The amendments are effective for all organizations for fiscal years beginning after December 15, 2018, and interim periods within those fiscal years. Early adoption is permitted. We are currently in the process of evaluating the impact of this guidance on our consolidated financial statements.</font></div><div style="line-height:120%;padding-bottom:8px;text-align:left;text-indent:36px;font-size:10pt;"><font style="font-family:Palatino,serif;font-size:10pt;">In March 2017, the FASB issued ASU 2017-07, “Compensation - Retirement Benefits (Topic 715): Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost.” The new guidance requires the service cost component to be presented separately from the other components of net benefit costs related to single-employer pension plans and other postretirement benefits plans. Service cost will be presented with other employee compensation cost within operations. The other components of net benefit cost, such as interest cost, amortization of prior service cost and gains or losses are required to be presented outside of operations. The new guidance is effective for fiscal years beginning after December 15, 2017, and interim periods within those fiscal years. Early adoption is permitted. 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 the changes required in ASU 2017-07 only change the Consolidated Statements of Operations classification of the components of net periodic benefit cost, no changes will be made to net income. Upon adoption of the ASU during the first quarter of 2018, the Company will separately present the components of net periodic benefit cost or income related to single-employer pension plans and other postretirement benefits plans, excluding the service cost component, in non-operating expenses on a retrospective basis. Refer to Note 9 and Note 10 for components of net periodic benefit cost related to single-employer pension plans and other postretirement benefits, respectively.</font></div><div style="line-height:120%;padding-bottom:8px;text-align:left;text-indent:36px;font-size:10pt;"><font style="font-family:Palatino,serif;font-size:10pt;">In January 2017, the FASB issued ASU 2017-04, Intangibles - Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment, which eliminates step two from the goodwill impairment test. Under ASU 2017-04, an entity should recognize an impairment charge for the amount by which the carrying amount of a reporting unit exceeds its fair value up to the amount of goodwill allocated to that reporting unit. This guidance will be effective for us in the first quarter of 2020 on a prospective basis, and early adoption is permitted. The Company is in the process of evaluating the impact that this guidance will have on its consolidated financial statements. However, we do not expect the adoption of the standard to have a material effect on our consolidated financial statements.</font></div><div style="line-height:120%;padding-bottom:8px;text-align:left;text-indent:36px;font-size:10pt;"><font style="font-family:Palatino,serif;font-size:10pt;">In January 2017, the FASB issued ASU 2017-01, Business Combinations (Topic 805) : Clarifying the Definition of a Business, which provides guidance to assist companies with evaluating whether transactions should be accounted for as acquisitions (or disposals) of assets or businesses. The guidance is effective for interim and annual periods beginning after December 15, 2017. The adoption of this standard is not expected to have a material impact on the consolidated financial statements of the Company. </font></div><div style="line-height:120%;padding-bottom:8px;text-align:left;text-indent:36px;font-size:10pt;"><font style="font-family:Palatino,serif;font-size:10pt;">In November 2016, the FASB issued ASU 2016-18, “Statement of Cash Flow: Restricted Cash,” which amends the guidance in Accounting Standards Codification (“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 and 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, restricted cash, and restricted cash equivalents, (3) changes in restricted cash and restricted cash equivalents that result from transfers between cash, cash equivalents, and restricted cash and restricted cash equivalents 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 and restricted cash equivalents must disclose information about the nature of the restrictions. This guidance becomes effective for Company for fiscal years beginning after December 15, 2017, and interim periods within those fiscal years. Early adoption is permitted. Upon adoption of the standard during the first quarter of 2018, the Company will include the restricted cash balance with cash and cash equivalents balances in the statements of cash flows on a retrospective basis. Cash flows provided by investing activities will decrease by </font><font style="font-family:Palatino,serif;font-size:10pt;">$6.9 million</font><font style="font-family:Palatino,serif;font-size:10pt;"> and </font><font style="font-family:Palatino,serif;font-size:10pt;">$3.8 million</font><font style="font-family:Palatino,serif;font-size:10pt;"> for the fiscal years ended December 31, 2017 and December 25, 2016, respectively. The Company will add a reconciliation from Condensed Consolidated Balance Sheets to Condensed Consolidated Statement of Cash Flows in the first quarter of 2018.