Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation	BASIS OF PRESENTATION In the opinion of management of The New York Times Company (the “Company”), the Condensed Consolidated Financial Statements present fairly the financial position of the Company as of September 30, 2018 , and December 31, 2017 , and the results of operations, changes in stockholder’s equity and cash flows of the Company for the periods ended September 30, 2018 , and September 24, 2017 . The Company and its consolidated subsidiaries are referred to collectively as “we,” “us” or “our.” All adjustments necessary for a fair presentation have been included and are of a normal and recurring nature. All significant intercompany accounts and transactions have been eliminated in consolidation. The financial statements were prepared in accordance with the requirements of the Securities and Exchange Commission (“SEC”) for interim reporting. As permitted under those rules, certain notes or other financial information that are normally required by accounting principles generally accepted in the United States of America (“GAAP”) have been condensed or omitted from these interim financial statements. These financial statements, therefore, should be read in conjunction with the Consolidated Financial Statements and related Notes included in our Annual Report on Form 10-K for the year ended December 31, 2017 . Due to the seasonal nature of our business, operating results for the interim periods are not necessarily indicative of a full year’s operations. The fiscal periods included herein comprise 13 weeks for the third quarter. The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the amounts reported in our Condensed Consolidated Financial Statements. Actual results could differ from these estimates.

Accounting Policies [Abstract]
Summary of Significant Accounting Policies	SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Except as described herein, as of September 30, 2018 , our significant accounting policies, which are detailed in our Annual Report on Form 10-K for the year ended December 31, 2017 , have not changed materially. Recently Adopted Accounting Pronouncements Accounting Standard Update(s) Topic Effective Period Summary 2018-05 Income Taxes (Topic 740) Upon issuance The Financial Accounting Standards Board (“FASB”) issued authoritative guidance that amends Accounting Standards Codification (“ASC”) Topic 740 “Income Taxes” to conform with SEC Staff Accounting Bulletin 118, issued in December 2017, which allowed SEC registrants to record provisional amounts for the year ended December 31, 2017, due to the complexities involved in accounting for the enactment of the 2017 Tax Cuts and Jobs Act (the “Tax Act”). During the nine months ended September 30, 2018, we did not record any measurement period adjustments to the provisional estimate recorded at December 31, 2017 for the Tax Act. The accounting for the impact of the Tax Act is expected to be completed by the fourth quarter of 2018. 2018-02 Income Statement—Reporting Comprehensive Income (Topic 220): Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income Fiscal years beginning after December 15, 2018, and interim periods within those fiscal years. Early adoption is permitted. The FASB issued authoritative guidance providing financial statement preparers with an option to reclassify stranded tax effects within accumulated other comprehensive income (“AOCI”) to retained earnings in each period in which the effect of the change in the U.S. federal corporate income tax rate related to the Tax Act is recorded. The Company elected to adopt this guidance to reclassify the stranded tax effects from AOCI to retained earnings in the first quarter of 2018. Our current accounting policy related to releasing tax effects from AOCI for pension and other postretirement benefits is a plan by plan approach. Accordingly, the Company recorded a $94.1 million cumulative effect adjustment for stranded tax effects, such as pension and other postretirement benefits, to “Retained earnings” on January 1, 2018. See Note 13 for more information. Accounting Standard Update(s) Topic Effective Period Summary 2017-07 Compensation—Retirement Benefits (Topic 715): Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost Fiscal years beginning after December 15, 2017, and interim periods within those fiscal years. Early adoption is permitted. The FASB issued authoritative guidance that requires the service cost component of net periodic benefit costs to be presented separately from the other components of net periodic benefit costs. Service cost will be presented with other employee compensation cost within “Operating costs.” The other components of net periodic benefit costs, such as interest cost, amortization of prior service cost and gains or losses, are required to be presented outside of operations. The guidance should be applied retrospectively for the presentation of the service cost component in the income statement and allows a practical expedient for the estimation basis for applying the retrospective presentation requirements. Since Accounting Standards Update (“ASU”) 2017-07 only requires change to the Condensed Consolidated Statements of Operations classification of the components of net periodic benefit cost, there are no changes to income from continuing operations or net income. As a result of the adoption of the ASU during the first quarter of 2018, the service cost component of net periodic benefit costs continues to be recognized in total operating costs and the other components of net periodic benefit costs have been reclassified to “Other components of net periodic benefit costs/(income)” in the Condensed Consolidated Statements of Operations below “Operating profit” on a retrospective basis. The Company reclassified $0.2 million and $1.0 million of credits from “Production costs” and “Selling and general and administrative costs,” respectively, to “Other components of net periodic benefit costs/(income)” in the third quarter of 2017 and $0.7 million and $2.9 million of credits from “Production costs” and “Selling and general and administrative costs,” respectively, to “Other components of net periodic benefit costs/(income)” in the first nine months of 2017. See Note 10 for the components of net periodic benefit costs/(income) for our pension and other postretirement benefits plans. 2016-18 Statement of Cash Flow: Restricted Cash Fiscal years beginning after December 15, 2017, and interim periods within those fiscal years. Early adoption is permitted. The FASB issued authoritative guidance that amends the guidance in ASC 230 on the classification and presentation of restricted cash in the statement of cash flows. The key requirements of the ASU are: (1) all entities should include in their cash and cash-equivalent balances in the statements of cash flows those amounts that are deemed to be restricted cash or restricted cash equivalents, (2) a reconciliation between the statement of financial position and the statement of cash flows must be disclosed when the statement of financial position includes more than one line item for cash, cash equivalents and restricted cash, (3) changes in restricted cash that result from transfers between cash, cash equivalents and restricted cash should not be presented as cash flow activities in the statement of cash flows and (4) an entity with a material balance of amounts generally described as restricted cash must disclose information about the nature of the restrictions. As a result of the adoption of ASU 2016-18 in the first quarter of 2018, the Company included the restricted cash balance with the cash and cash equivalents balances in the Condensed Consolidated Statements of Cash Flows on a retrospective basis. The reclassification did not have a material impact to the Condensed Consolidated Statement of Cash Flows for the first nine months of 2017. The Company has added a reconciliation from the Condensed Consolidated Balance Sheets to the Condensed Consolidated Statement of Cash Flows. See Note 8 for more information. Accounting Standard Update(s) Topic Effective Period Summary 2016-01 2018-03 Financial Instruments—Overall: Recognition and Measurement of Financial Assets and Financial Liabilities Fiscal years beginning after December 15, 2017, and interim periods within those fiscal years. The FASB issued authoritative guidance that addresses certain aspects of recognition, measurement, presentation and disclosure of financial instruments, including requirements to measure most equity investments at fair value with changes in fair value recognized in net income, to perform a qualitative assessment of equity investments without readily determinable fair values, and to separately present financial assets and liabilities by measurement category and by type of financial asset on the balance sheet or the accompanying notes to the financial statements. We adopted ASU 2016-01 in the first quarter of 2018 and elected the measurement alternative, defined as cost, less impairments, adjusted by observable price changes, given our equity instruments are without readily determinable fair values. This guidance did not impact our available-for-sale (“AFS”) securities because we only hold debt securities. We also early adopted ASU 2018-03 in the first quarter of 2018. The adoptions of ASU 2016-01 and ASU 2018-03 did not have a material effect on our Condensed Consolidated Financial Statements. See Note 6 for more information. 