URTH holds a comprehensive portfolio of large- and midcap stocks from developed countries. Covering 85% of the market capitalization, the fund captures the developed world well: It allocates more heavily towards US companies, with the remainder scattered among European and Asian countries, but these allocations are likely to change over time. Its portfolio provides highly diversified exposure to the developed markets. Overall, if you want to combine your domestic and international equity exposure into one fund and want to avoid emerging markets risk, URTH may be an option for you. The index is rebalanced quarterly.
