Basis of Presentation	'
	Note 1 – Basis of Presentation
	Management prepared these unaudited interim consolidated financial statements for Zebra Technologies Corporation and subsidiaries (“Zebra”) according to the rules and regulations of the Securities and Exchange Commission (“SEC”) for interim financial information. These financial statements do not include all of the information and footnotes required by United States generally accepted accounting principles (“GAAP”) for complete financial statements. Therefore, these consolidated financial statements should be read in conjunction with the consolidated financial statements and notes included in Zebra’s Annual Report on Form 10-K for the fiscal year ended December 31, 2013.
	The consolidated balance sheet as of December 31, 2013, included in this Form 10-Q is taken from the audited consolidated balance sheet in our Form 10-K. These interim financial statements include all adjustments (of a normal, recurring nature) necessary to present fairly Zebra’s consolidated financial position as of September 27, 2014, the consolidated statements of earnings and consolidated statements of comprehensive income for the three and nine months ended September 27, 2014 and September 28, 2013 and the consolidated statements of cash flows for the nine months ended September 27, 2014 and September 28, 2013. These results, however, are not necessarily indicative of results for the full year.
	On April 14, 2014, Zebra entered into a definitive agreement under which Zebra will acquire a portion of the Enterprise business of Motorola Solutions, Inc. for $3.45 billion in an all-cash transaction. Zebra completed the transaction on October 27, 2014. See Note 18 for more details. Zebra funded the acquisition with a combination of approximately $200 million of available cash on hand and the issuance of $3.25 billion in new debt.

Fair Value Disclosures [Abstract]	'
Fair Value Measurements	'
	Note 2 – Fair Value Measurements
	Financial assets and liabilities are to be measured using inputs from three levels of the fair value hierarchy. Fair value is based on the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. Zebra uses a fair value hierarchy that prioritizes observable and unobservable inputs used to measure fair value into three broad levels:
	Level 1: Quoted prices (unadjusted) in active markets that are accessible at the measurement date for assets or liabilities. The fair value hierarchy gives the highest priority to Level 1 inputs.
	Level 2: Observable prices that are based on inputs not quoted on active markets, but corroborated by market data.
	Level 3: Unobservable inputs are used when little or no market data is available. The fair value hierarchy gives the lowest priority to Level 3 inputs.
	In determining fair value, we utilize valuation techniques that maximize the use of observable inputs and minimize the use of unobservable inputs to the extent possible as well as consider counterparty credit risk in the assessment of fair value. Included in our investment portfolio at September 27, 2014, is an auction rate security which is classified as available for sale and is reflected at fair value. Due to events in credit markets, however, the auction event for the instrument held by Zebra is failed. Therefore, the fair value of this security is estimated utilizing broker quotations, discounted cash flow analysis and other types of valuation adjustment methodologies at September 27, 2014. These analyses consider, among other items, the collateral underlying the security instruments, the creditworthiness of the counterparty, the timing of expected future cash flows, estimates of the next time the security is expected to have a successful auction, and Zebra’s intent and ability to hold such securities until credit markets improve. The security was also compared, when possible, to other securities with similar characteristics.
	On October 1, 2011, Zebra deemed the auction rate security discussed above to be temporarily impaired and recorded the estimated value decline of $412,000 in other comprehensive income. As of September 27, 2014 Zebra decided to dispose of the security during the fourth quarter of 2014 and has deemed the investment to be permanently impaired and recorded a loss of $600,000.

	1)	Includes investments in notes issued by the Federal Home Loan Mortgage Corporation, the Federal National Mortgage Association, the Federal Farm Credit Banks and the Federal Home Loan Bank.
	2)	The fair value of forward contracts are calculated as follows:
		a.	Fair value of a collar or put option contract associated with forecasted sales hedges are calculated using bid and ask rates for similar contracts.
		b.	Fair value of regular forward contracts associated with forecasted sales hedges are calculated using the period-end exchange rate adjusted for current forward points.
		c.	Fair value of balance sheet hedges are calculated at the period end exchange rate adjusted for current forward points unless the hedge has been traded but not settled at period end. If this is the case, the fair value is calculated at the rate at which the hedge is being settled.
	3)	The fair value of forward interest rate swap contracts is based upon a valuation model that uses relevant observable market inputs at quoted intervals, such as forward yield curves, and is adjusted for Zebra’s own credit risk and the interest rate swap terms.