2014-09 2016-08 2016-10 2016-12 Revenue from Contracts with Customers (Topic 606) Fiscal years beginning after December 31, 2017 The FASB issued authoritative guidance that prescribes a single comprehensive model for entities to use in the accounting of revenue arising from contracts with customers. The new guidance supersedes virtually all existing revenue guidance under GAAP. There are two transition options available to entities: the full retrospective approach or the modified retrospective approach. On January 1, 2018, the Company adopted Topic 606. The Company has elected the modified retrospective approach, which allows for the new revenue standard to be applied to all existing contracts as of the effective date and a cumulative catch-up adjustment to be recorded to “Retained earnings.” The Company recognizes revenue under the core principle to depict the transfer of control to the Company’s customers in an amount reflecting the consideration to which the Company expects to be entitled. In order to achieve that core principle, the Company applies the following five-step approach: (1) identify the contract with a customer, (2) identify the performance obligations in the contract, (3) determine the transaction price, (4) allocate the transaction price to the performance obligations in the contract and (5) recognize revenue when a performance obligation is satisfied. The most significant change to the Company’s accounting practices related to accounting for certain licensing arrangements in the other revenue category for which archival and updated content is included. Under the former revenue guidance, licensing revenue was generally recognized over the term of the contract based on the annual minimum guarantee amount specified in the contractual agreement with the licensee. Based on the guidance of Topic 606, the Company has determined that the archival content and updated content included in these licensing arrangements represent two separate performance obligations. As such, a portion of the total contract consideration related to the archival content was recognized at the commencement of the contract when control of the archival content is transferred. The remaining contractual consideration will be recognized proportionately over the term of the contract when updated content is transferred to the licensee, in line with when the control of the new content is transferred. The net impact of these changes accelerated the revenue of contracts not completed as of January 1, 2018. In connection with the adoption of the standard the Company recorded a net increase to opening retained earnings of $2.6 million ($3.5 million before tax) and a contract asset of $3.5 million, with $1.3 million categorized as a current asset and $2.2 million categorized as a long term asset as of January 1, 2018. The impact to “Other revenues” as a result of applying Topic 606 will be a decrease of $1.3 million for the twelve months ended December 30, 2018. Our subscription and advertising revenues were not changed by the new guidance. See Note 3 for more information on our revenues and the application of Topic 606. Recently Issued and Not Yet Adopted Accounting Pronouncements Accounting Standard Update(s) Topic Effective Period Summary 2018-15 Intangibles—Goodwill and Other—Internal-Use Software Fiscal years beginning after December 15, 2019, and interim periods within those fiscal years. Early adoption is permitted. The FASB issued authoritative guidance that clarifies the accounting for implementation costs in cloud computing arrangements. The standard provides that implementation costs be evaluated for capitalization using the same criteria as that used for internal-use software development costs, with amortization expense being recorded in the same income statement expense line as the hosted service costs and over the expected term of the hosting arrangement. We are currently in the process of evaluating the impact of this guidance on our consolidated financial statements. 2018-14 Compensation—Retirement Benefits—Defined Benefit Plans—General Fiscal years beginning after December 15, 2020, and interim periods within those fiscal years. Early adoption is permitted. The FASB issued authoritative guidance that modifies the disclosure requirements for employers that sponsor defined benefit pension or other postretirement benefit plans. The guidance removes disclosures, clarifies the specific requirements of disclosures and adds disclosure requirements identified as relevant. We are currently in the process of evaluating the impact of this guidance on our consolidated financial statements. 2018-13 Fair Value Measurement (Topic 820) Disclosure Framework Fiscal years beginning after December 15, 2019, and interim periods within those fiscal years. Early adoption is permitted. The FASB issued authoritative guidance that modifies the disclosure requirements on fair value measurements. The amendments on changes in unrealized gains and losses, the range and weighted average of significant unobservable inputs used to develop Level 3 fair value measurements, and the narrative description of measurement uncertainty should be applied prospectively for only the most recent interim or annual period presented in the initial fiscal year of adoption. All other amendments should be applied retrospectively to all periods presented upon their effective date. We are currently in the process of evaluating the impact of this guidance on our consolidated financial statements. 2016-13 Financial Instruments—Credit Losses Fiscal years beginning after December 15, 2019, and interim periods within those fiscal years. Early adoption is permitted for fiscal years beginning after December 15, 2018, and interim periods within those fiscal years. The FASB issued authoritative guidance that amends guidance on reporting credit losses for assets, including trade receivables, available-for-sale marketable securities and any other financial assets not excluded from the scope that have the contractual right to receive cash. For trade receivables, ASU 2016-13 eliminates the probable initial recognition threshold in current generally accepted accounting standards, and, instead, requires an entity to reflect its current estimate of all expected credit losses. The allowance for credit losses is a valuation account that is deducted from the gross trade receivables balance to present the net amount expected to be collected. For available-for-sale marketable securities, credit losses should be measured in a manner similar to current generally accepted accounting standards; however, ASU 2016-13 will require that credit losses be presented as an allowance rather than as a write-down. Accounting Standard Update(s) Topic Effective Period Summary 2016-02 2018-10 2018-11 Leases Fiscal years beginning after December 30, 2018. Early adoption is permitted. The FASB issued authoritative guidance that provides guidance on accounting for leases and disclosure of key information about leasing arrangements. The guidance requires lessees to recognize the following for all operating and finance leases at the commencement date: (1) a lease liability, which is the obligation to make lease payments arising from a lease, measured on a discounted basis, and (2) a right-of-use asset representing the lessee’s right to use, or control the use of, the underlying asset for the lease term. A lessee is permitted to make an accounting policy election not to recognize lease assets and lease liabilities for short-term leases with a term of 12 months or less. The guidance does not fundamentally change lessor accounting; however, some changes have been made to align that guidance with the lessee guidance and other areas within GAAP. The Company expects to adopt this guidance in the first quarter of 2019 utilizing the alternative transition method. Upon adoption, the Company expects to elect the transition package of practical expedients permitted within the new standard, which, among other things, allows the carryforward of the historical lease classification and allows the Company to recognize a cumulative effect adjustment to the opening balance of retained earnings. The Company continues to evaluate which other, if any, practical expedients will be elected. The adoption of the standards will require us to add right-of-use assets and lease liabilities onto our balance sheet. Based on our lease portfolio at December 31, 2017, the right-of-use asset and lease liability would have been in the range of $40 million to $45 million on our Consolidated Balance Sheets based on the remaining lease payments, with no material impact to our Consolidated Statement of Operations or liquidity. However, the ultimate impact of adopting ASU 2016-02 will depend on the Company’s lease portfolio as of the adoption date. The Company considers the applicability and impact of all recently issued accounting pronouncements. Recent accounting pronouncements not specifically identified in our disclosures are either not applicable to the Company or are not expected to have a material effect on our financial condition or results of operations.

