some of our management contracts require us to make substantial initial expenditures of cash in connection with opening or renovating a facility. Generally, these initial expenditures are subsequently fully or partially recoverable as pass-through costs or are billable as a component of the per diem rates or monthly fixed fees to the contracting agency over the original term of the contract. In connection with GEOAmey, our joint venture in the United Kingdom, we and our joint venture partner have each provided a line of credit of £12 million, or $15.6 million, based on exchange rates as of September 30, 2018, for GEOAmey’s operations. As of September 30, 2018, $1.7 million was outstanding to each of the joint venture partners. In October 2018, the note receivable to each joint venture partner was paid off in full.
We currently have contractual commitments for a number of projects using Company financing. We estimate that the cost of these existing capital projects will be approximately $229.4 million of which $188.7 million was spent through September 30, 2018. We estimate that the remaining capital requirements related to these capital projects will be $40.7 million which will be spent through 2019.

On April 30, 2018, we entered into Amendment No. 1 to Third Amended and Restated Credit Agreement (the “Credit Agreement”) by and among the Refinancing Lenders party thereto, the other lenders party thereto, GEO and GEO Corrections Holdings, Inc. and BNP Paribas, as Administrative Agent. The amendment, among other things, provides for the refinancing of all of GEO’s existing senior secured term loans with refinancing term loans in the aggregate principal amount of $792.0 million and makes certain other modifications to GEO’s senior secured credit agreement. The interest rate applicable to the refinancing term loans is equal to LIBOR plus 2.00% (with a LIBOR floor of 0.75%). The amendment was considered to be a modification and loan costs of approximately $1 million were incurred and capitalized in connection with the transaction.
The Credit Agreement evidences a credit facility (the “Credit Facility”) consisting of a $792.0 million term loan (the “Term Loan”) bearing interest at LIBOR plus 2.00% (with a LIBOR floor of 0.75%), and a $900.0 million Revolver initially bearing interest at LIBOR plus 2.25% (with no LIBOR floor) together with AUD275 million under the Australian LC Facility. As of September 30, 2018, there were no letters of credit issued under the Australian LC Facility. Amounts to be borrowed by GEO under the Credit Agreement are subject to the satisfaction of customary conditions to borrowing. The Term Loan component is scheduled to mature on March 23, 2024. The revolving credit commitment component is scheduled to mature on May 19, 2021. The Credit Agreement also has an accordion feature of $450.0 million, subject to lender demand and prevailing market conditions and satisfying the relevant borrowing conditions.
