Credit Facilities

In August 2011, we entered into a senior secured credit facility (2011 credit facility), which replaced the senior secured credit facility we entered into in 2007 (2007 credit facility). The 2011 credit facility consists of a $300 million U.S. dollar term loan (the term loan) and a multicurrency revolving line of credit (the revolver) with a principal amount of up to $660 million. Both the term loan and the revolver mature on August 8, 2016, and amounts borrowed under the revolver are classified as long-term. Amounts borrowed under the revolver during the credit facility term may be repaid and reborrowed until the revolver's maturity, at which time the revolver will terminate, and all outstanding loans, together with all accrued and unpaid interest, must be repaid. Amounts not borrowed under the revolver are subject to a commitment fee, which is paid in arrears on the last day of each fiscal quarter, ranging from 0.20% to 0.40% per annum depending on our total leverage ratio as of the most recently ended fiscal quarter. Amounts repaid on the term loan may not be reborrowed. The 2011 credit facility permits us and certain of our foreign subsidiaries to borrow in U.S. dollars, euros, British pounds, or, with lender approval, other currencies readily convertible into U.S. dollars. All obligations under the 2011 credit facility are guaranteed by Itron, Inc. and material U.S. domestic subsidiaries and are secured by a pledge of substantially all of the assets of Itron, Inc. and material U.S. domestic subsidiaries, including a pledge of 100% of the capital stock of material U.S. domestic subsidiaries and up to 66% of the voting stock (100% of the non-voting stock) of their first-tier foreign subsidiaries. In addition, the obligations of any foreign subsidiary who is a foreign borrower, as defined by the 2011 credit facility, are guaranteed by the foreign subsidiary and by its direct and indirect foreign parents. The 2011 credit facility includes debt covenants, which contain certain financial thresholds and place certain restrictions on the incurrence of debt, investments, and the issuance of dividends. We were in compliance with the debt covenants under the 2011 credit facility at December 31, 2013.

Scheduled principal repayments for the term loan are due quarterly in the amounts of $5.6 million through June 2014, $7.5 million from September 2014 through June 2016, and the remainder due at maturity on August 8, 2016. The term loan may be repaid early in whole or in part, subject to certain minimum thresholds, without penalty.

Required minimum principal payments on our outstanding credit facilities are as follows:

Under the 2011 credit facility, we elect applicable market interest rates for both the term loan and any outstanding revolving loans. We also pay an applicable margin, which is based on our total leverage ratio (as defined in the credit agreement). The applicable rates per annum may be based on either: (1) the LIBOR rate, plus an applicable margin, or (2) the Alternate Base Rate, plus an applicable margin. The Alternate Base Rate election is equal to the greatest of three rates: (i) the prime rate, (ii) the Federal Reserve effective rate plus 1/2 of 1%, or (iii) one month LIBOR plus 1%. At December 31, 2013, the interest rate for both the term loan and the revolver was 1.67% (the LIBOR rate plus a margin of 1.50%).

At December 31, 2013, $120 million was outstanding under the 2011 credit facility revolver, and $49.5 million was utilized by outstanding standby letters of credit, resulting in $490.5 million available for additional borrowings.

Prepaid debt fees of approximately $897,000 were capitalized in the second quarter of 2012 associated with the increase in the revolver in April 2012. At December 31, 2013 and 2012, unamortized prepaid debt fees were as follows:

Convertible Senior Subordinated Notes

On August 1, 2011, in accordance with the terms of the convertible senior subordinated notes (convertible notes), we repurchased $184.8 million of the convertible notes at their principal amount plus accrued and unpaid interest. On September 30, 2011, we redeemed the remaining $38.8 million of the convertible notes, plus accrued and unpaid interest.

The convertible notes were separated between the liability and equity components using our estimated non-convertible debt borrowing rate at the time the convertible notes were issued, which was determined to be 7.38%. This rate also reflected the effective interest rate on the liability component for all periods during which the convertible notes were outstanding. The carrying amount of the equity component of $31.8 million is retained as a permanent component of our shareholders' equity, and no gain or loss was recognized upon derecognition of the convertible notes as the fair value of the consideration transferred to the holders equaled the fair value of the liability component.

The discount on the liability component was fully amortized by the end of the second quarter of 2011. The interest expense relating to both the contractual interest coupon and amortization of the discount on the liability component is as follows:
