Explanatory note
This note is not part of the regulations, but is intended to indicate their general effect.
These regulations, which come into force on 1 December 2010, prescribe various matters for the purposes of Part 5D of the Reserve Bank of New Zealand Act 1989 (the Act), which relates to the prudential regulation of deposit takers.
The regulations—
specify the type of credit rating that a deposit taker is required to have:
require every deposit taker and trustee to ensure that the deposit taker's trust deed includes the minimum capital ratio that the deposit taker must maintain:
specify that the minimum capital ratio that must be included in the trust deed is not less than 8% if the deposit taker has a credit rating under the Act and not less than 10% if it does not have such a credit rating:
set out how the minimum capital ratio must be calculated:
declare additional classes of persons to be related parties of deposit takers for the purposes of Part 5D:
require every deposit taker and trustee to ensure that the deposit taker's trust deed includes a maximum limit on aggregate exposures to related parties relative to capital, fixed by agreement between the deposit taker and trustee:
provide that the maximum limit on related party exposures included in the trust deed must not exceed 15%:
set out how the maximum limit on related party exposures must be calculated.
The regulations are organised into 5 parts as follows:
Regulations 1 and 2 relate to the title and commencement of the regulations.
Part 1: preliminary provisions
Regulation 3 defines terms used in the regulations. The Act also defines a number of terms used in the regulations.
The effect of regulation 3(4) is that if a term is used in the regulations but is not defined and that term has a meaning according to generally accepted accounting practice, then the term must be given the meaning according to generally accepted accounting practice.
Regulation 4 restates the statutory definition of related party and extends that definition so that any related party of a member of the borrowing group is treated as also being a related party of the deposit taker for the purposes of Part 5D. The following classes are also added:
sister entities of the deposit taker or any member of the borrowing group:
persons in which the deposit taker or any member of the borrowing group has a substantial interest (which, in essence, is 10% control over the entity or control or significant influence over 25% of the board composition):
persons with which the deposit taker or a group member (or a person with a substantial interest in the deposit taker or group member) have interlocking boards (in essence, 40% common membership).
The extended definition of related party applies for the purposes of Part 5D of the Act. The term is used in section 157L of the Act (which relates to governance requirements for deposit takers) and in sections 157V to 157Y of the Act and Part 4 of these regulations (which impose limits on aggregate related party exposures).
Regulation 5 provides that where a deposit taker is a member of a borrowing group, every calculation that the regulations require a deposit taker to make must be made on a consolidated basis for the deposit taker's borrowing group.
Part 2: requirements relating to credit ratings
Regulation 6 requires the rating of creditworthiness that a deposit taker must have from an approved rating agency under section 157I of the Act to be a local currency (New Zealand dollar), long-term, issuer rating. These are the same requirements as prescribed by the Deposit Takers (Credit Ratings) Regulations 2009 (which are revoked by these regulations). A long-term issuer rating expresses an opinion about the overall capacity of a deposit taker to meet its financial obligations (in contrast to an issue rating, which relates only to a specific financial obligation).
Part 3: requirements relating to maintenance of minimum capital ratio
This Part sets out the regulations needed under sections 157S to 157U of the Act.
Regulation 8 requires every deposit taker and trustee to ensure that the deposit taker's trust deed includes the minimum capital ratio that the deposit taker has to maintain. This must be not less than 8% if the deposit taker has a credit rating under section 157I of the Act and not less than 10% if the deposit taker does not have such a credit rating.
Regulation 9 provides that the capital ratio must be calculated as the ratio (expressed as a percentage) of the deposit taker's capital (calculated as set out in regulation 10) to the sum of 2 amounts: its risk-weighted amount for credit risk (calculated as set out in regulation 11) and its aggregate amount for market risk and operational risk (calculated as set out in regulation 21). If the deposit taker has a borrowing group, the calculation must be done on a consolidated basis.
To calculate its risk-weighted amount for credit risk, the deposit taker must classify each of its on-balance sheet exposures into the first class that applies to the asset in table 1 of the Schedule (unless the asset is a loan secured over more than 1 form of security) and then multiply the value of each asset by the risk-weight that applies to that class set out in the second column of the table. The resulting total amount for risk-weighted on-balance sheet exposures must then be added to the deposit taker's following off-balance sheet exposures: direct credit substitutes, asset sales with recourse, and forward asset purchases. In the case of a loan secured over more than 1 form of security, instead of classifying that asset into the first class that applies in table 1, it must be classified into the class that refers to one of those forms of security and that produces the highest risk weight. Regulations 12 to 20 contain more detailed provisions about when certain assets must be included in the calculation of risk-weighted on-balance sheet exposures and requirements that must be satisfied before certain on-balance sheet assets are able to be classified into various of the classes listed in table 1.
Regulation 21 sets out a formula for calculation of the deposit taker's aggregate amount of market risk and operational risk. Two values need to be determined to apply the formula: the deposit taker's total assets (taken from the book value) and the deposit taker's risk-weighted amount for credit risk (taken from the calculation made under regulation 11).
Part 4: restrictions on related party exposures
This Part sets out the regulations needed to implement sections 157V to 157Y of the Act. The combined effect of the Act and these regulations is to require deposit takers and trustees to include an agreed maximum limit on aggregate exposures to related parties in the trust deed of no more than 15% of capital (expressed as a ratio). It is a limit on aggregate related party exposures, not a limit on exposures to individual related parties. If the deposit taker is part of a borrowing group, the ratio must be calculated on a consolidated basis so that it captures exposures of every member of the borrowing group to a related party of any member of the borrowing group and applies relative to the consolidated capital of the borrowing group.
Regulation 24 sets out the ratio calculation. For the purposes of that calculation, the related party exposures must be identified in accordance with regulation 25 and measured in accordance with regulations 26 and 27. Regulation 25 requires the inclusion of not just the standard forms of lending, but all on- and off-balance sheet exposures. Exposures of a capital nature are excluded because they are required to be deducted from capital. Regulation 26 requires the full potential exposure to be measured. However, market-related contracts must be measured under regulation 27 by applying a credit conversion factor that is intended to approximate their replacement cost over the lifetime of the contract.
Part 5: revocation
Regulation 28 revokes the Deposit Takers (Credit Ratings) Regulations 2009.
