I am 60 next April and have been toying with staying on possibly an extra month so as not to dip into more savings than I need to as I am paid weekly but pensions are paid at the end of each month as I understand it. The trouble is that the Pension Supplement would not be paid "If you remain in Company employment or if you are re-employed" (taken from section C booklet), so. in my case, April's end-of-month pension payment would not include the pension supplement, should I stay on, but the May payment would - so far so good.
For the lump sum entitlement (maximum tax-free of RM pension pot inc AVC), the pension supplement would be included in the calculation if you are entitled to draw it i.e. if you leave service up to and including pension day payment (-1 day) according to the email response I got today. But if you leave service after you have taken your first pension payment then the value of your RM pension pot will not include the pension supplement and will not be revised once the supplement is payable. Worth bearing in mind for anyone in a similar situation to myself.
Am now thinking about increase my AVC payments into Zurich for the remaining months I have in RM to maximise my tax-free lumper and not to delay retirement past my 60th and enjoy spring and early summer.
