At September 30, 2017, there were no Level III portfolio investments for which significant unobservable inputs were used to determine fair value.

The Funds’ policy is to recognize transfers between valuation levels at the end of the reporting period.

At September 30, 2017, there were no significant transfers in or out of Level I and Level II fair value measurements.

The inputs or methodology used for valuing investments are not necessarily an indication of the risk associated with investing in those securities.
