malus
n.—Gloss: A penalty for poor performance, the opposite of a bonus. «A report by Frankfurt-based Center for Financial Studies has coined a new word—malus. Malus is Latin for “bad” while bonus means “good.” It says if executives can win bonuses for a superior performance, they also need to be exposed to penalties such as salary cuts for presiding over failures, which can have ramifications for financial stability.» —“Financial crisis will axe 20 million jobs” Indian Express (New Delhi, India) Oct. 21, 2008.
