Fees and Expenses of the Fund

This table describes the fees and expenses that you may pay if you buy and hold shares of the Long/Short Fund.

Redemption Fee (as a percentage of amount redeemed on shares held 60 days or less)			1.00	%			1.00	%
ANNUAL FUND OPERATING EXPENSES(expenses that you pay each year as a percentage of the value of your investment)
Management Fees			1.50	%			1.50	%
Distribution and Service (Rule 12b-1) Fees			0.25	%			None
Other Expenses (includes Shareholder Servicing Plan Fee and Interest Expense and Dividends on Securities Sold Short)			2.13	%			2.03	%
Shareholder Servicing Plan Fee	0.10	%			None
Interest Expense and Dividends on Securities Sold Short	0.95	%			0.95	%

⁽¹⁾ Pzena Investment Management, LLC (the “Adviser”) has contractually agreed to waive a portion or all of its management fees and pay Long/Short Fund expenses to ensure that Total Annual Fund Operating Expenses (excluding acquired fund fees and expenses ("AFFE"), interest expense, taxes, dividends on securities sold short and extraordinary expenses) do not exceed 2.10% of average daily net assets of the Investor

1

Class shares and 1.75% of average daily net assets of the Institutional Class shares (the “Expense Caps”). The Expense Caps will remain in effect through at least June 27, 2020, and may be terminated only by the Trust’s Board of Trustees (the “Board”). The Adviser may request recoupment of previously waived fees and paid expenses from the Fund for 36 months from the date they were waived and paid, subject to the Expense Caps.

Example. This Example is intended to help you compare the cost of investing in the Long/Short Fund with the cost of investing in other mutual funds. The Example assumes 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. The Example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses remain the same (taking into account the Expense Caps only in the first year).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
Investor Class	$308	$1,108	$1,926	$4,053
Institutional Class	$273	$1,006	$1,761	$3,746

Portfolio Turnover. The Long/Short 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 example, affect the Fund’s performance. The Adviser expects that the Fund’s active or frequent trading of portfolio securities will result in a portfolio turnover rate in excess of 100% on an annual basis. During the most recent fiscal year, the Fund’s portfolio turnover rate was 58% of the average value of its portfolio.

Principal Investment Strategies

Under normal market conditions, the Long/Short Fund seeks to achieve long-term capital appreciation through long positions in securities priced below, and short positions in securities priced above, the Adviser’s estimate of long-term earnings power. The Fund invests primarily in publicly traded equity securities. The Long/Short Fund makes long and short investments in a diversified portfolio of primarily common stocks. The Fund invests in stocks following a research-driven, bottom-up and quantitative security selection process. The Fund’s long positions are stocks that, in the opinion of the Adviser, sell at a substantial discount to their intrinsic value but have solid long-term prospects. The short portfolio will be a broadly diversified basket of stocks that the Adviser believes to be expensive relative to their earnings history. On average, the Fund is 110% long and 60% short, for a net long position of 50%.

In managing the Fund’s assets, the Adviser will follow a classic value strategy. The Fund primarily invests in U.S. listed companies among the largest 1,000 ranked companies by market capitalization, but may invest up to 20% of its net assets in shares of foreign companies through American Depository Receipts (“ADRs”) or dollar-denominated foreign securities. The Fund’s investments in foreign securities may include investments in emerging market securities. The Fund may also invest in real estate investment trusts (“REITs”). From time to time, the Fund may invest, to a significant extent, in securities of companies in the same economic sector. As of February 28, 2019, 24.18% of the Fund's total investments were invested in the financial services sector.

In evaluating an investment for purchase by the Long/Short Fund, the Adviser focuses on the company’s earnings history, underlying financial condition and business prospects considering estimated earnings, economic conditions, degree of competitive or pricing pressures, the potential impacts of material environmental, social and governance (ESG) factors, and the experience and competence of management, among other factors. The Adviser’s sell discipline is guided by the same process with which the Adviser originally screens the investment universe. The Adviser typically sells a security when it reaches fair value, there are more attractive opportunities or there is a change in company fundamentals.

The Long/Short Fund expects to engage in frequent trading of the Fund’s portfolio securities.

Principal Risks

2

Losing all or a portion of your investment is a risk of investing in the Long/Short Fund. The following additional risks could affect the value of your investment:

• Market and Regulatory Risk. Events in the financial markets and economy may cause volatility and uncertainty and adversely impact the Fund’s performance. Market events may affect a single issuer, industry, sector, or the market as a whole. Traditionally liquid investments may experience periods of diminished liquidity. Governmental and regulatory actions, including tax law changes, may also impair portfolio management and have unexpected or adverse consequences on particular markets, strategies, or investments.

• Management Risk. The Long/Short Fund is an actively managed investment portfolio and the Fund relies on the Adviser’s ability to pursue the Fund’s goal. The Adviser will apply its investment techniques and risk analyses in making investment decisions for the Fund, but there can be no guarantee that its decisions will produce the desired results.

• Equity Securities Risk. The price of equity securities may rise or fall because of economic or political changes or changes in a company’s financial condition, sometimes rapidly or unpredictably. These price movements may result from factors affecting individual companies, sectors or industries selected for the Fund’s portfolio or the securities market as a whole, such as changes in economic or political conditions.

