Nuveen Variable Rate Preferred & Income Fund

*The ratio of total assets of the Fund, less all liabilities that are not outstanding borrowings or outstanding preferreds, at par, to the sum of the Fund’s outstanding borrowings and outstanding preferreds, at par.

**The annualized ratio of the sum of leverage costs to the average leverage amount for a given time period.

Fund fees and expenses are presented as a percentage of both common shareholder capital and total fund investment capital. The first column portrays the costs directly and indirectly borne by common shareholders. The second column portrays the costs borne by the Fund on its total investment capital, which includes common assets as well as assets attributable to the Fund's issuance of senior securities (e.g. preferred shares and debt). This column enables a common shareholder to better understand how fund expenses impact portfolio investment returns. Interest expenses from leverage represent costs associated with the Fund's financing activities, which are distinct from the costs associated with the Fund's underlying core operations. Certain leveraging instruments including repurchase agreements (repos) are sometimes more efficient forms of leverage, but when used, the costs are difficult to accurately disaggregate and are not shown here.

Expense ratios are calculated using the prior 12 months of expense data as of the previous month-end, except for new funds where the prospectus expense ratios are used for the first full three months following the Fund’s inception.  After the initial three months, actual expenses, annualized, are used until a full 12 months of expenses have been recorded. Annualized leverage financing expense is included if the Fund was leveraged as of the previous month end.
