Cash at bank earns/pays interest at floating rates based on daily deposit bank rates. Short-term deposits, which include bank and money market deposits, are made for varying periods of between one day and three months depending on the immediate cash requirements of the Group, earning interest at the respective short-term deposit rates.
Money market deposits are held at fair value through profit and loss and are Level 1 instruments. The fair values of money market deposits are calculated by multiplying the net asset value per share by the investment held at the balance sheet date.
