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.
2The fund paid short-term capital gains on October 7, 2016 in anticipation of converting to a floating net asset value (NAV) per share structure and calculating NAV using market-based pricing (in lieu of amortized cost) on October 11, 2016. Please note that the fund's shadow NAV decline on the ex-dividend date, October 7, 2016, reflects the $0.000049820 per share capital gain distribution.
