        Loans payable at December 31, 2012 and 2011 were $16 million and $28 million, respectively, and consisted primarily of notes payable to financial institutions. The weighted-average interest rate for notes payable, bank overdrafts and current maturities of long-term debt at December 31, 2012, 2011 and 2010, was as follows:

Interest

        For the years ended December 31, 2012, 2011 and 2010, total interest incurred was $39 million, $48 million and $45 million, respectively. For the same respective periods, interest capitalized was $7 million, $4 million and $5 million.

Revolving Credit Facility

        On November 9, 2012, we entered into a five-year revolving credit agreement with a syndicate of lenders. The credit agreement provides us with a $1.75 billion senior unsecured revolving credit facility, the proceeds of which are to be used by us for working capital or other general corporate purposes.

        The credit facility matures on November 9, 2017. Amounts payable under our revolving credit facility will rank pro rata with all of our unsecured, unsubordinated indebtedness. Up to $200 million under our credit facility is available for swingline loans denominated in U.S. dollars. Advances under the facility bear interest at (i) a base rate or (ii) a rate equal to the LIBOR Rate plus an applicable margin based on the credit ratings of our outstanding senior unsecured long-term debt. Based on our current long-term debt ratings, the applicable margin on LIBOR Rate loans was 0.875 percent per annum as of December 31, 2012. Advances under the facility may be prepaid without premium or penalty, subject to customary breakage costs.

        The credit agreement includes various covenants, including, among others, maintaining a leverage ratio of no more than 3.25 to 1.0. As of December 31, 2012, we were in compliance with the covenants.

        The table below is a reconciliation of the maximum capacity of our revolver to the amount available under the facility as of December 31, 2012. There were no outstanding borrowings under this facility at December 31, 2012.

        As of December 31, 2012, we also had $301 million available for borrowings under our international and other domestic short-term credit facilities. Commitments against the other domestic and international facilities were $16 million as of December 31, 2012 and $28 million at the end of 2011.

Long-term Debt

        Principal payments required on long-term debt during the next five years are:

        Interest on the 6.75% debentures is payable on February 15 and August 15 each year.

        Interest on the $250 million 7.125% debentures and $165 million 5.65% debentures is payable on March 1 and September 1 of each year. The debentures are unsecured and are not subject to any sinking fund requirements. We can redeem the 7.125% debentures and the 5.65% debentures at any time prior to maturity at the greater of par plus accrued interest or an amount designed to ensure that the debenture holders are not penalized by the early redemption.

        During 2010, two of our wholly-owned Brazilian subsidiaries entered into a loan agreement for a loan in local currency in an amount equivalent to US $50 million, at drawdown, at a fixed rate of 4.5 percent to finance its exports over the next three years. The principal of the loan had a two-year grace period and began amortizing in 2012.

        During 2009, one wholly-owned subsidiary, Cummins Brasil Ltda, entered into a loan agreement with the Brazil development bank, BNDES, for a loan in local currency in an amount equivalent to US $45 million, at drawdown, at a fixed rate of 4.5 percent to finance its exports over the next three years. The principal of the loan had a two-year grace period which began amortizing in 2011 and was completed in August of 2012.

        Our debt agreements contain several restrictive covenants. The most restrictive of these covenants applies to our revolving credit facility which will upon default, among other things, limit our ability to incur additional debt or issue preferred stock, enter into sale-leaseback transactions, sell or create liens on our assets, make investments and merge or consolidate with any other person. In addition, we are subject to a maximum debt-to-EBITDA ratio financial covenant. As of December 31, 2012, we were in compliance with all of the covenants under our borrowing agreements.
