	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, 2012.
	The consolidated balance sheet as of December 31, 2012, 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 28, 2013, the consolidated statements of earnings for the three and nine months ended September 28, 2013 and September 29, 2012, and consolidated statements of comprehensive income for the three and nine months ended September 28, 2013 and September 29, 2012, and the consolidated statements of cash flows for the nine months ended September 28, 2013 and September 29, 2012. These results, however, are not necessarily indicative of results for the full year.

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 28, 2013, 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 28, 2013. 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.
	The decline in the market value of our auction rate security discussed above is considered temporary and has been recorded in accumulated other comprehensive income (loss) on Zebra’s balance sheet. Since Zebra has the intent and ability to hold this auction rate security until it is sold, we have classified it as a long-term investment on the balance sheet.

	2)	The fair value of forward contracts is 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.

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 further 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 $232,187,000 as of September 28, 2013, and $173,483,000 as of December 31, 2012. Amounts held by foreign subsidiaries are generally subject to U.S. income taxation upon repatriation, however, Zebra does not see a need to repatriate these funds.

	Zebra has $94,942,000 of goodwill recorded as of September 28, 2013 and December 31, 2012.
	We test goodwill for impairment on an annual basis or more frequently if we believe indicators of impairment exist. We perform 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. Zebra has two reporting units for its annual goodwill impairment test, however only one includes a goodwill balance. Based on an analysis of various qualitative and quantitative factors, we determined that it was not more likely that the fair value of the reporting unit was less than its carrying value, including goodwill. We performed our qualitative assessment in June 2013 and determined that our goodwill was not impaired as of the end of May 2013.
	In the third quarter 2012, due to the deterioration in the smaller reporting unit’s operating results, our fair value calculation for the smaller reporting unit changed and we determined our goodwill associated with the smaller reporting unit to be impaired. As a result, Zebra performed a second step analysis and recorded a goodwill impairment charge of $9,114,000 as of September 29, 2012. After this impairment charge, there was no remaining goodwill in the smaller reporting unit.
	In the third quarter 2012, Zebra acquired all of the outstanding membership interests in Laserband LLC (a Missouri limited liability company) with $24,353,000 of the purchase price allocated to goodwill.
	Changes in the net carrying value amount of goodwill were as follows (in thousands):

Costs Associated with Exit and Restructuring Activities	'
	Note 7 – Costs Associated with Exit and Restructuring Activities
	In December 2012, we began a plan, “2012 restructuring plan” to restructure our Location Solutions business management structure. We also announced a project to further optimize our manufacturing operations, which includes the consolidation and relocation of support functions.
	During the third quarter of 2012, revenue from our Location Solutions business fell below plan, because of slower than anticipated shipments to the automotive and process manufacturing industries, and weakness in sales to the government sector. As a result, we initiated the Locations Solutions 2012 restructuring plan.
	In the second quarter of 2013 management determined that additional restructuring actions would be required to meet our financial goals for the Location Solutions business.
	During 2007, Zebra began a plan to outsource printer manufacturing to a third-party manufacturer. We completed the conversion to outsourcing in 2010. During the fourth quarter of 2012, we determined that further supply chain cost reductions were possible by moving certain supply chain support operations closer to the contract printer manufacturing facility, which is located in China.
	The costs below incurred through December 31, 2012, represent the costs related to the restructuring of our Location Solutions business management structure. Costs incurred for 2013 and costs expected to be incurred relate to the following: restructuring of Zebra’s manufacturing operations; relocation of a significant portion of Zebra’s supply chain operations from the U.S. to China; consolidating activities domestically; restructuring of our sales operations; restructuring certain corporate functions; and amending the Location Solutions “2012 restructuring plan” by adding additional restructuring charges to be incurred.
	There were no exit and restructuring costs for the three and nine months ended September 29, 2012. Exit and restructuring costs for 2013 are as follows:

Derivative Instruments And Hedging Activities Disclosure [Abstract]	'
Derivative Instruments	'
	Note 8 – Derivative Instruments
	Portions of our operations are subject to fluctuations in currency exchange rates. We manage these risks using derivative financial instruments. We conduct business on a multinational basis in a variety of foreign currencies. Our exposure to market risk for changes in currency exchange rates arises from international financing activities between subsidiaries, monetary assets and liabilities denominated in non-functional foreign currencies and transactions arising from international trade. Our objective is to preserve the economic value of non-functional currency denominated cash flows and balances. We attempt to hedge transaction exposures with natural offsets to the extent possible and, once these opportunities have been exhausted, through foreign exchange forward and option contracts with third parties.
	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 by requiring counterparties to maintain specific minimum credit standards, diversifying our business among several counterparties, and maintaining procedures to monitor concentrations of credit risk. Our counterparties in derivative transactions are commercial banks with significant experience trading 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. In addition, we regularly monitor the creditworthiness of our customers to which we grant credit terms in the normal course of business. The terms and conditions of our credit sales are designed to mitigate or eliminate concentrations of credit risk with any single customer.
	Fair Value of Derivative Instruments
	Zebra has determined that 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 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 British 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. The gains and losses of our forward contracts are designed to offset the gains and losses of our net asset positions.

	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 “Accumulated other comprehensive loss” until the contracts are settled and the hedged sales are realized. The deferred gains or losses are then reported as an increase or decrease to sales.

	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.

Note 14 – 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 acquired as part of our acquisition of WhereNet Corporation in 2007. We intend to utilize these net operating loss carryforwards to offset future income taxes.

Zebra earns a significant amount of its operating income outside of the U.S., which is deemed to be permanently reinvested in foreign jurisdictions. We do not intend to repatriate funds. Repatriation would result in higher effective tax rates. Borrowing in the U.S. would result in increased interest expense.

An audit of U.S. federal tax returns for years 2008 through 2010 was completed in 2012. The Internal Revenue Service is currently in the process of auditing the 2011 federal return. The tax years 2010 through 2012 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.

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 28, 2013 and September 29, 2012, we did not accrue any interest or penalties into income tax expense.

The effective income tax rate for the first nine months of 2013 was 18.4% compared with 27.5% which reflects a discrete item for a nondeductible asset impairment charge increasing the effective tax rate by 2.0% for the first nine months of 2012. The 2013 effective tax rate reflects higher profits in lower-rate international jurisdictions in addition to 9 months of tax benefits derived from tax planning income tax strategies put into place during the second half of 2012. In addition, the US R&D credit reinstatement for the 2012 income tax year resulted in a tax benefit of $400,000 recorded in the first quarter. In addition, as a result of filing the 2012 federal income tax return during the third quarter, we recorded a onetime income tax benefit in the amount of $715,000 or a reduction of 1.5% related to differences between the income tax provision and the actual return that was filed.

	Note 15 – Other Comprehensive Income
	Stockholders’ equity includes certain items classified as accumulated other comprehensive income (AOCI), including:
		•		Unrealized gains (losses) on hedging transactions relate to derivative instruments used to hedge the currency exchange rates for forecasted euro sales. 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 8 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.
