The former co-chief investment officer of Western Asset Management admitted to lying to regulators, ending a case that alleged he misallocated $1.2 billion in trading profits and losses.
Ken Leech, the former star bond manager at Western Asset Management, pleaded guilty Friday to obstructing a Securities and Exchange Commission investigation, days before his trial was set to begin on charges he cherry-picked $600 million in winning trades for favored clients while shifting $600 million in losses to others.
"Leech willfully and intentionally gave false and misleading testimony to the SEC in an effort to obstruct an investigation into his fraudulent scheme to favor certain clients at the expense of others," said Sean Buckley, deputy U.S. Attorney for New York's Southern District.
Leech, 72, pleaded guilty to a single count of obstructing a regulatory proceeding, carrying a maximum sentence of five years. The original charges — securities fraud, investment adviser fraud, commodities fraud and making false statements — each carried up to 20 years and were dropped as part of the plea. Under federal sentencing guidelines, Leech faces between six and 12 months in prison, according to Reuters. Sentencing is scheduled for Sept. 21.
The plea closes a criminal chapter for one of the bond industry's most prominent figures, who retired from Western Asset Management in August 2025 after being placed on leave. The firm, a subsidiary of Franklin Templeton that managed about $229 billion at the end of March, agreed last week to pay a $100 million civil penalty to the SEC to settle allegations it failed to supervise Leech. The Justice Department notified the company last year it would not face criminal charges.
The alleged scheme ran from January 2021 to October 2023. Prosecutors said Leech placed trades and then waited until later in the day to allocate them to client accounts, after seeing how the trades had performed. Winning trades went to preferred clients while losing trades were directed to others, according to the government.
Leech gave false testimony under oath during an SEC deposition in March 2024, including when he answered "yes" after being asked whether he had "an allocation in mind" when making trades, prosecutors said. "I knew that I was giving false and misleading testimony about my trade allocation process, and that giving that testimony was wrong," Leech told the judge Friday, according to the Financial Times.
The SEC's civil case against Western Asset highlighted what the regulator called a failure of oversight. In a filing, the SEC said the fixed-income group was "aware" that Leech's trading and allocation practices "diverged from those of other portfolio managers" but failed to take reasonable steps to detect and prevent the conduct.
The case highlights the regulatory scrutiny facing asset managers over trade allocation practices. Cherry-picking — allocating profitable trades to certain accounts after seeing their performance — has been a focus of SEC enforcement actions in recent years, with the agency pursuing cases against both individuals and firms for inadequate supervision.
