`` The Chicago Board Options Exchange will pay a $6 million penalty and take "major remedial measures" to settle civil charges that it failed to properly enforce short sale rules, U.S. regulators said on Tuesday. The financial penalties against the exchange operator and C2 Options Exchange, an affiliate, are the first ever against a U.S. exchange for violating the duty to self-police a marketplace, the U.S. Securities and Exchange Commission said.''
