Scalars are a central part of efforts to develop capital adequacy measures for financial groups that operate businesses in more than one country and/or more than one industry. They provide a way to effectively “translate” capital requirements that are not strictly comparable and vary across jurisdictions into a common regulatory framework. In this session, we will discuss the American Academy of Actuaries’ recently released research paper on scalar methodologies to aggregate capital requirements across regulatory frameworks. The Academy’s research describes four families of scalar methodology and assesses them based on four independent, general criteria. During the session, we will review several of the major results presented.
