Early and Often: DOJ Tells Companies to Cooperate Early or Pay the Price


An important issue for companies and their executives that are the subject of an investigation by the federal government is whether, and how early, to cooperate.

On September 27, 2016, Principal Deputy Associate Attorney General Bill Baer delivered remarks at the Society of Corporate Compliance and Ethics Conference, where he laid out in some detail his views on the value of early cooperation with the federal government in financial cases, and the consequences for waiting. As the number 3 attorney in the Department of Justice who is charged with overseeing civil litigation, antitrust, and other large divisions, Baer’s words are significant, and are a further gloss on the so-called “Yates Memo”, which Deputy Attorney General Sally Yates released last September, detailing DOJ’s guidance on individual accountability for corporate wrongdoing.

Speaking specifically about cases against banks and the fallout from protracted litigation involving residential mortgage-backed securities, Baer said those cases could have been resolved more quickly if only the financial institutions “had decided early to cooperate.” Consequently, “each [institution] paid a lot more than it would have if it had cooperated early on.” Recalling that many of these same institutions had nonetheless sought “significant cooperation credit,” Baer stated that DOJ “dismissed the arguments quickly because they so lacked merit.”

So how early is early enough, and how can your company get credit for cooperating? Baer elaborated on recent “internal” guidance he has provided to his attorneys in civil enforcement matters.


In a Case of First Impression, Delaware Chancery Court Holds It’s “Out with the Old (Board) and In With the New” When Considering Demand Futility

Chairs Around a Table

On May 31, 2016, the Delaware Chancery Court rejected shareholders’ allegations of corporate wrongdoing in a derivative suit against a national healthcare company, Bioscrip, holding that Plaintiff failed to adequately allege demand futility with respect to Bioscrip’s board of directors. For the first time, the Delaware Court found that Plaintiff was required to demonstrate demand futility with respect to the board of directors that was in place after shareholders filed their derivative complaint. Park Emps.’ & Ret. Bd. Emps.’ Annuity & Ben. Fund v. Smith, No. 11000-VCG (Ch. May 31, 2016).


Chancery Court Continues to Close the Door on Disclosure-Only Settlements and Fees (But Opens a Window for “Mootness Dismissals”)


As previously discussed here, in 2015, the Delaware Court of Chancery issued a number of decisions calling for enhanced scrutiny of “disclosure-only” M&A settlements that involve no monetary benefits to a shareholder class.  For example, the recent decision in In re Riverbed Technology, Inc. Stockholders Litigation expressly eliminated the “reasonable expectation” that a merger case can be settled by exchanging insignificant supplemental disclosures (and nothing more) for a broad release of claims.  In In re Trulia, Inc. Stockholder Litigation, the Chancery Court demonstrated that its “increase[ed] vigilance” in this area is genuine, rejecting a disclosure-only M&A settlement and finding that the supplemental disclosures did not warrant the broad release of claims.


SEC Eliminates References to Credit Ratings in Money Market Fund Rules


On September 16, 2015, the Securities and Exchange Commission (“SEC”) adopted revisions to Rule 2a-7, the primary rule governing money market funds.  The amendments implement provisions of the Dodd-Frank Act that require federal agencies to replace references to credit ratings in regulations with alternative standards of credit-worthiness, and are consistent with the SEC’s goal of reducing its reliance on credit ratings.


An Exercise of Business Judgment: Chancery Court Dismisses Shareholder Derivative Demand-Refused Case

Gavel and Hundred-Dollar Bill

Last week, Vice Chancellor Glasscock released an important decision dismissing a case under Rule 23.1 that was brought by a DuPont shareholder who alleged that the board improperly refused a demand to sue DuPont’s officers and directors.  The suing shareholder alleged that the individual defendants caused DuPont to incur sanctions in, and eventually lose, a patent-infringement case brought by Monsanto concerning DuPont’s unauthorized use of Monsanto’s patents.

The Delaware court held that the plaintiff had not adequately alleged that DuPont’s board of directors had been unreasonable or acted in bad faith in rejecting a demand to sue the directors and officers who were purportedly responsible for DuPont’s liability in the Monsanto patent litigation.


Highlights From SEC Speaks 2015


Securities and Exchange Commission leadership and staff members addressed the public on February 20-21 at the annual “SEC Speaks” conference in Washington, D.C.  Common themes among the numerous presentations included the Commission’s increasing use of data analytics, the Commission’s focus on gatekeepers such as accountants and attorneys, and the Commission’s still incomplete rulemakings mandated by both the Dodd-Frank Wall Street Reform and Consumer Protection Act and the Jumpstart Our Business Startups Act.


New House Bill Aims to Reduce Some Dodd-Frank Regulatory Burdens


On January 14, 2015, the U.S. House of Representatives passed a bill that loosens certain Dodd-Frank requirements and reduces the scope of the SEC’s regulatory authority over certain private equity firms, small businesses, and emerging companies. The bill is part of a larger fight between Democrats and Republicans over the scope of Dodd-Frank and government oversight over financial institutions generally.


For Now, The Broad Interpretation of “Foreign Officials” Under the FCPA Is Here to Stay

Blue Globe

In recent years, the DOJ and SEC have significantly increased their Foreign Corrupt Practices Act (FCPA) enforcement efforts, and in the process, have successfully advocated the theory that state-owned or state-controlled entities should qualify as instrumentalities of a foreign government under the FCPA. The FCPA defines a foreign official as “any officer or employee of a foreign government or any department, agency or instrumentality thereof.” In August 2014, the government’s broad definition of who constitutes a “foreign official” came into question for the first time when two individuals (Joel Esquenazi and Carlos Rodriguez) filed a petition for writ of certiorari with the Supreme Court to challenge their convictions under the FCPA and argued for the high court to limit the FCPA’s definition of the term. However, on October 6, 2014, the Supreme Court declined to consider the potential landmark case effectively upholding the government’s broad view of the term “foreign official.” READ MORE

SEC Bats 0-for-2 on Insider Trading

Judges Gavel

A California federal jury sided against the U.S. Securities and Exchange Commission on Friday, June 6, finding the founder of storage device maker STEC Inc. not guilty on insider trading charges.  This is the second insider trading loss in a week for the SEC, following a May 30 defeat in which a New York federal jury rejected insider trading allegations against three defendants, including hedge fund manager Nelson Obus.

In STEC, the SEC alleged that founder Manouchehr Moshayedi made a secret deal with a customer to conceal a drop in demand in advance of a secondary offering.  According to the complaint, Moshayedi knew that one of STEC’s key customers, EMC Inc., would demand fewer of STEC’s most profitable products than analysts expected.  The SEC alleged that he then made a secret deal that allowed EMC to take a larger share of inventory in exchange for a steep, undisclosed discount.


For Whom the Statute Tolls? A California Court Refuses Equitable Tolling for RMBS Claims

Map and gavel

A recent decision dismissing an RMBS lawsuit in the Los Angeles County Superior Court highlights the critical importance of filing your claims in the correct court whenever there is a jurisdictional issue.  By rejecting the plaintiff’s equitable tolling arguments and applying the appropriate statutory limitations periods, the decision is notable because it arguably conflicts with similar decisions by other state courts involving similar RMBS claims.  We have previously written about the application of statutes of limitations to RMBS claims, which may be viewed here.
