Five years ago, we wrote in our "Link of the Day," "Internal and Private Money Funds Revealed; TDAM Changes to TD; TRP," which reviewed the addition of a number of money market funds to Crane Data's collections. Our Jan. 5, 2017 piece said, "Since the SEC began publicly disclosing its Form N-MFP filings without a 2-month delay in April 2016, Crane Data has been parsing and integrating this new trove of data into our existing collections and products. Beginning with the January 2017 issue of our Money Fund Intelligence newsletter and MFI XLS performance spreadsheet (which will ship on 1/9), we will add a number of private and internal money market funds previously unreported to our listings. We've been offering these full fund listings in "beta" format in our "fundsnmfp" file (available to Money Fund Wisdom subscribers via our "Content" center) for a number of months now, and we've listed several of these in our Money Fund Portfolio Holdings collections for awhile, but watch for more inclusion in the coming months. We review the largest of these and our latest fund additions below.... The largest of these internal and private money funds include: Vanguard Market Liquidity Fund ($49.6 billion), Fidelity Cash Central Fund ($34.6B), DFA Short Term Investment Fund ($26.4B), Fidelity Securities Lending Cash Central Fund ($20.4B), Franklin U.S. Government MMP ($18.3B), Prudential Institutional MMF ($13.9B), Columbia Short-Term Cash Fund ($11.3B), State Street Navigator Securities Lending Govt MMP ($11.0B), TIAA-CREF Money Market Account ($11.1B), MFS Institutional Money Market Portfolio ($5.5B), JNL Money Market Fund ($3.8B), T. Rowe Price Treasury Reserve Fund ($3.2B), Vanguard Municipal Cash Management Fund ($2.4B), Fidelity Municipal Cash Central Fund ($2.1B), and Fidelity Money Market Central Fund ($1.8B). (Note that most of these do not have ticker symbols and many don't include the advisor name in their official filing names.) The 15 funds above total $219.7 billion, while the 10 Prime funds among these total $178.3 billion. We'll be adding approximately just over half of the assets this month ($110.3 billion), with most of the remainder added over the first half of 2017. (So be wary of these asset distortions in the coming months.) Note that these funds, and those listed in our Form N-MFP files (and on the SEC's site) are all true "money market mutual funds" -- if they report as money funds, they're money funds -- but most aren't available to outside investors. These additions don't, however, include private or internal "pools" that aren't registered as MMFs. (We're still slowly attempting to locate and identify many of these too. Contact us if you'd like to see our latest "fundsnmfp" list.) For more information on internal and private money funds and other pools, see our June 29, 2016 News, "UBS Liquidates Sweeps, Goes Govt; Vanguard Floats Internal Money Fund," our April 4, 2016 News, "Prudential Core MMF Goes Bond; BlackRock, BofA Approved; Calamos," and our July 10, 2015 News, "OFR Sheds Light on Liquidity Funds, STIFs, Managed Accts in Form PF."
