        INCENTIVE BASED REGULATION - Incentive based reg-
        ulation or performance-based regulation is designed      Generation mix
        with a ‘penalty and reward’ structure.  The regulator
        sets a performance target to be achieved by a Licensee
        and when the Licensee exceeds the target, it retains
        the financial benefit. Performance targets include;-


        •   Distribution operation and Maintenance costs
        •   Days Lag
        •   Target Uncollected Debt Factors
        •   Distribution efficiency
        •   Distribution loss factor
