Harding Loevner and Schafer Cullen offer Parametric Custom Active strategies

SEATTLE--(BUSINESS WIRE)--Parametric Portfolio Associates LLC (Parametric), part of Morgan Stanley Investment Management (MSIM), today announced new partnerships with Harding Loevner and Schafer Cullen Capital Management to deliver the Custom Active solution, an innovative tax optimization capability for active equity managers. Parametric expanded its Custom Active offering with more than 16 new strategies added year-to-date across its partner network and now includes MSIM’s Applied Equity Advisors suite of strategies.

The Custom Active platform comprises 65 strategies from investment teams at MSIM and third-party asset manager partners and represents more than $12.5 billion in assets under management as of December 1, 2025. All active equity strategies available on the Custom Active platform are tax-managed by Parametric and can be customized to address investor preferences.

“The strong momentum we’ve seen for the Custom Active platform reflects robust investor demand and a broader recognition that tax management combined with active management is a key consideration for investors,” said Tom Lee, Co-President and Chief Investment Officer at Parametric. “We are thrilled to integrate new partners and strategies into our platform and recognize that our success hinges on bringing tax management expertise and portfolio implementation to highly sought after industry strategies.”

Tax Management Drives Adoption
A new Cerulli Research study released in October 2025 revealed that nearly 80% of affluent investors agree that tax-aware portfolio customization is important to meet their specific situations and shaping the future of wealth management. Moreover, it indicated that scalable, tax customization is rapidly becoming a baseline expectation not just for high-net-worth (HNW) clients, but increasingly for investors of all levels.

“We consistently hear from advisors and their clients that they are looking for bespoke solutions that are more tax efficient,” said Matt Witkos, Head of North America Intermediary Sales, MSIM. "Parametric’s deep expertise with tax optimization and customization creates a unique opportunity to expand how advisors address the growing client demand for differentiated strategies that align with core needs.”

Parametric’s Custom Active solution is designed to meet sophisticated investment objectives through actively managed separately managed accounts (SMAs) tailored for tax efficiency and other strategic considerations. The SMAs also offer additional customization opportunities including sector and industry screens, and client-directed gain/risk budgets. More details are available on the Parametric Custom Active website.
