* ShareBuilder 401k plan expenses range from 23% to 68% less than the industry average at various data points from a $50K plan with 6 participants to a $100M plan with 2,000 participants based on 401k Averages Book 2023 Data and Custom Benchmarking report prepared for ShareBuilder Advisors. Cost comparisons are based on plan assets and number of participants and reflect core on‐going 401(k) plan expenses that a company and/or its employees can expect to incur as a percentage of assets with most any 401(k) plan. This includes administration, recordkeeping, tax filing prep documents, plan testing, fund expense ratios, and other investment costs passed on to every participant to service the plan. It does not include unique employee-initiated transactions such as loans, distributions or employer transactions such as plan amendments. ShareBuilder 401K pricing is based off of standard pricing rates for our typical Safe Harbor 401(k) plan design. This claim is not applicable to solo 401(k) plans.

1 High-quality Funds: The ShareBuilder Advisors Investment Committee conducts an annual review of the Exchange-Traded Funds offered as ShareBuilder 401k investment options. The review includes multiple variables including length of time since inception, asset level, historic performance over one to ten years, expense ratios, and how the funds compare to their respective benchmark index. Each fund is monitored and changes are made to the fund lineup as needed to align the investment options to the Investment Committee’s investment policy.
