Credit Facilities

On June 23, 2015, we entered into an amended and restated credit agreement providing for committed credit facilities in the amount of $725 million U.S. dollars (the 2015 credit facility). The 2015 credit facility consists of a $225 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 $500 million. The revolver also contains a $300 million standby letter of credit sub-facility and a $50 million swingline sub-facility (available for immediate cash needs at a higher interest rate). Both the term loan and the revolver mature on June 23, 2020, and amounts borrowed under the revolver are classified as long-term and, 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 0.18% to 0.30% 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 2015 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 2015 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 2015 credit facility, are guaranteed by the foreign subsidiary and by its direct and indirect foreign parents.

The 2015 credit facility includes debt covenants, which contain certain financial ratio thresholds, place certain restrictions on the incurrence of debt, investments, and the issuance of dividends, and require quarterly unaudited and annual audited financial reporting. We were not in compliance with the financial reporting portion of these covenants under the 2015 credit facility at March 31, 2016. We have been granted waivers which extend the due dates for annual audited financial statements and quarterly unaudited financial statements through September 12, 2016.

Scheduled principal repayments for the term loan are due quarterly in the amount of $2.8 million through June 2017, $4.2 million from September 2017 through June 2018, $5.6 million from September 2018 through March 2020, and the remainder due at maturity on June 23, 2020. 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:



Year Ending December 31,	Minimum Payments
	(in thousands)
2016	$	11,250
2017	14,063
2018	19,687
2019	22,500
2020	303,712
Total minimum payments on debt	$	371,212

Under the 2015 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 or EURIBOR rate (floor of 0%), 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, 2015, the interest rate for both the term loan and the USD revolver was 2.18% (the LIBOR rate plus a margin of 1.75%), and the interest rate for the EUR revolver was 1.75% (the EURIBOR floor rate plus a margin of 1.75%).

⁽¹⁾	We borrowed $113.5 million, $47.7 million, and $35.0 million under the multicurrency revolving line of credit during 2015, 2014 and 2013, respectively.

At December 31, 2015, $151.8 million was outstanding under the 2015 credit facility revolver, and $46.6 million was utilized by outstanding standby letters of credit, resulting in $301.6 million available for additional borrowings or standby letters of credit. At December 31, 2015, $253.4 million was available for additional standby letters of credit under the letter of credit sub-facility and no amounts were outstanding under the swingline sub-facility.

Upon entering into the 2015 credit facility, a portion of our unamortized prepaid debt fees, totaling $821,000, were written off to interest expense. Prepaid debt fees of approximately $3.9 million were capitalized associated with the 2015 credit facility. Total unamortized prepaid debt fees were as follows:
