Item 7.01. Regulation FD Disclosure

As announced by Liberty Media Corporation (the Company) on May 8, 2014, the Company’s board of directors previously approved a dividend (the Dividend) of two shares of the Company’s Series C common stock, par value $.01 per share, for each outstanding share of its Series A common stock, par value $.01 per share, and each outstanding share of its Series B common stock, par value $.01 per share, held as of 5:00 p.m. New York City time on July 7, 2014, the record date for Dividend.  The Company previously announced a payment date for the Dividend of July 10, 2014; however, the payment date for the Dividend has been changed to 5:00 p.m. New York City time on July 23, 2014 (the payment date) to allow for a longer when-issued trading period in the Series C common stock.

In connection with the issuance of shares of Series C common stock in the Dividend, an adjustment is required to be made to the conversion rate (the Conversion Rate) for the Company’s 1.375% Cash Convertible Senior Notes due 2023 (the Notes) pursuant to the terms of the Indenture, dated October 17, 2013, between the Company and U.S. Bank National Association, as trustee, governing the Notes (the Indenture). On June 17, 2014, the Company provided notice to the holders of the Notes informing them of the pending adjustment to the Conversion Rate, a copy of which is furnished herewith as Exhibit 99.1.  The Company will provide a second notice to the holders of the Notes once the actual adjustment is made.

In calculating the appropriate adjustment to the Conversion Rate, the Company intends to apply the formula set forth in Section 12.04(c) of the Indenture for Distributed Property (as such term is defined in the Indenture) and to take into account the trading prices of the Series A common stock and the when-issued trading prices of the Series C common stock during the last ten trading days prior to and including the payment date.  However, the Company retains the right to not use the when-issued trading prices for the Series C common stock in making the applicable adjustment to the Conversion Rate if, for example, no when-issued trading market develops or the Company determines that the when-issued trading prices are not reflective of the fair value of the Series C common stock.  The Company will announce the actual adjustment to the Conversion Rate promptly following the payment date, and in any event prior to the opening of trading on July 24, 2014, the ex-dividend date.
