a price variation trigger specified in the determination has happened; or
in a case where the determination is in terms of a maximum total amount (expressed in the form of a revenue yield cap) that may be earned by the airport licensee in question from the provision of aeronautical services and facilities, the Authority is satisfied that there has been a material change in the cost conditions or capital expenditure requirements for the provision of the aeronautical services and facilities and security services and facilities by the airport licensee, and that the change was brought about by external events not reasonably foreseeable by and beyond the control of the airport licensee.
