BCE produces New England’s premier live music festival, Boston Calling Music Festival. The MSG Entertainment segment also includes the Company’s original production — the Christmas Spectacular Starring the Radio City Rockettes (the “ Christmas 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 Hartford Wolf Pack of the American Hockey League (the “ AHL ”) and the Westchester Knicks of the NBA G League (the “ NBAGL ”). The professional sports franchises are collectively referred to herein as “ the sports teams .” For all periods presented, MSG Sports also included the New York Liberty (the “Liberty”) of the Women’s National Basketball Association (the “WNBA”), which was sold in January 2019. 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 addition, the MSG Sports segment includes Counter Logic Gaming (“ CLG ”), a premier North American esports organization, which the Company acquired in July 2017, and Knicks Gaming , the Company’s franchise that competes in the NBA 2K League. CLG and Knicks Gaming are collectively referred to herein as “ the esports teams ,” and together with the sports teams , “ the teams .” 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 Hulu 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. Additionally, TAO Group operates various restaurants, nightlife and hospitality venues under long-term leases and management contracts in New York, Las Vegas, Los Angeles, Chicago, 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 “ 2015 Distribution ”), which occurred on September 30, 2015. See Note 1 to the consolidated financial statements included in the Company’s Annual Report on Form 10-K for the year ended June 30, 2018 for more information regarding the 2015 Distribution to its common stockholders. Potential Spin-off Transaction On June 27, 2018, the Company announced that its board of directors (“ Board ”) has authorized the Company’s management to explore a possible spin-off that would create a separately-traded public company comprised of its sports businesses, including the New York Knicks and New York Rangers professional sports franchises (the “ Sports Distribution ”). On October 4, 2018, in connection with the Sports Distribution , a subsidiary of the Company submitted an initial Registration Statement on Form 10 with the U.S. Securities and Exchange Commission (“ SEC ”) (which has been amended). If the Company proceeds with the Sports Distribution , it would be structured as a tax-free transaction to the Company’s stockholders. Upon completion of the contemplated separation, record holders of the Company’s common stock would receive a pro-rata distribution, expected to be equivalent, in the aggregate, to an approximately two-thirds economic interest in the sports company. The remaining common stock, expected to be equivalent to an approximately one-third economic interest in the sports company, would be retained by the Company. There can be no assurance that the proposed transaction will be completed in the manner described above, or at all. The Company’s management is working to complete the proposed transaction in the second half of calendar year 2019. Completion of the transaction would be subject to various conditions, including certain league approvals, a private letter ruling from the Internal Revenue Service (“ IRS ”), receipt of a tax opinion from counsel and final Board approval. The Company will maintain the current operating structure and will continue to report the financial results of its sports business in continuing operations until the Sports Distribution is completed. 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, 2018 (“ fiscal year 2018 ”). 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 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. 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. This impact has become more significant as a result of the adoption of ASC Topic 606 (as defined below). Reclassifications Certain reclassifications have been made in order to conform to the current period’s presentation. The reclassifications primarily relate to: (i) the presentation in the consolidated statement of cash flows for the prior year period in connection with the adoption of Accounting Standards Update (“ ASU ”) No. 2016-18, Statement of Cash Flows: Restricted Cash, (ii) the presentation of the non-service cost components of net periodic pension and postretirement benefit cost in the consolidated statement of operations for the prior year period in connection with the adoption of ASU No. 2017-07, Compensation - Retirement Benefits (Topic 715): Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost, (iii) segregation of amounts due to promoters from deferred revenue in connection with the adoption of Accounting Standards Codification (“ASC”) Topic 606, Revenue from Contracts with Customers (Topic 606) (referred to herein as “ASC Topic 606”), and (iv) an indefinite-lived intangible asset that was previously reported under other assets .

Accounting Policies [Abstract]
Accounting Policies [Text Block]	Accounting Policies 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 (loss) , respectively. See Note 2 to the consolidated financial statements included in the Company’s Annual Report on Form 10-K for the year ended June 30, 2018 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 calendar that ends on the last Sunday of the calendar year (containing 4-4-5 week calendar quarters). Accordingly, the Company’s results for the three months ended March 31, 2019 and 2018 include TAO Group ’s operating results for 13 weeks from October 1, 2018 to December 30, 2018 and for 14 weeks from September 25, 2017 to December 31, 2017 , respectively. The Company’s results for the nine months ended March 31, 2019 and 2018 include TAO Group ’s operating results for 39 weeks from April 2, 2018 to December 30, 2018 and for 40 weeks from March 27, 2017 to December 31, 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, income tax, 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, 2018 : Revenue Recognition Amounts due to third-party promoters of $89,513 , which were previously reported as Deferred revenue in the accompanying consolidated balance sheet as of June 30, 2018 , are now reported as Collections due to promoters in the accompanying consolidated balance sheet. In addition, see Recently Adopted Accounting Pronouncements below for disclosure related to the transitional impact of adopting ASC Topic 606 and Note 3 for other disclosure required under ASC Topic 606. Short-term investments Short-term investments consist of investments that (i) have original maturities of greater than three months and (ii) the Company expects to convert into cash within one year. The Company currently has a pound-denominated time deposit that has an original maturity date of six months from inception. The Company classified this investment at the time of purchase as “held-to-maturity” and re-evaluates its classification quarterly based on whether the Company has the intent and ability to hold until maturity. This investment, which is recorded at cost and adjusted for accrued interest, approximates fair value. Cash inflows and outflows related to the sale and purchase of short-term investments are classified as investing activities in the Company's consolidated statements of cash flows. Recently Issued Accounting Pronouncements Recently Adopted Accounting Pronouncements In May 2014 , the Financial Accounting Standards Board (“ FASB ”) issued ASU No. 2014-09, Revenue from Contracts with Customers (Topic 606) , which supersedes the revenue recognition requirements in ASC Topic 605, Revenue Recognition . Subsequently, the FASB issued various updates related to ASC Topic 606 including: (i) ASU No. 2015-14 , Revenue from Contracts with Customers (Topic 606) : Deferral of the Effective Date, (ii) ASU No. 2016-08, Revenue from Contracts with Customers (Topic 606), Principal versus Agent Considerations (Reporting Revenue versus Net), (iii) ASU No. 2016-10, Revenue from Contracts with Customers (Topic 606): Identifying Performance Obligations and Licensing, (iv) ASU No. 2016-12, Revenue from Contracts with Customers (Topic 606) - Narrow-Scope Improvements and Practical Expedients, and (v) ASU No. 2016-20, Technical Corrections and Improvements to Topic 606, Revenue from Contracts with Customers. The Company adopted ASC Topic 606 in the first quarter of fiscal year 2019 using the modified retrospective method for those contracts with customers which were not completed as of July 1, 2018. Results for reporting periods beginning after July 1, 2018 are presented under ASC Topic 606, while prior period amounts are not adjusted and continue to be reported in accordance with the historic accounting guidance under ASC Topic 605. As a result of the adoption of ASC Topic 606, the Company now accounts for its performance obligations under suite license arrangements as a series and as a result, the related suite license fees for all years during the license term are aggregated for each license agreement and revenue is recognized proportionately when the underlying events at The Garden take place, as opposed to previously being recognized on a straight-line basis over the fiscal year under the prior standard. In addition, the majority of the Company’s local media rights revenue is now recognized over the course of the teams’ regular seasons, which reflects the Company’s progress towards satisfaction of its performance obligations under such arrangements, as opposed to previously being recognized on a straight-line basis over the fiscal year under the prior standard. The Company also enters into arrangements with multiple performance obligations, such as multi-year sponsorship agreements. To the extent these arrangements provide for performance obligations that are consistent over the multi-year contractual term, such performance obligations generally meet the definition of a series as provided for under the provisions of ASC Topic 606. As a result, the contractual fees for all years during the contract term are aggregated and the related revenue is recognized proportionately as the underlying performance obligations are satisfied. In general, sponsorship revenue was previously recognized by treating each year of the arrangement as a discrete contract year, and as such the stated contract price was recognized in each year. Furthermore, the timing of certain fulfillment costs associated with performance obligations, primarily professional sports teams’ operating expenses, were also similarly impacted within the fiscal year. The adoption of ASC Topic 606 had the following impact on revenues, operating expenses and operating income for the three and nine months ended March 31, 2019 : Three Months Ended March 31, 2019 As reported under Changes due