1.              Basis of Presentation and Summary of Significant Accounting Policies

Organization

The Company is a leading provider of data storage products. Its principal products are hard disk drives, commonly referred to as disk drives, hard drives or HDDs. Hard disk drives are devices that store digitally encoded data on rapidly rotating disks with magnetic surfaces. Disk drives are used as the primary medium for storing electronic data.

The Company produces a broad range of electronic data storage products addressing enterprise applications, where its products are designed for enterprise servers, mainframes and workstations; client compute applications, where its products are designed for desktop and notebook computers; and client non-compute applications, where its products are designed for a wide variety of end user devices such as digital video recorders (DVRs), gaming consoles, personal data backup systems, portable external storage systems and digital media systems. The Company sells its products primarily to major original equipment manufacturers (OEMs), distributors and retailers. In addition to manufacturing and selling disk drives, the Company provides storage services for small- to medium-sized businesses, including online backup, data protection and recovery solutions.

Basis of Presentation and Consolidation

The unaudited condensed consolidated financial statements include the accounts of the Company and all its wholly-owned and majority-owned subsidiaries, after elimination of intercompany transactions and balances. The preparation of financial statements in accordance with accounting principles generally accepted in the United States also requires management to make estimates and assumptions that affect the amounts reported in the Company’s consolidated financial statements and accompanying notes. Actual results could differ materially from those estimates. The methods, estimates and judgments the Company uses in applying its most critical accounting policies have a significant impact on the results the Company reports in its consolidated financial statements. The consolidated financial statements reflect, in the opinion of management, all material adjustments necessary to present fairly the consolidated financial position, results of operations, comprehensive income, cash flows and shareholders’ equity for the periods presented. Such adjustments are of a normal and recurring nature. The Company’s Consolidated Financial Statements for the fiscal year ended June 29, 2012, are included in its Annual Report on Form 10-K as filed with the United States Securities and Exchange Commission (SEC) on August 8, 2012. The Company believes that the disclosures included in the unaudited Condensed Consolidated Financial Statements, when read in conjunction with its Consolidated Financial Statements as of June 29, 2012, and the notes thereto, are adequate to make the information presented not misleading.

The results of operations for the three and six months ended December 28, 2012, are not necessarily indicative of the results of operations to be expected for any subsequent interim period in the Company’s fiscal year ending June 28, 2013. The Company operates and reports financial results on a fiscal year of 52 or 53 weeks ending on the Friday closest to June 30. The three and six months ended December 28, 2012 and December 30, 2011 each consisted of 13 weeks and 26 weeks, respectively.  Fiscal year 2013 will be comprised of 52 weeks and will end on June 28, 2013.

Summary of Significant Accounting Policies

Pursuant to our adoption of Accounting Standards Update No. 2011-05, Comprehensive Income (Topic 220)-Presentation of Comprehensive Income and Accounting Standards Update No. 2011-12, Comprehensive Income (Topic 220)-Deferral of the Effective Date for Amendments to the Presentation of Reclassifications of Items Out of Accumulated Other Comprehensive Income in Accounting Standards Update No. 2011-05, we elected to present separate consolidated statements of comprehensive income. Other than the revised indefinite lived intangible asset impairment testing described below, there have been no significant changes in our significant accounting policies. Please refer to Note 1 of “Financial Statements and Supplementary Data” contained in Part II, Item 8 of the Company’s Annual Report on Form 10-K for the fiscal year ended June 29, 2012, as filed with the SEC on August 8, 2012 for a discussion of the Company’s other significant accounting policies.

Recently Issued Accounting Pronouncements

In July 2012, the FASB issued ASU No. 2012-02, Intangibles — Goodwill and Other (ASC Topic 350) — Testing Indefinite-Lived Intangible Assets for Impairment. The ASU allows companies the option to perform a qualitative assessment in determining whether it is more likely than not that an indefinite-lived intangible asset is impaired as a basis for determining whether it is necessary to perform the quantitative impairment test. The Company has early adopted the ASU in the first quarter of fiscal year 2013. As required by the new ASU, the Company tests indefinite-lived intangible assets for impairment whenever events occur or circumstances change, such as declining financial performance, deterioration in the environment in which the entity operates or deteriorating macroeconomic conditions that have a negative effect on future expected earnings and cash flows that could affect significant inputs used to determine the fair value of the indefinite-lived intangible asset. The adoption of this new guidance did not have an impact on the Company’s consolidated financial statements.

