(a) 15 consecutive business days starting from the first business day of the testing of the impact of the extension or change;
(b) until such day where a daily calculation of either one of the ratios referred to in paragraphs 2 and 3 results in an impact equal or greater than the percentages referred to in either paragraph (1)(c)(i) or paragraph (1)(c)(ii), respectively.
Article 7b 
Extensions and changes to the IMA, which are not material but are to be notified to competent authorities according to the second subparagraph of Article 363(3) of Regulation (EU) No 575/2013, shall be notified in the following manner:

((a)) extensions and changes falling under Annex III, Part I, Section 2, and Part II, Section 2, shall be notified to competent authorities two weeks before their planned implementation;
((b)) all other extensions and changes shall be notified to the competent authorities after implementation at least on an annual basis.'
5.. Article 8(1) is replaced by the following:
'
1. For extensions and changes to the IRB approach, or to the AMA or to the IMA classified as requiring competent authorities' approval, institutions shall submit, together with the application, the following documentation:
(a) description of the extension or change, its rationale and objective;