to the adoption of ASC Topic 606 (a) Amounts without adoption Revenues $ 517,190 $ (41,392 ) $ 475,798 Operating expenses: Direct operating expenses 310,792 4,518 315,310 Selling, general and administrative expenses 138,949 — 138,949 Depreciation and amortization 28,936 — 28,936 Operating income (loss) $ 38,513 $ (45,910 ) $ (7,397 ) Nine Months Ended March 31, 2019 As reported under Changes due to the adoption of ASC Topic 606 (a) Amounts without adoption Revenues $ 1,367,512 $ (39,623 ) $ 1,327,889 Operating expenses: Direct operating expenses 821,510 2,182 823,692 Selling, general and administrative expenses 391,205 — 391,205 Depreciation and amortization 88,792 — 88,792 Operating income $ 66,005 $ (41,805 ) $ 24,200 _________________ (a) See Note 18 for the impact of the adoption of ASC Topic 606 on the Company’s reportable segments results of operations. In accordance with the new revenue recognition standard disclosure requirements, the following tables summarize the impact of adopting ASC Topic 606 on the Company’s consolidated balance sheet as of July 1, 2018. Consolidated Balance Sheet As of July 1, 2018 Amounts without Changes due to Adjusted under ASSETS Current Assets: Other current assets $ 28,996 $ 4,366 $ 33,362 Total current assets 1,415,669 4,366 1,420,035 Total assets $ 3,736,173 $ 4,366 $ 3,740,539 LIABILITIES, REDEEMABLE NONCONTROLLING INTERESTS AND EQUITY Current Liabilities: Employee related costs $ 123,992 $ 79 $ 124,071 Other accrued liabilities 180,272 562 180,834 Deferred revenue 324,749 (30,480 ) 294,269 Total current liabilities 765,505 (29,839 ) 735,666 Total liabilities 1,105,454 (29,839 ) 1,075,615 The Madison Square Garden Company Stockholders’ Equity: Retained Earnings (Accumulated deficit) (11,059 ) 34,205 23,146 Total The Madison Square Garden Company stockholders’ equity 2,536,483 34,205 2,570,688 Total equity 2,554,035 34,205 2,588,240 Total liabilities, redeemable noncontrolling interests and equity $ 3,736,173 $ 4,366 $ 3,740,539 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, which 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. In February 2018, the FASB issued ASU No. 2018-03, Technical Corrections and Improvements to Financial Instruments Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities , which clarifies certain aspects of the guidance issued in ASU No. 2016-01. Among other things, the amendment clarifies that an entity that uses the measurement alternative for equity securities without readily determinable fair values can change its measurement approach to fair value. Once the election is made, the measurement approach is irrevocable and the entity is required to apply the selected approach to that security and all identical or similar investments of the same issuer. This change in accounting is expected to create greater volatility in the Company’s miscellaneous income (expense) in the future. The primary impact of the adoption of ASU No. 2016-01 and ASU No. 2018-03 relate to the Company’s available-for-sale equity investment and resulted in unrecognized gains and losses from such investment being reflected in the Company’s consolidated statements of operations beginning in fiscal year 2019. The Company adopted ASU No. 2016-01 and ASU No. 2018-03 in the first quarter of fiscal year 2019 and recorded a cumulative-effect adjustment to the balance sheet by reclassifying the balance of the Accumulated other comprehensive loss to Accumulated deficit of $5,570 including income tax expense effect of $3,104 . See Notes 7 and 10 for more information on the Company’s equity investment with readily determinable fair value in Townsquare Media, Inc. (“ Townsquare ”). 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 how certain cash receipts and cash payments are presented and classified in the statement of cash flows. The Company adopted this standard in the first quarter of fiscal year 2019 retrospectively. The adoption of this standard did not have an 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 the recognition of income tax consequences of an intra-entity transfer of an asset other than inventory when the transfer occurs. The Company adopted this standard in the first quarter of fiscal year 2019 on a modified retrospective basis. The adoption of this standard did not have an 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 diversity in the classification and presentation of changes in restricted cash on the statement of cash flows. This standard requires that a statement of cash flows explains the change during the period in total 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. The Company adopted this standard in the first quarter of fiscal year 2019 retrospectively and it resulted in a decrease to net cash flows provided by operating activities of $6,163 for the nine months ended March 31, 2018 . See Note 6 for a reconciliation of the cash, cash equivalents and restricted cash reported in the Company’s consolidated balance sheets to the amounts as reported on the consolidated statements of cash flows. 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. The Company adopted this standard in the first quarter of fiscal year 2019. The adoption of this standard did not have an 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. 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. The Company adopted this standard in the first quarter of fiscal year 2019 retrospectively and elected the practical expedient allowed by ASU No. 2017-07 to utilize amounts disclosed in the Company’s pension plans and other postretirement benefit plan (see Note 12 ) for the prior comparative period as the estimation basis for applying the retrospective presentation requirements. As a result, the Company recorded a prior period adjustment in the accompanying consolidated statements of operations for the three months ended March 31, 2018 to decrease Direct operating expenses and Selling, general and administrative expenses by $286 and $707 , respectively, which was related to the non-service cost components of net periodic pension and postretirement benefit cost , with a corresponding adjustment of $993 in Miscellaneous income (expense), net . For the nine months ended March 31, 2018 , the Company recorded a prior period adjustment in the accompanying consolidated statements of operations to decrease Direct operating expenses and Selling, general and administrative expenses by $809 and $2,172 , respectively, which was related to the non-service cost components of net periodic pension and postretirement benefit cost , with a corresponding adjustment of $2,981 in Miscellaneous income (expense), net . For the three and nine months ended March 31, 2019 , the non-service cost components of net periodic pension and postretirement benefit cost included under Miscellaneous income (expense), net in the accompanying consolidated statements of operations was $1,077 and $3,228 , respectively. In June 2018, the FASB issued ASU No. 2018-07, Compensation — Stock Compensation (Topic 718): Improvements to Nonemployee Share-Based Payment Accounting , which expands the scope of ASC Topic 718 to include all share-based payment transactions for acquiring goods and services from nonemployees. ASU No. 2018-07 specifies that ASC Topic 718 applies to all share-based payment transactions in which the grantor acquires goods and services to be used or consumed in its own operations by issuing share-based payment awards. ASU No. 2018-07 also clarifies that ASC Topic 718 does not apply to share-based payments used to effectively provide (i) financing to the issuer or (ii) awards granted in conjunction with selling goods or services to customers as part of a contract accounted for under ASC Topic 606. The Company early adopted this standard in the third quarter of fiscal year 2019. The adoption of this standard did not have an impact on the Company’s consolidated financial statements. Recently Issued Accounting Pronouncements Not Yet Adopted In February 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842) , which supersedes existing guidance on accounting for leases in 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. In January 2018, the FASB issued ASU No. 2018-01, Leases (Topic 842) — Land Easement Practical Expedient for Transition to Topic 842 , which provides a lessee or lessor the option to not assess at transition whether existing land easements, not currently accounted for as leases under the current lease guidance, should be treated as leases under the new standard. In July 2018, the FASB issued ASU No. 2018-10, Codification Improvements to Topic 842, Leases and ASU No. 2018-11, Leases (Topic 842) Targeted improvements , which provides an additional (and optional) transition method whereby the new lease standard is applied at the adoption date and recognized as an adjustment to retained earnings. The effective date and transition requirements for ASU No. 2018-01, ASU No. 2018-10 and ASU No. 2018-11 are the same as ASU No. 2016-02. This standard, as amended, 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. The Company plans to adopt this standard using the optional transition method allowed by ASU No. 2018-11, whereby the Company will initially apply the new leases standard at July 1, 2019, and will recognize a cumulative-effect adjustment to the opening balance of retained earnings in the period of adoption. 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 No. 2016-13, Financial Instruments — Credit Losses . ASU No. 