Revenue

Revenue from Contract with Customer [Abstract]
Revenue	REVENUE We generate revenues principally from subscriptions and advertising. Subscription revenues consist of revenues from subscriptions to our print and digital products (which include our news product, as well as our Crossword and Cooking products) and single-copy and bulk sales of our print products. Subscription revenues are based on both the number of copies of the printed newspaper sold and digital-only subscriptions, and the rates charged to the respective customers. Advertising revenues are derived from the sale of our advertising products and services on our print and digital platforms. These revenues are primarily determined by the volume, rate and mix of advertisements. Other revenues primarily consist of revenues from commercial printing, building rental income, news services/syndication, affiliate referrals (revenue generated by offering direct links to merchants in exchange for a portion of the sale price), digital archive licensing, NYT Live (our live events business) and retail commerce. Revenue is recognized when a performance obligation is satisfied by transferring a promised good or service to a customer. A good or service is considered transferred when the customer obtains control, which is when the customer has the ability to direct the use of and/or obtain substantially all of the benefits of an asset. Proceeds from subscription revenues are deferred at the time of sale and are recognized on a pro rata basis over the terms of the subscriptions. Payment is typically due upfront and the revenue is recognized ratably over the subscription period. The deferred proceeds are recorded within “Unexpired subscription revenue” in the Condensed Consolidated Balance Sheet. Single-copy revenue is recognized based on date of publication, net of provisions for related returns. Payment for single-copy sales is typically due upon complete satisfaction of our performance obligations. The Company does not have significant financing components or significant payment terms as we only offer industry standard payment terms to our customers. When our subscriptions are sold through third parties, we are a principal in the transaction and, therefore, revenues and related costs to third parties for these sales are reported on a gross basis. We are considered a principal if we control a promised good or service before transferring that good or service to the customer. The Company considers several factors to determine if it controls the good and therefore is the principal. These factors include: (1) if we have primary responsibility for fulfilling the promise, (2) if we have inventory risk before the goods or services are transferred to the customer or after the transfer of control to the customer and (3) if we have discretion in establishing price for the specified good or service. Advertising revenues are recognized when advertisements are published in newspapers or placed on digital platforms or, with respect to certain digital advertising, each time a user clicks on certain advertisements, net of provisions for estimated rebates and rate adjustments. We recognize a rebate obligation as a reduction of revenues based on the amount of estimated rebates that will be earned related to the underlying revenue transactions during the period. Measurement of the rebate obligation is estimated based on the historical experience of the number of customers that ultimately earn and use the rebate. We recognize a reserve for rate adjustments as a reduction of revenues based on the amount of estimated post-billing adjustments that will be claimed. Measurement of the rate adjustment reserve is estimated based on historical experience of credits actually issued. Payment for advertising is due upon complete satisfaction of our performance obligations. The Company has a formal credit checking policy, procedures and controls in place that evaluate collectability prior to ad publication. In instances where the timing of revenue recognition differs from the timing of invoicing, we have determined our contracts do not include a significant financing component. Subscription, advertising and other revenues were as follows: For the Quarters Ended For the Nine Months Ended (In thousands) September 30, 2018 September 24, 2017 September 30, 2018 September 24, 2017 Subscription $ 257,796 $ 246,638 $ 779,018 $ 739,050 Advertising 121,677 113,633 366,525 375,895 Other (1) 37,873 25,364 100,311 76,568 Total $ 417,346 $ 385,635 $ 1,245,854 $ 1,191,513 (1) Other revenue includes approximately $7 million and $5 million of building rental income for the third quarters of 2018 and 2017 , respectively, and approximately $17 million and $13 million for the first nine months of 2018 and 2017 , respectively, which is not under the scope of Topic 606. The following table summarizes digital-only subscription revenues, which are a component of subscription revenues above, for the third quarters and first nine months of 2018 and 2017 : For the Quarters Ended For the Nine Months Ended (In thousands) September 30, 2018 September 24, 2017 September 30, 2018 September 24, 2017 Digital-only subscription revenues: News product subscription revenues (1) $ 95,568 $ 82,073 $ 279,693 $ 234,234 Other product subscription revenues (2) 5,639 3,610 15,669 9,810 Total digital-only subscription revenues $ 101,207 $ 85,683 $ 295,362 $ 244,044 (1) Includes revenues from subscriptions to the Company’s news product. News product subscription packages that include access to the Company’s Crossword and Cooking products are also included in this category. (2) Includes revenues from standalone subscriptions to the Company’s Crossword and Cooking products.

For such arrangements, we allocate revenue to each performance obligation based on its relative standalone selling price. In the case of our licensing contracts, the transaction price was allocated among the performance obligations, (i) the archival content and (ii) the updated content, based on the Company’s estimate of the standalone selling price of each of the performance obligations, as they are currently not sold separately. As of September 30, 2018 , the aggregate amount of the transaction price allocated to the remaining performance obligations is approximately $25 million . The Company will recognize this revenue as control of the performance obligation is transferred to the customer. We expect that approximately $5 million , $10 million and $10 million will be recognized in the remainder of 2018, 2019 and 2020, respectively. Contract Assets We record revenue from performance obligations when performance obligations are satisfied. For our licensing revenue, we record revenue related to the portion of performance obligation (i) satisfied at the commencement of the contract when the customer obtains control of the archival content or (ii) when the updated content is transferred. We receive payments from customers based upon contractual billing schedules. As the transfer of control represents a right to the contract consideration, we record a contract asset in “Other current assets” for short-term contract assets and “Miscellaneous assets” for long-term contract assets on the Consolidated Balance Sheet for any amounts not yet invoiced to the customer. As of September 30, 2018 , the Company had $2.6 million in contract assets recorded in the Condensed Consolidated Balance Sheet. The contract asset is reclassified to “Accounts receivable” when the customer is invoiced based on the contractual billing schedule. The increase in the contract assets balance for the nine months ended September 30, 2018 , is primarily driven by the cumulative catch-up adjustment recorded by the Company on January 1, 2018, of $3.5 million as a result of adoption of Topic 606, offset by $0.9 million of consideration that was reclassified to “Accounts receivable” when invoiced based on the contractual billing schedules for the period ended September 30, 2018 . Significant Judgments Our contracts with customers sometimes include promises to transfer multiple products and services to a customer. Determining whether products and services are considered distinct performance obligations that should be accounted for separately versus together may require significant judgment. We use an observable price to determine the standalone selling price for separate performance obligations if available or, when not available, an estimate that maximizes the use of observable inputs and faithfully depicts the selling price of the promised goods or services if we sold those goods or services separately to a similar customer in similar circumstances. Practical Expedients and Exemptions We expense the cost to obtain or fulfill a contract as incurred because the amortization period of the asset that the entity otherwise would have recognized is one year or less. We also apply the practical expedient for the significant financing component when the difference between the payment and the transfer of the products and services is a year or less

We consider factors such as the duration, severity and the reason for the decline in value, the potential recovery period and whether we intend to sell. We also consider whether (i) it is more likely than not that we will be required to sell the debt securities before recovery of their amortized cost basis and (ii) the amortized cost basis cannot be recovered as a result of credit losses. As of September 30, 2018 , we did not intend to sell and it was not likely that we would be required to sell these investments before recovery of their amortized cost basis, which may be at maturity. Unrealized losses related to these investments are primarily due to interest rate fluctuations as opposed to changes in credit quality. Therefore, as of September 30, 2018 , we have recognized no OTTI loss. As of September 30, 2018 , our short-term and long-term marketable securities had remaining maturities of less than 1 month to 12 months and 13 months to 35 months , respectively. See Note 9 for more information regarding the fair value of our marketable securities.

Investments, Debt and Equity Securities [Abstract]
Investments	INVESTMENTS Equity Method Investments As of September 30, 2018 , our investments in joint ventures of $1.7 million consisted of a 40% equity ownership interest in Madison Paper Industries (“Madison”), a partnership that previously operated a supercalendered paper mill in Maine. The Company and UPM-Kymmene Corporation (“UPM”), a Finnish paper manufacturing company, are partners through subsidiary companies in Madison. The Company’s 40% ownership of Madison is through an 80% -owned consolidated subsidiary that owns 50% of Madison. UPM owns 60% of Madison, including a 10% interest through a 20% noncontrolling interest in the consolidated subsidiary of the Company. In 2016, the paper mill closed and we recognized a $41.4 million loss related to the closure. As a result of the mill closure, we wrote our investment down to zero . In the fourth quarter of 2016, Madison sold certain assets at the mill site and we recognized a $3.9 million gain related to the sale. In 2017, we recognized a $20.8 million gain, primarily related to the sale of the remaining assets (which primarily consisted of hydro power assets), partially offset by the loss related to Madison’s settlement of certain pension obligations. The partnership is currently in the process of liquidation. The investment is accounted for under the equity method, and is recorded in “Miscellaneous assets” in our Condensed Consolidated Balance Sheets. Our proportionate share of the operating results of our investment is recorded in “(Loss)/Gain from joint ventures” in our Condensed Consolidated Statements of Operations. The following table presents summarized income statement information for Madison, which follows a calendar year: For the Quarters Ended For the Nine Months Ended (In thousands) September 30, 2018 September 30, 2017 September 30, 2018 September 30, 2017 Revenues $ — $ — $ — $ — Expenses: Cost of sales — (105 ) — (1,277 ) General and administrative (expense)/income and other (65 ) 60,216 (99 ) 59,662 Total (expense)/income (65 ) 60,111 (99 ) 58,385 Operating (loss)/income (65 ) 60,111 (99 ) 58,385 Other income/(expense) 33 (1 ) 81 (7 ) Net (loss)/income $ (32 ) $ 60,110 $ (18 ) $ 58,378 We received no distributions from Madison during the third quarters and first nine months of 2018 and 2017 , respectively. Non-Marketable Equity Securities Our non-marketable equity securities are investments in privately held companies/funds without readily determinable market values. Prior to January 1, 2018 and the adoption of ASU 2016-01, we accounted for our non-marketable equity securities at cost less impairment. Subsequent to the adoption of ASU 2016-01 as of January 1, 2018, we elected the measurement alternative, defined as cost, less impairments, adjusted by observable price changes given our non-marketable equity securities are without readily determinable fair values. We estimate the fair value based on valuation methods using the observable transaction price at the transaction date. Realized gains and losses on non-marketable securities sold or impaired are recognized in “Interest expense and other, net.” Non-marketable equity securities are classified within Level 3 in the fair value hierarchy. See Note 9 for the definition of Level 3. As of September 30, 2018 and December 31, 2017 , non-marketable equity securities included in “Miscellaneous assets’’ in our Condensed Consolidated Balance Sheets had a carrying value of $14.6 million and $13.6 million , respectively. We did not have any material fair value adjustments in the third quarter and first nine months of 2018 .

