12. 27 August 2003 - cp EPTAB5 12 Rental scheme – compromise proposal Rental fee based on Average purchase price (VAM) Estimated useful lifetime Likely maintenance charges (guarantee period, repair contract) Likely usage Costs monitored regularly Verification after rental Repairs When costs exceed revenue - action! Full or partial renewal of stock New equipment, new guarantee Equivalent function with lower maintenance costs Modification of level of support Increase in rental fee Declassification Rental fee may change – (annual review?) Excessive costs (increase) New purchases (VAM) (increase or decrease)

13. 27 August 2003 - cp EPTAB5 13 Rental scheme – compromise proposal Advantages Simplifies existing procedures Based on support and utility to users Allows the revenue to cover real costs Automatic regulation of overall rental Implies close monitoring of revenue and costs Transparency Via EPTAB/EAB
