Investment limits govern mutual fund issuer exposure and inter-scheme transfers, with delivery rules and regulated derivatives access. Mutual fund schemes face issuer concentration limits for debt and equity with exemptions for government securities; debt investments must meet minimum credit ratings and board approval is required for certain extensions. Transfers between schemes must be at prevailing market spot prices and match the receiving scheme's objective. Aggregate inter-scheme investments are capped subject to fund-of-funds exceptions. Fund-of-funds schemes may invest only in mutual fund schemes except for disclosed liquidity needs. Purchases and sales require delivery except where regulated short selling, securities lending and exchange-traded derivatives apply; pending deployment, funds may be placed in short-term bank deposits under board guidelines.
