ENDNOTES

¹ The $0.45 per share dividend is payable on January 15, 2019 to holders of record as of December 31, 2018.

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

³ Total debt outstanding excluding netting of debt issuance costs of $5.6 million and $3.3 million, respectively, as of September 30, 2018 and June 30, 2018.

⁴ Computed based on the (a) annual actual interest rate or yield earned plus amortization of fees and discounts on the performing debt and other income producing investments as of the reporting date, divided by (b) the total performing debt and other income producing investments (excluding investments on non-accrual) at amortized cost or fair value, respectively.

⁵ The fixed versus floating composition has been calculated as a percentage of performing debt investments, including income producing stock investments and excludes investments, if any, placed on non-accrual.

⁶ For a particular portfolio company, we calculate the level of contractual indebtedness net of cash (“net debt”) owed by the portfolio company and compare that amount to measures of cash flow available to service the net debt. To calculate net debt, we include debt that is both senior and pari passu to the tranche of debt owned by us but exclude debt that is legally and contractually subordinated in ranking to the debt owned by us. We believe this calculation method assists in describing the risk of our portfolio investments, as it takes into consideration contractual rights of repayment of the tranche of debt owned by us relative to other senior and junior creditors of a portfolio company. We typically calculate cash flow available for debt service at a portfolio company by taking net income before net interest expense, income tax expense, depreciation and amortization (“EBITDA”) for the trailing twelve month period. Weighted average net debt to EBITDA is weighted based on the fair value of our debt investments, including our 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.

For a particular portfolio company, we also calculate the level of contractual interest expense owed by the portfolio company, and compare that amount to EBITDA (“interest coverage ratio”). We believe this calculation method assists in describing the risk of our portfolio investments, as it takes into consideration contractual interest obligations of the portfolio company. Weighted average interest coverage is weighted based on the fair value of our performing debt investments, including our exposure to underlying debt investments in the SCF and excluding investments where interest coverage 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 our debt investments, including our 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.

Portfolio company statistics are derived from the financial statements most recently provided to us of each portfolio company as of the reported end date. Statistics of the portfolio companies have not been independently verified by us and may reflect a normalized or adjusted amount. As of September 30, 2018 and June 30, 2018, investments where net debt to EBITDA may not be the appropriate measure of credit risk represented 15.5% and 10.5%, respectively, of total debt investments, including our investment in the SCF, at fair value. Portfolio company statistics are derived from the financial statements most recently available to us 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.

⁷ Computed based on the net investment income earned from the SCF for the trailing twelve months ended September 30, 2018, 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.

⁸ For a particular portfolio company of the SCF, we calculate the level of net debt owed by the portfolio company, and compare that amount to measures of cash flow available to service the net debt. To calculate net debt, we include debt that is both senior and pari passu to the tranche of debt owned by the SCF, but exclude debt that is legally and contractually subordinated in ranking to the debt owned by the Senior Credit Fund. We believe this calculation method assists in describing the risk of the SCF’s portfolio investments, as it takes into consideration contractual rights of repayment of the tranche of debt owned by the SCF relative to other senior and junior creditors of a portfolio company. We typically calculate cash flow available for debt service at a portfolio company by taking EBITDA for the trailing twelve month period. For a particular portfolio company of the SCF, we also calculate the interest coverage ratio. We believe this calculation method assists in describing the risk of the SCF’s portfolio investments, as it takes into consideration contractual interest obligations of the portfolio company. Median EBITDA is based on the SCF’s debt investments. Portfolio company statistics are derived from the financial statements most recently available to us of each portfolio company of the SCF as of the respective reported end date. Statistics of the SCF’s portfolio companies have not been independently verified by us and may reflect a normalized or adjusted amount.

⁹ Interest income excludes prepayment premiums, accelerated accretion of upfront loan origination fees and unamortized discounts. Prepayment related income includes prepayment premiums and accelerated accretion of upfront loan origination fees and unamortized discounts.

¹⁰ 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 ratios exclude unfunded commitments.