Investments and Marketable Securities	'
	Note 3 – Investments and Marketable Securities
	Investments in marketable debt securities are classified based on intent and ability to sell the investment securities. We intend to use Zebra’s available-for-sale securities to fund future acquisitions and other operating needs and therefore may be sold prior to maturity. Investments in marketable debt securities for which Zebra intends to sell within the next year are classified as current and those that we intend to hold in excess of one-year are classified as non-current.
	Changes in the market value of available-for-sale securities are reflected in the “Accumulated other comprehensive loss” caption of stockholders’ equity in the balance sheet, until we dispose of the securities. Once these securities are disposed of, either by sale or maturity, the accumulated changes in market value are transferred to investment income. On the statement of cash flows, changes in the balances of available-for-sale securities are shown as purchases, sales and maturities of investments and marketable securities under investing activities.
	Changes in market value of trading securities would be recorded in investment income as they occur, and the related statement of cash flows would include changes in the balances of trading securities as operating cash flows.
	Included in Zebra’s cash and investments and marketable securities are amounts held by foreign subsidiaries which are generally invested in U.S. dollar-denominated holdings. Zebra had foreign cash and investments of $330,895,000 as of September 27, 2014, and $251,658,000 as of December 31, 2013. Amounts held by foreign subsidiaries are generally subject to U.S. income taxation upon repatriation. Zebra does not see a need to repatriate these funds.

	Zebra had goodwill of $153,515,000 as of September 27, 2014 and $155,800,000 as of December 31, 2013.
	In the fourth quarter 2013, Zebra acquired all of the outstanding membership interests in Hart Systems, LLC (a New York limited liability company) with $60,858,000 of the purchase price allocated to goodwill. As of September 27, 2014 the purchase price allocation was finalized and the amount of goodwill was reduced to $58,573,000 for adjustments related to deferred taxes. This acquisition is considered a separate reporting unit for purposes of Zebra’s goodwill impairment test.
	We test goodwill for impairment on an annual basis or more frequently if we believe indicators of impairment exist. We performed our assessment in accordance with Accounting Standards update (ASU) 2011-08, which allows for the option to make a qualitative evaluation about the likelihood of goodwill impairment to determine whether the fair value needs to be reassessed. We performed our qualitative assessment, which excluded Hart Systems, LLC, as of May 24, 2014 and determined that our goodwill was not impaired. Impairment testing for Hart Systems, LLC will occur in the fourth quarter of this year.

Derivative Instruments and Hedging Activities Disclosure [Abstract]	'
Derivative Instruments	'
	Note 9 – Derivative Instruments
	Portions of our operations are subject to fluctuations in foreign exchange rates. We manage these risks using derivative financial instruments. We conduct business on a multinational basis in a wide variety of foreign currencies. Our exposure to market risk for changes in foreign currency exchange rates arises from international financing activities between subsidiaries, foreign currency denominated monetary assets and liabilities and transactions arising from international trade. Our objective is to preserve the economic value of non-functional currency denominated cash flows. We attempt to hedge transaction exposures with natural offsets to the fullest extent possible and, once these opportunities have been exhausted, through foreign exchange forward and option contracts with third parties.
	In addition, we have exposure to market risk for changes in interest rates resulting from the announced acquisition of the Enterprise business of Motorola Solutions, Inc. In June 2014, we entered into a commitment letter for a new variable rate credit facility to fund the announced acquisition and we also entered into two tranches of floating-to-fixed forward interest rate swaps to hedge the interest rate risk. In July 2014, we designated these forward interest rate swaps as cash flow hedges of interest rate exposure associated with variability in future cash flows on our variable rate commitment. Changes in fair value of the forward interest rate swaps that are effective at offsetting variability in the future cash flows are recognized in other comprehensive income (loss). Ineffectiveness is immediately recognized in earnings.
	The fair value of the forward interest rate swap contracts is estimated using market quoted forward interest rates for the London Interbank Offered Rate “LIBOR” at the balance sheet date and the application of such rates subject to the interest rate swap terms. In accordance with ASC 815 we recognize derivative instruments and hedging activities as either assets or liabilities on the balance sheet and measure them at fair value. Gains and losses resulting from changes in fair value are accounted for depending on the use of the derivative and whether it is designated as and qualifies for hedge accounting.
	Credit and Market Risk
	Financial instruments, including derivatives, expose us to counterparty credit risk for nonperformance and to market risk related to interest and currency exchange rates. We manage our exposure to counterparty credit risk through specific minimum credit standards, diversification of counterparties, and procedures to monitor concentrations of credit risk. Our counterparties in derivative transactions are commercial banks with significant experience using derivative instruments. We monitor the impact of market risk on the fair value and cash flows of our derivative and other financial instruments considering reasonably possible changes in interest rates and currency exchange rates and restrict the use of derivative financial instruments to hedging activities. We continually monitor the creditworthiness of our customers to which we grant credit terms in the normal course of business.
	Fair Value of Derivative Instruments
	Zebra has determined derivative instruments for hedges that have traded but have not settled are considered Level 1 in the fair value hierarchy, and hedges that have not traded are considered Level 2 in the fair value hierarchy. Derivative instruments are used to manage risk and are not used for trading or other speculative purposes, nor do we use leveraged derivative financial instruments. Our foreign currency exchange and forward interest-rate swap contracts are valued using broker quotations or market transactions in either the listed or over-the-counter markets.
	Hedging of Net Assets
	We use forward contracts to manage exposure related to our pound and euro denominated net assets. Forward contracts typically mature within three months after execution of the contracts. We record gains and losses on these contracts in income each quarter along with the transaction gains and losses related to our net asset positions, which would ordinarily offset each other.
	Summary financial information related to these activities included in our consolidated statement of earnings as other income (expense) is as follows (in thousands):

