  "text": "(1) For the purposes of regulation 60, C is calculated in relation to a tariff category as follows.\n(2) For the purposes of this paragraph—\n(a) the first test is met in relation to an assessment date if, as at that assessment date, the forecast for expenditure in relation to that tariff category exceeds the figure specified in relation to that date in the second column of the table in this Schedule which is applicable to that tariff category;\n(b) the second test is met in relation to an assessment date if, as at that assessment date, the increase in expenditure forecast applicable to that tariff category is at least 50% of, but less than 150% of, the figure specified in the third column of the table in this Schedule which is applicable to that tariff category (“the anticipated increase figure”);\n(c) the third test is met in relation to an assessment date if, as at that assessment date, the increase in expenditure forecast applicable to that tariff category is at least 150% of the anticipated increase figure;\n(d) in relation to an assessment date other than the assessment date which falls on 30th April 2017, the fourth test is met if during the tariff period that immediately preceded the tariff period in which the assessment date falls, the value of C applicable to that tariff category was 0.10 or more.\n(3) C is 0 unless the circumstances set out in sub-paragraph (4) or (5) (a), (b) or (c) apply.\n(4) In relation to the assessment date which falls on 30th April 2017, C is 0.10 if—\n(a) the first test is met; and\n(b) the second or third test is met.\n(5) In relation to any subsequent assessment date—\n(a) C is 0.10 if—\n(i) the first test is met; and\n(ii) the second test is met, whether or not the fourth test is met;\n(b) C is 0.10 if in relation to the assessment date—\n(i) the first test is met; and\n(ii) the third test is met but the fourth test is not met; and\n(c) C is 0.20 if in relation to the assessment date—\n(i) the first test is met;\n(ii) the third test is met; and\n(iii) the fourth test is met.\nTable 1\nTotal expenditure\nAssessment date\nTotal expenditure anticipated for subsequent year (£million)\n30th April
