The index selects, ranks, and weights securities by fundamental measures of company size adjusted sales, retained operating cash flow, and dividends plus buybacks rather than market capitalization. The index measures the performance of the small company size segment by fundamental overall company scores (scores), which are created using as the universe the U.S. companies in the RAFI Global Equity Investable Universe (the parent universe). Securities are grouped in order of decreasing score and each company receives a weight based on its percentage of the total scores of the U.S. companies within the parent universe. The index is comprised of the smallest U.S. companies by fundamental size. The bottom 12.5% of the companies by cumulative fundamental score are included in the index. The companies, and their respective weights, included in the index are determined annually and are implemented using a partial quarterly reconstitution methodology in which the index is split into four equal segments and each segment is rebalanced on a rolling quarterly basis. The method of calculating the components of the index is subject to change. It is the funds policy that, under normal circumstances, it will invest at least 90% of its net assets (including, for this purpose, any borrowings for investment purposes) in stocks included in the index. The fund will notify its shareholders at least 60 days before changing this policy. The fund will generally seek to replicate the performance of the index by giving the same weight to a given stock as the index does. However, when the investment adviser believes it is in the best interest of the fund, such as to avoid purchasing odd-lots (i.e., purchasing less than the usual number of shares traded for a security), for tax considerations, or to address liquidity considerations with respect to a stock, the investment adviser may cause the funds weighting of a stock to be more or less than the indexs weighting of the stock. The fund may sell securities that are represented in the index in anticipation of their removal from the index, or buy securities that are not yet represented in the index in anticipation of their addition to the index. Under normal circumstances, the fund may invest up to 10% of its net assets in securities not included in the index. The principal types of these investments include, but are not limited to, those that the investment adviser believes will help the fund track the index, such as investments in (a) securities that are not represented in the index but the investment adviser anticipates will be added to the index or Index ownership The RAFI Fundamental High Liquidity US Small Index (the Index) is a service mark of RAFI Indices, LLC or its affiliates (collectively, RAFI) and has been licensed for use by Charles Schwab Investment Management, Inc.

The fund may use futures contracts and other derivatives primarily to seek returns on the funds otherwise uninvested cash assets to help it better track the index. The fund may also invest in cash and cash equivalents, including money market funds, and may lend its securities to minimize the difference in performance that naturally exists between an index fund and its corresponding index. The fund will concentrate its investments (i.e., hold more than 25% of its total assets) in a particular industry, group of industries or sector to approximately the same extent that the index is so concentrated.
