Should a company's zakat be calculated before or after the distribution of profits?

Zakat (definition) becomes due on companies upon the completion of a hawl (one lunar year). It is calculated based on the nisab (definition) (minimum threshold) regardless of whether profits are made or not, and no new hawl begins for the profits. The wealth of partners is not combined to complete the nisab. Each partner pays Zakat on their share if it reaches the nisab, even if by combining it with other Zakat-eligible wealth they own.
