Latin America is facing the problems of ageing and the results of social security schemes (pensions) based on pay-as-you go basis or individual capitalization. In both cases, respectively problems are arising, due to the negative gap between incomes as contributions and expenditures, and on low replacement rates. My experience in actuarial valuations and pension reforms indicates that there is a need of sound actuarial participation, with elevated level of professionalism and applying ISAP-1 and ISAP-2, with high abilities in communication. Also, negotiation and transparency are important subjects. Different participants, like social and economic sectors, implies a complicate area to achieve an agreement. What actuaries can do? We must work in teams, without losing our identity and professionalism, combining quantitative activity with soft abilities, to obtain consensus and at least, to get a reasonable medium term interim solution. The paper will show guidelines to perform an appropriate work in this social conflictive area of actuarial practice.

Labor markets, typically subject to ageing population, today are sensible also to the implications still deriving from the recent Covid-19 pandemic. In such scenario, it is increasingly challenging to ensure that social security systems continue to meet their objectives of adequacy of benefits and sustainability constraints. Financial sustainability and adequacy of benefits are two sides of the same matter and must be jointly considered. In the medium to long term, unsustainable pension systems may not be able to guarantee enough level of the benefits. At the same time, the financial sustainability, pursued through a compression of the benefits, may be not socially feasible. In this work the so-called Pension Wealth indicator (PW) is used to measure the adequacy on benefits provided by social security schemes, in the light of the after effects of the pandemic with a focus on the Italian workers’ protection system. PW is the ratio between the actual value, on pensionable age, of all the pension payments that are expected to be paid (generally for the entire life) and the last salary received. PW is highly related to the future mortality trends and its study may give useful information on how to face the recent shocks on expectancy of life. PW can be thought as the lump-sum needed to buy an annuity giving the same cash flow as that of a generic annuity. The PW is generally referred to old age pensioners, but the aim of this study is to present a redefinition of PW with reference to specific vulnerable workers: the Italian injured worker broken down by accidents and occupational diseases and by impairment level.

What are the levers of attractiveness of long-term care insurance that we need to act on? In France, the creation of a 5th branch of Social Security dedicated to autonomy is a significant step forward. However public finances will not be able to assume the costs linked to the loss of autonomy of all our fellow citizens and families will not have all the financial resources to absorb the remaining expenses of their elders. These issues undeniably argue for the use of insurance solutions to support the public authorities. It is therefore essential that we, as actuaries, continue to work on making our long-term care products more desirable and durable. This workshop will be an opportunity to present an overview of the long-term care insurance market, highlighting in particular the issues, practices, market projects and prospects specific to this risk.

Taxation, regional regulations and certain exogenous factors might affect a plan sponsor’s interpretation, approaches and success in achieving sustainability of their defined benefit plan. Rules regarding the design, funding and taxation of most defined benefit plans are regional, typically by country, or perhaps by state or province. The rules usually focus on encouraging sponsorship and participation, and/or ensuring sufficient funding. There are often other goals, such as limiting tax deductions or preventing discrimination by age, gender, pay-level, etc. While they may be well-intended, the rules can often constrain a sponsor’s ability to implement effective, long-term policies that seek to optimize plan sustainability. Layered on top of the general rules are often tax laws that can influence or reward sponsor and participant actions. These incentives, or sometimes disincentives, can lead to sponsor and participant choices that might be counter to a plan’s optimal path to sustainability. In addition, an organization’s approach to plan sustainability could be constrained by exogenous factors, such as: prioritization of short-term financial results diverting from long-term funding; demographic aging if benefit costs (intentionally or unintentionally) rely on intergenerational cross-subsidies; long-term global trends affecting capital market returns, long-term return expectations or inflation experience; and mortality improvements. The paper will examine how these constraints can affect a plan’s sustainability, how a sponsoring organization might better achieve sustainability if unconstrained, and a case study of the United Nations Joint Staff Pension Fund, which operates free of certain constraints that exist for plans operating under regional regulations and/or taxation regimes.

The South African (SA) government intends reforming its social security system, including retirement. Views vary on how to do this. Proposals often consider international experience, but seldom that of fellow African countries. Africa is experiencing demographic change, especially reduced infant mortality, reduced fertility and increasing old age longevity. SA is advanced relative to other African countries, despite high unemployment levels. SA’s informal sector is large relative to developed countries, but smaller than Africa’s norm. African countries have tried different reform approaches. SA’s non-contributory pensions are advanced relative to Africa’s norm. Most African countries have mandatory national schemes; closest SA equivalent is the Unemployment Insurance Fund (UIF). DB design is the norm. These schemes are experiencing financial strain, leading to increased contributions/reduced benefits. SA’s well established occupational retirement funds have experienced significant reforms recently. Occupational fund coverage is not mandatory but is high relative to other African countries, even those with compulsory coverage. SA is new to introducing informal sector contributory pensions. Other countries have tried various approaches without finding perfect solutions. Maximising coverage requires all pension types. Pension reform is iterative, phasing-in change is best. Government should start with incremental improvements. Sequencing of reforms is important, changes at each pension provision level influence what can/should be done at subsequent levels. SA should move towards cost-effective universalisation of non-contributory pensions. African countries’ experience should be considered when targeting informal sector coverage. Compulsory formal sector contributory pensions are recommended. Consider expanding the UIF to cover retirement instead of creating a new scheme.
