VMware shares/RSU questions

Yoe: 15 Senior MTS (cloud BU) Package: 185k What is the RSU allocation policy ? 45 days end of joining month? Allocation cycle is 4 times in a year or based on joining date? For example: if we join 1st Oct and RSU allocation happens on 5th December (quarterly) Why the VMware share is going low? Dell spin-off cause any trouble? Good to join now or ask for more time?
