Accenture Plc reported market-beating quarterly results, and the technology outsourcing and consulting company also forecast a strong 2012, allaying fears of an industry-wide slowdown triggered by a slowing U.S. economy and debt crisis in Europe.

Grand Canal Harbour, Ireland-based Accenture said its new bookings -- a key indicator of future sales -- of $8.4 billion in the fourth quarter was the company's highest quarterly bookings ever.

Accenture forecast full-year earnings of $3.80-$3.88 per share, above analysts' average expectations of $3.76 per share, according to Thomson Reuters I/B/E/S.

It forecast full-year revenue growth of 7-10 percent, which implies a range of $27.3-$28.05 billion, according to Reuters calculations. This was on the higher end of analysts' average expectations of $27.43 billion.

We have seen this with Oracle and this (forecast) seems to affirm that IT enterprise spending remains strong, Josh Olson, technology analyst for Edward Jones said by phone.

It looks like their core growth strategy has good momentum in both geographies and segments, the analyst said.

Oracle Corp last week gave a strong second-quarter outlook, fueled by robust software sales.

For the first quarter, Accenture forecast revenue to be in the range of $6.8-$7.0 billion, ahead of analysts' average estimates of $6.7 billion.

The company also increased its semi-annual cash dividend 50 percent, to 67.5 cents per share, and approved $5 billion of additional share repurchase authority.

Fourth-quarter consulting net revenue rose to $3.9 billion. Outsourcing net revenue was $2.8 billion, an increase of 21 percent.

Shares of the company were up more than 4 percent in trading after the bell. They closed at $53.65 on Tuesday on the New York Stock Exchange.
