"The search for the enduring economic moat is the holy grail of value investing. These modern-day protected business castles allow their owners to earn high returns on capital, the ultimate goal for any long-term investor. In Why Moats Matter, Heather Brilliant and Elizabeth Collins provide a wonderfully detailed map to help both small and large investors find these great companies."
--John W. Rogers Jr., founder, chairman, and chief investment officer, Ariel Investments

"Morningstar's Economic Moat framework is a useful complement to Michael Porter's five forces model, as it approaches the issue of franchise quality from an investor's perspective. Armed with Morningstar's moat framework, I've been able to make better assessments of companies' competitive positions, which is a critical element of my stock-picking process."
--Michael Luciano, investment analyst and U.K. pilot fund manager, Fidelity Worldwide Investment
