The decision was made by Fatima Al Shariqi, the Rapporteur, and Salem Rashid Al Nuaimi, the Managing Member. It was published in the Official Gazette issue No. 12, page 7. The decision outlines the conditions and controls for merging the retirement service period, including the requirement that the period to be merged must have been entitled to a pension from the Fund. The retirement service period can be merged up to a maximum of the total qualifying period for pension entitlement, which is 100%. All retirement pensions disbursed from the Fund must be refunded, and the cost of merger for each month is calculated as 26% of the difference between the salary subject to retirement deduction at the time of applying for the merger and the last salary subject to deduction at retirement. The costs of the merger for the previous service period must be paid in accordance with the approved decisions and procedures. The provisions and decisions approved for the service merger period will apply in cases where no provision is stipulated in the present Decision.
