The book is an easy read, and does not require detailed knowledge of accounting in order to get value out of it. For fundamental investors, I recommend this book, with the proviso that it only works with non-financial companies. Financial companies are more complex (they are all accruals — the cash flow statement is not very useful), and can’t easily be analyzed for earnings quality from looking at the financial statements alone.

Users of financial statements that want to think a little more broadly about accounting should buy this book. Note that the sticker price of this book is stiff, at roughly $1 per page. Accounting mavens, whether they like the ideas should buy the book so that they can understand the issues involved. Even if they never become the standards, the ideas are the exemplar for fair value, and represent the opposition view in accounting.
