ENDNOTES

¹ The $0.45 per share dividend is payable on October 16, 2017 to holders of record as of September 29, 2017.

² The discussion of the investment portfolio of both the Company and the SCF excludes the investment in a money market fund managed by an affiliate of The Goldman Sachs Group, Inc.

³ Computed based on the (a) annual stated interest rate or yield earned plus amortization of fees and discounts on the performing debt and other income producing investments, divided by (b) the total performing debt and other income producing investments (excluding investments on non-accrual) at amortized cost. The yield on the SCF has been computed based on the net investment income earned from the SCF for the trailing twelve months ended June 30, 2017, which may include dividend income and loan origination and structuring fees, divided by GS BDC’s average member’s equity at cost and fair value, adjusted for equity contributions.

⁴ The SCF’s return to the Company was measured at amortized cost over the trailing four quarters.

⁵ Total debt outstanding excluding netting of debt issuance costs of $4.2 million and $4.4 million, respectively, for the quarter ended June 30, 2017 and March 31, 2017.

⁶ The fixed versus floating composition has been calculated as a percentage of performing debt investments, including income producing stock investments.

⁷ For a particular portfolio company, EBITDA typically represents net income before net interest expense, income tax expense, depreciation and amortization. The net debt to EBITDA represents the ratio of a portfolio company’s total debt (net of cash) and excluding debt subordinated to the Company’s investment in a portfolio company, to a portfolio company’s EBITDA. The interest coverage ratio represents the ratio of a portfolio company’s EBITDA as a multiple of a portfolio company’s interest expense. Weighted average net debt to EBITDA is weighted based on the fair value of the Company’s debt investments, including the Company’s exposure to underlying debt investments in the SCF and excluding investments where net debt to EBITDA may not be the appropriate measure of credit risk, such as cash collateralized loans and investments that are underwritten and covenanted based on recurring revenue. Weighted average interest coverage is weighted based on the fair value of the Company’s performing debt investments, including the Company’s exposure to underlying debt investments in the SCF and excluding investments where EBITDA may not be the appropriate measure of credit risk, such as cash collateralized loans and investments that are underwritten and covenanted based on recurring revenue. Median EBITDA is based on the Company’s debt investments, including the Company’s exposure to underlying debt investments in the SCF and excluding investments where EBITDA may not be the appropriate measure of credit risk, such as cash collateralized loans and investments that are underwritten and covenanted based on recurring revenue. As of June 30, 2017, investments where EBITDA may not be the appropriate measure of credit risk represented 6.7% of total debt investments, including the Company’s investment in the SCF, at fair value. Portfolio company statistics are derived from the most recently available financial statements of each portfolio company as of the respective reported end date. Portfolio company statistics have not been independently verified by us and may reflect a normalized or adjusted amount.

⁸ Interest income excludes accelerated accretion/amortization of $3.4 million. Prepayment related income includes prepayment premiums and accelerated accretion of upfront loan origination fees and unamortized discounts.

⁹ The average debt to equity leverage ratio has been calculated using the average daily borrowings during the quarter divided by average net assets, adjusted for equity contributions. The ending and average debt to equity leverage ratio excludes unfunded commitments.
