The amendment reduces the interest rate applicable to the outstanding loan by 1.50%. Under the terms of the amendment, the interest rate on the outstanding loan is based, at our option, on an adjusted Eurodollar Rate, plus a margin of 4.00%, or a Base Rate, plus a margin of 3.00%. In connection with the amendment, we paid a consent fee equal to 0.25% of the aggregate principal amount, a call protection fee equal to 1.00% of the aggregate principal amount, and certain other fees.Senior NotesIn October 2009, we completed the sale of $1.0 billion aggregate principal amount of our Senior Notes. In March 2013, we completed the sale of an additional $300 million aggregate principal amount of Senior Notes. In January 2017, we issued an additional $250 million aggregate principal amount of Senior Notes. Interest related to the Senior Notes is payable on May 1 and November 1 of each year until the maturity date of November 1, 2021. The Senior Notes are senior unsecured obligations of the Company.We received net proceeds of approximately $250 million from the January 2017 issuance of additional Senior Notes, which included accrued interest of $4 million, offset by underwriter fees of $4 million. The debt issuance costs were recorded as a direct deduction from the carrying amount of the Senior Notes and will be amortized through Interest expense. The debt issuance costs will be amortized over the remaining life of the Senior Notes. As a result of the transaction, the effective interest rate of the Senior Notes is now 8.5%. The proceeds from the January 2017 sale of additional Senior Notes will be used for general corporate purposes, including working capital and capital expenditures.Financial Services OperationsAsset-backed DebtIn November 2016, the maturity date of the variable funding notes ("VFN") facility was extended from May 2017 to November 2017, and the maximum capacity was reduced from $500 million to $450 million. The VFN facility is secured by assets of the wholesale note owner trust.In December 2016, Truck Retail Accounts Corporation ("TRAC"), one of our consolidated SPEs, renewed its $100 million revolving facility to October 2017. Borrowings under this facility are secured by eligible retail accounts receivable.Bank Credit FacilitiesIn May 2016, NFC amended and extended its 2011 bank credit facility which was originally due in December 2016. The 2016 amendment extended the maturity date to June 2018 and initially reduced the revolving portion of the facility from $500 million to $400 million. In December 2016, and in accordance with the amendment, the revolving portion of the facility was reduced to a maximum of $275 million, the term loan portion of the facility was paid down to $82 million, and the quarterly principal payments were reduced from $9 million to $2 million. The borrowings on the revolving portion of the facility totaled $244 million as of January 31, 2017. The balance of the term loan portion of the facility was $82 million as of January 31, 2017. The amendment allows NFC to increase revolving or term loan commitments, subject to obtaining commitments from existing or new lenders to provide additional or increased revolving commitments and/or additional term loans, to permit a maximum total facility size of $700 million after giving effect to any such increase and without taking into account the non-extended loans and commitments.Commercial PaperEffective February 2017, our Mexican financial services operation entered into a five-year commercial paper program for up to ₱1.8 billion (the equivalent of approximately US$86 million at January 31, 2017). This program replaced the program that matured in December 2016. |
