Valuation of debentures for issue of debentures to nri

Hello Friends

For issue of shares to a non-resident, shares of the company should be valued as per Discounted Cash flow method (RBI guidelines).

If debentures (convettible/non-convertible) are issued to a non-resident, then how to value the debentures? Is there any valuation method should be adopted for valuing debentures?

Kindly suggest..

Thanks in advance
