The OCSI Glick JV consolidated financial statements for the fiscal years ended September 30, 2019, 2018 and 2017 (Exhibit 99.1) are included in Part IV, Item 15 of this filing.
 
 We have determined that this unconsolidated controlled portfolio company has met the conditions of a significant subsidiary under Rule 1-02(w) of Regulation S-X for which we are required, pursuant to Rule 3-09 of Regulation S-X, to provide audited financial statements as an exhibit to the Form 10-K. In accordance with Rule 3-09(b), the separate financial statements of OCSI Glick JV are being filed as an amendment to the Form 10-K within 90 days after the end of OCSI Glick JV’s September 30 fiscal year.

 No other changes have been made to the Form 10-K. This Amendment does not reflect subsequent events that may have occurred after the original filing date of the Form 10-K or modify or update in any way disclosures made in the Form 10-K. Among other things, forward-looking statements made in the Form 10-K have not been revised to reflect events that occurred or facts that became known to us after filing of the Form 10-K, and such forward-looking statements should be read in their historical context.
