Article 69 4.

If, after the initial period referred to in paragraph 1, the available financial means diminish below the target level specified in that paragraph, the regular contributions calculated in accordance with Article 70 shall be raised until the target level is reached. After the target level has been reached for the first time and where the available financial means have subsequently been reduced to less than two-thirds of the target level, those contributions shall be set at a level allowing for reaching the target level within six years.