2.              Balance Sheet Information

Investments

The Company’s short-term investments are primarily comprised of readily marketable securities with remaining maturities of more than 90 days at the time of purchase. With the exception of securities held for its non-qualified deferred compensation plan, which are classified as trading securities, the Company classifies its investment portfolio as available-for-sale. The Company recognizes its available-for-sale investments at fair value with unrealized gains and losses included in Accumulated other comprehensive income (loss), which is a component of equity. The amortized cost of debt securities is adjusted for amortization of premiums and accretion of discounts to maturity. Such amortization and accretion are included in Interest income. Realized gains and losses are included in Other, net. The cost of securities sold is based on the specific identification method.

As of December 28, 2012, the Company’s Restricted cash and investments consisted of $76 million in cash equivalents and investments held in trust for payment of its non-qualified deferred compensation plan liabilities and $22 million in cash and investments held as collateral at banks for various performance obligations. As of June 29, 2012, the Company’s Restricted cash and investments consisted of $73 million in cash equivalents and investments held in trust for payment of its non-qualified deferred compensation plan liabilities and $20 million in cash and investments held as collateral at banks for various performance obligations.

The following table summarizes, by major type, the fair value and amortized cost of the Company’s investments as of December 28, 2012:

The Company’s available-for-sale securities include investments in auction rate securities. Beginning in fiscal year 2008, the Company’s auction rate securities failed to settle at auction and have continued to fail through December 28, 2012. Since the Company continues to earn interest on its auction rate securities at the maximum contractual rate, there have been no payment defaults with respect to such securities, and they are all collateralized, the Company expects to recover the entire amortized cost basis of these auction rate securities. The Company does not intend to sell these securities and has concluded it is not more likely than not that the Company will be required to sell the securities before the recovery of their amortized cost basis. Given the uncertainty as to when the liquidity issues associated with these securities will improve, these securities are classified within Other assets, net in the Company’s Condensed Consolidated Balance Sheets.

Table of Contents

As of December 28, 2012, with the exception of the Company’s auction rate securities, the Company had no material available-for-sale securities that had been in a continuous unrealized loss position for a period greater than 12 months. The Company determined no available-for-sale securities were other-than-temporarily impaired as of December 28, 2012.

The fair value and amortized cost of the Company’s investments classified as available-for-sale at December 28, 2012, by remaining contractual maturity were as follows:

Equity securities which do not have a contractual maturity date are not included in the above table.

The following table summarizes, by major type, the fair value and amortized cost of the Company’s investments as of June 29, 2012:

As of June 29, 2012, with the exception of the Company’s auction rate securities, the Company had no available-for-sale securities that had been in a continuous unrealized loss position for a period greater than 12 months. The Company determined no available-for-sale securities were other-than-temporarily impaired as of June 29, 2012.

Strategic Investments

The Company enters into certain strategic investments for the promotion of business and strategic objectives. Strategic investments are included in Other assets, net in the Condensed Consolidated Balance Sheets, are recorded at cost and are periodically analyzed to determine whether or not there are indicators of impairment. The carrying value of the Company’s strategic investments at December 28, 2012 and June 29, 2012 totaled $27 million and $40 million, respectively.

3.              Debt

Short-Term Borrowings

On January 18, 2011, the Company and its subsidiary, Seagate HDD Cayman (“the Borrower”), entered into a credit agreement which provides for a $350 million senior secured revolving credit facility. Seagate Technology plc and certain of its material subsidiaries fully and unconditionally guarantee, on a senior secured basis, the revolving credit facility. The revolving credit facility matures in January 2015. The $350 million revolving credit facility is available for cash borrowings and for the issuance of letters of credit up to a sub-limit of $75 million. As of December 28, 2012, no borrowings have been drawn under the revolving credit facility, and $2 million had been utilized for letters of credit.

The issuer under the 2014 Notes is Seagate Technology International, and the obligations under the 2014 Notes are unconditionally guaranteed by the Company and certain of its significant subsidiaries. In addition, the obligations under the 2014 Notes are secured by a second-priority lien on substantially all of the Company’s tangible and intangible assets. The indenture governing the 2014 Notes contains covenants that limit the Company’s ability, and the ability of certain of its subsidiaries, (subject to certain exceptions) to incur additional debt or issue certain preferred shares, create liens, enter into mergers, pay dividends, redeem or repurchase debt or shares, and enter into certain transactions with the Company’s shareholders or affiliates.

