movements and trends, including adverse changes to credit markets, or as a result of other events such as geopolitical events, natural disasters, or widespread pandemics (such as COVID-19) or other adverse public health developments.Foreign Investments Risk – Investments in foreign securities may be riskier, more volatile, and less liquid than investments in U.S. securities. Differences between the U.S. and foreign regulatory regimes and securities markets, including the less stringent investor protection, less stringent accounting, corporate governance, financial reporting and disclosure standards of some foreign markets, as well as political and economic developments in foreign countries and regions and the U.S. (including the imposition of sanctions, tariffs, or other governmental restrictions), may affect the value of the Fund’s investments in foreign securities. Changes in currency exchange rates may also adversely affect the Fund’s foreign investments. The impact of the United Kingdom’s departure from the European Union, commonly known as “Brexit,” and the potential departure of one or more other countries from the European Union may have significant political and financial consequences for global markets. This may adversely impact Fund performance.Emerging Markets Risk – The risks related to investing in foreign securities are generally greater with respect to investments in companies that conduct their principal business activities in emerging markets or whose securities are traded principally on exchanges in emerging markets. The risks of investing in emerging markets include risks of illiquidity, increased price volatility, smaller market capitalizations, less government regulation and oversight, less extensive and less frequent accounting, financial, auditing and other reporting requirements, significant delays in settlement of trades, risk of loss resulting from problems in share registration and custody and substantial economic and political disruptions. In addition, the imposition of exchange controls (including repatriation restrictions), sanctions, confiscations, trade restrictions (including tariffs) and other government restrictions by the United States and other governments may also result in losses. Frontier markets are those emerging markets that are considered to be among the smallest, least mature and least liquid, and as a result, the risks of investing in emerging markets are magnified in frontier markets.Currency Risk – The risk that the value of the Fund’s investments in foreign securities or currencies will be affected by the value of the applicable currency relative to the U.S. dollar. When the Fund sells a foreign currency or foreign currency denominated security, its value may be worth less in U.S. dollars even if the investment increases in value in its local market. U.S. dollar-denominated securities of foreign issuers may also be affected by currency risk, as the revenue earned by issuers of these securities may also be affected by changes in the issuer’s local currency.Regional/Country Focus Risk – To the extent that the Fund focuses its investments in a particular geographic region or country, the Fund may be subject to increased currency, political, regulatory, economic and other risks associated with that region or country. A natural or other disaster could occur in a geographic region in which the Fund invests, which could affect the economy or particular business operations of companies in the specific geographic region. As a result, the Fund may be subject to greater price volatility and risk of loss than a fund holding more geographically diverse investments.Equity Risk – The risk that the price of equity or equity related securities may decline due to changes in a company’s financial condition and overall market and economic conditions.Large Cap Securities Risk – The securities of large market capitalization companies may underperform other segments of the market because such companies may be less responsive to competitive challenges and opportunities and may be unable to attain high growth rates during periods of economic expansion.Mid-Cap Securities Risk – The securities of mid-capitalization companies generally trade in lower volumes and are generally subject to greater and less predictable price changes than the securities of larger capitalization companies.Active Investment Management Risk – The risk that, if the the Sub-Advisers’ investment strategy does not perform as expected, the Fund could underperform its peers or lose money.Sustainable Investing Risk – Applying sustainability criteria to the investment process may exclude or reduce exposure to securities of certain issuers for sustainability reasons and, therefore, the Fund may forgo some market opportunities available to funds that do not use sustainability criteria. The Fund’s performance may at times be better or worse than the performance of funds that do not use sustainability criteria. Because the Sub-Advisers evaluate ESG characteristics when selecting certain securities, the Fund’s portfolio may perform differently than funds that do not use ESG characteristics. A focus on ESG characteristics may prioritize long term rather than short term returns. ESG information and data, including that provided by third parties, may be incomplete, inaccurate, or unavailable, which could adversely affect the analysis relevant to a particular investment. In addition, there is a risk that the investments identified by the Sub-Advisers to fit within their sustainability criteria do not operate as anticipated. Although the Sub-Advisers seek to identify issuers that fit within their sustainability criteria, investors may differ in their views of what fits within this category of investments. As a result, the Fund may invest in issuers that do not reflect the beliefs and values of any particular investor. The Sub-Advisers’ exclusion of certain investments from the Fund’s investment universe may adversely affect the Fund’s relative performance at times when such investments are performing well.Liquidity Risk – The risk that the market for a particular investment or type of investment is or becomes relatively illiquid, making it difficult for the Fund to sell that investment at an advantageous time or price. Illiquidity may be due to events relating to the issuer of the securities, market events, rising interest rates, economic conditions or investor perceptions. Illiquid securities may be difficult to value and their value may be lower than the market price of comparable liquid securities, which would negatively affect the Fund’s performance.Sector Risk – To the extent the Fund invests more heavily in a particular sector or sectors, its performance will be especially sensitive to developments that significantly affect those sectors. Individual sectors may be more volatile, and may perform differently, from the broader market.Derivatives Risk – Derivatives are instruments whose value depends on, or is derived from, the value of an underlying asset, reference rate or index. Derivatives may be riskier than other types of investments because they may be more sensitive to changes in economic or market conditions than other types of investments and could result in losses that significantly exceed the Fund’s original investment. Successful use of derivative instruments by the Fund depends on the Sub-Advisers’ judgment with respect to a number of factors and the Fund’s performance could be worse and/or more volatile than if it had not used these instruments. In addition, the fluctuations in the value of derivatives may not correlate perfectly with the value of any portfolio assets being hedged, the performance of the asset class to which the Sub-Advisers seek exposure, or the overall securities markets.Futures and Options Risk – Futures and options may be more volatile than direct investments in the securities underlying the futures and options, may not correlate perfectly to the underlying securities, may involve additional costs, and may be illiquid. Futures and options also may involve the use of leverage as the Fund may make a small initial investment relative to the risk assumed, which could result in losses greater than if futures or options had not been used. Futures and options are also subject to the risk that the other party to the transaction may default on its obligation.Counterparty Risk – The risk that the counterparty in a transaction by the Fund may be unable or unwilling to make timely principal, interest or settlement payments, or otherwise to honor its obligations.New Fund Risk – The Fund is a new fund which may result in additional risk. There can be no assurance that the Fund will grow to an economically viable size, in which case the Fund may cease operations. In such an event, investors may be required to liquidate or transfer their investments at an inopportune time.Large Shareholder Transaction Risk – The Fund may experience adverse effects when certain large shareholders redeem or purchase large amounts of shares of the Fund. Such redemptions may cause the Fund to sell securities at times when it would not otherwise do so or borrow money (at a cost to the Fund), which may negatively impact the Fund’s performance and liquidity. Similarly, large purchases may adversely affect the Fund’s performance to the extent that the Fund is delayed in investing new cash and is required to maintain a larger cash position than it ordinarily would. These transactions may also accelerate the realization of taxable income to shareholders if such sales of investments resulted in gains, and may also increase transaction costs.Securities Lending Risk – The Fund may lose money because the borrower of the loaned securities fails to return the securities in a timely manner or at all. The Fund could also lose money in the event of a decline in the value of the collateral provided for loaned securities or a decline in the value of any investments made with cash collateral. These events could also trigger adverse tax consequences for the Fund.The Fund is subject to certain other risks. For more information regarding risks and investments, please see “Additional Information Regarding Investment Strategies and Risks” and “More Information About Risks” in the Fund’s statutory prospectus.
