The First Trust Senior Loan Fund is an actively managed exchange-traded fund (ETF) that primarily aims to deliver substantial current income. This is achieved by principally allocating its capital to a diverse portfolio of first-priority, senior, floating-rate bank loans, commonly referred to as "Senior Loans." A secondary goal of the fund is the protection of its invested capital. Under normal market conditions, the fund commits at least 80% of its net assets to Senior Loans, with a focus on those extended to businesses predominantly operating in North America.
