To pursue its goal, the fund generally invests in stocks that are included in the RAFI Fundamental High Liquidity Developed ex US Small Index†. 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 developed ex 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 developed ex U.S. companies within the parent universe. The index is comprised of the smallest developed ex U.S. companies by fundamental size. The bottom 12.5% of the companies by cumulative fundamental score are included in the index. The companies included in the index, and their respective weights, 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 fund’s 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, including depositary receipts representing securities of the index; which may be in the form of American Depositary Receipts (ADRs), Global Depositary Receipts (GDRs) and European Depositary Receipts (EDRs). The fund will notify its shareholders at least 60 days before changing this policy. 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. The fund does not hedge its exposure to foreign currencies. However, the fund may use forward contracts to lock in exchange rates for the portfolio securities purchased or sold, but awaiting settlement. These transactions establish a rate of exchange that can be expected to be received upon settlement of the securities.

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 as necessary to reflect various corporate actions (such as mergers and spin-offs), (b) other investment companies, and (c) derivatives, principally futures contracts. The fund may use futures contracts and other derivatives primarily to seek returns on the fund’s 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.

Because it may not be possible or practicable to purchase all of the stocks in the index, the investment adviser seeks to track the total return of the index by using sampling techniques. Sampling techniques involve investing in a limited number of index securities which, when taken together, are expected to perform similarly to the index as a whole. These techniques are based on a variety of factors, including performance attributes, tax considerations, capitalization, dividend yield, price/earnings ratio, industry factors, risk factors and other characteristics. The fund generally expects that its portfolio will hold less than the total number of securities in the index, but reserves the right to hold as many securities as it believes necessary to achieve the fund’s investment objective. The fund generally expects that its portfolio characteristics will be similar to those of the 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.
