Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation	Basis of Presentation The condensed consolidated financial statements as of September 29, 2018 and for the three and nine months ended September 29, 2018 and September 30, 2017 include, in the opinion of management, all adjustments (consisting of normal recurring adjustments and reclassifications) necessary to present fairly the condensed consolidated balance sheets, statements of operations, statements of comprehensive income, statement of stockholders' equity, and statements of cash flows of Motorola Solutions, Inc. (“Motorola Solutions” or the “Company”) for all periods presented. Certain information and footnote disclosures normally included in financial statements prepared in accordance with U.S. generally accepted accounting principles (“U.S. GAAP”) have been condensed or omitted. These condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and notes thereto included in the Company’s Form 10-K for the year ended December 31, 2017 . The results of operations for the three and nine months ended September 29, 2018 are not necessarily indicative of the operating results to be expected for the full year. The preparation of financial statements in conformity with U.S. GAAP requires management to make certain estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting periods. Actual results could differ from those estimates. During the second quarter of 2018, the Company modified its internal reporting structure to better align the way financial information is reported to and analyzed by executive leadership, in part, as a result of recent acquisitions contributing to the growth within the newly aligned Services and Software segment. Previously, the Company had two reporting segments: Products and Services. The changes in reporting structure consist of Systems Integration related revenue and costs moving from the old Services segment into the newly presented Products and Systems Integration segment and Software related revenue and costs moving from the old Products segment into the newly presented Services and Software segment. Recent Developments On March 28, 2018, the Company completed the acquisition of Avigilon Corporation ("Avigilon"), a provider of advanced end-to-end security and surveillance solutions including video analytics, network video management hardware and software, surveillance cameras and access control solutions for a purchase price of $974 million . On March 7, 2018, the Company completed the acquisition of Plant Holdings, Inc. ("Plant"), the parent company of Airbus DS Communications for a purchase price of $237 million . This acquisition expands our software portfolio in the command center with additional solutions for Next Generation 9-1-1. Recent Accounting Pronouncements In February 2016, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") No. 2016-02, "Leases," which amends existing guidance to require lessees to recognize assets and liabilities on the balance sheet for the rights and obligations created by long-term leases and to disclose additional quantitative and qualitative information about leasing arrangements. The ASU is effective for the Company on January 1, 2019 and interim periods within that reporting period, with early adoption permitted. In July 2018, the FASB issued ASU 2018-11 that amended the ASU to include an additional (and optional) transition relief. The additional transition relief provides entities the option to adopt the ASU by applying the new ASU at the adoption date and recognizing a cumulative-effect adjustment to the opening balance of retained earnings in the period of adoption without restatement of comparative periods. The new ASU must be adopted utilizing the modified retrospective method as of the earliest comparative period presented if the optional adoption method is not selected. The Company will adopt the ASU on January 1, 2019, utilizing the modified retrospective method as of the adoption date. The Company is continuing to assess the impact of the ASU on its condensed consolidated financial statements, including the package of available practical expedients, required disclosures, and changes to internal controls. Based on the preliminary work completed, the Company expects a material impact to its condensed consolidated balance sheet through the recording of right-of-use assets and lease obligations that are not required to be recorded within the condensed consolidated balance sheet under current accounting standards. In June 2016, the FASB issued ASU No. 2016-13, “Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments,” which requires entities to estimate and recognize current expected credit losses rather than delay recognition of credit losses until the loss is probable of occurring. The ASU is effective for the Company on January 1, 2020, and interim periods within that reporting period with early option permitted. The Company is currently evaluating the impact of the ASU on its consolidated financial statements and disclosures. In August 2017, the FASB issued ASU No. 2017-12, "Derivatives and Hedging (Topic 815): Targeted Improvements to Accounting for Hedging Activities," which is intended to simplify the application of hedge accounting and better portray the economic results of risk management strategies in the consolidated financial statements. The ASU expands and refines hedge accounting for both financial and non-financial risk components, aligns the recognition and presentation of the effects of hedging instruments and hedge items in the financial statements, and includes certain targeted improvements to ease the application of current guidance related to the assessment of hedge effectiveness. The ASU is effective for the Company on January 1, 2019 with adoption permitted immediately in any interim or annual period (including the current period). The guidance related to cash flow and net investment hedges existing at the date of adoption should be applied using the modified retrospective method by means of a cumulative-effect adjustment to the balance sheet as of the beginning of the fiscal year of adoption. The guidance related to presentation and disclosure should be applied prospectively. The Company is currently assessing the impact of this ASU, including transition elections and required elections, on its consolidated financial statements and disclosures. In August 2018, the FASB issued ASU No. 2018-14, “Compensation - Retirement Benefits - Defined Benefit Plans - General (Subtopic 715-20) - Changes to the Disclosure Requirements for Defined Benefit Plans,” which modifies the disclosure requirements for the defined benefit pension plans and other postretirement plans. The ASU is effective for the Company on January 1, 2020 with early adoption permitted. The ASU requires a retrospective adoption method. The Company does not believe the ASU will have a material impact on its financial statement disclosures. Recently Adopted Accounting Pronouncements The Company adopted ASU No. 2016-16, “Accounting for Income Taxes: Intra-Entity Asset Transfers of Assets Other than Inventory” on January 1, 2018 using the modified retrospective method of adoption. The Company recognized $31 million related to the cumulative effect of applying the ASU as an adjustment to its opening retained earnings balance. The comparative information has not been restated and continues to be reported under accounting standards in effect in those periods. This ASU eliminates the prior application of deferring the income tax effect of intra-entity asset transfers, other than inventory, until the transferred asset is sold to a third party or otherwise recovered through use. Under the ASU, the Company will recognize tax expense when intra-entity transfers of assets other than inventory occur. The Company adopted ASU No. 2017-07, “Compensation - Retirement Benefits (Topic 715) - Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost” on January 1, 2018 using the retrospective method of adoption. The amendments in the ASU require that an employer disaggregate the service cost component from the other components of net periodic cost (benefit) and report that component in the same line item as other compensation costs arising from services rendered by employees during the period. The other components of net periodic cost (benefit) are required to be presented in the statement of operations separately from the service cost component and outside of operating earnings. The Company has restated its comparative period results to reflect the application of the presentation guidance of the ASU. As a result of the ASU, the presentation of net periodic cost (benefit) has been updated to classify all components of the Company’s net periodic benefit, with the exception of the service cost component, within Other in Other income (expense) on the statement of operations. The Company reclassified $18 million and $10 million in the three months ended September 29, 2018 and September 30, 2017 , respectively, and $58 million and $10 million in the nine months ended September 29, 2018 and September 30, 2017 , respectively. The Company adopted ASU No. 2014-09, "Revenue from Contracts with Customers," and all the related amendments (collectively “ASC 606”) on January 1, 2018 using the modified retrospective method. The Company recognized the cumulative effect of initially applying the new revenue standard as an adjustment to its opening retained earnings. The comparative information has not been restated and continues to be reported under the accounting standards in effect in those periods. The Company has retained much of the same accounting treatment