Early discussions of proxy modelling were focused on replicating formulae type models and attempting to understand the different methods that have evolved within the industry. Even when replicating formulae type models there are many variations in methodology, so the methods have been split into broad categories upon which to base future investigations.
The categories have been defined in order to identify and differentiate between key methodology differences, for example, the choice between regression and precise interpolation and whether to build a formula from optimised components or optimise the complete formula. Further variations in model design are also being considered, including choice of basis function.
Further investigations will attempt to improve our understanding of the models and their behaviours in order that improvements can potentially be made to the design, calibration and testing of proxy models as used in the insurance sector.

The purpose of this research paper is to explore enterprise risk management lessons which can be learnt from the Covid-19 pandemic in preparation for potential future pandemics as well as other “gray rhino” or “black swan” events. This paper is not intended to be an all-encompassing solution to the issues presented by Covid-19; rather, the content has been provided to help drive discussions regarding how risk management processes may need to evolve in line with the dynamic nature of the underlying risks that they sometimes need to capture.

Big picture thinking, Governance knowledge, Independent mindset, Ambassador potential and Energy and commitment: these are the essential skills sought in a successful NED, according to the Chartered Governance Institute (UK & Ireland).
In parallel, Environmental, Social and Governance (ESG) criteria are increasingly key and used by investors to measure the sustainability and ethical impact of investing in an organisation.
This webinar will cover:
• Some background on the risks of misselling in an ESG context, including the DWS case
• Achieving positive impact is a strong antidote to the risks of greenwashing or ESG misselling, however this risks having a tension with fiduciary responsibilities
• This tension can be resolved with a concept called Universal Ownership
• Under Universal ownership, investors have an appetite to make a loss in order to achieve positive impact, and yet still have no compromise on their fiduciary responsibilities
In the UK, the idea of collective defined contribution (CDC) pension schemes is gaining more attention with the launch of the Royal Mail CDC scheme, the first of its kind in the UK. Our recent research on CDC plans investigates the sources of the putative benefits of CDC schemes: the smoothing of pensions for members. Using an attribution analysis to burrow into the scheme design, the reason for the smoothing of members' pensions is explained and understood.
The IFoA's Infrastructure Working Party, led by Chris Lewin, will present its new introductory guide to infrastructure investment, which will be published on the IFoA web-site prior to the webinar. Those readers whose institutions have already taken the plunge into infrastructure will know that it is a highly complex and diverse field of activity. This guide does not explore all the matters which investors take into account, but it does discuss many of the more important points, including the risks and past returns, benchmarking, and ESG and SDG considerations. Attendees will be invi
Social care reform has long been on the to-do list for successive governments over the last two decades. In February, the government’s proposed reforms to adult social care [including cap on care costs] was published. Against this backdrop of funding promise and rising National Insurance taxation, in this session we will debate the resilience of these new proposals, the impact of future demand for care services and what role for the insurance industry and the important role it has played in long-term care funding in other countries where public-private partnership works.

Mortality and morbidity risk varies by variables such as age, sex and smoking. In traditional actuarial experience analysis, these variables, and certain combinations thereof can be explored. However, with the wealth of data now available it is becoming increasingly challenging to identify the key drivers of experience and account for the interaction between different variables. A univariate approach often compares apples and pears, for example males are more likely to smoke and have larger policies than females. Likewise, variable interactions are missed unless specifically included.
