Sears Holdings Corp., the struggling one-time U.S. retail stalwart, unveiled two new measures today in a bid to raise cash, one of which again taps into the hedge fund of its billionaire chief executive, the Wall Street Journal reported today. The company said that it would lease seven locations to European fashion retailer Primark, while it also unveiled an offering of debt rights and warrants that could generate as much as $625 million and help fund operations during the holiday-shopping season. Sears said that the hedge fund, run by CEO Edward Lampert, has said that it intends to exercise its portion of the subscription rights in the offering in full, which would result in at least $303 million.
