| Notes to Financial Statements [Abstract] | |
| Variable Interest Entities | Variable Interest Entities We have interests in joint venture entities that are Variable Interest Entities ("VIEs"). If we are the primary beneficiary of a VIE, we are required to consolidate it. To determine if we are the primary beneficiary, we evaluate whether we have the power to direct the activities that most significantly impact the VIE's economic performance and the obligation to absorb losses or the right to receive benefits of the VIE that could potentially be significant to the VIE. Our evaluation includes identification of significant activities and an assessment of our ability to direct those activities based on governance provisions and arrangements to provide or receive product and process technology, product supply, operations services, equity funding, financing and other applicable agreements and circumstances. Our assessments of whether we are the primary beneficiary of our VIEs require significant assumptions and judgment. Unconsolidated Variable Interest Entities Inotera – Inotera Memories, Inc. ("Inotera") is a VIE because of the terms of its supply agreement with us and our partner, Nanya Technology Corporation ("Nanya"). We have determined that we do not have power to direct the activities of Inotera that most significantly impact its economic performance, primarily due to (1) limitations on our governance rights that require the consent of other parties for key operating decisions and (2) our dependence on our joint venture partner for financing and the ability to operate in Taiwan. Therefore, we account for our interest in Inotera under the equity method. Transform – Transform Solar Pty Ltd. ("Transform") is a VIE because its equity is not sufficient to permit it to finance its activities without additional financial support from us or our partner, Origin Energy Limited ("Origin"). We have determined that we do not have power to direct the activities of Transform that most significantly impact its economic performance, primarily due to limitations on our governance rights that require the consent of Origin for key operating decisions. Therefore, we account for our interest in Transform under the equity method. EQUVO – EQUVO HK Limited (“EQUVO”) is a special purpose entity created to facilitate an equipment sale-leaseback financing transaction between us and a consortium of financial institutions. Neither we nor the financial institutions have an equity interest in EQUVO. EQUVO is a VIE because its equity is not sufficient to permit it to finance its activities without additional support from the financial institutions and because the third-party equity holder lacks characteristics of a controlling financial interest. By design, the EQUVO arrangement is merely a financing vehicle and we do not bear any significant risks from variable interests with EQUVO. Therefore, we have determined that we do not have the power to direct the activities of EQUVO that impact its economic performance and we do not consolidate EQUVO. For further information regarding our VIEs that we account for under the equity method, see "Equity Method Investments" note. Consolidated Variable Interest Entities IMFT and IMFS – IM Flash Technologies, LLC ("IMFT") and IM Flash Singapore, LLP ("IMFS") are both VIEs because all of their costs are passed to us and our partner, Intel Corporation ("Intel"), through product purchase agreements and they are dependent upon us or Intel for any additional cash requirements. For both IM Flash entities (i.e., IMFT and IMFS), we determined that we have the power to direct the activities of the entities that most significantly impact their economic performance. The primary activities of the IM Flash entities are driven by the constant introduction of product and process technology. Because we perform a significant majority of the technology development, we have the power to direct key activities of the entities. In addition, IMFT manufactures certain products exclusively for us using our technology. As a result of our 82% ownership interest in IMFS as of March 1, 2012, we had significantly greater economic exposure than Intel. We also determined that we have the obligation to absorb losses and the right to receive benefits from the IM Flash entities that could potentially be significant to these entities. Therefore, we consolidate the IM Flash entities. On February 27, 2012, we entered into agreements with Intel relating to our IMFS and IMFT joint ventures. The transactions contemplated by such agreements became effective on April 6, 2012. For further information regarding the effect of these agreements, see "IM Flash Agreements" note. MP Mask – MP Mask Technology Center, LLC ("MP Mask") is a VIE because all of its costs are passed to us and our partner, Photronics, Inc. ("Photronics"), through product purchase agreements and it is dependent upon us or Photronics for any additional cash requirements. We determined that we have the power to direct the activities of MP Mask that most significantly impact its economic performance, primarily because (1) of our tie-breaking voting rights over key operating decisions and (2) nearly all key MP Mask activities are driven by our supply needs. We also determined that we have the obligation to absorb losses and the right to receive benefits from MP Mask that could potentially be significant to MP Mask. Therefore, we consolidate MP Mask. For further information regarding our consolidated VIEs, see "Consolidated Variable Interest Entities" note. |

