Madam, Sir,
I. Objectives
This circular relates to Articles 154 to 160 of the Act.
It aims to provide additional specifications on the treatment of risk mitigation techniques in the calculation of the Solvency Capital Requirement for undertakings of all types and sizes within the framework of Solvency II. It concerns undertakings and professionals responsible for the treatment of risk mitigation techniques in the calculation of the Solvency Capital Requirement using the standard formula.
II. Definitions
In the absence of a definition in this circular, terms have the meaning defined in the legislative and regulatory acts referenced therein.
III. Additional Information
This circular is part of the harmonized implementation of the principles of Directive 2009/138/EC of the European Parliament and of the Council of 25 November 2009 on the taking-up and pursuit of the business of Insurance and Reinsurance (Solvency II), as determined by the guidelines of the European Insurance and Occupational Pensions Authority. Undertakings may consult these guidelines for information at the following address: https://eiopa.europa.eu/publications/eiopa-guidelines.
IV. Entry into Force
This circular applies from 23 March 2016.
V. Guidelines on the Consideration of Basis Risk
Guideline 1 – Risk Mitigation Techniques without Significant Basis Risk Undertakings should consider that a risk mitigation technique does not result in significant basis risk if the following conditions are met:
(a) the exposure covered by the risk mitigation technique is of a nature sufficiently similar to that of the undertaking's risk exposure;

NBB_2016_14 – 25 April 2016 Circular – Page 3/4 (b) the fluctuations in the value of the exposure covered by the risk mitigation technique reflect the fluctuations in the value of the undertaking's risk exposure across a full range of risk scenarios, including scenarios consistent with the confidence level referred to in Article 151, § 3, of the Act. Guideline 2 – Financial Risk Mitigation Techniques: Criteria for Assessing Significant Basis Risk Before taking into account financial risk mitigation techniques in the calculation of the Solvency Capital Requirement using the standard formula, undertakings should evaluate, inter alia:
(a) the relative importance of basis risk compared to the exposure covered by the risk mitigation technique and the undertaking's risk exposure without taking into account other balance sheet items, unless there is a continuous and consistent link between other balance sheet items and the undertaking's risk exposure; (b) the similar nature of the exposures referred to in Guideline 1, taking into account at least the type and terms of the relevant instruments or agreements and the rules governing the markets on which they are listed or which provide data for their valuation; (c) the fluctuations in the value of the exposures across a full range of risk scenarios referred to in Guideline 1, including all scenarios taken into account in the relevant modules or sub-modules of the standard formula, taking into account at least:
(i) the degree of symmetry between the two exposures; (ii) all non-linear dependencies according to the scenario; (iii) any relevant asymmetry in behaviors in risk sub-modules where both upward and downward stress tests are applied; (iv) the diversification levels of each respective exposure; (v) any relevant risks not explicitly taken into account in the standard formula; (vi) the full distribution of payments applicable to the risk mitigation technique. The risk mitigation technique should be considered as resulting in significant basis risk if the aforementioned assessment does not provide sufficient evidence that changes in the value of the exposure covered by the risk mitigation technique reflect all significant fluctuations in the value of the undertaking's risk exposure. If the conditions of a risk mitigation technique specify a cap for maximum protection against losses as a proportion of the initial exposure, undertakings should apply the assessment only to the proportion covered by the risk mitigation technique when determining if basis risk is significant. Guideline 3 – Insurance Risk Mitigation Techniques without Significant Basis Risk Before taking into account an insurance risk mitigation technique in the calculation of the Solvency Capital Requirement using the standard formula, undertakings should establish whether reinsurance contracts and securitization vehicles behave differently from the undertaking's insurance policies across a full range of risk scenarios due to different terms. Undertakings should consider that basis risk resulting from currency asymmetry is significant if the exposure covered by the insurance risk mitigation technique is denominated in a currency other than that of the undertaking's risk exposure, unless the currencies concerned fluctuate within a sufficiently narrow band or a fixed exchange rate is provided for in the reinsurance contract.

Circular – Page 4/4 NBB_2016_14 – 25 April 2016 If there is significant basis risk arising from currency asymmetry, as indicated in the previous paragraph, undertakings should not take into account the risk mitigation technique in the calculation of the Solvency Capital Requirement, unless the provisions of Article 86 of Regulation 2015/35 are applicable. A copy of this circular is sent to the commissioner(s), approved auditor(s) of your undertaking. We ask you to accept, Madam, Sir, the expression of our distinguished sentiments. Jan Smets Governor
