Financial professionals have long faced the challenge of accurately valuing companies that are difficult to value using conventional methodologies. Years ago, this challenge was most keenly felt in the "dot-com" industries, and many professionals fell victim to the "dark side," creating values that were simply unsustainable. Now, amidst today's global financial crisis, the same challenge applies to a far wider spectrum of enterprises and assets, ranging from Asian equities to mortgage-backed securities, financial services firms like Lehman to real estate firms like Sears. In The Dark Side of Valuation, the world's top expert on valuation brings together today's best practices for accurately valuing young, distressed, and complex businesses. Aswath Damodaran has thoroughly revised this book, broadening its perspective to consider all companies that resist easy valuation. He covers the entire corporate lifecycle, from "idea" and "nascent growth" companies to those in decline and distress; and offers specific guidance for valuing infrastructure, real estate, technology, human capital, commodity, and cyclical firms. Damodaran places special emphasis on the financial sector, illuminating the implications of today's radically changed credit markets for valuation. Along the way, he addresses valuation questions that have suddenly gained urgency, ranging from "Are US treasuries risk-free?" to "How do you value assets in highly illiquid markets?"
