(1)This table excludes any SBA-guaranteed debentures outstanding during the relevant periods because the SEC has granted the Company exemptive relief that permits it to exclude such debentures from the definition of senior securities in the asset coverage ratio the Company is required to maintain under the Investment Company Act.
(2)Total amount of each class of senior securities outstanding at the end of the period, presented in thousands.
(3)The asset coverage ratio for a class of senior securities representing indebtedness is calculated as the Company's consolidated total assets, less all liabilities and indebtedness not represented by senior securities, divided by total senior securities representing indebtedness. This asset coverage ratio is multiplied by $1,000 to determine the “Asset Coverage Per Unit.”
(4)The amount to which such class of senior security would be entitled upon the involuntary liquidation of the issuer in preference to any security junior to it. The “-” indicates information that the Securities and Exchange Commission expressly does not require to be disclosed for certain types of senior securities.
(5)Calculated on a daily average basis.
