(36)Taking into account the long-term retirement nature of the PEPP and the administrative burden involved, PEPP providers and PEPP distributors should provide clear, easy to understand, and adequate information to prospective PEPP savers and PEPP beneficiaries to support their decision-making about their retirement. For the same reason, PEPP providers and PEPP distributors should equally ensure a high level of transparency throughout the various phases of a PEPP including the pre-contractual stage, the conclusion of the contract, the accumulation phase (including pre-retirement) and the decumulation phase. In particular, information concerning accrued retirement entitlements, projected levels of PEPP retirement benefits, risks and guarantees, the integration of ESG factors and costs should be given. Where projected levels of PEPP retirement benefits are based on economic scenarios, that information should also include a best-estimate scenario and an unfavourable scenario, which should be extreme but realistic.
