BUSINESS BRIEFING / THEME PARKS

Six Flags Inc. said its common stock and preferred income equity redeemable shares would be suspended from trading on the New York Stock Exchange before market opening April 20 after it failed to meet NYSE listing standards.

Six Flags, which operates Magic Mountain in Valencia and other theme parks, said the shares would trade over the counter upon delisting. The New York company said it might issue a “significant number” of common shares under a restructuring plan, a move that could make it eligible to trade on a national exchange.
