The Columbia Research Enhanced International Equity ETF (REFA) dedicates a minimum of 80% of its total assets, including any capital acquired through borrowing, to investments in equity securities. These holdings comprise a variety of instruments, such as ordinary shares traded on local exchanges, American Depositary Receipts (ADRs), and Global Depositary Receipts (GDRs), all issued by companies based in developed international economies. The fund's underlying index is derived from a specific, narrower selection of companies chosen from a broader initial investment universe.
