(d) if the risk weighted matched position is greater than the risk weighted value of the Rate Insensitive Retail Products in a time band, then the vertical disallowance amount for that time band is;

(i) the risk weighted value of the Rate Insensitive Retail Products multiplied by 20%; plus

(ii) the difference between the risk weighted matched position and the risk weighted value of the Rate Insensitive Retail Products, multiplied by 5%.

(3) The vertical disallowance in a currency shall have the same sign (positive or negative) as the directional risk calculated for that currency.

6. The Amount of Horizontal Disallowance in a Single Currency

(1) The amount of horizontal disallowance in a single currency shall be calculated in accordance with clauses 6 (2) to 6 (6).

(2) Allocate the time bands specified in Table 1 of this Schedule to the three time zones specified in Table 3:

Table 3: Time zones

(3) Calculate the amount of the intra-zone disallowance in each time zone as follows:

(a) derive the risk weighted net position in each time band (which is the amount of the risk weighted Financial Assets less the amount of the risk weighted Financial Liabilities in that time band). If the risk weighted net position in a time band is positive, this is a risk weighted long position and if it is negative, this is a risk weighted short position;

(b) derive the aggregate risk weighted long position in each time zone (which is the sum of any risk weighted long positions in the time bands in that time zone) and the aggregate risk weighted short position in each time zone (which is the sum of any risk weighted short positions in the time bands in each time zone);

(c) derive the matched position in each time zone (which is either the lesser of the absolute value of the aggregate risk weighted long position and the absolute value of the aggregate risk weighted short position in that time zone, or, if the absolute values of those positions are equal, that absolute value), if;

(d) the amount of intra-zone disallowance in a time zone is the value of the matched position in that time zone multiplied by the disallowance factor for that time zone specified in Table 4. If there is no matched position in that time zone, the amount of the intra-zone disallowance in that time zone is zero.

Table 4: Intra-zone disallowances

(4) Calculate the amount of the inter-zone disallowances as follows:

(a) inter-zone disallowances are derived in the following order; time zones 1 and 2, 2 and 3, and 1 and 3. The inter-zone disallowance factors which must be used to derive the inter-zone disallowance amounts are specified in Table 5;

Table 5: Inter-zone disallowances

(b) derive the residual position in each time zone (which is the net amount of the aggregate risk weighted long position and the aggregate risk weighted short position). If the residual position is positive this is a residual long position and if it is negative this is a residual short position;

(c) there is a matched position between time zones 1 and 2 if there is a residual long position in one time zone and a residual short position in the other. The matched position is either the smaller of the absolute value of the residual long position and the absolute value of the residual short position, or, if the absolute values of those positions are equal, that absolute value. If there is no matched position, the amount of horizontal disallowance is zero. If there is a matched position, then the amount of horizontal disallowance between time zones 1 and 2 is the value of the matched position multiplied by the disallowance factor for time zones 1 and 2 specified in Table 5;

(d) derive the net residual position in time zone 2, by taking the difference between the absolute value of the residual position in time zone 2 and the matched position between time zones 1 and 2, and allocating to that amount, if any, the sign of the residual position in time zone 2 (if the net residual position in a time zone is positive this is a net residual long position and if it is negative this is a net residual short position);

(e) there is a matched position between time zones 2 and 3 if there is a net residual long position in time zone 2 and a residual short position in time zone 3 or a net residual short position in time zone 2 and a residual long position in time zone 3. The matched position is either the smaller of the absolute value of those residual positions, or, if the absolute values of those positions are equal, that absolute value. If there is no matched position, the amount of the horizontal disallowance is zero. If there is a matched position then the amount of horizontal disallowance between time zones 2 and 3 is the value of the matched position multiplied by the disallowance factor for time zones 2 and 3 specified in Table 5;

(f) derive the net residual position in time zone 1 and in time zone 3:

(i) in time zone 1, by taking the difference between the absolute value of the residual position in time zone 1 and the matched position between time zones 1 and 2, and allocating to that amount, if any, the sign of the residual position in time zone 1;

(ii) in time zone 3, by taking the difference between the absolute value of the residual position in time zone 3 and the matched position between time zones 2 and 3, and allocating to that amount, if any, the sign of the residual position in time zone 3,

(if the net residual position in a time zone is positive this is a net residual long position and if it is negative this is a net residual short position);

(g) there is a matched position between time zones 1 and 3 if there is a net residual long position in one time zone and a net residual short position in the other. The matched position is either the smaller of the absolute value of the net residual long position and the absolute value of the net residual short position.
