The consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States (U.S. GAAP). The basis of these financial statements is comparable for all periods presented herein.

The consolidated financial statements include the accounts of all subsidiaries. All intercompany balances and transactions have been eliminated in consolidation. All dollar amounts in the financial statements and tables in these notes, except per-share amounts, are stated in millions of U.S. dollars unless otherwise indicated. We have reclassified certain amounts in the prior periods’ financial statements to conform to the 2011 presentation. The preparation of financial statements requires the use of estimates from which final results may vary.

On September 23, 2011, we completed the acquisition of National. The consolidated financial statements include the balances and results of operations of National from the date of acquisition. See Note 2 for more detailed information.

Revenue recognition

We recognize revenue from direct sales of our products to our customers, including shipping fees, when title passes to the customer, which usually occurs upon shipment or delivery, depending upon the terms of the sales order; when persuasive evidence of an arrangement exists; when sales amounts are fixed or determinable; and when collectability is reasonably assured. Revenue from sales of our products that are subject to inventory consignment agreements is recognized when the customer pulls product from consignment inventory that we store at designated locations. Estimates of product returns for quality reasons and of price allowances (based on historical experience, product shipment analysis and customer contractual arrangements) are recorded when revenue is recognized. Allowances include volume-based incentives and special pricing arrangements. In addition, we record allowances for accounts receivable that we estimate may not be collected.

We recognize revenue from direct sales of our products to our distributors, net of allowances, consistent with the principles discussed above. Title transfers to the distributors at delivery or when the products are pulled from consignment inventory, and payment is due on our standard commercial terms; payment terms are not contingent upon resale of the products. We also grant discounts to some distributors for prompt payments. We calculate credit allowances based on historical data, current economic conditions and contractual terms. For instance, we sell to distributors at standard published prices, but we may grant them price adjustment credits in response to individual competitive opportunities they may have. To estimate allowances, we use statistical percentages of revenue, determined quarterly, based upon recent historical adjustment trends.

We also provide distributors an allowance to scrap certain slow-moving or obsolete products in their inventory, estimated as a negotiated fixed percentage of each distributor’s purchases from us. In addition, if we publish a new price for a product that is lower than that paid by distributors for the same product still remaining in each distributor’s on-hand inventory, we may credit them for the difference between those prices. The allowance for this type of credit is based on the identified product price difference applied to our estimate of each distributor’s on-hand inventory of that product. We believe we can reasonably and reliably estimate allowances for credits to distributors in a timely manner.

We determine the amount and timing of royalty revenue based on our contractual agreements with intellectual property licensees. We recognize royalty revenue when earned under the terms of the agreements and when we consider realization of payment to be probable. Where royalties are based on a percentage of licensee sales of royalty-bearing products, we recognize royalty revenue by applying this percentage to our estimate of applicable licensee sales. We base this estimate on historical experience and an analysis of each licensee’s sales results. Where royalties are based on fixed payment amounts, we recognize royalty revenue ratably over the term of the royalty agreement. Where warranted, revenue from licensees may be recognized on a cash basis.

We include shipping and handling costs in COR.

Advertising costs

We expense advertising and other promotional costs as incurred. This expense was $43 million in 2011, $44 million in 2010 and $42 million in 2009.

Income taxes

We account for income taxes using an asset and liability approach. We record the amount of taxes payable or refundable for the current year and the deferred tax assets and liabilities for future tax consequences of events that have been recognized in the financial statements or tax returns. We record a valuation allowance when it is more likely than not that some portion or all of the deferred tax assets will not be realized.

Other assessed taxes

Some transactions require us to collect taxes such as sales, value-added and excise taxes from our customers. These transactions are presented in our statements of income on a net (excluded from revenue) basis.

Earnings per share (EPS)

Unvested awards of share-based payments with rights to receive dividends or dividend equivalents, such as our restricted stock units (RSUs), are considered to be participating securities and the two-class method is used for purposes of calculating EPS. Under the two-class method, a portion of net income is allocated to these participating securities and, therefore, is excluded from the calculation of EPS allocated to common stock, as shown in the table below.

Computation and reconciliation of earnings per common share are as follows (shares in millions):



	2011						2010						2009
	Net Income			Shares	EPS		Net Income			Shares	EPS		Net Income			Shares	EPS
Basic EPS:
Net income	$	2,236					$	3,228					$	1,470
Less income allocated to RSUs	(35		)				(44		)				(14		)
Income allocated to common stock for basic EPS calculation	$	2,201		1,151	$	1.91	$	3,184		1,199	$	2.66	$	1,456		1,260	$	1.16

Adjustment for dilutive shares:
Stock-based compensation plans				20						14						9

Diluted EPS:
Net income	$	2,236					$	3,228					$	1,470
Less income allocated to RSUs	(34		)				(44		)				(14		)
Income allocated to common stock for diluted EPS calculation	$	2,202		1,171	$	1.88	$	3,184		1,213	$	2.62	$	1,456		1,269	$	1.15

Options to purchase 41 million, 88 million and 135 million shares of common stock that were outstanding during 2011, 2010 and 2009, respectively, were not included in the computation of diluted EPS because their exercise price was greater than the average market price of the common shares and, therefore, the effect would be anti-dilutive.

Investments

We present investments on our balance sheets as cash equivalents, short-term investments or long-term investments. Specific details are as follows:

Cash equivalents and short-term investments: We consider investments in debt securities with maturities of three months or less from the date of our investment to be cash equivalents. We consider investments in debt securities with maturities beyond three months from the date of our investment as being available for use in current operations and include these investments in short-term investments. The primary objectives of our cash equivalent and short-term investment activities are to preserve capital and maintain liquidity while generating appropriate returns.

Long-term investments: Long-term investments consist of mutual funds, auction-rate securities, venture capital funds and non-marketable equity securities.

Classification of investments: Depending on our reasons for holding the investment and our ownership percentage, we classify investments in securities as available for sale, trading, equity-method or cost-method investments, which are more fully described in Note 9. We determine cost or amortized cost, as appropriate, on a specific identification basis.

Inventories

Inventories are stated at the lower of cost or estimated net realizable value. Cost is generally computed on a currently adjusted standard cost basis, which approximates cost on a first-in first-out basis. Standard cost is based on the normal utilization of installed factory capacity. Cost associated with underutilization of capacity is expensed as incurred. Inventory held at consignment locations is included in our finished goods inventory. Consigned inventory was $129 million and $130 million as of December 31, 2011 and 2010, respectively.

We review inventory quarterly for salability and obsolescence. A specific allowance is provided for inventory considered unlikely to be sold. Remaining inventory includes a salability and obsolescence allowance based on an analysis of historical disposal activity. We write off inventory in the period in which disposal occurs.

Property, plant and equipment; acquisition-related intangibles and other capitalized costs

Property, plant and equipment are stated at cost and depreciated over their estimated useful lives using the straight-line method. Our cost basis includes certain assets acquired in business combinations that were initially recorded at fair value as of the date of acquisition. Leasehold improvements are amortized using the straight-line method over the shorter of the remaining lease term or the estimated useful lives of the improvements. We amortize acquisition-related intangibles on a straight-line basis over the estimated economic life of the assets. Capitalized software licenses generally are amortized on a straight-line basis over the term of the license. Fully depreciated or amortized assets are written off against accumulated depreciation or amortization.

Impairments of long-lived assets

We regularly review whether facts or circumstances exist that indicate the carrying values of property, plant and equipment or other long-lived assets, including intangible assets, are impaired. We assess the recoverability of assets by comparing the projected undiscounted net cash flows associated with those assets to their respective carrying amounts. Any impairment charge is based on the excess of the carrying amount over the fair value of those assets. Fair value is determined by available market valuations, if applicable, or by discounted cash flows.

Goodwill and indefinite-lived intangibles

Goodwill is not amortized but is reviewed for impairment annually or more frequently if certain impairment indicators arise. We complete our annual goodwill impairment tests as of October 1 for our reporting units. The test compares the fair value for each reporting unit to its associated carrying value including goodwill. We have had no impairment of goodwill for 2011 or 2010.

Foreign currency

The functional currency for our non-U.S. subsidiaries is the U.S. dollar. Accounts recorded in currencies other than the U.S. dollar are remeasured into the functional currency. Current assets (except inventories), deferred income taxes, other assets, current liabilities and long-term liabilities are remeasured at exchange rates in effect at the end of each reporting period. Property, plant and equipment with associated depreciation and inventories are remeasured at historic exchange rates. Revenue and expense accounts other than depreciation for each month are remeasured at the appropriate daily rate of exchange. Currency exchange gains and losses from remeasurement are credited or charged to OI&E.

Derivatives and hedging

In connection with the issuance of variable-rate long-term debt in May 2011, as more fully described in Note 13, we entered into an interest rate swap designated as a hedge of the variability of cash flows related to interest payments. Gains and losses from changes in the fair value of the interest rate swap are credited or charged to Accumulated other comprehensive income (loss), net of taxes (AOCI).

We also use derivative financial instruments to manage exposure to foreign exchange risk. These instruments are primarily forward foreign currency exchange contracts that are used as economic hedges to reduce the earnings impact exchange rate fluctuations may have on our non-U.S. dollar net balance sheet exposures or for specified non-U.S. dollar forecasted transactions. Gains and losses from changes in the fair value of these forward foreign currency exchange contracts are credited or charged to OI&E. We do not apply hedge accounting to our foreign currency derivative instruments.

We do not use derivatives for speculative or trading purposes.

Changes in accounting standards

In May 2011, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) No. 2011-04, Fair Value Measurement (Topic 820): Amendments to Achieve Common Fair Value Measurement and Disclosure Requirements in U.S. GAAP and IFRS. This standard results in a common requirement between the FASB and the International Accounting Standards Board (IASB) for measuring fair value and for disclosing information about fair-value measurements. While this new standard will not affect how we measure or account for assets and liabilities at fair value, disclosures will be required for interim and annual periods beginning January 1, 2012. There will be no impact to our financial condition or results of operation from the adoption of this new standard.

In September 2011, the FASB issued ASU No. 2011-08, Intangibles – Goodwill and Other (Topic 350): Testing Goodwill for Impairment. This standard is intended to simplify how we will test goodwill for impairment. Prior to the issuance of this standard, we were required to use a two-step quantitative test to assess impairment of goodwill. Under this new standard, we will have the option to first assess qualitative factors to determine whether that two-step quantitative test should be performed. This standard is effective for goodwill impairment tests performed for fiscal years beginning after December 15, 2011, with early adoption permitted. We will adopt this standard effective January 1, 2012.

