Valuation and NAV disclosure: require independent quarterly valuation and disclose the lower NAV when dual measures apply. Issuers of listed security receipts must obtain an independent valuation at each quarter end and the asset reconstruction company must declare NAV within fifteen days; issuers must also comply with Reserve Bank of India credit rating requirements and, in quarters where both external valuation and credit rating NAVs apply, disclose the lower of the two NAVs.
