Accounting Policies [Abstract]
The Company	THE COMPANY Description of Business National CineMedia, Inc. (“NCM, Inc.”) was incorporated in Delaware as a holding company with the sole purpose of becoming a member and sole manager of National CineMedia, LLC (“NCM LLC”), a limited liability company owned by NCM, Inc., American Multi-Cinema, Inc. and AMC ShowPlace Theatres, Inc., wholly owned subsidiaries of AMC Entertainment, Inc. (“AMC”), Regal Cinemas, Inc. and Regal CineMedia Holdings, LLC, wholly owned subsidiaries of Cineworld Group plc and Regal Entertainment Group (“Regal”) and Cinemark Media, Inc. and Cinemark USA, Inc., wholly owned subsidiaries of Cinemark Holdings, Inc. (“Cinemark”). The terms “NCM”, “the Company” or “we” shall, unless the context otherwise requires, be deemed to include the consolidated entity. AMC, Regal, Cinemark and their affiliates are referred to in this document as “founding members”. NCM LLC operates the largest digital in-theater network in North America, allowing NCM LLC to sell advertising under long-term exhibitor services agreements (“ESAs”) with the founding members (approximately 19 years remaining as of June 28, 2018 ) and certain third-party theater circuits, referred to in this document as “network affiliates” under long-term network affiliate agreements, which have terms from one to twenty years. As of June 28, 2018 , NCM LLC had 157,576,354 common membership units outstanding, of which 76,915,532 ( 48.8% ) were owned by NCM, Inc., 30,403,438 ( 19.3% ) were owned by Regal, 28,779,904 ( 18.3% ) were owned by Cinemark and 21,477,480 ( 13.6% ) were owned by AMC. The membership units held by the founding members are exchangeable into NCM, Inc. common stock on a one -for-one basis. Basis of Presentation The Company has prepared the unaudited Condensed Consolidated Financial Statements and related notes of NCM, Inc. in accordance with accounting principles generally accepted in the United States of America (“GAAP”) for interim financial information and the rules and regulations of the Securities and Exchange Commission (“SEC”). Accordingly, certain information and footnote disclosures typically included in an annual report have been condensed or omitted for this quarterly report. The balance sheet as of December 28, 2017 is derived from the audited financial statements of NCM, Inc. Therefore, the unaudited Condensed Consolidated Financial Statements should be read in conjunction with the audited Consolidated Financial Statements and notes thereto included in the Company’s annual report on Form 10-K filed for the fiscal year ended December 28, 2017 . In the opinion of management, all adjustments necessary to present fairly in all material respects the financial position, results of operations and cash flows for all periods presented have been made. The Company’s business is seasonal and for this and other reasons operating results for interim periods may not be indicative of the Company’s full year results or future performance. As a result of the various related party agreements discussed in Note 5— Related Party Transactions , the operating results as presented are not necessarily indicative of the results that might have occurred if all agreements were with non-related third parties. The Company manages its business under one reportable segment of advertising. Estimates —The preparation of the financial statements in conformity with GAAP requires management to make 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 period. Significant estimates include those related to the reserve for uncollectible accounts receivable, share-based compensation and income taxes. Actual results could differ from those estimates. Significant Accounting Policies The Company’s annual financial statements included in its Form 10-K filed for the fiscal year ended December 28, 2017 contain a complete discussion of the Company’s significant accounting policies. Following is additional information related to the Company’s accounting policies. Revenue Recognition —The Company derives revenue principally from the advertising business, which includes on-screen and lobby network (LEN) advertising and lobby promotions and advertising on entertainment websites and mobile applications owned by NCM LLC and other companies. Revenue is recognized over time as the customer receives the benefits provided by NCM LLC’s advertising services and the Company has the right to payment for performance to date. The Company considers the terms of each arrangement to determine the appropriate accounting treatment as more fully discussed in Note 2 - Revenue from Contracts with Customers . Concentration of Credit Risk and Significant Customers —Bad debts are provided for using the allowance for doubtful accounts method based on historical experience and management’s evaluation of outstanding receivables at the end of the period. Receivables are written off when management determines amounts are uncollectible. Trade accounts receivable are uncollateralized and represent a large number of geographically dispersed debtors. The collectability risk with respect to national and regional advertising is reduced by transacting with founding members or large, national advertising agencies that have strong reputations in the advertising industry and clients with stable financial positions. The Company has smaller contracts with thousands of local clients that are not individually significant. As of June 28, 2018 and December 28, 2017 , there were no advertising agency groups or individual customers through which the Company sources national advertising revenue representing more than 10% of the Company’s outstanding gross receivable balance. During the three and six months ended June 28, 2018 and June 29, 2017 , the Company had no customers that accounted for more than 10% of revenue. Share-Based Compensation —The Company has issued stock options and restricted stock to certain employees and restricted stock units to its independent directors. The Company has not granted stock options since 2012. In 2017 and 2018, the restricted stock grants for Company officers vest upon the achievement of Company performance measures and/or service conditions, while non-officer grants vest only upon the achievement of service conditions. Compensation expense of restricted stock that vests upon the achievement of Company performance measures is based on management’s financial projections and the probability of achieving the projections, which require considerable judgment. A cumulative adjustment is recorded to share-based compensation expense in periods that management changes its estimate of the number of shares of restricted stock expected to vest. Ultimately, the Company adjusts the expense recognized to reflect the actual vested shares following the resolution of the performance conditions. Dividends are accrued when declared on unvested restricted stock that is expected to vest and are only paid with respect to shares that actually vest. During the three and six months ended June 28, 2018 and June 29, 2017 , 19,357 , 29,759 , 975,596 and 1,008,118 shares of restricted stock and restricted stock units vested, respectively. During the three and six months ended June 28, 2018 , and June 29, 2017 , 0 , 0 , 0 , and 58,450 stock options were exercised at a weighted average exercise price of $0.00 , $0.00 , $ 0.00 and $ 11.04 per share. Consolidation —NCM, Inc. consolidates the accounts of NCM LLC under the provisions of ASC 810, Consolidation (“ASC 810”). The following table presents the changes in NCM, Inc.’s equity resulting from net income attributable to NCM, Inc. and transfers to or from noncontrolling interests (in millions): Six Months Ended June 28, June 29, Net income attributable to NCM, Inc. $ 2.3 $ 3.9 NCM LLC equity issued for purchase of intangible asset 7.7 78.8 Income tax and other impacts of subsidiary ownership changes (3.1 ) (46.0 ) Change from net loss attributable to NCM, Inc. and transfers from noncontrolling interests $ 6.9 $ 36.7 Recently Adopted Accounting Pronouncements During the first quarter of 2018, the Company adopted Accounting Standards Update 2014-9, Revenue from Contracts with Customers (Topic 606) (“ASU 2014-9”) using the modified retrospective transition method. The Company identified the same performance obligations under ASU 2014-9 as compared with deliverables and separate units of account previously identified. ASU 2014-9 impacted the accounting for barter transactions where the Company exchanges advertising time for products and services used principally for selling and marketing activities. The Company historically recognized revenue for these transactions at the estimated fair value of the advertising exchanged based on the fair value received for similar advertising from cash paying customers. In accordance with the new guidance, the Company will recognize revenue for these transactions based upon the fair value of the products and services received, rather than the value of the advertising provided. The modified retrospective transition method allows entities to apply the new revenue standard prospectively and record a cumulative-effect adjustment to the opening balance of retained earnings in the period the new revenue standard is first applied. Upon the adoption of ASU 2014-9 on December 29, 2017, the Company recorded a $0.2 million cumulative-effect adjustment related to the change in accounting for barter transactions on contracts that are not completed as of December 29, 2017 in the unaudited Consolidated Balance Sheet. The Company’s adoption of ASU 2014-9 did not have a material impact on the unaudited Condensed Consolidated Financial Statements. The Company has incorporated additional disclosures in Note 2 – Revenue from Contracts with Customers to the unaudited Condensed Consolidated Financial Statements to comply with ASU 2014-9. During the first quarter of 2018, the Company adopted Accounting Standards Update 2016-1, Recognition and Measurement of Financial Assets and Financial Liabilities (“ASU 2016-1”), which requires equity investments that are not accounted for under the equity method of accounting to be measured at fair value with changes recognized in earnings (rather than reported through other comprehensive income) and updates certain presentation and disclosure requirements. In February 2018, the FASB issued Accounting Standards Update 2018-3, Technical Corrections and Improvements to Financial Instruments – Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities (“ASU 2018-3”). These amendments clarify the guidance on certain topics referred to in ASU 2016-1. The Company has incorporated changes to the methodology utilized to value the Company’s investments and changes to disclosures in its notes to the unaudited Condensed Consolidated Financial Statements to comply with ASU 2016-1. During the first quarter of 2018, the Company adopted Accounting Standards Update 2016-15, Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments (“ASU 2016-15”) on a retrospective basis. ASU 2016-15 provides guidance on certain cash receipts and cash payments presented and classified in the statement of cash flows. The