During the first six months of fiscal year 2013, the Company redeemed $53 million aggregate principal amount of its 2018 Notes for cash at a premium to their principal amount, plus accrued and unpaid interest. The Company recorded a loss on the redemptions of approximately $6 million for the three and six months ended December 28, 2012, which is included in Other, net in the Company’s Condensed Consolidated Statements of Operations.

$600 million Aggregate Principal Amount of 6.875% Senior Notes due May 2020 (the “2020 Notes”). The interest on the 2020 Notes is payable semi-annually on May 1 and November 1 of each year.

Other As part of our acquisition of LaCie S.A. during the six months ended December 28, 2012, long-term debt of $6 million was acquired, of which $3 million is classified as current.

At December 28, 2012, future principal payments on long-term debt were as follows (in millions):

4.              Income Taxes

The income tax provision of $7 million recorded for the three months ended December 28, 2012 included approximately $6 million of net discrete tax benefits primarily from the release of tax reserves associated with the expiration of certain statutes of limitation. The income tax provision of $25 million recorded for the six months ended December 28, 2012 included approximately $1 million of net discrete tax expense primarily associated with the reversal of prior period tax benefits offset by the release of tax reserves associated with the expiration of certain statutes of limitation.

The Company’s income tax provision recorded for the three and six months ended December 28, 2012 differed from the provision for income taxes that would be derived by applying the Irish statutory rate of 25% to income before income taxes, primarily due to the net effect of (i) tax benefits related to non-U.S. earnings generated in jurisdictions that are subject to tax holidays or tax incentive programs and are considered indefinitely reinvested outside of Ireland and (ii) a decrease in valuation allowance for certain U.S. deferred tax assets.

During the six months ended December 28, 2012, the Company’s unrecognized tax benefits excluding interest and penalties increased by $9 million to $144 million. The unrecognized tax benefits that, if recognized, would impact the effective tax rate were $144 million at December 28, 2012, subject to certain future valuation allowance reversals. During the 12 months beginning December 29, 2012, the Company expects to reduce its unrecognized tax benefits by approximately $3 million primarily as a result of the expiration of certain statutes of limitation.

The income tax benefit of $5 million recorded for the three months ended December 30, 2011 included $7 million of tax benefit from the reversal of a portion of the U.S. valuation allowance recorded in prior periods. The income tax provision of $6 million recorded for the six months ended December 30, 2011 included approximately $10 million of discrete tax benefits from the reversal of a portion of the U.S. valuation allowance recorded in prior periods and the release of tax reserves associated with the expiration of certain statutes of limitation.

Table of Contents

The Company’s income tax benefit and provision recorded for the three and six months ended December 30, 2011 differed from the provision for income taxes that would be derived by applying the Irish statutory rate of 25% to income before income taxes primarily due to the net effect of (i) tax benefits related to non-U.S. earnings generated in jurisdictions that are subject to tax holidays or tax incentive programs and are considered indefinitely reinvested outside of Ireland, (ii) a decrease in valuation allowance for certain U.S. deferred tax assets,  (iii) the release of tax reserves as a result of the expiration of statutes of limitation, and (iv) tax expense related to intercompany transactions.

5.              Acquisitions

LaCie S.A .

On August 3, 2012 the Company acquired 23,382,904 (or approximately 64.5%) of the outstanding shares of LaCie S.A. (“LaCie”) for a price of €4.05 per share with a price supplement of €0.12 per share, which is payable if the Company successfully acquires at least 95% of the outstanding shares of LaCie within 6 months of the acquisition. Of the amount paid at the acquisition date, €9 million is treated as compensation cost to one of the selling shareholders, who is now an employee of the Company, to be recognized over a period of 36 months from the acquisition date, and may be refunded to the Company if the selling shareholder is no longer employed at the end of that period. The transaction and related agreements are expected to accelerate the Company’s growth strategy in the expanding consumer storage market, particularly in Europe, Japan and in premium distribution channels.

The acquisition-date fair value of the consideration transferred for the business combination totaled $111 million, including cash paid of $107 million, and contingent consideration of $4 million.

The following table summarizes the estimated fair values of the assets acquired, liabilities assumed, and noncontrolling interest at the acquisition date (in millions):

The following table shows the fair value of the separately identifiable intangible assets at the time of acquisition and the period over which each intangible asset will be amortized:

Since acquisition date, the Company recorded adjustments to the fair value of certain assets acquired and liabilities assumed with LaCie S.A. that resulted in a net increase of $1 million to Goodwill, and a corresponding decrease in Intangible assets.

