Members organising any club event, diving or social, are welcome to ask participants to round up their settlement of costs for the event to a suitable round figure. This rounding up amount is to be paid to the club treasurer as the Putney Volutnary Contribution (PVC) for the event. The amount rounded up is to be to the nearest one or two pounds depending on the size of the settlement. It is always to be made clear to participants that PVC is voluntary and no pressure is to be put on participants to pay this. PVC is to be accounted for separately in the annual accounts.
