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 Adviser evaluates ESG metrics when selecting certain securities, the Fund’s portfolio may perform differently than funds that do not use ESG metrics. ESG metrics 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 securities identified by the Adviser to fit within its sustainability criteria do not operate as anticipated. Although the Adviser seeks to identify issuers that fit within its 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 Adviser’s 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.

Waste-related Risks. Companies operating in the waste water value chain can be affected by, among other things, availability and cost of labor to collect and transport waste, transportation costs, consumer and industry trends and subsequent waste volumes, regulatory changes on collection, and treatment of waste. These companies can also be affected by overall economic trends, government spending on related projects, and the cost of commodities.

Small‑Cap and Mid‑Cap Company Risk. The small- and mid‑capitalization companies in which the Fund invests in may be more vulnerable to adverse business or economic events than larger, more established companies. In particular, these small- and mid‑capitalization companies may have limited product lines, markets, and financial resources, and may depend upon relatively small management groups. Therefore, small- and mid‑capitalization stocks may be more volatile than those of larger companies.

Derivatives Risk. The Fund may use derivatives (including futures and forward contracts) to hedge against market declines. The Fund’s use of derivative instruments involves risks different from, or possibly greater than, the risks associated with investing directly in securities and other traditional investments. These risks include (i) the risk that the counterparty to a derivative transaction may not fulfill its contractual obligations; (ii) risk of mispricing or improper valuation; and (iii) the risk that changes in the value of the derivative may not correlate perfectly with the underlying asset, rate or index.

Emerging Markets Risk. In addition to the risks of investing in non‑U.S. investments generally, emerging markets investments are subject to greater risks including or arising from political or economic instability, nationalization or confiscatory taxation, capital controls, currency exchange restrictions, sanctions by other countries (such as the United States) and an issuer’s unwillingness or inability to make principal or interest payments on its obligations. Emerging markets companies may be smaller and have shorter operating histories than companies in developed markets. Emerging market investments are also subject to enhanced custody risk, a risk that is inherent in the process of clearing and settling trades and to the holding of securities, cash and other assets by local banks, agents and depositories. Low trading volumes and volatile prices in less developed markets make trades harder to complete and settle, and governments or trade groups may compel local agents to hold securities in designated depositories that may not be subject to independent evaluation. Communications between the U.S. and emerging market countries may be unreliable, increasing the risk of delayed settlements or losses of security certificates. Practices in relation to the settlement of securities transactions in emerging markets involve higher risks than those in developed markets. In addition, the laws of certain countries may put limits on a Fund’s ability to recover its assets if a foreign bank or depository or issuer of a security or an agent of any of the foregoing goes bankrupt. A Fund would absorb any loss resulting from such custody problems and may have no successful claim for compensation. To the extent a Fund invests in frontier countries, these risks will be magnified. Frontier countries generally have smaller economies or less developed capital markets than traditional emerging market countries.

IPO Risk. The Fund may purchase securities in Initial Public Offerings (“IPOs”). These securities are subject to many of the same risks of investing in companies with smaller market capitalizations. Securities issued in IPOs have no trading history, and information about the companies may be available for very limited periods. In addition, the prices of securities sold in IPOs may be highly volatile.

Liquidity Risk. The Fund may make investments that are illiquid or that may become less liquid in response to market developments or adverse investor perceptions. Illiquid investments may be more difficult to value.

Active Management Risk. The Adviser’s judgments about the attractiveness, value and potential appreciation of a particular asset class or individual security in which the Fund invests may prove to be incorrect, and there is no guarantee that individual securities will perform as anticipated. Any given investment strategy may fail to produce the intended results, and the Fund’s portfolio may underperform other comparable funds because of portfolio management decisions related to, among other things, the selection of investments, portfolio construction, evaluation of an issuer’s corporate governance practices, risk assessments, and/or the outlook on market trends and opportunities.

Regulatory Risk. Changes in the laws or regulations of the United States or other countries, including any changes to applicable tax laws and regulations, could impair the ability of the Fund to achieve its investment objective and could increase the operating expenses of the Fund.

Equity Securities Risk. The risk that events negatively affecting issuers, industries or financial markets in which the Fund invests will impact the value of the stocks held by the Fund and thus, the value of the Fund’s shares over short or extended periods.
