[1] The S&P 500 Index is an unmanaged capitalization-weighted index of 500 stocks designed to measure performance of the broad domestic economy through changes in the aggregate market value of 500 stocks representing all major industries.
[2] The 60% Bloomberg US Aggregate Bond / 40% Russell 1000 Value is a custom blended index comprised of 60% of the return of the Bloomberg US Aggregate Bond Index and 40% of the return of the Russell 1000 Value Index. The Russell 1000® Value Index measures the performance of the large-cap value segment of the U.S. equity universe. It includes those Russell 1000® Index companies with lower price-to-book ratios and lower expected growth values. The Russell 1000® Value Index is constructed to provide a comprehensive and unbiased barometer for the large-cap value segment. The Russell 1000® Value Index is completely reconstituted annually to ensure new and growing equities are included and that the represented companies continue to reflect value characteristics. The Bloomberg US Aggregate Bond Index is a broad-based benchmark that measures the investment-grade, U.S. dollar-denominated, fixed-rate, taxable bond market, including Treasuries, government-related and corporate securities, mortgage-backed securities (agency fixed-rate and hybrid ARM pass-throughs), asset-backed securities and commercial mortgage-backed securities.
