Prime Brokerage Legal Solutions

Who We Are

Harry Jho LLC is a law firm specializing in prime brokerage, ISDA-documented OTC derivatives and securities finance. The Firm is a trusted advisor for banks, hedge funds and industry groups seeking to manage their trading agreements and counterparty risk. 


We have advised every single new entrant in the equity prime brokerage industry in the last 10 years in the launch of their business.

The Firm’s leading role in the equity derivatives markets is reflected in its long-time representation of the International Swaps and Derivatives Association, Inc. (ISDA). Most of the flow ISDA-documented OTC equity derivatives contracts in use today are based, in whole or in part, on forms produced by the Firm. 


We provide end-to-end documentation and negotiation support for the full suite of trading and financing documents, from high-volume flow products to highly bespoke T1 client arrangements. Depending on client needs, we can integrate with Legal / Documentation, Sales, Credit, New Business or Front Office to provide an in-house level of service during any market condition.

Prime Brokerage

Our experience in prime brokerage is unmatched on the street. We cover the full suite of prime brokerage agreements, including basic account agreements, committed facilities and margin and pricing schedules.

We are the industry leader in negotiating complex term margin facilities, integrating across multiple product lines.

We can work with Legal and Treasury to ensure your committed facilities are tailored to the structure of your business. We can also help determine the best approach to protect your documentation before the next market event, whether remedial rights in respect of a portfolio, guarding market access, or a managed unwind process, and lock those terms into your documentation.



We cover everything from complex ISDAs structured to work with term margin facilities, to flow corporate ISDAs linked to syndicated loans. We are active in UMR (Reg IM and Reg VM) and other regulatory re-papering initiatives.


Our expertise in ISDA-documented OTC Equity Derivatives is unparalleled. As ISDA’s counsel, we drafted the documentation and led the working groups that produced the current industry-standard Master Confirmation Agreements used for the flow trading of equity swap and options products in the US and Europe.

We have also been advising ISDA on their next-gen equities documentation systems to integrate with fintech solutions and blockchain technologies. We have experience with emerging market long form confirmations, exotics, and bond confirmations.

Our documents include the 2009 European Interdealer Master Equity Derivatives Confirmation Agreement (covering options, accrual swaps and fair value swaps for index and single share transactions) and the 2009 Americas Master Equity Derivatives Confirmation Agreement (covering options, listed lookalikes and accrual swaps for index and single share transactions).

We are proud to be featured in the ISDA Member Showcase of service providers that offer products and services for the derivatives industry.

Most of the equity confirmation documentation used by the industry today was drafted, in whole or in part, by our Firm.

Why Us?

Seamless In-House Support

We place great importance on understanding the business and operations of trading firms. We are often engaged to provide support on an ongoing basis to a client’s operations group, in addition to their legal team. By understanding the needs of the in-house attorneys who we support, we can tailor our work product to provide maximum leverage.

We are designed to support in-house counsel and to mirror the in-house legal department of a trading firm. Our attorneys advise and leverage in-house legal; our Analysts function like documentation units at major dealers.

Unlike the documentation temp agencies, our Analysts work under the close supervision of senior staff, which ensures consistency and quality in their work product. And unlike junior associates at
traditional law firms, our Analysts focus exclusively on trading issues from their first day on the job.

Separate Buy / Sell-Side Practices

We operate two separate and independent practices, the Dealers Team and the Funds Team, with common back office and management. Each practice has its own Analyst team, with physical and informational walls between them, including separate computer systems. Each team is under the supervision of separate Partners (Lawrence Wu for the Funds Team, Todd Blanke for the Dealers Team). Harry Jho, our Managing Partner, and Karl Fey, our COO, are the only professionals who sit above the wall. This allows us to maintain confidentiality and independence between the two teams while pooling our resources for hiring, training, and administration.


In addition to working alongside our Partners, who have worked in-house at the major dealers and have a deep understanding of the business and operations of trading firms, our Analysts undergo a rigorous training program, which has been developed in-house over the last decade.

After completing the training program, Analysts are frequently seconded to work on-site with both buy- and sell-side clients.

Security & Data Storage Management

We take great pride in providing a secure environment to house our clients’ documentation and private data. In addition to physical separation, our operation has implemented information barriers between the Dealer and Funds Teams, including restricted file access between the teams, separate email domains and separate data storage security groups.

Harry is a frequent speaker on topics relating to derivatives and prime brokerage.

On the sell-side, Harry has advised major prime brokers in structuring their product platforms and drafted the form of prime brokerage agreement used by many dealers in the business. Harry has also advised prime brokers on both how to streamline their client on-boarding processes and matters relating to the exercise of default remedies.

On the buy-side, Harry has helped several major hedge funds implement their documentation strategy with respect to their trading platforms, ensuring they have market access during times of crisis.

For the industry, Harry has drafted the form of Master Confirmation Agreement published by ISDA with respect to various equity swap and option products traded in the US and in Europe, the 2011 ISDA Equity Derivatives Definitions and the Equity Matrices.

Harry has trained several generations of professionals, many of whom are now in senior leadership positions in legal departments across the industry.