adoption of ASU 2016-15 did not have a material impact on the unaudited Condensed Consolidated Financial Statements or notes thereto. During the first quarter of 2018, the Company adopted Accounting Standards Update 2016-18, Statement of Cash Flows (Topic 230): Restricted Cash (“ASU 2016-18”) on a retrospective basis. ASU 2016-18 requires that the reconciliation of the beginning-of-period and end-of-period amounts shown in the statement of cash flows include restricted cash and restricted cash equivalents. The Company has adjusted the Condensed Consolidated Statement of Cash Flow for the six months ended June 29, 2017 to include the restricted cash balance within the aforementioned captions. The adoption of ASU 2016-18 had no other impact on the unaudited Condensed Consolidated Financial Statements or notes thereto. In July 2018, the FASB issued Accounting Standards Update 2018-9, Codification Improvements ("ASU 2018-9”), which makes minor amendments to the codification in order to clarify, correct errors in, eliminate inconsistencies and provide clarifications in current guidance. The ASU amends Subtopics 470-50, Debt-Modifications and Extinguishments and 718-740, Compensation-Stock Compensation-Income Taxes and is effective immediately. The adoption of ASU 2018-9 did not have a material impact on the unaudited Condensed Consolidated Financial Statements or notes thereto. Recently Issued Accounting Pronouncements In February 2016, the FASB issued Accounting Standards Update 2016-2, Leases (Topic 842) (“ASU 2016-2”). ASU 2016-2 establishes a right-of-use (“ROU”) model that requires a lessee to record a ROU asset and a lease liability on the balance sheet for all leases with terms longer than twelve months. Leases will be classified as either finance or operating, with classification affecting the pattern of expense recognition in the income statement. The new standard is effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. A modified retrospective transition approach is required for lessees for capital and operating leases existing at, or entered into after, the beginning of the earliest comparative period presented in the financial statements, with certain practical expedients available. The Company is currently evaluating the impact that adopting this guidance will have on the unaudited Condensed Consolidated Financial Statements or notes thereto and will adopt its provisions effective January 1, 2019. The Company expects to utilize the following practical expedients: (i) not being required to reassess whether any expired or existing contracts are or contain leases; (ii) not being required to reassess the lease classification for any expired or existing leases (that is, all existing leases that were classified as operating leases in accordance with Topic 840 will be classified as operating leases, and all existing leases that were classified as capital leases in accordance with Topic 840 will be classified as finance leases); and (iii) not being required to reassess initial direct costs for any existing leases. The Company is still evaluating the remaining practical expedients. In June 2016, the FASB issued Accounting Standards Update 2016-13, Financial Instruments – Credit Losses (Topic 326), Measurement of Credit Losses on Financial Statements (“ASU 2016-13”), which requires a financial asset (or group of financial assets) measured at amortized cost basis to be presented at the net amount expected to be collected. The allowance for credit losses is a valuation account that is deducted from the amortized cost basis of the financial asset(s) to present the net carrying value at the amount expected to be collected on the financial asset. ASU 2016-13 is effective for fiscal years beginning after December 15, 2019, including interim periods within those fiscal years, with early adoption permitted and is to be adopted on a modified retrospective basis. The Company is currently evaluating the impact that adopting this guidance will have on the unaudited Condensed Consolidated Financial Statements or notes thereto. In March 2018, the FASB issued Accounting Standards Update 2018-4, Investments – Debt Securities (Topic 320) and Regulated Operations (Topic 980): Amendments to SEC Paragraphs Pursuant to SEC Staff Accounting Bulletin No. 117 and SEC Release No. 33-9273 (“ASU 2018-4”), which amends and supersedes variance paragraphs that contain SEC guidance in ASC 320, Investments-Debt Securities and ASC 980, Regulated Operations . The Company is currently evaluating the impact that adopting this guidance will have on the unaudited Condensed Consolidated Financial Statements or notes thereto. In June 2018, the FASB issued Accounting Standards Update 2018-7, Compensation – Stock Compensation (Topic 718): Improvements to Nonemployee Share-Based Payment Accounting (“ASU 2018-7”), which amends Topic 718 to include share-based payment transactions for acquiring goods and services from nonemployees. ASU 2018-7 is effective for fiscal years beginning December 15, 2018, with early adoption permitted. The Company is currently evaluating the impact that adopting this guidance will have on the unaudited Condensed Consolidated Financial Statements or notes thereto. The Company has considered all other recently issued accounting pronouncements and does not believe the adoption of such pronouncements will have a material impact on its unaudited Condensed Consolidated Financial Statements or notes thereto. Change in Accounting Principle and Correction of an Error During the first quarter of 2018, the Company changed its method of accounting for its payable to founding members under the tax receivable agreement (“TRA”), which requires the Company to pay 90% of the expected cash savings to NCM, Inc. from federal, state, and local jurisdictions upon realization of amortization and other deductions specified under the TRA. At inception of the TRA in 2007, the payable was recorded at fair value by discounting the amounts expected to be payable to founding members under the TRA at the Company’s weighted average cost of capital. The Company then remeasured the present value of the payable to founding members under the TRA each subsequent reporting period. As a result of the change in accounting principle, the payable is now stated at the undiscounted amount of all expected future payments under the agreement. The Company believes that the undiscounted presentation is preferable because it is consistent with the predominant accounting method used by other companies with such TRA agreements and is more consistent with the undiscounted approach used for the corresponding deferred tax assets that are subject to the TRA. Accordingly, the Condensed Consolidated Balance Sheets, Condensed Consolidated Statements of Income, Condensed Statements of Equity (Deficit) and Condensed Consolidated Statement of Cash Flows for the respective prior periods have been recast to reflect retrospective application of the change in accounting principle. Since this change in accounting principle dates back to the Company’s initial public offering ("IPO") in 2007, the Company has recorded the cumulative effect for the change in accounting principle to beginning retained earnings as of December 29, 2016. Additionally, subsequent to the issuance of the Company’s Consolidated Financial Statements for the year ended December 29, 2016 , the Company identified and corrected an immaterial non-cash error related to the accounting under ASC 740 for the Company’s payable to founding members under the TRA which was corrected within the Company’s Form 10-K for the period ending December 28, 2017 . As a result of the error, the liability under the TRA (including the historical discount on such payable) and related accounts for the year ended December 29, 2016 were restated from the amount previously reported to reflect the additional amounts that will be payable under the TRA upon settlement of all expected future payments to the founding members. Further, the deferred tax liability recorded at the IPO related to the discounted TRA liability was reversed to reflect all applicable basis differences related to the TRA. The impact of the error on the Condensed Consolidated Statements of Income for the three and six months ended June 29, 2017 is presented within the tables below and the impact of the error on the Condensed Consolidated Statement of Cash Flows and the Condensed Consolidated Statement of Equity for the six months ended June 29, 2017 is stated below. The Condensed Consolidated Financial Statements and corresponding footnotes for the three and six months ended June 29, 2017 have been restated from the amounts previously reported to reflect the correction of this error as shown within the tables below. The following table presents the effect of the change in accounting principle to the December 29, 2016 beginning retained earnings balance and additional paid in capital (deficit) ("APIC") balance (in millions): Beginning retained earnings (distributions in excess of earnings), as of December 29, 2016 – as previously reported $ (248.3 ) Cumulative effect for change in accounting principle $ 117.6 Beginning retained earnings (distributions in excess of earnings), as of December 29, 2016 – as adjusted $ (130.7 ) Beginning additional paid in capital (deficit), as of December 29, 2016 – as previously reported $ (110.5 ) Cumulative effect for change in accounting principle $ (233.1 ) Beginning additional paid in capital (deficit), as of December 29, 2016 – as adjusted $ (343.6 ) The following table presents the effects of the change in accounting principle to the Condensed Consolidated Balance Sheet (in millions): As of December 28, 2017 As Reported Change in Accounting Principle As Adjusted Long-term deferred tax assets, net of valuation allowance of $98.1 $ 161.0 $ 25.0 $ 186.0 TOTAL ASSETS 1,148.1 25.0 1,173.1 Long-term payable to founding members under tax receivable agreement 114.0 98.6 212.6 Total liabilities 1,149.3 98.6 1,247.9 Additional paid in capital (deficit) 13.8 (246.9 ) (233.1 ) Retained earnings (distributions in excess of earnings) (303.5 ) 173.3 (130.2 ) Total equity/(deficit) (1.2 ) (73.6 ) (74.8 ) TOTAL LIABILITIES AND EQUITY/DEFICIT 1,148.1 25.0 1,173.1 The following tables present the effects of the correction of the prior period error and change in accounting principle to the Condensed Consolidated Statement of Income (in millions, except for per share data): Three Months Ended June 29, 2017 As Reported Correction of an Error As Corrected Change in Accounting Principle As Corrected and Adjusted Accretion of interest on the discounted payable to founding members under tax receivable agreement $ 2.9 $ 1.4 $ 4.3 $ (4.3 ) $ — Gain on re-measurement of the payable to founding members under the tax receivable agreement $ — $ (5.5 ) $ (5.5 ) $ 4.9 $ (0.6 ) Total non-operating expenses $ 15.6 $ (4.1 ) $ 11.5 $ 0.6 $ 12.1 INCOME BEFORE INCOME TAXES $ 12.7 $ 4.1 $ 16.8 $ (0.6 ) $ 16.2 Income tax expense $ 1.8 $ 1.1 $ 2.9 $ (1.3 ) $ 1.6 CONSOLIDATED NET INCOME $ 10.9 $ 3.0 $ 13.9 $ 0.7 $ 14.6 NET INCOME ATTRIBUTABLE TO NCM, INC. $ 1.5 $ 3.0 $ 4.5 $ 0.7 $ 5.2 NET INCOME PER NCM, INC.

