If you would like to know more, that
Bogleheads page I linked to above had some good Investment Policy Statement examples.
Not exact matches
From the
Bogleheads» 3 - fund
page: «For example, one could use Total Stock Market ETF (VTI), Vanguard Total International Stock Index Fund (VXUS) for international, and Vanguard Total Bond Market ETF (BND).»
And I can recommend reading the
pages under
Bogleheads Retirement Spending Models.
I chose these ETFS because the
Boglehead's wiki's Lazy Portfolio
page recommended them, but also because I do not have the required cash to invest in fractional shares of their equivalent mutual funds.
