LDUR actively invests in a global portfolio of primarily investment-grade debt, relying on PIMCO's research and security selection capability. It's the longer-duration and less picky sibling of MINT. Unlike MINT, which has a mandate for ultra-short-duration and USD-denominated, investment-grade-only exposure, LDUR has longer target duration and can also hold high-yield securities (B or better), non-USD-denominated debt, and emerging debt.
