In most cases this will be your pensionable 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, the final pensionable pay from one of those earlier periods could be substituted. This protects your pension if you have a reduction in pay 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. If at any time you have worked part-time, the starting point for assessment of your pension is to use the pensionable pay you would be able to count if whole-time.
