3) further, securities falling in ‘DT’ and ‘T’ groups at present that do not satisfy any of the above exclusions are classified under “XT” sub-segment.

Clarification of X and XT group companies

As a part of Exchange's role towards ensuring market integrity, BSE is continuously looking for further strengthening of the market regulation framework particularly in respect of securities of companies that are only listed/traded at BSE, considering their specific characteristics such as large number of companies, low to moderate market capitalization, lower contribution to overall trading turnover and relatively higher attention required to be devoted to these securities by the Exchange, from a regulatory due diligence and monitoring standpoint.

It is therefore decided to classify equity securities of companies that are only listed/traded at BSE and satisfy certain parameters into separate sub-segments called "X", and "XT". At the time of review any securities falling in Trade-for-Trade segment ('DT' or 'T' groups) are classified under "XT" sub-segment.

Notice No. 20171124-33 for Merger of 'XC' and 'XD' Groups to 'X' Group