| Recently Issued Accounting Standards | Recently Issued Accounting Standards In May 2011, the Financial Accounting Standards Board ("FASB") issued a new accounting standard on fair value measurements that clarifies the application of existing guidance and disclosure requirements, changes certain fair value measurement principles and requires additional disclosures about fair value measurements. We are required to adopt this standard in the third quarter of 2012. We do not expect this adoption to have a material impact on our financial statements. In June 2011, the FASB issued a new accounting standard on the presentation of comprehensive income. The new standard requires the presentation of comprehensive income, the components of net income and the components of other comprehensive income either in a single continuous statement of comprehensive income or in two separate but consecutive statements. We are required to adopt this standard as of the beginning of 2013. The new standard also required presentation of adjustments for items that are reclassified from other comprehensive income to net income in the statement where the components of net income and the components of other comprehensive income are presented, which was indefinitely deferred by an update issued by the FASB in December 2011. The adoption of these standards will only impact the presentation of our financial statements. |

| Equity Method Investments | Equity Method Investments
We recognize our share of earnings or losses from these entities under the equity method on a two-month lag. Equity in net income (loss) of equity method investees, net of tax, included the following:
Our maximum exposure to loss from our involvement with our equity method investments that are VIEs was as follows:
The maximum exposure to loss primarily included our investment balance as well as related translation adjustments in accumulated other comprehensive income and receivables, if any. We may also incur losses in connection with our obligations under a supply agreement with Inotera. Through the second quarter of 2012, we had rights and obligations to purchase a portion of Inotera's wafer production capacity under the Inotera Supply Agreement. As a result of our March 2012 equity contribution to Inotera, our obligation to purchase Inotera's capacity may increase when additional output results from Inotera's capital investments enabled by our equity investment. Inotera We have partnered with Nanya in Inotera, a Taiwanese DRAM memory company. We acquired our initial ownership interest in Inotera in the first quarter of 2009. As of March 1, 2012, we held a 29.7% ownership interest in Inotera, Nanya held a 30.4% ownership interest and the remaining ownership interest was publicly held. The carrying value of our initial investment in Inotera was less than our proportionate share of its equity. This difference is being amortized as a credit to earnings through equity in net income (loss) of equity method investees (the "Inotera Amortization"). As of March 1, 2012, $50 million of Inotera Amortization remained to be recognized, of which $25 million is scheduled to be amortized in the remainder of 2012 with the remaining amount to be amortized through 2034. Because of significant market declines in the selling price of DRAM, Inotera incurred net losses of $737 million for its year ended December 31, 2011. Also, Inotera's current liabilities exceeded its current assets by $2.2 billion as of December 31, 2011, which exposes Inotera to liquidity risk. Inotera's management has developed plans to improve its liquidity. There can be no assurance that Inotera's plans to improve its liquidity will be successful. On December 20, 2011, we loaned $133 million to Inotera under a 90-day note with a stated annual interest rate of 2% to facilitate the purchase of capital equipment necessary to implement new process technology. The loan was repaid to us with accrued interest in March 2012, subsequent to the end of our second quarter of 2012. Also, in March 2012, subsequent to the end of our second quarter of 2012, we contributed $170 million to Inotera, which increased our ownership percentage from 29.7% to 39.7%. Through the second quarter of 2012, we had a supply agreement with Inotera, under which Nanya was also a party, for the rights and obligations to purchase 50% of Inotera's wafer production capacity (the "Inotera Supply Agreement"). As a result of our March 2012 equity contribution to Inotera, we expect to receive a higher share of Inotera's 30-nanometer output when it becomes available from