Paragraphs 3 and 4 of Article IX (Related Persons) of the Convention shall be deleted and replaced by the following: “3. Where an adjustment is made or to be made by a Contracting State in accordance with paragraph 1, the other Contracting State shall (notwithstanding any time or procedural limitations in the domestic law of that other State) make a corresponding adjustment to the income, loss or tax of the related person in that other State if:

(a) It agrees with the first-mentioned adjustment; and (b) Within six years from the end of the taxable year to which the first-mentioned adjustment relates, the competent authority of the other State has been notified of the firstmentioned adjustment. The competent authorities, however, may agree to consider cases where the corresponding adjustment would not otherwise be barred by any time or procedural limitations in the other State, even if the notification is not made within the six-year period.

  1. In the event that the notification referred to in paragraph 3 is not given within the time period referred to therein, and the competent authorities have not agreed to otherwise consider the case in accordance with paragraph 3(b), the competent authority of the Contracting State which has made or is to make the first-mentioned adjustment may provide relief from double taxation where appropriate.”
