Description of Business And Basis of Presentation [Abstract]
Description of Business and Basis of Presentation [Text Block]	Description of Business and Basis of Presentation Description of Business The Madison Square Garden Company (together with its subsidiaries, the “Company” or “ Madison Square Garden ”) is a live sports and entertainment business. The Company classifies its business interests into two reportable segments: MSG Entertainment and MSG Sports. MSG Entertainment includes live entertainment events such as concerts, family shows, performing arts and special events, which are presented or hosted in the Company’s diverse collection of venues along with live offerings through TAO Group Holdings LLC (“ TAO Group ”) and Boston Calling Events LLC (“ BCE ”). TAO Group is a hospitality group with globally-recognized entertainment dining and nightlife brands: TAO, Marquee, Lavo, Avenue, The Stanton Social, Beauty & Essex and Vandal. BCE produces New England’s premier Boston Calling Music Festival. MSG Entertainment also includes the Company’s original productions — the Christmas Spectacular Starring the Radio City Rockettes (the “ Christmas Spectacular ”) and the New York Spectacular Starring the Radio City Rockettes (the “ New York Spectacular ”). MSG Sports includes the Company’s professional sports franchises: the New York Knicks (the “ Knicks ”) of the National Basketball Association (the “ NBA ”), the New York Rangers (the “ Rangers ”) of the National Hockey League (the “ NHL ”), the New York Liberty (the “ Liberty ”) of the Women’s National Basketball Association (the “ WNBA ”), the Hartford Wolf Pack of the American Hockey League (the “ AHL ”) and the Westchester Knicks of the NBA Gatorade League (the “ NBAGL ”). The MSG Sports segment also includes other live sporting events, including professional boxing, college basketball, college hockey, professional bull riding, mixed martial arts, esports, tennis and college wrestling, all of which the Company promotes, produces and/or presents. In July 2017, the Company acquired a controlling interest in Counter Logic Gaming (“ CLG ”), a premier North American esports organization, which is now part of the MSG Sports segment. The Company conducts a significant portion of its operations at venues that it either owns or operates under long-term leases. The Company owns the Madison Square Garden Arena (“ The Garden ”) and The Theater at Madison Square Garden in New York City, the Forum in Inglewood, CA and The Chicago Theatre in Chicago. In addition, the Company leases Radio City Music Hall and the Beacon Theatre in New York City, and has a booking agreement with respect to the Wang Theatre in Boston. Additionally, TAO Group operates various restaurants, nightlife and hospitality venues under long-term leases and management contracts in New York, Las Vegas, Los Angeles, Australia and Singapore. The Company was incorporated on March 4, 2015 as an indirect, wholly-owned subsidiary of MSG Networks Inc. (“ MSG Networks ”), formerly known as The Madison Square Garden Company. On September 11, 2015, MSG Networks ’ board of directors approved the distribution of all the outstanding common stock of Madison Square Garden to MSG Networks’ stockholders (the “ Distribution ”), which occurred on September 30, 2015. See Note 1 to the consolidated and combined financial statements included in the Company’s Annual Report on Form 10-K for the year ended June 30, 2017 for more information regarding the Distribution to its common stockholders. Basis of Presentation The accompanying unaudited consolidated interim financial statements (referred to as the “ Financial Statements ” herein) have been prepared in accordance with U.S. generally accepted accounting principles (“ GAAP ”) and Article 10 of Regulation S-X of the U.S. Securities and Exchange Commission (“ SEC ”) for interim financial information, and should be read in conjunction with the Company’s Annual Report on Form 10-K for the year ended June 30, 2017 . The Financial Statements presented in this Quarterly Report on Form 10-Q are unaudited; however, in the opinion of management, the Financial Statements reflect all adjustments, consisting solely of normal recurring adjustments, necessary for a fair presentation of the results for the interim periods presented. The results of operations for the periods presented are not necessarily indicative of the results that might be expected for future interim periods or for the full year. The dependence of the MSG Sports segment on revenues from its NBA and NHL sports teams generally means it earns a disproportionate share of its revenues in the second and third quarters of the Company’s fiscal year. The dependence of the MSG Entertainment segment on revenues from the Christmas Spectacular generally means it earns a disproportionate share of its revenues in the second quarter of the Company’s fiscal year.

Accounting Policies

Accounting Policies [Abstract]
Accounting Policies [Text Block]	Principles of Consolidation The consolidated financial statements of the Company include the accounts of The Madison Square Garden Company and its subsidiaries. All significant intercompany transactions and balances have been eliminated in consolidation. In addition, the consolidated financial statements of the Company include the accounts from TAO Group , BCE and CLG , in which the Company has controlling voting interests. The Company’s consolidation criteria are based on authoritative accounting guidance for voting interest, controlling interest or variable interest entities. TAO Group , BCE and CLG are consolidated with the equity owned by other shareholders shown as redeemable or nonredeemable noncontrolling interests in the accompanying consolidated balance sheet s, and the other shareholders’ portion of net earnings (loss) and other comprehensive income (loss) shown as net income (loss) or comprehensive income (loss) attributable to redeemable or nonredeemable noncontrolling interests in the accompanying consolidated statements of operation s and consolidated statements of comprehensive income , respectively. See Note 2 to the consolidated and combined financial statements included in the Company’s Annual Report on Form 10-K for the year ended June 30, 2017 for more information regarding the classification of redeemable noncontrolling interests of TAO Group . In addition, TAO Group ’s results are reported on a three-month lag basis and TAO Group reports on a fiscal year reflecting the retail-based calendar (containing 4-4-5 week calendar quarters). Accordingly, the Company’s results for the three and six months ended December 31, 2017 include TAO Group ’s operating results from June 26, 2017 to September 24, 2017 and March 27, 2017 to September 24, 2017 , respectively. Use of Estimates The preparation of the accompanying Financial Statements in conformity with GAAP requires management to make estimates and assumptions about future events. These estimates and the underlying assumptions affect the amount of assets and liabilities reported, disclosures about contingent assets and liabilities, and reported amounts of revenues and expenses. Such estimates include the valuation of accounts receivable, investments, goodwill, intangible assets, other long-lived assets, tax accruals and other liabilities. In addition, estimates are used in revenue recognition, revenue sharing expense (net of escrow), luxury tax expense, income tax expense, performance and share-based compensation, depreciation and amortization, litigation matters and other matters, as well as in the valuation of contingent consideration and noncontrolling interests resulting from business combination transactions. Management believes its use of estimates in the Financial Statements are reasonable. Management evaluates its estimates on an ongoing basis using historical experience and other factors, including the general economic environment and actions it may take in the future. The Company adjusts such estimates when facts and circumstances dictate. However, these estimates may involve significant uncertainties and judgments and cannot be determined with precision. In addition, these estimates are based on management’s best judgment at a point in time and, as such, these estimates may ultimately differ from actual results. Changes in estimates resulting from weakness in the economic environment or other factors beyond the Company’s control could be