Introduction
With a view to alleviating the impact of the COVID-19 pandemic on provisioning levels of financial institutions, the Bank of Mauritius is introducing transitional arrangements for regulatory capital treatment of IFRS 9 provisions for expected credit losses. These transitional arrangements are in line with guidance issued by the Basel Committee for Banking Supervision on “Regulatory treatment of accounting provisions – interim approach and transitional arrangements” of March 2017 and on “Measures to reflect the impact of Covid-19” of April 2020. These transitional arrangements apply to all banks and non-bank deposit taking institutions licensed by the Bank of Mauritius, hereinafter referred to as financial institutions, and shall come into effect on 13 January 2021.

Transitional arrangements for regulatory capital treatment of IFRS 9 provisions for expected credit losses (ECL)

1. A financial institution shall inform the Bank on whether it is electing to apply the transitional
   arrangements no later than 15 February 2021. Financial institutions electing to apply the transitional arrangements shall implement the requirements set out in this Guidance.

2. During the transitional period, a financial institution may elect to opt out of the transitional
   arrangements but may not elect to apply the transitional arrangements again after opting out of it. A financial institution opting out of the transitional arrangements shall immediately inform the Bank of its decision on same.

3. A financial institution electing to apply the transitional arrangements, shall refrain from paying
   dividends and making other transfers from profit until the end of the transitional period or until it opts out of the transitional arrangements.

4. A financial institution shall add back a proportion of Stage 1 and Stage 2 provisions under
   IFRS 9 to its Tier 1 Capital. Banks shall add the provisions back to Common Equity Tier 1 (CET1) Capital and non-bank deposit taking institutions (NBDTIs) shall add the provisions back to Tier 1 Core Capital.

5. The amount of Stage 1 and Stage 2 provisions to be added back to CET1 Capital or Tier 1 Core
   Capital shall be calculated as follows:
   𝐴𝑑𝑑 𝑏𝑎𝑐𝑘 = 𝑚𝑎𝑥[0, (𝑃𝑐𝑢𝑟𝑟𝑒𝑛𝑡 − 𝑃𝑏𝑎𝑠𝑒𝑙𝑖𝑛𝑒) × 𝑓] where 𝐴𝑑𝑑 𝑏𝑎𝑐𝑘 is the amount of Stage 1 and Stage 2 provision to be added back to CET1 Capital or Tier 1 Core Capital 𝑃𝑐𝑢𝑟𝑟𝑒𝑛𝑡 is the amount of Stage 1 and Stage 2 provision at end of reporting period 𝑃𝑏𝑎𝑠𝑒𝑙𝑖𝑛𝑒 is the amount of Stage 1 and Stage 2 provision as at 31 December 2019 𝑓 is the transition factor as stipulated in paragraph 6

6. The transition factor shall be as follows:
   𝑓
   From 1 January 2021 to 31 December 2021 100%
   From 1 January 2022 to 31 December 2022 75%
   From 1 January 2023 to 31 December 2023 50%
   From 1 January 2024 to 31 December 2024 25%
   From 1 January 2025 onwards 0

7. Examples of calculation of the transitional arrangements are provided in Annex 1.

8. Stage 1 and Stage 2 provisions eligible for inclusion under Tier 2 Capital:
   Stage 1 and Stage 2 provisions which have been added back to CET1 Capital or Tier 1 Core Capital should not be included under Tier 2 Capital. Only the amount of Stage 1 and Stage 2 provisions not added back to CET1 Capital or Tier 1 Core Capital may be included in Tier 2 Capital subject to section 16(d) of the Guideline on Scope of Application of Basel III and Eligible Capital or section 9(b) of the Guidelines on Capital Adequacy Ratio for Non-Bank Deposit Taking Institutions.

9. A financial institution shall disclose publicly, at least in its audited annual financial statements,
   whether it is applying the transitional arrangements.

10. Financial institutions shall report to the Bank the amount of provisions added back to their
    regulatory capital, as well as their regulatory capital without applying the transitional arrangements. The reports shall be submitted on a quarterly basis, together with the Returns on Statement of Capital Adequacy Calculation for banks and with the Returns on Capital adequacy calculation for NBDTIs, as per reporting template at Annex 2 for banks and Annex 3 for NBDTIs.
