Fee Disclosures

The firm offers clients two different fee structure options, one based solely on client assets under management (Traditional Fee), or one based on a combination of assets and performance (Performance-based Fee). While the performance-based fee structure aligns the interests of management with those of the client’s results, it may create an incentive for the firm to recommend riskier investments to generate higher returns. Further, since the firm also manages client accounts that do not pay performance-based fees, it may create an incentive for the firm to favor performance-based fee accounts. However, as a fiduciary, the firm aims to act in the best interest of its clients and subscribes to managing traditional fee and performance-based fee clients in a similar fashion.

*In order to select our performance based fee, the Client must be a “Qualified Client” within the meaning of the US Securities and Exchange Commission Investment Advisors Act of 1940, rule 205-3 as amended.  This criterion would include either a total net worth of $2,200,000 or assets under management with Main Street Research LLC of $1,100,000 or more. A minimum investment is required – please inquire.
