1. Change in circumstances

A "change in circumstances" includes any change that results in the addition of information relevant to a person's status or otherwise conflicts with such person's status. In addition, a change in circumstances includes any change or addition of information to the Account Holder's account (including the addition, substitution, or other change of an Account Holder) or any change or addition of information to any account associated with such account (applying the account aggregation rules described in subparagraphs C(1) through (3) of Section VII of Annex I) if such change or addition of information affects the status of the Account Holder.

If a Reporting Financial Institution has relied on the residence address test described in subparagraph B(1) of Section III of Annex I and there is a change in circumstances that causes the Reporting Financial Institution to know or have reason to know that the original Documentary Evidence (or other equivalent documentation) is incorrect or unreli­ able, the Reporting Financial Institution must, by the later of the last day of the relevant calendar year or other appro­ priate reporting period, or 90 calendar days following the notice or discovery of such change in circumstances, obtain a self-certification and new Documentary Evidence to establish the residence(s) for tax purposes of the Account Holder. If the Reporting Financial Institution cannot obtain the self-certification and new Documentary Evidence by such date, the Reporting Financial Institution must apply the electronic record search procedure described in subparagraphs B(2) through (6) of Section III of Annex I.
