Category I AIF investment conditions restrict eligible investments, limit leverage, and impose disclosure and lock in obligations for SME investments. Category I Alternative Investment Funds must invest in prescribed investee entities and specified units of other AIFs, may undertake hedging subject to Board conditions, and are prohibited from borrowing or using leverage except for short-term temporary funding and operational needs under tightly limited conditions; encumbrances on equity of infrastructure investees are permitted for those investee borrowings under Board-specified conditions. Subcategories (venture capital, SME, social impact, infrastructure) must meet targeted investable-fund allocations, have specified exemptions for SME due-diligence trading with disclosure and one-year lock-in, and may engage in permitted subscription or market-making arrangements.
