Six-Month Historical NAV1

in USD

1The "Six-Month Historical NAV" graph above reflects the following: for the period prior to October 11, 2016, the fund's net asset value per share calculated based on market factors (during such periods, the fund priced its shares for transactional purposes at a stable $1.00 per share using the amortized cost method as permitted by SEC regulations); and for periods beginning October 11, 2016, the fund's last daily calculation of its net asset value per share based on market factors and used for transactional purposes (that is, its floating share price). As a result of Federal changes to the regulations governing money market funds, the fund transitioned from a stable $1.00 net asset value per share to a floating share price on October 11, 2016.