Carey & Co. LLC of the Company’s intention to exercise its option under the Lease Agreement, dated March 6, 2009, by and between the parties (the “Lease”) to repurchase a portion of the Company’s leasehold condominium interest in the Company’s headquarters building located at 620 Eighth Avenue, New York, New York (the “Condo Interest”). The Lease was part of a transaction in 2009 under which the Company sold and simultaneously leased back approximately 750,000 rentable square feet, comprising the Condo Interest. The sale price for the Condo Interest was approximately $225 million . Under the Lease, the Company has an option exercisable in the second half of 2019 to repurchase the Condo Interest for approximately $250 million . The Company has accounted for the transaction as a financing transaction, and has continued to depreciate the Condo Interest and account for the rental payments as interest expense. The difference between the purchase option price and the net sale proceeds from the transaction is being amortized over the 10 -year period of 2009-2019 through interest expense.

Headquarters Redesign and Consolidation In December 2016, we announced plans to redesign our headquarters building, consolidate our space within a smaller number of floors and lease the additional floors to third parties. We incurred $2.5 million of total expenses related to these measures in the third quarter of 2017 , and $3.1 million and $6.9 million in the first nine months of 2018 and 2017 , respectively. We capitalized approximately $3 million and $26 million in the third quarters of 2018 and 2017 , respectively, and $14 million and $37 million in the first nine months of 2018 and 2017 , respectively, related to these measures.

The costs in 2017 were related to a workforce reduction primarily affecting our newsroom in connection with measures to streamline our editing process and allow for further investments in the newsroom. These costs are recorded in “Selling, general and administrative costs” in our Condensed Consolidated Statements of Operations. We had a severance liability of $8.3 million and $18.8 million included in “Accrued expenses and other” in our Condensed Consolidated Balance Sheets as of September 30, 2018 , and December 31, 2017 , respectively. We anticipate most of the payments will be made within the next twelve months.

Fair Value Disclosures [Abstract]
Fair Value Measurements	FAIR VALUE MEASUREMENTS Fair value is the price that would be received upon the sale of an asset or paid upon transfer of a liability in an orderly transaction between market participants at the measurement date. The transaction would be in the principal or most advantageous market for the asset or liability, based on assumptions that a market participant would use in pricing the asset or liability. The fair value hierarchy consists of three levels: Level 1–quoted prices in active markets for identical assets or liabilities that the reporting entity has the ability to access at the measurement date; Level 2–inputs other than quoted prices included within Level 1 that are observable for the asset or liability, either directly or indirectly; and Level 3–unobservable inputs for the asset or liability. Assets/Liabilities Measured and Recorded at Fair Value on a Recurring Basis The following table summarizes our financial assets and liabilities measured at fair value on a recurring basis as of September 30, 2018 , and December 31, 2017 : (In thousands) September 30, 2018 December 31, 2017 Total Level 1 Level 2 Level 3 Total Level 1 Level 2 Level 3 Assets: Short-term AFS securities (1) Corporate debt securities $ 138,635 $ — $ 138,635 $ — $ 150,107 $ — $ 150,107 $ — U.S. Treasury securities 112,784 — 112,784 — 70,951 — 70,951 — U.S. governmental agency securities 77,155 — 77,155 — 45,640 — 45,640 — Commercial paper 11,800 — 11,800 — 32,591 — 32,591 — Certificates of deposit 7,848 — 7,848 — 9,300 — 9,300 — Total short-term AFS securities $ 348,222 $ — $ 348,222 $ — $ 308,589 $ — $ 308,589 $ — Long-term AFS securities (1) Corporate debt securities $ 138,234 $ — $ 138,234 $ — $ 92,004 $ — $ 92,004 $ — U.S. Treasury securities 53,932 — 53,932 — 52,628 — 52,628 — U.S. governmental agency securities 47,889 — 47,889 — 96,779 — 96,779 — Total long-term AFS securities $ 240,055 $ — $ 240,055 $ — $ 241,411 $ — $ 241,411 $ — Liabilities: Deferred compensation (2) $ 25,817 $ 25,817 $ — $ — $ 29,526 $ 29,526 $ — $ — (1) Our marketable securities, which include U.S. Treasury securities, corporate debt securities, U.S. government agency securities, municipal securities, certificates of deposit and commercial paper, are recorded at fair value (see Note 4). We classified these investments as Level 2 since the fair value is based on market observable inputs for investments with similar terms and maturities. (2) The deferred compensation liability, included in “Other liabilities—other” in our Condensed Consolidated Balance Sheets, consists of deferrals under The New York Times Company Deferred Executive Compensation Plan (the “DEC”), which enables certain eligible executives to elect to defer a portion of their compensation on a pre-tax basis. The deferred amounts are invested at the executives’ option in various mutual funds. The fair value of deferred compensation is based on the mutual fund investments elected by the executives and on quoted prices in active markets for identical assets. Participation in the DEC was frozen effective December 31, 2015. Financial Instruments Disclosed, But Not Reported, at Fair Value The carrying value of our long-term debt was approximately $246 million as of September 30, 2018 , and approximately $243 million as of December 31, 2017 . The fair value of our long-term debt was approximately $266 million and $279 million as of September 30, 2018 , and December 31, 2017 , respectively. We estimate the fair value of our debt utilizing market quotations for debt that have quoted prices in active markets. Since our debt does not trade on a daily basis in an active market, the fair value estimates are based on market observable inputs based on borrowing rates currently available for debt with similar terms and average maturities (Level 2).

This group of participants was the last group under the RAP to have their benefit accruals frozen. As a result, we recorded a curtailment of $2.6 million in 2018. During the first nine months of 2018 and 2017 , we made pension contributions of $6.2 million and $5.9 million , respectively, to certain qualified pension plans. We expect contributions in 2018 to total approximately $8 million to satisfy funding requirements. Multiemployer Plans During the third quarter of 2018, we recorded a gain of $4.9 million from a pension liability adjustment, which was recorded in “Gain from pension liability adjustment” in our Condensed Consolidated Statements of Operations.