material and would be reflected in the Company’s financial statements in future periods. Summary of Significant Accounting Policies The following is an update to the Company’s Summary of Significant Accounting Policies disclosed in its Annual Report on Form 10-K for the year ended June 30, 2017 : Revenue Recognition Deferred revenue reported in the accompanying consolidated balance sheets as of December 31, 2017 and June 30, 2017 includes amounts due to the third-party promoters of $50,414 and $72,400 , respectively. Foreign Currency Translation The consolidated financial statements are presented in U.S. Dollars. Assets and liabilities of non-U.S. subsidiaries that operate in a local currency environment, where that local currency is the functional currency, are translated to U.S. Dollars at exchange rates in effect at the balance sheet date. Operating results of non-U.S. subsidiaries are translated at weighted-average exchange rates during the year which approximate the rates in effect at the transaction dates. Foreign currency translation gains and losses are included as a component of accumulated other comprehensive income (loss) as changes in cumulative translation adjustments in the accompanying consolidated balance sheet. Recently Issued Accounting Pronouncements Recently Adopted Accounting Pronouncements In March 2016, the Financial Accounting Standards Board (“ FASB ”) issued Accounting Standards Update (“ ASU ”) No. 2016-07, Investments - Equity Method and Joint Ventures (Topic 323), Simplifying the Transition to the Equity Method of Accounting . ASU No. 2016-07 eliminates the requirement for an investor to retrospectively apply the equity method when an investment that it had accounted for by another method qualifies for use of the equity method. This standard was adopted by the Company prospectively in the first quarter of fiscal year 2018. The adoption of the standard did not have an impact on the Company’s consolidated financial statements. In March 2016, the FASB issued ASU No. 2016-09, Compensation - Stock Compensation (Topic 718): Improvements to Employee Share-based Payment Accounting . ASU No. 2016-09, among other things, (i) requires the income tax effects of all awards to be recognized in the statement of operations when the awards vest or are settled, (ii) allows an employer to repurchase more of an employee’s shares for tax withholding purposes than currently allowable, without triggering liability accounting, and provides companies with the option to make a policy election to account for forfeitures as they occur, and (iii) requires companies to present excess tax benefits as operating activity rather than as financing activity on the statement of cash flows. This standard was adopted by the Company in the first quarter of fiscal year 2018. In connection with the Company’s election to record forfeitures as they occur, the Company used the modified retrospective transition method and recorded a cumulative effect of $2,403 , which was an increase in beginning accumulated deficits with the offset by an equal increase in additional paid in capital. In addition, the Company prospectively adopted the provision regarding the presentation of excess tax benefits in the statement of cash flows, which did not result in a change in the net cash provided by operating activities for the six months ended December 31, 2017 because the Company currently maintains a 100% valuation allowance on its deferred tax asset. In May 2017, the FASB issued ASU No. 2017-09, Compensation - Stock Compensation (Topic 718): Scope of Modification Accounting. ASU No. 2017-09 provides clarification on when modification accounting should be used for changes to the terms or conditions of a share-based payment award. This standard does not change the accounting for modifications but clarifies that modification accounting guidance should only be applied if there is a change to the value, vesting conditions or award classification and would not be required if the changes are considered non-substantive. This standard was early adopted by the Company prospectively in the first quarter of fiscal year 2018. The adoption of the standard did not have an impact on the Company’s consolidated financial statements. Recently Issued Accounting Pronouncements Not Yet Adopted In May 2014, the FASB issued ASU No. 2014-09, Revenue from Contracts with Customers ( Topic 606 ) , which supersedes the revenue recognition requirements in FASB Accounting Standards Codification (“ ASC ”) Topic 605, Revenue Recognition . ASC Topic 606 , among other things, (i) is based on the principle that revenue is recognized to depict the transfer of goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange f or those goods or services, and (ii) requires additional disclosure about the nature, amount, timing and uncertainty of revenue and cash flows arising from customer contracts, including significant judgments and changes in judgments and assets recognized from costs incurred to obtain or fulfill a contract. In August 2015, the FASB issued ASU No. 2015-14 , Revenue from Contracts with Customers (Topic 606) : Deferral of the Effective Date , which defers the effective date of ASU No. 2014-09 for all entities by one year. In March 2016, the FASB issued ASU No. 2016-08, Revenue from Contracts with Customers (Topic 606), Principal versus Agent Considerations (Reporting Revenue versus Net) , which clarifies the implementation guidance on principal versus agent considerations in the new revenue recognition standard under ASU No. 2014-09. ASU No. 2016-08 clarifies how an entity should identify the unit of accounting (i.e. the specified good or service) for the principal versus agent evaluation and how it should apply the control principle to certain types of arrangements. In April 2016, the FASB issued ASU No. 2016-10, Revenue from Contracts with Customers (Topic 606): Identifying Performance Obligations and Licensing , which clarifies the principle in ASU No 2014-09 for determining whether a good or service is separately identifiable from other promises in the contract and, therefore, should be accounted for separately. ASU No. 2016-10 also clarifies that entities are not required to identify promised goods or services that are immaterial in the context of the contract and allows entities to elect to account for shipping and handling activities as a fulfillment cost rather than as an additional promised service. In May 2016, the FASB issued ASU No. 2016-12, Revenue from Contracts with Customers (Topic 606) - Narrow-Scope Improvements and Practical Expedients , which clarifies the following aspects in ASU No. 2014-09: collectability, presentation of sales taxes and other similar taxes collected from customers, noncash considerations, contract modifications at transition, completed contracts at transition, and technical correction. In December, the FASB issued ASU No. 2016-20, Technical Corrections and Improvements to Topic 606, Revenue from Contracts with Customers , which allows entities not to make quantitative disclosures about remaining performance obligations in certain cases and requires entities that use any of the new or previously existing optional exemptions to expand their qualitative disclosures. ASC Topic 606 and the related updates will be effective for the Company beginning in the first quarter of fiscal year 2019 using one of two retrospective application methods. The Company’s evaluation of the impact this standard will have on its consolidated financial statements is ongoing. Based on the review to date, the Company believes that the adoption of the new standard will impact the quarterly and annual recognition for certain revenue streams. While the Company has made substantial progress in concluding the appropriate treatment for most of its revenue streams, the review is ongoing for a few remaining revenue streams. The Company has not decided whether the retrospective or modified retrospective method will be used in adopting the new standard. In January 2016, the FASB issued ASU No. 2016-01, Financial Instruments - Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities, addresses certain aspects of recognition, measurement, presentation, and disclosure of financial instruments. This standard, among other things, (i) requires equity investments, with certain exceptions, to be measured at fair value with changes in fair value recognized in net income and (ii) simplifies