1) Countries other than the United States are modeled with local regional data instead of pure domestic data for these assets.  CAN uses USA funds, while GER & UK use EUR funds.

3) The data is based on USA REITs, but a broad global REIT fund is also a reasonably close alternative if no US fund is available.
