ROUND ROCK, Texas: Dell Computer - by adspend the globe's 28th largest advertiser in 2006 - is to restate its results for fiscal years 2003-2006, plus the first quarter of fiscal 2007.

The restatement will drain the world number two computer maker's reported profit over the period by $50 million (€37.06m; £25.22m) to $150m - not "a huge sum", as the Wall Street Journal observes, "for a company that posted net income of about $12 billion over the four-year period."

The problems came to light in August 2006 when Dell revealed it's accounting methods were under investigation by the Securities & Exchange Commission. Whereupon the company's audit committee launched its own probe.

These "accounting errors and irregularities" won't occur again, promises Dell's cfo Donald J Carty, who took up the post in January 2007.

He says will take "remedial" action against unspecified employees that include "terminations, reassignments, reprimands, increased supervision, training and imposition of financial penalties."

Forbes magazine ranks Dell 194th in its list of the planet's top 2000 brands by market value.
