1=Indicative

Index computed using alternate prices of the underlying constituents to provide an indicative index level.

2=Pre-Market

Pre-market index data for certain key   headline indices will be generated typically one hour prior to the actual start of trading day.

The pre-market index data will contain: Index values flat-lined with previous   day's index close levels. Index Bid & Ask values computed using real-time   pre-market quotes of the underlying constituents. The pre-market index ticks   should be considered as an initialization phase for the index before the   start of the trading day. The pre-market index ticks serve the purpose of a   system health check prior to the actual open of the index. All market data   vendors are encouraged to distribute the pre-market index ticks with an   appropriate pre-market indicator. The index values produced during pre-market   do not contribute to the Daily Open, High and Low. Additionally, the Index   Bid and Ask values computed using pre-market quotes provides an early   indication of the index spread before the start of trading day.

3=Preliminary Close

The index tick computed using real-time prices just before the official index close is published.

4=Session Close

The index level computed using the mid-day close prices of the underlying constituents.
