The Senior Notes are senior unsecured obligations of Celanese US and rank equally in right of payment with all other unsubordinated indebtedness of Celanese US. The Senior Notes were issued under indentures (collectively, the "Indentures") among Celanese US, Celanese and each of the domestic subsidiaries of Celanese US that guarantee its obligations under its senior secured credit facilities ("Subsidiary Guarantors") and Wells Fargo Bank, National Association, as trustee. The Senior Notes are guaranteed on a senior unsecured basis by Celanese and the Subsidiary Guarantors. The Indentures contain covenants, including, but not limited to, restrictions on the Company's ability to incur indebtedness; grant liens on assets; merge, consolidate, or sell assets; pay dividends or make other restricted payments; engage in transactions with affiliates; or engage in other businesses. Celanese US may redeem some or all of each of the Senior Notes, prior to their respective maturity dates, at a redemption price of 100% of the principal amount, plus a "make-whole" premium as specified in the applicable indenture, plus accrued and unpaid interest, if any, to the redemption date.

In October 2014, Celanese US redeemed its $600 million of principal amount of 6.625% unsecured senior notes due 2018 ("6.625% Notes") at a redemption price of 103.313% of the face amount for a total principal and premium payment of $620 million plus accrued interest of $20 million. Proceeds from the issuance of the 3.250% Notes were used to partially fund the redemption of the 6.625% Notes, as well as cash on hand. The Company recognized a loss on the extinguishment of the 6.625% Notes comprised of the redemption premium of $20 million and accelerated amortization of deferred financing costs of $4 million, which were included in Refinancing expense in the consolidated statement of operations for the year ended December 31, 2014.

Senior Credit Facilities

In September 2014, Celanese US, Celanese and the Subsidiary Guarantors entered into an amendment agreement with the lenders under Celanese US's existing senior secured credit facilities in order to amend and restate the amended credit agreement dated September 16, 2013 (as amended and restated by the 2014 amendment agreement, the "Amended Credit Agreement"). Under the Amended Credit Agreement, all of the US dollar denominated Term C-2 term loans and all but €28 million of the Euro-denominated Term C-2 term loans under the 2013 amended credit agreement were converted into, or refinanced by, the Term C-3 loan facility with an extended maturity date of October 2018. The non-extended portions of the Term C-2 loan facility continue to have a maturity date of October 2016. In addition, the maturity date of the Company's revolving credit facility was extended to October 2018 and the facility was increased to $900 million. Accordingly, the Amended Credit Agreement consists of the Term C-2 loan facility, the Term C-3 loan facility and a $900 million revolving credit facility.

Net deferred financing costs are as follows:

⁽¹⁾	Relates to the September 2013 amendment to the Celanese US existing senior secured credit facilities to reduce the interest rates payable in connection with certain borrowings thereby creating the Term C-2 loan facility due 2016.


⁽²⁾	Includes $6 million related to the issuance of the 3.250% Notes and $4 million related to the September 2014 amendment to the Celanese US existing senior secured credit facilities.


⁽³⁾	Includes $4 million related to the 6.625% Notes redemption and $1 million related to the Term C-2 loan facility conversion.


⁽⁴⁾	Includes $4 million and $5 million as of December 31, 2015 and 2014, respectively, related to the Company's revolving credit facility and accounts receivables securitization facility, which are included in Other noncurrent assets in the consolidated balance sheets.

As of December 31, 2015, the margin for borrowings under the Term C-2 loan facility was 2.0% above the Euro Interbank Offered Rate ("EURIBOR") and the margin for borrowings under the Term C-3 loan facility was 2.25% above LIBOR (for US dollars) and 2.25% above EURIBOR (for Euros), as applicable. As of December 31, 2015, the margin for borrowings under the revolving credit facility was 1.5% above LIBOR. The margin for borrowings under the revolving credit facility is subject to increase or decrease in certain circumstances based on changes in the corporate credit ratings of Celanese or Celanese US.

Term loan borrowings under the Amended Credit Agreement are subject to amortization at 1% of the initial principal amount per annum, payable quarterly. In addition, the Company pays quarterly commitment fees on the unused portion of the revolving credit facility of 0.25% per annum.

The Amended Credit Agreement is guaranteed by Celanese and certain domestic subsidiaries of Celanese US and is secured by a lien on substantially all assets of Celanese US and such guarantors, subject to certain agreed exceptions (including for certain real property and certain shares of foreign subsidiaries), pursuant to the Guarantee and Collateral Agreement, dated April 2, 2007.

As a condition to borrowing funds or requesting letters of credit be issued under the revolving credit facility, the Company's first lien senior secured leverage ratio (as calculated as of the last day of the most recent fiscal quarter for which financial statements have been delivered under the revolving facility) cannot exceed the threshold as specified below. Further, the Company's first lien senior secured leverage ratio must be maintained at or below that threshold while any amounts are outstanding under the revolving credit facility.

The Company's amended first lien senior secured leverage ratios under the revolving credit facility are as follows:



As of December 31, 2015
Maximum	Estimate	Estimate, if Fully Drawn
3.90	0.92	1.30

The Amended Credit Agreement contains covenants including, but not limited to, restrictions on the Company's ability to incur indebtedness; grant liens on assets; merge, consolidate, or sell assets; pay dividends or make other restricted payments; make investments; prepay or modify certain indebtedness; engage in transactions with affiliates; enter into sale-leaseback transactions or hedge transactions; or engage in other businesses; as well as a covenant requiring maintenance of a maximum first lien senior secured leverage ratio.

The Amended Credit Agreement also maintains a number of events of default, including a cross default to other debt of Celanese, Celanese US, or their subsidiaries, including the Senior Notes, in an aggregate amount equal to more than $50 million and the occurrence of a change of control. Failure to comply with these covenants, or the occurrence of any other event of default, could result in acceleration of the borrowings and other financial obligations under the Amended Credit Agreement.

The Company is in compliance with all of the covenants related to its debt agreements as of December 31, 2015.

Accounts Receivables Securitization Facility

In August 2013, the Company entered into a US accounts receivable securitization facility pursuant to (i) a Purchase and Sale Agreement ("Sale Agreement") among certain US subsidiaries of the Company (each an "Originator"), Celanese International Corporation ("CIC") and CE Receivables LLC, a wholly-owned, "bankruptcy remote" special purpose subsidiary of an Originator ("Transferor") and (ii) a Receivables Purchase Agreement ("Purchase Agreement"), among CIC, as servicer, the Transferor, various third-party purchasers (collectively, "Purchasers") and The Bank of Tokyo-Mitsubishi UFJ, Ltd., New York Branch, as administrator ("Administrator"). During 2015, the Sale Agreement and the Purchase Agreement were amended to reflect changes to the parties. The Purchase Agreement expires in 2016, but may be extended for successive one year terms by agreement of the parties. All of the Transferor's assets have been pledged to the Administrator in support of its obligations under the Purchase Agreement.
