Debt instrument description										The 2020 Notes are guaranteed on an unsecured senior basis by each of the Guarantor Subsidiaries. The 2020 Notes and the guarantees are the Company's and the Guarantor Subsidiaries' general senior unsecured obligations and rank equally in right of payment with all of the Company's existing and future unsecured unsubordinated debt. The 2020 Notes and the guarantees are effectively junior in right of payment to their existing and future secured debt, including under the Credit Facility (to the extent of the value of the assets securing such debt), are structurally subordinated to all existing and future liabilities (including trade payables) of the Company's subsidiaries that are not guarantors of the 2020 Notes, and are senior in right of payment to all of their existing and future subordinated indebtedness. The indenture governing the 2020 Notes limits, among other things, the Company's and its restricted subsidiaries' ability to: incur, assume or guarantee additional debt; issue redeemable stock and preferred stock; pay dividends, make distributions or redeem or repurchase capital stock; prepay, redeem or repurchase subordinated debt; make loans and investments; grant or incur liens; restrict dividends, loans or asset transfers from restricted subsidiaries; sell or otherwise dispose of assets; enter into transactions with affiliates; reduce the Company's satellite insurance; and consolidate or merge with, or sell substantially all of their assets to, another person. Prior to June 15, 2015, the Company may redeem up to 35% of the 2020 Notes at a redemption price of 106.875% of the principal amount thereof, plus accrued and unpaid interest, if any, thereon to the redemption date, from the net cash proceeds of specified equity offerings. The Company may also redeem the 2020 Notes prior to June 15, 2016, in whole or in part, at a redemption price equal to 100% of the principal amount thereof plus the applicable premium and any accrued and unpaid interest, if any, thereon to the redemption date. The applicable premium is calculated as the greater of: (i) 1.0% of the principal amount of such 2020 Notes and (ii) the excess, if any, of (a) the present value at such date of redemption of (1) the redemption price of such 2020 Notes on June 15, 2016 plus (2) all required interest payments due on such 2020 Notes through June 15, 2016 (excluding accrued but unpaid interest to the date of redemption), computed using a discount rate equal to the treasury rate (as defined under the indenture) plus 50 basis points, over (b) the then-outstanding principal amount of such 2020 Notes. The 2020 Notes may be redeemed, in whole or in part, at any time during the twelve months beginning on June 15, 2016 at a redemption price of 103.438%, during the twelve months beginning on June 15, 2017 at a redemption price of 101.719%, and at any time on or after June 15, 2018 at a redemption price of 100%, in each case plus accrued and unpaid interest, if any, thereon to the redemption date. In the event a change of control occurs (as defined in the indenture), each holder will have the right to require the Company to repurchase all or any part of such holder's 2020 Notes at a purchase price in cash equal to 101% of the aggregate principal amount of the 2020 Notes repurchased plus accrued and unpaid interest, if any, to the date of purchase (subject to the right of holders of record on the relevant record date to receive interest due on the relevant interest payment date).			On November 14, 2012, the Company redeemed the remaining $12.9 million in aggregate principal amount of 2016 Notes pursuant to the optional redemption provisions of the 2016 Notes at a redemption price of 106.656% of the principal amount, plus accrued and unpaid interest to, but not including, the redemption date.	On October 12, 2012, the Company purchased approximately $262.1 million in aggregate principal amount of the 2016 Notes pursuant to the tender offer. The total cash payment to purchase the tendered 2016 Notes in the tender offer, including accrued and unpaid interest up to, but excluding, the repurchase date and a $10 consent payment per $1,000 principal amount of notes tendered, was approximately $282.5 million.
