Only periods greater than 12 months are annualized. Fred Alger Management, Inc. (“FAM”) has contractually agreed to reimburse Fund expenses (excluding interest, taxes, brokerage, and extraordinary expenses) through Febru- ary 28, 2019 to the extent necessary to limit the total annual Fund operating expenses of the Class I to 1.20% of the class’ average daily net assets. FAM may, during the 1-year term of the expense reimbursement contract (“ERC”), recoup any expenses waived or reimbursed pursuant to the ERC to the extent that such recoupment would not cause the expense ratio to exceed the lesser of the stated limitation in effect at the time of (i) the waiver or reimbursement and (ii) the recoupment. This commitment may only be amended or terminated prior to its expiration date by agreement between FAM and the Fund’s Board of Trustees, and will terminate automatically in the event of termination of Investment Advisory Agreement. Prior to 8/07/15, the Fund followed different investment strategies under the name “Alger Growth Opportunities Fund” and prior to 2/12/15 was managed by a different port- folio manager. Accordingly, performance prior to those dates does not reflect the Fund’s current investment strategies and investment personnel. Effective 8/07/15, the Fund’s primary benchmark is the Russell 2000 Growth Index. The performance data quoted represents past performance, which is not an indication or a guarantee of future results. Investment return and principal value of an investment will fluctuate so that an investor’s shares, when redeemed, may be worth more or less than their original cost. Current performance may be lower or higher than the performance quoted. Performance figures assume all distributions are reinvested.

Risk Disclosures: Investing in the stock market involves gains and losses and may not be suitable for all investors. The value of an investment may move up or down, sometimes rapidly and unpredictably, and may be worth more or less than what you invested. Stocks tend to be more volatile than other investments such as bonds. Growth stocks tend to be more volatile than other stocks as the 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. Investing in companies of small capitalizations involve the risk that such issuers may have limited product lines or financial resources, lack management depth, or have more limited liquidity. The Fund may have a more concentrated portfolio than other funds, so it may be more vulnerable to changes in the market value of a single issuer and may be more susceptible to risks associated with a single economic, political or regulatory occurrence than a fund that has a more diversified portfolio. Since the Fund concentrates its investments in the health sciences sector, the value of the Fund’s shares may be more volatile than those that do not similarly concentrate their investments. Changes in applicable regulations could adversely affect companies in these industries, and the pace of product development and technological advancement in comparative companies may result in greater volatility of the price of securities of such companies. Many technology companies have limited operating histories and prices of these compa- nies’securities have historically been more volatile than other securities due to increased competition, government regulation, and risk of obsolescence due to the progress of technological developments. The Fund may have a significant portion of its assets invested in securities of healthcare companies, which may be significantly affected by intense competition, aggressive pricing, government regulation, technological innovations, product obsolescence, patent considerations, product compatibility and consumer preferences, and may be more volatile than the securities of other companies. The cost of borrowing money to leverage may exceed the returns for the securities purchased or the securities purchased may actually go down in value more quickly than if the Fund had not borrowed. Foreign investing involves special risks including currency risk and risks related to politi- cal, social, or economic conditions.

Morningstar percentile rankings are based on the total return percentile rank that includes reinvested dividends and capital gains (excluding sales charge) within each Morn- ingstar Category. The highest (or most favorable) percentile rank is 1 and the lowest (or least favorable) percentile rank is 100. If sales charges were included, performance would be lower and the rank may be lower. Rankings and ratings may be based in part on the performance of a predecessor fund or share class and are calculated by Morningstar using a performance calculation meth- odology that differs from that used by Fred Alger Management, Inc.’s. Differences in the methodologies may lead to variances in calculating total performance returns, in some cases this variance may be significant, thereby potentially affecting the rating/ranking of the Fund(s). When an expense waiver is in effect, it may have a material effect on the total return or yield, and therefore the rating/ranking for the period.
