Unitisation is the process of converting a pool of assets—such as a portfolio of securities, property, or loans—into standardised, tradeable units of equal value, enabling fractional ownership and easier investor participation. In the mutual fund industry, unitisation underpins the entire structure: a fund's total assets are divided into units, each representing a proportional share of the portfolio. In the context of group insurance or pension funds, unitisation allows individual policyholder contributions to be tracked as units in an underlying investment fund. Unitisation improves transparency, enables daily pricing, and allows seamless entry and exit for investors.
