The company said on Wednesday it had sold a $1 billion 10-year bond with a coupon of 4.625 percent, and a $1.6 billion senior secured credit facility to finance the Las Vegas project.

Orders from investors reached $3.8 billion, according to a banker on the bond deal, indicating strong demand, including from U.S. investors that focus on investment-grade issues.

S&P gave the bond a BBB+ rating, a rare investment-grade rating in the sector, bankers said.

One banker who worked on the deal said it was unusual to get an investment-grade rating for a project still in development which has no cashflow and carries construction risk.

The resort will also feature more than 300,000 square feet of meeting and conference space, the presentation showed.

Barclays, Citigroup and JPMorgan were joint global coordinators for the bond issue.
