Revolving Credit Facility

On April 10, 2015, we entered into a new $2.000 billion revolving credit facility (the 2015 Facility) with a global syndicate of commercial banks and terminated our previous $2.000 billion revolving credit facility. The 2015 Facility matures on April 10, 2020. Eurodollar and multicurrency loans under the 2015 Facility bear interest at LIBOR plus an interest margin of between 0.900 percent and 1.500 percent, based on our corporate credit ratings and consolidated leverage ratio (1.300 percent, as of December 31, 2015). In addition, we are required to pay a facility fee based on our credit ratings, consolidated leverage ratio, and the total amount of revolving credit commitments, regardless of usage, under the agreement (0.200 percent, as of December 31, 2015). The 2015 Facility contains covenants which, among other things, require that we maintain a minimum interest coverage ratio of 3.0 times consolidated EBITDA and a maximum leverage ratio of 4.5 times consolidated EBITDA for the first four fiscal quarter-ends following the closing of the AMS Portfolio Acquisition on August 3, 2015, and decreasing to 4.25 times, 4.00 times, and 3.75 times consolidated EBITDA for the next three fiscal quarter-ends after such four fiscal quarter-ends, respectively, and then to 3.50 times for each fiscal quarter-end thereafter. There were no amounts borrowed under our current and prior revolving credit facilities as of December 31, 2015 or December 31, 2014.

Our revolving credit facility agreement in place as of December 31, 2015 requires that we maintain certain financial covenants, as follows:



	Covenant Requirement	Actual as of December 31, 2015
Maximum leverage ratio (1)	4.5 times	3.0 times
Minimum interest coverage ratio (2)	3.0 times	6.6 times


(1)	Ratio of total debt to consolidated EBITDA, as defined by the credit agreement, for the preceding four consecutive fiscal quarters.


(2)	Ratio of consolidated EBITDA, as defined by the credit agreement, to interest expense for the preceding four consecutive fiscal quarters.

The credit agreement for the 2015 Facility provides for an exclusion from the calculation of consolidated EBITDA, as defined by the agreement, through the credit agreement maturity, of any non-cash charges and up to $620 million in restructuring charges and restructuring-related expenses related to our current or future restructuring plans. As of December 31, 2015, we had $558 million of the restructuring charge exclusion remaining. In addition, any cash litigation payments (net of any cash litigation receipts), as defined by the agreement, are excluded from the calculation of consolidated EBITDA and any new debt issued to fund any tax deficiency payments is excluded from consolidated total debt, as defined in the agreement, provided that the sum of any excluded net cash litigation payments and any new debt issued to fund any tax deficiency payments not exceed $2.000 billion in the aggregate. As of December 31, 2015, we had approximately $1.803 billion of the combined legal and debt exclusion remaining. On October 23, 2015, the definition of consolidated EBITA was amended to exclude $300 million of litigation payments paid after the closing date of the 2015 Facility, pursuant to the February 13, 2015 settlement agreement with Johnson & Johnson and the other parties thereto.

As of and through December 31, 2015, we were in compliance with the required covenants.

Any inability to maintain compliance with these covenants could require us to seek to renegotiate the terms of our credit facility or seek waivers from compliance with these covenants, both of which could result in additional borrowing costs. Further, there can be no assurance that our lenders would agree to such new terms or grant such waivers.

Term Loans

As of December 31, 2015, we had an aggregate $1.000 billion outstanding under our unsecured term loan facilities and $400 million outstanding under these facilites as of December 31, 2014. These facilities include an unsecured term loan facility entered into in August 2013 (2013 Term Loan) which had $250 million outstanding as of December 31, 2015 and $400 million outstanding as of December 31, 2014, along with an unsecured term loan credit facility entered into in April 2015 (2015 Term Loan) which had $750 million outstanding as of December 31, 2015.

Borrowings under the 2013 Term Loan bear interest at LIBOR plus an interest margin of between 1.0 percent and 1.75 percent (currently 1.5 percent), based on our corporate credit ratings and consolidated leverage ratio. We repaid $150 million of our 2013 Term Loan facility during 2015. As a result and in accordance with the credit agreement, the remaining amount outstanding is payable with $10 million due in the fourth quarter of 2017, $20 million due in both the first and second quarters of 2018 and the remaining principal amount due at the final maturity date in August 2018. The 2013 Term Loan borrowings are repayable at any time without premium or penalty. Our term loan facility requires that we comply with certain covenants, including financial covenants with respect to maximum leverage and minimum interest coverage, consistent with the 2015 Facility. The maximum leverage ratio requirement is 4.5 times, our actual leverage ratio as of December 31, 2015 is 3.0 times, and the minimum interest coverage ratio requirement is 3.0 times, our actual interest coverage ratio as of December 31, 2015 is 6.6 times.

On April 10, 2015, we entered into a new $750 million unsecured term loan credit facility (2015 Term Loan) which matures on August 3, 2020. The 2015 Term Loan was funded on August 3, 2015 and was used to partially fund the AMS Portfolio Acquisition, including the payment of fees and expenses. Term loan borrowings under this facility bear interest at LIBOR plus an interest margin of between 1.00 percent and 1.75 percent (currently 1.50 percent), based on our corporate credit ratings and consolidated leverage ratio. The 2015 Term Loan requires quarterly principal payments of $38 million commencing in the third quarter of 2017, and the remaining principal amount is due at the final maturity date of August 3, 2020. The 2015 Term Loan agreement requires that we comply with certain covenants, including financial covenants with respect to maximum leverage and minimum interest coverage, consistent with the 2015 Facility. The maximum leverage ratio requirement is 4.5 times, our actual leverage ratio as of December 31, 2015 is 3.0 times, and the minimum interest coverage ratio requirement is 3.0 times, our actual interest coverage ratio as of December 31, 2015 is 6.6 times.

