What is final pensionable pay? For parity with part-time and whole-time regular firefighters, the pensionable pay used in the pension formula for a retained firefighter will be the final pensionable pay that would have been used for a regular whole-time firefighter in a similar role and with similar qualifying service. In most cases this would be the (whole-time) pensionable pay: "reference pay": averaged over the last 365 days of pensionable service. It would not, however, include those payments which have been treated as pensionable for providing “Additional Pension Benefits”. If either of the two preceding periods of 365 days would produce a greater amount because of a reduction in reference pay, the final pensionable pay from one of those earlier periods could be substituted. This protects your pension if you have, say, a demotion in your last couple of years' service. If you have a reduction in pay earlier on in your service, the "two pension option" could help you.
