These Regulations amend the Individual Savings Account Regulations 1998 (S.I. 1998/1870: “the main Regulations”). They correct a technical drafting defect in the Individual Savings Account Regulations (Amendment No. 2) Regulations 2004 (S.I. 2004/2996). Those Regulations applied the “5% test,” used to identify if investments are cash-like in form, in a modified form to investments held in an ISA insurance component on 6th April 2005, to determine whether those investments will be held in a stocks and shares component or cash component from that date.