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 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 August 2018, the FASB issued ASU No. 2018-13, Fair Value Measurement (Topic 820): Disclosure Framework — Changes to the Disclosure Requirements for Fair Value Measurement as part of the FASB’s broader disclosure framework project. ASU No. 2018-13 removes, modifies and adds certain disclosures providing greater focus on requirements that clearly communicate the most important information to the users of the financial statements with respect to fair value measurements. The standard is effective for the Company beginning in the first quarter of fiscal year 2021, with early adoption permitted. Most of the disclosure requirements in ASU No. 2018-13 would need to be applied on a retrospective basis except for the guidance related to (i) unrealized gains and loss included in other comprehensive income, (ii) disclosure related to range and weighted average Level 3 unobservable inputs and (iii) narrative disclosure requirements on measurement uncertainty, which are required to be applied on a prospective basis. The Company is currently evaluating the impact this standard will have on its consolidated financial statements. In August 2018, the FASB issued ASU No. 2018-14, Compensation-Retirement Benefits-Defined Benefit Plans — General (Subtopic 715-20): Disclosure Framework-Changes to the Disclosure Requirements for Defined Benefit Plans . ASU No. 2018-14 removes certain disclosures that are not considered cost beneficial, clarifies certain required disclosures and adds additional disclosures. The standard will be effective for the Company in the fourth quarter of fiscal year 2021, with early adoption permitted. The amendments in ASU No. 2018-14 are required to be applied retrospectively. The Company is currently evaluating the impact this standard will have on its consolidated financial statements. In August 2018, the FASB issued ASU No. 2018-15, Intangibles — Goodwill and Other-Internal-Use Software (Subtopic 350-40): Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That is a Service Contract . ASU No. 2018-15 aligns the requirements for capitalizing implementation costs incurred in a hosting arrangement that is a service contract with the requirements for capitalizing implementation costs incurred to develop or obtain internal-use software. The guidance also specifies that the balance sheet, income statement, and statement of cash flows presentation of capitalized implementation costs and the related amortization should align with the presentation of the hosting (service) element of the arrangement. The standard is effective for the Company in the first quarter of fiscal year 2021, with early adoption permitted. Entities have the option to apply the guidance prospectively to all implementation costs incurred after the date of adoption or retrospectively. The adoption of this standard is not expected to have a material impact on the Company’s consolidated financial statements. In November 2018, the FASB issued ASU No. 2018-17, Targeted Improvements to Related Party Guidance for Variable Interest Entities . ASU No. 2018-17 amends the variable interest entities (“VIE”) guidance to align the evaluation of a decision maker’s or service provider’s fee in assessing a variable interest with the guidance in the primary beneficiary test. Specifically, indirect interests held by a related party that is under common control will now be considered on a proportionate basis, rather than in their entirety, when assessing whether the fee qualifies as a variable interest. The proportionate basis approach is consistent with the treatment of indirect interests held by a related party under common control when evaluating the primary beneficiary of a VIE. This effectively means that when a decision maker or service provider has an interest in a related party, regardless of whether they are under common control, it will consider that related party's interest in a VIE on a proportionate basis throughout the VIE model, for both the assessment of a variable interest and the determination of a primary beneficiary. The standard will be effective for the Company in the first quarter of fiscal year 2021, with early adoption permitted. The amendments in ASU No. 2018-17 are required to be applied retrospectively. The Company is currently evaluating the impact this standard will have on its consolidated financial statements. In November 2018, the FASB issued ASU No. 2018-18, Collaborative Arrangements (Topic 808): Clarifying the Interaction between Topic 808 and Topic 606. ASU No. 2018-18 clarifies that certain transactions between participants in a collaborative arrangement should be accounted for under ASC Topic 606 when the counterparty is a customer. In addition, ASU No. 2018-18 precludes an entity from presenting consideration from a transaction in a collaborative arrangement as revenue from contracts with customers if the counterparty is not a customer for that transaction. The standard will be effective for the Company in the first quarter of fiscal year 2021, with early adoption permitted. The amendments in ASU No. 2018-18 are required to be applied retrospectively to the date when the Company initially adopted ASC Topic 606 . The Company is currently evaluating the impact this standard will have on its consolidated financial statements.

Revenue Recognition [Abstract]
Revenue from Contract with Customer [Text Block]	Revenue Recognition Contracts with Customers All revenue recognized in the consolidated statements of operations is considered to be revenue from contracts with customers in accordance with ASC Topic 606. For the three and nine months ended March 31, 2019 , the Company did not have any impairment losses on receivables or contract assets arising from contracts with customers. The Company recognizes revenue when, or as, performance obligations under the terms of a contract are satisfied, which generally occurs when, or as, control of promised goods or services are transferred to customers. Revenue is measured as the amount that reflects the consideration the Company expects to be entitled to in exchange for those goods or services (“transaction price”). To the extent the transaction price includes variable consideration, the Company estimates the amount of variable consideration that should be included in the transaction price utilizing the most likely amount to which the Company expects to be entitled. Variable consideration is included in the transaction price if, in the Company’s judgment, it is probable that a significant future reversal of cumulative revenue under the contract will not occur. Estimates of variable consideration and the determination of whether to include such estimated amounts in the transaction price are based largely on an assessment of the Company’s anticipated performance and all information that is reasonably available. The Company accounts for taxes collected from customers and remitted to governmental authorities on a net basis and excludes these amounts from revenues. In addition, the Company defers certain costs to fulfill the Company’s contracts with customers to the extent such costs relate directly to the contracts, are expected to generate resources that will be used to satisfy the Company’s performance obligations under the contracts and are expected to be recovered through revenue generated under the contracts. Contract fulfillment costs are expensed as the Company satisfies the related performance obligations. Arrangements with Multiple Performance Obligations The Company has arrangements with multiple performance obligations, such as multi-year sponsorship agreements which may derive revenues for each of the Company’s segments within a single arrangement. Payment terms for such arrangements can vary by contract, but payments are generally due in installments throughout the contractual term. The performance obligations included in each sponsorship agreement vary and may include various advertising benefits such as, but not limited to, signage at The Garden and the Company’s other venues, digital advertising, event or property specific advertising, as well as non-advertising benefits such as suite licenses and event tickets. To the extent the Company’s multi-year arrangements provide for performance obligations that are consistent over the multi-year contractual term, such performance obligations generally meet the definition of a series as provided for under the accounting guidance. If performance obligations are concluded to meet the definition of a series, the contractual fees for all years during the contract term are aggregated and the related revenue is recognized proportionately as the underlying performance obligations are satisfied. The timing of revenue recognition for each performance obligation is dependent upon the facts and circumstances surrounding the Company’s satisfaction of its respective performance obligation. The Company allocates the transaction price for such arrangements to each performance obligation within the arrangement based on the estimated relative standalone selling price of the performance obligation. The Company’s process for determining its estimated standalone selling prices involves management’s judgment and considers multiple factors including company specific and market specific factors that may vary depending upon the unique facts and circumstances related to each performance obligation. Key factors considered by the Company in developing an estimated standalone selling price for its performance obligations include, but are not limited to, prices charged for similar performance obligations, the Company’s ongoing pricing strategy and policies, and consideration of pricing of similar performance obligations sold in other arrangements with multiple performance obligations. The Company may incur costs such as commissions to obtain its multi-year sponsorship agreements. The Company assesses such costs for capitalization on a contract by contract basis. To the extent costs are capitalized, the Company estimates the useful life of the related contract asset which may be the underlying contract term or the estimated customer life depending on the facts and circumstances surrounding the contract. The contract asset is amortized over the estimated useful life. Principal versus Agent Revenue Recognition The Company reports revenue on a gross or net basis based on management’s assessment of whether the Company acts as a principal or agent in the transaction. The determination of whether the Company acts as a principal or an agent in a transaction is based on an evaluation of whether the Company controls the good or service before transfer to the customer. When the Company concludes that it controls the good or service before transfer to the customer, the Company is considered a principal in the transaction and records revenue on a gross basis. When the Company concludes that it does not control the good or service before transfer to the customer but arranges for another entity to provide the good or service, the Company acts as an agent and records revenue on a net basis in the amount it earns for its agency service. In connection with the 2015 Distribution , the Company entered into an advertising sales representation agreement with MSG Networks. Pursuant to the agreement, the Company has the exclusive right and obligation to sell advertising on behalf of MSG Networks. The Company is entitled to and earns commission revenue as the advertisements are aired on MSG Networks. Since the Company acts as an agent, the Company recognizes the advertising commission revenue on a net basis. The Company’s revenue recognition policies that summarize the nature, amount, timing and uncertainty associated with each of the Company’s revenue sources are discussed further in each respective segment discussion below. MSG Entertainment The Company’s MSG Entertainment segment earns event related revenues principally from the sale of tickets for events that the Company produces or promotes/co-promotes, and from venue license fees charged