|SPDR S&P Mortgage Finance ETF|
|The investment seeks to provide investment results that, before fees and expenses, correspond generally to the total return performance of an index derived from the mortgage banking, processing and marketing segment of the U.S. financial services industry.
In seeking to track the performance of the S&P Mortgage Finance Select Industry Index (the "index"), the fund employs a sampling strategy. It generally invests substantially all, but at least 80%, of its total assets in the securities comprising the index. The index represents the mortgage finance industry group of the S&P Total Market Index ("S&P TMI"). The fund is non-diversified.|
