The U.S. Securities and Exchange Commission has created a guessing game for lawyers who work on all sides of corporate misconduct complaints.

Whistleblower lawyers, compliance officials and advocacy groups are waiting to see the details of how the SEC plans to award money to those who submit a “high-quality” tip about alleged corporate wrongdoing. The SEC issued draft rules in November and is expected to release revisions as soon as this month, though no one outside the agency can be sure exactly when after it missed an April deadline imposed by Congress.
