* Note: Beginning in October 2016, Form N-MFP required prime and tax-exempt money market funds to identify 

themselves as institutional or retail funds; up to that date, Funds reported without making this distinction. Government 

and Treasury funds are not required to distinguish between retail and institutional. See Appendix 2, Key Definitions.
