Example

The following examples are intended to help you compare the cost of investing in the Fund with the cost of investing in other funds. The examples assume that you invest $10,000 in the Fund for the time periods indicated and then redeem all of your shares at the end of those periods, that your investment has a 5% return each year and that the Fund's operating expenses remain the same. Although your actual costs may be higher or lower, based on these assumptions your costs would be: 

	1 Year	3 Years	5 Years	10 Years
Class A	$646	$901	$1,175	$1,957
Class B	$699	$915	$1,257	$2,285
Class C	$311	$652	$1,119	$2,410

You would pay the following expenses if you did not redeem your shares: 

	1 Year	3 Years	5 Years	10 Years
Class B	$199	$615	$1,057	$2,285
Class C	$211	$652	$1,119	$2,410

Portfolio Turnover

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the examples, affect the Fund's performance. During the most recent fiscal year, the Fund's portfolio turnover rate was 92.29% of the average value of its portfolio.

Principal Investment Strategy

The Fund is sub-advised by Redwood Investments, LLC ("Redwood"), an affiliate of the Manager (Redwood and the Manager, collectively referred to as the "Manager," where applicable). Subject to the general supervision by the Fund's Board of Trustees, the Manager oversees Redwood and evaluates its performance results. The Manager reviews portfolio performance, compliance with investment guidelines and federal securities laws, and changes in key personnel of Redwood. Redwood is primarily responsible for the day-to-day management of the Fund's portfolio, including purchases and sales of individual securities.

The Fund invests in companies that it believes meet three primary criteria: (1) high quality companies, (2) which are attractively valued, and (3) where the Manager believes that future earnings and free cash flow growth will be meaningfully above what is expected by the market. High quality companies are those companies that offer strong earnings visibility and sustainability because of their durable competitive advantages, capable management teams, and prudent financial management. The Manager focuses on understanding industry and company dynamics to assess company quality, and on identifying and forecasting critical drivers to reach a differentiated view of future growth.

The Fund is an all-cap, all-country, opportunistic focus fund which generally holds less than 50 holdings. Fund holdings may differ from this number for a variety of reasons, including, among others, because of extreme market volatility, such as when the Fund has entered a temporary defensive position. Additionally, the Fund may exceed the stated number of holdings when it acquires a new holding and determines that it is in the best interests of shareholders to sell an existing holding over a period of time, instead of immediately selling the entire holding.

Under normal circumstances, the Fund invests at least 80% of its net assets in equity securities, including common stocks, American Depositary Receipts and Global Depositary Receipts, of foreign companies. Foreign companies, which are generally defined by a third party, but may be defined by the Portfolio Manager, are companies that (i) that are organized under the laws of a foreign country; (ii) whose securities are primarily listed in a foreign country; or (iii) that have a majority of their assets, or derive more than 50% of their revenue or profits from businesses, investments, or sales, outside the United States. The Fund normally focuses its foreign investments in developed countries, but may also invest in emerging market securities. The Fund may invest in companies of any market capitalization, from large, well-established companies to small, emerging growth companies.

Emerging market countries include all countries categorized as Emerging Markets or Frontier Markets by Morgan Stanley Capital International (MSCI).

The Fund generally invests in at least three foreign countries, and, at times, may invest a substantial portion of its assets in a single foreign country.

The Fund may sell a stock when it reaches a target price, it fails to perform as expected, or other opportunities appear more attractive. As a result, the Fund may engage in active trading of portfolio securities.

The Fund may invest a significant portion of its assets in securities of companies conducting business within a single sector, as defined by third party sources, including, but not limited to, the information technology, communication services, industrials and financials sectors. For the purpose of categorizing companies, sectors are a broader category than industries and industries comprise sectors.

The Fund may invest in cash (and cash equivalents) when the Fund is unable to find enough attractive long-term investments to meet its investment objective, to meet redemptions and/or when the Manager believes it is advisable to do so during times of short-term market volatility. During these times, cash (and cash equivalents) will not exceed 15% of the Fund's net assets.

The Fund's investment objective is a fundamental policy and may not be changed without shareholder approval.

Principal Risks

An investment in the Fund involves risks. The Fund's share price may go down, which means you could lose money. An investment in the Fund is not a deposit of a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. The following is a summary description of principal risks involved in investing in the Fund.

Investment Risk - An investment in the Fund is subject to investment risk, including the possible loss of the entire principal amount that you invest.

Market Risk - Your investment in Fund shares represents an indirect investment in the securities owned by the Fund. The value of these securities, like other investments, may move up or down, sometimes rapidly and unpredictably. Your Fund shares at any point in time may be worth less than what you invested, even after taking into account the reinvestment of Fund dividends and distributions. Local, regional or global events such as environmental or natural disasters, war, terrorism, pandemics, outbreaks of infectious diseases, and similar public health threats, trade disputes and changes in trade regulations, civil unrest, recessions, or other events could have a significant impact on the Fund and its investments.

Equity Securities Risk - As with any fund that invests in stocks, your investment will fluctuate in value, and the loss of your investment is a risk of investing. The Fund's price per share will fluctuate due to changes in the market prices of its investments. Also, the Fund's investments may not grow as fast as the rate of inflation and stocks tend to be more volatile than some other investments you could make, such as bonds.

