Fees and Compensation — Form ADV Part 2A (3/27/2026) [Brochure]
Item 5 - Fees and Compensation
The specific manner in which fees are charged is established in a Client’s written agreement with
MIAS. While at times MIAS may negotiate rates other than specified below, the following are the
Firm’s standard billing rates:
Financial Planning
MIAS normally will prepare or update a comprehensive financial plan and be on retainer to the
client for additional advice throughout the year. In such case, the normal fee ranges from $5,000
to $15,000, depending on the complexity of the Client’s financial situation. Under certain
circumstances, however, this fee structure may be adjusted, depending on the needs of the Client.

 $100,000,000 or above                             0.40%

Clients may reduce the first-year fee otherwise charged by electing a statement of intention
indicating the expected aggregate contributions to the account at the end of the initial 13-month
period (the "Target"). If a statement of intention Target is elected, the Client is able to combine
all anticipated deposits to the MIMS accounts in the first 13 months in order to establish a lower
breakpoint at the beginning of the account relationship. Capital appreciation plus reinvested
dividends and interest will be counted toward the Target, while depreciation due to market
fluctuation will not be counted. Withdrawals during the initial 13-month period will reduce dollar
for dollar the amount of earlier deposits which would otherwise have been credited toward the
Target. If applicable, the Client's account will be charged retroactively at the end of the 13-month
period for the difference between the actual fee paid under the statement of intention and the
fee which would otherwise have been charged without the statement of intention.

Fee Negotiation and Aggregation of Accounts
Fees are generally not negotiable, however, MIAS may negotiate certain fixed rates with Clients
that can apply to all asset levels. Similar Client accounts may have different fee schedules based
on the historical nature of the accounts or through negotiation with the Client. The Firm provides
advisory services to Clients with large portfolios in a limited number of special situations for
substantially reduced advisory fees.
For fee calculation purposes, MIAS may agree to aggregate the assets of related accounts that
are being managed for the same Client or in connection with a common familial or third-party
relationship. In such circumstances, the aggregated accounts will receive the benefit of a lower
effective fee due to the total amount of assets being managed. MIAS may also agree to enter into
temporary fee waivers or discounts with Clients. Any such negotiated fee arrangement is done
at the sole discretion of MIAS and is entered into generally without notice to, or consent from,
any other Client.
Our fees may be higher or lower than fees charged by other financial professionals offering
similar services. Our investment advisory contracts generally reserve us the right to modify a
Client’s fee schedule in the future by providing Clients with 30 days’ prior written notice of any
modification.
Fee Billing
Financial Planning Clients
Unless otherwise agreed to in writing, one-half of the financial planning fee will be due and
payable at the commencement of the relationship, but in no event later than thirty (30) days after
the date of execution of a Financial Planning Agreement. Two additional payments, each for one-
fourth of the fee, will be due and payable by the fourth and eighth months of the relationship,
respectively. In the event of termination, a refund will be made of that portion of any pre-paid
fees allocable to services paid for by the Client, but not rendered to the Client, and in excess of
reasonable start-up expenses. Either party may terminate the relationship upon thirty (30) days
