That's a good one Karthik.
I have a suggestion--nothing is mentioned reg the data retrieval/storage at the time of resignation/relieving. It could be better to mention that all data needs to be handed-over to the superior/SA as a part of the Relieving process--unless this aspect is covered elsewhere in your HR policies.
On many occasions, employees delete data [partially or completely] while handing over the laptop--especially when the parting isn't smooth.
