Valuation of level 3 and complex level 2 financial instruments
Refer to note 1 (i) (accounting policy) and note 23 (financial disclosures)
The key audit matter How the matter was addressed in our audit
Risk of Error: The determination of the valuation
of financial instruments that are considered to
have unobservable inputs, which represents
management’s estimate of the fair value of the
instrument at the date of the financial statements,
involves judgement and complexity surrounding
the valuation assertion. The significant pricing
inputs are unobservable, involve complex
valuation models or limited market data and
estimation uncertainty can be high. As such, we
have determined there to be a significant risk of
error around the valuation of these financial
instruments. We identified the financial
instruments with a significant risk of error to be
those that are classified as Complex Level 2
instruments (i.e., those financial instruments
valued by models deemed to have a high degree
of complexity) and those that are classified as
having significant unobservable inputs into Level
3 positions (i.e. those financial instruments valued
using alternative pricing procedures due to at least
one significant unobservable input).
• We performed end-to-end process walkthroughs of the
valuation process and tested the design, implementation
and operating effectiveness of key controls identified in
the following areas:
◦ Independent price verification (“IPV“) key
inputs, including completeness of positions and
risk factors subject to IPV;
◦ Fair value adjustments (“FVAs“);
◦ IT systems relevant to the valuation including
interfaces with risk systems and external pricing
providers; and
◦ Validation, completeness, implementation and
usage of valuation models, including controls
over adjustments to model limitations and
assumptions
• In conjunction with our valuation specialists, we:
◦ Independently valued a selection of financial
instruments in both level 2 and level 3 (to
address the risk of fraud);
◦ Performed test of details for a sample of
instruments including re-performance of
management’s process over the reliability and
accuracy of the inputs used in IPV process and
IPV calculation itself for the 31 December 2022
IPV process;
Risk of Fraud: Management makes certain
assumptions as they relate to the valuation of
financial instruments. The valuation of level 3
financial instruments takes into consideration,
among other matters, trader judgement regarding
at least one significant unobservable input. The
significant assumptions and/or judgements used
for the significant unobservable inputs are
subjective and can be manipulated by the trader.
As a result, there is an inherent fraud risk relating
to those financial instruments that are classified as
Level 3. (i.e., those financial instruments valued
using alternative pricing procedures due to at least
one significant unobservable input).
We regard the valuation of level 3 and complex
level 2 financial instruments as a key audit matter
because its calculation is complex and requires a
high degree of management judgement.
◦ Inspected external sources for price inputs used
by management in performing IPV and
recalculated IPV variances as well as FVAs; and
◦ Independently obtained key pricing inputs as
part of our recalculations and challenge.
Overall, we found the valuations of level 3 and more
complex level 2 financial instruments, including the
significant pricing inputs, to be reasonable.
