Description of Business and Basis of Presentation	NOTE 1. DESCRIPTION OF BUSINESS AND BASIS OF PRESENTATION Fox Corporation, a Delaware corporation (“FOX” or the “Company”), is a news, sports and entertainment company, which manages and reports its businesses in the following segments: Cable Network Programming, Television and Other, Corporate and Eliminations. The Distribution On March 19, 2019, the Company became a standalone publicly traded company through the pro rata distribution by Twenty-First Century Fox, Inc. (now known as TFCF Corporation) (“21CF”) of all of the issued and outstanding common stock of FOX to 21CF stockholders (other than holders that were subsidiaries of 21CF) (the “Distribution”) in accordance with the Amended and Restated Distribution Agreement and Plan of Merger, dated as of June 20, 2018, by and between 21CF and 21CF Distribution Merger Sub, Inc. Following the Distribution, 354,328,270 and 266,173,651 shares of the Company’s Class A Common Stock, par value $0.01 per share (the “Class A Common Stock”), and Class B Common Stock, par value $0.01 per share (the “Class B Common Stock” and, together with the Class A Common Stock, the “Common Stock”), respectively, began trading independently on The Nasdaq Global Select Market (“NASDAQ”). In connection with the Distribution, the Company entered into the Separation and Distribution Agreement, dated as of March 19, 2019 (the “Separation Agreement”), with 21CF, which effected the internal restructuring (the “Separation”) whereby 21CF transferred to FOX a portfolio of 21CF’s news, sports and broadcast businesses, including FOX News Media (consisting of FOX News and FOX Business), the FOX Network, FOX Sports, FOX Television Stations, and sports cable networks FS1, FS2, FOX Deportes and Big Ten Network (collectively, the “FOX business”), and certain other assets, and FOX assumed from 21CF the liabilities associated with such businesses and certain other liabilities. The Separation and the Distribution were effected as part of a series of transactions contemplated by the Amended and Restated Merger Agreement and Plan of Merger, dated as of June 20, 2018 (the “21CF Disney Merger Agreement”), by and among 21CF, The Walt Disney Company (“Disney”) and certain subsidiaries of Disney, pursuant to which, among other things, 21CF became a wholly-owned subsidiary of Disney. In connection with the Separation, the Company entered into several agreements that govern certain aspects of the Company’s relationship with 21CF and Disney following the Separation. These include the Separation Agreement, a tax matters agreement, a transition services agreement, as well as agreements relating to intellectual property licenses, employee matters, commercial arrangements and a studio lot lease. The Separation Agreement contains the key provisions relating to the Separation and the Distribution. The Separation Agreement identifies the assets that were transferred, the liabilities that were assumed and the contracts that were assigned to each of the Company and 21CF as part of the Separation and describes how these transfers, assumptions and assignments occurred. It also provides for cross-indemnities between the Company and 21CF. Other matters governed by the Separation Agreement include access to financial and other information, confidentiality, access to and provision of records, continued access for the Company to 21CF insurance policies and shared contracts and certain third-party consent provisions. Pursuant to the Separation Agreement, the Company is the owner of all “FOX” brands and related trademarks, as well as all other intellectual property primarily related to the Company’s business. In addition, the Company has entered into certain trademark and other intellectual property license agreements in connection with the use of certain intellectual property by 21CF. The Company also entered into a tax matters agreement with Disney and 21CF that governs the parties’ respective rights, responsibilities and obligations with respect to certain tax matters. Under the tax matters agreement, 21CF will generally indemnify the Company against any taxes required to be reported on a consolidated or separate tax return of 21CF and/or any of its subsidiaries, including any taxes resulting from the Separation and the Distribution, and the Company will generally indemnify 21CF against any taxes required to be reported on a separate tax return of the Company or any of its subsidiaries. The Company may also be responsible for certain taxes resulting from the anticipated divestitures by Disney of certain assets, primarily the FOX Sports Regional Sports Networks. The Transaction Tax (as defined below) included a prepayment of the Company’s share of the estimated tax liabilities resulting from the anticipated divestitures by Disney of these assets in the amount of approximately $700 million (which amount is subject to adjustment in the future, as described below). In addition, the Company and 21CF entered into a transition services agreement under which the Company and 21CF are providing specified services to each other on a transitional basis, including broadcast operations, sports production, information systems and technology, human resources services, finance and accounting, facilities and other corporate services. Generally, the term for the provision of services under the agreement extends for no longer than two years after the Separation, subject to certain rights of the parties to extend the term for an additional three months. To the extent transition services are utilized during the first two years after the Separation, the charges paid by the recipient for the services are generally limited to the cost of providing such services. The Company anticipates that it will generally be in a position to complete the transition of most services on or before the two-year anniversary of the Separation. The Company owns the FOX Studios Lot in Los Angeles, California and is responsible for the management of the lot, including servicing and managing the facility and managing and providing studio operation services, including production operations and post-production services, which until 2026 will predominantly be Disney productions. The Company leased office space on the FOX Studios Lot to 21CF for an initial term of seven years, subject to two five-year renewal options exercisable by 21CF. The Company also entered into an employee matters agreement with 21CF that governs the parties’ obligations with respect to certain employee-related liabilities and certain employee benefit plans, programs, policies and other related matters