Exchange Agreement with Chairman
On June 13, 2022, Liberty Broadband entered into an Exchange Agreement with its Chairman of the board of directors, John C. Malone, and a revocable trust of which Mr. Malone is the sole trustee and beneficiary (the “JM Trust”) (the “Exchange Agreement”).

Spin-Off Arrangements
During May 2014, the board of directors of Liberty Media Corporation and its subsidiaries (“Liberty”) authorized management to pursue a plan to spin-off to its stockholders common stock of a wholly owned subsidiary, Liberty Broadband, and to distribute subscription rights to acquire shares of Liberty Broadband’s common stock (the “Broadband Spin-Off”). In connection with the Broadband Spin-Off, Liberty (for accounting purposes a related party of the Company) and Liberty Broadband entered into certain agreements in order to govern certain of the ongoing relationships between the two companies and to provide for an orderly transition, including a services agreement and a facilities sharing agreement. Under the facilities sharing agreement, Liberty Broadband shares office space with Liberty and related amenities at Liberty’s corporate headquarters. Liberty Broadband reimburses Liberty for direct, out-of-pocket expenses incurred by Liberty in providing these services which are negotiated semi-annually.
Pursuant to the services agreement, Liberty provides Liberty Broadband with general and administrative services including legal, tax, accounting, treasury and investor relations support. In December 2019, the Company entered into an amendment to the services agreement with Liberty in connection with Liberty’s entry into a new employment arrangement with Gregory B. Maffei, the Company’s President and Chief Executive Officer. Under the amended services agreement, components of his compensation would either be paid directly to him by each of the Company, Liberty TripAdvisor Holdings, Inc. and Qurate Retail, Inc. (“Qurate Retail”) (collectively, the “Service Companies”) or reimbursed to Liberty, in each case, based on allocations among Liberty and the Service Companies set forth in the amended services agreement, currently set at 23% for the Company but subject to adjustment on an annual basis upon the occurrence of certain events.
Additionally, in connection with a prior transaction, GCI Liberty and Qurate Retail (for accounting purposes a related party of the Company) entered into a tax sharing agreement, which was assumed by Liberty Broadband as a result of the Combination. The tax sharing agreement provides for the allocation and indemnification of tax liabilities and benefits between Qurate Retail and Liberty Broadband and other agreements related to tax matters.
Under these various agreements, amounts reimbursable to Liberty were approximately $1 million and $2 million for the three months ended June 30, 2023 and 2022, respectively, and $3 million and $5 million for the six months ended June 30, 2023 and 2022, respectively. Liberty Broadband had a tax sharing receivable with Qurate Retail of $14 million and $7
