The write-down of the principal amount shall apply on a pro rata basis to all holders of Additional Tier 1 instruments that include a similar write-down mechanism and an identical trigger level.

For the write-down to be considered temporary, all of the following conditions shall be met:

1. (a)

   any distributions payable after a write-down shall be based on the reduced amount of the principal;

2. (b)

   write-ups shall be based on profits after the institution has taken a formal decision confirming the final profits;

3. (c)

   any write-up of the instrument or payment of coupons on the reduced amount of the principal shall be operated at the full discretion of the institution subject to the constraints arising from points (d) to (f) and there shall be no obligation for the institution to operate or accelerate a write-up under specific circumstances;

4. (d)

   a write-up shall be operated on a pro rata basis among similar Additional Tier 1 instruments that have been subject to a write-down;

5. (e)

   the maximum amount to be attributed to the sum of the write-up of the instrument together with the payment of coupons on the reduced amount of the principal shall be equal to the profit of the institution multiplied by the amount obtained by dividing the amount determined in point (1) by the amount determined in point (2):

   1. (1)

      the sum of the nominal amount of all Additional Tier 1 instruments of the institution before write-down that have been subject to a write-down;

   2. (2)

      the total Tier 1 capital of the institution.

6. (f)

   the sum of any write-up amounts and payments of coupons on the reduced amount of the principal shall be treated as a payment that results in a reduction of Common Equity Tier 1 and shall be subject, together with other distributions on Common Equity Tier 1 instruments, to the restrictions relating to the Maximum Distributable Amount as referred to in Directive 2013/36/EU UK law which implemented Article 141(2) of Directive 2013/36/EU.

For the purposes of point (e) of paragraph 2, the calculation shall be made at the moment when the write-up is operated.

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.
