Wynn Enertainment ( WYNN) was among the casino companies leading the sector higher a day after it announced a new debt agreement. Wynn shares were up 10.3% to $34.83. Wynn said the agreement waives certain covenants until June 2011 and extends to July 2013 the maturity on $610 million of its remaining $697 million in revolving credit. Wynn in turn agreed to a higher overall rate on the debt. "In general, these are very favorable terms in our view," wrote JPMorgan gaming analyst Joseph Greff. Bernstein Research's Janet Brashear wrote: "The new credit agreement terms give Wynn increased financial flexibility, especially amid what we believe will continue to be a turbulent and potentially unpredictable Las Vegas gaming market." The Las Vegas-based company, which has no debt due this year, is also raising funds to pay off the $375 million left on its 2010 debt, noted analyst Robin Farley of UBS. Elsewhere, Las Vegas Sands ( LVS) was up 10.9% to $5.58. MGM Mirage ( MGM) was higher by 7.4% to $5.80. Melco Crown Entertainment ( MPEL) was trading at $4.40, up 5.7%. Boyd Gaming ( BYD) was up 6.1% to $5.90. Penn National Gaming ( PENN) was up 3% to $27.68. Shares of Ameristar Casinos ( ASCA) were up 1.9% to $13.98.
