 taxation. Each Fund files income tax returns in U.S. federal and applicable state and local jurisdictions. A Fund’s federal income tax returns are generally subject to examination for a period of three fiscal years after being filed. State and local tax returns may be subject to examination for an additional period of time depending on the jurisdiction. Management has analyzed each Fund’s tax positions taken for all open tax years and has concluded that no provision for income tax is required in the Fund’s financial statements. 74 Differences between amounts for financial statement and federal income tax purposes are primarily due to timing differences in recognizing gains and losses on investment transactions. Temporary differences do not require reclassification. As of year end, permanent differences that resulted in reclassifications among the components of net assets relate primarily to nondeductible expenses and taxable market discount. Temporary and permanent differences have no impact on a Fund’s net assets. As of year end, the aggregate cost and the net unrealized appreciation/(depreciation) of all investments for federal income tax purposes were as follows:
