What Are the Advantages?
When you buy past service, you gain additional weeks of contributory service in HOOPP. This increases your overall pension at retirement.
Contributory service is a key variable in the calculation of your HOOPP pension. The more years of contributory service you have, the higher your pension will be. And, there's no limit on how much contributory service you can have.
Buying service can make as much sense for part-time employees as it does for full-timers. You'll be boosting your contributory service, based on your part-time participation in the Plan.
The Buyback Charts show the additional pension that would result from purchasing a year of past service, assuming you work on a full-time basis.
