I have uploaded the spreadsheet for sundaram finance in valueinvestor india google group.
Please use link - http://groups.google.com/group/valueinvestorindia to download the file. Please also see the disclaimer, as I am not recommending this stock. The spreadsheet analysis (correct or wrong) is my personal analysis of the company.
You can find the sum of the part analysis of the company under the tab – sum of parts.
Please feel free to leave a comment if you find something wrong in the spreadsheet.
