Duplication of work performed by banks’ internal audit


The long-form review (LFR) currently includes the re-performance of procedures already performed by the banks’ internal audit and independent
validation units.
This Office (SARB) has accordingly requested the external auditors to make every effort to avoid duplicating work. However, substantive and reperformance tests should still be done and reliance may be placed on internal audit and independent validation work performed by the bank to minimise
the duplication of work. The external auditors should apply the International Standard on Auditing 610-principles to assess the level of reliance it can place
on the internal work performed by the bank. The degree of reliance that may be placed on the work done by the bank needs to be agreed on between the
external auditors and the bank. The external auditors should report to both this Office and the bank the level of reliance they have placed on work
performed by internal auditors and independent validation units. This report should include the effectiveness of these functions.
Reliance
Where possible, the attestation should be based on the review of statutory and regulatory audit papers and previous LFR completed which cover similar
processes and controls. Where reliance is placed on statutory or regulatory audits, or previous LFR workings, reference should be made to the audit reports
and/or LFR, and working papers and findings should be included as part of the LFR.

Sample Size
A random sample consisting of at least five exposures should be used in the relevant LFR attest procedures. However, where a sample of five is not satisfactory,
further testing should be performed, and a larger sample size should be selected to complete the attest procedure. The portfolio size, model segmentation and
the requirements of the attest procedure should be taken into account when selecting the sample size.

based on the economic effects
of the instruments and not the
legal construction of the said
instruments. Although the legal
construction of guarantees may
differ from credit derivative
instruments, only credit-default
swaps and total-return swaps
that provide credit protection
equivalent to guarantees shall
be recognised as credit riskmitigation
instruments,

addition to credit linked notes,

(B) When a bank buys credit
protection through a totalreturn swap and records the net
payments received on the swap
as net income, but does not
record
the
offsetting
deterioration in the value of the
asset that is protected, either
through a reduction in fair value
or an adjustment to reserves,
the credit protection shall not
be recognised.
(vi) Materiality thresholds
(A) Normally, a materiality
threshold is specified in a creditderivative contract in order to
ensure that the protection seller
is obliged only to make payment
in terms of the credit-derivative
contract once a material default
has occurred in respect of an
underlying asset, reference
asset or reference entity.
However, the economic effect
of a materiality threshold
specified in a credit-derivative
contract may be that the
protection buyer will suffer a
specified amount of loss before
payment in terms of the credit
derivative contract is triggered
or the amount of payment by
the protection seller to the
protection buyer may even be
reduced. Materiality thresholds
specified in a credit-derivative
contract may therefore result in
a significant loss being incurred
by the protection buyer on an
underlying asset or reference
asset without a credit event

(A) Normally, credit-derivative
instruments provide for either
physical settlement or cash

(B)
Some

instrument is a fixed amount,

Wrong way risk: It is possible for the
counterparty's credit quality to be
co-dependent with the level of
exposure. This effect is called
wrong-way risk if the exposure
tends to increase when the
counterparty credit quality gets
worse. ISDA (the International
Swaps and Derivatives Association)
defines wrong-way risk as the risk
that occurs when "exposure to a
counterparty is adversely correlated
with the credit quality of that
counterparty". The terms 'wrongway risk' and 'wrong-way exposure'
are often used interchangeably.

forward contract with a gold
producer in which the bank pays the
spot price of gold and receives a
fixed price. Suppose the price of
gold were to decrease. That would
worsen the credit quality of the gold
producer, since their revenues
would decrease, making their
business less profitable and viable. It
would also increase the value of the
forward contract to the bank, since
the bank is paying the spot price;
therefore, the bank's exposure
would increase. If these two effects
tend to happen together, then that
co-dependence will increase the
CVA on the forward contract and it
will make the CVA larger than if the
effects were independent. The data
to quantify these co-dependencies
are difficult to obtain, and are
ephemeral. But it is important that
the CVA framework be able to

(ii) risk management process

Attest procedures
9.1 The Bank has documented how
it has complied with the use test for
the rating, PD, LGD and EAD models
9.1.1.1 Inspect the bank’s documentation and
hold discussions with management to confirm
how it has used the output of the risk
estimation systems and processes (ratings, PD,
LGD and EAD) in each criteria indicated (e.g.
Policy documentation indicating requirements
for compliance with the use test /
management reports indicating actual
compliance).
Bank practice and Findings
Where the bank uses the output of a separate
(not used for regulatory reporting) risk
estimation system for any one of the criteria,
document management’s reasoning for this.
9.1.1.2 Confirm the bank’s documented
compliance with the use test through
inspection and documentation of reports &
minutes of meetings of relevant committees
responsible for the decision making related to
each of the criteria stated, ensuring that the
output of the risk estimation systems is
considered at these committees.
