The First Trust Senior Loan Fund is an actively managed exchange-traded fund. The fund's primary investment objective is to provide high current income by investing primarily in a diversified portfolio of first lien senior floating-rate bank loans ("Senior Loans"). The fund's secondary investment objective is the preservation of capital. Under normal market conditions, the fund will invest in at least 80% of its net assets in Senior Loans that are made predominantly to businesses operating in North America and may also invest up to 20% of its net assets in non-Senior Loan debt securities, warrants, equity securities and securities of other investment companies.
