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 Example, affect the fund’s performance. During the most recent fiscal year, the fund’s portfolio turnover rate was 41% of the average value of its portfolio.
Principal Investment Strategy
Under normal market conditions, the fund invests at least 80% of its net assets in securitized bond investments. Securitized bond investments are also referred to as “structured product securities” or “structured products.” Securitized bond investments include secured loans backed by commercial real estate, residential real estate, commercial or consumer loans, and securitizations such as agency and non-agency mortgage-backed securities (MBS) (including commercial mortgage-backed securities (CMBS), residential mortgage-backed securities (RMBS), and collateralized mortgage obligations (CMOs)), asset-backed securities (ABS), and other similar securities and related instruments.
Agency MBS are issued or guaranteed by the US government, its agencies or instrumentalities, which include mortgage pass-through securities representing interests in pools of mortgage loans issued or guaranteed by the Government National Mortgage Association (GNMA or “Ginnie Mae”), the Federal National Mortgage Association (FNMA or “Fannie Mae”), the Student Loan Marketing Association (SLMA or “Sallie Mae”) or the Federal Home Loan Mortgage Corporation (FHLMC or “Freddie Mac”). The fund may also invest in other fixed income instruments, which include bonds, debt or credit securities and other similar instruments issued by various US and non-US public or private sector entities at the discretion of the Diamond Hill Capital Management, Inc. (the “Adviser”).
Under normal circumstances, the fund will maintain an average portfolio duration of less than three, although under certain market conditions, such as periods of significant volatility in interest rates and spreads, the fund’s average duration may be longer than three. Duration is an approximate measure of a bond's price sensitivity to changes in interest rates. For instance, a duration of “three” means that a security’s or portfolio’s price would be expected to decrease by approximately 3% with a 1% increase in interest rates (assuming a parallel shift in yield curve). The fund may invest in individual fixed income securities with effective durations in excess of three, provided, however, such investments are made within the constraints above.
The fund may invest up to 15% of its assets in below investment grade securities, including those referred to as “junk bonds” (or the unrated equivalent) at the time of purchase.

Short Duration Securitized Bond Fund SummaryFebruary 28, 2023

In selecting securities for the fund, the Adviser performs a risk/reward analysis that includes an evaluation of credit risk, interest rate risk, prepayment risk, and the legal and technical structure of the security. The Adviser will attempt to take advantage of inefficiencies that it believes exist in the fixed income markets. The Adviser seeks to invest in securities that the Adviser expects to offer attractive prospects for income and/or capital appreciation in relation to the risk borne.
Main Risks
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.
Asset-Backed, Mortgage-Related and Mortgage-Backed Securities Risk The fund may invest in asset-backed, mortgage-related and mortgage-backed securities, including so-called “sub-prime” mortgages that are subject to certain other risks including prepayment and call risks. When mortgages and other obligations are prepaid and when securities are called, the fund may have to reinvest in securities with a lower yield or fail to recover additional amounts (i.e., premiums) paid for securities with higher interest rates, resulting in an unexpected capital loss and/or a decrease in the amount of dividends and yield. In periods of rising interest rates, the fund may be subject to extension risk, and may receive principal later than expected. As a result, in periods of rising interest rates, the fund may exhibit additional volatility. During periods of difficult or frozen credit markets, significant changes in interest rates, or deteriorating economic conditions, such securities may decline in value, face valuation difficulties, become more volatile and/or become illiquid.
Collateralized mortgage obligations (“CMOs”) and stripped mortgage-backed securities, including those structured as interest only (“IOs”) and principal only (“POs”), are more volatile and may be more sensitive to the rate of prepayments than other mortgage-related securities. CMOs are issued in multiple classes, and each class may have its own interest rate and/or final payment date. A class with an earlier final payment date may have certain preferences in receiving principal payments or earning interest. As a result, the value of some classes in which the fund invests may be more volatile and may be subject to higher risk of non-payment. The risk of default, as described under “Credit Risk”, for “sub-prime” mortgages is generally higher than other types of mortgage-backed securities. The structure of some of these securities may be complex and there may be less available information than other types of debt securities.
The values of IO and PO mortgage-backed securities are more volatile than other types of mortgage-related securities. They are very sensitive not only to changes in interest rates, but also to the rate of prepayments. A rapid or unexpected increase in prepayments can significantly depress the price of interest-only securities, while a rapid or unexpected decrease could have the same effect on principal-only securities. In addition, because there may be a drop in trading volume, an inability to find a ready buyer, or the imposition of legal restrictions on the resale of securities, these instruments may
be illiquid. The fund will be exposed to additional risk to the extent that it uses inverse floaters and inverse IOs, which are debt securities with interest rates that reset in the opposite direction from the market rate to which the security is indexed. These securities are more volatile and more sensitive to interest rate changes than other types of debt securities. If interest rates move in a manner not anticipated by the Adviser, the fund could lose all or substantially all of its investment in inverse IOs.
Consumer Loans Risk Investments in consumer loans expose the fund to additional risks beyond those normally associated with more traditional debt instruments. The fund’s ability to receive payments in connection with the loan depends primarily on the financial condition of the borrower and whether or not a loan is secured by collateral, although there is no assurance that the collateral securing a loan will be sufficient to satisfy the loan obligation. In addition, bank loans often have contractual restrictions on resale, which can delay the sale and adversely impact the sale price. Transactions involving bank loans may have significantly longer settlement periods than more traditional investments (settlement can take longer than 7 days) and often involve borrowers whose financial condition is troubled or highly leveraged, which increases the risk that the fund may not receive its proceeds in a timely manner or that the fund may incur losses in order to pay redemption proceeds to its shareholders. In addition, loans are not registered under the federal securities laws like stocks and bonds, so investors in loans have less protection against improper practices than investors in registered securities.
Credit Risk  There is a risk that issuers and counterparties will not make payments on securities and repurchase agreements held by a fund. Such default could result in losses to the fund. In addition, the credit quality of securities held by the fund may be lowered if an issuer’s financial condition changes. Lower credit quality may lead to greater volatility in the price of a security and in shares of the fund. Lower credit quality also may affect liquidity and make it difficult for the fund to sell the security.
Fixed Income Risk  The fund invests in fixed income securities. These securities will increase or decrease in value based on changes in interest rates. If rates increase, the value of the fund’s fixed income securities generally declines. On the other hand, if rates fall, the value of the fixed income securities generally increases. Your investment will decline in value if the value of the fund’s investments decreases.
Government Securities Risk The fund may invest in securities issued or guaranteed by the U.S. government or its agencies and instrumentalities. These securities may be backed by the credit of the government as a whole or only by the issuing agency. U.S. Treasury bonds, notes, and bills and some agency securities, such as those issued by the Federal Housing Administration and Ginnie Mae, are backed by the full faith and credit of the U.S. government as to payment of principal and interest and are the highest quality government securities. Other securities issued by U.S. government agencies or instrumentalities, such as securities issued by the Federal Home Loan Banks and Freddie Mac, are supported only by the credit of the agency that issued them, and not by the U.S. government. Securities issued by the Federal Farm Credit System, the Federal Land Banks, and Fannie Mae are supported by the agency’s right to borrow money from the U.S. Treasury under certain circumstances, but are not

