Monthly Cash-Flow-Based Closed-End Fund Distributions

Each of the four taxable funds listed immediately below have adopted a cash-flow based distribution program. Potential distribution sources include net investment income, realized gains and return of capital. If a distribution includes anything other than net investment income, the fund provides a notice of the estimate of its distribution sources at the time of payment which may be viewed at: www.nuveen.com/CEFdistributions. These estimates may not match the final tax characterization contained in shareholders’ 1099-DIV forms after the end of the year.

Under a cash-flow based distribution approach, each fund seeks to maintain a stable regular distribution amount based on the fund’s net cash flow received from portfolio investments. Fund distributions are not intended to include expected portfolio appreciation; each fund may invest in securities which have cash flow that ultimately may be fully or partially treated as gains or return of capital for tax purposes. You should not draw any conclusions about a fund’s past or future investment performance from its current distribution rate.

The following dates apply to today's monthly cash-flow based distribution declarations and quarterly distributions for the following closed-end funds:

Quarterly Taxable Closed-End Fund Distributions

The goal of a fund’s managed distribution program is to provide shareholders relatively consistent and predictable cash flow by systematically converting its expected long-term return potential into regular distributions. As a result, potential distribution sources for regular distributions throughout the year include realized gains and return of capital, in addition to net investment income. If a distribution includes anything other than net investment income, the fund provides a notice of the best estimate of its distribution sources at that time which may be viewed at www.nuveen.com/CEFdistributions. These estimates may not match the final tax characterization (for the full year’s distributions) contained in shareholders’ 1099-DIV forms after the end of the year.

Under a Managed Distribution policy, each of the five funds listed immediately below seeks to maintain an attractive and stable regular distribution amount that, over the long term, matches the fund’s total distributions paid to its total return. You should not draw any conclusions about a fund’s past or future investment performance from its current distribution rate. Actual returns likely will differ from projected long-term returns (and therefore a fund’s distribution rate), at least over shorter time periods. Over a specific timeframe, the difference between actual returns and total distributions will be reflected in an increasing (returns exceed distributions) or a decreasing (distributions exceed returns) fund net asset value.

• A return of capital is a non-taxable distribution of a portion of the fund’s capital. When fund returns exceed distributions, return of capital may represent portfolio gains earned, but not realized as a taxable capital gain. In periods when fund returns fall short of distributions, it will represent a portion of your original principal unless the shortfall is offset during other time periods over the life of your investment (previous or subsequent) when the fund’s total return exceeds distributions.