to third-party promoters for events held at the Company’s venues that MSG Entertainment does not produce or promote/co-promote. The Company’s performance obligations with respect to event-related revenues from the sale of tickets, venue license fees from third-party promoters, sponsorships, concessions and merchandise are satisfied at the point of sale or as the related event occurs. MSG Entertainment’s revenues also include revenue from the license of The Garden’s suites. Suite license arrangements are generally multi-year fixed-fee arrangements that include annual fee increases. Payment terms for suite license arrangements can vary by contract, but payments are generally due in installments prior to each license year. The Company’s performance obligation under such arrangements is to provide the licensee with access to the suite when events occur at The Garden. The Company accounts for the performance obligation under these types of arrangements as a series and, as a result, the related suite license fees for all years during the license term are aggregated and revenue is recognized proportionately over the license period as the Company satisfies the related performance obligation. Progress toward satisfaction of the Company’s annual suite license performance obligations is measured as access to the suite is provided to the licensee for each event throughout the contractual term of the license. The Company’s MSG Entertainment segment also earns revenues from the sale of advertising in the form of venue signage and other forms of sponsorship, which are not related to any specific event. The Company’s performance obligations with respect to this advertising are satisfied as the related benefits are delivered over the term of the respective agreements. Revenues from dining, nightlife and hospitality offerings through TAO Group are recognized when food, beverages and/or services are provided to the customer as that is the point in which the related performance obligation is satisfied. In addition, management fee revenues which are earned in accordance with specific venue management agreements are recorded over the period in which the management services are performed as such depicts the measure of progress toward satisfaction of the Company’s venue management performance obligations. Amounts collected in advance of the Company’s satisfaction of its contractual performance obligations are recorded as a contract liability within deferred revenue and are recognized as the Company satisfies the related performance obligations. Amounts collected in advance of events for which the Company is not the promoter or co-promoter do not represent contract liabilities and are recorded as collections due to promoters on the balance sheet. MSG Sports The Company’s professional sports teams derive event-related revenues principally from ticket sales which are recognized as the related games occur. MSG Sports revenues also include revenue from the license of The Garden’s suites. Suite license arrangements are generally multi-year fixed fee arrangements that include annual fee increases. Payment terms for suite license arrangements can vary by contract, but payments are generally due in installments prior to each license year. The Company’s performance obligation under such arrangements is to provide the licensee with access to the suite when events occur at The Garden. The Company accounts for the performance obligation under these types of arrangements as a series and, as a result, the related suite license fees for all years during the license term are aggregated and revenue is recognized proportionately over the license period as the Company satisfies the related performance obligation. Progress toward satisfaction of the Company’s suite license performance obligations is measured as access to the suite is provided to the licensee for each event throughout the contractual term of the license. In addition to event-related revenue, MSG Sports maintains local media rights arrangements which provide for the licensing of team-related programming to MSG Networks. MSG Sports, pursuant to the terms of the agreements, receives such rights fees in equal monthly installments throughout each license year. The transaction price under these arrangements is variable in nature as certain credit provisions exist to the extent that the teams’ games are unavailable for broadcast during an individual league season. The Company estimates the transaction price at the beginning of each fiscal year, which coincides with the annual contractual term. In estimating the transaction price, the Company considers the contractually agreed upon license fees as well as qualitative considerations with respect to the number of games expected to be available for broadcast by MSG Networks over the upcoming year. The resulting transaction price is allocated entirely to the rights provided for the related contract year and revenue is recognized using an output measure of progress toward satisfaction of the Company’s performance obligations within the contract year, as the underlying benefits are conveyed to the licensee. The Company’s professional sports teams also derive revenue from the distribution of league-wide national and international television contracts and other league-wide revenue sources. The transaction price for each of these revenues is based upon the expected distribution values as communicated by the applicable league. The timing of revenue recognition is dependent on the nature of the underlying performance obligation, which is generally over time. Receipt of league-wide revenues generally occurs at the time of communication or according to a specified timeline. MSG Sports also earns revenues from the sale of advertising in the form of venue signage and sponsorships, which are not related to any specific event. The Company’s performance obligations with respect to this advertising are satisfied as the related benefits are delivered over the term of the respective agreements. The Company’s MSG Sports segment also derives revenue from live sporting events not related to the Company’s teams. The Company’s performance obligations with respect to event-related revenues from other live sporting events, including the sale of tickets, venue license fees earned in connection with other live sporting events that the Company does not produce or promote, sponsorships, concessions and merchandise are satisfied at the point of sale or as the related event occurs. Amounts collected in advance of the Company’s satisfaction of its contractual performance obligations are recorded as a contract liability within deferred revenue and are recognized as the Company satisfies the related performance obligations. Amounts collected in advance of events for which the Company is not the promoter or co-promoter do not represent contract liabilities and are recorded as collections due to promoters on the balance sheet. Disaggregation of Revenue The following table disaggregates the Company’s revenue by major source and reportable segment based upon the timing of transfer of goods or services to the customer for the three and nine months ended March 31, 2019 : Three Months Ended March 31, 2019 MSG MSG Eliminations Total Event-related (a) $ 144,459 $ 159,405 $ (685 ) $ 303,179 Sponsorship, signage and suite licenses 17,666 66,714 (171 ) 84,209 League distributions — 50,996 — 50,996 Local media rights fees from MSG Networks — 66,073 — 66,073 Other (b) 4,327 8,406 — 12,733 Total revenues from contracts with customers $ 166,452 $ 351,594 $ (856 ) $ 517,190 Nine Months Ended March 31, 2019 MSG MSG Eliminations Total Event-related (a) $ 564,244 $ 316,368 $ (685 ) $ 879,927 Sponsorship, signage and suite licenses 57,658 149,875 (511 ) 207,022 League distributions — 107,924 — 107,924 Local media rights fees from MSG Networks — 130,244 — 130,244 Other (b) 24,017 18,378 — 42,395 Total revenues from contracts with customers $ 645,919 $ 722,789 $ (1,196 ) $ 1,367,512 _________________ (a) Consists of (i) ticket sales and other ticket-related revenues, (ii) TAO Group’s entertainment dining and nightlife offerings, (iii) food, beverage and merchandise sales, and (iv ) venue license fees from third-party promoters.

Pursuant to the terms, the Tribeca Enterprises revolving credit facility will be terminated on June 30, 2021 . The loan outstanding include payments-in-kind (“ PIK ”) interest of $3,125 and $2,025 as of March 31, 2019 and June 30, 2018 , respectively. PIK interest owed does not reduce the availability under the revolving credit facility. The $17,500 Tribeca Enterprises revolving credit facility was fully drawn as of March 31, 2019 and June 30, 2018 . (b) In accordance with the ASU No. 2016-01 and ASU No. 2018-03, that were adopted on July 1, 2018, the cost method accounting for equity investments was eliminated. Such investments are required to be presented at fair value. The Company has elected to account for its equity securities without readily determinable fair values that are carried at cost, adjusted for impairment and changes resulting from observable price fluctuations in orderly transactions for the identical or a similar investment of the same issuer (“ Measurement Alternative ”). The Company applies the Measurement Alternative , which is classified within Level III of the fair value hierarchy, on its equity investments without readily determinable fair values as of March 31, 2019 and July 1, 2018 and did not identify any adjustments. On December 5, 2018 , the Company sold its 50% interest in AMSGE (renamed The Azoff Company ) joint venture for $125,000 to The Azoff Company Holdings (“ Azoff Music ”). The Company recorded a gain on the sale of its interest in AMSGE of $3,227 (net of transaction costs of $2,282 ), which is reported in Earnings (loss) in equity method investments in the accompanying consolidated statements of operations for the nine months ended March 31, 2019 . The $63,500 outstanding under the revolving credit facility previously extended by the Company to AMSGE was also converted to a subordinated term loan with a maturity date of September 20, 2021 . This subordinated term loan was assumed by The Azoff Company Equity LLC, a newly-formed holding company that owns, directly or indirectly, the investments previously owned by AMSGE. This subordinated term loan bears interest at a floating rate, which at the option of The Azoff Company Equity LLC, is either (i) a base rate plus a margin of 1.25% per annum or (ii) six-month LIBOR plus a margin of 2.25% per annum. Azoff Music directly or through its affiliates will continue to provide consulting services to the Company, including with respect to the Forum and other venues (including MSG Spheres). See Note 10 for more information on this subordinated term loan receivable.

