My salary as shown in payslip is made up of two components :
1. Base pay
2. Benefits funding
To clarfiy more on 'Benefits Funding' : my company gives 10% of base pay as benefits component, which you can use to fund benefits like pension, insurance etc.
My package as shown in contract is only made up of 'Base Pay' but unfortunately it does not qulaify me for extension, though clubbed with 'Benefits Funding', I just make it

Am I good with my payslips or should I start looking for job back home

Cheers,
nks
