Article II 5.04 Amount of the Pension for the Surviving Spouse of a Member

  Subject to the provisions of Article II 1.13 the pension for the surviving spouse of a member shall be equal to 1.1% of the final reference salary of the deceased member based on the years of membership he would have accumulated if he had remained a member up to the applicable retirement age, subject to the applicable maximum period of membership specified in Article II 2.02. The number of years counted shall be the applicable maximum period if the death resulted from an occupational accident or occupational illness, or from saving a person.

  To the amount thus determined shall be added a fixed sum. This is given in Annex B for a pension calculated on the basis of the applicable maximum period of membership. This sum shall be reduced proportionately for a shorter period of membership and, where applicable, reduced in accordance with Article II 1.13.