National Semiconductor acquisition

12 Months Ended

Dec. 31, 2011

National [Member]

Business Acquisition [Line Items]

National Semiconductor acquisition

On September 23, 2011, we completed the acquisition of National by acquiring all issued and outstanding common shares in exchange for cash. National designed, developed, manufactured and marketed a wide range of semiconductor products, focused on providing high-performance energy-efficient analog and mixed-signal solutions. The purpose of the acquisition was to grow revenue by combining National’s products with TI’s larger sales force and customer base.

We accounted for this transaction under Accounting Standards Codification (ASC) 805 - Business Combinations, and National’s operating results are included in the Analog segment from the acquisition date as SVA.

The acquisition-date fair value of the consideration transferred is as follows:



Cash payments	$	6,535
Fair value of vested share-based awards assumed by TI	22
Total consideration transferred to National shareholders	$	6,557

We prepared an initial determination of the fair value of assets acquired and liabilities assumed as of the acquisition date using preliminary information. Adjustments were made during the fourth quarter of 2011 to the fair value of assets acquired and liabilities assumed, as a result of refining our estimates. These were retrospectively applied to the September 23, 2011, acquisition date balance sheet. These adjustments are primarily related to tax matters and netted to an increase of goodwill of $1 million. None of the adjustments had a material impact on TI’s previously reported results of operations.

As of December 31, 2011, the allocation of the consideration transferred to the assets acquired and liabilities assumed from National has been finalized. The determination of fair value reflects the assistance of third-party valuation specialists, as well as our own estimates and assumptions. The final allocation of fair value by major class of the assets acquired and liabilities assumed as of the acquisition date is as follows:



	At September 23, 2011
Cash and cash equivalents	$	1,145
Current assets	451
Inventory	225
Property, plant and equipment	865
Other assets	138
Acquired intangible assets (see details below)	2,956
Goodwill	3,528
Assumed current liabilities	(191		)
Assumed long-term debt	(1,105		)
Deferred taxes and other assumed non-current liabilities	(1,455		)
Total consideration transferred	$	6,557

Identifiable intangible assets acquired and their estimated useful lives as of the acquisition date are as follows:



	Asset Amount		Weighted Average Useful Life (Years)
Developed technology	$	2,025	10
Customer relationships	810		8
Other	16		3
Identified intangible assets subject to amortization	2,851
In-process R&D	105		(a)
Total identified intangible assets	$	2,956

(a) In-process R&D is not amortized until the associated project has been completed. Alternatively, if the associated project is determined not to be viable, it will be expensed.

The remaining consideration, after adjusting for identified intangible assets and the net assets and liabilities recorded at fair value, was $3.528 billion and was applied to goodwill. Goodwill is attributed to National’s product portfolio and workforce expertise. None of the goodwill related to the National acquisition is deductible for tax purposes.

We assumed $1.0 billion of outstanding debt as a result of our acquisition of National and recorded it at its fair value of $1.105 billion. The excess of the fair value over the stated value is amortized as a reduction to Interest and debt expense over the term of the debt. In 2011, we recognized $9 million related to the amortization of the excess fair value.

The amount of National’s revenue included in our Consolidated statements of income for the period from the acquisition date to December 31, 2011, was $312 million. We do not measure net income at or below our segment levels.

The following unaudited summaries of pro forma combined results of operation for the years ended December 31, 2011 and 2010, give effect to the acquisition as if it had been completed on January 1, 2010. These pro forma summaries do not reflect any operating efficiencies, cost savings or revenue enhancements that may be achieved by the combined companies. In addition, certain non-recurring expenses, such as restructuring charges and retention bonuses that will be incurred within the first 12 months after the acquisition, are not reflected in the pro forma summaries. These pro forma summaries are presented for informational purposes only and are not necessarily indicative of what the actual results of operations would have been had the acquisition taken place as of that date, nor are they indicative of future consolidated results of operations.



	For Years Ended December 31,
	2011		2010
	(unaudited)
Revenue	$	14,805	$	15,529
Net income	2,438		3,218
Earnings per common share – diluted	2.05		2.61

Acquisition-related charges

We incurred various costs as a result of the acquisition of National that are included in Other consistent with how management measures the performance of its segments. These total acquisition-related charges are as follows:



	For Year Ended December 31, 2011
Inventory related	$	96
Property, plant and equipment related	15
As recorded in COR	111
Amortization of intangible assets	87
Severance and other benefits:
Change of control	41
Announced employment reductions	29
Stock-based compensation	50
Transaction costs	48
Retention bonuses	46
Other	14
As recorded in Acquisition charges/divestiture (gain)	315
Total acquisition-related charges	$	426

We recognized costs associated with the adjustments to write up the value of acquired inventory and property, plant and equipment to fair value as of the acquisition date. These costs are in addition to the normal expensing of the acquired assets based on their carrying or book value prior to the acquisition. The total fair-value write-up for the acquired inventory was expensed as that inventory was sold. The total fair-value write-up for the acquired property, plant and equipment was $436 million, which is being depreciated at a rate of about $15 million per quarter beginning in the fourth quarter of 2011.

The amount of recognized amortization of acquired intangible assets resulting from the National acquisition was $87 million for the period from the acquisition date to December 31, 2011. Amortization of intangible assets is based on estimated useful lives varying between two and ten years.

Severance and other benefits costs relate to former National employees who have been or will be terminated after the closing date. These costs total $70 million for the year ended December 31, 2011, with $41 million in charges related to change of control provisions under existing employment agreements and $29 million in charges for announced employment reductions affecting about 350 jobs. All of these jobs will be eliminated by the end of 2012 as a result of redundancies and cost efficiency measures, with approximately $20 million of additional expense to be recognized in 2012. Of the $70 million in charges recognized, $14 million was paid in 2011. The remaining $56 million will be paid in 2012.

Stock-based compensation of $50 million was recognized for the accelerated vesting of equity awards upon the termination of employees. Additional stock-based compensation will be recognized over any remaining service periods.

Transaction costs include expenses incurred in connection with the National acquisition, such as investment advisory, legal, accounting and printing fees, as well as bridge financing costs incurred in April 2011.

Retention bonuses reflect amounts expected to be paid to former National employees who fulfill agreed-upon service period obligations and will be recognized ratably over the required service period.

Losses associated with the earthquake in Japan	12 Months Ended
Losses associated with the earthquake in Japan	Dec. 31, 2011
Losses Associated with the events in Japan [Abstract]
Losses associated with the earthquake in Japan	Losses associated with the earthquake in Japan On March 11, 2011, a magnitude 9.0 earthquake struck near two of our three semiconductor manufacturing facilities in Japan. Our manufacturing site in Miho suffered substantial damage during the earthquake, our facility in Aizu experienced significantly less damage and our site in Hiji was undamaged. We maintain earthquake insurance policies in Japan for limited coverage for property damage and business interruption losses. Assessment and recovery efforts began immediately at these facilities and officially ended in August. Our Aizu factory recovered first and has been in production since the second quarter, while our Miho factory opened a mini-line for products in mid-April and was back to full production in the third quarter of 2011. During the year ended December 31, 2011, we incurred gross operating losses of $101 million related to property damage, the underutilization expense we incurred from having our manufacturing assets only partially loaded and costs associated with recovery teams assembled from across the world. These losses have been offset by about $23 million in insurance proceeds related to property damage claims. Almost all of these costs and proceeds are included in COR in the Consolidated statements of income and are recorded in Other. In addition to the costs associated with the earthquake, we also had an impact to revenue. For the year 2011, we recognized $38 million in insurance proceeds related to business interruption claims. These proceeds were recorded as revenue in Other. We continue to be in discussions with our insurers and their advisors, but at this time we cannot estimate the timing and amount of future proceeds we may ultimately receive from our policies.

Restructuring charges

12 Months Ended

Dec. 31, 2011

Restructuring and Related Activities [Abstract]

Restructuring charges

Restructuring charges may consist of voluntary or involuntary severance-related charges, asset-related charges and other costs to exit activities. We recognize voluntary termination benefits when the employee accepts the offered benefit arrangement. We recognize involuntary severance-related charges depending on whether the termination benefits are provided under an ongoing benefit arrangement or under a one-time benefit arrangement. If the former, we recognize the charges once they are probable and the amounts are estimable. If the latter, we recognize the charges once the benefits have been communicated to employees.

Restructuring activities associated with assets would be recorded as an adjustment to the basis of the asset, not as a liability. When we commit to a plan to abandon a long-lived asset before the end of its previously estimated useful life, we accelerate the recognition of depreciation to reflect the use of the asset over its shortened useful life. When an asset is held to be sold, we write down the carrying value to its net realizable value and cease depreciation.

Restructuring actions related to the acquisition of National are discussed in Note 2 above and are reflected on the Acquisition charges/divestiture (gain) line of our Consolidated statements of income.

2011 actions

In the fourth quarter of 2011, we recognized restructuring charges associated with the announced plans to close two older semiconductor manufacturing facilities in Hiji, Japan, and Houston, Texas, over the next 18 months. Combined, these facilities supported about 4 percent of TI’s revenue in 2011, and each employs about 500 people. As needed, production from these facilities will be moved to other more advanced TI factories. The total charge for these closures is estimated at $215 million, of which $112 million was recognized in the fourth quarter and the remainder will be incurred over the next seven quarters. The Restructuring charges recognized in the fourth quarter of 2011 are included in Other and consisted of $107 million for severance and benefit costs and $5 million of accelerated depreciation of the facilities’ assets. Of the estimated $215 million total cost, about $135 million will be for severance and related benefits, about $30 million will be for accelerated depreciation of facility assets and about $50 million will be for other exit costs.

Previous actions

In October 2008, we announced actions to reduce expenses in our Wireless segment, especially our baseband operation. In January 2009, we announced actions that included broad-based employment reductions to align our spending with weakened demand. Combined, these actions eliminated about 3,900 jobs; they were completed in 2009.

The table below reflects the changes in accrued restructuring balances associated with these actions:

Stock-based compensation

12 Months Ended

Dec. 31, 2011

Share-based Compensation [Abstract]

Stock-based compensation

We have stock options outstanding to participants under various long-term incentive plans. We also have assumed stock options that were granted by companies that we later acquired, including National. Unless the options are acquisition-related replacement options, the option price per share may not be less than 100 percent of the fair market value of our common stock on the date of the grant. Substantially all the options have a ten-year term and vest ratably over four years. Our options generally continue to vest after the option recipient retires.