The Company plans to utilize SACO as a preferred display technology provider for MSG Spheres and benefit from agreed upon commercial terms. The total consideration consisted of a $42,444 payment at closing and a $4,800 deferred payment, which was made in October 2018. As of the acquisition date, the carrying amount of the investment was greater than the Company’s equity interest in the underlying net assets of SACO . As such, the Company allocated the difference to amortizable intangible assets of $25,350 and is amortizing these intangible assets on a straight-line basis over the expected useful lives ranging from 6 to 12 years. Equity Investment with Readily Determinable Fair Value In addition to the investments discussed above, the Company holds an investment of 3,208 shares of the common stock of Townsquare . Townsquare is a leading media, entertainment and digital marketing solutions company that is listed on the New York Stock Exchange (“ NYSE ”) under the symbol “TSQ.” In accordance with ASC Topic 321, Investments - Equity Securities, this investment is measured at readily determinable fair value and is reported under Other assets in the accompanying consolidated balance sheet as of March 31, 2019 and June 30, 2018 .

Upon delivery, RSUs granted under the Employee Stock Plan were net share-settled to cover the required statutory tax withholding obligations. To fulfill the employees’ required statutory tax withholding obligations for the applicable income and other employment taxes, 64 of these RSUs , with an aggregate value of $19,525 were retained by the Company and the taxes paid are reflected as financing activity in the accompanying consolidated statement of cash flows for the nine months ended March 31, 2019 . The fair value of RSUs that vested during the nine months ended March 31, 2018 was $74,582 .

Stock Options Award Activity The following table summarizes activity related to the Company’s stock options for the nine months ended March 31, 2019 : Number of Time Vesting Options Weighted-Average Exercise Price Per Share Weighted-Average Remaining Contractual Term (In Years) Aggregate Intrinsic Value Balance as of June 30, 2018 94 $ 210.13 Granted 449 $ 349.57 Balance as of March 31, 2019 543 $ 325.47 7.31 $ 7,788 Exercisable as of March 31, 2019 31 $ 210.13 8.72 $ 2,596 During the nine months ended March 31, 2019 , the Company granted 449 stock options that consisted of market priced stock options and premium priced stock options. The exercise prices of the premium priced stock options were set at a 10% and a 25% premium from the closing stock price at the date of grant. These stock options vest ratably over four years and are being expensed on a straight-line basis over the vesting period. The maximum contractual term is 7.5 years . The Company calculated the fair value of the market priced options on the date of grant using the Black-Scholes option pricing model and the premium priced options using the Monte Carlo Simulation. The following are key assumptions used to calculate the weighted-average grant-date fair value of the stock options: Market Price 10% Premium 25% Premium Weighted-average grant date fair value $ 79.99 $ 69.33 $ 55.64 Expected term 4.98 years 5.10 years 5.29 years Expected volatility 22.11 % 22.11 % 22.11 % Risk-free interest rate 3.02 % 3.11 % 3.11 % The expected terms of the premium priced options were estimated using the simplified method but takes into account that the options are out-of-the-money at grant date and therefore likely to be exercised later. The risk-free interest rate for the premium priced options was determined using a 7.50 year rate, different from the 4.98 year rate used to determine the market priced stock options.

Income Tax Disclosure [Abstract]
Income Taxes [Text Block]	Income Taxes On December 22, 2017, the enactment of the Tax Cuts and Jobs Act (“ TCJA ”) significantly changed U.S. tax law and included a reduction in the corporate federal income tax rate from 35% to 21% effective January 1, 2018. Income tax expense for the three months ended March 31, 2019 of $11,253 differs from income tax expense derived from applying the statutory federal rate of 21% to pretax income primarily due to a decrease in valuation allowance of $7,654 , state income tax expense of $6,515 , tax expense of $256 relating to noncontrolling interest, and the impact of nondeductible expenses of $2,281 . Income tax expense for the nine months ended March 31, 2019 of $12,605 differs from income tax expense derived from applying the statutory federal rate of 21% to pretax income primarily due to a decrease in valuation allowance of $26,630 , state income tax expense of $14,062 , excess tax benefit on share-based payment awards of $5,793 , tax expense of $1,801 relating to noncontrolling interest, and tax expense of $8,665 relating to nondeductible expenses. For the fiscal year ended June 30, 2018, the Company used a blended statutory federal income rate of 28% based upon the number of days that it would be taxed at the former rate of 35% and the number of days it would be taxed at the new rate of 21%, effective January 1, 2018. Income tax expense for the three months ended March 31, 2018 of $652 differs from income tax expense derived from applying the blended statutory federal rate of 28% to pretax income primarily as a result of a decrease of $2,787 in recorded federal and state valuation allowances, which offsets tax expense that would otherwise have been recorded in operating income, as well as a tax benefit of $1,435 associated with the vesting of restricted stock units. These decreases were partially offset by the impact of state and local income taxes (net of federal benefit) of $870 , and tax expense of $1,298 primarily related to non-deductible expenses. Income tax benefit for the nine months ended March 31, 2018 of $115,418 differs from 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 $27,186 in Federal and state valuation allowance decreases recorded, which offsets the income tax expense attributable to most of the operating income, the impact of a change in state tax rates of $3,110 , and a tax benefit of $1,435 associated with the vesting of restricted stock units. These decreases were partially offset by the impact of state and local income taxes (net of federal benefit) of $7,365 , and tax expense of $2,535 primarily related to non-deductible expenses. The Company was notified during the third quarter of fiscal year 2018 that the IRS was commencing an audit of the federal income tax return for the year ended June 30, 2016

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 ASC 280-10-50-1, which provides the definition of a reportable segment. In accordance with the FASB’s 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 , Hulu 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 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) . Because it is based upon operating income (loss), adjusted operating income (loss) also excludes interest expense (including cash interest expense) and other non-operating income and expense items. Management believes that the exclusion of share-based compensation expense or benefit allows investors to better track the performance of the various operating units of the Company’s business without regard to the settlement of an obligation that is not expected to be made in cash. 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. Since adjusted operating income (loss) is not a measure of performance calculated in accordance with GAAP, this measure may not be comparable to similar measures with similar titles used by other companies. The Company has presented the components that reconcile operating income (loss), the most directly comparable GAAP financial measure, to adjusted operating income (loss) . In addition, the retrospective adoption of ASU No. 2017-07 resulted in an immaterial improvement in operating income (loss) and adjusted operating income (loss) for the three and nine months ended March 31, 2018 (see Note 2 for further detail). Information as to the operations of the Company’s reportable segments is set forth below.

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 (loss) , respectively. See Note 2 to the consolidated financial statements included in the Company’s Annual Report on Form 10-K for the year ended June 30, 2018 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 calendar that ends on the last Sunday of the calendar year (containing 4-4-5 week calendar quarters). Accordingly, the Company’s results for the three months ended March 31, 2019 and 2018 include TAO Group ’s operating results for 13 weeks from October 1, 2018 to December 30, 2018 and for 14 weeks from September 25, 2017 to December 31, 2017 , respectively. The Company’s results for the nine months ended March 31, 2019 and 2018 include TAO Group ’s operating results for 39 weeks from April 2, 2018 to December 30, 2018 and for 40 weeks from March 27, 2017 to December 31, 2017
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, income tax, 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.
