BRLN actively manages a broad portfolio of floating rate loans, effectively providing income that adjusts with prevailing interest rates. The fund typically invests in senior secured floating rate loans, second lien floating rate loans, and other subordinated or unsecured floating rate loans or debt. To a lesser extent, the fund may also hold fixed-rate loans whose interest payments are effectively converted into floating rate interest payments through the use of derivative instruments. Securities selected may be of any credit quality, including high yield, and may include loans or debt of foreign issuers without limitation. Up to 10% of the funds assets may be allocated to common stocks or other equities. The fund adviser has full discretion in managing the portfolio and may utilize derivatives such as options, futures, swaps, and forwards for hedging and non-hedging purposes. Prior to October 10, 2024, the fund used Blackrock for branding purposes.