We also have restricted stock units (RSUs) outstanding under the long-term incentive plans. Each RSU represents the right to receive one share of TI common stock on the vesting date, which is generally four years after the date of grant. Upon vesting, the shares are issued without payment by the grantee. RSUs generally do not continue to vest after the recipient’s retirement date.

We have options and RSUs outstanding to non-employee directors under various director compensation plans. The plans generally provide for annual grants of stock options and RSUs, a one-time grant of RSUs to each new non-employee director and the issuance of TI common stock upon the distribution of stock units credited to deferred compensation accounts established for such directors.

We also have an employee stock purchase plan under which options are offered to all eligible employees in amounts based on a percentage of the employee’s compensation. Under the plan, the option price per share is 85 percent of the fair market value on the exercise date, and options have a three-month term.

Total stock-based compensation expense recognized was as follows:



	2011		2010		2009
Stock-based compensation expense recognized in:
Cost of revenue (COR)	$	40	$	36	$	35
Research and development (R&D)	58		53		54
Selling, general and administrative (SG&A)	121		101		97
Acquisition charges	50		—		—
Total	$	269	$	190	$	186

These amounts include expense related to non-qualified stock options, RSUs and stock options offered under our employee stock purchase plan and are net of expected forfeitures.

We issue awards of non-qualified stock options generally with graded vesting provisions (e.g., 25 percent per year for four years). We recognize the related compensation cost on a straight-line basis over the minimum service period required for vesting of the award. For awards to employees who are retirement eligible or nearing retirement eligibility, we recognize compensation cost on a straight-line basis over the longer of the service period required to be performed by the employee in order to earn the award, or a six-month period.

Our RSUs generally vest four years after the date of grant. We recognize the related compensation costs on a straight-line basis over the vesting period.

National acquisition-related equity awards

In connection with the acquisition of National, we assumed certain stock options and RSUs granted by National, which were converted into the right to receive TI stock. The awards we assumed were measured at the acquisition date based on the

estimate of fair value, which was a total of $147 million. A portion of that fair value, $22 million, which represented the pre-combination vested service provided by employees to National, was included in the total consideration transferred as part of the acquisition. As of the acquisition date, the remaining portion of the fair value of those awards was $125 million, representing post-combination stock-based compensation expense that would be recognized as these employees provide service over the remaining vesting periods. At December 31, 2011, unrecognized compensation expense was $68 million.

Fair-value methods and assumptions

We account for all awards granted under our various stock-based compensation plans at fair value. We estimate the fair values for non-qualified stock options under long-term incentive and director compensation plans using the Black-Scholes option-pricing model with the following weighted average assumptions (these assumptions exclude options assumed in connection with the National acquisition):



	2011			2010			2009
Weighted average grant date fair value, per share	$	10.37		$	6.61		$	5.43
Weighted average assumptions used:
Expected volatility	30		%	32		%	48		%
Expected lives (in years)	6.9			6.4			5.9
Risk-free interest rates	2.61		%	2.83		%	2.63		%
Expected dividend yields	1.51		%	2.08		%	2.94		%

We determine expected volatility on all options granted after July 1, 2005, using available implied volatility rates. We believe that market-based measures of implied volatility are currently the best available indicators of the expected volatility used in these estimates.

We determine expected lives of options based on the historical option exercise experience of our optionees using a rolling ten-year average. We believe the historical experience method is the best estimate of future exercise patterns currently available.

Risk-free interest rates are determined using the implied yield currently available for zero-coupon U.S. government issues with a remaining term equal to the expected life of the options.

Expected dividend yields are based on the approved annual dividend rate in effect and the current market price of our common stock at the time of grant. No assumption for a future dividend rate change is included unless there is an approved plan to change the dividend in the near term.

The fair value per share of RSUs that we grant is determined based on the closing price of our common stock on the date of grant.

Our employee stock purchase plan is a discount-purchase plan and consequently the Black-Scholes option-pricing model is not used to determine the fair value per share of these awards. The fair value per share under this plan equals the amount of the discount.

Long-term incentive and director compensation plans

Stock option and RSU transactions under our long-term incentive and director compensation plans during 2011, including stock options and RSUs assumed in connection with the National acquisition, were as follows:



	Stock Options				RSUs

Outstanding grants, December 31, 2011	113,273,394		$	25.79	23,358,846		$	25.09

The weighted average grant-date fair value of RSUs granted during the years 2011, 2010 and 2009 was $33.20, $23.47 and $15.78 per share, respectively. For the years ended December 31, 2011, 2010 and 2009, the total fair value of shares vested from RSU grants was $155 million, $51 million and $28 million, respectively.

Summarized information about stock options outstanding at December 31, 2011, including options assumed in connection with the National acquisition, is as follows:



		Stock Options Outstanding				Options Exercisable

$	.26 to 38.40	113,273,394	4.5	$	25.79	82,234,319	$	25.97

During the years ended December 31, 2011, 2010 and 2009, the aggregate intrinsic value (i.e., the difference in the closing market price and the exercise price paid by the optionee) of options exercised was $231 million, $140 million and $21 million, respectively.

Summarized information as of December 31, 2011, about outstanding stock options that are vested and expected to vest, as well as stock options that are currently exercisable, is as follows:



	Outstanding Stock Options (Fully Vested and Expected to Vest) (a)		Options Exercisable
Number of outstanding (shares)	112,230,358		82,234,319
Weighted average remaining contractual life (in years)	4.5		3.2
Weighted average exercise price per share	$	26.03	$	25.97
Intrinsic value (millions of dollars)	$	539	$	370

(a) Includes effects of expected forfeitures of approximately 1 million shares. Excluding the effects of expected forfeitures, the aggregate intrinsic value of stock options outstanding was $543 million.

As of December 31, 2011, the total future compensation cost related to equity awards not yet recognized in the Consolidated statements of income was $477 million; $144 million related to unvested stock options and $333 million related to RSUs, of which $2 million and $66 million were associated with the National acquisition, respectively. The $477 million will be recognized as follows: $192 million in 2012, $153 million in 2013, $98 million in 2014 and $34 million in 2015.

Employee stock purchase plan

Options outstanding under the employee stock purchase plan at December 31, 2011, had an exercise price of $25.29 per share (85 percent of the fair market value of TI common stock on the date of automatic exercise). Of the total outstanding options, none were exercisable at year-end 2011.

Employee stock purchase plan transactions during 2011 were as follows:



	Employee Stock Purchase Plan (Shares)		Exercise Price
Outstanding grants, December 31, 2010	487,871		$	27.83
Granted	2,200,718		26.04
Exercised	(2,108,494	)	26.66
Outstanding grants, December 31, 2011	580,095		$	25.29

The weighted average grant-date fair value of options granted under the employee stock purchase plans during the years 2011, 2010 and 2009 was $4.59, $3.97 and $3.13 per share, respectively. During the years ended December 31, 2011, 2010 and 2009, the total intrinsic value of options exercised under these plans was $10 million, $9 million and $10 million, respectively.

Effect on shares outstanding and treasury shares

Our practice is to issue shares of common stock upon exercise of stock options generally from treasury shares and, on a limited basis, from previously unissued shares. We settled stock option plan exercises using treasury shares of 27,308,311 in 2011; 19,077,274 in 2010 and 6,695,583 in 2009; and previously unissued common shares of 390,438 in 2011; 342,380 in 2010 and 93,648 in 2009.

Upon vesting of RSUs, we issued treasury shares of 3,822,475 in 2011; 1,392,790 in 2010 and 977,728 in 2009, and previously unissued common shares of 73,852 in 2011,with none in 2010 and 2009.

Shares available for future grant and reserved for issuance are summarized below:



	As of December 31, 2011
Shares	Long-term Incentive and Director Compensation Plans		Employee Stock Purchase Plan		Total
Reserved for issuance (a)	224,383,737		27,967,317		252,351,054

Available for future grants	87,627,830		27,387,222		115,015,052

(a) Includes 123,667 shares credited to directors’ deferred compensation accounts that may settle in shares of TI common stock. These shares are not included as grants outstanding at December 31, 2011.

Effect on cash flows

Cash received from the exercise of options was $690 million in 2011, $407 million in 2010 and $109 million in 2009. The related net tax impact realized was $45 million, $21 million and ($2) million (which includes excess tax benefits realized of $31 million, $13 million and $1 million) in 2011, 2010 and 2009, respectively.

Profit sharing plans	12 Months Ended
Profit sharing plans	Dec. 31, 2011
Profit sharing plans [Abstract]
Profit sharing plans	Profit sharing plans Profit sharing benefits are generally formulaic and determined by one or more subsidiary or company-wide financial metrics. We pay profit sharing benefits primarily under the company-wide TI Employee Profit Sharing Plan. This plan provides for profit sharing to be paid based solely on TI’s operating margin for the full calendar year. Under this plan, TI must achieve a minimum threshold of 10 percent operating margin before any profit sharing is paid. At 10 percent operating margin, profit sharing will be 2 percent of eligible payroll. The maximum amount of profit sharing available under the plan is 20 percent of eligible payroll, which is paid only if TI’s operating margin is at or above 35 percent for a full calendar year. We recognized $143 million, $279 million and $102 million of profit sharing expense under the TI Employee Profit Sharing Plan in 2011, 2010 and 2009, respectively.

- Definition

Tabular disclosure of arrangements with individual employees that are not equity-based payments or pensions and other postretirement benefits, which are generally employment contracts between the entity and selected officers or key employees containing a promise by the employer to pay certain amounts at designated future dates, usually including a period after retirement, upon compliance with stipulated requirements. This type of arrangement is distinguished from broader based employee benefit plans as it is usually tailored to the employee. Examples may include profit sharing, deferred bonuses or certain split-dollar life insurance arrangements. Disclosure also typically includes the amount of related compensation expense recognized during the reporting period and the carrying amount as of the balance sheet date of the related liability.

As of December 31, 2011 and 2010, net deferred income tax assets of $888 million and $1.61 billion were presented in the balance sheets, based on tax jurisdiction, as deferred income tax assets of $1.50 billion and $1.70 billion and deferred income tax liabilities of $607 million and $86 million, respectively. The decrease in net deferred income tax assets from December 31, 2010, to December 31, 2011, is due to the recording of $881 million of net deferred tax liabilities associated with the acquisition of National, partially offset by the $119 million deferred tax provision.

