1. An insurance undertaking which has obtained an authorisation for a principal risk belonging to one class or a group of classes as set out in Annex I may also insure risks included in another class without the need to obtain authorisation in respect of such risks provided that the risks fulfil all the following conditions:
they are connected with the principal risk;
they concern the object which is covered against the principal risk; and
they are covered by the contract insuring the principal risk.
2. By way of derogation from paragraph 1, the risks included in classes 14, 15 and 17 in Part A of Annex I shall not be regarded as risks ancillary to other classes. However, legal expenses insurance as set out in class 17 may be regarded as a risk ancillary to class 18, where the conditions laid down in paragraph 1 and either of the following conditions are fulfilled:
the main risk relates solely to the assistance provided for persons who fall into difficulties while travelling, while away from their home or their habitual residence; or
the insurance concerns disputes or risks arising out of, or in connection with, the use of sea-going vessels.
