Distribution and Interest Rate Risk [Member]
Prospectus [Line Items]
Risk [Text Block]	Distribution and Interest Rate Risk. The Fund’s per-share distribution rate will be recalibrated every five years beginning in January 2030. While the Fund’s investment strategy is expected to significantly reduce the variability of the periodic recalibration, there is nonetheless a risk that the Fund may ultimately recalibrate its distribution rate to be higher or lower than expected as a result of fluctuations in market interest rates. For instance, the recalibrated distribution rate may be lower than currently estimated if interest rates decrease prior to a recalibration date. On the other hand, if market interest rates increase following a recalibration date, the value of the Fund’s distributions, as well as the market value of the Fund’s shares, will decrease. Similarly, if inflation is higher than expected, shareholders face the risk that the value of the Fund’s distributions will decrease relative to the cost of relevant goods and services.
