Portfolio characteristics are based on equivalent exposure, which measures how a portfolio's value would change due to price changes in an asset held either directly or, in the case of a derivative contract, indirectly. The market value of the holding may differ.

The list of portfolio holdings is as of the date shown and may not represent current or future portfolio composition. This information should not be construed as a recommendation to buy or sell any of the securities mentioned.
