Litigation and Contingencies Policy
HP is involved in lawsuits, claims, investigations and proceedings, including those identified below, consisting of intellectual property, commercial, securities, employment, employee benefits and environmental matters that arise in the ordinary course of business. HP records a provision for a liability when management believes that it is both probable that a liability has been incurred and the amount of the loss can be reasonably estimated. HP believes it has adequate provisions for any such matters, and, as of April 30, 2011, it was not reasonably possible that an additional material loss had been incurred in an amount in excess of the amounts already recognized on HP's financial statements. HP reviews these provisions at least quarterly and adjusts these provisions to reflect the impact of negotiations, settlements, rulings, advice of legal counsel, and other information and events pertaining to a particular case. Based on its experience, HP believes that any damage amounts claimed in the specific matters discussed below are not a meaningful indicator of HP's potential liability. Litigation is inherently unpredictable. However, HP believes that it has valid defenses with respect to legal matters pending against it. Nevertheless, cash flows or results of operations could be materially affected in any particular period by the unfavorable resolution of one or more of these contingencies.
