Related Party Transactions

Related party transactions are business deals between a company and people or entities that have a close personal or professional connection to it. Because these relationships can cloud objectivity, businesses must report them transparently to protect outside stakeholders.

What it means

When a business enters into an agreement with someone close to it, such as a company owner, a major shareholder, a director, or a close family member, it is conducting a related party transaction. In standard business dealings, two independent parties negotiate fiercely to get the best possible price.

However, when a business buys services from a CEO's spouse or rents an office building owned by a board member, that natural tension disappears. There is a risk that the deal might not happen on normal market terms, potentially short-changing the business and its other owners.

Regulators and accountants care deeply about these transactions because they create potential conflicts of interest. Without proper oversight, insiders could funnel company money into their own pockets by overpaying for goods or services, or by shifting profits away from minority shareholders.

To prevent this, accounting standards require companies to disclose all significant related party deals in their financial statements. This ensures transparency, allowing investors and lenders to see if transactions were carried out at fair market value.

In daily practice, identifying these transactions requires companies to maintain a clear register of interests, capturing details of directors, key managers, and their connected businesses. Before any contract is signed, the interested party must usually declare their connection and step aside from any voting process.

Auditors will then test these transactions specifically to verify that the prices charged match what an independent third party would pay in the open market.

In practice

Real-world examples.

1

Example

TechStart Ltd rents its main office building from a property company fully owned by the CEO's brother. The company pays 50,000 pounds a year in rent, which must be publicly disclosed.

2

Example

A local catering SME awards its annual office supplies contract worth 12,000 pounds to the operations manager's spouse without checking prices from other suppliers.

3

Example

A manufacturing firm with international operations buys raw materials from a parent company overseas at a fixed rate, requiring careful review for fair market pricing.

Think of it

Imagine you are selling your used car. If you sell it to a stranger, you will haggle to get the highest price. If you sell it to your teenager for five pounds, that is a related party deal, and other family members might rightfully question if the price was fair.

Formula

Calculation

Variance Percentage = ((Related Party Price - Fair Market Price) / Fair Market Price) * 100 Example: If a director charges their company 12,000 pounds for IT services that independent providers offer for 10,000 pounds, the variance is ((12,000 - 10,000) / 10,000) * 100 = 20 percent above market rate, highlighting a potential overpayment.

Case study

Seen in the real world.

BrightRetail plc, a growing fashion chain, needed a new logistics system. The board approved a 250,000 pound contract with SwiftLogistics, a software firm owned entirely by the son of BrightRetail's finance director. The finance director did not vote on the contract, but the company failed to obtain competing quotes from other providers. During the annual audit, the external auditors flagged the deal as an undisclosed related party risk, noting that similar software packages were readily available on the market for 180,000 pounds. As a result, BrightRetail had to issue a revised note in its financial statements detailing the 70,000 pound premium paid to the director's family. The board faced sharp criticism from institutional investors for poor governance and lack of competitive bidding, forcing them to adopt a stricter procurement policy for all future vendor relationships involving staff and family members.

Watch out

Common mistakes.

  • Assuming that transactions with family members do not need to be declared if the amounts involved are small.
  • Failing to keep an up to date register of interests for directors, senior managers, and their close relatives.
  • Forgetting to document how the company determined that a related party price matched fair market rates.

Questions

People also ask.

No, they are completely legal and common in business. They simply require full disclosure and proof that terms are fair.

Who counts as a related party?

This includes parent companies, subsidiaries, major shareholders, directors, key managers, and close family members of these individuals.

Reporting protects investors and lenders by ensuring insiders are not unfairly benefiting at the expense of the wider business.