the impairment assessment of equity investments without readily determinable fair values by requiring a qualitative assessment to identify impairment. Early adoption is not permitted with the exception of certain provisions related to the presentation of other comprehensive income. This standard will be effective for the Company beginning in the first quarter of fiscal year 2019. The Company is currently evaluating the impact this standard will have on its consolidated financial statements. In February 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842) , which supersedes existing guidance on accounting for leases in FASB ASC Topic 840, Leases . ASU No. 2016-02, among other things, (i) requires lessees to account for leases as either finance leases or operating leases and generally requires all leases to be recorded on the balance sheet, including those leases classified as operating leases under previous accounting guidance, through the recognition of right-of-use assets and corresponding lease liabilities, and (ii) requires extensive qualitative and quantitative disclosures about leasing activities. The accounting applied by a lessor is largely unchanged from that applied under previous accounting guidance. This standard will be effective for the Company beginning in the first quarter of fiscal year 2020 and is required to be applied using the modified retrospective approach for all leases existing as of the effective date. Early adoption is permitted; however, the Company currently does not plan to adopt this standard early. The Company’s evaluation of the impact this standard will have on its consolidated financial statements is ongoing. Based on efforts to date, the adoption of the standard will result in the recognition of right of use assets and lease liabilities related to the Company’s operating leases. In June 2016, the FASB issued ASU 2016-13, Financial Instruments - Credit Losses . ASU 2016-13 replaces the incurred loss impairment methodology in current U.S. GAAP with a methodology that will require the reflection of expected credit losses and will also require consideration of a broader range of reasonable and supportable information to determine credit loss estimates. For most financial instruments, the standard will require the use of a forward-looking expected loss model rather than the incurred loss model for recognizing credit losses, which will generally result in the earlier recognition of credit losses on financial instruments. This standard will be effective for the Company beginning in the first quarter of fiscal year 2021, with early adoption permitted. The Company is currently evaluating the impact this standard will have on its consolidated financial statements. In August 2016, the FASB issued ASU No. 2016-15, Statement of Cash Flows (Topic 230). ASU No. 2016-15 addresses eight specific cash flow issues and is intended to reduce diversity in practice in how certain cash receipts and cash payments are presented and classified in the statement of cash flows. This standard will be effective for the Company beginning in the first quarter of fiscal year 2019. Early adoption is permitted. The adoption of this standard is not expected to have a material impact on the Company’s consolidated financial statements. In October 2016, the FASB issued ASU No. 2016-16, Income Taxes (Topic 740): Intra-Entity Transfers of Assets Other Than Inventory . ASU No. 2016-16 requires entities to recognize income tax consequences of an intra-entity transfer of an asset other than inventory when the transfer occurs. This standard will be effective for the Company beginning in the first quarter of fiscal year 2019. Early adoption is permitted as of the beginning of an annual reporting period for which financial statements have not been issued or made available for issuance. The adoption of this standard is not expected to have a material impact on the Company’s consolidated financial statements. In November 2016, the FASB issued ASU No. 2016-18, Statement of Cash Flows: Restricted Cash . The primary purpose of ASU No. 2016-18 is to reduce the diversity in practice that exists in the classification and presentation of changes in restricted cash on the statement of cash flows. This standard will require that a statement of cash flows explain the change during the period in the total of cash, cash equivalents, and amounts generally described as restricted cash or restricted cash equivalents. Therefore, amounts generally described as restricted cash and restricted cash equivalents should be included with cash and cash equivalents when reconciling the beginning-of-period and end-of-period total amounts shown on the statement of cash flows. This standard will be effective retrospectively for the Company beginning in the first quarter of fiscal year 2019, and will result in a change to the Company’s presentation of net cash provided by (used in) operating activities in the statement of cash flows for the impact of changes in restricted cash balances. Early adoption is permitted in any interim or annual period. In January 2017, the FASB issued ASU No. 2017-01, Business Combinations (Topic 805) Clarifying the Definition of a Business . The primary purpose of this ASU is to clarify the definition of a business with the objective of adding guidance to assist entities with evaluating whether transactions should be accounted for as acquisitions (or disposals) of assets or businesses, which will affect many areas of accounting including acquisitions, disposals, goodwill, and consolidation. This standard will be effective for the Company beginning in the first quarter of fiscal year 2019 and is required to be applied prospectively. Early adoption is permitted. The adoption of this standard is not expected to have a material impact on the Company’s consolidated financial statements. In January 2017, the FASB issued ASU No. 2017-04, Intangibles - Goodwill and Other (Topic 350): Simplifying the Accounting for Goodwill Impairment. ASU No. 2017-04 removes Step 2 of the goodwill impairment test, which requires a hypothetical purchase price allocation. A goodwill impairment will now be the amount by which a reporting unit’s carrying value exceeds its fair value, not to exceed the carrying amount of goodwill. This standard will be effective for the Company beginning in the first quarter of fiscal year 2021 and is required to be applied prospectively. Early adoption is permitted for interim or annual goodwill impairment tests performed on testing dates after January 1, 2017. The adoption of this standard is not expected to have a material impact on the Company’s consolidated financial statements. In March 2017, the FASB issued ASU No. 2017-07, Compensation - Retirement Benefits (Topic 715): Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost. ASU No. 2017-07 requires employers to disaggregate the service cost component from the other components of net benefit cost and disclose by line item the amount of net benefit cost that is included in the statement of operations or capitalized in assets. The standard requires employers to report the service cost component in the same line item(s) as other compensation costs arising from services rendered by the pertinent employees during the period and to report other components of net benefit cost separately and outside the subtotal of operating income. The standard also allows only the service cost component to be eligible for capitalization. This standard will be effective for the Company beginning in the first quarter of fiscal year 2019. The guidance requires application on a retrospective basis for the presentation of the service cost component and the other components of net benefit cost in the statements of operations and on a prospective basis for the capitalization of the service cost component of net benefit cost in assets. Early adoption is permitted as of the beginning of an annual reporting period for which financial statements have not been issued or made available for issuance. For the three months ended December 31, 2017 , net periodic pension and other postretirement employee benefit cost reported within operating income totaled to $1,031 , of which $53 represented service cost. For the six months ended December 31, 2017 , net periodic pension and other postretirement employee benefit cost reported within operating income totaled to $2,093 , of which $105 represented service cost.

