NEW YORK (TheStreet) -- U.S. stock futures were falling Tuesday as investors became fixated on the possibility that Greece could default on its debt obligations.

Futures for the

Dow Jones Industrial Average

were sliding 54 points, or 59.8 points below fair value, at 12,596. Futures for the

S&P 500

were down 7.3 points, or 8.1 points below fair value, at 1304, and futures for the

Nasdaq

were lower by 10.5 points, or 9.4 points below fair value, at 2425.

Efforts toward providing debt-laden Greece with its second bailout package, backed by the European Union and International Monetary Fund and worth about 130 billion euros ($168 billion), have suffered another setback amid ongoing disagreements over a debt write-down deal.

In order to receive the next bailout package, Greece's private creditors have been asked to help Greece reduce its debt burden by about 100 billion euros by swapping their existing bonds holdings for ones lower in face value by 50% and with far longer maturities and lower interest rates. Private creditors have offered to swap in their existing Greek debt holdings for new ones with coupons of no lower than 4%, but eurozone finance ministers said the offer was still too steep. The euro had slid from a three-week high following the news and was now slipping 0.3% against the U.S. dollar.

Germany's denial of media reports saying that the country is open to boosting the firepower of the eurozone's rescue funds to 750 billion euros ($979 billion) also put a damper on market sentiment Tuesday morning.

"The Europeans are getting their butts kicked as they muddle through the euro-debt crisis, as there's been little thought given to growth and all of the concentration is on German-demanded austerity," said RealMoney columnist and Action Alerts PLUS portfolio manager Jim Cramer.

"We could easily use Europe as the reason for a selloff today. We haven't had a selloff in ages and we haven't had anything euro-driven since the beginning of the year when either the bears from across the ocean stopped crossing or they went into hibernation."

London's FTSE 100 was down 0.75%, and Germany's DAX was falling 0.91%. In Asia, Japan's Nikkei Average closed 0.22% higher. Hong Kong's Hang Seng index settled up 0.84%.

some profit in the fourth quarter, although the company said that high prices in 2012 will more than offset those losses in 2011.
