(each, a “Fund” and collectively, the “Funds”)

At a meeting on May 24, 2012, the Board of Trustees for the Funds approved a change in the minimum credit rating for the Funds’ swap counterparties.  The following sentence replaces the sentence regarding the credit rating of swap counterparties in, or, if not disclosed, is added to, the section entitled, “Investment Strategies and Risks – Interest Rate and Index Swaps,” “Investment Strategies and Risks – Swaps, Caps, Floors, and Collars,” “Investment Strategies and Risks – Interest Rate, Index, and Inflation Swaps,” or “Investment Strategies and Risks – Credit Default Swaps.”

Interest Rate and Index Swaps

The Fund[s] will not be permitted to enter into any swap transaction unless, at the time of entering into such transaction, the unsecured long-term debt of the actual counterparty, combined with any credit enhancements, is rated at least BBB- by S&P or Baa3 by Moody's or is determined to be of equivalent credit quality by the Manager.
