SEC Moves to Close the Western Asset Cherry-Picking Case: What Private Fund Managers Should Check in Their Allocation Policies

On 6 October 2026 the SEC moved for entry of a final judgment, by consent, against Stephen Kenneth Leech II, the former co-chief investment officer of Western Asset Management Company. The judgment is subject to court approval, and Leech neither admitted nor denied the allegations. The SEC is seeking a $3 million civil penalty, an officer-and-director bar, a permanent injunction against violating the federal antifraud provisions and an associational bar whose terms are still to come. The case is about bond portfolios, but the conduct it describes, deciding who gets a good outcome after you can see it, is a risk for any adviser that splits deals between funds, co-investment vehicles and sidecars.

What the SEC said happened

The SEC filed its complaint in November 2024. It alleged that from at least January 2021 through October 2023 Leech placed trades and then delayed allocating them until near or after the daily settlement prices for the relevant futures were set. That let him see how the prices had moved and then allocate hundreds of millions of dollars of first-day gains to favored portfolios and a similar amount of first-day losses to disfavored ones. The SEC did not give a single dollar figure for the gains.

In June 2026 the SEC settled administrative proceedings against the firm. Western Asset agreed to a $100 million civil penalty and to a fair fund for investors in the disfavored portfolios. The order found that the firm had failed to take reasonable steps to detect and prevent the conduct and that it had willfully violated the Advisers Act antifraud provisions. Taken together with the Leech resolution, the SEC said $103 million would go back to harmed investors. By our arithmetic the firm's penalty is 97.1% of that total and Leech's is 2.9%. Separately, Leech pleaded guilty in June 2026 in federal court in New York to obstruction of justice, which relates to false and misleading testimony he gave to the SEC, and sentencing is expected in the coming weeks.

How this compares with the other recent SEC items we have covered

This is the sixth SEC item for private fund managers that we have written up since 4 October. Besides the new exam handbook, the 19 November compliance seminar with the Enforcement Division's Asset Management Unit and the capital call forfeiture case, we covered the proposals on performance fees and on the custody rule. Of the six, 2 of 6, or 33%, are enforcement outcomes and 4 of 6, or 67%, are guidance, outreach or proposals. None of the six has changed a rule that applies to a manager today. The common thread is that examiners and enforcement staff are looking at how a manager documents decisions, not only at what the decisions were.

Why this matters to a private fund manager

Allocation conflicts are not limited to bond desks. A private equity or venture manager decides which fund takes a deal, how much goes to a co-investment vehicle or sidecar, and how expenses are shared when a deal is broken. Our note today on Pennsylvania SERS's commitment to a flagship fund plus a sidecar shows how common that pairing has become, with 3 of the 4 named private equity decisions we reviewed including a sidecar or co-investment vehicle. Every one of those structures creates a place where an allocation decision can favor one investor group over another, and the investors in each vehicle will want to know the rule that was applied.

What fund managers should do now

This section is our advice and not something the SEC said. First, write down the allocation rule. State how an opportunity is split between funds, co-investment vehicles and sidecars, who decides, and what the default is when the rule does not give a clear answer.

Second, fix the allocation before the outcome is known. Record the decision with a time stamp before signing or closing, and require a written reason and a second approver for any change made afterwards. The conduct alleged in the Western Asset case turned on allocating after the result was visible.

Third, test the pattern over time. Ask the chief compliance officer to review each quarter whether any one fund or vehicle consistently receives the better deals, the larger share or the lower expenses. A single allocation can be explained, and a pattern is what an examiner would look for.

Fourth, give compliance real access. The firm's $100 million penalty rested on a failure to supervise, not only on one person's conduct. Compliance should be able to see allocation records directly, not through the person who made the allocation, and should have a clear route to escalate.

Fifth, check that the document matches the practice. Read the limited partnership agreement, the conflicts language and any process that requires a limited partner advisory committee to approve a cross-fund transaction, and confirm that what the team does is what those documents say.

Sixth, treat requests from the regulator seriously and consistently. The criminal plea in this matter concerned testimony given to the SEC. Keep records accurate and complete, and speak to counsel before any staff interview.

What to watch next

Watch for the court's decision on the consent judgment, for the terms of the associational bar, for the sentencing date in the criminal case and for the 19 November compliance seminar, where private fund topics are on the agenda.
