The table below includes the number of holdings for each ETF and the percentage of assets that the top ten assets make up, if applicable. The interest rate on a Treasury FRN, which resets weekly, is the sum of 2 components: the index rate, which is tied to the rate of a recently auctioned 13-week Treasury bill, and the spread, which is set when the FRN is first auctioned and remains fixed for the life of the FRN. All other average annual and cumulative total returns shown are blended returns of the historical performance of Institutional Plus Shares and the fund's Institutional Shares. The performance data shown represent past performance, which is not a guarantee of future results.

The payable date also refers to the date on which a declared stock dividend or bond interest payment is scheduled to be paid. For each year, there is an ETF that invests in a broad range of corporate bonds and an ETF that invests only in bonds from non-financial corporations.