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies [Text Block]	Commitments and Contingencies Commitments As more fully described in Note 8 to the consolidated and combined financial statements included in the Company’s Annual Report on Form 10-K for the year ended June 30, 2017 , the Company’s commitments consist primarily of (i) the MSG Sports segment’s obligations under employment agreements that the Company has with its professional sports teams’ personnel that are generally guaranteed regardless of employee injury or termination, (ii) long-term noncancelable operating lease agreements primarily for entertainment venues, and corporate offices, and (iii) revolving credit facilities provided by the Company to AMSGE and Tribeca Enterprises (see Note 6 ). The Company did not have any material changes in its contractual obligations since the end of fiscal year 2017 other than activities in the ordinary course of business. In connection with the TAO Group and CLG acquisitions, the Company has accrued contingent consideration as part of the purchase price allocation. See Note 10 for further details of the amount recorded in the accompanying consolidated balance sheet as of December 31, 2017 . In addition, see Note 10 to the consolidated and combined financial statements included in the Company’s Annual Report on Form 10-K for the year ended June 30, 2017 regarding the principal repayments required under the TAO Group ’s senior secured term loan facility. Legal Matters The Company owns 50% of AMSGE , which in turn owns a majority interest in Global Music Rights, LLC (“GMR”). GMR is primarily a performance rights organization, whose business includes obtaining the right to license the public performance rights of songs composed by leading songwriters. GMR engaged in negotiations with the Radio Music Licensing Committee (“RMLC”), which represents over ten thousand commercial radio stations. On November 18, 2016, RMLC filed a complaint against GMR in the United States District Court for the Eastern District of Pennsylvania alleging that GMR is violating Section 2 of the Sherman Antitrust Act and seeking an injunction, requiring, among other things, that GMR issue radio stations licenses for GMR’s repertory, upon request, at a rate set through a judicial rate-making procedure, that GMR offer “economically viable alternatives to blanket licenses,” and that GMR offer only licenses for songs which are fully controlled by GMR. GMR and RLMC agreed to an interim license arrangement through September 30, 2017, which has been extended through March 31, 2018. GMR has advised the Company that it believes that the RMLC Complaint is without merit and is vigorously defending itself. On January 20, 2017, GMR filed a motion to dismiss or to transfer venue, asserting that the Eastern District of Pennsylvania is not a proper venue for the matter, lacks personal jurisdiction of GMR and that in any event the complaint fails to state a claim. On December 6, 2016, GMR filed a complaint against RMLC in the United States District Court for the Central District of California, alleging that RMLC operates as an illegal cartel that unreasonably restrains trade in violation of Section 1 of the Sherman Antitrust Act and California state law, and seeking an injunction restraining RMLC and its co-conspirators from enforcing or establishing agreements that unreasonably restrict competition for public performance licenses. The judge in the Central District of California denied RMLC’s motion to dismiss GMR’s claim for lack of ripeness and, on the basis that the two cases involve similar facts, stayed the California action in order to assess the status of the Pennsylvania case. On July 21, 2017, RMLC filed a preliminary injunction motion in the United States District Court for the Eastern District of Pennsylvania to extend the duration of the interim licenses which GMR had granted to certain radio stations. The district court determined that the jurisdictional matter should be decided prior to addressing the motion for preliminary injunction and referred the jurisdictional questions to the Magistrate Judge in the United States District Court Eastern District of Pennsylvania. On November 29, 2017, the Magistrate Judge issued a report and recommendation that personal jurisdiction was not appropriate over GMR in the Eastern District of Pennsylvania and recommending the dismissal of the RMLC’s action without prejudice. The RMLC has filed objections to the Magistrate Judge’s report and recommendation. The Company is a defendant in various other lawsuits. Although the outcome of these other lawsuits cannot be predicted with certainty (including the extent of available insurance, if any), management does not believe that resolution of these other lawsuits will have a material adverse effect on the Company.

Fair Value Measurements [Text Block]	Fair Value Measurements The following table presents the Company’s assets that are measured at fair value on a recurring basis, which include cash equivalents and available-for-sale securities: Fair Value Hierarchy December 31, June 30, Assets: Commercial Paper I $ 105,307 $ 105,476 Money market accounts I 174,774 102,884 Time deposits I 811,450 1,007,302 Available-for-sale securities I 24,638 32,851 Total assets measured at fair value $ 1,116,169 $ 1,248,513 All assets listed above are classified within Level I of the fair value hierarchy as they are valued using observable inputs that reflect quoted prices for identical assets in active markets. The carrying amounts of the Company’s commercial paper, money market accounts and time deposits approximate fair value due to their short-term maturities. The carrying value and fair value of the Company’s financial instruments reported in the accompanying consolidated balance sheets are as follows: December 31, 2017 June 30, 2017 Carrying Value Fair Value Carrying Fair Assets Notes receivable, including interest accruals $ 4,114 $ 4,114 $ 2,610 $ 2,610 Available-for-sale securities (a) 24,638 24,638 32,851 32,851 Liabilities Long-term debt, including current portion (b) $ 110,000 $ 108,826 $ 110,000 $ 110,091 _________________ (a) Aggregate cost basis for available-for-sale securities, including transaction costs, was $23,222 as of December 31, 2017 . The unrealized gain recorded in accumulated other comprehensive loss was $1,416 as of December 31, 2017 . The fair value of the available-for-sale securities is determined based on quoted market prices in an active market at the New York Stock Exchange, which is classified within Level I of the fair value hierarchy. (b) On January 31, 2017, TAO Group Intermediate Holdings LLC (“ TAOIH ”), TAO Group Operating LLC (“ TAOG ”) and certain of its subsidiaries entered into a $110,000 senior secured five -year term loan facility. The Company’s long-term debt is classified within Level II of the fair value hierarchy as it is valued using quoted indices of similar securities for which the inputs are readily observable. Contingent Consideration Liabilities In connection with the TAO Group acquisition (see Note 3 to the consolidated and combined financial statements included in the Company’s Annual Report on Form 10-K for the year ended June 30, 2017 for further details), the Company recorded certain contingent consideration liabilities at fair value as part of the preliminary purchase price allocation. The fair value was estimated using a Monte-Carlo simulation model which included significant unobservable Level III inputs such as projected financial performance over the earn-out period ( five years ) along with estimates for market volatility and the discount rate applicable to potential cash payouts. As of December 31, 2017 and June 30, 2017 , the fair value of contingent consideration liabilities in connection with the TAO Group acquisition was $7,900 . In connection with the CLG acquisition, the Company may be required to make future payments for deferred and contingent consideration up to a total of $9,150 based upon the achievement of certain specified objectives during the three years following the transaction as defined under the membership interest purchase agreement. The Company recorded $6,586 as the initial fair value of deferred and contingent consideration liabilities as part of the preliminary purchase price allocation. The fair values of these deferred and contingent consideration liabilities were estimated using weighted probabilities of achievement for the possible objective and earn-out events and adjusted for a discount rate applicable to the deferred and potential cash payouts. During the six months ended December 31, 2017 , the Company made a payment of $4,000 as one of the objectives for contingent consideration was achieved. As of December 31, 2017 , the fair value of deferred and contingent consideration liabilities was $2,586 .

