On December 9, 2015, the Company entered into a new $800 million revolving credit facility (the “KCS Revolving Credit Facility”) pursuant to a Credit Agreement, dated December 9, 2015 (the “Credit Agreement”), among the Company, certain of its wholly-owned domestic subsidiaries named therein as guarantors, the various financial institutions and other persons from time to time parties thereto as lenders and/or issuing banks (the “Lenders”) and Bank of America, N.A., as administrative agent for the Lenders (“Agent”). The commitments of the lenders under the existing revolving credit facilities of each of The Kansas City Southern Railway Company (“KCSR”) and Kansas City Southern de México, S.A. de C.V. (“KCSM”) were terminated, and all indebtedness and other obligations outstanding thereunder were repaid in full.

The KCS Revolving Credit Facility provides the Company with a five-year $800 million revolving credit facility consisting of (i) a revolving facility in an amount up to $800 million and (ii) a standby letter of credit facility in an amount up to $25 million which shall constitute usage under the revolving facility.

The outstanding principal balance of loans under the KCS Revolving Credit Facility bear interest at floating rates. At the Company’s option, the loans bear interest at a rate equal to (i) LIBOR plus the applicable margin (which, depending on the Company’s credit ratings, will be between 1.125% to 2.00%) (the “Applicable Margin”) or (ii) the Base Rate (to be defined as the highest of (a) the federal funds rate plus  ¹⁄₂ of 1%, (b) the Bank of America prime rate and (c) one-month LIBOR plus 1.00%) plus the Applicable Margin; provided that, with respect to the loans under the KCS Revolving Credit Facility, LIBOR shall at no time be less than zero.

Each guarantor has guaranteed repayment of the amounts due under the KCS Revolving Credit Facility.

The Company has given certain representations and warranties that are customary for credit agreements of this type. The KCS Revolving Credit Facility contains affirmative and negative covenants that are customary for credit agreements of this type, including financial maintenance covenants related to a leverage ratio and an interest coverage ratio (each as defined in the Credit Agreement).

Events of default under the KCS Revolving Credit Facility are customary for transactions of this type and include, without limitation, non-payment of obligations, breach of any representation or warranty, non-performance of covenants and obligations, default on other indebtedness, certain judgments rendered, change of control, bankruptcy or insolvency events, customary ERISA defaults and the revocation, termination, abrogation, appropriation or repudiation by any person of the Concession Title (as defined in the Credit Agreement), or abandonment of the Concession Title by KCSM. The occurrence of an event of default could result in the termination of the commitments and the acceleration of the repayment of any outstanding principal balance of the KCS Revolving Credit Facility.

The above description of the Credit Agreement is qualified in its entirety by the full text of the agreement, attached hereto as Exhibit 10.1.
