On September 27, 2018, we entered into a Credit Agreement, by and among us, Garrett LX I S.à r.l., Garrett LX II S.à r.l. (“Lux Guarantor”), Garrett LX III S.à r.l. (“Lux Borrower”), Garrett Borrowing LLC (in such capacity, the “US Co-Borrower”), and Honeywell Technologies Sàrl (“Swiss Borrower” and, together with Lux Borrower and US Co-Borrower, the “Borrowers”), the lenders and issuing banks party thereto and JPMorgan Chase Bank, N.A., as administrative agent (the “Credit Agreement”).

The Credit Agreement provides for senior secured financing of approximately the Euro equivalent of $1,254 million, consisting of (i) a seven-year senior secured first-lien term B loan facility, which consists of a tranche denominated in Euro of €375 million and a tranche denominated in U.S. Dollars of $425 million (the “Term B Facility”), (ii) five-year senior secured first-lien term A loan facility in an aggregate principal amount of €330 million (the “Term A Facility” and, together with the Term B Facility, the “Term Loan Facilities”) and (iii) a five-year senior secured first-lien revolving credit facility in an aggregate principal amount of €430 million with revolving loans to Swiss Borrower, to be made available in a number of currencies including Australian Dollars, Euros, Pounds Sterling, Swiss Francs, U.S. Dollars and Yen (the “Revolving Facility” and, together with the Term Loan Facilities, the “Senior Credit Facilities”). Each of the Revolving Facility and the Term A Facility matures five years after the effective date of the Credit Agreement, in each case with certain extension rights in the discretion of each lender. The Term B Facility matures seven years after the effective date of the Credit Agreement, with certain extension rights in the discretion of each lender.

The Senior Credit Facilities are subject to an interest rate, at our option, of either (a) base rate determined by reference to the highest of (1) the rate of interest last quoted by The Wall Street Journal as the “prime rate” in the United States, (2) the greater of the federal funds effective rate and the overnight bank funding rate, plus 0.5% and (3) the one month adjusted LIBOR rate, plus 1% per annum (“ABR”), (b) an adjusted LIBOR rate (“LIBOR”) (which shall not be less than zero), or (c) an adjusted EURIBOR rate (“EURIBOR”) (which shall not be less than zero), in each case, plus an applicable margin. The applicable margin for the U.S. Dollar tranche of the Term B Facility is currently 2.50% per annum (for LIBOR loans) and 1.50% per annum (for ABR loans) while that for the Euro tranche of the Term B Facility is currently 2.75% per annum (for EURIBOR loans). The applicable margin for each of the Term A Facility and the Revolving Credit Facility varies based on our leverage ratio. Accordingly, the interest rates for the Senior Credit Facilities will fluctuate during the term of the Credit Agreement based on changes in the ABR, LIBOR, EURIBOR or future changes in our leverage ratio. Interest payments with respect to the Term Loan Facilities are required either on a quarterly basis (for ABR loans) or at the end of each interest period (for LIBOR and EURIBOR loans) or, if the duration of the applicable interest period exceeds three months, then every three months.

We are obligated to make quarterly principal payments throughout the term of the Term Loan Facilities according to the amortization provisions in the Credit Agreement. Borrowings under the Credit Agreement are prepayable at our option without premium or penalty. We may request to extend the maturity date of all or a portion of the Senior Credit Facilities subject to certain conditions customary for financings of this type. The Credit Agreement also contains certain mandatory prepayment provisions in the event that we incur certain types of indebtedness or receive net cash proceeds from certain non-ordinary course asset sales or other dispositions of property, in each case subject to terms and conditions customary for financings of this type.

On May 23, 2019, the Company made a prepayment of the Euro-equivalent of $14 million related to the mandatory amortizations of its Term Loan A Facility due in the third and fourth quarters of 2019. On September 27, 2019, the Company made a prepayment of the Euro-equivalent of $41 million related to the mandatory amortizations of its Term Loan A Facility due through the first half of 2021. On December 27, 2019, the Company made a prepayment of the Euro-equivalent of $23 million related to the mandatory amortizations of its Term Loan A Facility due through the end of 2021.

On December 27, 2019, the Company made a principal repayment of the Euro-equivalent of $76 million on the Euro denominated Term Loan B Facility.

The Credit Agreement contains certain affirmative and negative covenants customary for financings of this type that, among other things, limit our and our subsidiaries’ ability to incur additional indebtedness or liens, to dispose of assets, to make certain fundamental changes, to enter into restrictive agreements, to make certain investments, loans, advances, guarantees and acquisitions, to prepay certain indebtedness and to pay dividends, to make other distributions or redemptions/ repurchases, in respect of the our and our subsidiaries’ equity interests, to engage in transactions with affiliates, amend certain material documents or to permit the International Financial Reporting Standards equity amount of Lux Borrower to decrease below a certain amount. The Credit Agreement also contains financial covenants requiring the maintenance of a consolidated total leverage ratio of not greater than 4.00 to 1.00 (with step downs to (i) 3.75 to 1.00 in September 2020 and (ii) 3.50 to 1.00 in September 2021), and a consolidated interest coverage ratio of not less than 2.75 to 1.00. We are in compliance with our financial covenants as of December 31, 2019.

On September 27, 2018, we completed the offering of €350 million (approximately $400 million) in aggregate principal amount of 5.125% senior notes due 2026 (the “Senior Notes”). The Senior Notes bear interest at a fixed annual interest rate of 5.125% and mature on October 15, 2026.

The Senior Notes were issued pursuant to an Indenture, dated September 27, 2018 (the “Indenture”), which, among other things and subject to certain limitations and exceptions, limits our ability and the ability of our restricted subsidiaries to: (i) incur, assume or guarantee additional indebtedness or issue certain disqualified equity interests and preferred shares, (ii) pay dividends or distributions on, or redeem or repurchase, capital stock and make other restricted payments, (iii) make investments, (iv) consummate certain asset sales or transfers, (v) engage in certain transactions with affiliates, (vi) grant or assume certain liens on assets to secure debt unless the Senior Notes are secured equally and ratably (vii) restrict dividends and other payments by certain of their subsidiaries and (vii) consolidate, merge, sell or otherwise dispose of all or substantially all of our or our restricted subsidiaries’ assets.

All debt issuance costs, except for those associated to the Revolving Credit Facility, are deferred and recognized as a direct deduction to the related debt liability and are amortized to interest expense over the debt term. The company paid approximately $37 million of debt issuance costs in connection with the Term A Facility, Term B Facility, and Senior Notes.

The unutilized portion of the Revolving Credit Facility is subject to an annual commitment fee of 0.40% to 0.50% depending on the Company’s consolidated leverage ratio. Debt issuance costs associated with the Revolving Credit Facility were capitalized in Other assets and are amortized to interest expense over the debt term. Approximately, $6 million of debt issuance costs were paid in connection with the Revolving Credit Facility.
