We will specify the margin percentage required on your CFD at the time that you open the CFD. However, we
reserve the right to alter that percentage during the time that the CFD remains open (including, for example, under
volatile market conditions; see section 5.15). In extreme conditions or situations percentage or per-contract margin
requirements higher than those shown in the Contract Details may apply. This happened in the market crash of
October 1987, the Kobe earthquake of 1995 and the aftermath of 11 September 2001. It could also occur if, for
example, the company to which a share CFD relates goes into receivership or insolvency. If any such event should
occur, and we increase the required margin levels as a result, we will take steps to notify you if you already have an
open CFD, or, if you wish to open a new CFD. We will notify you if we change the margin percentage on an open
CFD, and the further amount of money required from you to keep the CFD open.
