Abstract
The class of fixed-fraction rules for sharing sequentially triggered losses has been axiomatized using a set of axioms that include continuity. In this note, we show that continuity is redundant because it is implied by the other axioms. This allows for a more parsimonious characterization and thus reducing complexity.
