mgt should clarify their rationale for such forced sale

Folks it is illegal to download PDF of any books. Use Amazon.in for buying, During discount sale mostly you should be getting for 50% or sometimes more discount. I've personally bought books at over 85% discount too.

Secondly, you may buy used books from Amazon.com (USA Site) if you know someone can bring them to India. I've bought books for less than $3 including shipping (free for Prime members) which otherwise cost thousands of rupees in India.

Thirdly the cost of ignorance is more than the cost of buying books, IMHO.

Microfinance risks have manifested themselves in different ways. In my opinion the major sector risks are different from what has been listed above. I will list down a few:

a) Political risk: Microfinance comes under the purview of state governments. Since most of the rural MFI loans are given to economically backward strata of the society and also since they form a major chunk of voting population any impact on them can lead to heavy clamping down by the state govt. The AP microfinance crisis clearly shows how badly state government regulations can impact the industry in a state.
b) Geographic risk: Any geographic calamity can have severe impact on an MFI. Example of this are available when the recent floods in Pakistan Punjab wiped out the MFI industry assets.
c) Multiple loans: This has been the biggest challenge operationally to the Microfinance industry. It has manifested itself time and again. The credit bureaus only cover MFIs (as per RBI regulation only two MFIs can lend to a person) but they do not cover loans from SHGs(Self help groups), HFCs(Housing Finance Companies), NBFCs and of course the local pawn broker. SHG loan books are almost the same size as MFIs. The recent RBI guideline of increasing the ticket size from Rs 30,000 to Rs. 60,000 greatly increases this risk significantly. Also MFIs lending from non operational revenue generating activities (consumer activities) are highly prone to this.
d) Religious: In certain communities interest on a loan is considered against the basic tenets. This risk manifested in the Mysore region where MFI loans were given to silk weavers.
e) Disease: Since a large amount of MFI loans are for animal husbandry purposes any disease outbreak could lead to wiping out of huge assets (think about mad cow disease, bird flu).

Along with these the standard risks of financial institutes are all present. In most of the cases these risks have combined together and resulted into huge losses to MFIs. The NPA of below .1% is a mirage since whenever any of these risks strike the NPAs have risen very sharply and have destroyed the entire MFI capital base.

Coming to the listed players which again I have gone into details:

Satin: Very high leverage. Preferential shares as part of tier 1 capital reduces interest coverage significantly. Not sure about management ethics. +ve ROAs are heading North every quarter. High exposure to animal husbandry.
Arman: Great management, conservative, focused on their work. Geographic and political risks.
SKS: Decent mgmt., lowest borrowing cost (lowest lending cost), wide geographic presence.

DIsclosure: Exited Satin recently. Looking to enter SKS.

Well, I bought a good chunk(8% of my portfolio) yesterday as I felt this was an opportunity to buy in a great compounding story at a discount. Business is still strong and growing. Agri will recover at the max next year. So no doubt on the business side.
Promoters still own 51% and they are not going anywhere for sure. So far they have not shown any characteristics where I will doubt their capability/intention which should create any doubt in our minds.

well, you are right to question the motivation of boarders to raise doubts about the management. Promoters selling a large holding at discount always raises questions. From business point of view things have slowed considerably. CSM remains insulated but one needs to remember that Agri comm crash will ultimately hurt new product developments and consecutive droughts are not helping either.

Disc: I sold it just in time before I saw it spiking during the last few minutes yesterday.
