Diamond Hill Small Cap Fund Summary			As of February 28, 2023

Market Risk The value of the fund's investments may decrease, sometimes rapidly or unexpectedly, due to factors affecting an issuer held by the fund, particular industries or overall securities markets. When the value of the fund’s investments goes down, your investment in the fund decreases in value. A variety of factors including interest rate levels, recessions, inflation, U.S. economic growth, war or acts of terrorism, natural disasters, political events, supply chain disruptions, staff shortages and widespread public health issues affect the securities markets. These events may cause volatility, severe market dislocations and liquidity constraints in many markets, including markets for the securities the fund holds, and may adversely affect the fund's investments and operations. In addition, governmental responses to these events may negatively impact the capabilities of the fund's service providers, disrupt the fund's operations, result in substantial market volatility and adversely impact the prices and liquidity of the fund's investments.

Small Cap Company Risk  Investments in small cap companies may be riskier than investments in larger, more established companies. The securities of smaller companies may trade less frequently and in smaller volumes than securities of larger companies. In addition, smaller companies may be more vulnerable to economic, market and industry changes. As a result, share price changes may be more sudden or erratic than the prices of other equity securities, especially over the short term. Because smaller companies may have limited product lines, markets or financial resources or may depend on a few key employees, they may be more susceptible to particular economic events or competitive factors than large capitalization companies.

Sector Emphasis Risk The fund, from time to time, may invest 25% or more of its assets in one or more sectors, subjecting the fund to sector emphasis risk.

The fund, under normal market conditions, invests its assets in U.S. equity securities of any size capitalization that Diamond Hill Capital Management, Inc.

Equity securities consist of common and preferred stocks.

The Adviser focuses on estimating a company’s value independent of its current stock price. To estimate a company’s value, the Adviser concentrates on the fundamental economic drivers of the business. The primary focus is on “bottom-up” analysis, which takes into consideration earnings, revenue growth, operating margins and other economic factors.

The fund also will sell securities short. Short sales are effected when it is believed that the price of a particular security will decline, and involves the sale of a security which the fund does not own in hopes of purchasing the same security at a later date at a lower price. To make delivery to the buyer, the fund must borrow the security, and the fund is obligated to return the security to the lender, which is accomplished by a later purchase of the security by the fund. The frequency of short sales will vary substantially in different periods, and it is not intended that any specified portion of the fund’s assets will as a matter of practice be invested in short sales. The fund will not make a short sale if, immediately before the transaction, the market value of all securities sold short exceeds 40% of the value of the fund’s net assets.

All investments carry a certain amount of risk and the fund cannot guarantee that it will achieve its investment objective. An investment in the fund is not a deposit or obligation of any bank, is not endorsed or guaranteed by any bank, and is not insured by the Federal Deposit Insurance Corporation (FDIC) or any other government agency. You may lose money by investing in the fund. Below are the main risks of investing in the fund. All of the risks listed below are significant to the fund, regardless of the order in which they appear.

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 companies will perform as anticipated. The value of an individual company can be more volatile than the market as a whole, and the Adviser’s intrinsic value-oriented approach may fail to produce the intended results. In addition, there is no guarantee that the use of long and short positions will succeed in limiting the fund’s exposure to stock market movements, sector-swings or other risk factors. The strategy used by the fund involves complex securities transactions that involve risks different than direct equity investments.

Market Risk  The value of the fund's investments may decrease, sometimes rapidly or unexpectedly, due to factors affecting an issuer held by the fund, particular industries or overall securities markets. When the value of the fund’s investments goes down, your investment in the fund decreases in value. A variety of factors including interest rate levels, recessions, inflation, U.S. economic growth, war or acts of terrorism, natural disasters, political events, supply chain disruptions, staff shortages and widespread public health issues affect the securities markets. These events may cause volatility, severe market dislocations and liquidity constraints in many markets, including markets for the securities the fund holds, and may adversely affect the fund's investments and operations. In addition, governmental responses to these events may negatively impact the capabilities of the fund's service providers, disrupt the fund's operations, result in substantial market volatility and adversely impact the prices and liquidity of the fund's investments.

Short Sale Risk  The fund will incur a loss as a result of a short sale if the price of the security sold short increases in value between the date of the short sale and the date on which the fund purchases the security to replace the borrowed security. In addition, a lender may request, or market conditions may dictate, that securities sold short be returned to the lender on short notice, and the fund may have to buy the securities sold short at an unfavorable price. If this occurs, any anticipated gain to the fund may be reduced or eliminated or the short sale may result in a loss. The fund’s losses are potentially unlimited in a short sale transaction. Short sales are speculative transactions and involve special risks, including greater reliance on the Adviser’s ability to accurately anticipate the future value of a security.

Small Cap and Mid Cap Company Risk  Investments in small cap and mid cap companies may be riskier than investments in larger, more established companies. The securities of these companies may trade less frequently and in smaller volumes than securities of larger companies. In addition, small cap and mid cap companies may be more vulnerable to economic, market and industry changes.
