Unit trust

A unit trust is a form of collective investment constituted under a trust deed. Trusts are found in Fiji, Ireland, the Isle of Man, Guernsey, Jersey, New Zealand, Australia, Kenya, Namibia, South Africa, Singapore, Malaysia and the UK. Unit trusts offer access to a wide range of securities.

Unit trusts are open-ended investments; meaning that unlike investment trusts there is not a finite number of units in issue, and these can increase or decrease dependent upon the net sales and repurchase by existing unit holders. These units are managed within what is known as the "Managers Box". The Box Manager of the fund will make a decision at each valuation point whether or not to Create (add) or to Liquidate (Remove) units based on the final net sales and redemptions prior to the next valuation point where the Fund is priced on a "Forward Basis", or at the actual valuation point where the fund is priced on an Historic basis. Forward pricing is the most common.

The underlying value of the assets is always directly represented by the total number of units issued multiplied by the unit price less the transaction or management fee charged and any other associated costs. Each fund has a specified investment objective to determine the management aims and limitations.

Unit trusts are open-ended; the fund is equitably divided into units 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 units are created to match the prevailing unit buying price; each time units are redeemed the assets sold match the prevailing unit selling price. In this way there is no supply or demand created for units and they remain a direct reflection of the underlying assets. Unit trust trades do not have any commission.

The fund manager makes a profit in the difference between the purchase price of the unit or offer price and the sale value of units or the bid price. This difference is known as the bid–offer spread. The bid–offer spread will vary depending on the type of assets held and can be anything from a few basis points on very liquid assets like UK/US government bonds, to 5% or more on assets that are harder to buy and sell such as property. The trust deed often gives the manager the right to vary the bid–offer spread to reflect market conditions, with the purpose of allowing the manager to control liquidity. In some jurisdictions the bid–offer spread is referred to as the "bid–ask spread".
