80/100Rarity: very rare
TechnicalRegister
A takeover defence in which the target sells or options its most prized assets to deter a hostile bidder.
Facing the raider, the board floated a crown-jewel lock-up on the flagship division, betting the suitor only ever wanted that unit.
Rarity runs from 0 (a word everyone knows) to 100 (almost never seen outside specialist or literary writing). Level is the word's real difficulty on the CEFR scale, from A1 to C2.
