The Crown Jewels defense is best defined as:

Compensation is given to executives when changing corporate control

Company A avoids an aggressive takeover by Company B by attempting to buy Company B instead

When threatened by a takeover, a firm will sell off its major assets to be less attractive

Company A is being acquired by Company B, so Company A will buy Company B shares at a price over the market price.

When a company will dilute the stock value by offering it at a discount price, contingent on another firm taking control, making the stock acquisition no longer economically feasible.