</font></div><div style="line-height:120%;padding-bottom:8px;text-align:left;text-indent:36px;font-size:10pt;"><font style="font-family:Palatino,serif;font-size:10pt;">In August 2016, the FASB issued ASU 2016-15, “Statement of Cash Flows: Classification of Certain Cash Receipts and Cash Payments,” which amends the guidance in ASC 230 on the classification of certain cash receipts and cash payments in the statement of cash flows. The primary purpose of this ASU is to reduce the diversity in practice that has resulted from the lack of consistent principles on this topic. The ASU’s amendments add or clarify guidance on eight cash flows issues: debt prepayment or debt extinguishment costs, settlement of zero-coupon debt instruments or other debt instruments with coupon interest rates that are insignificant in relation to the effective interest rate of the borrowing, contingent consideration payments made after a business combination, proceeds from the settlement of insurance claims, proceeds from the settlement of corporate-owned life insurance policies, including bank-owned life insurance policies, distributions received from equity method investees, beneficial interests in securitization transactions, and separately identifiable cash flows and application of the predominance principle. This guidance becomes effective for the Company for fiscal years beginning after December 15, 2017, and interim periods within those fiscal years. Early adoption is permitted, including adoption in an interim period. All amendments must be adopted in the same period. Since proceeds and premiums of corporate-owned life insurance policies and the return on equity investment are currently classified as cash flows from investing activities, we do not expect the adoption of the standard to have a material effect on our consolidated financial statements. </font></div><div style="line-height:120%;padding-bottom:8px;text-align:left;text-indent:36px;font-size:10pt;"><font style="font-family:Palatino,serif;font-size:10pt;">In June 2016, FASB issued ASU 2016-13, “Financial Instruments - Credit Losses.” The new guidance introduces an approach based on expected losses to estimate credit losses on certain types of financial instruments. It also modifies the impairment model for available-for-sale (AFS) debt securities and provides for a simplified accounting model for purchased financial assets with credit deterioration since their origination. The new guidance is effective for 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. We are currently in the process of evaluating the impact of this guidance on our consolidated financial statements.</font></div><div style="line-height:120%;padding-bottom:8px;text-align:left;text-indent:36px;font-size:10pt;"><font style="font-family:Palatino,serif;font-size:10pt;">In February 2016, the FASB issued ASU 2016-02, “Leases,” which 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. This guidance becomes effective for the Company for fiscal years beginning after December 30, 2018. Early application is permitted. This guidance is expected to be applied on a modified retrospective basis for leases existing at, or entered into after, the earliest period presented in the financial statements. We are currently in the process of evaluating the impact of the new leasing guidance and expect that most of our operating lease commitments will be subject to the new standard. The adoption of the standard will have the most significant change on our balance sheet as it will require us to record right-of-use assets and lease liabilities. Based upon our initial evaluation, we do not expect the adoption of the standard to have a material effect on our results of operations and liquidity. </font></div><div style="line-height:120%;padding-bottom:8px;text-align:left;text-indent:36px;font-size:10pt;"><font style="font-family:Palatino,serif;font-size:10pt;">In January 2016, the FASB issued ASU 2016-01, “Financial Instruments-Overall: Recognition and Measurement of Financial Assets and Financial Liabilities” which 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. The new guidance is effective for fiscal years beginning after December 15, 2017, and interim periods within those fiscal years. Early adoption is permitted. The amendments related to equity securities without readily determinable fair values for which the measurement alternative is applied should be applied prospectively to equity investments that exist as of the date of adoption. We expect to elect the measurement alternative, defined as cost, less impairments, adjusted by observable price changes. Starting the fourth quarter of 2017, we have renamed “Interest expense, net” as “Interest expense and other, net” to account for non-operational income or expense and any impairments or remeasurement of our non-equity method investments as a result of adopting this ASU. We anticipate that the adoption of the standard may increase the volatility of our Interest expense and other, net, as a result of the remeasurement of our equity investments upon the occurrence of observable price changes and impairments.