When assigning economic moat ratings, Morningstar analysts and the Morningstar economic moat committee take both quantitative and qualitative considerations into account.

Additionally, clear evidence must exist that the company benefits from at least one of five moat sources: intangible assets, cost advantage, switching costs, network effect, and efficient scale.
