1.20 As there are differences in the size and category of the PFI prisons, no two penalty performance systems are the same. For example, Ashfield and Rye Hill have low quarterly baseline totals compared to Forest Bank and Altcourse. When a prison incurs more points than the baseline, the Commissioner for Correctional Services begins to make financial deductions from the annual payment. Therefore, when trying to compare the performance of PFI prisons, it is necessary to compare the percentage deduction of the annual payment rather than the number of performance penalty points. Different levels of fines exist for escapes from similar types of establishment.
