Kenneth Leech II, former co-chief investment officer of Western Asset Management Company, pleaded guilty on June 12, 2026 to obstruction of an SEC investigation, admitting in a Manhattan federal court that he provided false and misleading testimony to agency examiners, according to a DOJ press release.

The plea resolves the criminal side of a case that had been building since the SEC charged Leech with fraud on November 25, 2024. Under the terms of the deal, the fraud counts were dropped in exchange for the obstruction guilty plea. Federal sentencing guidelines recommend a custodial term of six to twelve months — a relatively narrow range that reflects the single-count nature of the plea rather than the full scope of the underlying conduct alleged.

The Cherry-Picking Allegation

The predicate conduct at issue was a cherry-picking scheme — a practice in which a portfolio manager allocates profitable trades to favored accounts after execution, while directing losing positions elsewhere. Because allocation decisions are made post-trade, cherry-picking is difficult to detect in real time and can persist across extended periods before patterns surface in statistical analysis. It is, structurally, a breach of best-execution and fair-allocation obligations owed to every affected client.

WAMCO is a fixed-income manager of considerable scale, running assets across institutional mandates including insurance, pension, and retail fixed-income strategies. Differential allocation at that level of AUM can translate losses to ordinary pension beneficiaries and insurance policyholders who never see a trade ticket.

The Obstruction Charge and What It Means

Leech's guilty plea covers not the cherry-picking itself but the lie told to conceal it. That sequencing matters. Obstruction charges are often a prosecutorial tool when the underlying substantive case — here, securities fraud — presents evidentiary complexity or requires proving intent across thousands of individual allocation decisions. A false-testimony count, by contrast, is cleanly bounded: the statement was made, it was material, it was false.

The consequence for Leech is that while the fraud charges have been set aside, a federal conviction still lands on his record. The recommended guideline range of six to twelve months leaves the sentencing judge meaningful discretion, and white-collar obstruction cases at this level can attract probation or home confinement rather than incarceration — particularly absent the fraud conviction. No sentencing date was cited in the DOJ release.

WAMCO's $100 Million Settlement

Separate from the criminal proceeding, WAMCO accepted a $100 million civil penalty from the SEC in connection with the same conduct. A nine-figure penalty is not routine for an asset manager; it signals that regulators assessed the harm to clients as material and that the firm's supervisory failures were significant enough to warrant more than a symbolic fine.

For Franklin Templeton, which acquired WAMCO's parent Legg Mason in 2020, the settlement closes a legal liability that had been overhanging the business and likely contributing to client attrition in the affected strategies. The financial hit is discrete and quantifiable. Reputational repair is a slower process.

The broader lesson for compliance officers and risk committees is structural. Cherry-picking schemes at major fixed-income houses typically involve large numbers of accounts and hundreds of individual allocation events. Robust post-trade allocation monitoring — statistical analysis of realized P&L distribution across accounts by portfolio manager — is the standard detection mechanism, and the WAMCO case will likely refresh its priority in compliance reviews across the industry. The SEC's willingness to pursue both a criminal referral and a nine-figure civil penalty against the firm signals that allocation surveillance is an active examination focus, not a checkbox item.

Leech's sentencing date has not yet been set.
