Investment Discretion in 13F: SOLE, DFND, OTR Decoded

Most retail readers skim the rightmost columns of a 13F. The dollar value and share count tell the story, the CUSIP identifies the stock, and everything else looks like SEC plumbing. Investment Discretion sits in that overlooked block, and it carries three codes that quietly tell you who actually controls each position: SOLE, DFND, or OTR.

The codes mean exactly this: SOLE means the filer has sole investment discretion; DFND is short for "defined" discretion, shared with another reporting manager under a written agreement; OTR is "other" discretion, the catch-all for jointly held control that does not fit the first two. Each label appears per row, alongside the Voting Authority columns that most explainers stop at.

Treat the codes as a structural map, not a conviction signal. A SOLE label tells you one manager runs the book. A DFND or OTR label tells you the position lives inside a multi-manager, sub-advised, or platform structure where someone else is sharing the call. None of the three says anything about whether the filer likes the stock.

The Three Codes, Step by Step

SOLE — One Filer, One Decision

SOLE means the reporting manager exercises sole investment discretion over the holding. No other manager appears on the row, and the cover-page "Other Managers" table does not need to be referenced for that line. This is the default code for self-contained shops where one investment team runs the entire 13F book.

Most well-known single-shop managers file SOLE on the vast majority of their rows. Berkshire Hathaway, Bridgewater Associates, and Renaissance Technologies are typical: one filer, one team, one decision-maker per position. When you see SOLE across a 13F, the filer is the end-of-the-line decision-maker.

DFND — Defined Discretion, Shared Under Agreement

DFND is short for "defined." It is used when investment discretion is shared with one or more other reporting managers under a written agreement — typically a sub-advisory contract, a defined sleeve of a master-feeder vehicle, or a documented relationship with a parent adviser. The cover page's Other Managers column then carries a numeric reference pointing to the named co-manager.

DFND is the common code in master-feeder structures and sub-advisory chains. The position belongs to the reporting entity, but a separate manager — also a 13F filer — has a defined slice of the decision. Both managers may end up reporting the same row, each with a DFND label, which is why double-counting across filers is a real risk if you sum without checking the discretion codes.

OTR — Other Discretion, The Catch-All

OTR means "other." The SEC uses it when discretion is shared jointly with someone whose relationship to the filer does not fit the SOLE or DFND molds. It frequently shows up when the discretion is jointly held with the underlying client, a non-13F-filing party, an offshore parent, or a custodial relationship.

OTR is also common at pod shops and multi-manager platforms. Millennium Management, Citadel Advisors, and Point72 Asset Management all run dozens of internal trading pods or sub-advisers with overlapping mandates. The 13F has to reflect the joint-discretion reality, and OTR is how the SEC says "complex internal structure" without spelling out every relationship.

Investment Discretion vs Voting Authority

These two columns sit next to each other but answer different questions. Investment Discretion answers who decides to buy or sell? The Voting Authority columns (Sole, Shared, None) answer who casts the proxy vote at the next annual meeting?

The two often line up, but not always. A sub-adviser can hold defined investment discretion (DFND) over a stock while voting authority sits with the parent fund — or the reverse. When you are reading a 13F to gauge corporate-governance influence, the voting-authority fields are what to check. When you are reading it to gauge who actually picked the stock, Investment Discretion is the field that matters.

Why Multi-Manager Platforms Mostly File DFND or OTR

The pod-shop business model splits capital across dozens of internal portfolio managers (PMs), each running an independent sleeve under one legal filer. The PM picks the stock; the central platform sets risk limits and capital allocation. Discretion is, by design, shared.

That is why the largest multi-manager 13Fs show heavy use of OTR or DFND across their rows. Citadel Advisors and Millennium each report books well over $200B in 13F value backed by a wide trading bench. Each pod's PM has the discretion to put on the position, but the platform itself sits on top of the legal mandate — the row is jointly controlled in a way SOLE would misrepresent. This is structural, not a signal that the platform is hedging or has low conviction.

Quant filers like Two Sigma Investments or Renaissance Technologies, by contrast, often file SOLE despite running thousands of model-driven positions, because one legal entity runs the strategy end-to-end. The lesson: discretion codes describe the organizational chart, not the strategy. See the quant vs discretionary distinction for the deeper read.

