Tunnelling

Tunnelling is a deceptive and often illegal practice where a company's controlling shareholders or senior managers divert corporate assets or profits for their personal gain. Think of it as insiders secretly digging a tunnel to siphon away the company's treasures, leaving the other investors, known as minority shareholders, with a devalued and plundered business. This isn't just about taking cash from the register; it's a sophisticated form of theft that can be disguised through complex corporate manoeuvres. These actions directly harm minority shareholders by transferring wealth that rightfully belongs to all owners of the company into the pockets of a select few. Tunnelling undermines the very foundation of fair markets and trust, making it a critical risk for investors to understand and identify.

How Does Tunnelling Work?

Insiders have a playbook of tricks they can use to tunnel resources out of a company. While the schemes can be complex, they usually fall into a few common categories.

Asset and Transaction Games

This is the most direct method. Insiders use their influence to orchestrate deals that benefit themselves at the company's expense.

Unfavourable Financial Agreements

Money itself can be tunnelled through questionable financial arrangements.

Why Should a Value Investor Care?

For a value investor, tunnelling isn't just a minor issue; it's a deal-breaker. The entire philosophy of value investing rests on buying a business for less than its real, underlying worth, or intrinsic value. Tunnelling directly attacks and destroys that intrinsic value. The cash, assets, and profits siphoned off by insiders are value that will never reach you as a minority shareholder. It’s like buying a share in a treasure chest, only to discover the captain has a secret trapdoor to empty it before you get your cut. This practice is the ultimate sign of poor corporate governance and untrustworthy management. Legendary investor Warren Buffett has famously stated he only invests in businesses run by able and honest people. Tunnelling is a five-alarm fire signalling that management is not working for all shareholders. No matter how cheap a stock seems, if the people in charge are actively stealing from the company, you're not getting a bargain—you're buying a ticket on a sinking ship.

Red Flags to Watch For

Spotting tunnelling requires a bit of detective work. While you might not find a signed confession, you can look for clues in a company's reports and behaviour.
