Adjustments to votes
167 If it appears:
(i) in relation to a particular resolution at a particular meeting; and
(ii) in relation to a particular Approved Depositary,
that the aggregate number of votes cast by or on behalf of the Approved Depositary would without an adjustment exceed that Approved Depositarys Overall Holding at the time specified under Article 60(E) for establishing the entitlement of members of the Company to attend or vote at the meeting then such adjustments shall be made to the aggregate number of votes cast for or against the resolution so that the total number of votes cast by or on behalf of the Approved Depositary does not exceed that Approved Depositarys Overall Holding and the following provisions for making that adjustment shall apply:
(a) such adjustments (which may be adjustments to nil) may be adjustments of all votes which would otherwise be cast by or on behalf of the Approved Depositary or of some of them only and then in the latter event such adjustments may vary as between some votes and others;
(b) if it is willing and able to do so within such time as the chairman of the meeting may prescribe, such adjustments shall be made by the Approved Depositary;
(c) in any other case such adjustments shall be made by the chairman of the meeting on a pro rata basis or in such other manner as may have been prescribed by regulations or procedures made or established by the Directors under Article 85; and
(d) any adjustments made in good faith in accordance with this Article 167 shall be conclusive and binding on all persons interested.
For the avoidance of doubt votes cast by or on behalf of the Approved Depositary shall include votes cast by its Nominee, or by any Appointed Person appointed by that Depositary or its Nominee, or by any proxy of such an Appointed Person.