Disclosure of Compensation Related Costs, Share-based Payments [Abstract]
Share-based Compensation [Text Block]	Share-based Compensation See Note 12 to the consolidated and combined financial statements included in the Company’s Annual Report on Form 10-K for the year ended June 30, 2017 for more information regarding the Company’s 2015 Employee Stock Plan (the “ Employee Stock Plan ”) and its 2015 Stock Plan for Non-Employee Directors. For the three months ended December 31, 2017 and 2016 , share-based compensation expense was recognized in the consolidated statements of operations as a component of direct operating expenses or selling, general and administrative expenses and was $13,912 and $11,743 , respectively. For the six months ended December 31, 2017 and 2016 , share-based compensation expense was $26,816 and $20,098 , respectively. Upon the adoption of ASU No. 2016-09, the Company elected to account for forfeitures as they occur on a prospective basis effective July 1, 2017, rather than estimating expected forfeitures as was required under the prior guidance. See “Note 2 . Accounting Policies — Recently Issued Accounting Pronouncements ” for further discussion on the impact from the adoption of ASU 2016-09. In addition, for the Company’s stock option awards, the Company applies the fair value recognition provisions of ASC Topic 718 “ Compensation — Stock Compensation ”. ASC Topic 718 requires companies to estimate the fair value of share-based payment awards on the date of grant using an option-pricing model. The Company determines the fair value as of the grant date. For awards with graded vesting conditions, the values of the awards are determined by valuing all vesting tranches in the aggregate as one award using an average expected term. For stock options, the Black-Scholes option pricing model considers, among other factors, the expected life of the award and the expected volatility of the Company’s stock price. The Company determines its assumptions for the Black-Scholes option-pricing model in accordance with ASC Topic 718 and SEC Staff Accounting Bulletin (“SAB”) No. 107, “ Share-Based Payment ” based on the following: • The expected term of stock options is estimated using the simplified method. • The expected risk-free interest rate is based on the U.S. Treasury interest rate which term is consistent with the expected term of the stock options. • The expected volatility is based on the historical volatility of the Company’s stock price. In December 2007, the SEC staff issued SAB No. 110, “ Certain Assumptions Used In Valuation Methods — Expected Term ”. SAB No. 110 allows companies to continue to use the simplified method, as defined in SAB No. 107, to estimate the expected term of stock options under certain circumstances. The simplified method for estimating expected term uses the mid-point between the vesting term and the contractual term of the stock option. The Company has analyzed the circumstances in which the use of the simplified method is allowed. The Company has opted to use the simplified method for stock options the Company granted in fiscal year 2018 because management believes that the Company does not have sufficient historical exercise data to provide a reasonable basis upon which to estimate the expected term. Restricted Stock Units Award Activity The following table summarizes activity related to holders (including the Company’s and MSG Networks’ employees) of the Company’s restricted stock units and performance restricted stock units, collectively referred to as “ RSUs ,” for the six months ended December 31, 2017 : Number of Weighted-Average Fair Value Per Share At Date of Grant Nonperformance Based Vesting RSUs Performance Based Vesting Unvested award balance, June 30, 2017 208 464 $ 172.78 Granted 103 180 $ 211.15 Vested (88 ) (249 ) $ 176.90 Forfeited (8 ) (127 ) $ 183.20 Unvested award balance, December 31, 2017 215 268 $ 189.51 The fair value of RSUs that vested during the six months ended December 31, 2017 was $74,582 . RSUs granted under the Employee Stock Plan were net share-settled to cover the required statutory tax withholding obligations. To fulfill the employees’ statutory minimum tax withholding obligations for the applicable income and other employment taxes, 57 of these RSUs , with an aggregate value of $12,232 were retained by the Company and reflected as financing activity in the accompanying consolidated statement of cash flows for the six months ended December 31, 2017 . The fair value of RSUs that vested during the six months ended December 31, 2016 was $15,209 . The weighted-average fair value per share at grant date of RSUs granted during the six months ended December 31, 2016 was $170.98 .

The maximum contractual term is 10 years. The Company calculated the fair value of these options on the date of grant using the Black-Scholes option pricing model, which resulted in a weighted-average grant-date fair value of $53.29 . The following are key assumptions used to calculate the weighted-average grant-date fair value of stock options: Expected term 6 years Expected volatility 20.38 % Risk-free interest rate 2.22 %

Income Tax Disclosure [Abstract]
Income Taxes [Text Block]	Income Taxes On December 22, 2017, new tax legislation, commonly referred to as the Tax Cuts and Jobs Act, was enacted, which significantly changed the existing U.S. tax laws, including a reduction in the corporate Federal income tax rate from 35% to 21% effective January 1, 2018. The Company is required to recognize the effect of tax law changes in the period of enactment even though certain key aspects of the new law became effective January 1, 2018. The Company’s income tax provision for interim periods is comprised of the tax on ordinary income (loss) provided at the most recent estimated annual effective tax rate, adjusted for the tax effect of discrete items. The Company used a blended statutory Federal income rate of 28% based upon the number of days that it will be taxed at the former rate of 35% and the number of days it will be taxed at the new rate of 21% to calculate its most recent estimated annual effective tax rate. Income tax expense (benefit) for the three months ended December 31, 2017 and 2016 was $(116,832) and $3,248 , respectively. For the six months ended December 31, 2017 and 2016 , income tax expense (benefit) was $(116,070) and $314 , respectively. Income tax benefit for the three months ended December 31, 2017 of $116,832 differs from the income tax expense derived from applying the blended statutory Federal rate of 28% to pretax income primarily as a result of a deferred income tax benefit of $113,494 related to the revaluation of the Company’s deferred tax assets and liabilities under provisions contained in the new tax legislation, of which (i) $51,015 was due to the reduction of net deferred tax liabilities in connection with the lower Federal income tax rate of 21%, and (ii) $62,479 was due to a reduction in the valuation allowance attributable to the new rules, which provide that future Federal net operating losses have an unlimited carry-forward period. These rules on future Federal net operating losses allow the Company to recognize a portion of its unrecognized deferred tax assets for future deductible items. Other decreases to the statutory rate include the impact of an income tax benefit of $27,059 in Federal and state valuation allowance decreases recorded which offsets the income tax expense attributable to most of the operating income, and the impact of a change in state tax rate of $3,241 . These decreases were partially offset by the impact of state and local income taxes (net of Federal benefit) of $6,494 and tax expense of $430 primarily related to non-deductible expenses. Income tax benefit for the six months ended December 31, 2017 of $116,070 differs from the income tax expense derived from applying the blended statutory Federal rate of 28% to pretax income primarily as a result of a deferred income tax benefit of $113,494 related to the revaluation of the Company’s deferred tax assets and liabilities under provisions contained in the new tax legislation, of which (i) $51,015 was due to the reduction of net deferred tax liabilities in connection with the lower Federal income tax rate of 21%, and (ii) $62,479 was due to a reduction in the valuation allowance attributable to the new rules, which provide that future Federal net operating losses have an unlimited carry-forward period. These rules on future Federal net operating losses allow the Company to recognize a portion of its unrecognized deferred tax assets for future deductible items. Other decreases to the statutory rate include the impact of an income tax benefit of $24,399 in Federal and state valuation allowance decreases recorded which offsets the income tax expense attributable to most of the operating income, and the impact of a change in state tax rate of $3,110 . These decreases were partially offset by the impact of state and local income taxes (net of Federal benefit) of $6,494 and tax expense of $1,237 primarily related to non-deductible expenses. Income tax expense for the three months ended December 31, 2016 of $3,248 differs from income tax expense derived from applying the statutory Federal rate of 35% to pretax income primarily as a result of a reduction of $22,123 of recorded Federal and state valuation allowances which offsets tax expense that would otherwise have been recorded on operating income. The tax expense also includes $3,126 to reverse a tax benefit recorded on operating losses in the three months ended September 30, 2016, as well as tax expense of $1,012 primarily related to non-deductible expenses. Income tax expense for the six months ended December 31, 2016 of $314 differs from income tax expense derived from applying the statutory Federal rate of 35% to pretax income primarily as a result of a reduction of $11,115 of recorded Federal and state valuation allowances which offsets tax expense that would have otherwise been recorded on operating income. The income tax expense also reflects tax expense of $1,342 primarily related to non-deductible expenses. The Company has not recorded any unrecognized tax benefits for uncertain tax positions as of December 31, 2017 and June 30, 2017 . The Company’s policy is to reflect interest and penalties associated with uncertain tax positions, if any, as a component of income tax expense.