Inotera capital investments enabled by our $170 million equity investment. Our cost of wafers purchased under the Inotera Supply Agreement is based on a margin-sharing formula among Nanya, Inotera, and us. Under such formula, all parties' manufacturing costs related to wafers supplied by Inotera, as well as our and Nanya's revenue for the resale of products from wafers supplied by Inotera, are considered in determining costs for wafers acquired from Inotera. Under the Inotera Supply Agreement, we purchased $142 million and $298 million of DRAM products in the second quarter and first six months of 2012, respectively, and $167 million and $304 million of DRAM products in the second quarter and first six months of 2011, respectively. In addition, under the Inotera Supply Agreement, we accrued a liability and recognized a loss on our purchase commitment of $19 million in the second quarter of 2012 and $40 million in the first quarter of 2012. As of March 1, 2012 and September 1, 2011, there were gains of $46 million and $65 million, respectively, in accumulated other comprehensive income (loss) for cumulative translation adjustments from our equity investment in Inotera. As of March 1, 2012, based on the closing trading price of Inotera's shares in an active market, the market value of our equity interest in Inotera was $404 million, which exceeded our net carrying value of $213 million. The net carrying value is our investment balance of $259 million less the cumulative translation adjustments in accumulated other comprehensive income (loss) of $46 million. Under a cost-sharing arrangement, we share equally in DRAM development costs with Nanya. As a result, our research and development ("R&D") costs were reduced by $36 million and $73 million for the second quarter and first six months of 2012, respectively, and $33 million and $63 million for the second quarter and first six months of 2011, respectively. In addition, we received $1 million and $4 million of royalty revenue for the second quarter and first six months of 2012, respectively, and $6 million and $13 million of royalty revenue for the second quarter and first six months of 2011, respectively, from Nanya for sales of stack DRAM products manufactured by or for Nanya on process nodes of 50nm or higher. Transform In the second quarter of 2010, we acquired a 50% interest in Transform, a developer, manufacturer and marketer of photovoltaic technology and solar panels, from Origin. As of March 1, 2012, we and Origin each held a 50% ownership interest in Transform. During the second quarter and first six months of 2012, we and Origin each contributed $4 million and $7 million, respectively, of cash to Transform, and for the second quarter and first six months of 2011, we and Origin each contributed $4 million and $11 million, respectively, of cash to Transform. Our results of operations for the second quarter and first six months of 2012 included $4 million and $8 million, respectively, of net sales, which approximated our cost, for transition services provided to Transform. For the second quarter and first six months of 2011, our results of operations included $6 million and $11 million, respectively, of net sales, which approximated our cost, for transition services provided to Transform. Other Included in other equity method investments is our 35% equity interest in Aptina. During the second quarter of 2012, the amount of cumulative loss we recognized from our investment in Aptina reduced our investment balance to zero and we ceased recognizing our proportionate share of Aptina's losses. We will resume recognizing our proportionate share of Aptina's earnings only when our proportionate share of their earnings exceeds the amount of cumulative net losses not recognized. We manufacture components for CMOS image sensors for Aptina under a wafer supply agreement. For the second quarter and first six months of 2012, we recognized net sales of $99 million and $193 million, respectively, from products sold to Aptina. For the second quarter and first six months of 2011, we recognized net sales of $82 million and $141 million, respectively, from products sold to Aptina. Revenue on our sales to Aptina approximated costs. |

In the second quarter of 2012, we received $230 million in proceeds from equipment sales-leaseback transactions and as a result recorded capital lease obligations aggregating $230 million at a weighted-average effective interest rate of 3.9%, payable in periodic installments through February 2016. In the first six months of 2012, we received $340 million in proceeds from equipment sales-leaseback transactions and as a result recorded capital lease obligations aggregating $340 million at a weighted-average effective interest rate of 4.0%, payable in periodic installments through February 2016. Debt Restructure In the first quarter of 2011, in connection with a series of debt restructure transactions with certain holders of our convertible notes, we recognized a loss of $111 million as follows:
