Greenmail Payments: Technical Mechanics of Hostile Share Repurchases and Tax Penalties

引导语：Greenmail（绿票收买/绿色邮件）是公司法中一种极具争议的“合法勒索”行为。本文从敌意股份回购、美国税法第 5881 条下的 50% 惩罚性税收以及反绿票条款（Anti-greenmail Provisions）三个维度，深度解析其运行机制，为企业防御恶意掠夺者及大宗股份溢价回购的合规性提供决策参考。

TL;DR: Greenmail refers to a transaction where a company repurchases a substantial block of its own shares from a hostile raider at a significant premium over the market price. In exchange, the raider agrees to drop their takeover bid and sign a Standstill Agreement (promising not to buy more shares for a set period). Technically, it is a "Bribe" paid with company funds to protect the current board's jobs. Due to its unfairness to other shareholders, it is now subject to a 50% Federal Excise Tax (IRC Section 5881) in the US and is explicitly banned by the bylaws of most modern corporations.

📂 Technical Snapshot: Greenmail Framework

🔄 The Greenmail Execution Cycle

The following diagram illustrates the technical process of a "Corporate Ransom" payment to a hostile raider:

🏛️ Technical Framework: IRC Section 5881

To stop the practice of greenmail, the US government introduced Section 5881 of the Internal Revenue Code.

• The Trigger: A 50% excise tax is imposed on any "Gain" realized by a person from the receipt of greenmail.
• The Definition: Payment is greenmail if:
  1. The shareholder held the stock for less than 2 years.
  2. The shareholder threatened a public takeover or tender offer.
  3. The company made a repurchase that was not offered to all shareholders on the same terms.
• The Technical Trap: Raiders often try to structure the payment as a "Consulting Fee" or an "Asset Purchase" to avoid the tax, but the IRS uses a Substance-over-Form doctrine to re-classify these payments as greenmail.

⚙️ The "Standstill" and "No-Compete" Contract

A greenmail payment is useless without a technical Standstill Agreement.

1. Duration: Usually lasts for 5 to 10 years.
2. Scope: The raider is prohibited from buying any shares, participating in any proxy contest, or joining any "Group" that aims to take over the company.
3. Non-Disparagement: The raider is often banned from criticizing the management team or the board in the media. This "Silences" the attacker and prevents them from inspiring other raiders to attack.

🛡️ Anti-Greenmail Provisions in Bylaws

Most sophisticated companies now have Anti-Greenmail Provisions in their corporate charters to protect directors from shareholder lawsuits.

• The Clause: "The Corporation shall not purchase any shares from a 5% shareholder at a price above market value unless such purchase is approved by a majority of the disinterested shareholders."
• The Effect: This effectively takes the "Checkbook" out of the hands of the board. If a raider demands greenmail, the board can honestly say: "We can't pay you because our bylaws won't allow it without a vote we know we will lose."

🔍 Forensic Indicators of a Greenmail Attempt

Analysts and regulators look for these "Red Flags" in corporate filings:

• Sudden "13D" Exit: A raider who was aggressively attacking a company suddenly files a Schedule 13D/A showing they sold their entire stake back to the company "at a negotiated price."
• Unexplained "Legal Settlement" Costs: A massive cash payment in the "Other Expenses" category following the withdrawal of a hostile bid.
• Strategic "Pivot" by Raider: A raider known for hostile attacks suddenly praising the target’s management and moving their capital to a different target.

• Sir James Goldsmith vs. Goodyear (1986): The $90M Profit: Explore how a legendary raider forced the world's largest tire company to buy back its shares and sell off its non-tire businesses.

Frequently Asked Questions (FAQ)

Is Greenmail the same as a Stock Buyback?

No. A Stock Buyback is offered to all shareholders or done on the open market. Greenmail is a private, "Targeted Repurchase" offered only to the hostile raider at a price no one else can get.

Why is it called "Greenmail"?

It is a combination of "Greenbacks" (money) and "Blackmail." It is the practice of using a stock position to extort a premium payment from a board of directors.

Can shareholders sue to stop it?

Yes. They can file a Derivative Lawsuit claiming that the board committed "Corporate Waste" or "Breach of Fiduciary Duty." In many cases, these lawsuits force the board to rescind the payment or pay the company back from their own pockets.

Does the raider always win?

Financially, yes. But they often suffer "Reputational Damage" that makes other companies less likely to negotiate with them in the future. Modern raiders (now called "Activist Investors") often prefer to stay in the stock and force long-term changes rather than taking a quick greenmail check.

Conclusion: The Mandate of Equitable Repurchase

Greenmail is the definitive "Conflict of Interest" in corporate finance. It proves that without strict legal and tax boundaries, company funds can be used to protect management at the expense of the owners. By establishing a rigorous framework of excise taxes, standstill agreements, and anti-greenmail charter provisions, the market ensures that capital is returned to shareholders fairly and transparently. Ultimately, the death of greenmail ensures that a board’s survival depends on its performance, not its ability to pay off its enemies—proving that in the end, the only true source of corporate peace is a verifiable and technical commitment to shareholder value.

Bilingual Summary: Greenmail is a hostile repurchase at a premium. 绿票收买（Greenmail）是一种通过大宗股份回购来换取和平的“合法勒索”手段。敌意收购者（掠夺者）先买入公司大量股份并威胁发起收购，董事会为了保住职位，同意以远高于市价的价格（溢价）向该掠夺者回购其持有的股份。作为交换，掠夺者签署“不扩持协议”并撤回收购。这种行为因损害其他股东利益，在美国面临 50% 的惩罚性税收（IRC 5881），并被大多数现代公司的章程明确禁止。
