  • Securing Across-the-Board Dismissals of Shareholder Litigation Arising from Nuclear Plant Retirement

Client: Edison International

Munger, Tolles & Olson represented Edison International and its directors and officers in obtaining dismissals, and defending the dismissals on appeal, of shareholder claims arising from the retirement of the San Onofre Nuclear Generating Station and a related $3.3 billion settlement approved by the California Public Utilities Commission (CPUC). In 2015, news about alleged settlement talks with CPUC officials led to the filing of a federal securities class action, derivative actions in state and federal court, and a class action in federal court asserting stock-drop claims under the Employee Retirement Income Security Act (ERISA). This securities litigation proceeded in three courts while the company negotiated a revised settlement in the CPUC regulatory proceeding.

The securities class action was dismissed with prejudice in 2018, with the district court explaining that it “cannot put on blinders to facts Plaintiff wishes it not to see” and that further amendment was inappropriate because Edison and its executives had “prevailed three times on their motions to dismiss the same claims.” In 2019, the U.S. Court of Appeals for the Ninth Circuit affirmed the dismissal of the securities class action.

In 2018, a different federal district court dismissed the ERISA stock-drop class action, which alleged that Edison’s executives breached their duty of prudence under ERISA by permitting investment in allegedly overvalued Edison stock. In 2021, a different panel of the U.S. Court of Appeals for the Ninth Circuit affirmed the dismissal, in the court’s first published opinion applying a new pleading standard for ERISA stock-drop actions.

As for the related derivative litigation, the federal action was dismissed by the district court in 2016, after which the plaintiffs elected not to amend, and the state action was voluntarily dismissed in 2017.

  • Defending Valid Termination of Merger in an Expedited Trial and Securing Termination Fee

Client: Rent-A-Center

Munger, Tolles & Olson represented Rent-A-Center, which operates about 2,500 rent-to-own consumer goods stores in the United States, in an expedited trial in the Delaware Court of Chancery challenging Rent-A-Center’s termination of a proposed merger. Rent-A-Center agreed to be acquired by a private-equity firm pursuant to a merger agreement that allowed either party to terminate the deal before closing in certain circumstances, including if neither party gave written notice of an election to extend the term. After Rent-A-Center exercised its termination right, the acquirer and its main financial backer filed a complaint and motion for a temporary restraining order on December 21, 2018, seeking declaratory relief and specific performance requiring Rent-A-Center to complete the go-private transaction.

Over the next 11 weeks, Munger Tolles guided Rent-A-Center through fact and expert discovery, trial and substantial post-trial briefing. On March 14, 2019, less than three months after the case was filed, the court issued an opinion holding that although the plaintiffs had been “blindsided,” Rent-A-Center’s termination of the merger was valid. The court rejected the plaintiffs’ various claims of breach of contract, breach of the implied covenant of good faith and fair dealing, estoppel and waiver as “after-the-face rationalizations” of “startling” behavior and denied all of the relief the plaintiffs sought.

After that ruling, the acquirer agreed to settle Rent-A-Center’s counterclaims to recover the $126.5 million “reverse termination fee” that Rent-A-Center was owed under the merger agreement. Although the Court of Chancery had called the amount of the fee “enormous,” Rent-A-Center nonetheless received $92.5 million in settlement of its counterclaims, while continuing its existence as a public company.
