On October 16, 2017, TerraForm Power entered into a credit agreement (the “Sponsor Line”) with Brookfield and one of its affiliates. The Sponsor Line establishes a $500.0 million secured revolving credit facility and provides for the lenders to commit to make LIBOR loans to the Company during a period not to exceed three years from the effective date of the Sponsor Line (subject to acceleration for certain specified events). The Company may only use the revolving Sponsor Line credit facility to fund all or a portion of certain funded acquisitions or growth capital expenditures. The Sponsor Line will terminate, and all obligations thereunder will become payable, no later than October 16, 2022.
Borrowings under the Sponsor Line bear interest at a rate per annum equal to a LIBOR rate determined by reference to the costs of funds for U.S. dollar deposits for the interest period relevant to such borrowing adjusted for certain additional costs, in each case plus 3.00% per annum. In addition to paying interest on outstanding principal under the Sponsor Line, the Company is required to pay a standby fee of 0.50% per annum in respect of the unutilized commitments thereunder, payable quarterly in arrears. The Company is permitted to voluntarily reduce the unutilized portion of the commitment amount and repay outstanding loans under the Sponsor Line at any time without premium or penalty, other than customary “breakage” costs. TerraForm Power’s obligations under the Sponsor Line are secured by first-priority security interests in substantially all assets of TerraForm Power, including 100% of the capital stock of Terra LLC, in each case subject to certain exclusions set forth in the credit documentation governing the Sponsor Line. Under certain circumstances, the Company may be required to prepay amounts outstanding under the Sponsor Line.
During the year ended December 31, 2018 the Company made two draws on the Sponsor Line totaling $86 million that were used to fund the acquisition of Saeta which were repaid in full as of December 31, 2018. The Company did not make any draws on the Sponsor Line during the year ended December 31, 2017.
Covenants and Cross-defaults
The terms of the Company's corporate-level debt agreements and indentures include customary affirmative and negative covenants and provide for customary events of default, which include, among others, nonpayment of principal or interest and failure to timely deliver financial statements. This includes quarterly financial maintenance covenants for the Revolver. The occurrence of an event of default for one corporate-level debt instrument could also cause a cross-default for the other corporate-level debt instruments, as described below.
Pursuant to both the terms of the Revolver and the Term Loan, a default of more than $75.0 million of indebtedness (other than non-recourse indebtedness, and indebtedness under the Sponsor Line, which is an obligation of the Company), including under these respective agreements, would result in a cross-default under the respective agreements that would permit the lenders holding more than 50% of the aggregate exposure under each to accelerate any outstanding principal amount of loans, terminate any outstanding letter of credit and terminate the outstanding commitments (as applicable to each).
Pursuant to the terms of each series of the Senior Notes, a default of indebtedness that exceeds the greater of $100.0 million or 1.5% of the Company’s consolidated total assets (other than non-recourse indebtedness and indebtedness under the Sponsor Line, which is an obligation of TerraForm Power), that is (i) caused by a failure to pay principal of, or interest or premium, if any, on such indebtedness prior to the expiration of the grace period provided in such indebtedness on the date of such default or (ii) results in the acceleration of such indebtedness would give the trustee under the respective indentures or the holders of at least 25% in the aggregate principal amount of the then outstanding Senior Notes under the respective indentures the right to accelerate any outstanding principal amount of loans and terminate the outstanding commitments under the respective indentures.
An event of default of more than $75.0 million of indebtedness under the Revolver, Term Loan and each series of the Senior Notes would trigger an event of default under the Sponsor Line that would permit the lenders to accelerate any outstanding principal amount of loans and terminate the outstanding commitments under the Sponsor Line.
In relation to the acquisition of Saeta, as discussed in Note 4. Acquisitions and Dispositions, the Company assumed total indebtedness of $1.91 billion predominantly comprised of non-recourse project financing from commercial banks secured by Saeta’s solar and wind power plants. As of December 31, 2018 the Company obtained all required change of control consents in respect of this indebtedness. The interest rates applicable to this assumed indebtedness ranged between 1.1% and 5.7% as of December 31, 2018.
