1. As a supplement to U.S. generally accepted accounting principles (“GAAP”) financial measures, the Company has provided this non-GAAP financial measure. The Company believes that this non-GAAP financial measure is useful as it excludes the accrual of the capital gain incentive fee, including the portion of such accrual that is not contractually payable under the terms of the Company’s investment advisory agreement with GC Advisors (the “Investment Advisory Agreement”). In accordance with GAAP, the Company is required to include aggregate unrealized appreciation on investments in the calculation and accrue a capital gain incentive fee on a quarterly basis as if such unrealized capital appreciation were realized, even though such unrealized capital appreciation is not permitted to be considered in calculating the fee actually payable under the Investment Advisory Agreement. As of December 31, 2017, the cumulative capital gain incentive fee accrued by the Company in accordance with GAAP is $7.6 million, of which $1.2 million was payable as a capital gain incentive fee payable pursuant to the Investment Advisory Agreement as of December 31, 2017. The Company did not pay any capital gain incentive fees under the Investment Advisory Agreement for any period ended prior to December 31, 2017. Although this non-GAAP financial measure is intended to enhance investors’ understanding of the Company’s business and performance, this non-GAAP financial measure should not be considered an alternative to GAAP. Refer to slide 4 for a reconciliation to the nearest GAAP measure, net investment income per share. Summary of Quarterly Results 3 First Fiscal Quarter 2018 Highlights − Net increase in net assets resulting from operations (i.e. net income) for the quarter ended December 31, 2017 was $21.3 million, or $0.36 per share, as compared to $22.5 million, or $0.38 per share, for the quarter ended September 30, 2017. − Net investment income for the quarter ended December 31, 2017 was $18.5 million, or $0.31 per share, as compared to $18.3 million, or $0.31 per share, for the quarter ended September 30, 2017. Excluding a $0.7 million accrual for the capital gain incentive fee, net investment income for the quarter ended December 31, 2017 was $19.2 million, or $0.321 per share, as compared to $19.1 million, or $0.321 per share, excluding a $0.8 million accrual for the capital gain incentive fee for the prior quarter. − Net realized and unrealized gain on investments and secured borrowings of $2.8 million, or $0.05 per share, for the quarter ended December 31, 2017 was the result of $0.5 million of net realized gains and $2.3 million of net unrealized appreciation. This compares to a net realized and unrealized gain on investments and secured borrowings of $4.2 million, or $0.07 per share, for the prior quarter. − On December 28, 2017, we paid a quarterly distribution of $0.32 per share and a special distribution of $0.08 per share. Excluding the special distribution, our net asset value per share would have increased as of December 31, 2017 because our earnings per share of $0.36 exceeded our regular quarterly distribution of $0.32 per share. As a result of the special distribution, our net asset value per share declined to $16.04 as of December 31, 2017 from $16.08 as of September 30, 2017. − New middle-market investment commitments totaled $142.2 million for the quarter ended December 31, 2017. Approximately 27% of the new investment commitments were senior secured loans, 72% were one stop loans, and 1% were investments in equity securities. Overall, total investments in portfolio companies at fair value increased by approximately 2.3%, or $38.4 million, during the quarter ended December 31, 2017.

Weighted average interest rate on new investments is based on the contractual interest rate at the time of funding. For variable rate loans that have a LIBOR or Prime rate option, the contractual rate is calculated using current LIBOR at the time of funding, the spread over LIBOR and the impact of any LIBOR floor. For variable rate loans that only have a Prime rate option, the contractual rate is calculated using current Prime at the time of funding, the spread over Prime and the impact of any Prime floor. For fixed rate loans, the contract rate is the stated fixed rate. 2. Excludes activity on the subordinated note investment in SLF. On December 30, 2016, the subordinated notes previously issued by SLF were redeemed in full and terminated. 3. Excludes exits on investments on non-accrual status. 4. Investment income yield is calculated as (a) the actual amount earned on earning investments, including the subordinated note investment in SLF, including interest and fee income and amortization of capitalized fees and discounts, divided by (b) the daily average of total earning investments at fair value. On December 30, 2016, the subordinated notes previously issued by SLF were redeemed in full and terminated. 5. Income yield is calculated as (a) the actual amount earned on earning investments, including the subordinated note investment in SLF, including interest and fee income but excluding amortization of capitalized fees and discounts, divided by (b) the daily average of total earning investments at fair value. On December 30, 2016, the subordinated notes previously issued by SLF were redeemed in full and terminated. 6. The weighted average cost of debt is calculated as (a) the actual amount incurred on debt obligations divided by (b) the daily average of total debt obligations. 7. The weighted average net investment spread is calculated as (a) the investment income yield less (b) the weighted average cost of debt.

As a supplement to GAAP financial measures, the Company has provided this non-GAAP financial measure.

The Company’s annualized return on investments in SLF is calculated by dividing total income (loss) earned on the Company’s investments in SLF by the combined daily average of its investments in (1) the principal of the outstanding SLF subordinated notes, if any, and (2) the net asset value of the SLF LLC equity interests. Annualized total return excludes the impact of management fees and incentive fees that may be charged by GC Advisors based on the Company’s investments in SLF and the income from such investments.
