I tend to think that they should be very careful while doing this. Most SME's out there are highly leveraged and have lots of cash flow problems due to this. This coupled with the owner being the only 'business development manager' it puts the viability of the company after the owner leaving at a high risk.
I think the parameters to be used have to extend out of the capital scope and they should check other issues too. You'll realize that some of these companies that are in the top 100 SME's are there by the virtue of mostly accessing government tenders this attaches a high political risk to most of them, i know of some companies that the owner still runs the company's bank account like his own personal account, have to sets of financial statements (for accessing loans and the real one)and his/her own personal and household items are shown as belonging to the company.
Guys who'll invest in this segment will have to be extremely careful though with a high risk appetite.

Chandaria's conglomerate is a family business so i highly doubt he'll be interested in putting it up to public scrutiny. we may have another AK debacle where the family run everything from sweeping the corridor to peddling their IT solutions
