(2)Given it is necessary to provide institutions that apply the delta-plus approach the possibility of treating non-continuous options in a more risk-sensitive way, institutions should be able to combine the approaches provided for the measurement of the risk of options and warrants under certain conditions, not only within groups but also within single legal entities. Nevertheless, in order to avoid the possibility of selective application of approaches by institutions with the view to minimizing their own funds requirements, the combination of approaches on an individual basis should only be allowed on the condition that institutions specify the scope of application of each approach before beginning to use it, so as to apply it consistently over time.