Debt Redemption Notice On April 5, 2012, we provided the holders of our 2013 convertible senior notes written notice of redemption on June 4, 2012. The redemption price will equal the $139 million principal amount of the notes, plus accrued and unpaid interest and a "make-whole premium" equal to the present value of the remaining scheduled interest payments on the notes from the redemption to maturity (October 15, 2013). The conversion rate for these notes is 196.7052 shares of common stock per $1,000 principal amount (approximately $5.08 per share) and up to 27.3 million shares may be issued if some or all of the holders elect to convert their notes to shares. |

| Notes to Financial Statements [Abstract] | |
| Contingencies | Contingencies We have accrued a liability and charged operations for the estimated costs of adjudication or settlement of various asserted and unasserted claims existing as of the balance sheet date, including those described below. We are currently a party to other legal actions arising from the normal course of business, none of which is expected to have a material adverse effect on our business, results of operations or financial condition. Patent Matters As is typical in the semiconductor and other high technology industries, from time to time, others have asserted, and may in the future assert, that our products or manufacturing processes infringe their intellectual property rights. We are engaged in litigation with Rambus, Inc. ("Rambus") relating to certain of Rambus' patents and certain of our claims and defenses. Our lawsuits with Rambus are pending in the U.S. District Court for the District of Delaware, U.S. District Court for the Northern District of California, Germany, France, and Italy. On August 28, 2000, we filed a complaint against Rambus in the U.S. District Court for the District of Delaware seeking declaratory and injunctive relief. The complaint alleges, among other things, various anticompetitive activities and also seeks a declaratory judgment that certain Rambus patents are invalid and/or unenforceable. Rambus subsequently filed an answer and counterclaim in Delaware alleging, among other things, infringement of twelve Rambus patents and seeking monetary damages and injunctive relief. We subsequently added claims and defenses based on Rambus' alleged spoliation of evidence and litigation misconduct. The spoliation and litigation misconduct claims and defenses were heard in a bench trial before Judge Robinson in October 2007. On January 9, 2009, Judge Robinson entered an opinion in our favor holding that Rambus had engaged in spoliation and that the twelve Rambus patents in the suit were unenforceable against us. Rambus subsequently appealed the decision to the U.S. Court of Appeals for the Federal Circuit. On May 13, 2011, the Federal Circuit affirmed Judge Robinson's finding of spoliation, but vacated the dismissal sanction and remanded the case to the Delaware District Court for analysis of the remedy based on the Federal Circuit's decision. On January 13, 2006, Rambus filed a lawsuit against us in the U.S. District Court for the Northern District of California alleging that certain of our DDR2, DDR3, RLDRAM and RLDRAM II products infringe as many as fourteen Rambus patents and seeking monetary damages, treble damages, and injunctive relief. The Northern District of California Court stayed the trial of the patent phase of the Northern District of California case upon appeal of the Delaware spoliation issue to the Federal Circuit. On March 6, 2009, Panavision Imaging, LLC filed suit against us and Aptina Imaging Corporation, then a wholly-owned subsidiary, in the U.S. District Court for the Central District of California. The complaint alleged that certain of our and Aptina's image sensor products infringed four Panavision Imaging U.S. patents and sought injunctive relief, damages, attorneys' fees, and costs. On February 7, 2011, the Court ruled that one of the four patents in suit was invalid for indefiniteness. On March 10, 2011, claims relating to the remaining three patents in suit were dismissed with prejudice. Panavision subsequently filed a motion for reconsideration of the Court's decision regarding invalidity of the first patent, and we filed a motion for summary judgment of non-infringement of such patent. On July 8, 2011, the Court issued an order that rescinded its prior indefiniteness decision, and held that the disputed term does not render the claims in suit indefinite. On February 3, 2012, the Court granted our motion for summary judgment of non-infringement. On March 20, 2012, we executed a settlement agreement with Panavision pursuant to which the parties agreed to a settlement and release of all claims and a dismissal with prejudice of the litigation, which did not have a material effect on our business, results of operations or financial condition. On September 1, 2011, HSM Portfolio LLC and Technology Properties Limited LLC filed a patent infringement action in the U.S. District Court for the District of Delaware against us and seventeen other defendants. The complaint alleges that