used to recognize revenue under ASC 606 as under accounting standards in effect in prior periods. Revenue on a significant portion of its System and Integration services contracts continues to be recognized under percentage of completion accounting, applying a cost-to-cost method. Services contracts continue to be recognized ratably over relevant contract terms as the Company stands ready to perform. Finally, revenue on equipment sales continues to be recognized based on delivery terms as aligned with the transfer of control. Under the new standard, the Company identified distinct promises to transfer goods and services within its contracts. For system contracts that are recognized under percentage of completion accounting, the Company has considered the factors used to determine whether promises made in the contract are distinct and determined that devices and accessories represent distinct goods. Accordingly, adoption of the new standard impacts the Company's system contracts, with the result being revenue recognized earlier as control of devices and accessories transfers to the customer at a point in time rather than over time. For the remaining promised goods and services within the Company's system contracts, it continues to recognize revenue on these contracts using a cost-to-cost method based on the continuous transfer of control to the customer over time. Under the new standard, revenue recognition for software sales is accelerated based on when control of software licenses and related support services are transferred to the customer. Amounts deferred under previous software accounting rules due to lack of vendor-specific objective evidence have been recognized as an adjustment through opening retained earnings. Historically, the Company presented transactions that involved a third-party sales representative on a net basis. After considering the control concept and the remaining three indicators of gross presentation under the new standard, the Company has determined that it is the principal in contracts that involve a third-party sales representative. Thus, under the new standard, the Company presents associated revenues on a gross basis, with the affect being an equal increase to selling, general and administrative expenses for its cost of third-party commissions. Under prior accounting standards, the Company expensed sales commissions and other costs to obtain a contract as incurred. However, under the new standard, the Company capitalizes sales commissions and certain other costs as incremental costs to obtain a contract. Such costs are classified as non-current contract cost assets within Other assets and amortized over a period that approximates the timing of revenue recognition on the underlying contracts. The new standard clarified the definition of a receivable and requires the Company to present its net position in a contract with a customer on the balance sheet. The position is presented as either a receivable, contract asset, or a contract liability. Under the new definition, accounts receivable are unconditional rights to consideration from a customer. Contract assets represent rights to consideration from a customer in exchange for transferred goods and services that are conditional on events other than the passage of time. Contract liabilities represent obligations to transfer goods and services for which the Company has received, or is due, consideration from a customer. The Company reclassified its customer positions to align with the new definitions and presentation guidance. Accordingly, Unbilled accounts receivable and Costs and earnings in excess of billings have been reclassified from Accounts receivable and Other current assets, respectively, and are presented as Contract assets. Accounts receivable which are not due from customers have been reclassified into Other current assets. Deferred revenue, Billings in excess of costs and earnings, and Customer downpayments have been reclassified from Accrued liabilities and are presented as Contract liabilities. Non-current deferred revenue has been reclassified from Deferred revenue to Non-current contract liabilities within Other liabilities.

Revenue from Contract with Customer [Abstract]
Revenue from Contracts with Customers	Revenue from Contracts with Customers In accordance with ASC 606, the Company recognizes revenue to reflect the transfer of control of promised goods or services to customers in an amount that reflects the consideration to which the Company expects to be entitled in exchange for goods or services. The Company records revenue following the five steps below: 1. Identify the contract with customers: A contract is an agreement between two or more parties that creates enforceable rights and obligations and specifies that enforceability is a matter of law. Contracts shall be accounted for when: (i) the parties to the contract have approved the contract (in writing, orally, or in accordance with other customary business practices) and are committed to perform their respective obligations, (ii) the Company can identify each party’s rights regarding the goods or services to be transferred, (iii) the Company can identify the payment terms for the goods or services to be transferred, (iv) the contract has commercial substance (that is, the risk, timing, or amount of the Company’s future cash flow is expected to change as a result of the contract), and (v) it is probable that the Company will collect substantially all of the consideration to which it will be entitled in exchange for the goods or services that will be transferred to the customer. It is the Company’s customary business practice to obtain a signed legal document as evidence of an arrangement. 2. Identify performance obligations in contracts: The goods or services promised in a contract must be evaluated at inception to identify as a performance obligation each promise to transfer to the customer either: (i) a distinct good or service, or (ii) a series of distinct goods or services that are substantially the same and that have the same pattern of transfer to the customer. 3. Determine the transaction price: The transaction price is the amount of consideration to which the Company expects to be entitled in exchange for transferring goods or services to a customer, excluding amounts collected on behalf of third parties. In determining the transaction price, the Company considers the following components: (i) variable consideration, (ii) significant financing, (iii) noncash consideration, and (iv) consideration payable to a customer. 4. Allocate the transaction price: For a contract that has more than one distinct performance obligation, the Company must allocate the transaction price to each distinct performance obligation in an amount that depicts the amount of consideration to which the Company expects to be entitled in exchange for satisfying that specific performance obligation. 5. Recognize revenue when or as the entity satisfies a performance obligation: The Company recognizes revenue when, or as, it satisfies a performance obligation by transferring control of a promised good or service to a customer. Disaggregation of Revenue The following table summarizes the disaggregation of our revenue by segment, geography, major product and service type and customer type for the three and nine months ended September 29, 2018 , consistent with the information reviewed by our chief operating decision maker for evaluating the financial performance of operating segments: Three Months Ended Nine Months Ended (in millions) Products and Systems Integration Services and Software Products and Systems Integration Services and Software Regions Americas $ 957 $ 343 $ 2,533 $ 969 EMEA 199 189 543 565 Asia Pacific 132 42 353 126 Total $ 1,288 $ 574 $ 3,429 $ 1,660 Major Products and Services Devices $ 828 $ — $ 2,184 $ — Systems and Systems Integration 460 — 1,245 — Services — 455 — 1,357 Software — 119 — 303 Total $ 1,288 $ 574 $ 3,429 $ 1,660 Customer Type Direct $ 811 $ 543 $ 2,168 $ 1,586 Indirect 477 31 1,261 74 Total $ 1,288 $ 574 $ 3,429 $ 1,660 Products and Systems Integration: The Products and Systems Integration segment is comprised of Systems, Devices and Systems Integration. Direct customers of the Products and Systems Integration segment are typically government, public safety and first-responder agencies, procuring at state, local, and federal levels as well as large commercial customers with secure mission-critical needs. Indirect customers are defined as customers purchasing professional commercial radios and Avigilon video solutions, which are primarily sold through the Company's reseller partners to an end-customer base, composed of various industries where private communications networks and video solutions are used to secure operations and enable a mobile workforce. Contracts with the Company's customers are typically fixed fee, with consideration measured net of associated sales taxes, and, as it relates to our direct customers, funded through government appropriations. On the Company's Products and Systems Integration sales, it records consideration from shipping and handling on a gross basis within Net sales. Devices: Devices includes two-way portable and vehicle-mounted radios, accessories, software features, and upgrades. Devices also includes video surveillance cameras sold by Avigilon. Devices are considered capable of being distinct and distinct within the context of our contracts. Revenue is recognized upon the transfer of control of the devices to the customer at a point in time, typically consistent with delivery under the applicable shipping terms. Devices are sold by both the