2.7 Full potential earnings in a month are not paid to Land Securities Trillium if performance drops below 95 per cent of contractual obligations, as measured using the performance measurement system. In the expanded contract, that score for PRIME estate will rise to 97 per cent over the three year period to 2007. In addition, the PRIME performance measurement system simply made deductions for poor performance and did not provide incentives to recover standards. The new system will do so. Following a performance deduction, if Land Securities Trillium delivers a performance score in excess of 95 per cent for three months it can earn back 90 per cent of the deductions for the period in which they applied. The 95 per cent threshold for winning back performance deductions will though rise in line with the threshold for performance deductions.
