Question: I keep hearing about Morningstar's moat ratings. What is this and how does it work?

Answer: Here at Morningstar we often talk about moats, not because we enjoy storming castles, but because we believe a company's economic moat can be a great indicator of its long-term prospects.

For the uninitiated, a company's "economic moat"--a term coined by Warren Buffett--refers to the degree to which a company has sustainable competitive advantages within its industry. Essentially, an economic moat refers to how likely a company is to keep competitors at bay for an extended period.
