[1] Total amount of each class of senior securities outstanding at the end of the period presented.

[2] The asset coverage ratio for a class of senior securities representing indebtedness is calculated as our total assets, less all liabilities and indebtedness not represented by senior securities, divided by senior securities representing indebtedness. The asset coverage ratio with respect to indebtedness is multiplied by $1,000 to determine the Asset Coverage Per Unit.

[3] The amount to which such class of senior security would be entitled upon the voluntary liquidation of the issuer in preference to any security junior to it. The “—” in this column indicates that the SEC expressly does not require this information to be disclosed for certain types of senior securities.
