Unit-based employee benefit schemes must meet lock-in, minimum vesting, disclosure and accounting requirements under InvIT regulations. Unit based employee benefit schemes require that units held by an employee benefit trust be used only to provide benefits, be locked by the depository and released solely for transfers to eligible employees, and not be sold otherwise. Schemes must observe a minimum vesting period, appropriate appropriation timelines for secondary-acquired unbacked units with committee-approved extensions, deployment of accumulated cash in unencumbered liquid assets, and specified disclosures and accounting compliance by the investment manager. On change of investment manager, the outgoing manager stops receiving fees or units and the outgoing trust must dispose of its units within a prescribed period.
