CSE authorities had reportedly informed its board on Friday that L B Jha & Co, the audit firm engaged in preparation of evaluation, has submitted a provisional valuation of the bourse at Rs 75 crore.
The valuation was crucial for separation of trading rights from ownership of the exchange.
The separation was part of the demutualisation process, to be completed by July 31.
Top sources in the audit firm today denied submitting any such report.