</font></div><div style="line-height:120%;padding-bottom:8px;text-align:left;text-indent:36px;font-size:10pt;"><font style="font-family:Palatino,serif;font-size:10pt;">In May 2014, the FASB issued ASU 2014-09, “Revenue from Contracts with Customers,” which prescribes a single comprehensive model for entities to use in the accounting of revenue arising from contracts with customers. The new guidance will supersede virtually all existing revenue guidance under GAAP and is effective for fiscal years beginning after December 31, 2017. There are two transition options available to entities: the full retrospective approach or the modified retrospective approach. Under the full retrospective approach, the Company would restate prior periods in compliance with ASC 250, “Accounting Changes and Error Corrections.” Alternatively, the Company may elect the modified retrospective approach, which allows for the new revenue standard to be applied to existing contracts as of the effective date with a cumulative catch-up adjustment recorded to retained earnings. We will adopt the new standard using the modified retrospective method beginning January 1, 2018.</font></div><div style="line-height:120%;padding-bottom:8px;text-align:left;text-indent:36px;font-size:10pt;"><font style="font-family:Palatino,serif;font-size:10pt;"> Subsequently, in March 2016, the FASB issued ASU 2016-08, “Revenue from Contracts with Customers (Topic 606): Principal versus Agent Considerations (Reporting Revenue Gross versus Net),” which clarifies the implementation guidance on principal versus agent considerations in ASU 2014-09. In April 2016, the FASB also issued ASU 2016-10, “Revenue from Contracts with Customers (Topic 606): Identifying Performance Obligations and Licensing,” to reduce the cost and complexity of applying the guidance on identifying promised goods or services when identifying a performance obligation and improve the operability and understandability of the licensing implementation guidance. In May 2016, the FASB issued ASU 2016-12, “Revenue from Contracts with Customers (Topic 606): Narrow-Scope Improvements and Practical Expedients,” to reduce the cost and complexity of applying the guidance to address certain issues on assessing collectability, presentation of sales taxes, noncash consideration, and completed contracts and contract modifications at transition. The amendments in ASU 2016-08, 2016-10, and 2016-12 do not change the core principle of ASU 2014-09. </font></div><div style="line-height:120%;padding-bottom:13px;text-align:left;text-indent:36px;font-size:10pt;"><font style="font-family:Palatino,serif;font-size:10pt;">Based upon our evaluation, the adoption of the standards will not have a material effect on our financial condition or results of operations. Our subscription and advertising revenues will not be impacted by the new guidance. The most significant changes will be primarily related to how we account for certain licensing arrangements in the other revenue category for which archival and updated content is included. Under the current revenue guidance, licensing revenue is generally recognized based on the annual minimum guarantee amount specified in the contractual agreement with the licensee as a single deliverable. 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 will be recognized at the commencement of the contract when control of the archival content is transferred. Based on the modified retroactive approach, 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 will accelerate the revenue of contracts not completed as of January 1, 2018 and we expect that the adjustment to opening retained earnings will be an increase in the range of approximately </font><font style="font-family:Palatino,serif;font-size:10pt;">$3 million</font><font style="font-family:Palatino,serif;font-size:10pt;"> to </font><font style="font-family:Palatino,serif;font-size:10pt;">$6 million</font><font style="font-family:Palatino,serif;font-size:10pt;">.</font></div><div style="line-height:120%;padding-bottom:8px;text-align:left;text-indent:36px;font-size:10pt;"><font style="font-family:Palatino,serif;font-size:10pt;">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. </font></div></div>
