(a) derive the risk weighted matched position in the time band (which is either the lesser of the sum of the absolute
values of the Financial Assets and the sum of the absolute values of the Financial Liabilities in that time band, or, if
those sums are equal, that sum, multiplied by the risk weight for that time band);

(b) derive the risk weighted value of the Rate Insensitive Retail Products in that time band (which is the sum of the
absolute values of the Rate Insensitive Retail Assets and Rate Insensitive Retail Liabilities in that time band
multiplied by the risk weight for that time band);

(c) if the risk weighted matched position is less than or equal to the risk weighted value of the Rate Insensitive Retail
Products in a time band, then the vertical disallowance amount for that time band is the risk weighted matched
position multiplied by 20%;

(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 that 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 any;

(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 a
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;
