| (g) | Asset Coverage Per $100,000: Asset coverage per $100,000 is calculated by subtracting the Fund’s liabilities and indebtedness not represented by senior securities from the Fund’s total assets, dividing the result by the aggregate amount of the Fund’s senior securities representing indebtedness then outstanding (if applicable), plus the aggregate of the involuntary liquidation preference of the outstanding preferred shares, if applicable, and multiplying the result by 100,000. For purpose of asset coverage above, senior securities consist of preferred shares or borrowings of a Fund and does not include derivative transactions and other investments that have the economic effect of leverage such as reverse repurchase agreements and tender option bonds. If the leverage effects of such investments were included, the asset coverage amounts presented would be lower. |
