FINANCIAL RESULTS EARNINGS OVERVIEW Earned net investment income of $0.21 per share for the third quarter of 2019, which was lower than prior quarter due to: Lower interest income primarily driven by a lower interest-bearing portfolio and a decrease in LIBOR; this was offset by Lower interest expense also driven by lower average debt outstanding and a lower LIBOR; as well as Reduced expenses due to not earning an incentive fee and lower general and administrative expenses during the quarter Net realized and unrealized losses on investments totaled $19.9 million, or $1.24 per share, for the third quarter 2019 due to: $18.9 million of negative credit-related adjustments from our investments in GIG Co Holdings, LLC (fka Confluence Outdoor, LLC), Gold Coast Bakeries, LLC, HRI Holding Corp. and four syndicated investments; and A net $1.0 million of negative market-related fair value adjustments across the remaining portfolio Declared a Q4 2019 dividend of $0.15 per share payable on December 20, 2019 to shareholders of record as of December 6, 2019 QUARTERLY EARNINGS ($ in thousands, except per share data) Q3 2019   Q2 2019   Q1 2019   Q4 2018   Q3 2018 Total investment income $ 9,713   $ 10,704   $ 10,229   $ 9,561   $ 9,312 Total expenses 6,290   7,230   6,982   6,401   5,578 Net investment income 3,423   3,474   3,247   3,160   3,734 Net realized gain/(loss) on investments 151   (2,365)   (7,133)   13   (27) Net change in unrealized (loss)/gain on investments (20,040)   284   6,296   (8,886)   (2,220) Loss on refinancing of debt - - - (2,218) - Net (decrease)/increase in net assets resulting from operations (16,466)   1,393   2,410   (7,931)   1,487                   Net investment income per share 0.21   0.22   0.20   0.20   0.23 Net realized/unrealized losses from investments per share (1.24)   (0.13)   (0.05)   (0.56)   (0.14) Loss on refinancing of debt per share -   -   -   (0.14)   - Net (losses)/earnings per share (1.03)   0.09   0.15   (0.50)   0.09 Dividends declared per common share 0.23   0.23   0.23   0.23   0.28 Net asset value per share 9.04   10.30   10.44   10.52   11.25