for employees of the Company (See Note 11—Equity-Based Compensation and Note 14—Pension and Other Postretirement Benefits). Basis of Presentation Prior to the Distribution, the Company’s combined financial statements were prepared on a standalone basis, derived from the consolidated financial statements and accounting records of 21CF. The Company’s financial statements as of June 30, 2018 and for the years ended June 30, 2018 and 2017 are presented on a combined basis as the Company was not a separate consolidated group prior to the Distribution. These financial statements reflect the combined historical results of operations, financial position and cash flows of 21CF’s domestic news, national sports and broadcast businesses and certain other assets and liabilities associated with such businesses. The Company became a separate consolidated group as a result of the Distribution, and the Company’s financial statements as of June 30, 2019 and for the year ended June 30, 2019 are presented on a consolidated basis. The Consolidated and Combined Statements of Operations include allocations for certain support functions that were provided on a centralized basis within 21CF prior to the Distribution and not recorded at the business unit level, such as certain expenses related to finance, legal, insurance, information technology, compliance and human resources management activities, among others. 21CF did not routinely allocate these costs to any of its business units. These expenses have been allocated to FOX on the basis of direct usage when identifiable, with the remainder allocated on a pro rata basis of combined revenues, headcount or other relevant measures. Management believes the assumptions underlying the Consolidated and Combined Financial Statements, including the assumptions regarding allocating general corporate expenses from 21CF, are reasonable. Nevertheless, the Consolidated and Combined Financial Statements may not include all of the actual expenses that would have been incurred by FOX and may not reflect FOX’s consolidated results of operations, financial position and cash flows had it been a standalone company during the entirety of the periods presented. Actual costs that would have been incurred if FOX had been a standalone company would depend on multiple factors, including organizational structure and strategic decisions made in various areas, including information technology and infrastructure. The Company’s Consolidated Balance Sheet as of June 30, 2019 consists of the Company’s consolidated balances subsequent to the Distribution. The Company’s Combined Balance Sheet as of June 30, 2018 consists of the combined balances of 21CF’s domestic news, national sports and broadcast businesses and certain other assets and liabilities associated with such businesses. The assets and liabilities have been reflected on a historical cost basis, as prior to the Distribution all of the assets and liabilities presented were wholly owned by 21CF and were transferred to the combined FOX group at a carry-over basis. For purposes of the Company’s financial statements for the periods prior to the Distribution, the income tax provision in the Consolidated and Combined Statements of Operations was calculated as if FOX filed a separate tax return and was operating as a standalone business. Therefore, cash tax payments and items of current and deferred taxes may not be reflective of FOX’s actual tax balances prior to or subsequent to the Distribution. Prior to the Distribution, the Company’s operating results were included in 21CF’s consolidated U.S. federal and state income tax returns. Pursuant to rules promulgated by the Internal Revenue Service and various state taxing authorities, the Company will file its initial U.S. income tax returns for the period March 19, 2019 through June 30, 2019. The income tax accounts reflected in the Consolidated Balance Sheet as of June 30, 2019 include income taxes payable and deferred taxes attributed to the Company at the time of and subsequent to the Separation (See Note 12—Related Party Transactions and Twenty-First Century Fox, Inc. Investment under the heading “Corporate Allocations and Twenty-First Century Fox, Inc. Investment”). The calculation of the Company’s income taxes involves considerable judgment and the use of both estimates and allocations. Pursuant to the 21CF Disney Merger Agreement, immediately prior to the Distribution, the Company paid to 21CF a dividend in the amount of $8.5 billion (the “Dividend”). The final determination of the taxes in respect of the Separation and the Distribution for which the Company is responsible pursuant to the 21CF Disney Merger Agreement and a prepayment of the estimated taxes in respect of divestitures (collectively, the “Transaction Tax”) was $6.5 billion. Following the Distribution, on March 20, 2019 the Company received a cash payment in the amount of $2.0 billion (the “Cash Payment”) from Disney, which had the net effect of reducing the Dividend the Company paid to 21CF. The Transaction Tax included a prepayment of the Company’s share of the estimated tax liabilities resulting from the anticipated divestitures by Disney of certain assets, principally the FOX Sports Regional Sports Networks. This prepayment was in the amount of approximately $700 million and is subject to adjustment in the future, when the actual amounts of the tax liabilities are reported on the federal income tax returns of Disney or a subsidiary of Disney. As a result of the Separation and the Distribution, which was a taxable transaction for which the estimated tax liability of $5.8 billion was included in the Transaction Tax paid by the Company, FOX obtained a tax basis in its assets equal to their respective fair market values. This will result in estimated annual tax deductions of approximately $1.5 billion, principally over the next 15 years related to the amortization of the additional tax basis. This amortization is estimated to reduce the Company’s annual cash tax liability by $370 million per year at the current combined federal and state applicable tax rate of 25%. Such estimates are subject to revisions, which could be material, based upon the occurrence of future events including, among other things, a refund of the prepayment discussed above. The consolidated and combined financial statements are referred to as the “Financial Statements” herein. The consolidated and combined statements of operations are referred to as the “Statements of Operations” herein. The consolidated and combined statements of comprehensive income are referred to as the “Statements of Comprehensive Income” herein.