direct sales force and through reseller partners. Revenue is generally recognized upon transfer of devices to reseller partners, rather than the end-customer, except for limited consignment arrangements. Provisions for returns and reseller discounts are made on a portfolio basis using historical data. Systems and Systems Integration: Systems and Systems Integration include customized end-to-end radio network, video solutions and implementation, optimization, and integration of networks, devices, software, and applications. Radio network includes the aggregation of promises to the customer to provide the radio network core and central processing software, base stations, consoles, and repeaters. These individual promises are not distinct in the context of the contract, as the Company provides a significant service of integrating and customizing the goods and services promised. The radio network represents distinct performance obligations for which revenue is recognized over time, as the Company creates an asset with no alternative use and has an enforceable right to payment for work performed. The Company's revenue recognition over time is based on an input measure of costs incurred, which depicts the transfer of control to its customers under its contracts. Systems and Systems Integration revenue is recognized over an average duration of approximately one to two years . Systems also include Avigilon end-to-end security and surveillance solutions including: video analytics, network video management hardware and software, and access control solutions, which are capable of being distinct and distinct in the context of the contract. Avigilon security and surveillance video solutions are traditionally sold through reseller partners, with contracts negotiated under fixed pricing. Provisions for returns are determined on a portfolio basis using historical data. Revenue is recognized upon the transfer of control of the end-to-end video solution to the reseller partners, typically upon shipment. Services and Software: The Services and Software segment provides a full set of offerings for government, public safety and commercial communication networks. Direct customers of the Services and Software segment are typically government, public safety and first-responder agencies and municipalities. Indirect customers are commercial customers who distribute broadband push-to-talk services to a final end customer base. Contracts with our customers are typically fixed fee, with consideration measured net of associated sales taxes, and, as it relates to our direct customers, funded through government appropriations. Services: Services includes a continuum of service offerings beginning with repair, technical support and maintenance. More advanced offerings include: monitoring, software updates and cybersecurity services. Managed service offerings range from partial to full operation of customer or Motorola Solutions owned networks. Services are provided across all radio network technologies. Services are both distinct and capable of being distinct in the context of the contract, representing a series of recurring services that the Company stands ready to perform over the contract term. Since services contracts typically allow for customers to terminate for convenience or for non-appropriations of fiscal funding, the contract term is generally considered to be limited to a monthly or annual basis, subject to customer renewal. While contracts with customers are typically fixed fee, certain managed services contracts may be subject to variable consideration related to the achievement of service level agreement performance measurements. The Company has not historically paid significant penalties under service level agreements, and accordingly, it does not constrain its contract price. Certain contracts may also contain variable consideration driven by number of users. Revenue is typically recognized on services over time as a series of services performed over the contract term on a straight-line basis. Software: Software offerings include public safety and enterprise command solutions, unified communications applications, and video software solutions delivered either “as a service” or on-premise. Solutions delivered as a service consist of a range of promises including hosted software, technical support and the right to unspecified future software enhancements. Software is not distinct from the hosting service since the customer does not have the right to take possession of the software at any time during the term of the arrangement. The hosted software, technical support, and right to unspecified future software enhancements each represent a series of distinct services that are delivered concurrently using the same over time method. As such, the promises are accounted for as a single performance obligation with revenue recognized on a straight-line basis. On-premise offerings consist of multiple promises primarily including software licenses and post-contract customer support. The promises are each distinct and distinct within the context of the contract as the customer benefits from each promise individually without any significant integration or interrelationship between the promises. On-premise software revenue is recognized at the point in time when the customer can benefit from the software which generally aligns with the beginning of the license period. Revenue for post-contract customer support is recognized over time as the customer simultaneously receives and consumes the services on a straight-line basis. Significant Judgments The Company enters into arrangements which consist of multiple promises to our customers. The Company evaluates whether the promised goods and services are distinct or a series of distinct goods or services. Where contracts contain multiple performance obligations, the Company generally allocates the total estimated consideration to each performance obligation based on applying an estimated selling price (“ESP”) as our best estimate of standalone selling price. The Company determines ESP by: (i) collecting all reasonably available data points including sales, cost and margin analysis of the product or services, and other inputs based on its normal pricing and discounting practices, (ii) making any reasonably required adjustments to the data based on market and Company-specific factors, and (iii) stratifying the data points, when appropriate, based on major product or service, type of customer, geographic market, and sales volume. The Company accounts for certain system contracts on an over time basis, electing an input method of estimated costs as a measure of performance completed. The selection of the measurement of progress using estimated costs was based on a thorough consideration of alternatives of various output and input measures, including contract milestones and labor hours. However, the Company has determined that other input and output measures are not an appropriate measure of progress as they do not accurately align with the transfer of control on its customized product solutions. The selection of costs incurred as a measure of progress aligns the transfer of control to the overall production of the customized system . For system contracts accounted for over time using estimated costs as a measure of performance completed, the Company relies on estimates around the total estimated costs to complete the contract (“Estimated Costs at Completion”). Total Estimated Costs at Completion include direct labor, material and subcontracting costs. Due to the nature of the efforts required to be performed to meet the underlying performance obligation, determining Estimated Costs at Completion may be complex and subject to many variables. We have a standard and disciplined quarterly process in which management reviews the progress and performance of open contracts in order to determine the best estimate of Estimated Costs at Completion. As part of this process, management reviews information including, but not limited to, any outstanding key contract matters, progress towards completion, the project schedule, identified risks and opportunities, and the related changes in estimates of costs. The risks and opportunities include management’s judgment about the ability and cost to achieve the project schedule, technical requirements, and other contract requirements. Management must make assumptions and estimates regarding labor productivity and availability, the complexity of work to be performed, the availability and cost of materials, and performance by subcontractors, among other variables. Based on this analysis, any quarterly adjustment to net sales, cost of sales, and the related impact to operating income are recorded as necessary in the period they become known. When estimates of total costs to be incurred on a contract exceed estimates of total revenue to be earned, a provision for the entire loss on the contract is recorded in the period in which the loss is determined. Remaining Performance Obligations Remaining performance obligations represent the revenue that is expected to be recognized in future periods related to performance obligations that are unsatisfied, or partially unsatisfied, as of the end of a period. The transaction price associated with remaining performance obligations which are not yet satisfied as of September 29, 2018 is $6.1 billion . A total of $3.3 billion is from Products and Systems Integration performance obligations that are not yet satisfied, of which $1.9 billion is expected to be recognized in the next 12 months . The remaining amounts will generally be satisfied over time as systems are