Effective Monday, April 23, 2001, the timing of when the lead month 2.5% upside price limit is lifted on stock index futures contracts will change from the current 8:30 a.m. to 8:28 a.m. CST. This will affect the E-mini S&P 500, E-mini Nasdaq-100, S&P 500/BARRA Growth & Value and FORTUNE e-50 futures contracts.

The reasoning behind this change is that the additional two minutes will enable traders to get their electronic orders in line with where the open outcry market will open.