Segment Information [Abstract]
Segment Information [Text Block]	Segment Information The Company is comprised of two reportable segments: MSG Entertainment and MSG Sports. In determining its reportable segments, the Company assessed the guidance of FASB ASC 280-10-50-1, which provides the definition of a reportable segment. In accordance with the FASB guidance, the Company takes into account whether two or more operating segments can be aggregated together as one reportable segment as well as the type of discrete financial information that is available and regularly reviewed by its chief operating decision maker. The Company has evaluated this guidance and determined that there are two reportable segments. The Company allocates certain corporate costs and its performance venue operating expenses to each of its reportable segments. Allocated venue operating expenses include the non-event related costs of operating the Company’s venues, and include such costs as rent for the Company’s leased venues, real estate taxes, insurance, utilities, repairs and maintenance, and labor related to the overall management of the venues. Depreciation and amortization expense related to The Garden , The Theater at Madison Square Garden, the Forum, and certain corporate property, equipment and leasehold improvements not allocated to the reportable segments is reported in “ Corporate and Other .” Additionally, the Company does not allocate any purchase accounting adjustments to the reporting segments. The Company evaluates segment performance based on several factors, of which the key financial measure is their operating income (loss) before (i) depreciation, amortization and impairments of property and equipment and intangible assets, (ii) share-based compensation expense or benefit, (iii) restructuring charges or credits, and (iv) gains or losses on sales or dispositions of businesses, which is referred to as adjusted operating income (loss) , a non-GAAP measure. In addition to excluding the impact of the items discussed above, the impact of purchase accounting adjustments related to business acquisitions is also excluded in evaluating the Company’s consolidated adjusted operating income (loss) . The Company believes adjusted operating income (loss) is an appropriate measure for evaluating the operating performance of its business segments and the Company on a consolidated basis. Adjusted operating income (loss) and similar measures with similar titles are common performance measures used by investors and analysts to analyze the Company’s performance. The Company uses revenues and adjusted operating income (loss) measures as the most important indicators of its business performance, and evaluates management’s effectiveness with specific reference to these indicators. Adjusted operating income (loss) should be viewed as a supplement to and not a substitute for operating income (loss), net income (loss), cash flows from operating activities, and other measures of performance and/or liquidity presented in accordance with GAAP. The Company has presented the components that reconcile operating income (loss), the most directly comparable GAAP financial measure, to adjusted operating income (loss) . Information as to the operations of the Company’s reportable segments is set forth below.

Accounting Policies [Abstract]
Principles of Consolidation	Principles of Consolidation The consolidated financial statements of the Company include the accounts of The Madison Square Garden Company and its subsidiaries. All significant intercompany transactions and balances have been eliminated in consolidation. In addition, the consolidated financial statements of the Company include the accounts from TAO Group , BCE and CLG , in which the Company has controlling voting interests. The Company’s consolidation criteria are based on authoritative accounting guidance for voting interest, controlling interest or variable interest entities. TAO Group , BCE and CLG are consolidated with the equity owned by other shareholders shown as redeemable or nonredeemable noncontrolling interests in the accompanying consolidated balance sheet s, and the other shareholders’ portion of net earnings (loss) and other comprehensive income (loss) shown as net income (loss) or comprehensive income (loss) attributable to redeemable or nonredeemable noncontrolling interests in the accompanying consolidated statements of operation s and consolidated statements of comprehensive income , respectively. See Note 2 to the consolidated and combined financial statements included in the Company’s Annual Report on Form 10-K for the year ended June 30, 2017 for more information regarding the classification of redeemable noncontrolling interests of TAO Group . In addition, TAO Group ’s results are reported on a three-month lag basis and TAO Group reports on a fiscal year reflecting the retail-based calendar (containing 4-4-5 week calendar quarters). Accordingly, the Company’s results for the three and six months ended December 31, 2017 include TAO Group ’s operating results from June 26, 2017 to September 24, 2017 and March 27, 2017 to September 24, 2017 , respectively.
Use of Estimates	Use of Estimates The preparation of the accompanying Financial Statements in conformity with GAAP requires management to make estimates and assumptions about future events. These estimates and the underlying assumptions affect the amount of assets and liabilities reported, disclosures about contingent assets and liabilities, and reported amounts of revenues and expenses. Such estimates include the valuation of accounts receivable, investments, goodwill, intangible assets, other long-lived assets, tax accruals and other liabilities. In addition, estimates are used in revenue recognition, revenue sharing expense (net of escrow), luxury tax expense, income tax expense, performance and share-based compensation, depreciation and amortization, litigation matters and other matters, as well as in the valuation of contingent consideration and noncontrolling interests resulting from business combination transactions. Management believes its use of estimates in the Financial Statements are reasonable. Management evaluates its estimates on an ongoing basis using historical experience and other factors, including the general economic environment and actions it may take in the future. The Company adjusts such estimates when facts and circumstances dictate. However, these estimates may involve significant uncertainties and judgments and cannot be determined with precision. In addition, these estimates are based on management’s best judgment at a point in time and, as such, these estimates may ultimately differ from actual results. Changes in estimates resulting from weakness in the economic environment or other factors beyond the Company’s control could be material and would be reflected in the Company’s financial statements in future periods.
Revenue Recognition	Revenue Recognition Deferred revenue reported in the accompanying consolidated balance sheets as of December 31, 2017 and June 30, 2017 includes amounts due to the third-party promoters of $50,414 and $72,400 , respectively.
Foreign Currency Transactions	Foreign Currency Translation The consolidated financial statements are presented in U.S. Dollars. Assets and liabilities of non-U.S. subsidiaries that operate in a local currency environment, where that local currency is the functional currency, are translated to U.S. Dollars at exchange rates in effect at the balance sheet date. Operating results of non-U.S. subsidiaries are translated at weighted-average exchange rates during the year which approximate the rates in effect at the transaction dates. Foreign currency translation gains and losses are included as a component of accumulated other comprehensive income (loss) as changes in cumulative translation adjustments in the accompanying consolidated balance sheet.
