What is "solvv"

SolvV is short for Solvabilitätsverordnung which means solvability directive in German, i.e. the delegated legislation of §§ 10 ff of the Kreditwesengesetz and in effect since 2006. The long name in German is Verordnung über die angemessene Eigenmittelausstattung von Instituten, Institutsgruppen und Finanzholding-Gruppen, literally "directive on the appropriate setting of equity for (financial) institutes, groups of institutes and financial holding groups". There is an analogous directive with the same name in Austria.
