On June 6 and 7, 2011, two putative stockholder class action lawsuits (Case No. 111CV202403 (the “Bushansky action”) and Case No. 111CV202501 (the “Venette action”), respectively) were filed in California Superior Court in Santa Clara County naming Advanced Analogic Technologies Inc.

On July 26, 2011, the Court issued an order consolidating the Bushansky action and Venette action into a single, consolidated action captioned In re Advanced Analogic Technologies Inc.

On November 30, 2011, following confidential arbitration proceedings in the Delaware Court of Chancery, the Company announced that it and AATI had amended their previously announced merger agreement whereby the Company would acquire AATI at a reduced price through a tender offer. The Company and AATI completed the transaction on January 9, 2012. On March 2, 2012, the Court stayed all discovery in the matter and ordered that Plaintiffs file an amended complaint by April 20, 2012. On April 20, 2012, Plaintiffs filed an amended complaint (“First Amended Complaint”) against each of the original defendants with the exception of Merger Sub. The First Amended Complaint alleges, among other things, that (1) members of AATI's board of directors breached their fiduciary duties by (a) failing to take steps to maximize the value of AATI to its public shareholders by failing to adequately consider potential acquirers, (b) agreeing to the merger for inadequate consideration on unfair terms; (c) causing the filing of a materially misleading Schedule 14D-9 that failed to (i) disclose a basis for the price reduction, (ii) describe the arbitration proceedings, and (iii) include any financial valuation or fairness opinion concerning whether the revised merger consideration was fair; and (d) causing the issuance of amendments to the Schedule 14D-9 that failed to respond adequately to the SEC's disclosure directives; and (2) Skyworks and AATI allegedly aided and abetted these purported breaches of fiduciary duties. On June 22, 2012, the defendants filed demurrers to the First Amended Complaint. The Court will hold a hearing on those demurrers on February 15, 2013.

At the time of this filing, the Company had not recorded any accrual for loss contingencies associated with its legal proceedings as losses resulting from such matters were determined to be remote. In addition, the Company does not believe there are any legal proceedings that are reasonably possible to result in a material loss. We are engaged in various other legal actions, not described above, in the normal course of business and, while there can be no assurances, the Company believes the outcome of all pending litigation involving the Company will not have, individually or in the aggregate, a material adverse effect on our business. Guarantees and Indemnifications The Company has made no contractual guarantees for the benefit of third parties. However, the Company generally indemnifies its customers from third-party intellectual property infringement litigation claims related to its products, and, on occasion, also provides other indemnities related to product sales. In connection with certain facility leases, the Company has indemnified its lessors for certain claims arising from the Company's activities at the facility or out of the lease. The Company indemnifies its directors and officers to the maximum extent permitted under the laws of the state of Delaware. The duration of the indemnities varies, and in many cases is indefinite. The indemnities to customers in connection with product sales generally are subject to limits based upon the amount of the related product sales and in many cases are subject to geographic and other restrictions. In certain instances, the Company's indemnities do not provide for any limitation of the maximum potential future payments the Company could be obligated to make. As of December 28, 2012, the Company had not recorded any liability for these indemnities in the accompanying consolidated balance sheets. The Company continues to monitor and reassess indemnities each reporting period.
