NEW YORK ( TheStreet) -- Credit woes still loom for casino companies, according to Moody's Investor Services.

While the drastic monthly U.S. gaming revenue declines have started to subside, it's still unclear when trends will improve from current levels and how sustainable any turnaround will be.

"Measures taken by states to address budget deficits, as well as higher financing costs for gaming companies and lower development spending, could have unfavorable implications for the U.S. gaming sector well beyond any recovery," Keith Foley, senior vice president at Moody's, said in a statement.

In other words, gaming companies that refinanced debt during the recession may really have only put a band aid on the wound. Both MGM Resorts ( MGM), Boyd Gaming ( BYD), Isle of Capri Casinos ( ISLE) and privately-held Harrah's Entertainment, have taken steps to refinance debt amid the recession.

MGM's debt is more than 10 times the company's cash flow, Moody's said. Harrah's has more than $22 billion of total debt and a debt-to-cash flow ratio of more than 10 times.

"We do not believe Harrah's will be able to generate enough cash to improve its leverage and credit metrics, especially during a tepid recovery," Foley wrote. "In all likelihood, Harrah's will have to sell assets, issue equity or restructure its debt obligations. Obstacles accompany all of these measures, however, and they likely would result in impairment to debt-holder claims."

Still, Moody's outlook for the sector remains stable, as the rating agency doesn't foresee prolonged severe declined in profits. And there will be some who will remain relatively untouched from these fears.

Moody's says Las Vegas Sands ( LVS) and Wynn Resorts will, for their parts, be the least affected, due to their significant presence in Asia, which is experiencing buoyancy.

Sands, for one, reported a narrower second-quarter loss on Wednesday, boosted by its properties in Macau and Singapore.

In fact, all of its operations outside of Asia missed expectations, while Sands China saw a 41% surge in revenue to $1.03 billion.

Wynn has already announced that its Las Vegas properties widened their operating loss in the second-quarter, but investors are waiting to see if its Macau casinos can offset these declines. Wynn is scheduled to report its second-quarter earnings after market.
