The iBoxx EUR Liquid High Yield 2027 3-Year Rolling measures the performance of EUR-denominated, high yield corporate bonds with maturity dates between Oct. 1, 2026, and Sept. 30, 2027. At each rebalancing, issuer weights are capped at 3% during the first two years of the rolling period and are market value weighted in the final year. Throughout the final months of the maturity year of the index, bond proceeds are moved into an iBoxx EUR T-Bill Index. After the final year, rather than expiring, the iBoxx EUR Liquid High Yield 2027 3-Year Rolling rolls into another three-year maturity index, putting weight back into high yield bonds with a three-year fixed maturity, extending the index to Sept. 30, 2030. The index continues to roll in three-year increments.
