1.375% Cash Convertible Notes due 2023

On October 17, 2013, Liberty issued $1 billion aggregate principal amount of 1.375% Cash Convertible Senior Notes due 2023 ("Convertible Notes").  The Convertible Notes will mature on October 15, 2023 unless earlier repurchased by us or converted.  Interest on the Convertible Notes is payable semi-annually in arrears on April 15 and October 15 of each year at a rate of 1.375% per annum. All conversions of the Convertible Notes will be settled solely in cash, and not through the delivery of any securities.

The Convertible Notes are convertible into cash based on the product of the conversion rate specified in the related indenture and the Securities Basket. A supplemental indenture entered into on April 15, 2016 amends the conversion, adjustment and other provisions of the indenture and provides that the conversion consideration due upon conversion of any Convertible Note shall be determined as if references in the indenture to one share of Series A Liberty Media Corporation common stock were instead a reference to the Securities Basket, initially consisting of 0.10 of a share of Series A Liberty Braves common stock, 1.0 share of Series A Liberty SiriusXM common stock and 0.25 of a share of Series A Liberty Formula One common stock. The Series A Liberty Braves common stock component of the Securities Basket was adjusted to 0.1087 pursuant to anti-dilution adjustments arising out of the distribution of subscription rights to purchase shares of Series C Liberty Braves common stock made to all holders of Liberty Braves common stock.

Holders of the Convertible Notes may convert their notes at their option at any time prior to the close of business on the second business day immediately preceding the maturity date of the notes under certain circumstances. Liberty has elected to account for this instrument using the fair value option.  Accordingly, changes in the fair value of this instrument are recognized as unrealized gains (losses) in the condensed consolidated statements of operations.  As of March 31, 2019, the Convertible Notes are classified as a long term liability in the condensed consolidated balance sheet, as the conversion conditions have not been met as of such date.

Additionally, contemporaneously with the issuance of the Convertible Notes, Liberty entered into privately negotiated cash convertible note hedges and purchased call options (the “Bond Hedge Transaction”). The Bond Hedge Transaction is expected to offset potential cash payments Liberty would be required to make in excess of the principal amount of the Convertible Notes, upon conversion of the notes in the event that the volume-weighted average price per share of the Series A Liberty Media Corporation common stock, as measured under the cash convertible note hedge transactions on each trading day of the relevant cash settlement averaging period or other relevant valuation period, was greater than the strike price of Series A Liberty Media Corporation common stock, which corresponded to the conversion price of the Convertible Notes. On April 15, 2016, Liberty entered into amendments to the Bond Hedge Transaction. As of such date, the Bond Hedge Transaction covered, in the aggregate, 5,271,475 shares of Series A Liberty Formula One common stock, 21,085,900 shares of Series A Liberty SiriusXM common stock and 2,108,590 shares of Series A Liberty Braves common stock, subject to anti-dilution adjustments pertaining to the Convertible Notes, which was equal to the aggregate number of shares comprising the Securities Basket underlying the Convertible Notes at that time. The aggregate number of shares of Series A Liberty Braves common stock relating to the Bond Hedge Transaction was increased to 2,292,037. As of March 31, 2019, the basket price of the securities underlying the Bond Hedge Transaction was $49.73 per share. The expiration of these instruments is October 15, 2023. The fair value of these instruments is included in Other assets as of March 31, 2019 and December 31, 2018 in the accompanying condensed consolidated balance sheets, with changes in the fair value recorded as unrealized gains (losses) on financial instruments in the accompanying condensed consolidated statements of operations.

Concurrently with the Convertible Notes and Bond Hedge Transaction, Liberty also entered into separate privately negotiated warrant transactions under which Liberty sold warrants relating to the same number of shares of common stock as underlie the Bond Hedge Transaction, subject to anti-dilution adjustments (“Warrant Transactions”). The first expiration date of the warrants is January 16, 2024 and the remainder expire over a period covering 81 days thereafter. Liberty may elect to settle its delivery obligation under the Warrant Transactions with cash. Liberty entered into amendments to the Warrant Transactions with each of the option counterparties (“Amended Warrant Transactions”).  As of April 15, 2016, the Amended Warrant Transactions covered, in the aggregate, 5,271,475 shares of Series A Liberty Formula One common stock, 21,085,900 shares of Series A Liberty SiriusXM common stock and 2,108,590 shares of Series A Liberty Braves common stock, subject to anti-dilution adjustments. The aggregate number of shares of Series A Liberty Braves common stock relating to the Amended Warrant Transactions was increased to 2,292,037 pursuant to anti-dilution adjustments arising out of the rights distribution. The strike price of the warrants was adjusted to $61.16 per share. As of March 31, 2019, the basket price of the securities underlying the Amended Warrant Transactions was $49.73 per share. The Amended Warrant Transactions may have a dilutive effect with respect to the shares comprising the Securities Basket underlying the warrants to the extent that the settlement price exceeds the strike price of the warrants, and the warrants are settled in shares comprising such Securities Basket.

