Bitten by Warren Buffett and Charlie Munger bug, over the past decade, I became a value investor.
I have spent a substantial amount of my time during the past decade first studying about and then trying to analyze Berkshire Hathaway.

This book presents the thought framework I arrived at for analysis.
Hope is that will stand the test of time in that the principles of framework will also provide for extensibility.

Details:
Berkshire Hathaway is a remarkable business. 
This book captures my thoughts on how one should attempt to understand Berkshire Hathaway. 
This book intends on providing a thought framework for analysis that will stand the test of time in that the principles of framework will also allow for extensibility. 
This book is intentionally very short one as it contains synthesis of my thoughts over time on this company. 
This book does not provide any quantitive analysis of Berkshire Hathaway nor would you find a detail business by business description, analysis or quantitative summation. 
Instead it attempts to provide a higher level abstract framework for analysis.
