The crown-jewel defense is a takeover defense in which a target disposes of — or grants a friendly party an option to buy — its most valuable assets (its "crown jewels"), so that the company becomes less attractive to the hostile acquirer. The logic is blunt: if the raider wants the company for a particular prize asset, putting that asset out of reach removes the motive for the bid.
How it works
When the "crown jewels" are the real target of a hostile bid — a coveted division, brand, technology, or subsidiary — the board can:
- Sell the prize asset to a friendly third party;
- Spin it off to shareholders; or, most commonly,
- Grant a friendly party an option (a "lock-up") to buy the asset at a favorable price, triggered if the hostile bid succeeds.
With the jewels gone or spoken for, the remaining company holds little appeal for the raider, who may withdraw.
Why it is a "scorched-earth" tactic
The crown-jewel defense is classed among "scorched-earth" defenses because it can damage the company to save it from the bidder. Selling off the best assets — possibly in a rushed, sub-optimal transaction — can leave the surviving company weaker and less valuable, harming the very shareholders the board is supposed to serve. It is a defense of last resort, used when a board is determined to defeat a specific acquirer and has run out of friendlier options.
Legal constraints
Precisely because it can destroy value, the crown-jewel defense draws heightened judicial scrutiny, especially in Delaware. A board's defensive actions are tested against its fiduciary duties: under the Unocal standard, a defense must be a reasonable, proportionate response to a genuine threat — and a crown-jewel lock-up that forecloses a better deal for shareholders or is used simply to entrench management can be struck down. The landmark Revlon case arose partly from a crown-jewel lock-up the court found improperly ended an active auction; once a company is "for sale," the board's duty shifts to maximizing price, and a defense that sacrifices value to favor one bidder is vulnerable. As a result, crown-jewel defenses are used cautiously and are far less common than structural defenses like the poison pill.
Relation to other defenses
The crown-jewel defense often works alongside a white knight or white squire — the friendly party that receives the asset or option — and stands in contrast to the poison pill (which dilutes the raider rather than disposing of assets). It is the most self-harming of the common defenses, which is exactly why courts and boards treat it with caution.