Recently Issued Accounting Pronouncements	Recently Issued Accounting Pronouncements Recently Adopted Accounting Pronouncements In March 2016, the Financial Accounting Standards Board (“ FASB ”) issued Accounting Standards Update (“ ASU ”) No. 2016-07, Investments - Equity Method and Joint Ventures (Topic 323), Simplifying the Transition to the Equity Method of Accounting . ASU No. 2016-07 eliminates the requirement for an investor to retrospectively apply the equity method when an investment that it had accounted for by another method qualifies for use of the equity method. This standard was adopted by the Company prospectively in the first quarter of fiscal year 2018. The adoption of the standard did not have an impact on the Company’s consolidated financial statements. In March 2016, the FASB issued ASU No. 2016-09, Compensation - Stock Compensation (Topic 718): Improvements to Employee Share-based Payment Accounting . ASU No. 2016-09, among other things, (i) requires the income tax effects of all awards to be recognized in the statement of operations when the awards vest or are settled, (ii) allows an employer to repurchase more of an employee’s shares for tax withholding purposes than currently allowable, without triggering liability accounting, and provides companies with the option to make a policy election to account for forfeitures as they occur, and (iii) requires companies to present excess tax benefits as operating activity rather than as financing activity on the statement of cash flows. This standard was adopted by the Company in the first quarter of fiscal year 2018. In connection with the Company’s election to record forfeitures as they occur, the Company used the modified retrospective transition method and recorded a cumulative effect of $2,403 , which was an increase in beginning accumulated deficits with the offset by an equal increase in additional paid in capital. In addition, the Company prospectively adopted the provision regarding the presentation of excess tax benefits in the statement of cash flows, which did not result in a change in the net cash provided by operating activities for the six months ended December 31, 2017 because the Company currently maintains a 100% valuation allowance on its deferred tax asset. In May 2017, the FASB issued ASU No. 2017-09, Compensation - Stock Compensation (Topic 718): Scope of Modification Accounting. ASU No. 2017-09 provides clarification on when modification accounting should be used for changes to the terms or conditions of a share-based payment award. This standard does not change the accounting for modifications but clarifies that modification accounting guidance should only be applied if there is a change to the value, vesting conditions or award classification and would not be required if the changes are considered non-substantive. This standard was early adopted by the Company prospectively in the first quarter of fiscal year 2018. The adoption of the standard did not have an impact on the Company’s consolidated financial statements. Recently Issued Accounting Pronouncements Not Yet Adopted In May 2014, the FASB issued ASU No. 2014-09, Revenue from Contracts with Customers ( Topic 606 ) , which supersedes the revenue recognition requirements in FASB Accounting Standards Codification (“ ASC ”) Topic 605, Revenue Recognition . ASC Topic 606 , among other things, (i) is based on the principle that revenue is recognized to depict the transfer of goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange f or those goods or services, and (ii) requires additional disclosure about the nature, amount, timing and uncertainty of revenue and cash flows arising from customer contracts, including significant judgments and changes in judgments and assets recognized from costs incurred to obtain or fulfill a contract. In August 2015, the FASB issued ASU No. 2015-14 , Revenue from Contracts with Customers (Topic 606) : Deferral of the Effective Date , which defers the effective date of ASU No. 2014-09 for all entities by one year. In March 2016, the FASB issued ASU No. 2016-08, Revenue from Contracts with Customers (Topic 606), Principal versus Agent Considerations (Reporting Revenue versus Net) , which clarifies the implementation guidance on principal versus agent considerations in the new revenue recognition standard under ASU No. 2014-09. ASU No. 2016-08 clarifies how an entity should identify the unit of accounting (i.e. the specified good or service) for the principal versus agent evaluation and how it should apply the control principle to certain types of arrangements. In April 2016, the FASB issued ASU No. 2016-10, Revenue from Contracts with Customers (Topic 606): Identifying Performance Obligations and Licensing , which clarifies the principle in ASU No 2014-09 for determining whether a good or service is separately identifiable from other promises in the contract and, therefore, should be accounted for separately. ASU No. 2016-10 also clarifies that entities are not required to identify promised goods or services that are immaterial in the context of the contract and allows entities to elect to account for shipping and handling activities as a fulfillment cost rather than as an additional promised service. In May 2016, the FASB issued ASU No. 2016-12, Revenue from Contracts with Customers (Topic 606) - Narrow-Scope Improvements and Practical Expedients , which clarifies the following aspects in ASU No. 2014-09: collectability, presentation of sales taxes and other similar taxes collected from customers, noncash considerations, contract modifications at transition, completed contracts at transition, and technical correction. In December, the FASB issued ASU No. 2016-20, Technical Corrections and Improvements to Topic 606, Revenue from Contracts with Customers , which allows entities not to make quantitative disclosures about remaining performance obligations in certain cases and requires entities that use any of the new or previously existing optional exemptions to expand their qualitative disclosures. ASC Topic 606 and the related updates will be effective for the Company beginning in the first quarter of fiscal year 2019 using one of two retrospective application methods. The Company’s evaluation of the impact this standard will have on its consolidated financial statements is ongoing. Based on the review to date, the Company believes that the adoption of the new standard will impact the quarterly and annual recognition for certain revenue streams. While the Company has made substantial progress in concluding the appropriate treatment for most of its revenue streams, the review is ongoing for a few remaining revenue streams. The Company has not decided whether the retrospective or modified retrospective method will be used in adopting the new standard. In January 2016, the FASB issued ASU No. 2016-01, Financial Instruments - Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities, addresses certain aspects of recognition, measurement, presentation, and disclosure of financial instruments. This standard, among other things, (i) requires equity investments, with certain exceptions, to be measured at fair value with changes in fair value recognized in net income and (ii) simplifies the impairment assessment of equity investments without readily determinable fair values by requiring a qualitative assessment to identify impairment. Early adoption is not permitted with the exception of certain provisions related to the presentation of other comprehensive income. This standard will be effective for the Company beginning in the first quarter of fiscal year 2019. The Company is currently evaluating the impact this standard will have on its consolidated financial statements. In February 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842) , which supersedes existing guidance on accounting for leases in FASB ASC Topic 840, Leases . ASU No. 2016-02, among other things, (i) requires lessees to account for leases as either finance leases or operating leases and generally requires all leases to be recorded on the balance sheet, including those leases classified as operating leases under previous accounting guidance, through the recognition of right-of-use assets and corresponding lease liabilities, and (ii) requires extensive qualitative and quantitative disclosures about leasing activities. The accounting applied by a lessor is largely unchanged from that applied under previous accounting guidance. This standard will be effective for the Company beginning in the first quarter of fiscal year 2020 and is required to be applied using the modified retrospective approach for all leases existing as of the effective date. Early adoption is permitted; however, the Company currently does not plan to adopt this standard early. The Company’s evaluation of the impact this standard will have on its consolidated financial statements is