Hello Harshil,

Thanks for your question. We have been addressing this very question inside of CFA Institute. Please see this The Enterprising Investor blog post - http://blogs.stage.cfainstitute.org/investor/2012/06/11/negative-nomina… - for a discussion about negative yields. Additionally, on the social media site LinkedIn there has been a detailed and rich discussion of these issues in the CFA Institute discussion group. So I would start in these two places for a good discussion.

With smiles!

Jason A. Voss, CFA
