On September 12, 2017, Allegion plc (the “Company”) entered into a new Credit Agreement (the “Credit Agreement”) by and among the Company and Allegion US Holding Company Inc. (“Allegion US Holding” and together with the Company, the “Borrowers”), as Borrowers, the lenders and issuing banks party thereto, and JPMorgan Chase Bank, N.A., as administrative agent. The Credit Agreement refinanced in full the Company’s and Allegion US Holding’s existing Second Amended and Restated Credit Agreement, dated as of September 30, 2015 (the “Existing Credit Agreement”), among the Company, Allegion US Holding, the lenders and issuing banks party thereto, and JPMorgan Chase Bank, N.A., as administrative agent and collateral agent. The Credit Agreement provides for $1,200.0 million in unsecured financing, consisting of a term loan facility (the “Term Facility”) and a revolving credit facility (the “Revolving Facility” and, together with the Term Facility, the “Facilities”).

The Term Facility consists of a five-year term loan A facility in an aggregate principal amount of $700.0 million. The full amount of the Term Facility was made in a single drawing on September 12, 2017, and amounts borrowed under the Term Facility that are repaid or prepaid may not be reborrowed. The Term Facility will amortize in quarterly installments at the following rates per annum: 5% in year one; 5% in year two; 5% in year three and 10% in year four and thereafter, with the balance due on the date that is five years after the closing date.

The Revolver consists of a five-year revolving credit facility with aggregate commitments in an amount equal to $500.0 million, of which up to $100.0 million is available for the issuance of letters of credit, and including a swingline facility in an amount equal to $50.0 million. Certain of the commitments under the Revolver are available to be drawn in currencies other than US dollars, including euros and pounds sterling. The Revolver will mature and the commitments thereunder will terminate on the date that is five years after the Escrow Date. Amounts repaid under the Revolver may be reborrowed.

The indebtedness, obligations and liabilities under the Facilities are unconditionally guaranteed jointly and severally on an unsecured basis by the Company and Allegion US Holding and are unsecured.

Prior to maturity, the Borrowers are only required to prepay the Revolving Facility in the event that the loans outstanding under the Revolving Facility (inclusive of any letters of credit issued) exceed the relevant commitments thereof. The Borrowers are not required to prepay the Term Facility at any point prior to maturity. The Borrowers may voluntarily prepay outstanding loans under the Facilities in whole or in part at any time without premium or penalty, subject to the payment of customary breakage costs in the case of LIBOR rate loans. Voluntary prepayments of the Term Facility will be applied to the remaining installments thereof at the direction of the Borrowers while voluntary prepayments of the Revolving Facility will be applied ratably among the lenders thereof. Commitments under the Revolving Facility may be reduced in whole or in part at any time without premium or penalty.

The Facilities contain negative and affirmative covenants and events of default customary for credit facilities of this type.

Outstanding borrowings under the Facilities will accrue interest, at the option of the Borrowers, at a per annum rate of (i) a LIBOR rate plus the applicable spread or (ii) a base rate plus the applicable spread. The applicable margin for borrowings under the Facilities is subject to a ratings-based pricing grid with the LIBOR rate ranging from 1.125% to 1.500%, depending on the Borrowers’ credit ratings. During an event of default, overdue principal under the Facilities may bear interest at a rate 2.00% in excess of the otherwise applicable rate of interest.

The Borrower will pay certain fees with respect to the Facilities, including an unused commitment fee on the undrawn portion of the Revolving Facility of between 0.125% and 0.200%, depending on Borrowers’ credit rating, as well as certain other fees.

The summary is qualified in its entirety by reference to the Credit Agreement filed as Exhibit 10.1 to this Current Report on Form 8-K, which is incorporated herein by reference.

On September 12, 2017, concurrently with the effectiveness of the Credit Agreement described above under Item 1.01, all obligations under the Existing Credit Agreement were satisfied, all commitments thereunder were terminated and all guarantees and security interests that had been granted in connection therewith were released.

The information in Item 1.01 and Item 1.02 of this Current Report on Form 8-K is incorporated by reference into this Item 2.03.
