Refer to next slide for components and discussion of core net investment income. Additional information on core net investment income and a reconciliation of core net investment income to its most directly comparable GAAP financial measure, net investment income, can also be found by accessing the earnings releases posted to the Company’s website at http://www.whitehorsefinance.com. (2) Computed as the annual stated rate of the subordinated notes, based on the subordinated notes outstanding as of the period, and dividends received over the last twelve-month period, based on average capital invested.

6 Quarterly Operating Highlights Note: Numbers may not foot due to rounding. (1) Total investment income includes investment income (e.g., interest and dividends) from investments in STRS JV. (2) Core net investment income is a non-GAAP financial measure. 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). The presentation of this additional information is not meant to be considered in isolation or as a substitute for financial results prepared in accordance with GAAP. Additional information on core net investment income and a reconciliation of core net investment income to its most directly comparable GAAP financial measure, net investment income, can be found by accessing the earnings releases posted to the Company’s website at http://www.whitehorsefinance.com.
