The Fund may invest in sponsored or unsponsored depositary receipts.●The Fund may establish short positions in stocks of foreign companies with a market value of up to 10% of the Fund’s assets. When the Fund takes a short position, it sells at the current market price a stock it has borrowed in anticipation of a decline in the market price of the stock. The Fund intends to reinvest the proceeds from its short sales by taking additional long positions in stocks. This investment technique is known as “leverage,” which increases risk and may magnify the Fund’s gains or losses.●The Fund may use futures, options, swaps and forwards to gain exposure to foreign markets and currencies. Sub-Advisers may make currency investment decisions independent of their underlying security selections. The Fund may also use derivatives, including futures, options, forward contracts and swap agreements as a substitute for investing directly in an underlying asset, to increase return, to manage risk, to hedge against losses or as an alternative to selling a security short.●The Fund may invest its uninvested cash in high-quality, short-term debt securities, which may include repurchase agreements and high-quality money market instruments, and also may invest uninvested cash in the GuideStone Funds Money Market Fund. To the extent the Fund invests in a money market fund, it generally is not subject to the limits placed on investments in other investment companies. Generally, these securities offer less potential for gains than other types of securities.●The Fund uses a multi-manager approach, using two or more Sub-Advisers that each manages a portion of the Fund's portfolio under the oversight of the Adviser. The Sub-Advisers, in managing their respective portions of the Fund’s portfolio, practice different investment styles that the Adviser believes complement one another. The Adviser recommends sub-adviser selections to the Board of Directors of GuideStone Funds and determines allocations of Fund assets among Sub-Advisers based on a variety of qualitative and quantitative factors in an attempt to maximize return across the entire portfolio while minimizing risk to the extent possible. Buy and sell decisions are made at the discretion of each individual Sub-Adviser with regard to the portion of the Fund’s portfolio that it manages in accordance with its investment strategies and processes.●In accordance with GuideStone Financial Resources of the Southern Baptist Convention's (GuideStone®) Christian values, the Fund does not invest in any company that is publicly recognized (as determined by GuideStone) for offering products or services that are incompatible with the Christian values of GuideStone, including, but not limited to, those involving abortion, sexual immorality, alcohol, tobacco or gambling.
