On May 29, 2014, Avago Technologies Limited (“Avago” or the “Company”) issued a press release announcing unaudited financial results for the second quarter, ended May 4, 2014, of its fiscal year 2014. The Company will host an investor conference call on May 29, 2014 at 2:00 p.m. Pacific Time to discuss these results.

The foregoing description is qualified in its entirety by reference to the press release dated May 29, 2014, a copy of which is attached hereto as Exhibit 99.1.

On May 13, 2014, the Company announced that it was implementing cost reduction activities associated with its recently completed acquisition of LSI Corporation (“LSI”). As part of this exercise Avago expects to eliminate approximately 1,100 positions from its workforce across all business and functional areas on a global basis. In connection with this action, the Company expects to take charges of between approximately $120 million and $140 million, in the aggregate, over its next six fiscal quarters. The Company does not plan to further update these estimates but will provide details of LSI acquisition-related restructuring costs and expenses as part of its quarterly financial reporting.

On May 29, 2014, LSI entered into an Asset Purchase Agreement with Seagate Technology LLC (“Seagate”), pursuant to which LSI has agreed to sell its Flash Components Division and Accelerated Solutions Division to Seagate for $450 million in cash. These divisions comprise LSI’s flash business. Each of the parties has made customary representations and warranties in the Asset Purchase Agreement. Consummation of the transaction is subject to the satisfaction or waiver of customary closing conditions and receipt of certain regulatory approvals, including the expiration or termination of the waiting period under the Hart-Scott-Rodino Antitrust Improvements Act of 1976. The transaction is presently expected to close in the third calendar quarter of 2014.

The information contained in Item 2.02 of this report, including Exhibit 99.1, shall not be incorporated by reference into any filing of the registrant, whether made before or after the date hereof, regardless of any general incorporation language in such filing, unless expressly incorporated by specific reference to such filing. The information in this report, including the exhibit hereto, shall not be deemed to be “filed” for purposes of Section 18 of the Securities Exchange Act of 1934, as amended, or otherwise subject to the liabilities of that section.