certain of our DRAM and image sensor products infringe two U.S. patents and seeks injunctive relief, damages, attorneys' fees, and costs. On September 9, 2011, Advanced Data Access LLC filed a patent infringement action in the U.S. District Court for the Eastern District of Texas against us and seven other defendants. On November 16, 2011, Advanced Data Access filed an amended complaint. The amended complaint alleges that certain of our DRAM products infringe two U.S. patents and seeks injunctive relief, damages, attorneys' fees, and costs. On September 14, 2011, Smart Memory Solutions LLC filed a patent infringement action in the U.S. District Court for the District of Delaware against us and Winbond Electronics Corporation of America. The complaint alleges that certain of our NOR Flash products infringe a single U.S. patent and seeks injunctive relief, damages, attorneys' fees, and costs. On December 5, 2011, the Board of Trustees for the University of Illinois filed a patent infringement action against us in the U.S. District Court for the Central District of Illinois. The complaint alleges that unspecified semiconductor products of ours infringe three U.S. patents and seeks injunctive relief, damages, attorneys' fees, and costs. On March 26, 2012, Semiconductor Technologies, LLC filed a patent infringement action in the U.S. District Court for the Eastern District of Texas (Marshall) against us. The complaint alleges that certain of our DRAM products infringe five U.S. patents and seeks injunctive relief, damages, attorneys' fees, and costs. Among other things, the above lawsuits pertain to certain of our SDRAM, DDR SDRAM, DDR2 SDRAM, DDR3 SDRAM, RLDRAM, NOR Flash and image sensor products, which account for a significant portion of our net sales. We are unable to predict the outcome of assertions of infringement made against us and therefore cannot estimate the range of possible loss. A court determination that our products or manufacturing processes infringe the intellectual property rights of others could result in significant liability and/or require us to make material changes to our products and/or manufacturing processes. Any of the foregoing could have a material adverse effect on our business, results of operations or financial condition. Antitrust Matters On May 5, 2004, Rambus filed a complaint in the Superior Court of the State of California (San Francisco County) against us and other DRAM suppliers which alleged that the defendants harmed Rambus by engaging in concerted and unlawful efforts affecting Rambus DRAM ("RDRAM") by eliminating competition and stifling innovation in the market for computer memory technology and computer memory chips. Rambus' complaint alleged various causes of action under California state law including, among other things, a conspiracy to restrict output and fix prices, a conspiracy to monopolize, intentional interference with prospective economic advantage, and unfair competition. Rambus sought a judgment for damages of approximately $3.9 billion, joint and several liability, trebling of damages awarded, punitive damages, a permanent injunction enjoining the defendants from the conduct alleged in the complaint, interest, and attorneys' fees and costs. Trial began on June 20, 2011, and the case went to the jury on September 21, 2011. On November 16, 2011, the jury found for us on all claims. On April 2, 2012, Rambus filed a notice of appeal with the Superior Court. At least sixty-eight purported class action price-fixing lawsuits have been filed against us and other DRAM suppliers in various federal and state courts in the United States and in Puerto Rico on behalf of indirect purchasers alleging a conspiracy to increase DRAM prices in violation of federal and state antitrust laws and state unfair competition law, and/or unjust enrichment relating to the sale and pricing of DRAM products during the period from April 1999 through at least June 2002. The complaints seek joint and several damages, trebled, in addition to restitution, costs and attorneys' fees. A number of these cases have been removed to federal court and transferred to the U.S. District Court for the Northern District of California for consolidated pre-trial proceedings. In July, 2006, the Attorneys General for approximately forty U.S. states and territories filed suit in the U.S. District Court for the Northern District of California. The complaints allege, among other things, violations of the Sherman Act, Cartwright Act, and certain other states' consumer protection and antitrust laws and seek joint and several damages, trebled, as well as injunctive and other relief. On October 3, 2008, the California Attorney General filed a similar lawsuit in California Superior Court, purportedly on behalf of local California government entities, alleging, among other things, violations of the Cartwright Act and state unfair competition law. On June 23, 2010, we executed a settlement agreement resolving these purported class-action indirect purchaser cases and the pending cases of the Attorneys General relating