Open-endedness
ICVCs are open-ended; the fund is equitably divided into shares which vary in price in direct proportion to the variation in value of the fund's net asset value. Each time money is invested new shares are created to match the prevailing share price; each time shares are redeemed the assets sold match the prevailing share price. In this way there is no supply or demand created for shares and they remain a direct reflection of the underlying assets. ICVCs may be single-priced (there is one price at which shares may be bought or sold) or dual-priced, in which case there will be a buying price and a selling price, with the difference between the two being the bid–offer spread.
There is a great resource covering the taxation of Oeics which can be found on Adviser Index - Taxation of OEICs
