R5540.9 As an exception to paragraph R5540.7, Key Sustainability Assurance Leaders
whose continuity is especially important to assurance quality may, in rare cases
due to unforeseen circumstances outside the Firm’s control, and with the
concurrence of Those Charged with Governance, be permitted to serve an
additional year as a Key Sustainability Assurance Leader as long as the threat to
Independence can be eliminated or reduced to an Acceptable Level.
5540.9 A1 For example, a Key Sustainability Assurance Leader may remain in that role on the
Sustainability Assurance Team for up to one additional year in circumstances where, due
to unforeseen events, a required rotation was not possible, as might be the case due to
serious illness of the intended Engagement Leader. In such circumstances, this will
involve the Firm discussing with Those Charged with Governance the reasons why the
planned rotation cannot take place and the need for any safeguards to reduce any threat
created.
R5540.10 If a Sustainability Assurance Client becomes a Public Interest Entity, a Firm shall
take into account the length of time44 an individual has served the Sustainability
Assurance Client as a Key Sustainability Assurance Leader or Key Audit Partner
before the client becomes a Public Interest Entity in determining the timing of the
rotation. If the individual has served the Sustainability Assurance Client as a Key
Sustainability Assurance Leader or Key Audit Partner for a period of five
cumulative years or less when the client becomes a Public Interest Entity, the
number of years the individual may continue to serve the client in the capacity of a
Key Sustainability Assurance Leader before rotating off the Sustainability
Assurance Engagement is seven years less the number of years already served.

Sustainability Assurance Client as a Key Sustainability Assurance Leader or Key
Audit Partner for a period of six or more cumulative years when the client becomes
a Public Interest Entity, the individual may continue to serve in the capacity of a
Key Sustainability Assurance Leader with the concurrence of Those Charged with
Governance for a maximum of two additional years before rotating off the
Sustainability Assurance Engagement.
R5540.10a If a Firm has previously performed Sustainability Assurance Engagements for a
Sustainability Assurance Client that is a Public Interest Entity and these
engagements were not within the scope of the Independence Standards in this Part,
the Firm shall take into account the length of time45 an individual has served the
Sustainability Assurance Client as a Key Sustainability Assurance Leader or Key
Audit Partner before the Firm begins to undertake Sustainability Assurance
Engagements within the scope of the Independence Standards in this Part in
determining the timing of the rotation. If the individual has served the Sustainability
Assurance Client as a Key Sustainability Assurance Leader or Key Audit Partner
for a period of five cumulative years or less when the Firm first undertakes a
Sustainability Assurance Engagement within the scope of the Independence
Standards in this Part, the number of years the individual may continue to serve
the client in the capacity of a Key Sustainability Assurance Leader before rotating
off the Sustainability Assurance Engagement is seven years less the number of
years already served. As an exception to paragraph R5540.7, if the individual has
served the Sustainability Assurance Client as a Key Sustainability Assurance
Leader or Key Audit Partner for a period of six or more cumulative years before the