We make an ongoing assessment regarding the realization of U.S. and non-U.S. deferred tax assets. In 2011, we recognized a net increase of $175 million in our valuation allowance. This increase was due to valuation allowances on unutilized tax credits associated with the acquisition of National. While the net deferred assets of $2.46 billion at December 31, 2011, are not assured of realization, our assessment is that a valuation allowance is not required on this balance. This assessment is based on our evaluation of relevant criteria including the existence of deferred tax liabilities that can be used to absorb deferred tax assets, taxable income in prior carryback years and expectations for future taxable income.

We have U.S. and non-U.S. tax loss carryforwards of approximately $202 million, of which $124 million expire through the year 2021.

Provision has been made for deferred taxes on undistributed earnings of non-U.S. subsidiaries to the extent that dividend

payments from these subsidiaries are expected to result in additional tax liability. The remaining undistributed earnings (approximately $4.12 billion at December 31, 2011) have been indefinitely reinvested; therefore, no provision has been made for taxes due upon remittance of these earnings. The indefinitely reinvested earnings of our non-U.S. subsidiaries are primarily invested in tangible assets such as inventory and property, plant and equipment. Determination of the amount of unrecognized deferred income tax liability is not practical because of the complexities associated with its hypothetical calculation.

Cash payments made for income taxes, net of refunds, were $902 million, $1.47 billion and $331 million for the years ended December 31, 2011, 2010 and 2009, respectively.

Uncertain tax positions

We operate in a number of tax jurisdictions, and our income tax returns are subject to examination by tax authorities in those jurisdictions who may challenge any item on these tax returns. Because the matters challenged by authorities are typically complex, their ultimate outcome is uncertain. Before any benefit can be recorded in the financial statements, we must determine that it is “more likely than not” that a tax position will be sustained by the appropriate tax authorities. We recognize accrued interest related to uncertain tax positions and penalties as components of OI&E.

The changes in the total amounts of uncertain tax positions are summarized as follows:



	2011			2010			2009
Balance, January 1	$	103		$	56		$	148
Additions based on tax positions related to the current year	15			12			10
Additions from the acquisition of National	132			—			—
Additions for tax positions of prior years	3			50			6
Reductions for tax positions of prior years	(39		)	(12		)	(18		)
Settlements with tax authorities	(4		)	(3		)	(90		)
Balance, December 31	$	210		$	103		$	56
Interest income (expense) recognized in the year ended December 31	$	1		$	(2	)	$	—
Accrued interest payable (receivable) as of December 31	$	3		$	(5	)	$	(9	)

The liability for uncertain tax positions and the accrued interest payable are components of Deferred credits and other liabilities on our December 31, 2011, balance sheet.

Within the $210 million liability for uncertain tax positions as of December 31, 2011, are uncertain tax positions totaling $233 million that, if recognized, would impact the tax rate. If these tax liabilities are ultimately realized, $83 million of deferred tax assets would also be realized, primarily related to refunds from counterparty jurisdictions resulting from procedures for relief from double taxation.

Within the $103 million liability for uncertain tax positions as of December 31, 2010, are uncertain tax positions totaling $136 million that, if recognized, would impact the tax rate. If these tax liabilities are ultimately realized, $101 million of deferred tax assets would also be realized, primarily related to refunds from counterparty jurisdictions resulting from procedures for relief from double taxation.

As of December 31, 2011, the statute of limitations remains open for U.S. federal tax returns for 1999 and following years. Audits of our U.S. federal tax returns through 2006 have been completed except for certain pending tax treaty procedures for relief from double taxation. These procedures pertain to U.S. federal tax returns for the years 2003 through 2007.

In non-U.S. jurisdictions, the years open to audit represent the years still subject to the statute of limitations. With respect to major jurisdictions outside the U.S., our subsidiaries are no longer subject to income tax audits for years before 2004.

We are unable to estimate the range of any reasonably possible increase or decrease in uncertain tax positions that may occur

within the next 12 months resulting from the eventual outcome of the years currently under audit or appeal. However, we do not anticipate any such outcome will result in a material change to our financial condition or results of operations. U.S. federal tax returns for recently acquired National are currently under audit for tax years through 2009. It is possible that issues that are the subject of that audit could be resolved in the next 12 months and result in a material change in our estimate of uncertain tax positions.

Financial instruments and risk concentration

Risks and Uncertainties [Abstract]

Financial instruments and risk concentration

Financial instruments

We hold derivative financial instruments such as forward foreign currency exchange contracts, interest rate swaps and forward purchase contracts, the fair value of which is not material at December 31, 2011. Our forward foreign currency exchange contracts outstanding at December 31, 2011, had a notional value of $516 million to hedge our non-U.S. dollar net balance sheet exposures (including $253 million to sell Japanese yen, $105 million to sell euros and $39 million to sell British pound sterling).

Our investments in cash equivalents, short-term investments and certain long-term investments, as well as our postretirement plan assets, contingent consideration and deferred compensation liabilities are carried at fair value, which is described in Note 9. The carrying values for other current financial assets and liabilities, such as accounts receivable and accounts payable, approximate fair value due to the short maturity of such instruments. The carrying value of our long-term debt approximates the fair value.

Risk concentration

Financial instruments that could subject us to concentrations of credit risk are primarily cash, cash equivalents, short-term investments and accounts receivable. In order to manage our credit risk exposure, we place cash investments in investment-grade debt securities and limit the amount of credit exposure to any one issuer. We also limit counterparties on forward foreign currency exchange contracts to financial institutions rated no lower than A3/A-.

Concentrations of credit risk with respect to accounts receivable are limited due to our large number of customers and their dispersion across different industries and geographic areas. We maintain an allowance for losses based on the expected collectability of accounts receivable. These allowances are deducted from accounts receivable on our Consolidated balance sheets.

Details of these allowances are as follows:



Accounts receivable allowances	Balance at Beginning of Year		Additions Charged (Credited) to Operating Results			Recoveries and Write-offs, Net			Balance at End of Year
2011	$	18	$	1		$	—		$	19
2010	23		(4		)	(1		)	18
2009	30		1			(8		)	23

- Definition

The entire disclosure for any concentrations existing at the date of the financial statements that make an entity vulnerable to a reasonably possible, near-term, severe impact. This disclosure informs financial statement users about the general nature of the risk associated with the concentration, and may indicate the percentage of concentration risk as of the balance sheet date.

Valuation of debt and equity investments and certain liabilities

12 Months Ended

Valuation of debt and equity investments and certain liabilities [Abstract]

Valuation of debt and equity investments and certain liabilities

Debt and equity investments

We classify our investments as available for sale, trading, equity method or cost method. Most of our investments are classified as available for sale.

Available-for-sale and trading securities are stated at fair value, which is generally based on market prices, broker quotes or, when necessary, financial models (see fair-value discussion below). Unrealized gains and losses on available-for-sale securities are recorded as an increase or decrease, net of taxes, in AOCI on our Consolidated balance sheets. We record other-than-temporary losses (impairments) on available-for-sale securities in OI&E in our Consolidated statements of income.

We classify certain mutual funds as trading securities. These mutual funds hold a variety of debt and equity investments intended to generate returns that offset changes in certain deferred compensation liabilities. We record changes in the fair value of these mutual funds and the related deferred compensation liabilities in SG&A. Changes in the fair value of debt securities classified as trading securities are recorded in OI&E.

Our other investments are not measured at fair value but are accounted for using either the equity method or cost method. These investments consist of interests in venture capital funds and other non-marketable equity securities. Gains and losses from equity method investments are reflected in OI&E based on our ownership share of the investee’s financial results. Gains and losses on cost method investments are recorded in OI&E when realized or when an impairment of the investment’s value is warranted based on our assessment of the recoverability of each investment.

Details of our investments and related unrealized gains and losses included in AOCI are as follows:



	December 31, 2011						December 31, 2010
	Cash and Cash Equivalents		Short-term Investments		Long-term Investments		Cash and Cash Equivalents		Short-term Investments		Long-term Investments

Unrealized losses (pre-tax)	$	—	$	—	$	5	$	—	$	1	$	22

As of December 31, 2011 and 2010, the majority of unrealized losses included in AOCI were associated with auction-rate securities classified as securities that are available for sale. We have determined that our available-for-sale investments with unrealized losses are not other-than-temporarily impaired as we expect to recover the entire cost basis of these securities. We do not intend to sell these investments, nor do we expect to be required to sell these investments, before a recovery of the cost basis. In the second quarter of 2011, we recategorized certain auction-rate securities from an available-for-sale classification to a trading classification, as we intend to sell them. For the year ended December 31, 2011, we did not recognize in earnings any credit losses related to these investments.

Proceeds from sales, redemptions and maturities of short-term available-for-sale securities, excluding cash equivalents, were $3.55 billion, $2.56 billion and $2.03 billion in 2011, 2010 and 2009, respectively. Gross realized gains and losses from these sales were not significant.

The following table presents the aggregate maturities of investments in debt securities classified as available for sale at

December 31, 2011:



Due	Fair Value
One year or less	$	1,902
One to three years	568
Greater than three years (auction-rate securities)	41

Gross realized gains and losses from sales of long-term investments were not significant for 2011, 2010 or 2009. Other-than-temporary declines and impairments in the values of these investments recognized in OI&E were $2 million, $1 million and $14 million in 2011, 2010 and 2009, respectively.

Fair-value considerations

We measure and report certain financial assets and liabilities at fair value on a recurring basis. Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date.

The three-level hierarchy discussed below indicates the extent and level of judgment used to estimate fair-value measurements.



Level 1 –	Uses unadjusted quoted prices that are available in active markets for identical assets or liabilities as of the reporting date.
Level 2 –	Uses inputs other than Level 1 that are either directly or indirectly observable as of the reporting date through correlation with market data, including quoted prices for similar assets and liabilities in active markets and quoted prices in markets that are not active. Level 2 also includes assets and liabilities that are valued using models or other pricing methodologies that do not require significant judgment since the input assumptions used in the models, such as interest rates and volatility factors, are corroborated by readily observable data. Our Level 2 assets consist of corporate obligations, some U.S. government agency securities and auction-rate securities that have been called for redemption. We utilize a third-party data service to provide Level 2 valuations, verifying these valuations for reasonableness relative to unadjusted quotes obtained from brokers or dealers based on observable prices for similar assets in active markets.
Level 3 –	Uses inputs that are unobservable, supported by little or no market activity and reflect the use of significant management judgment. These values are generally determined using pricing models that utilize management estimates of market participant assumptions.