Revenue Recognition	Revenue Recognition Amounts due to third-party promoters of $89,513 , which were previously reported as Deferred revenue in the accompanying consolidated balance sheet as of June 30, 2018 , are now reported as Collections due to promoters in the accompanying consolidated balance sheet. In addition, see Recently Adopted Accounting Pronouncements below for disclosure related to the transitional impact of adopting ASC Topic 606 and Note 3

Recently Issued Accounting Pronouncements	Recently Issued Accounting Pronouncements Recently Adopted Accounting Pronouncements In May 2014 , the Financial Accounting Standards Board (“ FASB ”) issued ASU No. 2014-09, Revenue from Contracts with Customers (Topic 606) , which supersedes the revenue recognition requirements in ASC Topic 605, Revenue Recognition . Subsequently, the FASB issued various updates related to ASC Topic 606 including: (i) ASU No. 2015-14 , Revenue from Contracts with Customers (Topic 606) : Deferral of the Effective Date, (ii) ASU No. 2016-08, Revenue from Contracts with Customers (Topic 606), Principal versus Agent Considerations (Reporting Revenue versus Net), (iii) ASU No. 2016-10, Revenue from Contracts with Customers (Topic 606): Identifying Performance Obligations and Licensing, (iv) ASU No. 2016-12, Revenue from Contracts with Customers (Topic 606) - Narrow-Scope Improvements and Practical Expedients, and (v) ASU No. 2016-20, Technical Corrections and Improvements to Topic 606, Revenue from Contracts with Customers. The Company adopted ASC Topic 606 in the first quarter of fiscal year 2019 using the modified retrospective method for those contracts with customers which were not completed as of July 1, 2018. Results for reporting periods beginning after July 1, 2018 are presented under ASC Topic 606, while prior period amounts are not adjusted and continue to be reported in accordance with the historic accounting guidance under ASC Topic 605. As a result of the adoption of ASC Topic 606, the Company now accounts for its performance obligations under suite license arrangements as a series and as a result, the related suite license fees for all years during the license term are aggregated for each license agreement and revenue is recognized proportionately when the underlying events at The Garden take place, as opposed to previously being recognized on a straight-line basis over the fiscal year under the prior standard. In addition, the majority of the Company’s local media rights revenue is now recognized over the course of the teams’ regular seasons, which reflects the Company’s progress towards satisfaction of its performance obligations under such arrangements, as opposed to previously being recognized on a straight-line basis over the fiscal year under the prior standard. The Company also enters into arrangements with multiple performance obligations, such as multi-year sponsorship agreements. To the extent these arrangements provide for performance obligations that are consistent over the multi-year contractual term, such performance obligations generally meet the definition of a series as provided for under the provisions of ASC Topic 606. As a result, the contractual fees for all years during the contract term are aggregated and the related revenue is recognized proportionately as the underlying performance obligations are satisfied. In general, sponsorship revenue was previously recognized by treating each year of the arrangement as a discrete contract year, and as such the stated contract price was recognized in each year. Furthermore, the timing of certain fulfillment costs associated with performance obligations, primarily professional sports teams’ operating expenses, were also similarly impacted within the fiscal year. The adoption of ASC Topic 606 had the following impact on revenues, operating expenses and operating income for the three and nine months ended March 31, 2019 : Three Months Ended March 31, 2019 As reported under Changes due to the adoption of ASC Topic 606 (a) Amounts without adoption Revenues $ 517,190 $ (41,392 ) $ 475,798 Operating expenses: Direct operating expenses 310,792 4,518 315,310 Selling, general and administrative expenses 138,949 — 138,949 Depreciation and amortization 28,936 — 28,936 Operating income (loss) $ 38,513 $ (45,910 ) $ (7,397 ) Nine Months Ended March 31, 2019 As reported under Changes due to the adoption of ASC Topic 606 (a) Amounts without adoption Revenues $ 1,367,512 $ (39,623 ) $ 1,327,889 Operating expenses: Direct operating expenses 821,510 2,182 823,692 Selling, general and administrative expenses 391,205 — 391,205 Depreciation and amortization 88,792 — 88,792 Operating income $ 66,005 $ (41,805 ) $ 24,200 _________________ (a) See Note 18 for the impact of the adoption of ASC Topic 606 on the Company’s reportable segments results of operations. In accordance with the new revenue recognition standard disclosure requirements, the following tables summarize the impact of adopting ASC Topic 606 on the Company’s consolidated balance sheet as of July 1, 2018. Consolidated Balance Sheet As of July 1, 2018 Amounts without Changes due to Adjusted under ASSETS Current Assets: Other current assets $ 28,996 $ 4,366 $ 33,362 Total current assets 1,415,669 4,366 1,420,035 Total assets $ 3,736,173 $ 4,366 $ 3,740,539 LIABILITIES, REDEEMABLE NONCONTROLLING INTERESTS AND EQUITY Current Liabilities: Employee related costs $ 123,992 $ 79 $ 124,071 Other accrued liabilities 180,272 562 180,834 Deferred revenue 324,749 (30,480 ) 294,269 Total current liabilities 765,505 (29,839 ) 735,666 Total liabilities 1,105,454 (29,839 ) 1,075,615 The Madison Square Garden Company Stockholders’ Equity: Retained Earnings (Accumulated deficit) (11,059 ) 34,205 23,146 Total The Madison Square Garden Company stockholders’ equity 2,536,483 34,205 2,570,688 Total equity 2,554,035 34,205 2,588,240 Total liabilities, redeemable noncontrolling interests and equity $ 3,736,173 $ 4,366 $ 3,740,539 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, which 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. In February 2018, the FASB issued ASU No. 2018-03, Technical Corrections and Improvements to Financial Instruments Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities , which clarifies certain aspects of the guidance issued in ASU No. 2016-01. Among other things, the amendment clarifies that an entity that uses the measurement alternative for equity securities without readily determinable fair values can change its measurement approach to fair value. Once the election is made, the measurement approach is irrevocable and the entity is required to apply the selected approach to that security and all identical or similar investments of the same issuer. This change in accounting is expected to create greater volatility in the Company’s miscellaneous income (expense) in the future. The primary impact of the adoption of ASU No. 2016-01 and ASU No. 2018-03 relate to the Company’s available-for-sale equity investment and resulted in unrecognized gains and losses from such investment being reflected in the Company’s consolidated statements of operations beginning in fiscal year 2019. The Company adopted ASU No. 2016-01 and ASU No. 2018-03 in the first quarter of fiscal year 2019 and recorded a cumulative-effect adjustment to the balance sheet by reclassifying the balance of the Accumulated other comprehensive loss to Accumulated deficit of $5,570 including income tax expense effect of $3,104 . See Notes 7 and 10 for more information on the Company’s equity investment with readily determinable fair value in Townsquare Media, Inc. (“ Townsquare ”). 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 how certain cash receipts and cash payments are presented and classified in the statement of cash flows. The Company adopted this standard in the first quarter of fiscal year 2019 retrospectively. The adoption of this standard did not have an 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 the recognition of income tax consequences of an intra-entity transfer of an asset other than inventory when the transfer occurs. The Company adopted this standard in the first quarter of fiscal year 2019 on a modified retrospective basis. The adoption of this standard did not have an 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 diversity in the classification and presentation of changes in restricted cash on the statement of cash flows. This standard requires that a statement of cash flows explains the change during the period in total 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. The Company adopted this standard in the first quarter of fiscal year 2019 retrospectively and it resulted in a decrease to net cash flows provided by operating activities of $6,163 for the nine months ended March 31, 2018 . See Note 6 for a reconciliation of the cash, cash equivalents and restricted cash reported in the Company’s consolidated balance sheets to the amounts as reported on the consolidated statements of cash flows. 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. The Company adopted this standard in the first quarter of fiscal year 2019. The adoption of this standard did not have an 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. 