When BlackRock seeks to purchase or sell the same assets for client accounts, including the
Funds, the assets actually purchased or sold may be allocated among the accounts on a basis determined in its good faith discretion to be equitable. In some cases, this system may adversely affect the size or price of the assets purchased or sold
