With sales of its storage software dropping, Symantec plans to lay off some staff as part of plans to cut $200 million (£101.7m) in expenses.

The cuts were announced Wednesday as Symantec posted financial results that fell short of expectations. Symantec reported earnings of $0.12 per share on $1.31 billion (£666m) in revenue for its third quarter of fiscal 2007, ended 29 December. The software vendor had previously said that it expected earnings per share in the range of $0.14 or $0.15 and revenue as high as $1.35 billion.

Symantec had warned of the poor results a week ago, putting some of the blame on its Data Centre Management Group, which sells the storage software Symantec acquired in its 2005 purchase of Veritas.

Revenue for this business declined 8% year on year, Symantec said. This product line represents more than a quarter of Symantec's overall business, it added.

Geographically, Symantec also posted sluggish 5% growth in the Americas, Europe, the Middle East and Africa.

Symantec said it plans to cut $200 million in costs by reducing hiring, consolidating some of its offices, and by making some staff reductions.

The software vendor's consumer business, newly under threat from Microsoft's competing security products, was a bright spot for the quarter. Revenue there was up 24%, Symantec said.
