5. With respect to the United Kingdom's liability for the pension rights and rights to other employment-related benefits referred to in paragraph 2 as regards pensions of the Members and EU high-level public office holders covered by Council Regulation 422/67/EEC, 5/67/Euratom(1), Decision 2005/684/EC, Euratom of the European Parliament(2) and Council Regulation (EU) 2016/300(3), the United Kingdom shall contribute to the liabilities as they are recorded in the consolidated accounts of the Union for the financial year 2020 in 10 instalments starting on 31 October 2021.

6. With respect to the United Kingdom's liability for the pension rights and rights to other employment-related benefits referred to in paragraph 2 as regards pensions of officials of the Union established in accordance with Articles 77 to 84 of the Staff Regulations of Officials of the European Union and as regards the pensions of temporary staff, contract staff and parliamentary assistants established in accordance with Articles 33 to 40, Articles 101 to 114 and Article 135, respectively, of the Conditions of Employment of Other Servants of the European Union, the United Kingdom shall contribute annually to the net payments made from the Union budget to each beneficiary and to the related contribution of the Union budget to the JSIS for each beneficiary or person who benefits through a beneficiary. The payments of that contribution shall start on 30 June 2022.

For the pensions referred to in the first subparagraph, the payment by the United Kingdom shall be the sum of the net payments made by the Union budget in the preceding year for each beneficiary, multiplied by the United Kingdom's share and by a percentage that is specific to each beneficiary ("specific percentage"). The specific percentage shall be as follows:

(a) for a beneficiary receiving pension on 1 January 2021, the specific percentage shall be 100 %;

(b) for any other beneficiary of a pension, the specific percentage shall be calculated as the ratio between the pension rights acquired in accordance with the Staff Regulations of Officials of the European Union and in particular in Annex VIII thereto on or before 31 December 2020, including pension rights transferred in at that date, and the acquired pension rights at the date of retirement or death if earlier, or at the date the person leaves the scheme;

(c) for the purposes of the contribution of the budget to the JSIS, the specific percentage shall be calculated as the ratio between the number of years during which the beneficiary contributed to the pension scheme until 31 December 2020 and the total number of years at retirement during which the beneficiary, or the person covered by the Staff Regulations of Officials of the European Union who is the basis for the rights under the JSIS, contributed to the pension scheme.

For a beneficiary of a survivor's pension or an orphan's pension established in accordance with the Staff Regulations of Officials of the European Union, the calculation shall be made on the basis of the career of the person covered by those Staff Regulations which is the basis for the survivor's pension or the orphan's pension.

As long as the liability in relation to this paragraph is not extinguished, in any given year ("year N") the United Kingdom may send the Union before 1 March of year N a request to pay the outstanding liability at 31 December of year N. The Union shall establish the amount of the outstanding liability in relation to the pension and JSIS post-employment benefits, using the same methodology as used in point (d) of paragraph 4. If the United Kingdom agrees, it shall pay that amount in five instalments, with the first payment taking place in the year N+1. The United Kingdom shall also cover its liability for the year N through the procedure set out in this paragraph. After that payment has been completed, and provided that the payments referred to in paragraph 5 have been completed, the remaining obligations under this Article shall be extinguished. The Committee on the financial provisions referred to in point (f) of Article 165(1) and the Joint Committee shall be informed of this situation.