Revenue from Contract with Customer [Abstract]
Revenue from Contracts with Customers	REVENUE FROM CONTRACTS WITH CUSTOMERS Revenue Recognition The Company derives revenue principally from the sale of advertising to national, regional and local businesses in Noovie , the Company’s cinema advertising and entertainment pre-show. The Company also sells advertising through the Lobby Entertainment Network (“LEN”), a series of strategically-placed screens located in movie theater lobbies, as well as other forms of advertising and promotions in theater lobbies. In addition, the Company sells online and mobile advertising through the Cinema Accelerator digital product. The Company also has a long-term agreement to exhibit the advertising of the founding members’ beverage suppliers. National advertising, including advertising under the beverage concessionaire and PSA agreements, is sold on a cost per thousand (“CPM”) basis. The Company recognizes national advertising over time as impressions (or theater attendees) are delivered. National advertising is also sold to content partners. The content partners provide the Company with original entertainment content segments, typically 90 seconds in length, that are entertaining, informative, or educational in nature in the Noovie pre-show and they make commitments to buy a portion of the Company’s advertising inventory at a specified CPM. The Company recognizes revenue for the content segments ratably over time as the content segments air. Local and regional advertising is sold on a per-screen, per-week basis and to a lesser extent on a CPM basis. The Company recognizes local on-screen advertising revenue over the period in which the advertising airs as dictated by the underlying sales contracts. When sold separately, LEN advertising and lobby promotions are sold based on length and breadth of the promotion. The Company recognizes revenue derived from lobby network and promotions over time when the advertising is displayed in theater lobbies. The Company sells online and mobile advertising on a CPM basis. The Company recognizes revenue from branded entertainment websites and mobile applications over time as the online or mobile impressions are served. Customer contracts often include multiple advertising services to reach the movie goer at multiple points during a theater experience. The Company considers each of these advertising services to represent distinct performance obligations of the contract and allocates a portion of the transaction price to each service based upon the standalone selling price of the service, when available. When standalone selling prices are not available or not applicable given the nature of the customer, the Company allocates the transaction price based upon all information that is reasonably available and maximizes the use of observable inputs. Methods utilized include the adjusted market and expected cost-plus margin approaches. The Company enters into barter transactions that exchange advertising program time for products and services used principally for selling and marketing activities. The Company records barter transactions at the estimated fair value of the products and services received. Revenues for advertising barter transactions are recognized when advertising is provided, and products and services received are charged to expense when used. The Company makes contractual guarantees to deliver a specified number of impressions to view the customers’ advertising. If the contracted number of impressions are not delivered, the Company will run additional advertising to deliver the contracted impressions at a later date. The deferred portion of the revenue associated with undelivered impressions is referred to as a make-good provision. In rare cases, the Company will make a cash refund of the portion of the contract related to the undelivered impressions. Given the limited history of cash settlements of the make-good provision, the Company recognizes revenue on the guaranteed contracts as the impressions are delivered and no reserve for variable consideration is recorded. The Company defers the revenue associated with the make-good until the advertising airs to the theater attendance specified in the advertising contract. The make-good provision is recorded within accrued expenses in the Condensed Consolidated Balance Sheets. As of June 28, 2018 and December 28, 2017 , the Company had a make-good provision of $2.5 million and $5.5 million , respectively. The Company recognizes revenue as the performance obligation for the advertising services is satisfied. Invoices are generated following the processing of each revenue contract and payment is due from the customer within 30 days of the invoice date. Customers select to pay the invoice in full at the start of a contract or through equal monthly installments over the course of the contract. The Company records deferred revenue when cash payments are received, or invoices are issued, in advance of revenue being earned. Deferred revenue is classified as a current liability as it is expected to be earned within the next twelve months. The Company has certain contracts with two -year terms that are noncancelable following a specified date within the contract period. The estimated revenue expected to be recognized in the future related to these contracted performance obligations that are unsatisfied (or partially unsatisfied) as of June 28, 2018 , was $34.5 million , $10.0 million of which is expected to be recognized in 2018 and $24.5 million is expected to be recognized in 2019. Agreements with a duration less than one year are not included within this disclosure as the Company elected to use the practical expedient in ASC 606-10-50-14 for those contracts. In addition, other of the Company’s contracts longer than one year that are cancelable are not included within this disclosure. Disaggregation of Revenue The Company disaggregates revenue based upon the type of customer: national; local and regional; and beverage concessionaire. This method of disaggregation is in alignment with how revenue is reviewed by management and discussed with and historically disclosed to investors. The following table summarizes revenue from contracts with customers for the three and six months ended June 28, 2018 and June 29, 2017 : Three Months Ended Six Months Ended June 28, June 29, June 28, June 29, National advertising revenue $ 78.8 $ 66.0 $ 133.6 $ 110.4 Local and regional advertising revenue 26.3 23.5 43.7 42.6 Founding member advertising revenue from beverage concessionaire agreements 8.6 7.6 16.6 16.0 Total revenue $ 113.7 $ 97.1 $ 193.9 $ 169.0 Deferred Revenue and Unbilled Accounts Receivable The changes in deferred revenue for the six months ended June 28, 2018 were as follows (in millions): Six Months Ended June 28, Balance at beginning of period $ (7.1 ) Performance obligations satisfied 7.1 New contract liabilities (10.2 ) Balance at end of period $ (10.2 ) Unbilled accounts receivable is classified as a current asset as it is expected to be billed within the next twelve months . As of June 28, 2018 and December 28, 2017 , the Company had $10.1 million and $10.6 million in unbilled accounts receivable, respectively. Practical Expedients and Exemptions The Company expenses sales commissions when incurred as the amortization period would have been one year or less. These costs are recorded within sales and marketing expenses in the Condensed Consolidated Statement of Income. The Company does not disclose the value of unsatisfied performance obligations for contracts with an original expected length of one year or less.

Earnings Per Share [Abstract]
Earnings Per Share	EARNINGS PER SHARE Basic earnings per share is computed on the basis of the weighted average number of common shares outstanding. Diluted earnings per share is computed on the basis of the weighted average number of common shares outstanding plus the effect of potentially dilutive common stock options, restricted stock and restricted stock units using the treasury stock method. The components of basic and diluted income per NCM, Inc. share are as follows: Three Months Ended Six Months Ended June 28, June 29, June 28, June 29, Net income attributable to NCM, Inc.

NCM LLC common units do not participate in dividends paid on NCM, Inc.’s common stock. In addition, there were 2,323,154 , 466,706 , 2,493,613 and 299,257 stock options and non-vested (restricted) shares for the three and six months ended June 28, 2018 and June 29, 2017 , respectively, excluded from the calculation as they were antidilutive. The Company’s non-vested (restricted) shares do not meet the definition of a participating security as the dividends will not be paid if the shares do not vest.

Goodwill and Intangible Assets Disclosure [Abstract]
Intangible Assets	INTANGIBLE ASSETS Intangible assets consist of contractual rights to provide the Company’s services within the theaters of the founding members and network affiliates and are stated at cost, net of accumulated amortization. The Company’s intangible assets with its founding members are recorded at fair market value of NCM, Inc.’s publicly traded stock as of the date on which the common membership units were issued. The NCM LLC common membership units are fully convertible into NCM, Inc.’s common stock. In addition, the Company records intangible assets for up-front fees paid to network affiliates upon commencement of a network affiliate agreement. The Company’s intangible assets have a finite useful life and the Company amortizes the assets over the remaining useful life corresponding with the ESAs or the term of the network affiliate agreement. Common Unit Adjustments —In accordance with NCM LLC’s Common Unit Adjustment Agreement with its founding members, on an annual basis NCM LLC determines the amount of common membership units to be issued to or returned by the founding members based on theater additions or dispositions during the previous year. In addition, NCM LLC’s Common Unit Adjustment Agreement requires that a Common Unit Adjustment occur for a specific founding member if its acquisition or disposition of theaters, in a single transaction or cumulatively since the most recent Common Unit Adjustment, results in an attendance increase or decrease in excess of two percent of the annual total attendance at the prior adjustment date. During the first quarter of 2018 , NCM LLC issued 2,821,710 ( 3,736,860 issued, net of 915,150 returned) common membership units to its founding members for the rights to exclusive access to the theater screens and attendees added, net of dispositions by the founding members to NCM LLC’s network during the 2017 fiscal year and NCM LLC recorded a net intangible asset of $15.9 million during the first quarter of 2018 as a result of the Common Unit Adjustment. During the first quarter of 2017, NCM LLC issued 2,351,029 common membership units to its founding members for the rights to exclusive access to the theater screens and attendees added, net of dispositions by the founding members to NCM LLC’s network during the 2016 fiscal year. Also during the first quarter of 2017, NCM, Inc. and NCM LLC entered into a binding Memorandum of Understanding (“MOU”) with AMC to effectuate aspects of a final judgment (the “Final Judgment”) entered into by the Department of Justice (the “DOJ”) in connection with AMC’s acquisition of Carmike Cinemas, Inc. (“Carmike”). Pursuant to the MOU, the Company issued 18,425,423 NCM LLC common membership units to AMC in respect of the annual attendance at such Carmike theaters in accordance with the Common Unit Adjustment Agreement during the first quarter of 2017. AMC’s acquisition of Carmike meets the criteria for a Common Unit Adjustment because it resulted in an extraordinary attendance increase of approximately 9.5% . Further, the Final Judgment required AMC to transfer advertising rights to 17 theaters from NCM LLC to another advertising provider. Pursuant to the MOU, AMC surrendered 4,657,673 NCM LLC common membership units in respect of such theaters. The 4,657,673 NCM LLC common membership units were comprised of (i) 2,850,453 NCM LLC common membership units pursuant to the adjustment for divested theaters in the Common Unit Adjustment Agreement and (ii) an additional 1,807,220 NCM LLC common membership units valued at $25.0 million to compensate for NCM LLC’s lost operating income for these theaters during the 10 -year term of the Final Judgment. To facilitate the theater transfers, during the first quarter of 2017, AMC and Regal entered into an amendment of its ESA with NCM LLC and Cinemark entered into a waiver of certain rights under its ESA. NCM LLC recorded a net intangible asset of $201.8 million during the first quarter of 2017 related to these transactions. Integration Payments and Other Encumbered Theater Payments —If an existing on-screen advertising agreement with an alternative provider is in place with respect to any acquired theaters, the founding members may elect to receive common membership units related to those encumbered theaters in connection with the Common Unit Adjustment. If the founding members make this election, then they are required to make payments on a quarterly basis in arrears in accordance with certain run-out provisions pursuant to the ESAs (“integration payments”). Because the Carmike theaters are subject to an existing on-screen advertising agreement with an alternative provider, AMC will make integration payments to NCM LLC. The integration payments will continue until the earlier of (i) the date the theaters are transferred to NCM LLC’s network or (ii) the expiration of the ESA. Integration payments are calculated based upon the advertising cash flow that the Company would have generated if it had exclusive access to sell advertising in the theaters with pre-existing advertising agreements. The ESA additionally entitles NCM LLC to payments related to the founding members’ on-screen advertising commitments under their beverage concessionaire agreements for encumbered theaters. These payments are also accounted for as a reduction to the intangible asset. During the three months ended June 28, 2018 and June 29, 2017 and the six months ended June 28, 2018 and June 29, 2017 , the Company recorded a reduction to net intangible assets of $5.6 million , $4.3 million , $ 7.8 million and $4.7 million , respectively, related to integration and other encumbered theater payments. These payments received from AMC related to their acquisitions of theaters from Carmike and Rave Cinemas and from Cinemark related primarily to their acquisition of theaters from Rave Cinemas. During the three months ended June 28, 2018 and June 29, 2017 and the six months ended June 28, 2018 and June 29, 2017 , AMC and Cinemark paid a total of $2.2 million , $0.5 million , $11.5 million and $1.5 million , respectively, in integration and other encumbered theater payments (as payments are made one quarter and one month in arrears, respectively). If common membership units are issued to a founding member for newly acquired theaters that are subject to an existing on-screen advertising agreement with an alternative provider, the amortization of the intangible asset commences after the existing agreement expires and NCM LLC can utilize the theaters for all of its services.

