Yield & Interest Rate Economic Analysis 12 (1) Weighted average effective yield is computed by dividing (a) annualized interest income (including interest income resulting from the amortization of fees and discounts) by (b) the weighted average cost of investments. (2) Income yield is calculated as (a) the actual amount earned on earning investments, including interest and recurring fee income but excluding amortization of capitalized fees and discounts. (3) Calculated as (a) effective yield less (b) weighted average cost of debt. (4) The weighted average cost of debt is calculated as (a) the actual amount of expenses incurred on debt obligations divided by (b) the daily average of total debt obligations. (5) The base reference rate represents the weighted average base rate for the quarter applied on the JPM Revolving Credit Facility borrowings. 9.9% 9.6% 9.9% 9.9% 9.6% 9.5% 9.3% 9.1% 9.2% 9.9% 11.4% 12.6% 13.2% 13.4% 13.6% 13.7% 9.5% 9.1% 9.4% 9.4% 9.1% 9.0% 8.8% 8.6% 8.8% 9.4% 10.8% 12.1% 12.6% 12.9% 13.1% 13.2% 5.2% 5.4% 6.2% 6.1% 5.7% 5.7% 5.7% 5.7% 5.7% 5.9% 6.8% 7.1% 7.1% 7.1% 7.1% 7.2% 4.7% 4.2% 3.7% 3.8% 3.8% 3.8% 3.6% 3.4% 3.5% 4.0% 4.6% 5.5% 6.1% 6.3% 6.5% 6.5% 1.7% 1.0% 0.3% 0.2% 0.2% 0.2% 0.1% 0.2% 0.3% 0.9% 2.1% 3.7% 4.8% 5.0% 5.3% 5.4% 0.0% 2.0% 4.0% 6.0% 8.0% 10.0% 12.0% 14.0% 16.0% Q1'20 Q2'20 Q3'20 Q4'20 Q1'21 Q2'21 Q3'21 Q4'21 Q1'22 Q2'22 Q3'22 Q4'22 Q1'23 Q2'23 Q3'23 Q4'23 Effective Yield⁽¹⁾ Income Yield⁽²⁾ Net Investment Spread⁽³⁾ Weighted Average Cost of Debt⁽⁴⁾ Base reference rate⁽⁵⁾

The Company believes that core net investment income provides useful information to investors and management because it reflects the Company's financial performance excluding (i) the net impact of costs associated with the refinancing of the Company's indebtedness, (ii) the accrual of the capital gains incentive fee attributable to realized and unrealized gains and losses, and (iii) certain excise or other income taxes (net of incentive fees).
