Fiduciary Plan Services

Our fiduciary services are designed to provide dedicated support to your business. As a 3(38) Investment Manager, we take full discretion and responsibility for the investment decisions in your plan, ensuring that your investments are continuously scored, monitored, and aligned with your Investment Policy Statement. For those seeking more of a “co-partnership” approach, our 3(21) Co-Fiduciary service allows us to score and monitor your fund lineup to give recommendations to your retirement plan committee.

Additionally, our team will assist you in creating your Investment Policy Statement (IPS) that outlines the strategic vision of your retirement plan, the process, and the parties involved. We assist in both the benchmarking and negotiation of your provider’s fees and services. Mainstreet RIA LLC will work with your existing recordkeeper to help implement a targeted educational program for your participants, and with your TPA to explore the latest law changes and opportunities.

Fund Lineup Services

At Mainstreet RIA LLC, we differ from the competition in a few ways:

  • While most of our competition charges fees based on a percentage of plan assets, we charge our fees on a flat annual basis.

  • We also use different fund scoring criteria that depend on the type of fund, where many in our industry apply the same set of scoring criteria no matter the type of fund, whether Equity, Fixed Income, Allocation, or Index.

  • Finally, we do not use 10-Year Performance and Risk criteria because we feel that it can keep a fund as passing, even if that fund has been consistently scoring low in its respective peer group over the past few years.

  • These factors allow Mainstreet RIA LLC to accurately and effectively monitor your investments, ensuring you receive the most precise data and recommendations.

Our Investment Monitoring Process

Mainstreet RIA LLC is your partner in investment management, and our experts can help you build an investment strategy that fits the unique objectives of your company and employees.

1. Gathering Data

We first gather the list of available investments from your recordkeeper, applying our criteria to the funds to determine which are passing with a score of 70 or higher.

2. Reporting

Our Quarterly Monitoring Report (QMR) shows the quarterly score for each fund for the past 12 quarters, providing a historical view that helps to show the fund’s consistency. Our report also shows where a fund is specifically outperforming or underperforming its peer group, helping us understand fund divergences and allowing for meaningful discussions between our team and the fund manager.

3. Monitoring

Each quarter, we send you an updated QMR report, whether you select ERISA 3(21) or 3(38) services. As we periodically review your fund offerings, we will benchmark investment performance and expenses to help you gain a clear picture of your investments.
