On June 29, 2018, Sirius XM Radio Inc. (“Sirius XM”), our subsidiary, entered into an amendment (“Amendment No. 3”) to its existing $1.75 billion senior secured revolving credit facility with JPMorgan Chase Bank, N.A, as the administrative agent, and other agents and lenders, to, among other things, extend the maturity of the existing facility to June 29, 2023 (as amended, the “Credit Agreement”).

Amendment No. 3 provides for certain changes to Sirius XM’s $1.75 billion senior secured revolving credit facility, under which Sirius XM may borrow and reborrow from time to time. Sirius XM may use borrowings under the Credit Agreement for working capital and other general corporate purposes, including share repurchases, dividends and the financing of acquisitions. The obligations under the Credit Agreement are guaranteed by Sirius XM’s material domestic subsidiaries. The obligations under the Credit Agreement are secured by a lien on substantially all of our assets and the assets of Sirius XM’s material domestic subsidiaries, subject to certain exceptions.

The Credit Agreement contains incremental facilities and related debt and lien baskets, which allow Sirius XM to increase or incur new commitments under the revolving facility and/or incur new term loans or other forms of indebtedness, subject to the terms of the Credit Agreement.

Amendment No. 3, among other things, modifies the pricing grid to reduce interest rates and commitment fees upon attaining certain leverage levels, increases from $1 billion to $2 billion the uncommitted incremental facilities under the Credit Agreement and related debt and lien basket capacity correspondingly, increases the thresholds from $150 million to $300 million for the cross-default and judgment default events of default, and adds the ability to borrow in Canadian Dollars up to a C$250 million sublimit (with Canadian borrowings reducing available commitments under the Credit Agreement).

Certain of the participants in the Credit Agreement and their respective affiliates have engaged in, and may in the future engage in, investment banking, advisory roles and other commercial dealings in the ordinary course of business with us and/or our affiliates. These participants have received, or may in the future receive, customary fees and commissions for these transactions.

The description of Amendment No. 3 contained herein is qualified in its entirety by reference to Amendment No. 3, a copy of which is filed herewith as Exhibit 10.1 and incorporated herein by reference.

The response to Item 1.01 is hereby incorporated into this Item 2.03.
