Adelson, 75, loaned Las Vegas Sands $475 million on Oct. 1 through convertible senior notes to help the company meet liquidity requirements and avoid the triggering of a $5 billion loan covenant. "The company will announce further details of the program in the very near future," according to the statement. Thomas Weisel Partners' Jake Fuller said the company's announcement -- while short on details -- may be viewed as a very modest positive. "While there is a very real balance sheet risk here, we argue that Las Vegas Sands will be able to dodge a crunch with an infusion from Mr. Adelson, a covenant amendment, securing of project financing or delay of Cotai projects," he wrote. Jefferies & Co. gaming analyst Larry Klatzkin believes Adelson will invest a total of at least $1 billion into Las Vegas Sands by the end of the year.
