Credit Contracts and Consumer Finance Regulations 2004
Note: Please note Formula
2 (Regulation 11) has been revised. The information below
describes the new formula. The previous formula released in August
2004, has been deleted from the Regulations. It is not
applicable.
Calculation of loss on full-prepayment
formulas
Section 50 of the Credit Contracts and Consumer Finance Act
provides debtors with a right to full prepayment of a credit
contract.
The amount that a creditor may require a debtor to pay for full
prepayment must not exceed the sum of the following:
- The unpaid balance (including fees or interest charges accrued
up to the time full prepayment) calculated at the time of full
prepayment.
- Fees to cover the administrative costs relating to the
prepayment (provided such fees are authorised by the contract).
- And, a charge that does not exceed a reasonable estimate of
the creditor’s loss arising from the prepayment.

Procedure for calculating a reasonable
estimate of a creditor’s loss arising from full prepayment
The concept of “loss” in this context is based on principles of
contractual damages. Thus, “loss” includes the gains a creditor
would have made if the contract had run its course and there had not
been full prepayment.
Following contract damages principles, the “loss” is mitigated as
follows:
- The award is discounted to its present value.
- The creditor must mitigate its loss by reinvesting the amount
fully prepaid, ie the creditor must re-lend the money under a
subsequent credit contract at its prevailing interest rate. If the
prevailing rate is lower than the original rate, the creditor has
incurred a loss.
Section 54 provides for regulations to be made prescribing a
formula which the creditor may use to calculate its loss.
The formula therefore provides a “safe harbour” to the creditor so
that it can be sure it has complied with the Act, ie by correctly
applying the formula it won’t have exceeded a reasonable estimate of
its loss.

Two formulas have been provided
Formula 1
Formula 1 provides a procedure for where a contract has a single
fixed interest rate for the entire term of the contract.
The formula is based on the positive difference between the
present value of the remaining payments due on the credit contract
and the present value of the payments that would be received if the
amount fully prepaid is relent for the unexpired portion of the
contract at the creditor’s prevailing fixed interest rate.
This formula applies where the contract has an interest rate
fixed for the whole term of the contract.
A creditor may calculate a reasonable estimate of its loss with
the following formula.
Loss:
= 0 - if interest rates have not reduced
= VFP - unpaid balance if interest rates have reduced
VFP = value of forgone payments
Mathematically, VFP is expressed as follows:

Where:
f = the number of payments to be made per year under the
original contract
v =

i = the annual interest rate currently offered by the
creditor on a credit contract of the same type as the original
contract, but with a term equal or closest to the unexpired portion
of the term of the original contract
n= the number of payments yet to be made
d= the number of days since the last payment due date
p= the amount of each payment payable during the fixed
rate contract

Formula 2
Formula 2 provides a procedure for where a contract has a fixed
interest rate that applies for a period of the contract but not the
whole term (a “fixed interest period”).
This most commonly applies to a long term contract, eg during a
25 year loan it is common for debtors to “fix” the interest rate for
periods, eg one year or five years. At the end of the period, the
debtor may “re-fix” for a further period at the creditor’s
prevailing fixed interest rate, or the loan reverts to a variable
interest rate.
This formula applies where a contract is being fully prepaid
during a fixed interest period that is less than the term of the
contract.
A reasonable estimate of a creditor's loss may be calculated
thus:
Loss:
= 0 (if interest rates have not reduced)
= VFP -unpaid balance (if interest rates have reduced)
VFP is expressed as:
Where:
EBEFT is the expected balance at the end of the fixed
term, if this is known. If EBEFT is not known, then
EBEFT should be determined by a step by step accumulation of
the starting loan amount plus interest at the fixed rate, less
payments.
f = the number of payments to be made per year during
the fixed interest period in which the contract is fully prepaid
i = the annual interest rate currently offered by the
creditor on a credit contract of the same type as the original
contract, but with a term equal or closest to the unexpired portion
of the fixed interest period of the original contract
v =

n = the number of payments yet to be made during the
fixed interest period in which the contract is fully prepaid
d = the number of days since the last payment due date
p = is the amount of each payment payable under the
fixed rate contract during the fixed interest period in which the
contract is fully prepaid

Formulas do not apply in certain
circumstances
These formulas do not apply to contracts with unusual features.
For instance, payment amounts must be equal during the contract or
the fixed interest period.
Formulas must be calculated at the time full prepayment is made
by the debtor.
The formula assumes the money can be reinvested at the time of
full-prepayment.

Examples
The following examples, illustrate each formula.
Formula 1 example
At the time the contract is taken out the following variables are
relevant:
| Amount advanced |
$5000 |
| Term |
2 years |
| Payment amount (p) |
$235.37 |
| Payment frequency (f) |
monthly, ie 12 per year |
| Current Annual fixed interest rate |
12% |
The debtor fully prepays the contract after 6 months and 5 days.
The creditor's prevailing interest rate had dropped to 10%. The
relevant variables are:
| Unpaid balance |
$3865.66 |
| Days since last payment due date (d) |
5 |
| Number of remaining payments (n) |
18 |
| Creditor's prevailing interest rate (i) |
10% |
Applying the above formula:
VFP ($3924.23) - unpaid balance ($3865.66) = a
reasonable estimate of the creditor's loss ($58.87)

Formula 2 example
At the time the contract is taken out the following variables are
relevant:
| Amount advanced |
$5000 |
| Term |
2 years |
| Fixed interest period |
1 year |
| Payment amount (p)* |
$235.37 |
| Payment frequency (f)* |
monthly, ie 12 per year |
| Prevailing annual interest rate (j) |
12% |
The debtor fully prepays the contract after 6 months and 5 days.
The creditors prevailing fixed interest rate has dropped to 10%.
| Unpaid balance |
$3865.66 |
| EBEFT |
$2649.11 |
| Days since last payment due (d) |
5 |
| Number of remaining payments (n)* |
6 |
| Prevailing annual interest rate (i) |
10% |
Applying the above formula:
VFP ($3897.45) - unpaid balance ($3865.66) = a
reasonable estimate of the creditor's loss ($31.79).
*applying during the fixed rate period.

The Act allows you to use model disclosure statements prescribed
by regulations. The model disclosure statements represent the
Ministry of Consumer Affairs’ interpretation of compliance with the
disclosure standards (ie, clarity, conciseness and bringing the
information to the debtor’s attention).
The advantage of using a model disclosure statement is that a
creditor can be considered to have complied with the disclosure
standard required by Section 32. The model disclosure statements are
not compulsory and you are free to choose a different form of
disclosure. A decision by a creditor not to use a model disclosure
statement does not in itself have a bearing on whether the
performance standard for disclosure has been met.
You may also choose to adapt a model disclosure statement to suit
your particular business, rather than use the model disclosure
statement in its entirety. However, if you choose to adapt
particular items or clauses from the model disclosure statement, you
could not be said to be using the model disclosure statement. If you
choose to adapt the model disclosure statement, ensure your
adaptation still complies with the disclosure requirements.
