Basis of Presentation
The consolidated financial statements include the accounts of the Company and its wholly owned subsidiaries.
All significant intercompany accounts and transactions have been eliminated in consolidation. In fiscal 2013, the
accounts for all foreign subsidiaries have been remeasured using the U.S. dollar as the functional currency. In fiscal
2012, the accounts for all foreign subsidiaries, except for one Japanese subsidiary in which Yen was the functional
currency, have been remeasured using the U.S. dollar as the functional currency. Gains or losses resulting from
remeasurement or translation of these accounts from local currencies into U.S. dollars were immaterial to the con-
solidated financial statements.
On March 8, 2012 ("Closing Date"), the Company completed its acquisition ("the Acquisition") of all of the
issued and paid-up share capital of Viviti Technologies Ltd., known until shortly before the Acquisition as Hitachi
Global Storage Technologies Holdings Pte. Ltd. ("HGST") from Hitachi, Ltd. ("Hitachi"). The acquisition is further
described in Note 14. The results of operations of HGST since the date of Acquisition are included in the consolidated

Cash and Cash Equivalents
The Company's cash equivalents represent highly liquid investments in money market funds, which are invested
in U.S. Treasury securities, U.S. Treasury bills and U.S. Government agency securities with original maturities when
purchased of three months or less.
The Company's investments consist of auction-rate securities, which are primarily backed by insurance products
with original maturities greater than three months. The Company has classified these investments as available-for-sale
securities and they are carried at fair value within other non-current assets in the consolidated balance sheets. In addi-
tion, the Company enters into certain strategic investments for the promotion of business and strategic objectives.
These strategic investments are recorded at cost within other non-current assets in the consolidated balance sheets and
are periodically analyzed to determine whether or not there are indicators of impairment.