Income Tax Disclosure [Abstract]
Income Taxes	INCOME TAXES The Company had income tax expense of $10.1 million and $25.3 million in the third quarter and first nine months of 2018 , respectively. The Company had income tax expense of $23.4 million and $40.9 million in the third quarter and first nine months of 2017 , respectively. The decrease in income tax expense in the third quarter of 2018 compared to the same period in the prior year was primarily due to taxes incurred for a gain related to a joint venture in the third quarter of 2017 and the reduction in the U.S. federal corporate income tax rate, which took effect in 2018. The decrease in income tax expense in the first nine months of 2018 compared with the same period in the prior year was largely due to the reduction in the U.S. federal corporate income tax rate, which took effect in 2018 . The Company’s effective tax rates from continuing operations were 28.8% and 26.4% for the third quarter and first nine months of 2018 , respectively. The Company’s effective tax rates from continuing operations were 39.1% and 38.5% for the third quarter and first nine months of 2017 , respectively. The decrease in the effective tax rate in the third quarter of 2018 and the first nine months of 2018 compared with the same periods in the prior year was largely due to the reduction in the U.S. federal corporate income tax rate, which took effect in 2018 .

Earnings Per Share

Earnings Per Share [Abstract]
Earnings Per Share	EARNINGS PER SHARE We compute earnings per share using a two-class method, an earnings allocation method used when a company’s capital structure includes either two or more classes of common stock or common stock and participating securities. This method determines earnings per share based on dividends declared on common stock and participating securities (i.e., distributed earnings), as well as participation rights of participating securities in any undistributed earnings. Earnings per share is computed using both basic shares and diluted shares. The difference between basic and diluted shares is that diluted shares include the dilutive effect of the assumed exercise of outstanding securities. Our stock options, stock-settled long-term performance awards and restricted stock units could have a significant impact on diluted shares. Securities that could potentially be dilutive are excluded from the computation of diluted earnings per share when a loss from continuing operations exists or when the exercise price exceeds the market value of our Class A Common Stock, because their inclusion would result in an anti-dilutive effect on per share amounts. There were no anti-dilutive stock options, stock-settled long-term performance awards or restricted stock units excluded from the computation of diluted earnings per share in the third quarter and first nine months of 2018 . There were approximately 2 million stock options excluded from the computation of diluted earnings per share because they were anti-dilutive in the third quarter and first nine months of 2017 , respectively. There were no anti-dilutive restricted stock units or stock-settled long-term incentive compensation awards excluded from the computation of diluted earnings per share in the third quarter and first nine months of 2017 .

Commitments and Contingencies Disclosure [Abstract]
Contingent Liabilities	CONTINGENT LIABILITIES Newspaper and Mail Deliverers–Publishers’ Pension Fund In September 2013, the Newspaper and Mail Deliverers-Publishers’ Pension Fund (the “NMDU Fund”) assessed a partial withdrawal liability against the Company in the gross amount of approximately $26 million for the plan years ending May 31, 2012, and 2013 (the “Initial Assessment”), an amount that was increased to a gross amount of approximately $34 million in December 2014, when the NMDU Fund issued a revised partial withdrawal liability assessment for the plan year ending May 31, 2013 (the “Revised Assessment”). The NMDU Fund claimed that when City & Suburban Delivery Systems, Inc., a retail and newsstand distribution subsidiary of the Company and the largest contributor to the NMDU Fund, ceased operations in 2009, it triggered a decline of more than 70% in contribution base units in each of these two plan years. The Company disagreed with both the NMDU Fund’s determination that a partial withdrawal occurred and the methodology by which it calculated the withdrawal liability, and the parties engaged in arbitration proceedings to resolve the matter. In June 2016, the arbitrator issued an interim award and opinion that supported the NMDU Fund’s determination that a partial withdrawal had occurred, and concluded that the methodology used to calculate the Initial Assessment was correct. However, the arbitrator also concluded that the NMDU Fund’s calculation of the Revised Assessment was incorrect. In July 2017, the arbitrator issued a final award and opinion reflecting the same conclusions, which both the Company and NMDU Fund challenged in federal district court. In March 2018, the court determined that a partial withdrawal had occurred, but supported the Company’s position that the NMDU Fund’s calculation of the withdrawal liability was improper. The Company has appealed the court’s decision with respect to the determination that a partial withdrawal had occurred, and the NMDU Fund has appealed the court’s decision with respect to the calculation of the withdrawal liability. Due to requirements of the Employee Retirement Income Security Act of 1974 that sponsors make payments demanded by plans during arbitration and any resultant appeals, the Company had been making payments to the NMDU fund since September 2013 relating to the Initial Assessment and February 2015 relating to the Revised Assessment based on the NMDU Fund’s demand. As a result, as of September 30, 2018 , we have paid $18.0 million relating to the Initial Assessment since the receipt of the initial demand letter. We also paid $5.0 million related to the Revised Assessment, which was refunded in July 2016 based on the arbitrator’s ruling. The Company had a liability of $4.0 million as of September 30, 2018 , related to this matter. Management believes it is reasonably possible that the total loss in this matter could exceed the liability established by a range of zero to approximately $10 million . Other We are involved in various legal actions incidental to our business that are now pending against us. These actions are generally for amounts greatly in excess of the payments, if any, that may be required to be made. Although the Company cannot predict the outcome of these matters, it is possible that an unfavorable outcome in one or more matters could be material to the Company’s consolidated results of operations or cash flows for an individual reporting period. However, based on currently available information, management does not believe that the ultimate resolution of these matters, individually or in the aggregate, is likely to have a material effect on the Company’s financial position. Letters of Credit Commitment We have issued letters of credit totaling $56.2 million and $56.0 million a s of September 30, 2018 , and December 31, 2017 , respectively, in connection with a sub-lease entered into in the fourth quarter of 2017 for approximately four floors of our headquarters building, as well as a sub-lease entered into in the second quarter of 2018 for a portion of an additional floor. A portion of the letters of credit will expire pro rata through the second quarter of 2019, while a substantial amount of the remaining portion of the letters of credit will expire upon the Company’s repurchase of the Condo Interest in our headquarters building in 2019. Approximately $68 million and $63 million of marketable securities were used as collateral for the letters of credit, as of September 30, 2018 , and December 31, 2017 , respectively.

