United Continental Holdings Inc. expects a non-cash charge of $105 million in the second quarter in connection with its Brazil routes, the airline said late Friday in a filing. Brazil and the U.S. ratified in May an open-skies agreement, which "removes all limitations or reciprocity requirements for flights between the United States and Brazil. Accordingly, the company expects to record this special charge to write off the entire value of the intangible asset associated with its Brazil routes," United Continental said in the filing. The asset is not part of any collateral pledged against any of the company's borrowings, the company added. Shares of United Continental were flat in late trading Friday after ending the regular trading day up 0.1% at $70.96.
