For the third year in a row, Buchanan Ingersoll & Rooney has been recognized as a Go-To Law Firm by its Fortune 500 clients for delivering "exceptional work" to in-house counsel.

To compile the list, American Lawyer Media polls the legal departments of Fortune 500 companies to determine which law firms they call on to deliver outside counsel. Buchanan was also named by its clients in 2012 and 2011.

The full list of honored firms will be featured in the April editions of Corporate Counsel and The American Lawyer magazines.
