This Practice Note describes the genuine diversity of ownership (GDO) condition which authorised investment funds (AIFs) are required to satisfy in certain situations. First, AIFs which are qualified investor schemes (QIS) or long-term asset funds (LTAFs) for regulatory purposes must satisfy the GDO condition in order to access the AIF tax regime. Second, all AIFs must satisfy the GDO condition in order to benefit from the ‘investment transactions list’ (sometimes referred to as the ‘white list’) which can provide certainty that capital profits will not be recharacterised as trading profits taxable as income. Third, the GDO condition allow relevant AIFs to enter into the property AIF (PAIF) and tax elected fund (TEF) tax regimes. This Practice Note also looks at the GDO advance clearance procedure. This Practice Note is produced in partnership with Camilla Spielman of Eversheds Sutherland.
