Interests in funds managed by KKR & Co., Madison Dearborn LLC and Terra Firma Capital Partners Ltd. all are being offered at discounts of at least 50 percent, according to people familiar with the sales

(emphasis mine) Illiquid: You have assets, but no buyers, so those assets are worthless, or near worthless. This is what Greenspan's "financial innovation" have gotten us.