Related Party Transactions [Abstract]
Related Party Transactions	RELATED PARTY TRANSACTIONS Founding Member Transactions —In connection with NCM, Inc.’s IPO, the Company entered into several agreements to define and regulate the relationships among NCM, Inc., NCM LLC and the founding members. They include the following: • ESAs. Under the ESAs, NCM LLC is the exclusive provider within the United States of advertising services in the founding members’ theaters (subject to pre-existing contractual obligations and other limited exceptions for the benefit of the founding members). The advertising services include the use of the digital content network (“DCN”) equipment required to deliver the on-screen advertising and other content included in the Noovie pre-show, use of the LEN and rights to sell and display certain lobby promotions. Further, 30 to 60 seconds of advertising included in the Noovie pre-show is sold to NCM LLC’s founding members to satisfy the founding members’ on-screen advertising commitments under their beverage concessionaire agreements. In consideration for access to the founding members’ theaters, theater patrons, the network equipment required to display on-screen and LEN video advertising and the use of theaters for lobby promotions, the founding members receive a monthly theater access fee. • Common Unit Adjustment Agreement. The Common Unit Adjustment Agreement provides a mechanism for increasing or decreasing the membership units held by the founding members based on the acquisition or construction of new theaters or sale or closure of theaters that are operated by each founding member and included in NCM LLC’s network. • Tax Receivable Agreement. The tax receivable agreement provides for the effective payment by NCM, Inc. to the founding members of 90% of the amount of cash savings, if any, in U.S. federal, state and local income tax or franchise tax that is actually realized as a result of certain increases in NCM, Inc.’s proportionate share of tax basis in NCM LLC’s tangible and intangible assets resulting from the IPO and related transactions. • Software License Agreement.

Mandatory distributions of available cash for the three and six months ended June 28, 2018 and June 29, 2017 were as follows (in millions): Three Months Ended Six Months Ended June 28, June 29, June 28, June 29, AMC $ — $ 6.2 $ 2.2 $ 8.2 Cinemark 8.3 4.5 11.3 6.0 Regal 8.6 4.5 11.8 6.0 Total founding members 16.9 15.2 25.3 20.2 NCM, Inc. 16.2 9.9 24.3 13.1 Total $ 33.1 $ 25.1 $ 49.6 $ 33.3 The mandatory distributions of available cash by NCM LLC to its founding members for the three months ended June 28, 2018 of $16.9 million is included in amounts due to founding members, net on the unaudited Condensed Consolidated Balance Sheets as of June 28, 2018 and will be made in the third quarter of 2018. AMC’s distribution for the three months ended June 28, 2018 was split equally between Cinemark and Regal because NCM LLC used a record date of July 6, 2018 (following the sale of AMC's membership units to Cinemark and Regal) to accommodate an agreement between AMC and Cinemark and AMC and Regal. These agreements entitle AMC to half of the second quarter of 2018 available cash distribution, or approximately $2.2 million , of which Cinemark and Regal will each independently pay AMC approximately $1.1 million . The mandatory distributions to NCM, Inc. are eliminated in consolidation. Amounts due to founding members, net as of June 28, 2018 were comprised of the following (in millions): AMC Cinemark Regal Total Theater access fees, net of beverage revenues and other encumbered theater payments $ 1.7 $ 1.1 $ 1.7 $ 4.5 Distributions payable to founding members — 8.3 8.6 16.9 Integration payments due from founding members (4.8 ) (0.3 ) — (5.1 ) Cost and other reimbursement — 0.1 — 0.1 Total amounts due (from) to founding members, net $ (3.1 ) $ 9.2 $ 10.3 $ 16.4 Amounts due to founding members, net as of December 28, 2017 were comprised of the following (in millions): AMC Cinemark Regal Total Theater access fees, net of beverage revenues and other encumbered theater payments $ 1.5 $ 1.0 $ 1.5 $ 4.0 Distributions payable to founding members 10.8 13.5 13.3 37.6 Integration payments due from founding members (8.5 ) (0.4 ) — (8.9 ) Total amounts due to founding members, net $ 3.8 $ 14.1 $ 14.8 $ 32.7 As of June 28, 2018 , AMC owned no shares of NCM, Inc. common stock. However, during the three and six months ended June 28, 2018 and June 29, 2017 , AMC received cash dividends of approximately $0.1 million , $0.0 million , $0.3 million and $0.1 million , respectively, on its shares of NCM, Inc. common stock sold prior to June 28, 2018. AC JV, LLC Transactions —In December 2013, NCM LLC sold its Fathom Events business to a newly formed limited liability company, AC JV, LLC, owned 32% by each of the founding members and 4% by NCM LLC. The Company accounts for its investment in AC JV, LLC under the equity method of accounting in accordance with ASC 323-30, Investments—Equity Method and Joint Ventures (“ASC 323-30”) because AC JV, LLC is a limited liability company with the characteristics of a limited partnership and ASC 323-30 requires the use of equity method accounting unless the Company’s interest is so minor that it would have virtually no influence over partnership operating and financial policies. Although NCM LLC does not have a representative on AC JV, LLC’s Board of Directors or any voting, consent or blocking rights with respect to the governance or operations of AC JV, LLC, the Company concluded that its interest was more than minor under the accounting guidance. The Company’s investment in AC JV, LLC was $1.1 million and $1.0 million as of June 28, 2018 and December 28, 2017 , respectively. Equity in earnings from AC JV, LLC for the three months ended June 28, 2018 and June 29, 2017 and the six months ended June 28, 2018 and June 29, 2017 , were $0.1 million , $0.0 million , $0.1 million and $0.1 million , respectively, and is included in non-operating expenses in the unaudited Condensed Consolidated Statements of Income. NCM LLC also received fees from AC JV, LLC of $0.1 million , $0.2 million , $0.1 million , and $0.2 million in the three months ended June 28, 2018 and June 29, 2017 and the six months ended June 28, 2018 and June 29, 2017 related to the transition services agreement with ACJV whereby the Company provides certain corporate overhead or creative services or use of facilities in exchange for a fee. These fees received by NCM LLC are included as an offset to network costs in the unaudited Condensed Consolidated Statements of Income.

