The S&P U.S. High Yield Corporate Bond Index is designed to track the performance of U.S. dollar-denominated, high-yield corporate bonds issued by companies whose country of risk use official G-10 currencies, excluding those countries that are members of the United Nations Eastern European Group (EEG). Qualifying securities must have a below-investment-grade rating (based on the lowest of S&P Global Ratings, Moody’s, and Fitch) and maturities of one or more months.