implemented. A total of $2.8 billion is from Services and Software performance obligations that are not yet satisfied as of September 29, 2018 . The determination of Services and Software performance obligations that are not satisfied takes into account a contract term that may be limited by the customer’s ability to terminate for convenience. Where termination for convenience exists in the Company's Services contracts, its disclosure of the remaining performance obligations that are unsatisfied assumes the contract term is limited until renewal. The Company expects to recognize $1.2 billion from unsatisfied Services and Software performance obligations over the next 12 months , with the remaining performance obligations to be recognized over time as services are performed and software is implemented. Contract Balances (in millions) September 29, 2018 January 1, 2018 Receivables $ 1,179 $ 1,198 Contract assets 917 931 Contract liabilities 1,127 1,082 Non-current contract liabilities 159 162 Contract assets consist of amounts formerly classified as Costs and earnings in excess of billings and Unbilled accounts receivable where the Company does not yet have an unconditional right to bill. Contract liabilities consist of amounts formerly classified Billings in excess of costs and earnings recognized, Customer downpayments and Deferred revenue. Payment terms on system contracts are typically tied to implementation milestones associated with progress on contracts, while revenue recognition is over time based on a cost-to-cost method of measuring performance. The Company may recognize a contract asset or contract liability, depending on whether revenue has been recognized in excess of billings or billings in excess of revenue. Services contracts are typically billed in advance, generating Contract liabilities until the Company has performed the services. The Company does not record a financing component to contracts when it expects, at contract inception, that the period between the transfer of a promised good or service and related payment terms are less than a year. Revenue recognized during the three months ended September 29, 2018 which was previously included in Contract liabilities as of July 1, 2018 is $327 million . Revenue recognized during the nine months ended September 29, 2018 which was previously included in Contract liabilities as of January 1, 2018 is $777 million . Revenue of $7 million was reversed during the three months ended September 29, 2018 and $4 million of revenue was reversed during the nine months ended September 29, 2018 related to performance obligations satisfied, or partially satisfied, in previous periods, primarily driven by changes in the estimates of progress on system contracts. There have been no material impairment losses recognized on contract assets during the nine months ended September 29, 2018 . Contract Cost Balances (in millions) September 29, 2018 January 1, 2018 Current contract cost assets $ 57 $ 62 Non-current contract cost assets 95 85 Contract cost assets represent incremental costs to obtain a contract, primarily related to the Company's sales incentive plans, and certain costs to fulfill contracts. Contract cost assets are amortized into expense over a period that follows the passage of control to the customer over time. Incremental costs to obtain a contract with the Company's sales incentive plans are accounted for under a portfolio approach, with amortization ranging from one to four years to approximate the recognition of revenues over time. Where incremental costs to obtain a contract will be recognized in one year or less, the Company applies a practical expedient around expensing amounts as incurred. Amortization of contract cost assets was $11 million and $34 million for the three and nine months ended September 29, 2018 , respectively.

Organization, Consolidation and Presentation of Financial Statements [Abstract]
Other Financial Data	Other Financial Data Statements of Operations Information Other Charges (Income) Other charges (income) included in Operating earnings consist of the following: Three Months Ended Nine Months Ended September 29, September 30, September 29, September 30, Other charges: Intangibles amortization (Note 14) $ 46 $ 39 $ 140 $ 111 Reorganization of business (Note 13) 21 6 46 22 Environmental reserve expense 57 — 57 — Building impairment — — — 8 Loss (Gain) on legal settlements 2 — 3 (2 ) Gain on recovery of financial receivables — — — (42 ) Asset impairment — 2 — 2 Acquisition-related transaction fees — — 17 1 $ 126 $ 47 $ 263 $ 100 During the third quarter of 2018, the Company revised the estimate of a liability related to ongoing remediation efforts of environmental media such as groundwater, soil, and soil vapor, as well as related legal fees for a designated Superfund site under the Comprehensive Environmental Response, Compensation and Liability Act (commonly known as the “Superfund Act”) incurred by a legacy business. It is the Company’s policy to re-evaluate the reserve when certain events become known that will impact the future cash payments. During the third quarter of 2018, the Company became aware of additional remediation requirements for the Superfund site. As such, the Company recorded a charge of $57 million during the third quarter of 2018 which was primarily due to: (i) changes in the expected timeline of the remediation activities to 30 years and (ii) additional costs for further remediation efforts, increasing the reserve to $107 million . Given the timing and amount of the future cash payments are fixed or reliably determinable, the Company discounted the cash flows used in estimating this accrual using a risk-free treasury rate. The current portion of the estimated environmental liability is $4 million and is included in the “Accrued liabilities” statement line and the non-current portion is included in the “Other liabilities” statement line within the Company's Condensed Consolidated Balance Sheet. During the nine months ending September 29, 2018 , the Company recognized $17 million of acquisition-related transaction fees for the Avigilon and Plant acquisitions.

The loss on derivative instruments during the nine months ended September 29, 2018 , includes a loss of $14 million on foreign currency derivatives put in place to minimize the exposure to the Canadian dollar related to the purchase of Avigilon. During the three and nine months ended September 30, 2017 , the Company recognized foreign currency losses of $7 million and $29 million , respectively, primarily driven by British Pound, partially offset by gains of $3 million and $14 million , respectively, on derivative instruments put in place to minimize the foreign exchange risk related to currency fluctuations. Earnings Per Common Share The computation of basic and diluted earnings per common share is as follows: Amounts attributable to Motorola Solutions, Inc. common stockholders Three Months Ended Nine Months Ended September 29, September 30, September 29, September 30, Basic earnings per common share: Earnings $ 247 $ 212 $ 544 $ 420 Weighted average common shares outstanding 162.6 162.3 162.0 163.2 Per share amount $ 1.52 $ 1.30 $ 3.36 $ 2.57 Diluted earnings per common share: Earnings $ 247 $ 212 $ 544 $ 420 Weighted average common shares outstanding 162.6 162.3 162.0 163.2 Add effect of dilutive securities: Share-based awards 4.6 3.4 4.2 3.3 Senior Convertible Notes 5.4 3.3 5.4 2.8 Diluted weighted average common shares outstanding 172.6 169.0 171.6 169.3 Per share amount $ 1.43 $ 1.25 $ 3.17 $ 2.48 In the computation of diluted earnings per common share for the three months ended September 29, 2018 , the assumed exercise of 0.2 million options were excluded because their inclusion would have been antidilutive. For the nine months ended September 29, 2018 , the assumed exercise of 3.2 million options, including 0.8 million subject to market-based contingent option agreements, were excluded because their inclusion would have been antidilutive. For the three months ended September 30, 2017 , the assumed exercise of 2.0 million options, including 1.7 million subject to market-based contingent option agreements, were excluded because their inclusion would have been antidilutive. For the nine months ended September 30, 2017 , the assumed exercise of 2.3 million options, including 1.9 million subject to market-based contingent option agreements, were excluded because their inclusion would have been antidilutive. On August 25, 2015, the Company issued $1.0 billion of 2% Senior Convertible Notes which mature in September 2020 (the "Senior Convertible Notes"). The notes became fully convertible as of August 25, 2017. On September 5, 2018, the Company agreed with Silver Lake Partners to re-purchase $200 million principal of the convertible notes for aggregate consideration of $369 million in cash, inclusive of the conversion premium. During the third quarter of 2018, the Company paid $169 million , with the remaining $200 million paid on October 15, 2018. In the event of an additional conversion, the Company intends to settle the principal amount of the Senior Convertible Notes in cash. Since the Company’s intention is to settle the par value of the Senior Convertible Notes in cash upon conversion, only the number of shares that would be issuable (under the treasury stock method of accounting for share dilution) are included in our computation of diluted earnings per share. The conversion price is adjusted for dividends declared through the date of settlement. Diluted earnings per share has been calculated based upon the amount by which the average stock price exceeds the conversion price.

