One has to remember that the recipients of the early retirement will have to pay a certain portion of the money they received to Inland Revenue unless their positions are made redundant.
The formula for the early retirement scheme would probably be the same as SIA's back in 2003 i.e. 1 month of last drawn salary for every year of service up to a maximum of 25 months. The closer the staff is to the retirement age, in this case is 62, the lesser one will be paid. I was paid the maximum of 25 months of my last drawn salary in 2003 when I had 5 years of service left. Some of my older colleagues got less than me.
Good luck to SATS and its staff!
