S. companies. It began trading on that index on Tuesday.

While there is a bad news also for the Buffet owned company as Fitch Ratings cut its key rating of Berkshire Hathaway Inc. two notches within investment grade territory.

Fitch downgraded Berkshire Hathaway's issuer default rating two notches to AA-from AA+ but kept the rating at a level signifying very high credit quality.
