U.S. stock index futures rose ahead of the open, although gains were pared slightly after a lower-than-expected revision to the fourth-quarter Gross Domestic Product.
The economy grew at a 2.8 percent pacein the fourth quarter, down from an initial estimate of an annualized rate of 3.2 percent, the Commerce Department reported Friday. Economists had expected the revision to rise to 3.3 percent.
Futures got a boost as oil prices fell on assurances from Saudi Arabia that it can pump more oil to cover for a fall in Libyan exports caused by the turmoil in the country. U.S. light sweet crude for April delivery fell below $97 a barrel, while Brent London crude was flat at about $111 a barrel.
An unconfirmed rumor about the possible shooting of Libyan leader Muammar Gaddafi sent oil prices plunging late on Thursday.
