A more thorough explanation:

Omnium is a word used in mercantile law and in Great Britain to describe the total amount or value of items in a combined fund or stock. It refers to the sum of all the items in a particular collection or group.

• The omnium of the company's assets was estimated to be around $10 million.
• The omnium of the estate included various properties, stocks, and bonds.

These examples illustrate how the term omnium is used to describe the total value of a collection of items. In the first example, the omnium refers to the total value of the company's assets. In the second example, the omnium refers to the total value of the estate's properties, stocks, and bonds.