If the Senior Secured Notes are not refinanced on or prior to October 30, 2021, then the revolving credit facility and term loan will instead mature on December 30, 2021. The maturity dates for the revolving credit facility and term loan as of December 28, 2017 are described below. (2) The interest rates on the revolving credit facility and term loans are described below. Senior Secured Credit Facility —On June 20, 2018, the Company entered into a credit agreement to replace NCM LLC's senior secured credit facility, dated as of February 13, 2007, as amended (the “previous facility”). Consistent with the structure of the previous facility, the agreement consists of a term loan facility and a revolving credit facility. As of June 28, 2018 , NCM LLC’s senior secured credit facility consisted of a $175.0 million revolving credit facility and a $270.0 million term loan. The obligations under the senior secured credit facility are secured by a lien on substantially all of the assets of NCM LLC. During the second quarter of 2018, the Company capitalized approximately $6.5 million of debt issuance costs related to the new revolving credit facility and the term loan. The Company also recognized $1.2 million in non-operating loss related to the write-off of capitalized debt issuance costs related to the previous facility and recognition of debt issuance costs that did not qualify for capitalization. Revolving Credit Facility —The revolving credit facility portion of NCM LLC’s total borrowings is available, subject to certain conditions, for general corporate purposes of NCM LLC in the ordinary course of business and for other transactions permitted under the senior secured credit facility, and a portion is available for letters of credit. As of June 28, 2018 , NCM LLC’s total availability under the $175.0 million revolving credit facility was $140.0 million , net of $30.2 million outstanding and $4.8 million in letters of credit. The unused line fee is 0.50% per annum which is consistent with the previous facility. Borrowings under the revolving credit facility bear interest at NCM LLC’s option of either the LIBOR index plus an applicable margin ranging from 1.75% to 2.25% or the base rate plus an applicable margin ranging from 0.75% to 1.25% . The margin changed to the aforementioned range from a fixed margin of LIBOR index plus 2.00% or the base rate plus 1.00% . The applicable margin for the revolving credit facility is determined quarterly and is subject to adjustment based upon a consolidated net senior secured leverage ratio for NCM LLC (the ratio of secured funded debt less unrestricted cash and cash equivalents of up to $100.0 million , divided by Adjusted OIBDA). The revolving credit facility will mature on June 20, 2023 contingent upon the refinancing of NCM LLC’s Notes due 2022 (defined below, see “Senior Secured Notes due 2022”) on or prior to October 30, 2021. If the Notes due 2022 are not refinanced on or prior to October 30, 2021, then the revolving credit facility will instead mature on December 30, 2021. Term Loans —The interest rate on the term loans is a rate chosen at NCM LLC’s option of either the LIBOR index plus 3.00% or the base rate plus 2.00% . The rate increased from LIBOR index plus 2.75% or the base rate plus 1.75% . The weighted-average interest rate on the term loans as of June 28, 2018 was 5.1% . The term loan amortizes at a rate equal to 1.00% annually, to be paid in equal quarterly installments. The term loan will mature on June 20, 2025 contingent upon the refinancing of the Notes due 2022 on or prior to October 30, 2021. If the Notes due 2022 are not refinanced on or prior to October 30, 2021, then the term loan will instead mature on December 30, 2021. The senior secured credit facility contains a number of covenants and various financial ratio requirements, including, (i) a consolidated net total leverage ratio covenant of 6.25 times for each quarterly period (commencing with the quarterly period ending September 30, 2018) and (ii) with respect to the revolving credit facility, maintaining a consolidated net senior secured leverage ratio of equal to or less than 4.50 times on a quarterly basis for each quarterly period (beginning with the quarterly period ending September 30, 2018) in which a balance is outstanding on the revolving credit facility. In addition, NCM LLC is permitted to make quarterly dividend payments and other restricted payments with its available cash as long as NCM LLC’s consolidated net senior secured leverage ratio (after giving effect to any such payment) is below 5.50 times and no default or event of default has occurred and continues to occur under the senior secured credit facility. As of June 28, 2018, NCM LLC’s consolidated net senior secured leverage ratio was 2.9 times (versus the dividend payment restriction of 5.50 times and the covenant of 4.50 times) and NCM LLC's consolidated net total leverage ratio was 4.0 times (versus the covenant of 6.25 times). Senior Secured Notes due 2022 —On April 27, 2012, NCM LLC completed a private placement of $400.0 million in aggregate principal amount of 6.000% Senior Secured Notes (the “Notes due 2022”) for which the registered exchange offering was completed on November 26, 2012. The Notes due 2022 pay interest semi-annually in arrears on April 15 and October 15 of each year, which commenced on October 15, 2012 . The Notes due 2022 were issued at 100% of the face amount thereof and are senior secured obligations of NCM LLC, rank the same as NCM LLC’s senior secured credit facility, subject to certain exceptions, and share in the same collateral that secures NCM LLC’s obligations under the senior secured credit facility. Senior Unsecured Notes due 2026 —On August 19, 2016, NCM LLC completed a private placement of $250.0 million in aggregate principal amount of 5.750% Senior Unsecured Notes (the “Notes due 2026”) for which the registered exchange offering was completed on November 8, 2016. The Notes due 2026 pay interest semi-annually in arrears on February 15 and August 15 of each year, which commenced on February 15, 2017 . The Notes due 2026 were issued at 100% of the face amount thereof and are the senior unsecured obligations of NCM LLC and will be effectively subordinated to all existing and future secured debt, including the Notes due 2022, NCM LLC’s senior secured credit facility and any future asset backed loan facility. The Notes due 2026 rank equally in right of payment with all of NCM LLC’s existing and future senior indebtedness, including the Notes due 2022, NCM LLC’s existing senior secured credit facility, and any future asset backed loan facility, in each case, without giving effect to collateral arrangements.

Income Tax Disclosure [Abstract]
Income Taxes	7. INCOME TAXES Uncertain Tax Positions —The Company is subject to taxation in the U.S. and various states. The Company has established a contingency reserve for material, known tax exposures. The Company’s reserve reflects management’s judgment as to the resolution of the issues involved if subject to judicial review or other settlement. While the Company believes its reserves are adequate to cover reasonably expected tax risks, there can be no assurance that, in all instances, an issue raised by a tax authority will be resolved at a financial cost that does not exceed its related reserve. With respect to the reserve, the Company’ income tax expense would include (i) any changes in tax reserves arising from material changes during the period in the facts and circumstances (i.e., new information) surrounding a tax issue and (ii) any difference from the Company’s tax position as recorded in the financial statements and the final resolution of a tax issue during the period. Such resolution could materially increase or decrease income tax expense in the unaudited Condensed Consolidated Financial Statements in future periods and could impact operating cash flows. Unrecognized tax benefits represent the aggregate tax effect of differences between tax return positions and the amounts otherwise recognized in the unaudited Condensed Consolidated Financial Statements. The total amount of unrecognized tax benefits as of June 28, 2018 and December 28, 2017 , was $0.3 million and $0.3 million , respectively, excluding accrued interest and penalties, which if recognized would affect the effective tax rate. The Company recognizes interest and penalties with respect to unrecognized tax benefits in income tax expense in the unaudited Condensed Consolidated Statements of Income and records the liability in income taxes payable in the unaudited Condensed Consolidated Balance Sheets. The Company recognized an inconsequential amount in interest and penalties during the three and six months ended June 28, 2018 and June 29, 2017 , respectively. The Company has accrued $0.1 million and $0.1 million for the payment of interest and penalties as of June 28, 2018 and December 28, 2017 , respectively. As of June 28, 2018 , the Company’s reserve for unrecognized tax benefits was $0.3 million . It is reasonably possible that this reserve will decrease by this amount to $0.0 million in the next twelve months due to the expiration of certain statutes of limitations. Tax Reform —On December 22, 2017, the U.S. government enacted the Tax Act which makes broad and complex changes to the U.S. tax code that will affect the Company’s fiscal year ending December 27, 2018, including, but not limited to, (1) reducing the U.S. federal corporate tax rate, (2) allowing full expensing of qualified property, (3) creating a new limitation on deductible interest expense; (4) changing rules related to uses and limitations of net operating loss carryforwards created in tax years beginning after December 31, 2017, and (5) limiting the amount of compensation that can be deducted for highly compensated officers by terminating the exclusion of performance-based compensation from the $1 million per employee, per year limitation. Following the enactment of the Tax Act, the SEC staff issued SAB 118 which provides guidance on accounting for the tax effects of the Tax Act. SAB 118 provides a measurement period that should not extend beyond one year from the Tax Act enactment date for companies to complete the accounting under ASC 740. While the Company is able to make a reasonable estimate of the impact of the reduction in the corporate tax rate, the Company’s accounting for various elements of the Tax Act may be affected by other related analysis including, but not limited to, bonus depreciation that will allow for immediate expensing of qualified property and the state tax effect of adjustments made to federal temporary differences. As such, the impact of the Tax Act is an estimate pending further information and the analysis noted. Tax Receivable Agreement —Subsequent to the issuance of the December 28, 2017 financial statements, an immaterial error was identified within the payable to the founding members under the TRA related to the Company's application of tax reform and the federal tax rate applied to the 2018 TRA payment for the 2017 fiscal year. In the three and six months ended June 28, 2018, the Company recorded a loss within the gain (loss) on re-measurement of the payable to founding members under the TRA and a corresponding increase in the payable to founding members under the TRA of $8.6 million as well as an increase to deferred tax assets and a decrease to deferred tax expense of approximately $2.2 million related to the correction of the immaterial error. The error does not impact the amount of cash TRA payments made to the founding members for any historical period, the timing of those payments, or future calculations of payments due under the TRA. Changes in the Company’s Effective Tax Rate —The Company’s effective tax rate increased from (5.4)% for the six months ended June 29, 2017 to 88.1% for the six months ended June 28, 2018 primarily due to tax expense recorded in the six months ended June 28, 2018 related to the decrease in the Company's deferred rate due to a change in state tax law regarding income sourcing and the permanent difference between the allowable deduction for stock based compensation for tax purposes (valued based upon the stock price at vesting) and book purposes (valued based upon the stock price at grant) due to the decline in the Company’s stock price subsequent to the grant of the shares. This rate increase was partially offset by a 13.5% decrease in the Company’s current rate following the enactment of the Tax Cuts and Jobs Act by the US government on December 22, 2017.