Foreign Securities Risk - The Fund's performance will be influenced by political, social and economic factors affecting investments in foreign companies. Special risks associated with investments in foreign companies include exposure to currency fluctuations, lack of liquidity, potential for market manipulation, less developed or less efficient trading markets, limited access to reliable capital, lack of comprehensive company information, political instability, differing audit, regulatory, and legal standards and lack of financial reporting standards. Additionally, events and evolving conditions in certain markets or regions may alter the risk profile of investments tied to those markets or regions. This may cause investments tied to such markets or regions to become riskier or more volatile, even when investments in such markets or regions were perceived as comparatively stable historically. In addition, foreign companies with securities listed on U.S. exchanges may be delisted if they do not meet U.S. accounting standards and auditor oversight requirements, which may decrease the liquidity and value of the securities.

Emerging Markets Risk - The Fund may invest in issuers located in emerging markets, and therefore may be exposed to the economies, industries, securities and currency markets of such countries, which may be adversely affected by protectionist trade policies, a slow U.S. economy, political and social instability, regional and global conflicts, terrorism and war, including actions that are contrary to the interests of the United States. Emerging markets are riskier than more developed markets because they tend to develop unevenly and may never fully develop. Investments in emerging markets may be considered speculative. Emerging markets are more likely to experience hyperinflation and currency devaluations, which adversely affect returns to U.S. investors. In addition, many emerging securities markets have far lower trading volumes and less liquidity than developed markets. The Fund, individually or in combination with other shareholders, may have limited rights and remedies against emerging market issuers.

Frontier Markets Risk - The Fund may invest in issuers located in frontier countries. Frontier markets are those emerging markets that are considered to be among the smallest, least mature and least liquid, and as a result, may be more likely to experience inflation, political turmoil and rapid changes in economic conditions than more developed and traditional emerging markets. Investments in frontier markets may be subject to a greater risk of loss than investments in more developed and traditional emerging markets. Frontier markets often have less uniformity in accounting, auditing and financial reporting requirements, unreliable securities valuations and greater risk associated with custody of securities. Economic, political and currency risks may be more pronounced with respect to investments in frontier markets than in emerging markets.

Small Number of Holdings Risk - Under normal circumstances, the Fund invests in a small number of issuers. Therefore, the Fund's performance may be more vulnerable to changes in the market value of a single issuer and more susceptible to risks associated with a single economic, political, or regulatory occurrence than a fund that has a higher number of holdings.

Sector Risk - The Fund may have a significant portion of its assets invested in securities of companies conducting business within a single sector, as defined by third party sources. Companies in the same sector may be similarly affected by economic, regulatory, political or market events or conditions, which may make the Fund more vulnerable to unfavorable developments in that sector than a fund that has a more diversified portfolio. Generally, the more broadly the Fund invests, the more it spreads risk and potentially reduces the risks of loss and volatility.

communication services sector may also be affected by other competitive pressures, such as pricing competition, as well as research and development costs, substantial capital requirements and government regulation. Additionally, fluctuating domestic and international demand, shifting demographics and often unpredictable changes in consumer tastes can drastically affect a communication services company's profitability. While all companies may be susceptible to network security breaches, certain companies in the communication services sector may be particular targets of hacking and potential theft of proprietary or consumer information or disruptions in service, which could have a material adverse effect on their businesses.

Growth Securities Risk - Prices of growth stocks tend to be higher in relation to their companies' earnings and may be more sensitive to market, political and economic developments than other stocks, making their prices more volatile. An investment in the Fund may be better suited to investors who seek long-term capital growth and can tolerate fluctuations in their investment's value.

Small Cap Securities Risk - There may be greater risk in investing in companies with small market capitalizations rather than larger, more established companies owing to such factors as more limited product lines or financial resources or lack of management depth. It may also be difficult or impossible to liquidate a security position at a time and price acceptable to the Fund because of the potentially less frequent trading of stocks of smaller market capitalization.

Cash Position Risk - At times, the Fund may hold up to 15% of its net assets in cash (and cash equivalents), which may underperform relative to equity securities.

Performance

The following bar chart and the table beneath it provide some indication of the risks of investing in the Fund by showing changes in the Fund's performance from year to year. The bar chart shows how the Fund's average annual returns have varied over the indicated periods. The table shows how the Fund's average annual returns compare with those of an appropriate broad-based securities market index that represents the overall international equity market. Performance in the bar chart does not reflect the effect of the sales charge imposed on purchases of Class A Shares of the Fund. If the bar chart reflected the applicable sales charges, returns would be less than those shown. Before February 1, 2024, the Fund was managed by different portfolio managers and before August 6, 2024, the Fund was named "Alger International Focus Fund." Before March 28, 2018, the Fund followed different investment strategies and was managed by different portfolio managers and before August 15, 2018, the Fund was named "Alger International Growth Fund." Performance prior to February 1, 2024 reflects these prior management styles and does not reflect the Fund's current investment personnel and performance prior to March 28, 2018 does not reflect the Fund's current investment strategies. The Fund's past performance (before and after taxes) is not necessarily an indication of how it will perform in the future. Updated performance information is available on the Fund's website www.alger.com.

In the foregoing table, after-tax returns are calculated using the historical highest individual federal marginal income tax rates and do not reflect the impact of state and local taxes. Actual after-tax returns depend on an investor's tax situation and may differ from those shown. The after-tax returns shown may not be relevant to investors who hold their Fund shares through tax-deferred arrangements, such as 401(k) plans or individual retirement accounts. A "Return After Taxes on Distributions and Sale of Fund Shares" may sometimes be higher than the other two return figures; this happens when there is a capital loss on redemptions, giving rise to a tax benefit to the shareholder. After-tax returns for Class B and C Shares, which are not shown, will vary from those shown for Class A Shares.