Debt and Credit Facilities

Debt and Credit Facilities	9 Months Ended
	Sep. 29, 2018
Debt Disclosure [Abstract]
Debt and Credit Facilities	Debt and Credit Facilities As of September 29, 2018 , the Company had a $2.2 billion syndicated, unsecured revolving credit facility scheduled to mature in April 2022 (the "2017 Motorola Solutions Credit Agreement"). As of March 31, 2018, the Company borrowed $400 million under the facility to complete the Avigilon acquisition. As of September 29, 2018 , the outstanding loan amount under the facility was $100 million , with $200 million paid during the third quarter. Subsequent to the quarter, the Company paid the remaining $100 million . The 2017 Motorola Solutions Credit Agreement includes a $500 million letter of credit sub-limit with $450 million of fronting commitments. Borrowings under the facility bear interest at the prime rate plus the applicable margin, or at a spread above the London Interbank Offered Rate ("LIBOR"), at the Company's option. The weighted average borrowing rate on outstanding amounts for the three and nine months ended September 29, 2018 was 3.58% . An annual facility fee is payable on the undrawn amount of the credit line. The interest rate and facility fee are subject to adjustment if the Company's credit rating changes. The Company must comply with certain customary covenants including a maximum leverage ratio, as defined in the 2017 Motorola Solutions Credit Agreement. The Company was in compliance with its financial covenants as of September 29, 2018 . Also in conjunction with the Avigilon acquisition in the first quarter of 2018, the Company entered into a term loan for $400 million with a maturity date of March 26, 2021 (the “Term Loan”). Interest on the Term Loan is variable, indexed to LIBOR, and paid monthly. The weighted average borrowing rates for amounts outstanding during the three and nine months ended September 29, 2018 were 3.33% and 3.43% , respectively. No additional borrowings are permitted and amounts borrowed and repaid or prepaid may not be re-borrowed. In February of 2018, the Company issued $500 million of 4.60% Senior notes due 2028. The Company recognized net proceeds of $497 million after debt issuance costs and debt discounts. These proceeds were then used to make a $500 million contribution to the Company's U.S. pension plan. On August 25, 2015, the Company entered into an agreement with Silver Lake Partners to issue $1.0 billion of 2.00% Senior Convertible Notes which mature in September 2020. The notes became fully convertible as of August 25, 2017. The notes are convertible based on a conversion rate of 14.8252 , as may be adjusted for dividends declared, per $1,000 principal amount (which is currently equal to a conversion price of $67.45 per share). The exercise price adjusts automatically for dividends.

As of September 29, 2018, the Company paid $169 million of cash to Silver Lake Partners and recorded a gain of $6 million from the extinguishment of the convertible debt. The principal amount of $200 million was reclassified to short term debt.

In the event of an additional conversion, the Company intends to settle the principal amount of the Senior Convertible Notes in cash. On September 28, 2018, the Company issued an additional $200 million on the outstanding 4.60% Senior notes due 2028 bringing the outstanding total to $700 million .

Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes At the end of each interim reporting period, the Company makes an estimate of its annual effective income tax rate. Tax expense in interim periods is calculated at the estimated annual effective tax rate plus or minus the tax effects of items of income and expense that are discrete to the period. The estimate used in providing for income taxes on a year-to-date basis may change in subsequent interim periods. The following table provides details of income taxes: Three Months Ended Nine Months Ended September 29, September 30, September 29, September 30, Net earnings before income taxes $ 270 $ 286 $ 637 $ 610 Income tax expense 22 73 91 188 Effective tax rate 8 % 26 % 14 % 31 % The Company recorded $22 million of net tax expense during the three months ended September 29, 2018 , resulting in an effective tax rate of 8% , compared to $73 million of net tax expense during the three months ended September 30, 2017 , resulting in an effective tax rate of 26% . The effective tax rate for the three months ended September 29, 2018 of 8% is lower than the effective tax rate for the three months ended September 30, 2017 of 26% , primarily due to the following items: (i) corporate income tax rate decrease from 35% to 21% as a result of the U.S. Tax Cuts and Jobs Act (the “Tax Act”) enacted December 22, 2017; (ii) a tax benefit due to the recognition of excess tax benefits on share-based compensation; and (iii) a tax benefit related to the recording of U.S. federal return-to-provision adjustments. The effective tax rate in the third quarter of 2018 was lower than the U.S. statutory tax rate of 21% primarily driven by a tax benefit due to the recognition of tax benefits on share-based compensation and a tax benefit related to the recording of U.S. federal return-to-provision adjustments. The effective tax rate in the third quarter of 2017 was lower than the U.S. statutory tax rate of 35% primarily driven by a tax benefit due to the recognition of a U.S. capital loss. The Company recorded $91 million of net tax expense during the nine months ended September 29, 2018 , resulting in an effective tax rate of 14% , compared to $188 million of net tax expense during the nine months ended September 30, 2017 , resulting in an effective tax rate of 31% . The effective tax rate for the nine months ended September 29, 2018 of 14% is lower than the effective tax rate for the nine months ended September 30, 2017 of 31% , primarily due to the following items: (i) corporate income tax rate decrease from 35% to 21% as a result of the Tax Act; (ii) a tax benefit due to the recognition of excess tax benefits on share-based compensation; and (iii) a tax benefit related to the recording of U.S. federal return-to-provision adjustments. The effective tax rate for nine months ended September 29, 2018 was lower than the U.S. statutory tax rate of 21% primarily due to: (i) the recognition of excess tax benefits on share-based compensation, (ii) a tax benefit due to a favorable settlement of a state audit, and (iii) a tax benefit related to the recording of U.S. federal return-to-provision adjustments. The effective tax rate for the nine months ended September 30, 2017 was lower than the U.S. statutory tax rate of 35% primarily due to a tax benefit due to the recognition of a U.S. capital loss. Under the guidance in the U.S. Securities and Exchange Commission's Staff Accounting Bulletin No. 118 ("SAB 118"), the Company recorded provisional amounts for the impact of the Tax Act as of December 31, 2017, representing $874 million of incremental tax expense.

