A Dutch pension fund has received a $100m (£65m) settlement after filing a lawsuit against technology firm HP.
PGGM, who acted as lead plaintiff in the US-based action, said shareholders suffered a loss in share prices as a result of the write-down.
It said HP "violated the federal securities laws by making a series of materially false statements and omissions in connection with and following the Autonomy acquisition regarding Autonomy's accounting practices and valuation".
Under the terms of the settlement, the cash will be used to compensate people who bought HP shares during the period between 19 August 2011 and 20 November 2012.
HP said the claim had "no merit" but it was "desirable and beneficial" to the firm and its shareholders to resolve the case.
"While HP believes the action has no merit, it is desirable and beneficial to HP and its shareholders to resolve the case as further litigation would be burdensome and protracted," said HP.
PGGM said it was pleased with the amount of the settlement, which is subject to court approval.
Eloy Lindeijer, chief investment management at PGGM Investments in the Netherlands, said: "PGGM has taken the responsibility of acting as lead plaintiff in this case because it is crucial that investors are timely and adequately informed by listed companies about material information that might impact shareholder's investment decisions. Therefore we have taken steps in the US in an effort to protect the investments of our clients and other aggrieved investors."
HP acquired the Cambridge-based company in October 2011 for $11bn (£7.1bn), but in November 2012 it decided to write down the value of Autonomy as it was "substantially overvalued".
In a statement published in November 2012, HP said: "The majority of this impairment charge, more than $5bn (£3.2bn), is linked to serious accounting improprieties, misrepresentation and disclosure failures discovered by an internal investigation by HP and forensic review into Autonomy's accounting practices prior to its acquisition by HP."