	Net fair value of outstanding contracts	$	(135	)	$	33
	Hedging of Anticipated Sales
	We manage the exchange rate risk of anticipated euro-denominated sales using purchased options, forward contracts, and participating forwards. We designate these contracts as cash flow hedges which mature within twelve months after the execution of the contracts. Gains and losses on these contracts are deferred in other comprehensive income until the contracts are settled and the hedged sales are realized. The deferred gains or losses will then be reported as an increase or decrease to sales.

	Forward Interest Rate Swaps
	The forward interest rate swaps hedge the interest rate risk associated with the variable rate commitment entered into for the announced acquisition of the Enterprise business of Motorola Solutions, Inc.
	These forward interest rate swaps were used to economically hedge interest rate risk associated with the variable rate commitment until July 30, 2014, and as such, changes in their fair value were recognized in earnings in other income (expense). Effective July 30, 2014, these forward interest rate swaps were designated as cash flow hedges of interest rate exposure associated with variability in future cash flows on the variable rate commitment. Subsequent to the hedge designation, the effective portion of changes in their fair value is recognized in other comprehensive income (loss) and the ineffective portion is recognized in earnings in other income (expense). The effective portion recognized in other comprehensive income (loss) will be reclassified to earnings as interest expense in other income (expense) as the interest payments under the committed variable rate credit facility affect earnings.
	The location of the forward interest rate swaps designated in a hedge relationship is as follows (in thousands):

No gain (loss) was reclassified from accumulated other comprehensive income (loss) into earnings on the forward interest rate swaps designated in a hedging relationship during the three months and nine months ended September 27, 2014.
At September 27, 2014, we expect that approximately $1,077,980 in losses on the forward interest rate swaps designated in a hedging relationship will be reclassified from accumulated other comprehensive loss into earnings during the next 12 months.

	Cash flows resulting from the tax benefits from tax deductions in excess of the compensation cost recognized (excess tax benefits) are classified as financing cash flows in the statement of cash flows. The tax benefits classified as financing cash flows for the nine months ended September 27, 2014 were $5,779,000 and for the nine months ended September 28, 2013 were $4,170,000.
	The fair value of share-based compensation is estimated on the date of grant using a binomial model. Volatility is based on an average of the implied volatility in the open market and the annualized volatility of Zebra stock prices over our entire stock history. Stock option grants in the table below include both stock options, all of which were non-qualified, and stock appreciation rights (SARs) that will be settled in Zebra stock. Restricted stock grants are valued at the market closing price on the date of the grant.

	The terms of the SARs are established under either the 2006 Incentive Compensation Plan or the 2011 Long-term Incentive Plan (the “Plans”) and the applicable SAR agreement. Once vested, a SAR entitles the holder to receive a payment equal to the difference between the per-share grant price of the SAR and the fair market value of a share of Zebra stock on the date the SAR is exercised, multiplied by the number of SARs exercised. Exercised SARs are settled in whole shares of Zebra stock, and any fraction of a share is settled in cash. The SARs granted typically vest annually in four equal amounts on each of the first four anniversaries of the grant date, with some SARs vesting over a period of five years. All SARs expire 10 years after the grant date.

