HP's chief executive Meg Whitman has defended the firm's acquisition processes during its $10bn purchase of UK firm Autonomy after serious accounting irregularities and improprieties have come to light, costing the firm $8.8bn in write-downs.
The revelations came to light on Tuesday during HP's fourth quarter earnings for 2012, in which it accused management at Autonomy of "accounting improprieties, misrepresentations and disclosure failures to inflate the underlying financial metrics of the company".
Speaking on a conference call Whitman said the firm had carried out all necessary checks on the firm in conjunctions with major accounting and consultancy firms like KPMG and Deloitte prior to the deal.
"We had no idea there were any misrepresentations going on prior to the individual coming forward after Mike Lynch was let go after our Q2 earnings," she said.
She went on to say it was almost impossible for the firm, or those it hired to oversee the deal, to uncover the problems, as they were being lied to about the reality of many of the figures on Autonomy's books.
This including using sales to value added resellers (VARs) as actual customer deals and rejigging long-term customer deals gained during acquisitions into what appeared to be new sales.
The firm is now pursuing actions through both civil and criminal courts against those it believes responsible, although it refused to name any individuals.
HP said it hopes to try and gain back as much lost revenue from the write-down as possible for shareholders
Despite this, Whitman said HP remains committed to the use of Autonomy's technology across the company.
"We have confirmed with hands on experience over the year it's [its technology] cutting edge and offers many unique solutions to computing challenges faced by businesses," she said.
Nevertheless, with hardware PC sales slumping in the face of tablets, and HP's profits shrinking, forcing massive layoffs, the huge shock of the claims made about Autonomy's financials practices prior to the acquisition add yet another major headache to Whitman's workload.
