If, in any taxable year, a Fund were to fail to meet the 90% gross income, diversification or distribution test described above, the Fund could in some cases cure such failure, including by paying a Fund-level tax, paying interest, making additional distributions, or disposing of certain assets. If a Fund were ineligible to or did not cure such a failure for any taxable year, or otherwise failed to qualify as a RIC accorded special tax treatment under the Code, the Fund would be subject to tax on its taxable income at corporate rates, and all distributions from earnings and profits, including distributions of net tax-exempt income and net long-term capital gain (if any), would be taxable to shareholders as dividend income. In such a case, distributions from the Fund would not be deductible by the Fund in computing its taxable income. In addition, in order to requalify for taxation as a RIC, the Fund may be required to recognize unrealized gains, pay substantial taxes and interest, and make certain distributions.