Basis of Presentation

Prior to the Distribution, the Company’s combined financial statements were prepared on a standalone basis, derived from the consolidated financial statements and accounting records of 21CF. The Company’s financial statements as of June 30, 2018 and for the years ended June 30, 2018 and 2017 are presented on a combined basis as the Company was not a separate consolidated group prior to the Distribution. These financial statements reflect the combined historical results of operations, financial position and cash flows of 21CF’s domestic news, national sports and broadcast businesses and certain other assets and liabilities associated with such businesses. The Company became a separate consolidated group as a result of the Distribution, and the Company’s financial statements as of June 30, 2019 and for the year ended June 30, 2019 are presented on a consolidated basis.

The Consolidated and Combined Statements of Operations include allocations for certain support functions that were provided on a centralized basis within 21CF prior to the Distribution and not recorded at the business unit level, such as certain expenses related to finance, legal, insurance, information technology, compliance and human resources management activities, among others. 21CF did not routinely allocate these costs to any of its business units. These expenses have been allocated to FOX on the basis of direct usage when identifiable, with the remainder allocated on a pro rata basis of combined revenues, headcount or other relevant measures. Management believes the assumptions underlying the Consolidated and Combined Financial Statements, including the assumptions regarding allocating general corporate expenses from 21CF, are reasonable. Nevertheless, the Consolidated and Combined Financial Statements may not include all of the actual expenses that would have been incurred by FOX and may not reflect FOX’s consolidated results of operations, financial position and cash flows had it been a standalone company during the entirety of the periods presented. Actual costs that would have been incurred if FOX had been a standalone company would depend on multiple factors, including organizational structure and strategic decisions made in various areas, including information technology and infrastructure.

The Company’s Consolidated Balance Sheet as of June 30, 2019 consists of the Company’s consolidated balances subsequent to the Distribution. The Company’s Combined Balance Sheet as of June 30, 2018 consists of the combined balances of 21CF’s domestic news, national sports and broadcast businesses and certain other assets and liabilities associated with such businesses. The assets and liabilities have been reflected on a historical cost basis, as prior to the Distribution all of the assets and liabilities presented were wholly owned by 21CF and were transferred to the combined FOX group at a carry-over basis.

For purposes of the Company’s financial statements for the periods prior to the Distribution, the income tax provision in the Consolidated and Combined Statements of Operations was calculated as if FOX filed a separate tax return and was operating as a standalone business. Therefore, cash tax payments and items of current and deferred taxes may not be reflective of FOX’s actual tax balances prior to or subsequent to the Distribution. Prior to the Distribution, the Company’s operating results were included in 21CF’s consolidated U.S. federal and state income tax returns. Pursuant to rules promulgated by the Internal Revenue Service and various state taxing authorities, the Company will file its initial U.S. income tax returns for the period March 19, 2019 through June 30, 2019.

The income tax accounts reflected in the Consolidated Balance Sheet as of June 30, 2019 include income taxes payable and deferred taxes attributed to the Company at the time of and subsequent to the Separation (See Note 12—Related Party Transactions and Twenty-First Century Fox, Inc. Investment under the heading “Corporate Allocations and Twenty-First Century Fox, Inc. Investment”). The calculation of the Company’s income taxes involves considerable judgment and the use of both estimates and allocations.

Pursuant to the 21CF Disney Merger Agreement, immediately prior to the Distribution, the Company paid to 21CF a dividend in the amount of $8.5 billion (the “Dividend”). The final determination of the taxes in respect of the Separation and the Distribution for which the Company is responsible pursuant to the 21CF Disney Merger Agreement and a prepayment of the estimated taxes in respect of divestitures (collectively, the “Transaction Tax”) was $6.5 billion.

This prepayment was in the amount of approximately $700 million and is subject to adjustment in the future, when the actual amounts of the tax liabilities are reported on the federal income tax returns of Disney or a subsidiary of Disney.

As a result of the Separation and the Distribution, which was a taxable transaction for which the estimated tax liability of $5.8 billion was included in the Transaction Tax paid by the Company, FOX obtained a tax basis in its assets equal to their respective fair market values. This will result in estimated annual tax deductions of approximately $1.5 billion, principally over the next 15 years related to the amortization of the additional tax basis.
