take under
n.— «The rumor turned out to be wrong, as rumors often do. But this one even had an exact price: Lehman would be sold for $15 a share, traders buzzed all afternoon, in what would amount to a “take under”—Wall Street parlance for when a company sells itself for less than its market value.» —“Psst! Hear the Rumor of the Day?” by Andrew Ross Sorkin New York Times July 8, 2008. (source: Double-Tongued Dictionary)
