Item 1.01
Entry into a Material Definitive Agreement
On December 20, 2018 (the “Closing Date”), Sunrun Inc.’s (“Sunrun”) indirectly wholly-owned subsidiary, Sunrun Athena Issuer 2018-1, LLC (“Sunrun Athena”), completed an issuance of Solar Asset Backed Notes (the “Transaction”).
Sunrun Athena issued Solar Asset Backed Notes, Series 2018-1, Class A (the “Class A Notes”) in an aggregate principal amount of $322,000,000 at an issue price of $317,250,770, representing an original issue discount of approximately 1.47%.  The Class A Notes bear interest at a rate of 5.31% and have a rated final maturity of April 30, 2049.    
The Class A Notes may only be acquired by persons who are either (i) qualified institutional buyers as defined in Rule 144A under the Securities Act of 1933, as amended (the “Securities Act”), or (ii) not U.S. Persons (as defined in Regulation S under the Securities Act (“Regulation S”)) in offshore transactions in reliance on Regulation S.  The Class A Notes have been rated A- (sf) by Kroll Bond Rating Agency, Inc.  
The Collateral
 The Class A Notes were issued by Sunrun Athena pursuant to an Indenture (the “Indenture”), dated as of the Closing Date, between Sunrun Athena and Wells Fargo Bank, National Association (“Indenture Trustee”), as indenture trustee.  
 The Class A Notes are secured by, and payable solely from the cash flow generated by, the managing membership interests that are wholly-owned by Sunrun Athena. Each managing member owns an interest in a project company. Each project company owns (or, in the case of one such project company, leases) a pool of photovoltaic systems and related leases and power purchase agreements and ancillary rights and agreements that were originated (or in certain circumstances acquired) by Sunrun.  With the exception of one project company (which is indirectly wholly-owned by Sunrun Athena), each project company is jointly owned with a third party investor.
 Sunrun (in such capacity, the “Transaction Manager”) will act as transaction manager pursuant to the terms of a Transaction Management Agreement between Sunrun and Sunrun Athena.  The Transaction Manager will be required to provide certain administrative, collection and other management services for Sunrun Athena and in respect of the managing members owned by Sunrun Athena.  
Events of Default and Amortization Events
 The Indenture contains events of default that are customary in nature for solar securitizations of this type, including (a) the non-payment of interest or principal, (b) material violations of covenants, (c) material breaches of representations and warranties and (d) certain bankruptcy events. An event of default will also occur with respect to the Class A Notes if they are not paid in full at their rated final maturity.  The Class A Notes are also subject to amortization events that are customary in nature for solar securitizations of this type, including (i) asset coverage ratios falling below certain levels, (ii) a debt service coverage ratio falling below certain levels and (iii) the failure to maintain insurance. The occurrence of an amortization event or an event of default could result in accelerated amortization of the Class A Notes, and the occurrence of an event of default could, in certain instances, result in the liquidation of the collateral securing the Class A Notes.
The description of the Indenture is qualified in its entirety by reference to the full text of the Indenture, a copy of which Sunrun plans to file as an exhibit to its Annual Report on Form 10-K for the year ending December 31, 2018.

Use of Proceeds
Sunrun intends to use the proceeds from the sale of the Class A Notes for repayment of borrowings under existing credit facilities, for the payment of fees and expenses related to the Transaction and to fund reserves required pursuant to the Transaction.