13

Table of Contents

The goodwill recognized is attributable primarily to the benefits the Company expects to derive from LaCie’s brand recognition and the acquired workforce, and is not deductible for income tax purposes. The acquisition date fair value of the noncontrolling interest is based on the market price of their publicly traded shares as of the first trading date subsequent to the acquisition, as the shares did not trade on the acquisition date.

The amounts assigned to assets acquired and liabilities assumed in the acquisition are preliminary and subject to revision as more detailed analyses are completed and additional information about fair value of assets and liabilities becomes available, including information relating to our valuation of identified intangible assets.

The Company incurred $1 million of expenses related to the acquisition of LaCie during the six months ended December 28, 2012, which are included within Marketing and administrative expense on the Condensed Consolidated Statement of Operations.

The amounts of revenue and earnings of LaCie included in the Company’s Condensed Consolidated Statement of Operations from the acquisition date were not significant.

The Company deposited $72 million into an escrow account with the intention of acquiring the remaining publicly held shares of LaCie through public and private transactions. As of December 28, 2012, a total of $59 million of the Company’s deposit had been used to acquire an additional 29% of the outstanding shares, resulting in an ending ownership interest of approximately 93.5%.

Samsung Hard Disk Drive (“HDD”) Operations

On December 19, 2011, the Company completed the acquisition of Samsung Electronics Co., Ltd’s (“Samsung”) hard disk drive (“HDD”) business pursuant to an Asset Purchase Agreement (“APA”) by which the Company acquired certain assets and liabilities of Samsung relating to the research and development, manufacture and sale of hard-disk drives. The transaction and related agreements are expected to improve the Company’s position as a supplier of 2.5-inch products; position the Company to better address rapidly evolving opportunities in markets including, but not limited to, mobile computing, cloud computing and solid state storage; expand the Company’s customer access in China and Southeast Asia; and accelerate time to market for new products.

The acquisition-date fair value of the consideration transferred totaled $1,140 million, which consisted of $571 million of cash, $10 million of which was paid as a deposit upon signing the APA in the fourth quarter of fiscal year 2011, and 45.2 million ordinary shares with a fair value of $569 million. The fair value of the ordinary shares issued was determined based on the closing market price of the Company’s ordinary shares on the acquisition date, less a 16.5% discount for lack of marketability as the shares issued are subject to a restriction that limits their trade or transfer for approximately a one year period.

The following table summarizes the fair values of the assets acquired and liabilities assumed at the acquisition date (in millions):

14

Table of Contents

The following table shows the fair value of the separately identifiable intangible assets at the time of acquisition and the period over which each intangible asset will be amortized:

Since acquisition date, the Company recorded adjustments to the fair value of certain assets acquired and liabilities assumed with the Samsung HDD business that resulted in a net decrease of $5 million to Goodwill. These adjustments included a $7 million increase in Other assets for spare parts and a $3 million increase to Equipment, offset by a $3 million increase in Warranty liability and a $2 million increase in Other liabilities related to certain assumed vendor obligations.

The $432 million of goodwill recognized is attributable primarily to the benefits the Company expects to derive from enhanced scale and efficiency to better serve its markets and expanded customer presence in China and Southeast Asia. Except for approximately $4 million of goodwill relating to assembled workforce in Korea, none of the goodwill is expected to be deductible for income tax purposes.

The unaudited pro forma financial results presented below for the three and six months ended December 30, 2011, include the effects of pro forma adjustments as if the acquisition date occurred as of the beginning of the prior fiscal year on July 2, 2011. The pro forma results combine the historical results of the Company for the three and six months ended December 30, 2011 and the historical results of the acquired assets and liabilities of Samsung’s HDD business, and include the effects of certain fair value adjustments and the elimination of certain activities excluded from the transaction. The pro forma financial information is presented for informational purposes only and is not necessarily indicative of the results of operations that would have been achieved if the acquisition had taken place at the beginning of the earliest period presented, nor is it intended to be a projection of future results.

The pro forma results for the three and six months ended December 30, 2011, include adjustments of $33 million and $85 million, respectively, to reflect the additional depreciation and amortization that would have been charged assuming the fair value adjustments to property, plant and equipment and intangible assets had been applied on July 2, 2011.

6.              Goodwill and Other Intangible Assets

The changes in the carrying amount of goodwill for the six months ended December 28, 2012, are as follows:
