Item 1.01. Entry into a Material Definitive Agreement.

On January 31, 2018 (the “Closing Date”), Oaktree Strategic Income Corporation (the “Company”) entered into an Amended and Restated Loan and Security Agreement (the “Loan Agreement”) with OCSI Senior Funding II LLC (formerly FS Senior Funding II LLC), the Company’s wholly-owned, special purpose financing subsidiary, as the borrower, the lenders from time to time party thereto, Citibank, N.A., as administrative agent, and Wells Fargo Bank, National Association, as collateral agent (the “Restated Citibank Facility”).

The Restated Citibank Facility permits up to $100 million of borrowings. Borrowings under the Restated Citibank Facility are subject to certain customary advance rates and accrue interest at a rate equal to the London Interbank Offered Rate (“LIBOR”) plus 1.70% per annum on broadly syndicated loans and LIBOR plus 2.25% per annum on all other eligible loans during the reinvestment period. Following termination of the reinvestment period, borrowings under the Restated Citibank Facility accrue interest at rates equal to LIBOR plus 3.50% per annum and LIBOR plus 4.00% per annum during the subsequent two years, respectively. In addition, for the duration of the reinvestment period there is a non-usage fee payable of 0.50% per annum on the undrawn amount under the Restated Citibank Facility. The non-usage fee is increased pursuant to a formula if, after the ramp up period, the advances outstanding on the Restated Citibank Facility do not exceed 70% of the aggregate commitments by lenders.

The reinvestment period under the Restated Citibank Facility ends January 30, 2021, and the final maturity date is January 31, 2023. The Restated Citibank Facility requires the Company to comply with certain affirmative and negative covenants and other customary requirements for similar credit facilities.

The foregoing description of the Restated Citibank Facility is qualified in its entirety by reference to the complete text of the Loan Agreement, a copy of which is attached as Exhibit 10.1 to this Current Report on Form 8-K and is incorporated herein by reference.

The information provided in Item 1.01 of this current report on Form 8-K is incorporated by reference into this Item 2.03.
