Despite its somewhat high fee level, Morningstar assigned a five-star overall rating and a silver analyst rating for the fund's combination of experienced management, thorough analysis and superior returns.

The fund hedges its currency risk and keeps its foreign currency exposure to no more than 20% of its total assets.
