Where the institution has established that the Common Equity Tier 1 ratio has fallen below the level that activates conversion or write-down of the instrument at the level of application of the requirements provided in Title II of Part One of Regulation (EU) No 575/2013, the management body or any other relevant body of the institution shall without delay determine that a trigger event has occurred and there shall be an irrevocable obligation to write-down or convert the instrument.
The amount to be written-down or converted shall be determined as soon as possible and within a maximum period of one month from the time it is determined that the trigger event has occurred pursuant to paragraph 1.
The competent authority may require that the maximum period of one month referred to in paragraph 2 is reduced in cases where it assesses that sufficient certainty on the amount to be converted or written down is established or in cases where it assesses that an immediate conversion or write-down is needed.
Where an independent review of the amount to be written down or converted is required according to the provisions governing the Additional Tier 1 instrument, or where the competent authority requires an independent review for the determination of the amount to be written down or converted, the management body or any other relevant body of the institution shall see that this is done immediately. That independent review shall be completed as soon as possible and shall not create impediments for the institution to write-down or convert the Additional Tier 1 instrument and to meet the requirements of paragraphs 2 and 3.
