The following is a summary description of our principal indebtedness as of December 31, 2015:

2015 Senior Notes

On September 15, 2015, we issued senior unsecured notes for an aggregate principal amount of $6.0 billion, consisting of the following:


•	$1.5 billion of 2.90% Senior Notes due September 15, 2020, valued at 99.792% of par;


•	$1.0 billion of 3.625% Senior Notes due September 15, 2022, valued at 99.920% of par;


•	$1.75 billion of 4.05% Senior Notes due September 15, 2025, valued at 99.764% of par; and


•	$1.75 billion of 5.20% Senior Notes due September 15, 2045, valued at 99.294% of par.

These notes are senior unsecured obligations and may be redeemed at our option at any time at 100% of the principal amount plus accrued interest and a specified make-whole amount. The notes also contain a change of control provision that may require us to purchase the notes at a price equal to 101% of the principal amount plus accrued and unpaid interest to the date of purchase under certain circumstances.

The costs associated with this offering of approximately $47.5 million have been recorded as a reduction to the carrying amount of the debt on our consolidated balance sheet. These costs along with the discounts will be amortized as additional interest expense using the effective interest rate method over the period from issuance through maturity. Interest on the notes is payable March 15 and September 15 of each year.

In connection with this offering, we also entered into interest rate swaps. The carrying value of the 2.90% Senior Notes includes approximately $1.8 million related to changes in the fair value of the interest rate swaps. For additional information, please read Note 9, Derivative Instruments, to these consolidated financial statements.

2008 Senior Notes

On March 4, 2008, we issued $550.0 million aggregate principal amount of 6.875% Senior Notes due March 1, 2018 that were originally priced at 99.184% of par. The discount is amortized as additional interest expense over the period from issuance through maturity. These notes are senior unsecured obligations. Interest on the notes is payable March 1 and September 1 of each year. The notes may be redeemed at our option at any time at 100% of the principal amount plus accrued interest and a specified make-whole amount. The notes contain a change of control provision that may require us to purchase the notes under certain circumstances. There is also an interest rate adjustment feature that requires us to pay interest at an increased rate on the notes if the credit rating on the notes declines below investment grade. In accordance with ASU No. 2015-03, during 2015, we reclassified $1.8 million of our debt issuance costs related to our 6.875% Senior Notes from an asset to a reduction to the carrying amount of the 6.875% Senior Notes in our 2014 consolidated balance sheet.

Upon the issuance of the 6.875% Senior Notes due in 2018, we entered into interest rate swap contracts where we received a fixed rate and paid a variable rate. These contracts were terminated in December 2008. Upon termination of these swaps, the carrying amount of the 6.875% Senior Notes due in 2018 was increased by $62.8 million and is being amortized using the effective interest rate method over the remaining life of the Senior Notes and is being recognized as a reduction of interest expense. As of December 31, 2015, $17.8 million remains to be amortized.

Notes Payable to Fumedica

In connection with our 2006 distribution agreement with Fumedica, we issued notes totaling 61.4 million Swiss Francs which were payable to Fumedica in varying amounts from June 2008 through June 2018. Our remaining note payable to Fumedica had a carrying value of 8.9 million Swiss Francs ($9.0 million) and 11.6 million Swiss Francs ($11.7 million) as of December 31, 2015 and 2014, respectively.

Credit Facility

In August 2015, we entered into a $1.0 billion, 5-year senior unsecured revolving credit facility under which we are permitted to draw funds for working capital and general corporate purposes. The terms of the revolving credit facility include a financial covenant that requires us not to exceed a maximum consolidated leverage ratio. As of December 31, 2015, we had no outstanding borrowings and were in compliance with all covenants under this facility.

In March 2013, we entered into a $750.0 million 364-day senior unsecured revolving credit facility. In March 2014, the revolving credit facility expired and was not renewed.

Financing Arrangement

During 2015 we recorded a financing obligation in relation to the amendment of our lease agreement of Eisai's oral solid dose products manufacturing facility in RTP, North Carolina where we manufacture our and Eisai's oral solid dose products. As of December 31, 2015, the financing obligation totaled approximately $19.8 million. For additional information, please read Note 10, Property, Plant and Equipment to these consolidated financial statements.