Accounting Policies [Abstract]
Recent Accounting Pronouncements	Recently Adopted Accounting Pronouncements Accounting Standard Update(s) Topic Effective Period Summary 2018-05 Income Taxes (Topic 740) Upon issuance The Financial Accounting Standards Board (“FASB”) issued authoritative guidance that amends Accounting Standards Codification (“ASC”) Topic 740 “Income Taxes” to conform with SEC Staff Accounting Bulletin 118, issued in December 2017, which allowed SEC registrants to record provisional amounts for the year ended December 31, 2017, due to the complexities involved in accounting for the enactment of the 2017 Tax Cuts and Jobs Act (the “Tax Act”). During the nine months ended September 30, 2018, we did not record any measurement period adjustments to the provisional estimate recorded at December 31, 2017 for the Tax Act. The accounting for the impact of the Tax Act is expected to be completed by the fourth quarter of 2018. 2018-02 Income Statement—Reporting Comprehensive Income (Topic 220): Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income Fiscal years beginning after December 15, 2018, and interim periods within those fiscal years. Early adoption is permitted. The FASB issued authoritative guidance providing financial statement preparers with an option to reclassify stranded tax effects within accumulated other comprehensive income (“AOCI”) to retained earnings in each period in which the effect of the change in the U.S. federal corporate income tax rate related to the Tax Act is recorded. The Company elected to adopt this guidance to reclassify the stranded tax effects from AOCI to retained earnings in the first quarter of 2018. Our current accounting policy related to releasing tax effects from AOCI for pension and other postretirement benefits is a plan by plan approach. Accordingly, the Company recorded a $94.1 million cumulative effect adjustment for stranded tax effects, such as pension and other postretirement benefits, to “Retained earnings” on January 1, 2018. See Note 13 for more information. Accounting Standard Update(s) Topic Effective Period Summary 2017-07 Compensation—Retirement Benefits (Topic 715): Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost Fiscal years beginning after December 15, 2017, and interim periods within those fiscal years. Early adoption is permitted. The FASB issued authoritative guidance that requires the service cost component of net periodic benefit costs to be presented separately from the other components of net periodic benefit costs. Service cost will be presented with other employee compensation cost within “Operating costs.” The other components of net periodic benefit costs, such as interest cost, amortization of prior service cost and gains or losses, are required to be presented outside of operations. The guidance should be applied retrospectively for the presentation of the service cost component in the income statement and allows a practical expedient for the estimation basis for applying the retrospective presentation requirements. Since Accounting Standards Update (“ASU”) 2017-07 only requires change to the Condensed Consolidated Statements of Operations classification of the components of net periodic benefit cost, there are no changes to income from continuing operations or net income. As a result of the adoption of the ASU during the first quarter of 2018, the service cost component of net periodic benefit costs continues to be recognized in total operating costs and the other components of net periodic benefit costs have been reclassified to “Other components of net periodic benefit costs/(income)” in the Condensed Consolidated Statements of Operations below “Operating profit” on a retrospective basis. The Company reclassified $0.2 million and $1.0 million of credits from “Production costs” and “Selling and general and administrative costs,” respectively, to “Other components of net periodic benefit costs/(income)” in the third quarter of 2017 and $0.7 million and $2.9 million of credits from “Production costs” and “Selling and general and administrative costs,” respectively, to “Other components of net periodic benefit costs/(income)” in the first nine months of 2017. See Note 10 for the components of net periodic benefit costs/(income) for our pension and other postretirement benefits plans. 2016-18 Statement of Cash Flow: Restricted Cash Fiscal years beginning after December 15, 2017, and interim periods within those fiscal years. Early adoption is permitted. The FASB issued authoritative guidance that amends the guidance in ASC 230 on the classification and presentation of restricted cash in the statement of cash flows. The key requirements of the ASU are: (1) all entities should include in their cash and cash-equivalent balances in the statements of cash flows those amounts that are deemed to be restricted cash or restricted cash equivalents, (2) a reconciliation between the statement of financial position and the statement of cash flows must be disclosed when the statement of financial position includes more than one line item for cash, cash equivalents and restricted cash, (3) changes in restricted cash that result from transfers between cash, cash equivalents and restricted cash should not be presented as cash flow activities in the statement of cash flows and (4) an entity with a material balance of amounts generally described as restricted cash must disclose information about the nature of the restrictions. As a result of the adoption of ASU 2016-18 in the first quarter of 2018, the Company included the restricted cash balance with the cash and cash equivalents balances in the Condensed Consolidated Statements of Cash Flows on a retrospective basis. The reclassification did not have a material impact to the Condensed Consolidated Statement of Cash Flows for the first nine months of 2017. The Company has added a reconciliation from the Condensed Consolidated Balance Sheets to the Condensed Consolidated Statement of Cash Flows. See Note 8 for more information. Accounting Standard Update(s) Topic Effective Period Summary 2016-01 2018-03 Financial Instruments—Overall: Recognition and Measurement of Financial Assets and Financial Liabilities Fiscal years beginning after December 15, 2017, and interim periods within those fiscal years. The FASB issued authoritative guidance that addresses certain aspects of recognition, measurement, presentation and disclosure of financial instruments, including requirements to measure most equity investments at fair value with changes in fair value recognized in net income, to perform a qualitative assessment of equity investments without readily determinable fair values, and to separately present financial assets and liabilities by measurement category and by type of financial asset on the balance sheet or the accompanying notes to the financial statements. We adopted ASU 2016-01 in the first quarter of 2018 and elected the measurement alternative, defined as cost, less impairments, adjusted by observable price changes, given our equity instruments are without readily determinable fair values. This guidance did not impact our available-for-sale (“AFS”) securities because we only hold debt securities. We also early adopted ASU 2018-03 in the first quarter of 2018. The adoptions of ASU 2016-01 and ASU 2018-03 did not have a material effect on our Condensed Consolidated Financial Statements. See Note 6 for more information. 2014-09 2016-08 2016-10 2016-12 Revenue from Contracts with Customers (Topic 606) Fiscal years beginning after December 31, 2017 The FASB issued authoritative guidance that prescribes a single comprehensive model for entities to use in the accounting of revenue arising from contracts with customers. The new guidance supersedes virtually all existing revenue guidance under GAAP. There are two transition options available to entities: the full retrospective approach or the modified retrospective approach. On January 1, 2018, the Company adopted Topic 606. The Company has elected the modified retrospective approach, which allows for the new revenue standard to be applied to all existing contracts as of the effective date and a cumulative catch-up adjustment to be recorded to “Retained earnings.” The Company recognizes revenue under the core principle to depict the transfer of control to the Company’s customers in an amount reflecting the consideration to which the Company expects to be entitled. In order to achieve that core principle, the Company applies the following five-step approach: (1) identify the contract with a customer, (2) identify the performance obligations in the contract, (3) determine the transaction price, (4) allocate the transaction price to the performance obligations in the contract and (5) recognize revenue when a performance obligation is satisfied. The most significant change to the Company’s accounting practices related to accounting for certain licensing arrangements in the other revenue category for which archival and updated content is included. Under the former revenue guidance, licensing revenue was generally recognized over the term of the contract based on the annual minimum guarantee amount specified in the contractual agreement with the licensee. Based on the guidance of Topic 606, the Company has determined that the archival content and updated content included in these licensing arrangements represent two separate performance obligations. As such, a portion of the total contract consideration related to the archival content was recognized at the commencement of the contract when control of the archival content is transferred. The remaining contractual consideration will be recognized proportionately over the term of the contract when updated content is transferred to the licensee, in line with when the control of the new content is transferred. The net impact of these changes accelerated the revenue of contracts not completed as of January 1, 2018. In connection with the adoption of the standard the Company recorded a net increase to opening retained earnings of $2.6 million ($3.5 million before tax) and a contract asset of $3.5 million, with $1.3 million categorized as a current asset and $2.2 million categorized as a long term asset as of January 1, 2018. The impact to “Other revenues” as a result of applying Topic 606 will be a decrease of $1.3 million for the twelve months ended December 30, 2018. Our subscription and advertising revenues were not changed by the new guidance. See Note 3 for more information on our revenues and the application of Topic 606. Recently Issued and Not Yet Adopted Accounting Pronouncements Accounting Standard Update(s) Topic Effective Period Summary 2018-15 Intangibles—Goodwill and Other—Internal-Use Software Fiscal years beginning after December 15, 2019, and interim periods within those fiscal years. Early adoption is permitted. The FASB issued authoritative guidance that clarifies the accounting for implementation costs in cloud computing arrangements. The standard provides that implementation costs be evaluated for capitalization using the same criteria as that used for internal-use software development costs, with amortization expense being recorded in the same income statement expense line as the hosted service costs and over the expected term of the hosting arrangement. We are currently in the process of evaluating the impact of this guidance on our consolidated financial statements. 2018-14 Compensation—Retirement Benefits—Defined Benefit Plans—General Fiscal years beginning after December 15, 2020, and interim periods within those fiscal years. Early adoption is permitted. The FASB issued authoritative guidance that modifies the disclosure requirements for employers that sponsor defined benefit pension or other postretirement benefit plans. The guidance removes disclosures, clarifies the specific requirements of disclosures and adds disclosure requirements identified as relevant. We are currently in the process of evaluating the impact of this guidance on our consolidated financial statements. 2018-13 Fair Value Measurement (Topic 820) Disclosure Framework Fiscal years beginning after December 15, 2019, and interim periods within those fiscal years. Early adoption is permitted. The FASB issued authoritative guidance that modifies the disclosure requirements on fair value measurements. The amendments on changes in unrealized gains and losses, the range and weighted average of significant unobservable inputs used to develop Level 3 fair value measurements, and the narrative description of measurement uncertainty should be applied prospectively for only the most recent interim or annual period presented in the initial fiscal year of adoption. All other amendments should be applied retrospectively to all periods presented upon their effective date. We are currently in the process of evaluating the impact of this guidance on our consolidated financial statements. 2016-13 Financial Instruments—Credit Losses Fiscal years beginning after December 15, 2019, and interim periods within those fiscal years. Early adoption is permitted for fiscal years beginning after December 15, 2018, and interim periods within those fiscal years. The FASB issued authoritative guidance that amends guidance on reporting credit losses for assets, including trade receivables, available-for-sale marketable securities and any other financial assets not excluded from the scope that have the contractual right to receive cash. For trade receivables, ASU 2016-13 eliminates the probable initial recognition threshold in current generally accepted accounting standards, and, instead, requires an entity to reflect its current estimate of all expected credit losses. The allowance for credit losses is a valuation account that is deducted from the gross trade receivables balance to present the net amount expected to be collected. For available-for-sale marketable securities, credit losses should be measured in a manner similar to current generally accepted accounting standards; however, ASU 2016-13 will require that credit losses be presented as an allowance rather than as a write-down. Accounting Standard Update(s) Topic Effective Period Summary 2016-02 2018-10 2018-11 Leases Fiscal years beginning after December 30, 2018. Early adoption is permitted. The FASB issued authoritative guidance that provides guidance on accounting for leases and disclosure of key information about leasing arrangements. The guidance requires lessees to recognize the following for all operating and finance leases at the commencement date: (1) a lease liability, which is the obligation to make lease payments arising from a lease, measured on a discounted basis, and (2) a right-of-use asset representing the lessee’s right to use, or control the use of, the underlying asset for the lease term. A lessee is permitted to make an accounting policy election not to recognize lease assets and lease liabilities for short-term leases with a term of 12 months or less. The guidance does not fundamentally change lessor accounting; however, some changes have been made to align that guidance with the lessee guidance and other areas within GAAP. The Company expects to adopt this guidance in the first quarter of 2019 utilizing the alternative transition method. Upon adoption, the Company expects to elect the transition package of practical expedients permitted within the new standard, which, among other things, allows the carryforward of the historical lease classification and allows the Company to recognize a cumulative effect adjustment to the opening balance of retained earnings. The Company continues to evaluate which other, if any, practical expedients will be elected. The adoption of the standards will require us to add right-of-use assets and lease liabilities onto our balance sheet. Based on our lease portfolio at December 31, 2017, the right-of-use asset and lease liability would have been in the range of $40 million to $45 million on our Consolidated Balance Sheets based on the remaining lease payments, with no material impact to our Consolidated Statement of Operations or liquidity. However, the ultimate impact of adopting ASU 2016-02 will depend on the Company’s lease portfolio as of the adoption date.