Our auction-rate securities are primarily classified as Level 3 assets. Auction-rate securities are debt instruments with variable interest rates that historically would periodically reset through an auction process. These auctions have not functioned since 2008. There is no active secondary market for these securities, although limited observable transactions do occasionally occur. As a result, we use a discounted cash flow model to determine the estimated fair value of these investments as of each quarter end. The assumptions used in preparing the discounted cash flow model include estimates for the amount and timing of future interest and principal payments and the rate of return required by investors to own these securities in the current environment. In making these assumptions, we consider relevant factors including: the formula for each security that defines the interest rate paid to investors in the event of a failed auction; forward projections of the interest rate benchmarks specified in such formulas; the likely timing of principal repayments; the probability of full repayment considering the guarantees by the U.S. Department of Education of the underlying student loans and additional credit enhancements provided through other means; and, publicly available pricing data for student loan asset-backed securities that are not subject to auctions. Our estimate of the rate of return required by investors to own these securities also considers the reduced liquidity for auction-rate securities. To date, we have collected all interest on all of our auction-rate securities when due and expect to continue to do so in the future.

The following are our assets and liabilities that were accounted for at fair value on a recurring basis as of December 31, 2011 and 2010. These tables do not include cash on hand, assets held by our postretirement plans, or assets and liabilities that are measured at historical cost or any basis other than fair value.

The following table summarizes the change in the fair values for Level 3 assets and liabilities for the years ended December 31, 2011 and 2010. The transfer of auction-rate securities into Level 2 was the result of these securities being called for redemption and all were subsequently redeemed.

Acquisitions and divestitures other than National [Member]
Business Acquisitions and Divestitures [Line Items]
Acquisitions and divestitures	Acquisitions and divestitures other than National Acquisitions In October 2010, we acquired our first semiconductor manufacturing site in China, located in the Chengdu High-tech Zone. This included a fully equipped and operational 200-millimeter wafer fabrication facility (fab), as well as a non-operating fab that is being held for future capacity expansion. Additionally, we offered employment to the majority of existing employees at the Chengdu site. We provided transitional supply services through the middle of 2011, while also installing our analog production processes. This acquisition, which was recorded as a business combination, used net cash of $140 million. As contractually agreed, we made an additional payment to the seller in October 2011.We recorded $158 million of property, plant and equipment, $5 million of inventory, $4 million of other assets and $8 million of expenses. Operating results for the transitional supply services are included in Other. Additionally, we incurred acquisition costs of $2 million. In August 2010, we completed the acquisition of two wafer fabs and equipment in Aizu-Wakamatsu, Japan, for net cash of $130 million. The terms of the acquisition included an operational 200-millimeter fab as well as a non-operating fab capable of either 200- or 300-millimeter production that is being held for future capacity expansion. Additionally, we offered employment to the existing employees at the Aizu site. We provided transitional supply services through 2011, while also installing our analog production processes. The acquisition of the two Aizu wafer fabs and related 200-millimeter equipment was recorded as a business combination for net cash of $59 million. We recorded $42 million of property, plant and equipment, $9 million of inventory and $8 million of expenses, which were charged to COR. Operating results for the transitional supply services are included in Other. In connection with the Aizu acquisition, we also settled a contractual arrangement with a third party for our benefit for net cash of $12 million, which was recorded as a charge in COR in Other. Additionally, we incurred acquisition-related costs of $1 million, which were recorded in SG&A. The Aizu acquisition also included 300-millimeter production tools, which we recorded as a capital purchase for net cash of $58 million. In 2009, we acquired Luminary Micro for net cash of $51 million and other consideration of $7 million. These operations were integrated into our Embedded Processing segment. We also acquired CICLON Semiconductor Device Corporation for net cash of $104 million and other consideration of $7 million. These operations were integrated into our Analog segment. The results of operations for these acquisitions have been included in our financial statements from their respective acquisition dates. Pro forma financial information would not be materially different from amounts reported. Divestitures In November 2010, we divested a product line previously included in Other for $148 million and recognized a gain in operating profit of $144 million. This appears in the Consolidated statements of income on the Acquisition charges/divestiture (gain) line for 2010.

Goodwill and acquisition-related intangibles

The following table summarizes the changes in goodwill by segment for the years ended December 31, 2011 and 2010:



	Analog			Embedded Processing		Wireless		Other			Total
Goodwill, December 31, 2009	$	638		$	172	$	82	$	34		$	926

There was no impairment of goodwill during 2011 or 2010. In the first quarter of 2010, we transferred a low-power wireless product line, including the associated goodwill, from the Analog segment to the Wireless segment. We reduced goodwill in Other by $2 million, which was related to the divestiture noted in Note 10. The addition to Analog goodwill was from the National acquisition.

In 2011, we recognized intangible assets associated with the National acquisition of $2.96 billion, primarily for developed technology and customer relationships. In 2010, we had no additional intangible assets from an acquisition.

The following table shows the components of acquisition-related intangible assets as of December 31, 2011 and 2010:

Compensation and Retirement Disclosure [Abstract]

Postretirement benefit plans

Plan descriptions

We have various employee retirement plans including defined benefit, defined contribution and retiree health care benefit plans. For qualifying employees, we offer deferred compensation arrangements. As a part of the National acquisition, we assumed the assets and liabilities of its defined benefit plans, primarily those associated with the United Kingdom and Germany.

U.S. retirement plans:

Principal retirement plans in the U.S. are qualified and non-qualified defined benefit pension plans (all of which were closed to new participants after November 1997), a defined contribution plan and an enhanced defined contribution plan. The defined benefit pension plans include employees still accruing benefits as well as employees and participants who no longer accrue service-related benefits, but instead, may participate in the enhanced defined contribution plan.

Both defined contribution plans offer an employer-matching savings option that allows employees to make pre-tax contributions to various investment choices, including a TI common stock fund. Employees who elected to continue accruing a benefit in the qualified defined benefit pension plans may also participate in the defined contribution plan, where employer-matching contributions are provided for up to 2 percent of the employee’s annual eligible earnings. Employees who elected not to continue accruing a benefit in the defined benefit pension plans, and employees hired after November 1997 and through December 31, 2003, may participate in the enhanced defined contribution plan. This plan provides for a fixed employer contribution of 2 percent of the employee’s annual eligible earnings, plus an employer-matching contribution of up to 4 percent of the employee’s annual eligible earnings. Employees hired after December 31, 2003, do not receive the fixed employer contribution of 2 percent of the employee’s annual eligible earnings.

At December 31, 2011 and 2010, as a result of employees’ elections, TI’s U.S. defined contribution plans held shares of TI common stock totaling 22 million shares and 24 million shares valued at $639 million and $792 million, respectively. Dividends paid on these shares for 2011 and 2010 were $13 million for each year.

Our aggregate expense for the U.S. defined contribution plans was $55 million in 2011, $50 million in 2010 and $51 million in 2009.

Benefits under the qualified defined benefit pension plan are determined using a formula based upon years of service and the highest five consecutive years of compensation. We intend to contribute amounts to this plan to meet the minimum funding requirements of applicable local laws and regulations, plus such additional amounts as we deem appropriate. The non-qualified defined benefit plans are unfunded and closed to new participants.

U.S. retiree health care benefit plan:

U.S. employees who meet eligibility requirements are offered medical coverage during retirement. We make a contribution toward the cost of those retiree medical benefits for certain retirees and their dependents. The contribution rates are based upon various factors, the most important of which are an employee’s date of hire, date of retirement, years of service and eligibility for Medicare benefits. The balance of the cost is borne by the plan’s participants. Employees hired after January 1, 2001, are responsible for the full cost of their medical benefits during retirement.

Non-U.S. retirement plans:

We provide retirement coverage for non-U.S. employees, as required by local laws or to the extent we deem appropriate, through a number of defined benefit and defined contribution plans. Retirement benefits are generally based on an employee’s years of service and compensation. Funding requirements are determined on an individual country and plan basis and are subject to local country practices and market circumstances.

As of December 31, 2011 and 2010, as a result of employees’ elections, TI’s non-U.S. defined contribution plans held TI common stock valued at $12 million and $14 million, respectively. Dividends paid on these shares of TI common stock for 2011 and 2010 were not material.

Effect on the statements of income and balance sheets

Expense related to defined benefit and retiree health care benefit plans was as follows:



	U.S. Defined Benefit									U.S. Retiree Health Care									Non-U.S. Defined Benefit
	2011			2010			2009			2011			2010			2009			2011			2010			2009

(a) Includes restructuring and non-restructuring related settlement charges.

Expenses associated with National’s plans for the period from the acquisition date to December 31, 2011, were $2 million for non-U.S. defined benefit plans. National had no defined benefit plans in the U.S.

For the U.S. qualified pension and retiree health care plans, the expected return on the plan assets component of net periodic benefit cost is based upon a market-related value of assets. In accordance with U.S. GAAP, the market-related value of assets generally utilizes a smoothing technique whereby certain gains and losses are phased in over a period of three years.

Changes in the benefit obligations and plan assets for the defined benefit and retiree health care benefit plans were as follows:



	U.S. Defined Benefit						U.S. Retiree Health Care						Non-U.S. Defined Benefit

The investments in our major benefit plans largely consist of low-cost, broad-market index funds to mitigate risks of concentration within market sectors. In recent years, our investment policy has shifted toward a closer matching of the interest rate sensitivity of the plan assets and liabilities. The appropriate mix of equity and bond investments is determined primarily through the use of detailed asset-liability modeling studies that look to balance the impact of changes in the discount rate against the need to provide asset growth to cover future service cost. Most of our plans around the world have added a greater proportion of fixed income securities with return characteristics that are more closely aligned with changes in the liabilities caused by discount rate volatility. For the U.S. plans, we utilize an option collar strategy to reduce the volatility of returns on investments in U.S. equity funds.

The only Level 3 assets in our worldwide benefit plans are certain private equity limited partnerships in our U.S. pension plan and diversified hedge and property funds in a non-U.S. pension plan. These investments are valued using inputs from the fund managers and internal models.