• Foreign Securities Risk. Foreign securities are subject to special risks in addition to those of U.S. issuers. Foreign securities can be more volatile than domestic (U.S.) securities. Securities markets of other countries are generally smaller than U.S. securities markets. Many foreign securities may be less liquid and more volatile than U.S. securities, which could affect the Long/Short Fund’s investments.

• Emerging Markets Risk. In addition to the risks of foreign securities in general, investments in emerging markets may be riskier than investments in or exposure to investments in the U.S. and other developed markets for many reasons, including smaller market capitalizations, greater price volatility, less liquidity, a higher degree of political and economic instability (which can freeze, restrict or suspend transactions in those investments, including cash), the impact of economic sanctions, less governmental regulation and supervision of the financial industry and markets, and less stringent financial reporting and accounting standards and controls.

• Depositary Receipt Risk. Holders of unsponsored depositary receipts generally bear all the costs of such facilities and the depositary of an unsponsored facility frequently is under no obligation to distribute shareholder communications received from the issuer of the deposited security or to pass through voting rights to the holders of such receipts of the deposited securities.

• Currency Risk. Changes in foreign currency exchange rates will affect the value of what the Fund owns and the Fund’s share price. Generally, when the U.S. dollar rises in value against a foreign currency, an investment in that country loses value because that currency is worth fewer U.S. dollars. Devaluation of a currency by a country’s government or banking authority also will have a significant impact on the value of any investments denominated in that currency. Currency markets generally are not as regulated as securities markets and the risk may be higher in emerging markets.

• Sector Emphasis Risk. The securities of companies in the same or related businesses, if comprising a significant portion of the Long/Short Fund’s portfolio, could react in some circumstances negatively to market conditions, interest rates and economic, regulatory or financial developments and adversely affect the value of the portfolio to a greater extent than if such business comprised a lesser portion of the Fund’s portfolio.

◦ Financial Services Sector Risk. Financial services companies are subject to extensive governmental regulation which may limit both the amounts and types of loans and other financial commitments they can make, the interest rates and fees they can charge, the scope of their activities, the prices they can charge and the amount of capital they must maintain. Profitability is largely dependent on the availability and cost of capital funds, and can fluctuate significantly when interest rates change or due to increased competition. Certain events in the financial sector may cause an unusually high degree of volatility in the financial markets, both domestic and foreign, and cause certain financial services companies to incur large losses. Securities of financial services companies may experience a dramatic decline in value when such companies experience substantial declines in the valuations of their assets, take action to raise capital (such as the issuance of debt or equity securities), or cease operations. Credit losses resulting from financial difficulties of borrowers and financial losses associated with investment activities can negatively impact the sector.

3

• Liquidity Risk. Low or lack of trading volume may make it difficult to sell securities held by the Long/Short Fund at quoted market prices.

• Value Style Investing Risk. The Fund emphasizes a “value” style of investing, which targets undervalued companies with characteristics for improved valuations. This style of investing is subject to the risk that the valuations never improve or that the returns on “value” securities may not move in tandem with the returns on other styles of investing or the stock market in general.

• Short Sales Risk. A short sale is the sale by the Long/Short Fund of a security which it does not own in anticipation of purchasing the same security in the future at a lower price to close the short position. A short sale will be successful if the price of the shorted security decreases. However, if the underlying security goes up in price during the period in which the short position is outstanding, the Fund will realize a loss. The risk on a short sale is unlimited because the Fund must buy the shorted security at the higher price to complete the transaction. Therefore, short sales may be subject to greater risks than investments in long positions.

• Leverage Risk. Leverage is investment exposure which exceeds the initial amount invested. Selling securities short involves the use of leverage. Leverage can cause the Long/Short Fund’s portfolio to lose more than the principal amount invested. Leverage can magnify the portfolio’s gains and losses and therefore increase its volatility.

• Portfolio Turnover Risk. A high portfolio turnover rate (100% or more) has the potential to result in the realization and distribution to shareholders of higher capital gains, which may subject you to a higher tax liability.

• Real Estate Investment Trust (REIT) Risk. Investments in REITs are subject to the same risks as direct investments in real estate and mortgages which include, but are not limited to, sensitivity to changes in real estate values and property taxes, interest rate risk, tax and regulatory risk, fluctuations in rent schedules and operating expenses, adverse changes in local, regional or general economic conditions, deterioration of the real estate market and the financial circumstances of tenants and sellers, unfavorable changes in zoning, building, environmental and other laws, the need for unanticipated renovations, unexpected increases in the cost of energy and environmental factors. In addition, the underlying mortgage loans may be subject to the risks of default or of prepayments that occur earlier or later than expected, and such loans may also include so-called “sub-prime” mortgages. The value of REITs will also rise and fall in response to the management skill and creditworthiness of the issuer. In particular, the value of these securities may decline when interest rates rise and will also be affected by the real estate market and by the management of the underlying properties. REITs may be more volatile and/or more illiquid than other types of equity securities. The Fund will indirectly bear its proportionate share of expenses, including management fees, paid by each REIT in which it invests in addition to the expenses of the Fund.

The after-tax returns were 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, and after-tax returns are not relevant to investors who hold shares of the Long/Short Fund through tax-deferred arrangements, such as 401(k) plans or individual retirement accounts (“IRAs”). The Return After Taxes on Distributions and Sale of Fund Shares is higher than other return figures when a capital loss occurs upon redemption and provides an assumed tax deduction that benefits the investor.