	The terms of Zebra’s restricted stock grants are defined in the Plans and the applicable award agreements. Restricted grants consist of time vested restricted stock awards (RSA’s), restricted stock units (RSU’s) and performance share awards (PSA’s). Zebra’s restricted stock awards and units are expensed over the vesting period of the related award, typically three to five years. Compensation cost is calculated as the market date fair value on the grant date multiplied by the number of shares granted. Restricted stock units of 8,992 were granted in the first nine months of 2014.

Note 15 – Income Taxes

Zebra has identified, evaluated, and measured the amount of income tax benefits to be recognized for all of our income tax positions. Included in deferred tax assets are amounts related to federal and state net operating losses that resulted from our acquisition of WhereNet Corp in 2007. We intend to utilize these net operating loss carryforwards to offset future income taxes prior to expiration. Under the United States Tax Reform Act of 1986, the amount of benefits from net operating loss carryforwards may be impaired or limited in certain circumstances, including significant changes in ownership interests. The company has reviewed the impact of ownership changes and believes that this will not have an impact on the realizability on the related deferred tax asset recorded as of September 27, 2014.

Zebra earns a significant amount of our operating income outside of the U.S., which is deemed to be permanently reinvested in foreign jurisdictions. We do not intend to repatriate funds nor do we need to fund U.S. operations. Repatriation would result in higher effective tax rates.

In 2014, we completed an audit of the 2011 and 2012 US Federal income tax returns with no material impact on the financial statements. Various tax years remain open to examination by multiple state taxing jurisdictions. Tax authorities in the United Kingdom have completed income tax audits for tax years through 2011 with no material impact on the financial statements.

At September 27, 2014 Zebra’s unrealized tax benefit was $4,000. Zebra’s continuing practice is to recognize interest and/or penalties related to income tax matters as part of income tax expense. For the nine months ended September 27, 2014 and September 28, 2013, we did not accrue any interest or penalties into income tax expense.

The effective income tax rate for the first nine months of 2014 was 23.1% compared with 18.4% for 2013. The change in the tax rate was driven by a change in the UK tax laws related to intercompany debt which resulted in a one-time charge of $5,900,000 and additional tax expense for the current quarter of $2,600,000 during Q3. We expect this charge to be reversed in the fourth quarter as a result of the issuance of the Motorola Enterprise acquisition debt. See Notes 18 for details. In addition, the third quarter rate was decreased by the significant acquisition expenses incurred primarily in the United States.

Equity [Abstract]	'
Other Comprehensive Income	'
	Note 16 – Other Comprehensive Income
	Stockholders’ equity includes certain items classified as accumulated other comprehensive income (AOCI), including:
		•		Unrealized gains (losses) on anticipated sales hedging transactions relate to derivative instruments used to hedge the currency exchange rates for forecasted euro sales and interest rates on variable rate commitments. These hedges are designated as cash flow hedges, and we have deferred income statement recognition of gains and losses until the hedged transaction occurs. See Note 9 for more details.
		•		Unrealized gains (losses) on forward interest rate swap hedging transactions refers to the hedging of the interest rate risk associated with the variable rate commitment entered into for the acquisition of the Enterprise business of Motorola Solutions, Inc. See Note 9 for more details.
		•		Unrealized gains (losses) on investments are deferred from income statement recognition until the gains or losses are realized.
		•		Foreign currency translation adjustment relates to our non-U.S. subsidiary companies that have designated a functional currency other than the U.S. dollar. We are required to translate the subsidiary functional currency financial statements to dollars using a combination of historical, period-end, and average foreign exchange rates. This combination of rates creates the foreign currency translation adjustment component of other comprehensive income.

	In May 2014, the FASB issued update 2014-09, ASC 606, Revenue from Contracts with Customers. This guidance is a comprehensive new revenue recognition model that requires a company to recognize revenue to depict the transfer of goods or services to a customer at an amount that reflects the consideration it expects to receive in exchange for those goods or services. This standard is effective for annual periods beginning after December 15, 2016 and interim periods within those annual periods. Management is still assessing the impact of adoption on its consolidated financial statements.

