Interview Stephen Penman - Columbia Business School Accounting Prof, Author of ...

Stephen Penman is the George O. May Professor of Accounting at the Columbia Business School. He is the author of “ Financial Statement Analysis and Security Valuation “, for which he received a Wildman Medal Award. He also recently authored a book titled " Accounting for Value ." The book’s novel approach shows that valuation and accounting are much the same: Valuation is actually a matter of accounting for value. Stephen is also an editor of the Review of Accounting Studies. I grew up in Queensland, Australia and went to the University of Chicago for my Ph.d. studies. Then followed a wonderful 22 years at the Haas School at Berkeley, moving to Columbia in 1999. With exposure to those three great institutions, I feel truly blessed. The exposure to efficient market theory at Chicago and the Benjamin Graham fundamentalist tradition at Columbia has provided quite a contrast―and prompted some fresh thinking. Not directly. Of course Bruce Greenwald, Joel Greenblatt , Paul Sonkin and the folks there are good colleagues, but I am primarily involved with the Center for Excellence in Accounting and Security Analysis (CEASA). CEASA has similar interests to the Heilbrunn Center―equity investing―and very much take a fundamental approach, but our focus in on accounting: What sort of accounting does the fundamental investor need? And: How does the investor handle accounting in valuation? These are the themes in my new book, Accounting for Value . What does good accounting look like, and how does the value investor handle bad accounting? GAAP has both. This is a text book for business school classes on valuation, though I find it is increasingly being read by professionals seeking a deeper treatment of the subject. It is different from the usual “security analysis” text which deals with so-called “asset pricing” that runs students through the Capital asset Pricing Model (CAPM) and beta-bashing (as my students call it). Rather, the book takes as activist approach, seeing the primary risk not as beta but the risk of paying too much for a stock. It marries accounting and finance to address valuation issues. How do I do fundamental analysis? How do I understand value in a business and how do I employ the financial statements―the lens on the business―in doing so? Most importantly, how do I handle information to reduce the risk of paying too much?

[PATCH] bnx2x: suppress repeated error messages about Max BW ...

When a VN is configured with invalid Max BW, the error does not have to be logged repeatedly and fill the logs. Warn only once when the bad configuration is detected on boot, or when the configuration changes dynamically from good to bad.
