| (18) | Generation Brands Holdings, Inc. was previously incorrectly reported as a controlled investment in the financial statements for the year ended March 31, 2014. After further assessment, the Company does not control more than 25% of the voting power and has no power to direct or cause the direction of the policies and management of the company.

| (2) | The asset coverage ratio for the total senior securities representing indebtedness is calculated as our total assets, less all liabilities and indebtedness not represented by senior securities, divided by the total senior securities representing indebtedness. This asset coverage ratio is multiplied by one thousand to determine the Asset Coverage Per Unit. In order to determine the Asset Coverage Per Unit for each class of debt, the Asset Coverage Per Unit was allocated based on the amount of indebtedness outstanding at the end of the period for each class of debt. |

|     |                                                                                                                                                                |

| (4) | Not applicable, except for with respect to the 2042 Notes, the 2043 Notes, and the Convertible Notes, as other senior securities do not have sufficient trading for an average market value per unit to be determined. The average market value per unit for each of the 2042 Notes, the 2043 Notes, and the Convertible Notes is based on the closing daily prices of such notes and is expressed per $100 of indebtedness (including for the 2042 Notes and the 2043 Notes, which were issued in $25 increments). |

|     |                                                                                                   |
