A more thorough explanation:

A dead-and-buried company is a business that has dissolved and has no assets left. It is a type of company, which is a corporation or association that carries on a commercial or industrial enterprise. Other types of companies include investment companies, holding companies, and trust companies.

For example, if a small business fails and is unable to pay its debts, it may be forced to dissolve and become a dead-and-buried company. In this case, the business has no assets left to pay its creditors.

Another example of a company is a trust company, which acts as a trustee for people and entities and sometimes operates as a commercial bank. Trust companies are often used to manage assets for wealthy individuals or families.