The following table summarizes the change in the fair values for Level 3 plan assets for the years ending December 31, 2011 and 2010:

Assumptions and investment policies



	Defined Benefit		U.S. Retiree Health Care
	2011	2010	2011	2010
Weighted average assumptions used to determine benefit obligations:
U.S. discount rate	4.92%	5.58%	4.89%	5.48%
Non-U.S. discount rate	2.89%	2.79%

U.S. average long-term pay progression	3.50%	3.40%
Non-U.S. average long-term pay progression	3.18%	3.24%

Weighted average assumptions used to determine net periodic benefit cost:
U.S. discount rate	5.58%	5.61%	5.48%	5.54%
Non-U.S. discount rate	2.79%	3.23%

U.S. long-term rate of return on plan assets	6.25%	6.50%	5.50%	6.00%
Non-U.S. long-term rate of return on plan assets	4.17%	4.23%

U.S. average long-term pay progression	3.40%	3.00%
Non-U.S. average long-term pay progression	3.24%	3.06%

We utilize a variety of methods to select an appropriate discount rate depending on the depth of the corporate bond market in the country in which the benefit plan operates. In the U.S., we use a settlement approach whereby a portfolio of bonds is selected from the universe of actively traded high-quality U.S. corporate bonds. The selected portfolio is designed to provide cash flows sufficient to pay the plan’s expected benefit payments when due. The resulting discount rate reflects the rate of return of the selected portfolio of bonds. For our non-U.S. locations with a sufficient number of actively traded high-quality bonds, an analysis is performed in which the projected cash flows from the defined benefit plans are discounted against a yield curve constructed with an appropriate universe of high-quality corporate bonds available in each country. In this manner, a present value is developed. The discount rate selected is the single equivalent rate that produces the same present value. Both the settlement approach and the yield curve approach produce a discount rate that recognizes each plan’s distinct liability characteristics. For countries that lack a sufficient corporate bond market, a government bond index adjusted for an appropriate risk premium is used to establish the discount rate.

Assumptions for the expected long-term rate of return on plan assets are based on future expectations for returns for each asset class and the effect of periodic target asset allocation rebalancing. We adjust the results for the payment of reasonable expenses of the plan from plan assets. We believe our assumptions are appropriate based on the investment mix and long-term nature of the plans’ investments.

Assumptions used for the non-U.S. defined benefit plans reflect the different economic environments within the various countries.

The table below shows target allocation ranges for the plans that hold a substantial majority of the defined benefit assets.



Asset category	U.S. Defined Benefit	U.S. Retiree Health Care	Non-U.S. Defined Benefit
Equity securities	35%	50%	25% - 60%
Fixed income securities and cash equivalents	65%	50%	40% - 75%

We intend to rebalance the plans’ investments when they are not within the target allocation ranges. Additional contributions are invested consistent with the target ranges and may be used to rebalance the portfolio. The investment allocations and individual investments are chosen with regard to the duration of the obligations of each plan. Most of the assets in the retiree health care benefit plan are invested in a series of Voluntary Employee Benefit Association (VEBA) trusts.

Weighted average asset allocations at December 31, are as follows:



	U.S. Defined Benefit		U.S. Retiree Health Care		Non-U.S. Defined Benefit
Asset category	2011	2010	2011	2010	2011	2010
Equity securities	35%	35%	48%	49%	32%	49%
Fixed income securities	63%	60%	41%	41%	66%	50%
Cash equivalents	2%	5%	11%	10%	2%	1%

None of the plan assets related to the defined benefit pension plans and retiree health care benefit plan are directly invested in TI common stock. As of December 31, 2011, we do not expect to return any of the plans’ assets to TI in the next 12 months.

Contributions to the plans meet or exceed all minimum funding requirements. We expect to contribute about $120 million to our retirement benefit plans in 2012.

The following table shows the benefits we expect to pay to participants from the plans in the next ten years. Almost all of the payments will be made from plan assets and not from company assets.



	U.S. Defined Benefit		U.S. Retiree Health Care		Medicare Subsidy			Non-U.S. Defined Benefit
2012	$	160	$	35	$	(4	)	$	77
2013	92		37		(4		)	80
2014	91		39		(4		)	82
2015	94		41		(2		)	89
2016	95		43		(2		)	92
2017–2021	451		213		(10		)	525

Assumed health care cost trend rates for the U.S. retiree health care plan at December 31 are as follows:



	2011	2010
Assumed health care cost trend rate for next year	9.0%	9.0%
Ultimate trend rate	5.0%	5.0%
Year in which ultimate trend rate is reached	2017	2016

Increasing or decreasing health care cost trend rates by one percentage point would have increased or decreased the accumulated postretirement benefit obligation for the U.S. retiree health care plan at December 31, 2011, by $28 million or $24 million and increased or decreased the service cost and interest cost components of 2011 plan expense by $1 million.

Deferred compensation arrangements

We have a deferred compensation plan, which allows U.S. employees whose base salary and management responsibility exceed a certain level to defer receipt of a portion of their cash compensation. Payments under this plan are made based on the participant’s distribution election and plan balance. Participants can earn a return on their deferred compensation based on notional investments in the same investment funds that are offered in our defined contribution plans.

As of December 31, 2011, our liability to participants of the deferred compensation plan was $150 million and is recorded in Deferred credits and other liabilities on our Consolidated balance sheets. This amount reflects the accumulated participant deferrals and earnings thereon as of that date. No assets are held in trust for the deferred compensation plan and so we remain liable to the participants. To serve as an economic hedge against changes in fair values of this liability, we invest in similar mutual funds that are recorded in Long-term investments. We record changes in the fair value of the liability and the related investment in SG&A (see Note 9).

In connection with the National acquisition, we assumed its deferred compensation plan. As of December 31, 2011, this consisted of $41 million of obligations and matching assets held in a Rabbi trust. No further contributions will be made into this plan.

Debt and lines of credit

12 Months Ended

Dec. 31, 2011

Long-term Debt, Unclassified [Abstract]

Debt and lines of credit

Debt balances include amounts assumed related to the National acquisition measured at fair value as of the acquisition date.

Short-term borrowings

We maintain lines of credit to support commercial paper borrowings, if any, and to provide additional liquidity through bank loans. As of December 31, 2011, we had a variable-rate revolving credit facility that allows us to borrow up to $920 million through August 2012. We have a second variable-rate revolving credit facility that allows us to borrow an additional $1 billion until July 2012. These facilities carry a variable rate of interest indexed to the London Interbank Offered Rate (LIBOR).

On July 14, 2011, for general corporate purposes and to maintain cash balances at desired levels, we issued an aggregate of $1.2 billion of commercial paper, which was supported by these existing revolving credit facilities. During the fourth quarter, we repaid $200 million of those borrowings. As of December 31, 2011, the balance of commercial paper outstanding was $1.0 billion. The weighted-borrowing rate for the commercial paper outstanding as of December 31, 2011, was 0.25 percent.

Long-term debt

On May 23, 2011, we issued fixed- and floating-rate long-term debt to help fund the National acquisition. The proceeds of the offering were $3.497 billion, net of the original issuance discount. We also incurred $12 million of issuance costs that are included in Other assets and will be amortized to Interest and debt expense over the term of the debt.

In connection with this issuance, we also entered into an interest rate swap transaction related to the $1.0 billion floating-rate debt due 2013. Under this swap agreement, we will receive variable payments based on three-month LIBOR rates and pay a fixed rate through May 15, 2013. Changes in the cash flows of the interest rate swap are expected to exactly offset the changes in cash flows attributable to fluctuations in the three-month LIBOR-based interest payments. We have designated this interest rate swap as a cash flow hedge and record changes in its fair value in AOCI. The net effect of this swap is to convert the $1.0 billion floating-rate debt to a fixed-rate obligation bearing a rate of 0.922 percent.

At the acquisition date, we assumed $1.0 billion of outstanding National debt with a fair value of $1.105 billion. The excess of the fair value over the stated value will be amortized as a reduction of interest and debt expense over the term of the related debt.

The following table summarizes the total long-term debt outstanding as of December 31, 2011:



Notes due 2012 at 6.15% (assumed with National acquisition)	$	375
Floating-rate notes due 2013 (swapped to a 0.922% fixed rate)	1,000
Notes due 2013 at 0.875%	500
Notes due 2014 at 1.375%	1,000
Notes due 2015 at 3.95% (assumed with National acquisition)	250
Notes due 2016 at 2.375%	1,000
Notes due 2017 at 6.60% (assumed with National acquisition)	375
	4,500
Add net unamortized premium (assumed with National acquisition)	93
Less current portion of long-term debt	(382		)
Total long-term debt	$	4,211

As of December 31, 2010, we had no outstanding debt. Interest incurred on debt and amortization of debt expense was $42 million in 2011. Interest incurred in 2010 and 2009 was not material. Cash payments for interest on long-term debt were $54 million in 2011.

Commitments and contingencies

12 Months Ended

Dec. 31, 2011

Commitments and Contingencies Disclosure [Abstract]

Commitments and contingencies

Operating leases

We conduct certain operations in leased facilities and also lease a portion of our data processing and other equipment. In addition, certain long-term supply agreements to purchase industrial gases are accounted for as operating leases. Lease agreements frequently include purchase and renewal provisions and require us to pay taxes, insurance and maintenance costs. Rental and lease expense incurred was $109 million, $100 million and $114 million in 2011, 2010 and 2009, respectively.

Capitalized software licenses

We have licenses for certain internal-use electronic design automation software that we account for as capital leases. The related liabilities are apportioned between Accounts payable and Deferred credits and other liabilities on our Consolidated balance sheets, depending on the contractual timing of the payment.

Purchase commitments

Some of our purchase commitments entered in the ordinary course of business provide for minimum payments. At December 31, 2011, we had committed to make the following minimum payments under our non-cancellable operating leases, capitalized software licenses and purchase commitments:



	Operating Leases		Capitalized Software Licenses		Purchase Commitments
2012	$	102	$	73	$	215
2013	77		35		97
2014	55		31		20
2015	48		12		4
2016	36		—		2
Thereafter	118		—		10

Indemnification guarantees

We routinely sell products with an intellectual property indemnification included in the terms of sale. Historically, we have had only minimal, infrequent losses associated with these indemnities. Consequently, we cannot reasonably estimate or accrue for any future liabilities that may result.

