First Trust High Income Long/Short Fund (the "Fund") is a diversified, closed-end management investment company. The Fund's primary investment objective is to provide current income. The Fund's secondary objective is capital appreciation. The Fund seeks to achieve its investment objectives by investing, under normal market conditions, a majority of its assets in a diversified portfolio of U.S. and foreign (including emerging markets) high-yield corporate fixed-income securities of varying maturities that are rated below-investment grade at the time of purchase. For purposes of this strategy, "corporate fixed-income securities" include corporate bonds, debentures, notes, commercial paper and other similar types of corporate debt instruments, including instruments issued by corporations with direct or indirect government ownership, as well as asset-backed securities, preferred shares, senior floating-rate loan participations, commitments and assignments, payment-in-kind securities, zero-coupon bonds, bank certificates of deposit, fixed time deposits, bankers' acceptances and derivative instruments that provide the same or similar economic impact as a physical investment in the above securities. Below-investment grade fixed-income securities are commonly referred to as "high-yield" or "junk" bonds and are considered speculative with respect to the issuer's capacity to pay interest and repay principal. As part of its investment strategy, the Fund intends to maintain both long and short positions in securities under normal market conditions. The Fund will take long positions in securities that the Fund's Sub-Advisor believes offer the potential for attractive returns and that it considers in the aggregate to have the potential to outperform the Fund's benchmark, the ICE BofA US High Yield Constrained Index (the "Index"). The Fund will take short positions in securities that the Sub-Advisor believes in the aggregate will underperform the Index. The Fund's long positions, either directly or through derivatives, may total up to 130% of the Fund's Managed Assets. The Fund's short positions, either directly or through derivatives, may total up to 30% of the Fund's Managed Assets. "Managed Assets" means the average daily gross asset value of the Fund (which includes the principal amount of any borrowings), minus the sum of the Fund's liabilities.
