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 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 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 Consolidated Statements of Operations below “Operating profit” on a retrospective basis. The Company reclassified $0.9 million and $4.2 million of credits from “Production costs” and “Selling and general and administrative costs,” respectively, to “Other components of net periodic benefit costs/(income)” in 2017. Additionally, in 2017, the Company recorded a gain of $32.7 million in connection with the settlement of contractual funding obligations primarily from a postretirement plan, as well as a pension settlement charges of $102.1 million in connection with the transfer of certain pension benefit obligations to insurers that were reclassified from “Postretirement benefit plan withdrawl expense” and “Pension settlement expense”, respectively, to “Other components of net periodic benefit costs”. This recast increased the full year 2017 “Operating costs” by $5.1 million while “Operating profit” increased $64.2. The Company reclassified $1.3 million and $7.2 million of credits from “Production costs” and “Selling and general and administrative costs,” respectively, to “Other components of net periodic benefit costs/(income)” during 2016. Additionally, in 2016 the Company reclassified $1.7 million of pension credits out of “Restructuring charge” and $21.3 million of pension settlement charges out of “Pension settlement expense” into “Other components of net periodic benefit costs”. This recast increased the full year 2016 “Operating costs” by $8.5 million while “Operating profit” increased $11.1 million. There was no impact to net income for 2017 or 2016. See Note 10 for the components of net periodic benefit costs/(income) for our pension and other postretirement benefits plans. </font></div><div style="font-size:8pt;"><font style="font-family:Helvetica,sans-serif;font-size:8pt;"><br clear="none"/></font></div></td></tr></table></div></div><div style="line-height:120%;padding-bottom:8px;text-align:left;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;"><br clear="none"/></font></div><div style="line-height:120%;padding-bottom:8px;text-align:left;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;"><br clear="none"/></font></div><div style="line-height:120%;padding-bottom:8px;text-align:left;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;"><br clear="none"/></font></div><div style="line-height:120%;padding-bottom:8px;text-align:left;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;"><br clear="none"/></font></div><div style="line-height:120%;padding-bottom:8px;text-align:left;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;"><br clear="none"/></font></div><div style="line-height:120%;padding-bottom:8px;text-align:left;font-size:10pt;"><div style="padding-left:0px;text-indent:0px;line-height:normal;padding-top:10px;"><table cellpadding="0" cellspacing="0" style="font-family:Times New Roman;font-size:10pt;width:93.48659003831418%;border-collapse:collapse;text-align:left;"><tr><td colspan="4" rowspan="1"></td></tr><tr><td style="width:14%;" rowspan="1" colspan="1"></td><td style="width:13%;" rowspan="1" colspan="1"></td><td style="width:15%;" rowspan="1" colspan="1"></td><td style="width:58%;" rowspan="1" colspan="1"></td></tr><tr><td style="vertical-align:bottom;border-bottom:1px solid #000000;background-color:#acacac;padding-left:2px;padding-top:2px;padding-bottom:2px;padding-right:2px;" rowspan="1" colspan="1"><div style="text-align:center;font-size:8pt;"><font style="font-family:Helvetica,sans-serif;font-size:8pt;font-weight:bold;">Accounting Standard Update(s)</font></div></td><td style="vertical-align:bottom;border-bottom:1px solid #000000;background-color:#acacac;padding-left:2px;padding-top:2px;padding-bottom:2px;padding-right:2px;" rowspan="1" colspan="1"><div style="text-align:center;font-size:8pt;"><font style="font-family:Helvetica,sans-serif;font-size:8pt;font-weight:bold;">Topic</font></div></td><td style="vertical-align:bottom;border-bottom:1px solid #000000;background-color:#acacac;padding-left:2px;padding-top:2px;padding-bottom:2px;padding-right:2px;" rowspan="1" colspan="1"><div style="text-align:center;font-size:8pt;"><font style="font-family:Helvetica,sans-serif;font-size:8pt;font-weight:bold;">Effective Period</font></div></td><td style="vertical-align:bottom;border-bottom:1px solid #000000;background-color:#acacac;padding-left:2px;padding-top:2px;padding-bottom:2px;padding-right:2px;" rowspan="1" colspan="1"><div style="text-align:center;font-size:8pt;"><font style="font-family:Helvetica,sans-serif;font-size:8pt;font-weight:bold;">Summary</font></div></td></tr><tr><td style="vertical-align:middle;padding-left:2px;padding-top:2px;padding-bottom:2px;padding-right:2px;" rowspan="1" colspan="1"><div style="text-align:center;font-size:8pt;"><font style="font-family:Helvetica,sans-serif;font-size:8pt;">2016-18</font></div></td><td style="vertical-align:middle;padding-left:2px;padding-top:2px;padding-bottom:2px;padding-right:2px;" rowspan="1" colspan="1"><div style="text-align:center;font-size:8pt;"><font style="font-family:Helvetica,sans-serif;font-size:8pt;">Statement of Cash Flow: Restricted Cash</font></div></td><td style="vertical-align:middle;padding-left:2px;padding-top:2px;padding-bottom:2px;padding-right:2px;" rowspan="1" colspan="1"><div style="text-align:center;font-size:8pt;"><font style="font-family:Helvetica,sans-serif;font-size:8pt;">Fiscal years beginning after December 15, 2017, and interim periods within those fiscal years.

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. </font></div><div style="text-indent:36px;font-size:8pt;"><font style="font-family:Helvetica,sans-serif;font-size:8pt;">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. </font></div><div style="text-indent:36px;font-size:8pt;"><font style="font-family:Helvetica,sans-serif;font-size:8pt;">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. </font></div><div style="text-indent:36px;font-size:8pt;"><font style="font-family:Helvetica,sans-serif;font-size:8pt;">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 was a decrease of $1.3 million for the twelve months ended December 30, 2018.</font></div><div style="text-indent:36px;font-size:8pt;"><font style="font-family:Helvetica,sans-serif;font-size:8pt;">Our subscription and advertising revenues were not affected by the new guidance.

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.

The guidance issued in 2016 was subsequently amended in the 2018 ASU updates (collectively, “Topic 842”). Topic 842 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. It requires that reimbursable expenses from a lessee be reported gross on the Consolidated Statement of Operations.</font></div><div style="text-align:justify;text-indent:36px;font-size:8pt;"><font style="font-family:Helvetica,sans-serif;font-size:8pt;">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.</font></div><div style="text-align:justify;text-indent:36px;font-size:8pt;"><font style="font-family:Helvetica,sans-serif;font-size:8pt;">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 30, 2018, the right-of-use asset and lease liability would have been in the range of $35 million to $40 million on our Consolidated Balance Sheets based on the remaining lease payments. We do not expect the lessee guidance to have a material impact to our Consolidated Statement of Operations or liquidity. </font></div><div style="text-align:justify;font-size:8pt;"><font style="font-family:Helvetica,sans-serif;font-size:8pt;"><br clear="none"/></font></div></td></tr></table></div></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.