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. The Company adopted this standard in the first quarter of fiscal year 2019 retrospectively and elected the practical expedient allowed by ASU No. 2017-07 to utilize amounts disclosed in the Company’s pension plans and other postretirement benefit plan (see Note 12 ) for the prior comparative period as the estimation basis for applying the retrospective presentation requirements. As a result, the Company recorded a prior period adjustment in the accompanying consolidated statements of operations for the three months ended March 31, 2018 to decrease Direct operating expenses and Selling, general and administrative expenses by $286 and $707 , respectively, which was related to the non-service cost components of net periodic pension and postretirement benefit cost , with a corresponding adjustment of $993 in Miscellaneous income (expense), net . For the nine months ended March 31, 2018 , the Company recorded a prior period adjustment in the accompanying consolidated statements of operations to decrease Direct operating expenses and Selling, general and administrative expenses by $809 and $2,172 , respectively, which was related to the non-service cost components of net periodic pension and postretirement benefit cost , with a corresponding adjustment of $2,981 in Miscellaneous income (expense), net . For the three and nine months ended March 31, 2019 , the non-service cost components of net periodic pension and postretirement benefit cost included under Miscellaneous income (expense), net in the accompanying consolidated statements of operations was $1,077 and $3,228 , respectively. In June 2018, the FASB issued ASU No. 2018-07, Compensation — Stock Compensation (Topic 718): Improvements to Nonemployee Share-Based Payment Accounting , which expands the scope of ASC Topic 718 to include all share-based payment transactions for acquiring goods and services from nonemployees. ASU No. 2018-07 specifies that ASC Topic 718 applies to all share-based payment transactions in which the grantor acquires goods and services to be used or consumed in its own operations by issuing share-based payment awards. ASU No. 2018-07 also clarifies that ASC Topic 718 does not apply to share-based payments used to effectively provide (i) financing to the issuer or (ii) awards granted in conjunction with selling goods or services to customers as part of a contract accounted for under ASC Topic 606. The Company early adopted this standard in the third quarter of fiscal year 2019. The adoption of this standard did not have an impact on the Company’s consolidated financial statements. Recently Issued Accounting Pronouncements Not Yet Adopted In February 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842) , which supersedes existing guidance on accounting for leases in 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. In January 2018, the FASB issued ASU No. 2018-01, Leases (Topic 842) — Land Easement Practical Expedient for Transition to Topic 842 , which provides a lessee or lessor the option to not assess at transition whether existing land easements, not currently accounted for as leases under the current lease guidance, should be treated as leases under the new standard. In July 2018, the FASB issued ASU No. 2018-10, Codification Improvements to Topic 842, Leases and ASU No. 2018-11, Leases (Topic 842) Targeted improvements , which provides an additional (and optional) transition method whereby the new lease standard is applied at the adoption date and recognized as an adjustment to retained earnings. The effective date and transition requirements for ASU No. 2018-01, ASU No. 2018-10 and ASU No. 2018-11 are the same as ASU No. 2016-02. This standard, as amended, 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. The Company plans to adopt this standard using the optional transition method allowed by ASU No. 2018-11, whereby the Company will initially apply the new leases standard at July 1, 2019, and will recognize a cumulative-effect adjustment to the opening balance of retained earnings in the period of adoption. 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 No. 2016-13, Financial Instruments — Credit Losses . ASU No. 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 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 August 2018, the FASB issued ASU No. 2018-13, Fair Value Measurement (Topic 820): Disclosure Framework — Changes to the Disclosure Requirements for Fair Value Measurement as part of the FASB’s broader disclosure framework project. ASU No. 2018-13 removes, modifies and adds certain disclosures providing greater focus on requirements that clearly communicate the most important information to the users of the financial statements with respect to fair value measurements. The standard is effective for the Company beginning in the first quarter of fiscal year 2021, with early adoption permitted. Most of the disclosure requirements in ASU No. 2018-13 would need to be applied on a retrospective basis except for the guidance related to (i) unrealized gains and loss included in other comprehensive income, (ii) disclosure related to range and weighted average Level 3 unobservable inputs and (iii) narrative disclosure requirements on measurement uncertainty, which are required to be applied on a prospective basis. The Company is currently evaluating the impact this standard will have on its consolidated financial statements. In August 2018, the FASB issued ASU No. 2018-14, Compensation-Retirement Benefits-Defined Benefit Plans — General (Subtopic 715-20): Disclosure Framework-Changes to the Disclosure Requirements for Defined Benefit Plans . ASU No. 2018-14 removes certain disclosures that are not considered cost beneficial, clarifies certain required disclosures and adds additional disclosures. The standard will be effective for the Company in the fourth quarter of fiscal year 2021, with early adoption permitted. The amendments in ASU No. 2018-14 are required to be applied retrospectively. The Company is currently evaluating the impact this standard will have on its consolidated financial statements. In August 2018, the FASB issued ASU No. 2018-15, Intangibles — Goodwill and Other-Internal-Use Software (Subtopic 350-40): Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That is a Service Contract . ASU No. 2018-15 aligns the requirements for capitalizing implementation costs incurred in a hosting arrangement that is a service contract with the requirements for capitalizing implementation costs incurred to develop or obtain internal-use software. The guidance also specifies that the balance sheet, income statement, and statement of cash flows presentation of capitalized implementation costs and the related amortization should align with the presentation of the hosting (service) element of the arrangement. The standard is effective for the Company in the first quarter of fiscal year 2021, with early adoption permitted. Entities have the option to apply the guidance prospectively to all implementation costs incurred after the date of adoption or retrospectively. The adoption of this standard is not expected to have a material impact on the Company’s consolidated financial statements. In November 2018, the FASB issued ASU No. 2018-17, Targeted Improvements to Related Party Guidance for Variable Interest Entities . ASU No. 2018-17 amends the variable interest entities (“VIE”) guidance to align the evaluation of a decision maker’s or service provider’s fee in assessing a variable interest with the guidance in the primary beneficiary test. Specifically, indirect interests held by a related party that is under common control will now be considered on a proportionate basis, rather than in their entirety, when assessing whether the fee qualifies as a variable interest. The proportionate basis approach is consistent with the treatment of indirect interests held by a related party under common control when evaluating the primary beneficiary of a VIE. This effectively means that when a decision maker or service provider has an interest in a related party, regardless of whether they are under common control, it will consider that related party's interest in a VIE on a proportionate basis throughout the VIE model, for both the assessment of a variable interest and the determination of a primary beneficiary. The standard will be effective for the Company in the first quarter of fiscal year 2021, with early adoption permitted. The amendments in ASU No. 2018-17 are required to be applied retrospectively. The Company is currently evaluating the impact this standard will have on its consolidated financial statements. In November 2018, the FASB issued ASU No. 2018-18, Collaborative Arrangements (Topic 808): Clarifying the Interaction between Topic 808 and Topic 606. ASU No. 2018-18 clarifies that certain transactions between participants in a collaborative arrangement should be accounted for under ASC Topic 606 when the counterparty is a customer. In addition, ASU No. 2018-18 precludes an entity from presenting consideration from a transaction in a collaborative arrangement as revenue from contracts with customers if the counterparty is not a customer for that transaction. The standard will be effective for the Company in the first quarter of fiscal year 2021, with early adoption permitted. The amendments in ASU No. 2018-18 are required to be applied retrospectively to the date when the Company initially adopted ASC Topic 606 . The Company is currently evaluating the impact this standard will have on its consolidated financial statements. In April 2019, the FASB issued ASU No. 2019-04, Codification Improvements to Topic 326, Financial Instruments — Credit Losses, Topic 815, Derivatives and Hedging, and Topic 825 — Financial Instruments

Revenue Recognition (Policies)

Revenue Recognition (Policies)	9 Months Ended
	Mar. 31, 2019
Revenue Recognition [Abstract]
Revenue from Contract with Customer [Policy Text Block]	Contracts with Customers All revenue recognized in the consolidated statements of operations is considered to be revenue from contracts with customers in accordance with ASC Topic 606. For the three and nine months ended March 31, 2019 , the Company did not have any impairment losses on receivables or contract assets arising from contracts with customers. The Company recognizes revenue when, or as, performance obligations under the terms of a contract are satisfied, which generally occurs when, or as, control of promised goods or services are transferred to customers. Revenue is measured as the amount that reflects the consideration the Company expects to be entitled to in exchange for those goods or services (“transaction price”). To the extent the transaction price includes variable consideration, the Company estimates the amount of variable consideration that should be included in the transaction price utilizing the most likely amount to which the Company expects to be entitled. Variable consideration is included in the transaction price if, in the Company’s judgment, it is probable that a significant future reversal of cumulative revenue under the contract will not occur. Estimates of variable consideration and the determination of whether to include such estimated amounts in the transaction price are based largely on an assessment of the Company’s anticipated performance and all information that is reasonably available. The Company accounts for taxes collected from customers and remitted to governmental authorities on a net basis and excludes these amounts from revenues. In addition, the Company defers certain costs to fulfill the Company’s contracts with customers to the extent such costs relate directly to the contracts, are expected to generate resources that will be used to satisfy the Company’s performance obligations under the contracts and are expected to be recovered through revenue generated under the contracts. Contract fulfillment costs are expensed as the Company satisfies the related performance obligations. Arrangements with Multiple Performance Obligations The Company has arrangements with multiple performance obligations, such as multi-year sponsorship agreements which may derive revenues for each of the Company’s segments within a single arrangement. Payment terms for such arrangements can vary by