These are some important points in helping you understand how you and HCM will work together...

1. We Don't Take Your Money. 

Your money is held at Fidelity Investments, a major brokerage house chosen by Dimensional Fund Advisors as one of its select Custodians.  If your money is already at Fidelity, your portfolio will remain at Fidelity although your accounts will be moved within Fidelity to the "Institutional" side of the business.

Fidelity has been chosen by Dimensional Fund Advisors as one of its preferred Custodians for its execution ability, financial strength, and low cost.

2. You Name HCM As Your Advisor And Give HCM "Trade Authorization." 

HCM will be given authority as your Advisor to execute trades necessary to implement the Investment Plan that you will have agreed to.  The number of these trades will vary depending on the number of accounts you have and your current holdings.  For most people there will be approximately 10-20 transactions in order to construct your portfolio.

HCM will not have the ability to withdraw funds from your accounts (except for Fees), nor do we want that ability.  This is a fee-for-service business and we keep it as simple and arm's length as possible.

3. HCM Can Either Invoice You For Our Services, Or, If You Choose, We Can Deduct Fees From Your Account.

4. You Will Have Direct Access To Your Portfolio At All Times.

Fidelity Investments has excellent Internet access to Client accounts.  Your access to information about your account(s) is equal (or greater) to any retail customer of Fideltiy.