Warranty costs/product liabilities

We accrue for known product-related claims if a loss is probable and can be reasonably estimated. During the periods presented, there have been no material accruals or payments regarding product warranty or product liability. Historically, we have experienced a low rate of payments on product claims. Although we cannot predict the likelihood or amount of any future claims, we do not believe they will have a material adverse effect on our financial condition, results of operations or liquidity. Consistent with general industry practice, we enter into formal contracts with certain customers that include negotiated warranty remedies. Typically, under these agreements our warranty for semiconductor products includes: three years coverage; an obligation to repair, replace or refund; and a maximum payment obligation tied to the price paid for our products. In some cases, product claims may exceed the price of our products.

General

We are subject to various legal and administrative proceedings. Although it is not possible to predict the outcome of these matters, we believe that the results of these proceedings will not have a material adverse effect on our financial condition, results of operations or liquidity. From time to time, we also negotiate contingent consideration payment arrangements associated with certain acquisitions, which are recorded at fair value.

Discontinued operations indemnity

In connection with the 2006 sale of the former Sensors & Controls (S&C) business, we have agreed to indemnify Sensata Technologies, Inc., for specified litigation matters and certain liabilities, including environmental liabilities. In a settlement with a third party, we have agreed to indemnify that party for certain events relating to S&C products, which events we consider remote. We believe our total remaining potential exposure from both of these indemnities will not exceed $200 million. As of December 31, 2011, we believe future payments related to these indemnity obligations will not have a material effect on our financial condition, results of operations or liquidity.

Segment and geographic area data

Dec. 31, 2011

Segment Reporting [Abstract]

Segment and geograhic area data

Segment and geographic area data

Reportable segments

Our financial reporting structure comprises three reportable segments. These reportable segments, which are established along major categories of products having unique design and development requirements, are as follows:

Analog – Analog semiconductors change real-world signals – such as sound, temperature, pressure or images – by conditioning them, amplifying them and often converting them to a stream of digital data that can be processed by other semiconductors, such as digital signal processors (DSPs). Analog semiconductors are also used to manage power distribution and consumption. Analog includes the following major product lines: HVAL, Power, HPA and SVA.

Embedded Processing – Our Embedded Processing products include our DSPs and microcontrollers. DSPs perform mathematical computations almost instantaneously to process or improve digital data. Microcontrollers are designed to control a set of specific tasks for electronic equipment. We make and sell catalog Embedded Processing products used in many different applications and custom Embedded Processing products used in specific applications, such as communications infrastructure equipment and automotive.

Wireless – Growth in the wireless market is being driven by the demand for smartphones, tablet computers and other emerging portable devices. Many of today’s smartphones and tablets use an applications processor to run the device’s software operating system and enable expanded functionality. Many wireless devices also use other semiconductors to enable wireless connectivity using technologies such as Bluetooth®, WiFi networks, GPS, and Near Field Communications. Our OMAP applications processors and connectivity products enable us to take advantage of the increasing demand for more powerful and more functional mobile devices. We design, make and sell products to satisfy each of these requirements.Wireless products are typically sold in high volumes. Our Wireless portfolio includes both catalog products and custom products. Wireless also includes baseband products, which allow a cell phone to connect to the cellular network. We are no longer investing in the development of baseband products, and almost all of our current baseband products are sold to a single customer.

Other

In addition to our reportable segments, we also have Other. Other includes other operating segments that neither meet the quantitative thresholds for individually reportable segments nor are they aggregated with other operating segments. These operating segments primarily include our smaller semiconductor product lines such as DLP® products (primarily used in projectors to create high-definition images), custom semiconductors known as ASICs, and our handheld graphing and scientific calculators.

Other also includes royalties received for our patented technology that we license to other electronics companies and revenue from transitional supply agreements that we may enter into in connection with acquisitions and divestitures. Other may also include certain unallocated income and expenses such as gains and losses on sales of assets; sales tax refunds; and certain litigation costs, settlements or reserves. Except for these few unallocated items, we allocate all of our expenses associated with corporate activities to our operating segments based on specific methodologies, such as percentage of operating expenses or headcount.

Acquisition charges related to National are also recorded in Other in 2011, as detailed in Note 2. The expenses associated with the recognition of fair-value write-up of both inventory and property, plant and equipment are recorded in Other as well. Inventory-related expense was classified in COR as the inventory was sold. The property, plant and equipment-related expense is primarily recognized in COR.

Losses associated with the earthquake in Japan and Restructuring charges related to the 2011 announced actions in Hiji, Japan, and Houston, Texas, are also included in Other. See Notes 3 and 4 for additional information.

With the exception of goodwill, we do not identify or allocate assets by operating segment, nor does the chief operating decision maker evaluate operating segments using discrete asset information. There was no significant intersegment revenue. The accounting policies of the segments are the same as those described in the summary of significant accounting policies.

Description of business and significant accounting policies and practices [Abstract]
Basis of presentation	Basis of presentation The consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States (U.S. GAAP). The basis of these financial statements is comparable for all periods presented herein. The consolidated financial statements include the accounts of all subsidiaries. All intercompany balances and transactions have been eliminated in consolidation. All dollar amounts in the financial statements and tables in these notes, except per-share amounts, are stated in millions of U.S. dollars unless otherwise indicated. We have reclassified certain amounts in the prior periods’ financial statements to conform to the 2011 presentation. The preparation of financial statements requires the use of estimates from which final results may vary.
Revenue recognition	Revenue recognition We recognize revenue from direct sales of our products to our customers, including shipping fees, when title passes to the customer, which usually occurs upon shipment or delivery, depending upon the terms of the sales order; when persuasive evidence of an arrangement exists; when sales amounts are fixed or determinable; and when collectability is reasonably assured. Revenue from sales of our products that are subject to inventory consignment agreements is recognized when the customer pulls product from consignment inventory that we store at designated locations. Estimates of product returns for quality reasons and of price allowances (based on historical experience, product shipment analysis and customer contractual arrangements) are recorded when revenue is recognized. Allowances include volume-based incentives and special pricing arrangements. In addition, we record allowances for accounts receivable that we estimate may not be collected. We recognize revenue from direct sales of our products to our distributors, net of allowances, consistent with the principles discussed above. Title transfers to the distributors at delivery or when the products are pulled from consignment inventory, and payment is due on our standard commercial terms; payment terms are not contingent upon resale of the products. We also grant discounts to some distributors for prompt payments. We calculate credit allowances based on historical data, current economic conditions and contractual terms. For instance, we sell to distributors at standard published prices, but we may grant them price adjustment credits in response to individual competitive opportunities they may have. To estimate allowances, we use statistical percentages of revenue, determined quarterly, based upon recent historical adjustment trends. We also provide distributors an allowance to scrap certain slow-moving or obsolete products in their inventory, estimated as a negotiated fixed percentage of each distributor’s purchases from us. In addition, if we publish a new price for a product that is lower than that paid by distributors for the same product still remaining in each distributor’s on-hand inventory, we may credit them for the difference between those prices. The allowance for this type of credit is based on the identified product price difference applied to our estimate of each distributor’s on-hand inventory of that product. We believe we can reasonably and reliably estimate allowances for credits to distributors in a timely manner. We determine the amount and timing of royalty revenue based on our contractual agreements with intellectual property licensees. We recognize royalty revenue when earned under the terms of the agreements and when we consider realization of payment to be probable. Where royalties are based on a percentage of licensee sales of royalty-bearing products, we recognize royalty revenue by applying this percentage to our estimate of applicable licensee sales. We base this estimate on historical experience and an analysis of each licensee’s sales results. Where royalties are based on fixed payment amounts, we recognize royalty revenue ratably over the term of the royalty agreement. Where warranted, revenue from licensees may be recognized on a cash basis. We include shipping and handling costs in COR.
Advertising costs	Advertising costs We expense advertising and other promotional costs as incurred.
Income taxes	Income taxes We account for income taxes using an asset and liability approach. We record the amount of taxes payable or refundable for the current year and the deferred tax assets and liabilities for future tax consequences of events that have been recognized in the financial statements or tax returns. We record a valuation allowance when it is more likely than not that some portion or all of the deferred tax assets will not be realized.
Other assessed taxes	Other assessed taxes Some transactions require us to collect taxes such as sales, value-added and excise taxes from our customers. These transactions are presented in our statements of income on a net (excluded from revenue) basis.
Earnings per share	Earnings per share (EPS) Unvested awards of share-based payments with rights to receive dividends or dividend equivalents, such as our restricted stock units (RSUs), are considered to be participating securities and the two-class method is used for purposes of calculating EPS. Under the two-class method, a portion of net income is allocated to these participating securities and, therefore, is excluded from the calculation of EPS allocated to common stock, as shown in the table below.
Investments	Investments We present investments on our balance sheets as cash equivalents, short-term investments or long-term investments. Specific details are as follows: Cash equivalents and short-term investments: We consider investments in debt securities with maturities of three months or less from the date of our investment to be cash equivalents. We consider investments in debt securities with maturities beyond three months from the date of our investment as being available for use in current operations and include these investments in short-term investments. The primary objectives of our cash equivalent and short-term investment activities are to preserve capital and maintain liquidity while generating appropriate returns. Long-term investments: Long-term investments consist of mutual funds, auction-rate securities, venture capital funds and non-marketable equity securities. Classification of investments: Depending on our reasons for holding the investment and our ownership percentage, we classify investments in securities as available for sale, trading, equity-method or cost-method investments, which are more fully described in Note 9. We determine cost or amortized cost, as appropriate, on a specific identification basis. We classify our investments as available for sale, trading, equity method or cost method. Most of our investments are classified as available for sale. Available-for-sale and trading securities are stated at fair value, which is generally based on market prices, broker quotes or, when necessary, financial models (see fair-value discussion below). Unrealized gains and losses on available-for-sale securities are recorded as an increase or decrease, net of taxes, in AOCI on our Consolidated balance sheets. We record other-than-temporary losses (impairments) on available-for-sale securities in OI&E in our Consolidated statements of income. We classify certain mutual funds as trading securities. These mutual funds hold a variety of debt and equity investments intended to generate returns that offset changes in certain deferred compensation liabilities. We record changes in the fair value of these mutual funds and the related deferred compensation liabilities in SG&A. Changes in the fair value of debt securities classified as trading securities are recorded in OI&E. Our other investments are not measured at fair value but are accounted for using either the equity method or cost method. These investments consist of interests in venture capital funds and other non-marketable equity securities. Gains and losses from equity method investments are reflected in OI&E based on our ownership share of the investee’s financial results. Gains and losses on cost method investments are recorded in OI&E when realized or when an impairment of the investment’s value is warranted based on our assessment of the recoverability of each investment.
Inventories	Inventories Inventories are stated at the lower of cost or estimated net realizable value. Cost is generally computed on a currently adjusted standard cost basis, which approximates cost on a first-in first-out basis. Standard cost is based on the normal utilization of installed factory capacity. Cost associated with underutilization of capacity is expensed as incurred. Inventory held at consignment locations is included in our finished goods inventory. Consigned inventory was $129 million and $130 million as of December 31, 2011 and 2010, respectively. We review inventory quarterly for salability and obsolescence. A specific allowance is provided for inventory considered unlikely to be sold. Remaining inventory includes a salability and obsolescence allowance based on an analysis of historical disposal activity. We write off inventory in the period in which disposal occurs.
Property, plant and equipment; acquisition-related intangibles and other capitalized costs	Property, plant and equipment; acquisition-related intangibles and other capitalized costs Property, plant and equipment are stated at cost and depreciated over their estimated useful lives using the straight-line method. Our cost basis includes certain assets acquired in business combinations that were initially recorded at fair value as of the date of acquisition. Leasehold improvements are amortized using the straight-line method over the shorter of the remaining lease term or the estimated useful lives of the improvements. We amortize acquisition-related intangibles on a straight-line basis over the estimated economic life of the assets. Capitalized software licenses generally are amortized on a straight-line basis over the term of the license. Fully depreciated or amortized assets are written off against accumulated depreciation or amortization.
Impairments of long-lived assets	Impairments of long-lived assets We regularly review whether facts or circumstances exist that indicate the carrying values of property, plant and equipment or other long-lived assets, including intangible assets, are impaired. We assess the recoverability of assets by comparing the projected undiscounted net cash flows associated with those assets to their respective carrying amounts. Any impairment charge is based on the excess of the carrying amount over the fair value of those assets. Fair value is determined by available market valuations, if applicable, or by discounted cash flows.
Goodwill and indefinite-lived intangibles	Goodwill and indefinite-lived intangibles Goodwill is not amortized but is reviewed for impairment annually or more frequently if certain impairment indicators arise. We complete our annual goodwill impairment tests as of October 1 for our reporting units. The test compares the fair value for each reporting unit to its associated carrying value including goodwill. We have had no impairment of goodwill for 2011 or 2010.
Foreign currency	Foreign currency The functional currency for our non-U.S. subsidiaries is the U.S. dollar. Accounts recorded in currencies other than the U.S. dollar are remeasured into the functional currency. Current assets (except inventories), deferred income taxes, other assets, current liabilities and long-term liabilities are remeasured at exchange rates in effect at the end of each reporting period. Property, plant and equipment with associated depreciation and inventories are remeasured at historic exchange rates. Revenue and expense accounts other than depreciation for each month are remeasured at the appropriate daily rate of exchange. Currency exchange gains and losses from remeasurement are credited or charged to OI&E.
Derivatives and hedging	Derivatives and hedging In connection with the issuance of variable-rate long-term debt in May 2011, as more fully described in Note 13, we entered into an interest rate swap designated as a hedge of the variability of cash flows related to interest payments. Gains and losses from changes in the fair value of the interest rate swap are credited or charged to Accumulated other comprehensive income (loss), net of taxes (AOCI). We also use derivative financial instruments to manage exposure to foreign exchange risk. These instruments are primarily forward foreign currency exchange contracts that are used as economic hedges to reduce the earnings impact exchange rate fluctuations may have on our non-U.S. dollar net balance sheet exposures or for specified non-U.S. dollar forecasted transactions. Gains and losses from changes in the fair value of these forward foreign currency exchange contracts are credited or charged to OI&E. We do not apply hedge accounting to our foreign currency derivative instruments. We do not use derivatives for speculative or trading purposes.