The Convertible Notes, Bond Hedge Transaction and Warrant Transactions are attributed to the Formula One Group.

1% Cash Convertible Notes due 2023

In connection with the acquisition of Delta Topco on January 23, 2017, Liberty issued $450 million aggregate principal amount of 1% Cash Convertible Senior Notes due 2023 at an interest rate of 1% per annum, which are convertible, under certain circumstances, into cash based on the trading prices of the underlying shares of Series C Liberty Formula One common stock and mature on January 30, 2023 (the ‘‘1% Cash Convertible Notes due 2023’’). The initial conversion rate for the notes will be 27.1091 shares of Series C Liberty Formula One common stock per $1,000 principal amount of notes, equivalent to an initial conversion price of approximately $36.89 per share of Series C Liberty Formula One common stock. The conversion of the 1% Cash Convertible Notes due 2023 will be settled solely in cash, and not through the delivery of any securities. Liberty used a portion of the net proceeds of the 1% Cash Convertible Notes due 2023 to increase the cash consideration payable to the selling shareholders of Formula 1 by approximately $400 million.

2.25% Exchangeable Senior Debentures due 2046

On August 17, 2016, Liberty closed a private offering of approximately $445 million aggregate principal amount of its 2.25% exchangeable senior debentures due 2046 (the “2.25% Exchangeable Senior Debentures due 2046”), and shares of the Company’s Time Warner common stock were the reference shares attributable to the debentures. On June 14, 2018, AT&T Inc. (“AT&T”) acquired Time Warner in a stock-and-cash transaction. In accordance with the terms of the indenture governing the 2.25% Exchangeable Senior Debentures due 2046, the cash portion of the acquisition consideration was paid on June 22, 2018 as an extraordinary additional distribution to holders of debentures, and the stock portion of the acquisition consideration became reference shares attributable to the debentures. Also pursuant to the indenture, the original principal amount of the 2.25% Exchangeable Senior Debentures due 2046 was reduced by an amount equal to the extraordinary additional distribution of $229 million, calculated as $514.1295 per $1,000 original principal amount of debentures. Additionally, any amount of excess regular quarterly cash dividends paid on the AT&T reference shares will be distributed by the Company to holders of the debentures as an additional distribution.

Upon an exchange of debentures, Liberty, at its option, may deliver AT&T common stock, cash or a combination of AT&T common stock and cash. The number of shares of AT&T common stock attributable to a debenture represents an initial exchange price of approximately $35.35 per share. A total of approximately 6.11 million shares of AT&T common stock are attributable to the debentures. Interest is payable quarterly on March 31, June 30, September 30 and December 31 of each year, commencing December 31, 2016. The debentures may be redeemed by Liberty, in whole or in part, on or after October 5, 2021. Holders of the debentures also have the right to require Liberty to purchase their debentures on October 5, 2021. The redemption and purchase price will generally equal 100% of the adjusted principal amount of the debentures plus accrued and unpaid interest.

The debentures, as well as the associated cash proceeds, were attributed to the Formula One Group. Liberty has elected to account for the debentures using the fair value option. Accordingly, changes in the fair value of these instruments are recognized as unrealized gains (losses) in the condensed consolidated statements of operations.

Pandora 1.75% Convertible Senior Notes due 2023

The value assigned to the debt components of the 1.75% Convertible Senior Notes due 2023 is the estimated fair value as of the issuance date of similar debt without the conversion feature. The difference between the fair value of the debt and this estimated fair value represents the value which has been assigned to the equity component. The equity component is recorded to noncontrolling interest in equity of subsidiaries and is not remeasured as long as it continues to meet the conditions for equity classification. The excess of the principal amount of the 1.75% Convertible Senior Notes due 2023 over the carrying amount of the liability component is recorded as a debt discount, and is being amortized to interest expense using the effective interest method through the December 1, 2023 maturity date. 

SIRIUS XM Holdings Senior Secured Revolving Credit Facility

SIRIUS XM Holdings entered into a Senior Secured Revolving Credit Facility (the "Credit Facility") with a syndicate of financial institutions with a total borrowing capacity of $1,750 million which matures in June 2023.
