Example

This example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds.

The example assumes that you invest $1,000,000 in Class I Shares or $10,000 in Class A Shares or Class C Shares of the Fund for the time periods indicated and that you sell your shares at the end of those periods. The example also assumes that each year your investment has a 5% return and Fund operating expenses remain the same. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

Expense Example - Summit Global Investments Global Low Volatility Fund - USD ($)	One Year	Three Years	Five Years	Ten Years
Class I	8,575	37,094	67,751	154,828
Class A	630	950	1,292	2,256
Class C	187	678	1,197	2,619

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. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund's performance. Portfolio turnover may vary from year to year, as well as within a year. During the most recent fiscal year, the portfolio turnover rate of the Fund was 247% of the average value of its portfolio.

Principal Investment Strategies

The Fund invests, under normal market conditions, significantly (ordinarily at least 40% - unless market conditions are not deemed favorable by the Adviser, in which case the Fund would invest at least 30%) in non-U.S. companies. The Fund defines non-U.S. companies as companies that (i) are organized under the laws of a foreign country; (ii) whose principal trading market is in a foreign country; or (iii) that have a majority of their assets or derive a significant portion of their revenue or profits from businesses, investments or sales, outside of the United States.

The Fund's investments will generally consist of securities, which may include common stocks, preferred stocks, warrants to acquire common stock, and securities convertible into common stock. The Fund purchases equity securities traded in the U.S. on registered exchanges or the over-the-counter market. The Fund primarily utilizes American Depository Receipts (ADRs) for exposure to non-U.S. equities.

The Adviser attempts to lower the Fund's market risk by investing in equity securities that lower the overall volatility of the Fund's portfolio as compared to global equity benchmarks. Volatility is a statistical measurement of the magnitude of up and down fluctuations in the value of a financial instrument or index. The Fund invests in stocks that exhibit less volatile stock price patterns, strengthening business metrics (i.e., earnings, debt, return on assets, competition, customers, industry, etc.) and quantitative factors such as earnings variability, leverage, volatility, price/book, price/cash flow, etc. The Adviser selects securities for the Fund that it anticipates will produce less volatility with more capital protection and more consistent returns. While the Adviser attempts to manage the Fund's volatility, there is no guarantee that the strategy will be successful or that the Fund's portfolio will not experience periods of volatility.

The Fund may sell a stock if the Adviser identifies fundamental, governance or legal risks or if the risk/return ranking declines due to increasing risk and/or decreasing return potential. The Fund may also decrease weight in an investment for risk control purposes.

Principal Risks

Loss of money is a risk of investing in the Fund. In addition, your investment in the Fund may be subject to the following principal risks:

• Common Stock Risk. Investments in common stocks are subject to market, economic and business risks that will cause their price to fluctuate over time. Therefore, an investment in the Fund may be more suitable for long-term investors who can bear the risk of these fluctuations.

• Convertible Securities Risk. Securities that can be converted into common stock, such as certain securities and preferred stock, are subject to the usual risks associated with fixed income investments, such as interest rate risk and credit risk. In addition, because they react to changes in the value of the equity securities into which they will convert, convertible securities are also subject to the risks associated with equity securities.

• Foreign Securities Risk. International investing is subject to special risks, including, but not limited to, currency exchange rate volatility, political, social or economic instability, and differences in taxation, auditing and other financial practices.

• Low Volatility Risk. Although subject to the risks of common stocks, low volatility stocks are seen as having a lower risk profile than the overall markets. However, a portfolio comprised of low volatility stocks may not produce investment exposure that has lower variability to changes in such stocks' price levels. Investing in low volatility stocks may limit the Fund's gains in rising markets.

• Management Risk. The Fund is subject to the risk of poor stock selection. In other words, the individual stocks in the Fund may not perform as well as expected, and/or the Fund's portfolio management practices do not work to achieve their desired result.

• Market Risk. The net asset value ("NAV") of the Fund will change with changes in the market value of its portfolio positions. Investors may lose money. Although the Fund will invest in stocks the Adviser believes will produce less volatility, there is no guarantee that the stocks will perform as expected.

