Shares of Spanish language television and radio broadcaster Entravision Communication (NYSE: EVC) dropped as much as 20% in early trading Thursday, and are still trading off 15.9% as of 10:45 a.m. EDT. The sell-off came in response to a Q4 and full-year 2017 earnings report released last night, which showed Entravision reporting "adjusted" losses of $0.05 per share for the fourth quarter -- versus the $0.02 pro forma loss that analysts had expected.And yet, when calculated according to GAAP accounting standards, Entravision actually earned a profit.