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	8. COMMITMENTS AND CONTINGENCIES Legal Actions —The Company is subject to claims and legal actions in the ordinary course of business. The Company believes such claims will not have a material effect individually and in the aggregate on its financial position, results of operations or cash flows. Minimum Revenue Guarantees ―As part of the network affiliate agreements entered into in the ordinary course of business under which the Company sells advertising for display in various network affiliate theater chains, the Company has agreed to certain minimum revenue guarantees on a per attendee basis. If a network affiliate achieves the attendance set forth in their respective agreement, the Company has guaranteed minimum revenue for the network affiliate per attendee if such amount paid under the revenue share arrangement is less than its guaranteed amount. As of June 28, 2018 , the maximum potential amount of future payments the Company could be required to make pursuant to the minimum revenue guarantees is $79.5 million over the remaining terms of the network affiliate agreements. These minimum guarantees relate to various affiliate agreements ranging in term from one to twenty years , prior to any renewal periods of which some are at the option of the Company. During the three and six months ended June 28, 2018 and June 29, 2017 , the Company made no payments related to these minimum guarantees. For these periods, there are no other affiliate agreements with guaranteed minimums in excess of the revenue share arrangement. Theater Access Fee Guarantees —In consideration for NCM LLC’s access to the founding members’ theater attendees for on-screen advertising and use of lobbies and other space within the founding members’ theaters for the LEN and lobby promotions, the founding members receive a monthly theater access fee under the ESAs. The theater access fee is composed of a fixed payment per patron, a fixed payment per digital screen (connected to the DCN) and a fee for access to higher quality digital cinema equipment. The payment per theater patron increases by 8% every five years , with this increase last occurring in fiscal year 2017, and the payment per digital screen and for digital cinema equipment increasing annually by 5% . The theater access fee paid in the aggregate to all founding members cannot be less than 12% of NCM LLC’s aggregate advertising revenue (as defined in the ESA), or it will be adjusted upward to reach this minimum payment. As of June 28, 2018 and December 28, 2017 , the Company had no liabilities recorded for the minimum payment, as the theater access fee was in excess of the minimum.

Fair Value Measurements

Fair Value Disclosures [Abstract]
Fair Value Measurements	9. FAIR VALUE MEASUREMENTS Fair value is the price that would be received from selling an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. Fair value is estimated by applying the following hierarchy, which prioritizes the inputs used to measure fair value into three levels and bases the categorization within the hierarchy upon the lowest level of input that is available and significant to the fair value measurement: Level 1 —Quoted prices in active markets for identical assets or liabilities. Level 2 —Observable inputs other than quoted prices in active markets for identical assets and liabilities, quoted prices for identical or similar assets or liabilities in inactive markets, or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities. Level 3 —Inputs that are generally unobservable and typically reflect management’s estimate of assumptions that market participants would use in pricing the asset or liability. Non-Recurring Measurements —Certain assets are measured at fair value on a non-recurring basis. These assets are not measured at fair value on an ongoing basis but are subject to fair value adjustments in certain circumstances. These assets include long-lived assets, intangible assets, other investments, notes receivable and borrowings. Long-Lived Assets, Intangible Assets, Other Investments and Notes Receivable —The Company regularly reviews long-lived assets (primarily property, plant and equipment), intangible assets, investments accounted for under the cost or equity method and notes receivable for impairment whenever certain qualitative factors, events or changes in circumstances indicate that the carrying amounts of the assets may not be fully recoverable. When the estimated fair value is determined to be lower than the carrying value of the asset, an impairment charge is recorded to write the asset down to its estimated fair value. Other investments consisted of the following (in millions): As of June 28, December 28, Investment in AC JV, LLC (1) $ 1.1 $ 1.0 Other investments (2) 2.1 2.5 Total $ 3.2 $ 3.5 _______________________________________ (1) Refer to Note 5— Related Party Transactions . This investment is accounted for utilizing the equity method. (2) The Company received equity securities in privately held companies as consideration for a portion of advertising contracts. The equity securities are accounted for at adjusted cost in accordance with the practicability exception under ASU 2016-1 and represent an ownership of less than 20% . The Company does not exert significant influence on these companies’ operating or financial activities. During the three months ended June 28, 2018 and June 29, 2017 and six months ended June 28, 2018 and June 29, 2017 , the Company recorded impairment charges of $0.0 million , $1.7 million , $0.4 million and $3.1 million , respectively, on certain of its investments due to a significant deterioration in the business prospects of the investee or new information regarding the fair value of the investee, which brought the total remaining value of the respective impaired investments to $0.0 million as of June 28, 2018 and $0.1 million as of June 29, 2017 . As of June 28, 2018 , no other observable price changes or impairments have been recorded as a result of the Company’s qualitative assessment of identified events or changes in the circumstances of the remaining investments. The investment in AC JV, LLC was initially valued using comparative market multiples. The other investments were recorded based upon the fair value of the services provided in exchange for the investment. As the inputs to the determination of fair value are based upon non-identical assets and use significant unobservable inputs, they have been classified as Level 3 in the fair value hierarchy. As of June 28, 2018 and December 28, 2017 , the Company had notes receivable totaling $8.3 million and $8.3 million , respectively, from its founding members related to the sale of Fathom Events, as described in Note 5— Related Party Transactions . These notes were initially valued using comparative market multiples. There were no identified events or changes in circumstances that had a significant adverse effect on the fair value of the notes receivable. The notes are classified as Level 3 in the fair value hierarchy as the inputs to the determination of fair value are based upon non-identical assets and use significant unobservable inputs. Borrowings —The carrying amount of the revolving credit facility is considered a reasonable estimate of fair value due to its floating-rate terms. The estimated fair values of the Company’s financial instruments where carrying values do not approximate fair value were as follows (in millions): As of June 28, As of December 28, Carrying Value Fair Value (1) Carrying Value Fair Value (1) Term loan $ 270.0 $ 270.7 $ 270.0 $ 270.8 Notes due 2022 400.0 407.3 400.0 407.3 Notes due 2026 250.0 230.2 250.0 235.0 ____________________________________________ (1) If the Company were to measure the borrowings in the above table at fair value on the balance sheet they would be classified as Level 2 based upon the inputs utilized. Recurring Measurements —The fair values of the Company’s assets and liabilities measured on a recurring basis pursuant to ASC 820-10, Fair Value Measurements and Disclosures are as follows (in millions): Fair Value Measurements at Reporting Date Using Fair Value as of June 28, Quoted Prices in Active Markets for Identical Assets Significant Other Significant Unobservable Inputs ASSETS: Cash equivalents (1) $ 20.7 $ 10.2 $ 10.5 $ — Short-term marketable securities (2) 18.0 — 18.0 — Long-term marketable securities (2) 13.2 — 13.2 — Total assets $ 51.9 $ 10.2 $ 41.7 $ — Fair Value Measurements at Reporting Date Using Fair Value as of December 28, Quoted Prices in Active Markets for Identical Assets Significant Other Significant Unobservable Inputs ASSETS: Cash equivalents (1) $ 12.2 $ 8.2 $ 4.0 $ — Short-term marketable securities (2) 13.1 — 13.1 — Long-term marketable securities (2) 16.2 — 16.2 — Total assets $ 41.5 $ 8.2 $ 33.3 $ — ___________________________________________ (1) Cash Equivalents —The Company’s cash equivalents are carried at estimated fair value. Cash equivalents consist of money market accounts which the Company has classified as Level 1 given the active market for these accounts and commercial paper with original maturities of three months or less, which are classified as Level 2 and are valued as described below. (2) Short-Term and Long-Term Marketable Securities —The carrying amount and fair value of the marketable securities are equivalent since the Company accounts for these instruments at fair value. The Company’s government agency bonds, commercial paper and certificates of deposit are valued using third party broker quotes. The value of the Company’s government agency bonds is derived from quoted market information. The inputs in the valuation are classified as Level 1 if there is an active market for these securities; however, if an active market does not exist, the inputs are recorded at a lower level in the fair value hierarchy. The value of commercial paper and certificates of deposit is derived from pricing models using inputs based upon market information, including contractual terms, market prices and yield curves. The inputs to the valuation pricing models are observable in the market, and as such are generally classified as Level 2 in the fair value hierarchy. For the three and six months ended June 28, 2018 and June 29, 2017 , there was an inconsequential amount of net realized gains (losses) recognized in interest income and an inconsequential amount of net unrealized holding gains (losses) included in other comprehensive income. Original cost of short-term marketable securities is based on the specific identification method. As of June 28, 2018 and December 28, 2017 , there was $0.2 million and $0.2 million , respectively, of gross unrealized losses related to individual securities of $8.2 million and $8.2 million , respectively, that had been in a continuous loss position for 12 months or longer. The Company has the intention and ability to hold these securities to maturity. The amortized cost basis, aggregate fair value and maturities of the marketable securities the Company held as of June 28, 2018 and December 28, 2017 were as follows: As of June 28, 2018 Amortized Cost Aggregate Fair Maturities (1) MARKETABLE SECURITIES: Short-term municipal bonds $ 0.5 $ 0.5 0.6 Short-term U.S. government agency bonds 3.6 3.6 0.5 Short-term commercial paper: Financial 2.0 2.0 0.3 Industrial 7.9 8.0 0.1 Utility 2.0 2.0 0.1 Short-term certificates of deposit 1.9 1.9 0.5 Total short-term marketable securities $ 17.9 $ 18.0 Long-term municipal bonds 1.3 1.3 2.0 Long-term U.S. government agency bonds 9.0 8.8 2.2 Long-term certificates of deposit 3.1 3.1 1.5 Total long-term marketable securities $ 13.4 $ 13.2 Total marketable securities $ 31.3 $ 31.2 As of December 28, 2017 Amortized Cost Aggregate Fair Maturities (1) MARKETABLE SECURITIES: Short-term U.S. government agency bonds 2.3 2.2 0.9 Short-term certificates of deposit 0.9 0.9 0.8 Short-term commercial paper: Financial 6.0 6.0 0.3 Industrial 4.0 4.0 0.3 Total short-term marketable securities 13.2 13.1 Long-term municipal bonds 1.9 1.9 2.1 Long-term U.S. government agency bonds 10.4 10.2 2.5 Long-term certificates of deposit 4.1 4.1 1.8 Total long-term marketable securities 16.4 16.2 Total marketable securities $ 29.6 $ 29.3 ___________________________________ (1) Maturities —Securities available for sale include obligations with various contractual maturity dates some of which are greater than one year.