Fair Value Disclosures [Abstract]
Fair Value Measurements	Fair Value Measurements The Company holds or has held certain fixed income securities, equity securities and derivatives, which are recognized and disclosed at fair value in the financial statements 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 in an orderly transaction between market participants as of the measurement date. Fair value is measured using the fair value hierarchy and related valuation methodologies as defined in the authoritative literature. This guidance specifies a hierarchy of valuation techniques based on whether the inputs to each measurement are observable or unobservable. Observable inputs reflect market data obtained from independent sources, while unobservable inputs reflect the Company's assumptions about current market conditions. The fair value hierarchy and related valuation methodologies are as follows: Level 1—Quoted prices for identical instruments in active markets. Level 2—Quoted prices for similar instruments in active markets, quoted prices for identical or similar instruments in markets that are not active and model-derived valuations, in which all significant inputs are observable in active markets. Level 3—Valuations derived from valuation techniques, in which one or more significant inputs are unobservable. The fair values of the Company’s financial assets and liabilities by level in the fair value hierarchy as of September 29, 2018 and December 31, 2017 were as follows: September 29, 2018 Level 1 Level 2 Total Assets: Foreign exchange derivative contracts $ — $ 6 $ 6 Corporate bonds 2 — 2 Common stock — 17 17 Liabilities: Foreign exchange derivative contracts $ — $ 1 $ 1 December 31, 2017 Level 1 Level 2 Total Assets: Foreign exchange derivative contracts $ — $ 5 $ 5 Available-for-sale securities: Corporate bonds — 2 2 Common stock 13 — 13 Liabilities: Foreign exchange derivative contracts $ — $ 5 $ 5 The Company had no Level 3 holdings as of September 29, 2018 or December 31, 2017 . At September 29, 2018 and December 31, 2017 , the Company had $284 million and $633 million , respectively, of investments in money market prime and government funds (Level 1) classified as Cash and cash equivalents in its condensed consolidated balance sheets. The money market funds had quoted market prices that are equivalent to par. Using quoted market prices and market interest rates, the Company determined that the fair value of long-term debt at September 29, 2018 and December 31, 2017 was $5.5 billion and $4.6 billion (Level 2), respectively. All other financial instruments are carried at cost, which is not materially different from the instruments’ fair values.

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Commitments and Contingencies Legal Matters The Company is a defendant in various lawsuits, claims, and actions, which arise in the normal course of business. In the opinion of management, the ultimate disposition of these matters will not have a material adverse effect on the Company's condensed consolidated financial position, liquidity, or results of operations. However, an unfavorable resolution could have a material adverse effect on the Company's consolidated financial position, liquidity, or results of operations in the periods in which the matters are ultimately resolved, or in the periods in which more information is obtained that changes management's opinion of the ultimate disposition. Other Indemnifications The Company is a party to a variety of agreements pursuant to which it is obligated to indemnify the other party with respect to certain matters. In indemnification cases, payment by the Company is conditioned on the other party making a claim pursuant to the procedures specified in the particular contract, which procedures typically allow the Company to challenge the other party's claims. In some instances, the Company may have recourse against third parties for certain payments made by the Company. Some of these obligations arise as a result of divestitures of the Company's assets or businesses and require the Company to indemnify the other party against losses arising from breaches of representations and warranties and covenants and, in some cases, the settlement of pending obligations. The Company's obligations under divestiture agreements for indemnification based on breaches of representations and warranties are generally limited in terms of duration and to amounts not in excess of a percentage of the contract value. The Company had no accruals for any such obligations at September 29, 2018 . In addition, the Company may provide indemnifications for losses that result from the breach of general warranties contained in certain commercial and intellectual property agreements. Historically, the Company has not made significant payments under these agreements.

Intangible Assets and Goodwill	Intangible Assets and Goodwill The Company accounts for acquisitions using purchase accounting with the results of operations for each acquiree included in the Company's condensed consolidated financial statements for the period subsequent to the date of acquisition. Avigilon Corporation On March 28, 2018, the Company completed the acquisition of Avigilon Corporation, a provider of advanced end-to-end security and surveillance solutions including video analytics, network video management hardware and software, surveillance cameras and access control solutions. The purchase price of $974 million , consisted of cash payments of $980 million for outstanding common stock, restricted stock units and employee held stock options, net of cash acquired of $107 million , debt assumed of $75 million and transaction costs of $26 million . Prior to the end of the first quarter, $35 million of the assumed debt was repaid with the remaining $40 million repaid during the second quarter of 2018. The acquisition of Avigilon has been accounted for at fair value as of the acquisition date, based on the fair value of the total consideration transferred which has been attributed to all identifiable assets acquired and liabilities assumed and measured at fair value. The purchase accounting is not yet complete and as such the final allocation between deferred income tax accounts and goodwill may be subject to change. The following table summarizes fair values of assets acquired and liabilities assumed as of the March 28, 2018 acquisition date: Accounts receivable, net $ 67 Inventory 93 Other current assets 18 Property, plant and equipment, net 33 Deferred income taxes 4 Accounts payable (21 ) Accrued liabilities (28 ) Deferred income tax liabilities (134 ) Goodwill 444 Intangible assets 498 Total consideration $ 974 Acquired intangible assets consist of $110 million of customer relationships, $380 million of developed technology and $8 million of trade names and will have useful lives of two to 20 years . The fair values of all intangible assets were estimated using the income approach. Customer relationships and developed technology were valued under the excess earnings method which assumes that the value of an intangible asset is equal to the present value of the incremental after-tax cash flows attributable specifically to the intangible asset. Trade names were valued under the relief from royalty method, which assumes value to the extent that the acquired company is relieved of the obligation to pay royalties for the benefits received from them. Goodwill is calculated as the excess of the consideration transferred over the net assets recognized and represents the future economic benefits arising from the other assets acquired that could not be individually identified and separately recognized. Goodwill is no t deductible for tax purposes. The pro forma effect of this acquisition is not significant. Other Acquisitions On April 9, 2018, the Company completed the acquisition of a provider of two-way radio communications for a gross purchase price of $11 million , recognizing $7 million of identifiable intangible assets, which will be amortized over a period of seven years .

The identifiable intangible assets will be amortized over a period of 10 to 20 years . The purchase accounting is not yet complete and as such the final allocation between deferred income tax accounts and goodwill may be subject to change.

The estimated identifiable intangible assets were classified as $56 million of customer-related intangibles and $5 million of other intangibles and will be amortized over a period of seven years . The pro forma effects of these acquisitions are not significant. Intangible Assets Amortized intangible assets were comprised of the following: September 29, 2018 December 31, 2017 Gross Carrying Amount Accumulated Amortization Gross Carrying Amount Accumulated Amortization Completed technology $ 559 $ 81 $ 148 $ 55 Patents 2 2 2 2 Customer-related 1,115 344 977 242 Other intangibles 75 27 56 23 $ 1,751 $ 454 $ 1,183 $ 322 Amortization expense on intangible assets was $46 million for the three months ended September 29, 2018 and $140 million for the nine months ended September 29, 2018 . Amortization expense on intangible assets was $39 million for the three months ended September 30, 2017 and $111 million for the nine months ended September 30, 2017 . As of September 29, 2018 , annual amortization expense is estimated to be $189 million in 2018 , $193 million in 2019 , $191 million in 2020 , $187 million in 2021 , $184 million in 2022 , and $84 million in 2023 . Amortized intangible assets, excluding goodwill, were comprised of the following by segment: September 29, 2018 December 31, 2017 Gross Accumulated Gross Accumulated Products and Systems Integration $ 510 $ 29 $ 12 $ 8 Services and Software 1,241 425 1,171 314 $ 1,751 $ 454 $ 1,183 $ 322 Goodwill The following table displays a rollforward of the carrying amount of goodwill by segment from January 1, 2018 to September 29, 2018 : Products and Systems Integration Services and Software Total Balance as of January 1, 2018 $ 362 $ 576 $ 938 Goodwill acquired 359 231 590 Purchase accounting adjustments 10 7 17 Foreign currency — (4 ) (4 ) Balance as of September 29, 2018 $ 731 $ 810 $ 1,541 During the second quarter of 2018, the Company modified its internal reporting structure to better align the way financial information is reported to and analyzed by executive leadership, in part, as a result of recent acquisitions contributing to the growth within the newly aligned Services and Software segment. Previously, the Company had two reporting segments: Products and Services. The changes in reporting structure consist of Systems Integration-related revenue and costs moving from the old Services segment into the newly presented Products and Systems Integration segment and Software related revenue and costs moving from the old Products segment into the newly presented Services and Software segment.

Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation	The condensed consolidated financial statements as of September 29, 2018 and for the three and nine months ended September 29, 2018 and September 30, 2017 include, in the opinion of management, all adjustments (consisting of normal recurring adjustments and reclassifications) necessary to present fairly the condensed consolidated balance sheets, statements of operations, statements of comprehensive income, statement of stockholders' equity, and statements of cash flows of Motorola Solutions, Inc. (“Motorola Solutions” or the “Company”) for all periods presented. Certain information and footnote disclosures normally included in financial statements prepared in accordance with U.S. generally accepted accounting principles (“U.S. GAAP”) have been condensed or omitted. These condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and notes thereto included in the Company’s Form 10-K for the year ended December 31, 2017 . The results of operations for the three and nine months ended September 29, 2018 are not necessarily indicative of the operating results to be expected for the full year. The preparation of financial statements in conformity with U.S. GAAP requires management to make certain estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting periods. Actual results could differ from those estimates.
Recent Accounting Pronouncements	In February 2016, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") No. 2016-02, "Leases," which amends existing guidance to require lessees to recognize assets and liabilities on the balance sheet for the rights and obligations created by long-term leases and to disclose additional quantitative and qualitative information about leasing arrangements. The ASU is effective for the Company on January 1, 2019 and interim periods within that reporting period, with early adoption permitted. In July 2018, the FASB issued ASU 2018-11 that amended the ASU to include an additional (and optional) transition relief. The additional transition relief provides entities the option to adopt the ASU by applying the new ASU at the adoption date and recognizing a cumulative-effect adjustment to the opening balance of retained earnings in the period of adoption without restatement of comparative periods. The new ASU must be adopted utilizing the modified retrospective method as of the earliest comparative period presented if the optional adoption method is not selected. The Company will adopt the ASU on January 1, 2019, utilizing the modified retrospective method as of the adoption date. The Company is continuing to assess the impact of the ASU on its condensed consolidated financial statements, including the package of available practical expedients, required disclosures, and changes to internal controls. Based on the preliminary work completed, the Company expects a material impact to its condensed consolidated balance sheet through the recording of right-of-use assets and lease obligations that are not required to be recorded within the condensed consolidated balance sheet under current accounting standards. In June 2016, the FASB issued ASU No. 2016-13, “Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments,” which requires entities to estimate and recognize current expected credit losses rather than delay recognition of credit losses until the loss is probable of occurring. The ASU is effective for the Company on January 1, 2020, and interim periods within that reporting period with early option permitted. The Company is currently evaluating the impact of the ASU on its consolidated financial statements and disclosures. In August 2017, the FASB issued ASU No. 2017-12, "Derivatives and Hedging (Topic 815): Targeted Improvements to Accounting for Hedging Activities," which is intended to simplify the application of hedge accounting and better portray the economic results of risk management strategies in the consolidated financial statements. The ASU expands and refines hedge accounting for both financial and non-financial risk components, aligns the recognition and presentation of the effects of hedging instruments and hedge items in the financial statements, and includes certain targeted improvements to ease the application of current guidance related to the assessment of hedge effectiveness. The ASU is effective for the Company on January 1, 2019 with adoption permitted immediately in any interim or annual period (including the current period). The guidance related to cash flow and net investment hedges existing at the date of adoption should be applied using the modified retrospective method by means of a cumulative-effect adjustment to the balance sheet as of the beginning of the fiscal year of adoption. The guidance related to presentation and disclosure should be applied prospectively. The Company is currently assessing the impact of this ASU, including transition elections and required elections, on its consolidated financial statements and disclosures. In August 2018, the FASB issued ASU No. 2018-14, “Compensation - Retirement Benefits - Defined Benefit Plans - General (Subtopic 715-20) - Changes to the Disclosure Requirements for Defined Benefit Plans,” which modifies the disclosure requirements for the defined benefit pension plans and other postretirement plans. The ASU is effective for the Company on January 1, 2020 with early adoption permitted. The ASU requires a retrospective adoption method. The Company does not believe the ASU will have a material impact on its financial statement disclosures. Recently Adopted Accounting Pronouncements The Company adopted ASU No. 2016-16, “Accounting for Income Taxes: Intra-Entity Asset Transfers of Assets Other than Inventory” on January 1, 2018 using the modified retrospective method of adoption. The Company recognized $31 million related to the cumulative effect of applying the ASU as an adjustment to its opening retained earnings balance. The comparative information has not been restated and continues to be reported under accounting standards in effect in those periods. This ASU eliminates the prior application of deferring the income tax effect of intra-entity asset transfers, other than inventory, until the transferred asset is sold to a third party or otherwise recovered through use. Under the ASU, the Company will recognize tax expense when intra-entity transfers of assets other than inventory occur. The Company adopted ASU No. 2017-07, “Compensation - Retirement Benefits (Topic 715) - Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost” on January 1, 2018 using the retrospective method of adoption. The amendments in the ASU require that an employer disaggregate the service cost component from the other components of net periodic cost (benefit) and report that component in the same line item as other compensation costs arising from services rendered by employees during the period. The other components of net periodic cost (benefit) are required to be presented in the statement of operations separately from the service cost component and outside of operating earnings. The Company has restated its comparative period results to reflect the application of the presentation guidance of the ASU. As a result of the ASU, the presentation of net periodic cost (benefit) has been updated to classify all components of the Company’s net periodic benefit, with the exception of the service cost component, within Other in Other income (expense) on the statement of operations. The Company reclassified $18 million and $10 million in the three months ended September 29, 2018 and September 30, 2017 , respectively, and $58 million and $10 million in the nine months ended September 29, 2018 and September 30, 2017 , respectively. The Company adopted ASU No. 2014-09, "Revenue from Contracts with Customers," and all the related amendments (collectively “ASC 606”) on January 1, 2018 using the modified retrospective method. The Company recognized the cumulative effect of initially applying the new revenue standard as an adjustment to its opening retained earnings. The comparative information has not been restated and continues to be reported under the accounting standards in effect in those periods. The Company has retained much of the same accounting treatment used to recognize revenue under ASC 606 as under accounting standards in effect in prior periods. Revenue on a significant portion of its System and Integration services contracts continues to be recognized under percentage of completion accounting, applying a cost-to-cost method. Services contracts continue to be recognized ratably over relevant contract terms as the Company stands ready to perform. Finally, revenue on equipment sales continues to be recognized based on delivery terms as aligned with the transfer of control. Under the new standard, the Company identified distinct promises to transfer goods and services within its contracts. For system contracts that are recognized under percentage of completion accounting, the Company has considered the factors used to determine whether promises made in the contract are distinct and determined that devices and accessories represent distinct goods. Accordingly, adoption of the new standard impacts the Company's system contracts, with the result being revenue recognized earlier as control of devices and accessories transfers to the customer at a point in time rather than over time. For the remaining promised goods and services within the Company's system contracts, it continues to recognize revenue on these contracts using a cost-to-cost method based on the continuous transfer of control to the customer over time. Under the new standard, revenue recognition for software sales is accelerated based on when