What the Code Does Not Tell You

Three reader mistakes are common:

• It is not a conviction meter. SOLE is not "high conviction" and OTR is not "low conviction." A pod-shop OTR on Nvidia (NVDA) can be the largest position in a particular PM's book — the code only describes who shares the call.
• It is not a size signal. The size of the position is in the Value and SH/PRN Amount columns. SOLE on a $50,000 position and SOLE on a $5B position carry the same label.
• It does not validate notional vs invested capital. When a row carries a PUT or CALL label in the adjacent Put/Call column, the reported Value is a notional/market-value figure, not invested capital. Adding up SOLE-discretion option notional and calling it "managed AUM" is a classic misread of options-heavy filers, where the dollar number reflects hedged exposure or notional, not directional cash invested.

How to Find the Investment Discretion Column on a Real 13F

SEC 13F-HR filings follow a standard Information Table layout. From left to right:

1. Name of Issuer
2. Title of Class
3. CUSIP
4. Value (in U.S. dollar thousands)
5. SH/PRN Amount
6. SH / PRN code
7. PUT / CALL (blank if not an option)
8. Investment Discretion (SOLE / DFND / OTR) — this column
9. Other Manager (numeric reference to the cover-page "Other Managers" table)
10. Voting Authority — Sole / Shared / None

On 13F Insight, the discretion code is preserved per holding so you can sort or filter. Combine it with the pod-shop reading above and the discretionary-vs-quant distinction to keep multi-manager flows from being misread as a single-team conviction trade.

Common Misreads

• Double-counting across DFND filers. If two managers share defined discretion over the same position, both file the row. Aggregating across both inflates the apparent institutional holding. 13F thresholds and the Other-Managers cover page exist in part so you can de-dupe.
• Labeling market-maker affiliates as "smart money." Market-maker arms such as Susquehanna Financial Group file 13Fs that reflect hedged inventory, not investment conviction. The discretion code is often SOLE, but the underlying business model is dealer book-keeping, not directional bets. The same applies to other market-maker filers like Citadel Securities, Jane Street, and Virtu Financial.
• Reading SOLE on a passive index fund as a stock pick. An index-fund filer can carry SOLE across the entire book and own positions only because the index mandate forces it. SOLE is a legal label; the strategy still has to be inferred from filer type, not the discretion code.

FAQ

What is the Investment Discretion column on a 13F filing?

Investment Discretion is the column on the SEC Form 13F Information Table that records who has the authority to buy or sell each position. It contains one of three codes per row: SOLE, DFND, or OTR.

What does SOLE mean in a 13F filing?

SOLE means the reporting manager exercises sole investment discretion over the position. No other 13F-filing manager shares the buy/sell decision, and no reference to the "Other Managers" cover-page table is required for that row.

What does DFND mean in a 13F filing?

DFND stands for "defined" discretion. The reporting manager shares investment discretion with another reporting manager under a written agreement, typically a sub-advisory contract or a master-feeder relationship. The Other Manager column then names the co-manager.

What does OTR mean in a 13F filing?

OTR stands for "other" discretion. It is the catch-all the SEC uses when discretion is jointly held in a way that does not fit SOLE or DFND, often with a non-13F-filing party or a complex internal platform structure such as a pod shop.

How is Investment Discretion different from Voting Authority on a 13F?

Investment Discretion answers who buys or sells the position. Voting Authority — Sole, Shared, or None — answers who votes the proxy at shareholder meetings. They can differ when a sub-adviser picks the stock but the parent fund retains the vote.

Why do pod shops and multi-manager platforms show DFND or OTR?

Multi-manager platforms split capital across many internal portfolio managers under one legal filer. The PM picks the stock, but the platform sets risk and capital limits, so discretion is jointly exercised. DFND and OTR reflect that shared structure.

Does the Investment Discretion code show how high-conviction a position is?

No. The discretion code describes who shares the buy/sell decision, not how convinced the filer is about the position. Position size and quarter-over-quarter changes are the fields that signal conviction.

Where is the Investment Discretion column on a 13F?

On a standard 13F-HR Information Table, Investment Discretion is the eighth column from the left, between the Put/Call indicator and the Other Manager reference. On 13F Insight, the same code is preserved per holding on each filer's page.