to alleged DRAM price-fixing in the United States. Subject to certain conditions, including final court approval of the class settlements, we agreed to pay approximately $67 million in aggregate in three equal installments over a two-year period. As of March 1, 2012, we have paid $45 million into an escrow account in accordance with the settlement agreement. Three putative class action lawsuits alleging price-fixing of DRAM products also have been filed against us in Quebec, Ontario, and British Columbia, Canada, on behalf of direct and indirect purchasers, asserting violations of the Canadian Competition Act and other common law claims. The claims were initiated between December 2004 (British Columbia) and June 2006 (Quebec). The plaintiffs seek monetary damages, restitution, costs, and attorneys' fees. The substantive allegations in these cases are similar to those asserted in the DRAM antitrust cases filed in the United States. Plaintiffs' motion for class certification was denied in the British Columbia and Quebec cases in May and June 2008, respectively. Plaintiffs subsequently filed an appeal of each of those decisions. On November 12, 2009, the British Columbia Court of Appeal reversed, and on November 16, 2011, the Quebec Court of Appeal also reversed the denial of class certification and remanded the cases for further proceedings. On June 21, 2010, the Brazil Secretariat of Economic Law of the Ministry of Justice ("SDE") announced that it had initiated an investigation relating to alleged anticompetitive activities within the DRAM industry. The SDE's Notice of Investigation names various DRAM manufacturers and certain executives, including us, and focuses on the period from July 1998 to June 2002. On September 24, 2010, Oracle America Inc. ("Oracle"), successor to Sun Microsystems, a DRAM purchaser that opted-out of a direct purchaser class action suit that was settled, filed suit against us in U.S. District Court for the Northern District of California. The complaint alleged a conspiracy to increase DRAM prices and other violations of federal and state antitrust and unfair competition laws based on purported conduct for the period from August 1, 1998 through at least June 15, 2002. Oracle sought joint and several damages, trebled, as well as restitution, disgorgement, attorneys' fees, costs and injunctive relief. On March 23, 2012, we entered into a settlement agreement with Oracle pursuant to which we agreed to make a payment of $58 million to Oracle for a settlement and full release of all claims and a dismissal with prejudice of the litigation. We are unable to predict the outcome of these matters and therefore cannot estimate the range of possible loss, except as noted in the U.S. indirect purchasers cases and Oracle above. The final resolution of these alleged violations of antitrust laws could result in significant liability and could have a material adverse effect on our business, results of operations or financial condition. Commercial Matters On January 20, 2011, Dr. Michael Jaffé, administrator for Qimonda AG ("Qimonda") insolvency proceedings, filed suit against us and Micron Semiconductor B.V., our Netherlands subsidiary, in the District Court of Munich, Civil Chamber. The complaint seeks to void under Section 133 of the German Insolvency Act a share purchase agreement between us and Qimonda in fall 2008 pursuant to which we purchased all of Qimonda's shares of Inotera Memories, Inc. and seeks an order requiring us to retransfer the Inotera shares to the Qimonda estate. The complaint also seeks to terminate under Sections 103 or 133 of the German Insolvency Code a patent cross license between us and Qimonda entered into at the same time as the share purchase agreement. A hearing scheduled to begin on November 9, 2011 was continued and has not yet been rescheduled. We are unable to predict the outcome of this lawsuit and therefore cannot estimate the range of possible loss. The final resolution of this lawsuit could result in the loss of the Inotera shares or equivalent monetary damages and the termination of the patent cross license, which could have a material adverse effect on our business, results of operation or financial condition. In the normal course of business, we are a party to a variety of agreements pursuant to which we may be obligated to indemnify the other party. It is not possible to predict the maximum potential amount of future payments under these types of agreements due to the conditional nature of our obligations and the unique facts and circumstances involved in each particular agreement. Historically, our payments under these types of agreements have not had a material adverse effect on our business, results of operations or financial condition. |