Accounting Policies [Abstract]
Schedule of Recently Adopted Accounting Pronouncements	Recently Adopted Accounting Pronouncements Accounting Standard Update(s) Topic Effective Period Summary 2018-05 Income Taxes (Topic 740) Upon issuance The Financial Accounting Standards Board (“FASB”) issued authoritative guidance that amends Accounting Standards Codification (“ASC”) Topic 740 “Income Taxes” to conform with SEC Staff Accounting Bulletin 118, issued in December 2017, which allowed SEC registrants to record provisional amounts for the year ended December 31, 2017, due to the complexities involved in accounting for the enactment of the 2017 Tax Cuts and Jobs Act (the “Tax Act”). During the nine months ended September 30, 2018, we did not record any measurement period adjustments to the provisional estimate recorded at December 31, 2017 for the Tax Act. The accounting for the impact of the Tax Act is expected to be completed by the fourth quarter of 2018. 2018-02 Income Statement—Reporting Comprehensive Income (Topic 220): Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income Fiscal years beginning after December 15, 2018, and interim periods within those fiscal years. Early adoption is permitted. The FASB issued authoritative guidance providing financial statement preparers with an option to reclassify stranded tax effects within accumulated other comprehensive income (“AOCI”) to retained earnings in each period in which the effect of the change in the U.S. federal corporate income tax rate related to the Tax Act is recorded. The Company elected to adopt this guidance to reclassify the stranded tax effects from AOCI to retained earnings in the first quarter of 2018. Our current accounting policy related to releasing tax effects from AOCI for pension and other postretirement benefits is a plan by plan approach. Accordingly, the Company recorded a $94.1 million cumulative effect adjustment for stranded tax effects, such as pension and other postretirement benefits, to “Retained earnings” on January 1, 2018. See Note 13 for more information. Accounting Standard Update(s) Topic Effective Period Summary 2017-07 Compensation—Retirement Benefits (Topic 715): Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost Fiscal years beginning after December 15, 2017, and interim periods within those fiscal years. Early adoption is permitted. The FASB issued authoritative guidance that requires the service cost component of net periodic benefit costs to be presented separately from the other components of net periodic benefit costs. Service cost will be presented with other employee compensation cost within “Operating costs.” The other components of net periodic benefit costs, such as interest cost, amortization of prior service cost and gains or losses, are required to be presented outside of operations. The guidance should be applied retrospectively for the presentation of the service cost component in the income statement and allows a practical expedient for the estimation basis for applying the retrospective presentation requirements. Since Accounting Standards Update (“ASU”) 2017-07 only requires change to the Condensed Consolidated Statements of Operations classification of the components of net periodic benefit cost, there are no changes to income from continuing operations or net income. As a result of the adoption of the ASU during the first quarter of 2018, the service cost component of net periodic benefit costs continues to be recognized in total operating costs and the other components of net periodic benefit costs have been reclassified to “Other components of net periodic benefit costs/(income)” in the Condensed Consolidated Statements of Operations below “Operating profit” on a retrospective basis. The Company reclassified $0.2 million and $1.0 million of credits from “Production costs” and “Selling and general and administrative costs,” respectively, to “Other components of net periodic benefit costs/(income)” in the third quarter of 2017 and $0.7 million and $2.9 million of credits from “Production costs” and “Selling and general and administrative costs,” respectively, to “Other components of net periodic benefit costs/(income)” in the first nine months of 2017. See Note 10 for the components of net periodic benefit costs/(income) for our pension and other postretirement benefits plans. 2016-18 Statement of Cash Flow: Restricted Cash Fiscal years beginning after December 15, 2017, and interim periods within those fiscal years. Early adoption is permitted. The FASB issued authoritative guidance that amends the guidance in ASC 230 on the classification and presentation of restricted cash in the statement of cash flows. The key requirements of the ASU are: (1) all entities should include in their cash and cash-equivalent balances in the statements of cash flows those amounts that are deemed to be restricted cash or restricted cash equivalents, (2) a reconciliation between the statement of financial position and the statement of cash flows must be disclosed when the statement of financial position includes more than one line item for cash, cash equivalents and restricted cash, (3) changes in restricted cash that result from transfers between cash, cash equivalents and restricted cash should not be presented as cash flow activities in the statement of cash flows and (4) an entity with a material balance of amounts generally described as restricted cash must disclose information about the nature of the restrictions. As a result of the adoption of ASU 2016-18 in the first quarter of 2018, the Company included the restricted cash balance with the cash and cash equivalents balances in the Condensed Consolidated Statements of Cash Flows on a retrospective basis. The reclassification did not have a material impact to the Condensed Consolidated Statement of Cash Flows for the first nine months of 2017. The Company has added a reconciliation from the Condensed Consolidated Balance Sheets to the Condensed Consolidated Statement of Cash Flows. See Note 8 for more information. Accounting Standard Update(s) Topic Effective Period Summary 2016-01 2018-03 Financial Instruments—Overall: Recognition and Measurement of Financial Assets and Financial Liabilities Fiscal years beginning after December 15, 2017, and interim periods within those fiscal years. The FASB issued authoritative guidance that addresses certain aspects of recognition, measurement, presentation and disclosure of financial instruments, including requirements to measure most equity investments at fair value with changes in fair value recognized in net income, to perform a qualitative assessment of equity investments without readily determinable fair values, and to separately present financial assets and liabilities by measurement category and by type of financial asset on the balance sheet or the accompanying notes to the financial statements. We adopted ASU 2016-01 in the first quarter of 2018 and elected the measurement alternative, defined as cost, less impairments, adjusted by observable price changes, given our equity instruments are without readily determinable fair values. This guidance did not impact our available-for-sale (“AFS”) securities because we only hold debt securities. We also early adopted ASU 2018-03 in the first quarter of 2018. The adoptions of ASU 2016-01 and ASU 2018-03 did not have a material effect on our Condensed Consolidated Financial Statements. See Note 6 for more information. 