On June 23, 2011, we amended and restated our multicurrency revolving credit agreement (the “Credit Facility”) to extend the facility’s expiration from May 14, 2012 to June 23, 2016 and reduce (at our direction) the facility size from $2.404 billion to $1.750 billion of aggregate effective borrowings. The material terms of the amended and restated Credit Facility are otherwise unchanged, and the facility continues to support general corporate needs, including working capital, capital expenditures, and letters of credit. The availability of the Credit Facility also supports our commercial paper program. Borrowings under the Credit Facility bear interest at LIBOR (the London Interbank Offered Rate) plus a spread, based on our public debt rating. We also pay quarterly fees on the Credit Facility at a rate based on our public debt rating. For additional information on our Credit Facility, including participating financial institutions, see Exhibit 10, “Second Amended and Restated Credit Agreement,” to our Current Report on Form 8-K filed with the SEC on June 27, 2011.
The Credit Facility contains certain covenants, including a single financial covenant that limits our maximum leverage (consisting of the ratio of Adjusted Total Debt to Consolidated EBITDA, each as defined in the Credit Facility) to not more than 4 to 1. Our outstanding public debt does not contain a corresponding financial covenant or a requirement that we maintain certain financial ratios. We currently satisfy the covenants in our Credit Facility and public debt instruments, including the leverage covenant under the Credit Facility, and do not expect the covenants to restrict our ability to meet our anticipated borrowing and guarantee levels or increase those levels should we decide to do so in the future.
We believe the Credit Facility and our access to capital markets, together with cash we expect to generate from operations, remains adequate to meet our short-term and long-term liquidity requirements, finance our long-term growth plans, meet debt service, and fulfill other cash requirements.
In early 2011 we resumed issuing commercial paper in the United States. We do not have purchase commitments from buyers for our commercial paper; therefore, our issuances are subject to market demand. We classify any outstanding commercial paper and Credit Facility borrowings as long-term debt based on our ability and intent to refinance it on a long-term basis. We reserve unused capacity under our Credit Facility to repay outstanding commercial paper borrowings in the event that the commercial paper market is not available to us for any reason when outstanding borrowings mature. We do not expect fluctuations in the demand for commercial paper to affect our liquidity, given our borrowing capacity under the Credit Facility.
At year-end 2011, our available borrowing capacity amounted to $1.520 billion and reflected borrowing capacity of $1.418 billion under our Credit Facility and our cash balance of $102 million. We calculated that borrowing capacity by taking $1.750 billion of effective aggregate bank commitments under our Credit Facility and subtracting $1 million of outstanding letters of credit under our Credit Facility and $331 million of outstanding commercial paper. We had no outstanding borrowings under our Credit Facility at year-end 2011. We anticipate that available borrowing capacity under the Credit Facility will be adequate to fund our liquidity needs, including repayment of debt obligations. Since we continue to have ample flexibility under the Credit Facility’s covenants, we also expect that undrawn bank commitments under the Credit Facility will remain available to us even if business conditions were to deteriorate markedly.
