I just finished reading the book "There's Always Something to Do" which is an excellent story of Peter Cundill a net-net value investor. I'm not going to review the book because there are some excellent reviews on the internet already like the one Richard Beddard did here.
What I found fascinating is that Peter created a net-net template in the 1970s and continued to use it until he retired in 2009. The book doesn't discuss his template much but they do include a sample of one as an appendix. I took the liberty of creating what I consider a Peter Cundill inspired net-net template in Excel. I used a lot of things in his template but made a few modifications as well.
I have my own template that I've been using on this blog for a while that I might consider some modifications to after examining the one Peter used. When I research a stock I have an Excel spreadsheet that has different worksheets for income statement, balance sheet, cash flow, net-net worksheet. What I like about the Cundill template is that all of that information is on one worksheet which makes it easy to glance back and forth at different aspects of financial statements.
I am posting a link to the template as a free download for anyone interested. The file was uploaded to Google Docs, you can view it from there, and if you want a copy on your own PC select File->Download as.
Here is the link to the net-net template file