control of software licenses and related support services are transferred to the customer. Amounts deferred under previous software accounting rules due to lack of vendor-specific objective evidence have been recognized as an adjustment through opening retained earnings. Historically, the Company presented transactions that involved a third-party sales representative on a net basis. After considering the control concept and the remaining three indicators of gross presentation under the new standard, the Company has determined that it is the principal in contracts that involve a third-party sales representative. Thus, under the new standard, the Company presents associated revenues on a gross basis, with the affect being an equal increase to selling, general and administrative expenses for its cost of third-party commissions. Under prior accounting standards, the Company expensed sales commissions and other costs to obtain a contract as incurred. However, under the new standard, the Company capitalizes sales commissions and certain other costs as incremental costs to obtain a contract. Such costs are classified as non-current contract cost assets within Other assets and amortized over a period that approximates the timing of revenue recognition on the underlying contracts. The new standard clarified the definition of a receivable and requires the Company to present its net position in a contract with a customer on the balance sheet. The position is presented as either a receivable, contract asset, or a contract liability. Under the new definition, accounts receivable are unconditional rights to consideration from a customer. Contract assets represent rights to consideration from a customer in exchange for transferred goods and services that are conditional on events other than the passage of time. Contract liabilities represent obligations to transfer goods and services for which the Company has received, or is due, consideration from a customer. The Company reclassified its customer positions to align with the new definitions and presentation guidance. Accordingly, Unbilled accounts receivable and Costs and earnings in excess of billings have been reclassified from Accounts receivable and Other current assets, respectively, and are presented as Contract assets. Accounts receivable which are not due from customers have been reclassified into Other current assets. Deferred revenue, Billings in excess of costs and earnings, and Customer downpayments have been reclassified from Accrued liabilities and are presented as Contract liabilities. Non-current deferred revenue has been reclassified from Deferred revenue to Non-current contract liabilities within Other liabilities.
Revenue from Contracts with Customers	Payment terms on system contracts are typically tied to implementation milestones associated with progress on contracts, while revenue recognition is over time based on a cost-to-cost method of measuring performance. The Company may recognize a contract asset or contract liability, depending on whether revenue has been recognized in excess of billings or billings in excess of revenue. Services contracts are typically billed in advance, generating Contract liabilities until the Company has performed the services. The Company does not record a financing component to contracts when it expects, at contract inception, that the period between the transfer of a promised good or service and related payment terms are less than a year. Significant Judgments The Company enters into arrangements which consist of multiple promises to our customers. The Company evaluates whether the promised goods and services are distinct or a series of distinct goods or services. Where contracts contain multiple performance obligations, the Company generally allocates the total estimated consideration to each performance obligation based on applying an estimated selling price (“ESP”) as our best estimate of standalone selling price. The Company determines ESP by: (i) collecting all reasonably available data points including sales, cost and margin analysis of the product or services, and other inputs based on its normal pricing and discounting practices, (ii) making any reasonably required adjustments to the data based on market and Company-specific factors, and (iii) stratifying the data points, when appropriate, based on major product or service, type of customer, geographic market, and sales volume. The Company accounts for certain system contracts on an over time basis, electing an input method of estimated costs as a measure of performance completed. The selection of the measurement of progress using estimated costs was based on a thorough consideration of alternatives of various output and input measures, including contract milestones and labor hours. However, the Company has determined that other input and output measures are not an appropriate measure of progress as they do not accurately align with the transfer of control on its customized product solutions. The selection of costs incurred as a measure of progress aligns the transfer of control to the overall production of the customized system . For system contracts accounted for over time using estimated costs as a measure of performance completed, the Company relies on estimates around the total estimated costs to complete the contract (“Estimated Costs at Completion”). Total Estimated Costs at Completion include direct labor, material and subcontracting costs. Due to the nature of the efforts required to be performed to meet the underlying performance obligation, determining Estimated Costs at Completion may be complex and subject to many variables. We have a standard and disciplined quarterly process in which management reviews the progress and performance of open contracts in order to determine the best estimate of Estimated Costs at Completion. As part of this process, management reviews information including, but not limited to, any outstanding key contract matters, progress towards completion, the project schedule, identified risks and opportunities, and the related changes in estimates of costs. The risks and opportunities include management’s judgment about the ability and cost to achieve the project schedule, technical requirements, and other contract requirements. Management must make assumptions and estimates regarding labor productivity and availability, the complexity of work to be performed, the availability and cost of materials, and performance by subcontractors, among other variables. Based on this analysis, any quarterly adjustment to net sales, cost of sales, and the related impact to operating income are recorded as necessary in the period they become known. When estimates of total costs to be incurred on a contract exceed estimates of total revenue to be earned, a provision for the entire loss on the contract is recorded in the period in which the loss is determined. In accordance with ASC 606, the Company recognizes revenue to reflect the transfer of control of promised goods or services to customers in an amount that reflects the consideration to which the Company expects to be entitled in exchange for goods or services. The Company records revenue following the five steps below: 1. Identify the contract with customers: A contract is an agreement between two or more parties that creates enforceable rights and obligations and specifies that enforceability is a matter of law. Contracts shall be accounted for when: (i) the parties to the contract have approved the contract (in writing, orally, or in accordance with other customary business practices) and are committed to perform their respective obligations, (ii) the Company can identify each party’s rights regarding the goods or services to be transferred, (iii) the Company can identify the payment terms for the goods or services to be transferred, (iv) the contract has commercial substance (that is, the risk, timing, or amount of the Company’s future cash flow is expected to change as a result of the contract), and (v) it is probable that the Company will collect substantially all of the consideration to which it will be entitled in exchange for the goods or services that will be transferred to the customer. It is the Company’s customary business practice to obtain a signed legal document as evidence of an arrangement. 2. Identify performance obligations in contracts: The goods or services promised in a contract must be evaluated at inception to identify as a performance obligation each promise to transfer to the customer either: (i) a distinct good or service, or (ii) a series of distinct goods or services that are substantially the same and that have the same pattern of transfer to the customer. 3. Determine the transaction price: The transaction price is the amount of consideration to which the Company expects to be entitled in exchange for transferring goods or services to a customer, excluding amounts collected on behalf of third parties. In determining the transaction price, the Company considers the following components: (i) variable consideration, (ii) significant financing, (iii) noncash consideration, and (iv) consideration payable to a customer. 4. Allocate the transaction price: For a contract that has more than one distinct performance obligation, the Company must allocate the transaction price to each distinct performance obligation in an amount that depicts the amount of consideration to which the Company expects to be entitled in exchange for satisfying that specific performance obligation. 5. Recognize revenue when or as the entity satisfies a performance obligation: The Company recognizes revenue when, or as, it satisfies a performance obligation by transferring control of a promised good or service to a customer.
