General and Administrative Expenses
General and administrative expenses show a decrease to £4.1 million from £4.2 million after adjustments under IFRS for currency effects and charges on employee options. Movements in the fair value of currency contracts and gains on inter-group balances have produced a benefit of £0.7 million against a cost of £0.4 million in the corresponding six month period. This is offset by an increase in option charges of £0.2 million between the two periods. Underlying general and administrative expenses are therefore increasing in line with expectations as additional resources in sales and marketing and regulatory capability have been added.
