Title 15 › CHAPTER 2B — SECURITIES EXCHANGES › § 78u–4
Private securities class actions must follow special rules about who can represent the class, how the case is started, and how settlements and fees are handled. Any person who wants to be a class representative must file a signed statement with the complaint saying they reviewed and approved the suit, did not buy the stock to join the suit or at a lawyer’s direction, are willing to represent the class and testify if needed, list all their trades in the security during the class period, name any time in the last 3 years they tried to be a class representative, and agree not to take more than their share of any recovery except court-approved costs. Within 20 days after the complaint is filed, the plaintiff must publish a national business notice telling class members about the suit and that they have 60 days to ask the court to be lead plaintiff. The court must pick a lead plaintiff within 90 days after that notice. The court will usually pick the person or group who filed or moved first, has the biggest financial stake, and meets class-rule requirements, unless someone proves they are not adequate or have unique defenses. The chosen lead plaintiff selects counsel (with court approval). One person may not serve as lead plaintiff, or as an officer, director, or fiduciary of a lead plaintiff, in more than 5 such cases in any 3-year period. Settlements are generally public unless the court finds a specific part would cause direct and substantial harm if published. Attorneys’ fees must be a reasonable percentage of the money actually paid to the class. Any notice about a settlement must say how much the class will get (total and per share), explain how damages were estimated or state disagreements about that, say who will ask for fees and how much (total and per share), give contact information for class counsel, and explain why the settlement is proposed. When a suit accuses someone of misleading statements or leaving out important facts, the complaint must say exactly which statements are at issue, why they are wrong, and give detailed facts if the claim is on information and belief. If the plaintiff needs to show the defendant’s state of mind, the complaint must give facts that create a strong inference of that state of mind (with a special rule for credit rating agencies). If these pleading rules are not met, a defendant can move to dismiss and discovery is paused while that motion is decided, unless the court allows particular discovery to save evidence or prevent unfair harm. The plaintiff must prove that the defendant’s act or omission caused the loss. Courts must check at the end of the case whether parties and lawyers followed court rules and can impose sanctions, usually making the wrong side pay the other side’s fees unless that would be unfair. Defendants can ask the jury in writing about each defendant’s state of mind. Damages based on market price are capped at the difference between the plaintiff’s purchase or sale price and the mean trading price during the 90-day period after the corrective information reaches the market (or the period until the plaintiff sells or repurchases, if earlier). Liability among defendants is usually split based on each one’s share of responsibility, except someone is jointly and severally liable only if the fact-finder finds they knowingly committed a securities law violation. If some defendants cannot pay, rules govern how the unpaid share is reallocated, with special protections for small individual plaintiffs (recoverable damages more than 10% of net worth and net worth under $200,000). A defendant who pays more than their share may seek contribution from others, and contribution claims must be brought within 6 months after the final judgment or, if extra payments were made under reallocation rules, within 6 months after that payment. “Knowingly” and “covered person” are defined in the law, and reckless conduct alone is not the same as knowing conduct.
