QUANTUMONLINE.COM SECURITY DESCRIPTION:  SPDR Portfolio High Yield Bond ETF, formerly SPDR BofA Merrill Lynch Crossover Corp. Bond ETF is an exchange-traded index fund or Index ETF that is a separate investment portfolio of the SPDR Series Trust, an open-end management investment company. INVESTMENT OBJECTIVE: The SPDR Portfolio High Yield Bond ETF seeks to provide investment results that, before fees and expenses, correspond generally to the price and yield performance of the ICE BofAML US Diversified Crossover Corporate Index, formerly BofA Merrill Lynch US Diversified Crossover Corporate Index. INDEX DESCRIPTION: The ICE BofAML US Diversified Crossover Corporate Index is designed to measure the performance of US dollar denominated BBB and BB corporate debt publicly issued in the US domestic market. Crossover corporate debt generally means corporate debt rated at levels where the lower end of investment grade debt and the higher end of high yield debt meet. Qualifying securities must be rated BBB1 through BB3, inclusive. Qualifying corporate issuers must have a primary risk exposure to an FX G10 or Western European country, or a territory of the US or a Western European country. Individual securities of qualifying issuers must have a fixed coupon schedule and a minimum amount outstanding of $250 million. Original issue zero coupon bonds, 144A securities, both with and without registration rights, and pay-in-kind securities, including toggle notes, qualify for inclusion. Callable perpetual securities qualify provided they are at least one year from the first call date. Fixed-to-floating rate securities also qualify provided they are callable within the fixed rate period and are at least one year from the last call prior to the date the bond transitions from a fixed to a floating rate security. Eurodollar securities (USD securities not issued in the US domestic market), Tier 1 subordinated debt, taxable and tax-exempt US municipal, warrant-bearing, DRD-eligible and defaulted securities are excluded from the Index. Qualifying constituents are segmented into two groups: those rated between BBB1 and BBB3, inclusive, and those rated between BB1 and BB3, inclusive. Within the two groups, constituents are capitalization-weighted. Each group is then assigned a 50% weight in the overall index; with a 2% cap on each issuer. As of May 31, 2012, there were approximately 3,029 securities in the Index and the modified adjusted duration of securities in the Index was approximately 5.68 years. FUND STRATEGY: The Fund employs a sampling strategy, which means that the Fund is not required to purchase all of the securities represented in the Index. Instead, the Fund may purchase a subset of the securities in the Index in an effort to hold a portfolio of securities with generally the same risk and return characteristics of the Index. The quantity of holdings in the Fund will be based on a number of factors, including asset size of the Fund. Under normal market conditions, the Fund generally invests substantially all, but at least 80%, of its total assets in the securities comprising the Index or in securities that has been determined to have economic characteristics that are substantially identical to the economic characteristics of the securities that comprise the Index. In addition, the Fund may invest in debt securities that are not included in the Index, cash and cash equivalents or money market instruments, such as repurchase agreements and money market funds. FUND MANAGEMENT: SSgA FM serves as the investment adviser to the Fund.
