This Exchange Traded Fund (ETF) endeavors to replicate the performance of the S&P International Preferred Stock Index, which is made up of preferred shares from developed countries outside of the United States. At least 80% of the fund's holdings will consist of securities directly included in the index or those with highly similar characteristics. The remaining portion, up to 20% of its assets, can be placed in futures, options, and swap agreements, as well as cash, cash equivalents, or even securities not part of the underlying index, if BFA judges these to contribute to the fund's tracking accuracy.
