[1] In December 2012, Sirius XM entered into a five-year Credit Facility with a syndicate of financial institutions for $1,250,000. Sirius XM's obligations under the Credit Facility are guaranteed by certain of its material domestic subsidiaries and are secured by a lien on substantially all of Sirius XM's assets and the assets of its material domestic subsidiaries. Borrowings under the Credit Facility are used for working capital and other general corporate purposes, including dividends, financing of acquisitions and share repurchases. Interest on borrowings is payable on a quarterly basis and accrues at a rate based on LIBOR plus an applicable rate. Sirius XM is also required to pay a variable fee on the average daily unused portion of the Credit Facility and is payable on a quarterly basis. The variable rate for the Credit Facility was 0.35% per annum as of March 31, 2014. As of March 31, 2014, $940,000 was available for future borrowing under the Credit Facility. Sirius XM's outstanding borrowings under the Credit Facility are classified as Long-term debt within our unaudited consolidated balance sheets as of March 31, 2014 due to the long-term maturity of this debt.