SUBSEQUENT EVENT On July 5, 2018 and subsequent to the end of the second quarter of 2018, AMC closed on the sale of 100.0% of its remaining NCM LLC membership units to Regal and Cinemark, increasing Regal and Cinemark's ownership percentages to 26.1% and 25.1% , respectively. Despite not having any ownership interests in NCM LLC, AMC remains a party to the ESA, Common Unit Adjustment Agreement, TRA and certain other original agreements, and AMC will continue to be a participant in the annual Common Unit Adjustment, recipient of TRA payments and theater access fees, among other things. Due to not having ownership in NCM LLC, AMC will not be a member under the terms of the NCM LLC Operating Agreement, and thus AMC will not receive available cash distributions or allocation of earnings and losses in NCM LLC, unless its ownership increases pursuant to a Common Unit Adjustment. Further, the sale does not impact future integration payments owed to NCM LLC by AMC. On August 6, 2018 , the Company declared a cash dividend of $0.17 per share (approximately $13.1 million ) on each share of the Company’s common stock (not including outstanding restricted stock which will accrue dividends until the shares vest) to stockholders of record on August 16, 2018 to be paid on August 31, 2018.

Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation The Company has prepared the unaudited Condensed Consolidated Financial Statements and related notes of NCM, Inc. in accordance with accounting principles generally accepted in the United States of America (“GAAP”) for interim financial information and the rules and regulations of the Securities and Exchange Commission (“SEC”). Accordingly, certain information and footnote disclosures typically included in an annual report have been condensed or omitted for this quarterly report. The balance sheet as of December 28, 2017 is derived from the audited financial statements of NCM, Inc. Therefore, the unaudited Condensed Consolidated Financial Statements should be read in conjunction with the audited Consolidated Financial Statements and notes thereto included in the Company’s annual report on Form 10-K filed for the fiscal year ended December 28, 2017 . In the opinion of management, all adjustments necessary to present fairly in all material respects the financial position, results of operations and cash flows for all periods presented have been made. The Company’s business is seasonal and for this and other reasons operating results for interim periods may not be indicative of the Company’s full year results or future performance. As a result of the various related party agreements discussed in Note 5— Related Party Transactions , the operating results as presented are not necessarily indicative of the results that might have occurred if all agreements were with non-related third parties. The Company manages its business under one reportable segment of advertising.
Estimates	Estimates —The preparation of the financial statements in conformity with GAAP requires management to make 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 period. Significant estimates include those related to the reserve for uncollectible accounts receivable, share-based compensation and income taxes. Actual results could differ from those estimates.
Revenue Recognition	Revenue Recognition —The Company derives revenue principally from the advertising business, which includes on-screen and lobby network (LEN) advertising and lobby promotions and advertising on entertainment websites and mobile applications owned by NCM LLC and other companies. Revenue is recognized over time as the customer receives the benefits provided by NCM LLC’s advertising services and the Company has the right to payment for performance to date. The Company considers the terms of each arrangement to determine the appropriate accounting treatment as more fully discussed in Note 2 - Revenue from Contracts with Customers .
Concentration of Credit Risk and Significant Customers	Concentration of Credit Risk and Significant Customers —Bad debts are provided for using the allowance for doubtful accounts method based on historical experience and management’s evaluation of outstanding receivables at the end of the period. Receivables are written off when management determines amounts are uncollectible. Trade accounts receivable are uncollateralized and represent a large number of geographically dispersed debtors. The collectability risk with respect to national and regional advertising is reduced by transacting with founding members or large, national advertising agencies that have strong reputations in the advertising industry and clients with stable financial positions. The Company has smaller contracts with thousands of local clients that are not individually significant. As of June 28, 2018 and December 28, 2017 , there were no advertising agency groups or individual customers through which the Company sources national advertising revenue representing more than 10% of the Company’s outstanding gross receivable balance. During the three and six months ended June 28, 2018 and June 29, 2017 , the Company had no customers that accounted for more than 10% of revenue.
Share-Based Compensation	Share-Based Compensation —The Company has issued stock options and restricted stock to certain employees and restricted stock units to its independent directors. The Company has not granted stock options since 2012. In 2017 and 2018, the restricted stock grants for Company officers vest upon the achievement of Company performance measures and/or service conditions, while non-officer grants vest only upon the achievement of service conditions. Compensation expense of restricted stock that vests upon the achievement of Company performance measures is based on management’s financial projections and the probability of achieving the projections, which require considerable judgment. A cumulative adjustment is recorded to share-based compensation expense in periods that management changes its estimate of the number of shares of restricted stock expected to vest. Ultimately, the Company adjusts the expense recognized to reflect the actual vested shares following the resolution of the performance conditions. Dividends are accrued when declared on unvested restricted stock that is expected to vest and are only paid with respect to shares that actually vest. During the three and six months ended June 28, 2018 and June 29, 2017 , 19,357 , 29,759 , 975,596 and 1,008,118 shares of restricted stock and restricted stock units vested, respectively. During the three and six months ended June 28, 2018 , and June 29, 2017 , 0 , 0 , 0 , and 58,450 stock options were exercised at a weighted average exercise price of $0.00 , $0.00 , $ 0.00 and $ 11.04 per share.
Consolidation	Consolidation —NCM, Inc. consolidates the accounts of NCM LLC under the provisions of ASC 810, Consolidation (“ASC 810”). The following table presents the changes in NCM, Inc.’s equity resulting from net income attributable to NCM, Inc. and transfers to or from noncontrolling interests (in millions): Six Months Ended June 28, June 29, Net income attributable to NCM, Inc. $ 2.3 $ 3.9 NCM LLC equity issued for purchase of intangible asset 7.7 78.8 Income tax and other impacts of subsidiary ownership changes (3.1 ) (46.0 ) Change from net loss attributable to NCM, Inc. and transfers from noncontrolling interests $ 6.9 $ 36.7
Recently Adopted Accounting Pronouncements	Recently Adopted Accounting Pronouncements During the first quarter of 2018, the Company adopted Accounting Standards Update 2014-9, Revenue from Contracts with Customers (Topic 606) (“ASU 2014-9”) using the modified retrospective transition method. The Company identified the same performance obligations under ASU 2014-9 as compared with deliverables and separate units of account previously identified. ASU 2014-9 impacted the accounting for barter transactions where the Company exchanges advertising time for products and services used principally for selling and marketing activities. The Company historically recognized revenue for these transactions at the estimated fair value of the advertising exchanged based on the fair value received for similar advertising from cash paying customers. In accordance with the new guidance, the Company will recognize revenue for these transactions based upon the fair value of the products and services received, rather than the value of the advertising provided. The modified retrospective transition method allows entities to apply the new revenue standard prospectively and record a cumulative-effect adjustment to the opening balance of retained earnings in the period the new revenue standard is first applied. Upon the adoption of ASU 2014-9 on December 29, 2017, the Company recorded a $0.2 million cumulative-effect adjustment related to the change in accounting for barter transactions on contracts that are not completed as of December 29, 2017 in the unaudited Consolidated Balance Sheet. The Company’s adoption of ASU 2014-9 did not have a material impact on the unaudited Condensed Consolidated Financial Statements. The Company has incorporated additional disclosures in Note 2 – Revenue from Contracts with Customers to the unaudited Condensed Consolidated Financial Statements to comply with ASU 2014-9. During the first quarter of 2018, the Company adopted Accounting Standards Update 2016-1, Recognition and Measurement of Financial Assets and Financial Liabilities (“ASU 2016-1”), which requires equity investments that are not accounted for under the equity method of accounting to be measured at fair value with changes recognized in earnings (rather than reported through other comprehensive income) and updates certain presentation and disclosure requirements. In February 2018, the FASB issued Accounting Standards Update 2018-3, Technical Corrections and Improvements to Financial Instruments – Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities (“ASU 2018-3”). These amendments clarify the guidance on certain topics referred to in ASU 2016-1. The Company has incorporated changes to the methodology utilized to value the Company’s investments and changes to disclosures in its notes to the unaudited Condensed Consolidated Financial Statements to comply with ASU 2016-1. During the first quarter of 2018, the Company adopted Accounting Standards Update 2016-15, Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments (“ASU 2016-15”) on a retrospective basis. ASU 2016-15 provides guidance on certain cash receipts and cash payments presented and classified in the statement of cash flows. The adoption of ASU 2016-15 did not have a material impact on the unaudited Condensed Consolidated Financial Statements or notes thereto. During the first quarter of 2018, the Company adopted Accounting Standards Update 2016-18, Statement of Cash Flows (Topic 230): Restricted Cash (“ASU 2016-18”) on a retrospective basis. ASU 2016-18 requires that the reconciliation of the beginning-of-period and end-of-period amounts shown in the statement of cash flows include restricted cash and restricted cash equivalents. The Company has adjusted the Condensed Consolidated Statement of Cash Flow for the six months ended June 29, 2017 to include the restricted cash balance within the aforementioned captions. The adoption of ASU 2016-18 had no other impact on the unaudited Condensed Consolidated Financial Statements or notes thereto.
