Casino operator Las Vegas Sands ( LVS) said Wednesday it hopes to raise $3 billion to $4 billion through various fundraising options, including a possible initial public offering of its Macau assets in Hong Kong, Reuters and other publications report.

Chairman Sheldon Adelson told Reuters in an interview that the planned sale of the company's Macau retail operations had been put on hold because of uncertain market conditions.

"We are looking at a Hong Kong Stock Exchange listing among five or six options," Adelson told Reuters.

The company will decide this month whether to sell shares in Hong Kong, Bloomberg reports, quoting Chief Operating Officer Michael Leven as saying it "will have to be $2 billion, $2 billion plus area to make it work for us."

Meanwhile, Adelson said the opening of the company's $5.5 billion Singapore casino and resort will be delayed until early next year because of problems sourcing construction materials, the Associated Press reports.

The Marina Bay Sands, one of two casinos being built in Singapore, is now expected to open in January or February, Adelson said Wednesday, instead of December as the company predicted earlier this year.

The Singapore casino was one of the few projects Sands continued to work on after the company was hit with a massive cash crunch, caused by the credit crisis and tumbling revenue at its Las Vegas properties. Its funding crisis forced it to suspend work on a Macau project last November and lay off as many as 11,000 workers.

Adelson said the company's Venetian and Palazzo casinos in Las Vegas, where it last week laid off 194 workers, have had better-than-expected business so far this summer but didn't provide figures, AP reports.

"Our results in June were significantly higher than what we expected," Adelson said. "Our projections for the summer, while slower than previous summers, are also somewhat ahead, and we're adjusting our internal forecasts almost every week."
