SPDR SERIES TRUST PORTFOLIO SHORT TERM TREASURY ETF

The SPDR® Bloomberg Barclays Short Term Treasury ETF seeks to provide investment results that, before fees and expenses, correspond generally to the price and yield performance of the Bloomberg Barclays 1-5 Year U.S. Treasury Index. The Bloomberg Barclays 1-5 Year U.S. Treasury Index includes all publicly issued, U.S. Treasury securities that have a remaining maturity of greater than or equal to 1 year and less than 5 years, are rated investment grade, and have $250 million or more of outstanding face value. In addition, the securities must be denominated in U.S. dollars and must be fixed rate and non-convertible. Excluded from the Index are certain special issues, such as flower bonds, targeted investor notes, state and local government series bonds, inflation protected public obligations of the U.S. Treasury, commonly known as TIPS, and coupon issues that have been stripped from bonds included in the Index. Also excluded from the Index are structured notes with embedded swaps or other special features, private placements, floating rate securities and Eurobonds. The Index is market capitalization weighted and the securities in the Index are updated on the last business day of each month.