contract, but payments are generally due in installments throughout the contractual term. The performance obligations included in each sponsorship agreement vary and may include various advertising benefits such as, but not limited to, signage at The Garden and the Company’s other venues, digital advertising, event or property specific advertising, as well as non-advertising benefits such as suite licenses and event tickets. To the extent the Company’s multi-year arrangements provide for performance obligations that are consistent over the multi-year contractual term, such performance obligations generally meet the definition of a series as provided for under the accounting guidance. If performance obligations are concluded to meet the definition of a series, the contractual fees for all years during the contract term are aggregated and the related revenue is recognized proportionately as the underlying performance obligations are satisfied. The timing of revenue recognition for each performance obligation is dependent upon the facts and circumstances surrounding the Company’s satisfaction of its respective performance obligation. The Company allocates the transaction price for such arrangements to each performance obligation within the arrangement based on the estimated relative standalone selling price of the performance obligation. The Company’s process for determining its estimated standalone selling prices involves management’s judgment and considers multiple factors including company specific and market specific factors that may vary depending upon the unique facts and circumstances related to each performance obligation. Key factors considered by the Company in developing an estimated standalone selling price for its performance obligations include, but are not limited to, prices charged for similar performance obligations, the Company’s ongoing pricing strategy and policies, and consideration of pricing of similar performance obligations sold in other arrangements with multiple performance obligations. The Company may incur costs such as commissions to obtain its multi-year sponsorship agreements. The Company assesses such costs for capitalization on a contract by contract basis. To the extent costs are capitalized, the Company estimates the useful life of the related contract asset which may be the underlying contract term or the estimated customer life depending on the facts and circumstances surrounding the contract. The contract asset is amortized over the estimated useful life. Principal versus Agent Revenue Recognition The Company reports revenue on a gross or net basis based on management’s assessment of whether the Company acts as a principal or agent in the transaction. The determination of whether the Company acts as a principal or an agent in a transaction is based on an evaluation of whether the Company controls the good or service before transfer to the customer. When the Company concludes that it controls the good or service before transfer to the customer, the Company is considered a principal in the transaction and records revenue on a gross basis. When the Company concludes that it does not control the good or service before transfer to the customer but arranges for another entity to provide the good or service, the Company acts as an agent and records revenue on a net basis in the amount it earns for its agency service. In connection with the 2015 Distribution , the Company entered into an advertising sales representation agreement with MSG Networks. Pursuant to the agreement, the Company has the exclusive right and obligation to sell advertising on behalf of MSG Networks. The Company is entitled to and earns commission revenue as the advertisements are aired on MSG Networks. Since the Company acts as an agent, the Company recognizes the advertising commission revenue on a net basis. The Company’s revenue recognition policies that summarize the nature, amount, timing and uncertainty associated with each of the Company’s revenue sources are discussed further in each respective segment discussion below. MSG Entertainment The Company’s MSG Entertainment segment earns event related revenues principally from the sale of tickets for events that the Company produces or promotes/co-promotes, and from venue license fees charged to third-party promoters for events held at the Company’s venues that MSG Entertainment does not produce or promote/co-promote. The Company’s performance obligations with respect to event-related revenues from the sale of tickets, venue license fees from third-party promoters, sponsorships, concessions and merchandise are satisfied at the point of sale or as the related event occurs. MSG Entertainment’s revenues also include revenue from the license of The Garden’s suites. Suite license arrangements are generally multi-year fixed-fee arrangements that include annual fee increases. Payment terms for suite license arrangements can vary by contract, but payments are generally due in installments prior to each license year. The Company’s performance obligation under such arrangements is to provide the licensee with access to the suite when events occur at The Garden. The Company accounts for the performance obligation under these types of arrangements as a series and, as a result, the related suite license fees for all years during the license term are aggregated and revenue is recognized proportionately over the license period as the Company satisfies the related performance obligation. Progress toward satisfaction of the Company’s annual suite license performance obligations is measured as access to the suite is provided to the licensee for each event throughout the contractual term of the license. The Company’s MSG Entertainment segment also earns revenues from the sale of advertising in the form of venue signage and other forms of sponsorship, which are not related to any specific event. The Company’s performance obligations with respect to this advertising are satisfied as the related benefits are delivered over the term of the respective agreements. Revenues from dining, nightlife and hospitality offerings through TAO Group are recognized when food, beverages and/or services are provided to the customer as that is the point in which the related performance obligation is satisfied. In addition, management fee revenues which are earned in accordance with specific venue management agreements are recorded over the period in which the management services are performed as such depicts the measure of progress toward satisfaction of the Company’s venue management performance obligations. Amounts collected in advance of the Company’s satisfaction of its contractual performance obligations are recorded as a contract liability within deferred revenue and are recognized as the Company satisfies the related performance obligations. Amounts collected in advance of events for which the Company is not the promoter or co-promoter do not represent contract liabilities and are recorded as collections due to promoters on the balance sheet. MSG Sports The Company’s professional sports teams derive event-related revenues principally from ticket sales which are recognized as the related games occur. MSG Sports revenues also include revenue from the license of The Garden’s suites. Suite license arrangements are generally multi-year fixed fee arrangements that include annual fee increases. Payment terms for suite license arrangements can vary by contract, but payments are generally due in installments prior to each license year. The Company’s performance obligation under such arrangements is to provide the licensee with access to the suite when events occur at The Garden. The Company accounts for the performance obligation under these types of arrangements as a series and, as a result, the related suite license fees for all years during the license term are aggregated and revenue is recognized proportionately over the license period as the Company satisfies the related performance obligation. Progress toward satisfaction of the Company’s suite license performance obligations is measured as access to the suite is provided to the licensee for each event throughout the contractual term of the license. In addition to event-related revenue, MSG Sports maintains local media rights arrangements which provide for the licensing of team-related programming to MSG Networks. MSG Sports, pursuant to the terms of the agreements, receives such rights fees in equal monthly installments throughout each license year. The transaction price under these arrangements is variable in nature as certain credit provisions exist to the extent that the teams’ games are unavailable for broadcast during an individual league season. The Company estimates the transaction price at the beginning of each fiscal year, which coincides with the annual contractual term. In estimating the transaction price, the Company considers the contractually agreed upon license fees as well as qualitative considerations with respect to the number of games expected to be available for broadcast by MSG Networks over the upcoming year. The resulting transaction price is allocated entirely to the rights provided for the related contract year and revenue is recognized using an output measure of progress toward satisfaction of the Company’s performance obligations within the contract year, as the underlying benefits are conveyed to the licensee. The Company’s professional sports teams also derive revenue from the distribution of league-wide national and international television contracts and other league-wide revenue sources. The transaction price for each of these revenues is based upon the expected distribution values as communicated by the applicable league. The timing of revenue recognition is dependent on the nature of the underlying performance obligation, which is generally over time. Receipt of league-wide revenues generally occurs at the time of communication or according to a specified timeline. MSG Sports also earns revenues from the sale of advertising in the form of venue signage and sponsorships, which are not related to any specific event. The Company’s performance obligations with respect to this advertising are satisfied as the related benefits are delivered over the term of the respective agreements. The Company’s MSG Sports segment also derives revenue from live sporting events not related to the Company’s teams. The Company’s performance obligations with respect to event-related revenues from other live sporting events, including the sale of tickets, venue license fees earned in connection with other live sporting events that the Company does not produce or promote, sponsorships, concessions and merchandise are satisfied at the point of sale or as the related event occurs.
