. Korat does. Just done my 4th 90 report on mine. It now ends just over one months time on 9th July.
It would appear that if you report early, you actually lose the remaining days..... Not counted from when you should have reported.!.!
Unlike your one year extension which is the same date every year regardless of when you renew it.
No big deal as there is no charge for the 90 reports.