ongoing. Based on efforts to date, the adoption of the standard will result in the recognition of right of use assets and lease liabilities related to the Company’s operating leases. In June 2016, the FASB issued ASU 2016-13, Financial Instruments - Credit Losses . ASU 2016-13 replaces the incurred loss impairment methodology in current U.S. GAAP with a methodology that will require the reflection of expected credit losses and will also require consideration of a broader range of reasonable and supportable information to determine credit loss estimates. For most financial instruments, the standard will require the use of a forward-looking expected loss model rather than the incurred loss model for recognizing credit losses, which will generally result in the earlier recognition of credit losses on financial instruments. This standard will be effective for the Company beginning in the first quarter of fiscal year 2021, with early adoption permitted. The Company is currently evaluating the impact this standard will have on its consolidated financial statements. In August 2016, the FASB issued ASU No. 2016-15, Statement of Cash Flows (Topic 230). ASU No. 2016-15 addresses eight specific cash flow issues and is intended to reduce diversity in practice in how certain cash receipts and cash payments are presented and classified in the statement of cash flows. This standard will be effective for the Company beginning in the first quarter of fiscal year 2019. Early adoption is permitted. The adoption of this standard is not expected to have a material impact on the Company’s consolidated financial statements. In October 2016, the FASB issued ASU No. 2016-16, Income Taxes (Topic 740): Intra-Entity Transfers of Assets Other Than Inventory . ASU No. 2016-16 requires entities to recognize income tax consequences of an intra-entity transfer of an asset other than inventory when the transfer occurs. This standard will be effective for the Company beginning in the first quarter of fiscal year 2019. Early adoption is permitted as of the beginning of an annual reporting period for which financial statements have not been issued or made available for issuance. The adoption of this standard is not expected to have a material impact on the Company’s consolidated financial statements. In November 2016, the FASB issued ASU No. 2016-18, Statement of Cash Flows: Restricted Cash . The primary purpose of ASU No. 2016-18 is to reduce the diversity in practice that exists in the classification and presentation of changes in restricted cash on the statement of cash flows. This standard will require that a statement of cash flows explain the change during the period in the total of cash, cash equivalents, and amounts generally described as restricted cash or restricted cash equivalents. Therefore, amounts generally described as restricted cash and restricted cash equivalents should be included with cash and cash equivalents when reconciling the beginning-of-period and end-of-period total amounts shown on the statement of cash flows. This standard will be effective retrospectively for the Company beginning in the first quarter of fiscal year 2019, and will result in a change to the Company’s presentation of net cash provided by (used in) operating activities in the statement of cash flows for the impact of changes in restricted cash balances. Early adoption is permitted in any interim or annual period. In January 2017, the FASB issued ASU No. 2017-01, Business Combinations (Topic 805) Clarifying the Definition of a Business . The primary purpose of this ASU is to clarify the definition of a business with the objective of adding guidance to assist entities with evaluating whether transactions should be accounted for as acquisitions (or disposals) of assets or businesses, which will affect many areas of accounting including acquisitions, disposals, goodwill, and consolidation. This standard will be effective for the Company beginning in the first quarter of fiscal year 2019 and is required to be applied prospectively. Early adoption is permitted. The adoption of this standard is not expected to have a material impact on the Company’s consolidated financial statements. In January 2017, the FASB issued ASU No. 2017-04, Intangibles - Goodwill and Other (Topic 350): Simplifying the Accounting for Goodwill Impairment. ASU No. 2017-04 removes Step 2 of the goodwill impairment test, which requires a hypothetical purchase price allocation. A goodwill impairment will now be the amount by which a reporting unit’s carrying value exceeds its fair value, not to exceed the carrying amount of goodwill. This standard will be effective for the Company beginning in the first quarter of fiscal year 2021 and is required to be applied prospectively. Early adoption is permitted for interim or annual goodwill impairment tests performed on testing dates after January 1, 2017. The adoption of this standard is not expected to have a material impact on the Company’s consolidated financial statements. In March 2017, the FASB issued ASU No. 2017-07, Compensation - Retirement Benefits (Topic 715): Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost. ASU No. 2017-07 requires employers to disaggregate the service cost component from the other components of net benefit cost and disclose by line item the amount of net benefit cost that is included in the statement of operations or capitalized in assets. The standard requires employers to report the service cost component in the same line item(s) as other compensation costs arising from services rendered by the pertinent employees during the period and to report other components of net benefit cost separately and outside the subtotal of operating income. The standard also allows only the service cost component to be eligible for capitalization. This standard will be effective for the Company beginning in the first quarter of fiscal year 2019. The guidance requires application on a retrospective basis for the presentation of the service cost component and the other components of net benefit cost in the statements of operations and on a prospective basis for the capitalization of the service cost component of net benefit cost in assets. Early adoption is permitted as of the beginning of an annual reporting period for which financial statements have not been issued or made available for issuance. For the three months ended December 31, 2017 , net periodic pension and other postretirement employee benefit cost reported within operating income totaled to $1,031 , of which $53 represented service cost. For the six months ended December 31, 2017 , net periodic pension and other postretirement employee benefit cost reported within operating income totaled to $2,093 , of which $105 represented service cost.

Share-based Compensation, Option and Incentive Plans Policy [Policy Text Block]	In addition, for the Company’s stock option awards, the Company applies the fair value recognition provisions of ASC Topic 718 “ Compensation — Stock Compensation ”. ASC Topic 718 requires companies to estimate the fair value of share-based payment awards on the date of grant using an option-pricing model. The Company determines the fair value as of the grant date. For awards with graded vesting conditions, the values of the awards are determined by valuing all vesting tranches in the aggregate as one award using an average expected term. For stock options, the Black-Scholes option pricing model considers, among other factors, the expected life of the award and the expected volatility of the Company’s stock price. The Company determines its assumptions for the Black-Scholes option-pricing model in accordance with ASC Topic 718 and SEC Staff Accounting Bulletin (“SAB”) No. 107, “ Share-Based Payment ” based on the following: • The expected term of stock options is estimated using the simplified method. • The expected risk-free interest rate is based on the U.S. Treasury interest rate which term is consistent with the expected term of the stock options. • The expected volatility is based on the historical volatility of the Company’s stock price. In December 2007, the SEC staff issued SAB No. 110, “ Certain Assumptions Used In Valuation Methods — Expected Term ”. SAB No. 110 allows companies to continue to use the simplified method, as defined in SAB No. 107, to estimate the expected term of stock options under certain circumstances. The simplified method for estimating expected term uses the mid-point between the vesting term and the contractual term of the stock option. The Company has analyzed the circumstances in which the use of the simplified method is allowed. The Company has opted to use the simplified method for stock options the Company granted in fiscal year 2018 because management believes that the Company does not have sufficient historical exercise data to provide a reasonable basis upon which to estimate the expected term.
