Solvency II came into force on 1 January 2016 and included a transitional measure on technical provisions (“TMTP”) designed to help smooth in the capital impact of Solvency II over a 16-year period. The working party’s view is that the main intention of the TMTP is to mitigate the impact of the introduction of the risk margin, which significantly increases the technical provisions of firms, relative to their Solvency I Pillar 2 liabilities.The majority of firms who hold a TMTP have now had at least one recalculation approved by the Prudential Regulation Authority (PRA); or are in the process of applying for a recalculation. Despite this large number of approved recalculations, there remains significant uncertainty in the industry around the approach and triggers for recalculation.This paper considers aspects of TMTP recalculation for regulated UK life firms, for example practicalities of the calculation, asset and liability considerations, and communications/announcements.In this paper, we outline the need for pragmatism when considering the approach to recalculation of a measure originally intended to serve as the bridge between two regimes. We call for an allowance for doing what is sensible in a principles-based regime balancing what might be more theoretically correct with what is practical and possible to support effective management of the business.
Approaches to determining the influence of individual measurements on the precision ofcrystallographic least squares parameters have been known for a long while [1,2,3,4,5].Situations in which the precision of a single parameter (or linear combination ofparameters) is critical can include: determination of novel bond lengths; refinement ofsite occupancies in mixed metal or mixed oxidation state systems; determination of thefraction of excited state molecules in a time-resolved pump-probe experiment.Such calculations are easily applicable to pointdetector instruments, where individualinfluential reflections could be remeasured one-by-one. However, on a modern areadetector instrument many reflections are measured on one frame and therefore someconsideration of the appropriate strategy of reciprocal space scans is permitted to allowa more efficient use of the instrument. We present an analysis of diffractometer strategy selection to prioritize scans whichgive the best improvement in specific least-squares parameters.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
