What changes on the sixth day
On the sixth day of each month, myMOM Portal updates the organisation’s nationality shares for C3, local PMET share for C4 and total PMET count for the small-organisation default-points assessment. MOM averages the latest three months of available data to reduce abrupt movements.
MOM’s May example
The 6 May update uses January, February and March. April is excluded because April CPF contributions are collected in May; April workforce data can first appear in the 6 June update. The displayed profile therefore follows the available-data schedule rather than an immediate snapshot of current staff.
