     All returns are in U.S. dollars, include dividends and
    capital gains, and are not continuously compounded. We sort stocks in a
    region into five market cap and five Investment equity (Inv) groups at
    the end of each June. 
     
    The size breakpoints for a region are the 3rd, 7th, 13th, and 25th
    percentiles of the region's aggregate market capitalization. The Inv
    breakpoints for all stocks in a region are the 20th, 40th, 60th, and 80th
    percentiles of Inv for the big (top 90% of market cap) stocks of the
    region. 
     
    The developed portfolios use developed size breaks, but we use the Inv
    breakpoints for each region to allocate the region's stocks to the developed
    portfolios. 
    Similarly, the developed ex us portfolios use developed ex us size breaks and regional Inv breakpoints.
    The 25 value-weight size-Inv portfolios for a region are the
    intersections of the independent 5x5 size and Inv sorts.