2014-09 2016-08 2016-10 2016-12 Revenue from Contracts with Customers (Topic 606) Fiscal years beginning after December 31, 2017 The FASB issued authoritative guidance that prescribes a single comprehensive model for entities to use in the accounting of revenue arising from contracts with customers. The new guidance supersedes virtually all existing revenue guidance under GAAP. There are two transition options available to entities: the full retrospective approach or the modified retrospective approach. On January 1, 2018, the Company adopted Topic 606. The Company has elected the modified retrospective approach, which allows for the new revenue standard to be applied to all existing contracts as of the effective date and a cumulative catch-up adjustment to be recorded to “Retained earnings.” The Company recognizes revenue under the core principle to depict the transfer of control to the Company’s customers in an amount reflecting the consideration to which the Company expects to be entitled. In order to achieve that core principle, the Company applies the following five-step approach: (1) identify the contract with a customer, (2) identify the performance obligations in the contract, (3) determine the transaction price, (4) allocate the transaction price to the performance obligations in the contract and (5) recognize revenue when a performance obligation is satisfied. The most significant change to the Company’s accounting practices related to accounting for certain licensing arrangements in the other revenue category for which archival and updated content is included. Under the former revenue guidance, licensing revenue was generally recognized over the term of the contract based on the annual minimum guarantee amount specified in the contractual agreement with the licensee. Based on the guidance of Topic 606, the Company has determined that the archival content and updated content included in these licensing arrangements represent two separate performance obligations. As such, a portion of the total contract consideration related to the archival content was recognized at the commencement of the contract when control of the archival content is transferred. The remaining contractual consideration will be recognized proportionately over the term of the contract when updated content is transferred to the licensee, in line with when the control of the new content is transferred. The net impact of these changes accelerated the revenue of contracts not completed as of January 1, 2018. In connection with the adoption of the standard the Company recorded a net increase to opening retained earnings of $2.6 million ($3.5 million before tax) and a contract asset of $3.5 million, with $1.3 million categorized as a current asset and $2.2 million categorized as a long term asset as of January 1, 2018. The impact to “Other revenues” as a result of applying Topic 606 will be a decrease of $1.3 million for the twelve months ended December 30, 2018. Our subscription and advertising revenues were not changed by the new guidance. See Note 3 for more information on our revenues and the application of Topic 606. Recently Issued and Not Yet Adopted Accounting Pronouncements Accounting Standard Update(s) Topic Effective Period Summary 2018-15 Intangibles—Goodwill and Other—Internal-Use Software Fiscal years beginning after December 15, 2019, and interim periods within those fiscal years. Early adoption is permitted. The FASB issued authoritative guidance that clarifies the accounting for implementation costs in cloud computing arrangements. The standard provides that implementation costs be evaluated for capitalization using the same criteria as that used for internal-use software development costs, with amortization expense being recorded in the same income statement expense line as the hosted service costs and over the expected term of the hosting arrangement. We are currently in the process of evaluating the impact of this guidance on our consolidated financial statements. 2018-14 Compensation—Retirement Benefits—Defined Benefit Plans—General Fiscal years beginning after December 15, 2020, and interim periods within those fiscal years. Early adoption is permitted. The FASB issued authoritative guidance that modifies the disclosure requirements for employers that sponsor defined benefit pension or other postretirement benefit plans. The guidance removes disclosures, clarifies the specific requirements of disclosures and adds disclosure requirements identified as relevant. We are currently in the process of evaluating the impact of this guidance on our consolidated financial statements. 2018-13 Fair Value Measurement (Topic 820) Disclosure Framework Fiscal years beginning after December 15, 2019, and interim periods within those fiscal years. Early adoption is permitted. The FASB issued authoritative guidance that modifies the disclosure requirements on fair value measurements. The amendments on changes in unrealized gains and losses, the range and weighted average of significant unobservable inputs used to develop Level 3 fair value measurements, and the narrative description of measurement uncertainty should be applied prospectively for only the most recent interim or annual period presented in the initial fiscal year of adoption. All other amendments should be applied retrospectively to all periods presented upon their effective date. We are currently in the process of evaluating the impact of this guidance on our consolidated financial statements. 2016-13 Financial Instruments—Credit Losses Fiscal years beginning after December 15, 2019, and interim periods within those fiscal years. Early adoption is permitted for fiscal years beginning after December 15, 2018, and interim periods within those fiscal years. The FASB issued authoritative guidance that amends guidance on reporting credit losses for assets, including trade receivables, available-for-sale marketable securities and any other financial assets not excluded from the scope that have the contractual right to receive cash. For trade receivables, ASU 2016-13 eliminates the probable initial recognition threshold in current generally accepted accounting standards, and, instead, requires an entity to reflect its current estimate of all expected credit losses. The allowance for credit losses is a valuation account that is deducted from the gross trade receivables balance to present the net amount expected to be collected. For available-for-sale marketable securities, credit losses should be measured in a manner similar to current generally accepted accounting standards; however, ASU 2016-13 will require that credit losses be presented as an allowance rather than as a write-down. Accounting Standard Update(s) Topic Effective Period Summary 2016-02 2018-10 2018-11 Leases Fiscal years beginning after December 30, 2018. Early adoption is permitted. The FASB issued authoritative guidance that provides guidance on accounting for leases and disclosure of key information about leasing arrangements. The guidance requires lessees to recognize the following for all operating and finance leases at the commencement date: (1) a lease liability, which is the obligation to make lease payments arising from a lease, measured on a discounted basis, and (2) a right-of-use asset representing the lessee’s right to use, or control the use of, the underlying asset for the lease term. A lessee is permitted to make an accounting policy election not to recognize lease assets and lease liabilities for short-term leases with a term of 12 months or less. The guidance does not fundamentally change lessor accounting; however, some changes have been made to align that guidance with the lessee guidance and other areas within GAAP. The Company expects to adopt this guidance in the first quarter of 2019 utilizing the alternative transition method. Upon adoption, the Company expects to elect the transition package of practical expedients permitted within the new standard, which, among other things, allows the carryforward of the historical lease classification and allows the Company to recognize a cumulative effect adjustment to the opening balance of retained earnings. The Company continues to evaluate which other, if any, practical expedients will be elected. The adoption of the standards will require us to add right-of-use assets and lease liabilities onto our balance sheet. Based on our lease portfolio at December 31, 2017, the right-of-use asset and lease liability would have been in the range of $40 million to $45 million on our Consolidated Balance Sheets based on the remaining lease payments, with no material impact to our Consolidated Statement of Operations or liquidity. However, the ultimate impact of adopting ASU 2016-02 will depend on the Company’s lease portfolio as of the adoption date.

We classified these investments as Level 2 since the fair value is based on market observable inputs for investments with similar terms and maturities. (2) The deferred compensation liability, included in “Other liabilities—other” in our Condensed Consolidated Balance Sheets, consists of deferrals under The New York Times Company Deferred Executive Compensation Plan (the “DEC”), which enables certain eligible executives to elect to defer a portion of their compensation on a pre-tax basis. The deferred amounts are invested at the executives’ option in various mutual funds. The fair value of deferred compensation is based on the mutual fund investments elected by the executives and on quoted prices in active markets for identical assets. Participation in the DEC was frozen effective December 31, 2015.
