The Western Asset Short Duration Income ETF (WINC) typically allocates a minimum of 80% of its total assets, including any capital acquired through borrowing for investment, to high-quality debt instruments. A significant component of these holdings consists of corporate debt, which encompasses various financial tools like notes, bonds, debentures, and commercial paper. Businesses commonly issue these types of fixed-income securities to fund their operational activities. Such debt instruments can be either backed by collateral (secured) or not (unsecured), may be issued by entities located in the U.S. or abroad, and often bear interest rates that are variable or adjustable.
