US futures pointed to a moderately weaker open on Wall Street on Tuesday but the mood may be dictated early in the session by the release of service sector activity data due shortly after the open.
Results from Cisco Systems, the world's largest supplier of telecoms equipment for internet traffic, will be keenly watched after the close of the session.
Companies reporting before the open include Gillette, Prudential Financial, Tommy Hilfiger and Costco.
At 1100 GMT the Dow Jones Industrial Average futures were 13 points weaker, the S&P 500 futures were 0.8 points lower and the Nasdaq futures were 0.5 points softer.
In economic news the Institute for Supply Management is expected to release its non-manufacturing survey at 1400 GMT. Analysts are expecting a slight contraction in the figure from last month's reading of 60.6.
"Anything above the 55 - 56 area would be a good outcome in trend terms," said Ian Gunner, strategist at Mellon Financial, who highlighted the index's rise since its low levels this spring. In March, the headline index slipped to 47.9.
Results from Costco may dent sentiment in the retail sector. The US's sixth largest retailer lowered its fourth quarter outlook because of the rising costs of healthcare for its employees and tighter margins.
After the market closes Cisco Systems will report its quarterly earnings. Analysts expect the computer networking group to report earnings of 15 cents per share, according to the latest consensus estimate.
General Electric may also be in demand early on after it emerged the company is to pay $5.4bn for Transamerica Finance Corp., owned by Dutch insurer Aegon.
