Fund fees and expenses are presented as a percentage of both common shareholder capital and total fund investment capital. Total investment capital includes common assets as well as assets attributable to the fund's issuance of senior securities (e.g. preferred shares and debt). The table's first column portrays the costs directly and indirectly borne by common shareholders on an investment in the fund's common shares. The table's second column portrays the costs borne by the fund on its total investment capital, which enables a common shareholder to better understand how fund expenses impact portfolio investment returns. Interest expenses from leverage are shown separately, because they represent costs associated with the fund's financing activities which are distinct from the costs associated with the fund's underlying core operations.