Short Duration Securitized Bond Fund SummaryFebruary 28, 2023

backed by the full faith and credit of the U.S. government. No assurance can be given that the U.S. government would provide financial support to its agencies and instrumentalities if not required to do so by law.
High Yield Securities Risk  The fund will purchase fixed income securities rated below the investment grade category. Securities in this rating category are speculative. Changes in economic conditions or other circumstances may have a greater effect on the ability of issuers of these securities to make principal and interest payments than they do on issuers of higher grade securities.
Inflation Risk  Because inflation reduces the purchasing power of income produced by existing fixed income securities, the prices at which fixed income securities trade will be reduced to compensate for the fact that the income they produce is worth less. This potential decrease in market value would be the measure of the inflation risk incurred by the fund.
LIBOR Transition Risk Instruments in which the fund invests may pay interest at floating rates based on the London Interbank Offered Rate (“LIBOR”) or may be subject to interest caps or floors based on LIBOR. The United Kingdom’s Financial Conduct Authority and LIBOR's administrator, ICE Benchmark Administration (the "IBA"), have ceased publishing most LIBOR settings and announced that a majority of U.S. dollar LIBOR settings will no longer be published after June 30, 2023. Various financial industry groups have been planning for the transition away from LIBOR, but there are challenges to converting certain securities and transactions to a new reference rate (e.g., the Secured Overnight Financing Rate (“SOFR”), which is intended to replace the U.S. dollar LIBOR). The nature of any replacement rate and the impact of the transition from LIBOR on the Fund, issuers of instruments in which the Fund invests, and the financial markets generally are unknown at this time and may adversely affect a fund’s performance.
Liquidity Risk The fund may not be able to purchase or sell a security in a timely manner or at desired prices or achieve its desired weighting in a security. Liquidity risk may result from the lack of an active market or a reduced number and capacity of traditional market participants to make a market in fixed income securities, and may be magnified during times of market stress. The fund may not be able to meet the requests to redeem fund shares without significant dilution of remaining investors' interest in the fund.
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 investments will perform as anticipated.
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.
Non-U.S. and Emerging Markets Risk The fund may invest in non-U.S. securities and U.S. securities of companies domiciled in non-U.S. countries that may experience more rapid and extreme changes in value than a fund that invests exclusively in securities of U.S. companies. These companies may be subject to additional risks, including political and economic risks, civil conflicts and war, greater volatility, expropriation and nationalization risks, currency fluctuations, higher transaction costs, delayed settlement, possible non-U.S. controls on investments, and less stringent investor protection and disclosure standards of non-U.S. markets. The departure of one or more other countries from the European Union may have significant political and financial consequences for global markets. These risks are magnified in emerging markets as events and evolving conditions in certain economies or markets may alter the risks associated with investments tied to countries or regions that historically were perceived as comparatively stable becoming riskier and more volatile. The market for the securities of issuers in emerging markets is typically small and low, and nonexistent trading volumes in those securities may result in a lack of liquidity and price volatility.
Prepayment and Call Risk The issuer of certain securities may repay principal in advance, especially when yields fall. Changes in the rate at which prepayments occur can affect the return on investment of these securities. When debt obligations are prepaid or when securities are called, the fund may have to reinvest in securities with a lower yield. The fund also may fail to recover additional amounts (i.e., premiums) paid for securities with higher coupons, resulting in an unexpected capital loss.
Performance
The following bar chart and table show two aspects of the fund: volatility and performance. The bar chart shows the volatility — or variability — of the fund’s annual total returns over time, and shows that fund performance can change from year to year. The table shows the fund’s average annual total returns for certain time periods compared to the returns of a broad-based securities index. The bar chart and table provide some indication of the risks of investing in the fund. Of course, the fund’s past performance is not necessarily an indication of its future performance.