Restructuring charges (Policies)	Dec. 31, 2011
Restructuring and Related Activities [Abstract]
Restructuring policy	Restructuring charges may consist of voluntary or involuntary severance-related charges, asset-related charges and other costs to exit activities. We recognize voluntary termination benefits when the employee accepts the offered benefit arrangement. We recognize involuntary severance-related charges depending on whether the termination benefits are provided under an ongoing benefit arrangement or under a one-time benefit arrangement. If the former, we recognize the charges once they are probable and the amounts are estimable. If the latter, we recognize the charges once the benefits have been communicated to employees. Restructuring activities associated with assets would be recorded as an adjustment to the basis of the asset, not as a liability. When we commit to a plan to abandon a long-lived asset before the end of its previously estimated useful life, we accelerate the recognition of depreciation to reflect the use of the asset over its shortened useful life. When an asset is held to be sold, we write down the carrying value to its net realizable value and cease depreciation.

Stock-based compensation (Policies)	12 Months Ended
Stock-based compensation (Policies)	Dec. 31, 2011
Share-based Compensation [Abstract]
Share-based compensation policy	We determine expected volatility on all options granted after July 1, 2005, using available implied volatility rates. We believe that market-based measures of implied volatility are currently the best available indicators of the expected volatility used in these estimates. We determine expected lives of options based on the historical option exercise experience of our optionees using a rolling ten-year average. We believe the historical experience method is the best estimate of future exercise patterns currently available. Risk-free interest rates are determined using the implied yield currently available for zero-coupon U.S. government issues with a remaining term equal to the expected life of the options. Expected dividend yields are based on the approved annual dividend rate in effect and the current market price of our common stock at the time of grant. No assumption for a future dividend rate change is included unless there is an approved plan to change the dividend in the near term. The fair value per share of RSUs that we grant is determined based on the closing price of our common stock on the date of grant. Our employee stock purchase plan is a discount-purchase plan and consequently the Black-Scholes option-pricing model is not used to determine the fair value per share of these awards. The fair value per share under this plan equals the amount of the discount. We issue awards of non-qualified stock options generally with graded vesting provisions (e.g., 25 percent per year for four years). We recognize the related compensation cost on a straight-line basis over the minimum service period required for vesting of the award. For awards to employees who are retirement eligible or nearing retirement eligibility, we recognize compensation cost on a straight-line basis over the longer of the service period required to be performed by the employee in order to earn the award, or a six-month period. Our RSUs generally vest four years after the date of grant. We recognize the related compensation costs on a straight-line basis over the vesting period.

Valuation of debt and equity investments and certain liabilities [Abstract]

Investment policy

Investments

We present investments on our balance sheets as cash equivalents, short-term investments or long-term investments. Specific details are as follows:

Long-term investments: Long-term investments consist of mutual funds, auction-rate securities, venture capital funds and non-marketable equity securities.

We classify our investments as available for sale, trading, equity method or cost method. Most of our investments are classified as available for sale.

Fair value

Fair-value considerations

The three-level hierarchy discussed below indicates the extent and level of judgment used to estimate fair-value measurements.



Level 1 –	Uses unadjusted quoted prices that are available in active markets for identical assets or liabilities as of the reporting date.
Level 2 –	Uses inputs other than Level 1 that are either directly or indirectly observable as of the reporting date through correlation with market data, including quoted prices for similar assets and liabilities in active markets and quoted prices in markets that are not active. Level 2 also includes assets and liabilities that are valued using models or other pricing methodologies that do not require significant judgment since the input assumptions used in the models, such as interest rates and volatility factors, are corroborated by readily observable data. Our Level 2 assets consist of corporate obligations, some U.S. government agency securities and auction-rate securities that have been called for redemption. We utilize a third-party data service to provide Level 2 valuations, verifying these valuations for reasonableness relative to unadjusted quotes obtained from brokers or dealers based on observable prices for similar assets in active markets.
Level 3 –	Uses inputs that are unobservable, supported by little or no market activity and reflect the use of significant management judgment. These values are generally determined using pricing models that utilize management estimates of market participant assumptions.

- Definition

Disclosure of accounting policy for investments in financial assets, including marketable securities (debt and equity securities with readily determinable fair values), investments accounted for under the equity method and cost method, securities borrowed and loaned, and repurchase and resale agreements. For marketable securities, the disclosure may include the entity's accounting treatment for transfers between investment categories and how the fair values for such securities are determined. Also, for all investments, an entity may describe its policy for assessing, recognizing and measuring impairment of the investment.

Commitments and contingencies (Policies)	Dec. 31, 2011
Commitments and Contingencies Disclosure [Abstract]
Warranty costs and product liabilities policy	Indemnification guarantees We routinely sell products with an intellectual property indemnification included in the terms of sale. Historically, we have had only minimal, infrequent losses associated with these indemnities. Consequently, we cannot reasonably estimate or accrue for any future liabilities that may result. Warranty costs/product liabilities We accrue for known product-related claims if a loss is probable and can be reasonably estimated. During the periods presented, there have been no material accruals or payments regarding product warranty or product liability. Historically, we have experienced a low rate of payments on product claims. Although we cannot predict the likelihood or amount of any future claims, we do not believe they will have a material adverse effect on our financial condition, results of operations or liquidity. Consistent with general industry practice, we enter into formal contracts with certain customers that include negotiated warranty remedies. Typically, under these agreements our warranty for semiconductor products includes: three years coverage; an obligation to repair, replace or refund; and a maximum payment obligation tied to the price paid for our products. In some cases, product claims may exceed the price of our products. General We are subject to various legal and administrative proceedings. Although it is not possible to predict the outcome of these matters, we believe that the results of these proceedings will not have a material adverse effect on our financial condition, results of operations or liquidity. From time to time, we also negotiate contingent consideration payment arrangements associated with certain acquisitions, which are recorded at fair value.

- Definition

Tabular disclosure of components of a stock option or other award plan under which equity-based compensation is awarded to employees, typically comprised of the amount of unearned compensation (deferred compensation cost), compensation expense, and changes in the quantity and fair value of the shares (or other type of equity) granted, exercised, forfeited, and issued and outstanding pertaining to that plan. Disclosure may also include nature and general terms of such arrangements that existed during the period and potential effects of those arrangements on shareholders, effect of compensation cost arising from equity-based payment arrangements on the income statement, method of estimating the fair value of the goods or services received, or the fair value of the equity instruments granted, during the period, cash flow effects resulting from equity-based payment arrangements and, for registrants that accelerate vesting of out of the money share options, reasons for the decision to accelerate.
