The Barclays Capital U.S. Aggregate Bond Index is an unmanaged index of investment-grade fixed-rate debt issues with maturities of at least one year. This unmanaged index does not reflect fees and expenses and is not available for direct investment.

The BofA Merrill Lynch US Dollar 3-Month LIBOR Constant Maturity Index tracks the performance of a synthetic asset paying Libor to a stated maturity. The index is based on the assumed purchase at par of a synthetic instrument having exactly its stated maturity and with a coupon equal to that day's fixing rate. That issue is assumed to be sold the following business day (priced at a yield equal to the current day fixing rate) and rolled into a new instrument.