| Derivative Financial Instruments | Derivative Financial Instruments We are exposed to currency exchange rate risk for monetary assets and liabilities held or denominated in foreign currencies, primarily the euro, shekel, Singapore dollar and yen. We are also exposed to currency exchange rate risk for capital expenditures, primarily denominated in the euro and yen. We use derivative instruments to manage our exposures to changes in currency exchange rates. For exposures associated with our monetary assets and liabilities, our primary objective in entering into currency derivatives is to reduce the volatility that changes in currency exchange rates have on our earnings. For exposures associated with capital expenditures, our primary objective in entering into currency derivatives is to reduce the volatility that changes in currency exchange rates have on future cash flows. Our derivatives consist primarily of currency forward contracts. The derivatives expose us to credit risk to the extent the counterparties may be unable to meet the terms of the derivative instrument. Our maximum exposure to loss due to credit risk that we would incur if parties to forward contracts failed completely to perform according to the terms of the contracts was equal to our carrying value of the forward contracts as of March 1, 2012, as listed in the tables below under asset fair values. We seek to mitigate such risk by limiting our counterparties to major financial institutions and by spreading risk across multiple major financial institutions. In addition, we monitor the potential risk of loss with any one counterparty resulting from this type of credit risk on an ongoing basis. We have the following currency risk management programs: Currency Derivatives without Hedge Accounting Designation We utilize a rolling hedge strategy with currency forward contracts that generally mature within 35 days to hedge our exposure to changes in currency exchange rates. At the end of each reporting period, monetary assets and liabilities held or denominated in currencies other than the U.S. dollar are remeasured in U.S. dollars and the associated outstanding forward contracts are marked-to-market. Currency forward contracts are valued at fair values based on bid prices of dealers or exchange quotations (referred to as Level 2). Realized and unrealized gains and losses on derivative instruments and the underlying monetary assets and liabilities are included in other operating income (expense). Total gross notional amounts and fair values for currency derivatives without hedge accounting designation were as follows:
For currency forward contracts without hedge accounting designation, we recognized gains of $3 million and losses of $17 million for the second quarter and first six months of 2012, respectively, and gains of $7 million and $5 million for the second quarter and first six months of 2011, respectively, which were included in other operating income (expense). Currency Derivatives with Cash Flow Hedge Accounting Designation We utilize currency forward contracts that generally mature within 12 months to hedge the exposure of changes in cash flows from changes in currency exchange rates for certain forecasted capital expenditures. Currency forward contracts are valued at their fair values based on market-based observable inputs including currency exchange spot and forward rates, interest rate and credit risk spread (referred to as Level 2). For those derivatives designated as cash flow hedges, the effective portion of the realized and unrealized gain or loss on the derivatives was included as a component of accumulated other comprehensive income (loss) in shareholders' equity. The amounts in accumulated other comprehensive income (loss) for those cash flow hedges are reclassified into earnings in the same line items of the consolidated statements of operations and in the same periods in which the underlying transactions affect earnings. The ineffective or excluded portion of the realized and unrealized gain or loss is included in other operating income (expense). Total gross notional amounts and fair values for currency derivatives with cash flow hedge accounting designation were as follows:
For the second quarter and first six months of 2012, we recognized $2 million and $11 million, respectively, of net derivative losses in other comprehensive income from the effective portion of cash flow hedges. For the second quarter and first six months of 2011, we recognized $22 million and $28 million, respectively, of net derivative gains in other comprehensive income from the effective portion of cash flow hedges. The ineffective and excluded portions of cash flow hedges recognized in other operating income (expense) were not significant in the second quarters and first six months of 2012 and 2011. Amounts in accumulated other comprehensive income are amortized to manufacturing cost over the useful life of the underlying hedged equipment and reclassified to earnings when inventory is sold. In the second quarter and first six months of 2012, $2 million and $4 million, respectively, of net gains was reclassified from other comprehensive income (loss) to earnings and the amount of net derivative gains included in other accumulated comprehensive income (loss) expected to be reclassified into earnings in the next 12 months was $6 million as of March 1, 2012. |
