Senior Secured Credit Facilities

We and certain of our subsidiaries are party to a credit agreement dated as of October 18, 2013, as amended, by and among SGI, as the borrower, SGC, as a guarantor, Bank of America, N.A., as administrative agent, and the lenders and other agents party thereto. This credit facility includes the term loans due in 2020 and 2021, each as set forth in the above table, and a $592.6 million revolving credit facility. Up to $350.0 million of the revolving credit facility is available for issuances of letters of credit.

All of the debt incurred under this credit agreement is subject to accelerated maturity depending on our liquidity at the times each of the 2018 Notes, 2020 Notes and 2021 Notes become due.

2020 Notes and 2021 Notes

During the second quarter of 2016, we repurchased and cancelled $56.5 million and $9.4 million of principal amount of the 2020 Notes and 2021 Notes, respectively, for $34.2 million and $5.7 million in cash, respectively, through separate open market purchases. In connection with this transaction, we recorded a $25.2 million gain on early extinguishment of debt, net of a $0.8 million charge related to the write-off of unamortized debt discount and deferred financing costs associated with the extinguished debt.

Social Gaming Unrestricted Subsidiary Designation

In order to provide flexibility for potential future growth opportunities with respect to our social gaming business, during the third quarter of 2016 we designated certain of our wholly owned direct and indirect subsidiaries, which hold substantially all of the assets of, and operate, our social gaming business, as “Unrestricted Subsidiaries” under our credit agreement and each of the indentures governing the 2018 Notes, 2020 Notes, 2021 Notes, Secured Notes and Unsecured Notes. As a result of such designations, these social gaming subsidiaries are not guarantors under our credit agreement and indentures and are not obligated to comply with many of the covenants set forth in those agreements and that remain applicable to us and our restricted subsidiaries. In addition, except to the extent of cash distributions from these social gaming subsidiaries to us or our restricted subsidiaries, the assets, liabilities and financial results of these social gaming subsidiaries will be excluded from the calculation of the applicable financial metrics required by these agreements, including our credit agreement’s maintenance covenant, which is based on our consolidated net first lien leverage. Following these designations, the social gaming subsidiaries remain wholly owned direct and indirect subsidiaries of the Company.

For additional information regarding our senior secured credit facilities, 2018 Notes, 2020 Notes, 2021 Notes, Secured Notes, Unsecured Notes and capital lease obligations, see Note 15 in our 2015 10-K.

Fair Value of Debt

The estimated fair value of our long-term debt as of September 30, 2016 and December 31, 2015 was approximately $7,976.0 million and $6,931.6 million, respectively. We estimate the fair value of debt based on quoted market prices of our securities, if available, and indicative pricing derived from market information. We categorize inputs used to measure the fair value of debt as Level 2 in the fair value hierarchy due to the low volume and frequency of transactions in the market.