	Private Offering & New Credit Facilities
	On October 15, 2014, Zebra completed its previously announced private offering of $1.05 billion aggregate principal amount of 7.25% Senior Notes due 2022 (the “Notes”). The Notes are governed by the terms of an indenture, dated as of October 15, 2014, by and among Zebra and U.S. Bank National Association, as trustee. Interest on the Notes will be payable in cash on April 15 and October 15 of each year, commencing on April 15, 2015.
	On October 27, 2014, Zebra entered into a new credit agreement which provides for a term loan of $2.2 billion (the “Term Loan”) and a revolving credit facility of $250.0 million (the “Revolving Credit Facility”). Zebra is required to make scheduled quarterly payments each equal to 0.25% of the original principal amount of the Term Loan, with the balance due on the seventh anniversary of the closing date of the Acquisition (see below for further description of this acquisition). The Term Loan accrues interest at a variable rate of LIBOR (subject to a floor of 0.75% per annum) plus a margin of 4.0%.
	Certain domestic subsidiaries of Zebra (the “Guarantors”) guarantee the Notes, the Term Loan and the Revolving Credit Facility on a senior unsecured basis beginning on the date of close of the acquisition of the Enterprise Business (see below for further description of this acquisition).
	The indenture governing the Notes and the agreements governing Zebra’s other indebtedness impose certain operating and financial restrictions on our activities. Zebra will be required, during certain periods where outstanding revolving loans under the Revolving Credit Facility exceed a certain threshold, to maintain a total secured net leverage ratio calculated pursuant to a financial maintenance covenant under the senior credit agreement governing the Revolving Credit Facilities.
	Business Combination
	On October 27, 2014, Zebra completed its acquisition of the Enterprise Business under the terms of the previously announced Acquisition Agreements with Motorola Solutions Inc. (“MSI”) for a preliminary purchase price of $3.45 billion. This acquisition will transform Zebra into a leading provider of solutions that deliver greater intelligence and insights into our customers’ enterprises and extending value chains. The Enterprise Business will generate significant value for our shareholders by driving further product innovation and deeper engagement with our customers and partners. It positions Zebra as a leading technology innovator, with the accelerating convergence of mobility, data analytics and cloud computing. This transaction will enable Zebra to further sharpen its strategic focus on providing mission-critical solutions for its customers. On April 14, 2014, Zebra entered into the Acquisition Agreements with MSI pursuant to which we agreed to acquire the Enterprise Business. Certain assets historically associated with the Enterprise Business have been retained by MSI, including MSI’s iDEN infrastructure business, and other assets and certain liabilities as specified by the definitive agreement. The acquisition is structured as a combination of stock and asset sales and a merger of certain US entities, resulting in 100% ownership of the Enterprise Business.
	At the closing of the Acquisition, the Term Loan was drawn in full and the Revolving Credit Facility remained undrawn. The proceeds from the Notes and Term Loan together with cash on hand were used to finance the Acquisition and related fees and expenses.
	The final determination of the purchase price allocation is expected to be completed as soon as practicable after consummation of the Acquisition. Due to the limited time between the acquisition date and the filing of this Quarterly Report on Form 10-Q, it is not practicable for Zebra to disclose: (i) the allocation of purchase price to assets acquired and liabilities assumed as of the date of close, and (ii) pro forma revenues and earnings of the combined company for the period ended September 27, 2014.
	Tax Event
	During 2012, Zebra established a foreign holding company and restructured the structure of its foreign affiliates. The new structure introduced leverage which favorably impacted Zebra’s effective tax rate and the Company recorded a benefit of $5,900,000 during the first two quarters of 2014. However, due to the change in UK tax law, the Company has recorded a charge of $5,900,000 in the third quarter of 2014. As a result of the acquisition transaction of the Enterprise business of Motorola Solutions, Inc. closing on October 27, 2014, the Company will reverse this income tax charge in the fourth quarter of 2014. In addition, since the company did not record a benefit from interest expense in the third quarter, the related benefit of $2,600,000 will be recorded in the fourth quarter in addition to the benefit from fourth quarter interest expense.

		a.	Fair value of a collar or put option contract associated with forecasted sales hedges are calculated using bid and ask rates for similar contracts.
		b.	Fair value of regular forward contracts associated with forecasted sales hedges are calculated using the period-end exchange rate adjusted for current forward points.
		c.	Fair value of balance sheet hedges are calculated at the period end exchange rate adjusted for current forward points unless the hedge has been traded but not settled at period end. If this is the case, the fair value is calculated at the rate at which the hedge is being settled.
	3)	The fair value of forward interest rate swap contracts is based upon a valuation model that uses relevant observable market inputs at quoted intervals, such as forward yield curves, and is adjusted for Zebra’s own credit risk and the interest rate swap terms.
