We try very hard to avoid all conflicts of interest. 

We never charge commissions of any kind.  We are paid only by fees earned as a percentage of assets or on an hourly basis for consulting work.  Commissions can encourage the less scrupulous advisor to generate excessive trades.  (Clients will pay commissions to whichever broker executes the trade but never to PWM.)

We never take any fees from any third party.  We do not receive fees from mutual fund companies (such as 12b-1 fees) for directing our clients to their products.  We are paid by the client only.   Therefore we have only the client's interest in mind. 

We do not use 'soft dollars'.  Soft dollars are fees that a manager can 'earn' by directing trades through a particular broker at a pre-arranged rate.  These fees are often used to pay for third-party research.  Some argue that such deals can encourage the manager to choose the broker based on how many soft dollars the broker offers rather then on which broker can achieve the best execution for the client's trade.
