Retirement plan solutions built for fiduciaries
We deliver disciplined 3(38) and 3(21) investment services through scalable, technology-enabled solutions designed to reduce fiduciary risk and meet the evolving needs of retirement plans.
Investment oversight
The Grade Point Average (GPA)1 algorithm applies a disciplined, data-driven process to evaluate, select, and monitor investments, helping retirement plan sponsors meet fiduciary responsibilities.
Powered by innovative technology that analyzes a broad range investment types quarterly, decisions are made in the best interests of participants with oversight from our investment committee.
Plan reporting
The GPA System provides plan sponsors with quarterly reporting, delivered through a secure, cloud-based platform.
All data is encrypted, protected by two-factor authentication, and backed by a redundancy policy to ensure security and continuity.
Operational support
A dedicated onboarding team—supported by sales, investment and service representatives—works directly with financial advisors to ensure seamless transitions.
Each quarter, advisors and plan sponsors are notified of any changes within the GPA Report, and our team coordinates directly with recordkeepers to implement any investment changes.

Financial advisors stay focused on their core services by partnering with our team and leveraging our investment infrastructure. We offer flexible service models designed to meet client needs.
Together, we deliver scalable solutions—including reporting and distribution—that help reduce investment and operational burden and enhance client outcomes.

Customized
We recognize that every retirement plan is unique. We work with you to create a customized investment lineup while providing fiduciary protection.
For discretionary accounts, all investment decisions are made in-house using the disciplined GPA System.