Recently Issued Accounting Pronouncements	Recently Issued Accounting Pronouncements In February 2016, the FASB issued Accounting Standards Update 2016-2, Leases (Topic 842) (“ASU 2016-2”). ASU 2016-2 establishes a right-of-use (“ROU”) model that requires a lessee to record a ROU asset and a lease liability on the balance sheet for all leases with terms longer than twelve months. Leases will be classified as either finance or operating, with classification affecting the pattern of expense recognition in the income statement. The new standard is effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. A modified retrospective transition approach is required for lessees for capital and operating leases existing at, or entered into after, the beginning of the earliest comparative period presented in the financial statements, with certain practical expedients available. The Company is currently evaluating the impact that adopting this guidance will have on the unaudited Condensed Consolidated Financial Statements or notes thereto and will adopt its provisions effective January 1, 2019. The Company expects to utilize the following practical expedients: (i) not being required to reassess whether any expired or existing contracts are or contain leases; (ii) not being required to reassess the lease classification for any expired or existing leases (that is, all existing leases that were classified as operating leases in accordance with Topic 840 will be classified as operating leases, and all existing leases that were classified as capital leases in accordance with Topic 840 will be classified as finance leases); and (iii) not being required to reassess initial direct costs for any existing leases. The Company is still evaluating the remaining practical expedients. In June 2016, the FASB issued Accounting Standards Update 2016-13, Financial Instruments – Credit Losses (Topic 326), Measurement of Credit Losses on Financial Statements (“ASU 2016-13”), which requires a financial asset (or group of financial assets) measured at amortized cost basis to be presented at the net amount expected to be collected. The allowance for credit losses is a valuation account that is deducted from the amortized cost basis of the financial asset(s) to present the net carrying value at the amount expected to be collected on the financial asset. ASU 2016-13 is effective for fiscal years beginning after December 15, 2019, including interim periods within those fiscal years, with early adoption permitted and is to be adopted on a modified retrospective basis. The Company is currently evaluating the impact that adopting this guidance will have on the unaudited Condensed Consolidated Financial Statements or notes thereto. In March 2018, the FASB issued Accounting Standards Update 2018-4, Investments – Debt Securities (Topic 320) and Regulated Operations (Topic 980): Amendments to SEC Paragraphs Pursuant to SEC Staff Accounting Bulletin No. 117 and SEC Release No. 33-9273 (“ASU 2018-4”), which amends and supersedes variance paragraphs that contain SEC guidance in ASC 320, Investments-Debt Securities and ASC 980, Regulated Operations . The Company is currently evaluating the impact that adopting this guidance will have on the unaudited Condensed Consolidated Financial Statements or notes thereto. In June 2018, the FASB issued Accounting Standards Update 2018-7, Compensation – Stock Compensation (Topic 718): Improvements to Nonemployee Share-Based Payment Accounting (“ASU 2018-7”), which amends Topic 718 to include share-based payment transactions for acquiring goods and services from nonemployees. ASU 2018-7 is effective for fiscal years beginning December 15, 2018, with early adoption permitted. The Company is currently evaluating the impact that adopting this guidance will have on the unaudited Condensed Consolidated Financial Statements or notes thereto. The Company has considered all other recently issued accounting pronouncements and does not believe the adoption of such pronouncements will have a material impact on its unaudited Condensed Consolidated Financial Statements or notes thereto.
Change in Accounting Principle and Correction of an Error	Change in Accounting Principle and Correction of an Error During the first quarter of 2018, the Company changed its method of accounting for its payable to founding members under the tax receivable agreement (“TRA”), which requires the Company to pay 90% of the expected cash savings to NCM, Inc. from federal, state, and local jurisdictions upon realization of amortization and other deductions specified under the TRA. At inception of the TRA in 2007, the payable was recorded at fair value by discounting the amounts expected to be payable to founding members under the TRA at the Company’s weighted average cost of capital. The Company then remeasured the present value of the payable to founding members under the TRA each subsequent reporting period. As a result of the change in accounting principle, the payable is now stated at the undiscounted amount of all expected future payments under the agreement. The Company believes that the undiscounted presentation is preferable because it is consistent with the predominant accounting method used by other companies with such TRA agreements and is more consistent with the undiscounted approach used for the corresponding deferred tax assets that are subject to the TRA. Accordingly, the Condensed Consolidated Balance Sheets, Condensed Consolidated Statements of Income, Condensed Statements of Equity (Deficit) and Condensed Consolidated Statement of Cash Flows for the respective prior periods have been recast to reflect retrospective application of the change in accounting principle. Since this change in accounting principle dates back to the Company’s initial public offering ("IPO") in 2007, the Company has recorded the cumulative effect for the change in accounting principle to beginning retained earnings as of December 29, 2016. Additionally, subsequent to the issuance of the Company’s Consolidated Financial Statements for the year ended December 29, 2016 , the Company identified and corrected an immaterial non-cash error related to the accounting under ASC 740 for the Company’s payable to founding members under the TRA which was corrected within the Company’s Form 10-K for the period ending December 28, 2017 . As a result of the error, the liability under the TRA (including the historical discount on such payable) and related accounts for the year ended December 29, 2016 were restated from the amount previously reported to reflect the additional amounts that will be payable under the TRA upon settlement of all expected future payments to the founding members. Further, the deferred tax liability recorded at the IPO related to the discounted TRA liability was reversed to reflect all applicable basis differences related to the TRA. The impact of the error on the Condensed Consolidated Statements of Income for the three and six months ended June 29, 2017 is presented within the tables below and the impact of the error on the Condensed Consolidated Statement of Cash Flows and the Condensed Consolidated Statement of Equity for the six months ended June 29, 2017 is stated below. The Condensed Consolidated Financial Statements and corresponding footnotes for the three and six months ended June 29, 2017 have been restated from the amounts previously reported to reflect the correction of this error as shown within the tables below. The following table presents the effect of the change in accounting principle to the December 29, 2016 beginning retained earnings balance and additional paid in capital (deficit) ("APIC") balance (in millions): Beginning retained earnings (distributions in excess of earnings), as of December 29, 2016 – as previously reported $ (248.3 ) Cumulative effect for change in accounting principle $ 117.6 Beginning retained earnings (distributions in excess of earnings), as of December 29, 2016 – as adjusted $ (130.7 ) Beginning additional paid in capital (deficit), as of December 29, 2016 – as previously reported $ (110.5 ) Cumulative effect for change in accounting principle $ (233.1 ) Beginning additional paid in capital (deficit), as of December 29, 2016 – as adjusted $ (343.6 ) The following table presents the effects of the change in accounting principle to the Condensed Consolidated Balance Sheet (in millions): As of December 28, 2017 As Reported Change in Accounting Principle As Adjusted Long-term deferred tax assets, net of valuation allowance of $98.1 $ 161.0 $ 25.0 $ 186.0 TOTAL ASSETS 1,148.1 25.0 1,173.1 Long-term payable to founding members under tax receivable agreement 114.0 98.6 212.6 Total liabilities 1,149.3 98.6 1,247.9 Additional paid in capital (deficit) 13.8 (246.9 ) (233.1 ) Retained earnings (distributions in excess of earnings) (303.5 ) 173.3 (130.2 ) Total equity/(deficit) (1.2 ) (73.6 ) (74.8 ) TOTAL LIABILITIES AND EQUITY/DEFICIT 1,148.1 25.0 1,173.1 The following tables present the effects of the correction of the prior period error and change in accounting principle to the Condensed Consolidated Statement of Income (in millions, except for per share data): Three Months Ended June 29, 2017 As Reported Correction of an Error As Corrected Change in Accounting Principle As Corrected and Adjusted Accretion of interest on the discounted payable to founding members under tax receivable agreement $ 2.9 $ 1.4 $ 4.3 $ (4.3 ) $ — Gain on re-measurement of the payable to founding members under the tax receivable agreement $ — $ (5.5 ) $ (5.5 ) $ 4.9 $ (0.6 ) Total non-operating expenses $ 15.6 $ (4.1 ) $ 11.5 $ 0.6 $ 12.1 INCOME BEFORE INCOME TAXES $ 12.7 $ 4.1 $ 16.8 $ (0.6 ) $ 16.2 Income tax expense $ 1.8 $ 1.1 $ 2.9 $ (1.3 ) $ 1.6 CONSOLIDATED NET INCOME $ 10.9 $ 3.0 $ 13.9 $ 0.7 $ 14.6 NET INCOME ATTRIBUTABLE TO NCM, INC. $ 1.5 $ 3.0 $ 4.5 $ 0.7 $ 5.2 NET INCOME PER NCM, INC.

The change in accounting principle resulted in an increase of $14.5 million within the activity and a decrease of $218.7 million in the ending balance of the additional paid in capital (deficit) balance for the six months ended June 29, 2017 . These adjustments were within the ‘Income tax and other impacts of NCM LLC ownership changes’ line of the Condensed Consolidated Statements of Equity included herein. The change in accounting principle resulted in a $2.3 million and $4.4 million decrease in net income and a $0.03 and $0.06 decrease in net income per share for the three and six months ended June 28, 2018 .
