IHYF operates as an actively managed fund, employing a systematic, factor-based investment strategy. Its primary objective is to identify fixed-income securities that the Sub-adviser believes offer superior risk-adjusted returns compared to other bonds, based on quantifiable issuer characteristics. This approach typically leads to a higher allocation towards bonds exhibiting strong value, low volatility, or high carry potential. The portfolio managers have the flexibility to adapt, introduce, or modify these underlying factors as they deem appropriate to mitigate specific investment risks. In addition to core bond holdings, the fund may also allocate to various other instruments, within specified limits, including U.S. Treasuries, collateralized debt obligations (CDOs), and distressed bonds. It's important to note that market movements can cause the fund's asset allocation to deviate from its intended limits. A significant aspect of the strategy is its emphasis on derivatives, such as options, futures, forward contracts, swaps, and certain mortgage-backed and asset-backed securities. This extensive use of derivatives is primarily for hedging purposes, aiming to protect the portfolio against key investment risks like interest rate fluctuations and adverse foreign currency movements.