• Opportunity Risk. As with all mutual funds, the Fund is subject to the risk of missing out on an opportunity because the assets necessary to take advantage of it are tied up in less advantageous investments.

• Warrants Risk. The purchase of warrants involves the risk that the Fund could lose the purchase value of a warrant if the right to subscribe to additional shares is not executed prior to the warrant's expiration. Also, the purchase of warrants involves the risk that the effective price paid for the warrant added to the subscription price of the related security may exceed the value of the subscribed security's market price such as when there is no movement in the level of the underlying security.

Performance Information

Returns shown were generated under the management of the Fund’s former investment adviser and reflect a previous investment strategy. The Fund operated as a series of Scotia Institutional Funds prior to the close of business on March 21, 2014 (the "Predecessor Fund"). Before the Fund commenced operations, all of the assets and liabilities of the Predecessor Fund were transferred to the Fund in a tax-free reorganization (the "Reorganization"). The Reorganization occurred on March 21, 2014. As a result of the Reorganization, the Fund assumed the performance and accounting history of the Predecessor Fund prior to the date of the Reorganization. The performance shown for periods prior to March 21, 2014 is that of the Predecessor Fund. The bar chart and performance table below provide an indication of the risk of an investment in the Fund.

The Board approved the Adviser to serve as the Global Low Volatility Fund’s investment adviser effective January 1, 2017. Returns shown for periods prior to January 1, 2017 were generated under the management of the Global Low Volatility Fund’s former investment adviser.

The chart below illustrates the performance of the Fund’s Class I Shares. Performance for Class A Shares and Class C Shares is not shown because Class A Shares and Class C Shares had not commenced operations prior to the date of this Prospectus. The information shows you how the Fund's performance has varied year by year and provides some indication of the risks of investing in the Fund. The chart assumes reinvestment of dividends and distributions. As with all such investments, past performance (before and after taxes) is not an indication of future results. Performance reflects fee waivers in effect. If fee waivers were not in place, the Fund's performance would be reduced.

[1] A contingent deferred sales charge of 1.00% is assessed on certain redemptions of Class A Shares made within 18 months after purchase where no initial sales charge was paid at time of purchase as part of an investment of $1,000,000 or more.

[1] Prior to March 24, 2017, the management fee was 0.65%.

[2] The expense information has been restated to reflect current fees.

[3] Summit Global Investments, LLC (the "Adviser"), the Fund's investment adviser, has contractually agreed to waive fees and reimburse expenses to the extent that Total Annual Fund Operating Expenses (excluding taxes, extraordinary expenses, short sale dividend expenses, brokerage commissions and interest) exceed 0.84% for Class I Shares, 1.09% for Class A Shares and 1.84% for Class C Shares until March 31, 2019. Prior to such date, this contractual agreement may only be terminated by the Fund's Board of Directors. If it becomes unnecessary for the Adviser to waive fees or make reimbursements, the Adviser may recapture any of its prior waivers or reimbursements for a period not to exceed three years from the date on which the waiver or reimbursement was made to the extent that such a recapture does not cause the Total Annual Fund Operating Expenses (excluding taxes, extraordinary expenses, short sale dividend expenses, brokerage commissions and interest) to exceed the applicable expense limitation that was in effect at the time of the waiver or reimbursement.

[1] While the Predecessor Fund commenced operations on March 31, 2009, the Predecessor Fund began investing consistent with its investment objective on April 1, 2009.

[2] 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. After-tax returns shown are not relevant to investors who hold their Fund shares through tax-deferred arrangements, such as 401(k) plans or individual retirement accounts ("IRAs").

[3] Effective January 2017, the Fund discontinued the use of the Russell 1000® Growth Index and replaced it with the MSCI ACWI Index. The Fund believes that use of the MSCI ACWI Index provides a better comparative benchmark since it more appropriately reflects the securities in which the Fund may invest.
