Commitments and Contingencies	Note 9. Commitments and Contingencies *Commitments* In July 2013, the Company entered into a lease agreement to continue renting its existing space in Aachen, Germany through July 31, 2023. The building serves as the Company’s European headquarters and houses most of the manufacturing operations for its Impella product line.

In some actions, the claimants seek damages, as well as other relief, which, if granted, would require significant expenditures. The Company records a liability in its consolidated financial statements for these matters when a loss is known or considered probable and the amount can be reasonably estimated. The Company reviews these estimates each accounting period as additional information is known and adjusts the loss provision when appropriate. If a matter is both probable to result in liability and the amounts of loss can be reasonably estimated, the Company estimates and discloses the possible loss or range of loss. If the loss is not probable or cannot be reasonably estimated, a liability is not recorded in its consolidated financial statements. On October 26, 2012, the Company was informed that the United States Attorney’s Office for the District of Columbia is conducting an investigation that is focused on the Company’s marketing and labeling of the Impella 2.5. On October 31, 2012, the Company accepted service of a subpoena related to this investigation. The subpoena seeks documents related to the Impella 2.5. The Company is in the process of responding and is cooperating fully with the subpoena. The Company expects to substantially complete the requested document production by the end of fiscal 2014. On September 13, 2013, the Company entered into a tolling agreement with the United States Attorney’s Office, pursuant to which the Company and the United States Attorney’s Office mutually agreed to toll the applicable statutes of limitations for all criminal, civil and administrative offenses and violations that could be charged or claimed against the Company as of that date until June 2, 2014. Because the investigation is in the early stages, management is unable to predict the ultimate outcome or determine whether a liability has been incurred or make an estimate of the reasonably possible liability, if any, that could result from any unfavorable outcome associated with this inquiry. The Company can anticipate, however, that it will incur significant expenses related to this investigation. On November 16 and 19, 2012, two purported class action complaints were filed against the Company and certain of its officers in the U.S. District Court for the District of Massachusetts by alleged purchasers of its common stock, on behalf of themselves and persons or entities that purchased or acquired securities of the Company between August 5, 2011 and October 31, 2012. The complaints alleged that the defendants violated the federal securities laws in connection with disclosures related to the U.S. Food and Drug Administration and the marketing and labeling of the Company’s Impella 2.5 product and seek damages in an unspecified amount. The Court has consolidated these complaints and a consolidated amended complaint was filed by the plaintiffs on May 20, 2013. On July 8, 2013, the Company filed a motion to dismiss the consolidated complaint. Oral argument on the Company’s motion to dismiss was conducted before the presiding district court judge on September 18, 2013. On February 4, 2013, an alleged stockholder of the Company filed a derivative action on the Company’s behalf against each of the Company’s directors in the U.S. District Court for the District of Massachusetts. The complaint alleged that the directors breached their fiduciary duties to the Company and its stockholders in connection with disclosures related to the FDA and the marketing and labeling of the Company’s Impella 2.5 product and sought damages in an unspecified amount. On March 22, 2013, the Company filed a motion to dismiss the derivative action due to the plaintiff’s failure to make a proper demand on the Company’s board of directors. On June 21, 2013, the District Court entered an order granting the Company’s motion and dismissing the derivative action in its entirety. On July 19, 2013, the plaintiff filed an appeal of the dismissal in the United States Court of Appeals for the First Circuit. Oral argument was conducted before the appellate court on February 5, 2014. The Company is unable to estimate its potential liability with respect to the Department of Justice investigation, the purported class action claim and the appeal of the dismissal of the derivative claims. There are numerous factors that make it difficult to meaningfully estimate possible loss or range of loss at this stage of the investigation and lawsuits, including that: the proceedings are in relatively early stages, there are significant factual and legal issues to be resolved, information obtained or rulings made during any lawsuits or investigations could affect the methodology for calculation. In addition, with respect to claims where damages are the requested relief, no amount of loss or damages has been specified. Therefore, the Company is unable at this time to estimate its possible losses and accordingly, no adjustment has been made to the financial statements to reflect the outcome of these uncertainties.
