horserun + engine out
you get half the allowance for the first 2 years as an SO. The allowance varies as it is linked to some hkg property price index. At the moment I think it is around 48, so you would get 24 for first 2 years.
From 2 years on until 8years in the company you get the allowance, 48 right now. From 8years until CN you get an amount half way between the allowance and CN allowance(73?). So you would get around 60K. Then as CN you get the CN allowance, currently 73ish?
Note, whilst you are getting the lower allowance 24 then 48, you pay nothing out of your pocket. If you choose to go above that 48 to 60 as 8year employee, or 73 as CN, you pay 8% of the rent out of your pocket.
Once you have a lease or morgage, the amount you receive is locked in for 2 years usually. After 2 years you can then rent/buy for whatever the current allowance is.
