PART II CALCULATION OF CHILD SUPPORT MAINTENANCE

2 Calculation of amounts
1 Where any amount is to be considered in connection with any calculation made under these Regulations or under Schedule 1 to the Act, it shall be calculated as a weekly amount and, except where the context otherwise requires, any reference to such an amount shall be construed accordingly.
2 Subject to paragraph (3), where any calculation made under these Regulations or under Schedule 1 to the Act results in a fraction of a penny that fraction shall be treated as a penny if it is either one half or exceeds one half, otherwise it shall be disregarded.
3 Where the calculation of the basic rate of child support maintenance or the reduced rate of child support maintenance results in a fraction of a pound that fraction shall be treated as a pound if it is either one half or exceeds one half, otherwise it shall be disregarded.
4 In taking account of any amounts or information required for the purposes of making a maintenance calculation, the Secretary of State shall apply the dates or periods specified in these Regulations as applicable to those amounts or information, provided that if he becomes aware of a material change of circumstances occurring after such date or period, but before the effective date, he shall take that change of circumstances into account.
5 Information required for the purposes of making a maintenance calculation in relation to the following shall be the information applicable at the effective date—
(a) the number of qualifying children;
(b) the number of relevant other children;
(c) whether the non-resident parent receives a benefit, pension or allowance prescribed for the purposes of paragraph 4(1)(b) of Schedule 1 to the Act;
(d) whether the non-resident parent or his partner receives a benefit prescribed for the purposes of paragraph 4(1)(c) of Schedule 1 to the Act; and
(e) whether paragraph 5(a) of Schedule 1 to the Act applies to the non-resident parent.

3 Reduced Rate
The reduced rate is an amount calculated as follows—
F+(A×T)
where—
F is the flat rate liability applicable to the non-resident parent under paragraph 4 of Schedule 1 to the Act;
A is the amount of the non-resident parent’s net weekly income between £100 and £200; and
T is the percentage determined in accordance with the following Table—
	1 qualifying child of the non-resident parent				2 qualifying children of the non-resident parent				3 or more qualifying children of the non-resident parent			
Number of relevant other children of the non-resident parent	0	1	2	3 or more	0	1	2	3 or more	0	1	2	3 or more
T (%)	25	20.5	19	17.5	35	29	27	25	45	37.5	35	32.5

6 Apportionment
If, in making the apportionment required by regulation 4(3) or paragraph 6 of Part I of Schedule 1 to the Act, the effect of the application of regulation 2(2) (rounding) would be such that the aggregate amount of child support maintenance payable by a non-resident parent would be different from the aggregate amount payable before any apportionment, the Secretary of State shall adjust that apportionment so as to eliminate that difference; and that adjustment shall be varied from time to time so as to secure that, taking one week with another and so far as is practicable, each person with care receives the amount which she would have received if no adjustment had been made under this paragraph.

7 Shared care
1 For the purposes of paragraphs 7 and 8 of Part I of Schedule 1 to the Act a night will count for the purposes of shared care where the non-resident parent—
(a) has the care of a qualifying child overnight; and
(b) the qualifying child stays at the same address as the non-resident parent.
2 For the purposes of paragraphs 7 and 8 of Part I of Schedule 1 to the Act, a non-resident parent has the care of a qualifying child when he is looking after the child.
3 Subject to paragraph (4), in determining the number of nights for the purposes of shared care, the Secretary of State shall consider the 12 month period ending with the relevant week and for this purpose “relevant week ” has the same meaning as in the definition of day to day care in regulation 1 of these Regulations.
4 The circumstances in which the Secretary of State may have regard to a number of nights over less than a 12 month period are where there has been no pattern for the frequency with which the non-resident parent looks after the qualifying child for the 12 months preceding the relevant week, or the Secretary of State is aware that a change in that frequency is intended, and in that case he shall have regard to such lesser period as may seem to him to be appropriate, and the Table in paragraph 7(4) and the period in paragraph 8(2) of Schedule 1 to the Act shall have effect subject to the adjustment described in paragraph (5).
5 Where paragraph (4) applies, the Secretary of State shall adjust the number of nights in that lesser period by applying to that number the ratio which the period of 12 months bears to that lesser period.
6 Where a child is a boarder at a boarding school, or is a patient in a hospital, the person who, but for those circumstances, would otherwise have care of the child overnight shall be treated as providing that care during the periods in question.
