The investment seeks to track the performance of the Bloomberg Barclays Global Aggregate Float Adjusted Composite Index that measures the investment return of investment-grade U.S. bonds and investment-grade non-U.S. dollar-denominated bonds. The advisor intends to obtain its exposure to the bonds held in the index by investing all, or substantially all, of its assets in two Vanguard bond index ETFs (underlying funds), rather than in individual securities held in the index. The index is designed to track the market capitalized weights of the global investment-grade bond market.
