A business can be structured using an operating company and a holding company together, where the operating company runs the business and the holding company oversees it. Using this structure, an operating company, or opco, is a public facing corporation that carries out and is liable for all active business. Often, an opco is a standard business that sells a product or service. By contrast, a holding company, or holdco, is a behind-the-scenes corporation that holds usually 100% of the shares in one or more opcos. Rather than carrying out active business, the holdco allows for an opco’s shareholder(s) to make the most of the opco’s dividends, taxes, etc. Think of a holdco as an administrative tool that supports an opco by giving its structure an extra layer. Note that both opcos and holdcos are incorporated.
