What is the specific meaning of "net capital management constraint" of trust companies? Can you give me an example?

Trust companies need to set aside risk reserves when doing projects. For example, if it is a 65.438 billion+0 billion real estate project, and the risk coefficient of this real estate project is 0.3%, then it is necessary to set aside 3 million net venture capital. It is required that the net risk capital of the trust company shall not be lower than the net risk capital at any time. Suppose the company's net venture capital is 2.5 billion yuan, and the net venture capital of all projects can't add up. More than 2.5 billion, this is to prevent trust companies from using limited capital for excessive investment leverage, which is equivalent to limiting their business scale according to their capital strength.
