The assets of the company at the time of its foundation. Patrimony is the term often used in countries of eastern Europe.

From the Britannica:
Business associations have three distinct characteristics: (1) they have more than one member (at least when they are formed); (2) they have assets that are legally distinct from the private assets of the members; and (3) they have a formal system of management, which may or may not include members of the association... The second feature, the possession of distinct assets (or a distinct **patrimony**), is required for two purposes: (1) to delimit the assets to which creditors of the association can resort to satisfy their claims...

The initial *patrimony* of the Foundation can be increased... Initial capital or *patrimony*, expressed in legal currency, no less than the equivalent of ten thousand US dollar