Senior Notes

We had senior notes outstanding of $4.650 billion as of December 31, 2015 and $3.800 billion outstanding as of December 31, 2014. In May 2015, we completed the offering of $1.850 billion in aggregate principal amount of senior notes consisting of $600 million in aggregate principal amount of 2.850% notes due 2020, $500 million in aggregate principal amount of 3.375% notes due 2022 and $750 million in aggregate principal amount of 3.850% notes due 2025. The net proceeds from the offering of the notes, after deducting underwriting discounts and estimated offering expenses, were approximately $1.830 billion. We used a portion of the net proceeds from the senior notes offering to redeem $400 million aggregate principal amount of our 5.500% notes due November 2015 and $600 million aggregate principal amount of our 6.400% notes due June 2016. The remaining senior notes offering proceeds, together with the 2015 Term Loan, were used to fund the AMS Portfolio Acquisition. We recorded a charge of $45 million in interest expense for premiums, accelerated amortization of debt issuance costs, and investor discount costs net of interest rate hedge gains related to the early debt extinguishment.

Our senior notes were issued in public offerings, are redeemable prior to maturity and are not subject to any sinking fund requirements. Our senior notes are unsecured, unsubordinated obligations and rank on parity with each other. These notes are effectively junior to borrowings under our credit and security facility, to the extent if directly borrowed by our subsidiaries, and to liabilities of our subsidiaries (see Other Arrangements below).

Our senior notes consist of the following as of December 31, 2015:



	Amount (in millions)		Issuance Date	Maturity Date	Semi-annual Coupon Rate
January 2017 Notes	$	250	November 2004	January 2017	5.125%
October 2018 Notes	600		August 2013	October 2018	2.650%
January 2020 Notes	850		December 2009	January 2020	6.000%
May 2020 Notes	600		May 2015	May 2020	2.850%
May 2022 Notes	500		May 2015	May 2022	3.375%
May 2025 Notes	750		May 2015	May 2025	3.850%
October 2023 Notes	450		August 2013	October 2023	4.125%
November 2035 Notes	350		November 2005	November 2035	6.250%
January 2040 Notes	300		December 2009	January 2040	7.375%
	$	4,650

Our $4.050 billion of senior notes issued in 2009, 2013 and 2015 contain a change-in-control provision, which provides that each holder of the senior notes may require us to repurchase all or a portion of the notes at a price equal to 101 percent of the aggregate repurchased principal, plus accrued and unpaid interest, if a rating event, as defined in the indenture, occurs as a result of a change-in-control, as defined in the indenture. Any other credit rating changes may impact our borrowing cost, but do not require us to repay any borrowings.

The interest rate payable on our November 2035 Notes is currently 7.00 percent. Corporate credit rating improvements may result in a decrease in the adjusted interest rate on our November 2035 Notes to the extent that our lowest credit rating is above BBB- or Baa3. The interest rates on our November 2035 Notes will be permanently reinstated to the issuance rate if the lowest credit ratings assigned to these senior notes is either A- or A3 or higher.

Other Arrangements

We also maintain a $300 million credit and security facility secured by our U.S. trade receivables maturing on June 9, 2017. The credit and security facility requires that we maintain a maximum leverage covenant consistent with the 2015 Facility. The maximum leverage ratio requirement is 4.5 times and our actual leverage ratio as of December 31, 2015 is 3.0 times. We had no borrowings outstanding under this facility as of December 31, 2015 and December 31, 2014.

We have accounts receivable factoring programs in certain European countries that we account for as sales under ASC Topic 860, Transfers and Servicing. These agreements provide for the sale of accounts receivable to third parties, without recourse, of up to approximately $392 million as of December 31, 2015. We have no retained interests in the transferred receivables, other than collection and administrative responsibilities and, once sold, the accounts receivable are no longer available to satisfy creditors in the event of bankruptcy. We de-recognized $151 million of receivables as of December 31, 2015 at an average interest rate of 2.4 percent, and $167 million as of December 31, 2014 at an average interest rate of 3.2 percent.

In addition, we have uncommitted credit facilities with a commercial Japanese bank that provide for borrowings, promissory notes discounting and receivables factoring of up to 21.0 billion Japanese yen (approximately $175 million as of December 31, 2015). We de-recognized $132 million of notes receivable as of December 31, 2015 at an average interest rate of 1.6 percent and $134 million of notes receivable as of December 31, 2014 at an average interest rate of 1.8 percent. De-recognized accounts and notes receivable are excluded from trade accounts receivable, net in the accompanying consolidated balance sheets.

As of December 31, 2015, we had outstanding letters of credit of $44 million, as compared to $59 million as of December 31, 2014, which consisted primarily of bank guarantees and collateral for workers' compensation insurance arrangements. As of December 31, 2015 and 2014, none of the beneficiaries had drawn upon the letters of credit or guarantees; accordingly, we have not recognized a related liability for our outstanding letters of credit in our consolidated balance sheets as of December 31, 2015 or 2014. We believe we will generate sufficient cash from operations to fund these payments and intend to fund these payments without drawing on the letters of credit.
