Eighth Schedule

Measurement of Market Risk Exposure

Aggregate Interest Rate Exposure

1. The Registered Bank shall derive the amount of Aggregate Interest Rate Exposure of the Banking Group in accordance with either:

   (a) clauses 2 to 7 of this Schedule; or

   (b) any other method, but only if the Aggregate Interest Rate Exposure derived in accordance with that method is not, in the opinion of the Registered Bank (such opinion to be based on reasonable grounds), Materially lower than the amount derived pursuant to clause 1(a) of this Schedule.

2. Interest Rate Exposure in a Single Currency—Interest Rate Exposure in a single currency is the total of:

   (a) the directional interest rate risk;

   (b) the vertical disallowance; and

   (c) the horizontal disallowance;

   in that currency.

3. Exposure to Directional Interest Rate Risk in a Single Currency—(1) The amount of directional interest rate risk in a single currency shall be derived by subtracting the aggregate amount of the change in the value of each Financial Liability (excluding equity instruments) of the Banking Group arising from a directional change in interest rates in that currency from the aggregate amount of the change in the value of each Financial Asset (excluding equity instruments) of the Banking Group, arising from a directional change in interest rates in that currency.

   (2) The value of a Financial Instrument is:

   (a) in the case of an unrecognised Financial Instrument and a recognised Financial Instrument which is a market related contract, the face or contract amount of the Financial Instrument expressed in New Zealand dollars using the relevant spot exchange rate; and

   (b) in the case of other Financial Instruments, the carrying amount of the Financial Instrument expressed in New Zealand dollars using the relevant spot exchange rate.

   (3) The change in the value of a Financial Instrument is derived by multiplying the value, or proportion of the value, of the Financial Instrument allocated to the applicable time band specified in Table 1, in accordance with clause 3(4), by the risk weight specified for that time band in Table 1.

   Table 1: Time Bands, Risk Weights, and Assumed Interest Rate Changes

   Time Bands	up to 1-6 mths	6-12 mths	1-2 yrs	2-4 yrs	4-6 yrs	6-10 yrs	Over 10 yrs
   Assumed Interest Rate	1.0	1.0	0.9	0.8	0.7	0.6	0.6
   Change(%)
   Risk weights (%)	0	0.3	0.7	1.3	2.0	3.0	3.5

   (4) Subject to clauses 3(5) and 3(6) of this Schedule, the value of each Financial Instrument, or a proportion of it, shall be allocated to the time band specified in Table 1 in a manner which the Registered Bank believes, on reasonable grounds, reflects the date on which the interest rate applicable to the Financial Instrument, or proportion of the Financial Instrument, will be altered, or the date at which the principal, or a proportion of the principal, will be paid, notwithstanding the Interest Rate Repricing Date of the Financial Instrument.

   (5) Notwithstanding clause 3(4) of this Schedule:

   (a) A Registered Bank may exclude from the application of clause 3(4) of this Schedule the value, or the appropriate proportion of the value, of those Financial Instruments which meet the netting criteria contained in clause 4; and

   (b) the aggregate value, or the appropriate proportion of the aggregate value, of all Rate Insensitive Retail Assets and of all Rate Insensitive Retail Liabilities shall be allocated to the time bands specified in Table 2 in accordance with the percentages set out in Table 2.

   Table 2: Allocation of the value of Rate Insensitive Retail Products across time bands

   Time Bands	up to 1 mth	1-6 mths	6-12 mths	1-2 yrs	2-4 yrs	4-6 yrs
   Percentage of aggregate	5%	5%	10%	20%	40%	20%
   value

   (6) A Registered Bank may exclude the value of options and, instead, use its own methodology to determine the Interest Rate Exposure in any currency arising from options and add the amount so derived to the total Interest Rate Exposure in that currency.

4. Netting Criteria—A Registered Bank may exclude the value of Financial Instruments in respect of which it has matched positions which meet any one of the following criteria:

   (a) the matched position comprises the same Financial Instruments with the same issuer, coupon, currency and maturity; or

   (b) (i) with respect to matched positions comprising futures, the underlying Financial Instruments to which the futures relate must:

   (A) be for the same product;

   (B) have the same value or notional value;

   (D) mature within seven days of each other; or

   (ii) with respect to matched positions comprising swaps (including separate legs of different swaps) or FRAs, the underlying Financial Instruments to which the swaps or FRAs relate must:

   (C) be denominated in the same currency;

   (D) have reference rates (for floating rate positions) which are identical;

   (E) have coupon rates which are identical or which do not differ by more than 15 basis points; and
