In a clarification to the BSE yesterday, Rolta India said, "This undated Glaucus Research Report is completely baseless and has factual errors and inconsistencies.
"The Glaucus Research Group has never contacted Rolta to verify any facts. This report is malafide, malicious and aimed at misleading investors with an ulterior motive - so that Glaucus Research Group can benefit from its short interest in Rolta's bonds."
The company is exploring all avenues including legal remedies to protect its interests, the filing had said.
