We had total debt of $4.254 billion as of March 31, 2013 and $4.256 billion as of December 31, 2012. The debt maturity schedule for the significant components of our debt obligations as of March 31, 2013 is as follows:

Revolving Credit Facility

We maintain a $2.000 billion revolving credit facility, maturing in April 2017, with a global syndicate of commercial banks. Eurodollar and multicurrency loans under this revolving credit facility bear interest at LIBOR plus an interest margin of between 0.875 percent and 1.475 percent, based on our corporate credit ratings and consolidated leverage ratio (1.275 percent as of March 31, 2013). 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 (0.225 percent as of March 31, 2013). There were no amounts borrowed under our revolving credit facility as of March 31, 2013 or December 31, 2012.

As of March 31, 2013, we had outstanding letters of credit of $93 million, as compared to $94 million as of December 31, 2012, which consisted primarily of bank guarantees and collateral for workers' compensation insurance arrangements. As of March 31, 2013 and December 31, 2012, none of the beneficiaries had drawn upon the letters of credit or guarantees; accordingly, we had not recognized a related liability for our outstanding letters of credit in our consolidated balance sheets as of March 31, 2013 or December 31, 2012. 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.

Our revolving credit facility agreement in place as of March 31, 2013 requires that we maintain certain financial covenants, as follows:



	Covenant Requirement	Actual as of March 31, 2013
Maximum leverage ratio (1)	3.5 times	2.4 times
Minimum interest coverage ratio (2)	3.0 times	6.9 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 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 up to $500 million in restructuring charges and restructuring-related expenses related to our current or future restructuring plans. As of March 31, 2013, we had $343 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 shall not exceed $2.300 billion in the aggregate. As of March 31, 2013, we had approximately $2.3 billion of the combined legal and debt exclusion remaining. As of and through March 31, 2013, 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 facilities 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.

Senior Notes

We had senior notes outstanding of $4.200 billion as of March 31, 2013 and December 31, 2012. These notes are publicly registered securities, 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 and liabilities of our subsidiaries (see Other Arrangements below).

Other Arrangements

We also maintain a $350 million credit and security facility secured by our U.S. trade receivables. In June 2012, we extended the maturity of this facility to June 2013, subject to further extension. There were no borrowings under this facility as of March 31, 2013 and December 31, 2012.

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 $290 million as of March 31, 2013. 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 $188 million of receivables as of March 31, 2013 at an average interest rate of 3.8 percent, and $191 million as of December 31, 2012 at an average interest rate of 1.6 percent. Within Italy, Spain, Portugal and Greece the number of days our receivables are outstanding has increased above historical levels. We believe we have adequate allowances for doubtful accounts related to our Italy, Spain, Portugal and Greece accounts receivable; however, we will continue to monitor the European economic environment for any collectibility issues related to our outstanding receivables. As of March 31, 2013, our net receivables in these countries greater than 180 days past due totaled $55 million, of which $16 million were past due greater than 365 days. In addition, we are currently pursuing alternative factoring providers and financing arrangements to mitigate our credit exposure to receivables in this region.

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 $223 million as of March 31, 2013). We de-recognized $165 million of notes receivable as of March 31, 2013 at an average interest rate of 1.8 percent and $182 million of notes receivable as of December 31, 2012 at an average interest rate of 1.6 percent. De-recognized accounts and notes receivable are excluded from trade accounts receivable, net in the accompanying unaudited condensed consolidated balance sheets.
