What it means
In a typical group structure, a parent or holding company (HoldCo) owns shares in several subsidiaries. The OpCo carries out the trading activity, signs contracts with customers and suppliers, and employs most of the workforce.
Other entities may own the brand, the property or the intellectual property and charge the OpCo for using them. Separating the operating company has several benefits.
It can limit legal risk, since a claim against the trading business may not reach assets held elsewhere. It also makes it easier to sell or finance one part of the group without involving the rest.
The OpCo's accounts show the true performance of the trading business. Its revenue, costs and profit reflect the daily operations, and lenders often assess it on cash flow and ability to meet payments.
Charges to other group companies, such as rent, royalties or management fees, can affect its profit and must be set at fair levels. There are nuances.
Creditors may look through the structure if a group has mixed funds or acted unfairly, and guarantees given by the parent can link the companies back together. Tax authorities also check that charges between group members are priced fairly, as if the companies were unrelated.
For readers of financial statements, the key point is to find out which entity actually earns the profit and holds the liabilities. A group with a healthy consolidated result can contain an OpCo with heavy debts or thin margins.
Looking at each entity separately gives a more reliable picture of risk. Accounting for the group adds another layer.
When the companies are consolidated, transactions between the OpCo and its sister companies are removed so that the group does not count its own rent or fees as outside income. The OpCo's own statutory accounts still show those charges, so finance teams keep a clear schedule of intercompany balances to reconcile the two views.
In practice
Real-world examples.
Example
A restaurant group sets up a separate operating company for each country. Each OpCo hires staff and pays suppliers, while the brand is held by a different company. If one country fails, the others are protected.
Example
A private equity firm buys a manufacturing group and puts the debt in a holding company above the OpCo. The OpCo continues to run the factories, and its cash flow pays dividends upward to service the debt. The structure gives the lender a claim on the shares and not the plant.
Example
A telecom business separates its network towers from its operating company so it can sell the towers for $300 million. The OpCo then pays rent to use them. Management uses the cash to reduce debt and invest in new services.
Formula
Calculation
Operating margin = operating profit / revenue
Suppose an OpCo has annual revenue of $20,000,000, operating costs of $15,000,000 and pays $1,000,000 in rent and fees to other group companies.
Operating profit = 20,000,000 - 15,000,000 - 1,000,000 = $4,000,000.
Operating margin = 4,000,000 / 20,000,000 = 0.20, or 20%.
If the rent and fees rose to $2,000,000, operating profit would fall to $3,000,000, and the margin would be 3,000,000 / 20,000,000 = 15%.Case study
Seen in the real world.
Crestline Hospitality is an illustrative, fictional group that owns a chain of 20 hotels. It created a separate operating company, called Crestline Operations, to employ staff and run the hotels, while another company owned the buildings.
When a dispute with a supplier led to a legal claim of $2 million, the claim could only be made against the OpCo. The property company, which held the buildings worth $150 million, was not directly affected, although the lender asked for assurances.
The chief financial officer used the episode to review the group guarantees and insurance. She found that the parent had guaranteed several OpCo leases, which weakened the protection. The illustrative lesson is that a separate OpCo only protects the group if the legal and financial links between the companies are managed carefully.
Watch out
Common mistakes.
- Assuming that a separate OpCo means the group can never be affected by its losses, when guarantees and shared funding can pass the risk upwards.
- Setting rent or management charges at unrealistic levels, which distorts the OpCo's results and may draw tax scrutiny.
- Looking only at group accounts, which can hide weak performance in the operating entity.
Questions
People also ask.
What does OpCo mean?
It means operating company, the entity that runs the day-to-day business and employs the staff.
How is an OpCo different from a HoldCo?
A HoldCo owns shares in other companies and usually has no trading activity, while an OpCo carries out the trading itself.
Why do lenders care about the OpCo?
Its cash flow is what ultimately pays the group's debts, so they assess its profitability and stability.
