Invesco RAFI Developed Markets ex-U.S. Small-Mid ETF (PDN) is an exchange-traded fund that seeks to track the performance of the RAFI Fundamental Select Developed ex-US 1500 Index, focusing on small- and mid-capitalization equities in developed international markets excluding the United States; the fund generally invests at least 90% of its total assets in securities comprising the index, including American depositary receipts and global depositary receipts; securities are selected and weighted based on four fundamental measures of firm size—book value, cash flow, sales, and dividends—with the index reconstituted annually and computed on a net return basis that withholds taxes for non-resident investors. Launched on September 27, 2007, PDN exhibits sector allocations led by industrials (23.32%), financials (12.55%), and consumer discretionary (11.82%), with top country exposures in Japan (31.05%), Canada (9.03%), and South Korea (8.10%); top holdings as of September 19, 2025, include Doosan Co Ltd (0.28%), Hanwha Aerospace Co Ltd (0.28%), and Sumitomo Pharma Co Ltd (0.24%), among approximately 1,800-1,855 total holdings spanning mid- and small-cap value, blend, and growth styles. The fund, managed by Invesco Ltd.—a global investment management firm founded in 1935 and headquartered at 1331 Spring Street NW, Suite 2500, Atlanta, Georgia—targets institutional and retail investors seeking exposure to fundamentally weighted developed ex-U.S. small-mid equities, with operations supporting products available on U.S. exchanges and distributed worldwide through Invesco's network in over 20 countries. Effective close of business on March 21, 2025, PDN underwent significant updates, including a change in its underlying index from the FTSE RAFI Developed ex U.S. Mid-Small 1500 Index to the RAFI Fundamental Select Developed ex-US 1500 Index, a name change to Invesco RAFI Developed Markets ex-U.S. Small-Mid ETF, and a reduction in its management fee to 47 basis points. These enhancements align with Invesco Ltd.'s broader strategic focus on refining ETF offerings amid ongoing global expansion efforts, such as recent partnerships including a November 2025 asset management collaboration with Zopa Bank in the UK and an accelerated Iberian purpose-built student accommodation joint venture with Amro launched in October 2024.
